The invention relates to the technical field of anti-theft bolts for a power transmission line iron tower, in particular to a detachable anti-theft bolt assembly for a power transmission line iron tower. The detachable anti-theft bolt assembly comprises a bolt, a first nut, a second nut, an adjusting block, a limiting block, a reset elastic sheet and a special wrench; the second nut is clamped into a groove through a protrusion to be arranged on the first nut in a covering mode; the adjusting block and the limiting block are installed in a cavity through a rotary shaft, the adjusting block ispressed on the limiting block, and the limiting block is pressed on the reset elastic sheet; a threaded rod of the bolt is uniformly provided with tooth-like clamping grooves, the limiting block is provided with clamping pins corresponding to the clamping grooves, and the limiting block is clamped into the clamping grooves through the clamping pins so that the bolt can be locked; and the adjustingblock is provided with a special-shaped groove, the special wrench is provided with a wrench head corresponding to the special-shaped groove, the wrench head is inserted into the special-shaped groove so that the adjusting block can be driven to rotate around the rotary shaft, accordingly, the limiting block is driven to rotate, the clamping pins are separated from the clamping grooves, and the bolt is unlocked. The detachable anti-theft bolt assembly has the anti-theft and anti-loosening functions, the bolt can be disassembled without being damaged, the overhaul operation efficiency is improved, and the cost is reduced.
Description
technical field [0001] The invention relates to the technical field of anti-theft bolts for transmission line iron towers, in particular to a detachable anti-theft bolt assembly for transmission line iron towers. Background technique [0002] Transmission line tower is a tower-shaped building for power transmission. Their structural characteristics are that all kinds of towers are space truss structures, and the rods are mainly composed of single equilateral angle steel or composite angle steel. The materials are generally Q235 (A3F) and Q345 (16Mn), and the connection between the rods is made of coarse The whole tower is composed of angle steel, connecting steel plates and bolts. Individual parts such as tower feet are welded into an assembly by several steel plates, so hot-dip galvanized anti-corrosion, transportation and construction erection are extremely convenient. [0003] In recent years, the theft of power facilities has become very serious, especially for steel to...
