Description

Technical Field

[0001] The present invention relates to the technical field of drilling equipment, in particular to a flying wing hydraulic impactor. Background Art

[0002] Typically, drilling in hard rock requires a down-the-hole drill and pneumatic impactor to achieve the desired hole size. However, in loose geology, such as quicksand or muddy soil, unprotected holes can easily collapse, resulting in drill bit sticking and burial, and failing to meet construction requirements. To address this, casing must be inserted into the hole to protect the borehole wall. This technique is known as casing drilling.

[0003] Regarding hole diameter, the larger the borehole diameter, the greater the power required to drive the actuator, which in turn increases the size and weight of the machine. Working in complex terrain (such as mountainous areas) can be extremely inconvenient when climbing uphill. For large-diameter drilling (e.g., holes larger than 600 mm), rotary drilling rigs can be used, but they are effective in fill, clay, silt, sand, and layers with some sand and gravel. They are suitable for drilling in rock formations with pressures below 60 MPa, but are not suitable for formations with higher hardness. Alternatively, a down-the-hole drill combined with a cluster down-the-hole hammer can be used. However, since these drilling and deslagging rigs use compressed gas, they require an air compressor as the power source. Air compressors are often energy-inefficient, with a conversion rate of approximately 20% of the engine's output. This requires a large number of air compressors to complete the operation, making transportation difficult and costly. Furthermore, both methods require casing installation before drilling, making simultaneous drilling with the casing impossible. To address these issues, a flying wing hydraulic impactor is proposed.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] The present invention provides the following technical solutions:

[0036] like Figure 1-12As shown, a wing hydraulic impactor includes a hydraulic impact device 1, a power mechanism 2 and a wing drill bit 3. The bottom of the hydraulic impact device 1 is connected to the power mechanism 2 through a flange connection. The flange connection makes the hydraulic impact device 1 and the power mechanism 2 more stable when connected together, thereby improving its stability during operation. The power mechanism 2 includes an impact chamber 202, and the bottom of the impact chamber 202 is connected to the power cavity 204. The bottom of the impact chamber 202 is connected to the power cavity 204. The wing drill bit 3 includes a guide joint 301, and the top of the guide joint 301 is arranged in the impact chamber 202. The hydraulic impact device is used to impact the guide joint 301, and a card slot 401 is provided in the middle of the guide joint 301. A drill pin 4 is provided inside the impact chamber 202, and the drill pin 4 is stuck in the card slot 401, and the height of the card slot 401 is greater than the height of the drill pin 4, and the drill pin 4 is horizontally fixed on the inner wall of the impact chamber 202, so that the guide joint 301 can have a space for up and down displacement, and the bottom side wall of the guide joint 301 The intermediate gear 205 is longitudinally connected through the connecting assembly, and a driving mechanism for driving the intermediate gear 205 to rotate is provided in the power chamber 204. The bottom of the guide joint 301 is rotatably connected to the center drill bit 304. A plurality of rotor blocks 303 are arranged in an array at the edge of the top surface of the center drill bit 304. The top surface of the center drill bit 304 is provided with a guide groove 307 for use with the rotor block 303. The bottom side wall of the guide joint 301 is provided with a receiving groove 308 adapted to the rotor block 303, and the rotor block 303 is provided with a sliding device. Placed in the accommodating groove 308, a cam structure 306 is fixedly provided in the center of the top surface of the center drill bit 304, and the side wall of the rotor block 303 close to the cam structure 306 is arranged in an arc shape, and the side wall of the cam structure 306 is provided with an arc-shaped protrusion corresponding to the rotor block 303. Through the above arrangement, the hydraulic impactor consists of a hydraulic impact device 1, a power mechanism 2 and a wing drill bit 3. It has a simple structure and is easy to assemble, maintain and transport, thereby reducing the transportation burden, being able to cope with various construction environments and saving construction costs.

