Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering, in particular to a mobile drilling device for civil engineering. Background Art

[0002] Civil engineering is a general term for the science and technology of building various types of engineering facilities. It refers to the materials and equipment used, and the technical activities such as survey, design, construction, maintenance, and repair carried out, as well as the objects of engineering construction, that is, various engineering facilities built above or below the ground, on land or in water, which directly or indirectly serve human life, production, military, and scientific research, such as houses, roads, railways, pipelines, tunnels, bridges, canals, dams, ports, power stations, airports, offshore platforms, water supply and drainage, and protective projects.

[0003] At present, an existing drilling device for civil engineering (such as patent number: CN217169170U) discloses a drilling device for civil engineering, including a support plate, the upper end of the support plate is fixedly connected to a support column, the inner cavity of the support column is slidably connected to a lifting rod, the upper end of the lifting rod is fixedly connected to the support rod, the upper end of the support rod is chiseled with a groove, the inner cavity of the support rod is penetrated by a first screw, the outer end of the first screw is sleeved with a clamping plate, and the clamping plate is located on the upper side of the support rod. This scheme can be realized in the process of drilling holes on the wall surface, by fixing the drilling tool on the drilling device, and adjusting the height of the drilling device according to the drilling position. After a single wall hole is drilled, the drilling device can be moved horizontally to maintain the level between multiple hole positions, meet the needs of drilling holes in civil engineering construction, and at the same time ensure that the drilled holes are perpendicular to the wall surface, thereby improving the qualified rate of the obtained wall holes.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems:

[0005] 1. The existing device is not equipped with a horizontal adjustment mechanism. Not all locations on the construction site are flat, and there will be some potholes. If the device is constructed at a location with potholes, the support plate will tilt, causing the support rod to tilt as well. After the clamping plate above the support rod clamps the punching device, it will be difficult to align with the points where holes need to be punched because of the tilt of the support plate. Therefore, the existing device has a small application scenario and is not easy to use in potholes.

[0006] 2. The existing device is not provided with a stopping device. When the worker is drilling, the universal wheel may be displaced due to the force generated by the worker's construction action, which may cause injury to the worker. Therefore, the existing device may cause injury to the worker when in use. Utility Model Content
