Description

Technical Field

[0001] This utility model relates to the technical field of railway catenary operation ladder vehicles, and more specifically, to an operation ladder vehicle for railway overhead catenary. Background Technology

[0002] A railway overhead contact line work ladder vehicle is a construction device with a ladder and a moving platform that can be moved along the railway to facilitate construction personnel to approach the overhead contact line for construction.

[0003] The existing work ladder trucks have limited range of movement when construction workers are working on top. If some areas that need to be worked on are close to one side of the work ladder truck, only the entire ladder truck can be moved. This means that the ladder truck needs to be moved multiple times when working on the same area, which affects the efficiency of construction. Utility Model Content

[0004] The purpose of this utility model is to provide a working ladder for railway overhead contact lines, which solves the problem that when working on the same area, the limited range of movement of construction personnel requires multiple moves of the entire ladder, thus affecting the efficiency of construction.

[0005] This utility model is achieved through the following technical solution:

[0007] Preferably, the movable platform slides into the groove at the top of the main body via a bottom slider.

[0008] Preferably, the limiting hole is a plurality of grooves arranged on the top of the main body, and the inner wall of the limiting hole is threaded to the side wall of the limiting rod.

[0009] Preferably, the diagonal bracing assembly includes a lifting groove, a hinge block, a pin, a deflection groove, and a support rod. The lifting groove is located near the top side wall of the main body, the hinge block is connected in the lifting groove, the pin is connected to one side of the hinge block, the deflection groove is located at the bottom of one side of the movable platform, and the support rod is connected in the deflection groove.

[0011] Preferably, the deflection groove is located at the bottom of the portion of the active platform that protrudes from the top edge of the main body.

[0012] Preferably, the two ends of the support rod are respectively hinged in the deflection groove and the hinge block, and the hinge block is in the shape of a "T" and slides in cooperation with the lifting groove.

[0013] The technical solution of this utility model has at least the following advantages and beneficial effects:

[0014] 1. The movable platform in this device can extend and move, which increases the range of motion of the top of the main body, allowing construction personnel to approach the contact wire near the main body, avoiding displacement of the whole structure and making it more flexible to use.

[0015] 2. The device is also equipped with a diagonal bracing component, which provides auxiliary support to the extended part of the movable platform by deflecting and then limiting the extension of the movable platform, making the extended part more stable. Attached Figure Description

[0020] The following is combined with Figures 1 to 3 This utility model will be described in detail.

[0021] A working ladder vehicle for railway overhead contact lines includes a main body 1, a movable platform 2 connected to the top of the main body 1, a guardrail 201 on the top of the movable platform 2, the movable platform 2 and the guardrail 201 being composed of two parts, a telescopic rod 205 connecting the two guardrails 201, a limiting hole 101 on the top of the main body 1, a limiting rod 204 connected to the top of the movable platform 2, the limiting rod 204 cooperating with the limiting hole 101, a slider 202 on the bottom of the movable platform 2, and a diagonal brace assembly connected to one side of the movable platform 2, the diagonal brace assembly swinging with the displacement of the movable platform 2.

[0022] First, the main body 1 is pushed along the railway track to the contact wire where construction needs to be carried out. Then, the construction workers climb onto the mobile platform 2 to stand at a high position to facilitate the inspection and other construction work on the contact wire. Safety is ensured by the guardrail 201.

[0023] Furthermore, the active platform 2 slides with the groove on the top of the main body 1 via the bottom slider 202, and the limiting hole 101 consists of several grooves arranged on the top of the main body 1, and the inner wall of the limiting hole 101 is threadedly matched with the side wall of the limiting rod 204.

[0024] When it is necessary to carry out construction on a location that is inaccessible on one side, the limiting rod 204 on one side of the movable platform 2 can be removed, and then the movable platform 2 can be moved to move out of the top side of the main body 1. This will extend the movable platform 2 to the top side of the main body 1, increasing the range of motion for the construction personnel. This eliminates the need to readjust the position of the main body 1 to carry out construction on some inaccessible locations. The movement of the movable platform 2 is achieved by the bottom slider 202 sliding along the groove on the top of the main body 1, making the displacement of the movable platform 2 more stable. After the movement is completed, it is fixed by the limiting rod 204. The movable platform 2 can also be stored after the construction is completed to facilitate the overall movement of the main body 1.

[0025] Furthermore, the diagonal bracing assembly includes a lifting groove 102, a hinge block 1021, a pin 1022, a deflection groove 203, and a support rod 3. The lifting groove 102 is located near the top side wall of the main body 1. The hinge block 1021 is connected to the lifting groove 102. The pin 1022 is connected to one side of the hinge block 1021. The deflection groove 203 is located at the bottom of one side of the movable platform 2. The support rod 3 is connected to the deflection groove 203. Several holes that cooperate with the pin 1022 are arranged on the side wall of the main body 1. The deflection groove 203 is located at the bottom of the part of the movable platform 2 that protrudes from the top edge of the main body 1. The two ends of the support rod 3 are respectively hinged to the deflection groove 203 and the hinge block 1021. The hinge block 1021 is in the shape of a "T" and slides with the lifting groove 102.

[0026] When the movable platform 2 moves, the deflection groove 203 drives one end of the support rod 3 to move, causing the support rod 3 to deflect and form a diagonal brace. In order for the support rod 3 to cooperate with the deflection, the other end will deflect through the hinge block 1021 and rise and fall along the lifting groove 102, so that the support rod 3 can cooperate with the deflection angle. Then, the hinge block 1021 is limited by the pin 1022, so that the support rod 3 can also be fixed, thereby providing diagonal bracing for the extended part of the movable platform 2 and making the extended part of the movable platform 2 more stable.

[0027] The following is a detailed implementation process of this utility model: First, the main body 1 is pushed along the railway track to the contact wire where construction needs to be carried out. Then, construction workers climb onto the movable platform 2 to stand at a higher position for convenient inspection and other construction work on the contact wire. Safety is ensured by the guardrail 201. When construction needs to be carried out in areas inaccessible on one side, the limiting bar 204 on one side of the movable platform 2 can be removed, and then the movable platform 2 can be moved, causing it to extend beyond the top of the main body 1. This increases the range of movement for construction workers, eliminating the need to readjust the position of the main body 1 to work on inaccessible areas. The movement of the movable platform 2 is achieved through the bottom... The slider 202 slides along the groove on the top of the main body 1, making the displacement of the movable platform 2 more stable. After the movement is completed, it is fixed by the limiting rod 204. When the movable platform 2 moves, it will drive one end of the support rod 3 to move through the deflection groove 203, so that the support rod 3 will deflect to form a diagonal brace. In order for the support rod 3 to cooperate with the deflection, the other end will deflect through the hinge block 1021 and rise and fall along the lifting groove 102, so that the support rod 3 can cooperate with the deflection angle. Then, the hinge block 1021 is limited by the pin 1022, so that the support rod 3 can also be fixed, thereby providing diagonal brace for the extended part of the movable platform 2 and making the extended part of the movable platform 2 more stable.
