Description

Technical Field

[0001] The present application relates to the field of rail processing equipment, and in particular to a transverse movement device for rail finishing and grinding equipment. Background Art

[0002] Railway is an important part of my country's transportation, and railway track is one of the basic infrastructures of railway transportation. In particular, turnout sections and small radius curves are the three weak links of railways together with curves and joints due to their large number, complex structure, short service life, speed limit, low driving safety, and large maintenance investment.

[0003] Since my country's railway tracks are of various types, suitable for different railway transportation modes and geographical environments, in order to better adapt to the rapid development of modern railways, we have developed a new intelligent rail repair.

[0004] However, during use, since there are multiple branch tracks between the turnout tracks, they are also located on the track and connected to the grinding equipment through a swing arm, and the swing arm has a fixed length. This requires multiple moves and installations on different tracks to fully grind the track, which takes a lot of time to install the equipment, which is troublesome. Summary of the invention

[0005] In order to facilitate the grinding of rails at different distances, the present application provides a transverse movement device for rail dressing and grinding equipment.

[0006] The present application provides a transverse movement device for rail dressing and grinding equipment adopts the following technical solution: A transverse movement device for rail dressing and grinding equipment comprises a swing arm, wherein a transverse movement motor is arranged inside the swing arm, wherein the output shaft of the transverse movement motor is connected to a reducer, wherein the reducer is connected to a transverse movement screw, wherein the external thread of the transverse movement screw is sleeved with a transverse movement block, and the transverse movement block is connected to the grinding device.

[0007] By adopting the above technical solution, when it is necessary to move the grinding device according to the current position of the rail, the transverse motor is turned on to drive the transverse screw to rotate through the reducer. The transverse screw drives the transverse block to move during the rotation process. The transverse block drives the connected grinding device to move during the movement, thereby reducing the trouble caused by the need to move the equipment body due to changes in the distance between the rail to be ground and the equipment body.

[0008] Optionally, the transverse movement block is connected to a locking assembly for fixing the position of the transverse movement block.

[0009] By adopting the above technical solution and setting the locking assembly, the position of the lateral block changes during the grinding process, which causes the position of the grinding device to change and affects the grinding effect.

[0010] Optionally, the locking assembly includes a lock box connected to the transverse block, a push plate is slidably inserted inside the lock box, the push plate is connected to a drive assembly, and the drive assembly is used to drive the push plate to abut against the inner wall of the adjacent swing arm when the transverse motor stops rotating.

[0011] By adopting the above technical solution, when the transverse movement motor stops rotating, the driving assembly drives the push plate to abut against the inner wall of the swing arm, thereby limiting the position of the transverse movement block.

[0012] Optionally, a plurality of tooth blocks are fixedly connected to one side of the push plate close to the inner wall of an adjacent swing arm, and a tooth plate corresponding to the tooth blocks is fixedly connected to the inner wall of the swing arm.

[0013] By adopting the above technical solution, when the push plate moves to a position close to the adjacent swing arm, the tooth block on one side of the push plate abuts against the tooth plate, thereby reducing the phenomenon that it is difficult to limit the position of the transverse block when the push plate abuts against the swing arm.

[0014] The transmission gear of the present invention is connected with the gear of the transmission gear of the present invention, and the gear of the transmission gear is connected with the gear of the transmission gear of the present invention to the gear of the transmission gear.

[0015] By adopting the above technical solution, when the traverse motor rotates, the traverse motor drives the driving screw and the traverse screw to rotate at a differential speed through the driving gear and the driven gear, so that the driving screw can drive the driving block to move relative to the traverse block, and the driving block drives the driving rack to move during the movement, and the driving rack drives the follower gear to rotate during the movement, and the follower gear drives the working screw and the push block to move in the direction close to the traverse block during the rotation, so that the push plate is difficult to abut against the adjacent tooth plate driven by the tension spring; After the traverse motor stops rotating, the compression spring drives the push block to move toward the side close to the push plate, so that the push plate can move toward the side close to the tooth plate and abut against the tooth plate, thereby limiting the position of the traverse block.

