Description

Technical Field

[0001] The utility model provides a multi-phase line-laying device, belonging to the technical field of power tower erection auxiliary devices. Background Art

[0002] The power industry is one of the core pillars of modern society, responsible for the production, transmission and distribution of electricity. This industry covers the entire chain from power generation to end users, including thermal power generation, nuclear power generation, hydropower generation, wind power generation, solar power generation and other power generation methods. The power industry not only provides residents with electricity for daily life, but also supports the operation of many fields such as industrial production, transportation, and communications. With the development of renewable energy technology and the application of smart grids, the power industry is moving towards a more efficient, environmentally friendly and intelligent direction.

[0003] At present, after the power tower is erected, the conductor needs to be laid out. The traditional laying method is to take the wire from the spool manually, and then climb the pole every time you pass a tower and hang the wire on the pulley. Figure 1 As shown, however, workers need to climb up each pole tower to operate. Since the insulated wire itself is very heavy, it is easy to affect safety during the climbing operation. In addition, in the process of dragging the wire between each pole tower, the crops and the insulation layer of the insulated wire will be damaged and worn to varying degrees. In addition, due to the heavy weight and friction resistance of the insulated wire, the dragging between each pole tower requires the use of machinery and a large amount of manpower. The use of machinery will also cause damage to the crops, which is time-consuming and labor-intensive. Utility Model Content

[0004] The technical problem to be solved by the utility model is that it is dangerous for personnel to work at heights when laying out wires, and the dragging of wires causes damage and wear to crops and the insulation layers of the insulated wires to varying degrees, resulting in low work efficiency.

[0005] In order to solve the above problems, the utility model proposes a technical solution: a multi-phase pay-off device, comprising a base plate; a connecting frame for connecting a tractor is provided on one side of the base plate, wheels are provided on both sides of the lower middle part of the base plate, mounting boxes are respectively provided at the four lower corners of the base plate, an electric motor is provided in the mounting box, an output shaft of the motor is rotated through the outer side of the mounting box through a bearing, a winding frame is provided at the end of the output shaft of the motor, a battery box with a storage battery inside is provided on one side above the base plate, a seat is provided on the other side, and a control panel is provided on one side of the seat.

[0006] As an improvement, the two wheels are connected by a rotating shaft, and the two sides of the rotating shaft rotate through the lower parts of the two mounting plates through the bearing 2, and the two mounting plates are respectively arranged on both sides of the lower middle part of the bottom plate;

[0007] As an improvement, a hinged door is provided on one side of the installation box near the middle of the bottom plate, and a plurality of heat dissipation holes are provided on the door;

[0008] As an improvement, the winding frame includes two circular baffles, the middle parts of the two baffles are connected by a cone, and the end of the cone with a smaller diameter faces outward;

[0009] As an improvement, a hinged door 2 is provided on one side of the battery box, and a plurality of heat dissipation holes 2 are provided on the door 2;

[0010] As an improvement, the battery is connected to the control panel via electric wires, and the control panel is connected to the motor via electric wires and signal lines.

[0011] Beneficial effects of the utility model:

[0012] The use of this device can solve the outstanding contradiction of short construction period and large engineering volume during the construction window period in the power industry;

[0013] The multi-position wire-laying device can ensure personnel safety. Operators do not need to directly contact the wires, which reduces the risk of operations in complex environments.

[0014] By putting out the traction rope first and then the wire, the wire will not drag on the ground and will not come into contact with the seedlings, thus minimizing the damage and wear to the crops and the insulation layer of the insulated wire.

[0015] It greatly saves manpower and material resources, changes the traditional line-laying mode, and realizes multi-phase line-laying at the same time. With the same construction force, the work efficiency is improved several times. BRIEF DESCRIPTION OF THE DRAWINGS