[0037] When the impactor is drilling a hole in the rock, the intermediate gear 205 is first driven to rotate by the driving mechanism, and the intermediate gear 205 drives the guide joint 301 to rotate through the connecting assembly. At this time, the receiving groove 308 at the bottom of the guide joint 301 clamps the rotor block 303, so that the rotor block 303 slides on the surface of the center drill bit 304 through the guide groove 307, and the rotor block 303 rotates to the arc-shaped protrusion of the cam structure 306. At this time, the top of the arc-shaped protrusion presses against the side wall of the rotor block 303. When the guide joint 301 continues to rotate, the guide joint 301 drives the center drill bit 304 to rotate together, and at this time the rotor block 303 is unscrewed from the receiving groove 308, so that the diameter of the drill bit for drilling the rock hole increases. In the drilling work, the larger the diameter of the hole, the greater the power required to drive the actuator to move, and thus the larger the size and weight of the machine. In complex terrain environments, such as mountains The wing hammer can adjust the diameter of the rock drilling drill bit, so there is no need to carry and transport a large driving actuator, which can reduce the transportation cost and improve the practicality and applicability of the wing hammer. The hammer is easy to assemble and maintain, which improves the convenience of the hammer. In order to enable the hammer to drill holes better, the guide joint 301 can be impacted by the hydraulic impact device, so that the guide joint 301 can have a downward impact force, and the guide joint 301 drives the center drill bit 304 to impact downward. During the drilling process, the drilling rig propulsion beam is used to propel the center drill bit 304. After each impact, when the wing drill bit 3 contacts the bottom of the hole, the bottom of the hole gives the wing drill bit 3 a reaction force, so that the wing drill bit 3 can return to the impact position, forming a cyclic impact motion, thereby improving the hole-drilling efficiency of the hammer.

[0038] During the drilling process, when encountering quicksand geology, the top of the power mechanism can be connected to the sleeve, so that the sleeve can be against the hole wall to prevent the hole wall from collapsing, and since the diameter of the drill bit of the drilling can be increased by unscrewing the rotor block 303, the drill hole diameter is larger than the outer wall diameter of the sleeve. During the drilling process, the sleeve can fall by its own weight to achieve synchronous pipe drilling. When the drill bit needs to be removed, the guide joint 301 can be driven to reverse by the power mechanism, so that the guide joint 301 drives the center drill bit 304 to rotate in the opposite direction, so that the accommodating groove 308 on the side wall of the guide joint 301 can drive the rotor block 303 to slide on the guide groove 307, so that the rotor block 303 slides to the innermost side of the arc-shaped protrusion on the side wall of the cam structure 306, and then the rotor block 303 is retracted from the accommodating groove 308, so that the drill bit diameter of the drilling hole is reduced, and then the drill bit can be easily taken out of the sleeve. Through the above process, the hammer can achieve synchronous drilling with the pipe, avoid the collapse of the hole wall, and can easily remove the wing drill bit 3.

[0039] The flange connection part includes a connecting flange 103 connected to the bottom of the hydraulic impact device and a connecting plate 201 connected to the top of the power mechanism. The connecting flange 103 is connected to the connecting plate 201. The connecting flange 103 and the connecting plate 201 can be connected by a number of bolts and nuts, making them more stable when connected together, thereby making the hydraulic impact device 1 and the power mechanism 2 more stable when connected together, and improving their stability during operation.

[0040] The hydraulic impact device includes an upper cylinder body 101 and a piston-in-cylinder body 102 connected to the bottom of the upper cylinder body 101. The bottom output end of the piston-in-cylinder body 102 is connected to an impact piston 104 for impacting the guide joint 301. The impact piston 104 is driven by the piston-in-cylinder body 102 to perform reciprocating motion, so that the piston-in-cylinder body 102 can continuously impact the guide joint 301, so that the guide joint 301 can continuously impact the bottom of the hole with the center drill bit 304, thereby achieving the purpose of improving the hole opening efficiency.

