An anti-drop device for bridge construction

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

technical field [0001] The invention relates to the field of bridge construction, in particular to an anti-drop device for bridge construction. Background technique [0002] Bridge construction is the process of building a bridge according to the design content; it mainly refers to bridge construction technology and construction organization, construction management, construction quality, etc. During the bridge construction process, safety measures are very important, and bridge construction anti-drop devices are required. [0003] The existing patent No. 201910087979.3 is a bridge construction anti-dropping device, which includes an installation box; a first partition is fixed inside the installation box; a transmission motor is installed on the upper side of the first partition; the left and right sides of the transmission motor There are connecting shafts on both sides; a second limit slider is slidably connected in the cavity at the lower part of the connecting shaft; a ...

[0003] The existing patent No. 201910087979.3 is a bridge construction anti-dropping device, which includes an installation box; a first partition is fixed inside the installation box; a transmission motor is installed on the upper side of the first partition; the left and right sides of the transmission motor There are connecting shafts on both sides; a second limit slider is slidably connected in the cavity at the lower part of the connecting shaft; a second movable rod is fixed on the lower side of the second limit slider; the lower side of the second movable rod An anti-movement plate is fixed; a first limit slider is slidably connected in the cavity on the upper part of the connecting shaft; a first movable rod is fixed on the upper side of the first limit slider; a lifting lever is fixed on the upper side of the first movable rod. plate; the first fixed block is fixed on the upper side of the lifting plate; the first guide slide bar is fixed between the first fixed blocks; the present invention has reasonable structural design and is easy to use. When adjusting the height of the device, it can simultaneously Drive the anti-movement plate to support the device to prevent the device from moving. The device has high stability and good anti-drop effect, which has strong practicability. However, this technology uses a belt drive to drive the lifting. Because the equipment is heavy, the belt and The load of the motor, the belt is easy to pull and wear, and in severe cases, it will break under the working condition, which has potential safety hazards
