[0048] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work fall within the scope of protection of the present invention.

[0049] Embodiment 1:

[0050] The drill for coal mine roadway, as Figure 1 shown, includes a support plate 1, a driven device 2, a driving device 3, a horizontal moving device 4, a vertical moving device 5, a drill pipe device 6, a spraying device 7, a regulation device 8, and a housing 9.

[0051] The bottom surface of the support plate 1 is connected to the driving device 3 and the driven device 2, and the driving device 3 is used to drive the entire drill to move. The right side of the support plate 1 is connected to a rectangular housing 9, and the interior of the housing 9 is a cavity. The housing 9 is used to install the horizontal moving device 4, the vertical moving device 5, and the spraying device 7.

[0052] Since the regulation device 8 needs to pass through the housing 9 to drive the driving device 3 to rotate in order to realize the movement of the drill, a long strip-shaped notch is opened on the upper surface of the housing 9.

[0053] A chute is also provided on the housing 9, and the bottom of the vertical moving device 5 is slidably connected to the chute of the housing 9, as Figure 1As shown, the chute is parallel to the long strip-shaped notch. The sliding connection method can also be in the form of a slide rail or a roller, as long as it can enable the vertical moving device 5 to move horizontally. The moving track of the vertical moving device 5 can be parallel to the horizontal moving device 4, so as to realize the synchronous horizontal movement of the horizontal moving device 4 and the vertical moving device 5.

[0054] Specifically, as Figure 2 , Figure 3 , Figure 4 shown, the driving device 3 includes a rotating rod 31, a clamping block 32, a wheel 33, a one-way steering bearing 34, a regulating plate 35, an elastic telescopic rod 36, and a rotating bearing 37;

[0055] Both ends of the rotating rod 31 are connected to the inner ring of the rotating bearing 37, and the outer ring of the rotating bearing 37 is connected to the bottom surface of the support plate 1 through a connecting rod. Both ends of the rotating rod 31 are respectively fixedly connected with the wheels 33. Two clamping blocks 32 are fixedly connected to both ends of the rotating rod 31 and are located inside the wheels 33. As Figure 3 , Figure 4 shown, the clamping block 32 is of a circular plate structure and includes a plurality of card slots along the circumference, and the card slots can be clamped with the first clamping plates 351 at both ends of the regulating plate 35.

[0056] As Figure 5 shown, there are two one-way steering bearings 34, and the two one-way steering bearings 34 are connected to the middle of the rotating rod 31. As Figure 5 shown, each one-way steering bearing 34 includes a first inner ring 341, a first outer ring 342, and a ratchet structure 343. The first inner ring 341 is fixedly connected to the outer surface of the rotating rod 31, and welding can be used. The first outer ring 342 is rotatably connected to the outside of the first inner ring 341. A rectangular notch is opened at the outer edge of the first inner ring 341, and the ratchet structure 343 is connected in the rectangular notch; a plurality of tooth angles are opened along the circumferential direction on the outer ring of the first outer ring 342; the tooth angles can be meshed with the rack bar 82 at the bottom of the regulating device 8.

[0057] The ratchet structure 343 is arranged on the first inner ring 341 and is located between the first inner ring 341 and the first outer ring 342. Under the action of the ratchet structure 343, only when the rotation direction of the first outer ring 342 can make the ratchet structure 343 engage with the first outer ring 342, the first outer ring 342 can drive the first inner ring 341 to rotate. This makes it so that during the up-and-down reciprocating movement of the rack bar 82, only a specific rotation direction of the first outer ring 342 can drive the first inner ring 341 to rotate in one direction during the process of driving the first outer ring 342 to rotate. The rotation direction of the rotating rod 31 is also determined by the one-way rotation direction of the first inner ring 341, and the moving direction of the wheel 33 is also determined accordingly.

