DETAILED DESCRIPTION

[0060] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application.

[0061] Embodiment 1: refer to Figure 1 and Figure 2, positioning assembly, relates to the technical field of drilling device, and is mainly used for avoiding deviation of a drill bit during drilling. The overall structure is constructed based on a movable base 1. First, a fixed rod 2 is fixedly installed on the top of the movable base 1, and the fixed rod 2 is perpendicular to the top surface of the movable base 1, thereby playing a supporting and guiding role. A lead screw 3 is installed on the top of the movable base 1 through a bearing or other rotating connecting structure, and the lead screw 3 can rotate on the movable base 1 about the axis of the lead screw 3. A pressing plate 4 is slidably sleeved on the outer wall of the fixed rod 2, and the pressing plate 4 is threadedly connected with the lead screw 3. When the lead screw 3 rotates, the pressing plate 4 moves up and down along the axial direction of the fixed rod 2. A drill rod 5 is rotatably arranged in the pressing plate 4, and the drill rod 5 can freely rotate relative to the pressing plate 4, thereby being used for subsequent drilling operations.

[0062] With reference to Figure 1 and Figure 2 , in order to avoid displacement of the movable base 1 during the rotating drilling process of the drill rod 5, a positioning structure is arranged in the movable base 1. The positioning structure comprises a plurality of L-shaped supports 8 fixedly installed on the top of the movable base 1, and the vertical parts of the L-shaped supports 8 are fixed on the movable base 1, and the horizontal parts extend upward. A magnetic coupler 9 is fixed on the top of one of the L-shaped supports 8, and the magnetic coupler 9 has an input shaft and an output shaft, wherein the input shaft is used for receiving external power, and the output shaft is used for outputting power.

[0063] With reference to Figures 1-3 , a first synchronous wheel 10 is fixedly installed on the input shaft of the magnetic coupler 9. A second synchronous wheel 11 is slidably connected on the outer wall of the drill rod 5 through a sliding groove and sliding block structure, and the sliding groove and sliding block structure enables the second synchronous wheel 11 to move along the axial direction of the drill rod 5, but the second synchronous wheel 11 can keep a relatively fixed rotating relationship with the drill rod 5. A synchronous belt is used to transmissionally connect the first synchronous wheel 10 and the second synchronous wheel 11, and when the drill rod 5 rotates, the synchronous belt is driven to rotate through the second synchronous wheel 11, and then the first synchronous wheel 10 is driven to rotate, so that the input shaft of the magnetic coupler 9 rotates.

[0064] With reference to Figure 1 and Figure 2 , a support rod 6 is fixedly installed on one side of the fixed rod 2, and a limiting ring 7 is fixedly installed on one end of the support rod 6. The limiting ring 7 is sleeved on the outer wall of the drill rod 5, and the inner diameter of the limiting ring 7 is slightly larger than the outer diameter of the drill rod 5, thereby being used for constraining the rotating drill rod 5 and avoiding shaking of the drill rod 5 during the rotating process. The second synchronous wheel 11 rotates on the top of the limiting ring 7, thereby further ensuring stable rotation of the second synchronous wheel 11.

[0065] With reference to Figures 1-3The bottom of one side of each of the plurality of L-shaped supports 8 is rotatably connected to a transmission rod 13 through a bearing, the transmission rod 13 can rotate around its own axis, and a plurality of threaded rods 12 are screwed through the movable base 1. The transmission rod 13 slides into the adjacent threaded rod 12, a through hole matched with the transmission rod 13 is arranged at the top end of the threaded rod 12, and the transmission rod 13 can slide in the through hole. A third synchronous wheel 14 is fixedly sleeved on the outer wall of the transmission rod 13, and the plurality of third synchronous wheels 14 are connected through a synchronous belt. The output shaft of the magnetic coupler 9 is fixedly connected to the top end of the adjacent transmission rod 13, and when the output shaft of the magnetic coupler 9 rotates, the transmission rod 13 can be driven to rotate. Since the plurality of third synchronous wheels 14 are connected through the synchronous belt, the plurality of transmission rods 13 rotate synchronously.

