Description

Technical Field

[0001] The present invention relates to the technical field of mine drilling and reaming, and particularly to a drilling and reaming device, a system and a drilling and reaming construction method. Background Art

[0002] With the exhaustion of shallow resources and the rapid development of underground engineering, the geological conditions of deep mines have deteriorated, and the occurrence conditions of minerals are complex and changeable. The pneumatic down-the-hole hammer drilling technology has strong adaptability to complex geological conditions. As a result, the pneumatic down-the-hole hammer drilling technology has been widely used in many fields such as mine blasting hole drilling, hydrogeological well drilling, geological core exploration, engineering geological exploration, and anchoring and grouting engineering construction. The traditional pneumatic down-the-hole hammer drilling system mainly adopts the method of first drilling with a small diameter and then gradually expanding the hole diameter in reaming. This method not only has low efficiency but also high costs. Moreover, during deep hole drilling, due to the increase in hole wall friction and rock compressive strength, the components of the pneumatic down-the-hole hammer are prone to wear, and operators need to regularly check and timely replace damaged components. In addition, for relatively mature single pneumatic down-the-hole hammers, the large diameter drill rods of the bits are restricted and cannot be directly applied to the construction requirements of underground roadways, which limits the application scope of the pneumatic down-the-hole hammer drilling technology. These problems seriously affect the progress and efficiency of the underground roadway drilling and reaming project and limit the further development of the pneumatic down-the-hole hammer drilling technology. For the above reasons, it is necessary to design a pneumatic down-the-hole hammer drilling and reaming system and its construction method. Summary of the Invention

By adjusting the corresponding support shaft rods in the two adjusting assemblies on both sides to the same angle, the height of the drilling rig assembly is changed; by adjusting the corresponding support shaft rods in the two adjusting assemblies on both sides to different angles, the angle of the drilling rig assembly is changed; thereby improving the applicability of the drilling rig assembly and the efficiency of drilling and reaming.

[0055] In this embodiment, the two rotation axes 16 are supported between the support platform 103 and the support base 104 in parallel by the first support shaft rod 181, the second support shaft rod 182, the third support shaft rod 183, the fourth support shaft rod 184, the fifth support shaft rod 185, and the sixth support shaft rod 186, and the plane where the rotation axes 16 are located is respectively parallel to the support platform 103 and the support base 104; it should be understood that when there are multiple adjusting components, the multiple adjusting components can share the two rotation axes 16, and only need to distribute the multiple support shaft rods of each adjusting component among the two rotation axes 16 in parallel and evenly;

[0056] Here, two turntables 15 are respectively fixed to one end of two rotating axles 16. A rotating shaft rod 19 is sleeved outside the rotating axle 16, and a gear is provided between them, so that when the rotating axle 16 is adjusted by rotating the turntable 15, the rotating shaft rod 19 and the rotating axle 16 can be kept synchronous and rotate relatively through the gear;

[0057] Here, the first support shaft rod 181 and the second support shaft rod 182 are arranged crosswise to form a first X-shaped structure, and the first X-shaped structure is located between the support platform 103 and the plane where the two rotating shaft rods are located; the first ends of the first support shaft rod 181 and the second support shaft rod 182 are respectively fixedly connected to the bottom surface of the support platform 103, and their fixed connection positions with the bottom surface of the support platform 103 are symmetrical on the bottom surface of the support platform 103; the second end of the first support shaft rod 181 is rotatably connected to one of the rotating shaft rods, and the second end of the second support shaft rod 182 is rotatably connected to the other rotating shaft rod, and the rotation connection positions of the first support shaft rod 181 and the second support shaft rod 182 on the two rotating shaft rods are symmetrical; preferably, the second ends of the first support shaft rod 181 and the second support shaft rod 182 can be rotatably connected to the rotating shaft rod through gears respectively, so as to realize the angle adjustment of the first X-shaped structure formed by the first support shaft rod 181 and the second support shaft rod 182 through the mechanical rotation and positioning of the gears;

