Technical Field

[0001] The present invention relates to the technical field of bolt drills, and more particularly, to a drill pipe guiding mechanism and a bolt drill having the same. Background Art

[0002] Coal mining requires a large number of roadways to be excavated underground. Keeping the roadways unobstructed and the surrounding rock stable is of great significance for coal mine construction and safe production.

[0003] In the existing roadway support technology, bolt and cable support technologies are mostly used. When performing bolt support, first, a deep hole is drilled into the roof through the drill pipe of a bolt drill, and then the bolt is sent into the hole and anchored.

[0004] However, most of the bolt drills currently used in coal mines do not have a drill pipe guiding mechanism. When drilling, due to the long drill pipe and the need to advance forward while rotating, the swing amplitude of the drill pipe is very large, which causes problems such as difficult and inaccurate hole positioning that need to be solved urgently. The existing drill pipe guiding mechanisms have complex structures and large volumes, with a small scope of application and are difficult to be popularized on a large scale. Summary of the Invention

Detailed implementation manners

[0037] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0038] As Figures 1 to 8 shown, the present invention provides a drill pipe guiding mechanism 60 for guiding and supporting the movement of the drill pipe 210 of an anchor drill. The drill pipe guiding mechanism 60 includes: a plurality of guiding parts 1, which are arranged around the outer peripheral surface of the drill pipe 210. Each guiding part 1 has a contact position for contacting the drill pipe 210 to guide and support the movement of the drill pipe 210 and a relaxation position for separating from the drill pipe 210 to release the drill pipe 210. Each guiding part 1 is movably arranged between the contact position and the relaxation position.

[0039] The drill pipe guiding mechanism 60 of the present invention is used to guide and support the movement of the drill pipe 210 of an anchor drill. The drill pipe guiding mechanism 60 includes: a plurality of guiding parts 1, which are arranged around the outer peripheral surface of the drill pipe 210. Each guiding part 1 has a contact position for contacting the drill pipe 210 to guide and support the movement of the drill pipe 210 and a relaxation position for separating from the drill pipe 210 to release the drill pipe 210. Each guiding part 1 is movably arranged between the contact position and the relaxation position. In this way, by arranging the above-mentioned drill pipe guiding mechanism 60 with simple structure, small volume and flexible and reliable action on the anchor drill, the drill pipe of the anchor drill can be smoothly and reliably advanced forward during the drilling process, improving the working efficiency of the anchor drill and ensuring the quality of the drilled hole, and solving the problems such as difficult hole positioning and inaccurate positioning caused by the large swing amplitude of the drill pipe when the anchor drill used in the coal mine underground in the prior art drills holes.

[0040] As Figure 1 and Figure 2 shown, the anchor drill includes a carriage mechanism 30 and a rotary mechanism 20 which is reciprocally movable along a predetermined direction on the carriage mechanism 30. The drill pipe 210 is arranged on the rotary mechanism 20 to move and rotate under the drive of the rotary mechanism 20; wherein, a plurality of guiding parts 1 are installed on the carriage mechanism 30, and the plurality of guiding parts 1 are located on the side of the carriage mechanism 30 close to the rotary mechanism 20 where the drill pipe 210 is located.

[0041] As Figure 9 shown, a plurality of guiding columns 310 for installing the rotary mechanism 20 and parallel to the predetermined direction are arranged on the carriage mechanism 30 to guide the movement of the rotary mechanism 20; wherein, the plurality of guiding parts 1 are respectively arranged in one-to-one correspondence with the plurality of guiding columns 310 of the carriage mechanism 30. Each guiding part 1 includes a first sleeve part 13, and the first sleeve part 13 is rotatably sleeved on the corresponding guiding column 310 so that each guiding part 1 rotates on the corresponding guiding column 310.

[0042] In at least one embodiment of the present invention, the number of the guiding parts 1 is two, and the two guiding parts 1 are respectively located on the opposite sides of the drill pipe 210.

