The invention relates to the technical field, in particular to a rescue control method for a machine room-less elevator, a machine room-less elevator and a rescue auxiliary device.
Background
The superior well size of the elevator without the machine room is more and more favored by users, and along with the continuous increase of the application range of the elevator without the machine room, the rescue problem when the elevator without the machine room breaks down is more and more emphasized.
Because no computer lab elevator does not set up the computer lab, the host computer is placed in the well, consequently can't use when having the computer lab elevator in the past, use when breaking down and carry out the rescue mode of barring operation to the host computer at the computer lab. When the elevator without the machine room breaks down, the lift car is often required to slide to the door opening area, and then the door opening rescue work is carried out. However, when the contracting brake is opened, the car cannot slide due to the fact that unbalanced moment cannot be generated when the load and the weight of the counterweight of the car are in a balanced state, and therefore the rescue difficulty is increased.

Because no computer lab elevator does not set up the computer lab, the host computer is placed in the well, consequently can't use when having the computer lab elevator in the past, use when breaking down and carry out the rescue mode of barring operation to the host computer at the computer lab. The elevator without the machine room generally uses a mechanical or electrical mode to open a main machine internal contracting brake, and utilizes the characteristic that the load of a counterweight and a lift car is unbalanced to enable the lift car to slide upwards or downwards, so that the lift car enters a door opening area and then opens a door to save people. But when appearing being in balanced state to heavy and car load, even open the band-type brake, the car also can't slide, leads to the rescue degree of difficulty to increase.
Therefore, in one embodiment, the rescue auxiliary device can generate pulling force to assist the car to slide downwards, and is beneficial to improving the rescue efficiency and safety of the elevator without the machine room.
