Problems solved by technology

[0003] The first-line system of high-voltage transmission tower has high tower structure, large span, and strong overall structure flexibility. It has the common characteristics of tower-like high-rise structure and long-span structure. Dynamic collapse and damage; meteorological conditions play a decisive role in the design and use of the first-line system of transmission towers; traditional transmission towers are formed by overlapping angle steels, and the angle steels are connected by bolts on one side; Under the long-term action of loads such as ice load and ice load, the bolts connecting the angle steel are prone to loosening and fatigue damage, resulting in a decrease in the stiffness of the transmission tower, causing local instability of the transmission tower and the collapse of the tower, and eventually causing damage to the transmission line; method to detect the tightness of each bolt, but the number of bolts is large and the installation height is high, manual detection is troublesome, time-consuming and laborious

Abstract

According to the technical scheme, the bolt assembly for the high-voltage power transmission tower comprises a bolt and a nut which are used for fixing angle steel of the high-voltage power transmission tower, an information acquisition module is arranged on the side, facing the angle steel, of the bolt and / or the nut, the information acquisition module is extruded by the angle steel bolt assembly; the information acquisition module is for acquiring and transmitting a pressure signal, and a terminal processing module for receiving and analyzing the pressure signal is further included. The boltassembly has the beneficial effects that the pre-tightening force of the bolt is decoded into an electric signal, so that the state of the bolt assembly of the power transmission tower can be conveniently monitored on line, data can be dynamically analyzed in real time, and is convenient to analyze, monitor and collect, a historical curve can be formed, so that subsequent research on the bolt assembly can be deeper, a wireless transmission module is used, a line is simpler, the communication distance is long, and disconnection is not likely to happen.

Description

technical field [0001] The invention relates to the technical field of transmission tower bolts, in particular to a bolt assembly for a high-voltage transmission tower and an anti-loosening detection method thereof. Background technique [0002] The transmission tower is the supporting point of the overhead wire, and its structural reliability is an important factor to ensure the stability of the transmission line; the bolted connection structure is widely used in the structure of the transmission tower because of its advantages of simple disassembly, safety and reliability, etc. The single-sided connection method makes the bolt bear the action of lateral alternating load. [0003] The first-line system of high-voltage transmission tower has high tower structure, large span, and strong overall structure flexibility. It has the common characteristics of tower-like high-rise structure and long-span structure. Dynamic collapse and damage; meteorological conditions play a decis...
