The invention discloses a drilling device for
building construction. The drilling device comprises a
machine body, wherein a hydraulic telescopic rod is fixedly connected to the top of an inner cavityof the
machine body, a moving plate is fixedly connected to the output end of the hydraulic telescopic rod, a motor is fixedly connected to the bottom of the moving plate, a
drill bit is fixedly connected to the output shaft of the motor, and the bottom of the
drill bit penetrates through the
machine body and extends to the outside of the machine body. According to the drilling device, through the arrangement of the hydraulic telescopic rod, the moving plate, the motor, the
drill bit, a first damping spring, a fixing frame, a second damping spring, a limiting rod and a placing plate, drillingoperation can be automatically carried out, vibration generated by drilling can be effectively reduced in the drilling process, and construction personnel can use conveniently, time and labor are saved, and at the same time, the problems that a traditional drilling device always drills manually, the drilling efficiency is low, manpower and
material resources are wasted, vibration is generated inthe drilling operation at the same time, a
drill bit is damaged in long-time operation, and the personal safety of users is endangered in serious cases are solved.