[0016] Optionally, the push plate is connected to an auxiliary positioning piece for abutting against the inner wall of the swing arm.

[0017] By adopting the above technical solution, when the push plate abuts against the inner wall of the swing arm, the auxiliary positioning member abuts against the inner wall of the swing arm at the same time, thereby further fixing the position of the transverse movement block.

[0018] Optionally, the auxiliary positioning member is configured as an auxiliary rod fixedly connected to the push plate, and a side of the auxiliary rod away from the push plate to which it is connected can abut against the inner wall of the swing arm opposite to it.

[0019] By adopting the above technical solution, when the push plate abuts against the inner wall of the adjacent swing arm, the auxiliary rod abuts against the inner wall of the adjacent swing arm, thereby achieving a reinforcement effect on the position of the transverse movement block.

[0020] Optionally, a universal joint is connected between the reducer and the transverse screw.

[0021] By adopting the above technical solution, the phenomenon that when the grinding device is deflected, the driving screw is difficult to rotate, making it difficult for the traverse block to move, or the driving screw is difficult to rotate through the traverse motor after the driving screw is rotated is reduced.

[0022] Optionally, a pull rope sensor for monitoring the position of the transverse block is provided inside the swing arm.

[0023] By adopting the above technical solution, the phenomenon that the distance that the lateral movement block is driven by the lateral movement motor is difficult to control is reduced.

[0024] Optionally, an end cover for sealing an opening at the end of the swing arm is fixedly connected to the end of the swing arm.

[0025] By adopting the above technical solution, the dust is reduced from entering the swing arm, affecting the coordination between the transverse screw and the transverse block, and causing wear on the transverse screw.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting a traverse motor and a reducer connected to the traverse screw, and the traverse screw connected to the grinding device through the traverse block, the relative distance between the grinding device and the grinding device body is reduced, which reduces the trouble of moving the entire device when the distance between the track and the device body changes; 2. By setting a locking device, the position of the transverse block can be fixed, reducing the displacement of the grinding device due to contact with the track during the grinding process, thereby making it difficult to fully grind the track.

[0030] The following is combined with Figure 1 -Attached Figure 2 This application is described in further detail.

[0031] The embodiment of the present application discloses a transverse movement device for rail dressing and grinding equipment.

[0032] Example 1 Reference Figure 1 A transverse movement device for rail dressing and grinding equipment includes a swing arm 1, which is connected to the equipment body through a support 11. A transverse movement motor 2 is arranged inside the swing arm 1, and the output shaft of the transverse movement motor 2 is arranged along the length direction of the swing arm 1. The output shaft of the transverse movement motor 2 is connected to a reducer 21, and a rear bearing seat 12 is sleeved on the output end of the reducer 21. The output end of the reducer 21 passes through the rear bearing seat 12 and is connected to a transverse movement screw 3. The length direction of the transverse movement screw 3 is arranged along the length direction of the swing arm 1.

[0033] The end of the traverse screw 3 away from the reducer 21 is sleeved with a screw bearing 13, and the screw bearing 13 is sleeved with a front bearing seat 14. The end of the swing arm 1 close to the front bearing seat 14 is fixedly connected with an end cover 15 for sealing the end opening of the swing arm 1.

[0034] The external thread of the traverse screw 3 is sleeved with a traverse block 4, and two opposite side walls of the traverse block 4 are slidably abutted against the inner wall of the swing arm 1 along the length direction of the swing arm 1. The traverse block 4 is connected to an external grinding device of the swing arm 1.

[0035] In actual use, when the device is fixed but the position of the grinding device needs to be adjusted, the traverse motor 2 is turned on, and the traverse motor 2 drives the traverse screw 3 to rotate through the reducer 21. The traverse screw 3 drives the traverse block 4 to move during the rotation process, and the traverse block 4 drives the grinding device to move during the movement process, thereby adjusting the position of the grinding device, so that the device can adapt to more grinding scenarios.

