Description

Technical Field

[0001] The utility model relates to the technical field of rail transit, in particular to a safety regulation test bench for rail transit vehicles. Background Art

[0002] Rail transit refers to a class of transportation tools or transportation systems in which operating vehicles need to run on specific tracks. In the national standard "Common Nomenclature Terms for Urban Public Transport", urban rail transit is defined as "generally powered by electric energy and taking the wheel-rail operation mode, which is a general term for rapid mass public transport. With the diversified development of train and railway technologies, rail transit presents more and more types, which are not only spread in long-distance land transportation, but also widely used in medium- and short-distance urban public transportation.

[0003] When a rail transit vehicle is being tested, it is necessary to use a test bench to conduct insulation resistance tests, power frequency withstand voltage tests, leakage current tests, grounding resistance tests, and inter-turn withstand voltage tests. However, the existing test devices occupy a large amount of space, greatly reducing the test efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages that the existing test device occupies a large amount of space and greatly reduces the test efficiency, and to propose a safety regulation test bench for rail transit vehicles.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A safety regulation test bench for rail transit vehicles includes a test bench housing. One side of the test bench housing is open. A main door panel is hinged to one side of the test bench housing. A plurality of rectangular holes are formed inside the main door panel. An auxiliary door panel is hinged inside the rectangular holes. Two symmetrically arranged grooves are formed in the top inner wall of the test bench housing. A braking component is arranged inside the grooves. The braking component is used to brake the position of the main door panel;

[0007] A same support plate is slidably connected between the two inner walls on both sides of the test bench housing. One side of the top of the support plate is provided with a test plate for testing the rail transit vehicle. Push components are arranged on both sides of the support plate. The push components are used to push out the support plate;

[0008] Two groups of symmetrically arranged control components are arranged inside the auxiliary door panel. The control components are used to control the opening and closing of the auxiliary door panel.

[0009] In a possible design, the braking assembly includes the same top plate slidably connected between the inner walls on both sides of the groove. A same spring is fixedly connected between the top of the top plate and the inner wall of the top of the groove. One side of the bottom of the top plate is fixedly connected with a clamping plate. A clamping groove is formed in the top of the main door panel, and the clamping plate and the clamping groove are engaged with each other.

[0010] In a possible design, the pushing assembly includes two sliding grooves respectively formed in the inner walls on both sides of the test bench housing. Sliders are slidably connected inside the sliding grooves. One side of each of the two sliders close to each other is fixedly connected to both sides of the support plate. A same tension spring is fixedly connected between one side of the slider and the inner wall of one side of the sliding groove.

[0011] In a possible design, the control assembly includes a connecting rod rotatably penetrating through the inner part of the auxiliary door panel. One end of the connecting rod is fixedly connected with an operating block, and the end of the connecting rod away from the operating block is fixedly connected with a limiting block, and the limiting block is used in cooperation with the main door panel.

[0012] In a possible design, one side of the bottom of the top plate is fixedly connected with a pushing plate, and the pushing plate is used in cooperation with the limiting block.

[0013] In a possible design, support legs are fixedly connected to the four corners of the bottom of the test bench housing, and a plurality of ventilation holes are formed on both sides of the test bench housing.

[0014] In this application, when it is necessary to test a rail transit vehicle, the auxiliary door panel at an appropriate position can be opened for testing. The specific operation is as follows: rotate the operating block, the operating block drives the connecting rod to rotate, and the connecting rod drives the limiting block to rotate. When the limiting block is horizontal, the limiting block no longer abuts against the main door panel, and the auxiliary door panel can be flipped downwards, and then the test plate is used to test the rail transit;

[0015] When it is necessary to repair the internal test plate, the main door panel can be opened. The specific operation is as follows: rotate the two operating blocks above. At this time, rotate the operating blocks into a vertical state. The limiting block pushes the pushing plate to move upwards, the pushing plate drives the top plate to move upwards, the top plate drives the clamping plate to move upwards, and the clamping plate moves out of the inside of the clamping groove and compresses the spring. At this time, the braking state of the main door panel can be released;

[0016] After the main door panel is opened, at this time, the slider moves horizontally under the pulling force of the tension spring, the slider drives the support plate to move horizontally, and the support plate drives the test plate to move horizontally, so as to move the test plate to one side of the test bench housing, closer to the outside, which is convenient for the staff to repair.

[0017] Beneficial effects

[0018] In the present utility model, for the safety regulation test bench of rail transit vehicles, through the braking component, the effect of braking the main door panel can be achieved. Under normal circumstances, without opening the main door panel, only the auxiliary door panel at an appropriate position needs to be opened. When performing maintenance, the main door panel can be opened;

[0019] In the present utility model, for the safety regulation test bench of rail transit vehicles, through the pushing component, the effect of pushing the test board forward can be achieved, and then the test board is moved to one side of the test bench housing, closer to the outside, which is convenient for the staff to perform maintenance;

[0020] In the present utility model, when it is necessary to test the rail transit vehicle, the auxiliary door panel at an appropriate position can be opened for testing. When it is necessary to repair the internal test board, the main door panel can be opened, the braking of the main door panel is released through the braking component, and the support plate drives the test board to move horizontally, and then the test board is moved to one side of the test bench housing, closer to the outside, which is convenient for the staff to perform maintenance.
