Description

Technical Field

[0001] This utility model relates to the field of elevator chain technology, and in particular to an elevator chain transmission assembly. Background Technology

[0002] A hoist is a large mechanical device that transports goods by changing their potential energy, such as a mine hoist or a dam hoist. Broadly speaking, elevators, overhead cranes, winches, trolleys, cranes, and gate hoists can all be called hoists. Hoists generally refer to large mechanical devices with high power and strong lifting capacity. The transportation process is completed by using a power machine to drive a flexible steel wire rope and the transported goods up and down. The steel wire rope is an indispensable and important component of lifting machinery, and the main types include phosphated coated steel wire rope, galvanized steel wire rope, stainless steel wire rope, and bright steel wire rope, etc. Chain-driven elevators utilize chain-driven buckets to scoop up materials and transport them to a high place for delivery. During long-term operation, especially under heavy loads and high speeds, the chain can experience wear and stretching, leading to a longer pitch. This can cause tooth skipping when the chain meshes with the sprocket. Therefore, we have proposed a chain drive assembly for elevators. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model discloses a chain drive assembly for an elevator. The assembly uses a chain to lift and drive the feeding component, placing the material to be lifted inside the feeding frame. The motor is then started to drive the drive shaft to rotate. The rotation of the drive shaft, through the cooperation of the sprocket and the chain body, drives the auxiliary shaft and fixed roller to rotate. The rotation of the fixed roller drives the track to rotate, which in turn drives the lifting bucket to lift the material. The lifted material is then discharged through the discharge chute. The elevator housing is inclined to facilitate material discharge. This utility model discloses a chain drive assembly for a hoist. Through a chain lifting tensioning and rust-prevention component, a spray head can spray lubricating oil onto the outer surface of the chain body. A polyurethane elastomer annular sleeve is provided on the outer side of the tension roller, ensuring even application of lubricating oil to the chain body surface without causing wear on the tension roller. Excess lubricating oil can be retained on the bottom inner wall of the protective cover. Controlling the circulation pump allows the lubricating oil to be recovered to the lubricating oil storage tank via a return pipe, preventing waste. During prolonged use, the chain body may experience wear and stretching, leading to an increased pitch. In this case, an electric telescopic rod can be controlled to move the mounting frame and tension roller, allowing for adjustable chain tension. Furthermore, during chain use, the cooperation of springs and sliding rods allows the tension roller to buffer, preventing tooth skipping during chain rotation.
