Technical Field

[0001] This utility model relates to the field of adjustment structure technology, specifically a spacing adjustment structure for coal bunker drilling equipment. Background Technology

[0002] Drilling anchor bolts inside coal bunkers is time-consuming and inconvenient due to manual adjustments, especially in circular coal bunkers where space is limited, leading to a significant reduction in efficiency.

[0003] To address the aforementioned technical issues, existing structures can be adjusted, including in terms of rotation, height, and angle. This approach does indeed improve the efficiency of anchor drilling within a circular coal bunker, as it is not limited by space constraints. However, this structure still presents certain technical challenges. During operation, especially during drilling, the reverse force generated by the drilling rig can cause the structure to tilt in the opposite direction, thus affecting the drilling quality.

[0004] In order to solve the above-mentioned technical problems and prevent the structure from tilting due to the reverse force when the drilling rig moves, thus affecting the drilling quality, the technical problems in the prior art can be overcome. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a spacing adjustment structure for coal bunker drilling equipment, which solves the problem that existing structures for adjusting coal bunker anchor bolt drilling tend to tilt due to reaction forces when the drilling rig moves during drilling.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a spacing adjustment structure for a coal bunker drilling equipment, comprising a rotating base structure and an adjustment structure. The adjustment structure is mounted on the rotating base structure, and a movable structure is mounted on the side of the adjustment structure. An anchor drilling rig is mounted on the movable structure. The movable structure includes a movable frame, hydraulic cylinders, guide plates, a second support plate, a motor, a threaded shaft, a movable plate, and a first support plate. The movable frame is mounted on the adjustment structure. Hydraulic cylinders are mounted on the top and bottom of the inner side of the movable frame. The two sets of hydraulic cylinders face opposite directions. A guide plate is mounted on the telescopic end of one set of hydraulic cylinders, and the guide plate has an opening on its surface. A second support plate is mounted on the telescopic end of the other set of hydraulic cylinders. A motor is mounted on the upper end of the movable frame, and guide rails are symmetrically mounted. A slider moves on the guide rails, and a movable plate is connected to the slider. A first support plate is mounted on the upper end of the movable plate. The anchor drilling rig is mounted on the upper surface of the first support plate. A bearing seat is also mounted on the upper end of the movable frame. A threaded shaft is connected to the output end of the motor. The end of the threaded shaft is connected to the inner ring of the bearing seat. The threaded shaft and the movable plate form a threaded connection.

[0007] Furthermore, the upper end of the mobile frame is also equipped with a second support wheel, which contacts the lower end face of the first support plate.

[0008] Furthermore, the two sets of hydraulic cylinders are equidistant from the ports of the corresponding moving frame, and plates with openings are installed on both ends of the moving frame, through which the telescopic ends of the hydraulic cylinders pass.

[0009] As a preferred technical solution, the rotating base structure includes a chassis, an internal housing, a geared motor, a bearing housing, gears, transmission gears, a turntable, and a rotating disk;

[0010] The chassis end face has an opening, and an inner box is installed on the inner top surface of the chassis. A bearing seat is installed on the inner side of the inner box, and a gear motor is installed on the lower end face of the inner box. The output end of the gear motor is connected to a shaft, the surface of which is connected to the inner ring of the bearing seat, and a gear is installed at the end. A turntable is installed on the upper end of the chassis, and a transmission gear is installed on the lower end face of the turntable. The transmission gear meshes with the gear for transmission. A rotating disc is installed on the upper end of the turntable.

[0011] Furthermore, the upper surface of the chassis is provided with a ring-shaped array of support wheels.

[0012] As a preferred technical solution, the adjustment structure includes a mounting base, a second geared motor, a guide rail, a movable seat, a first threaded shaft, and a rotating base. The mounting base is installed on the upper surface of the chassis. The second geared motor is installed on the upper surface of the mounting base. The output end of the second geared motor is connected to the first threaded shaft. Guide rails are symmetrically installed on the inner side of the mounting base. A slider moves on the guide rail. A movable seat is connected to the slider. A rotating base is installed on the outer side of the movable seat.

[0013] Compared with the prior art, this utility model provides a spacing adjustment structure for coal bunker drilling equipment, which has the following beneficial effects:

[0014] 1. This structure uses two sets of hydraulic cylinders within the movable frame, arranged in opposite directions. During drilling, both sets of hydraulic cylinders are activated simultaneously, causing the guide plate and support plate to extend and contact the coal bunker surface, thereby generating relative force between the two sets of hydraulic cylinders. Furthermore, when the anchor bolt drilling rig moves and drills, the openings on the guide plate facilitate position guidance. Therefore, based on the above, the problem of structural tilting caused by the reaction force during drilling when adjusting the existing structure for anchor bolt drilling in coal bunkers is solved.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0023] Please see Figure 1-6This utility model provides the following technical solution: a spacing adjustment structure for a coal bunker drilling equipment, comprising a rotating base structure 1 and an adjustment structure 2, wherein the adjustment structure 2 is mounted on the rotating base structure 1. The characteristic feature is that a movable structure 3 is mounted on the side of the adjustment structure 2, and an anchor drilling rig 4 is mounted on the movable structure 3. The movable structure 3 includes a movable frame 301, a hydraulic cylinder 302, a guide plate 303, a second support plate 304, a motor 305, a threaded shaft 306, a movable plate 307, and a first support plate 308. The movable frame 301 is mounted on the adjustment structure 2, and hydraulic cylinders 302 are mounted on the top and bottom of the inner side of the movable frame 301, with the two sets of hydraulic cylinders 302 facing opposite directions. One set of hydraulic cylinders 302 has a guide plate 303 installed at the telescopic end, and the guide plate 303 has an opening on its surface. The other set of hydraulic cylinders 302 has a second support plate 304 installed at the telescopic end. A motor 305 is installed on the upper end of the movable frame 301, and guide rails are symmetrically installed. A slider moves on the guide rails, and a movable plate 307 is connected to the slider. A first support plate 308 is installed on the upper end of the movable plate 307. The anchor drilling rig 4 is installed on the upper end of the first support plate 308. A bearing seat is also installed on the upper end of the movable frame 301. The output end of the motor 305 is connected to a threaded shaft 306. The end of the threaded shaft 306 is connected to the inner ring of the bearing seat. The threaded shaft 306 and the movable plate 307 form a threaded connection.

[0024] In this implementation plan, the specific working principle is as follows: When adjusting the anchor drilling rig 4, the rotation angle is adjusted by rotating the base structure 1, and then the height and angle are adjusted by adjusting the structure 2. When the adjustment is in the appropriate position, the motor 305 drives the threaded shaft 306 to rotate, which in turn drives the moving plate 307 to move, thus moving the anchor drilling rig 4. Before moving, the two sets of hydraulic cylinders 302 are started simultaneously, so that the guide plate 303 and the second support plate 304 contact the coal bunker surface. This can stabilize the overall structure and prevent the structure from tilting due to the reverse force when the drilling rig moves, which would affect the drilling quality.

[0025] Based on the above, in order to provide support for the first support plate 308 and prevent downward tilting, please refer to the following for details. Figure 6 As can be seen, a second support wheel 309 is also installed on the upper end of the movable frame 301, and the second support wheel 309 is in contact with the lower end face of the first support plate 308.

[0026] Two sets of hydraulic cylinders, 302, are available for details. Figure 6 As can be seen, the distance between the two sets of hydraulic cylinders 302 and the port of the corresponding moving frame 301 is the same, and plates with openings are installed on both ends of the moving frame 301, through which the telescopic end of the hydraulic cylinder 302 passes.

Figure 1 and Figure 3 , Figure 4 As can be seen, the rotating base structure 1 includes a chassis 101, an inner box 102, a geared motor 103, a bearing seat 104, a gear 105, a transmission gear 106, a turntable 107, and a rotating disc 108;

[0028] The chassis 101 has an opening on its end face. An internal housing 102 is installed on the inner top surface of the chassis 101. A bearing seat 104 is installed on the inner side of the internal housing 102. A gear motor 103 is installed on the lower end face of the internal housing 102. A shaft is connected to the output end of the gear motor 103. The surface of the shaft is connected to the inner ring of the bearing seat 104. A gear 105 is installed at the end of the shaft. A turntable 107 is installed on the upper end of the chassis 101. A transmission gear 106 is installed on the lower end face of the turntable 107. The transmission gear 106 meshes with the gear 105 for transmission. A rotating disk 108 is installed on the upper end of the turntable 107. The gear 105 is driven to rotate by the gear motor 103, which in turn drives the transmission gear 106 to rotate, causing the turntable 107 to rotate, which in turn drives the rotating disk 108 to rotate, thereby driving the adjustment structure 2 to rotate and adjust.

[0029] To improve the stability of the rotating disk 108 during rotation, please refer to [the relevant documentation]. Figure 3 As can be seen, the upper surface of the chassis 101 has support wheels 109 arranged in a ring array.

Figure 5 As can be seen, the adjustment structure 2 includes a mounting base 201, a second geared motor 202, a guide rail 203, a movable seat 204, a first threaded shaft 205, and a rotating base 206. The mounting base 201 is mounted on the upper surface of the chassis 101. The second geared motor 202 is mounted on the upper surface of the mounting base 201. The output end of the second geared motor 202 is connected to the first threaded shaft 205. The inner side of the mounting base 201 is symmetrically equipped with guide rails 203 to facilitate the movement of the movable seat 204. A slider is movable on the guide rail 203. The movable seat 204 is connected to the slider. The rotating base 206 is mounted on the outer side of the movable seat 204. The second geared motor 202 drives the first threaded shaft 205 to rotate, thereby driving the movable seat 204 to move in height. At this time, the tilt angle can be adjusted by the rotating base 206 mounted on the movable seat, so as to meet the drilling needs of different positions.
