The multifunctional electric control abrasive belt steel rail refiner further comprises a horizontal traversing device. Wherein the lifting pressure device, the angle deflection device and the horizontal traversing device are also arranged, carried, connected, supported or mounted by the chassis and are preferably arranged in the space enclosed by the chassis. Therefore, the multifunctional electric control abrasive belt steel rail refiner can deflect, transversely move (in the direction perpendicular to the extending direction of the steel rail) and vertically feed around the steel rail, achieves the purpose of polishing damages such as weld joints, traffic surfaces and welding beading at the weld joints of the steel rail by +60 degrees to-30 degrees, corrects the profile of the rail head, and meets the polishing and maintenance requirements.

Hereinafter, each of the above-described devices, mechanisms, elements, components, and the like will be described in detail.

< Chassis >

The chassis (or called frame, walking frame) 2 is used for arranging, supporting, connecting, installing or carrying various devices, mechanisms, elements, components and the like of the multifunctional electric control abrasive belt steel rail refiner and guiding the multifunctional electric control abrasive belt steel rail refiner to walk along the steel rail. For example, in the illustrated embodiment, the wheel sharpening unit is indirectly connected to the base frame by a lift press, by an angular deflection by a horizontal traversing device. Of course, it will be understood by those skilled in the art that the connection of the wheel sanding device, the lifting and pressing device, the angular deflection device, and the horizontal traversing device to the undercarriage may be combined in any combination, and is not intended to be limiting. That is, at least one of the wheel grinding device, the lifting and pressing device, the angle deflecting device, and the horizontal traversing device may be directly connected to the frame, or may be indirectly connected to the frame through any one of them.

As best shown in fig. 2, the chassis 2 is configured in a generally rectangular shape. For example, four beams constitute the substantially rectangular shape. Further, to facilitate miniaturization of the multifunctional electrically controlled abrasive belt rail refiner, the length of the beam extending parallel to the rail direction (longitudinal direction) is smaller than the length of the beam extending perpendicular to the rail direction (lateral or horizontal direction). Therefore, hereinafter, the laterally extending beams are referred to as "primary beams", and the longitudinally extending beams are referred to as "secondary beams". The main beam comprises a telescopic rod to adjust the length of the main beam, so that the multifunctional electric control abrasive belt steel rail refiner disclosed by the invention can adapt to steel rails embedded according to different spacing specifications.

As shown in fig. 1, most of the devices, elements, etc. constituting the multifunctional electrically controlled abrasive belt rail refiner of the present disclosure are defined in the space enclosed by the chassis 2.

In order to facilitate the operation of the multifunctional electric control abrasive belt steel rail refiner, a push rod handrail 6 is arranged on the underframe 2. The push bar handle 6 may be a member detachably attached to the base frame 2, for example, by riveting, fastening, or the like, or may be a member extending from a main beam of the base frame 2 and integrated with the base frame 2. In one embodiment, the pusher handrail 6 extends upwardly from the 2 main beams and meets at a top end to assume a generally inverted U-shape. When the multifunctional electric control abrasive belt steel rail refiner runs, a worker can put the hand on the push rod handrail 6 to operate the advancing and retreating of the multifunctional electric control abrasive belt steel rail refiner. Where a horizontal traversing device is provided, the pusher handrail 6 may be attached (e.g., removably mounted by riveting, fastening, etc.) to the horizontal traversing device, rather than to the main beam.

In addition to the push bar handle 6, at least one of the two sides of the chassis 2 (perpendicular to the direction in which the rails extend) may be provided with a handle 16 for gripping by a worker to assist in the handling of the multifunctional electrically controlled abrasive belt rail refiner. Fig. 1 shows four handles 16.

In order to facilitate the multifunctional electric control abrasive belt steel rail refiner to walk along the steel rail, a moving device, such as a guide wheel 1, is arranged below the underframe 2. The guide wheel 1 may be connected to the base frame 2 by riveting, welding, etc., preferably to a guide wheel post 2a extending from the base frame 2 in the direction of the rail.

