Description

TECHNICAL FIELD

[0001] The present application relates to the field of urban traffic noise abatement construction, in particular to a sound barrier crash wall positioning and hole opening device. BACKGROUND

[0002] In the construction of urban roads, highways and other infrastructure, in order to effectively reduce the impact of traffic noise on the surrounding environment and ensure road traffic safety, sound barriers, traffic safety facilities and other facilities are often installed on both sides of the road. The installation of these facilities often requires drilling holes in the existing crash walls and anchoring them to provide a stable support point for the installation of subsequent facilities.

[0003] However, current drilling operations on crash walls mainly rely on traditional manual operation methods. Construction personnel need to position each drilling location, then hold a drill and use a simple support to carry out the operation. This operation mode has many drawbacks: on the one hand, due to the lack of effective integration and mobility design of drilling equipment, after completing an operation at a drilling location, the equipment needs to be manually moved to the next drilling point multiple times, which not only consumes a lot of time and labor, but also results in low operation efficiency, seriously affecting the progress of the entire project; on the other hand, the manual positioning method cannot guarantee accuracy and is prone to positioning deviations, which may affect the installation quality of subsequent sound barriers and traffic safety facilities, and even cause safety hazards due to insecure installation.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-8 This embodiment of a sound barrier anti-collision wall positioning opening device includes a connecting frame 1. The two end side walls of the connecting frame 1 are slidably connected to a clamping frame 1 2 and a clamping frame 2 3 respectively. The two end side walls of the clamping frame 1 2 and the clamping frame 2 3 are rotatably connected to a rolling wheel 2 5. The middle area of ​​the left and right ends of the bottom of the connecting frame 1 is rotatably connected to a rolling wheel 4. The rolling wheel 4 and the rolling wheel 2 5 on the connecting frame 1, the clamping frame 1 2, and the clamping frame 2 3 respectively slide in contact with the left and right end side walls and the top of the anti-collision wall, so that the opening equipment slides on the top of the anti-collision wall.

[0022] like Figures 1-5 As shown, a fixed box 6 is fixedly connected to the connecting frame 1, and a rotating handle 7 is rotatably connected to the fixed box 6. The rotating handle 7 can be driven to rotate, which in turn drives the bidirectional threaded rod 8 to rotate. The rotating handle 7 is fixedly connected to the bidirectional threaded rod 8 and drives the bidirectional threaded rod 8 to rotate inside the fixed box 6. Threaded sliders 9 are threaded to both ends of the bidirectional threaded rod 8. The bottoms of the two sets of threaded sliders 9 are fixedly connected to clamping frame 1 2 and clamping frame 2 3, respectively. The bidirectional threaded rod 8 drives the clamping frame 1 2 and clamping frame 2 3 to adjust the gap between them through the threaded sliders 9, and also adjusts the contact force between the rolling wheel 2 5 and the side wall of the anti-collision wall. Specifically, a vertical slider 10 is slidably connected to the outer wall of the clamping frame 3. Two sets of vertical sliders 10 are connected as one unit by a parallel slide rail 11. A parallel slider 12 is slidably connected to the outer wall of the parallel slide rail 11. A slide rod 13 is vertically connected to the parallel slider 12. A drill mounting plate 14 is slidably connected to the outer wall of the slide rod 13. The drill mounting plate 14 adjusts its position on the X-axis by moving on the parallel slide rail 11 via the parallel slider 12. The drill mounting plate 14 adjusts its Z-axis position by sliding on the slide rod 13. The drill mounting plate 14 adjusts its Y-axis position via the vertical slider 10. Specifically, a threaded rotating rod 15 is threadedly connected to the clamping frame 2 3. The other end of the threaded rotating rod 15 passes through the side wall of the clamping frame 2 3 and is rotatably connected to the fixing plate 16. The fixing plate 16 can press against the side wall of the anti-collision wall and achieve restriction on the drilling device. Specifically, in use, the connecting frame 1, clamping frame 1, and clamping frame 2 are placed on top of the crash barrier. The clamping frames 1 and 2 move downwards, causing the rollers 2 and 5 to be positioned at the left and right ends of the crash barrier. Then, torque is applied to rotate the handle 7, which in turn drives the bidirectional threaded rod 8 to rotate. The bidirectional threaded rod 8 drives the two sets of threaded sliders 9 to move, and the two sets of threaded sliders 9 move the clamping frames 1 and 2 closer together. The rollers 2 and 5 on the clamping frames 1 and 2 slide into contact with the front and rear side walls of the crash barrier. Then, the roller 4 at the bottom of the connecting frame 1 contacts the top of the crash barrier. The user can then apply a pushing force to the connecting frame 1, causing it to slide and adjust its position on the crash barrier via the rollers 1 and 2.

