Abstract

The invention discloses a torsion spring. The torsion spring comprises an energy storage assembly and a rotating assembly, wherein the energy storage assembly is in transmission fit with the rotating assembly, the energy storage assembly comprises a closed cylinder barrel and a piston rod, a piston is arranged in the cylinder barrel, the piston is in sealing fit with the inner wall of the cylinder barrel, the piston is fixedly connected with one end of the piston rod, and the other end of the piston rod penetrates through the cylinder barrel and then is fixedly connected with a rack; and the rotating assembly comprises a rotating shaft and a cylindrical gear, the cylindrical gear is fixedly arranged on the rotating shaft, and the cylindrical gear is meshed with the rack. The twisted rope winding drum assisting in winding up comprises the torsion spring, a rotating drum and a twisted rope wound on the rotating drum, wherein one end of a rotating shaft of the rotating drum is in transmission fit with a main power output device, and the other end of the rotating shaft of the rotating drum is in transmission fit with the cylindrical gear. The torsion of the torsion spring in the design is adjustable; installing and debugging are easy; and the torsion spring provides a winding-up assisting function for the twisted rope winding drum, so that the power requirement for a motor can be reduced.

Description

technical field [0001] The invention relates to an auxiliary hoisting device, in particular to a torsion spring and a twisted rope reel for auxiliary hoisting, which is particularly suitable for reducing the power demand of a marine twisted rope reel for a motor. Background technique [0002] Torsion springs can store and release rotational energy. When components rotate around the center, torsion springs can generate torque, prompting components to generate corresponding rotational torque, and are widely used in the field of mechanical engineering. [0003] This design is aimed at a special marine twisted rope reel, and it is expected that the torsion spring can play a certain role in auxiliary winding during the rope twisting process, so as to reduce the power demand for the motor. However, the conventional torsion spring needs to generate a large torsion force in the process of assisting the winding up. If the traditional torsion spring is used, the structure, size and we...
