Novel bridge construction anti-falling device

Abstract

The invention discloses a novel bridge construction anti-falling device which structurally comprises two protective shell covers, two baffles, fixing screw holes, a retractable limiting cavity, a deformable sliding rod, a fixing thread, a locking nut, a welding spacer, an initial end welding ring, a terminal welding ring, a strong spring, a fixing sleeve and an expansion and contraction movable joint. The protective shell covers are arranged on the outer side surfaces of the baffles correspondingly, and flange plates are arranged at an inner end openings of the protective shell covers; and thebaffles are evenly provided with the four fixing screw holes in a rectangular mode at equal intervals, and the fixing screw holes and the baffles are of an integrally-formed structure. The novel bridge construction anti-falling device has the beneficial effects that by enhancing the connecting firmness between the bridge construction anti-falling device and a bridge, the maximum bearable force ofthe device is increased, the bridge construction anti-falling device is protected, and the service life of the novel bridge construction anti-falling device is prolonged accordingly; and meanwhile, bridge collapse is effectively avoided, the bridge is protected, and thus the cost in the aspect of bridge maintenance is reduced.

Description

technical field [0001] The invention is a novel bridge construction fall prevention device, which belongs to the technical field of bridge construction equipment. Background technique [0002] Bridge construction refers to the process of building a bridge according to the design content; it mainly refers to bridge construction technology, construction organization, construction management, construction quality, etc. [0003] The prior art discloses application number CN201720121621.4, a bridge construction fall prevention device. The invention discloses an anti-drop device for bridge construction, which comprises a fixed frame body, a horizontal plate, a sliding rod, a fixed pin and a winch. A support base is welded on the fixed frame body, and a first foot is fixedly arranged inside the fixed frame body. Step on the pedal, a handrail bar is installed on the first foot pedal, the two ends of the horizontal plate are welded on the fixed frame, the upper and lower ends of the...