[0058] Here, the third support shaft rod 183 and the fourth support shaft rod 184 are arranged crosswise to form a second X-shaped structure, and the second X-shaped structure is located between the plane where the two rotating shaft rods are located and the support base 104, and the second X-shaped structure is vertically located below the first X-shaped structure; the first end of the third support shaft rod 183 is rotatably connected to one of the rotating shaft rods, and the first end of the fourth support shaft rod 184 is rotatably connected to the other rotating shaft rod, and the rotation connection positions of the third support shaft rod 183 and the fourth support shaft rod 184 on the two rotating shaft rods are symmetrical; preferably, the first ends of the third support shaft rod 183 and the fourth support shaft rod 184 can be rotatably connected to the rotating shaft rod through gears respectively, so as to realize the angle adjustment of the second X-shaped structure formed by the third support shaft rod 183 and the fourth support shaft rod 184 through the mechanical rotation and positioning of the gears;

[0059] The second ends of the third support shaft rod 183 and the fourth support shaft rod 184 are respectively fixedly connected to the top surface of the support base 104, and their fixed connection positions with the top surface of the support base 104 are symmetrical on the top surface of the support base 104; preferably, the second ends of the third support shaft rod 183 and the fourth support shaft rod 184 can be fixedly connected to the top surface of the support base 104 through the fixed axle center 101 to further ensure the stability of connection and support;

[0060] Here, the fifth support shaft rod 185 is arranged on one side of the second X-shaped structure formed by the third support shaft rod 183 and the fourth support shaft rod 184. The first end of the fifth support shaft rod 185 is rotatably connected to one of the rotating shaft rods, and the second end is slidably connected to the fourth support shaft rod 184. The sixth support shaft rod 186 is arranged on the other side of the second X-shaped structure formed by the third support shaft rod 183 and the fourth support shaft rod 184. The first end of the sixth support shaft rod 186 is rotatably connected to the other rotating shaft rod, and the second end is slidably connected to the third support shaft rod 183. The arrangement of the fifth support shaft rod 185 and the sixth support shaft rod 186 realizes the support of the entire adjustment assembly. Preferably, the first ends of the fifth support shaft rod 185 and the sixth support shaft rod 186 can be rotatably connected to the rotating shaft rods through gears respectively. The second ends of the fifth support shaft rod 185 and the sixth support shaft rod 186 can be slidably connected to the fourth support shaft rod 184 and the third support shaft rod 183 through the support centers 17 respectively.

[0061] It should be known that the cross arrangements among the first support shaft rod 181, the second support shaft rod 182, the third support shaft rod 183, the fourth support shaft rod 184, the fifth support shaft rod 185 and the sixth support shaft rod 186 are all located in the same plane to ensure the stability and uniformity during adjustment, and this plane is perpendicular to the support platform 103 and the support base 104. The second end of the first support shaft rod 181, the first end of the third support shaft rod 183 and the first end of the fifth support shaft rod 185 are mutually angled. The second end of the second support shaft rod 182, the first end of the fourth support shaft rod 184 and the first end of the sixth support shaft rod 186 are mutually angled (and correspond one by one to the mutual angles among the second end of the first support shaft rod 181, the first end of the third support shaft rod 183 and the first end of the fifth support shaft rod 185).

