A track-type tension fixture

Abstract

The invention discloses a track-mounted tension string holder. A track clamp spring is fixed on the upper end face of a base plate by using a track bolt, and a lock catch bolt is arranged on the front end face of the base plate. The base plate has the structure that the left end and right end of the base plate are provided with lug plates, connecting holes are formed in the lug plates, the middle of the base plate 1 is provided with a bayonet, the left edge and right edge of the bayonet are provided with lock catch bolt fixing plates, lock catch bolt holes are formed in the lock catch bolt fixing plates, a plurality of slots are uniformly distributed in front of the upper end face of the base plate, a plurality of track bolt holes are formed in the upper end face of the base plate, the track clamp spring is a plate, a straight notch is arranged on the plate, and a plurality of clamping teeth clamped with the slots are uniformly arranged on the front end face of the plate. Compared with the prior art, the track-mounted tension string holder disclosed by the invention is suitable for various replacing tools of strain insulator strings of link fittings, solves the problem of complex tension string holders at present, and achieves the purpose of replacing different strings of tension insulators by adopting one set of tool.

Description

technical field [0001] The invention relates to a fixture for tension insulators of power transmission lines. Background technique [0002] The tension insulator jig for transmission lines is the back clamp for replacing a single string of insulators with power on. It, together with the insulation adjustment plate, the adjustment screw rod and the tension front clamp, constitutes a tightening tool system for replacing tension single-string insulators. The tension insulator fixture is assembled on the connecting hardware between the insulator string and the pole tower, and it is the link between the past and the future in the whole tightening tool system. The tension insulator strings of transmission lines have different connection fittings due to the different string types. When the maintenance unit replaces these insulators of different string types with live work, different types of tension fixtures are required, which brings great inconvenience to the operation and main...

AI Technical Summary

Problems solved by technology

When the maintenance unit replaces these insulators of different string types with live work, different types of tension fixtures are required, which brings great inconvenience to the operation and maintenance work and daily management work, especially for emergency repair work in areas with difficult traffic , due to the lack of conditions for on-site investigation, the emergency repair tools they carry often cause the maintenance personnel to return without success.
