Electric chain hoist with anti-drop chain effect
Electric chain hoist is a kind of light and small lifting equipment, mainly used in factory warehouses, commercial warehouses, supermarkets, shopping malls, storage departments and other places. The electric chain hoist in the prior art mainly consists of a reducer, a motor and a chain. However, due to the unreasonable layout of the reducer, motor and chain, the electric chain hoist has a large volume. At the same time, the electric chain hoist has a large number of parts. Since most of its parts are non-standard parts, the production of these parts still needs Many customized molds are not conducive to the production management of parts and the risk control in the production process of electric chain hoists. In addition, the existing technology does not provide good protection for the chain around the sprocket. It is easy to get off the chain during the ascent process, resulting in low safety of the electric chain hoist.
The electric chain hoist chain device includes a common box and a motor assembly and a reducer assembly that are separately arranged on both sides of the common box. The two ends of the output shaft of the reducer assembly are respectively sleeved with support bearings, and the support bearings It is fixed on the supporting bearing seat inside the shared box; it is characterized in that it also includes a chain assembly, the chain assembly includes a sprocket, a chain and a chain guide device to prevent the chain from falling off, and the sprocket is arranged on the On the output shaft of the reducer assembly, and the sprocket is located between two supporting bearings; the chain guide device includes a chain guide ring and two chain guide plates, the two chain guide plates are respectively connected to the chain of the chain guide ring The inlet and the outlet are connected, the chain guide ring is arranged outside the sprocket, and the chain is located between the sprocket and the chain guide ring and is wound on the sprocket.
The chain device of the electric chain hoist adopts a reasonable layout of the reducer assembly, motor assembly and chain assembly, making the structure of the actual chain device more compact, and at the same time, it is supported by the two ends of the output shaft of the reducer assembly The bearing supports the lifting load, and the output gear is cantilevered at one end of the output shaft of the reducer assembly, which effectively improves the force of the output shaft and ensures the safety of the chain device.
