Description

Technical Field

[0001] This invention relates to the field of rebar installation hole cleaning tools, and in particular to an integrated hole cleaning tool for rebar installation that features anti-diffusion automatic dust removal. Background Technology

[0002] Rebar anchoring, also known as rebar installation, is a post-anchoring connection technique for reinforcing steel bars in seismic reinforcement projects. It utilizes the locking force of structural adhesive to achieve the desired bond strength. It is the optimal choice for structural reinforcement and heavy-load fastening applications. The typical rebar anchoring process involves: marking the location → drilling → cleaning the hole → applying adhesive → installing the rebar → curing → pull-out test (sampling inspection) → tying the rebar and pouring concrete. Therefore, hole cleaning is a crucial step before adhesive injection and rebar installation. Failure to effectively clean the hole will result in poor adhesive injection and rebar installation, failing to meet the required strength standards.

[0003] Chinese Utility Model Patent Publication No. CN215844442U discloses a tool for cleaning holes in planting rebar. The tool includes a cylindrical brush body, a vacuum hose connector, a rotary power device, and a vacuum cleaner. The cylindrical brush body is evenly distributed with brush bristles and vacuum holes. A bracket connecting to a rotating shaft is fixed inside the cylindrical brush body. A through hole is provided between the bracket and the inner wall of the cylindrical brush body to guide the top, bottom, and vacuum holes of the cylindrical brush body. One end of the vacuum hose connector has a sleeve that fits and communicates with the top of the cylindrical brush body, and the fitting part is clearance-fitted with the cylindrical brush body. The sleeve has a shaft hole for the rotating shaft to pass through. One end of the rotating shaft extends out of the sleeve to form a shaft connection end, and is shaft-connected to the rotary power device through the shaft connection end. The other end of the vacuum hose connector has a connection port with a locking clamp, which locks and connects to the vacuum cleaner head. The above structure, by driving the cylindrical brush body to rotate and clean the anchor holes, simultaneously turns on the vacuum cleaner to achieve effective dust removal. This makes it less likely to generate dust during the hole cleaning process, resulting in better cleaning effect and higher efficiency.

[0004] The aforementioned hole cleaning tool uses a cylindrical brush body with suction holes arranged on the cylindrical brush body to clean the rebar holes. However, the diameter of the cylindrical brush body is generally fixed and cannot be adjusted. When cleaning rebar holes with a diameter larger than the cylindrical brush body, the brush on the cylindrical brush body may not be able to reach the hole or may only make slight contact with the inner wall of the hole, which will affect the cleaning of the hole by the cylindrical brush body.

[0005] Therefore, this application provides an integrated hole cleaning tool for rebar installation that features automatic dust removal and anti-diffusion to meet the requirements. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide an integrated anti-diffusion automatic dust removal hole cleaning tool for rebar installation, in order to solve the problem that when it is necessary to clean the rebar holes with a diameter larger than that of the cylindrical brush body, the brush on the cylindrical brush body may not be able to make contact or the brush may only make slight contact with the inner wall of the hole, which will affect the cleaning of the hole by the cylindrical brush body.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0008] A hole cleaning tool for rebar installation with anti-diffusion automatic dust removal, including a main body and a piston base fixed at the bottom of the main body. A rotating changing ring is rotatably connected at the center of the piston base, and a dust suction mechanism is provided inside the main body.

[0009] The top of the main body is equipped with a control mechanism for controlling the rotation of the vacuuming mechanism, and the control mechanism includes a handle fixed to the top of the main body;

[0010] The vacuuming mechanism includes a rotating shaft cylinder rotatably connected inside the handle, a fitting tube slidably connected inside the rotating shaft cylinder, a first vacuum tube fixedly connected to the bottom of the fitting tube, and a connecting thread provided on the outer wall of the first vacuum tube near the fitting tube.

[0011] The scraping mechanism is detachably installed on the outer wall of the first suction pipe. The scraping mechanism includes a threaded connecting cylinder that is threaded onto the connecting thread, and multiple elastic scraping strips are fixedly connected to the bottom of the threaded connecting cylinder.

[0012] Optionally, the outer wall of the main body is provided with multiple adjusting sliding holes, and the number of adjusting sliding holes corresponds to the number of elastic scrapers.

[0013] Optionally, the piston bottom outer wall is provided with an anti-diffusion mechanism, which includes an adjusting piston cylinder that is slidably connected to the piston bottom outer wall, a rubber cover that is fixedly connected to the bottom of the adjusting piston cylinder, and a second suction pipe connector that is fixedly connected to one end of the adjusting piston cylinder outer wall near the rubber cover.

