Description

Technical Field

[0001] The present disclosure relates to the technical field of drilling rig support devices, and particularly to an angle adjustment device and an adjustment method for a raise boring machine. Background Art

[0002] A raise boring machine drives a hydraulic motor through an electric motor. The hydraulic motor drives a swivel, and uses hydraulic power to transmit torque to a drill string system, driving a drill pipe and a drill bit to rotate. The drill bit or hob rolls under the action of a drilling pressure, generating an impact load, so that the hob impacts, extrudes, and shears the rock, thereby breaking the rock; however, in some cases, not all drilling rigs are vertically downward, and the angle of the drilling rig needs to be adjusted.

[0003] In the related art known to the inventors, the angle adjustment of the drilling rig is mostly achieved by the lifting of a hydraulic cylinder. Specifically, one end of a bracket for fixing the drilling rig is hinged to a base, and at the same time, it is hinged to the hydraulic cylinder in the middle. The other end of the hydraulic cylinder is hinged to the base, and the angle between the bracket and the base is changed by the lifting and lowering of the hydraulic cylinder.

[0004] However, the inventors found that when implementing the above solution, the above structure can only achieve angle adjustment and cannot achieve angle fixation. During specific drilling operations, the reverse force on the drilling rig is likely to cause a large tensile force on the hydraulic cylinder, which may lead to damage to the hydraulic cylinder.

[0005] The information disclosed in this background art section is only intended to deepen the understanding of the overall background art of the present disclosure, and should not be regarded as an admission or any form of implication that this information constitutes the prior art known to those skilled in the art.

[0043] Embodiment 1

[0044] As Figures 1 to 6 shown, the raise boring machine angle adjustment device includes a base 10, a first screw 20, a slider 30, a second screw 40 and a connecting sleeve 50, wherein:

[0045] As Figure 3As shown, the base 10 is provided with a chute 11 arranged in a straight line direction; the function of the chute 11 is to provide guidance and limitation for the movement of the slider 30. On the one hand, the two side walls of the chute 11 are used to prevent the slider 30 from shifting during movement. On the other hand, the second locking member 12 provided on the side wall of the chute 11 is used to position the slider 30. When the slider 30 moves to the set position, the second locking member 12 is used to fix the slider 30, so that the position of the slider 30 is locked;

[0046] One end of the first screw 20 is rotatably connected to the inside of the chute 11 of the base 10; as Figure 1 shown, the first screw 20 is arranged at the right side position of the base 10. Here, the rotatable connection means hinged connection. The bottom of the first screw 20 is connected to the base 10 by means of a pin or other rotating shaft to realize the angle adjustment of the first screw 20;

[0047] The slider 30 is slidably arranged in the chute 11; the second screw 40 is rotatably connected to the slider 30 and is arranged in the same plane as the first screw 20; as Figure 1 shown, a connecting seat is convexly arranged on the part of the slider 30 protruding from the base 10. The connecting seat is connected to the second screw 40 by a pin, so as to realize the angle adjustment of the second screw 40. By arranging the first screw 20 and the second screw 40 in the same plane, it is convenient to fix the drill rig through the connecting sleeve 50;

[0048] The connecting sleeves 50 are respectively sleeved on the first screw 20 and the second screw 40, and the opposite surfaces of the two connecting sleeves 50 have hole positions for connecting with the drill rig; please continue to refer to Figure 1 , in the embodiment of the present disclosure, the function of the connecting sleeve 50 is to fix the drill rig and ensure that the first screw 20 and the second screw 40 always remain parallel after being connected to the drill rig. Since the width of the drill rig is fixed, it is equivalent to that the first screw 20 and the second screw 40 always remain parallel and have the same spacing after being connected to the drill rig.

[0049] Among them, both ends of the connecting sleeve 50 have a first locking member 51 for locking the positions of the two connecting sleeves 50, and the base 10 also has a second locking member 12 for locking the position of the slider 30 in the chute 11; it should be noted here that the first locking member 51 and the second locking member 12 are respectively used to fix the position of the connecting sleeve 50 on the screw and the position of the slider 30 in the chute 11. The above-mentioned locking methods have various forms in the art, such as locking by nuts and locking by screw positioning holes, etc., which all fall within the protection scope of the present disclosure;

[0050] In the embodiment of the present disclosure, when specifically adjusting the angle, please refer to Figure 1 andFigure 2 Adjust the position of the slider 30 within the sliding groove 11, and simultaneously adjust the position of the connecting sleeve 50 on the first screw rod 20 and / or the second screw rod 40; when the position of the slider 30 is fixed, the positions of the two connecting sleeves 50 are fixed and fixedly connected to the drill rig, the angle of the drill bit on the drill rig is fixed. This fixed direction is equivalent to fixing the right-angled side of a right-angled trapezoid, adjusting the length of the hypotenuse and the lengths of the two parallel sides to achieve angle adjustment;

[0051] Through the above settings, the adjustment of the drill bit angle is achieved only through a pure mechanical connection structure. Compared with the prior art, there is no need to use a hydraulic cylinder, which further avoids the damage of the hydraulic cylinder and improves the stability during the drilling process; it should be noted here that in the embodiment of the present disclosure, there are two such angle adjustment devices, which are respectively arranged on both sides of the drill rig, thereby further ensuring the stability and reliability of the drill rig;

