Description

Technical Field

[0001] This utility model belongs to the field of anchor bolt support technology, specifically relating to a slope protection anchor bolt drilling device. Background Technology

[0002] Anchor bolt support is a reinforcement and support method used in surface engineering projects such as slopes and deep foundation pits, as well as in underground chamber construction such as tunnels and mining areas. It involves using bolts made of metal, wood, polymer, or other materials, driven into pre-drilled holes in the surface rock or the surrounding rock mass. The bolts utilize the special structure of their head and body, and the tail support plate (which may be omitted), or rely on bonding to combine the surrounding rock with the stable rock mass, creating a suspension effect, a composite beam effect, or a reinforcement effect to achieve the purpose of support. Pole support is a reinforcement and support method used in surface engineering such as slopes and deep foundation pits, as well as underground chamber construction such as tunnels and mining areas. Pole columns made of metal, wood, polymer or other materials are driven into pre-drilled holes in the surface rock or the rock mass surrounding the chamber. The special structure of the head and body of the pole and the tail support plate (which may be omitted) or the bonding effect are used to combine the surrounding rock with the stable rock mass to produce a suspension effect, composite beam effect or reinforcement effect, so as to achieve the purpose of support.

[0003] Existing anchor bolt support requires drilling into the slope during installation. This drilling process discharges large amounts of sand and gravel from the holes, causing significant dust pollution during windy weather, impacting the drilling environment and causing interference. This issue has become a pressing problem for researchers in this field. Utility Model Content

[0004] The purpose of this utility model is to provide a slope protection anchor drilling device to address the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a slope protection anchor drilling device, including a driving device, a connecting rod installed at the rotating end of the driving device, and a drill bit installed at the end of the connecting rod, and a handle is provided on the driving device.

[0006] It should be noted that the drive device can be an electric motor or an oil extraction machine.

[0007] It also includes a housing, which has a through hole for the connecting rod and the drill bit to pass through. The housing has an inner cavity inside, and the bottom of the housing has a discharge port communicating with the inner cavity. A discharge pipe is installed on the discharge port.

[0008] By adopting the above technical solution: during drilling, the shell is installed on the slope protection, with its through hole aligned with the borehole. The sand and gravel discharged from the borehole enter the inner cavity and are finally discharged through the outlet and discharge pipe, forming a closed channel that can guide the sand and gravel. This enables the sand and gravel generated by drilling to be discharged quickly and orderly, preventing the sand and gravel from scattering everywhere. The sand and gravel can be discharged to a designated location, and the physical barrier formed by the shell effectively blocks the dust generated when the sand and gravel fall.

[0009] Preferably, the housing is provided with an inlet communicating with the inner cavity, and an inlet pipe is connected to the inlet.

[0010] By adopting the above technical solution, water is injected into the inner cavity of the shell through the inlet pipe, which further reduces the generation of dust and makes the discharge of sand and gravel smoother.

[0011] Preferably, a valve is provided on the inlet.

[0012] Preferably, several connecting blocks are fixedly installed on the outer wall of the housing, and each connecting block has an installation hole, in which a fixing nail is installed.

[0013] By adopting the above technical solution, it is easier to fix the shell on the slope using fixing nails.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are: This utility model,

[0015] (1) By setting up the shell, inner cavity, outlet and discharge pipe, a closed channel is formed that can guide the sand and gravel, so as to realize the rapid and orderly discharge of the sand and gravel generated by drilling, avoid the sand and gravel from scattering everywhere, and discharge the sand and gravel to a designated location. In addition, the physical barrier formed by the shell effectively blocks the dust generated when the sand and gravel fall, reduces air pollution, creates a healthier working environment for construction personnel, and reduces the impact on the surrounding ecological environment.
