Detailed Description

The present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. The embodiments described above are intended to be illustrative of the full and complete disclosure of this invention, and thus, to provide a more complete and accurate understanding of the scope of the invention.

Terms such as "comprising" and "comprises" mean that, in addition to having components which are directly and explicitly stated in the description and claims, the solution of the invention does not exclude other components which are not directly or explicitly stated.

Terms such as "first" and "second" do not denote an order of elements or components in time, space, size, or the like, but rather are used merely to distinguish one element or component from another.

For convenience of explanation, x-direction, y-direction and z-direction are defined in fig. 1 to 17, wherein the direction of the height of the rail working vehicle/rail site normalizing operation system is defined as z-direction, the direction of the axle of the corresponding wheel set of the rail working vehicle/the width direction of the rail site normalizing operation system is defined as y-direction, and the x-direction is perpendicular to the y-direction and z-direction and is substantially along the direction of the track on which the wheels of the rail working vehicle travel/the direction along the length of the rail site normalizing operation system; for convenience and clarity of description, the forward direction in the x direction is directed to the rear/tail end of the rail vehicle, i.e., to the field operating point of the rail field normalizing operation system, and the forward direction in the y direction is directed to the right side of the rail vehicle. Also, in the following description with respect to fig. 1-17, "front/head" and "back/tail" are defined with respect to the x-direction, "left" and "right" are defined with respect to the y-direction, and "up" and "down" are defined with respect to the z-direction. It should be understood that these directional definitions are for relative positional description and clarification, and may vary accordingly with changes in orientation of the rail work vehicle/rail field normalizing work system, etc.

A rail working vehicle 20 and a rail field working assembly 1000 according to an embodiment of the present invention will be described below with reference to fig. 1 to 9. The rail work vehicle 20 is capable of traveling along a track and may be used to carry one or more rail field work systems 10 to the site for either offline or online work; the on-line work and the off-line work are two work modes defined mainly for the placement position of the rail, the work in which the rail is placed on both sides of the track is called the off-line work, and the work in which the rail itself is pressed by the rail work vehicle 20 under the wheels is called the on-line work.

As shown in fig. 1 and 2, the rail working vehicle 20 may be implemented in the form of a rail flatcar, in which a frame 21 as a rail working vehicle 20 main body is formed with a substantially flat-plate-type plane on an upper surface thereof for carrying the rail field working system 10, and thus may also be referred to as a "rail flatcar". The dimensions of the rail working vehicle 20 in the x-direction and the y-direction may be designed depending on the size and/or number of rail field work systems 10 it carries. The rail working vehicle 20 further comprises wheel sets, and the frame 21 is supported by the wheel sets; generally, the wheelset includes an axle 233 and wheels 231 provided at both left and right ends of the axle 233, respectively, and the wheelset can travel on a rail by the two wheels 231.

As shown in fig. 1 and 2, the rail working vehicle 20 further includes an electric transmission assembly disposed corresponding to the wheel pair, and a traction motor 221 outputting power to the electric transmission assembly, wherein the traction motor 221 may be fixedly disposed on a cross beam of the frame 21, and the traction motor 221 and the electric transmission assembly may drive the wheels 231 to travel on the rail, so that the rail working vehicle 20 may travel by itself.

The applicant notices that the existing rail working vehicle 20 is generally provided with a dedicated diesel engine to directly drive the corresponding hydraulic pump to output power so as to drive the rail working vehicle to run, and the rail field normalizing working system 10 carried by the rail working vehicle 20 is also generally provided with a corresponding generator set for field operation. Traction motor 221 of an embodiment of the present invention is configured to obtain the power required to drive rail vehicle 20 to travel by itself by: in carrying the rail site operation system 10, the traction motor 221 is removably electrically connected to the generator set 12 in the rail site operation system 10 carried by the rail vehicle 20 such that power is provided to the traction motor 221 primarily or entirely through the generator set 12. Thus, the generator set 12 of the rail working system 10 to be carried, and even the corresponding diesel engine and the like can be shared by the rail working system 10 and the rail working vehicle 20, the rail working vehicle 20 does not need to be provided with a diesel engine and the like specially in the traditional way to drive the hydraulic pump and the like to output power to drive the rail working vehicle to travel; compared with the prior art that a special diesel engine is arranged for the rail working vehicle to directly drive a corresponding hydraulic pump to output power to drive the rail working vehicle to run, the rail working vehicle 20 provided by the embodiment of the invention does not need to be provided with the diesel engine and the like, even if the traction motor 221 and the electric transmission assembly are arranged on the rail working vehicle 20, the rail working vehicle can be realized at relatively low cost, is easy to accept by users, has a simple structure, requires a small installation space, and can realize electric drive.

It should be understood that the above "sharing" is made by the applicant considering comprehensively the application characteristics that the rail field operation system 10 does not need to apply power to perform field operation when being carried, and the rail field operation system 10 does not need to be driven by power to travel when performing field operation, so that the application requirements of the rail operation vehicle 20 and the rail field operation system 10 can be met at the same time, even if the "sharing" of the generator set 12 does not cause the problem of power demand contradiction between the rail operation vehicle 20 and the rail field operation system 10, the power of the traction motor 221 can be easily ensured, the high-power driving requirement of rail transportation can be easily met, and the driving range is not limited basically (for example, if the traction motor 221 is powered by a power battery module, the driving range and the power cannot meet the requirement of the rail field operation system 10 with large carrying weight easily). Moreover, the detachable electrical connection between the traction motor 221 and the generator set 12 in the rail field operation system 10 is also very easy to implement, for example, by a simple plugging operation between corresponding cable connector ends; in contrast, if a diesel engine is used to drive the rail working vehicle by outputting power from a hydraulic pump, it is very difficult to connect the diesel engine to a mechanical transmission assembly such as a hydraulic pump.

In one embodiment, as shown in fig. 2, the electric transmission assembly may include a transmission shaft 223 and a coupling 225, wherein the coupling 225 may be a universal coupling (e.g., a cross universal coupling), the transmission shaft 223 is located right above the axle 233 and crosses the axle 233 in a "cross" shape, one end of the transmission shaft 223 may be rigidly connected to an output flange of the traction motor 221, the other end of the transmission shaft 223 is connected to one end of the universal coupling 225, the other end of the universal coupling 225 is connected to an input end of an axle gear box 227 installed on the axle, and the universal coupling 225 works together with the axle gear box 227 and may output the power transmitted by the transmission shaft 223 to the axle 233 in the corresponding wheel pair; thus, the traction motor 221 can drive the axle 233 to rotate, thereby driving the wheel to rotate.

In another alternative embodiment, shown in FIG. 6, there are two universal couplings 225, namely

universal couplings

225a and 225b, which may be connected by a shaft therebetween; of course,

universal couplings

225a and 225b may also be considered as a universal coupling having two universal free ends, so that a drive shaft 223 as in fig. 2 may be required. Wherein the first universal coupling 225a is coupled (e.g., bolted) to the output of the traction motor 221 and the second universal coupling 225b is coupled (e.g., bolted) to the axle gear box 227. Therefore, the two ends are in universal free connection, so that damage to the axle gear box 227 caused by motor vibration, motor jumping or axial deflection and the like can be avoided, and the traction motor 221 and the gear box 227 can be protected.

Continuing with FIG. 2, in one embodiment, an electric drive assembly and traction motor 221 are provided for each set of wheel pairs, respectively. The wheel pair is 2 sets as an example, and the front and rear sets of wheel pairs are respectively and correspondingly provided with a transmission shaft 223, a universal coupling 225, an axle gear box 227 and a traction motor 221, so that the wheel pairs can be respectively driven. It will be appreciated that the number of wheel pairs may be increased as required, and the number of drive shafts 223, universal couplings 225, axle gear boxes 227, traction motors 221, etc. provided for the respective wheels may be increased accordingly.

Continuing with fig. 2, in one embodiment, the electric drive assembly (e.g., drive shaft 223, universal joint 225, axle gearbox 227) and traction motor 221 provided for a first set of wheel pairs and the electric drive assembly (e.g., drive shaft 223, universal joint 225, axle gearbox 227) and traction motor 221 provided for a second set of wheel pairs may be arranged substantially symmetrically along a centerline 2331 that is parallel to the direction of the axle 233 of the wheel pair, i.e., parallel to the y-direction, which may be midway between the two drive shafts 223. Thus, the reasonable layout and stable gravity center are realized.

Continuing with fig. 1 and 2, in one embodiment, a plurality of locking assemblies 212 are provided on the frame 21 of the rail vehicle 20, and the locking assemblies 212 are used to removably mount and lock the rail work site system 10 to the frame 21, such that the rail work site system 10 can be easily removed from the frame 21, for example, by using a large crane or other equipment to hoist the rail work site system 10 to the rail vehicle 20, aligning, locking, and otherwise removing the rail work site system 10 from the frame 21. When the rail work vehicle 20 is used to attach and detach the rail field work system 10, it is also possible to simultaneously and conveniently perform, for example, electrical connection or electrical removal between the traction motor 221 and the generator set 12; also, there is no need for an engagement operation between the transmission systems (which is often complicated).

