In the process of laying out construction, the traditional method is to use manpower to pull the wires for laying out, especially for long cables, it often requires a lot of temporary labor, the demand for personnel is large, and it takes a lot of time. At the same time, temporary labor Most of them are non-electric power professionals, which can easily cause construction workers to step on the cables, increase the safety hazards of the cable system, and put a lot of pressure on safety and monitoring. At the same time, the cost is also high, which is time-consuming, labor-intensive, and low-efficiency. shortcoming

Embodiment
[0033]The bottom plate 1 is moved to the place where construction needs to be carried out by the roller 40, the handle is pulled by hand, the cable reel is placed on the hanging rod group 35, the hanging rod group 35 is socketed with the hanging bracket 33 through the hanging ring 34, so that the hanging rod group 35 moves under the effect of handle 36 along the direction of hanging ring 34, conveniently connects the cable coil on the pull rod 12 by hanging rod group 35 or takes off the cable drum from the pull rod 12; After the pull rod 12 is installed, manually rotate the wheel 30, the wheel 30 and the linkage mechanism 14 rotate simultaneously through the main shaft 29, and cooperate with the rectangular slider 11 through the linkage mechanism 14, so that all the rectangle sliders 11 are in the sliding groove 10 at the same time. Slide the same distance inside to make the combination of the pull rods 12 connected by the rectangular slider 11, replacing the traditional cylind...

The invention discloses a power line construction wire drawing device which comprises a bottom plate, a main bracket, a fixation seat, a sliding frame and a guide frame. One side of the top end of the main bracket is connected with a flange plate through a bolt. The main bracket is provided with a wire drawing motor through the flange plate. One end of the wire drawing motor is connected with a drive shaft through a rotating shaft. A wire drawing disc is arranged on the top end of the drive shaft. Four sliding grooves are uniformly arranged around one side of the wire drawing disc. Rectangular sliders which match the sliding grooves are arranged in the sliding grooves. A wire drawing rod is vertically arranged on the outer side of each rectangular slider. A rotary seat is arranged at the center of one side of the wire drawing disc. According to the invention, the wire drawing motor is used to drive the wire drawing disc to rotate through the drive shaft; a cable is released at a uniform speed; manpower pulling is replaced; the construction efficiency is improved; the labor cost is reduced; the height of a wire drawing lever is controlled by an electromagnetic switch; the position of a cable tray is controlled by the hook structure of the wire drawing lever; and a rod group can conveniently wind the cable tray on the wire drawing rods or take the cable tray from the wire drawing rods.
Description
technical field [0001] The invention relates to the technical field of electric power construction equipment, in particular to a wire pulling device for power line construction. Background technique [0002] Power cables, cables for the transmission and distribution of electrical energy. It is 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. In power lines, the proportion of cables is gradually increasing. Power cables are cable products used to transmit and distribute high-power electric energy in the main line of the power system, including 1-500KV and above various voltage levels and various insulated power cables. [0003] At present, in the process of erecting communication cables and power lines, it is necessary to remove the cables from the cable winch for setting-out construction. In the process of laying out construct...
