Description

Technical Field

[0001] This utility model relates to the field of railway signal facility maintenance technology, and more specifically, to a railway signal facility maintenance tool. Background Technology

[0002] In emergency repairs of broken railway signal lines, a variety of repair tools are required. A ladder with hooks is a basic repair tool. It is hung on other signal lines parallel to the broken line, and then personnel climb up to a higher position to repair the faulty signal line.

[0003] Existing ladders with hooks are not very secure because the hooks are simply attached to the signal line. When the railway signal line bears the significant tension and pressure from the weight of the ladder and the workers, the ladder is prone to swaying. This can cause the ladder to slip, leading to workers falling from their positions and hindering the repair of faulty signal lines. Furthermore, if the swaying is too great, the hooks may detach from the signal line, causing a safety accident. Therefore, we propose a new tool for repairing railway signal facilities. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a railway signal facility maintenance tool to solve the technical problem of poor stability of current hook ladders.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a railway signal facility maintenance tool, including a ladder body, hooks arranged at both ends of the top of the ladder body, a mounting plate slidably arranged inside the hooks, rectangular holes symmetrically opened on the mounting plate, a clamping plate rotatably arranged inside the rectangular holes, a limit block arranged at the top center of the mounting plate, push plates rotatably arranged at the bottom of both sides of the limit block, and the top of the push plates contacting the top of the hooks, the push plates on both sides of the limit block are inverted V-shape, and a transmission frame rotatably arranged at the top of the push plate on the side of the push plate facing away from the limit block, the transmission frame being rotatably connected to the top of the clamping plate;

[0006] The clamping part is located below the clamping plate, and the connecting part is located above the clamping plate. The clamping part and the connecting part are V-shaped.

[0007] Preferably, the clamping portions of the two sets of clamping plates on the mounting plate are V-shaped, and the connecting portion is parallel to the push plate.

[0008] Preferably, the mounting plate has sleeve holes on both sides of the top, the sleeve holes are fitted onto the hooks, and several sets of symmetrical balls are rolled on all four sides of the inner wall of the sleeve holes. The hooks have mating arc grooves corresponding to the balls, and the balls are located in the mating arc grooves.

[0009] Preferably, a roller is rotatably arranged on the top of the push plate, and an elastic tension rod is arranged between the tops of the front and rear sides of the two sets of push plates.

[0010] Preferably, the elastic tension member includes a sleeve, an insert rod, and a spring. The sleeve is connected to the insert rod via the spring. The insert rod is inserted into the sleeve, and the spring is located inside the sleeve. The end of the sleeve facing away from the insert rod is rotatably connected to a set of push plates, and the end of the insert rod facing away from the sleeve is rotatably connected to another set of push plates.

[0011] Preferably, an arc-shaped groove is provided in the center of the bottom of the mounting plate, and an arc-shaped clamping block is arranged on one side of the clamping part. A rubber layer is arranged in both the arc-shaped groove and the surface of the arc-shaped clamping block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model utilizes a structure including a mounting plate, clamping plate, limiting block, push plate, and transmission frame. The push plate is arranged in an inverted V-shape. When the hook is attached to the signal line, the mounting plate first contacts the signal line. Then, under the weight of the ladder body and the user, the mounting plate moves upward within the hook. At this time, the two sets of push plates expand, and under the transmission frame, the two sets of clamping plates rotate. The two sets of clamping plates then directly clamp the signal line on both sides until the limiting block reaches the top of the hook. While the hook is being hung on the signal line, the mounting plate, along with two sets of clamping plates, provides three-point stable clamping for the signal line under its own weight. This effectively ensures the stability of the ladder body hanging on the signal line, preventing displacement, shaking, or even detachment. This greatly enhances the stability of the ladder body hanging on the signal line, facilitating maintenance of faulty signal lines and solving the technical problem of poor stability in current hook-mounted ladders. Therefore, this invention offers the advantage of more stable hanging.

