Detailed Implementation

[0024] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0025] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0026] Example 1

[0027] An external wall drilling device, such as Figure 1-5 As shown, the system includes an installation frame 1. A set of guide columns 4 are fixed to the inner wall of the installation frame 1. A movable frame 15 is slidably connected to the outer wall of the guide columns 4. The movable frame 15 is slidably connected to the inner wall of one side of the installation frame 1. A drive motor 16 is fixed to the inner wall of the movable frame 15. The output shaft of the drive motor 16 is connected to a drill rod 10 through a coupling. A set of fixing plates 8 are fixed to the outer wall of one side of the installation frame 1. A set of elastic telescopic rods 9 are fixed to the outer wall of the fixing plates 8. A shield 12 is fixed to the telescopic end of the elastic telescopic rods 9. A round hole is opened on the outer wall of the shield 12. A sleeve 11 is fixed to the inner wall of the round hole. The drill rod 10 passes through the shield 12 through the sleeve 11.

[0028] A friction pad 18 is fixed to one outer wall of the mounting frame 1;

[0029] The outer wall of the movable frame 15 is fixed with a first handle 14, and a set of support plates 3 is fixed on one side of the outer wall of the mounting frame 1. The outer wall opposite to the support plate 3 is fixed with a second handle 19.

[0030] The operator can use the second handle 19 and the first handle 14 to move the drilling device to the corresponding drilling position on the exterior wall. Then, the friction pad 18 and the shield 12 at one end of the mounting frame 1 are pressed against the exterior wall. At this time, the shield 12 will be tightly pressed against the exterior wall by the elastic force of the elastic telescopic rod 9. Simultaneously, one side of the mounting frame 1 can be stably pressed against the exterior wall by the friction between the friction pad 18 and the exterior wall. Then, the operator uses one hand to press the entire mounting frame 1 against the exterior wall using the second handle 19, and the other hand to push the movable frame 15 forward using the first handle 14, thereby allowing the drilling to proceed through the drive motor. The machine 16 drives the rotating drill rod 10 forward. After the drill rod 10 passes through the sleeve 11, it can contact the outer wall and thus drill forward under the push of the first handle 14. At this time, the entire mounting frame 1 can be stably pressed against one side of the outer wall under the action of the push of the second handle 19 and the friction between the friction pad 18 and the outer wall. This allows the drill rod 10 to move vertically forward under the guidance of the movable frame 15 and the guide column 4, improving the stability of the drilling device during drilling. At the same time, the shield 12 can shield the drilling area of ​​the outer wall to prevent the debris generated during drilling from flying out.

[0031] like Figure 1 As shown, the outer wall of the shield 12 is fixed with an elastic sealing edge 13; the elastic sealing edge 13 can improve the sealing performance between the shield 12 and the contact surface of the outer wall.

[0032] like Figure 1-3 As shown, the top outer wall of the mounting frame 1 has multiple insertion holes 5, and insertion rods 7 are inserted into the inner wall of the insertion holes 5.

[0033] The outer wall of the mounting frame 1 is provided with a scale 2;

[0034] The top outer wall of the insertion rod 7 is fixed with an ear plate 6, and the bottom inner wall of the mounting frame 1 is fixed with multiple slots 17. The bottom end of the insertion rod 7 is inserted into the inner wall of the slot 17.

[0035] Workers can insert the insertion rod 7 into the corresponding insertion hole 5 on the outer wall of the mounting frame 1 according to the drilling needs. After the movable frame 15 moves forward a corresponding distance, the insertion rod 7 can block the movable frame 15 and precisely adjust the distance that the drill rod 10 drills forward, thus improving the overall applicability of the drilling mechanism.

[0036] The drilling mechanism used in this embodiment, consisting of a drive motor 16 and a drill rod 10, is one of the commercially available drilling devices consisting of a drilling motor and a drill rod. This drilling device is a mature existing technology.

[0037] Working principle: The operator can hold the second handle 19 and the first handle 14 to move the drilling device to the corresponding drilling position on the outer wall. Then, the friction pad 18 and the shield 12 at one end of the mounting frame 1 are pressed against the outer wall. At this time, the shield 12 will be pressed tightly against the outer wall under the elastic force of the elastic telescopic rod 9. At the same time, one side of the mounting frame 1 can be stably pressed against the outer wall by the friction between the friction pad 18 and the outer wall. Then, the operator uses the second handle 19 to press the entire mounting frame 1 against the outer wall with one hand, and pushes the movable frame 15 forward with the first handle 14 with the other hand, so that the drill rod 10 driven by the drive motor 16 moves forward. After the drill rod 10 passes through the sleeve 11, it can contact the outer wall and drill forward under the push of the first handle 14. At this time, the entire mounting frame 1 can be stably pressed against the outer wall by the push of the second handle 19 and the friction between the friction pad 18 and the outer wall, so that the drill rod 10 can move vertically forward under the guidance of the movable frame 15 and the guide post 4.

[0038] According to the drilling requirements, the insertion rod 7 can be inserted into the corresponding insertion hole 5 on the outer wall of the mounting frame 1. After the movable frame 15 moves forward a corresponding distance, the insertion rod 7 can block the movable frame 15 and precisely adjust the distance that the drill rod 10 drills forward.

[0039] Example 2

[0040] An external wall drilling device, such as Figure 4-5 As shown, this embodiment makes the following improvements based on embodiment 1: a slot plate 20 is inserted into the outer wall of the mounting frame 1, and a telescopic rod 21 is fixed to the bottom outer wall of the slot plate 20. A support pad 22 is fixed to the telescopic end of the telescopic rod 21. According to the drilling requirements, the operator can insert a set of slot plates 20 into one side of the mounting frame 1, and the mounting frame 1 can be supported by the two telescopic rods 21 and the support pad 22. Then, the movable frame 15 can be easily pushed back and forth to drill holes in the outer wall, further improving the convenience of using the drilling device. The telescopic rod 21 used in this embodiment is a commercially available telescopic rod whose telescopic length can be fixed by screws or other structures, which is a mature existing technology.

[0041] Working principle: According to the drilling construction requirements, the staff can insert a set of slot plates 20 into one side of the mounting frame 1, and the mounting frame 1 can be supported by two telescopic rods 21 and support pads 22.
