Technical Field
[0001] This utility model relates to the field of drilling equipment technology, and in particular to a rapid drilling device for road and bridge construction. Background Technology
[0002] A road and bridge drilling machine is a device used to drill holes in road surfaces or bridge decks. It mainly consists of a power system and drill bits. When working, the power system drives the drill bit to rotate, causing the drill bit to cut into the road surface or bridge deck to drill holes. It has a wide range of applications and plays an important role in many fields such as road and bridge construction.
[0003] The above-mentioned and existing technologies have the following drawbacks: During the drilling process in road and bridge construction, a large amount of dust will be generated at the drilling point between the drill bit and the road or bridge surface and spread into the air. In addition, gravel will be splashed over a large area on the road or bridge surface, which can easily pollute the surrounding air and the road or bridge surface, thereby reducing the practicality of the road and bridge drilling machine.
[0004] Therefore, a rapid drilling device for road and bridge construction is proposed. Utility Model Content
[0005] The purpose of this invention is to solve the problems that drilling at the point where the drill bit hits the road or bridge surface generates a large amount of dust that diffuses into the air, and also causes gravel to fly over a large area on the road or bridge surface, which easily pollutes the surrounding air and the road or bridge surface. Therefore, a rapid drilling device for road and bridge construction is proposed.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rapid drilling device for road and bridge construction, comprising a frame, a pull plate fixedly mounted on the upper surface of the frame, a plurality of casters rotatably connected to the lower surface of the frame, a bracket fixedly mounted on the upper surface of the frame, a hydraulic cylinder fixedly mounted inside the bracket, a mounting frame fixedly mounted on the output end of the hydraulic cylinder, a motor fixedly mounted on the inner wall of the mounting frame, a drill bit fixedly mounted on the output end of the motor, a sealing plate fixedly mounted on the surface of the bracket, the output end of the hydraulic cylinder penetrating the sealing plate, an electric push rod fixedly mounted on the lower surface of the sealing plate, a connecting ring fixedly mounted on the output end of the electric push rod, and a folding tube fixedly mounted between the connecting ring and the sealing plate.
[0007] The aforementioned components achieve the following effects: through the cooperation of components such as sealing plates, folding tubes, and connecting rings, the dust generated during rapid drilling of road or bridge surfaces can be shielded, preventing the dust from spreading into the surrounding air in large quantities, and limiting the range of flying stone fragments, which facilitates subsequent cleaning of dust and stone fragments, thus improving the practicality of the road and bridge drilling machine.

[0010] Preferably, an elastic ring is fixedly fitted onto the lower surface of the connecting ring.
[0011] The effect achieved by the above-mentioned components is that the elastic ring deforms when it is pressed against the road surface or bridge surface, thus filling the gap between the connecting ring and the road surface or bridge surface.
[0012] Preferably, a plurality of steel wires are fixedly assembled on the lower surface of the connecting ring.
[0013] The effect achieved by the above components is that the steel wire can buffer the stone fragments, reduce the impact of the stone fragments on the elastic ring, and thus extend the service life of the elastic ring.
[0014] Preferably, a fixing plate is fixedly mounted on the upper surface of the frame, a rectangular rod is fixedly mounted on the surface of the fixing plate, and a plurality of counterweights are slidably connected to the surface of the rectangular rod.
[0015] The effect achieved by the above components is that by setting counterweights and other components, the weight of the frame can be increased during drilling, thereby improving the stability of the drill bit during drilling and preventing the frame from failing to provide sufficient pressure for the drill bit to move downward normally.
[0016] Preferably, a retaining plate slides through the counterweight, and the surface of the rectangular rod has a groove that matches the retaining plate.
[0017] The effect achieved by the above components is that the slot restricts the position of the card plate, thereby restricting the position of the counterweight.

[0029] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0031] like Figures 1-5As shown, this utility model provides a rapid drilling device for road and bridge construction, including a frame 1. A pull plate 2 is fixedly mounted on the upper surface of the frame 1, and several casters 3 are rotatably connected to the lower surface of the frame 1. A bracket 4 is fixedly mounted on the upper surface of the frame 1, and a hydraulic cylinder 5 is fixedly mounted inside the bracket 4. A mounting frame 6 is fixedly mounted on the output end of the hydraulic cylinder 5. A motor 7 is fixedly mounted on the inner wall of the mounting frame 6, and a drill bit 8 is fixedly mounted on the output end of the motor 7. A sealing plate 9 is fixedly mounted on the surface of the bracket 4, and the output end of the hydraulic cylinder 5 passes through the sealing plate 9. An electric push rod 10 is fixedly mounted on the lower surface of the sealing plate 9, and a connecting ring 11 is fixedly mounted on the output end of the electric push rod 10. A folding tube 12 is fixedly mounted between the connecting ring 11 and the sealing plate 9. The device passes through the sealing plate 9 and the folding tube. The sealing plate 9 and connecting ring 11 work together to shield the dust generated during rapid drilling of road or bridge surfaces, preventing the dust from spreading into the surrounding air and limiting the range of flying debris, thus facilitating subsequent cleaning of dust and debris and improving the practicality of the road and bridge drilling machine. The lower surface of the sealing plate 9 is fixedly fitted with a limiting strip 13, and the upper surface of the connecting ring 11 is fixedly fitted with a limiting plate 14. The limiting plate 14 is slidably connected to the limiting strip 13. The lower surface of the sealing plate 9 is fixedly fitted with a limiting rod 15, which is slidably connected to the mounting frame 6. The limiting plate 14 follows the connecting ring 11 and slides along the surface of the limiting strip 13. The combination of the limiting strip 13 and the limiting plate 14 can limit the movement path of the connecting ring 11.