The rail working vehicle 20 of the above embodiment can be used to carry any type of rail field working system 10 with a generator set by arranging the locking assembly 212, the corresponding traction motor 221 and the electric transmission assembly, and can also be used to carry different rail field working systems 10 of the same type, that is, the rail working vehicle 20 can carry a plurality of rail field working systems 10 respectively, thereby greatly improving the universality. In an embodiment, the rail field operation system 10 carried by the rail operating vehicle 20 may be a box type rail normalizing system, which has a container 11 with a container structure, and is convenient to carry integrally as a container, and the box type rail normalizing system may be used for completing field normalizing heat treatment operation for a rail, so as to improve the properties of the welded joint of the rail, such as toughness, and meet the corresponding standard requirements. It should be understood that the specific type, structure, etc. of the rail field operation system 10 carried by the rail working vehicle 20 of the above embodiment are not limiting, and in other embodiments, the rail field operation system 10 may also be a rail welding field operation system, a rail grinding field operation system, a welding inspection field operation system, etc.

In one embodiment, as shown in fig. 6 and 7, locking assembly 212 may include a twist lock 2121, a twist lock nut 2122, a washer 2123, and a cotter pin 2124; locking assembly 212 releasably lockingly mounts the housing 11 of rail field work system 10 to frame 21 of rail work vehicle 20 via twist lock 2121, twist lock nut 2122, spacer 2123, cotter pin 2124 and grooved boss 2125. Illustratively, as shown in fig. 6 (b), the boss 2125 may be fixed to the frame 21 (e.g., fixed to the frame 21 by welding), the rotary lock 2121 includes a head portion and a shaft portion having a smaller radial dimension relative to the head portion, the shaft portion of the rotary lock 2121 sequentially passes through the boss 2125 (corresponding through holes may be provided on the boss 2125), the cabin 11, the frame 21 (corresponding through holes may be provided on the frame 21), the gasket 2123 and the rotary lock nut 2122, and the rotary lock nut 2122 is screwed to the lower end of the shaft portion of the rotary lock 2121; the twist lock 2121, when rotated by a predetermined angle (e.g., 90 °) so that the head of the twist lock 2121 at least partially seats in the recess 2126 of the boss 2125 and is restrained from rotation by the recess 2126, a twist lock nut 2122 is threadedly secured to the lower end of the shaft of the twist lock 2121, and a cotter pin 2124 is passed through a through hole in the lower end of the shaft of the twist lock 2121 to prevent the twist lock nut 2122 from being loosened, and a washer 2123 may be interposed between the twist lock nut 2122 and the frame 21. The locking assembly 212 of the above embodiment rotates the rotational lock 2121 by 90 ° during the locking installation process, so that the rotational lock 2121 falls or seats into the groove 2126 of the boss 2125, thereby effectively preventing the rotational lock 2121 from rotating due to, for example, long-term vibration or external force during the use process; further, the locking nut 2122 is tightened and the cotter pin 2124 is installed, so that the cabin 11 can be easily locked to the frame 21. Therefore, the locking assembly 212 of the above embodiment is convenient in locking operation and good in locking reliability.

Specifically, when the hull 11 of the rail field work system 10 needs to be locked and mounted on the rail work vehicle 20, the upper end of the rotational lock 2121 is lifted and rotated 90 degrees, then the rotational lock 2121 is pressed against the bottom step on the inner side of the box corner 118 of the hull 11, and at the same time the rotational lock 2121 falls into the groove of the grooved boss 2125, the rotational lock nut 2122 is further tightened, and then the cotter pin 2124 is mounted to prevent the threads from loosening; after the locking assemblies 212 complete the operation of locking the cabin 11 to the rail working vehicle 20; when the cabin 11 needs to be detached from the rail operating vehicle 20, the cotter 2124 can be sequentially detached, the twist lock nut 2122 can be unscrewed, and the twist lock 2122 can be lifted and reversely rotated by 90 degrees, at this time, the twist lock 2122 is parallel to the bottom opening of the box corner 118 of the cabin 11, so that the detachment operation can be conveniently realized. The whole locking, mounting and dismounting process is simple and easy to operate.

As further shown in fig. 1-4, in one embodiment, each wheel of the corresponding wheel pair is further provided with a respective brake assembly 235, and brake assembly 235 may be implemented by a pneumatic brake cylinder or the like, the electrical power required by the pneumatic brake cylinder, e.g., an air compressor, also being provided by generator set 12.

It should be noted that the traction motor 221 can adapt to external force and rotate reversely at a low speed, so that the gear shifting design of the axle gear box 227 required by hydraulic transmission or hydraulic transmission when being coupled can be avoided, that is, the axle gear box 227 can be further designed into an axle gear box without a gear shifting mechanism or a gear shifting mechanism; the gearbox without the gear shifting mechanism can also avoid the safety risk that hydraulic transmission or hydraulic transmission forgets to put in neutral gear and can cause the hydraulic motor to reversely rotate and damage.

As a comparison for understanding the above embodiments, in the case that the conventional hydraulic drive is operated by using a hydraulic motor (e.g. a dedicated diesel engine) as power to drive the axle gear box to transmit the power to the axle and the wheels, the internal structure of the hydraulic motor limits the motor from being able to rotate reversely under the action of external force, so that the hydraulic motor is easily damaged if the transmission linkage is dragged to generate reverse rotation. Therefore, in the prior art, if the vehicle is dragged by the hitch, the hydraulic motor and the axle gear box must be disengaged, i.e., a neutral operation is performed, so that the motor does not passively reverse when the wheels and the axle rotate. The prior art neutral operation further necessitates the prior axle gear box to have a gear shifting mechanism (e.g., a torque converter), which is very complicated in construction and is subject to failure, in which case the hydraulic motor is driven in reverse rotation and damaged in the event of a failed gear disengagement.

The axle gearbox 227 without a shifting mechanism may specifically, but not exclusively, employ a two-stage crossed-axis gear drive, e.g., a first stage of a cylindrical gear pair, a second stage of a helical bevel gear pair; the axle gearbox 227 may illustratively include a housing, gear pairs, bearing pairs, sealing systems, lubrication systems, and the like.

In an embodiment, the traction motor 221 may be a motor capable of rotating in a reverse direction by applying an external force and having a stepless speed change function, for example, a variable frequency dc or ac motor.

In one embodiment, leaf springs may be provided between the frame 21 and the bogie of the rail working vehicle 20, which leaf springs may act as a shock absorbing mechanism. The axle box of the common railway bogie is bigger, and a group of springs (for example, consisting of 2 springs) can be arranged and positioned on the axle box through a more complex structure; however, the bogie having the two-axle structure according to the embodiment of the present invention has insufficient strength because the axle box is small, 2 springs are not sufficiently arranged, and the springs are easily eccentric. In consideration of these factors, this embodiment selects a plate spring that is better suited to a two-axle bogie structure having a small axle box and a small installation space, and that has a sufficient strength.

As shown in fig. 1 to 4, the front end and the rear end of the frame 21 are respectively provided with different types of

couplers

25a and 25b, so that when the rail vehicle 20 loses power and cannot leave the site due to failure of the generator set 12, for example, the rail vehicle 20 can be added with a vehicle coupling function by the couplers, and the rail vehicle 20 can be pulled to leave the site by coupling the rail vehicle 20 with a rescue rail vehicle through the

couplers

25a or 25 b.

In one embodiment, as shown in fig. 7 and 9, the coupler 25b near the end of the working site is configured as a tow hook 25b without a decoupling device having a lower height, for example, the upper end surface of the tow hook 25b is lower than the height of the undercarriage of the cabin 11. In this way, when the crane 16 carries the normalizing machine 30, the tow hook 25b does not collide with the normalizing machine 30, and the tow hook 25b does not interfere with or affect the carrying operation.

As further shown in fig. 1 to 4, the rail working vehicle 20 may be provided with a running light 216 and/or a plurality of position lights 219, wherein the running light 216 is exemplarily provided on the front end surface and the rear end surface of the frame 11, and the plurality of position lights 219 are provided on the side surfaces of the frame 11. The running lights 216 improve the running conditions of the rail vehicle 20 in, for example, a tunnel, and the position indicator lights 219 can provide safety warnings for field operators when the rail vehicle 20 runs at a low speed.

As further shown in fig. 1-4, rail working vehicle 20 further includes cab 24, cab 24 being fixedly disposed at the head or tail of frame 21, such as at the head. The cab 24 may be surrounded by a corresponding housing, and an operation console 2147 may be disposed inside the cab 21, and for facilitating operation and control by an operator, the operation console 2147 may be provided with a running push rod 2141, a brake push rod 2142, a display part 2143 (e.g., a display screen), a speed meter 2144, a wind pressure meter 2145, and the like.

When the rail working vehicle 20 is driven to carry the rail working system 10 to the site or leave the site, the operator performs operation control on the operation table 2147 of the cab 24, for example, operates the operation push rod 2141 to advance or retreat at a low speed to the site working point, and pushes the brake push rod 2142 to stop the rail working vehicle 20 at the site working point. The rail field work system 10 may then be operated to perform field work preparation and operations, such as post-rail welding normalizing; after completion of the field work, the operator may pull back the brake pushrod 2142 to cancel the braking, drive the run pushrod 2141 forward or backward at a low speed to the next field work point.

