A drilling and slag removal device for roadbed slopes

Abstract

This invention discloses a drilling and slag removal device for roadbed slopes, belonging to the field of geotechnical engineering machinery technology. The device mainly includes a multi-link structure, a guide rail structure, a drilling section, and a slag removal section. The multi-link structure drives the connected drilling rig beam rail to precisely position and angle the target drilling hole. The drilling section includes a drilling rig moving seat, drill rod, and drill bit that can move on the drilling rig beam rail. A slag removal motor drives a coaxial spiral sleeve fitted outside the drill rod. This sleeve has a cylinder body and spiral baffles outside the cylinder body, with an outer diameter equal to that of the drill bit. During drilling, the rotating spiral baffles continuously convey the drill cuttings generated behind the drill bit spirally upwards along the hole wall and discharge them outside the hole, overcoming the defects of difficult slag removal in deep holes and drill bit clogging. Simultaneously, the spiral conveying method significantly reduces dependence on high-pressure airflow, effectively suppressing dust diffusion caused by airflow carrying fine drill cuttings, and improving the cleanliness of the working environment. This invention significantly improves drilling efficiency and depth capability, while also offering environmental advantages.

Description

Technical Field

[0001] This invention belongs to the field of geotechnical engineering machinery technology, specifically relating to a drilling and slag removal device for roadbed slopes. Background Technology

[0002] Down-the-hole (DHH) drills, as highly efficient geological drilling equipment, are widely used in geotechnical engineering fields such as mining, slope protection, and geological exploration. Their core technology lies in using compressed gas to drive an impactor to generate high-frequency impact force, while simultaneously rotating the drill rod to drive the drill bit into the rock strata, achieving impact-rotation composite crushing. This equipment is typically equipped with an adjustable drill frame or robotic arm structure to adapt to drilling needs at different slope angles, and it possesses flexible positioning capabilities, especially in complex mountain environments. During drilling, the crushed rock cuttings are mainly blown out of the borehole opening against the flow of high-pressure air transported within the drill rod, achieving initial debris removal.

[0003] However, traditional down-the-hole drilling rigs have significant technical drawbacks in deep-hole operations: First, relying solely on airflow for cuttings removal becomes drastically less efficient at greater hole depths. The airflow cannot effectively carry away the drill cuttings at the bottom, leading to their continuous accumulation within the hole, eventually clogging the drill bit passage or jamming the drill rod, and in severe cases, causing equipment failure. Second, the high-speed airflow ejects large amounts of fine drill cuttings from the borehole opening, causing dust pollution at the work site, reducing visibility, polluting the environment, and endangering the respiratory health of operators. Furthermore, existing cuttings removal methods require high borehole wall stability, making them prone to collapse in fractured rock formations due to repeated impacts. These problems directly restrict the efficiency and quality of deep-hole construction. Summary of the Invention

[0004] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a drilling and slag removal device for roadbed slopes, which solves the technical problems of existing down-the-hole drilling rigs in deep hole operations, such as difficulty in removing drill cuttings, easy clogging of drill bits, and serious dust pollution caused by high-pressure airflow slag removal.

The slag discharge motor drives the spiral sleeve to rotate. The spiral sleeve includes a cylinder and a spiral baffle that spirally surrounds the outside of the cylinder. The outer diameter of the spiral baffle is equal to the outer diameter of the drill bit.

[0010] Optionally, the slag discharge section further includes a support frame structure, a belt ring, a main rotor, and a secondary rotor. The support frame structure is fixed on the drilling rig moving base, the slag discharge motor is mounted on the support frame structure, the main rotor is fixed at the end of the slag discharge motor, the secondary rotor is coaxially arranged at the end of the cylinder, the belt ring is sleeved on the outside of the main rotor and the secondary rotor, and both the main rotor and the secondary rotor are provided with an inner annular groove to block the belt ring.

[0011] Optionally, the support frame structure includes a base frame and a top frame that is laterally movable on the base frame. A transverse groove is formed on the base frame, and the support end of the top frame is slidably disposed in the transverse groove. Returning springs are provided on both sides of the top frame between the top frame and the transverse groove.

[0012] Optionally, the spiral baffle has two sections, one of which has several air holes on its side away from the drill bit. The cylinder body has an air passage communicating with the air holes. The support frame structure also includes a short rail and an air ring. The short rail is parallel to the drilling rig beam rail and fixed on the base frame. The air ring is slidably disposed on the short rail. An air groove is formed on the inner side of the air ring. Two parallel air sealing rings are provided on the outer side of the cylinder end. The air ring is rotatably sealed on the air sealing ring. The air groove communicates with the air passage. The system also includes an air pump disposed on the drilling rig moving base. The air pump communicates with the air ring.