The number of guide wheels 1 is not limited, and four guide wheels 1 are preferably provided so that 2 guide wheels contact one steel rail.

To ensure that the runner 1 can travel on the rail without coming off the rail, a stopper 1a is provided on the runner 1. Fig. 2 shows an embodiment of the stop 1 a. The stopper 1a is configured as a circular disk having a diameter larger than that of the guide wheel 1, and is coaxially mounted on the side surface of the guide wheel 1. The diameter of the stop 1a ensures that a portion of the stop 1a covers a portion of the rail after it is mounted on the guide wheel 1. A stopper 1a may be provided at one side of the guide wheel 1 (as shown). Alternatively, the stoppers 1a may be provided on both sides of the guide pulley 1. When the stop 1a is provided on only one side of the guide wheel 1, the stop 1a is mounted so that the stops 1a on different guide wheels cooperate with each other to prevent a wide range of movement of the sander in the transverse direction. For example, the guide wheels may be mounted as follows: the sides of the guide wheels having the stoppers 1a are all located inside the rail or all located outside the rail.

Preferably, an insulator (not shown) is disposed between the guide wheel 1 and the base frame 2 to prevent static electricity and the like caused by friction between the guide wheel 1 and the steel rail from interfering with other devices or elements and the like of the multifunctional electrically-controlled abrasive belt steel rail refiner.

< Power supply device >

The power supply device is used for supplying power to one or more of various devices, mechanisms, elements and components in the multifunctional electrically-controlled abrasive belt steel rail refiner. Preferably, the power supply means supplies power to a motor 7 and a stepping motor 8 (described later) in the belt sander and the lift press device.

The power supply device is supported by the chassis 2. The power supply means may be mounted directly on the chassis 2. Alternatively, the power supply device is mounted to the base frame 2 by a support fixed to the base frame 2. The support may be, for example, a support plate 51 as shown in fig. 2. The support plate 51 is fixed between the main beams of the base frame 2 by means of, for example, welding. A catch plate 52 for supporting the sprocket cassette 9 described later may be fixed to the side of the support plate.

The power supply is preferably located on the opposite side of the chassis 2 to the belt sander described later, e.g. as shown in fig. 1, the power supply is located on the left side (first side) of the chassis 2 and the belt sander is located on the right side (second side) of the chassis 2. This is advantageous in maintaining the balance of the belt sander itself.

As shown in fig. 1, the power supply device includes a battery case 3 and an electric case 4 that are separately arranged. Alternatively, the power supply device is in an integrated mode, i.e., the battery box 3 and the electrical box 4 are integrated in one housing.

The installation of the battery box 3 and the electrical box 4 is not limited. In the case of including the battery box 3 and the electrical box 4 which are separately arranged, the battery box 3 may be mounted on a battery box platform, while the electrical box 4 is mounted on an electrical box platform. The battery box platform and the electric box platform are respectively fixed with the underframe 2. Alternatively, both are mounted on the support plate 51.

The power supply means may take the form of a removably rechargeable battery, or other form. The rechargeable battery is removably arranged in the battery box 3. Alternatively, the battery box 3 may not be provided, and the battery may be directly placed on the chassis or the battery box platform. In some cases, power may be taken directly from the polishing site.

An electrical matching system is arranged in the electrical box 4, and modules for motor operation control, safety protection, light and the like are arranged in the electrical box. Preferably, the electrical box is further provided with a display to display the remaining capacity of the battery.

< sanding apparatus with abrasive belt >

Belt sanding devices are used to sand steel rails to eliminate or reduce wave wear (or other damage).

The abrasive belt grinding device is arranged on the underframe 2. In one embodiment, the belt sander is mounted to rail support 16. With a lifting press described later, the belt sanding device is mounted to the lifting press and both devices are located on the second side of the undercarriage.

