Shockproof protection frame for tunnel engineering

Abstract

The invention discloses a shockproof protection frame for tunnel engineering, which comprises a placing plate and a top plate, one side of the outer side face of the placing plate is fixedly connected with a polished rod and a placing groove, a transmission structure is arranged in the placing groove, and the transmission structure comprises a first-stage electric telescopic rod, a rack, a first-stage gear, a short rod and an oval block. A sliding plate is slidably connected to the outer side face of the polished rod, and a lifting structure is arranged on one side of the upper portion of the sliding plate. According to the quakeproof protection frame for tunnel engineering, through cooperative arrangement of the damping structures, the quakeproof protection frame for tunnel engineering has the effect that the quakeproof protection frame for tunnel engineering is not prone to inclining, so that the effect of improving the stability performance is achieved, and the purpose of improving the quakeproof effect is achieved; through matched setting of the transmission structure and the lifting structure, in the using process, the indirect direction and the height of the shockproof protection frame for the tunnel engineering can be adjusted, so that the effects of convenience and rapidness are achieved, and the purpose of convenient adjustment is achieved.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering, in particular to an anti-shock protective frame for tunnel engineering. Background technique [0002] The structure of the tunnel includes two parts, the main building and the auxiliary equipment. The main building is composed of the tunnel body and the tunnel door, and the auxiliary equipment includes car avoidance tunnels, fire-fighting facilities, emergency communication and waterproof and drainage facilities, and the long tunnel also has special ventilation and lighting equipment. [0003] During the blasting construction of the tunnel, the tunnel needs to be erected. At present, the existing erection is poor in shock resistance and often tilts to prevent the tunnel from blasting. The board may fall during the construction of the workers, causing injury to the workers or damage to the protective frame. In addition, the vertical frame is not convenient for subsequent adjustment aft...