[0013] Optionally, a plurality of water holes are opened on the side of another spiral baffle away from the drill bit, and a water channel communicating with the water holes is provided in the cylinder. The support frame structure also includes a water ring, which is slidably mounted on the short rail. A water groove is opened on the inner side of the water ring. Two parallel water sealing rings are provided on the outer side of the end of the cylinder. The water ring is rotatably mounted on the water sealing ring. The water groove is communicating with the water channel. It also includes a water pump and a water tank mounted on the drilling rig moving base. The water pump is connected to the water tank and the water ring respectively.

[0014] Optionally, it also includes two folded hoses, the ends of which are fixed to the base frame. One of the folded hoses is connected to the air ring and the air pump respectively, and the other folded hose is connected to the water ring and the water pump respectively.

[0015] Optionally, the guide rail structure also includes a guide end seat, which is fixed to the top side of the end of the drilling rig beam rail.

The rotating bin has a fan-shaped column structure and is rotatably mounted at the feed end of the slag collection bin. During drilling, one side of the rotating bin is attached to the surface to be drilled.

[0017] Optionally, the side edges of the rotating chamber are also wrapped with a layer of soft rubber strips.

[0018] Optionally, the outer sides of both the gas sealing ring and the water sealing ring are provided with several sealing rings.

[0019] The beneficial effects of this invention are as follows:

[0020] The specific position and inclination angle of the drilling rig beam rail are adjusted by a multi-link mechanism to provide the required drilling position for the drilling section. The drilling section is powered by compressed gas. Driven by the impactor, the gas is delivered to the drill bit through the drill rod. The drill bit rotates and impacts the drilling. With the movement of the moving seat, the drill bit extends into the rock strata to obtain a deep hole of the required depth and diameter. This device is also equipped with a slag removal section. The slag removal section moves with the moving seat. Driven by the slag removal motor, the threaded sleeve rotates coaxially on the outside of the drill rod. The rotation of the threaded sleeve through the spiral baffle gradually transfers the drill cuttings broken by the drill bit and discharged behind the drill bit out of the borehole. Compared with the air transfer of drill cuttings by the gas blown out of the drill bit, this structure can overcome the problem that drill cuttings in deeper holes cannot be blown out, avoid the blockage of the drill bit by drill cuttings accumulation, and prevent the spread of dust and low visibility caused by the air blowing out of drill cuttings through the spiral baffle, so as to achieve rapid removal of drill cuttings and collection of drill cuttings below the borehole.

[0032] Please refer to the figures. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of the invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the disclosed technical content. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0033] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0034] This invention provides a drilling and slag removal device for roadbed slopes, such as... Figure 1 As shown, the system includes a multi-link structure 1, a guide rail structure 2, a drilling section 3, and a slag removal section 4. The multi-link structure 1 is a hydraulically driven robotic arm. The guide rail structure 2 includes a drilling rig beam rail 21, the lower middle part of which is connected to the moving end of the multi-link structure 1. The robotic arm is mounted on a mobile device, and through the movement of the mobile device and the rotation of the robotic arm, the drilling rig beam rail 21 is positioned in the drilling position, as shown. Figures 3-7 As shown, the drilling section 3 includes a drilling rig moving base 31, a drill rod 32, and a drill bit 33. The drilling rig moving base 31 is movably mounted on the drilling rig beam rail 21. The drill rod 32 is mounted on the drilling rig moving base 31 and is parallel to the drilling rig moving base 31. The drill bit 33 is located at the end of the drill rod 32. The slag discharge section 4 includes a slag discharge motor 41 and a spiral sleeve 42. The slag discharge motor 41 is mounted on the drilling rig moving base 31. The spiral sleeve 42 is coaxially rotatably mounted on the outside of the drill rod 32. The slag discharge motor 41 drives the spiral sleeve 42 to rotate. The spiral sleeve 42 includes a cylinder 421 and a spiral baffle 422 spirally surrounding the outside of the cylinder 421. The outer diameter of the spiral baffle 422 is equal to the outer diameter of the drill bit 33.

