[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] According to the attached Figure 1-5 As shown, the embodiment of the utility model provides a crawler-type fully hydraulic tunnel drilling rig which is convenient for positioning, including a drilling rig chassis 1, a fixed frame 2 is arranged on the top and near the left end of the drilling rig chassis 1, an adjusting seat 21 is slidably connected to the inner side of the fixed frame 2, an adjusting mechanism for adjusting the position of the adjusting seat 21 is installed on the fixed frame 2, a lifting frame 3 is arranged above the adjusting seat 21, a lifting mechanism connected to the adjusting seat 21 is arranged at the bottom of the lifting frame 3, a control mechanism is arranged above the lifting frame 3, the control mechanism includes a control frame 4 and a guide frame 5, a hydraulic motor 6 is arranged on the top of the guide frame 5, a drill rod 61 is connected to the left side of the hydraulic motor 6, a ring laser 63 is arranged on the outer side of the drill rod 61 and near the left edge, a support mechanism for improving stability is arranged on the front and rear sides of the drilling rig chassis 1, and the support mechanism includes a front and rear symmetrical abutment plate 7.

[0027] When the tunnel drilling rig is used inside the tunnel, it is inconvenient to adjust the drill rod due to the narrow interior of the tunnel, which in turn affects the positioning accuracy of the drill rod. This solution drives the adjustment seat 21 to move through the adjustment mechanism, so that the adjustment seat 21 can drive the lifting frame 3 to move, thereby fine-tuning the drill rod 61 left and right along the drilling direction, which is convenient for positioning the drill rod 61 and avoids oblique drilling of the drill rod 61 and affecting the drilling accuracy. In addition, during the drilling process, the lifting frame 3 can be raised and lowered by the lifting mechanism to adjust the drilling height of the drill rod 61. The hydraulic motor 6 and the drill rod 61 can be further adjusted and controlled through the cooperation of the control frame 4 and the guide frame 5, thereby facilitating the positioning of the drilling position.

[0028] Furthermore, during the positioning process, the ring laser 63 is operated, and through the cooperation of multiple groups of laser emission heads on the ring laser 63, a ring light beam can be formed along the outer edge of the drill rod 61, and a ring aperture can be formed on the tunnel wall to position the drill rod 61, thereby ensuring the accuracy of the drill rod 61 during drilling.

[0029] An oil tank 11 is arranged on the top of the drilling rig chassis 1 and near the right edge, and a control assembly 12 is arranged above the oil tank 11. The oil tank 11 can supply oil to the first hydraulic cylinder 33, the second hydraulic cylinder 41, the third hydraulic cylinder 71 and the fourth hydraulic cylinder 72, and can be controlled by the control assembly 12, so as to facilitate the regulation of the drilling position of the drill rod 61.

[0031] When the first motor 24 drives the first screw rod 23 to rotate, the adjustment seat 21 can slide along the slide rod 22 and fine-tune the drill rod 61 left and right along the drilling direction, so as to facilitate positioning of the drilling position of the drill rod 61 and avoid drastic adjustment of the drilling rig.

[0033] When the first hydraulic cylinder 33 is in operation, it can drive the four groups of telescopic rods 31 to telescopically move, and drive the lifting frame 3 to move, so that the height of the drill rod 61 can be adjusted through the lifting frame 3, so that the drill rod 61 can be conveniently drilled at different heights.

[0034] The control frame 4 is arranged above the lifting frame 3, and the right end is rotatably connected to the lifting frame 3. A penetrating strip groove 34 is opened on the lifting frame 3. An obliquely distributed second hydraulic cylinder 41 is provided below the control frame 4 and on the inner side of the strip groove 34. Both ends of the second hydraulic cylinder 41 are rotatably connected with connecting blocks 42, and the connecting block 42 at one end is welded and fixed to the lifting frame 3, and the connecting block 42 at the other end is welded and fixed to the control frame 4.

[0035] When the second hydraulic cylinder 41 is in operation, it can push the right end of the control frame 4 to rotate on the lifting frame 3, and make the control frame 4 drive the guide frame 5 to rotate, so as to adjust the inclination of the drill rod 61.

[0036] The guide frame 5 is welded and fixed above the control frame 4 and close to the right edge. A mounting box 51 is provided on the left side of the guide frame 5. The bottom end of the hydraulic motor 6 is slidably connected to the guide frame 5. A second screw 52 for driving the hydraulic motor 6 to move is provided on the inner side of the guide frame 5. A second motor 53 coaxially driven with the second screw 52 is installed on the inner side of the mounting box 51.

[0037] When the second motor 53 drives the second screw rod 52 to rotate, the hydraulic motor 6 can be driven to move along the guide frame 5, and the hydraulic motor 6 drives the drill rod 61 to move, so that the hydraulic motor 6 drives the drill rod 61 to perform drilling work.

[0038] The drill rod 61 is coaxially driven with the output shaft of the hydraulic motor 6. A positioning frame 62 is installed on the top of the installation box 51. A positioning ring 621 is welded and fixed on the side wall of the positioning frame 62 and on the outside of the drill rod 61.

After that, the fourth hydraulic cylinder 72 is running to drive the fixed plate 73 to move downward, so that the bottom of the fixed plate 73 is in contact with the ground of the tunnel, so that the supporting mechanism can support and fix at multiple angles, improve the stability of the drilling rig chassis 1, and avoid the drill rod 61 from deviating during the drilling process and affecting the positioning accuracy.

[0041] When the crawler-type fully hydraulic tunnel drilling rig of the utility model is used, first, the drilling rig is moved as a whole to the inside of the tunnel, and then the third hydraulic cylinder 71 is operated to drive the abutment plate 7 to move, so that the abutment plate 7 is in close contact with the side wall of the tunnel, and then the fourth hydraulic cylinder 72 is operated to drive the fixed plate 73 to contact with the ground of the tunnel, so as to support the chassis 1 of the drilling rig at multiple angles;

[0042] Furthermore, when drilling, the ring laser 63 emits a ring laser beam and irradiates the tunnel wall to form an annular aperture, through which the drilling position is located.
