Description

Technical Field

[0001] This utility model relates to the field of rail transit technology, specifically to a support device for rail transit maintenance. Background Technology

[0002] As we all know, rail transit is an indispensable mode of transportation for human travel. Rail transit refers to public transportation facilities with fixed lines, fixed tracks, and equipped with transport vehicles and service facilities. Rail transit has long existed as public transportation in cities and plays an increasingly important role. The history of transportation development in economically developed countries tells us that only by adopting rail transit systems can we fundamentally improve the national transportation situation. Rail transit is the lifeline of my country's national economy and the backbone of its transportation network. It not only undertakes the transportation of most of the country's strategic and economic materials but also performs passenger transport functions. Ensuring the long-term safe operation of rail transit is a problem that must be faced and solved in the current stage of rail transit development.

[0003] The patent specification with publication number CN214362609U discloses a support device for rail transit maintenance, including a support beam, a support column assembly, a second support column assembly, a support claw assembly, a hydraulic cylinder assembly, a hydraulic rod assembly, a left gripper module, a right gripper module, a left gripper, a right gripper, an auxiliary beam, a second auxiliary beam, and a support module assembly. The support claw assembly and the support column assembly are fixedly connected. A threaded hole is provided in the middle of the bottom end of the hydraulic rod assembly. The support column assembly and the second support column assembly are rotatably connected by a rotating shaft. The outer wall of the second support column assembly is provided with threads. The second support column assembly and the hydraulic rod assembly are screwed together. The hydraulic cylinder assembly and the support module assembly are fixedly connected. Holes are provided in both the upper and lower parts of the support module assembly. The support beam and the auxiliary beam are slidably connected within the support module assembly through the holes in the lower and upper parts of the support module assembly, respectively. Holes are provided in both the lower end of the auxiliary beam and the lower end of the second auxiliary beam. It is easy to operate, has a simple structure, and provides stable support.

[0004] However, during the implementation of the relevant technology, the following problems were found in the above technical solution: In the process of using the above device, i.e. in the existing track maintenance process, if the rail is not supported and fixed, when the rail is hit by a tool, it will shake because it is not restricted by external force to prevent it from deviating. The rail is prone to deviating from the original predetermined track, so the rail needs to be moved back to the original predetermined track, which increases the workload of the staff. Therefore, further improvement is needed. Utility Model Content

[0005] This utility model proposes a support device for rail transit maintenance, which solves the problem that it is inconvenient to provide stable and convenient fixed support for the track body in related technologies.

[0006] The technical solution of this utility model is as follows:

[0007] A support device for rail transit maintenance includes a track body, a horizontal plate disposed on the top of the track body, a first support member penetrating through the upper end of one side of the horizontal plate for supporting one side of the horizontal plate, and a second support member penetrating through the upper end of the other side of the horizontal plate for supporting the other side of the horizontal plate. The first support member and the second support member have the same structure. A first fixing member is fixedly connected to the lower end of the horizontal plate, one side of the first fixing member engaging with one side of the track body. An adjustment component for engaging and fixing the other side of the track body is slidably connected to the lower end of the horizontal plate.

[0008] Preferably, the second support member includes a screw that passes through the upper end of the horizontal plate, a nut is fixedly connected to the upper end of the screw, an extension block is fixedly connected to the lower end of the screw, a placement plate is provided below the extension block, an auxiliary block is fixedly connected to the upper end of the placement plate, and the auxiliary block is hinged to the lower end of the extension block.

[0009] Preferably, the adjustment component includes a second fixing member disposed below the horizontal plate, a slider fixedly connected to the upper end of the second fixing member, a through groove through one side of the slider, a first slot formed on the side wall of one end of the through groove, a first sliding groove formed at the lower end of the horizontal plate, a second sliding groove formed on one side of the horizontal plate, a first limiting component and a second limiting component formed on the inner wall of the second sliding groove, and a circular block slidably connected through the inside of the through groove.

[0010] Preferably, one side of the second fixing member engages with one side of the track body, the first slide groove is connected to the second slide groove, and the first limiting component and the second limiting component have the same structure.

[0011] Preferably, the first limiting component includes a circular groove formed on the inner wall of the second slide groove, and the inner wall of the circular groove has an inlet groove, an annular groove and a second locking groove.

[0012] Preferably, the inlet groove is connected to the annular groove, the annular groove is connected to the second retaining groove, the circular groove is connected to the through groove, and the inlet groove is connected to the first retaining groove.

