Problems solved by technology

[0004] The purpose of the present invention is to solve the problems of the above-mentioned prior art. The existing elevator leveling unlocking devices often need to be driven by electricity. In the state of power failure, it is quite difficult to unlock the leveling. Generally, external repair personnel are required to board the elevator. The car starts to unlock, but there is a huge problem for the self-rescue of the elevator personnel. The main problem is the time difference. Since the leveling unlock cannot be performed, the user in this application cannot open the car door and is trapped in the car. The problem is to provide an elevator leveling unlocking device and its control method that can operate safely when the power is on, and can automatically unlock the leveling when the power is off.

Embodiment 1

[0029] A kind of elevator leveling unlocking device (see attached figure 1 ), is controlled by the elevator control system, cooperates with the linkage shaft in the door machine system, and is installed on the top 11 of the elevator car. Each leveling position in the hoistway is equipped with a non-contact power drive device. The elevator leveling The unlocking device includes an electric drive device, a non-contact power action device, a locking lever 1, a locking lever hinge, a locking lever fixing part 2, a linkage lever 6, a driving motor 8, a linkage lever fixing part 7 and a linkage lever driving part 9 , the locking rod fixing part is fixed on the top of the elevator car, the locking rod is connected to the locking rod fixing part through a locking rod hinge, and the outer side of the locking rod corresponds to the position of the non-contact power drive device and the non-contact power The action device is connected, the inner side of the locking rod is connected with ...

Embodiment 2

[0038] This embodiment is basically the same as Embodiment 1, except that the non-contact power drive device does not use the above-mentioned flat layer permanent magnet, but other mechanical mechanisms: such as a hair dryer, etc., and the electric drive device does not use The electromagnet push rod adopts many replacement forms, which can be electric push rod, hydraulic push rod, other gear mechanical mechanisms, etc. In this embodiment, a hydraulic push rod is used. If the non-contact power action device is the top The leveling push rod that is equipped with fixed permanent magnet is exactly in order to cooperate with fixed permanent magnet, but can not choose the best solution in the present embodiment, for example, the leveling push rod of the top configuration that receives blowing device can be the leveling push rod pole.

Embodiment 3

[0040] In this embodiment, instead of using a non-contact power drive device, a contact power drive device can be selected, and the raised bumps can be entered. When leveling, the locking lever can be pushed by the bumps to unlock the leveling. the goal of. However, compared with Embodiment 1, this embodiment has a huge problem, that is, noise will be generated every time the flat layer is reached, and the operation effect is relatively poor.

[0041] A control method for an elevator leveling unlocking device, suitable for the above-mentioned elevator leveling unlocking device,

[0042] When the elevator leveling unlocking device is powered on, the electric drive device is controlled by the elevator control system. If the elevator control system receives the elevator door opening instruction, step S1 is executed; if the elevator control system does not receive the elevator door opening instruction, then step S2 is executed. When the elevator is in the state of power failure, ...

Abstract

The invention relates to an elevator leveling unlocking device. The defects in the prior art are overcome. According to the technical scheme, the elevator leveling unlocking device comprises an electric driving device, a non-contact power action device, a locking rod, a locking rod hinge, a locking rod fixing piece, a linkage rod, a driving motor, a linkage rod fixing piece and a linkage rod driving piece. The locking rod fixing piece is fixed to the top of an elevator car. The locking rod is connected with the locking rod fixing piece through the locking rod hinge; the position, correspondingto the non-contact power action device, of the outer side of the locking rod is connected with the non-contact power action device; the inner side of the locking rod is connected with the electric driving device, one end of the locking rod abuts against the side wall of the second end of the linkage rod, the linkage rod is perpendicular to the locking rod, the linkage rod fixing piece is fixed tothe top of the elevator car, the linkage rod fixing piece is hinged to the middle of the linkage rod, and the first end of the linkage rod is connected with the driving motor through the linkage roddriving piece.

Description

technical field [0001] This patent relates to the technical field of elevator safety equipment, in particular to an elevator leveling unlocking device and a control method thereof. Background technique [0002] Existing elevator leveling unlocking devices often need to be driven by electricity. In the state of power failure, it is quite difficult to unlock the leveling. Generally, it is necessary for external repair personnel to board the elevator car to start unlocking, but this is very difficult for elevator personnel. There is a huge problem of self-rescue in this application, and the main problem is exactly the time difference. Since the leveling unlock cannot be carried out, the user in this application cannot open the car door and is trapped in the car. [0003] Chinese invention patent, the application date is January 28, 2016, which discloses a protective device for preventing accidental movement of the elevator car. Install a protective device to prevent the elevat...