[0052] In the above embodiment, by rotatingly connecting the first screw rod 20 to the base 10, hinging the second screw rod 40 to the slider 30 and enabling the slider 30 to move within the sliding groove 11, the two screw rods are always kept parallel and equidistant. And through the setting of the connecting sleeve 50 and the adjustable setting of the distance of the connecting sleeve 50 on the first screw rod 20 and the second screw rod 40, the angle adjustment of the drill pipe on the drill rig fixed to the connecting sleeve 50 is achieved. And through the fixed connection between the drill rig and the connecting sleeve 50, the locking of the position of the connecting sleeve 50 by the first locking member 51 and the fixing of the position of the slider 30 by the second locking member 12, the fixing of the drill pipe angle is achieved. Compared with the related art, the use of a pure mechanical connection improves the reliability of angle adjustment, avoids the use of an oil cylinder, and reduces the waste of resources.

[0053] Based on the above embodiment, regarding the specific form of the first locking member 51, please refer to Figure 1 and Figure 2 , in the embodiment of the present disclosure, the two connecting sleeves 50 are respectively slidably sleeved on the first screw rod 20 and the second screw rod 40, and the first locking member 51 is a nut screwed on the first screw rod 20 and the second screw rod 40. In this way, during specific adjustment, first loosen the nut, then move the position of the connecting sleeve 50 on the screw rod. When the position adjustment is completed, then screw the nut so that the nut is locked at both ends of the connecting sleeve 50. Of course, it should be noted here that in order to ensure the reliability of locking, several more nuts can be provided at both ends of the connecting sleeve 50, and the above structural form still falls within the protection scope of the present disclosure.

[0054] Regarding the locking structure of the slider 30, as Figure 4As shown in [reference], in the embodiment of the present disclosure, the second locking member 12 includes a locking screw 12a screwed on the side wall of the sliding groove 11 and a wedge block 12b rotatably connected to the locking screw 12a. The wedge block 12b abuts against the side wall of the slider 30. Specifically, holes can be drilled in the two side walls first, and then nuts are welded. Through the relative rotational connection between the locking screw 12a and the wedge block 12b, when the locking screw 12a is turned, the wedge block 12b approaches or moves away from the side wall of the slider 30. In this way, by abutting against the two side walls of the slider 30, the friction force of the slider 30 moving in the sliding groove 11 is increased, thereby realizing the fixation of the slider 30;

[0055] In order to further improve the friction force between the slider 30 and the wedge block 12b, in the embodiment of the present disclosure, please continue to refer to Figure 4 , on the surface of the slider 30 opposite to the wedge block 12b, there is a wedge-shaped groove 31 arranged in the direction of the side wall of the wedge block 12b. Through the above setting, as the moving distance of the wedge block 12b towards the side wall of the slider 30 increases, the contact area between the wedge-shaped groove 31 and the wedge block 12b is further increased, thereby further improving the friction force between the two;

[0056] On the basis of the above embodiment, in the embodiment of the present disclosure, as shown in Figure 4 , the bottom surface of the wedge-shaped groove 31 is arranged parallel to the bottom surface of the wedge block 12b, and there are teeth on the bottom surfaces of the wedge-shaped groove 31 and the wedge block 12b that can be meshed with each other. It should be noted here that in the embodiment of the present disclosure, the arrangement direction of the teeth is perpendicular to the moving direction of the slider 30, and a plurality of teeth are evenly distributed along the moving direction of the slider 30. When the wedge block 12b moves to the bottom close to the side wall of the slider 30, the teeth on the bottom surface of the wedge block 12b are meshed with the teeth on the side wall of the slider 30, forming a locking structure, thereby further improving the locking reliability of the slider 30;

[0057] Please continue to refer to Figure 2 , in the embodiment of the present disclosure, the sliding groove 11 also has a locking screw 13 in the moving direction of the slider 30. The locking screw 13 is screwed at both ends of the sliding groove 11 in a direction parallel to the sliding groove 11 for locking the position of the slider 30. It should be noted here that in the embodiment of the present disclosure, the locking screw 13 can be implemented as the second locking member 12, or on the basis of the above embodiment of the wedge block 12b, it can further be used as a supplementary means to prevent the slider 30 from moving. The above two methods and their combinations all fall within the protection scope of the present disclosure.

