The application range of group hoist electric hoist is relatively wide. We also call it dhp electric chain hoist. It is a kind of electric chain hoist. It is also called slow electric chain hoist. To be able to use one, it must be used in conjunction to better play his role. This article mainly introduces the structure and the detection of the motor in detail, and understands these to better use the product. The main components of the group hoist electric hoist group hoist are hook, body, chain and hook. In order to give you a more intuitive understanding of this group of upgrades, the details will be introduced below: 1. Hooks include: hooks, card boards, hook racks, cross pins, cruise ships, etc. Second, the main components include: 1, the main case also includes housing, nuts and washers. 2. The hoist head includes: gears, three plates, lifting wheels, baffles (chain shunts), and support rods. 3. Planetary reducer includes box, planet frame, planet gear, flat key, spring retainer. 4. Engine. Including motor, sun gear, flat key, fixed ring. Third, the chain: 80-level large Baotou alloy steel chain. 4. Lower hook parts: hook, cable, cruise, lower shelf.The group hoist electric hoist lift electric hoist mainly drives the planetary gear through the motor, the planetary gear drives the 5-foot-long shaft through the planetary frame, the 5-foot-long shaft drives the blade gear, 4-tooth short shaft and spline hole gear. In this way, the device on the sprocket hole gear lifting sprocket will drive the lifting chain, thereby stably lifting the weight. The group-mounted electric hoist is braked by the disc motor under load. The group hoist electric hoist motor is one of the important components in all electric hoists. The group hoist that solves this problem is a first-class motor that uses three-phase disc braking. It is precisely because of this motor that the group hoist electric hoist can Achieve the same lifting operation. The group hoist is a commonly used synchronous chain hoist. In the daily construction I application field, the motor is an indispensable part of the group hoist.1. In the operation group hoist of each floor, we should stop the machine 2-3 times to check each group of hoists. 2. Continuously monitor the chain of each group of elevators. If individual chains are slightly tight, they should be adjusted immediately. Prevent chain cracking. 3. Technicians should always pay attention to the sound of group hoist electric hoist. If there is a different reaction, stop working immediately and find out the cause before normal operation. 4. If the group hoist is damaged, the accessories should be replaced immediately, or the electric hoist should be replaced directly to avoid the above problems. 5. If you need the same landing operation, you should try to choose the same type, motor and speed of the same group of suspended electric hoists.