[0036] The output end of the speed reducer 21 is connected to the traverse screw 3 via a universal joint 31 .

[0037] By providing the universal joint 31, when the grinding device drives the lateral block 4 to deflect, the lateral motor 2 can still drive the lateral screw 3 to rotate through the reducer 21, so that the device can adapt to more grinding scenarios.

[0038] A pull-wire sensor 5 is provided inside the swing arm 1 , and the pull-wire sensor 5 is connected to the transverse movement block 4 .

[0039] The position of the transverse block 4 is monitored by the pull-wire sensor 5 , so that the transverse motor 2 can control the moving position of the transverse block 4 more accurately.

[0040] The implementation principle of Example 1 is: when the grinding device needs to be moved, the transverse motor 2 is started to drive the transverse screw 3 to rotate through the reducer 21 and the universal joint 31. The transverse screw 3 drives the transverse block 4 to move during the rotation process. The transverse block 4 drives the grinding device to move during the movement, thereby realizing the adjustment of the position of the grinding device according to the distance between the current equipment and the required grinding track.

[0041] Example 2 Reference Figure 2 The difference between the embodiment of the present application and embodiment 1 is that the transverse block 4 is connected to a locking assembly 6 for fixing the position of the transverse block 4.

[0042] By providing the locking assembly 6, during the grinding process, the grinding device can be located at the current position to grind the rail more stably.

[0043] The locking assembly 6 includes a lock box 61 fixedly connected to two opposite side walls of the traverse block 4 not connected to the grinding device. A push plate 62 is slidably inserted inside each lock box 61, and the side wall of the push plate 62 is slidably connected to the adjacent lock box 61. A plurality of tooth blocks 621 are fixedly connected to the side of the push plate 62 away from the traverse block 4. A tooth plate 63 capable of abutting against the adjacent push plate 62 is fixedly connected to the inner wall of the swing arm 1 near each lock box 61.

[0044] Each push plate 62 is connected to a driving assembly 7 , and each driving assembly 7 is connected to the transverse movement motor 2 , and can drive the connected push plate 62 to move toward the side close to the tooth plate 63 and abut against the adjacent tooth plate 63 when the transverse movement motor 2 stops rotating.

[0045] In actual use, when the traverse motor 2 rotates, the driving assembly 7 drives the push plate 62 to move to the side away from the adjacent tooth plate 63. At this time, the traverse motor 2 can drive the traverse block 4 to move by driving the traverse screw 3 to rotate. When the traverse motor 2 stops rotating, the driving assembly 7 drives the push plate 62 to move to the side close to the adjacent tooth plate 63, so that the push plate 62 and the connected tooth block 621 abut against the adjacent tooth plate 63, making it difficult for the traverse block 4 to continue to move, thereby limiting the position of the traverse block 4 and the grinding device connected to the traverse block 4.

[0046] The push plate 62 is connected to an auxiliary positioning member 64 , and the auxiliary positioning member 64 is used to further strengthen the abutment state between the push plate 62 and the tooth plate 63 .

[0047] By providing the auxiliary positioning member 64 , the relationship between the push plate 62 and the tooth plate 63 can be made more stable, thereby providing a more stable limiting effect for the transverse movement block 4 .

[0048] The auxiliary positioning member 64 includes auxiliary rods 641 connected to two opposite side walls of the push plate 62. Each auxiliary rod 641 is set at an acute angle to the side wall of the connected push plate 62, and when the push plate 62 abuts against the adjacent tooth plate 63, the end of the auxiliary rod 641 connected to the push plate 62 away from the connected push plate 62 also abuts against the tooth plate 63.

[0049] By providing the auxiliary rod 641 , which is arranged at an angle with the side wall of the push plate 62 to which it is connected and abuts against the tooth plate 63 , the position of the transverse movement block 4 can be made more stable.

