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 off-line or on-line 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 main body of the rail working vehicle 20 is formed with a substantially flat-plate-shaped 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, at present, 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, even the corresponding diesel engine and the like can be shared by the rail working system 10 and the rail working vehicle 20, and the diesel engine and the like are not required to be specially arranged on the rail working vehicle 20 in the traditional mode 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 of 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 and is easy to accept by users, in addition, the structure is simple, the required installation space is small, and in addition, the electric drive can be realized.

It should be understood that the above "common use" is made by the applicant considering the application characteristics of the rail field work system 10 that does not require electric power to be used for the field work when it is carried, and the rail field work system 10 that does not require electric power to be driven for the rail work vehicle 20 to travel when the field work is carried out, and therefore, which can simultaneously meet the application requirements of the rail operating vehicle 20 and the rail field operating system 10, even if the generator set 12 is shared, the problem of contradiction between the power requirements of the rail operating vehicle 20 and the rail field operating system 10 is not caused, the power of the traction motor 221 is easily ensured, the characteristic of high-power driving requirement of rail transportation is easily met, and the limitation of the endurance mileage is basically avoided (for example, if a power battery module is adopted to supply power to the traction motor 221, the endurance mileage and the power are difficult to meet the requirement of the rail field operating system 10 with heavy load). 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, which in turn drives the wheels 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; 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 pairs are 2 groups as an example, and a transmission shaft 223, a universal coupling 225, an axle gear box 227 and a traction motor 221 are correspondingly arranged on the front and rear wheel pairs respectively, so that the wheel pairs can be driven respectively. 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 carry any type of rail field working system 10 with a generator set by providing the locking assembly 212, the corresponding traction motor 221 and the electric transmission assembly, and can also be used for carrying 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 °), causes the head of the twist lock 2121 to at least partially seat in the recess 2126 of the boss 2125 and be restrained from rotation by the recess 2126, the twist lock nut 2122 is threadedly secured to the lower end of the shaft of the twist lock 2121 when locked, and the cotter pin 2124 passes through a through hole on the lower end of the shaft of the twist lock 2121 to prevent the twist lock nut 2122 from being threadedly 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, 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 use; 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 plurality of locking assemblies 212 complete the operation of locking the nacelle 11 to the rail working vehicle 20; when the cabin 11 needs to be detached from the rail working vehicle 20, the cotter 2124 can be removed, the rotational lock nut 2122 can be unscrewed, and the rotational lock 2122 can be lifted and rotated in the reverse direction by 90 degrees, at this time, the rotational 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 reversing by applying 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 one end of the site is provided as a tow hook 25b having a lower height without a decoupling device, for example, the upper end surface of the tow hook 25b is lower than the height of the underframe of the nacelle 11. In this way, when the crane 16 conveys the induction type normalizing treatment device 30, the tow hook 25b does not collide with the induction type normalizing treatment device 30, and the tow hook 25b does not interfere with or affect the conveying 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 light 219 can provide a safety prompt to a field worker 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 with reference to 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 the set of generator set 12, so that the steel rail operation vehicle 20 can be driven to travel on a steel rail through the power provided by the generator set 12 when carrying the steel rail field normalizing operation system 10, self-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 on-site normalizing operations, and the bottom frame of the cabin 11 is used for carrying the devices, 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 lighting windows, 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 a cabin door 119 at a tail end of the cabin 11, and a lighting window 1133 (as shown in fig. 14) disposed on a partition 119 of the cabin 11; the cabin 11 may also be provided with a plurality of access hatches for the ingress and egress of workers, for example, one or more access hatches 1141 (shown in fig. 11) disposed on the side of the cabin 11, an access hatch 1142 (shown in fig. 12) disposed at the front end of the cabin 11 to facilitate access to the cab 24 from within the cabin 11, and an access hatch 1143 (i.e., an access door, shown in fig. 14) disposed on the compartment 119 of the cabin 11; the nacelle 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 nacelle 11, a louver 1152 (shown in FIG. 12) disposed at a front end of the nacelle 11, and a louver 1153 (shown in FIG. 14) disposed at the compartment 119 of the nacelle 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), an induction normalizing treatment unit 30, an electrical control cabinet 14, a chiller unit 15, a crane 16, a hydraulic power unit 17, a normalizing management system 18, a blower unit 19, an exhaust gas purification unit 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 induction normalizing device 30 performs normalizing by electromagnetic induction heating of the welding head of the steel rail by the electromagnetic coil, and thus the generator set 12 is required to generate power on site to provide power required for 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 induction type normalizing treatment device 30, for example, when the field normalizing treatment is started, the crane 16 can hoist the induction type normalizing treatment device 30 in the cabin body 11 to the steel rail outside the cabin body 11, even accurately hoist the steel rail to the position of the welding joint to be subjected to heat treatment; after the normalizing process is completed, the induction type normalizing process device 30 can be hoisted back into the cabin body 11.