[0014] Optionally, multiple positioning support strips are fixedly connected to the outer wall of the rubber cover. One of the positioning support strips has a threaded hole at the end of its outer wall away from the rubber cover. The other positioning support strips have a sliding connecting block fixedly connected to the end away from the rubber cover. The sliding connecting block is slidably connected to the adjusting sliding hole. A clamping bolt knob is slidably connected inside the adjusting sliding hole corresponding to the threaded hole. The clamping bolt knob passes through the adjusting sliding hole and is threadedly connected to the threaded hole.

[0015] Optionally, the elastic scraper is distributed inside the rotating ring, and the outer wall of the elastic scraper abuts against the inner wall of the rotating ring. The elastic scraper is made of wear-resistant elastic material.

[0016] Optionally, the control mechanism also includes a control device fixedly connected to the top of the handle, a motor fixedly connected inside the control device, a control button on the outside of the control device for controlling the start and stop of the motor, and a drive pulley at the output end of the motor.

[0017] Optionally, a pulley is fixedly connected to the outer wall of the rotating shaft cylinder, and a belt is sleeved between the drive pulley at the motor output end and the pulley on the rotating shaft cylinder. The outer wall of the fitting tube is polygonal, and the fitting tube slides through the rotating shaft cylinder.

[0018] Optionally, a first dust collection cylinder is fixedly connected to the top of the fitting tube, and a rotating connector is rotatably connected to the top of the first dust collection cylinder. The rotating connector is externally connected to a first suction pipe, and the first dust collection cylinder, the fitting tube, and the first suction pipe are connected in series.

[0019] Optionally, an elliptical elastic expansion tube is fixedly connected to the bottom of the first suction tube. The elliptical elastic expansion tube is made of elastic material, and its outer wall is provided with several cracked holes. A suction tube opening is fixedly connected to the bottom of the elliptical elastic expansion tube.

[0020] Optionally, a tube clamp is fixedly connected to the top of the control device, and a mounting bracket is fixedly connected to the top of the control device. A second dust collection cylinder is inserted inside the mounting bracket. The bottom of the mounting bracket is connected to the second suction pipe connector through a connecting pipe. The top of the second dust collection cylinder is connected to a second suction pipe. The tube clamp is used to constrain the first suction pipe and the second suction pipe.

[0021] Compared with the prior art, the present invention has at least the following beneficial effects:

[0022] In the above solution, by using elastic scrapers instead of traditional brushes, the three elastic scrapers can be bound by a rotating ring before being inserted into the anchoring hole, causing them to contract and press tightly against the first suction pipe. This facilitates insertion into the anchoring hole. After insertion, the three elastic scrapers, no longer bound by the rotating ring, will recover through elastic deformation and press against the anchoring hole wall. The same set of elastic scrapers can be adapted to a certain range of anchoring hole diameters, thus eliminating the need for frequent tool changes. This reduces tool costs and improves the cleaning efficiency of batch anchoring. Furthermore, when the brush diameter is smaller than the hole diameter, this method eliminates the need for manual control of the cleaning tool's brush to approach the inner wall of the anchoring hole and perform circumferential movements within the hole due to mismatch between the brush and the hole diameter, thereby improving the convenience of cleaning anchoring holes with the cleaning tool.

[0023] The flexible scraper rotates on the inner wall of the anchor hole to remove dust. The scraped dust falls to the bottom of the hole, and the suction generated by the suction pipe can draw most of the dust into the first suction pipe and then into the first dust collection cylinder. When the three flexible scrapers expand to a large extent, the bottom of the flexible scrapers will gradually move above the suction pipe opening, so the suction pipe opening will be against the bottom of the hole. As the first suction pipe continues to extend into the hole, until the bottom of the three expanded flexible scrapers is against the bottom of the hole, the elastic elliptical expansion tube will be squeezed. At this time, the multiple cracked holes on the elliptical expansion tube will expand accordingly. At this time, the suction port of the first suction pipe will become a spherical suction port, so that the suction direction covers the bottom, top and sides, further increasing the suction range and improving the suction effect.