In one embodiment, in order to overcome the problem that the cab 24 installed at one end cannot conveniently observe the road condition observed at the other end (for example, the operator in the cab 24 at the head cannot observe the road condition at one end at the tail because of being blocked by the bulky rail field operation system 10 carried by the operator), an image sensor 27 (for example, a camera) is arranged at the tail of the frame 21 of the rail working vehicle 20, the image sensor 27 is coupled with the display part 2143 of the cab 24, when the rail working vehicle 20 runs towards the tail direction (for example, the x direction positive direction) of the frame 21, the image sensor 27 collects the image information of the road condition ahead in real time, and the image collected by the image sensor 27 is transmitted to the display part 2143 for display; thus, the operator in the cab 24 can observe the information of the road condition ahead in real time through the image sensor 27, so that the driving safety of the working vehicle is ensured, the two-way driving can be realized without turning, the driving flexibility of the steel rail working vehicle 20 is improved, and the working efficiency is improved.

It should be understood that the image sensor 27 is disposed at an end opposite the cab 24, for example, when the cab 24 is fixedly disposed at the rear of the frame 21, the image sensor 27 may be disposed at the head end of the frame 21.

The rail site normalizing operation system 10 and the rail site operation assembly 1000 according to the embodiment of the invention are further described in detail by way of example in conjunction with fig. 7 to 17. In the embodiment shown in fig. 7-9, the rail site work assembly 1000 includes the rail work vehicle 20 of any of the above embodiments, and further includes the rail site normalizing work system 10 carried by the rail work vehicle 20. The steel rail field operation assembly 1000 can respectively provide power for the steel rail field normalizing operation system 10 and the steel rail operation vehicle 20 through a set of generator set 12, so that the steel rail operation vehicle 20 can be driven to move on a steel rail by providing power for the generator set 12 when carrying the steel rail field normalizing operation system 10, self-power walking is realized, electric energy required by field operation can be provided for the steel rail field normalizing operation system 10 through the generator set 12 during field operation, and the steel rail field operation assembly is very suitable for on-line or off-line field operation.

In one embodiment, as shown in fig. 7-15, the rail site normalizing operation system 10 has a substantially box-structured enclosure 11, such as a container-structured enclosure, to facilitate overall handling as a container. The cabin 11 may be formed by welding steel materials, and has a large inner space for installing various devices required for performing a field normalizing operation, and the base frame of the cabin 11 is used for carrying the devices, and has certain strength and rigidity, and may be formed by welding sectional materials and steel plates. To facilitate the removable mounting and locking of the rail field normalizing operation system 10 as a whole to the frame 21, a plurality of container corners 118 are welded to the hull 11 corresponding to each locking assembly 212 on the frame 21.

The cabin 11 may be provided with a partition 119 therein as shown in fig. 14, so that the interior of the cabin may be generally divided into an equipment room relatively far from the site operation point (e.g., an interior space near the front end) and a working room relatively near the site operation point (e.g., an interior space near the rear end). More spaces may be provided in the interior to divide the cabin 11 into more relatively independent spaces according to specific needs.

Referring to fig. 11 to 14, the cabin 11 is provided with a lighting window, for example, a lighting window 1131 (as shown in fig. 11) disposed on a side surface of the cabin 11, a lighting window 1132 (as shown in fig. 13) disposed on the hatch 119 at the tail end of the cabin 11, and a lighting window 1133 (as shown in fig. 14) disposed on the partition 119 of the cabin 11; the cabin 11 may further be provided with a plurality of passing hatches for operator to enter and exit, for example, one or more passing hatches 1141 (as shown in fig. 11) disposed on the side of the cabin 11, a passing hatch 1142 (as shown in fig. 12) disposed at the front end of the cabin 11 to facilitate the operator's cab 24 to enter from the cabin 11, and a passing hatch 1143 (i.e., an access door, as shown in fig. 14) disposed on the partition 119 of the cabin 11; the enclosure 11 may also be provided with a plurality of louvers for facilitating ventilation, such as a louver 1151 (shown in FIG. 11) disposed on a side of the enclosure 11, a louver 1152 (shown in FIG. 12) disposed at a front end of the enclosure 11, and a louver 1153 (shown in FIG. 14) disposed at the compartment 119 of the enclosure 11.

Continuing with FIG. 7, a variety of equipment (shown in phantom in FIG. 7) may be disposed within the nacelle 11 as may be required to accomplish the on-site normalizing heat treatment, such as one or more of a generator set 12 (including, for example, a diesel engine), a normalizing machine 30, an electrical control cabinet 14, a cooling unit 15, a crane 16, a hydraulic power unit 17, a normalizing management system 18, a blast apparatus 19, an exhaust gas purification apparatus 13, and the like. The size of the nacelle 11 may be designed based on the particular dimensions of the rail car 20, the number and size of the equipment it houses, etc.

The normalizing machine 30 performs the normalizing process by electromagnetic induction heating of the welding head of the steel rail through the electromagnetic coil, so that the generator set 12 is required to generate power on site to provide the power required by the induction heating. Of course, the generator set 12 can also provide other devices or equipment (e.g., hydraulic power unit 17, etc.) in the nacelle 11 with the power required for its operation. In particular, the genset 12 may be a diesel genset, and thus, may be configured with a corresponding diesel engine, accordingly. Corresponding to the cooling requirements of the devices such as the generator set 12 and the like, the cooling unit 15 can be correspondingly configured and used for cooling and radiating the generator set 12, the induction coil and the like in operation.

Wherein, the crane 16 is used for carrying the normalizing machine 30, for example, when the field normalizing treatment is started, the crane 16 can hoist the normalizing machine 30 in the cabin body 11 to the steel rail outside the cabin body 11, even accurately hoist the normalizing machine to the position of the welding joint to be subjected to the heat treatment; after the normalizing process is completed, the normalizing machine 30 may be lifted back into the tank body 11.

Wherein the hydraulic lines of the hydraulic pump station 17 can be connected with the hydraulic lines of the normalizing machine 30, so as to provide hydraulic pressure required for at least the action of the internal components (such as coil opening and closing and translation devices) of the normalizing machine 30. It will be appreciated that the hydraulic power unit 17 may also provide hydraulic power to other hydraulically powered devices (e.g., rams) such as the crane 16, the main deck door opener 117, etc. in the rail field normalizing operation system 10.

The normalizing management system 18 is used for managing the heat treatment process of the normalizing machine 30 and storing corresponding normalizing processing data, and can be realized by a computer device with a human-computer interaction interface.

The air injection device 19 is used for injecting air to the surface of the welding joint after normalizing treatment is performed on the welding joint, so that the surface hardness of the welding joint can be recovered. As an example, the air blowing device 19 is provided with an air compressor or the like to generate compressed air, and the compressed air is rapidly blown against the weld joint surface of the rail 90 by a plurality of air blowing nozzles (not shown) provided in the induction coil device 37.

The front end of the rail on-site normalizing operation system 10 may further be provided with a cooling fan, for example, the cooling fan may be a cooling fan on a diesel engine or a cooling fan of a water chiller, and the cooling fan may take away a large amount of heat generated in the direction in which the normalizing machine 30 is located, even the heat generated inside the rail on-site normalizing operation system 10 in another direction in an airflow manner (for example, the airflow flows from the tail end to the front end), that is, the air inlet corresponds to the main cabin door 116, and the air outlet corresponds to the front end of the rail on-site normalizing operation system 10, so that overheating at an on-site operation point and due to electromagnetic induction heating may be avoided. Specifically, the airflow may flow through the process chamber, louvers 1153 of compartment 119, equipment chamber, and louvers 1152 in sequence, and may also carry away a significant amount of heat generated in the generator set 12 in the equipment chamber, which may be beneficial in improving the field process environment.

The exhaust gas purification device 13 is disposed corresponding to an exhaust port of the diesel engine, and has an exhaust gas purification function, which is particularly advantageous for improving a working environment of a field operation in, for example, a tunnel. Further optionally, a silencing assembly which is beneficial to noise reduction, such as silencing cotton and a silencer, can be additionally arranged in the cavity of the smoke exhaust pipeline of the diesel engine, so that the working environment of field operation is further improved, the health of operators is protected, and noise pollution is reduced.

Continuing with fig. 7, the normalizing machine 30, the crane 16, the hydraulic power unit 17, and the like are disposed in the work room, and the generator set 12 (including, for example, a diesel engine), the electrical control cabinet 14, the cooling unit 15, the normalizing management system 18, the air blowing device 19, the radiator fan, the exhaust gas purification device 13, the muffler assembly, and the like are disposed in the equipment room.

As further shown in fig. 10, the generator set 12 may be a diesel generator set, which includes a diesel engine 121, a generator 123, and an integrated base 129 (i.e., a common base) having an inner cavity, wherein the base 129 is shared by and provides a common mounting reference for the diesel engine 121 and the generator 123, and the inner cavity of the base 129 is used for containing fuel of the diesel engine 121, that is, a diesel tank of the diesel engine 121 is implemented by the base 129, so that the structural layout of the generator set 12 is more compact and is very suitable for a small-space equipment room. Specifically, elastic shock absorbing pads 125 are respectively arranged between the diesel engine 121, the generator 123 and the base 129.

