Description

TECHNICAL FIELD

[0001] The utility model relates to a retractable movable ceiling drilling device. BACKGROUND

[0002] In the line installation engineering of underground garage, workshop and the like, a large number of bridge frames, lighting bus ducts, ventilation ducts and the like need to be erected, and the above-mentioned facilities are generally erected on the ceiling. In order to facilitate the fixing on the ceiling, it is generally necessary to drill mounting holes for expansion bolts on the ceiling, and the expansion bolts are used to realize the overhead fixing of the above-mentioned facilities. At present, there are mainly two ways to drill holes for expansion bolts on the ceiling. One is pure manual climbing operation, and the hole drilling personnel hold a drill and climb the scaffold to drill holes. This method has the risk of falling from a high altitude, and the labor intensity is large. The other way is to drill holes on the ground with the help of auxiliary work. For example, the Chinese utility model patent with the publication number CN215093420U discloses a drill support frame for drilling holes in the roof of a house. The support frame uses a parallelogram linkage mechanism to realize the support and fixation of the drill, and the rotation of the parallelogram linkage mechanism on the ground realizes the ceiling drilling operation of the drill. Although the support frame can make the worker not need to climb the operation, due to the movement characteristics of the parallelogram linkage mechanism, the drill also has a horizontal movement during the vertical upward movement, which causes the drill to have a certain horizontal movement during the hole drilling process, and then the drilled hole is actually a long circular hole. If the long circular hole is long, it will affect the fixing firmness of the expansion bolt in the hole, and then affect the overhead safety of the overhead facilities such as bridge frame, lighting bus duct and ventilation duct.
