[0020] The present invention will be further described below in conjunction with the embodiments given in the accompanying drawings.

[0021] Reference Figure 1-4As shown, a lifting device for drilling holes in a ceiling comprises a mobile base 1, a jack 2 mounted on the mobile base 1, a first placement plate 3, a second placement plate 4, an electric hammer frame 5, an electric push cylinder 6, and a plurality of vertical poles 7. The plurality of vertical poles 7 are arranged in a rectangular shape around the jack 2. The electric push cylinder 6 and the electric hammer frame 5 are respectively mounted on the first placement plate 3 and the second placement plate 4. The first placement plate 3 and the second placement plate 4 are mounted on the vertical pole 7 and can move along the height direction of the vertical pole 7. An abutment component is sleeved on the top of the vertical pole 7. The abutment component is used to abut the ceiling, and the entire device is supported between the ceiling and the ground through a reverse force. The abutment component comprises an abutment plate 9 and a movable column 10. The abutment plate 9 is ball-jointed to the top of the movable column 10. The movable column 10 is provided with an inner hole and sleeved on the vertical pole 7 through the inner hole. The second placement plate 4 is provided with a limiting ring 8 at a position corresponding to the movable column 10. The limiting ring 8 is provided with a movable groove 11 for inserting the movable column. The movable column 10 extends into the limiting ring 8 and can slide along the height of the limiting ring 8. The limiting ring 8 is provided with a flange to prevent the movable column 10 from falling out. A first spring 12 for ejecting the movable column 10 is provided between the movable column 10 and the second storage plate 4. The jack 2 is installed on the lowest layer to provide reliable support for the whole. The first storage plate 3 is installed on the upper end of the jack 2, and the second storage plate 4 is installed on the upper end of the electric push cylinder 6. The electric push cylinder 6 is installed on the second layer for quick height adjustment. When approaching the height of the ceiling, the jack 2 is adjusted to provide a stable and reliable drilling thrust for the electric hammer, so that the first spring 12 in the limiting ring is compressed by pressure, so that the abutment assembly is stably supported on the ceiling. As the first spring 12 is forced to contract, the height of the second storage plate 4 is lifted upward, and the drill bit of the electric hammer installed on the electric hammer frame 5 begins to abut against the ceiling for drilling. The abutment plate 9 connected with a ball joint can not only adapt to the flat ceiling but also can stably drill the inclined ceiling.

[0022] A threaded sleeve 13 is provided at the position of the bottom 4 of the second storage plate corresponding to the limit ring 8. The threaded sleeve 13 is sleeved on the vertical pole 7 and passes through the second storage plate 4 and is threadedly connected to the inner wall of the limit ring 8. One end of the first spring 12 abuts against the movable column 10, and the other end thereof abuts against the threaded sleeve 13. A scale mark is provided at the shaft section of the vertical pole 7 corresponding to the activity of the threaded sleeve 13. A second spring 23 is installed between the top of the vertical pole and the inner hole of the movable column along the axial direction. The threaded sleeve 13 sleeved on the vertical pole 7 is rotated to compress the first spring 12 to provide a pre-tightening force. This arrangement enables it to provide reliable supporting force even when facing some shallower holes. The scale on the vertical pole 7 can cooperate with the construction personnel to read the readings to observe the depth of the drilling. The second spring 23 is provided to further improve the stability of the overall abutment.

[0023] The abutment plate 9 is also provided with a dustproof component for collecting dust, and the dustproof component is provided for collecting debris and dust scattered during the drilling process. The dustproof component includes a dustproof cloth 24 and a throat hoop 25. The dustproof cloth 24 is provided with an annular notch, and the throat hoop 25 is fixedly connected at the annular notch. Counterweight blocks 26 are arranged at the four corners of the dustproof cloth 24. The abutment plate 9 is provided with a wire groove 27 for the dustproof cloth 24 to be inserted. During installation, the hoop 25 is sleeved on the outer cylindrical surface of the front end of the electric hammer, and the notch of the dustproof cloth 25 is tightly attached to the front end of the electric hammer by locking the throat hoop 25. The four corners of the dustproof cloth 25 are inserted into the wire groove 27 of the abutment plate 9 and are connected by the counterweight blocks. Block 26 prevents the four corners of the dustproof cloth 24 from slipping out of the wire groove 27. Since the middle part of the dustproof cloth is fixed on the outer cylindrical surface of the front end of the electric hammer, its four corners are plugged into the wire groove 27, so a concave shape is formed in the middle, which is convenient for collecting scattered debris and dust. When the dustproof cloth 24 needs to be cleaned after the electric hammer has worked continuously, the overall height is first lowered, the electric hammer is disassembled, and then the counterweight block 26 is grabbed to pull the dustproof cloth 24 out from the opening of the wire groove 27 of the abutment plate 9, and the four corners of the dustproof cloth 24 are lifted, and the electric hammer and the dustproof cloth are taken away to dump the dust. After cleaning, continue to install and fix the electric hammer, and then install the four corners of the dustproof cloth 24.

[0024] The electric hammer frame 5 is provided with a window 14 for tying a throat clamp, and a side plate 15 rotatably connected to the electric hammer frame 5 is provided on one side of the electric hammer frame 5. The second storage plate 4 is provided with an open groove corresponding to the swing direction of the side plate 15, and a driving component is provided in the open groove. The driving component is used to control the expansion angle of the side plate 15 and limit it, and can fine-tune the angle of the electric hammer so that it can better drill vertically with the ceiling and reduce the occurrence of skewed holes. The driving component includes a bearing seat 16, a screw rod 17, and a slide seat 18 installed on the screw rod 17. The bearing seat 16 is fixedly connected to the opening, and the screw 17 is installed on the bearing seat 16. A push plate 19 hinged to the side plate 15 is provided on the slide seat 18. The width of the slide seat 18 matches the open groove, so that it can perform linear motion under the push of the screw rod 17, and the push rod on the slide seat 18 can adjust the swing angle of the side plate 15 and limit it as the slide seat 18 moves.

[0025] To facilitate the installation and transportation of the vertical pole 7, the vertical pole 7 is divided into several sections, and mutually matching threaded columns and threaded holes are respectively provided between adjacent vertical poles 7. A stabilizing frame is installed between the vertical poles 7 on the same side of the jack 2, and the stabilizing frame includes a collar 20, a connecting rod 21, and an inclined rod 22. The collar 20 is installed on the vertical pole 7, the connecting rod 21 is used to fix adjacent collars 20, and the inclined rod 22 is used to connect the mobile base 1 and the collar 20. The stability of the vertical pole 7 is further improved by setting a stabilizing frame. The mobile base 1 is provided with a handrail, and the bottom of the handrail is fixedly connected to the mobile base 1 in a herringbone shape. In this embodiment, the handrails are arranged in pairs on both sides of the mobile base 1 to facilitate movement by construction personnel.
