Electric unmanned unhooking lifting appliance

Abstract

The invention discloses an electric unmanned unhooking lifting appliance which comprises a lifting arm and a lifting hook integrated with the lifting arm. A push rod support is fixedly arranged on thelifting arm, a small driving motor is fixedly arranged on the push rod support, a gear is mounted on an output shaft of the driving motor, and a rack meshed with the gear is movably arranged on the push rod support. The outer wall of an inverted-T-shaped push rod is sleeved with a return spring, and the electric unmanned unhooking lifting appliance further comprises a steel wire rope which sequentially penetrates through a first transverse hole passage and a second transverse hole passage. After it is ensured that a lifting rope or a lifting ring is hung in the lifting hook, the lifting ropeor the lifting ring can be locked in the lifting hook, so that operation accidents or casualties caused by accidental unhooking are avoided, meanwhile, a lifting belt can be automatically discharged from the lifting hook after lifting operation is finished, the lifting hook is separated from the lifting rope or the lifting ring, and the purpose of unmanned unhooking is achieved.

Description

technical field [0001] The invention relates to the technical field of hoisting tools, in particular to an electric unmanned decoupling hoist. Background technique [0002] During the hoisting operation of the existing slings, the heavy objects to be hoisted must be manually hung on the hooks of the slings through the slings or rings. Take it off the hook, especially the bulk material bulk ton bag, which requires frequent lifting operations during loading, unloading, and stacking, and the slings of the ton bag are made of soft fiber materials , When decoupling, it cannot be decoupled by itself, and the operator must climb up or down to remove the ton bag sling from the hook. This method is inefficient and unsafe, and it also increases labor costs. Contents of the invention [0003] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide an electric unmanned unhooking sling, which can lock the sling or ring in the hook afte...
