Highway construction cross-line construction safety protection device

Abstract

A highway construction cross-line construction safety protection device comprises a movable base (1), a top plate (6) used for blocking falling objects above the movable base (1) is arranged above themovable base (1), a lifting assembly used for lifting the top plate (6) is arranged between the movable base (1) and the top plate (6), and two symmetrical extending plates (8) are horizontally and slidably connected to the left side and the right side of the upper portion of the top plate (6), and the bottom of each extending plate (8) is fixedly connected with a length-adjustable telescopic sleeve rod (9). The top plate and the extending plates are arranged on the movable base; after the top plate is adjusted to the proper height through the lifting assembly, the two telescopic sleeve rodsare pushed to slide the two extending plates out of the two sides of the top plate, and the top plate and the extending plates can form a baffle for preventing objects falling from high altitudes; when an object on a constructed overpass bridge falls down to a road, the object can directly hit the top plate and the extending plates, and damage to vehicles on the road is avoided.

Description

technical field [0001] The invention relates to the technical field of over-line bridge construction, in particular to a safety protection device for over-line construction in highway construction. Background technique [0002] The flyover is an upper-span facility across the road. It is usually set up at places where pedestrians, bicycles and other vehicles cross expressways and first-class roads, especially where traffic flow conflicts are serious, such as stations, large commercial centers or other intersections. Over-the-line (overpass) bridge refers to a bridge that crosses traffic lines such as highways, railways or urban roads. Cross over existing lines. Divided into separate and interoperable. The former only ensures that the vehicles on the upper and lower lines can pass independently; the latter allows the vehicles on the upper and lower lines to pass through each other, and builds complex roundabout ramps on the plane and elevation, occupying a lot of land.

AI Technical Summary

Problems solved by technology

[0003] At present, during the construction of the overpass bridge, since the construction location is above the road, falling objects may fall directly on the road during construction, and the bridge body is not formed in the initial stage of construction, so it is impossible to completely build a high-altitude fall prevention network, which brings hidden dangers to construction safety, so it is necessary to design a safety protection device for cross-line construction of highway construction to solve this problem
