Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to an elevator rescue leveling indicating device. Background Art

[0002] An elevator is a vertical lift powered by an electric motor and equipped with a box-shaped cabin. It is used to carry people or goods in multi-story buildings. When the elevator fails or a power outage occurs during operation, the car will suddenly stop rising or falling, causing the car to be higher or lower than the level area. In order to improve the safety of rescue during rescue, the elevator needs to be turned to raise or lower the car so that the car is level with the level area.

[0003] During the elevator rescue process, dedicated personnel will operate the elevator to crank the car, release the brake, and let the car slide up or down to the nearest floor to release the passengers. During the car sliding process, the position of the car cannot be accurately judged. The car may slide out of the level area or the car is higher than the level area, so the elevator needs to be cranked again, which affects the rescue speed and increases the panic of the passengers. To solve the above problems, this application proposes an elevator rescue leveling indicator device. Utility Model Content

It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0026] like Figure 1-4 As shown, the utility model proposes an elevator rescue leveling indicating device, comprising a waiting leveling 1, a guide rail 2, a car 3 and a guide wheel 4, wherein the waiting leveling 1 is equidistantly arranged on one side of the guide rail 2, the guide wheel 4 is rotatably arranged on the surface of the car 3, the car 3 is in the inner cavity of the guide rail 2, a top plate 5 is welded on the top surface of the guide rail 2, a fixing frame 6 is welded on the upper surface of the top plate 5, and a rescue leveling indicating mechanism is installed on the surface of the fixing frame 6;

When the car 3 is raised or lowered, the leveling sensor 16 passes through the inner cavity of the mounting row 12.

[0029] It should be noted that the car 3 moves up and down along the guide rail 2 under the cooperation of the guide wheel 4. When the car 3 is rising or falling, the leveling sensor 16 will pass through the installation row 12. When the elevator car 3 is running, if the elevator suddenly loses power or fails, the dedicated personnel will release the brake to make the car 3 slide up or down to the nearest waiting level 1 to release the passengers. When controlling the car 3 to slide up or down, the leveling sensor 16 installed on the car 3 will be inserted into the installation row 12.

When the elevator is out of power, the elevator rescue leveling indicator device can still work normally, which can improve the reliability of personnel rescue.

[0032] The working principle and use process of the utility model are as follows: the car 3 moves up and down along the guide rail 2 under the cooperation of the guide wheel 4. When the car 3 is rising or falling, the leveling sensor 16 will pass through the installation row 12. When the elevator car 3 is running, the elevator suddenly loses power or fails, and the dedicated personnel release the brake to make the car 3 slide up or down to the nearest waiting level 1 to release the passengers. When controlling the car 3 to slide up or down, the leveling sensor 16 installed on the car 3 will be inserted into the installation row 12. When the car 3 is rising or falling, the leveling sensor 16 will first meet the upper proximity magnetic isolation plate 14 or the lower proximity magnetic isolation plate 15 in the installation row 12, and the upper proximity indicator light 8 or the lower proximity indicator light 9 on the fixing frame 6 will light up, which can be used for the dedicated personnel. The dedicated personnel will serve as a reminder. The full-time personnel will slow down the control speed of the elevator's ascent or descent. When the leveling sensor 16 moves to the stop magnetic isolation plate 13, the stop indicator light 7 will light up, and the full-time personnel can quickly control the elevator to stop rising and falling, so that the bottom of the inner cavity of the car 3 is flush with the upper surface of the waiting leveling floor 1. The position of the car 3 is accurately controlled so that the passengers in the car 3 can be quickly released, which can improve the rescue efficiency and safety during rescue. The stop indicator light 7, the upper approach indicator light 8, the lower approach indicator light 9, the stop magnetic isolation plate 13, the upper approach magnetic isolation plate 14, the lower approach magnetic isolation plate 15 and the leveling sensor 16 are connected to the emergency power supply 10.