[0066] Reference Figures 1-3 The threaded rod 12 is screwed through the movable base 1, and a drill bit is arranged at the bottom end of the threaded rod 12, so that the threaded rod 12 can be inserted into the mine. A positioning ring is fixedly arranged at the position of the outer wall of the threaded rod 12 at the top end, and the outer diameter of the positioning ring is greater than the inner diameter of the through hole of the movable base 1 for the threaded rod 12 to pass through, so as to limit the threaded rod 12 and prevent the threaded rod 12 from being completely separated from the movable base 1.

[0067] When drilling is needed, the drill rod 5 starts to rotate. When the drill rod 5 rotates, power is transmitted to the magnetic coupler 9 through the transmission of the second synchronous wheel 11, the first synchronous wheel 10 and the synchronous belt, so that the input shaft of the magnetic coupler 9 rotates. The output shaft of the magnetic coupler 9 drives the adjacent transmission rod 13 to rotate, and since the plurality of transmission rods 13 are connected through the third synchronous wheel 14 and the synchronous belt, the plurality of transmission rods 13 rotate synchronously. When the transmission rod 13 rotates, the threaded rod 12 is driven to rotate synchronously. Since the threaded rod 12 is screwed with the movable base 1, when the mine drill bit contacts the ore, the threaded rod 12 will first be inserted into the mine, and through the friction between the threaded rod 12 and the mine and the self-locking property of the threaded connection, the movable base 1 can be positioned as a whole, so that the displacement of the movable base 1 during the rotation of the drill rod 5 for drilling is avoided, thereby ensuring the accuracy and stability of drilling and improving the drilling quality and efficiency.

The output shaft and the input shaft of the gearbox 18 are both fixedly connected with a third bevel gear 19, the second bevel gear 17 and the fourth bevel gear 20 are respectively engaged with the adjacent third bevel gear 19, and the gearbox 18 is used to adjust the speed ratio of the drill rod 5 and the lead screw 3, so that the drill rod 5 can move downward for drilling when rotating.

[0070] Specifically, the driving motor 15 drives the drill rod 5 and the mine drill bit 25 to rotate through the cooperation of the first bevel gear 16 and the second bevel gear 17, the drill rod 5 transmits power to the gearbox 18 through the cooperation of the second bevel gear 17 and one of the third bevel gears 19, the gearbox 18 adjusts the speed ratio of the output shaft and the input shaft, the lead screw 3 is driven to rotate through the cooperation of the fourth bevel gear 20 and the other third bevel gear 19, and then the pressing plate 4 drives the drill rod 5 to move downward synchronously when the drill rod 5 rotates, thereby performing drilling operation.

[0071] Referring to Figure 7 , in order to replace the mine drill bit 25 when the temperature of the mine drill bit 25 is too high, a dismounting structure is arranged between the drill rod 5 and the mine drill bit 25. The dismounting structure comprises a mounting groove 26 arranged at the bottom end of the drill rod 5 and a connecting seat 27 fixed at the top end of the mine drill bit 25, and the connecting seat 27 is insertedly connected with the mounting groove 26.

The lifting of the first sliding plate 30 can drive the trapezoidal clamping plate 31 to move through the connecting rod 32, and the insertion connection of the trapezoidal clamping plate 31 and the clamping groove 33 is completed.

[0073] Specifically, when the mine drill bit 25 needs to be replaced, the drill rod 5 is moved upward, the drainage inclined hole 24 is moved to the position of the second synchronous wheel 11, at this time the drainage inclined hole 24 is blocked, and the water pressure in the cooling channel 23 can drive the sliding rod 35 to press the first sliding plate 30, the first sliding plate 30 drives the trapezoidal clamping plate 31 to move to the middle through the connecting rod 32, and the trapezoidal clamping plate 31 is disengaged from the clamping groove 33, thereby automatically completing the disassembly of the mine drill bit 25.