[0024] When the rebar hole depth is small, pushing the threaded connecting cylinder near the rotating ring via the fitting tube will lift the entire main body, causing the rubber cover to leave the ground. By rotating the clamping bolt knob, the clamping position of one of the positioning support bars can be released. At this point, two of the positioning support bars can slide through the sliding connecting block inside the adjusting slide hole, making the bottom of the rubber cover fit tightly against the plane of the rebar hole. Then, tightening the clamping bolt knob will reposition it, further improving the applicability of the device. Furthermore, the anti-diffusion mechanism allows the rubber cover to cover the hole surface during cleaning, preventing dust from spreading outwards. Additionally, adjusting the piston cylinder and piston bottom... The sliding connection creates a chamber between the adjusting piston cylinder and the rubber cover, and connects it to the second dust collection cylinder via a connecting pipe. The top of the second dust collection cylinder is connected to a second suction pipe, allowing for simultaneous cleaning of the holes and the interior of the adjusting piston cylinder and rubber cover. This draws dust that has diffused into the rubber cover into the second dust collection cylinder. During this process, the connection between the center of the rotating ring and the interior of the adjusting piston cylinder allows external air to enter the adjusting piston cylinder through the rotating ring, further preventing dust from the rubber cover and the adjusting piston cylinder from diffusing into the external environment and improving the dust diffusion prevention effect.

[0044] Example 1, such as Figures 1 to 10As shown, an embodiment of the present invention provides an integrated anti-diffusion automatic dust removal hole cleaning tool for rebar installation, including a main body 1 and a piston base 102 fixed to the bottom of the main body 1. A rotating ring 103 is rotatably connected to the center of the piston base 102. A dust collection mechanism 5 is provided inside the main body 1. A control mechanism 4 for controlling the rotation of the dust collection mechanism 5 is provided on the top of the main body 1. The control mechanism 4 includes a handle 401 fixed to the top of the main body 1. The dust collection mechanism 5 includes a rotating shaft cylinder 501 rotatably connected inside the handle 401. A fitting tube 502 is slidably connected inside the rotating shaft cylinder 501. A first dust collection tube 503 is fixedly connected to the bottom of the fitting tube 502. Three elastic scrapers 302 close to the first dust collection tube 503 are inserted into the rebar hole along with the first dust collection tube 503 and the dust collection tube opening 506. After the rubber cover 202 contacts the surface of the hole and covers the rebar hole, the fitting tube 502 is pushed to slide inside the rotating shaft cylinder 501, thus cleaning the first dust collection tube 503 and the elliptical elastic scraper. The tension tube 505 and the suction pipe 506 are inserted into the depth of the rebar hole. The control mechanism 4 also includes a control device 402 fixedly connected to the top of the handle 401. A motor 403 is fixedly connected inside the control device 402. A control button is provided on the outside of the control device 402. The control button is used to control the start and stop of the motor 403. A drive pulley is provided at the output end of the motor 403. A pulley is fixedly connected to the outer wall of the rotating shaft 501. A belt is sleeved between the drive pulley at the output end of the motor 403 and the pulley on the rotating shaft 501. The outer wall of the fitting tube 502 is polygonal. The fitting tube 502 slides through the rotating shaft 501. The motor 403 is started by opening the control button on the control device 402. The belt drives the rotating shaft 501 to rotate inside the handle 401, thereby driving the fitting tube 502, the first suction pipe 503 and the scraping mechanism 3 to rotate. The elastic scraper 302 rotates inside the rebar hole and scrapes its inner wall, thereby cleaning the inner wall of the rebar hole.

[0045] The outer wall of the first suction pipe 503 is provided with a connecting thread 504 at one end near the fitting pipe 502. A scraping mechanism 3 is detachably installed on the outer wall of the first suction pipe 503. The scraping mechanism 3 includes a threaded connecting sleeve 301 threadedly connected to the connecting thread 504. The direction in which the threaded connecting sleeve 301 is screwed onto the connecting thread 504 is the same as the direction of rotation of the first suction pipe 503, so as to prevent the threaded connecting sleeve 301 from gradually disengaging from the connecting thread 504 when the scraping mechanism 3 is rotated. Multiple elastic scraper strips 302 are fixedly connected to the bottom of the threaded connecting sleeve 301. The wall is provided with multiple adjusting sliding holes 101, and the number of adjusting sliding holes 101 corresponds to the number of elastic scrapers 302. The elastic scrapers 302 are distributed inside the rotating ring 103, and the outer wall of the elastic scraper 302 abuts against the inner wall of the rotating ring 103. The elastic scrapers 302 are made of wear-resistant elastic material. The three elastic scrapers 302 bound by the rotating ring 103 will gradually recover due to the elastic deformation of the elastic scrapers 302 as the threaded connecting cylinder 301 approaches the rotating ring 103, so that the part of the three elastic scrapers 302 located inside the rebar hole abuts against the inner wall of the rebar hole.

