Problems solved by technology

[0004] In the existing buffer technology, the above two kinds of elevator buffers all adopt the contact deceleration method, which requires the material of the buffer to have high strength. When the elevator car collides with the buffer, due to the high strength of the buffer May cause deformation of the elevator car body, and cause injury to people in the elevator

Embodiment 1

[0044]Lenz's law is the specific embodiment of the law of conservation of energy in the phenomenon of electromagnetic induction, which can be expressed as: the effect of the induced current always hinders the cause of the induced current, or because the induced current has such a direction, and the magnetic field of the induced current always hinders A change in magnetic flux that causes an induced current. Let's take copper wire pipe and magnet as an example to illustrate Lenz's law:

[0045] When a magnet keeps approaching the copper wire tube or passing through the copper wire tube during the falling process, that is, when relative motion occurs, it will be hindered by the copper wire tube based on Lenz's law, and the force generated by the hindering effect can realize the deceleration effect of the magnet . figure 1 A structural schematic diagram showing the relative motion process of the copper wire tube and the magnet. Here, taking a layer of coil in the copper wire tu...

Abstract

The invention relates to an electromagnetic buffering lift and a lift monitoring system and relates to the technical field of lift devices. The electromagnetic buffering lift comprises a lift shaft, a lift car and a buffering device, wherein the lift car and the buffering device are arranged in the lift shaft. The buffering device comprises deceleration coils and deceleration magnets. The deceleration coils are arranged at the bottom of the lift car. The deceleration magnets are arranged on the inner wall of the lift shaft. According to the electromagnetic buffering lift and the lift monitoring system, the structure is simple, non-contact type deceleration is achieved through the Lenz's law, the influence of collision on the lift car can be effectively avoided, and then people in the lift car can be prevented from being hurt; and in addition, the deceleration effect and the falling speed of the lift car are in direct proportion, so that the same lift device can be adapted to different falling heights, and the material problem of a buffer does not need to be considered.

Description

technical field [0001] The invention relates to the technical field of elevator equipment, in particular to an electromagnetic buffer elevator and an elevator monitoring system. Background technique [0002] The elevator buffer is a very important part of the elevator safety system. When the elevator fails or the accident causes the elevator to squat, the elevator buffer can play a buffering role, thereby relieving the elevator or people in the elevator from being directly injured. hit. [0003] There are two main types of buffers for elevators: energy storage buffers and energy consumption buffer elevators. The first type: energy storage type buffer refers to the spring buffer, the main component is a coil spring made of round or square steel wire. Due to the consideration of the elastic coefficient of the spring and the relationship between the stroke and the elevator box, the energy storage buffer can only be used for elevators whose rated speed does not exceed 1.0m / s. ...
