a lifting device

Abstract

The invention relates to a hoisting device which comprises a first frame, a hoisting assembly and a second frame. The first frame is located on the upper portion of the second frame. The hoisting assembly is movably installed on the first frame and the second frame. The second frame is provided with an installation frame. The hoisting assembly comprises a connection rod movably connected to the first frame. The connection rod is provided with a sliding block. The end, away from the first frame, of the connection rod is movably connected with a hoisting hook. The hoisting hook is movably connected to the second frame. The hoisting assembly further comprises a sliding base fixedly installed on the installation frame of the second frame. The sliding base is provided with a sliding groove. The sliding block on the connection rod is movably installed in the sliding groove. The hoisting assembly further comprises a movable arm movably connected to the installation frame. The movable arm is tensioned to drive the second frame to move, and the sliding block is driven to move. The connection rod slides along the sliding groove, and the hoisting hook is tensioned to be disengaged from a hoisted object.

Description

technical field [0001] The invention relates to a hoisting device, in particular to a semi-automatic hoisting device suitable for hoisting shelves. Background technique [0002] In the fields of construction, transportation, etc., or in the daily operation of factories, it often involves the handling of large goods and shelves. In the prior art, it is usually necessary to perform a hooking operation on the goods, or use an auxiliary tool to assist in completing the hooking of the goods. But, in the prior art, it is convenient for man-made operation, and the hook material adopts asbestos rope etc. more, and it is easy to wear and tear, causes the safety accident of handling scene easily. [0003] At present, a variety of hoisting devices or equipment are also disclosed on the market. For example, CN101723242A proposes a semi-automatic hook, which uses a cylinder to cooperate with the hook assembly to complete the lifting of the object, but the equipment is complicated and de...