[0014] 2. The clamping plate of this utility model has a clamping part at the bottom and a connecting part at the top. The clamping part and the connecting part are V-shaped. The clamping parts of the two sets of clamping plates are initially V-shaped, which facilitates the signal line to enter between the two sets of clamping plates. The connecting part is initially parallel to the push plate in the initial state. Therefore, in the narrow environment inside the hook, the tilting transmission range of the transmission frame can be larger, ensuring that when the push plate expands, the transmission frame can drive the clamping plate to rotate and clamp more smoothly, avoiding jamming and further improving the effect of hook hanging and fixing to the signal line.

Detailed Implementation

[0024] like Figures 1 to 7 As shown, this utility model relates to a railway signal facility maintenance tool, including a ladder body 1, with hooks 2 arranged at both ends of the top of the ladder body 1, and an installation plate 3 slidably arranged inside the hooks 2. Rectangular holes 301 are symmetrically opened on the installation plate 3, and a clamping plate 4 is rotatably arranged inside the rectangular holes 301. A limit block 5 is arranged at the top center of the installation plate 3, and push plates 6 are rotatably arranged at the bottom of both sides of the limit block 5. The top of the push plates 6 contacts the top of the hooks 2. The push plates 6 on both sides of the limit block 5 are in the shape of an inverted V. A transmission frame 7 is rotatably arranged at the top of the push plate 6 on the side facing away from the limit block 5. The transmission frame 7 is rotatably connected to the top of the clamping plate 4.

[0025] When the hook 2 on the ladder body 1 is hooked onto the signal line, the mounting plate 3 first contacts the signal line. Then, under the weight of the ladder body 1 and the weight of the user, the mounting plate 3 moves upward within the hook 2. At this time, the two sets of push plates 6 expand, and under the transmission of the transmission frame 7, the two sets of clamping plates 4 rotate. The two sets of clamping plates 4 then clamp the signal line on both sides until the limit block 5 reaches the top of the hook 2. At this time, the hook 2 is hooked onto the signal line. Under its own weight, the mounting plate 3 and the two sets of clamping plates 4 can provide a three-point stable clamping of the signal line, which can effectively ensure the stability of the ladder body 1 hooked onto the signal line. Firstly, it is not easy to shift, and secondly, it is not easy to shake or even fall off. This can greatly ensure the stability of the ladder body 1 hooked onto the signal line, making it convenient for personnel to repair faulty signal lines.

[0026] Specifically, the mounting plate 3 has sleeve holes 302 on both sides of its top, which fit onto the hook 2. Several sets of symmetrical balls 303 are rolled on all four sides of the inner wall of the sleeve hole 302. The hook 2 has a matching arc groove 201 corresponding to the balls 303, and the balls 303 are located in the matching arc groove 201. The mounting plate 3 slides on the hook 2 through the sleeve holes 302, and under the cooperation of the balls 303 and the matching arc groove 201, rolling friction is achieved, reducing the coefficient of friction and ensuring that the sliding of the mounting plate 3 is smoother.

[0027] Furthermore, a roller shaft 601 is rotatably arranged on the top of the push plate 6, and an elastic tension rod 8 is arranged between the tops of the front and rear sides of the two sets of push plates 6; the elastic tension rod 8 includes a sleeve 801, an insert rod 802, and a spring 803. The sleeve 801 is connected to the insert rod 802 through the spring 803. The insert rod 802 is inserted into the sleeve 801, and the spring 803 is located inside the sleeve 801. The end of the sleeve 801 facing away from the insert rod 802 is rotatably connected to one set of push plates 6, and the end of the insert rod 802 facing away from the sleeve 801 is rotatably connected to the other set of push plates 6; the push plate 6 contacts the top of the hook 2 through the roller shaft 601 to achieve rolling. Dynamic friction reduces the coefficient of friction, ensuring smooth expansion or contraction of the push plate 6 and preventing jamming or even getting stuck. The sleeve 801 and the insertion rod 802 can be stretched with the help of the spring 803 and can automatically reset. Therefore, when the ladder body 1 needs to be removed, during the lifting process, the weight of the ladder body 1 and the human body is lost. Under the action of the elastic tension rod 8, the mounting plate 3 and the two sets of push plates 6 can be automatically reset. At this time, the push plate 6 drives the clamping plate 4 to reset through the transmission frame 7, thereby detaching the clamping plate 4 from the signal line. The personnel can quickly remove the ladder body 1 from the signal line.

