Hydraulic winch

Abstract

The invention discloses a hydraulic winch which comprises a winding drum assembly, a power mechanism and a piston sleeve assembly, and a separated transmission part is connected into the winding drum assembly; the power mechanism is in transmission connection with the separated transmission part, and a piston rod of the piston sleeve assembly is rotationally connected with the separated transmission part; and the other end of the piston rod extends out of the piston sleeve assembly and forms an axial limiting mechanism, the piston sleeve assembly is further provided with a movable clamping mechanism, and the movable clamping mechanism can be clamped with the axial limiting mechanism so that the separated transmission part and the winding drum assembly can keep transmission connection or transmission separation. The piston rod is used for driving the separated transmission part to achieve transmission connection or transmission separation with the winding drum assembly, so that free switching of a hydraulic transmission mode or a free rotation mode of the winding drum assembly is achieved, the use requirements of different working conditions are met through two different working modes, the working modes are diversified, the applicability is wider, and the piston rod is clamped through the movable clamping mechanism, so that the stability of a transmission working mode is ensured.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing auxiliary equipment, in particular to a hydraulic winch. Background technique [0002] The hydraulic winch is a light and small transmission device that winds a wire rope or chain with a reel to lift or pull objects. It is widely used in the lifting or flat dragging of materials in automobiles, transportation, marine engineering, construction, water conservancy engineering, forestry, and mines. [0003] When the hydraulic winch is in use, such as in the manufacture of auto parts, some special working conditions need to realize free fall and rapid release, manual free rope release, etc., which requires the hydraulic winch to be able to realize hydraulic transmission and free rotation. The working mode of multiple working conditions, And the working mode can be switched at will according to the needs, so there is a demand for a variety of working modes and operating modes of hydraul...

Problems solved by technology

[0003] When the hydraulic winch is in use, such as in the manufacture of auto parts, some special working conditions need to realize free fall and rapid release, manual free rope release, etc., which requires the hydraulic winch to be able to realize hydraulic transmission and free rotation. The working mode of multiple working conditions, And the working mode can be switched at will according to the needs, so there is a demand for a variety of working modes and operating modes of the hydraulic winch in the industry, but the existing hydraulic winch has few products that can meet the demand, and cannot meet the needs of some special working conditions
