Problems solved by technology

During the use of the hand chain hoist, if the object being lifted is overweight, it will cause destructive damage to the hand chain hoist. In severe cases, the lifting chain will break due to the limit of the lifting chain, which will pose a great threat to the safety of the workers. Therefore, the hand chain hoist is required. Chain hoists add load limiting function

Abstract

The invention discloses an aluminum alloy chain block with a load limiting function. The aluminum alloy chain block with the load limiting function comprises a shell, a first fixing plate and a secondfixing plate are arranged in the shell, a long gear shaft is arranged in center holes of the first fixing plate and the second fixing plate in a penetrating mode, a first gear is arranged at one endof the long gear shaft, a spline is arranged at the other end of the long gear shaft, the first gear is connected with a sheet gear set located on a first housing, the spline is connected with a brakeassembly, the long gear shaft is further provided with a hoisting chain wheel located between the first gear and the brake assembly, one end of the hoisting chain wheel is provided with a second gearconnected with the sheet gear set, a first convex groove and a second convex groove which correspond to the first fixing plate and the second fixing plate respectively are formed in the hoisting chain wheel, a hoisting chain located between the first convex groove and the second convex groove is arranged on the hoisting chain wheel in a winding mode, and a lower lifting hook is arranged at the tail end of the hoisting chain. By the adoption of the structure, the aluminum alloy chain block with the load limiting function is high in safety, compact in structure, small in size and convenient tocarry.

Description

technical field [0001] The invention relates to the technical field of chain hoists, in particular to an aluminum alloy chain hoist with a load limiting function. Background technique [0002] Chain hoist, also known as fairy hoist, chain hoist, chain hoist, chain hoist, manual hoist, is a kind of manual lifting machine that is easy to use and easy to carry, also known as "chain hoist" or "chain hoist". During the use of the hand chain hoist, if the object being lifted is overweight, it will cause destructive damage to the hand chain hoist. In severe cases, the lifting chain will break due to the limit of the lifting chain, which will pose a great threat to the safety of the workers. Therefore, the hand chain hoist is required. The chain hoist adds a load limiting function. Contents of the invention [0003] The object of the present invention is to provide an aluminum alloy chain hoist with load limiting function, which has high safety, compact structure, small volume an...
