Embodiment 1

[0024] see Figure 1~2 , in the embodiment of the present invention, a kind of anti-falling device that urban bridge construction is used, comprises frame, protective net 10 and corrugated rubber air bag 3, and described frame comprises two supporting boards 1 that are arranged symmetrically, two supporting boards 1 The bottom is welded and fixed with a fixed plate 16, and the bottom of the fixed plate 16 is equipped with a roller 17. The roller 17 is a self-locking roller to facilitate the movement of the device. The fixed plate 16 is pierced with a plurality of drill rods 15, The drill pipe 15 is threadedly connected with the fixed plate 16, and the top of the drill pipe 15 is integrally provided with a turning handle, and the drill pipe 15 can be drilled into the ground by rotating the drill pipe 15 through the turning handle, thereby keeping the device stable. Both are equipped with a mounting plate 4. In this embodiment, the mounting plate 4 is preferably fixed to the sup...

Embodiment 2

[0026] see image 3 The difference between this embodiment of the present invention and Embodiment 1 is that further, in order to be able to adjust the height of the protective net 10, a second motor 21 is installed on the top of the support plate 1, and the output shaft of the second motor 21 is fixedly installed There is a threaded rod 20, the top of the threaded rod 20 extends into the mounting plate 4 and is threadedly connected with the mounting plate 4, the top of the support plate 1 is fixed with a plurality of guide rods 22 for guiding the motion of the mounting plate 4, the guide rods 22 Preferably be fixed with the mounting plate 4 by welding, the mounting plate 4 is provided with a guide groove for the guide rod 22 to penetrate, by starting the second motor 21, the second motor 21 drives the threaded rod 20 to rotate, and the threaded rod 20 drives the mounting plate 4 to carry out Lifting, so as to be able to adjust the protective height of the protective net 10, t...

Abstract

The invention discloses an anti-falling device for urban bridge construction. The anti-falling device for urban bridge construction comprises a machine frame, protective nets and a corrugated rubber air bag, wherein the machine frame comprises two symmetrically arranged supporting plates, the corrugated rubber air bag is connected between the two supporting plates, multiple sets of electric scissors fork mechanisms are connected between the front ends and the rear ends of the two supporting plates, the multiple protective nets are installed between two mounting plates from top to bottom, two-way screw rods are rotatably installed on opposite surfaces of the two mounting plates, a fixed mounting column is arranged in the middle of each two-way screw rod, and thread sections on two sides ofeach two-way screw rod are in threaded connection with movable mounting columns. The electric scissors fork mechanisms are arranged, the distance between the two supporting plates can be adjusted through the electric scissors fork mechanisms, the protective area of the whole protection device is adjusted, adaptability is higher, and a better anti-falling effect is achieved. The two-way screw rods,the fixed mounting columns, the movable mounting columns and winding rollers are arranged, so the distance between the adjacent protective nets can be adjusted, and the tensioning degree of the protective nets can be adjusted.

Description

technical field [0001] The invention relates to the technical field of urban bridge construction protection, in particular to a fall prevention device for urban bridge construction. Background technique [0002] Urban bridges refer to bridges built on rivers, roads and road overpasses, overpasses and pedestrian bridges where roads cross railways within the city. Including permanent bridges and semi-permanent bridges, excluding temporary bridges, railway bridges, and culverts. [0003] The anti-falling device is suitable for high-rise building construction, shipbuilding, ship repairing, water loading and unloading, large-scale equipment installation and other high-altitude and working places to prevent people and objects from falling or to avoid and reduce the injury of falling objects. Existing anti-falling devices are generally fixed frame structures, and its size cannot be adjusted, so that the protection area cannot be adjusted, and it cannot adapt to different construct...
