Description

Technical Field

[0001] The invention belongs to the technical field of tunnel engineering, and in particular relates to a drilling device for tunnel engineering construction. Background Art

[0002] The main function of tunnels is to serve as traffic passages, including highway tunnels, railway tunnels, underwater tunnels, subways and pedestrian tunnels. They can provide convenient transportation routes, allowing vehicles, trains or pedestrians to safely and quickly pass through natural obstacles such as mountains, rivers, lakes and oceans. During the construction of tunnels, in order to facilitate the installation of various fixed structures, such as cable racks, pipe racks, lighting equipment, etc., holes are often drilled on the top wall and side wall of the tunnel. These holes can ensure that various facilities are firmly attached to the tunnel wall and improve the safety and stability of the facilities inside the tunnel. At the same time, for tunnels that have been built, grouting reinforcement, drainage and other repair work can be carried out by drilling holes in the side walls, thereby extending the service life of the tunnel and ensuring the safety of vehicles and pedestrians.

[0003] In order to prevent the dust and debris generated during the drilling process from causing harm to the construction workers, the equipment currently used for drilling holes in the side walls of tunnels usually has a corresponding dust collection and removal structure at the drill bit to block the spread of dust and debris, effectively reducing the harm of dust and debris to the construction workers. However, these dust collection and removal structures are enclosed on the sides of the drill rod, and the collected dust and debris are difficult to be discharged in time and accumulate in the dust collection and removal structure. Especially in construction operations with deep drilling or large apertures, excessive accumulation of debris and dust not only increases the load-bearing burden of the drill rod, but also increases the contact range of the accumulated debris and dust with the drill rod, increasing the friction area with the drill rod, causing the drill rod to wear faster, thereby affecting the drilling accuracy of the drill rod and affecting the normal operation of the drill rod. For example, a Chinese patent with publication number CN113175299A provides a drilling device for tunnel engineering construction, including a frame, a sliding bracket and a first driving device for driving the sliding bracket to slide in a horizontal direction are provided on the frame, and a drill rod and a second driving device for driving the drill rod to rotate at high speed are provided on the sliding bracket; the frame is also provided with a support frame and an adjusting sleeve, the adjusting sleeve is fixedly connected with a telescopic sealing tube, and the telescopic sealing tube is rotatably connected to the drill rod; and a sealing plate is also provided at the front end of the telescopic sealing tube. When in use, the position of the adjusting sleeve is controlled to make the end face of the adjusting sleeve closely fit the punching section, and the cooperation of the telescopic sealing tube and the sealing plate seals the working end of the entire drill rod, so that the dust generated by the drilling can be sealed to prevent it from escaping. However, during the drilling process, dust and debris will accumulate in the telescopic sealing tube. At the same time, some dust and debris will also accumulate in the through hole on the sealing plate that is adapted to the entry and exit of the drill rod. As the amount of dust and debris accumulates, the weight on the front end of the drill rod increases, and some dust and debris are caused to adhere closely to the side wall of the drill rod, thereby increasing the friction surface with the drill rod and accelerating the wear of the drill rod. If not handled in time, as the amount of accumulation increases, the weight of the front end of the drill rod becomes larger, resulting in a weight burden and even affecting the normal operation of the drill rod. Another example is the Chinese patent with publication number CN220849604U, which discloses a cylindrical structure formed by bonding a first protective plate and a second protective plate to wrap a drilling machine, and slidingly slidably set a first inner plate and a second inner plate inside the first protective plate and the second protective plate, the first inner plate and the second inner plate fit with the wall surface of the drill hole, and as the drilling machine continues to drill, the first inner plate and the second inner plate squeeze the spring inward, so that the first inner plate and the second inner plate always wrap the drilling machine to prevent dust from splashing, and when the slider separates the first protective plate and the second protective plate, it is not only convenient to disassemble and assemble the drilling machine, but also convenient to clean the dust entering the inside.Compared with the above-mentioned patent CN113175299A, this device can conveniently handle the collected dust and debris after drilling is completed, but it is still unable to discharge the debris and dust in time during the drilling process, resulting in the accumulation of debris and dust inside the first protective plate and the second protective plate. Especially when drilling at the top of the tunnel, the accumulated debris and dust will directly contact the drilling machine, affecting the operation of the drilling machine and the drill rod, especially causing a great degree of wear on the drill rod, affecting its service life.

[0040] See also Figures 1 to 7 As shown, in order to collect the dust and debris generated by the drill rod 1 during the drilling process and achieve continuous discharge, the accumulation of dust and debris is avoided, and the protection performance of the drill rod 1 is improved.