[0074] With reference to Figure 6 and Figure 7 , in order to automatically disengage the trapezoidal clamping plate 31 from the clamping groove 33, a water injection structure is arranged in the drill rod 5, and the water injection structure can also be used for cooling the drill rod 5 in the drill hole. The water injection structure includes a cooling channel 23 and a drainage inclined hole 24 arranged in the drill rod 5.

[0075] The type of the drainage inclined hole 24 can be:

[0076] 1. Venturi inclined hole: the inlet section diameter is 4 mm, the throat is reduced to 2 mm, and the outlet is expanded to 5 mm to form a high-speed jet;

Meanwhile, the receiving structure can accurately receive the disassembled mine drill bit 25 and install the corresponding mine drill bit 25 on the drill rod 5, thereby further improving the operation convenience.

[0080] With reference to Figure 7 and Figure 8 , the disassembly structure includes an axially extending cooling channel 23 arranged in the drill rod 5, and the bottom end of the cooling channel 23 is in communication with the mounting groove 26. A fixed frame structure of a metal frame is fixedly installed in the cooling channel 23, a sliding rod 35 vertically penetrates the center of the fixed frame 34, and the sliding rod 35 can reciprocate up and down along the fixed frame 34. The top end of the sliding rod 35 is fixedly connected with a second sliding plate 36, the second sliding plate 36 is in sealing sliding fit with the inner wall of the cooling channel 23, and a second spring 37 is arranged on the outer wall of the sliding rod 35. The two ends of the spring are respectively in abutment with the second sliding plate 36 and the fixed frame 34 through spring seats.

[0081] When the electromagnetic valve 22 is opened, the external water source is injected into the cooling channel 23 through the inlet pipe 21, and the water flow pressure drives the second sliding plate 36 to move downward against the elastic force of the second spring 37. The sliding rod 35 moves downward synchronously, and the lower end extends into the trapezoidal groove of the first sliding plate 30, driving the first sliding plate 30 to slide downward along the inner wall of the mounting groove 26. The first sliding plate 30 pulls the trapezoidal clamping plate 31 through the connecting rod 32, so that the trapezoidal clamping plate 31 is withdrawn from the clamping groove 33 of the connecting seat 27, and the clamping and fixing of the drill pipe 5 and the mine drill bit 25 are released.

[0082] Referring to Figure 7 , a plurality of drainage inclined holes 24 with a diameter of 3-5 mm are uniformly arranged on the side wall of the cooling channel 23, and the axes of the holes are inclined downward at an angle of 45° with the axis of the drill pipe 5. During drilling, high-pressure water flow is obliquely sprayed from the drainage inclined holes 24, which not only cools the mine drill bit 25, but also uses the reaction force of the water flow to remove the sludge generated during drilling from around the drill bit, preventing the sludge from entering the drainage inclined holes and causing blockage.

A first magnet 41 is embedded at the bottom of each support arm 39, and a second magnet 42 is fixed by bolts at the corresponding position of the movable base 1. Both magnets are made of sintered samarium-cobalt material and are treated by surface nickel plating. The magnetic attraction force ensures that the support arm 39 is horizontally positioned in the non-working state, and the rotating ring 38 rotates on the outer wall of the lead screw 3.

[0084] A tapered hole 40 is formed in the inner side of each support arm 39, the axis of the tapered hole coincides with the axis of the drill pipe 5, and the taper is designed as 1:20 to adapt to different specifications of drill bits. An arc-shaped connecting plate 43 is welded between adjacent support arms 39, and a third magnet 44 is installed at the bottom of the arc-shaped connecting plate 43 to form a secondary magnetic attraction force with the second magnet 42. When the support arm 39 is turned to the working position under the action of the magnetic attraction force, the third magnet 44 is attracted to the second magnet 42, so that the arc-shaped connecting plate 43 is kept in an inclined state at an angle of 30° with the axis of the drill pipe 5, avoiding interference between the support arm 39 and the drilling operation.