Specifically, the rear end of the cabin 11 may be provided with a work illumination lamp 1101 arranged at an end (e.g. the tail end) of the cabin 11 close to the site work point, which may be used to provide illumination during the site work, improving the work conditions, e.g. in a tunnel.

Specifically, the rear end of the cabin 11 is provided with a main door 116, i.e. a rear door, and the corresponding main door 116 may be provided with an opening and closing device 117 for driving the main door 116 to act correspondingly, and the opening and closing device 117 may be driven to act by hydraulic pressure provided by the hydraulic pump station 17. The upper end of the main cabin door 116 is hinged to the cabin body 11; when the main door 116 is opened, the opening and closing device 117 can push the main door 116 to rotate around the upper end thereof, so that the main door 116 is opened, and the crane 16 can conveniently carry the lighter 30; conversely, the primary hatch 116 may be closed.

In order to facilitate the handling of the lighter 30, a corresponding auxiliary control panel 109 may be disposed at a lower position of at least one side of the outer side of the cabin 11 corresponding to the operation room, the auxiliary control panel 109 may be disposed with corresponding function buttons, the function buttons may correspond to buttons for controlling some operations of the crane 16, buttons for controlling some operations of the opening and closing device 117, and the like, and an operator may also conveniently control the opening and closing device 117 to control the opening and closing of the main cabin door 116, may also conveniently control some operations of the crane 16, and may even conveniently control the operation illumination lamp 1101 by operating the auxiliary control panel 109.

In one embodiment, the main deck door 116 of the deck 11 is located at the end of the working chamber and can be easily opened or closed by the opening and closing device 117 when the rail working vehicle 20 is parked to be used for on-site work. The opening and closing device 117 is used for driving the main door 116 to act (for example, "open" or "close"); after the main deck door 116 is opened, the crane 16 can lift and move the normalizing machine 30, so as to conveniently and accurately move the normalizing machine 30 from the cabin 11 to a field operation point (for example, to align with a station of a welding joint); after the normalizing process is completed, for example, the crane 16 may lift and move the normalizing machine 30, so as to move the normalizing machine 30 from the field operation point to the cabin 11, and then close the main hatch 116.

In one embodiment, as shown in fig. 15, opening and closing device 117 mainly includes hydraulic cylinder 1171, link 1172, guide rod 1173, and outer end 1174 of piston rod 1175 corresponding to hydraulic cylinder 1171 (i.e., outer end 1174 of piston rod 1175); wherein, for example, guide rod 1173 can be substantially horizontally affixed to a side wall of nacelle 11, e.g., guide rod 1173 is substantially horizontally affixed to a side wall of nacelle 11, and hydraulic ram 1171 is also disposed substantially parallel to guide rod 1173; the cylinder portion of hydraulic ram 1171 may be hinged to guide rod 1173 such that the cylinder portion is supported and allowed to rotate slightly relative to guide rod 1173 as piston rod 1175 moves in the direction of guide rod 1173, avoiding excessive piston wear and/or deformation of the cylinder portion, piston rod 1175. Both ends of the connecting rod 1172 are respectively hinged on the outer end 1174 and the main compartment door 116, and the outer end 1174 of the piston rod 1175 of the hydraulic oil cylinder 1171 is provided with or realized by a guide block which is sleeved on the guide rod 1173 and can slide back and forth along the guide rod 1173 in the horizontal direction; specifically, the guide block may be split relative to the piston rod 1175, e.g., secured to the outer end 1174 by a removable bolted connection, and the guide block may be integral with the piston rod 1175; when hydraulic cylinder 1171 drives piston rod 1175 to move, outer end 1174 slides on guide rod 1173 along horizontal direction, so that piston rod 1175 of hydraulic cylinder 1171 can keep horizontal telescopic movement, and then outer end 1174 transmits acting force of hydraulic cylinder 1171 to main compartment door 116 through connecting rod 1172, so as to conveniently complete opening and closing of main compartment door 116 of cabin 11. For example, when hydraulic ram 1171 pushes outer end 1174 of piston rod 1175 to the rearmost position as shown in fig. 15, main hatch 116 may be fully opened, greatly facilitating operation of crane 16; also, hydraulic ram 1171 may control the outer end 1174 of piston rod 1175 to remain in this position to continuously maintain main hatch 116 in a fully open state.

The opening and closing device 117 of the above embodiment can be disposed on the side wall of the cabin 11, and is compact and small in size, and the opening and closing device 117 has a simple structure and a reasonable installation position. It occupies a small space and does not substantially affect the working space of the crane 16.

In one embodiment, as shown in fig. 17, in order to better satisfy the on-line or off-line on-site rail normalizing operation of the railway line under different environmental conditions, the crane 16 disposed in the operating room may be specifically selected as a single-boom crane, and the front end of the boom of the single-boom crane 16 is connected to a rotatable hanger 361 (shown in fig. 18) of the normalizing machine 30 through a flexible chain (not shown), and the normalizing machine 30 can be lifted under the action of corresponding cylinders of the crane 16. The single-arm crane 16 is more suitable for single-arm hoisting of the normalizing machine 30 than, for example, a double-arm design. This is because, when the normalizing operation object is a non-linear rail, for example, the rail field operation assembly 1000 on the rail may be inclined due to the inconsistent height of the left and right rails of the rail at the bend, the z direction indicated in the drawing will not coincide with the gravity direction, when the crane lifts the normalizing machine 30, the flexible chain is in the gravity direction and may form a certain included angle with the z direction, if the distance between the booms of the double-boom crane is too small, the included angle will cause the flexible chain of the lifting normalizing machine 30 to interfere with and collide with one of the two booms of the crane, which is very unfavorable for the retraction and release of the normalizing machine 30, is also unfavorable for the precise alignment of the normalizing machine 30 relative to the welding joint station, and simultaneously, the service life of the flexible chain is also shortened; and also limits the y-direction range of motion of the two-armed crane within the main deck door 116 if the separation between the arms is too large. Therefore, the single-arm crane 16 occupies a small space in the y direction, the swing range of the arm body in the main cabin door 116 is larger, and the working range of the crane 16 is also larger; moreover, the single-boom crane 16 can be better suitable for the field operation of the rail at the bend, not only can the operation range be enlarged, but also the flexibility and the convenience of the field operation are improved, and the adaptability of the rail field normalizing operation system to different operation environments is further improved.

In one embodiment, continuing with fig. 17, the single-boom crane 16 may further optionally be a luffing, telescopic, slewing single-boom crane 16, the single-boom crane 16 comprising a slewing device 163, a luffing cylinder 161, a telescopic cylinder 162, a base boom 164, a telescopic boom 165, a mast 166, a base 167, and the like. The base 167 is fixed on the sliding plate 112; the turning device 163 has a hydraulic turbine that can drive the column 166 to turn in a predetermined angular range of the xy plane by way of gear transmission; upright 166 is the primary load-bearing structure with a gear face on the side of its lower end for engagement with the pinion of swivel 163; one end of the luffing cylinder 161 is hinged to the lower end of the upright 166, and the other end (corresponding to the piston end) is hinged to the basic arm 164 through a piston rod, so that a movable triangular structure is formed among the upright 166, the basic arm 164 and the luffing cylinder 161, and the lifting amplitude variation function can be realized through the piston action of the luffing cylinder 161; the telescopic arm 165 is extendable and retractable in the longitudinal direction thereof with respect to the base arm 164, and specifically, is driven to perform an extending and retracting action with respect to the base arm 164 by the extension and retraction cylinder 162 provided in the longitudinal direction thereof, so that the telescopic arm 165 and the base arm 164 together form an extendable and retractable arm body. The front end of the telescopic arm 165 is connected to a rotatable spreader 361 (shown in fig. 18) of the normalizing machine 30 by a flexible chain (not shown).

Specifically, when the normalizing operation is carried out, the luffing cylinder 161 of the single-arm crane 16 extends out, the normalizing machine 30 is lifted away from the bottom plate of the cabin body 11, the telescopic cylinder 162 of the single-arm crane 16 extends out, and the telescopic arm 165 extends, so that the normalizing machine 30 extends out of the cabin body 11, and then the luffing cylinder 161 retracts, so that the normalizing machine 30 descends until the normalizing machine 30 reaches the corresponding steel rail joint normalizing station; conversely, the single-arm crane 16 may move the normalizing machine 30 from the normalizing station to the floor of the nacelle 11. In the above operation, the suspended normalizing machine 30 can be rotated by using the rotating device 163 as necessary.

