Abstract
The utility model relates to an elevator technical field specifically is a spring damper for elevator. The device comprises an upper end of the shock absorber and a lower end of the shock absorber, wherein one end of the upper end of the shock absorber is fixed on an upper beam of the elevator through a first fixing nut, the other end of the first fixing nut is fixed with a shock absorbing spring in a limiting mode through a first limiting screw, one end of the lower end of the shock absorber is fixed on a rope returning device through a second fixing nut, and the other end of the lower end of the shock absorber is fixed in the shock absorbing spring in a limiting mode through a second limiting screw. The utility model discloses an adopt the elastic coefficient to be 10-25kg/MM, the damping spring of elevator shock absorber is done to the spring that compression stroke is 20-40MM for it suppresses vibration frequency wideer (all effective to the vibration that is greater than 4 Hz), not only suppresses the amplitude great (less than or equal to 2.5MM), and temperature is little to the spring shock absorber influence moreover, service life is long, the spring compression stroke is bigger, thereby makes to take the elevator more comfortable.
Description
Technical Field
The utility model relates to an elevator technical field specifically is a spring damper for elevator.
Background
The existing rubber for the elevator car has the following defects that the damping compression stroke is 4-6 mm: 1. the range of the vibration suppression frequency is small (the vibration suppression effect on 4-30Hz is not good), 2, the suppression amplitude is small (less than or equal to 0.5mm), 3 and air temperature have large influence on the vibration reduction effect of the rubber, and 4, the service life is short.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a spring damper for elevator to solve the problem that proposes among the above-mentioned background art.
In order to solve the technical problem, the utility model discloses a scheme does:
the spring damper for the elevator comprises an upper end of the damper and a lower end of the damper, wherein one end of the upper end of the damper is fixed on an upper beam of the elevator through a first fixing nut, the other end of the first fixing nut is fixed with a damping spring in a limiting mode through a first limiting screw, one end of the lower end of the damper is fixed on a rope returning device through a second fixing nut, and the other end of the lower end of the damper is fixed in the damping spring in a limiting mode through a second limiting screw.
The elastic coefficient of the damping spring is 10-25 kg/mm.
The compression stroke of the damping spring is 20-40 mm.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses an adopt the elastic coefficient to be 10-25kg/MM, the damping spring of elevator shock absorber is done to the spring that compression stroke is 20-40MM for it suppresses vibration frequency wideer (all effective to the vibration that is greater than 4 Hz), not only suppresses the amplitude great (less than or equal to 2.5MM), and temperature is little to the spring shock absorber influence moreover, service life is long, the spring compression stroke is bigger, thereby makes to take the elevator more comfortable.
