Description
Technical Field
[0001] This utility model relates to the field of testing equipment technology, and in particular to a device for testing the clamping performance of contact wire busbar clamps. Background Technology
[0002] The overhead contact line busbar is an important component of the rigid overhead contact line, primarily used to clamp and fix the contact wire, and to carry and transmit electrical energy. The testing of overhead contact line busbars must adhere to strict standards to ensure the safe and stable operation of the railway power supply system. Among the many testing items for overhead contact line busbars, the clamping performance test is as follows: A horizontal tension perpendicular to the conductor direction is applied to one side of the dovetail groove of the busbar, causing a displacement of 2.5 mm, then unloaded. This process is repeated until the required number of tests are reached. The sample should not show cracks or plastic deformation. Currently, the busbar clamping opening test is conducted manually. Manually applying the load to one side of the dovetail groove of the busbar is prone to deviations in magnitude and direction, and the amount of displacement is difficult to control accurately, thus affecting the accuracy of the test results.

The electric cylinder 3 is fixed on the electric cylinder mounting bracket 9 in the horizontal direction and is located on one side of the busbar fixing clamp 6. The output end of the electric cylinder 3 is fixedly provided with a loading block 10. The lower end of the loading block 10 is provided with a loading protrusion 12 that can extend into the busbar clamp 11.
[0027] In use, the contact wire busbar 7 is fixedly installed using the busbar fixing clamp 6. The horizontal position of the electric cylinder 3 is adjusted by the horizontal position adjustment device 8 so that the loading protrusion 12 at the lower end of the loading block 10 is aligned with the busbar clamp 11. Then, the height of the contact wire busbar 7 and the electric cylinder 3 are adjusted in conjunction by the first lifting adjustment device 5 and the second lifting adjustment device 13 so that the loading protrusion 12 extends into the busbar clamp 11. Then, the position of the electric cylinder 3 is adjusted by the horizontal position adjustment device 8 so that the loading protrusion 12 contacts the inner side of one side of the busbar dovetail groove.

The electric cylinder mounting bracket 9 is fixedly mounted on the horizontal position adjustment slider 29. By rotating the horizontal position adjustment drive handwheel 32, the horizontal position adjustment screw nut block 30 and the horizontal position adjustment slider 29 can be driven to move linearly together, thereby driving the electric cylinder mounting bracket 9 to move and realize the adjustment of the horizontal position of the electric cylinder 3.
[0033] In this embodiment, a guide rod 33 is fixedly provided on the horizontal position adjustment fixing seat 28. The guide rod 33 is parallel to the lead screw 17.
