Description

Technical Field

[0001] This utility model relates to the technical field of anchor drilling machine positioning devices, and more specifically, to a pneumatic outrigger type positioning device for anchor drilling machines. Background Technology

[0002] Pneumatic outrigger-type anchor bolt drilling rigs are widely used in underground engineering for drilling operations on tunnel roofs and sidewalls. This equipment uses pneumatic legs to support the ground for lifting and lowering, enabling drilling of anchor bolt holes in the tunnel roof to ensure the stability of the surrounding rock. Its outrigger design allows for flexible height and angle adjustment, ensuring accurate drilling positioning. However, the rig's support and fixation rely entirely on manual operation. Once the rig is running, the pneumatic legs are prone to loosening or displacement due to vibration or geological pressure, leading to insufficient rig stability. During operation, drilling is prone to deviation, making it difficult to guarantee the verticality of the hole, directly affecting the anchor bolt installation effect and project safety. Furthermore, this drilling method accelerates drill bit wear, reduces operational efficiency, and increases costs. Utility Model Content

[0003] To overcome the above deficiencies, this utility model provides a positioning device for a pneumatic outrigger type anchor bolt drilling rig, which solves the above problems.

[0004] This utility model is implemented as follows:

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] like Figure 1-4 As shown, this utility model provides a positioning device for a pneumatic outrigger type anchor bolt drilling rig, including a base 1. The base 1 includes a main frame 11. Outriggers 12 are provided at the four corners of the bottom of the main frame 11. A mounting plate 13 is provided near the middle of the top of the main frame 11. A drilling rig fixing frame 2 is provided on the mounting plate 13. The drilling rig fixing frame 2 includes a mounting seat 21 fixedly mounted on the mounting plate 13. A channel steel column 22 is hinged to the mounting seat 21. A load-bearing plate 23 is provided on the front side of the bottom of the channel steel column 22. A top of the load-bearing plate 23 is provided with... The air leg mounting base 24 and the channel steel column 22 are equipped with a drilling rig guide assembly 3 on the front side. The rear side of the channel steel column 22 and the mounting plate 13 are equipped with an inclination adjustment assembly 4. The inclination adjustment assembly 4 is used to adjust the angle between the channel steel column 22 and the main frame 11. In use, the air leg of the drilling rig is fixed on the drilling rig mounting frame 2, and the drill bit above it is fixed on the drilling rig guide assembly 3. Then, based on the actual measured drilling orientation, the placement position of the base 1 is adjusted, and the inclination adjustment assembly 4 is adjusted so that the drilling direction of the drilling rig remains stable and points in one direction.

[0025] In this embodiment, two channel steels parallel to the main frame 11 are provided on the front side of the top of the mounting base 21. A shaft hole is opened on the front side of the opposite side of the two channel steels. The left and right sides of the channel steel column 22 are hinged to the shaft hole on the two channel steels through the shaft rod.

[0026] In this embodiment, the left and right sides of the load-bearing plate 23 have upwardly extending first wing plates, and the sides of the first wing plates have elongated holes. The left and right sides of the air leg fixing seat 24 have downwardly extending second wing plates, and the second wing plates are fixed to the elongated holes on the adjacent side by bolts. The top center of the air leg fixing seat 24 has a placement groove 242, and the rear side of the top of the air leg fixing seat 24 has a vertical plate 241. The front side of the vertical plate 241 has a first pipe clamp 243. In use, after the air leg bracket of the drilling rig passes through the placement groove 242 and contacts the load-bearing plate 23, it is fixed by the first pipe clamp 243. The design of the elongated holes on the load-bearing plate 23 facilitates the fine adjustment of the front and rear position of the air leg fixing seat 24. The purpose is to adapt to different sizes of the pneumatic outrigger 12-type anchor bolt drilling rig, adjust the front and rear distance of the air leg, and keep the air leg and drill rod parallel to the channel steel column 22 when fixing the drill bit part later.

[0027] In this embodiment, the drilling rig guide assembly 3 includes a slide 31 fixedly installed on the front side of the channel steel column 22. Two slide rods 32 are provided on the front side of the slide 31. A slide seat 33 is slidably installed on the slide rods 32. A second pipe clamp 34 is provided on the front side of the slide seat 33. The second pipe clamp 34 is used to fix the drill bit of the drilling rig. When the air leg provides the lifting action, the drill bit is kept moving in the same drilling direction by the action of the drilling rig guide assembly 3, so as to ensure the stability of the drilling operation.

[0028] In this embodiment, the tilt adjustment assembly 4 includes a support rod 41 and a tilt adjustment plate 44. The tilt adjustment plate 44 is disposed on the top of the main frame 11 and is located on the rear side of the top of the main frame 11. A second hinge seat 43 is slidably disposed on the tilt adjustment plate 44. A first hinge seat 42 is fixedly disposed on the rear side of the channel steel column 22 near the top. The two ends of the support rod 41 are respectively hinged to the two hinge seats.

[0029] Furthermore, the top of the tilt adjustment plate 44 is provided with a sliding groove, and the bottom sides of the second hinge seat 43 are provided with protrusions that fit into the sliding groove.

[0030] Furthermore, a lead screw 45 is provided at the center of the chute, and guide rods 46 are provided on both sides of the lead screw 45. The rear end of the lead screw 45 passes through the tilt adjustment plate 44, and a handle 47 is provided at the end. The lead screw 45 is threadedly connected to the first hinge seat 42, and the guide rod 46 is slidably connected to the second hinge seat 43. By adjusting the handle 47, the angle of the channel steel column 22 can be further adjusted. In its application scenarios, this device can be used to assist in the positioning of this model of anchor drilling machine for curved domes.

[0031] It should be noted that the lead screw 45 is a trapezoidal lead screw 45, and the connection between it and the second hinge seat 43 is a trapezoidal lead screw 45 slider structure. The advantage of this structure is that it has a self-locking function, that is, when the lead screw 45 is not actively rotated, the support rod 41 will not be subjected to indirect force on the lead screw 45 due to the pressure of the channel steel column 22, causing it to move and thus produce an angular deviation.

[0032] Specifically, the working principle of the positioning device for a pneumatic outrigger type anchor bolt drilling rig is as follows: During use, the air leg of the drilling rig is fixed in the air leg fixing seat 24 of the load-bearing plate 23, and then the drill bit is fixed on the slide seat 33 of the drilling rig guide assembly 3 through the second pipe clamp 34. During this process, the position can be adjusted by the bolts on both sides of the air leg fixing seat 24 so that the entire drilling rig is parallel to the channel steel column 22. The tilt angle adjustment assembly 4 drives the second hinge seat 43 to move along the slide groove through the screw 45, thereby driving the support rod 41 to adjust the angle of the channel steel column 22 to adapt to the needs of complex curved surfaces such as domes. The trapezoidal screw 45 has a self-locking function to prevent angle deviation. Through the above structure, the problems of existing drilling rigs lacking fixing devices, poor machine stability, poor hole quality, and accelerated drill bit wear after the drilling rig starts running are solved.

[0033] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
