Anti-pinch passenger elevator with quick response

Abstract

The invention discloses an anti-pinch passenger elevator with quick response. The anti-pinch passenger elevator with quick response comprises an elevator car (2) installed in an elevator car frame (1)and provided with two car doors (3); each car door (3) is provided with a movement prevention device (4), a groove A (5) and a groove B (6); a capacitor screen A (7), a buffer spring A (8) and a buffer pad A (9) are installed in each groove A (5); a capacitor screen B (10), a buffer spring B (11) and a buffer pad B (12) are installed in each groove B (6); safe light curtain projectors (13) are arranged on the two sides of the grooves A (5), and safe light curtain light receptors (14) are arranged on the two sides of the grooves B (6); the elevator car (2) is provided with door opening guide rails (15); and a moving base (16) and a sensor set are installed on the door opening guide rails (15). According to the anti-pinch passenger elevator with quick response, the sensitivity and safety can be improved, and the anti-pinch passenger elevator further has the advantages of preventing the car doors from being opened by accident and being long in service life and convenient to install.

Description

technical field [0001] The invention relates to a passenger elevator, in particular to a rapid-response anti-pinch passenger elevator. Background technique [0002] At present, as the building floors such as residential areas, shopping malls, and office buildings are getting higher and higher, the use of elevators is becoming more and more extensive. Existing elevators are commonly used as daily life tools in high-rise buildings. Infrared light curtains are generally installed as anti-pinch devices to prevent passengers from being injured when the elevator doors are closed when passengers enter or leave the elevator. However, using infrared to sense passengers or objects, there will be certain In the blind area, some accidents will still occur, and after long-term use, the sensitivity of the induction will be reduced, and the safety will be poor; at the same time, although the existing elevator door opening and closing system has been developed into a permanent magnet synchr...

AI Technical Summary

Problems solved by technology

Existing elevators are commonly used as daily life tools in high-rise buildings. Infrared light curtains are generally installed as anti-pinch devices to prevent passengers from being injured when the elevator doors are closed when passengers enter or leave the elevator. However, using infrared to sense passengers or objects, there will be certain In the blind area, some accidents will still occur, and after long-term use, the sensitivity of the induction will be reduced, and the safety will be poor; at the same time, although the existing elevator door opening and closing system has been developed into a permanent magnet synchronous door machine system, the elevator The car door of the elevator is not completely closed during use. When the elevator stops due to a fault, the people in the elevator are likely to rip the door to survive, resulting in people falling to death. There is a safety hazard that the elevator car door is accidentally opened.

Therefore, the existing passenger elevators have the problems of poor sensitivity, low safety and the car door being accidentally opened.
