In a specific embodiment, one end of the telescopic mechanism 6 is rotatably connected with the other end of the first clamping arm 2 through a first telescopic pin 61; the other end of the telescopic mechanism 6 is rotatably connected with the other end of the second clamping arm 3 through a second telescopic pin shaft 62.

In the above scheme, the other end of the first clamping arm 2 is provided with a mounting hole, one end of the telescopic mechanism 6 is provided with a through hole matched with the mounting hole, and then the first telescopic pin 61 penetrates through the mounting hole and the through hole, so that one end of the telescopic mechanism 6 can be rotatably connected with the other end of the first clamping arm 2 by using the first telescopic pin 61.

Similarly, the other end of the second clamping arm 3 is provided with a mounting hole, the other end of the telescopic mechanism 6 is provided with a through hole matched with the mounting hole, and then the second telescopic pin 62 passes through the mounting hole and the through hole, so that the other end of the telescopic mechanism 6 can be rotatably connected with the other end of the second clamping arm 3 by using the second telescopic pin 62.

According to the utility model discloses a second aspect provides a bore dress equipment, include: an apparatus main body; and the anchor rod clamping device of any embodiment of the first aspect, wherein the anchor rod clamping device is arranged on the equipment main body. Since the drill rig apparatus includes the anchor rod clamping device according to any of the embodiments of the first aspect, all the advantageous technical effects of the anchor rod clamping device are not described in detail herein.

Further, the drilling and installing device further comprises a drilling machine, wherein the drilling machine is arranged on the device body and is configured to be connected with the anchor rod to realize the drilling operation. And, because anchor rod clamping device compact structure, volume are less, and do not adopt anchor rod clamping device's drilling equipment to compare in the correlation technique, whole overall dimension increases less, nevertheless because anchor rod clamping device function pluralism has improved the convenience of drilling equipment complete machine operation greatly, is suitable for popularization and application. Further, in the overall layout, the telescopic mechanism 6 can be arranged outside the equipment, so that the telescopic mechanism 6 can be conveniently overhauled.

Specifically, bore equipment including brill installation machine, rock drill, dig anchor and protect equipment and satisfy other equipment that require, the utility model discloses do not specifically prescribe a limit to.

In the present specification, the embodiments are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same or similar parts in the embodiments are referred to each other.

The description of the present invention has been presented for purposes of illustration and description, and is not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to practitioners skilled in this art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
