Problems solved by technology

However, due to the construction method, the large-scale tunnel construction machinery is limited by the working space, and it is impossible to use the three-arm rock drilling rig for drilling, and can only rely on the manual air gun for drilling. The traditional manual air gun drilling angle control is basically Relying on manual experience, or welding a guide tube on the side of the arch, the human error is relatively large, and it cannot accurately control the drilling angle

Embodiment Construction

[0018] figure 1 , figure 2 and image 3 It is a schematic schematic diagram and a schematic structural diagram of a device for drilling angle control according to an embodiment of the present invention.

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. The present invention includes a tripod 1, an angle adjuster 6; the angle adjuster 6 includes an angle plate 2, an angle rod 3, a positioning ring 4, a positioning rod 5, and a leveling plate 7;

[0020] The method of use of the present invention is as follows: when the air gun needs to be set up manually due to the limitation of the construction work space, the tripod 1 and the angle adjuster 6 are connected through the connection The bolts 10 are connected and the leveling disc 7 below the angle adjuster 6 is adjusted. When the air bubble is at the center of the leveling disc 7, the height of the legs of the tripod 1 is fixed by ...

Abstract

The invention discloses a device used for controlling an angle of hole drilling. The device comprises a triangle supporting frame and an angle adjustor; the angle adjustor comprises an angle scale, anangle rod, locating rings, locating rods and a leveling disc. All the locating rods are vertically placed, the bottom parts of the locating rods are installed on a horizontal rod, and the angle scaleis installed on the end part of the horizontal rod; the horizontal rod is vertically connected with the leveling disc; the top part of the triangle supporting frame is connected with the leveling disc arranged on the bottom part of the angle adjustor by connecting bolts, and an angle of the angle adjustor, that is the angle between the angle rod and the horizontal rod, is adjusted; inner diameters of the locating rings are larger than external diameters of drilling pipes, therefore normal operation of the drilling pipes is guaranteed, and the angle of hole drilling is controlled. Compared with traditional tunnel manual blower gun drilling construction, the device used for controlling the angle of hole drilling can make angle control of hole drilling more accurate.

Description

technical field [0001] The invention relates to the related technical field of tunnel construction technology, in particular to a trolley for installation and removal of wind and water pipes. Background technique [0002] Tunnel advanced small conduit is a very effective auxiliary construction method for stabilizing the excavation face. In the construction of weak and broken rock formations, the advanced small conduits can reinforce the loose rock formations. After grouting, the stability of loose and weak surrounding rocks is enhanced, which is beneficial to the stability of the surrounding rocks after the completion of excavation and the completion of initial support. , so that the surrounding rock will not be unstable and damaged until it collapses. Lock foot bolt passes through weak, loose and unstable rock and soil mass, and is anchored on the deepest and most stable rock and soil mass to provide sufficient pulling force to overcome the self-weight and sliding force of...