[0058] Embodiment Two

[0059] In the second embodiment of the present disclosure, for the movement of the slider 30, in the first embodiment, it is mostly carried out by manual movement. In order to further improve the stability and reliability of the movement, in the embodiment of the present disclosure, another form of driving the slider 30 is also provided, such as Figure 5 As shown in Figure 5 , at the end of the chute 11 away from the first screw 20, there is also a motor 60. A lead screw 70 is connected to the rotating shaft of the motor 60. The lead screw 70 is screwed to the slider 30 and is used to drive the slider 30 to move in the chute 11. Of course, it should be noted here that there is also a track for the slider 30 to slide in the chute 11. In this way, by rotating the motor 60, the movement of the slider 30 can be realized. When the size and weight of the slider 30 are large, by rotating the lead screw 70 by the motor 60, the construction difficulty can be reduced and the adjustment efficiency can be improved;

[0060] In the embodiment of the present disclosure, another structural form is provided for the connecting sleeve 50. The structures and connection methods of the other components are the same as those in the first embodiment above and will not be elaborated here; as Figure 6 and Figure 7 As shown in Figure 6 and Figure 7 , in the embodiment of the present disclosure, the connecting sleeve 50 is not slidably arranged relative to the axial direction of the screw, but a nut sleeve 50a is rotatably arranged relative to the axial direction of the connecting sleeve 50. The inner wall of the nut sleeve 50a is screwed to the first screw 20 or the second screw 40. In this way, through the setting of the nut sleeve 50a and the relative rotatable setting of the nut sleeve 50a and the connecting sleeve 50, as Figure 6 and Figure 7 As shown in Figure 6 and Figure 7 , the position of the connecting sleeve 50 is adjusted by rotating the nut sleeve 50a. Through the setting of this structural form, the reliability of the position locking of the connecting sleeve 50 can be ensured, and through the meshing of the nut sleeve 50a and the screw, the thread is also protected to a certain extent, improving the service life of the screw;

[0061] In the embodiment of the present disclosure, an angle adjustment method for the above-mentioned raise boring machine angle adjustment device is also provided, such as Figure 8 As shown in Figure 8 , the method includes the following steps:

[0062] S10: Remove the connection between the drill rig and the connecting sleeve 50 on the second screw 40; as Figure 1 As shown in Figure 1 , in the embodiment of the present disclosure, the drill rig and the connecting sleeve 50 are connected by fasteners. Removing the connection between the two here means removing the bolt from the connection hole to realize the adjustment of the angle and position of the second screw 40;

[0063] S20: Release the second locking member 12 on the slider 30 to enable the slider 30 to slide freely within the chute 11. It should be noted here that the order between steps S10 and S20 is not limited in the embodiments of the present disclosure. Those skilled in the art can implement any one of the above steps first, and regardless of the implementation order, it falls within the protection scope of the present disclosure.

[0064] S30: Adjust the first screw 20 to a set angle. After the connection between the drill rig and the second screw 40 is released, the angle of the first screw 20 can be adjusted. When specifically implementing, certain auxiliary means, such as an angle gauge, can be used to achieve the adjustment of the set angle.

[0065] S40: Adjust the angle of the second screw 40 to be parallel to the first screw 20, and move the slider 30 so that the connecting sleeve 50 on the second screw 40 meets the requirements for docking with the drill rig. Since the angles of the first screw 20 and the second screw 40 with respect to the horizontal plane have changed, and at this time, since the width of the drill rig is fixed, when the first screw 20 and the second screw 40 remain parallel and the spacing remains unchanged but the angle of the hypotenuse has changed, the length of the hypotenuse must change. Therefore, by moving the slider 30, the calibration of the hypotenuse length after the angle change is achieved. After calibrating the hypotenuse length, due to the angle change, the relative position of the connecting sleeve 50 on the second screw 40 with respect to the connecting sleeve 50 on the first screw 20 has also changed. Therefore, the position of the connecting sleeve 50 on the second screw 40 also needs to be adjusted.

[0066] S50: Adjust the position of the connecting sleeve 50 on the second screw 40 to achieve the connection of the drill pipe. The position adjustment mentioned above has been described above and will not be elaborated here. By adjusting the connection line of the two connecting sleeves 50 to be perpendicular to the first screw 20 and the second screw 40, locking can be performed. It should also be noted here that the operation order of steps S40 and S50 is not limited in the embodiments of the present disclosure. Those skilled in the art can perform either step first or simultaneously according to needs, and the above implementation orders all fall within the protection scope of the present disclosure.

[0067] S60: Fix the position of the slider 30 to fix the angle of the drill rig. After the angle adjustment is completed and the position of the connecting sleeve 50 is adjusted and fixed, the last step is to fix the position of the slider 30. After fixing the position of the slider 30, one last step is required, that is, after releasing the connection between the drill rig and the connecting sleeve 50 on the second screw 40 in step S10, the two need to be connected and fixed. After the fixing is completed, it is equivalent to fixing the right-angle sides of the right trapezoid. Through the above method, reliable fixation of the drill rig angle adjustment is achieved.

[0068] It should also be noted here that in the embodiments of the present disclosure, the angle adjustment range of the raise boring rig angle adjustment device is 60 to 90 degrees, and this angle adjustment range is the angle between the drill pipe and the horizontal plane. That is, when the drill pipe is vertically downward, it is 90 degrees, and when it is inclined, it is 60 to 90 degrees. The above structure in the embodiments of the present disclosure can achieve any angle adjustment between 60 and 90 degrees, has strong applicability, high service life, and is suitable for popularization and use.

[0069] Those skilled in the art should understand that the present disclosure is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present disclosure. Without departing from the spirit and scope of the present disclosure, the present disclosure will have various changes and improvements, and these changes and improvements all fall within the scope of the present disclosure claimed.
