Problems solved by technology

[0010] It can be seen that the UCMP in the prior art is a system that "stops movement" and has the technical attribute of "post-processing", and this attribute means that the car has started to move unexpectedly, which will bring a certain security threat to the car users and psychological shadow, at the same time, it will also cause certain damage to the car, which is not conducive to safety protection and maintenance

specific Embodiment approach

[0095] Such as Figure 5(a)-Figure 5(e) As shown, another specific embodiment of the present invention uses flexible (rope) transmission.

[0096] The driving car door connecting rod 5 is connected with the car door 7 (left and right symmetry), and under the drive of the door opener, the driving car door connecting rod 5 drives the car door 7 to open and close the car door. Simultaneously, drive the car door connecting rod 5 to be connected with the transmission rope 17 (not limited to steel wire rope). Drive rope 17 is connected with slide lock end 9 by turning or turning back of pulley I, pulley II, pulley III, pulley IV. When the car door was closed, the car door connecting rod 5 was driven to pull the transmission rope 17, and the transmission rope 17 connected the sliding lock head 9 to move horizontally towards the car center direction, and the compression spring 16 was compressed. After the car door 7 is completely closed, the sliding lock 9 arrives at the non-action ...

Abstract

The invention discloses a non-stopping type unintended car movement protection mode and device and a driving method of the device; door opening and closing processes are associated with UCMP (unintended car movement protection); upon opening of an elevator door, a protective part arranged on a car is driven by a door system and horizontally pushed to a predetermined positon of a retaining device arranged on the wall of a well and kept retained, and the protective part is not reset until the elevator door is closed. Once unintended car movement occurs, the protective part is limited by the retaining device so that a car cannot be moved, protection may be provided before the unintended car movement, stopping type control mode is not required, the service life of the car can be extended, and safety of use of the car can be guaranteed.

Description

technical field [0001] The invention relates to a non-stop car accidental movement protection method, device and driving method thereof. Background technique [0002] Unexpected movement of the elevator car is a very dangerous phenomenon. People or things entering and leaving the car are very likely to be cut and hurt by the sudden movement of the car in the gap between the metal frame of the car door and the building door opening. Such accidents occur from time to time with the large number of applications of elevators. [0003] Therefore, the elevator industry has long paid attention to and devoted itself to researching and solving measures to prevent accidental movement of the car or to stop the movement from a technical point of view. EN81-2 / 1:1998 / A3 (European Standardization Committee Elevator Manufacturing and Installation Safety Standard) proposed the technical requirements of UCMP, EN81-20 / 50:2014 reassessed the elevator risk, in EN81-2 / 1:1998 / Adjustments were ma...
