Lifting attachments for loader

Abstract

The invention relates to a hoisting accessory and provides a hoisting accessory of a loader to solve the problem that an existing hoisting accessory cannot automatically perform unloading. The hoisting accessory of the loader comprises a connecting base, wherein at least one hoisting arm is arranged on the connecting base and adopts a box type structure, a hoisting hook with an opening facing downwards is fixedly arranged at the front end of the at least one hoisting arm, a hydraulic cylinder is arranged in an inner cavity of the at least one hoisting arm, a pin hole is formed in the end surface of the front end of the at least one hoisting arm, the end part of a piston rod of the hydraulic cylinder is connected with a hinge pin, the front end of the hinge pin is located in the pin hole and driven by the piston rod of the hydraulic oil cylinder to stretch and retract in the pin hole, and the hinge pin and the hoisting hook form a closed hoisting ring when the hinge pin stretches out. When the hoisting accessory is used for hoisting operation, the piston rod of the hydraulic cylinder in the at least one hoisting arm retracts, the piston rod of the hydraulic cylinder stretches out again after a hoisting rope is put in the hoisting hook, the hinge pin closes the opening of the hoisting hook to form the hoisting ring, the hoisting rope is located in the hoisting ring, safe hoisting can be realized, the piston rod of the hydraulic oil cylinder retracts after goods are hoisted in place, the opening of the hoisting hook is opened, the hoisting rope is separated from the hoisting hook, and unloading is realized.

Description

technical field [0001] The invention relates to an attachment, more specifically, to a hoisting attachment for a loader. Background technique [0002] At present, there are various types of attachments in the loader industry. The common ones include buckets, forks, snow shovels, and booms. As one of the important attachments, the boom occupies a certain share in the market and is widely used in Various lifting occasions. [0003] At present, the hoisting attachment of the loader includes a connecting seat, which is used to connect with the boom and the rotating link of the loader, and the connecting seat is provided with a boom, and the end of the boom is provided with a hook. The boom of this structure cannot be unloaded automatically during the lifting process, and manual unloading is required. This will increase the labor cost for the user, and the work efficiency is low, and there is a serious safety hazard in the process of manual unloading. Contents of the inventio...
