Description

Technical Field

[0001] This utility model relates to the field of underground coal mine engineering technology, and in particular to a drilling grouting device with anti-clogging effect. Background Technology

[0002] In underground coal mine engineering, drilling and grouting technology is one of the commonly used core technologies. It involves drilling a hole in the surrounding rock of the roadway using drilling equipment, and then injecting grout into the hole using a grouting device. After the grout fills the voids in the surrounding rock and solidifies, it can effectively improve the stability of the roadway or achieve the effect of plugging leaks.

[0003] Existing drilling grouting devices typically involve manually inserting a grouting pipe into the borehole and then injecting grout into the borehole through the grouting pipe. However, since the grouting pipe needs to be manually fixed to maintain stability, it is labor-intensive and difficult to ensure the stability of the grouting pipe. In addition, it is impossible for humans to observe the grouting situation inside the borehole and to stop grouting in time, which can easily lead to insufficient or excessive grouting.

[0004] Therefore, a drilling grouting device with anti-clogging effect has now been developed, which can fix the grouting pipe and unlock it to push it out when grouting is completed, reminding personnel to stop grouting in time. Utility Model Content

[0005] To overcome the shortcomings of existing drilling grouting devices, such as the need for manual fixing of the grouting pipe to maintain stability, which is labor-intensive and makes it difficult to ensure the stability of the grouting pipe, and the inability of personnel to observe the grouting situation inside the borehole and stop grouting in time, resulting in insufficient or excessive grouting, this utility model provides a drilling grouting device that can fix the grouting pipe and unlock it to push it out when grouting is completed, reminding personnel to stop grouting in time, and has an anti-clogging effect.

[0006] The technical solution of this utility model is: a drilling grouting device with anti-clogging effect, including a connecting pipe, a fixing frame, a grouting pipe, a spiral rod, a first spring, a limiting component, and an unlocking component. The fixing frame is connected to the upper part of the connecting pipe, the grouting pipe is slidably connected inside the connecting pipe, the spiral rod is rotatably connected inside the grouting pipe, the connecting frame is connected to the upper part of the grouting pipe, the first spring is connected between the connecting frame and the fixing frame, the fixing frame is provided with a limiting component for limiting the connecting frame, and the connecting pipe is provided with an unlocking component for unlocking the connecting frame.

[0007] Furthermore, the mounting bracket has multiple mounting holes.

[0008] Furthermore, a threaded joint is provided on the upper side of the grouting pipe.

[0009] Furthermore, the limiting component includes a locking frame and a third spring. The locking frames are slidably connected to both the left and right sides of the fixed frame. The connecting frame and the locking frames are pressed together. The locking frames are connected to the fixed frame by a third spring.

[0010] Furthermore, the unlocking component includes a connecting plate, a connecting post, a second spring, a sliding post, and a connecting rod. The connecting tube is slidably connected to the connecting post on both the left and right sides. A connecting plate is connected between the lower sides of the connecting post. A second spring is connected between each connecting post and the connecting tube. The upper left and right sides of the connecting tube are slidably connected to the sliding post. A connecting rod is rotatably connected to the upper side of each sliding post. The connecting rod is rotatably connected to the adjacent locking frame.

[0011] Furthermore, limit blocks are provided on the lower side of each sliding column.

[0012] The beneficial effects are: 1. When the grout fills the grouting pipe, the connecting plate is pushed upward, causing the connecting column to move upward. The second spring is compressed and contracted. At this time, the connecting column pushes the sliding column upward, causing the connecting rod to pull the locking frame away from each other and no longer restrict the connecting frame. Then the first spring rebounds, causing the grouting pipe to move upward, reminding the personnel to stop grouting, thus achieving the effect of avoiding insufficient or excessive grouting.

