Description

Technical Field

[0001] This invention relates to the field of borehole auxiliary cleaning technology, specifically to a borehole auxiliary cleaning device for rail transit construction. Background Technology

[0002] In rail transit construction, drilling is a fundamental prerequisite for anchoring, rebar installation, pipeline pre-laying, and equipment installation. After drilling, a large amount of concrete debris, dust, and gravel particles generated by impact or rotary drilling remain inside the hole. If these debris are not removed promptly, they will directly affect the bonding effect of the anchoring agent and the anchoring force of the rebar, thereby weakening the reliability of the structural connection. Currently, the following traditional methods are mainly used to clean the debris inside the borehole at construction sites: first, using a high-pressure air gun to blow air into the hole to blow the debris out; second, manually digging with a brush or debris removal tool; and third, using a simple vacuum cleaner with a thin suction tube for suction. In some work sites, cotton yarn or sponges soaked in solvent are used for secondary wiping after cleaning the hole to ensure the hole wall is clean.

[0003] However, existing borehole cleaning methods have many shortcomings in practical applications. First, high-pressure air guns cause debris and dust to fly out of the hole at high speed, not only causing dust pollution at the construction site and affecting the working environment, but also potentially injuring operators and surrounding equipment. Furthermore, the debris scattered on the ground requires secondary cleaning, increasing the workload. Second, brush digging and simple vacuum cleaners are only suitable for shallow holes or large-diameter boreholes. For long and narrow boreholes with a large depth, the tools cannot reach the bottom of the hole, resulting in unsatisfactory cleaning effects. Summary of the Invention

[0012] Preferably, a second fixed cylinder extends through the bottom surface of the inner cavity of the dust collection box. The second fixed cylinder is located directly below the first fixed cylinder. A third rolling bearing is fixedly installed on the inner wall of the second fixed cylinder. A vent plate is fixedly installed on the inner surface of the inner ring of the third rolling bearing. The bottom end of the rotating rod is fixedly installed on the upper surface of the vent plate.

[0015] This invention provides an auxiliary cleaning device for drilling holes in rail transit construction. It has the following beneficial effects: I. This auxiliary cleaning device for drilling in rail transit construction, by setting up a collection mechanism, can apply a rotational driving force during operation, and cooperate with the dust collection mechanism to generate suction, and then collect the debris cleaned from the borehole.

[0016] II. The auxiliary cleaning device for drilling in rail transit construction, by setting up a dust suction mechanism, can cooperate with the collection mechanism to wrap the area of ​​the borehole wall that needs to be cleaned, scrape off the loose slag from the borehole wall, and then use the generated negative pressure to suck the debris in the borehole into the transfer unit. Finally, the airflow is used to pump the slag sucked into the transfer unit into the interior of the collection mechanism.

[0017] Third, this auxiliary cleaning device for drilling in rail transit construction uses a hydraulic telescopic rod to drive the extension and retraction of the moving rod, controlling the position of the collection mechanism and the dust suction mechanism in the borehole. This allows for gradual cleaning of the borehole walls in different areas during drilling, preventing debris from splashing. At the same time, the controllable extension and retraction of the hydraulic telescopic rod enables the device to adapt to the cleaning needs of boreholes at different depths.

[0018] IV. This auxiliary cleaning device for drilling in rail transit construction utilizes an isolation net. When airflow containing debris enters the collection cylinder, the air is discharged through the net, while the debris is intercepted and retained within the cylinder. The mesh diameter of the isolation net is smaller than the minimum diameter of the debris, ensuring effective interception. An internal threaded ring and a sealing cap are used to discharge accumulated debris from the collection cylinder after the device has cleaned the borehole. The sealing cap can be unscrewed to clean the collection cylinder; after cleaning, the cap is tightened to restore a seal, ensuring no air leakage from the bottom during dust collection.

