[0018] The utility model is an all-round hydraulic drilling vehicle, such as Figure 1-3As shown, it includes a crawler vehicle 1, on which a hydraulic station 2 is installed. The crawler vehicle 1 serves as the traveling mechanism of the entire machine and can enable the drilling vehicle to travel underground in the mine, while the hydraulic station 2 can provide the necessary hydraulic oil as input power for the movement mechanism of the entire machine.

[0019] To achieve full adjustment of the drilling rig on the rig, a horizontally arranged platform frame 4 is mounted at the front end of the crawler vehicle 1 via a first slewing bearing 3. The platform frame 4 can rotate horizontally relative to the crawler vehicle 1. Two sets of upper jacking cylinders 5 are mounted side by side on the platform frame 4. The piston rods of the upper jacking cylinders 5 are equipped with upward-facing first support seats 6. When the entire rig reaches the set drilling position, the piston rods of the upper jacking cylinders 5 extend to press the first support seats 6 against the ceiling of the underground mine tunnel, thus achieving the positioning of the entire rig.

[0020] A vertically arranged lifting cylinder 7 is provided on the platform frame 4 on one side of each upper tightening cylinder 5. The piston rod of the lifting cylinder 7 is hinged on the platform frame 4. A lifting frame 8 is provided on the cylinder barrel of the lifting cylinder 7. One end of the lifting frame 8 is provided with a guide sleeve 9 that cooperates with the cylinder barrel of the upper tightening cylinder 5. When the piston rod of the lifting cylinder 7 is extended or retracted, it can drive the lifting frame 8 to move vertically up and down along the height direction of the upper tightening cylinder 5.

[0021] A rotatable tilting frame 10 is mounted between the two lifting frames 8. Rotation of the tilting frame 10 can be achieved via a rotary motor, slewing bearing, or a slider-crank mechanism. The piston rod of the lifting cylinder 7 is extended and retracted to drive the tilting frame 10 vertically. A rock bolter 12 is mounted on the tilting frame 10 via a second slewing bearing 11, allowing for rotational adjustment relative to the tilting frame 10.

[0022] Through the above-mentioned position adjustment mechanism, the horizontal rotation adjustment, vertical height adjustment, flip adjustment and vertical rotation adjustment of the drilling rig on the drilling vehicle can be realized, that is, the drilling rig can be adjusted horizontally by ±90° and vertically by ±90°, and can meet the drilling needs of different heights and angles under the premise of vehicle body positioning.

[0023] Furthermore, in order to realize the rotation adjustment of the turnover frame 10 relative to the lifting frame 8 and to realize the stability of the connection structure between the lifting frame 8 and the turnover frame 10, it is sufficient to bear the weight of the upper drilling rig and the vibration amplitude of the buffer operation while rotating. Figure 4 and Figure 5 As shown, a first tilting shaft 13 is installed between the lifting frame 8 and the tilting frame 10. A connecting shaft 14 is installed between the lifting frames 8 on both sides. Two sets of angle adjustment cylinders 15 are arranged side by side between the tilting frames 10 and the connecting shaft 14. The piston rod of each angle adjustment cylinder 15 is fitted onto the connecting shaft 14 through an earring. A second tilting shaft 29 is installed between the cylinder barrel of the angle adjustment cylinder 15 and the tilting frame 10.

[0024] The extension and retraction of the piston rod of the angle adjustment cylinder 15 can drive the turning frame 10 and the anchor drill rig 12 thereon to rotate relative to the lifting frame 8 with the first turning axis 13 as the axis, and no interference will be generated with other mechanisms on the platform frame 4 during the extension and retraction process of the piston rod of the angle adjustment cylinder 15.

[0025] Furthermore, in order to ensure the relative stability of the drilling position of the anchor drill rig 12 after the anchor drill rig 12 is adjusted into place during the drilling operation, Figure 6 As shown, a horizontally arranged front support cylinder 16 is installed at the front end of the guide rail frame of the anchor drilling machine 12, and a second support seat 17 is installed on the piston rod of the front support cylinder 16. Figure 7 As shown, the rear end of the guide rail frame of the anchor drilling rig 12 is equipped with two groups of rear support cylinders 18 arranged side by side, wherein the piston rods of the rear support cylinders 18 are hinged to the guide rail frame, and the side of the guide rail frame is provided with a limiting ring 19 that cooperates with the cylinder barrel of the rear support cylinder 18, and the cylinder barrel ends of the rear support cylinders 18 on both sides are equipped with rear support frames 20, and the rear support frames 20 are equipped with a third support seat 21.