[0013] 2. When the connecting frame of this utility model moves to the positioning frame, the positioning frames are squeezed away from each other, and the third spring is compressed and contracted. After the connecting frame moves to the bottom of the positioning frame, the third spring rebounds, so that the positioning frame is reset and the connecting frame is fixed, thereby fixing the grouting pipe. This achieves the effect of avoiding the grouting pipe from shifting or shaking, which would affect the uniformity of grout diffusion. Attached Figure Description

Detailed Implementation

[0017] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0018] A drilling grouting device with anti-clogging effect, such as Figure 1 and Figure 2As shown, it includes a connecting pipe 1, a fixing frame 2, a grouting pipe 3, a spiral rod 4, a connecting frame 5, a first spring 6, a limiting component, and an unlocking component. The fixing frame 2 is connected to the upper part of the connecting pipe 1. The fixing frame 2 has six mounting holes for easy installation and fixing. The grouting pipe 3 is slidably connected inside the connecting pipe 1. The upper side of the grouting pipe 3 is provided with a threaded joint for easy connection to the grout delivery pipeline. The spiral rod 4 is rotatably connected inside the grouting pipe 3. The connecting frame 5 is connected to the upper part of the grouting pipe 3. The first spring 6 is connected between the connecting frame 5 and the fixing frame 2. The fixing frame 2 is provided with a limiting component, and the connecting pipe 1 is provided with an unlocking component.

[0019] like Figure 1 and Figure 2 As shown, the limiting component includes a locking frame 10 and a third spring 11. The locking frame 10 is slidably connected to both the left and right sides of the fixed frame 2. The connecting frame 5 is pressed and engaged with the locking frame 10. The locking frame 10 is connected to the fixed frame 2 by a third spring 11.

[0020] like Figure 1 and Figure 2 As shown, the unlocking assembly includes a connecting plate 7, a connecting post 8, a second spring 9, a sliding post 12, and a connecting rod 13. The connecting tube 1 is slidably connected to the connecting post 8 on both the left and right sides. The connecting plate 7 is connected between the lower sides of the connecting post 8. The second spring 9 is connected between the connecting post 8 and the connecting tube 1. The upper left and right sides of the connecting tube 1 are slidably connected to the sliding post 12. The lower side of the sliding post 12 is provided with a limit block for easy positioning. The upper side of the sliding post 12 is rotatably connected to the connecting rod 13. The connecting rod 13 is rotatably connected to the adjacent locking frame 10.

[0021] When using this utility model, firstly, the connecting pipe 1 is placed into the borehole. At this time, the fixing frame 2 is in contact with the ground. Then, the fixing frame 2 is fixed on the ground, and then the grouting pipe 3 is connected to the grout delivery pipe through the threaded joint. During grouting, the grouting pipe 3 is pushed downwards to pass through the connecting plate 7, the connecting frame 5 moves downwards, the first spring 6 is compressed and contracted, when the connecting frame 5 moves to the locking frame 10, the locking frames 10 are squeezed away from each other, the third spring 11 is compressed and contracted, after the connecting frame 5 moves below the locking frame 10, the third spring 11 rebounds, so that the locking frame 10 is reset, the connecting frame 5 is fixed, and then the grouting pipe 3 is fixed, thereby preventing the grouting pipe 3 from shifting or shaking, which would affect the uniformity of grout diffusion; Grout is then delivered into the grouting pipe 3 through the grout delivery pipe, filling the borehole with grout. When the grout enters the grouting pipe 3, it impacts the spiral rod 4, causing the spiral rod 4 to rotate and deliver the grout, preventing grout blockage. When the grout fills the grouting pipe 3, it pushes the connecting plate 7 upward, causing the connecting column 8 to move upward. The second spring 9 is compressed and contracts. At this time, the connecting column 8 pushes the sliding column 12 upward, causing the connecting rod 13 to pull the positioning frame 10 away from each other, no longer restricting the connecting frame 5. Subsequently, the first spring 6 rebounds, causing the grouting pipe 3 to move upward, reminding personnel to stop grouting, thus avoiding insufficient or excessive grouting. After the connecting pipe 1 is removed, the second spring 9 rebounds, causing the connecting plate 7 and connecting column 8 to reset, and then causing the sliding column 12, connecting rod 13, and positioning frame 10 to reset.
