Problems solved by technology
When bolts are used to connect parts, the bolts are easy to loosen under vibration, causing the connected parts to disengage. Although anti-loosening measures such as washers, cotter pins, double nuts, and stoppers can be used, nut loosening still occurs from time to time, thus Affect the stability of the tower installation, resulting in the tower can not be used normally, or even serious accidents, causing heavy losses to people's lives and property

The invention discloses a lock bolt fastening device for an electric tower, and relates to the technical field of electric tower maintenance. The lock bolt fastening device comprises a fastening frame. The fastening frame comprises two opposite limiting frames, side plates are arranged between the two end portions of the two limiting frames, and lifting frames and middle fasteners are arranged in the limiting frames and on the side plates correspondingly. Two opposite end portion fasteners are arranged at the top end of each lifting frame in a sliding mode. Two opposite clamping plates are arranged in each lifting frame in a sliding fit mode, and a traction wheel is rotationally arranged at the end, extending out of the corresponding lifting frame, of each clamping plate. A sliding sleeve is rotationally arranged on each clamping plate. Driving rollers are rotationally arranged in each lifting frame, and the peripheral side faces of the driving rollers are in sliding fit with the inner walls of the sliding sleeves. The driving rollers are in linkage with the traction wheels through the sliding sleeves. The fastening frame is controlled to ascend and descend on the peripheral side of the electric tower through ascending and descending; in the ascending and descending process of the fastening frame, the bolts on the two side faces of the electric tower are fastened through cooperation of the middle fasteners and the end portion fasteners, the situation that the bolts are loosened, and consequently the normal function of the electric tower is affected is avoided, and the life and property safety of people is guaranteed.
Description
technical field [0001] The invention belongs to the technical field of electric tower maintenance, in particular to an anti-loosening bolt fastening device for electric towers. Background technique [0002] Electric towers are trapezoidal or triangular tower-shaped buildings, usually 25-40 meters high, and are steel frame structures. Electric towers are mostly built near power plants and distribution stations in the field. It is an important facility in the power sector, which can overhead wires and play a role in protection and support. The design, manufacture, installation, maintenance and quality inspection of power towers are important guarantees for the operation and development of modern power systems. Only by continuously improving the technical level of power tower design, manufacturing, installation and maintenance, and continuously strengthening the quality inspection of power towers, can we adapt to the development of modern power standards and progress.
