Problems solved by technology

However, the existing traditional operating frame has great disadvantages in practical applications. Its single steel pipe structure has relatively low strength and is easy to bend; it is heavy and inconvenient to operate in actual work; When carrying out maintenance operations (replacing insulators, changing single to double, replacing shock hammers, repairing drain wires, replacing fittings, etc.), the tension pole tower has a large inclination angle, no point of focus, it is not easy to control the operating position, and it is time-consuming and laborious, reducing the Safety factor
The connection points of the traditional operating frame are all welded, the safety factor is not high, the material is rigid, heavy and easy to bend

Embodiment Construction

[0015] figure 1 It shows that this 35-220kV line maintenance operation frame: a number of longitudinal tubes 3 are uniformly fixed between two aluminum alloy tubes 1 and 2 arranged horizontally, and the tube sleeve 4 is fixed to the left end of the two aluminum alloy tubes by bolts. The hook 5 is fixed on the pipe sleeve 4 by bolts, and the hanging ring 6 is hinged on the right ends of the two aluminum alloy pipes. The hanging ring 6 is hinged on the right end of the two aluminum alloy tubes 1, 2 via a split pin (see figure 2 , image 3 , Figure 4 ). A hole is made on the aluminum alloy pipe, and the hanging ring is penetrated from the hole on the aluminum alloy pipe, and a cotter pin is used to fix the cotter pin hole on the outer end of the hanging ring. The hanging ring can also adopt other existing articulation methods, for example, a rotating shaft is erected on two aluminum alloy tubes, and the hanging ring is fixed on the rotating shaft.

Abstract

The utility model relates to a 35-220kV line inspection and maintenance operating frame, which belongs to the auxiliary equipment for transmission line inspection. A 35-220kV line inspection and maintenance operation frame. There are multiple longitudinal tubes evenly distributed between two aluminum alloy tubes arranged horizontally. The tube sleeve is fixed to the left end of the two aluminum alloy tubes by bolts. Put it on, and the hanging ring is hinged on the right end of two aluminum alloy tubes. The invention has stable structure, high strength and light weight, and there are hanging points at both left and right ends, which improves the safety of working on the tension pole tower.

Description

Technical field [0001] The invention relates to a power transmission line maintenance appliance, in particular to an operating frame used in the maintenance work of a tension pole tower of a power transmission line. Background technique [0002] In the maintenance of power outages of transmission lines, the maintenance of tension poles occupies a large proportion. However, the existing traditional operation frame has great disadvantages in practical applications. Its single steel pipe structure has relatively low strength and is easy to bend; it has a large weight and is inconvenient to operate in actual work; and it has a large span and high drop. When performing maintenance work (replacement of insulators, single-to-double, replacement of anti-vibration hammers, repair of drainage lines, replacement of fittings, etc.) of the tensile tower, its tilt angle is large, there is no focus point, it is not easy to control the operating position, and it is time-consuming and labor-inten...
