AI Technical Summary
When the existing anchor machine is constructed to protect the anchor eye, the anchor machine legs can only be supported on the bottom plate, resulting in the anchor eye not being perpendicular and unable to meet the quality requirements. At the same time, when the lowest row of anchor eye is punched, the anchor machine is almost parallel to the ground, and the anchor machine legs are difficult to support, which poses safety hazards.
A coal mine underground multi-angle anchor machine frame is designed, including brackets, drilling rig bases, angle adjustment blocks and combined telescopic beams. Through the combination and adjustment of these components, multi-angle support and stable drilling are achieved.
The frame structure is stable and has high safety performance, which reduces safety risks during drilling of anchor machines, improves drilling efficiency and accuracy, and saves two-thirds of the time when hitting a negative angle.

[0005] Preferably, a plurality of first mounting holes for mounting the drilling machine seat are uniformly arranged on the bracket from bottom to top at intervals.
[0006] Preferably, a plurality of second mounting holes for cooperating with the upper end of the bracket are uniformly arranged on the angle adjustment block at intervals.
[0007] Preferably, the combined telescopic beam and the bracket are connected by a spherical hinge.

[0009] Preferably, the combined telescopic beam includes an outer cylinder and an inner rod, a plurality of threaded holes are uniformly arranged on the outer cylinder, the threaded holes are used for installing fastening bolts, and the fastening bolts limit the inner rod relative to the outer cylinder.
[0010] Preferably, a fixing ring for fixing the bracket on the ground is fixed to the outer periphery of the lower end of the bracket.
[0011] Advantages of the present utility model: Compared with the prior art, the present utility model can be disassembled and assembled, which is convenient for transportation and installation. The multi-angle bolt drill rig frame has a stable structure and high safety performance, reducing potential safety hazards during drilling of the bolt drill rig, effectively improving the drilling efficiency, especially saving two-thirds of the time when drilling at a negative angle. Since the angle of the drill rig is adjustable, the drilling accuracy and quality are improved. Description of the Drawings
[0012] Figure 1 It is a schematic diagram of the overall structure of the present utility model.
[0013] Figure 2 It is a schematic diagram of the combined telescopic beam structure.
[0014] The reference numerals in the drawings of the specification include: support 1, drill rig base 2, angle adjustment block 3, combined telescopic beam 4, outer cylinder 41, inner rod 42, threaded hole 43, fixing ring 5, mounting block 6. Specific Embodiments
[0015] The present utility model will be further introduced below in conjunction with the drawings and specific embodiments.
[0016] Embodiment 1:
[0017] A multi-angle bolt drill rig frame for underground coal mines, as Figure 1 shown, includes a support 1. A fixing ring 5 for fixing the support 1 to the ground is fixedly arranged on the outer periphery of the lower end of the support 1. The lower end of the support 1 is fixed on the roadway ground to ensure that the frame of the bolt drill rig does not shake during drilling, thereby ensuring the personal safety of the staff. The upper end of the support 1 is arranged obliquely towards the upper right. A drill rig base 2 is connected to the support 1 by bolts. The left end of the drill rig base 2 is connected to the support 1, and an angle adjustment block 3 is hinged to the right end of the drill rig base 2. The upper part of the angle adjustment block 3 is connected to the upper end of the support 1 by bolts. The support 1, the drill rig base 2, and the angle adjustment block 3 form a stable triangle to ensure the stability during drilling. A plurality of first mounting holes for mounting the drill rig base 2 are evenly arranged on the support 1 from bottom to top, facilitating the adjustment of the height of the drill rig base 2. A plurality of second mounting holes for cooperating with the upper end of the support 1 are evenly arranged on the angle adjustment block 3, facilitating the adjustment of the inclination angle of the drill rig base 2. The upper end of the support 1 is connected to a combined telescopic beam 4 by a ball joint. The left end of the combined telescopic beam 4 is hinged to the support 1, and a mounting block 6 arranged vertically and cooperating with the bolt is fixed to the right end of the combined telescopic beam 4. The right end of the combined telescopic beam 4 is fixed to the bolt on the roadway sidewall through the mounting block 6. Connecting the upper end of the support 1 to the combined telescopic beam 4 by a ball joint facilitates the arbitrary adjustment of the combined telescopic beam 4 in the up, down, left, and right directions to cooperate with different bolts.
[0018] In this embodiment, as Figure 2As shown, the combined telescopic beam 4 includes an outer cylinder 41 and an inner rod 42. A plurality of threaded holes 43 for installing fastening bolts are evenly spaced on the outer cylinder 41. The inner rod 42 is limited relative to the outer cylinder 41 by the fastening bolts. When the direction and angle of the combined telescopic beam 4 change, the length of the combined telescopic beam 4 must change accordingly to always meet the requirements.

Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claimed rights.