[0013] Preferably, a locking block is fixedly connected to the outer surface of the circular block, and a handle is fixedly connected to one end of the circular block.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] This invention utilizes a handle that, when pulled, causes a circular block to move a locking block into the first slot. Moving the handle then causes the slider to move along the second groove via the circular block. Simultaneously, the handle pushes the second fixing member towards the other side of the track body until the second fixing member engages with the other side of the track body. At this point, the handle moves the first slot to the groove's inlet. The handle can then be pushed to disengage the locking block from the first slot and into the groove. Rotating the handle causes the locking block to rotate along the annular groove. Pulling the handle outwards causes the locking block to enter the second slot. The locking block prevents the circular block from accidentally disengaging from the groove, thus preventing the slider from sliding again inside the first groove and preventing the second fixing member from accidentally separating from one side of the track body. This combination of the second and first fixing members effectively supports the track body, solving the problem of inconvenient and stable support for the track body. Attached Figure Description

[0024] like Figures 1-4 As shown, this embodiment proposes a support device for rail transit maintenance, including a track body 1, a horizontal plate 2 disposed above the track body 1, a first support member 3 for supporting one side of the horizontal plate 2 penetrating through the upper end of one side of the horizontal plate 2, and a second support member 4 for supporting the other side of the horizontal plate 2 penetrating through the upper end of the other side of the horizontal plate 2. The first support member 3 and the second support member 4 have the same structure. A first fixing member 5 is fixedly connected to the lower end of the horizontal plate 2, and one side of the first fixing member 5 is engaged with one side of the track body 1. An adjustment component 6 for engaging and fixing the other side of the track body 1 is slidably connected to the lower end of the horizontal plate 2.

[0025] Furthermore, the second support member 4 includes a screw 41 that passes through the upper end of the horizontal plate 2. A nut 42 is fixedly connected to the upper end of the screw 41, and an extension block 43 is fixedly connected to the lower end of the screw 41. A placement plate 45 is provided below the extension block 43. An auxiliary block 44 is fixedly connected to the upper end of the placement plate 45. The auxiliary block 44 is hinged to the lower end of the extension block 43. The placement plate 45 is used to place on the ground, and the screw 41 is used to adjust the relative height of the placement plate 45.

[0026] Furthermore, the adjustment component 6 includes a second fixing member 61 disposed below the horizontal plate 2. A slider 62 is fixedly connected to the upper end of the second fixing member 61. A through groove 621 is provided through one side of the slider 62. A first locking groove 622 is provided on the side wall of one end of the through groove 621. A first sliding groove 63 is provided at the lower end of the horizontal plate 2. A second sliding groove 64 is provided on one side of the horizontal plate 2. A first limiting component 65 and a second limiting component 66 are provided on the inner wall of the second sliding groove 64. A round block 67 is slidably connected through the inside of the through groove 621. One side of the second fixing member 61 is engaged with one side of the track body 1. The first sliding groove 63 is connected to the second sliding groove 64. The first limiting component 65 and the second limiting component 66 have the same structure. The first locking groove 622 is used to place the locking block 672 in the round block 67. The first sliding groove 63 is used to place the slider 62.

[0027] Furthermore, the first limiting component 65 includes a circular groove 651 formed on the inner wall of the second slide groove 64. The inner wall of the circular groove 651 is provided with an inlet groove 652, an annular groove 653 and a second locking groove 654. The inlet groove 652 is connected to the annular groove 653, the annular groove 653 is connected to the second locking groove 654, the circular groove 651 is connected to the through groove 621, and the inlet groove 652 is connected to the first locking groove 622. The annular groove 653 is used to limit the locking block 672 and prevent the circular block 67 from leaving the interior of the circular groove 651.

[0028] Furthermore, a locking block 672 is fixedly connected to the outer surface of the circular block 67, and a handle 671 is fixedly connected to one end of the circular block 67. The handle 671 passes through the interior of the circular groove 651 and is located on the outside of the horizontal plate 2. The locking block 672 is slidably engaged with the first locking groove 622, slidably engaged with the inlet groove 652, rotatably engaged with the annular groove 653, and slidably engaged with the second locking groove 654. The handle 671 is used to move the slider 62 inside the first sliding groove 63 from the outside.

[0029] The working principle and usage instructions of this utility model are as follows: When it is necessary to perform fixed support work before maintenance of the track body 1, the staff first needs to align the first fixing part 5 with one side of the track body 1 and engage it. Then, by rotating the nut 42, the placement plate 45 is pushed to the ground. When the ground is tilted, because the auxiliary block 44 and the extension block 43 are hinged, the screw 41 can still be in a vertical state with the first fixing part 5 when the placement plate 45 is tilted to the ground. Then, the same operation is performed on the first support part 3 so that the horizontal plate 2 is stable above the track body 1.

[0030] Next, pulling handle 671 causes block 672 to move into the first slot 622 via round block 67. At this time, moving handle 671 causes slider 62 to move along the second groove 64 via round block 67. During the movement of handle 671, the second fixing member 61 is pushed towards the other side of the track body 1 until the second fixing member 61 and the other side of the track body 1 are engaged. At this time, handle 671 will move the first slot 622 to the position where it is attached to the inlet slot 652. Then, handle 671 can be pushed to disengage block 672 from the first slot 622 via round block 67. The first slot 622 enters the groove 652. Then, the handle 671 is rotated to make the block 672 rotate along the annular groove 653. Then, the handle 671 is pulled outward to make the block 672 enter the second slot 654. At this time, under the action of the block 672, the round block 67 can be prevented from accidentally leaving the inside of the round groove 651, that is, the slider 62 is prevented from sliding inside the first sliding groove 63 again, that is, the second fixing member 61 is prevented from accidentally separating from one side of the track body 1. Thus, the second fixing member 61 and the first fixing member 5 cooperate to form an effective fixed support for the track body 1.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