[0032] like Figure 2 and Figure 3 As shown, an elastic ring 16 is fixedly mounted on the lower surface of the connecting ring 11. When the elastic ring 16 comes into contact with the road surface or bridge surface, it will deform and fill the gap between the connecting ring 11 and the road surface or bridge surface. Several steel wires 17 are fixedly mounted on the lower surface of the connecting ring 11. The steel wires 17 can buffer the gravel and reduce the impact force of the gravel on the elastic ring 16, thereby extending the service life of the elastic ring 16.
[0033] like Figure 4 and Figure 5As shown, a fixing plate 18 is fixedly mounted on the upper surface of the frame 1, and a rectangular rod 19 is fixedly mounted on the surface of the fixing plate 18. Several counterweights 20 are slidably connected to the surface of the rectangular rod 19. By setting the counterweights 20 and other components, the weight of the frame 1 can be increased during drilling, thereby improving the stability of the drill bit 8 during drilling and preventing the frame 1 from failing to provide sufficient pressure for the drill bit 8 to move downward normally. A clamping plate 21 slides through the counterweight 20, and the rectangular rod 19... The surface of the plate 21 is provided with a slot 22 that is adapted to the plate 21. The slot 22 restricts the position of the plate 21, thereby restricting the position of the counterweight 20. The surface of the plate 21 is provided with a bevel. A circular frame 23 is fixedly mounted on one end of the plate 21. A spring 24 is sleeved on the surface of the plate 21. The two ends of the spring 24 are fixedly connected to the circular frame 23 and the counterweight 20, respectively. When the plate 21 is aligned with the slot 22, the spring 24 retracts, and the circular frame 23 will use the elastic force of the spring 24 to insert the plate 21 into the slot 22.
[0034] The overall working principle is as follows: During drilling operations in road and bridge construction, the frame 1 is pulled by the pull plate 2, and the casters 3 facilitate the movement of the frame 1. Once it is moved to the appropriate position, the output end of the electric actuator 10 is extended, and the connecting ring 11 moves downward with the output end of the electric actuator 10. At this time, the folding tube 12 extends, and the movement of the connecting ring 11 also drives the elastic ring 16 to move. When the elastic ring 16 comes into contact with the road surface or bridge surface, it deforms, filling the gap between the connecting ring 11 and the road surface or bridge surface. The limiting plate 14 slides along the surface of the limiting strip 13 along with the connecting ring 11. The limiting strip 13 and the limiting plate 14 cooperate to restrict the movement path of the connecting ring 11. Then, the motor 7 is turned on, and the motor 7 drives the drill bit 8 to rotate. Then, the output end of the hydraulic cylinder 5 is extended, and the output end of the hydraulic cylinder 5 passes through the sealing plate 9 to drive the mounting frame 6 to move along the arc surface of the limiting rod 15. The limiting rod 15 achieves the function of limiting the movement path of the mounting frame 6. The mounting frame 6 will drive the motor 7 to move, and the motor 7 will make the drill bit 8 press against the ground to drill a hole. During this process, the sealing plate 9, the folding tube 12 and the connecting ring 11 and other components work together to shield the dust generated during the drilling process, prevent the dust from spreading into the surrounding air in large quantities, and limit the range of stone fragments splashing, which facilitates the subsequent cleaning of dust and stone fragments. At the same time, the steel wire 17 can buffer the stone fragments, reduce the impact force of the stone fragments on the elastic ring 16, and thus extend the service life of the elastic ring 16.
[0035] During drilling, the counterweight 20 slides downwards along the surface of the rectangular rod 19. The counterweight 20 causes the clamping plate 21 to slide. When the rectangular rod 19 contacts the inclined surface of the clamping plate 21, the rectangular rod 19 presses against the clamping plate 21. The clamping plate 21 slides along the counterweight 20 and moves the circular frame 23. The movement of the circular frame 23 stretches the spring 24. When the clamping plate 21 aligns with the slot 22, the spring 24 contracts. The circular frame 23, with the help of the spring 24, inserts the clamping plate 21 into the slot 22. The slot 22 restricts the position of the clamping plate 21, thereby restricting the position of the counterweight 20. The counterweight 20 increases the weight of the frame 1, thus... This improves the stability of drill bit 8 during drilling and prevents the frame 1 from failing to provide sufficient pressure for drill bit 8 to move downwards normally. When it is necessary to adjust the weight of counterweight 20 according to the hardness of the road or bridge surface, pull the round frame 23 away from counterweight 20 to disengage the clamping plate 21 from the clamping slot 22, and then move counterweight 20 upwards to remove it. This reduces the weight of frame 1, ensuring normal drilling of softer road or bridge surfaces while also facilitating the pulling of frame 1. When the number of counterweights 20 increases, it is possible to drill harder road or bridge surfaces, thereby improving the practicality of using the road and bridge drilling machine.
[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
