Abstract

The invention discloses a lighting device for tunnel construction with good protection effect, comprising a box body, two first telescopic rods are 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 sliding plate . The present invention uses a first telescopic rod, a sliding plate, a first spring, a sliding block, a sliding rod, a limit block, a second spring, a fixing plate, a dustproof plate, a first chute, a first sliding block, and a second chute , the second slider, the second telescopic rod, the return spring, the fixed seat, the support rod, the fixed groove, the extrusion block, the third chute, the third slider and the third spring cooperate with each other to solve the common tunnel construction problems. The protection effect of the lighting device is not ideal. During the construction of the tunnel, it plays a role of shock absorption for the gravel and prevents the lighting device from being smashed. Construction brings great convenience.

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...
