Problems solved by technology

The main safety hazards of the elevators in use in my country are "car door opening and walking" and "car stalling or falling out of control or falling to the top", and the reasons for these safety hazards are mainly due to the existing elevator controller, which cannot effectively implement Unexpected car movement protection (UCMP)
Although the elevator controllers of some manufacturers can realize the UCMP function, they need to be equipped with a monitoring unit and an execution unit. According to national standards, the monitoring unit needs to be type-tested separately, and the monitoring unit also needs to be equipped with a separate detection device. Matching use, which not only increases the cost of product manufacturing and certification, but also cannot allow the monitoring unit to be used alone, and the application range is narrow
Moreover, if the existing elevator controller is under stress for a long time, it will easily age and work unreliably, which will affect product quality.

Embodiment

[0035] Example: such as Figure 1-5 As shown, the present invention provides a first embodiment of an elevator controller that prevents accidental movement, which brakes the wire rope 2 or the guide rail bidirectionally, and includes: at least one pair of fixed clips 10, which can be opposite to the corresponding fixed clips 10 At least one movable clamping block 20 that reciprocates and is located on one side of the steel wire rope 2 or the guide rail, the frame 1 located on the outside of the fixed clamping block 10, and the friction plate 30 arranged on the inside of the movable clamping block 20 can be in contact with the steel wire rope 2 or the guide rail The trigger piece, the pulley bar 50 arranged in the center of the trigger piece, the connecting rope 60 connected to the pulley bar 50 at one end, the deflectable actuating lever 70 connected with the other end of the connecting rope 60, and the other end of the actuating lever 70 are locked An unlocking lever 80 that ...

no. 4 example

[0043] On the basis of the first embodiment, the present invention also provides a fourth embodiment of an elevator control method for preventing accidental movement, which includes the following steps:

[0044] S1: provide at least one pair of fixed clips, at least one movable clip that can reciprocate relative to the corresponding fixed clips and is located on one side of the wire rope or guide rail, and a trigger;

[0045] S2: Initially, there is a gap between the trigger and the wire rope or guide rail;

[0046] S3: When the elevator door is opened, the drive unit drives the trigger to contact the wire rope or guide rail. If the trigger does not move, it will end until the end. If the trigger does move, go to step S4;

[0047] S4: When the steel wire rope or the guide rail moves unexpectedly, prompt the trigger to act and enter step S5;

[0048] S5: after the action of the trigger, the movable clamping block is driven towards the steel wire rope or the guide rail for clam...

Abstract

The invention discloses an elevator controller and method for preventing accidental movement, which comprises: at least one pair of fixed clips, at least one movable clip that can reciprocate relative to the corresponding fixed clips and is located on one side of the wire rope or guide rail, and a trigger A part, wherein the trigger part is triggered by accidental movement of the wire rope or guide rail and then drives the movable clamping block to perform clamping action towards the wire rope or guide rail. The present invention performs braking and self-locking actions when and only when it is in an unexpected moving situation, and is in an unlocked state in other situations, so as to prevent the elevator controller from being under stress for a long time, with high reliability, long life, low cost and convenient maintenance.

Description