[0043] Specifically, the carriage mechanism 30 includes two support plates 320 arranged oppositely, and the two support plates 320 are connected by four guide columns 310. Among the four guide columns 310, every two form a group, and there are two groups of guide columns 310 in total. These two groups of guide columns 310 are arranged at intervals in a direction perpendicular to the support base surface of the anchor drill. The two guide columns 310 in each group are arranged at intervals in a direction parallel to the support base surface of the anchor drill. The slewing mechanism 20 is installed on the two guide columns 310 on the side away from the support base surface, and the first sleeve parts 13 of the two guiding parts 1 are respectively sleeved on the two guide columns 310 on the side away from the support base surface.

[0044] As Figures 3 to 6 shown, each guiding part 1 further includes a guiding wheel 12 and a connecting arm 11 which are connected. The guiding wheel 12 is connected to the first sleeve part 13 through the connecting arm 11, so that the guiding wheel 12 contacts or separates from the drill pipe 210 through the rotation of the first sleeve part 13.

[0045] Since the drill pipe 210 can rotate around its own axis for drilling, the guiding wheel 12 is rotatably arranged. When the drill pipe 210 rotates, the guiding wheel 12 can also be driven by the drill pipe 210 to rotate, so as to reduce the frictional loss between the guiding wheel 12 and the drill pipe 210 and extend the service life of the guiding wheel 12 and the drill pipe 210.

[0046] Specifically, the guiding wheel 12 is made of an elastic material, and the elastic material can be rubber, resin, etc.

[0047] As Figure 1 and Figure 2 shown, the drill pipe guiding mechanism 60 further includes a plurality of guiding driving parts 2. The plurality of guiding driving parts 2 are arranged in one-to-one correspondence with the plurality of guiding parts 1 to respectively drive the corresponding guiding parts 1 to move from the contact position to the relaxation position.

[0048] Specifically, each guiding driving part 2 is installed on the slewing mechanism 20 and on the side of the slewing mechanism 20 close to the guiding part 1 to move along with the slewing mechanism 20; when the slewing mechanism 20 moves to the position where the plurality of guiding driving parts 2 respectively contact the corresponding guiding parts 1, the plurality of guiding driving parts 2 respectively drive the corresponding guiding parts 1 to move.

[0049] As Figures 1 to 4 shown, the drill pipe guiding mechanism 60 further includes: a return elastic member 3. The return elastic member 3 is connected to the guiding part 1 to make the plurality of guiding parts 1 return from the relaxation position to the contact position through the return elastic member 3.

[0050] In at least one embodiment of the present invention, the number of the guiding parts 1 is two, and the two guiding parts 1 are respectively located on opposite sides of the drill pipe 210. The two ends of the return elastic member 3 are respectively connected to the two guiding parts 1 in one-to-one correspondence, so that the plurality of guiding parts 1 can return from the relaxed position to the contact position through the return elastic member 3.

[0051] Preferably, the return elastic member 3 is a tension spring.

[0052] As Figure 3 and Figure 4 shown, the two ends of the tension spring are respectively connected to the connecting arms 11 of the two guiding parts 1. When the two guiding driving parts 2 respectively drive the two guiding parts 1 to move to the relaxed position, the tension spring is elastically deformed due to being pulled apart by the two guiding parts 1. When the two guiding driving parts 2 are respectively separated from the corresponding guiding parts 1, the elastic tension generated by the elastic deformation of the tension spring pulls the two guiding parts 1 back to the contact position.

[0053] As Figure 1 、 Figure 2 and Figure 7 shown, each guiding driving part 2 includes a second sleeve part 21, and the second sleeve part 21 is correspondingly arranged with the first sleeve part 13 of the corresponding guiding part 1. The second sleeve part 21 is movably sleeved on the guiding column 310 on which the corresponding first sleeve part 13 is installed, so as to be used for contacting the corresponding first sleeve part 13 to drive the corresponding guiding part 1 to move.

