Anti-falling device for bridge construction

Abstract

The invention discloses an anti-falling device for bridge construction. The device structurally comprises a net bag frame, a two-way air cylinder, a base, moving wheels, an anti-skid plate, a mountingcavity and a power device; moving wheels are installed at the bottom of the base. The mounting cavity is formed in the middle of the base, a power device is mounted in the mounting cavity; the powerdevice is communicated with the two-way air cylinders arranged on the two sides respectively; the top of the bidirectional cylinder is connected with the net bag frame; the bottoms of the bidirectional cylinders are connected with antiskid plates; the power device comprises an air inlet disc, a communicating pipe, a transmission structure and a motor. The communicating pipe is horizontally placedin the middle of the mounting cavity. The beneficial effects of the invention are that the load of the motor can be reduced under the action of the lever; extending is conducted in an intermittent airinlet mode, a traditional air inlet mode of an air inlet cylinder is avoided, the height of the power device can be reduced, the occupied area of the power device is reduced, the size of equipment isreduced, potential safety hazards caused by using a belt can be avoided in an air pressure mode, and using safety is 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