[0058] The ratchet structure 343 includes a ratchet clip and a first spring. One end of the ratchet clip is rotatably connected to the side wall of the rectangular notch of the first inner ring 341. The bottom of the first spring is connected to the bottom surface of the rectangular notch. The top of the first spring is connected to the ratchet clip. Under the elastic force of the first spring, the end of the ratchet clip is lifted and clipped into the semicircular clip groove on the inner ring of the first outer ring 342. Figure 4 As shown, when the first outer ring 342 rotates clockwise, the inner ring of the first outer ring 342 can always press the ratchet strip, and the ratchet strip cannot be stuck in the semicircular groove of the first outer ring 342, and the first outer ring 342 and the first inner ring 341 have no linkage relationship; when the first outer ring 342 rotates counterclockwise, since the end of the ratchet strip is tilted, it can be stuck in the semicircular groove. At this time, the rotation of the first outer ring 342 can drive the rotation of the first inner ring 341.

[0059] In this embodiment, the installation directions of the ratchet clips in the two one-way steering bearings 34 are opposite, and correspondingly, the first outer ring 342 of the two one-way steering bearings 34 drives the first inner ring 341 to rotate in opposite directions. For example, if the first outer ring 342 of a one-way steering bearing 34 can only drive the first inner ring 341 to rotate in a clockwise direction, then the first outer ring 342 of the other one-way steering bearing 34 can only drive the first inner ring 341 to rotate in a counterclockwise direction. This allows the two one-way steering bearings 34 to drive the rotating rod 31 connected thereto to rotate in different directions, and finally causes the wheel 33 to rotate and move in opposite directions, thereby achieving forward and backward movement.

[0060] In actual use, such as Figure 2As shown, the rack bar 82 can achieve the forward and backward movement of the wheel 33 when meshing with the first outer rings 342 of the two one-way steering bearings 34 respectively. For example, when the rack bar 82 moves downward, it can only drive the right one-way steering bearing 34 to achieve the linkage between the first outer ring 342 and the first inner ring 341. At this time, the first outer ring 342 and the first inner ring 341 of the left one-way steering bearing 34 cannot form a linkage. When the rack bar 82 moves upward, it can only drive the left one-way steering bearing 34 to achieve the linkage between the first outer ring 342 and the first inner ring 341. At this time, the first outer ring 342 and the first inner ring 341 of the right one-way steering bearing 34 cannot form a linkage. Driven by the second motor 51, the up and down movement of the rack bar 82 can drive the two first inner rings 341 to rotate in different directions respectively to control the different rotation directions of the rotating rod 31. Finally, the two one-way steering bearings 34 can control the forward and backward movement of the wheel 33 respectively. When it is necessary to switch between forward and backward, the first motor 43 drives the belt transmission structure 41 to drive the block 44 to move. The block 44 can move the rack bar 82 horizontally, moving the rack bar 82 from the left one-way steering bearing 34 to the right one-way steering bearing 34, or from the right one-way steering bearing 34 to the left one-way steering bearing 34. It should be noted that at this time, the electric push rod 54 extends or retracts synchronously, moving synchronously with the block 44, so as to keep the rack bar 82 as vertical as possible and be able to mesh well with the one-way steering bearing 34.

[0061] As Figure 4 As shown, the middle part of the regulation plate 35 is a rectangular plate. Long strip-shaped rods are connected to both sides of the rectangular plate. The two ends of the long strip-shaped rods are horizontally connected to the first clamping plates 351. One side of the rectangular plate is connected to the elastic telescopic rod 36, and the other end of the elastic telescopic rod 36 is connected to the inner wall of the housing 9. The elastic telescopic rod 36 moves the regulation plate 35 towards the direction of the one-way steering bearing 34, so that the first clamping plate 351 is stuck in the card slot on the clamping block 32, so as to keep the rotating rod 31 from rotating any more and the vehicle body of the equipment is stationary, ensuring the stability of the overall position of the drill rod device 6 during operation. When the vehicle body needs to move, the wedge block at the bottom of the rack bar 82 will be inserted between the regulation plate 35 and the one-way steering bearing 34, compressing the elastic telescopic rod 36, so that the first clamping plate 351 is separated from the clamping block 32.

