Problems solved by technology
However, in the actual construction process on site, the anchor bolt holes are all manually drilled by a hand-held bolter, which has the disadvantages of difficult positioning and fixing. The bolter has only one leg supported on the trolley, which is easy to cause the bolt The positioning and angle do not meet the design requirements, and the bolt and surrounding rock cannot form a stable force-bearing system, and there are large quality risks

Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings.
[0020] Such as Figure 1 to Figure 8 As shown, the adjustable rock bolt bracket includes a universal adjustment support 1, a telescopic support leg 2 and a quick fixing buckle 3.
[0021] The universal adjustment support 1 is composed of a drilling rig bracket 4, a rotating shaft 5, a fixed disk 6, a rotating disk 7 and a ball bearing 8, and the rotating disk 7 is mounted on the fixed disk 6 through the ball bearing 8. The drilling rig bracket 4 is hingedly connected to the rotary disc 7 through the rotary shaft 5, so that the drilling rig bracket can adjust the pitch angle within ±50° around the rotary shaft, and the rotary disc 7 drives the drilling rig bracket Frame 4 can be rotated and adjusted 360° in the horizontal plane (such as Image 6 shown).
[0022] The number of the outriggers 2 is three groups, wherein two groups of outriggers 2 are arranged horizontal...

The invention discloses an adjustable-type anchor rod drilling machine support. The adjustable-type anchor rod drilling machine support comprises a drilling machine bracket, a fixing disk and at leasttwo sets of supporting legs. The drilling machine bracket is installed on the fixing disk. The upper end of each set of the supporting leg is connected with the fixing disk through a hinge, and the lower end of each set of the supporting leg is provided with a rapid fixing buckle. The rapid fixing buckles are composed of connecting rods, upper retaining rings, lower retaining rings and movable lock catches. The upper ends of the connecting rods are connected with the lower ends of the corresponding supporting legs, and the lower ends of the connecting rods are connected with the upper retaining rings. One ends of the upper retaining rings are connected with one ends of the corresponding lower retaining rings through rotating shaft hinges, and the other ends of the upper retaining rings and the other ends of the lower retaining rings are fixed through the movable lock catches. The adjustable-type anchor rod drilling machine support in the design can be widely applied to drilling and installation of various kinds of tunnel system anchor rods, and the adjustable-type anchor rod drilling machine support has the advantages of being simple in structure, easy to operate, durable in use,flexible to move, high in adjusting precision, capable of saving labor and energy, high in efficiency and the like.
Description
technical field [0001] The invention relates to a tunnel initial support construction device, in particular to an adjustable bolter rig support. Background technique [0002] At present, there are strict spacing and angle requirements for the setting of the initial support bolts of the tunnel according to the design. The anchor shotcrete support is the core stress system of the new Austrian method tunnel. The bolt is an important factor to strengthen the surrounding rock structure and control the deformation of the surrounding rock. And stress release, so that in the joint deformation process of support and surrounding rock, adjust the stress redistribution of surrounding rock to achieve a new balance, so as to stabilize the surrounding rock. However, in the actual construction process on site, the anchor bolt holes are all drilled manually with a hand-held bolter, which has the disadvantages of difficult positioning and fixing. The bolter has only one leg supported on the t...
