Home lift installation and operation

The main structure and purpose of the guide rail lift: The mechanical part of the guide rail lift mainly includes three parts: lift device, track device and belt change device. Among them, the lift device is mainly used to suspend the lifted person and is the core part of the whole organization. The track device The main function is to provide the movement trajectory to make the operation more smooth. The belt changing device is used to switch the track when the elevator is going through the door. The internal structure of the lifting device lifting device is mainly composed of a gear mechanism, a bracket, a worm gear, a guide mechanism, a boom, an upper shell, a lower shell, and the like. Gear Mechanism The gear mechanism mainly includes large and small gears, wrapped belt pulleys, a center shaft, and an insurance device composed of a stopper buckle and a torsion spring.
Selection of closed gear drive, large and small gears are selected steel, after quenching and tempering, are soft tooth surface, due to the common failure mode of the closed soft tooth surface gear transmission is tooth surface pitting, so the design according to the tooth surface contact fatigue Strength calculation, according to the root bending fatigue strength check. The bracket bracket is used to fix and support all the mechanical parts and some electrical components inside the lifting case body, and is mainly welded by the side plate, the connection pipe and the connection piece, and the materials are all selected, wherein the thickness of the two side plates is reduced at the same time to reduce The weight of the bracket is designed with many holes on both sides. The worm and worm gear has the advantages of large gear ratio, compact structure, small impact load, smooth transmission and low noise, etc., and has the characteristics of reverse self-locking. The worm gear reducer can be used to ensure that the transmission mechanism can be self-locked when the motor is powered off. The involute worm is used, and the material is steel. The spiral surface is quenched to increase the transmission efficiency and increase the wear resistance. The worm gear material is polyoxymethylene. The plastic worm gear has the advantages of good processing economy, smooth transmission, vibration absorption and noise reduction, light weight, wear resistance and self-lubrication, etc., which makes the design of the lifter more user-friendly.
The guide mechanism guide mechanism is mainly composed of guide plastic tubes, guide brackets, compression springs, safety plugs, guide housings, and guide shafts. As a guide mechanism, a semi-section is formed, and a narrow slit is formed between the two guide plastic tubes. The belt protrudes out of this narrow slit to prevent the tape from being twisted and play a guiding role. The safety plug is supported by the guide bracket and the compression spring. In order to prevent the compression spring from losing its stability after being forced, a small guide rod is designed on the safety plug, and the gap between the small guide rod and the spring is designed according to the table. The jib shaft is welded with two jib hooks at each end. The material is selected, and the quenching and tempering process is performed. Together with the hooks of the lower shell of the box body, three suspending points are formed, which are lifted by the lifter through the soft support spreader. The weight of the jib, in order to enable the lifter to be in a comfortable state during the ride, the distance between the hangers of the two jibs refers to the relevant data of the horizontal size as a design reference. The balance bar is used to maintain the balance of the lifting device. Designed as a hollow tube, it reduces the overall weight of the boom.