In an embodiment, the belt sander comprises a post (or holder, square tube) 34, a drive wheel 31, a tension wheel 28, a contact wheel 26, and a sanding belt 27. The drive wheel 31, tension wheel 28 and contact wheel 26 are mounted or positioned relative to the support post 34. Wherein the driving wheel 31 is connected with the motor 7 to obtain driving force. The contact wheel 26 is used to bring the abrasive belt 27 into contact with the rail and is set at such a height that the abrasive belt 27 wound thereon can be brought into close contact with the rail to be ground to achieve grinding of the rail or the height can be adjusted. The outer peripheral surface of the contact wheel 26 is provided with a rubber layer or other suitable soft or resilient material, whereby vibrations during sanding can be reduced.

In one embodiment, the strut 34, drive wheel 31, tension wheel 28, contact wheel 26 and abrasive belt 27 are arranged as follows. As shown in fig. 6, the driving wheel 31 is located at the upper portion of the column 34, the contact wheel 26 is located at the lower portion of the column 34 with respect to the driving wheel 31, and the tension wheel 28 is located between the driving wheel 31 and the contact wheel 26. Preferably, the drive wheel 31 and the contact wheel 26 are arranged aligned in the vertical direction (height direction) on the pillar 34, while the contact wheel 26 is offset outwardly from the pillar 34, so that the drive wheel 31, the tension wheel 28 and the contact wheel 26 form a substantially triangular configuration to contribute to adjusting the tension of the sanding belt 27. The distance and angle at which the tensioner 28 is biased outwardly from the post 34 are both set to be adjustable.

The drive wheel 31 and contact wheel 26 are mounted on the support post 34 using any suitable technique known in the art, provided that rotation of the drive wheel 31 and contact wheel 26 is ensured. The specific installation method is not described herein.

In order to adjust the tension of the sanding belt 27, the mounting between the tensioning wheel 28 and the strut 34 can be chosen such that the horizontal distance and the angle between the tensioning wheel 28 and the strut 34 are adjustable. For example, in an embodiment, a tensioning mechanism is provided on the strut 34, and the end of the tensioning mechanism is connected to the tensioning wheel 28. As shown in FIG. 8, in one embodiment, the tensioning mechanism includes, for example, a handle 36, a tensioning link 37, and a spring 48. Tension link 37 connects handle 36 and spring 48. Spring 48 connects tension link 37 and tension wheel 28. By actuating tensioning link 37 by pulling handle 36, the compression force of adjustable spring 48 in turn adjusts the position of tensioning wheel 28, thereby tensioning or releasing sanding belt 27. The tensioning mechanism may also include a tensioning jacket.

The abrasive belt 27 is wound around the outer circumference of the driving wheel 31, the tension wheel 28 and the contact wheel 26 to form a circulating closed loop. When the multifunctional electric control abrasive belt steel rail refiner operates, the abrasive belt 27 continuously enters into contact with the steel rail. After the abrasive belt is worn, the abrasive belt can be replaced. When the abrasive belt is replaced, the handle 36 is pulled, the connecting rod 37 drives the abrasive belt to be replaced, the spring 48 is compressed, the tension wheel 35 is loosened, and the abrasive belt can be taken down or replaced. This embodiment utilizes a spring 48 for tensioning. Other tensioning mechanisms are also possible, such as a step-by-step adjustment mechanism, which will not be described in detail herein.

In a further embodiment, the belt sanding device further comprises a belt cover 30 covering the outside of the sanding belt 27 to protect the sanding belt 27. The belt cover 30 is preferably arranged on the entire belt 27 except for the part in contact with the contact wheel 26 and close to the contact wheel 26.

< lifting/lowering pressing device >

In order to realize that the abrasive belt polishing paper can move up and down along the height direction, a lifting pressure device is arranged on the underframe 2. In the case of having an angle deflecting device described later, the elevation pressing device is attached to the angle deflecting device. In addition, the lifting and pressing device is connected with the belt sanding device to control the height of the latter.

