Description

Technical Field

[0001] This utility model relates to the field of drilling device technology, specifically to a drilling device for highway construction. Background Technology

[0002] In today's rapidly developing transportation system, hundreds or even thousands of vehicles travel on highways every day. Highways greatly facilitate people's travel, but long-term use will cause functional damage, so it is necessary to repave the highway. However, before that, it is necessary to drill holes in the highway to help workers carry out the repairs. At this time, a drilling device for highway construction is needed to carry out the drilling operation.

[0003] Chinese Patent CN213016175U discloses a horizontally and vertically adjustable drilling device for highway bridge construction. The device includes a base, a housing on the upper surface of the base, guide rods symmetrically arranged on both sides of the front end of the base, support rods sleeved on the guide rods, and an electric push rod between the support rods and the upper surface of the base. The electric push rod, support rods, and base are all bolted together. A mounting plate is installed in the middle of the support rod, and a drive motor is mounted on the upper surface of the mounting plate. The output end of the drive motor passes through the mounting plate and has a drill bit attached. This invention solves the problem that existing drilling devices are inconvenient to operate, making it difficult to drill vertically or horizontally into highways and bridges. By improving and optimizing the structure of the drilling device, it makes the device easy to move, thus facilitating flexible use. This drilling device also allows for stable vertical or horizontal drilling. However, some shortcomings remain and can be improved.

[0004] 1. This utility model controls the movement of the entire device by setting universal wheels and rollers at the low end of the base. However, it is worth noting that the road surface to be drilled is often uneven. If only universal wheels and rollers are used, the entire device is very likely to tip over. At the same time, the device will generate a lot of vibration when drilling, and this vibration will be transmitted to the user through the push handle.

[0005] 2. When the equipment is drilling, the friction between the drill bit and the ground will cause dust to fly around the hole. This flying dust will not only affect the user's vision while working, but may also adhere to the user's skin or even enter the user's mouth and nose, which will have a certain impact on the user's health and safety.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings.

[0032] The working principle of this utility model is as follows: Figures 1-5As shown, a drilling device for highway construction includes a base 1. A through hole 6 is first opened in the center of the top of the base 1. A connecting plate 14 is then arranged in the center above the through hole 6. A receiving plate 16 is arranged in the center below the connecting plate 14. Hydraulic telescopic cylinders 15 are fixedly connected to both sides of the top of the receiving plate 16, and the top of the hydraulic telescopic cylinders 15 is fixedly connected to the connecting plate 14. Simultaneously, a second motor 17 is arranged in the center of the top of the receiving plate 16. The second motor 17 is fixedly connected to the receiving plate 16 via a second motor base 18. The output shaft of the second motor 17 passes through... A receiving plate 16 is fixedly connected to a spiral drill bit 19. It should be noted that the bottom end of the spiral drill bit 19 is located below the base 1. The effect achieved is that when drilling is required, the motor 17 first drives the spiral drill bit 19 to rotate, and then the hydraulic telescopic cylinders 15 on both sides slowly push the receiving plate 16 downwards to perform the drilling operation. Connecting posts 13 are provided on both sides of the two hydraulic telescopic cylinders 15. The top ends of the connecting posts 13 are fixedly connected to the connecting plate 14, and the bottom ends of the connecting posts 13 are fixedly connected to threaded blocks 12. The bottom end of the threaded block 12 is slidably connected to the base 1. Simultaneously, threaded rods 7 are threadedly connected to both sides of the threaded block 12. Rotating frames 8 and 9 are rotatably connected to the front and rear ends of the threaded rods 7, respectively. The bottom ends of both rotating frames 8 and 9 are fixedly connected to the base 1. To allow the threaded rods 7 to rotate, motors 10 are installed behind each rotating frame 9. Each motor 10 is fixedly connected to the base 1 via a motor mount 11, and the output shafts of both motors 10 pass through the corresponding rotating frame 9 and are fixedly connected to the threaded rods 7. The effect achieved is that when the motors 10 on both sides drive the corresponding threaded rods 7 to rotate together, the threaded blocks 12 threaded to the threaded rods 7 will slide back and forth on the base 1. Then, a dust suppression device 5 is set at the front of the top of the base 1, and a handle 20 is fixedly connected to the rear of the top of the base 1. Next, support columns 2 are fixedly connected to the front and rear of both sides of the bottom of the base 1. Universal wheels 3 are set below the support columns 2. It is worth noting that all four universal wheels 3 have a self-locking function. Finally, the universal wheels 3 and the support columns 2 are connected to each other by a shock-absorbing device 4.

[0033] The above-mentioned structures together constitute the general appearance of the drilling device for highway construction according to this utility model.

