[0002] A cut-slot raise drill is a device specifically used for excavating raises (shafts) in underground mines and tunnel projects. The drill gradually expands the shaft diameter by cutting slots, eventually forming a complete raise. A raise drill usually consists of a drill, a cutting head, a guide system, a propulsion system, a support system, a hydraulic system, an electrical system, and a cooling system. During the drilling process, in order to reduce the difficulty of drilling and slag removal, a water injection system is usually added to inject water on the drilling path.

[0046] like Figures 1 to 4 As shown, the present application provides a power system of a cutting slot skydrilling machine, including a power box 1, a stationary sleeve 2, a driver 3, a moving pipe 4, a first sealing assembly 5 and a second sealing assembly 6. The stationary sleeve 2 includes a sleeve 21 and a water inlet pipe 22, the sleeve 21 is fixedly mounted on the power box 1 and is arranged to penetrate along the axial direction, and the water inlet pipe 22 is connected to the sleeve 21 and communicated with the sleeve 21. The driver 3 is mounted on the end of the sleeve 21 away from the power box 1. The moving pipe 4 is rotatably mounted in the sleeve 21, and rotates around the axial direction under the drive of the driver 3, and is communicated with the sleeve 21. The first sealing assembly 5 is mounted on the end of the sleeve 21 close to the power box 1, and is configured to block the gap between the moving pipe 4 and the end of the sleeve 21 close to the power box 1. The second sealing assembly 6 is mounted on the end of the sleeve 21 close to the driver 3, and is configured to block the gap between the moving pipe 4 and the end of the sleeve 21 close to the driver 3.

[0047] It should be noted that the axial direction above and below refers to the bidirectional direction of the central axis defined by the structure of the sleeve 21 itself. Figure 2 The X-axis shown in .

[0048] The working principle of this embodiment is as follows: when the device is used, the moving tube 4 rotates around the axial direction under the drive of the driver 3. Under the action of the moving tube 4, power can be transmitted to the power box 1, and the power box 1 can drive the drilling tool 7 to rotate. At the same time, the external water source enters the sleeve 21 through the water inlet pipe 22. After the water source enters the sleeve 21, it flows through the sleeve 21 and the moving tube 4 in sequence, and is finally transmitted to the drilling tool 7, and is transmitted to the front end of the drilling path through the drilling tool 7.

[0049] The power system of the cutting groove skydrill provided by the present application, in which the driver 3 is used to replace the hollow driver 3, is helpful to improve the rotation accuracy of the moving tube 4 compared with the related art, thereby helping to improve the rotation accuracy of the drilling tool 7, and further helping to improve the molding quality of the skydrill. Through the first sealing component 5, the gap between the moving tube 4 and the end of the sleeve 21 close to the power box 1 can be sealed to prevent water from overflowing from the end of the sleeve 21 close to the power box 1; through the second sealing component 6, the gap between the moving tube 4 and the end of the sleeve 21 close to the driver 3 can be sealed to prevent water from overflowing from the end of the sleeve 21 close to the driver 3. In summary, when the moving tube 4 rotates relative to the sleeve 21, the first sealing component 5 and the second sealing component 6 can ensure the normal rotation of the moving tube 4 while ensuring the sealing performance between the moving tube 4 and the sleeve 21, and can also prevent water from dripping from above and causing damage to the parts of the cutting groove skydrill below. In addition, since the sleeve 21 is fixedly installed on the power box 1, it can prevent the sleeve 21 from rotating with the moving tube 4. The water inlet pipe 22 is arranged in the sleeve 21, which can prevent the water inlet pipe 22 from rotating with the moving pipe 4. When installing the external pipe, the external pipe can be directly installed at the water inlet pipe 22, without the need for an external rotating device to make the external pipe rotate with the water inlet pipe 22, which helps to simplify the structure and greatly reduces the difficulty of installing the external pipe.

[0050] Optionally, the drive 3 is configured as a hydraulic motor.

[0051] In one embodiment of the present application, see Figures 1 to 4 The stationary sleeve 2 further includes a boss 23, which is connected to the inner wall of the sleeve 21. The moving pipe 4 includes a water injection pipe 41, which is rotatably installed in the sleeve 21 and is located on a side of the boss 23 close to the power box 1. The first sealing assembly 5 includes a first sealing gasket ring 51, which is supported between the water injection pipe 41 and the boss 23.

[0052] With such arrangement, when the water injection pipe 41 rotates relative to the sleeve 21, the boss 23 and the first sealing gasket ring 51 can seal the gap between the boss 23 and the water injection pipe 41 to prevent water from overflowing from between the boss 23 and the water injection pipe 41. The sealing effect is good and the rotation of the water injection pipe 41 will not be interfered with.

