Speed variator can perceive rapidly car body and be in stall conditions, and send signal to microcontroller immediately, and microcontroller is logical
The operation of oil pump on four groups of minisize dc hydraulic push rods of control is crossed, and then minisize dc hydraulic push rod is driven to drive roller rotation,
Rubber shirt rim is rotated counterclockwise with roller to 90 °, opposite with gravity direction by generating four groups between rubber shirt rim and the electric borehole wall
Frictional force, to achieve the purpose that stall deceleration of elevator；The structure design of entire elevator hydraulic reduction gear is simple, not only
Manufacturing cost is relatively low and is easy to daily maintaining, and can effectively realize and slow down to stall elevator, to protect
Personnel and property in shield elevator are injury-free.
By the way that the shape of rubber shirt rim is designed as arc, the Design of length of rubber shirt rim is to assemble the length phase of mounting groove
Deng when elevator is in stall conditions, CONTACT WITH FRICTION occurs for rubber shirt rim and hoistway wall, the rubber shirt rim of arc not only intensity
It is good, and there is good decelerating effect.
By the way that in setting reinforcing rib and the second bolt, the other end of minisize dc hydraulic push rod is passed through reinforcing rib and rubber
Shirt rim connects, and then is connected with rubber shirt rim component, while the second link slot is inserted at the both ends of reinforcing rib and passes through the second spiral shell
Bolt is connected with rubber shirt rim, can be increased the rigidity of rubber shirt rim and be born to transmit the driving force of minisize dc hydraulic push rod.
When elevator when being contacted with ground, can be with by the Buffer Unit being made of upper buffer layer, bottom breaker and buffer
Good cushioning effect played to elevator, reduces the impact force between elevator and ground, protects personnel in elevator and property not
It incurs loss.
By by upper buffer layer and bottom breaker be both designed as by set gradually from top to bottom the first rubber layer, air bag layer
It is formed with the second rubber layer, the gentle cystoblast of rubber layer has good cushioning effect, improves the buffering effect of buffer layer.
When elevator and ground contact, Buffer Unit starts to play cushioning effect, and buffer starts to compress, when buffer not
When can contain that elevator stops, the beam on limited post and limited post starts to play the role of secondary buffer, further to limit
Elevator processed is run down until elevator stop motion.
By the way that the horizontal position design of bottom breaker in the lower section of the free end of rubber shirt rim, can be prevented rubber shirt rim
Component is contacted with ground and is damaged one step ahead, and the distance between free end of bottom breaker and rubber shirt rim should be buffering
The compression work sum of the distance of the compression work distance of device and limited post and beam.
By using polyurethane bumper absorber, polyurethane bumper absorber has good buffer effect, the good spy of impact resistance, compressive property
Point, and polyurethane bumper absorber is not only buffering course is noiseless, no-spark, explosion-proof are good but also safe and reliable.
Example the above is only the implementation of the present invention is not intended to limit the scope of the invention, every to utilize this hair
Equivalents made by bright specification and accompanying drawing content are applied directly or indirectly in relevant technical field, include similarly
In the scope of patent protection of the present invention.
