Abstract

The invention discloses an anti-falling device for bridge construction, the structure of which comprises a net rack, a two-way cylinder, a base, a moving wheel, an anti-skid plate, a mounting cavity, and a power device. A power device is installed in the cavity, and the power device is respectively connected with the two-way cylinders on both sides. The top of the two-way cylinder is connected with the net rack, and the bottom of the two-way cylinder is connected with the anti-skid plate. The power device includes an air intake plate, a connecting pipe, and a transmission structure. , the motor, and the connecting pipe is placed horizontally in the middle of the installation cavity. The beneficial effects of the present invention are: the load of the motor can be reduced through the action of the lever, and the elongation is carried out by means of intermittent air intake, avoiding the traditional air intake method of the air intake cylinder, The height of the power device can be reduced, the floor area of ​​the power device can be reduced, and the size of the equipment can be reduced. The safety hazard of using the belt can be avoided by means of air pressure, and the safety of use can be improved.

Description
