Thread jamming device winding and unwinding operation device

Abstract

The invention discloses a thread jamming device winding and unwinding operation device which comprises a main connecting plate, a containing plate and a recycling plate. Both the containing plate and the recycling plate are fixedly connected with the main connecting plate, two connecting holes, a first pin shaft hole and a second pin shaft hole are formed in the main connecting plate, the two connecting holes are used for being connected with safety hooks, the first pin shaft hole is used for allowing an upper jaw fixing pin shaft to be inserted to enable the main connecting plate to be connected with an upper jaw of a thread jamming device, and the second pin shaft hole is used for allowing a lower jaw fixing pin shaft to be inserted to enable the main connecting plate to be connected with a lower jaw of the thread jamming device. A containing pulling ring is arranged on the end portion of one end, far away from the main connecting plate, of the containing plate, and a recycling pulling ring is arranged on the end portion of one end, far away from the main connecting plate, of the recycling plate. The thread jamming device winding and unwinding operation device has the advantages of bringing convenience to a user who uses the thread jamming device to place the thread jamming device at the appropriate thread holding position, bringing convenience to recycling the thread jamming device, being simple in structure and easy to manufacture and the like.

Description

technical field [0001] The invention relates to a retractable and retractable operating device for a wire clamp, in particular to a retractable and retractable operating device for a wire clamp for an overhead line. Background technique [0002] In the construction of the distribution network, the wire gripper is mainly used in combination with the wire tensioner to tighten the wire and adjust the sag of the overhead line. It is a commonly used wire holding tool in the construction and maintenance of the power overhead line. [0003] The main components of the wire gripper in the prior art include: a base plate 1, a connecting plate 2, a pull arm 3 and a pull ring 4, the lower jaw 5 is fixed at the lower edge of the left end of the base plate 1, and the center of the back of the upper jaw 6 passes through The pin shaft is hinged at the lower end of the connecting plate 2, the positions of the upper jaw and the lower jaw are corresponding, the upper end of the connecting plat...

AI Technical Summary

Problems solved by technology

The disadvantages of this type of wire gripper include: First, the jaws can only be opened manually, so that the wire holding position can only be within the reach of the operator, which may cause the wire to be tightened for a short distance and fail to reach the sag The design value needs to be reworked and readjusted, which reduces the operating efficiency; secondly, after the operation is completed, since the jaws can only be opened manually, when the position of the wire gripper is far away, it is difficult to open the jaws, and there may be violations of regulations by construction personnel. Potential safety hazards such as cable clamp falling off

These defects are not conducive to working at heights
