Embodiment 1

[0030] refer to Figure 1-4 , the brake disc type emergency braking system of the vertical lift elevator, including the signal triggering device installed outside the bridge compartment 8, the control system and the actuator, the signal triggering device includes the paddle installed on the bridge compartment 8 and fixed on the inner wall of the elevator shaft The fixed part, and as the bridge compartment 8 goes down, the paddle touches the fixed part on the inner wall of the elevator shaft. The fixed part is a series of protrusions that can touch the paddle, and is set on the inner wall of the elevator shaft from top to bottom according to the fixed part. Installed at intervals, the interval distance can be reduced in the section where the lowermost car runs at a slow speed.

[0031] The paddle moves to connect the circuit, and the generated electrical signal is connected to the control system to connect the circuit. The control system analyzes the signal after receiving the ...

Embodiment 2

[0047] The difference from the embodiment is that in this embodiment, the signal triggering device can also adopt a non-contact mechanism. The non-contact mechanism includes a light source and a photosensitive circuit installed on the car, and a series of When the mirror and the bridge compartment 8 pass through the position of the mirror during operation, the light emitted by the light source is reflected by the mirror and irradiates the photosensitive element to generate an electrical signal, which is connected to the control system to switch on the circuit.

[0048] The non-contact mechanism can avoid the rigid contact of the mechanism, making the equipment more durable.

[0049] The present invention detects the falling acceleration of the elevator car 8. When an abnormal acceleration is detected, the safety hook installed on the inner wall of the elevator shaft grabs the steel ring 5 and pulls the wire rope out of the wire rope winding 3. During the process of pulling out ...

Abstract

The invention discloses a brake disc type emergency braking system for a vertical lifting elevator, which includes a signal trigger device installed outside the bridge compartment, a control system and an executive mechanism. The signal trigger device includes a paddle installed on the bridge compartment and The fixed part on the inner wall of the shaft, and when the bridge car goes down, the paddle touches the fixed part on the inner wall of the elevator shaft, the paddle moves to connect the circuit, the generated electrical signal is connected to the control system to connect the circuit, and the generated electrical signal is connected to The control system analyzes the signal after receiving the signal, and sends a braking command when an abnormal situation occurs. The present invention can detect the falling acceleration of the elevator car, and when an abnormal acceleration is detected, the safety hook installed on the inner wall of the elevator shaft grabs the steel ring and pulls the wire rope out of the wire rope winding. Brake discs and friction plates provide braking force to brake the axle compartment, thereby ensuring the safety of passengers.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a brake disc emergency braking system of a vertical lift elevator. Background technique [0002] A double-deck elevator with two elevator cars up and down in the car frame is constructed such that a driving mechanism is provided on the upper part of the upper car, and the lower part of the upper car connected to the driving mechanism by a sling and the lower car Pulleys are provided at the lower part of the car, and a sling is wound around these pulleys, and the upper car and the lower car are driven by a drive mechanism. [0003] In the prior art, as a detection device for detecting the fall of the elevator car when the sling for driving the upper car and the lower car is cut, applied to the double-deck elevator having the above-mentioned structure, for example, it is disclosed in Patent Document 1 A solution is proposed, which is provided with detection rollers in contact wi...
