Rotating device for welding grounding wire by fixed connection with barrel body

Abstract

The invention discloses a rotating device for welding a grounding wire by fixed connection with a barrel body. The rotating device comprises a pressing plate, a conductive copper sleeve, a conductive copper shaft, a connecting bolt, a gasket, a spring collar, a disc-shaped spring, a connecting block, a clamp body, an adjusting screw rod, a nut and a tightening bolt, wherein the pressing plate covers the conductive copper sleeve; the spring collar and the disc-shaped spring are arranged between the pressing plate and the conductive copper sleeve; the pressing plate tightly presses the disc-shaped spring and the conductive copper sleeve through the tightening bolt; one side end face of the conductive copper sleeve and one side end face of the conductive copper shaft are attached to each other tightly; the connecting bolt and the conductive copper shaft are in threaded connection; the gasket is arranged between the connecting bolt and the conductive copper shaft; the clamp body and the conductive copper shaft are fixed through the connecting block; the connecting block is arranged between the conductive copper shaft and the clamp body; the adjusting screw rod is arranged on one side of the clamp body; and the nut is positioned at the bottom end of the adjusting screw rod. By the rotating device for welding the grounding wire by fixed connection with the barrel body, the safety level during welding is increased and the welding quality is guaranteed.

Description

technical field [0001] The invention relates to a device for welding the circular seam of a cylinder body of a wind power machine tower, in particular to a rotating device for welding a ground wire by being fixedly connected with the cylinder body. Background technique [0002] As an inexhaustible renewable energy, wind energy has been paid more and more attention by countries all over the world. At present, countries all over the world are vigorously developing wind power generation, striving to protect the environment and realize low-carbon life. [0003] The wind turbine tower is an important component of the wind turbine. It must support the weight of the wind rotor and the nacelle of nearly 100 tons, and bear the positive pressure and overturning moment of the wind rotor, nacelle, and tower. Therefore, it is very important to improve the quality of the longitudinal and circumferential welds of the tower. The circumferential welds of the paired butt joints of the cylind...

Problems solved by technology

The previous welding wiring device has the following disadvantages: due to the very large current during welding, generally above 600 amperes, the grounding cable will heat up and burn, and there is a fire hazard; the temporarily welded ground wire or the ground wire without a fixed connection will damage the base material; Cable twisting shortens cable life