In an embodiment, continuing with fig. 17, in view of the fact that the range of rotation angle and the extension and retraction distance of the crane 16 are easily limited by the width of the main hatch 116 and the length of the working chamber, in order to increase the field normalizing working range, a corresponding skid 110 is further provided for the crane 16 on the undercarriage of the nacelle 11, for example, on the undercarriage of the working chamber near the field working point. The crane 16 is integrally installed on the sliding mechanism 110, and by moving the sliding mechanism 110 relative to the underframe of the cabin 11 in the x direction, the boom of the crane 16 can be extended out of the cabin 11 for a longer time, the upright post 166 is closer to the main cabin door 116, and the angle of rotary operation becomes larger, so that the field normalizing operation range is effectively enlarged, the operation of the steel rail field normalizing operation system in narrow spaces such as tunnels is facilitated, and the adaptability of the steel rail field normalizing operation system to different operation environments is improved; moreover, the flexibility of the operation can be greatly improved. Skid mechanism 110 may be implemented in the form of a skid platform upon which crane 16 may be carried substantially entirely. Specifically, the sliding mechanism 110 may include a sliding guide groove 111, a sliding plate 112, a vertical rolling bearing 113 mounted on the sliding plate 112, a horizontal rolling bearing 114 mounted on the sliding plate 112, a sliding cylinder 115, and the like. Wherein, the upright 166 of the single-arm crane 16 can be fixed on the sliding flat plate 112 by bolt installation; the sliding guide groove 111 is arranged in or on the underframe of the cabin 11 approximately along the x direction, and has a groove that is concave in the left-right direction, and the groove is surrounded by three surfaces, namely an upper groove wall, an inner groove wall and a lower groove wall; the sliding oil cylinder 115 is arranged in the bottom frame of the cabin body 11, a piston rod of the sliding oil cylinder can act on one end face of the sliding flat plate 112, and the sliding oil cylinder 115 can push the sliding flat plate 112 to move back and forth along the sliding guide groove 111 in the x direction, so that the operation range is expanded; a plurality of rolling bearings, for example, four vertical rolling bearings 113 and four horizontal rolling bearings 114 are mounted on the sliding flat plate 112; two of the four vertical rolling bearings 113 are respectively installed on two side surfaces of the sliding flat plate 112 as a group, and the vertical rolling bearings 113 can roll along the upper groove wall or the lower groove wall of the sliding guide groove 111 and are limited by the upper groove wall and the lower groove wall of the sliding guide groove 111 in the z direction; two of the four transverse rolling bearings 114 are respectively installed on two side surfaces of the sliding flat plate 112 as a group, and the transverse rolling bearings 114 can roll along the inner groove wall of the sliding guide groove 111 and are limited by the inner groove wall of the sliding guide groove 111 in the y direction.

Alternatively, as shown in fig. 17, in the front-rear direction of the sliding plate 112, the horizontal rolling bearing 114 is installed near the inner end with respect to the vertical rolling bearing 113, that is, the vertical rolling bearing 113 is installed near the outer end with respect to the horizontal rolling bearing 114; for example, for one side surface of the sliding flat plate 112, two vertical rolling bearings 113 are respectively installed closer to the front end and the rear end of the sliding flat plate 112, and two horizontal rolling bearings 114 are respectively installed closer to the middle position of the sliding flat plate 112; thus, the vertical limiting function of the vertical rolling bearing 113 can be exerted, and the front and rear lever acting force generated when the arm body of the crane 16 extends outwards can be resisted better.

When normalizing operation is carried out, the normalizing machine 30 is lifted away from the bottom plate of the cabin body 11 by the single-arm crane 16, the sliding oil cylinder 115 is operated, the sliding flat plate 112 is moved to a preset position in the x direction and is locked, in the moving process, considering that the weight of the lifted normalizing machine 30 is large, the centers of the crane 16 and the normalizing machine 30 are deviated to the x direction, the pair of vertical rolling bearings 113 close to the field operation direction are pressed down on the lower groove wall of the sliding guide groove 111 and roll along the lower groove wall, and the pair of vertical rolling bearings 113 far away from the field operation direction are pressed down on the upper groove wall of the sliding guide groove 111 and roll along the upper groove wall, so that the sliding flat plate 112 can be prevented from swinging in an xz plane in the sliding process; at the same time, the transverse rolling bearing 114, which is retained in the y-direction by the inner groove wall of the sliding guide groove 111, can prevent the sliding plate 112 from swinging in the xy-plane (even if the sliding plate 112 carries a very heavy crane 16). Thus, the slip plane 112 and the crane 16 carried thereby have good linearity of movement in the x direction, avoiding excessive up and down and/or side to side swinging. Moreover, the method can be realized through 8 bearings, and the cost is low.

It will be understood that the vertical rolling bearings 113 and the lateral rolling bearings 114 are not limited to four, and for example, 6 or more vertical rolling bearings 113 and lateral rolling bearings 114 may be arranged as needed.

It will be understood that the particular implementation of the sliding mechanism 110 is not limited to the above embodiment, for example, in another variant, the sliding plate 112 may be made into a groove with two sides folded inwards to form a sliding guide slot, and a bearing is fixedly installed and positioned in the groove, and the sliding plate 112 can slide back and forth on the chassis through the bearing. In another alternative, the rolling bearings may be disposed on both sides of the bottom frame, but more rolling bearings may be installed to meet the requirement of the crane, and accordingly, no bearing may be installed on the sliding plate 112.

A normalizing machine 30 according to an embodiment of the present invention, which can be disposed in the cabin 11 of the rail site normalizing operation system 10 according to an embodiment of the present invention, is further illustrated in detail with reference to fig. 18 to 31. It will be appreciated that the rail field apparatus included in the rail field normalizing operation system 10 is not limited to the normalizing machine 30 of the following exemplary construction or type.

For convenience of explanation, the x-direction, y-direction and z-direction are defined in fig. 18 to 31, respectively, wherein the high direction of the normalizing machine is defined as z-direction, the direction of the steel rail is defined as x-direction, and the y-direction is perpendicular to the x-direction and the z-direction; for the sake of clarity, the positive direction of the x direction is directed to the rear/tail end of the normalizing machine, and the positive direction of the y direction is directed to the right side of the normalizing machine. Also, in the following description with respect to fig. 18 to 31, the azimuthal terms such as "front/head" and "rear/tail" are defined with respect to the x direction, the azimuthal terms such as "left" and "right" are defined with respect to the y direction, and the azimuthal terms such as "up" and "down" are defined with respect to the z direction. It is to be understood that the definitions of these directions are for the description and clarification of the relative positions, which may vary accordingly depending on the orientation of the normalizing machine, etc.

As shown in fig. 18 and 19, the normalizing machine 30 may perform an inline or an offline normalizing process on a welded joint (not shown) on, for example, a rail 90; it will be appreciated that the welding method employed to normalize the object, i.e., the weld joint on the rail 90, is not limiting, however, the weld joint on the rail 90 generally has significant internal stresses in the weld and may be released during normalizing in general, nor is the normalization process specifically employed limited to embodiments of the present invention. The normalizing machine 30 mainly includes a clamping and centering device 31 and an open-close type induction coil device 37, and may further include a coil opening-closing and translating device 32, and may further include one or more of a transformer 33, an alignment operating part 391, a housing 39, a hanger 36, an infrared thermometer 38, an image sensor 35, and the like. Wherein the above or other devices or components of the normalizing machine 30 may be directly or indirectly coupled with respect to the hanger 36 so as to be integrally carried by the hanger 36; the infrared thermometer 38 is used for monitoring corresponding temperature information; the housing 39 may be formed from sheet steel and substantially encloses the various devices or components within it, thereby forming the normalizing engine 30 in a generally, for example, box-like shape, facilitating overall handling.

Specifically, as shown in fig. 20 to 23, the hanger 36 may be formed by rigidly coupling high-strength steel structures (for example, by welding steel profiles), which may form a large internal space to accommodate various devices or components of the normalizing machine 30, such as the open-close type induction coil device 37, the coil opening/closing and translating device 32, the transformer 33, and the like, and is beneficial to improving the overall structural compactness of the normalizing machine 30. In an embodiment, hanger 36 includes a square frame body 368 and a frustum-shaped frame body 369 disposed above square frame body 368, the frustum-shaped frame body 369 is provided with a frustum 3691 at the top, which may be used for mounting rotatable hanger 361, and hanger 361 is fixedly mounted on frustum 3691 by two parallel pins 363, for example. The crane 16 may be connected to the rotatable sling 361 by a flexible chain tension member (e.g., a flexible chain), so that when the normalizing machine 30 is lifted, particularly when performing an alignment operation on a welded joint to be normalized, the operator may manually push the lifted normalizing machine 30 to rotate to a predetermined orientation (by utilizing the rotatable nature of the rotatable sling 361), and the operation is more convenient.