[0026] After the anchor drill rig 12 is adjusted into place, the piston rod of the front support cylinder 16 extends to allow the second support seat 17 to be pressed tightly against the wall of the tunnel under the mine. At the same time, the piston rod of the rear support cylinder 18 extends to allow the third support seat 21 to be pressed tightly against the wall of the tunnel under the mine, forming a support lock for the front and rear positions of the drill rig, ensuring the stability of the drill rig position during the drilling operation.

[0027] Furthermore, to enhance the connection strength between the upper jacking cylinder 5 and the platform frame 4, a bottom plate 22 is provided at the bottom of the cylinder barrel of the upper jacking cylinder 5, and the bottom plate 22 is fastened to the platform frame 4 by bolts. Vertically arranged ribs 23 are also provided on the bottom plate 22, and the ribs 23 are fixedly connected to the cylinder barrel of the upper jacking cylinder 5. The piston rod of the lifting cylinder 7 is hingedly mounted between the ribs 23 on both sides.

[0028] Furthermore, in order to keep the whole machine firmly positioned in the tunnel during drilling operation, side support mechanisms are provided on both sides of the crawler vehicle 1, such as Figure 8 As shown, the side support mechanism includes a side support cylinder 24, with a fourth support seat 25 mounted on the piston rod of the side support cylinder 24. The crawler vehicle 1 is provided with an articulated seat 26 that cooperates with the cylinder barrel of the side support cylinder 24. The articulated seat 26 is connected to the cylinder barrel of the side support cylinder 24 via an articulated shaft 27. The side support cylinder 24 can be rotated and adjusted relative to the articulated seat 26 to adjust the position of the side support cylinder 24 according to the actual situation in the tunnel. When the piston rod of the side support cylinder 24 is extended, the fourth support seat 25 can be pressed against the tunnel wall to achieve stable support.

[0029] In order to prevent the side support mechanisms on both sides from affecting the normal movement of the entire machine in the tunnel, a detachable locking pin 28 is provided on the articulated seat 26, and a socket that matches the locking pin 28 is provided on the cylinder barrel of the side support cylinder 24. When the locking pin 28 is in the socket, the side support cylinder 24 is arranged vertically and will not extend out of the two sides of the crawler vehicle 1, will not increase the width of the entire machine, and ensure that the entire machine is compact.

[0030] like Figure 9-12 As shown, high-efficiency drilling in different postures of the drilling vehicle can be achieved by adjusting the first slewing bearing 3, the lifting cylinder 7, the angle adjustment cylinder 15, and the second slewing bearing 11.

[0031] The guide rail of the drilling vehicle works in the posture of -90 degrees to 90 degrees: first, the lifting cylinder 7 is controlled to work to make the turning frame 10 rise to a certain height, and then the angle adjustment cylinder 15 is controlled to work to make the turning frame 10 rotate around the first turning axis 13, and stop rotating when the axis of the guide rail is parallel to the vertical plane; further controlling the second slewing bearing 11 installed under the guide rail can make the guide rail rotate from -90 degrees to 90 degrees, thereby realizing efficient drilling work of the drilling rig at -90 degrees to 90 degrees.

[0032] The following steps are used for side drilling and head-on drilling: First, the lifting cylinder 7 is controlled to raise the tilting frame 10 to a certain height. Then, the angle adjustment cylinder 15 is controlled to rotate the tilting frame 10 around the first tilting axis 13. The rotation stops when the axis of the guide rail is parallel to the vertical plane. Then, the first slewing bearing 3 installed under the platform frame 4 is controlled to rotate the platform frame 4, thereby driving the guide rail to rotate. After reaching the appropriate position, the slewing bearing is stopped, causing the guide rail to stop. The second slewing bearing 11 installed under the guide rail is further controlled. The guide rail is not constrained to the platform frame 4. As the platform frame 4 rotates, the guide rail can also rotate independently of each other. This allows the drill carriage guide rail to be used in both side drilling and head-on drilling positions, achieving efficient drilling.
