Elevator limiting device

Abstract

The invention discloses a limit device for an elevator, which comprises a car body, a car frame and guide rails, the car frame is fixed on the outer wall of the car, the car frame is movably connected with the guide rail through guide shoes, and the guide shoes are respectively fixed On both sides of the car frame, the guide shoe is matched with the guide rail. There is a car door at the entrance of the car body, and the car door is movably connected to the car frame. There are several vertical grooves on the side of the guide rail close to the car frame, and a limit device is provided on the bottom surface of the car frame. The limit device includes a limit rod, a fixed sleeve, a driven gear, a driving gear and a swing rod. The bottom surface of the sleeve is fixed on the top surface of the car frame, the limit round rod slides and penetrates in the fixed sleeve, and the driving gear and the driven gear are movably fixed on the top surface of the car frame respectively. The beneficial effect is: the whole operation process is completed with the opening and closing of the car door, does not affect the normal use of the elevator, eliminates existing safety hazards, and ensures the personal safety of passengers at all times.

Description

technical field [0001] The invention relates to the technical field of elevator safety, in particular to an elevator limiting device. Background technique [0002] In recent years, with the advancement of urbanization and the improvement of residents' living standards, elevators have become an indispensable vertical transportation tool in people's production and life. In 2013, the total output of elevators in my country reached 579,700 units, a year-on-year increase of 9.58%. China has become the country with the highest elevator output in the world, accounting for more than 60% of the global total. With the explosive growth of elevators, the number of elevator accidents remains high. Although safety devices have been installed inside elevators, they are not comprehensive. When the elevator is loading and unloading passengers, the elevator suddenly lands and the safety device starts. However, in order to cause harm to the human body, the accident duration can only be shorte...
