A comprehensive test bench for collector shoes

Abstract

The invention discloses a comprehensive test platform for collector shoes. The comprehensive test platform for collector shoes includes a test platform frame, a fixing mechanism and a detection mechanism. The fixing mechanism is fixedly connected to one side of the upper outer surface of the test platform frame. The detection mechanism is arranged on the other side of the upper outer surface of the test bench frame, and the fixing mechanism includes a hand wheel, a screw, a screw fixing seat, a sleeve, a connecting rod, a connecting plate and a fixing plate. The mechanism includes a column, a force measuring pressure head, a cylinder and a displacement sensor. The invention not only reduces the cost of different equipment and saves space, but also saves the moving time of workpieces and the time cost and manufacturing cost of moving tools in the maintenance process due to the combination of stations. It can measure the static contact force of the collector shoe, the height of the lifting shoe and the arm shaft, automatically collect the test data of the collector shoe and form a test report, etc., realizing intelligent management.

Description

technical field [0001] The invention relates to the technical field of collector shoe testing, in particular to a comprehensive test platform for collector shoes. Background technique [0002] In the maintenance work of the subway, the maintenance and adjustment of the collector shoe is a very important part. There are many and complicated technical parameters to be controlled, including the air tightness inspection of the collector shoe cylinder, the lifting of the current receiving arm , lowering shoe height, contact force test at working height, and drawing of force and displacement curves. In the current operation process, the height of the lifting shoe in the maintenance workshop is measured manually with a height gauge, and the contact stress is measured with a spring balance. The reading is not accurate enough and is easily disturbed by human factors. In addition to the defect that the displacement and pressure curve cannot be drawn, it is impossible to realize the co...

[0002] In the maintenance work of the subway, the maintenance and adjustment of the collector shoe is a very important part. There are many and complicated technical parameters to be controlled, including the air tightness inspection of the collector shoe cylinder, the lifting of the current receiving arm , lowering shoe height, contact force test at working height, and drawing of force and displacement curves. In the current operation process, the height of the lifting shoe in the maintenance workshop is measured manually with a height gauge, and the contact stress is measured with a spring balance. The readings are not accurate enough and are easily disturbed by human factors. In addition, the displacement and pressure curves cannot be drawn, and the comprehensive detection of the performance of the collector shoe cannot be realized.

In addition, to test the air tightness of the collector shoe cylinder, another equipment is required for testing, which is costly and low in efficiency. There is no personnel control measures on site, and intelligent management cannot be carried out.
