Load self-adaptive pneumatic balance hoisting device

Abstract

The invention relates to a load self-adaptive pneumatic balance hoisting device. The device comprises a lower base, an upper base which is connected with the lower base through a first in-built bearing, a four-bar linkage which is hinged to the top of the upper base, a pneumatic control system which is in transmission connection with the four-bar linkage, and a hoisting fixing unit and a heavy object block which are respectively arranged at the front end and the rear end of the four-bar linkage; the pneumatic control system comprises a pneumatic control box which is fixedly connected with the upper base and a pneumatic cylinder which is connected with the pneumatic control box; the top of a pneumatic rod of the pneumatic cylinder is hinged to the four-bar linkage. Compared with the prior art, the existing constant load hoisting is improved into variable load self-adaptive hoisting by the load self-adaptive pneumatic balance hoisting device; the technical advantage that the existing hoisting structure is simple and quick are reserved; the defects that the existing hoisting structure can only perform constant load hoisting, is low in efficiency and the like can be overcome; the overall structure is simple and compact; load self-adaptive automatic control can be realized.

Description

Technical field [0001] The invention belongs to the technical field of pneumatic machinery, and relates to a load-adaptive pneumatic balance lifting device. Background technique [0002] As a new type of mechanized lifting tool used in the workshop, the balance crane is widely used in the production and processing of small and medium batches of multiple varieties. The mechanization of the handling of medium-weight objects in small batches and multiple varieties is a long-standing difficulty that has been difficult to solve. Usually, cranes and electric hoists were often used in the past, but it was difficult to ensure mechanized production on the assembly line. The traditional handling efficiency is low, the precision is low, and the direction is also limited, so in many cases this cannot meet the production needs. The emergence of the balance crane has solved these difficult problems. [0003] Balance crane is a new type of material lifting equipment, which uses a unique spiral...

Problems solved by technology

In comparison, the biggest feature of the balance crane device of the present invention is that it can adapt to the load, which overcomes the deficiency that the traditional balance crane can only lift with a fixed load, and the operation is stable without shaking after lifting objects like an electric hoist. Objects can be moved in three-dimensional space by holding them by hand. They are safe and equipped with overload protection equipment. However, the existing electric hoists use steel cables for hoisting, which has certain potential safety hazards.