[0041] The dust and slag removal unit includes a shield 2, a sleeve 4, a transmission structure 5 and a material stripper plate 6. The shield 2 is a hemispherical groove structure, and the shield 2 is fixed to the frame, and a discharge port 3 is provided on the side wall of the shield 2; the axis of the sleeve 4 coincides with that of the shield 2, one end of the sleeve 4 is inserted on the bottom wall of the shield 2 and the two are rotatably connected, and the drill rod 1 is inserted through the sleeve 4; the transmission structure 5 is arranged between the inner wall of the sleeve 4 and the side wall of the drill rod 1, and the transmission assembly is used to drive the sleeve 4 to rotate during the feeding process of the drill rod 1; the material stripper plate 6 is fixedly connected to the sleeve 4, and the material stripper plate 6 is used to rotate in the shield 2 driven by the sleeve 4, so as to realize the continuous discharge of dust and debris collected in the shield 2 from the discharge port 3.

[0042] Among them, see Figure 4 and Figure 5As shown, the driving part 12 includes a first motor, whose output shaft is detachably connected to the drill rod 1 through a coupling. The feeding part 13 includes a moving plate 131, a second motor 132, a stud 133 and a bearing. The moving plate 131 is slidably connected to a matching slide groove on the frame. The first motor is fixed on the moving plate 131, and the moving direction of the moving plate 131 is parallel to the axis of the drill rod 1. One end of the stud 133 is rotatably connected to the anti-blocking cover 2 through a bearing, and the other end is connected to the output shaft of the second motor 132 through a coupling, and the second motor 132 is fixed to the frame. The device also includes a moving base, a lifting mechanism, a steering mechanism and a slag storage box (not shown in the figure). The lifting mechanism is installed on the mobile base, the steering mechanism is installed on the mobile end of the lifting base, and then the frame is fixed as a whole on the rotating end of the steering mechanism, and the slag storage box is connected to the discharge port 3 on the protective cover 2 through a transmission pipeline, so that during the drilling process, the mobile base is used to facilitate the overall movement of the device to the position where the hole needs to be drilled, the drilling height of the drill rod 1 can be adjusted by the lifting mechanism, the drilling angle of the drill rod 1 can be adjusted by the steering mechanism, and the slag storage box can be used to collect the slag and dust discharged from the discharge port 3 for easy processing. And the drill rod 1 preferably used in this device is mainly a threaded drill. Through the threaded structure of the threaded drill, during the drilling process, no matter how the drilling angle of the drill rod 1 changes, the slag can be fully guided into the protective cover 2 through the thread on the drill rod 1, so that the material removal plate 6 can fully push the slag out of the discharge port 3.

[0043] See also Figures 1 to 5 As shown, specifically, when the device is used, the drilling direction of the drill rod 1 is adjusted, and the protective cover 2 is moved so that the opening of the protective cover 2 is completely in contact with the surrounding side of the desired drilling position, and the drilling position is completely enclosed and sealed, and then the driving part 12 and the feeding part 13 are started, and the driving part 12 and the feeding part 13 work together to make the drill rod 1 rotate and feed to achieve drilling, and under the action of the protective cover 2, the dust and debris generated during the drilling process will be completely blocked and collected inside the protective cover 2, and at the same time, the rotation of the drill rod 1 is transmitted through the transmission structure 5. The cooperation drives the sleeve 4 to rotate, and then the sleeve 4 drives the material stripping plate 6 to rotate. The material stripping plate 6 rotates in the protective cover 2 to continuously push the dust and debris generated during the drilling of the drill rod 1 to the discharge port 3 of the protective cover 2, so as to continuously remove the debris and dust in the protective cover 2, thereby effectively avoiding the accumulation of debris and dust in the protective cover 2, that is, avoiding the wear and damage to the drill rod 1 caused by the accumulation of debris and dust around the drill rod 1, effectively improving the protection performance of the drill rod 1, and can extend the service life of the drill rod 1.

