The invention provides a cable laying railcar, which belongs to the technical field of cable laying and includes a vehicle frame, a support frame and a guide frame. The vehicle frame is provided with grooves between two sets of wheels in the driving direction for accommodating cable drums. The support frame is installed on the vehicle frame, and the support frame is connected with the central hole of the cable drum, and the support frame is used to support and drive the cable drum to rotate; the guide frame is installed on the vehicle frame, and the guide frame is installed There are multiple guide frames with different heights for erecting cables at different heights. The cable laying rail car provided by the present invention solves the problems in the prior art that the rail car cannot accommodate large-diameter cable drums and the existing cable brackets and cable drums are inconvenient to assemble and disassemble during subway cable laying.
Description
technical field [0001] The invention belongs to the technical field of cable laying, and more specifically relates to a cable laying rail vehicle. Background technique [0002] In order to ensure the normal power supply inside the subway, cables need to be laid in the tunnels of the subway sections, and the cables are generally arranged along the extension direction of the tunnels. In order to improve the efficiency of cable wiring and reduce the labor intensity of wiring, rail cars that can move along the track in the tunnel are generally used as the carrier of cable laying equipment. However, most of the base plates of existing rail cars are located on the upper part of the wheels. Due to the height limitation of subway tunnels, the cable drums with larger diameters cannot be transported and laid by rail cars. At the same time, since the cable needs to be laid at different heights when laying the cable, and the quality of the cable is relatively heavy, it is very laboriou...
