Semiautomatic paying-off device

Abstract

The invention discloses a semiautomatic paying-off device. The semiautomatic paying-off device comprises a support bracket and a plurality of paying-off shaft brackets, wherein each paying-off shaft bracket is arranged on the support bracket through a rotating component; and the rotating axial lines of the paying-off shafts are arranged in an inclined way relative to the vertical direction. The semiautomatic paying-off device has the advantages that: the semiautomatic paying-off device has high paying-off stability, low laying difficulties and labor-saving operation, is not easy to pull down,can lay a plurality of wires at the same time, avoids bending, un-straight and cross-dislocation phenomena when wires are laid and the like.

Description

technical field [0001] The invention relates to the field of pay-off tools, in particular to a semi-automatic pay-off device for laying wires, cables and other laying objects. Background technique [0002] The ordinary pay-off device is composed of a pay-off shaft and a tripod support frame. Its disadvantages are as follows: 1. The pay-off shaft of the ordinary pay-off device is perpendicular to the support frame. If there are wires on the pay-off shaft, The force direction is also perpendicular to the supporting frame, which is easy to pull down the supporting frame; 2. When laying with an ordinary pay-off device, since the actual traction direction is not perpendicular to the direction of the rotation axis of the pay-off shaft, this requires a large force To pull the pay-off shaft to rotate, and the support frame is more likely to be pulled down, causing the wire to be damaged, or even unable to pull the pay-off shaft to rotate. In actual use, it is often necessary to incr...

[0002] The ordinary pay-off device is composed of a pay-off shaft and a tripod support frame. Its disadvantages are as follows: 1. The pay-off shaft of the ordinary pay-off device is perpendicular to the support frame. If there are wires on the pay-off shaft, The force direction is also perpendicular to the supporting frame, which is easy to pull down the supporting frame; 2. When laying with an ordinary pay-off device, since the actual traction direction is not perpendicular to the direction of the rotation axis of the pay-off shaft, this requires a large force To pull the pay-off shaft to rotate, and the support frame is more likely to be pulled down, causing the wire to be damaged, or even unable to pull the pay-off shaft to rotate. In actual use, it is often necessary to increase personnel to operate beside the pay-off device; The line device uses a single pay-off shaft, and only one roll of wire can be laid at a time. If three rolls or more of wire are laid at the same time, a corresponding number of pay-off devices will be added. Phenomena such as straight and cross misalignment increase the difficulty of laying wires, and if the wires are not straight or the crosses are not straightened out, the wires may scrape the burrs in the steel pipe, causing the wires to break, and there is a danger of leakage and short circuit when the wires are electrified.
