Elevator anti-falling device for construction site

Abstract

The invention discloses an elevator anti-falling device for a construction site. The elevator anti-falling device comprises two base plates which are parallelly arranged; an elevator is arranged between the two base plates; two limiting rail strips are fixedly mounted at each of the two side edges of the elevator; the two limiting rail strips located at the same side edge of the elevator are distributed in an axial symmetry mode with respect to the elevator longitudinal center line where the two limiting rail strips are located; a fixed plate and a moving plate are arranged between every two limiting rail strips, and the moving plates are located below the fixed plates; the upper ends of the moving plates and the lower ends of the fixed plates are fixedly connected through spring rods; sliding grooves are formed in the middles of the opposite sides of every two limiting rail strips correspondingly; and the two sides of the moving plates are fixedly connected with sliding blocks correspondingly, and the thickness of the sliding blocks is equal to the groove width of the sliding grooves. The elevator anti-falling device for the construction site is pushed through worm wheels and leadscrews, a barrier layer is arranged on a nearest elevator room during elevator falling, the falling elevator is blocked and prevented from falling, and immeasurable losses caused by excessively largegravitational potential energy are avoided.

Description

technical field [0001] The invention belongs to the technical field of construction site protection equipment, and in particular relates to a construction site elevator anti-falling device. Background technique [0002] The traditional anti-falling equipment for construction site elevators is generally equipped with a shock-absorbing buffer device on the floor of the elevator. Although the construction is simple and easy to install and disassemble, its anti-fall performance is poor, especially when the floor is high, the damage to the elevator due to the huge gravitational potential energy is inestimable, so it is necessary to design a construction site elevator with high anti-fall performance drop device. Invention content: [0003] The object of the present invention is to provide a construction site elevator anti-falling device in order to solve the above problems, which solves the problem of poor anti-falling performance of the existing construction site anti-falling ...