[0035] This device adjusts the specific position and inclination angle of the drilling rig beam rail 21 via a multi-link mechanism to provide the required drilling position for the drilling section 3. The drilling section 3 is powered by compressed gas. Driven by the impactor, the gas is delivered to the drill bit 33 through the drill rod 32. The drill bit 33 rotates and impacts the drilling. With the movement of the moving seat, the drill bit 33 extends into the rock strata to obtain a deep hole of the required depth and diameter. This device also includes a slag discharge section 4, which moves with the moving seat. Driven by the slag discharge motor 41, the threaded sleeve... The screw sleeve rotates coaxially on the outside of the drill rod 32. The rotation of the spiral baffle 422 will gradually transfer the drill cuttings broken by the drill bit 33 and discharged to the back of the drill bit 33 out of the borehole. Compared with the air transfer of drill cuttings by the gas blown out by the drill bit 33 alone, this structure can overcome the problem that drill cuttings in deeper holes cannot be blown out, avoid the blockage of the drill bit 33 by the accumulation of drill cuttings, and avoid the problem of dust diffusion and low visibility caused by the air blowing out of drill cuttings by the spiral baffle 422, so as to achieve the rapid removal of drill cuttings and the collection of drill cuttings below the borehole.

[0036] In further proposals, such as Figure 7 As shown, the slag discharge section 4 also includes a support frame structure 43, a belt ring 44, a main rotor 45, and an auxiliary rotor 46. The support frame structure 43 is fixed on the drilling rig moving base 31. The slag discharge motor 41 is mounted on the support frame structure 43. The main rotor 45 is fixed at the end of the slag discharge motor 41. The auxiliary rotor 46 is coaxially arranged at the end of the cylinder 421. The belt ring 44 is sleeved on the outside of the main rotor 45 and the auxiliary rotor 46. Both the main rotor 45 and the auxiliary rotor 46 are provided with inner annular grooves to block the belt ring 44.

[0037] In this structure, the slag discharge motor 41 drives the rotation of the spiral sleeve 42 via belt drive. When the spiral sleeve 42 is jammed, friction and slippage occur between the belt ring 44 and the main rotor 45 and the auxiliary rotor 46, preventing motor damage caused by the spiral sleeve 42 being jammed by drill cuttings. Furthermore, the belt ring 44 is extensible, allowing the spiral sleeve 42 to move a small distance along the drill rod 32 when obstructed, improving the adaptability of the spiral sleeve 42's free rotation speed and free movement process when transferring drill cuttings, and preventing the drill rod 32 from affecting the movement of the spiral sleeve 42 during its travel.

[0038] In further proposals, such as Figure 2As shown, the support frame structure 43 includes a base frame 431 and a top frame 432 that is laterally movable on the base frame 431. The base frame 431 extends upward from both sides of the spiral sleeve 42, and a transverse groove 4311 is formed on the support block structure. The top frame 432 includes extension blocks that are respectively fixed on both sides of the slag discharge motor 41. The support ends of the extension blocks are slidably disposed in the transverse groove 4311. Returning springs 433 are provided between the two sides of the top frame 432 and the transverse groove 4311.

[0039] In this structure, the slag discharge motor 41 moves flexibly laterally on the support frame by supporting the top frame 432. When the spiral sleeve 42 transfers drill cuttings, the spiral sleeve 42 can swing back and forth a greater distance and has elastic return capability. During the movement of the spiral sleeve 42, while ensuring the transmission capability of the belt ring 44, the freedom of movement of the elastic sleeve is further improved. With the support of the return spring 433, the spiral sleeve 42 moves forward in a back-and-forth swaying manner during the movement, which can sweep the drill cuttings in the hole and avoid drill cuttings from clogging.

[0040] In further proposals, such as Figure 1 , Figure 6 and Figure 7As shown, there are two spiral baffles 422. One of the spiral baffles 422 has several air holes 423 on its side away from the drill bit 33. The cylinder 421 has an air passage 424 communicating with the air holes 423. The support frame structure 43 also includes a short rail 434 and an air ring 435. The short rail 434 is parallel to the drilling rig beam rail 21 and fixed to the base frame 431. The air ring 435 is slidably mounted on the short rail 434. An air groove 4351 is formed on the inner side of the air ring 435. Two parallel air-sealing rings 425 are provided on the outer side of the end of the cylinder 421. Several sealing rings are provided on the outer side of each air-sealing ring 425. The air ring 435 is rotatably mounted on the air-sealing ring 425. The air groove 4351 communicates with the air passage 424. It also includes an air... Pump 51, the air pump 51 is connected to the air ring 435; another spiral baffle 422 has several water holes 426 on its side away from the drill bit 33, the cylinder 421 has a water channel 427 connected to the water holes 426, the support frame structure 43 also includes a water ring 436, the water ring 436 is slidably mounted on the short rail 434, the water ring 436 has a water groove 4361 on its inner side, the outer side of the end of the cylinder 421 has two parallel water sealing rings 428, the outer side of the water sealing rings 428 has several sealing rings, the water ring 436 is rotatably mounted on the water sealing rings 428, the water groove 4361 is connected to the water channel 427; it also includes a water pump 52 and a water tank 53 mounted on the drilling rig moving base 31, the water pump 52 is connected to the water tank 53 and the water ring 436 respectively.

