Description

Technical Field

[0001] This utility model belongs to the technical field of highway maintenance equipment, and in particular, it is a drilling device for highway maintenance. Background Technology

[0002] Highway maintenance is the upkeep and maintenance of highways. Upkeep focuses on the entire process from the time a road is built and opened to traffic, while maintenance focuses on repairing damaged parts. Highway maintenance generally requires drilling into the road surface using drilling equipment to facilitate the assessment of road surface quality. However, most drilling equipment currently lacks limiting components, meaning that the entire device is limited only by the wheels contacting the ground. This results in insufficient stability of the device during drilling, making it prone to deviation and reducing the effectiveness of drilling into the highway.

[0003] A Chinese patent (authorization announcement number CN215520756U) discloses a drilling device for highway maintenance, which includes: "a first support frame, a second support frame fixedly connected to one side of the first support frame, a first motor fixedly connected to one side of the first support frame, a lead screw fixedly connected to one side of the first motor, a slide rail opened inside the second support frame, and a first moving rod threadedly connected to the outer surface of the lead screw."

[0004] It is evident that the cited patent document suffers from the problem of easy deviation during drilling. Utility Model Content

[0005] The purpose of this utility model is to provide a drilling device for highway maintenance to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drilling device for highway maintenance, comprising a drilling base, two upright plates symmetrically welded to the top surface of the drilling base, rotating rods rotatably connected to opposite sides of the two upright plates, two first bevel gears fixedly sleeved on the periphery of each rotating rod, two threaded shafts rotatably connected to the top surface of the drilling base via pins, second bevel gears meshing with the two first bevel gears respectively connected to the top ends of the two threaded shafts, lifting frames threadedly sleeved on the periphery of each of the two threaded shafts, supporting base plates connected to the bottom surfaces of the two lifting frames through the drilling base, fixing plates installed on one side of each of the two upright plates, through holes opened on the top surfaces of each of the two fixing plates, bearings connected to the inner walls of each of the two through holes, and the periphery of the top ends of the two threaded shafts passing through the two bearings and fixedly connected to the inner walls of the two bearings.

[0007] Preferably, a top plate is mounted on the top surface of the drilling base via a bracket, and a hydraulic cylinder is mounted on the top surface of the top plate.

[0008] Preferably, the piston rod of the hydraulic cylinder passes through the top plate and is connected to a horizontal plate, and a drive motor is installed on the bottom surface of the horizontal plate.

[0009] Preferably, the output end of the drive motor is connected to a drill bit for drilling holes in the road, and a protective shell is fitted around the lower half of the drill bit.

[0010] Preferably, two connecting rods are symmetrically installed on the periphery of the protective shell, and the top ends of both connecting rods extend through to the top of the horizontal plate.

[0011] Preferably, the top ends of both connecting rods are connected to limit blocks, and a water tank with a water pump is installed on the top surface of the top plate.

[0012] Preferably, the water pump on one side of the water tank is connected to a telescopic hose, and the free end of the telescopic hose passes through the top plate and the protective shell and is connected to a nozzle.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This drilling device for highway maintenance provides power to rotate two first bevel gears by rotating a rotating rod, thereby rotating two threaded shafts and driving the support base plate to move longitudinally. This allows it to closely adhere to the highway and lift the drilling base. Compared to existing devices for drilling highways, this device increases the contact area between the device and the highway, thus improving the stability of the device during drilling.

[0015] By covering the drill bit with a protective shell, the dust generated during drilling can be protected, reducing the amount of dust that can fly around and pollute the environment.

[0016] Water can be pumped through a hose and delivered into the protective housing to spray the drill bit, thereby reducing the temperature generated by the drill bit during drilling and extending its service life. Attached Figure Description

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0026] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0027] like Figures 1 to 4 The device shown is a drilling and drilling device for highway maintenance, including a drilling base 1. The bottom surface of the drilling base 1 is equipped with multiple casters, which makes it convenient for personnel to move the drilling base 1 to the position where drilling is required.

[0028] Two vertical plates 2 are symmetrically welded to the top surface of the drilling base 1. A rotating rod 3 is rotatably connected to one side of the two vertical plates 2. One end of the rotating rod 3 passes through the vertical plate 2 and is connected to a handle. Two first bevel gears 4 are fixedly sleeved on the periphery of the rotating rod 3. Two threaded shafts 5 are rotatably connected to the top surface of the drilling base 1 through a pin. The top ends of the two threaded shafts 5 are respectively connected to second bevel gears 6 that mesh with the two first bevel gears 4. By rotating the handle, the operator can drive the rotating rod 3 to rotate, thereby driving the two first bevel gears 4 to rotate. Since the two first bevel gears 4 mesh with the two second bevel gears 6 respectively, the rotation of the two first bevel gears 4 will drive the rotation of the two second bevel gears 6, thereby driving the two threaded shafts 5 to rotate.