[0054] Specifically, the slewing mechanism 20 has a moving body installed on the guiding column 310 of the carriage mechanism 30 to move along the guiding column 310 and a rotating part installed on the moving body to drive the drill pipe 210 to rotate; each guiding driving part 2 further includes a mounting plate 22. One side of the mounting plate 22 is connected to the moving body of the slewing mechanism 20 and is located on the side of the moving body close to the guiding part 1. The other side of the mounting plate 22 is used for mounting the second sleeve part 21, so that the second sleeve part 21 is fixed on the moving body of the slewing mechanism 20 through the mounting plate 22 and moves along with the moving body of the slewing mechanism 20.

[0055] As Figures 5 to 7 shown, one end of the first sleeve part 13 close to the second sleeve part 21 has a first inclined surface 131 arranged at a predetermined angle with the center line of the guiding column 310; one end of the second sleeve part 21 close to the first sleeve part 13 has a second inclined surface 211 for contacting and cooperating with the first inclined surface 131; when the guiding driving part 2 moves in the direction close to the corresponding guiding part 1, the second inclined surface 211 applies pressure to the corresponding first inclined surface 131 by contacting the corresponding first inclined surface 131, so as to drive the corresponding guiding part 1 to rotate.

[0056] As Figure 2As shown, multiple guiding parts 1 include a first guiding part 101 and a second guiding part 102 respectively arranged on opposite sides of the drill pipe 210. Multiple guiding driving parts 2 include a first guiding driving part and a second guiding driving part respectively located on opposite sides of the drill pipe 210. A second inclined surface 211 of each guiding driving part 2 contacts a part of the first inclined surface 131 of the corresponding guiding part 1 that is far from the drill pipe 210, and is spaced from a part of the first inclined surface 131 of the corresponding guiding part 1 that is close to the drill pipe 210, so as to drive a part of the first inclined surface 131 of the corresponding guiding part 1 that is close to the drill pipe 210 to rotate in a direction away from the drill pipe 210, thereby causing the guide wheels 12 of the corresponding guiding part 1 to move in a direction away from the drill pipe 210.

[0057] Preferably, a predetermined angle between the first inclined surface 131 and the axis of the guiding column 310 is an acute angle.

[0058] Optionally, the guiding part 1 includes at least one guide wheel group. The number of guide wheels 12 in each guide wheel group is one, and the center line of the guide wheel 12 is arranged parallel to a predetermined direction; or the guiding part 1 includes at least one guide wheel group. The number of guide wheels 12 in each guide wheel group is multiple, and the multiple guide wheels 12 are arranged at intervals along the moving direction of the drill pipe 210, and the center lines of all the guide wheels 12 are arranged parallel to the predetermined direction.

[0059] As Figure 3 and Figure 4 shown in the embodiment, multiple guiding parts 1 include a first guiding part 101 and a second guiding part 102. The first guiding part 101 has one guide wheel group, and the second guiding part 102 has two guide wheel groups; when both the first guiding part 101 and the second guiding part 102 are in the contact position, these three guide wheel groups are arranged at intervals around the circumference of the drill pipe 210 to jointly guide and support the drill pipe 210; wherein, the number of guide wheels 12 in each guide wheel group is at least one.

[0060] As Figures 1 to 10 shown, the present invention also provides an anchor drill, including a drill pipe 210, a support frame 10, a slewing mechanism 20 and a carriage mechanism 30. The carriage mechanism 30 is arranged on the support frame 10. The slewing mechanism 20 is arranged on the carriage mechanism 30 so as to be reciprocally movable along a predetermined direction, so as to guide the movement of the slewing mechanism 20 through the carriage mechanism 30. The drill pipe 210 is arranged on the slewing mechanism 20 to move and rotate under the drive of the slewing mechanism 20 to perform drilling work; the anchor drill further includes the above-mentioned drill pipe guiding mechanism 60. The drill pipe guiding mechanism 60 is installed on the carriage mechanism 30 to guide and support the movement of the drill pipe 210 on the slewing mechanism 20.