[0019] V. This auxiliary cleaning device for drilling in rail transit construction utilizes a rotating disc that rotates with a rotating rod. Air jets on the disc's surface guide air from the inner cavity of the dust collection box into the borehole. These jets extend from the upper surface to the outer surface of the rotating disc, causing the airflow to be ejected radially to clean the bottom of the borehole. An arc-shaped sealing disc, in frictional engagement with the upper surface of the rotating disc, closes the jets when they reach the disc and opens them when they move away, ensuring that only the side of the rotating disc closest to the collection cylinder emits air.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0023] like Figures 1-2 As shown, this invention provides a technical solution: an auxiliary cleaning device for drilling in rail transit construction, comprising a frame 1 and a cylinder 7, and a first handle 2 and a second handle 3 fixed to the outer surface of the frame 1. The cylinder 7 serves as an internal channel for the cleaning device, used for insertion into the borehole. Simultaneously, an adhesive extrusion device can be added inside the cylinder 7 to inject adhesive into the borehole after the slag on the borehole wall has been cleaned. The first handle 2 and the second handle 3 are provided for the operator to hold with both hands to maintain the stability of the device. The optimized distribution of the two handles allows the operator to balance the weight of the device during handheld operation, reducing operator fatigue. It also ensures that the entire device does not shake during handheld operation. The device further includes: A hydraulic telescopic rod 4 is fixedly installed on the inner wall of the frame 1, and a moving rod 10 is fixedly installed at the output end of the hydraulic telescopic rod 4. By setting the hydraulic telescopic rod 4, the moving rod 10 is driven to extend and retract, thereby controlling the position of the collecting mechanism 8 and the dust suction mechanism 9 in the borehole. This allows for the gradual cleaning of the borehole wall in different areas during borehole cleaning, preventing debris from splashing. At the same time, the controllable extension and retraction of the hydraulic telescopic rod 4 enables the device to adapt to the cleaning needs of boreholes at different depths. The end of frame 1 furthest from the second grip 3 passes through a limiting tube 5. A moving rod 10 is slidably connected to the inner cavity of the limiting tube 5. A hexagonal rod 6 is fixed to one end of the moving rod 10 located in the limiting tube 5, and the end of the hexagonal rod 6 furthest from the moving rod 10 is fixed to the top of the cylinder 7. The limiting tube 5 provides linear motion guidance for the moving rod 10 and the hexagonal rod 6. The hexagonal cross-section of the inner wall of the limiting tube 5 ensures that the moving rod 10 and the hexagonal rod 6 do not deviate when sliding within it, ensuring that the cylinder 7 can move accurately along the drilling axis. The hexagonal rod 6, with its hexagonal cross-section matching the hexagonal hole in the inner cavity of the limiting tube 5, prevents the cylinder 7 from rotating in the borehole, ensuring stable cleaning direction. Simultaneously, it smoothly transmits the thrust of the hydraulic telescopic rod 4 to the cylinder 7, allowing the cylinder 7 to reach any depth position in the borehole.

[0024] like Figures 3-10As shown, the auxiliary cleaning device for drilling in rail transit construction also includes a collection mechanism 8, which is used to collect debris inside the borehole. The collection mechanism 8 is located on the outer surface of the cylinder 7. By setting the collection mechanism 8, a rotational driving force can be applied during operation, and it cooperates with the dust collection mechanism 9 to generate suction, thereby collecting the debris cleaned from the borehole. The collecting mechanism 8 includes a collecting cylinder 81, which is fixed to the outer surface of the cylinder 7. A first rolling bearing 87 is fixed to the middle of the outer surface of the collecting cylinder 81. A rotating ring 88 is fixed to the outer surface of the outer ring of the first rolling bearing 87, and a first gear 89 is fixed to the outer surface of the rotating ring 88. By setting the collecting cylinder 81 as a storage container for debris, the volume of the collecting cylinder 81 is designed to accommodate all the debris generated in one drilling operation, avoiding frequent debris discharge. By setting the first rolling bearing 87, the rotating ring 88 can rotate freely relative to the collecting cylinder 81, converting the sliding friction between the rotating ring 88 and the collecting cylinder 81 into rolling friction, reducing rotational resistance, and ultimately improving transmission efficiency and service life. A dust collection mechanism 9 is used to guide debris from inside the borehole to the collection mechanism 8. The dust collection mechanism 9 is fitted onto the outer surface of the collection mechanism 8. By providing the dust collection mechanism 9, it can cooperate with the collection mechanism 8 to cover the area of ​​the borehole wall that needs to be cleaned, scrape off the loose debris from the borehole wall, and then use the generated negative pressure to suck the debris from the borehole into the transfer section. Finally, airflow is used to draw the debris sucked into the transfer section back into the collection mechanism 8. The vacuuming mechanism 9 includes a vacuum chamber 91, which is fixed to the outer surface of the collection cylinder 81. A rotating ring 88 and a first gear 89 are rotatably connected to the inner cavity of the vacuum chamber 91. By setting the vacuum chamber 91 and fixing it to the outer surface of the collection cylinder 81, it serves as the outer shell of the vacuuming mechanism 9. The rotating ring 88 and the first gear 89 are housed inside the vacuum chamber 91, and the vacuum chamber 91 also provides protection for the internal rotating parts, preventing debris from entering the bearing area and causing jamming.

