Abstract
Description
Technical Field
[0001] The invention relates to the field of elevators, and in particular to a passenger elevator safety window with a fire-fighting function. Background Art
[0002] The elevator safety window is installed on the top of the car and is a closed window that opens outward. It can only be opened by installation and maintenance personnel. When the elevator has an accident or a malfunction and stops, it is an emergency exit of the car for rescuing and evacuating passengers. In order to ensure personal safety, non-professionals are strictly prohibited from opening it without authorization. A mechanical switch connected to the electrical safety circuit should be installed on the safety window. When the window sash is opened, the switch of the control circuit can be disconnected to stop the elevator safely. For safety requirements, the safety window must be a safety component that is set to open upward and can only be opened on the top of the car.
[0003] At present, most elevator safety windows are installed on the top of the car. When an emergency occurs and the car door cannot be opened, people trapped in the elevator need to escape from the car through the safety windows. However, since the height of most cars is not less than 3 meters, most people cannot escape from the car smoothly, which increases the difficulty of rescue by firefighters. Summary of the invention
[0004] The purpose of the present invention is to solve the problem that since the height of most elevator cars is not less than 3 meters, most people cannot escape from the elevator cars smoothly, which increases the rescue difficulty of firefighters.
[0005] In order to achieve the above-mentioned object of the invention, the present invention provides the following technical solutions to improve the above-mentioned problems.
[0006] The specific application is as follows:
[0007] A passenger elevator safety window with fire protection function, comprising a car top, a door and window mechanism is arranged in the middle of the car top, the door and window mechanism comprises a through hole opened in the middle of the car top for personnel escape, and two first door and window panels and a second door and window panel are arranged at the bottom of the through hole for blocking the through hole;
[0008] A limiting mechanism is arranged on one side of the top end of the car roof.
[0009] As a preferred technical solution of the present application, sliding grooves are provided on opposite sides of the two first door and window panels, and sliders are slid inside the two sliding grooves, and one end of the two sliders are fixedly connected to the two sides of the second door and window panels (the sliding grooves and the sliders are existing well-known connection technologies, so they are not drawn in detail in the figure).
[0010] As a preferred technical solution of the present application, the first door and window panels and the second door and window panels are both connected with multiple pedals through a rotating shaft and a coil spring. By setting the pedals, after the second door and window panels and the first door and window panels are flipped down, the pedals can be flipped under the action of the coil spring, thereby forming a climbing ladder as shown in the figure, which is convenient for people in the car to climb, and the two first door and window panels are located on both sides and higher than the second door and window panels, so that the space in the car cannot be completely isolated, which is convenient for people in the car to move around, further improving the convenience of rescue.
[0011] As a preferred technical solution of the present application, one side of the second door and window panel and the bottom of the car roof are provided with annular grooves that cooperate with each other to form a complete closed loop. Two magnetic annular clips are slidably connected to the inside of the two annular grooves. The magnetic poles of the two annular clips are the same, so that the two annular clips will not attract each other, thereby allowing the two annular clips to enter different annular grooves.
[0012] As a preferred technical solution of the present application, the limiting mechanism includes two rectangular grooves (not shown in detail in the figure) opened on one side of the top of the car roof, and racks are slidably connected inside the two rectangular grooves.
[0013] As a preferred technical solution of the present application, gears are meshed on the two racks, and the middle part of one side of the two gears is connected to a bracket through a rotating shaft.

[0014] As a preferred technical solution of the present application, a circular shaft for winding a cable (not shown in the figure) is arranged between the two gears, and the circular shaft is connected to a hook via a cable, and the hook is fixedly mounted on one side of the second door and window panel. By setting a limiting mechanism, after people flip open the second door and window panel, the circular shaft is pulled by the cable, and after rotating, it drives the gear and the rack to rotate, so that the guide shoe can increase the friction between the elevator guide rail, making the car more difficult to move when people are performing rescue, thereby improving safety.
[0015] As a preferred technical solution of the present application, the ends of the two racks are fixedly connected with a cross bar, a second cross bar is provided on one side of the cross bar, and a guide shoe used in conjunction with the elevator guide rail is provided on one side of the second cross bar. By providing the guide shoe, the elevator can move more smoothly.
[0016] As a preferred technical solution of the present application, a movable rod is arranged between the cross bar and the second cross bar, and one end of the movable rod is interlaced and connected with the inner part of the cross bar.
[0017] As a preferred technical solution of the present application, a spring is arranged on the outside of the movable rod, and the two ends of the spring are fixedly connected to the opposite sides of the cross bar and the second cross bar respectively. By setting the spring, the guide shoe will not be damaged due to excessive interaction force during the flipping process of the second door and window panel. BRIEF DESCRIPTION OF THE DRAWINGS
