Abstract

The invention provides an anti-falling device for bridge construction. The anti-falling device comprises a mounting box. A first partition is fixed inside the mounting box. A transmission motor is arranged on the upper side of the first partition. Connecting shafts are arranged on the left side and the right side of the transmission motor. A second limiting sliding block is slidably connected in acavity in the low part of each connecting shaft. A second movable rod is fixedly arranged on the low side of each second limiting sliding block. An anti-moving plate is fixedly arranged on the lowersides of the second movable rods. A first limiting sliding block is slidably connected in the cavity in the upper part of each connecting shaft. A first movable rod is fixedly arranged on the upper side of each first limiting sliding block. A lifting plate is fixedly arranged on the upper sides of the first movable rods. First fixing blocks are fixedly arranged on the upper side of the lifting plate. A first guide sliding rod is fixedly arranged between the first fixing blocks. The anti-falling device is reasonable in structural design and convenient to use; when the height of the device is adjusted, the anti-moving plate can be simultaneously driven to support the device and prevent the device from moving; and the device has high stability, good anti-falling effect and high practicability.

Description

technical field [0001] The invention relates to bridge construction equipment, in particular to a bridge construction anti-falling device. Background technique [0002] A bridge refers to a building built for roads to cross natural or artificial obstacles. It is erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. A bridge generally consists of a superstructure, a substructure and ancillary structures. The superstructure mainly refers to the bridge span structure and support system; the substructure includes abutments, piers and foundations; , diversion engineering, etc. According to the structural system of bridges, there are four basic systems: girder bridge, arch bridge, rigid frame bridge, and suspension cable load-bearing (suspension bridge, cable-stayed bridge). [0003] Bridge construction is the process of building a bridge according to the design content; it mainly refers to bridge construction technology, construction organization...