[0041] The bottom side walls of the piston cylinder 102 are evenly connected with several groups of reinforcing ribs 5, and the bottom of the reinforcing ribs 5 is connected to the top surface of the connecting plate 201. The bottom side walls of the impact chamber 202 are evenly connected with several groups of reinforcing ribs 5, and the bottom of the reinforcing ribs 5 is connected to the top surface of the power cavity 204. Through such an arrangement, the hydraulic impact device 1 is more stably connected to the power structure, and the connection between the impact chamber 202 and the power cavity 204 can also be more stably, thereby improving the stability of the impactor.

[0042] The connecting assembly includes a rectangular spline 305 arranged on the bottom side wall of the guide joint 301. The guide joint 301 is longitudinally arranged in the center of the intermediate gear 205, and a rectangular groove adapted to the rectangular spline 305 is provided in the center of the intermediate gear 205. Through the above arrangement, the intermediate gear 205 and the rectangular spline 305 can be better matched. When the driving structure drives the intermediate gear 205 to rotate, the rectangular groove in the middle thereof cooperates with the rectangular spline 305, and can rotate better. When the guide joint 301 is impacted downward by the impact piston, the rectangular spline 305 can slide up and down in the rectangular groove, thereby not affecting the longitudinal movement of the guide joint 301.

[0043] The driving mechanism includes multiple groups of hydraulic motors 203 equidistantly arranged on the top surface of the power chamber 204. The output end of the hydraulic motor 203 passes through the top of the power chamber 204 and is connected to the driving gear 206. An intermediate gear 205 is provided in the middle of the power chamber 204. The intermediate gear 205 is arranged between the multiple groups of driving gears 206, and the intermediate gear 205 and the driving gear 206 are meshed with each other. Through such an arrangement, the hydraulic motor 203 drives the driving gear 206 to rotate, and the driving gear 206 drives the intermediate gear 205 to rotate during the rotation process. Then the intermediate gear 205 drives the guide joint 301 through the rectangular groove and the rectangular spline 305, thereby driving the wing drill bit 3 to rotate through the guide joint 301, so that the hole opening efficiency of the wing drill bit 3 is more outstanding.

[0044] An air guide hole 302 is provided in the middle of the guide joint 301, an exhaust hole 310 connected to the air guide hole 302 is provided in the center drill bit 304, the output end of the exhaust hole 310 passes through the bottom of the center drill bit 304, a plurality of slag discharge grooves 309 are arranged in an array at the bottom of the center drill bit 304, and the center drill bit 304 is arranged at one end of the slag discharge groove 309, a slag collecting bucket 6 is provided on the top of the power chamber 204, and a plurality of embedded grooves 601 are equidistantly provided at the bottom of the slag collecting bucket 6, and a plurality of embedded grooves 601 are provided on the top of the power chamber 204. 01 is equipped with an embedded block 602, and a plurality of hanging holes 603 are equidistantly arranged on the side wall of the top of the slag collecting bucket 6. The slag discharge groove 309 can not only improve the drilling efficiency of the center drill bit, but also guide the slag produced by drilling to one side to prevent the residue from affecting the drilling of the center drill bit 304. During the drilling process, the slag collecting bucket 6 is inserted into the embedded block 602 on the top of the power chamber 204 through the embedded groove 601, so that the slag collecting bucket 6 is fixed on the top of the power chamber 204, and then the high-pressure gas can be passed through the air pipe. The gas is blown out from one end of the slag discharge groove 309, and blown out from the end of the slag discharge groove 309 close to the center of the center drill bit 304. The high-pressure gas blown out blows the rock debris produced by drilling to the side of the center drill bit 304. At this time, the bottom of the hole has high-pressure gas blown out, and the high-pressure gas blows upward along the side of the wing drill bit 3, so that the fine rock debris can be blown out of the hole, and the large rock debris can be blown to the side of the center drill bit 304. In the slag bucket 6, when the slag bucket 6 is full of rock slag, a connecting tool with a hook can be used to hang the hook on the hanging hole 603, and then the slag bucket 6 is hooked and pulled out. After cleaning, the slag bucket 6 is put back and enters the next drilling cycle. Through the above operations, the flying wing hydraulic impactor can blow the smaller rock slag generated by drilling out of the hole during the drilling process and collect the larger rock slag, thereby avoiding the rock slag affecting the opening efficiency during the drilling process, thereby improving the opening efficiency of the flying wing hydraulic impactor.