[0085] Example 2: Referring to Figures 10-12On the basis of improving embodiment 1, a lifting groove 45 is opened in the mobile base 1, and a push plate 46 that can slide up and down is installed in the groove. The positioning ring on the outer wall of the threaded rod 12 is in contact with the upper surface of the push plate 46. When the threaded rod 12 is inserted into the mine positioning, the push plate 46 is pressed down, and the rubber ring 47 at the bottom of the push plate 46 tightly fits the mine wall. The rubber ring 47 is made of high-temperature-resistant fluorine rubber, and the inner diameter is 2mm smaller than the outer diameter of the drill rod 5 to ensure sealing. A plurality of third springs 48 are installed between the bottom of the push plate 46 and the inner wall of the bottom of the lifting groove 45 through the spring seat, which is used to drive the push plate 46 to move upwards.

[0086] Reference Figures 10-12 A liquid inlet groove 49 is provided in the mobile base 1, and a moving plate 52 with a one-way valve hole is sealingly and slidingly installed in the groove. The bottom end of the lead screw 3 extends to the liquid inlet groove 49 and is fixed with a rotating disc 50. The edge of the disc is connected with a rotating rod 51 through a pin shaft, and the other end of the rod is hinged with the moving plate 52. When the lead screw 3 drives the rotating disc 50 to rotate, the rotating rod 51 drives the moving plate 52 to make reciprocating linear motion in the liquid inlet groove 49, and the one-way valve ensures that the water flow only flows in the direction of the liquid outlet hole 53. The liquid outlet hole 53 is provided at the top of the mobile base 1, and its position corresponds to the tapered hole 40 of the support arm 39. When the second magnet 42 is aligned with the third magnet 44, the liquid outlet hole 53 and the tapered hole 40 form a straight-through flow channel. The cooling water overflowing from the drainage inclined hole 24 during drilling is intercepted by the rubber ring 47, collected by the liquid inlet groove 49, and then pumped to the liquid outlet hole 53 by the moving plate 52, realizing continuous spray cooling of the disassembled mine drill bit 25.

[0087] Reference Figures 10-12 A ring-shaped retaining ring 54 is welded at the top of the mobile base 1, and the inner diameter of the retaining ring is 5mm larger than the radius of rotation of the support arm 39, and the outer edge height exceeds the upper end of the liquid outlet hole 53 by 2mm. When the support arm 39 is in the working position, the upper surface of the retaining ring 54 is in contact with the lower surface of the support arm 39, forming an annular water storage space. When the spray system is started, the retaining ring 54 effectively prevents the water flow from spreading along the surface of the mobile base 1, and forces the water flow to flow through the tapered hole 40 to the mine drill bit 25, improving the cooling efficiency.

[0088] The use method of the energy-saving mine blasting construction drilling device comprises the following steps:

[0089] S1, the position to be drilled is flattened to ensure the stability of the mobile base 1 in the later period, and then the mobile base 1 is moved to the position to be drilled, and the position to be drilled is located below the mine drill bit 25. The mobile base 1 needs to be positioned before the mine drill bit 25 drills a hole to avoid displacement during the later drilling process. Specifically, the driving motor 15 drives the drill rod 5 and the mine drill bit 25 to rotate through the cooperation of the first bevel gear 16 and the second bevel gear 17. The drill rod 5 transmits power to the gearbox 18 through the cooperation of the second bevel gear 17 and one of the third bevel gears 19. The gearbox 18 adjusts the speed ratio of the output shaft and the input shaft. The fourth bevel gear 20 cooperates with the other third bevel gear 19 to drive the lead screw 3 to rotate. When the drill rod 5 rotates, the pressure plate 4 drives the drill rod 5 to move downward synchronously. The drill rod 5 transmits power to the magnetic coupling 9 through the transmission of the second synchronous pulley 11, the first synchronous pulley 10 and the synchronous belt. The output shaft of the magnetic coupling 9 drives the transmission rod 13 to rotate. The third synchronous pulley 14 and the transmission belt drive the multiple transmission rods 13 to rotate synchronously. The multiple transmission rods 13 drive the multiple threaded rods 12 to rotate synchronously. The threaded rod 12 is threadedly connected with the mobile base 1. Therefore, when the mine drill bit 25 contacts the ore, the threaded rod 12 is inserted into the mine first, thereby positioning the mobile base 1 as a whole.