[0025] Several evenly distributed isolation nets 82 penetrate the top of the outer surface of the collection cylinder 81, and an internally threaded ring 811 passes through the middle of the outer surface of the collection cylinder 81. A sealing cap 812 is threadedly connected to the inner cavity of the internally threaded ring 811. By setting up the isolation nets 82, when the airflow containing debris enters the collection cylinder 81, the air is discharged through the isolation nets 82, while the debris is intercepted and retained in the collection cylinder 81. The mesh diameter of the isolation nets 82 is smaller than the diameter of the smallest debris, ensuring the interception effect. By setting up the internally threaded ring 811 and the sealing cap 812, the debris accumulated in the collection cylinder 81 is discharged after the device has cleaned the slag inside the borehole. The sealing cap 812 can be unscrewed to clean the collection cylinder 81. After cleaning, the sealing cap 812 is tightened to restore the seal, ensuring that the dust collection mechanism 9 does not leak air from the bottom when it is working.

[0026] A packaging box 83 is fixed to the outer surface of the collection cylinder 81, and the packaging box 83 is fixed to the upper surface of the dust collection box 91. A fixing frame 84 is fixed to the outer surface of the collection cylinder 81, and the packaging box 83 is fitted onto the outer surface of the fixing frame 84. A stepper motor 85 is fixed to the inner wall of the fixing frame 84. A second gear 86 is mounted on the output end of the stepper motor 85 through a coupling. A bevel gear 810 is fixed to the upper surface of the rotating ring 88, and the second gear 86 meshes with the bevel gear 810. By setting up the packaging box 83, the stepper motor 85 is completely enclosed inside, preventing debris and dust from entering the motor and causing damage. By setting up the stepper motor 85 to drive the second gear 86 to rotate, the speed and direction of the stepper motor 85 can be precisely controlled, thereby precisely adjusting the speed of the rotating rod 96 and controlling the suction power. By setting a bevel gear 810, which is fixed on the upper surface of the rotating ring 88 and meshes with the second gear 86, the rotating ring 88 is made to rotate in the horizontal plane, thereby driving the vacuuming mechanism 9 to start working.

[0027] A gasket 92 is fixed to the outer surface of the dust collection box 91. This gasket 92 is used to contact the wall of the drilled hole. Several annularly distributed circular holes are opened on the upper surface of the dust collection box 91. A vent ring 93 is fixed at each of the circular holes on the upper surface of the dust collection box 91, and a first fixing cylinder 94 is fixed to the inner ring of the vent ring 93. By setting the gasket 92, when the dust collection box 91 is placed into the drilled hole, the gasket 92 contacts the drilled hole wall to form a seal, preventing debris from leaking from the gap between the dust collection box 91 and the hole wall. At the same time, the gasket 92 is made of flexible material, which can adapt to the slight differences of drill holes of different diameters, ensuring the sealing effect and making the cleaning area a closed space to prevent debris from leaking out. By setting the vent ring 93 and the first fixing cylinder 94, air is allowed to be discharged from the inner cavity of the dust collection box 91. The circular holes of the vent ring 93 are aligned with the circular holes on the upper surface of the dust collection box 91 to form a complete airflow channel.