The square frame body 368 may be a square table frame structure, and may be formed by fixedly coupling a plurality of rigid beams, as illustrated in fig. 20, the rigid beams include two beams located at the top of the square frame body 368 and arranged in parallel in the x direction, four beams arranged in parallel in the y direction (where two beams are arranged in a group on the square frame body 368 and are arranged in front and at the back respectively as one group), and four beams arranged in parallel in the z direction (where two beams are arranged in a group on the square frame body 368 and are arranged in front and at the back respectively as one group); corresponding bearing parts can be fixedly arranged on the rigid beams arranged in the x direction to fix internal components (such as the pressure device 33, the infrared thermometer 38 and the like) of the normalizing machine 30; the size of the frame body 368 can be adjusted by the size of the components contained in the frame body 368. In one embodiment, as shown in fig. 20 to 25, the clamp centering device 31 includes a rigid holder 301 and a pair of clamp arms 311 mounted on the rigid holder 301, and the pair of clamp arms 311 includes a front pair of clamp arms 311a and a rear pair of clamp arms 311b, which are arranged substantially in parallel in the front and rear direction. The front clamp arm pair 311a and the rear clamp arm pair 311b are rotatably mounted on the rigid holder 301 in the front-rear direction, respectively, and the front clamp arm pair 311a and the rear clamp arm pair 311b are restricted from being displaced in the front-rear direction by the rigid holder 301; thus, the front clamp arm pair 311a and the rear clamp arm pair 311b can be easily rotated in the yz plane on the rigid retainer 301 to clamp the rail 90 or release the rail 90, and the rigid retainer 301 can resist or bear the internal stress released during the normalizing process, so that the clamped rail 90 is not easily deformed during the normalizing process. The front pair of clamping arms 311a may be arranged symmetrically left and right with respect to the central plane 310 of the clamp centering device 31, and the rear pair of clamping arms 311b may be arranged symmetrically left and right with respect to the central plane 310 of the clamp centering device 31, which facilitates simultaneous clamping and centering of the front pair of clamping arms 311a and the rear pair of clamping arms 311b with respect to the rail 90.

As shown in fig. 19, 22 and 23, the rigid retainer 301 may form a substantially closed frame enclosing a cavity and be located substantially below the hanger 36, and specifically, a square (e.g., rectangular) frame structure formed by fixedly coupling a front clamp arm fixing cross beam 314a, a rear clamp arm fixing cross beam 314b, a left cross beam coupling shaft 315a and a right cross beam coupling shaft 315b, thereby forming the rigid retainer 301 according to an embodiment of the present invention; specifically, both ends of the left and right

beam coupling shafts

315a and 315b are threaded, and the threads at both ends may partially protrude outside the front and rear clamp

arm fixing beams

314a and 314b, respectively, and achieve fixed coupling by means of, for example, a slotted nut 3151, respectively. The front clamp arm fixing cross member 314a or the rear clamp arm fixing cross member 314b may be formed of, for example, a front steel plate and a rear steel plate with a stopper hole 3142 formed therebetween, and the arms of the clamp arm pair 311 may pass through the stopper hole 3142 and be stopped in the front-rear direction by the stopper hole 3142; specifically, each arm of the front clamp arm pair 311a is longitudinally retained in a retaining hole 3142 of the front clamp arm fixing cross member 314a and rotatably mounted on the front clamp arm fixing cross member 314a by a clamp arm rotating pin 3141, and each arm of the rear clamp arm pair 311b is longitudinally retained in a retaining hole 3142 of the rear clamp arm pair 311b and rotatably mounted on the rear clamp arm pair 311b by a clamp arm rotating pin 3141, whereby the front clamp arm pair 311a and the rear clamp arm pair 311b are rotatably mounted on the rigid holder 301 in the longitudinal direction, respectively.

The rigid retainer 301 may be a very stable frame structure, and during the normalizing process, the rigid retainer 301 may effectively resist or bear the internal stress released by the normalizing process of the weld joint, for example, the rigid retainer 301 may not deform even if it bears the internal stress released by a very large weld joint; therefore, it is possible to effectively prevent the clamped rail 90 from being deformed or the like due to the release of the internal stress of the normalized weld joint during the normalizing process. It will be appreciated that the characteristics of the components providing the rigid cage 301 may be selected based on the amount of internal stress that the rigid cage 301 needs to effectively resist or withstand, thereby ensuring its rigid strength.

As illustrated in fig. 24, the clamping and centering devices 31 may be arranged in left-right symmetry along the central plane 310 thereof; further, the clamp centering device 31 may also be symmetrically disposed fore-and-aft along a centerline between the front and rear clamp

arm securing beams

314a and 314b, and thus, it will be appreciated that the arrangement of the components of the front end of the clamp centering device 31 shown in fig. 24 is equally applicable to the corresponding components of the rear end.

As shown in fig. 20 to 24, a plurality of pin holes 362 (e.g., four pin holes 362) are provided on a lower end of the square frame body 368 of the hanger 36, the pin holes 362 may be used to fixedly couple the hanger 36 and the rigid holder 301 of the clamping and centering device 31, for example, the clamping arm rotating pin 3141 may pass through the pin holes 362 to couple the front clamping arm fixing beam 314a or the rear clamping arm fixing beam 314b of the clamping and centering device 31 and the hanger fixing 36. In this way, the clamp centering device 31 and the hanger 36 can form a strong and stable body structure. It will be understood that the manner of fixed coupling between the hanger 36 and the rigid retainer 301 is not limited to the above-described embodiment, and may also be fixedly coupled with the rigid retainer 301 by welding or the like, for example, and may even be integrally molded with the rigid retainer 301; the lower end of the square frame body 368 of the hanger 36 is not limited to being fixed to the inner side surface of the front clamp arm fixing beam 314a or the rear clamp arm fixing beam 314 b; the specific shape of the hanger 36 is also not limited to the shape illustrated in the figures, and in other embodiments, the hanger 36 may also be deformed into a general internal body configuration, e.g., without a spreader, in the event that the normalizing machine 30 as a whole does not need to be moved by crane.

It will be appreciated that after the clamp centering device 31 clamps the rail 90 forward and backward, the clamp centering device 31 or the rigid retainer 301 provided therein also enables the overall positioning of the normalizing machine 30 relative to the rail 90, and the hanger 36 fixedly coupled to the rigid retainer 301 is also integrally positioned therewith. The coil opening/closing and translating means 32 can perform a local positioning operation such as weld alignment on the basis of the overall positioning, and for example, the opening/closing type induction coil means 37 can move the induction coil means 37 parallel to the rail 90 in the front-rear direction of the welded joint during alignment of the weld of the welded joint.

It should be understood that the rigid retainer 301 formed by fixedly coupling the front clamp arm fixing beam 314a, the rear clamp arm fixing beam 314b, the left beam coupling shaft 315a and the right beam coupling shaft 315b together with the hanger 36 can enclose a large internal space, and the internal space can be used to arrange the coil opening and closing and translating device 32, the induction coil device 37 and the transformer 33, etc. with large size (i.e. the coil opening and closing and translating device 32, the induction coil device 37 and the transformer 33, etc. are arranged in the internal space), so that the whole internal structure layout is reasonable, the whole structure is compact, and the whole field carrying and transferring are convenient.

It should also be understood that the stable square frame structure not only makes the internal structure layout of the normalizing machine 30 reasonable and compact, but also has higher structural strength, and by adopting the structure as a carrier and a reference for carrying the normalizing machine 30, the deformation caused by the extrusion shortening or elongation of the welded joint of the steel rail 90 under a high-temperature state due to the release of the internal stress of the welded joint during normalizing can be avoided, thereby being beneficial to the improvement of the quality and performance of the welded joint after normalizing, and also being beneficial to the basic stable and consistent spacing of the induction coil 371 relative to the section profile of the steel rail 90 enveloped by the induction coil 371 during the normalizing process, and improving the normalizing effect.

Specifically, each arm of the clamp arm pair 311 (e.g., each arm of the front clamp arm pair 311a or the rear clamp arm pair 311 b) is pivotally mounted on the clamp arm securing beam 314 by a clamp arm pivot pin 3141, respectively, so that each arm can pivot about the clamp arm pivot pin 3141, respectively, during a clamping operation, e.g., under the urging of the clamp cylinder 312. Moreover, the clamping arm pairs 311 are arranged in bilateral symmetry with respect to the central plane 310 of the clamping and centering device 31, thereby facilitating synchronous clamping and centering therebetween; in the case where the rail 90 to be normalized is a rail having a symmetrical cross section, the centering clamps 313 provided at the lower ends of the arms of the clamp arm pair 311 may also be arranged in left-right symmetry with respect to the center plane 310 and have a symmetrical structure.

In one embodiment, as further shown in fig. 24 and 25, a clamp cylinder 312 is provided for each of the front and rear

clamp arm pairs

311a and 311b, the clamp cylinder 312 being disposed laterally between the upper ends of the arms of the front or rear

clamp arm pair

311a or 311b, for example, the cylinder portion and piston rod of the clamp cylinder 312 being hinged to the top ends of the two arms of the front or rear

clamp arm pair

311a or 311b, respectively, and the clamp cylinder 312 being disposed substantially parallel to the y-direction. The clamping cylinder 312 can drive the two arms of the clamping arm pair 311 to rotate around the clamping arm rotating pin 3141 respectively so as to enable the centering clamp 313 to clamp the steel rail 90; optionally, the plurality of clamping cylinders 312 are the same (for example, the same structure, the same type, and the same parameters), and by providing the control component of the plurality of clamping cylinders 312, it is possible to synchronously control the clamping cylinders 312 so as to clamp the steel rail 90 substantially synchronously, thereby facilitating to drive the plurality of sets of clamping arm pairs 311 in unison, and facilitating to improve the synchronism of the clamping actions.

