Abstract

The invention discloses a tunnel construction lighting device good in protecting effect. The tunnel construction lighting device comprises a box and is characterized in that two first telescopic rodsare fixedly connected to the bottom of the inner wall of the box, and the tops of the two first telescopic rods are fixedly connected through a slide plate. The tunnel construction lighting device hasthe advantages that by the coordination of the first telescopic rods, the slide plate, first springs, sliders, slide rods, limit blocks, second springs, a fixing plate, dustproof plates, first slidegrooves, first sliders, second slide grooves, second sliders, second telescopic rods, reset springs, fixing seats, support rods, fixing grooves, squeezing blocks, third slide grooves, third sliders and third springs, the problem that a common tunnel construction lighting device is unsatisfactory in protecting effect is solved, a gravel damping effect is achieved during tunnel construction, the lighting device is prevented from being smashed, the service life of the lighting device is prolonged, potential safety hazards are avoided, and great convenience is brought to tunnel construction.

Description

technical field [0001] The invention relates to the technical field of tunnels, in particular to a lighting device for tunnel construction with good protection effect. Background technique [0002] A tunnel is a building built underground or underwater or in a mountain, laying a railway or building a road for the passage of motor vehicles. According to its location, it can be divided into three categories: mountain tunnels, underwater tunnels and urban tunnels. In order to shorten the distance and avoid large ramps, it is called a mountain tunnel that passes under mountains or hills. In order to cross rivers or straits, it is called an underwater tunnel that passes under a river or under the sea. Those that pass underground are called urban tunnels. Among the three types of tunnels, mountain tunnels are the most built. The light in the tunnel is dim, and the construction workers need lighting devices to carry out tunnel construction. The protection effect of common lightin...