[0046] The outer wall of the piston bottom 102 is provided with an anti-diffusion mechanism 2. The anti-diffusion mechanism 2 includes an adjusting piston cylinder 201 that is slidably connected to the outer wall of the piston bottom 102. A rubber cover 202 is fixedly connected to the bottom of the adjusting piston cylinder 201. A second dust suction pipe connector 204 is fixedly connected to one end of the outer wall of the adjusting piston cylinder 201 near the rubber cover 202. Through the sliding connection between the adjusting piston cylinder 201 and the piston bottom 102, the anti-diffusion mechanism 2 can prevent dust from spreading outward by covering the surface of the hole with the rubber cover 202 during the hole cleaning process. A chamber can be formed between the adjusting piston cylinder 201 and the rubber cover 202. The chamber is connected to the second dust collection cylinder 406 through a connecting pipe via the second dust suction pipe connector 204. A second suction pipe is connected to the top of the second dust collection cylinder 406. Dust can be suctioned into the adjusting piston cylinder 201 and the inside of the rubber cover 202 at the same time as cleaning the hole. Dust that has diffused into the inside of the rubber cover 202 can be sucked into the inside of the second dust collection cylinder 406.

[0047] Multiple positioning support bars 203 are fixedly connected to the outer wall of the rubber cover 202. One of the positioning support bars 203 has a threaded hole 206 at the end of its outer wall away from the rubber cover 202. The other positioning support bars 203 have a sliding connecting block 205 fixedly connected to the end away from the rubber cover 202. The sliding connecting block 205 is slidably connected to the adjusting sliding hole 101. A clamping bolt knob 207 is slidably connected inside the adjusting sliding hole 101 corresponding to the threaded hole 206. The clamping bolt knob 207 passes through the adjusting sliding hole 101 and is threadedly connected to the threaded hole 206. By rotating the clamping bolt knob 207, the clamping and positioning of one of the positioning support bars 203 can be released. At this time, two of the positioning support bars 203 can be pushed to slide inside the adjusting sliding hole 101 through the sliding connecting block 205, so that the bottom of the rubber cover 202 is close to the plane where the anchor hole is located. Then tighten the clamping bolt knob 207 to reposition it.

[0048] A first dust collection cylinder 507 is fixedly connected to the top of the fitting tube 502. A rotating connector 508 is rotatably connected to the top of the first dust collection cylinder 507. A first suction pipe is connected to the outside of the rotating connector 508. The first dust collection cylinder 507, the fitting tube 502, and the first suction pipe 503 are connected in series. A bundled tube clamp 404 is fixedly connected to the top of the control device 402. A mounting bracket 405 is fixedly connected to the top of the control device 402. A second dust collection cylinder 406 is inserted into the mounting bracket 405. The bottom of the mounting bracket 405 is connected to the second suction pipe connector 204 through a connecting pipe. A second suction pipe is connected to the top of the second dust collection cylinder 406. The bundled tube clamp 404 is used to constrain the first suction pipe and the second suction pipe. By setting the bundled tube clamp 404, it is possible to... The suction pipe connected to the top of the second dust collection cylinder 406 and the rotating connector 508 is constrained. By rotating the connector 508 to the first dust collection cylinder 507, the suction pipe can be prevented from rotating synchronously with the first dust collection cylinder 507 and getting tangled. The external suction pipe is connected through the rotating connector 508, which generates suction on the first dust collection cylinder 507, the fitting tube 502, and the first suction pipe 503. The dust scraped off by the elastic scraper 302 inside the anchor hole is sucked into the first dust collection cylinder 507 through the suction pipe opening 506 and the cracked strip hole on the elliptical elastic expansion tube 505. This allows for simultaneous dust suction while disturbing and scraping off the dust remaining on the inner wall of the anchor hole.

[0049] The bottom of the first suction tube 503 is fixedly connected to an elliptical elastic expansion tube 505. The elliptical elastic expansion tube 505 is made of elastic material and has several cracked grooves on its outer wall. The bottom of the elliptical elastic expansion tube 505 is fixedly connected to a suction tube opening 506. As the first suction tube 503 continues to extend into the hole, until the bottom of the three elastic scrapers 302 after unfolding abuts against the bottom of the hole, the elastic elliptical elastic expansion tube 505 will be squeezed. At this time, the multiple cracked grooves on the elliptical elastic expansion tube 505 will expand accordingly. At this time, the suction opening of the first suction tube 503 will become a spherical suction opening, so that the suction direction covers the bottom, top and sides, further improving the suction range.

