[0002] In building construction, it is often necessary to drill holes in the position of the roof slab of the building structure. After retrieval, the prior art (application number: 202320842968.3) records "a building roof drilling device, including: a chassis; a fixed frame connected to the chassis, a positioning support is connected to the bottom of the fixed frame, and the shape of the positioning support is an arc with an opening facing upward; a fixed cylinder rotatably connected to the top of the fixed frame, the rotation axis of the fixed cylinder extends in the horizontal direction, and a locking component is arranged between the bottom side of the fixed cylinder and the positioning support, and the locking component can limit the rotation of the fixed cylinder. A top rod is slidably connected in the fixed cylinder in the up and down direction, and the top rod extends upward out of the fixed cylinder; a drill gun is connected to the top end of the top rod. The utility model can adjust the feeding angle of the drill gun according to different roof slab structures to ensure the perpendicularity of the drilling, improve the flexibility and versatility of the roof slab drilling process, and better meet different processing requirements."

[0003] However, although the building roof drilling device in the prior art realizes the flexibility and versatility of the roof slab drilling process, there are still some deficiencies: the process of manually adjusting the height and angle of the existing building construction structure top drilling device is relatively troublesome, which affects the drilling efficiency. Secondly, the support rod and the fixed frame are connected at a single point, and the vibration generated by the drill gun during use leads to poor stability, and then it is easy to cause the angle of the drill bit to change inside the roof slab, and then cause breakage. In addition, when drilling upward with a hand-held drill gun, it is necessary to continuously apply a force in the drilling direction, resulting in increased fatigue of the arm during long-term operation. Content of the Utility Model

[0004] In order to overcome the defects existing in the prior art, a drilling device for the top of a building construction structure is provided to solve the problems of poor overall stability, relatively troublesome process of adjusting the height and angle, and increased arm fatigue during the drilling process of the existing building construction structure top drilling device.

A cross plate is provided inside the bottom frame, and a first electric push rod is installed at the upper end of the cross plate. The upper end of the first electric push rod is connected to a sliding rod. The mounting frame is connected to the upper end of the sliding rod. A rotating shaft is rotatably connected inside the mounting frame, and locking sleeves are connected to both ends of the rotating shaft. A fixing block is connected to the middle of the rotating shaft, and a positioning cylinder is fixed to the upper end of the fixing block. A top rod is slidably inserted into the upper end of the positioning cylinder. The drill gun is connected to the upper end of the top rod. A connecting frame is welded to the lower end of the fixing block. Handles are provided at both lower ends of the connecting frame, and a second electric push rod is installed inside the connecting frame.

[0006] Further, the bottom frame includes inclined support legs at the lower end. The upper end of the support legs is connected to a top plate, and the sliding rod is vertically and slidably connected inside the top plate.

[0007] Further, the mounting frame is of a U-shaped frame structure, and the locking sleeves are provided outside the mounting frame. The locking sleeves and both ends of the rotating shaft are connected by threads.

[0008] Further, the connecting frame includes a horizontal plate at the upper side, and inclined rods are connected to the lower end of the horizontal plate. The lower end of the inclined rod is connected to a cross bar, and the handles are provided at both ends of the cross bar.

[0009] Further, the telescopic rod body of the second electric push rod slides upward through the fixing block and inserts into the positioning cylinder, and the telescopic rod is connected to the lower end of the top rod.

[0010] Further, a protective sleeve is provided outside the handle, and control buttons are provided near the handle. The control buttons are electrically connected to the first electric push rod and the second electric push rod.

[0011] Further, the positions of the telescopic rod body of the second electric push rod and the rotating shaft inside the fixing block are different, and the movement of the telescopic rod body and the rotating shaft do not interfere with each other.

[0012] The beneficial effects of the present utility model are as follows:

[0013] 1. When in use, move the bottom frame to the lower side of the top plate of the building structure where drilling is required. Then, control the first electric push rod to start through the control button on the handle, so that the mounting frame is adjusted to an appropriate height through the sliding rod. Then loosen the locking sleeve, and drive the fixing block and the rotating shaft to rotate through the handle and the connecting frame, thereby facilitating the adjustment of the drilling angle of the drill gun. Then lock the locking sleeve again to fix the angle. Start the drill gun, and then start the second electric push rod through the control button, so that the drill gun obtains an upward thrust during drilling, greatly reducing the fatigue of the arm.

[0014] 2. By using the support legs at the lower end of the bottom frame that slope outward and the top plate, it is convenient to fix the bottom frame and maintain the stability of the sliding rod and the mounting frame connected to the upper end.

The mounting frame 2 is set as a U-shaped frame structure. And the locking sleeves 21 are arranged on the outside of the mounting frame 2. And the locking sleeves 21 are threadedly connected with both ends of the rotating shaft 24. The middle of the rotating shaft 24 is connected with a fixing block 25. And a positioning cylinder 22 is fixed at the upper end of the fixing block 25. And a thrust rod 23 is slidably inserted into the upper end of the positioning cylinder 22. The drill gun 3 is connected to the upper end of the thrust rod 23. The lower end of the fixing block 25 is welded with a connecting frame 26. And handles 27 are arranged at both lower ends of the connecting frame 26. And a second electric push rod 28 is installed inside the connecting frame 26.

[0022] In this embodiment, the bottom frame 1, the mounting frame 2 and the drill gun 3 constitute the main structure of the top drilling device for building construction involved in this application.

[0023] In this embodiment, both ends of the rotating shaft 24 are provided with threaded sections, and corresponding nuts are provided at the inner ends of the locking sleeves 21.

[0024] Specifically, the connecting frame 26 includes a horizontal plate on the upper side, and an inclined rod is connected to the lower end of the horizontal plate. And a cross bar is connected to the lower end of the inclined rod, and handles 27 are provided at both ends of the cross bar.

[0025] As a preferred implementation manner, the double-handle 27 structure is realized by setting the connecting frame 26, thereby facilitating the holding of the drill gun 3, ensuring that the drilling angle does not deviate, and preventing the phenomenon of drill bit breakage.

[0026] Specifically, the telescopic rod body of the second electric push rod 28 slides upward through the fixed block 25 and inserts into the positioning cylinder 22. And the telescopic rod is connected to the lower end of the ejector rod 23.
