Abstract
The invention provides an elevator falling damping buffer device and an installation method thereof. Through a damping piston rod, a return spring, a damping oil cylinder, damping oil discharge holes, an oil return cavity, an oil return box and other devices, a falling lift car can start to decelerate and descend slowly after making contact with the damping piston rod by 10 cm. The working principles of the elevator falling damping buffer device comprise that a rubber blanket 1 arranged at the bottom of the elevator lift car makes contact with the damping piston rod 2, the damping piston rod 2 starts to do follow-up descending movement, and after the damping piston rod 2 descends by 10 cm, damping oil in the damping oil cylinder 9 is discharged through the damping oil discharge holes 10; every time when the damping piston rod 2 descends by 10 cm, the damping oil in the damping oil cylinder 9 is discharged through the damping oil discharge holes 10 and enters the oil return box 5 through the oil return cavity 8; gas is exhausted through an oil cylinder exhaust hole 15 in the oil return box 5, thus, the lift car descends slowly, and the safety of people in the lift car is ensured; after the lift car is lifted, the return spring 3 drives the damping piston rod 2 to go up, the gas enters the oil return box 5 through a reset exhaust hole 11, and the damping oil enters the damping oil cylinder 9 through the damping oil discharge holes 10; and accordingly, the lift car is stopped in an effective stroke, and the people in the lift car are protected.