[0044] See also Figure 3As shown, further, in order to ensure that the drill rod 1 can maintain the continuous rotation of the material stripper plate 6 during the moving feeding process, the debris and dust in the protective cover 2 can be effectively discharged to avoid accumulation and wear and damage to the drill rod 1. The transmission structure 5 of the device includes a guide slot 51 along the axial direction of the sleeve 4 and opened on the inner wall of the sleeve 4, and a transmission block 52 sliding in the guide slot 51, and one end of the transmission block 52 extending out of the guide slot 51 is fixedly connected to the side wall of the drill rod 1. Preferably, the transmission block 52 is fixed on the side of the drill rod 1 close to the driving part 12. At the same time, in order to ensure the stability of the cooperation between the drill rod 1 and the sleeve 4, at least two groups of guide slots 51 and transmission blocks 52 are provided according to actual applications. Thus, when in use, the feed part 13 pushes the drill rod 1 to move along the axial direction while always keeping the transmission block 52 moving in the guide slot 51 on the inner wall of the sleeve 4, and the rotation of the drill rod 1 is coordinated with the transmission block 52 and the guide slot 51, so that the sleeve 4 can continue to rotate with the rotation of the drill rod 1 during the movement and feeding process of the drill rod 1, and then the continuous rotation of the material stripper plate 6 is realized, and the debris and dust collected in the shield 2 can be continuously cleaned during the drilling process of the drill rod 1. In addition, the transmission structure 5 composed of the guide slot 51 and the transmission block 52 can effectively utilize the power of the drill rod 1, save resources, and has a simple structure.

[0045] See also Figure 2 and Figure 3 As shown, further, in order to ensure that the drill rod 1 can maintain the continuous rotation of the material-dispensing plate 6 during the moving and feeding process, the debris and dust in the shield 2 can be effectively discharged to avoid accumulation and wear and damage to the drill rod 1. A boss 7 is also arranged in the shield 2, and the boss 7 is mounted on the sleeve 4. The side of the boss 7 facing the opening of the shield 2 is a circular arc surface, and the side of the boss 7 away from the circular arc surface is fitted and fixedly connected with the side wall of the shield 2, and the side of the material-dispensing plate 6 close to the boss 7 is fitted with the circular arc surface of the boss 7. When in use, the arrangement of the boss 7 can first be used to seal and block the connection gap between the sleeve 4 and the shield 2 to prevent dust and debris from entering the gap and causing obstacles to the rotation of the sleeve 4, and then the circular arc surface of the boss 7 facing the opening of the shield 2 can effectively guide the collected debris and dust to a position away from the drill rod 1, so that the material-dispensing plate 6 can fully push the debris and dust out of the discharge port 3.

[0046] See also Figures 3 to 6 As shown, further, in order to ensure that the drill rod 1 can maintain the continuous rotation of the material stripper plate 6 during the moving feeding process, the debris and dust in the shield 2 can be effectively discharged to avoid accumulation and wear and damage to the drill rod 1. The opening edge of the shield 2 is covered with an annular sealing sleeve 8, and a plurality of elastic components 9 are evenly distributed between the outer wall of the annular sealing sleeve 8 and the outer wall of the shield 2. The elastic components 9 are used to strengthen the adhesion between the sealing sleeve and the side wall of the tunnel. Figure 6As shown, a preferred elastic component 9 includes a first connecting plate 91, a second connecting plate 92, a guide column 93 and a spring 94. The first connecting plate 91 is fixedly connected to the side wall of the sealing sleeve, and a through hole is provided on the first connecting plate 91; the second connecting plate 92 is fixedly connected to the side wall of the shield 2, and the first connecting plate 91 and the second connecting plate 92 are arranged opposite to each other; one end of the guide column 93 is fixedly connected to the second connecting plate 92, and the other end is arranged through the through hole on the first connecting plate 91; the spring 94 is sleeved on the guide column 93, and the spring 94 is located between the first connecting plate 91 and the second connecting plate 92 and is fixedly connected to both of them. When in use, the open end of the shield 2 is moved and adjusted to abut against the side wall of the tunnel through the sealing sleeve. However, during the drilling process of the drill rod 1, the device will generate its own mechanical vibration. At this time, the cooperation between the sealing sleeve and the elastic component 9 not only changes the rigid contact between the shield 2 and the tunnel side wall, causing damage to the pulley of the shield 2 during the vibration process, but also during the mechanical vibration process, when a gap is generated between the shield 2 and the tunnel side wall, the elastic reset effect of the spring 94 is utilized to enable the sealing sleeve to always maintain the basic effect with the tunnel side wall, thereby effectively filling the possible gap and effectively blocking dust and debris in the shield 2, which is convenient for centralized cleaning, thereby effectively preventing dust from drifting into the drill rod 1, the drive part 12, the feed part 13 and other loading and unloading structures to cause damage to the device, and also preventing dust from drifting and causing physical harm to construction personnel.