[0090] S2, when the mine drill bit 25 drills a hole, open the electromagnetic valve 22. The water source outside is injected into the cooling channel 23 through the water pump, and is discharged to the outside through the drainage inclined hole 24. When the mine drill bit 25 drills a hole, the water discharged from the drainage inclined hole 24 can cool the mine drill bit 25 to avoid the wear of the mine drill bit 25 caused by high temperature.

[0091] S3, when the mine drill bit 25 is used for a long time and the temperature cannot be effectively reduced, the mine drill bit 25 is moved upward to reset. When the drainage inclined hole 24 moves to the position of the second synchronous pulley 11, manually rotate the support arm 39 to make the conical hole 40 located above the mine drill bit 25. At this time, water is continuously injected into the cooling channel 23 through the opening of the electromagnetic valve 22. Since the drainage inclined hole 24 is blocked by the second synchronous pulley 11, the second sliding plate 36 pushes the sliding rod 35 downward under the action of water pressure and synchronously drives the first sliding plate 30 to move downward. The first sliding plate 30 pulls the trapezoidal clamping plate 31 out of the clamping groove 33 through the connecting rod 32, thereby releasing the clamping connection between the drill rod 5 and the connecting seat 27, and completing the disassembly of the mine drill bit 25. The mine drill bit 25 just falls into the conical hole 40, which is convenient for cooling the mine drill bit 25 for later use.

[0092] S4, when the mine drill bit 25 needs to be reinstalled, the support arm 39 is actuated to move the cooled new mine drill bit 25 to the lower side of the drill rod 5, then the drill rod 5 is rotated downward until the connecting seat 27 is inserted into the installation slot 26, the trapezoidal clamping plate 31 is pressed against the inner wall of the installation slot 26 under the cooperation of the first spring 29 and the connecting rod 32, and the friction between the inner wall of the installation slot 26 and one end of the trapezoidal clamping plate 31 installs the mine drill bit 25 at the bottom end of the drill rod 5, after that, the drill rod 5 is moved upward to reset, the mine drill bit 25 is separated from the conical hole 40, then the support arm 39 is rotated to avoid the support arm 39 from blocking the drilling of the drill rod 5, and in subsequent drilling, the friction between the mine drill bit 25 and the mine makes the mine drill bit 25 stationary relative to the drill rod 5 until the trapezoidal clamping plate 31 is aligned with and inserted into the clamping groove 33, so that the drill rod 5 can drive the mine drill bit 25 to drill;

[0093] S5, in order to ensure that the conical hole 40 can be accurately aligned with the drill rod 5, when the first magnet 41 moves to the second magnet 42, the magnetic attraction between the second magnet 42 and the first magnet 41 can position the support arm 39, so as to ensure that the collection and installation of the mine drill bit 25 can be accurately completed, and the magnetic attraction between the third magnet 44 and the second magnet 42 can ensure that the support arm 39 is misaligned with the drill rod 5, so as to avoid blocking the drill rod 5;

[0094] S6, in addition, when the threaded rod 12 is inserted into the mine to position the movable base 1, the positioning ring on the outer wall of the threaded rod 12 pushes the push plate 46 and the rubber ring 47 downward, so that the rubber ring 47 tightly contacts the mine, and in the later drilling of the drill rod 5 in cooperation with the mine drill bit 25, the rubber ring 47 can block the water sprayed from the drainage inclined hole 24, so as to avoid water overflow, and the water is stored in the rubber ring 47 and enters the liquid inlet groove 49, the water in the liquid inlet groove 49 moves to the position close to the liquid outlet hole 53 in the liquid inlet groove 49 through the one-way valve in the moving plate 52, and when the lead screw 3 drives the rotating disc 50 to rotate, the rotating disc 50 drives the moving plate 52 to reciprocatingly move linearly through the rotating rod 51, so that the water in the liquid inlet groove 49 can be sprayed to the previously removed mine drill bit 25 through the liquid outlet hole 53, for continuously water cooling the mine drill bit 25, so as to facilitate the later use, and the water can be reused in this process, so as to reduce the loss of water resources.