The construction of the lifting press is best seen in figure 5. The lifting pressure applying device comprises a guide rail support 16, a lifting platform 24, a lifting screw 25, a coupler 23, a lifting slider 22, a motor 7 and a stepping motor 8. The rail support 16 is preferably cylindrical. The guide rail 21 is fixed on the guide rail support 16, the slider 22 is slidably connected to the guide rail 21, the lifting platform 24 penetrates through the lifting screw 25 and is fixed on the lifting slider 22, the motor 7 is fixed on the lifting platform 24, and the stepping motor 8 is connected with the lifting screw 25 through the coupler 23 to drive the lifting screw 25 to rotate so as to realize longitudinal displacement of the mechanism. The stepping motor 8 and the lifting screw 25 are both connected (or fixed) with the guide rail support 16.

Therefore, the lifting pressure device adopts the linear module and the screw rod sliding block, and has good guidance performance and stability.

A scale pointer (not shown) is also mounted on the lifting and pressing device to visually display the height of the belt sander.

In the case where an angle deflecting device described later is provided, the lifting and pressing device further includes a member (a rail support 16 in the present disclosure) for connecting with the angle deflecting device. In this case, the belt sanding device can be connected to a lifting pressure device, which is connected to an angle deflection device, which is connected to the base frame 2.

< Angle deflecting device >

In order to realize that the angle of the abrasive belt grinding device relative to the steel rail can be adjusted, an angle deflection device is arranged. In the case of a horizontal traverse device described later, the angle deflecting device is provided in connection with at least one of the traverse frame and the base frame of the horizontal traverse device. The angle deflection means is connected directly or indirectly to the belt sanding device for controlling the height of the latter. For example, the angle deflection device is connected to a lifting pressure device, which is connected to a belt sander. The angular deflection means are integrally connected to the guide rail support 16. The angle deflection device is connected to a lifting pressure device via a guide rail support 16, which lifting pressure device is connected to the belt sander. The angle deflection means is mounted to one side of the rail support 16 and the lifting pressure means is mounted to the other side of the rail support 16. The rail supports 16 are connected to the base frame 2 (or the traverse frame 12).

As shown in fig. 4, the angle deflecting means includes a swing hand wheel 18, a hand wheel shaft 18a, a deflecting pinion 37, a rack 19, and the like. The rack 19 is installed on a rack fixing plate 20, the rack fixing plate 20 is connected with the guide rail support 16 through bolts and the like, and the rack fixing plate is provided with corresponding circular lightening holes. Thus, the operator can change the angle of the belt sander relative to the rail by operating the swing hand wheel 18. The oscillating hand wheel 18 is connected to a deflection pinion 37 via a hand wheel shaft 18a, the deflection pinion 37 engaging with a toothed sector on the guide rail support 16. When the swinging hand wheel 18 is rotated, the angle deflection device as a whole with the belt sander is deflected (to the left or to the right).

The angle deflection means also comprises a set of brake wedges 17 to enable locking of the angle deflection means in any position. The brake wedge set 17 is provided with a brake block which can be directly inserted into a rack gap of the rack 19 to realize locking and positioning.

In order to visually represent the angle of the belt sander relative to the rail, a scale 15 is provided on the angle deflection device, on which scale 15 the angle of deflection can be displayed. The scale 15 is attached to the rack fixing plate by means of, for example, rivets.

