Constant-force and constant-speed electric capstan

Abstract

The invention provides a constant-force and constant-speed electric capstan, belongs to the technical field of machinery and solves the problem that a conventional capstan is instable in operation. The constant-force and constant-speed electric capstan comprises an enclosure, a winding drum, a motor, a speed reducer, at least one traction drum and a differential, wherein the winding drum is arranged in the enclosure and used for winding a wire rope; the motor is provided with a motor shaft which penetrates the winding drum, and the winding drum can horizontally move on the motor shaft when the motor rotates; the speed reducer is arranged at the end, far away from the motor, of the winding drum and connected with the motor shaft; one of the traction drums is connected with the speed reducer through a connecting shaft and used for receiving the wire rope output by the winding drum, and the received wire rope is conveyed out of the enclosure; and the differential is arranged in the enclosure and connected with the speed reducer. The constant-force and constant-speed electric capstan has the advantage of being stable in operation.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to an electric winch with constant force and constant speed. Background technique [0002] The winch is a light and small lifting device that uses a drum to wind a wire rope or chain to lift or pull heavy objects. It is also a self-protection and traction device for vehicles and ships. It can be used for self-rescue and rescue in harsh environments. It is widely used in military and police , petroleum, hydrology, frontier defense, fire protection and other outdoor sports and other fields. [0003] The winch can be used alone, or it can be used as a component in machinery such as lifting, road construction and mine hoisting, and it can also be used as supporting equipment for modern electronically controlled automatic operation lines. According to the power, the winch is divided into manual, electric, hydraulic, wheel, etc. Among them, the electric winch is the most common winch, whi...

AI Technical Summary

Problems solved by technology

[0004] The existing winch is prone to serious situations such as rope pressing, disordered rope, and mutual extrusion of the steel wire rope during the wire rope retraction process, which has potential safety hazards; It will change the speed of wire rope rewinding and unwinding, resulting in poor stability when the reel rotates, thus affecting the traction of the winch, lifting work, etc.