[0062] The driven device 2 has no power and only assists the movement of the whole equipment when the driving device 3 is moving. The existing technology can be adopted.

[0063] As Figure 1 、 Figure 6As shown, the horizontal movement device 4 includes a belt transmission structure 41, a mounting bracket 42, a first motor 43, and a dial block 44; the bottom of the mounting bracket 42 is connected to the housing 9, the first motor 43 is mounted on the mounting bracket 42, the pulley of the belt transmission structure 41 is also fixed on the housing 9, and the output end of the first motor 43 is connected to the pulley of the belt transmission structure 41; the dial block 44 is fixedly connected to the belt of the belt transmission structure 41. The belt transmission structure 41 is a belt transmission structure in the prior art. Driven by the first motor 43, the dial block 44 moves together with the belt, and can move the regulation device 8 horizontally.

[0064] One side of the dial block 44 includes a semi-circular groove, and the first rod 81 of the regulation device 8 is a cylindrical rod, and the cylindrical rod can be stuck in the semi-circular groove. At the same time, the first rod 81 can also slide along the height direction of the semi-circular groove.

[0065] When the dial block 44 can contact the regulation device 8, the dial block 44 can move the regulation device 8 horizontally; if the dial block 44 does not move, the drill rod device 6 and the regulation device 8 can be moved up and down by the vertical movement device 5.

[0066] The vertical movement device 5 includes a second motor 51, a screw rod 52, an annular block 53, and an electric push rod 54; the bottom of the second motor 51 is connected to a mounting seat, the bottom of the mounting seat is slidably connected to the top surface of the housing 9, the screw rod 52 is connected to the output end of the second motor 51, the screw rod 52 is arranged vertically, the screw rod 52 is threadedly connected to the annular block 53, and one side of the annular block 53 is rotatably connected to the drill rod device 6. The operation of the second motor 51 can drive the screw rod 52 to rotate, and the annular block 53 can drive the drill rod device 6 to move up and down or rotate. The fixed end of the electric push rod 54 can be fixed on the housing 9, and the telescopic end is connected to the side surface of the mounting seat to drive the mounting seat to slide on the top surface of the housing 9.

[0067] The drill rod device 6 includes a mounting plate 61, a driving mechanism 62, and a drill rod body 63; the back of the mounting plate 61 is connected to the annular block 53, a slide rail is provided on the front side surface of the mounting plate 61, the driving mechanism 62 is connected to the slide rail and can move vertically, and the output end of the driving mechanism 62 is connected to the drill rod body 63.

[0068] As Figure 6 、 Figure 7As shown in the figure, the control device 8 includes a first rod 81 and a rack rod 82; the top end of the first rod 81 is ball-jointed to the bottom of the drill rod device 6, and the rack rod 82 is connected to the bottom of the first rod 81; one side of the rack rod 82 includes a plurality of teeth that can mesh with the one-way steering bearing 34, and a part of the other side of the rack rod 82 is cut off to form a wedge block, which is used to insert between the control plate 35 and the one-way steering bearing 34 to compress the elastic telescopic rod 36, so that the first clamping plate 351 is disengaged from the clamping block 32. The first rod 81 has a certain elasticity and can adapt to partial bending.

[0069] In this embodiment, the first motor 43 and the second motor 51 are not limited to the mechanism and model of the motor, as long as they can achieve driving.