[0053] In one embodiment of the present application, please refer to Figures 1 to 4 The water injection pipe 41 includes a first tube body 411 and a flange 412. The first tube body 411 is axially through-set and communicates with the sleeve 21. The flange 412 is connected to the outer wall of the first tube body 411 near the boss 23. The first sealing assembly 5 also includes a first nut 52 and a first elastic member 53. The first nut 52 is screwed to the inner wall of the sleeve 21 near the power box 1. The first elastic member 53 elastically abuts between the flange 412 and the first nut 52.

[0054] The working principle of this embodiment is as follows: when installing the device, first install the first sealing gasket ring 51 into the sleeve 21, and place the first sealing gasket ring 51 on the side of the boss 23 close to the power box 1, and then sleeve the sleeve 21 on the water injection pipe 41. After the sleeve 21 is sleeved on the outer periphery of the water injection pipe 41, install the first nut 52. After the first nut 52 is installed to the end of the sleeve 21 close to the power box 1, the first elastic member 53 is compressed and abuts between the first nut 52 and the flange 412. After the first nut 52 is installed, the sleeve 21 is finally fixed to the power box 1 by external bolts.

[0055] With such arrangement, when the first tube body 411 rotates relative to the sleeve 21, the flange 412 and the first sealing gasket ring 51 are in close contact through the first elastic member 53, which helps to further improve the sealing performance of the device and achieve a good sealing effect. In addition, the first nut 52 facilitates the disassembly and installation of the first sealing gasket ring 51 and the sleeve 21, facilitates maintenance and replacement, and helps to improve the convenience of use.

[0056] Optionally, the first elastic member 53 includes two first retaining rings 531 and a first elastic structure 532 . The two first retaining rings 531 are both sleeved on the first tube body 411 and are both located between the first nut 52 and the flange 412 . The first elastic structure 532 is sleeved on the first tube body 411 and is located between the two first retaining rings 531 .

[0057] With such a configuration, the first elastic structure 532 can transmit elastic force to the flange 412 through the first retaining ring 531, thereby facilitating close fit between the flange 412 and the first sealing gasket ring 51. In addition, the first retaining ring 531 prevents the first elastic structure 532 from directly contacting the first nut 52, thereby facilitating the first nut 52 to drive the first elastic structure 532 to compress.

[0058] Optionally, the first elastic structure 532 is configured as a spring.

[0059] Optionally, the first nut 52 is configured as two semicircular nuts.

[0060] With such arrangement, when installing the first nut 52, compared with the related art, the first nut 52 can be screwed directly into the sleeve 21 from the outside of the first tube body 411, without the need to pre-set the first nut 52 on the outer periphery of the first tube body 411, thereby reducing the processing difficulty.

[0061] In one embodiment of the present application, see Figures 1 to 4 The first sealing assembly 5 further includes a first bearing 54 , which is sleeved on the first tube body 411 and located between the flange 412 and the first elastic member 53 .

[0062] With such arrangement, when the flange 412 rotates relative to the first elastic member 53 , the first bearing 54 prevents the flange 412 and the first elastic member 53 from directly contacting each other, thereby facilitating the rotation of the flange 412 and preventing the first elastic member 53 from interfering with the rotation of the flange 412 .

[0063] In one embodiment of the present application, see Figures 1 to 4 The moving tube 4 also includes a force transmission tube 42, which is installed at the output end of the driver 3 and rotates around the axial direction under the drive of the driver 3, and is located on the side of the boss 23 close to the driver 3. The second sealing assembly 6 includes a second sealing gasket ring 61, which is supported between the force transmission tube 42 and the boss 23.

[0064] With such arrangement, the power of the driver 3 can be transmitted to the water injection pipe 41 through the power transmission pipe 42, so that the water injection pipe 41 rotates. When the power transmission pipe 42 rotates relative to the sleeve 21, the gap between the boss 23 and the power transmission pipe 42 can be sealed by the boss 23 and the second sealing gasket 61 to prevent water from overflowing from between the boss 23 and the power transmission pipe 42, with good sealing effect and without interfering with the rotation of the power transmission pipe 42.

[0065] In one embodiment of the present application, please refer to Figures 1 to 4 The force transmission tube 42 includes a second tube body 421 and a cover plate 422. The second tube body 421 is installed at the output end of the driver 3 and is axially penetrated. The cover plate 422 is connected to the second tube body 421 and shields the end of the second tube body 421 close to the boss 23. The second sealing assembly 6 also includes a second nut 62 and a second elastic member 63. The second nut 62 is screwed to the inner wall of the sleeve 21 close to the driver 3. The second elastic member 63 elastically resists between the cover plate 422 and the second nut 62.