[0023] like Figures 1-5As shown, the side wall of the clamping frame 2 3 is provided with multiple sets of threaded holes 17 at equal intervals from top to bottom, which facilitates the height adjustment of the vertical slider 10. The vertical slider 10 is internally threaded with a threaded pin 18, which is used to connect with the threaded hole 17. A pressing spring 20 is fixedly connected inside the parallel slider 12. The pressing spring 20 provides the reset power for the pressing block 19. The pressing contact surface of the pressing block 19 is provided with a rubber layer. The other end of the pressing spring 20 is fixedly connected to the pressing block 19. The pressing block 19 is slidably connected to the inner side wall of the parallel slider 12. A locking rod 21 is fixedly connected to the side wall of the pressing block 19. The locking rod 21 engages with the locking groove inside the parallel slide rail 11. Specifically, a cleaning mechanism 22 is detachably connected to the electric drill mounting plate 14; Specifically, by sliding two vertical sliders 10 on the clamping frame 2 3, the height of the electric drill mounting plate 14 to the drilling position can be flexibly adjusted. After adjustment, it is fixed by threaded holes 17 and threaded pins 18 to meet the drilling requirements of different heights. In addition, it can slide on the graduated parallel slide rail 12 with the help of the parallel slider 12. By pressing the two pressing blocks 19, the locking rod 21 is disengaged from the inner wall of the limiting groove of the parallel slide rail 11, realizing the movement of the parallel slider 12, thereby driving the electric drill mounting plate 14 to the drilling position. After releasing the pressing blocks 19, under the elastic action of the pressing spring 20, the locking rod 21 is locked into the inner wall of the limiting groove to fix the parallel slider 12, ensuring that one end of the electric drill mounting plate 14 is directly facing the drilling position, realizing the precise adjustment of the drilling position and effectively improving the drilling efficiency.