Further, the normalizing machine 30 not only has a function of clamping the steel rail 90 to be normalized, but also has a function of centering the steel rail 90 in a self-adaptive manner with respect to steel rails 90 of different shapes; the clamping and centering device 31 can be used to perform the above-described functions, namely to clamp the rails 90 together in the front and rear positions of the welded joint and to center the rails in a manner that is adaptive to the clamped rails 90.

It should be noted that the above-mentioned centering function achieved by the clamping and centering device 31 of the normalizing machine 30 fully considers the requirement that the coils of the open-close induction coil device 37 served by it need to stably and uniformly envelop the rail 90, and the case that the clamped rail 90 is a welded integrated rail with a certain precision; centering the clamped rail 90 in a self-adaptive manner can position the entire normalizing machine 30 relative to the rail 90 to be normalized at present, and particularly can position the coil 3712 of the open-close type induction coil device 37 relative to the rail 90 through the centering, and further the open-close type induction coil device 37 can perform induction heating by taking the rail 90 to be normalized at present as a positioning reference, so that even if the clamped rail 90 is different in inclination degree, front and rear batches and the like, the cross-sectional profile spacing between the coil of the closed induction coil device 37 and the rail 90 can be kept consistent better; that is, the clamping and centering device 31 clamps the welded and integrally connected rail 90 with a certain precision and centers the rail 90 as a reference, thereby ensuring the centering and positioning precision of the normalizing machine 30 relative to the normalized rail 90 and finally ensuring the coil and rail contour spacing to be kept consistent. Such a clamping and centering manner may result in good normalizing treatment (e.g., uniform weld induction heating temperature, good and stable normalizing treatment of welded joints of different batches of rails 90).

It will be understood that the centring operation performed by the clamping and centring device 31 described above is a centring operation performed during clamping itself with respect to the rail 90, and not a centring operation performed on the rail 90 itself with respect to other objects or other rails, which is entirely different from the centring operation performed when welding two unconnected rails, for example. Regarding specific differences, for example, when steel rails are subjected to flash welding, the two steel rails at different positions are used as objects for clamping alignment, the requirement of clamping alignment is that the two steel rails are positioned on a straight line and aligned with each other, the welding machine is used for ensuring that the two steel rails are aligned with each other, and the sections of the two steel rails are completely aligned; and because of the requirement of the welding process, a certain upsetting force is applied to the two steel rails in the axial direction while clamping, and the welding joint can be ensured to meet the specified strength requirement; in addition, it is also desirable to facilitate adjustment of the axial position between the two rails. Therefore, when welding the rails, not only the clamping centering device is required to have high clamping force and upsetting force, but also the front and rear pairs of clamping devices must be movable relative to each other.

In one embodiment, the centering clamp 313 has an elastic support function against the contact surface of the rail 90 when clamping the rail 90, taking into account the specific differences of the rail 90 being normalized, for example, a slight left-right inclination of a curved section of rail, etc., wherein the elastic support function may be realized in particular by an elastic element or the like provided in the centering clamp 313. Illustratively, as shown in FIG. 27, a respective resilient support member may be provided in each clamp body 3134 of the centering clamp 313, the resilient support member being disposed relative to the railhead chin surface 913 of the rail 90, which may enable the clamp centering device 31 to adaptively center the clamped rail 90 along the centerline 919 of the rail 90.

It should be noted that the elastic supporting element in the elastic supporting assembly is located between the centering clamp 313 and the head lower jaw surface 913 of the steel rail 90, and the elastic element can be compressed during the clamping process to generate a rebound force to the centering clamp 313, and the rebound force can elastically support and slightly adjust the orientation of the clamping and centering device 31 relative to the steel rail 90, so as to achieve the accurate centering adaptive to the steel rail 90, and also facilitate the space between the induction coil 371 and the cross-sectional profile of the steel rail 90 enveloped by the induction coil 371 after being closed to be substantially constant during the normalizing process, and facilitate the space between the induction coil 371 and the cross-sectional profile of the steel rail 90 enveloped by the induction coil 371 to be substantially constant after being centered for multiple times, for example, to improve the normalizing effect.

Fig. 27 shows a partial schematic view of the centering clamp 313 according to an exemplary embodiment when it is used for clamping a rail 90. As shown in fig. 24 and 27, the clamping and centering device 31 further includes a positioning block 316, the positioning block 316 is fixedly mounted on the lower surface of the clamping arm fixing beam 314 so as to face the rail 90, and the positioning block 316 abuts against the rail head of the rail 90 when the rail 90 is clamped. The positioning block 316 can act together with the centering clamp 313 during the clamping and centering process to position the normalizing machine 30 relative to the clamped rail 90. In one embodiment, the positioning block 316 is detachably and fixedly mounted on the positioning base of the lower surface of the clamp arm fixing cross member 314, so that different positioning blocks 316 can be designed correspondingly and corresponding positioning blocks 316 can be selected for mounting corresponding to different types of rails 90. Correspondingly, the clamp body 3134 of the centering clamp 313 can be designed to be detachably fixedly connected to the arms of the clamping arm pair 311, for example by means of a screw 3137. Thus, clamp 3134 may also be designed for different types or models of rail 90, and the corresponding clamp 3134 may be selectively installed depending on the rail 90 to be clamped. Thus, the normalizing machine 30 can be adapted to and normalized for more rail types (e.g., "i" rails, channel rails).

Taking as an example that the contact surface of centering clamp 313 against rail 90 when clamping rail 90 includes railhead jaw face 913 and web side face 912, the resilient support assembly on clamp body 3134 of centering clamp 313, support 3131 (e.g., a steel ball) having an arcuate contact surface, and resilient element 3132; the left and right clamp bodies 3134 may be detachably fixed to the left and right arms of the pair of clamp arms 311 by bolts 3137, respectively, and positioning grooves 3135 opened toward the head jaw surface 913 of the rail 90 are opened in the clamp bodies 3134, for example, the opening direction of the positioning grooves 3135 is substantially perpendicular to the head jaw surface 913; the elastic element 3132 and the supporting body 3131 may be sequentially placed in the positioning groove 3135 from bottom to top, the positioning groove 3135 may be filled with a corresponding grease, and then the gap between the supporting body 3131 and the positioning groove 3135 may be covered by the cover plate 3133, and the cover plate 3133 may position the supporting body 3131 and the elastic element 3132 in the positioning groove 3135. The elastic element 3132 may be, in particular but not exclusively, a disc spring, and the support 3131 is intended to contact the rail 90, which may be made of various rigid materials; the shape of the clamping surface of clamp 3134 may be specifically designed according to the shape of web side 912 of rail 90 that it contacts.

For example, in the process that the clamping cylinder 312 drives the clamping arm pair 311 to clamp the rail 90, the clamp body 3134 is in rigid contact with the rail web side 912 of the rail 90 and rigidly clamps the rail web, the arc-shaped contact surface of the support 3131 in the centering clamp 313 is in contact with the railhead jaw surface 913 and forms elastic contact with the railhead jaw surface, the support 3131 of the elastic support assembly can apply pre-tightening force to the railhead jaw surface 913, as the pre-tightening force increases, the z-direction component of the pre-tightening force can push the railhead tread 911 of the rail 90 against the positioning block 316, the front clamping arm fixing cross beam 314a and the positioning block 316 of the rear clamping arm fixing cross beam 314b are pressed and positioned on the railhead tread 911 with the railhead tread 911 as a reference, that is, the clamping and centering device 31 can perform centering operation with the railhead tread 911 as a reference; at the same time, the resilient element 3132 (e.g. a disc spring) will be compressed and generate a force that may act on the clamp body 3134, which force (e.g. its y-direction component) may center along the centre line 919 of the rail 90, with reference to the rail head tread 911, causing the centering clamp 313 to center during clamping.

The introduction of the positioning block 316 and the support 3131 and the elastic element 3132 therefore makes it possible to automatically center the centering pincer 313 during the clamping process, in a manner that is adaptive to the conditions of, for example, the tread 911 of the rail head, irrespective of whether the device 30 for sensing the presence of an additional adjustment of the device for normalizing is to be made in response to, for example, a lateral inclination of the tread 911 of the rail 90 in the region of a bend, due to the bend; therefore, no matter the steel rail 90 is in a straight line section or a curve section, the centering clamp 313 can perform adaptive centering along the central line 919 of the clamped steel rail 90 basically in the clamping process, and meanwhile, the centering clamp is favorable for ensuring that the distance between the induction coil 371 of the induction coil device 37 and the cross-sectional profile of the steel rail 90 enveloped by the induction coil device to be kept stable and consistent basically, for example, when multiple times of normalizing are performed on a plurality of welding joints of the same steel rail 90, the centering effect is good by taking the same steel rail 90 as a reference, so that the induction coil 371 is stable and consistent relative to the steel rail 90 enveloped by the induction coil 371, and the uniformity of induction heating effect in the normalizing process or in the normalizing process for multiple times is improved.

It should be noted that, when the type or structure of the rail 90 acted on by the centering clamp 313 is changed, the corresponding structure of the centering clamp 313 may be changed correspondingly, for example, the shape of the clamp 3134, the orientation of the positioning groove 3135 on the clamp 3134, and the like. When normalizing the welding joints of the steel rails 90 with different types or structures, the corresponding positioning blocks 316 and the corresponding centering clamps 313 can be replaced and installed.