[0028] Furthermore, an arc-shaped groove 304 is provided in the center of the bottom of the mounting plate 3, and an arc-shaped clamping block 403 is arranged on one side of the clamping part 401. A rubber layer is arranged in the arc-shaped groove 304 and on the surface of the arc-shaped clamping block 403. The arc-shaped groove 304 and the arc-shaped clamping block 403 can achieve large-area contact and clamping with the signal line, which makes the clamping effect of the signal line better. Moreover, the arc-shaped groove 304 and the arc-shaped clamping block 403 can play a protective role by contacting the signal line through the rubber layer.

[0029] In the embodiment of this utility model, the clamping plate 4 has a clamping part 401 below it and a connecting part 402 above it. The clamping part 401 and the connecting part 402 are V-shaped. The clamping parts 401 of the two sets of clamping plates 4 on the mounting plate 3 are V-shaped, and the connecting part 402 is parallel to the push plate 6.

[0030] In the initial state, the two sets of clamping plates 4 clamping parts 401 are in a figure-eight shape, which facilitates the signal line to enter between the two sets of clamping plates 4. The connecting part 402 is initially parallel to the push plate 6 in the initial state. In the narrow environment inside the hook 2, the tilting transmission range of the transmission frame 7 can be larger, ensuring that when the push plate 6 expands, the transmission frame 7 can drive the clamping plate 4 to rotate and clamp more smoothly, avoiding jamming and further improving the effect of hook 2 hanging and fixing to the signal line.

[0031] Working Principle: This embodiment provides a railway signal facility maintenance tool. First, when the hook 2 on the ladder body 1 is hooked onto the signal line, the mounting plate 3 first contacts the signal line. Then, under the weight of the ladder body 1 and the weight of the human body, the mounting plate 3 will move upward within the hook 2. At this time, the two sets of push plates 6 will expand. Then, under the transmission and cooperation of the transmission frame 7, the two sets of clamping plates 4 will rotate. Then, the two sets of clamping plates 4 will directly clamp the two sides of the signal line until the limit block 5 reaches the top position inside the hook 2. At this time, the hook 2 is hooked onto the signal line. Under the cooperation of its own weight, the mounting plate 3 and the two sets of clamping plates 4 can provide three-point stable clamping of the signal line, which can effectively ensure the stability of the ladder body 1 hooked onto the signal line. First, it is not easy to shift, and second, it is not easy to shake or even fall off. This can greatly ensure the stability of the ladder body 1 hooked onto the signal line, making it convenient for personnel to repair faulty signal lines.

[0032] Secondly, the clamping part 401 of the two sets of clamping plates 4 in the initial state is in the shape of an octagon, which facilitates the signal line to enter between the two sets of clamping plates 4. The connecting part 402 is initially parallel to the push plate 6 in the initial state. In the narrow environment inside the hook 2, the tilting transmission range of the transmission frame 7 can be greater, ensuring that when the push plate 6 expands, the transmission frame 7 can drive the clamping plate 4 to rotate and clamp more smoothly, avoiding jamming and further improving the effect of hook 2 being fixed to the signal line.

[0033] Finally, the push plate 6 contacts the top of the hook 2 through the roller 601 to achieve rolling friction, reduce the coefficient of friction, ensure the smooth expansion or contraction of the push plate 6, and avoid jamming or even getting stuck. When the ladder body 1 needs to be removed, during the lifting process, the weight of the ladder body 1 and the human body is lost. Under the action of the elastic tension rod 8, the mounting plate 3 and the two sets of push plates 6 can be automatically reset. At this time, the push plate 6 drives the clamping plate 4 to reset through the transmission frame 7, thereby detaching the clamping plate 4 from the signal line, and the personnel can quickly remove the ladder body 1 from the signal line.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
