Abstract
The utility model discloses a permanent magnet buffer which is arranged at the bottom of an elevator car and in a bottom pit of a hoistway and comprises at least one first permanent magnet and at least one second permanent magnet, wherein the first permanent magnet is arranged at the bottom of the elevator car, the second permanent magnet is arranged in the bottom pit of the hoistway, and the first permanent magnet and the second permanent magnet are arranged in a manner that homopolar magnets are opposite to each other. On the basis of the principle that homopolar magnets repel, when the elevator car falls off to approach the bottom pit of the hoistway, the magnetic force generated between the first permanent magnet and the second permanent magnet decelerate the falling elevator car so as to achieve the buffering effect.
Description
Technical field
The relevant a kind of permanent magnet energy disperser of the utility model is meant a kind of permanent magnet energy disperser that is used for lift car bottom and well pit especially.
Background technology
When elevator fell owing to fault, because elevator almost is the movement of falling object, used during elevator falling can produce very big impulsive force to the end, hoistway hole, easily the people in the elevator is caused life danger.
The utility model content
In view of this, main purpose of the present utility model is to provide a kind of permanent magnet energy disperser that can play buffering effect when lift car falls.
For achieving the above object, the utility model provides a kind of permanent magnet energy disperser, it is installed in the bottom and well pit of lift car, described permanent magnet energy disperser includes at least one first permanent magnet and at least one second permanent magnet, this first permanent magnet is installed on the bottom of lift car, described second permanent magnet is installed in the well pit, and described first permanent magnet and described second permanent magnet are like pole and are oppositely arranged.
Preferably, the N utmost point of described first permanent magnet is fixedly installed in the bottom of described lift car, and the N utmost point of described second permanent magnet is fixedly installed in the described well pit.
Preferably, the S utmost point of described first permanent magnet is fixedly installed in the bottom of described lift car, and the S utmost point of described second permanent magnet is fixedly installed in the described well pit.
Preferably, described first permanent magnet and described second permanent magnet are in twos over against setting.
Utilize the principle that the same sex is repelled each other between magnet, when lift car fell near well pit, the magnetic force that produces between first permanent magnet and second permanent magnet promotes car slowed down the car that falls, thereby reaches the effect of buffering.
Description of drawings
Fig. 1 is the embodiment scheme drawing of a kind of permanent magnet energy disperser of the utility model.
The specific embodiment
For ease of structure of the present utility model and the effect that reaches are had further understanding, the preferred embodiment that develops simultaneously of existing conjunction with figs. is described in detail as follows.
As shown in Figure 1, permanent magnet energy disperser of the present utility model is installed in the bottom and well pit 2 of lift car 1, this permanent magnet energy disperser includes at least one first permanent magnet 30 and corresponding at least one second permanent magnet 31 that is provided with, this first permanent magnet 30 is installed on the bottom of lift car 1, second permanent magnet 31 is installed on well pit 2, and first permanent magnet 30 and second permanent magnet 31 are like pole and are oppositely arranged, promptly the N utmost point of first permanent magnet 30 is fixedly installed in lift car 1 bottom, the N utmost point of second permanent magnet 31 is fixedly installed in the well pit 2, perhaps the S utmost point of first permanent magnet 30 is fixedly installed in lift car 1 bottom, and the S utmost point of second permanent magnet 31 is fixedly installed in the well pit 2.First permanent magnet 30 and second permanent magnet 31 in the utility model can be in twos over against settings.
Utilize the principle that the same sex is repelled each other between magnet, when lift car fell near well pit, the magnetic force that produces between first permanent magnet 30 and second permanent magnet 31 promoted lift car 1, and the lift car 1 that falls is slowed down, thereby reached the effect of buffering.
The above is preferred embodiment of the present utility model only, is not to be used to limit protection domain of the present utility model.
