First of all, we must understand the principle of reading the elevator: the rotary encoder can function as the rated speed memory station distance, and with the brake brake, the position of the flat magnetic isolation board is the main target of flat parking, if the level is separated The magnetic plate device is moved, the elevator will also stay on the layer, and the magnetic plate is searched up and down to refill the encoder level data. If not found, the elevator will open the door up or down and then stop. The probability of reading a landing error is almost zero, and the probability of an accident in reading a landing error is also zero.

Safety Components include: brake, speed limiter, broken rope wheel, upstream overspeed protection device, anti-fall Safety Gear, lower speed, lower limit, lower limit, buffer.

Among them, the brake is most likely to fail. The brake: the most frequently used one in the brake system, the highest friction temperature can reach 150 degrees Celsius. If the temperature of the brake is too high, it will cause serious damage. If it is used again after cooling, there will be a situation where the brake is too large, and the gap of the brake must be adjusted by the manufacturer. The maintenance personnel would rather stop. Will adjust by yourself. When the brake fails, the elevator falling speed exceeds the rated speed, and the huge centrifugal force will open the movable arm of the speed limiter to the cone. The action is: inertia pulls the broken rope wheel - the speed limiter wire stops moving. - Pull up the Progressive Safety Gear - the card stops moving on the elevator track. The safety gear must not be a problem, but the speed limiter has more problems. As long as there is a little foreign matter stuck on the movable arm of the speed limiter, it is a problem that the centrifugal force of the falling can not open the movable arm. The speed limiter can't be opened, and the safety gear can't work. Even if the speed limiter works, the safety gear will work. If the speed is fast enough, the power of the safety gear will be the same as the power falling on the ground. If it doesn't work, the elevator will always fall to the bottom, the stroke will hit the upper and lower speed, slow down: you can limit the elevator speed to 40 cm per second, which is the speed when you reach the top and bottom when you take the elevator. Very slow reason. If this device works, you should be thankful that this is the gentlest safety switch. If there is no deceleration, it will only hit the lower limit device in less than 0.1 seconds. The lower limit position: the maximum stroke of the elevator. Unless this safety circuit is shorted, no matter how priority maintenance or normal operation will not exceed this device. . If it doesn't work, the speed calculation of the following crash will hit the lower limit switch within 0.001 seconds. This switch will only be disabled when the seal star relay fails or shorts the safety loop. Otherwise, only the motherboard is completely broken. , the drive inverter is also bad enough to be ineffective. If this fails, don't expect the buffer, it must be that life is not doing extremely evil! If the landing is high enough, the bones will be broken.

This is caused by the thunder of the landlord. . The boss re-purchased a set, which caused the landlord to pull the gourd for three days. He stood still and couldn’t move and sat, pulling more than two tons! 95 meters floor! The days were hot, the sweat was raining, and the butt was worn out. .

This is a broken wire. The theoretical load is eight tons. It only breaks when it takes less than two tons. The small Japanese thing is worrying!

The only complete one is this reverse rope.

The lower half of the vertical beam becomes a transformer,

Five major mistakes:
1. Keep calm. Under normal circumstances, the elevator trough has anti-fall safety device, and the safety device will not malfunction.

There are no safety devices that won't fail, otherwise there will be no accidents!

2, use the alarm or walkie-talkie, mobile phone for help, such as no alarm or walkie-talkie, when the phone fails, you can scream at the door, you can take off your shoes and beat.

Mobile phones generally do not malfunction, the common Mitsubishi, calendar, Sims, Sini, West Ji, Fujitec, Juli, Giant KONE, Juli, fast will not use pure stainless steel car wall, at most only thin Mirror stainless steel, as long as the stainless steel does not exceed 0.3 mm, has little effect on the signal, except for PHS, and there is a signal box of China Mobile in the hoistway. Some also have Unicom, but I only know that each hoistway is mobile.

3. If there are no trained rescuers outside, do not climb out of the elevator.

If there are rescuers, you don't have to climb out of the elevator. Even if you wait for the rescuers, you have to wait for at least half an hour. Remember to be kind to the rescuers. Otherwise, just find an excuse to let you play for a long time.

4. Never try to force open the inner door of the elevator. If there is an emergency exit on the ceiling of the elevator, don't climb out. If the exit plate is accidentally closed, the elevator may suddenly become unbalanced. In the dark elevator trough, it may be tripped by the Elevator Cable or slipped due to the grease, and fall off the top of the elevator.

The safety window of the elevator is generally not open, because I have seen all the elevators with safety windows are tightened, and there will be abnormal noise when the operation is not tightened. That is, it can be opened, the height is two meters and forty centimeters. Even if there is a ladder, the person who is very slim can bend over and get covered with oil and laboriously climb out. After going out, pay attention, can not close the safety window, do not hold it. Soft facilities such as steel wire are available behind the door opening method.

5. If the elevator crashes, be sure to take the following methods to save yourself: no matter how many floors, press the buttons on each floor. When the emergency power is turned on, the elevator can stop falling immediately; if there are handrails in the elevator, please Keep your hands close to the armrests to prevent the center of gravity from falling; the knees are in a bent position, and the knees are bent to withstand the pressure of the heavy impact; when the heel is lifted, it is a lame, and if there are few people in the elevator, it is best to put the two arms out to hold the handrail. Or attached to the elevator wall; the entire back and head are close to the inner wall of the elevator, in a straight line, using the elevator wall as the protection of the spine.

The 95-meter-long 30-storey height that I experienced was dropped in only 4 seconds, and there was no time to choose the layer to do the buffering action. And the inner wall is on the opposite side, even if the person is still alive, waiting for more than two tons of the pair to fall down, everyone knows.

Generally speaking, the elevator is very safe and generally does not cause accidents. I have seen that the bumper car that has fallen more than one meter high is completely smashed into the concrete foundation. The accident is generally modified, down. The problem of adding layers is not that big, and it is most dangerous to add layers and change to a machine room. Almost all safety devices will not work. In the event of a power outage, in the elevator without emergency power supply, you can push the inner door of the elevator and gently push it open. After pushing it open, you will see the hall door, which is the outside. The door has two round wheels on the upper right side of the door, some of which are up and down, and some of which are left and right. Generally, the left or upper wheel is opened to the right by hand, and then quickly goes out, pay attention to the door to be completely opened, and Keep both doors open under the premise of opening the door. If you are between the two floors and the lower layer is higher than one meter, do not go out. Although there is a car foot protection version that can guarantee a certain safety distance, it is hard to say that if it is more than one meter away, it will fall into the hoistway.

There is no need to panic in the operation of the elevator, and the big trouble is useless. Before you buy a house, you must fully feel the elevator. If there is any abnormal noise in the operation, you will definitely have problems in the future. If you think, even the basic track can not be adjusted but can be put into use. How much is the technical quality supervision bureau? Can the red envelope pass?
