With the development of industry, various pay-off racks came into being. The pay-off stand is mainly used to support the reel pay-off during line construction. When pulling the wire and the ground wire, the reel can actively roll and pay off the wire. A simple and quick wire pay-off frame includes a fixed frame, a rolling disc, a vertical shaft, a rotating shaft, a supporting disc frame and a handle. Among them, the vertical shaft of the fixed frame is fixedly connected, the rotating shaft is sleeved outside the vertical shaft, the upper part of the fixed frame is located on the outer wall of the rotating shaft, and is fixedly connected with the rolling plate, the rolling plate is parallel to the fixed frame, and the supporting plate frame is arranged on the rolling plate; Has handle.
According to the lifting method, the pay-off frame can be divided into hydraulic pay-off frame or mechanical wire pay-off frame; according to the use and structure, it can be divided into adjustable hydraulic pay-off frame, column pay-off bracket, push-rod pay-off frame and other wire pay-off frames.
Due to the different diameters of the spools, different spools usually use different pay-off racks. Therefore, there is a need for a pay-off frame that can be adjusted according to the diameter and tonnage of the spool.
At present, people are used to laying and dragging wires directly with coils. There are the following defects in:
(1) The wire is not straight, and it is easy to damage the outer sheath of the wire;
(2) Slow release line;
(3) The wires are disordered.
