Device for replacing worn carbon slide plate of pantograph

Abstract

The invention discloses a device for replacing a worn carbon slide plate of a pantograph. The device comprises a base, the device is moved to the position below the pantograph where a carbon slide strip needs to be replaced, the carbon slide strip on the pantograph is placed in the middle of a supporting rod, one end of an air cylinder in a fixing block is connected with a top plate through a hinge base, and then a driving part works; a motor drives a first lead screw shaft, a first gear on the first lead screw shaft drives a chain to be in linkage with a second lead screw shaft, threads on the outer rings of the lead screw shafts act on a threaded ring, and therefore a pressing plate on the outer ring of the threaded ring slides to the position above the carbon slide strip in a first sliding groove, and the carbon slide strip is clamped through interaction of the pressing plate and the top plate; at the moment, the rotating end of a pneumatic wrench penetrates through a through hole in the top of the supporting rod to disassemble and replace a bolt below the carbon slide strip by driving an electric telescopic rod in a disassembling part to push, so that the carbon slide strip is replaced, and the replacement is quicker and more accurate.

Description

technical field [0001] The invention relates to the technical field of carbon slide plate replacement equipment, in particular to a pantograph worn carbon slide plate replacement device. Background technique [0002] The pantograph carbon skateboard is an important part that provides power for electric locomotives such as high-speed trains, bullet trains, passenger and freight trains, subways and light rails. Its main function is: the electric locomotive directly rubs and contacts with the catenary wire through the pantograph carbon skateboard installed on the front of the locomotive received electricity. When different types of electric locomotives run in high, medium and low speed ranges, the carbon slides of the pantograph will have electrical and mechanical impacts with the catenary wires, resulting in wear of the carbon slides of the pantograph. Therefore, the pantograph carbon slide plate has become the most frequently replaced and consumed part in the electric locomo...

AI Technical Summary

Problems solved by technology

The carbon slides of the pantograph need to be replaced regularly. The existing replacements are all manual operations. With the cooperation of two staff members, the connecting bolts on the two carbon slides on one pantograph are unscrewed and two new carbon slides are replaced. Then tighten the bolts and replace them manually, which requires a lot of manpower to participate in train maintenance, and the efficiency of manual replacement is low, and the replacement takes a long time. For this reason, we propose a replacement device for carbon skateboards worn by pantographs. to solve the above problems