[0034] To further explain the specific working principle of the drilling device for highway construction of this utility model, the dust suppression device 5 includes a rack 505 slidably connected to the middle of the front side of the top end of the base 1. An electric push rod 506 is fixedly connected to one side of the rack 505. In order to make the electric push rod 506 run more stably, a connecting frame 507 is provided on the side of the electric push rod 506 away from the rack 505. At the same time, the bottom end of the connecting frame 507 is fixedly connected to the base 1. Then, a gear 502 is meshed behind the rack 505. The bottom end of the gear 502 is fixedly connected to a rotating shaft 501. The bottom end of the rotating shaft 501 is rotatably connected to the middle of the front side of the top end of the base 1. The rotating shaft 501 is located in front of the through hole 6. The effect achieved is that when the electric push rod 506 pushes the rack 505... When 05 slides on the base 1, the gear 502 meshing with the rack 505 will drive the rotating shaft 501 to rotate together. Then, a connecting block 503 is fixedly connected to the top of the gear 502, and a fixing frame 509 is fixedly connected to the top of the connecting block 503. A water pipe 508 is provided on the fixing frame 509. One end of the water pipe 508 is fixedly connected to a nozzle 504 with a bracket. The bracket part of the nozzle 504 is fixedly connected to the rear end of the connecting block 503. It should be noted that the nozzle 504 is oriented diagonally downwards, and the end of the water pipe 508 away from the nozzle 504 is connected to the outside, and water is supplied to the nozzle 504 from the outside through the water pipe 508. Finally, it should be noted that the water pipe 508 is made of soft material and can rotate together with the connecting block 503.

[0035] The technical effect achieved by the technical solution composed of the above-mentioned technical features is as follows: When the electric actuator 506 is driven, its working rod will push the rack 505 to move away from the connecting frame 507. When the rack 505 slides on the base 1, the gear 502 meshing with it will simultaneously drive the rotating shaft 501 and the connecting block 503 to rotate together. While the connecting block 503 is rotating, it will drive the nozzle 504 and the connecting frame 507 to rotate together. Thus, the electric actuator 506 indirectly drives the nozzle 504 to rotate. At the same time, during this process, water will be continuously supplied to the nozzle 504 through the water pipe 508, and then the nozzle 504 will spray water to the outside.

[0036] To further explain the specific working principle of the drilling device for highway construction of this utility model, the rising shock absorption device 4 includes a second fixed shell 402 fixedly connected to the top of the universal wheel 3, and a first fixed shell 401 fixedly connected to the bottom of the support column 2. Here, the second fixed shell 402 is slidably connected inside the first fixed shell 401. Next, sliding blocks 405 are slidably connected to both sides of the bottom wall of the second fixed shell 402. Then, dampers 407 are fixedly connected to the front and rear parts of the sliding blocks 405 on the opposite sides. The opposite sides of the dampers 407 on both sides are fixedly connected to the second fixed shell 402. Meanwhile, springs 406 are wound around the front and rear dampers 407 on both sides. It should be noted that the two ends of the springs 406 are fixedly connected to the sliding block 405 and the fixed shell 402 respectively. The effect achieved is that when the sliding blocks 405 on both sides move towards the opposite side, they will compress the corresponding springs 406 and dampers 407. Then, rotating blocks 404 are rotatably connected to the top of the sliding blocks 405 on both sides, and fixed blocks 403 are rotatably connected to the top of the rotating blocks 404 on both sides. The top of the fixed blocks 403 is fixedly connected to the middle of the top wall of the fixed shell 401.

[0037] The technical effect achieved by the technical solution composed of the above-mentioned technical features is as follows: When the equipment starts drilling, the vibration generated by the auger drill bit 19 will be transmitted to the base 1. At the same time, this vibration will also generate a corresponding force, pressing the base 1 downward. Simultaneously, when the base 1 moves downward, the support column 2 fixedly connected to the bottom end of the base 1 will push the fixed shell 401 downward. The caster wheel 3 is placed on the ground at this time, so the relative position of the fixed shell 402 remains unchanged. That is, while the fixed shell 401 moves downward, it will push the two rotating blocks 404 to rotate in the direction of separation. When the rotating blocks 404 rotate, they will push the corresponding sliding blocks 405 to slide on the bottom wall of the fixed shell 402. When the sliding blocks 405 on both sides move in the direction of separation, they will compress the corresponding dampers 407 and springs 406. The force required to compress the springs 406 and the shock absorption function of the dampers 407 will jointly counteract the force generated by the vibration, thereby achieving the effect of stabilizing the equipment.

[0038] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.

[0039] In addition, all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer for control. The hydraulic telescopic cylinder mentioned in the article is connected to an external oil circuit. The detailed description of known functions and known components is omitted in the specific implementation of this disclosure. In order to ensure the compatibility of the equipment, the operating methods adopted are consistent with the parameters of commercially available instruments.
