A high-precision detection device for rail transit pantographs

Abstract

The invention relates to the field of rail traffic equipment, in particular to a high-accuracy detection device for a rail traffic pantograph. The device comprises a control box, an abrasion detectionmechanism and a pressure detection device, wherein the abrasion detection mechanism and the pressure detection device are arranged between two carbon sliding plates of the pantograph; the abrasion detection mechanism comprises a lateral power device and an insulation shell; the insulation shell is arranged on the output end of the lateral power device through a shifting motor; a laser generator and a collection camera are arranged in the insulation shell; the outer side of the insulation shell is provided with a dust removal air faucet; the pressure detection mechanism comprises a contact rod, two clamping arms and three elastic elements, wherein the contact rod is connected with the movable ends of all elastic elements; a pressure sensor is arranged in one elastic element; the two clamping arms are symmetrically arranged in front of the contact rod; and the lateral power device and all elastic elements all can carry out vertical movement through one lead screw lifting element. When the device disclosed by the invention carries out abradability detection on the carbon sliding plate, the device also can synchronously detect contact force between the carbon sliding plate and an overhead line, and dust is removed from the carbon sliding plate to improve detection quality.

Description

technical field [0001] The invention relates to the field of rail transit equipment, in particular to a high-precision detection device of a rail transit pantograph. Background technique [0002] The pantograph is an important current-receiving electrical equipment for electric traction locomotives to obtain electrical energy from the catenary, and is installed on the roof of the locomotive or motor vehicle. During the running of the train, the electrical wear and sliding wear of the pantograph carbon sliding plate due to contact with the catenary wires are inevitable. Temporary power outages, etc., may cause safety accidents. [0003] At present, the detection methods of the wear state of the pantograph mainly include the static manual detection method, which is slow in efficiency and depends on the actual experience of the operator. The problem of excessive loss is caused by the excessive contact pressure of the catenary. This is because the contact force between the cat...

Problems solved by technology

[0007] The disadvantages of the above scheme are: the structure is relatively complex, the whole machine is too large, the installation is inconvenient, and it cannot be carried out simultaneously with the carbon slide wear detection work, which reduces the timeliness of the locomotive