To further enhance the clamping synchronization of the centering clamp 313, a corresponding synchronization clamping assembly is provided for each clamping arm pair 311 for causing the left and right arms of the front clamping arm pair 311a or the rear clamping arm pair 311b to perform clamping actions substantially in synchronization from side to side, thereby synchronously clamping the rail 90 from side to side.

In one embodiment, as shown in fig. 24 to 26, the synchronous clamping assembly mainly includes a guide post 317, a synchronous slider 319, a left connecting plate 318a, a right connecting plate 318b provided corresponding to each clamping arm pair 311; the guide post 317 is fixed to the upper surface of the middle of the clamp arm fixing cross member 314, which may be cylindrical, for example, along the central plane 310 of the clamp centering device 31; as shown in fig. 25 and 26, the guide post 317 may be fixedly mounted to the fixed mounting block 3171 of the clamp arm fixing cross member 314 by means of a threaded connection, the fixed mounting block 3171 providing a mounting reference for mounting the synchronized clamping assembly; the synchronous sliding block 319 is provided with a hole corresponding to the guide post 317, so that the synchronous sliding block 319 can be sleeved on the guide post 317 and can linearly slide along the central plane 310; the left connecting plate 318a is used to connect the left end of the synchronization slider 319 to the left arm of the clamping arm pair 311, and the right connecting plate 318b is used to connect the right end of the synchronization slider 319 to the right arm of the clamping arm pair 311, wherein the synchronization slider 319 can be hinged to the left connecting plate 318a and the right connecting plate 318b by a first connecting plate pin 3181, and the left connecting plate 318a and the right connecting plate 318b can be hinged to the left arm and the right arm of the clamping arm pair 311 by a second connecting plate pin 3182 (for example, hinged to a hinge mount of the left arm or the right arm). The synchronization slide 319, the left connecting plate 318a and the right connecting plate 318b in the synchronization clamping assembly are located between the left and right arms of the clamping arm pair 311, and the synchronization slide 319 is designed to be left-right symmetrical with respect to the center plane 310, and the left connecting plate 318a and the right connecting plate 318b are also arranged to be left-right symmetrical with respect to the center plane 310; therefore, the synchronous clamping assembly can synchronously move left and right in the working process, and the synchronous sliding block 319 can be ensured to linearly slide on the guide post 317 and is not easy to be clamped.

In the process that the clamping cylinder 312 drives the clamping arm pair 311 to clamp the steel rail 90, the left arm and the right arm of the front clamping arm pair 311a or the rear clamping arm pair 311b respectively rotate around the clamping arm rotating pin 3141, and the synchronous sliding block 319 can linearly move downwards along the guide post 317 under the driving of the synchronous rotation of the two arms; if the left arm and the right arm of the clamping arm pair 311 temporarily rotate asynchronously, one end of the synchronous slider 319 corresponding to one end of the arm which rotates too fast descends too fast, and one end of the synchronous slider 319 corresponding to one end of the arm which rotates too slow descends too slow, the synchronous slider 319 can incline and temporarily clamp, at this time, the clamping oil cylinder 312 can automatically drive the arm which rotates too slow to continue to rotate until the inclination of the synchronous slider 319 basically disappears, and the left arm and the right arm of the clamping arm pair 311 can continue to synchronously rotate and drive the synchronous slider 319 to continue to linearly move downwards. Therefore, the synchronized clamping assembly of the above embodiment can ensure that the left and right arms of the clamping arm pair 311 perform clamping actions substantially synchronously when clamping. In addition, the introduction of the synchronized clamping assembly, and in particular the guide post 317, prevents the left and right arms of the clamp arm pair 311, together with the clamp cylinder 312, from swinging too far left and right relative to the clamp arm securing beam 314 (because the quadrilateral frame formed between the left and right arms of the clamp arm pair 311, the clamp cylinder 312, and the clamp arm securing beam 314 is not a fixed frame).

In one embodiment, as shown in fig. 19 and 22, the normalizing machine 30 is internally provided with a transformer 33, which transforms the voltage output by the generator set 12, for example, so as to provide corresponding power for the induction coil device 37. The output end of the transformer 33 may be electrically connected to the operating voltage input 331 provided corresponding to the coil 3712, and the transformer 33 may be disposed in an inner space surrounded by the rigid holder 301 and the hanger 36.

In one embodiment, as shown in fig. 28 to 30, the coil opening and closing and translating device 32 can translate in the x direction relative to the clamping and centering device 31 or the rail 90 based on the positioning provided by the clamping and centering device 31 (e.g., based on the positioning reference provided by the clamping and centering device 31), and the coil opening and translating device 32 can drive the induction coil device 37 connected thereto to perform opening and closing actions on the one hand, and can also move the induction coil device 37 parallel to the rail 90 in the front and rear directions to more accurately align with the weld seam of the welding joint on the rail 90 on the other hand, which is very beneficial to improving the normalizing treatment effect.

The coil opening/closing and translation device 32 may specifically include a coil mounting/positioning beam 322, a coil translation guide 327, a coil translation cylinder 3211, and a coil opening/closing cylinder 324 including a left coil opening/closing cylinder 324a and a right coil opening/closing cylinder 324b. An induction coil assembly 37 mounted on the coil mounting location beam 322 may be located within the cavity enclosed by the rigid cage 301 between the front pair 311a and the rear pair 311b of clamp arms.

The coil mounting and positioning beam 322 is hingedly connected with the induction coil device 37, that is, the induction coil device 37 is hingedly connected to the coil mounting and positioning beam 322, illustratively, the left coil supporting plate 373a and the right coil supporting plate 373b of the induction heating coil device 37 are respectively and correspondingly provided with a left hoisting plate 3731a and a right hoisting plate 3731b, the lower ends of the left hoisting plate 3731a and the right hoisting plate 3731b are respectively and detachably and fixedly connected (e.g. bolted) with the upper ends of the left coil supporting plate 373a and the right coil supporting plate 373b, and the upper ends of the left hoisting plate 3731a and the right hoisting plate 3731b are respectively provided with a mounting and positioning hole, so that the upper ends of the left hoisting plate 3731a and the right hoisting plate 3731b can be hingedly connected to the coil mounting and positioning beam 322 through, for example, the pin 3221. Thus, the induction heating coil device 37 can be hung on the coil mounting and positioning beam 322 by the left and right hanging

plates

3731a and 3731b and the pin 3221, and the induction heating coil device 37 is mounted on or hung on the coil mounting and positioning beam 322 and can be moved back and forth along with the coil mounting and positioning beam 322 to move back and forth on the coil mounting and positioning beam.

As shown in fig. 29, when the induction heating coil device 37 is in the closed state, both the left and

right hanger plates

3731a and 3731b are arranged in an "eight" shape such that both the left and right

coil support plates

373a and 373b of the induction heating coil device 37 in the closed state are substantially parallel (e.g., parallel in the z-direction). This is also advantageous in that the coil opening/closing and translation device 32 is more compact in the vertical direction, and the surface contact between the upper left conductive piece 3711a and the upper right conductive piece 3711b and the transformer conductive bar 331 tends to be more natural.

As shown in fig. 28 and 29, the coil opening and closing cylinder 324 may drive the coil of the induction heating coil device 37 to open and close, the coil opening and closing cylinder 324 may be installed between the coil mounting and positioning beam 322 and the induction heating coil device 37, and a left coil opening and closing cylinder 324a may be provided corresponding to a left half of the induction heating coil device 37 and a right coil opening and closing cylinder 324b may be provided corresponding to a right half of the induction heating coil device 37. Specifically, the rear cylinder head of the left coil opening-closing cylinder 324a is hinged to the left end of the coil mounting-positioning beam 322 by, for example, a pin 3241, and the piston rod head of the left coil opening-closing cylinder 324a is detachably hinged to a left coil supporting plate 373a of the induction heating coil device 37 by a pin 3242; the rear cylinder head of the right coil opening/closing cylinder 324b is hinged to the right end of the coil mounting/positioning beam 322 by a pin 3241, for example, and the piston rod head of the right coil opening/closing cylinder 324b is detachably hinged to a right coil support plate 373b of the induction heating coil device 37 by a pin 3242. By controlling the left coil opening/closing cylinder 324a and the right coil opening/closing cylinder 324b to perform the telescopic movement, the left half and the right half of the induction heating coil device 37 can be driven to rotate around the pin 3221, respectively, so that the induction heating coil device 37 can be conveniently controlled to perform the opening and closing actions independently relative to the coil mounting/positioning beam 322.

coil support plates

373a and 373b are returned to the open state, and the induction heating coil device 37 is returned to the open state.

The coil opening and closing and translating device 32 further includes one or more coil translating sliders 328 provided corresponding to the coil mounting and positioning beams 322, the one or more coil translating sliders 328 on each coil translating rail 327 are linearly slidable in the front-rear direction along the coil translating rail 327, and the coil mounting and positioning beams 322 are coupled to the coil translating sliders 328 by slider connecting plates 3281, so that the coil translating rails 327 are linearly translationally slidable along the coil translating rails 327.
