Separation and reunion type winding drum and winch

Abstract

The invention relates to the technical field of hoisting equipment, in particular to a separation and reunion type winding drum and a winch. The separation and reunion type winding drum comprises a drum body and a winding drum shaft coaxially arranged with the drum body, wherein a separation and reunion device comprising mounting assemblies and separation and reunion assemblies is arranged on thewinding drum shaft and is used for controlling communication and separation of the drum body and the winding drum shaft. According to the separation and reunion type winding drum, the plurality of mounting parts and the separation and reunion assemblies are arranged between the winding drum shaft and the drum body, so that a plurality of contact frictional parts are arranged between the winding drum shaft and the drum body to increase the frictional contact area and avoid the slip phenomenon. On the condition that the separation and reunion assemblies fit the drum body, it is ensured that thewinding drum shaft can drive the drum body to rotate stably and reliably. The separation and reunion assemblies can be partially or completely used to ensure the contact frictional force of the separation and reunion assemblies and the drum body, so that the winding drum shaft drives the drum body to rotate stably and reliably, and lifting and falling of a heavier object are achieved. The winch comprises the separation and reunion type winding drum.

Description

technical field [0001] The invention relates to the technical field of hoisting equipment, in particular to a clutch type reel and winch. Background technique [0002] There are many types of winches, and some winches need to switch between the separated state and the connected state between the drum body and the drum driving mechanism when in use. In the separated state, the mass and moment of inertia of the cylinder body of the reel are small, which can realize rapid rotation, so that the objects connected with the steel wire rope on the reel can fall quickly. In the connected state, the reel driving mechanism can drive the cylinder body of the reel to rotate, and control the lifting of the object connected with the steel wire rope on the reel. [0003] For example, when the hammer winch is installed on the engineering ship, when the hammer falls freely from a certain height, in order to avoid the damage to the motor equipment caused by the passive high-speed rotation of ...
