Description

Technical Field

[0001] The utility model relates to a traction winch, in particular to an electric and manual integrated traction winch, which is mainly used for traction of heavy objects on a horizontal ground and belongs to the technical field of winches. Background Art

[0002] Generally speaking, when pulling a heavy object horizontally, a rotating winch is usually used to tighten the wire rope to pull the heavy object to move. Existing winch devices are usually driven by a motor. Using a motor to drive the winch to rotate and tighten the wire rope has the advantages of saving effort and continuous operation. However, since some work environments are not convenient for external power supply, and the repair or purchase replacement cycle is long when the motor is damaged, there is a need for a device that can use both a motor to drive the winch to rotate and tighten the wire rope, and a hand-driven winch to rotate and tighten the wire rope. In the event that the motor is damaged or an external power supply cannot be connected, the winch can be manually rotated to complete the pulling of the heavy object.

[0003] A search revealed a Chinese utility model patent with the publication number CN217025156U, which discloses a dual-purpose electric and manual winch. The winch comprises a workbench with support legs at its lower portion. A base is connected to one side of the upper end of the workbench, with a motor mounted on the upper portion of one end of the base. A reducer is connected to one end of the motor, and a sleeve is fixedly connected to the output end of the reducer. A retractable winding mechanism is mounted on the other side of the upper end of the workbench, with a manual mechanism connected to the winding mechanism. A socket mechanism is connected to the winding mechanism via a limited fastening bolt, and the socket mechanism is located between the sleeve and the manual mechanism. While this winch can be used both electrically and manually, it has a complex structure, is difficult to maintain, and is difficult to replace parts.

[0004] Therefore, the key to solving the above technical problems is to develop an electric and manual integrated traction winch that is simple to operate, practical and reliable. Summary of the Invention
