[0006] 2. When the elevator control system only detects the star-sealing contactor, after the star-sealing contactor is damaged, it has not been replaced due to various reasons
[0008] To sum up, through the detection points reserved on the elevator control system to detect the action state of the star-sealing contactor, there are detection distortions, which cannot truly reflect whether the star-sealing contactor is in normal operation and whether it is in an effective state

Embodiment Construction
[0045] Embodiments of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art would recognize that the described embodiments can be modified in various ways or combinations thereof without departing from the spirit and scope of the invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims. Also, in this specification, the drawings are not drawn to scale, and like reference numerals denote like parts.
[0046] Such as figure 2As shown, the counterweight 20 and the car 10 are respectively at the two ends of the guide wheel 40 , and the buffer 30 is below the counterweight 20 . According to the national standards of the elevator industry, when the elevator is leveling on the top floor, there is a certain buffer space between the bottom of the counterweight side and the buffer 30, because even if there is too fast acceleration in this area, the buf...

The invention discloses a star sealing contactor detection method and device for an elevator. The method comprises the steps that a lift car is controlled to stop on a top flat layer, and an elevator band-type brake device is opened; timing is conducted while the opening signal of the band-type brake device is received, and the real-time speed or the real-time acceleration of rotation of the traction machine when the elevator slides upwards is monitored in real time within the preset time; if the preset time is not reached, the real-time speed is larger than the preset speed or the real-time acceleration is larger than the preset acceleration, the elevator control system judges that the star sealing contactor is in a non-effective state; and if the real-time speed is not greater than the preset speed or the real-time acceleration is not greater than the preset acceleration after the preset time is reached, judging that the star sealing contactor is in an effective state. According to the invention, the buffer idle stroke between the counterweight and the buffer is utilized, so that the no-load elevator slides upwards to simulate the sliding of the elevator under the fault condition, whether the star-sealing contactor is in an effective state is judged through the speed or acceleration signal, and the defect that the star-sealing contactor is detected by adopting a conventional contact on-off detection mode is avoided.
Description
technical field [0001] The invention relates to the technical field of elevator detection, in particular to a detection method and device for a star-blocking contactor for an elevator. Background technique [0002] As a tool for vertical transportation of people and goods, elevators have become an indispensable part of building construction, and elevator safety has received more and more attention. To ensure safety. Modern elevators already have very mature protection measures, and the elevator star-blocking contactor is one of the measures. [0003] At present, the devices used to protect the elevator from stalling on the traction drive passenger elevator include brake arms, safety gears and upward overspeed protection devices. Normally, when the elevator stops running or loses power, the brake arm of the traction machine automatically locks the drive host mechanically. When the elevator is overspeeding downward, the brake arm is locked by the action of the speed limiter...
