Embodiment Construction
[0019] The following combined with the attachments, the specific implementation of the present invention further explained in detail.
[0020] Depend on Figure 1 to Figure 10 The present invention includes a hard rectangular shell 1, the upper end of the shell 1, and a rubber strip 2 on each side of the left and right end of the opening end;
[0021] There is a vertical rod 3 installed on the front and rear sides of the shell 1. The vertical rod 3 can only move up and down without swinging left and right. The center of the arc 4 is facing down. The hinge position is the left and right center position of the arc rod 4. The hinge on the front and back surface of the shell 1 has two telescopic rods 5, and the retractable rod 5 is located on the left and right sides of the vertical rod 3 and about Symmetry at about 3 vertical rods, each telescopic rod 5 or right, the other end of each retractable rod 5 is hinged with 4 hinges with the curved rod 4, and the retaining rod 5 has a pressu...

The invention relates to a protective device for water conservancy and hydropower tunnel construction. The problem that an existing dust cover cannot be suitable for sealing of tunnel side walls with different radians can be effectively solved. According to the technical scheme, the device comprises a hard rectangular shell, the upper end of the shell is open, and the left end face and the right end face of the open end are each fixedly provided with a rubber strip; the front side face and the rear side face of the shell are each provided with a vertical rod, the upper end of each vertical rod is hinged to an arc-shaped rod, the arc-shaped rods are elastic rods, the front end face and the rear end face of the shell are each hinged to two telescopic rods, the telescopic rods are located on the left side and the right side of each vertical rod and are in bilateral symmetry about the vertical rod, and the other end of each telescopic rod is hinged to the corresponding arc-shaped rod. The telescopic rod is sleeved with a pressure spring; a rubber sheet is arranged on the inner side surface of each arc-shaped rod; the device is ingenious in structure, the hard shell and the arc-shaped rod are matched, the device can be suitable for different radians of the side wall of the tunnel, the hard shell can bear large pressure, the arc-shaped rod and the side wall of the tunnel are sealed through the pressure, and dust is prevented from leaking out.
Description
Technical field [0001] The invention involves tunnel construction equipment, especially the construction protection device for water conservancy and hydropower tunnel construction. Background technique [0002] During the construction process of the tunnel, drilling is usually required to be drilled on the side wall of the tunnel. When drilling, a large amount of dust appears. When drilling below It [0003] In order to prevent the above problems, the solution at this stage is to set up a rubber layer to seal at the fitting of the dust cover and the tunnel; however, the squeezing deformation of the rubber layer can only adapt to the smaller arc change, and the side wall of the tunnel wall can be adapted. The arc arc is inconsistent. When the side wall of the tunnel changes large, the rubber layer cannot be completely sealed, which will cause the dust to overflow from the gap. Invention content [0004] In response to the above problems, in order to solve the problems existing in...
