Description

Tool for installing track train jumper wire Technical Field The invention relates to the technical field of manufacturing and maintenance of rail transit equipment, in particular to a tool for installing a track train jumper wire. Background In the production and manufacturing operation of rail trains, the jumper wire between the vehicles is a core component for realizing electric signal transmission and high-voltage power connection between the vehicles, and the jumper wire is generally composed of a plurality of strands of copper core cables and special connectors at two ends, the whole length is 2m-4m, the weight is 15kg-30kg, and the bending radius and interface protection of the cables are strictly required. In the current jumper working process, the following prominent problems exist due to the lack of special bearing and moving tools: 1. The jumper wire is easy to damage, oil stains and metal scraps on the ground can accelerate ageing of the insulating layer after being disassembled, the cable sheath is easy to damage and the copper core is easy to break due to the fact that a person steps on and a tool car rolls, and the connector is easy to be damaged due to the fact that no special placement position exists and the connector is easy to be impacted to cause interface deformation, stitch bending and the like. 2. The operation efficiency is low, 2-3 persons are required to carry the jumper wires by bare hands, time and effort are consumed, the cables are required to be rearranged when being arranged due to unordered stacking, and the average single operation time is more than 20 minutes. 3. The cable is subjected to fatigue damage, an adaptive support structure is not provided, the jumper wire is easy to bend excessively (exceeding the minimum bending radius requirement), the internal copper core is subjected to fatigue fracture after long-term repeated bending, and the service life of the cable is shortened by more than 30%. 4. The potential safety hazard is prominent, the jumper wires swing unordered during carrying, are easy to collide with train couplers and brake pipelines, the risk of equipment damage exists, and the jumper wires stacked on the ground are easy to trip operators. Disclosure of Invention The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the invention provides a tool for installing a track train jumper wire. In order to achieve the above purpose, the present invention adopts the following technical scheme: A frock for installation of rail train jumper wire, its base that is provided with the gyro wheel including the bottom, the base top is provided with bears the frame, it is grid bearing structure wholly to bear the frame, and its middle part is arc supporting part, the radian of arc supporting part and the natural bending radian phase-match of rail train jumper wire, the both sides level of arc supporting part is provided with puts the thing platform, the front and back both sides of putting the thing platform are provided with the handle, arc supporting part surface covering has the buffer layer.
