Problems solved by technology

The weight of two 2-meter cross-arms is 30 kg. Due to the lack of auxiliary equipment, the time for a single operator to assemble the double cross-arms is labor-intensive, high-technical requirements, and difficult to assemble. Therefore, it is necessary to develop a double-fan The cross-arm single-person pole assembler can facilitate the single-person installation of the double-fan cross-arm, saving time and effort, and increasing the safety factor of the installation

Abstract

The invention discloses a double-cross arm assembler for a single lever. The double-cross arm assembler for the single lever comprises V-shaped connection frames, inch hoops, lifting brackets for arms, a lifting pulley, a fixing screw mechanism used for fixing the inch hoops, and a pulley fixing mechanism used for connecting the lifting pulley with the inch hoops, wherein the V-shaped connection frames comprise a frame arm I and a frame arm II, one end of the frame arm I and one end of the frame arm II are connected together to form a hinge structure by virtue of a hinge component, a loop structure I is further arranged at the common end of the frame arm I and the frame arm II; the inch hoop comprises a semicircular hoop I and a semicircular hoop II which are oppositely connected to form a loop structure; the lifting brackets for the arms are fork-shaped structures, two support arms are arranged in a splayed shape, and hooks are arranged at the independent ends of the two support arms and used for connecting pre-set holes on the same arm. By utilizing the device, one person can conveniently finish mounting work on the double-cross arm, thereby saving time and labors, and improving the security coefficient; and steps of the method in the invention are clear and easy to operate, with higher application value.

Description

technical field [0001] The invention relates to the field of electric auxiliary installation equipment, in particular to a double-fan cross-arm upper assembler suitable for installation by a single person, and also relates to an installation method. Background technique [0002] The cross arm is an iron structure fixed horizontally on the top of the utility pole. There are porcelain bottles on it to support the overhead wires. The cross arm is an important part of the pole tower. Its function is to install insulators and fittings to support wires and lightning line, and keep a certain safe distance in accordance with the regulations. [0003] With the development of urban power grids and the requirements of grid reliability, double cross-arm groups have gradually replaced the previous single cross-arm structure. According to relevant statistics, the coverage rate of double cross-arm on 10kV lines in Chongqing Municipal Power Supply Bureau has reached more than 60%, and the ...