[0061] The bolt drill of the present invention further includes a first-stage propulsion mechanism 40 and a second-stage propulsion oil cylinder 50. Among them, the first-stage propulsion mechanism 40 is installed on the fixed plate 330 of the carriage mechanism 30 and is drivingly connected to the slewing mechanism 20 to drive the slewing mechanism 20 to reciprocate relative to the carriage mechanism 30 along a predetermined direction; the second-stage propulsion oil cylinder 50 is arranged on the support frame 10 and is drivingly connected to the carriage mechanism 30 to drive the carriage mechanism 30 to reciprocate relative to the support frame 10 along a predetermined direction.

[0062] The working process of the bolt drill of the present invention with a drill pipe guiding mechanism 60 is as follows:

[0063] (1) As Figure 1 shown, the drill pipe 210 is installed on the slewing mechanism 20, and then the slewing mechanism 20 moves to the right driven by the first-stage propulsion mechanism 40. At the same time, the slewing mechanism 20 drives the drill pipe 210 to move and drives the drill pipe 210 to rotate.

[0064] (2) When the drill pipe 210 rotates, the guide wheels 12 on each guiding part 1 that are in contact with the drill pipe 210 play a role of guiding and supporting the drill pipe 210 and start to rotate relative to the drill pipe 210, so that the drill pipe 210 can be smoothly pushed to the right with the slewing mechanism 20 to perform the drilling construction work.

[0065] (3) As Figure 2 shown, when the slewing mechanism 20 runs to the right until the second inclined surfaces 211 of the two guiding and driving parts 2 respectively come into contact with the first inclined surfaces 131 of the two guiding parts 1, the slewing mechanism 20 continues to move to the right to drive the two guiding and driving parts 2 to continue to move to the right, so that the two guiding and driving parts 2 respectively apply pressure to the first inclined surfaces 131 of the corresponding guiding parts 1 through their second inclined surfaces 211, so as to drive the corresponding guiding parts 1 to rotate from the contact position to the relaxation position, so as to avoid collision between the slewing mechanism 20 and the two guiding parts 1 when the slewing mechanism 20 moves to the right side of the carriage mechanism 30.

[0066] (4) When the first-stage propulsion mechanism 40 drives the slewing mechanism 20 to return from the right side of the carriage mechanism 30 to the left side, the second inclined surfaces 211 of the two guiding and driving parts 2 are gradually separated from the first inclined surfaces 131 of the two guiding parts 1 respectively, and the pressure applied by the two guiding and driving parts 2 to the first inclined surfaces 131 of the corresponding guiding parts 1 through their second inclined surfaces 211 gradually decreases until it disappears, so that the two guiding parts 1 return to the contact position from the relaxation position under the action of the return elastic member 3. At this time, the guide wheels 12 of each guiding part 1 resume the guiding and supporting effect on the drill pipe 210 and rotate relative to the drill pipe 210, so that the drill pipe 210 can smoothly return to the left with the slewing mechanism 20.

[0067] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0068] (1) The drill pipe guiding mechanism 60 of the present invention can effectively and reliably support and guide the drill pipe 210 of the rock bolt drill during the drilling process, avoiding the problem of inaccurate drilling hole positioning caused by the shaking of the drill pipe 210. At the same time, it reduces the time required for drilling hole positioning, improves the working efficiency of the drill pipe 210, and ensures the quality of the drilling hole.

[0069] (2) The guide wheels 12 on the guiding part 1 of the drill pipe guiding mechanism 60 of the present invention can rotate relative to the drill pipe 210 when the drill pipe 210 rotates, so as to reduce the frictional loss between the guide wheels 12 and the drill pipe 210, and extend the service life of the guide wheels 12 and the drill pipe 210.

[0070] (3) The structure of the drill pipe guiding mechanism 60 of the present invention is simple, has a small volume and flexible and reliable operation, and is suitable for working underground in coal mines.

[0071] (4) When using the rock bolt drill with the drill pipe guiding mechanism 60 of the present invention for drilling construction, only one person can complete all the work, saving the labor of one to two people.
