- the thermal energy generated by the friction and the elastic potential energy of the spring 3-2 thereby achieving the buffer protection of the brake wire rope 4.
- the braking distance of the brake wire rope 4 is increased by the pulley block 2 to four times the maximum falling distance of the support plate 1, by increasing the brake wire rope 4 system.
- the moving distance can effectively extend the service life of the wire rope 4.
- the sum of the forces of the springs 3-2 of the fall arrester 7 is the gravity of the elevator.
- the process is as follows: When the elevator brakes, the speed of the elevator gradually decreases, the spring 3-2 contracts, the elevator The kinetic energy is gradually converted into the thermal energy of the hydraulic oil 3-8 and the potential energy of the spring 3-2. During this process, the pressure of the spring 3-2 is gradually increased, and when the force received by the spring 3-2 is balanced with the gravity of the elevator. The kinetic energy of the elevator is completely converted into the thermal energy of the hydraulic oil 3-8 and the potential energy of the spring 3-2, and the elevator stops moving. At this time, although the spring 3-2 also stores energy, due to the balance action of the elevator and the damping action of the hydraulic oil 3-8, the movement is not resumed, thereby avoiding a huge reverse impact on the elevator.
