Adaptive Elevator Buffer Damping Device

Abstract

The invention discloses an adaptive elevator buffering and damping device, which comprises a buffering plate arranged under the elevator car body and used for jointing with the bottom of the car to provide buffering force for the car when the car is falling, a magneto-rheological damping body and a control system The control system includes: an electromagnetic coil for providing an electromagnetic field for the magnetorheological damping body; a power supply unit electrically connected to the electromagnetic coil for providing power for the electromagnetic coil; a drop parameter detection unit for detecting the elevator car body the falling parameter; the central processing unit is used to receive the data signal of the falling parameter detection unit and send a power supply command to the power supply unit according to the signal. During the buffering process, the damping force can be adaptively adjusted to achieve a smooth downward buffering.

Description

technical field [0001] The invention relates to a special equipment safety system, in particular to an adaptive elevator buffer and damping device. Background technique [0002] The van elevator is a means of transportation for vertical transportation, which is closely related to people's daily life; the existing van elevator is mainly composed of a traction machine, a control cabinet, an elevator car body, guide rails, etc. Downlink; In order to realize uplink and downlink and install related equipment, elevator shafts will be built in buildings or other places where van elevators are used to achieve smooth operation. [0003] The uplink and downlink of van elevators are generally achieved by mechanical traction, and the structure is relatively complex. Due to problems such as the use environment, cycle, equipment aging, and quality, it will cause the elevator car body to fall without constraints or limited constraints, which is relatively complex. Serious security issue. ...

[0003] The uplink and downlink of van elevators are generally achieved by mechanical traction, and the structure is relatively complex. Due to problems such as the use environment, cycle, equipment aging, and quality, it will cause the elevator car body to fall without constraints or limited constraints, which is relatively complex. serious safety issue

In the prior art, in order to solve the serious danger to the passengers caused by the rigid bottoming of the elevator car body (directly falling to the bottom of the hoistway), a buffer device is installed at the bottom of the hoistway; the buffer device is a hydraulic buffer for high-speed elevators, and generally The structure of the buffer spring is adopted, and this consideration is mainly the relationship between the elastic coefficient of the spring, the stroke and the elevator car body. Therefore, high-speed elevators cannot use springs with a large elastic coefficient, otherwise there will be obvious rigid bottoming feeling. resulting in accidents; the main thing is that the above-mentioned buffer structure is not adaptable according to the whereabouts of the elevator car body, so it cannot be buffered according to the falling situation
