Description

A low-voltage plastic wire spreader

technical field

The utility model relates to the technical field of electric power construction equipment, in particular to a low-voltage plastic wire spreader.

Background technique

During the construction and laying-out process of the middle and lower household lines in the distribution network, the construction personnel must use their own arm strength to spread out the wires. It is time-consuming and labor-intensive in the process of unwinding the wires. The wire coils are easily deformed due to gravity and friction during the unwinding process, and they are twisted together. It is necessary for the construction personnel to constantly adjust the position of the wire coils to ensure smooth wire release. The workload has increased significantly. Moreover, the manual setting-out is not straight, and there is an error in estimating the length of the wire material, resulting in unnecessary waste. Manual laying-out may also cause deformation and damage to the wires. The low-voltage lines erected in this way are not beautiful and may cause wire heating faults in future operation and maintenance. Currently, squirrel-cage wire spreaders are used on site. It is mainly composed of the main shaft and the baffles on both sides. The main shaft is a cylinder, and the baffle is a wooden or metal baffle. There is a bracket to support the spreader in the air. There is a hand-operated device on the outside of the baffle that is directly connected to the main shaft. By shaking the hand-operated device, the main shaft rotates, and the wire can be wound in advance. onto the spindle. When the wire is to be used on site, grab the wire and stretch it, the main shaft rotates, and the wire is released. It is time-consuming, labor-intensive and inefficient to set out wires manually, and it is easy to cause deformation of the wires. The existing wire spreader is relatively large in volume and cannot be disassembled, which makes it very inconvenient to carry, and it is time-consuming and labor-intensive to roll the wires to be used on the cylinder in advance. Since the spindle bearings can slide, the wire will slide and fall under the force of gravity. In the process of pulling the wire, due to the effect of inertia, the unwinding cannot be stopped immediately, and human control is required. Therefore, an employee is required to control the pay-off device, resulting in a waste of personnel.
