Description
Technical Field
The invention relates to the technical field of elevators, in particular to an elevator.
Background
The elevator mainly transports passengers, can also transport household articles or articles for daily use, and is very important to select a proper elevator before the elevator is installed, and meanwhile, an elevator steel wire rope is an important safety device of the elevator, so that the elevator car can be safely lifted and dropped, and the safety guarantee function without alternatives is played. Because the reasons for the wire breakage and the kinking of the elevator steel wire rope are complex and diversified, the problems are caused by various factors, the inspection, the maintenance and the maintenance of the elevator steel wire rope are enhanced, and the installation supervision inspection and the periodic inspection are strictly carried out according to the regulations of the State quality supervision Bureau, so that the safe and efficient operation of the elevator is ensured.
When the elevator is in a static state, no current passes through a coil of an electromagnetic elevator brake of the traction motor, and the brake wheel is tightly held under the action of the pressure of the brake spring due to the fact that attraction force does not exist among electromagnetic iron cores and the brake shoe is used for ensuring that the motor does not rotate; when the traction motor is electrified and rotated, the coil in the brake electromagnet is electrified and simultaneously, the electromagnetic iron core is quickly magnetized and attracted to drive the brake arm to enable the brake spring to bear acting force, the brake shoe is opened and completely separated from the brake wheel, and the elevator can run; when the elevator car reaches a required stop, the traction motor loses power, the coil in the brake electromagnet loses power at the same time, the magnetic force in the electromagnetic iron core disappears rapidly, the iron core is reset through the brake arm under the action of the brake spring, the brake wheel is embraced by the brake shoe again, and the elevator stops working. The bidirectional thrust elevator brake is a friction type brake which generates bidirectional electromagnetic thrust when being electrified to separate a brake mechanism from a motor rotating part, eliminates electromagnetic force when being powered off and forms power-off brake under the action of external brake spring pressure.
If the elevator breaks down suddenly, the elevator can lose control and rapidly drop, the elevator suddenly drops under the general condition because the steel wire rope for pulling the elevator breaks, the whole back and the head are tightly attached to an inner wall which does not lean on a door to form a straight line, a wall body is used for protecting the spine, the knees are in a bending posture, the stress pressure is borne by bending the knees, the heels are lifted, the tiptoe standing posture is formed, the ligament is the unique tissue which is rich in elasticity of the human body, the stress pressure is borne by bending the knees and tiptoe standing posture, the buffer is increased, the stress is borne by the bone more than the bone, and the impact force caused by the elevator dropping is reduced. The conventional emergency braking device for the elevator cannot be forcibly stopped once a steel wire rope is broken, and a wall is seen behind an opening door of an elevator door at a position where the emergency braking device possibly stops, so that the rescue difficulty is increased, and the elevator cage is violently collided with the ground due to the rapid falling, so that the elevator cage is seriously damaged and people in the elevator cage are injured.
