[0027] When using this device, first connect the cleaning brush 5 to the drill bit 2, and insert the cleaning brush 5 into the tension bolt hole. Start the motor 3 to drive the drill bit 2 to rotate, and the cleaning brush 5 rotates accordingly to clean the tension bolt hole. After cleaning, take out the device, remove the cleaning brush 5, use the connecting assembly 4 to connect the grouting hose 61 and the drill bit 2, start the grouting pump 6 to flow the slurry from the slurry storage device through the grouting hose 61 and the insert grouting hole 22 of the drill bit 2 into the tension bolt hole for plugging. The drill bit 2 is in the center for grouting, which can effectively make the plugging concrete uniform and improve the plugging quality. In addition, this device can also be used as a drilling device in the early stage, using a drill bit to drill holes, which improves the utilization rate of the device without the need for additional devices.

[0028] like Figure 3 and Figure 4 As shown, as a preferred embodiment, it also includes a hollow box 1, a motor 3 is arranged on the inner bottom surface of the hollow box 1, and the output shaft of the motor 3 is connected to a driving gear 31; the tail of the drill bit 2 is inserted into the hollow box 1, and a driven gear 21 is sleeved thereon, and the driven gear 21 is meshed with the driving gear 31. In this embodiment, the motor 3 is started, and the output shaft of the motor 3 rotates to drive the driving gear 31 to rotate. Since the driving gear 31 is meshed with the driven gear 21, the driven gear 21 rotates to drive the drill bit 2 to rotate, thereby realizing operations such as drilling or cleaning.

[0029] like Figure 3 and Figure 6As shown in the figure, as a preferred embodiment, the connecting assembly 4 includes a left guide structure 41, a right guide structure 42, a guide sleeve 43, an upper horizontal bracket 44, a lower horizontal bracket 45 and a reduction motor 46; the upper horizontal bracket 44 and the lower horizontal bracket 45 have the same structure and are arranged on the inner wall of the hollow box body 1; the left guide structure 41 includes a left conveying pressure wheel 411 and a left gear 412, the upper end of the left conveying pressure wheel 411 is rotatably connected to the lower part of the upper horizontal bracket 44, and the lower end is rotatably connected to the upper part of the lower horizontal bracket 45; the left gear 412 is rotatably arranged at the lower part of the lower horizontal bracket 45, and the left conveying pressure wheel 411 is rotatably connected to the lower part of the upper horizontal bracket 44. The bottom of the rotating shaft of the wheel 411 passes through the lower horizontal bracket 45 and is connected to the left gear 412 to drive the left gear 412 to rotate; the right guide structure 42 is the same as the left guide structure 41, including a right conveying pressure wheel 421 and a right gear 422, which are symmetrically arranged on the right side, and the right gear 422 is meshed with the left gear 412; the output shaft of the reduction motor 46 is connected to the rotating shaft of the left conveying pressure wheel 411; the left end of the guide sleeve 43 is connected to the drill bit 2, and the right end is provided with a docking joint 431; the grouting hose 61 passes through the inner side of the hollow box 1 and is conveyed and connected to the docking joint 431 via the left conveying pressure wheel 411 and the right conveying pressure wheel 421. In this embodiment, when using this device, when grouting operation is required, the reduction motor 46 is started to drive the left conveying pressure wheel 411 to rotate. Since the left gear 412 is connected to the left conveying pressure wheel 411, the left gear 412 is driven to rotate. Since the left gear 412 is meshed with the right gear 422, the right gear 422 is driven to rotate, thereby driving the right conveying pressure wheel 421 to rotate. The end portion of the grouting hose 61 is squeezed by the left conveying pressure wheel 411 and the right conveying pressure wheel 421 and driven to move forward, and is connected to the docking joint 431. The pipe diameter of the docking joint 431 is slightly larger than the grouting hose 61, which facilitates the insertion of the grouting hose 61 and smoothly enters the insertion grouting hole 22 in the drill bit 2, thereby ensuring the stability and accuracy of the conveying process. The upper horizontal bracket 44 and the lower horizontal bracket 45 serve as the installation basis to improve the stability of the device.

[0030] like Figure 4 As shown, as a preferred embodiment, it also includes a first support plate 7, which is vertically arranged at the top of the hollow box body 1, and the guide sleeve 43 passes through the first support plate 7 for support. In this embodiment, the first support plate 7 is arranged in the hollow box body 1, and the guide sleeve 43 passes through the first support plate 7 to bear the weight, stabilize the position of the guide sleeve 43, and improve stability.

[0031] like Figure 4 As shown, as a preferred embodiment, a plurality of first support plates 7 are provided in parallel. In this embodiment, a plurality of first support plates 7 are provided to jointly bear the weight of the guide sleeve 43, and the connection is more stable.

In this embodiment, since the motor 3 and the drill bit 2 will rotate during operation, in order to ensure that the driving gear 31 and the driven gear 21 are always engaged, the second support plate 8 is provided to fix the output shaft of the drill bit 2 and the motor 3, thereby improving the stability of the device.

[0033] like Figure 4 As shown, as a preferred embodiment, the motor 3 is arranged on the inner bottom surface of the hollow box 1. Specifically, a support seat 9 is provided at the bottom of the motor 3, and the support seat 9 is connected to the inner bottom surface of the hollow box 1. In this embodiment, since the motor 3 will vibrate slightly when working, the support seat 9 can prevent the motor 3 from moving.

[0034] like Figure 5 As shown, as a preferred embodiment, the annular surface of the drill bit 2 is provided with multiple groups of cutting blades 23. The drill bit 2 uses the cutting blades 23 to cut when drilling holes, thereby improving the drilling effect.

[0035] like Figure 7 As shown, as a preferred embodiment, the rear end of the cleaning brush 5 is further provided with a baffle 51 and a plug connector 52; the plug connector 52 is detachably inserted into the plug-in grouting hole 22 at the front end of the drill bit 2, and the baffle 51 is sleeved on the plug connector 52. In this embodiment, the plug connector 52 is inserted into the plug-in grouting hole 22 for connection, and the baffle 51 limits the insertion depth during connection to avoid over-insertion affecting use.

[0036] like Figure 1 and Figure 2 As shown, as a preferred embodiment, a gripping handle 10 is provided at the bottom of the hollow box 1. In this embodiment, when the device is used for cleaning and grouting, the operator can hold it by the gripping handle 10 for easy operation.