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

The normalizing management system 18 is used for managing the heat treatment process of the induction type normalizing treatment device 30 and storing corresponding normalizing treatment 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 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 assembly 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, the cooling fan may take away a large amount of heat generated in the direction in which the induction type normalizing processing device 30 is located, even heat generated inside the rail on-site normalizing operation system 10 in another direction in an airflow manner (for example, 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 induction type normalizing treatment device 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 shown in fig. 10, the generator set 12 is optionally 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, i.e., a diesel tank of the diesel engine 121 is realized 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 nacelle 11 may be provided with a work illumination lamp 1101 arranged at an end (e.g., the tail end) of the nacelle 11 near a field work site, which may be used to provide illumination during field work, improving 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 hatch 116 is opened, the opening and closing device 117 can push the main hatch 116 to rotate around the upper end thereof, so as to open the main hatch 116, and thus the crane 16 can conveniently carry and operate the induction type normalizing treatment device 30; conversely, the primary hatch 116 may be closed.

In order to facilitate the handling of the induction normalizing device 30, a corresponding auxiliary control panel 109 may be disposed at a lower portion of at least one side of an 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 by operating the auxiliary control panel 109, an operator outside 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.

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 induction type normalizing treatment device 30, so as to conveniently and accurately move the induction type normalizing treatment device 30 from the cabin 11 to a field operation point (for example, a station aligned with a welding joint); after the normalizing process is completed, for example, the crane 16 may lift and move the induction normalizing process apparatus 30, move the induction normalizing process apparatus 30 from the on-site operation site into 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. The two ends of the connecting rod 1172 are hinged to the outer end 1174 and the main compartment door 116, respectively, and the outer end 1174 of the piston rod 1175 of the hydraulic 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 the horizontal direction, so that piston rod 1175 of hydraulic cylinder 1171 keeps horizontal telescopic movement, and further, outer end 1174 transmits the acting force of hydraulic cylinder 1171 to main compartment door 116 through connecting rod 1172, so that opening and closing of main compartment door 116 of compartment 11 can be conveniently completed. 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 operation room may be specifically selected as a single-boom crane, the front end of the boom body of the single-boom crane 16 is connected to a rotatable hanger 361 (shown in fig. 18) of the induction normalizing treatment device 30 through a flexible chain (not shown), and the induction normalizing treatment device 30 can be lifted under the action of corresponding cylinders of the crane 16. The single-arm crane 16 is more suitable for use in the case of the single-arm lifting induction normalizing device 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 is inclined due to the inconsistent height of the left and right rails of the rail at the bend, the z direction indicated in the figure will not coincide with the gravity direction, when the crane lifts the induction type normalizing treatment device 30, the flexible chain is at the gravity direction and will 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 induction type normalizing treatment device 30 to interfere and collide with one of the two booms of the crane, which is very unfavorable for the retraction and extension of the induction type normalizing treatment device 30, and is also unfavorable for the accurate alignment of the induction type normalizing treatment device 30 relative to the welding joint station, and simultaneously shortens the service life of the flexible chain; 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 means 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 telescopic in its longitudinal direction with respect to the base arm 164, and specifically is driven to extend or retract with respect to the fixed arm 164 by a telescopic cylinder 162 provided in its longitudinal direction, so that the telescopic arm 165 and the base arm 164 together form a telescopic arm body. The front end of the telescopic arm 165 is connected to a rotatable spreader 361 (shown in fig. 18) of the induction normalizing treatment apparatus 30 by a flexible chain (not shown).

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

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 induction type normalizing treatment device 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 and locked towards the x direction, in the moving process, considering that the weight of the lifted induction type normalizing treatment device 30 is large, the centers of the crane 16 and the induction type normalizing treatment device 30 are deviated towards the x direction, the pair of vertical rolling bearings 113 close to the field operation direction press downwards 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 press downwards 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 limited 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 operating requirements of the crane, and accordingly, no bearing may be installed on the sliding plate 112.

The above examples mainly describe the rail on-site normalizing operation system and the rail on-site operation assembly using the rail on-site normalizing operation system according to the present invention. Although only a few embodiments of the present invention have been described, those skilled in the art will appreciate that the present invention may be embodied in many other forms without departing from the spirit or scope thereof. Accordingly, the present examples and embodiments are to be considered as illustrative and not restrictive, and various modifications and substitutions may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
