The utility model discloses a punching device for house building construction. The punching device comprises a power assembly, a positioning assembly, a fixing assembly and a drill rod. The fixed end of the drill rod is detachably connected with the fixing assembly, the fixing assembly is used for clamping and fixing the fixed end of the drill rod, and the fixing assembly is further fixed to the power output end of the power assembly so as to drive the drill rod to rotate. The power assembly is detachably arranged on the positioning assembly, the positioning assembly is used for abutting against a to-be-punched face to be punched for positioning, and meanwhile the positioning assembly is further used for guiding and limiting the power assembly in the punching pushing direction so that the drill rod can vertically drill the to-be-punched face. According to the device, it can be ensured that the drill rod is always kept in the state of being perpendicular to the face to be punched in the punching process, the problem that punching is inaccurate due to the fact that the drill rod deviates or inclines in the drilling and beating process is solved, meanwhile, the drill rod is detachably connected with the fixing assembly so that the drill rod can be rapidly disassembled and replaced, then the downtime is shortened, and the production efficiency is improved. And the overall construction efficiency and the construction flexibility are improved.

This invention discloses a pole straightening device for power grid erection, applicable in the field of power equipment erection. The key technical features are: the lifting mechanism includes a lifting auxiliary component and bearings; a limit groove is provided on the left side of the lifting auxiliary component; a drive motor is installed at the top of the lifting auxiliary component; and the output end of the drive motor passes through the top of the lifting auxiliary component and is fixedly connected to a threaded rod via a coupling. The technical advantages are: by movably connecting the outer wall of the round rod to the U-shaped block, firstly, during the clamping process of the erection pole, it is convenient to place two semi-circular parts on the outer wall of the erection pole for clamping; secondly, as the U-shaped block rises under the action of the lifting block, the erection pole can also rotate around the round rod under the influence of gravity. With the cooperation of the lifting mechanism and the clamping mechanism, not only is straightening achieved, but the clamping effect is also more stable, less prone to swaying and shaking, greatly reducing the risk of slippage, minimizing construction accidents, and ensuring high safety.
