Abstract

The invention discloses an electric power-assisted traction device and a control method, and relates to the technical field of traction equipment. The traction device comprises: a frame; a traction mechanism, including a bobbin, a traction shaft and a load shaft arranged on the periphery of the bobbin, and wound around the bobbin. The bobbin, the traction shaft and the load shaft are respectively movably connected to the frame; the power motor is arranged on the frame, and is connected with the bobbin to provide traction assistance to the bobbin; the traction cable is wound around the bobbin at least once; The pressure sensor is located on the same side of the frame as the traction force of the traction cable. The measuring end of the pressure sensor is in contact with the surface of the traction shaft to obtain the pressure data when the traction shaft is compressed; wherein, the pressure sensor sends the pressure data. To the controller, the controller adjusts the working parameters of the power motor according to the pressure data to change the traction assistance to the bobbin. The present invention can solve the technical problem that the traction device in the prior art cannot provide assistance.

Description

technical field [0001] The invention relates to the technical field of traction devices, in particular to an electric power traction device and a control method. Background technique [0002] The fixed pulley is a traction and lifting mechanism widely used in the industry. Its mechanical characteristic is that it only changes the direction of the pulling force, and does not change the magnitude of the pulling force and the pulling stroke. In contrast, the movable pulley can change the traction force, but the traction stroke needs to be changed inversely. For example, to obtain twice the pulling force through a single-action pulley, the traction stroke also needs to be doubled accordingly. Manual mechanisms such as levers and inclined planes also have similar characteristics. When the manual mechanism does work, the product of force and stroke is equal to the output work. When the output work is constant, one must be reduced and the other must be enlarged accordingly. All-e...
