Temporary cross arm for replacing linear cement poles and application method thereof

Abstract

The invention discloses a temporary cross arm for replacing linear cement poles and an application method thereof. The temporary cross arm comprises a cross arm body, wherein, cement pole hold hoops are arranged on two ends of the cross arm body, and the cross arm body comprises two rigid connecting plates which are movably connected together. In the invention, the temporary cross arm is installed to stabilize and support the cement poles, thus the cement poles can still remain stable after the original cross arm is cut off so as to greatly improve the safety coefficient while the cross arm is cut off; a neutral wire is hung on a new tower and then an operator comes down from the poles for pushing over the poles; and the temporary cross arm is arranged between the two cement pole bodies so as to play the roles of stabilization and support, thus ensuring that the two pole bodies fall down towards the same direction, avoiding accidents, enhancing stability for pushing over the poles and personal safety of the operator, and greatly improving the operation safety coefficient.

Description

technical field [0001] The invention belongs to the field of replacing iron towers with straight cement poles for power construction lines, and in particular relates to a temporary cross arm for replacing straight cement poles and a use method thereof. Background technique [0002] In the construction of power lines, it is often encountered that old cement poles are replaced with iron towers. Due to the long-term field operation of the π-type cement pole of the power line, and the erosion of wind, rain, snow, fog, sun and other atmospheric factors, the main body of the pole tower is seriously aged or the original pole tower pair is crossed due to the change of crossing and crossing in the original operating channel. The cross-span distance of the spanning object is insufficient and the iron tower needs to be replaced for construction. In the construction of replacing the iron tower with a straight π-shaped cement pole, because of the rise of the iron tower on the center lin...

AI Technical Summary

Problems solved by technology

The above method is complicated to operate and needs to climb the pole multiple times; because temporary pull wires are used to stabilize the pole tower, the pole tower is prone to inclination at the moment when the crossarm is cut with the oxygen acetylene cutting handle, which causes certain risk factors for the cutting operators on the crossarm; After the mid-line lifting is completed, the disconnected cross arm needs to be connected and reinforced. The strength of the steel wire rope sleeve using the soft connection method meets the requirements, but the structure of the tower is unstable because of the soft connection method; the use of round wood binding, although the hard connection can solve the problem Solved the problem of the stability of the tower, but the strength of the round wood is difficult to meet the standard

In summary, there are certain safety hazards in this construction method.