In the case where a horizontal traverse device described later is provided, the angle deflecting device further includes a member for connecting with the horizontal traverse device (for example, "60", and in the case where the horizontal traverse device is not provided, the member may be, for example, a member for connecting the angle deflecting device to the base frame 2). In this case, the belt sanding device may be connected to a lifting pressure device, which is connected to an angle deflection device, which is connected to a horizontal traversing device, which is connected to the chassis 2. As shown, the member 60 is, for example, a trapezoidal shaped bracket, sized and configured to securely support an angular deflection device or the like. For example, the trapezoidal bracket is formed by connecting square pipes with the thickness of at least 15mm, the wall thickness of the trapezoidal bracket is at least 1.5mm, and the trapezoidal bracket is made of metal. Preferably, the trapezoid support is formed by connecting square pipes with the sizes of 20mm, 26mm, 28mm, 30mm, 33mm, 37mm and the like. The wall thickness is selected from 2.0mm, 2.3mm, 2.5mm, 2.8mm, 3.0mm, 3.4mm, 3.5mm, etc. Examples of the material include steel and aluminum alloy. In the embodiment, the trapezoid support is a 30mm square tube with the wall thickness of 2.5mm and is made of Q235-B. The grinding wheel sharpening device may be connected to a lifting pressure application device connected to an angular deflection device connected to a horizontal traverse device connected to the base frame 2.

< horizontal traverse device >

In order to realize that the multifunctional electric control abrasive belt steel rail refiner can move along the direction (transverse direction, left and right) vertical to the steel rail, a horizontal traversing device is arranged on the underframe 2. In particular, the traverse frame 12 of the horizontal traverse device is provided to be slidably connected with the base frame 2. The horizontal traversing device is directly or indirectly connected with the abrasive belt grinding device.

As best shown in fig. 3, the horizontal traverse device includes a traverse frame 12, a traverse mandrel 11, a lead screw 14, a sprocket cassette 9, and a traverse hand wheel 10. Preferably, the horizontal traversing device further comprises wheels 13.

The traverse frame 12 is configured in a substantially rectangular shape, for example, composed of 4 beams, and has substantially the same size in the longitudinal direction as the base frame 2. The wheels 13 include 4 wheels installed at 4 corners of the traverse frame 12, or 3 wheels may be provided, constituting a substantially triangular shape. The wheels 13 are preferably U-shaped wheels. The rolling contact portions (central recessed portions) of these U-shaped wheels 13 are in contact with the main beams of the base frame 2 to guide the traverse frame 12 to move along the main beams. The traverse mandrel 11 is positioned in the traverse frame 12 and connected to 2 beams of the traverse frame 12 parallel to the main beams. On which at least one of the aforementioned angle deviation device, lifting and pressing device, belt sanding device may be mounted.

The traverse frame 12 is connected at one end to a sprocket wheel in a sprocket wheel cassette 9 mounted to the frame 2, for example, by a lead screw 14, and at the other end to the frame 2 by a U-shaped wheel 13. The chain wheel connected to the spindle 14 is connected via a chain to a further chain wheel which is connected to the traversing hand wheel 10 via a chain shaft. The movement of the horizontal traversing mechanism can be realized by rotating the traversing hand wheel 10. Wherein the aforementioned sprocket cassette 9 is fixed to the support plate 51 by the fixing member 52.

In the case of a horizontal traverse device, the belt sanding device, the angle deflection device and the lifting and pressing device described above are connected directly or indirectly to the traverse frame 12 (or the traverse mandrel 11) instead of to the base frame 2, so that these devices as a whole can be moved horizontally in synchronism.

The horizontal traversing device is connected with the traversing frame through the lead screw, and has the characteristics of low shaking speed, difficulty in damaging equipment and benefit for polishing operation.

It will be appreciated by those skilled in the art that one or more of the angle deflection means, lifting pressure means and horizontal traversing means may or may not be incorporated into the multifunctional electrically controlled belt refiner of the present invention, depending on the grinding needs. As will be appreciated by those skilled in the art in light of the present disclosure, belt sander apparatus may be connected to undercarriage 2 or belt sander apparatus may be connected to undercarriage 2 without one or more of the angular deflection apparatus, lifting press and horizontal traverse apparatus. And will not be described in detail herein.

< control Panel >

The multifunctional electric control abrasive belt steel rail refiner also comprises a control panel, and the structure of the control panel is shown in figure 7.