[0050] The driving assembly 7 includes a driving gear 71 fixedly connected to the universal joint 31, and driven gears 72 are meshed on both sides of the driving gear 71. Each driven gear 72 is differentially arranged with the driving gear 71, and the speed of the driven gear 72 is set faster than the speed of the meshed driving gear 71. A driving screw 73 is fixedly connected to the side of each driven gear 72 away from the traverse motor 2, and each driving screw 73 is arranged parallel to the traverse screw 3.

[0051] Each driving screw 73 penetrates the traverse block 4 along its length direction and is slidably connected to the traverse block 4. The portion of each driving screw 73 located in the traverse block 4 is threadedly sleeved with a driving block 74, and a driving rack 75 is fixedly connected to the side of each driving block 74 away from the traverse motor 2, and each driving rack 75 is meshed with a follower gear 76.

[0052] Each follower gear 76 is penetrated and threaded with a working screw 77, and each working screw 77 is vertically arranged with the adjacent driving screw 73. One end of each working screw 77 away from the follower gear 76 penetrates the adjacent side wall of the traverse block 4 and is inserted into the adjacent lock box 61, and each working screw 77 is slidably connected with the side wall of the traverse block 4 along the length direction of the connected driving rack 75.

[0053] Each end of the working lead screw 77 inserted into the lock box 61 is fixedly connected to a push block 78, each push block 78 is slidably connected to the inner wall of the lock box 61, and the side of each push block 78 away from the connected working lead screw 77 is in contact with the adjacent push plate 62. The side of each push block 78 in contact with the adjacent push plate 62 is set to be inclined from the side close to the push plate 62 to the side away from the push plate 62 and gradually away from the traverse motor 2. A plurality of compression springs 79 are fixedly connected between the side of each push block 78 close to the connected working lead screw 77 and the inner wall of the opposite lock box 61.

[0054] In actual use, when the traverse motor 2 rotates, the traverse motor 2 drives the traverse screw 3 and the driving gear 71 to rotate through the reducer 21. The driving gear 71 drives the driven gear 72 to rotate during the rotation process, and the driven gear 72 drives the driving screw 73 to rotate during the rotation process. Due to the differential setting of the driving gear 71 and the driven gear 72, the rotation speed of the driving screw 73 is faster than the rotation speed of the traverse screw 3, so that the driving block 74 can move relative to the traverse block 4.

[0055] A tension spring 622 is fixedly connected between the side of the push plate 62 away from the tooth block 621 and the inner wall of the opposite lock box 61 .

[0056] The driving block 74 drives the driving rack 75 to move during the movement, and the driving rack 75 drives the follower gear 76 to rotate during the movement. The follower gear 76 drives the working screw 77 and the push block 78 to move toward the direction close to the transverse block 4 during the rotation, so that the push plate 62 can move to the side away from the tooth plate 63 under the drive of the tension spring 622, and then the transverse block 4 can move under the drive of the transverse screw 3.

[0057] When the traverse motor 2 is not turned on, the compression spring 79 connected to the push block 78 drives the push block 78 to move away from the traverse block 4, thereby pushing the push plate 62 to move toward the side close to the adjacent toothed plate 63 and abut against the toothed plate 63. The push block 78 drives the follower gear 76 to rotate during the movement, and the follower gear 76 moves away from the driving block 74 during the rotation, so that the push block 78 drives the push plate 62 through the inclined surface, and then the push plate 62 can abut against the toothed plate 63.

[0058] The implementation principle of Example 2 is: during the rotation of the output shaft of the transverse motor 2, the transverse motor 2 drives the push block 78 to move toward the direction close to the transverse block 4, so that the push plate 62 moves toward the direction close to the transverse block 4 under the drive of the tension spring 622, so that the transverse block 4 can move under the drive of the transverse screw 3.

[0059] When the output shaft of the transverse motor 2 stops rotating, the compression spring 79 drives the push block 78 to move, so that the push block 78 can push the push plate 62 to abut against the adjacent tooth plate 63, thereby limiting the position of the transverse block 4.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