[0047] See also Figure 3 and Figure 7 As shown, further, in order to avoid the wear and damage of the drill rod 1 caused by the accumulation of debris and dust, and to improve the protection performance of the drill rod 1, the sealing sleeve is also fixedly connected to the side wall on the inner side of the shield 2 with an annular guide seat 10, and the side wall of the guide seat 10 facing the drill rod 1 is inclined, and the lower end of the inclined direction is away from the drill rod 1, and the upper end of the inclined direction is close to the drill rod 1 and is flush with the upper side wall of the sealing sleeve. When in use, the debris and dust that fall on the edge of the protective cover 2 can be guided by the inclined surface of the guide seat 10 to the inside of the protective cover 2 at all times, especially when the drill rod 1 is drilling a hole in the tunnel side wall horizontally or at a small angle. The debris generated at this time is basically on the lower side of the drill rod 1. If the guide seat 10 is not set, a part of the debris may remain on the edge of the protective cover 2 and cannot be cleaned up by the material removal plate 6. The guide seat 10 can effectively guide this part of the debris to a position where the material removal plate 6 is easy to carry, so that the debris can be well cleaned out from the discharge port 3 to avoid the accumulation of debris.

[0048] See also Figures 2 to 5As shown, further, in order to ensure that the drill rod 1 can maintain the continuous rotation of the material plate 6 during the moving and feeding process, the debris and dust in the protective cover 2 can be effectively discharged to avoid accumulation and wear and damage to the drill rod 1. A high-resilience cushion 11 is also fixed to the sealing cover, and the cushion 11 surrounds the edge of the opening of the protective cover 2. The preferred cushion 11 can be made of a high-elastic sponge material. The high-elastic cushion 11 can enable the protective cover 2 to be constructed at different inclined positions of the tunnel, ensuring that the opening of the protective cover 2 is fully in contact and sealed with the side wall of the tunnel, so that the debris and dust can be thoroughly cleaned, and at the same time, it has a good dustproof effect.

[0049] See also Figure 2 As shown, further, in order to avoid the wear and damage of the drill rod 1 caused by the accumulation of debris and dust, and to improve the protection performance of the drill rod 1, the lower end of the discharge port 3 is connected to the boss 7, and the upper end is connected to the guide seat 10. When in use, the accumulated debris and dust can be fully pushed out of the discharge port 3 by the rotation of the material stripping plate 6, avoiding the residual accumulation of debris and dust.

[0050] See also Figure 3 As shown, further, in order to improve the protection performance of the drill rod 1. The upper end of the sleeve 4 is flush with the opening of the shield 2. At the same time, the end of the material-pickup plate 6 away from the boss 7 is flush with the opening of the shield 2, and the side of the material-pickup plate 6 away from the sleeve 4 is in contact with the inner wall of the shield 2. Therefore, when in use, the sleeve 4 can achieve good sealing protection for the entire rotation and movement of the drill rod 1, effectively preventing the drill rod 1 from contacting with the debris and dust in the shield 2, and at the same time, the design of the material-pickup plate 6 can fully discharge the collected debris and dust from the discharge port 3 during rotation, so that the use effect is better and the protection performance of the drill rod 1 is better.

[0051] Working principle of this device:

[0052] When drilling, the mobile base is used to facilitate the overall movement of the device to the position where the hole is required to be drilled, the lifting mechanism can be used to adjust the drilling height of the drill rod 1, and the steering mechanism can be used to adjust the drilling angle of the drill rod 1. After adjusting the drilling direction of the drill rod 1, the position of the device is adjusted to move the protective cover 2 so that the opening of the protective cover 2 is completely in contact with the surrounding side of the desired drilling position, and the drilling position is completely enclosed and sealed, and then the driving part 12 and the feeding part 13 are started, and the driving part 12 and the feeding part 13 work together to rotate the drill rod 1 into the hole. Drilling is realized, and under the action of the protective cover 2, all dust and debris generated during the drilling process will be blocked and collected inside the protective cover 2. At the same time, the rotation of the drill rod 1 drives the sleeve 4 to rotate through the cooperation of the transmission structure 5, and then the sleeve 4 drives the material-diverting plate 6 to rotate. The dust and debris generated during the drilling process of the drill rod 1 are continuously pushed to the discharge port 3 of the protective cover 2 through the rotation of the material-diverting plate 6 in the protective cover 2, so that the debris and dust in the protective cover 2 are continuously removed, and the debris and dust discharged from the discharge port 3 can be collected in a centralized manner by using the slag storage box. Therefore, the accumulation of debris and dust in the protective cover 2 can be effectively avoided, that is, the wear and damage to the drill rod 1 caused by the accumulation of debris and dust around the drill rod 1 is avoided, and the protection performance of the drill rod 1 is effectively improved.

[0053] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
