Problems solved by technology

[0003] Due to the poor awareness of safety accidents on the construction site, sometimes in order to speed up work efficiency, many people will take a construction elevator to work on the floor at the same time. It is not uncommon to take the same construction elevator on the same construction elevator, which leads to the occurrence of heavy loads on the construction elevator. It is not uncommon to see falling accidents due to overloading of the construction elevator. Under heavy working conditions, and the goods often impact the construction elevator, the construction elevator is very easy to damage and fall, and there are often people and goods walking together on the construction site. When the construction elevator is damaged and falls, it will bring workers to great harm

Embodiment 1

[0021] refer to figure 1 , an emergency fall prevention system for building construction elevators, including an elevator body 2 located in an elevator protective shell 1, a base 4 is fixedly connected to the lower end of the elevator body 2, a cylindrical cavity 5 is opened on the base 4, and the inner wall of the cylindrical cavity 5 is slidingly connected. Sliding board 6, the lower end of the sliding board 6 is fixedly connected with the vertical bar 7, and the upper end of the sliding board 6 is fixedly connected with the annular air bag 8, the annular air bag 8 can only be contracted in the vertical direction, the annular air bag 8 is filled with magnetorheological fluid, magnetorheological The liquid is a controllable fluid, which is a suspension composed of tiny soft magnetic particles with high magnetic permeability and low hysteresis and a non-magnetic liquid. This suspension presents a low-viscosity Newtonian fluid under zero magnetic field conditions. characteristi...

Embodiment 2

[0027] refer to Figure 2-3, different from Embodiment 1, the lower end of the base 4 is symmetrically provided with a through hole 20 communicating with the through groove 15, and the lower end of the cross bar 16 is rotatably connected with a movable column 19 that cooperates with the through hole 20, and the movable column 19 is located near the through groove 15. On one side of the notch, the opposite side wall of the through hole 02 is provided with a chute 21, and the inner wall of one of the chute 21 is elastically connected with a movable plate 22 by a second spring 23, and the side wall of the movable plate 22 is provided with a chute to cooperate with the side wall of the movable column 19. The notch makes the side wall of the movable plate 22 fixedly connected with a traction rope 24, and the traction rope 24 runs through the side wall of the base 4 and is fixedly connected with a pull rod. When the elevator body 2 falls, the rotating cross bar 16 drives the movable ...

Abstract

The invention discloses an emergency fall prevention system for a building construction elevator, which comprises an elevator body located in an elevator protective shell, the lower end of the elevator body is fixedly connected with a base, and a cylindrical cavity is opened on the base, and the inner wall of the cylindrical cavity slides A slide plate is connected, the lower end of the slide plate is fixedly connected with a vertical rod, the upper end of the slide plate is fixedly connected with an annular air bag, the annular air bag is filled with magnetorheological fluid, and a driving device for driving the slide plate is installed on the base. In the present invention, the airfoil plate, cross bar, vertical bar, slide plate, annular airbag and magnetorheological fluid are arranged. When the elevator body falls, the airfoil plate drives the cross bar to slide to make the slide plate squeeze the annular airbag, so that the inside of the annular airbag The magneto-rheological fluid is carried into the groove, and the slide plug is pushed to make the brake block cooperate with the brake groove, and the elevator body is forced to stop.

Description

technical field [0001] The invention relates to the technical field of building construction elevators, in particular to an emergency fall prevention system for building construction elevators. Background technique [0002] The building construction elevator is composed of several parts such as the car, the driving mechanism, the attached wall, the fence, and the electrical system. [0003] Due to the poor awareness of safety accidents on the construction site, sometimes in order to speed up work efficiency, many people will take a construction elevator to work on the floor at the same time. It is not uncommon to take the same construction elevator on the same construction elevator, which leads to the occurrence of heavy loads on the construction elevator. It is not uncommon to see falling accidents due to overloading of the construction elevator. Under heavy working conditions, and the goods often impact the construction elevator, the construction elevator is very easy to ...