[0041] In this structure, air passages 424 and water passages 427 are respectively opened inside the rotating spiral sleeve 42, and air holes 423 and water holes 426 are respectively opened on the spiral baffle 422 away from the forward direction of the drill bit 33. Utilizing the spaced and encircling structure of the two spirals, the air holes 423 and water holes 426 are evenly distributed on the outside of the threaded sleeve. The air holes 423 are supplied with gas by the air pump 51, and the water holes 426 are supplied with water by the water pump 52 and the water tank 53. Through the air ring 435 and water ring 436 that are set to rotate in a sealed manner, the gas jet can provide staged assistance to the drill cuttings in the hole during the rotation of the spiral sleeve. The movement of the water jet helps prevent the accumulation of drill cuttings and cools the spiral sleeve 42 to a certain extent, thereby reducing the temperature of the drill rod 32 and drill bit 33. This is because the local temperature of the ball teeth of drill bit 33 can exceed 600°C when impacting the rock. At high temperatures, the wear resistance of cemented carbide decreases sharply. Cooling can prevent the tooth tip from softening due to annealing or the propagation of microcracks. Sudden cooling and heating can cause thermal stress cracks in the drill bit 33 body. Continuous cooling keeps the temperature stable. Furthermore, through the cooperation of airflow and water flow, the cooling airflow can quickly remove heat from the bottom of the hole, preventing the rock from "plasticizing" due to high temperature and reducing the critical crushing strength of the rock.

[0042] In further proposals, such as Figure 3 As shown, it also includes two folded hoses 54, the ends of which are fixed to the base frame 431. One of the folded hoses 54 is connected to the air ring 435 and the air pump 51 respectively, and the other folded hose 54 is connected to the water ring 436 and the water pump 52 respectively.

[0043] In this structure, the folded hose 54 is always connected to the air ring 435 and the air pump 51, as well as the water ring 436 and the water pump 52, as the threaded sleeve swings back and forth. This ensures the normal input operation of the water pump 52 and the air pump 51 and prevents the conventional pipe from falling off, separating, or even being damaged under repeated swinging.

[0044] In further proposals, such as Figure 5 As shown, the guide rail structure 2 also includes a guide end seat 22, which is fixed to the top side of the end of the drilling rig beam rail 21. The guide end seat 22 has a support hole with an inner diameter equal to that of the drill bit 33, and the support hole is coaxially arranged with the drill bit 33.

[0045] By setting the guide end seat 22, the longer drill rod 32 and threaded sleeve can be supported and guided, avoiding deformation of the drill rod 32 and threaded sleeve.

[0046] In further proposals, such as Figure 5 As shown, it also includes a slag collection bin 61 and a rotating bin 62 for collecting drill cuttings. The slag collection bin 61 is fixed to the end of the drilling rig beam rail 21. The drill bit 33 passes through the slag collection bin 61. The rotating bin 62 has a fan-shaped column structure. The rotating bin 62 is rotatably installed at the feed end of the slag collection bin 61. During the drilling process, one side of the rotating bin 62 is attached to the surface to be drilled.

[0047] By setting up a slag collection bin 61, drill cuttings are collected and utilized, which facilitates the clogging of subsequent blast holes and avoids excessive dust on site caused by the random scattering of drill cuttings. By setting up a rotating bin 62, it can adapt to different drilling angles and always keep the rotating bin 62 in close contact with the drilling surface, which is conducive to the collection of drill cuttings and avoids excessive drill cuttings falling out.

[0048] In further proposals, such as Figure 5 As shown, the side edge of the rotating chamber 62 is also wrapped with a layer of soft rubber strip 63.

[0049] The further designed soft adhesive strip 63 can conform to the uneven drilled surface, further improving the ability to collect drill cuttings, and also preventing direct collision between the rotating chamber 62 and the drilled surface.

[0050] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