[0024] like Figures 6-8 As shown, the cleaning mechanism 22 includes a connecting frame 221, which is detachably connected to the electric drill mounting plate 14 by bolts, making it convenient for the cleaning mechanism 22 to be installed on the electric drill mounting plate 14. A linear driver 222 is provided inside the connecting frame 221. The moving end of the linear driver 222 is fixedly connected to the connecting frame 223. The linear driver 222 is used to adjust the position of the connecting frame 223. Specifically, a first drive motor 224 is bolted to the connecting frame 223. The output shaft of the first drive motor 224 drives the first drive gear 225 to rotate and connect with the bottom of the connecting frame 223. The first drive gear 225 meshes with the gear on the side wall of the rotating cylinder 226 and drives the rotating cylinder 226 to rotate and connect with the connecting frame 223. The upper end of the rotating cylinder 226 is provided with a cylinder in the shape of an I-beam, and the gear is located in the middle area of ​​the I-beam to facilitate the meshing of the first drive gear 225 with the gear. A bidirectional screw 227 is rotatably connected inside the rotating cylinder 226. The two ends of the bidirectional screw 227 are threaded with sliding blocks 228. The side walls of the two sets of sliding blocks 228 are rotatably connected with connecting rods 229. The ends of the two sets of connecting rods 229 are rotatably connected to each other. Specifically, the ends of the two sets of connecting rods 229 are rotatably connected to the base of the cutting blade 2211, and the cutting blade 2211 is slidably connected to the groove 2210 on the rotating cylinder 226. The middle area of ​​the bidirectional screw 227 is fixedly connected to the worm in the worm gear 2212. The worm gear on the worm gear 2212 is fixedly connected to the lead screw 2213. The lead screw 2213 is internally threaded to the threaded cylinder 2214. The other end of the threaded cylinder 2214 is provided with a long strip-shaped cleaning brush, which slides outward through the groove 2210 at the other end of the rotating cylinder 226. Specifically, a connecting gear 2215 is rotatably connected to the top of the I-shaped cylindrical rotating cylinder 226. The connecting gear 2215 is fixedly connected to the bidirectional screw 227 and meshes with the driving gear 2217. The driving gear 2217 is fixedly connected to the output shaft of the second drive motor 2218. The second drive motor 2218 is fixedly connected to the top of the rotating cylinder 226 via a base. The connecting gear 2215, the bidirectional screw 227, and the suction cylinder 2216 are coaxially arranged, and the suction cylinder 2216 passes through the inner center of the bidirectional screw 227 and extends to the outer bottom of the rotating cylinder 226, facilitating negative pressure suction. Specifically, the cutting disc 2211 consists of a base and multiple sets of grinding blades connected together. The multiple sets of grinding blades are equidistantly arranged on the base. Through the equidistant arrangement of the multiple sets of grinding blades, the rotating cylinder 226 moves into the hole drilled in the anti-collision wall. The cutting disc 2211 moves outward and contacts the inner wall of the hole. The rotating cylinder 226 rotates and uses the grinding blades to perform rotational cutting on the inner wall of the hole, forming multiple sets of annular grooves on the inner wall of the hole. Specifically, the top of the parallel slide rail 11 is engraved with measuring scales to read the distance the electric drill moves, thereby controlling the horizontal drilling spacing; Specifically, a limiting groove is provided on one side of the parallel slide rail 11, and the inner walls of the limiting groove on both sides are toothed, and two locking rods 21 are slidably inserted into the limiting groove.

[0025] Specifically, after drilling is completed, the position of the connecting frame 1 is adjusted so that the cleaning mechanism 22 is located at the front end of the drilled hole. Then, the linear actuator 222 is controlled to drive the connecting frame 223 to move forward, so that the connecting frame 223 drives the rotating cylinder 226 to insert into the drilled hole. Then, the second drive motor 2218 is controlled to drive the drive gear 2217 to rotate. The drive gear 2217 drives the connecting gear 2215 to drive the bidirectional screw 227 to rotate. The bidirectional screw 227 simultaneously drives the worm on the worm gear 2212 to rotate. The worm gear on the worm gear 2212 drives the lead screw 2213 to rotate. The lead screw 2213 drives the threaded cylinder 2214 to move inward. The threaded cylinder 2214 also drives the cleaning brush to move into the rotating cylinder 226. The bidirectional screw 227 drives two sets of sliding blocks 228 to move. The sliding blocks 228 drive two sets of connecting rods 229 to push the cutting blade 2211 outward. The cutting blade 2211 is exposed at the outer end of the rotating cylinder 226. The rotating cylinder 226 drives the cutting blade 2211 to rotate and cut the side wall of the hole to form a V-shaped annular groove. After the drilling hole is cut, the bidirectional screw 227 is controlled to rotate in the opposite direction. The bidirectional screw 227 drives the cutting blade 2211 to move inward, the threaded cylinder 2214 to move outward, and the threaded cylinder 2214 drives the cleaning brush to move outward. At the same time, the suction cylinder 2216 is rotatably connected to the external suction device, and the suction cylinder 2216 sucks the inside of the drilling hole. Meanwhile, the rotating cylinder 226 rotates and drives the cleaning brush to sweep the inside of the drilling hole. The small particles of gravel powder generated are extracted outward through the suction cylinder 2216.