[0050] The working principle of the technical solution provided by this invention is as follows:

[0051] Three elastic scrapers 302, which are close to the first suction pipe 503, are inserted into the rebar hole along with the first suction pipe 503 and the suction pipe opening 506. After the rubber cover 202 contacts the surface of the hole and covers the rebar hole, the fitting tube 502 is pushed to slide inside the rotating shaft cylinder 501, pushing the first suction pipe 503, the elliptical elastic expansion tube 505, and the suction pipe opening 506 deeper into the rebar hole. The three elastic scrapers 302, which are restrained by the rotating ring 103, will gradually recover their elastic deformation as the threaded connecting cylinder 301 approaches the rotating ring 103, so that the part of the three elastic scrapers 302 located inside the rebar hole abuts against the inner wall of the rebar hole. At this time, the control button on the control device 402 is turned on. The starter motor 403 rotates, driving the rotating shaft 501 to rotate inside the handle 401 via a belt. This, in turn, rotates the fitting tube 502, the first suction tube 503, and the scraping mechanism 3. The elastic scraper 302 rotates inside the anchoring hole and scrapes its inner wall, thus cleaning the inner wall of the anchoring hole. At the same time, the external suction pipe is connected through the rotating connector 508, generating suction on the first dust collection cylinder 507, the fitting tube 502, and the first suction tube 503. The dust scraped off by the elastic scraper 302 inside the anchoring hole is sucked into the first dust collection cylinder 507 through the suction tube opening 506 and the cracked strip hole on the elliptical elastic expansion tube 505. This achieves simultaneous dust collection while disturbing and scraping the dust remaining on the inner wall of the anchoring hole.

[0052] By leveraging the elastic expansion of the elastic scraper 302, before it is inserted into the anchoring hole, the rotating ring 103 binds the three elastic scrapers 302, causing them to contract and press tightly against the first suction pipe 503, thus facilitating insertion into the anchoring hole. After insertion, the three elastic scrapers 302, no longer bound by the rotating ring 103, will recover through elastic deformation and press against the anchoring hole wall. The same set of elastic scrapers 302 can adapt to a certain range of anchoring hole diameters, thus eliminating the need for frequent tool changes, reducing tool costs, and improving the cleaning efficiency of batch anchoring.

[0053] Example 2, as Figure 7 , Figure 8 and Figure 10 As shown, the elastic scraper 302 rotates on the inner wall of the anchor hole to scrape away dust. The scraped dust falls to the bottom of the hole. The suction generated by the suction pipe 506 can draw most of the dust into the first suction pipe 503 and then into the first dust collection cylinder 507 for collection. When the three elastic scrapers 302 expand significantly, the bottom of the elastic scrapers 302 will gradually move above the suction pipe 506, so the suction pipe 506 will be against the bottom of the hole. As the first suction pipe 503 continues to extend into the hole, until the bottom of the three expanded elastic scrapers 302 is against the bottom of the hole, the elastic elliptical expansion tube 505 will be squeezed. At this time, the multiple cracked holes on the elliptical expansion tube 505 will expand accordingly. At this time, the suction port of the first suction pipe 503 will become a spherical suction port, so that the suction direction covers the bottom, top and sides, further increasing the suction range and improving the suction effect.

[0054] Example 3, as Figures 1 to 4 As shown, when the depth of the rebar hole is small, after pushing the threaded connecting cylinder 301 close to the rotating ring 103 through the fitting tube 502, the main body 1 will be lifted up, causing the rubber cover 202 to leave the ground. By rotating the clamping bolt knob 207, the clamping and positioning of one of the positioning support bars 203 can be released. At this time, two of the positioning support bars 203 can be pushed to slide inside the adjusting sliding hole 101 through the sliding connecting block 205, so that the bottom of the rubber cover 202 is close to the plane where the rebar hole is located. Then tighten the clamping bolt knob 207 to reposition it, which further improves the applicability of the device. In addition, through the anti-diffusion mechanism 2, the rubber cover 202 can be placed on the surface of the hole during the cleaning process to prevent dust from spreading outward. And by adjusting the piston cylinder 20 The sliding connection between the piston bottom 102 and the piston cylinder 201 forms a chamber between the adjusting piston cylinder 201 and the rubber cover 202. The chamber is connected to the second dust collection cylinder 406 via a connecting pipe through the second suction pipe connector 204. The top of the second dust collection cylinder 406 is connected to a second suction pipe, which can simultaneously clean the holes and vacuum the interior of the adjusting piston cylinder 201 and the rubber cover 202. This allows dust that has diffused into the rubber cover 202 to be sucked into the second dust collection cylinder 406. During this process, the connection between the center of the rotating ring 103 and the interior of the adjusting piston cylinder 201 allows external air to enter the adjusting piston cylinder 201 through the rotating ring 103, further preventing dust from the rubber cover 202 and the interior of the adjusting piston cylinder 201 from diffusing into the external environment through the rotating ring 103.
