When we use the elevator elevator when we must pay special attention to it, once the fault after the impact is a big branch factory, especially the safety accident will cause a lot of trouble. So how can you ensure the safe operation of the elevator when it is used? Here are some tips:
Elevator elevator manufacturers with the use of elevator in life gradually increased, the safety of the elevator is also a frequent occurrence, in order to everyone’s work safety, lift manufacturers for everyone to popularize the cause of the accident.
The working principle of elevator brake
Simply lift the working principle is a principle of shaft, the transfer is commonly used shaft with, normally closed, single disc brakes, installed in the tail end of the motor, stretch out shaft, in order to make the cargo-lifts color loose brake clearance of the brake with the machine cutting a brush wear automatic adjustment, the automatic regulating device in cargo-lifts.
The reason why the elevator can’t stop
1. Due to the insufficient thickness of the top shoulder, this device will be worn out with the increase of the number of times used, so the elevator will have the problem of service life. If the thickness is insufficient, the joint cannot continue to move right due to the restraint of the automatic regulating mechanism, thus the brake friction plate cannot be pressed tight. In addition, if the disc and cone between falling into the dirt or debris, this will also make the top cover top is not tight, resulting in the ball can not implement effective braking.
2: the outer circular surface of the casing is not hard enough. After a period of time, the outer surface is pressed out of the groove by the ball. When the ball is advanced in the groove, the ball cannot be withdrawn, leading to the automatic adjustment mechanism that cannot be moved, so the armature is pressed tightly to brake friction plate.
3. There is also a special type of cargo elevator with four automatic regulating devices, which are jointly controlled and located at the four corners of the cargo elevator. If the thickness of the top sleeve lugs in the four automatic regulating mechanisms is too different, then they cannot move synchronously and cannot press the armature tightly, which makes the cargo elevator unable to brake.
The elevator, which is controlled by four automatic control devices, sounds very stable, but in fact, it can easily cause tilt and collapse, so you should be careful when operating.
Above is the elevator elevator only understand the introduction and some specific analysis of the fault, I hope you can have mobile harvest and help after reading.