[0070] The working process of this embodiment:

[0071] When the entire device needs to move forward to the construction site, the toggle block 44 is stuck with the first rod 81, and the first motor 43 drives the belt transmission structure 41 to horizontally move the rack rod 82. The wedge block on the rack rod 82 at the lower end of the first rod 81 will first collide with the rectangular block of the control plate 35 and, by virtue of its own inclined surface characteristics, cause the control plate 35 to move towards the direction of compressing the elastic telescopic rod 36. This makes the first clamping plate 351 provided on the control plate 35 also move towards the elastic telescopic rod 36 and disengage from the card slot on the clamping block 32, and the wheel 33 is then released from the restriction; the entire rack rod 82 continues to move downward and meshes with the one-way steering bearing 34 that controls the forward movement of the device. The second motor 51 of the vertical moving device 5 rotates forward, and the screw rod 52 rotates. At this time, since the toggle block 44 is stuck with the first rod 81, the entire drill rod device 6 can only move up and down. The drill rod device 6 drives the rack rod 82 of the control device 8 to move downward, and the first outer ring 342 of the one-way steering bearing 34 drives the first inner ring 341 to rotate to achieve forward movement. When the stroke of the rack rod 82 ends, the second motor 51 rotates in reverse, and the rack rod 82 moves upward. At this time, the first outer ring 342 of the one-way steering bearing 34 is disengaged from the first inner ring 341, and the device stops moving forward. When the rack rod 82 moves upward to the upper limit position, the second motor 51 rotates forward and continues to drive the rack rod 82 to move downward, and again drives the first outer ring 342 of the one-way steering bearing 34 to drive the first inner ring 341 to rotate to achieve forward movement; repeat the above actions until it moves to the preset location. If it needs to move backward, the first motor 43 drives the belt transmission structure 41 to mesh the rack rod 82 with the one-way steering bearing 34 that controls the backward movement of the device (in this process, the electric push rod 54 also moves in the same direction in cooperation with the movement of the belt transmission structure 41 to keep the first rod 81 in the vertical direction). Refer to the method of the second motor 51 above.

[0072] When it is necessary to adjust the horizontal movement of the drill pipe body 63, the dial block 44 is stuck with the first rod 81, and the first motor 43 drives the belt transmission structure 41 to move. The belt transmission structure 41 drives the first rod 81 to move horizontally. At this time, since the entire drill pipe device 6 is connected to the first rod 81, the drill pipe device 6 will also move horizontally accordingly. At this time, the vertical movement device 5 is also driven by the electric push rod 54 to move horizontally along the bottom slide rail to keep the first rod 81 in the vertical direction.

[0073] When it is necessary to adjust the vertical movement of the drill pipe body 63, on the one hand, the position of the driving mechanism 62 on the mounting plate 61 can be moved independently, or the second motor 51 can be actuated to drive the entire drill pipe device 6 to move up and down; the second motor 51 and the driving mechanism 62 can also act simultaneously.

[0074] If it is necessary to adjust the rotation of the drill pipe body 63, the vertical movement device 5 and the drill pipe device 6 can be kept stationary. The operator drives the belt transmission structure 41 to rotate through the first motor 43 to drive the dial block 44 to move. The movement of the dial block 44 drives the first rod 81 to move. Since the top end of the first rod 81 is ball-jointed with the bottom of the mounting plate 61, and the mounting plate 61 is rotatably connected to the annular block 53, an angle is formed between the first rod 81 and the mounting plate 61, so as to adjust the orientation of the mounting plate 61, and further control the orientation of the drill pipe body 63.

[0075] In this embodiment, with the cooperation of the first motor 43, the second motor 51, and the driving mechanism 62, the horizontal movement, vertical movement, and steering of the drill pipe body 63 can be changed quickly and effectively, and the adjustment process can be automatically controlled through existing control methods, with strong adaptability and high flexibility; at the same time, under the combined drive of the above-mentioned first motor 43 and second motor 51, the rack rod 82 can indirectly drive the wheel 33 to rotate to control the overall horizontal position of the device. The entire process does not require adding a new power device, avoiding the problem that in order to enable the drill rig to work at different positions, multiple drive components are often required to work together, further increasing the implementation cost; compared with the traditional adjustment method, the operation direction of the drill pipe is more comprehensive, the adjustment direction is faster, and the functionality is also greatly enhanced, and the cost is effectively reduced.