[0029] Lifting frames 7 are threadedly fitted around the periphery of both threaded shafts 5. Both lifting frames 7 are inverted U-shaped. The bottom surfaces of the two lifting frames 7 pass through the drilling base 1 and are connected to the support base plate 8. When the two threaded shafts 5 rotate, they will drive the two lifting frames 7 to move downwards, which in turn will drive the two support base plates 8 to move downwards and fit tightly against the road, thereby increasing the contact area between the device and the road, which can improve the stability during subsequent drilling and improve the drilling effect on the road.

[0030] Two vertical rods are installed on the top surface of the drilling base 1 and on both sides of the two threaded shafts 5. Two lifting frames 7 are slidably sleeved on the periphery of the two vertical rods, so that the lifting frames 7 will move around the periphery of the vertical rods when they move, thus limiting the movement of the lifting frames 7.

[0031] A fixing plate 9 is installed on one side of each of the two upright plates 2. A through hole 10 is opened on the top surface of each of the two fixing plates 9. A bearing 11 is connected to the inner side wall of each of the two through holes 10. The outer side wall of each of the two bearings 11 is connected and fixed to the inner side wall of each of the two through holes 10. The periphery of the top end of each of the two threaded shafts 5 passes through the two bearings 11 and is connected and fixed to the inner side wall of each of the two bearings 11. When the threaded shaft 5 rotates, it will drive the inner ring of the bearing 11 to rotate, so that the bearing 11 can support the position of the threaded shaft 5 without affecting the rotation.

[0032] A top plate 12 is mounted on the top surface of the drilling base 1 via a bracket. A hydraulic cylinder 13 is mounted on the top surface of the top plate 12. The piston rod of the hydraulic cylinder 13 passes through the top plate 12 and is connected to a horizontal plate 14. A drive motor 15 is mounted on the bottom surface of the horizontal plate 14. The output end of the drive motor 15 is connected to a drill bit 16 for drilling the road. By activating the hydraulic cylinder 13, the horizontal plate 14 can be moved downward, thereby moving the drill bit 16 downward. Then, by activating the drive motor 15, the drill bit 16 can be rotated and, in conjunction with the hydraulic cylinder 13, moved downward, thereby drilling the road.

[0033] A protective shell 17 is fitted around the lower half of the drill bit 16. Two connecting rods 18 are symmetrically installed around the protective shell 17, with the tops of both connecting rods 18 extending above the horizontal plate 14. The top surface of the horizontal plate 14 has symmetrical through slots for the two connecting rods 18 to pass through. The tops of both connecting rods 18 are connected to limit blocks 19. Initially, the lower half of the drill bit 16 is inside the protective shell 17. When the hydraulic cylinder 13 moves the horizontal plate 14 downward, the connecting rods 18 and the protective shell 17 will move downward synchronously due to gravity, and the protective shell 17 will move downward first. With the drill bit 16 against the road, it continues to move downwards, allowing the connecting rod 18 to move inside the through groove, so that the drill bit 16 can also be against the road and drill. When the drill bit 16 is drilling, the protective shell 17 will cover the lower half of the drill bit 16, thus protecting the dust from being scattered and polluting the environment. After drilling is completed, the hydraulic cylinder 13 drives the horizontal plate 14 to move upwards. When the top surface of the horizontal plate 14 abuts against the limit block 19, it continues to move upwards, which drives the connecting rod 18 to move upwards, thereby driving the protective shell 17 to move upwards.

[0034] A water tank 20 with a water pump is installed on the top surface of the top plate 12. The water pump on one side of the water tank 20 is connected to a telescopic hose 21. The free end of the telescopic hose 21 passes through the top plate 12 and the protective shell 17 and is connected to a nozzle. When the drill bit 16 is drilling, the water pump is turned on, which can transport the water in the water tank 20 to the telescopic hose 21 and then to the nozzle to spray out. This can reduce the temperature generated by the drill bit 16 during drilling and improve the service life of the drill bit 16.

[0035] Working principle:

[0036] This drilling device for highway maintenance allows operators to move the drilling base 1 to the desired drilling position using a push handle. Turning the handle then rotates the lever 3, which drives two first bevel gears 4 to rotate. Since the two first bevel gears 4 mesh with two second bevel gears 6 respectively, their rotation drives the two second bevel gears 6, which in turn rotates the two threaded shafts 5. This causes the two threaded shafts 5 to move the two lifting frames 7 downwards, which in turn moves the two support base plates 8 downwards and close to the highway, increasing the contact area between the device and the highway and improving drilling stability. Then, activating the drive motor 15 and hydraulic cylinder 13 rotates and moves the drill bit 16 downwards, thus drilling the highway and improving the drilling efficiency.