[0028] A second rolling bearing 95 is fixed to the inner wall of the first fixed cylinder 94. A rotating rod 96 is fixed to the inner surface of the inner ring of the second rolling bearing 95, extending to the bottom of the inner cavity of the dust collection box 91. A third gear 97 is fixed to the outer surface of the rotating rod 96, meshing with the first gear 89. By setting the second rolling bearing 95, the rotating rod 96 can rotate smoothly within the first fixed cylinder 94. By setting the rotating rod 96 to rotate within the inner cavity of the dust collection box 91, power is transmitted from the top to the bottom. By setting the third gear 97, fixed to the outer surface of the rotating rod 96 and meshing with the first gear 89, the rotational power of the rotating ring 88 is transmitted to the rotating rod 96, causing the rotating rod 96 to rotate synchronously with the rotating ring 88.

[0029] Connecting discs 98 are fixed to the top and bottom of the outer surface of the rotating rod 96. Each connecting disc 98 has several vent holes on its surface, and a spiral blade 99 is fixed between the opposing surfaces of two connecting discs 98. The connecting discs 98 connect the rotating rod 96 and the spiral blade 99. The vent holes on their surfaces allow air to pass through, ensuring smooth airflow through the connecting discs 98 without air resistance when the spiral blade 99 rotates. The spiral blade 99 generates axial airflow as the rotating rod 96 rotates, creating negative pressure inside the dust collection box 91. This draws air from the inner cavity of the packaging box 83 into the dust collection box 91. Ventilation grooves are spaced between the packaging box 83 and the collection cylinder 81, allowing air to enter the packaging box 83 while preventing debris from entering. The spiral angle of the spiral blade 99 is optimized to ensure sufficient airflow without generating excessive rotational resistance.

[0030] A second fixed cylinder 910 extends through the bottom surface of the inner cavity of the dust collection box 91. This second fixed cylinder 910 is located directly below the first fixed cylinder 94. A third rolling bearing 911 is fixed to the inner wall of the second fixed cylinder 910. An air vent 912 is fixed to the inner surface of the inner ring of the third rolling bearing 911. The bottom end of the rotating rod 96 is fixed to the upper surface of the air vent 912. The second fixed cylinder 910 provides a mounting base for the third rolling bearing 911. The second fixed cylinder 910 and the first fixed cylinder 94 are coaxially aligned, ensuring that the rotating rod 96 maintains coaxiality during rotation and preventing eccentric vibration. The third rolling bearing 911 supports the air vent 912, allowing it to rotate smoothly within the second fixed cylinder 910 and ensuring synchronous rotation between the air vent 912 and the rotating rod 96. The air vent 912 rotates with the rotating rod 96, allowing air to pass through its surface while simultaneously transmitting the rotational motion of the rotating rod 96 to the rotating disk 913.

[0031] A rotating disk 913 is fixedly mounted on the lower surface of the venting disk 912. Several annularly distributed air jet holes 914 are formed on the upper surface of the rotating disk 913, extending from its upper surface to its outer surface. A connecting frame 916 is fixedly mounted on the lower surface of the second fixed cylinder 910. An arc-shaped sealing disk 917 is fixedly mounted at the bottom end of the connecting frame 916, frictionally fitting with the upper surface of the rotating disk 913. By mounting the rotating disk 913, which rotates with the rotating rod 96, the air jet holes 914 on its surface guide air from the inner cavity of the dust collection box 91 into the borehole. The air jet holes 914 extend from the upper surface of the rotating disk 913 to its outer surface, causing the airflow to be ejected radially, thus cleaning the bottom of the borehole. By setting an arc-shaped sealing disc 917, which frictionally engages with the upper surface of the rotating disc 913, the jet hole 914 is closed when it rotates to the position of the arc-shaped sealing disc 917 and opens when it moves away from the arc-shaped sealing disc 917, so that only the rotating disc 913 on the side close to the collecting cylinder 81 will blow out gas.