[0066] The working principle of this embodiment is as follows: when installing the device, after the sleeve 21 is fixed to the power box 1 by external bolts, the second sealing gasket 61 is first placed on the side of the boss 23 facing away from the power box 1, and then the second tube 421 is placed in the sleeve 21. Then the second nut 62 is installed to the sleeve 21 away from the power box 1 to compress the second elastic member 63. After the second nut 62 is installed, the driver 3 is finally installed to the end of the sleeve 21 away from the power box 1 by external bolts, and the output shaft of the driver 3 is clamped to the inner wall of the second tube 421.

[0067] With such arrangement, when the second tube body 421 rotates relative to the sleeve 21, the cover plate 422 and the second sealing gasket ring 61 are in close contact through the first elastic member 53, which helps to further improve the sealing performance of the device and achieve a good sealing effect. In addition, the second nut 62 facilitates the disassembly and installation of the second sealing gasket ring 61, facilitates maintenance and replacement, and helps to improve the convenience of use.

[0068] Optionally, the second elastic member 63 includes two second retaining rings 631 and a second elastic structure 632 . The two second retaining rings 631 are both sleeved on the second tube body 421 and are both located between the second nut 62 and the flange 412 . The second elastic structure 632 is sleeved on the second tube body 421 and is located between the two second retaining rings 631 .

[0069] With such a configuration, the second elastic structure 632 can transmit elastic force to the cover plate 422 through the second retaining ring 631, so that the cover plate 422 and the second sealing gasket ring 61 can be closely fitted. In addition, the second retaining ring 631 prevents the second elastic structure 632 from directly contacting the second nut 62, so that the second nut 62 can drive the second elastic structure 632 to compress.

[0070] Optionally, the second elastic structure 632 is configured as a spring.

[0071] Optionally, the output shaft of the driver 3 and the inner wall of the second tube body 421 are connected via a spline.

[0072] Optionally, the second nut 62 is configured as two semicircular nuts.

[0073] With such arrangement, when installing the second nut 62, compared with the related art, the second nut 62 can be screwed directly into the sleeve 21 from the outside of the second tube body 421, without the need to pre-set the second nut 62 on the outer periphery of the second tube body 421, thereby reducing the processing difficulty.

[0074] In one embodiment of the present application, see Figures 1 to 4 The second sealing assembly 6 further includes a second bearing 64 , which is sleeved on the second tube body 421 and located between the cover plate 422 and the second elastic member 63 .

[0075] With such arrangement, when the cover plate 422 rotates relative to the second elastic member 63 , the second bearing 64 prevents the cover plate 422 and the second elastic member 63 from directly contacting each other, thereby facilitating the rotation of the cover plate 422 and preventing the second elastic member 63 from interfering with the rotation of the cover plate 422 .

[0076] In one embodiment of the present application, see Figures 1 to 4 The dynamic pipe 4 also includes a transmission frame 43, which is installed between the water injection pipe 41 and the power transmission pipe 42 and is used to transmit the power of the driver 3 to the water injection pipe 41 through the transmission frame 43.

[0077] With such arrangement, the transmission frame 43 is used to ensure that the external water source can normally enter the first tube body 411, and at the same time, it can ensure that the second tube body 421 transmits power to the first tube body 411, thereby avoiding the situation where the external water source cannot enter the sleeve 21.

[0078] In one embodiment of the present application, please refer to Figures 1 to 4 The transmission frame 43 includes a plurality of vertical rods 431 and a plurality of cross rods 432. The plurality of vertical rods 431 are all clamped between the water injection pipe 41 and the power transmission pipe 42, and are all extended along the axial direction; the plurality of cross rods 432 are all connected to the plurality of vertical rods 431, and are spaced apart along the axial direction.

[0079] Such arrangement, with the cooperation of the plurality of vertical rods 431 and the plurality of horizontal rods 432, helps to improve the structural stability of the transmission frame 43. When transmitting the power of the driver 3, it helps to improve the torsion resistance of the transmission frame 43, making it less prone to damage, and greatly reducing the failure rate of the device.

[0080] In one embodiment of the present application, see Figures 1 to 4 The transmission frame 43 also includes two flanges 433 , one flange 433 is connected to a plurality of vertical rods 431 and installed on the power transmission pipe 42 , and the other flange 433 is connected to a plurality of vertical rods 431 and installed on the water injection pipe 41 .

[0081] Such arrangement, through the two flanges 433, helps to improve the structural stability between the transmission frame 43 and the first tube body 411, and also helps to improve the structural stability between the transmission frame 43 and the second tube body 421, is not easy to loosen, is easy to transmit force, and has good anti-torsion effect.