[0045] The bottom of the rotor block 303 away from the cam structure 306 is tilted. With this arrangement, the rotor block 303 can better break the side wall of the hole, thereby further improving the drilling efficiency of the drill bit.

[0046] The side walls of the center drill bit 304 are provided with a plurality of groups of grooves at equal intervals. With such an arrangement, the center drill bit 304 can perform a better drilling operation and can more effectively break the gravel and soil on the side walls of the hole.

[0047] The working principle of a flying wing hydraulic impactor of the present invention is as follows:

[0048] At the same time, the hydraulic motor 203 is started, and the hydraulic motor 203 drives the driving gear 206 to rotate. The driving gear 206 drives the intermediate gear 205 to rotate. The intermediate gear 205 drives the guide joint 301 to rotate through the cooperation of the rectangular groove and the rectangular spline 305. The guide joint 301 drives the center drill bit 304 to rotate. When the center drill bit 304 rotates, it drives the receiving groove 308 to rotate. The receiving groove 308 drives the rotor block 303 to rotate. The rotor block 303 slides on the surface of the center drill bit 304 through the guide groove 307, slides out of the receiving groove 308, and reaches the top of the arc-shaped protrusion on the side wall of the cam structure 306. , increasing the diameter of the entire wing drill bit 3, at this time the guide joint 301 drives the center drill bit 304 to rotate together, thereby achieving the effect of opening the hole, and then starting the hydraulic impact device, the hydraulic impact device drives the impact piston 104 to reciprocate, and makes the impact piston 104 repeatedly strike the guide joint 301, so that the guide joint 301 drives the center drill bit 304 to have a downward force, at this time the center drill bit 304 touches the bottom of the hole, and after the center drill bit 304 touches the bottom of the hole, there will be a reaction force, so that the center drill bit 304 is transmitted to the guide joint 301, the guide joint 301 moves upward, and then continues to be struck by the impact piston 104, completing the reciprocating motion. Movement, when the guide joint 301 makes longitudinal reciprocating motion, the slot 401 is stuck on the drill pin 4. Since the height of the slot 401 is greater than the height of the drill pin 4, the slot 401 moves up and down on the drill pin 4, and when the impactor is drilling, a sleeve is set on the outer wall. Due to the sliding out of the rotor block 303, the diameter of the drill hole is larger than the outer wall of the sleeve. The sleeve falls by its own weight to achieve pipe drilling. The embedded groove 601 at the bottom of the slag collecting bucket 6 and the embedded block 602 at the top of the power chamber 204 can also be engaged with each other, so that the slag collecting bucket 6 is set at the top of the power chamber 204, and then the high-pressure gas can be passed into the cylinder body of the piston through the air pipe. , then enters the exhaust hole 310 through the air guide hole 302 in the guide joint 301, and is finally blown out from one end of the slag discharge groove 309, and is blown out from the end of the slag discharge groove 309 close to the center of the center drill bit 304. The blown high-pressure gas blows the rock debris generated by drilling to the side of the center drill bit 304. At this time, due to the high-pressure gas blown out from the bottom of the hole, the high-pressure gas blows upward along the side of the wing drill bit 3, so that the fine rock debris can be blown out of the hole, and the large rock debris is blown into the slag collecting bucket 6. When the slag collecting bucket 6 is full of rock debris, a connecting tool with a hook can be used to hang the hook on the hanging hole 603, and then the slag collecting bucket 6 can be hooked up and pulled out for cleaning.

[0049] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as such modifications are within the scope of the claims of the present invention, they are protected by patent law.