[0062] When adjusting the height of the drilling rig assembly, the two turntables 15 are rotated simultaneously and relatively (the number of rotations of the two is consistent), for example, the first turntable at the first end of the fifth support shaft 185 is rotated clockwise, and the second turntable at the first end of the sixth support shaft 186 is rotated counterclockwise. Since gears are provided between the rotating shaft 16 and the rotating shaft 19, gears are provided between the rotating shaft 19 and the first end of the fifth support shaft 185, and gears are provided between the rotating shaft 19 and the first end of the sixth support shaft 186, when the two turntables rotate relatively and drive the rotating shaft 16 and the rotating shaft 19 to rotate, through the meshing between the gears, the second end of the fifth support shaft 185 is pressed down to move on the fourth support shaft 184, and the second end of the sixth support shaft 186 is moved on the third support shaft 183. At this time, the second end of the fifth support shaft 185 is pressed down to move on the fourth support shaft 184, and the second end of the sixth support shaft 186 is pressed down to move on the third support shaft 183. The second end of the sixth support shaft 186 is away from each other, so that the second X-shaped structure formed by the third support shaft 183 and the fourth support shaft 184 increases the horizontal angle and decreases the vertical angle. When the vertical angle between the two decreases, the rotating shafts 19 on both sides are driven to approach each other. The rotating shafts 19 on both sides are close to each other and cooperate with the gear meshing between the second end of the first support shaft 181 and the second end of the second support shaft 182 to drive the first support shaft 181 and the second support shaft 182 to extend the first X-shaped structure (that is, the horizontal angle increases and the vertical angle decreases), so that its height increases and drives the adjustment of the height of the drilling rig assembly at the first end of the two, so as to complete the adjustment of the height increase of the drilling rig assembly; it should be known that the adjustment process of reducing the height of the drilling rig assembly is opposite to the above process, which will not be repeated here. When adjusting the angle of the drilling rig assembly, the adjustment process is the same as the above-mentioned height increase adjustment process, and it is only necessary to set the number of rotations of the two turntables 15 to be different; here, the number of rotations of the turntable 15 can be set according to actual needs.

[0063] See also Figures 1 to 3 In an optional embodiment of the present invention, the drilling rig assembly includes a drilling rig 11, a drill rod 4 and a drill bit 5; the drill rod 4 is arranged between the drilling rig 11 and the drill bit 5, one end of the drill rod 4 is transmission connected to the drilling rig 11 through a drill rod 12, and the other end of the drill rod 4 is fixedly connected to the drill bit 5.

[0064] Here, the output end of the drill rig 11 is fixedly connected to one end of the drill rod 12, and the other end of the drill rod 12 is fixedly connected to the drill rod 4; the drill rig 11 transmits power to the drill bit 5 through the drill rod 12 and the drill rod 4 to perform drilling and expansion.

[0065] like Figure 3As shown, in an alternative embodiment of the present invention, the drill pipe 4 includes a housing 42, a down-the-hole hammer piston unit, a positioning spline 46, and a buffer unit. Among them, the housing 42 is cylindrical, and an internally threaded connecting pipe 41 is provided at one end inside the housing 42 for connecting the drill rod 12; the down-the-hole hammer piston unit is arranged inside the housing 42 and is adjacent to the internally threaded connecting pipe 41, and one end of the down-the-hole hammer piston unit abuts against the other end of the internally threaded connecting pipe 41; the positioning spline 46 is arranged inside the housing 42 and is fixedly connected to the other end of the down-the-hole hammer piston unit, and the positioning spline 46 is used to adjust the direction of drilling and reaming; the buffer unit is arranged between the down-the-hole hammer piston unit and the positioning spline.

[0069] Here, the buffer unit can be a buffer spring. By arranging the buffer spring, support, connection, and buffering are provided for the positioning spline 46 and the down-the-hole hammer piston unit. When the drill bit 5 enters the hard rock area, the impact no longer collides with the drill pipe and the drill rod 12 after passing through the buffer spring, providing protection for the positioning spline 46 and the down-the-hole hammer piston unit, and at the same time reducing the probability of the drill bit being stuck during recovery.

[0071] Here, by setting the down-the-hole hammer piston unit, when the piston rod 44 moves between the internally threaded connecting pipe 41 and the piston cylinder 43, drilling and reaming operations are carried out; the piston cylinder 43 can be a down-the-hole hammer piston cylinder, and the piston rod 44 can be a down-the-hole hammer piston rod; using the down-the-hole hammer piston unit for down-the-hole hammer impact rotary rock breaking, on the one hand, the down-the-hole hammer piston unit has a long service life and can save the cost of drill tool use, and on the other hand, the down-the-hole hammer piston unit can use compressed air as power and does not need to use oil or mud as power, thereby reducing environmental pollution.

[0072] In an alternative embodiment of the present invention, the piston cylinder 43 and the buffer spring are of an integrally formed structure to facilitate the overall assembly of the equipment.
