Description

Technical Field

[0001] The invention belongs to the technical field of power component protection equipment, and in particular relates to an insulating pull rod anti-twist-off clamp. Background Art

[0002] As time passes during the operation of the line, the insulation performance of the composite insulation string of the line will deteriorate, and it will age and generate heat. It can no longer meet the use requirements during operation, which seriously affects the safe and stable operation of the line. This type of defect is a critical defect, and it is often a tight deadline and a heavy task. In the past, the replacement of composite insulator strings involved work procedures such as wire lifting. During the operation, an insulating pull rod was required as a lifting load-bearing tool. During use, it was found that the insulating pull rod rotated along the shaft during the tightening of the screw. When the rotation reached a certain stroke, the insulating pull rod would disengage and cause the wire to fall off. At present, there are no effective preventive measures for the existing insulating pull rods. When this happens, one person needs to hold the insulating pull rod to prevent twisting, and use a drone to observe the connection of the insulating pull rod. The whole process is time-consuming and laborious. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and to solve the problems raised in the above technical background.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: an insulating pull rod anti-twist-off clamp, which includes a main frame, the main frame is clamped on the outside of the first insulating pull rod and the second insulating pull rod, a connecting head is arranged between the first insulating pull rod and the second insulating pull rod, the main frame includes an upper wire clamp and a lower wire clamp, locking mechanisms are arranged inside the upper wire clamp and the lower wire clamp, the lower wire clamp is clamped on one end of the second insulating pull rod close to the connecting head, a lower hinge seat is arranged on the side of the lower wire clamp, an anti-slip connecting rod is arranged inside the lower hinge seat, the anti-slip connecting rod is hinged to the lower hinge seat through a hinge shaft, the upper clamp seat is clamped on one end of the first insulating pull rod close to the connecting head, an upper clamp seat is arranged on the side of the upper wire clamp, a threaded section is arranged on the upper part of the anti-slip connecting rod, and a positioning rotary sleeve is screwed on the outer side of the threaded section.

[0005] The positions of the lower hinge seat and the upper clamping seat correspond to each other, and the anti-drop connecting rod can be clamped inside the upper clamping seat.

[0006] Picks are symmetrically and fixedly arranged on the outer side of the positioning rotary sleeve.

[0007] An anti-slipping head is arranged at the upper end of the threaded section, and the diameter of the anti-slipping head is larger than the inner diameter of the positioning rotary sleeve.

[0008] The locking mechanism includes a locking frame and a clamping claw, wherein brackets are fixedly provided on both the front and rear sides of the locking frame, and clamping claws are provided on the outer sides of the two brackets, a driven rod is hingedly provided between the outer end of the bracket and the middle part of the clamping claw, an active rod is hingedly provided between the middle part of the bracket and the outer end of the clamping claw, the active rod is hinged to the bracket through a connecting shaft, a driving gear is fixedly provided on the outer side of the connecting shaft, a driving rack is meshed between the two driving gears, a screw sleeve is provided in the middle part of the locking frame, a rack screw is threadedly provided inside the screw sleeve, and the rack screw is connected to the driving rack through a connecting bearing.

[0013] The present invention provides an insulating pull rod anti-twist-off clamp, which has the following beneficial effects: The device is connected to the outside of the first insulating pull rod and the second insulating pull rod through the main frame, and is equipped with a locking mechanism in the upper wire clamp and the lower wire clamp, which ensures the stable connection of the connector between the first insulating pull rod and the second insulating pull rod. The present invention can prevent the pull rod from loosening or falling off due to external force or improper operation, thereby enhancing the stability and safety of the entire structure; the design of the anti-detachment connecting rod and its cooperation with the upper clamping seat and the lower hinge seat effectively prevent the first insulating pull rod and the second insulating pull rod from twisting or accidentally detaching when subjected to force. In particular, the threaded connection between the threaded section on the upper part of the anti-detachment connecting rod and the positioning rotary sleeve, as well as the existence of the anti-detachment head, further enhances the stability of the connection, so that the clamp can maintain its functionality even in complex environments; the design of the locking mechanism enables the clamp to easily clamp the insulating pull rod and adjust the clamping force by rotating the rack screw. The setting of the grip and the handle, as well as the anti-slip pattern on the handle surface, make the operation more convenient and comfortable.

[0014] The present invention is applicable to insulating pull rods of different specifications and sizes, and can achieve stable clamping of insulating pull rods of different diameters by adjusting the clamping claws and other components in the locking mechanism, so that the present invention has wide applicability and can meet the needs of different scenarios.