[0032] A connecting box 813 is fixedly installed at the bottom of the collecting cylinder 81 and the cylinder 7. The inner cavity of the connecting box 813 is connected to the cavity formed by the cylinder 7 and the collecting cylinder 81. Several annularly distributed elastic scrapers 915 are fixedly installed on the outer surface of the rotating disk 913. The elastic scrapers 915 are rotatably connected to the inner surface of the connecting box 813. A sealing frame 814 is fixedly installed on the lower surface of the connecting box 813. The sealing frame 814 cooperates with the gasket 92 to form the area to be cleaned. By setting the connecting box 813 to connect the bottom of the collecting cylinder 81 and the cylinder 7, a channel is formed for debris to enter the collecting cylinder 81. The inner cavity of the connecting box 813 guides the debris sucked in from the bottom of the cylinder 7 into the inside of the collecting cylinder 81, ensuring a smooth airflow path. By setting an elastic scraper 915, which rotates with the rotating disk 913 and rotates on the inner surface of the connecting box 813, the elastic scraper 915 is made of a material with a certain degree of elasticity, which can closely fit the inner surface of the connecting box 813 and scrape off the debris attached to the inner wall of the connecting box 813, preventing debris from accumulating and clogging in the channel and ensuring the smooth flow of the cleaning channel. At the same time, the elasticity of the elastic scraper 915 allows it to deform and pass through when it encounters larger debris, without causing jamming. The scraped debris will also temporarily adhere to the outer surface of the elastic scraper 915. When the airflow is generated by the air jet hole 914 of the rotating disk 913, the debris is blown into the inner cavity of the connecting box 813.

[0033] Working principle: During use, the operator holds the first handle 2 and the second handle 3 with both hands and places the device into the pre-drilled hole. The cylinder 7 first enters the borehole, leaving a gap between its outer surface and the borehole wall as an airflow channel. The gasket 92 and sealing frame 814 on the outer surface of the dust collection box 91 elastically contact the borehole wall to form a seal, enclosing the area to be cleaned as a closed space and preventing debris from leaking out from the gaps. The hydraulic telescopic rod 4 drives the moving rod 10 and the hexagonal rod 6 to extend downward along the limiting tube 5, allowing the device to reach any depth position in the borehole.

[0034] Stepper motor 85 starts, driving bevel gear 810 and rotating ring 88 to rotate via second gear 86. First gear 89 and third gear 97 on the outer surface of rotating ring 88 mesh, transmitting power to rotating rod 96, causing it to rotate at high speed within the dust collection box 91. Rotating rod 96 drives spiral blade 99 to rotate, generating downward airflow within the dust collection box 91. Simultaneously, rotating rod 96 transmits power to rotating disk 913 at the bottom. Rotating disk 913 rotates with rotating rod 96, and its surface air jet holes 914 guide air from the dust collection box 91 to the bottom of the borehole. Because the arc-shaped sealing disk 917 remains stationary on the lower surface of the second fixed cylinder 910, the elastic scraper 915 is not blown away by the airflow when in contact with the borehole wall. When it leaves, it opens, blowing the debris adhering to the surface of the elastic scraper 915 into the inner cavity of connecting box 813, ultimately allowing the debris to enter the collection cylinder 81 with the airflow.

[0035] During the cleaning process, the hydraulic telescopic rod 4 gradually retracts, allowing the device to be pulled out of the borehole section by section to clean different areas of the borehole wall. After cleaning, the stepper motor 85 is turned off, the sealing cover 812 is unscrewed, and the accumulated debris in the collection cylinder 81 is discharged. A glue extrusion device can be added inside the cylinder 7 to inject glue into the borehole after the debris on the borehole wall has been cleaned, realizing an integrated cleaning and grouting operation.
