Elevator device

Abstract

The invention discloses an elevator device. At least one damping device is arranged on a sill. The damping device is released when a door device is opened, and the damping device reaches a working position under the effect of self driving force and produces friction force which restrains up-down vibration of a car. When the door device is closed, the door device drives the damping device to reacha storage position. When the car is in a flat-layer position opened state, the car will not produce obvious up-down vibration when passengers enter and exit from the car, stability is higher, and rising comfort of the elevator is improved. The damping device has the advantages of being simple in structure, low in cost, small in size, high in reliability, high in universality and the like. Configuration is quite flexible, produced friction force is stable and continuous, installation and overhaul can be directly achieved in the car or the layer standing side, and hooking and collision risks will not be produced to components inside a shaft during operation of the elevator.

Description

technical field [0001] The invention relates to elevator technology, in particular to an elevator device. Background technique [0002] In the elevator system, the car and the counterweight are arranged in the lifting passage, guided by the car guide rail and the counterweight guide rail respectively, suspended by the traction rope wound on the driving host, and driven by the driving force of the driving host in the lifting passage. Move vertically in opposite directions to each other. [0003] The use of roller guide shoes can improve the ride comfort of running elevators. In recent years, in order to improve the comfort of elevator rides, more and more elevators use roller guide shoes. However, for an elevator equipped with roller guide shoes, the car is in the state of opening the door on the level floor, and when passengers enter and exit, the car will vibrate up and down. The main reason for this is that the load applied to the car caused by passengers entering and l...

AI Technical Summary

Problems solved by technology

[0008] The main problem is that it is necessary to install additional friction damping devices in addition to the roller guide shoes, including electromagnetic actuators and control devices for driving friction parts. The structure is very complicated and the cost is obviously increased; The common practice is to install the friction damping device vertically with the roller guide shoe. It is necessary to review the installation and operation space for the friction damping device on the elevator structure, and it will also increase the requirements for the height of the top floor of the elevator hoistway; in addition , since the friction damping device and the roller guide shoe are not an integrated structure, they need to be installed separately, which involves positioning and adjustment, etc., making installation and debugging more difficult

[0015] 4. The structure of the cam mechanism is difficult to adjust, because it is pushed in place when the car door is opened, and the cam mechanism produces resistance to the opening of the car door

If the design or installation position of the cam mechanism is inaccurate, it may affect the proper opening of the door and cause greater resistance to the opening of the door device

More seriously, it may cause damage to the door motor or even the entire door device

[0016] 5. The structure of the cam mechanism is difficult to adjust, and the adaptability is relatively poor, so it cannot easily deal with different sill gaps, that is, projects with different distances between the car door sill and the landing door sill

[0017] 6. When the car door is closed, the cam mechanism is reset by means of springs, etc. If the spring is aging or fails, the cam mechanism may not be reset in place, so that there is a risk of collision between the car and the inner parts of the hoistway when the car is running

[0018] 7. After the cam mechanism is reset, that is, when it is in the storage position, its main part is still outside the range of the car when viewed from the direction of the car's lifting and running, and may cause hooks on the inner parts of the hoistway when the car is running. risk

[0019] 8. The cam mechanism is set at both ends of the door opening direction of the door device, so only one or two in pairs can be set, and the expandability is poor

[0020] 9. The structure of the cam mechanism is still relatively complicated, not simple enough, and the cost is high
