Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing elevator leveling unlocking linkage device of the above-mentioned prior art often needs to be driven by electricity. In the state of power failure, it is quite difficult to unlock the leveling. The elevator 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 To solve the problem, provide an elevator leveling unlock linkage 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 unlock linkage device (see attached figure 1 , attached figure 2 , attached image 3 And attached Figure 4), controlled by the elevator control system, installed on the top 11 of the elevator car, and cooperate with the door machine drive motor 32 of the door machine system and the linkage 33 in the landing door system, including the linkage shaft 31, shaft auxiliary equipment, leveling unlocking device and an elevator anti-mis-movement device, the hoistway auxiliary equipment includes an anti-mis-movement pin hole configured at each leveling position and a non-contact power drive device configured at each leveling position, the leveling position The layer unlocking device includes a leveling unlocking part, a linkage rod 6 and an unlocking linkage part. The controlled driving end of the leveling unlocking part is aligned with the non-contact power drive device in the hoistway auxiliary equipment, and the leveling unlocking part The lock...

Embodiment 2

[0036] 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

[0038] 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.

[0039] A control method for an elevator leveling unlocking linkage device, which is suitable for the above-mentioned elevator leveling unlocking linkage device, characterized in that it includes an unlocking linkage step in a powered state and an unlocking linkage step in a power-off state, if the elevator as a whole In the power-on state, execute the unlocking linkage steps in the power-on state, and if the elevator is currently in a power-off state, execute the unlocking linkage steps in the power-off state,

Abstract

The invention relates to an elevator leveling unlocking linkage device. The defects in the prior art are overcome. According to the technical scheme, the device comprises a linkage shaft, shaft auxiliary equipment, a leveling unlocking device and an elevator anti-misplacement device. The shaftway auxiliary equipment comprises an anti-misplacement pin hole formed in each leveling position and a non-contact power driving device arranged at each leveling position. The leveling unlocking device comprises a leveling unlocking part, a linkage rod and an unlocking linkage part; the controlled drivingend of the leveling unlocking part is aligned with the non-contact power driving device in the shaftway auxiliary equipment; the locking end of the leveling unlocking part is connected with the controlled end of the linkage rod; the driving end of the unlocking linkage part is connected with the tail portion of the linkage shaft through a linkage rod, the front end of the linkage shaft penetratesthrough the portal crane driving motor to be aligned with a linkage piece in the landing door system, the output portion of the elevator anti-misplacement device is aligned with the anti-misplacementpin hole, and the driving end of the unlocking linkage portion and the elevator anti-misplacement device are both electrically connected with the elevator control system.

Description

technical field [0001] This patent relates to the technical field of elevator safety equipment, in particular to an elevator leveling unlock linkage device and a control method thereof. Background technique [0002] Existing elevator leveling unlocking linkage 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 the elevator. There is a huge problem in the self-rescue of personnel, 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 el...