[0076] Embodiment 2:

[0077] As Figure 7 shown, on the basis of the above Embodiment 1, the drill rig for coal mine roadway also includes a spray device 7.

[0078] The spraying device 7 includes a first shower head 71 and a water tank 72. The water tank 72 is connected to the upper wall surface of the housing 9. After the air blower cylinder on the side of the water tank 72 is squeezed, it can absorb external air into the interior to increase the internal air pressure, so that the water in the water tank 72 is sprayed out from the first shower head 71. In a specific implementation, when the water tank 72 is squeezed once, a large air pressure difference can be formed inside the first shower head 71, which enables the first shower head 71 to spray water mist into the surrounding environment for a long time under a single squeeze.

[0079] In this embodiment, the front end of the shifting block 44 includes a cylindrical protrusion 441. The protruding degree of the cylindrical protrusion 441 is such that it can move horizontally to contact the spraying device 7 and can collide with the air blower cylinder of the water tank 72.

[0080] By driving the rotation of the belt transmission structure 41 by the first motor 43 to drive the movement of the shifting block 44, the movement of the shifting block 44 can drive the cylindrical protrusion 441 to collide with the water tank 72. After the water tank 72 is squeezed, it can absorb external air into the interior to increase the internal air pressure, so that the water in the water tank 72 is sprayed out through the first shower head 71. Under the action of the water mist, the dust pollution caused by the operation of the drill rod can be effectively reduced.

[0081] Embodiment Three:

[0083] The interior of the shifting block 44 is a cavity for accommodating the water diverted from the water tank 72. The water tank 72 and the shifting block 44 are connected by a hose 74, and the second shower head 73 is connected to the interior of the shifting block 44, and its function is the same as that of the first shower head 71.

[0084] The water tank 72 is arranged on the upper wall surface of the housing 9 through a connecting rod, and the interior thereof contains water for reducing the intrusion of flying dust;

[0085] Working process: When the entire device moves to the working area, the collision between the cylindrical protrusion 441 and the air blowing cylinder on the side of the water tank 72 can divert a part of the internal water flow through the hose 74 into the shifting block 44, and the other part is released through the second shower head 73; achieving the effect of reducing flying dust.

[0086] It should be noted that: Whether it is the first shower head 71 or the second shower head 73, it is not limited to the number of nozzles thereon. It is preferred that the nozzles are evenly distributed, and the number of shower heads can also be increased according to needs.

[0087] Embodiment Four:

[0088] On the basis of the above Embodiment Three, as Figure 7As shown, the top end of the shifting block 44 is connected to the vertical air cylinder 442. The collision block 83 is arranged at the top end of the first rod 81, and the collision block 83 is rotatably connected to the mounting plate 61 through a ball bearing.

[0089] During the process of the mounting plate 61 changing height and during the process of the mounting plate 61 driving the driving device 3 to move in the working area, the collision block 83 can be driven to collide with the vertical air cylinder 442, so that the water in the shifting block 44 is released through the second shower head 73 to achieve the effect of reducing flying dust.

[0090] Embodiment 4:

[0091] As Figure 8 shown, on the basis of the above Embodiment 1 or Embodiment 2, the horizontal moving device 4 further includes a guide rod 45. Both ends of the guide rod 45 can be connected to the side wall inside the housing 9 by means such as bolts and welding. The guide rod 45 is parallel to the belt transmission structure 41 and is located below the belt transmission structure 41. A through hole is formed in the lower part of the shifting block 44 in the horizontal direction, and the guide rod 45 passes through the through hole. The shifting block 44 is slidably connected to the guide rod 45.

[0092] The guide rod 45 plays a role of guiding and limiting, and can enable the shifting block 44 to move stably in the horizontal direction.

[0093] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
