[0029] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] The invention discloses a telescopic and rotatable deep hole drilling machine adjustment mechanism for coal mining working face, such as Figure 1 As shown, it includes a fixed plate 10 fixedly connected to the bottom of the deep hole drill, a connecting mechanism 30 is connected to the bottom of the fixed plate 10 through a vertical angle adjustment mechanism 20, a clamping mechanism 50 is connected to the bottom of the connecting mechanism 30, and the connecting mechanism 30 can rotate horizontally relative to the clamping mechanism 50; the clamping mechanism 50 is used to be detachably connected to the support member below; the vertical angle adjustment mechanism 20 includes a sleeve 22, the sleeve 22 is fixed to the bottom surface of the fixed plate 10, and the axis of the sleeve 22 is parallel to the drilling direction of the deep hole drill, and a rotating shaft 21 is passed through the sleeve 22, and the rotating shaft 21 can rotate in the vertical direction relative to the sleeve 22; wherein, through the vertical angle adjustment mechanism 20 and the connecting mechanism 30, the angle adjustment of the deep hole drill in the vertical direction and the horizontal direction can be realized.

[0031] The present invention adds a vertical angle adjustment mechanism and a connecting mechanism between the deep hole drill and the support respectively, thereby realizing the angle adjustment of the deep hole drill in the vertical direction and the horizontal direction when drilling, so as to facilitate the use of the deep hole drill to construct holes with inclined angles and reduce the difficulty of operation.

[0032] As another implementation, a bearing may be installed between the rotating shaft 21 and the shaft sleeve 22, which may be more convenient and more labor-saving to operate.

[0033] In this embodiment, the connection mechanism 30 includes an upper connection plate 31 fixedly connected to the rotating shaft 21, and a lower connection plate 32 is fixedly connected below the upper connection plate 31. A bearing 34 is installed on the lower connection plate 32, and the axis of the bearing 34 is perpendicular to the axis of the sleeve 22. In this way, the upper and lower parts of the adjustment mechanism are rotatably connected through the bearing 34, which can save more effort during construction and facilitate operation.

[0034] In another embodiment, the connecting mechanism 30 and the clamping mechanism 50 are connected by the lifting mechanism 40, and the connecting mechanism 30 can rotate horizontally relative to the lifting mechanism 40. Through the lifting mechanism 40, the construction height of the deep hole drilling machine can be adjusted according to the construction height of the drilling hole, increasing the adaptability of the adjustment device.

[0035] Specifically, Figure 2As shown, both sides of the rotating shaft 21 are fixedly connected to the upper connecting plate 31 through the connecting blocks 23. The shape of the connecting block 23 can be selected as needed, such as a square block, a bar block, etc., and the connecting blocks 31 are two, which are located on both sides of the shaft sleeve 22.

[0036] In order to increase the convenience of the adjustment mechanism, the upper connecting plate 31 and the lower connecting plate 32 are connected by connecting bolts 33. When it is necessary to replace accessories or store them, they can be disassembled into multiple parts.

[0037] In one embodiment, the bottom surface of the lower connecting plate 32 extends upward with a mounting hole, and a bearing 34 is mounted in the mounting hole.

After the connecting plate is inserted between the two clamping plates 52, it is tightened by the clamping bolt 53.

[0040] More specifically, in order to prevent the splint 52 from deforming after long-term use, a reinforcing piece is further provided on the outer side of the splint 52. The reinforcing piece is welded to the outer side of the splint 52 to play a supporting and reinforcing role.
