Description

Technical Field

[0001] The utility model relates to a highway base drilling device, belonging to the technical field of highway drilling equipment. Background Art

[0002] Highway refers to public roads between cities, between urban and rural areas, and between villages that can be used for driving, which have been accepted and approved by the transportation authority. It includes highways that have been built and approved by the transportation authority. It should also include highways that are designed in accordance with national highway engineering technical standards, approved by relevant national administrative departments, and are under construction by the transportation authority. Drilling equipment is needed when drilling holes in the highway base.

[0003] According to the announcement number CN213450231U, a highway base drilling machine is disclosed. The highway base drilling machine achieves the effect of accurately controlling the depth of the drilling hole by setting a positioning nut, a threaded rod, a support spring and a transmission frame, and solves the problem that the depth of the drilling hole of the current drilling machine is not easy to control during the drilling process, thereby causing great changes in the installation of subsequent equipment. During the use of the above-mentioned device, when the device is moved to a suitable position, the user is required to rotate four handles respectively so that the support frame contacts the road surface. Each time the device is rotated, in order to avoid the movement of the device and the displacement of the position of the drill rod, the user is required to lift the device to rotate the handle. At this time, since the driving device that provides driving force to the drill rod is heavy, the device is inconvenient to adjust. After the drilling is completed, it is necessary to rotate multiple handles again to make the moving wheel contact the road surface. When the drilling depth of the device is adjusted by the positioning nuts, multiple positioning nuts need to be adjusted, so that the use of the device is more cumbersome and the labor intensity of the user is greater.
