Background technique

Power cables are cables used to transmit and distribute electric energy. They are often used in urban underground power grids, outgoing lines of power stations, internal power supply of industrial and mining enterprises, and underwater transmission lines across rivers and seas. The main work of the power system is to erect or lay various power supply lines and ensure the normal power supply of each power supply line. The power supply line is mainly composed of various power control equipment connected by various power supply cables. No matter what kind of cable is used, when erecting or laying the cable, the cable is generally paid out from the direction of the cable reel.

Usually, cables are routed through underground pipes, and signal and power channels are constructed by penetrating cables in underground pipes. At present, the cable is injected into the underground pipe from the pay-off reel mainly by manual method, or the cable is retracted on the pay-off reel, and the cable is usually released slowly from the pay-off reel manually, and inserted into a In the vertical well that has been drilled, use gravity to insert the cable into the underground pipeline, and then use the manual dragging method to guide the cable into the underground pipeline. The labor intensity is high, labor-intensive and time-consuming, and the work efficiency is low.

There are rotating shafts on both sides of the wire roller and the pay-off roller, and the rotating shafts are matched with the support grooves; more than two sets of positioning holes are arranged on the mounting plate and the bracket, and limit blocks are arranged in the positioning holes; A storage battery is arranged, and a small motor is arranged on the guide car, and the small motor is connected with the guide wheels through a small gear box.

Further, a connecting rod is hinged on one side of the bracket, and a hook is provided at the front end of the connecting rod.

Further, moving wheels are provided at the bottom of the base.

Further, it also includes a mobile vehicle, wheels are provided at the bottom of the mobile vehicle, and a power device is provided on the mobile vehicle.

Further, a connecting ring is provided at the bottom of the mobile vehicle.

Further, the mobile vehicle is provided with handrails.

Further, a rib plate is provided between the base and the bracket.

Compared with prior art, the beneficial effect of the present invention is:

1. The present invention cooperates with the guide vehicle and the pay-off roller to realize the automatic release, traction and retraction of the guide vehicle in the underground pipeline cable, which replaces the manual traction operation mode, greatly reduces the labor intensity of the staff, and improves the work efficiency ;

2. The up and down position adjustment of the pay-off roller can be realized through the mounting plate, which is suitable for various ground conditions and various specifications of the pay-off roller.
