Description

Technical Field

[0001] This utility model relates to the field of road drilling technology, and in particular to a drilling device for road surface engineering. Background Technology

[0002] Drilling holes in road surfaces is a common construction operation, and its main purposes include the following:

[0003] Installation of traffic signs and signals: To install traffic signs, streetlights, traffic signals and other facilities, holes need to be drilled in the road surface to secure the brackets and foundations.

[0004] Pipeline laying: During road construction or renovation, it is necessary to lay pipelines for water supply, drainage, gas, electricity, and communications. Drilling is used to bury these pipelines below the road surface without affecting traffic above the surface.

[0005] Inspection and Repair: Drilling holes in the road surface allows for the inspection of the structural layers, such as the density and stability of the base and subgrade. Furthermore, drilling can also be used to repair or replace damaged road structural layers.

[0006] Drainage: In road construction, to prevent water from accumulating under the road surface, holes may be drilled at specific locations to install drainage pipes or wells to ensure that water under the road surface can be effectively drained.

[0007] Anchoring operations: In some projects, such as bridge construction and mountain support, it is necessary to drill holes in the road surface to install anchor bolts or other anchoring facilities.

[0008] Sampling and analysis: To assess the quality of road materials or to conduct scientific research, boreholes may be drilled to take samples, and the performance of the road surface can be understood by analyzing the samples.

[0009] Stress relief: When cracks or deformations occur on the road surface, drilling can release stress and prevent cracks from widening or deformation from worsening.

[0010] Convenient construction: During road construction, drilling can be used for the installation of temporary facilities, such as fixing piles for construction barriers.

[0011] Chinese patent CN 217872628 U discloses a road drilling machine, belonging to the field of drilling machine technology. It includes a base, a drilling motor mounted above the base, and a drilled pile coaxially connected to the output shaft of the drilling motor. The base has casters installed at all four corners of its bottom wall. Two vertical hydraulic telescopic rods are located above the base, with a lifting platform fixedly connected to their bottom ends. U-shaped protrusions are symmetrically welded to both sides of the base's top wall. Each protrusion contains a first electric telescopic rod and a baffle connected to each other. Protrusions are integrally welded to all four corners of the base, and corner piles are welded to the top walls of the four protrusions. Support motors are installed on the top walls of the four corner piles. This road drilling machine effectively shields the debris and soil ejected during drilling, reducing the impact on the surrounding environment and minimizing harm to construction workers.

[0012] The aforementioned device shields the debris and soil ejected into the outside world during drilling of bored piles, reducing the impact on the surrounding environment and the harm to construction workers. However, in the existing technology, after drilling the road surface, debris remains in the hole, which can affect the subsequent insertion of rod-shaped objects. Utility Model Content

An air outlet 9 is provided at the drive end of the lifting drive device 8. A connecting pipe 10 is provided at the output end of the blower assembly 7. The other end of the connecting pipe 10 is connected to the air outlet 9.

[0038] When in use, this device can move the housing 3 and then drill holes in the road surface using the drilling component. The dust cover 5 can prevent dust from escaping or block flying gravel, reducing the impact on the surrounding environment. After drilling, the blowing component 7 moves the housing 3 via the horizontal moving component, moving the air outlet 9 above the hole. Then, the lifting drive device 8 moves the air outlet 9 into the hole, thus blowing away the gravel inside. Compared with the prior art, this device, through the lifting drive device 8, can move the air outlet 9 into the hole to blow away the gravel inside, preventing it from affecting subsequent use. This solves the problem in the prior art where gravel remains in the hole, affecting the subsequent insertion of rod-shaped objects.

[0039] Furthermore, the air outlet 9 is cylindrical, and a plurality of air outlet holes 12 are provided on the outer periphery of the air outlet 9. The air outlet holes 12 are connected to the interior of the air outlet 9. By making the air outlet 9 cylindrical, it can be adapted to the hole, making it easy to insert the air outlet 9 into the hole, and then blow out the gravel in the hole through the provided air outlet holes 12, which is convenient for subsequent use.

The dust cover 5 is fixedly positioned at the bottom of the housing 3 and located on the outer periphery of the drill bit 20. The drilling motor 18 can drive the drilling pile 19 to rotate, which in turn drives the drill bit 20 to rotate, thus enabling drilling of the road surface.
