Abstract

A portable temporary righting device for inclination of a power transmission line pole and tower comprises a rack, a line collecting reel is installed on one side of the rack, a rope is wound around the line collecting reel, a line clamping groove is formed in one end of the line collecting reel, and a ratchet wheel mechanism is arranged at the other end of the line collecting reel, wherein the ratchet wheel mechanism and the line collecting reel coaxially rotate. Pawls and reversing deflector rods are arranged on the rack. A guiding pulley is installed on the other side of the rack, a conical shaft and big gears are installed on the rack and rotate coaxially, and the big gears and a gear set are assembled in a meshed mode. A balance weight disc connected with the gear set is installed on the rack and connected with a pedal through a connecting rod, and the balance weight disc, the connecting rod and the pedal form a crank and rocker mechanism. The portable temporary righting device can temporarily right the pole and tower and prepare time for permanent reinforcement of the pole and tower; operation can be achieved only through manpower, and the portable temporary righting device is applied to finding inclination of the pole and tower in time and temporarily righting the pole and tower in time, and also suitable for pole and tower emergency maintenance engineering in remote mountain regions or pole and tower emergency maintenance engineering where the pole and tower in inclination can not be temporarily righted unless depending on labor.

Description

technical field [0001] The invention relates to a portable tilting temporary erecting device for a tower of a power transmission line, which belongs to the field of operation, maintenance and construction of a high-voltage power transmission and transformation project. Background technique [0002] With the continuous increase of my country's electricity demand and the rapid expansion of the grid scale, the requirements for the safe operation of transmission lines are getting higher and higher. However, in the actual operation of the transmission line, from time to time, the structure of the corner tower of the line will exceed the standard after the line is tightened, and the whole will tilt to the inner corner side, resulting in the tilt of the tower. At the same time, due to the complex areas that the line generally passes through, under the influence of long-term natural environment and external conditions, the line passes through the goaf (abandoned space after coal min...
