Description

Technical Field

[0001] The utility model relates to the field of civil engineering, and more specifically, to a construction lifting device for civil engineering. Background Technique

[0002] When carrying out civil engineering construction, sometimes it is necessary to perform drilling operations on the wall surface. The patent publication number CN217169170U discloses a drilling device for civil engineering, including a support plate. The upper end of the support plate is fixedly connected with a support column. The inner cavity of the support column is slidably connected with a lifting rod. The upper end of the lifting rod is fixedly connected with a support rod. A groove is opened at the upper end of the support rod. A first screw rod passes through the inner cavity of the support rod. A pressing plate is sleeved on the outer end of the first screw rod. The pressing plate is located above the support rod. This solution can realize that during the process of drilling holes on the wall surface, the drilling tool is fixed on this drilling device, and the height of the drilling device can be adjusted according to the drilling position. After a single wall hole is drilled, this drilling device can be horizontally moved to keep the horizontal between multiple hole positions, meet the needs of civil engineering construction drilling, and at the same time ensure that the drilled holes are perpendicular to the wall surface, improving the qualification rate of the obtained wall holes.

[0003] In the existing technology, however, the above-mentioned lifting device cannot perform horizontal lateral movement during use, resulting in the need to move the base every time when drilling different walls. And as the height is increased, the center of gravity of the overall equipment also moves up. Therefore, more attention needs to be paid during movement to prevent impact on the drilling device or the overall equipment from tipping over. If it needs to be lowered during movement, it will take more time to raise and lower back and forth. Finally, the manual operation of the lifting further increases the working intensity of the staff.
