[0002] Grouting hole devices for coal mine faults are mainly used to drill grouting holes in fractured fault areas and fill the holes with reinforcing materials to strengthen the mine pit and prevent water inrush or collapse accidents. However, due to the loose rocks and numerous fissures in fault zones, the traditional method is for miners to enter the mine shaft and drill holes with ordinary drilling rigs. However, this often encounters problems in practice, such as easy deviation in drilling position, grout flowing to unnecessary areas leading to material waste, high gas content in coal mine faults, and the potential for gas leaks, producing smoke, dust, and toxic gases that are flammable and explosive, causing harm to humans. Furthermore, the complex fissures in fault zones make traditional equipment difficult to adapt to.

[0035] like Figure 1 As shown, the coal mine fault grouting hole device includes a support assembly 1, a position adjustment assembly 2, a drilling assembly 3, a counterweight assembly 4, four hydraulic outriggers 5, and a lighting assembly 6. The support assembly 1 is used to support the main structure. The position adjustment assembly 2 is located on the upper end of the support assembly 1 and enables the device to drill holes in different directions of the coal mine fault. The drilling assembly 3 is located on the position adjustment assembly 2 and can drill grouting holes at the coal mine fault.

The lighting assembly 6 is located on the support assembly 1 and is used for illumination.
[0036] like Figure 2 As shown, the support assembly 1 includes a support plate 11, a power unit 12 and a non-powered unit 13.

The controller is activated inside the mine pit. The controller transmits a signal to the rotary motor 123. The rotary motor 123 is a prior art technology. The model of the rotary motor 123 is Siemens 1LE1. The rotating shaft of the rotary motor 123 drives the first wheel shaft 122 to rotate. The first wheel shaft 122 drives the power wheel 121 to move. Under the action of ground friction, the non-powered wheel 131 will also rotate, thereby controlling the overall device to move forward or backward and find the approximate location of the grouting hole to be drilled in the mine pit.
[0038] like Figure 4 As shown, the position adjustment assembly 2 includes two first U-shaped slide rails 21, a first slider 22, a first linear module 23, a mechanical rotary table 24, and a support plate 25. The two first U-shaped slide rails 21 are parallel to each other and arranged opposite each other. The lower end of each first U-shaped slide rail 21 is fixedly connected to the support plate 11. Each first U-shaped slide rail 21 has a first groove 211 along the axial direction. The two sides of the first slider 22 are slidably connected in the two first grooves 211. The lower end of the first slider 22 is fixedly connected to the movable end of the first linear module 23. The first linear module 23 is fixedly installed on the support plate 11. One end of the mechanical rotary table 24 is fixedly connected to the first slider 22, and the other end of the mechanical rotary table 24 is fixedly connected to the support plate 25. The mechanical rotary table 24 can drive the support plate 25 to rotate. When the controller is activated, it transmits signals to the first linear module 23 and the mechanical rotary table 24. The first linear module 23 is a telescopic cylinder, which is existing technology and its model is SMCCDJ2. The mechanical rotary table 24 is also existing technology and its model is CSG-25-100-2UH. The linear module 23 can adjust the vertical position of the drilling assembly 3 by telescopic movement, and the mechanical rotary table 24 can rotate the drilling assembly 3. This allows the device to drill holes not only on horizontal ground but also on the inner wall of the mine pit, achieving the purpose of accurately determining the drilling position.
[0039] like Figure 5As shown, the drilling assembly 3 includes two second U-shaped slide rails 31, a second slider 32, a second linear module 33, a drilling unit 34, a first metal plate 35, two second metal plates 36, a third metal plate 37, two U-shaped metal plates 38, and two third linear modules 39. The two second U-shaped slide rails 31 are parallel to each other and arranged opposite each other. The lower end of each second U-shaped slide rail 31 is fixedly connected to both ends of the first metal plate 35, and the outer side of each second U-shaped slide rail 31 is fixedly connected to the support plate 25. Each second U-shaped slide rail 31 has a second groove 311 along the axial direction. The second slider 32... The two sides are slidably connected in two second slide grooves 311. The lower end of the second slider 32 is fixedly connected to the movable end of the second linear module 33. The second linear module 33 is fixedly connected to the first metal plate 11. Two second metal plates 36 are arranged parallel to each other. A second metal plate 36 is set at each end of the first metal plate 35. A third metal plate 37 is set between the second metal plates 36. Two C-shaped metal plates 38 are arranged opposite each other. The outer side of each C-shaped metal plate 38 is fixedly connected to the movable end of each third linear module 39. Each third linear module 39 is fixedly connected to a second metal plate 36.
[0040] like Figure 6 As shown, the drilling unit 34 includes a support plate 341, a rotary power head 342, a connector 343, a drill bit 344, and multiple drill rods 345. The support plate 341 is disposed on the second slider 32. The rotary power head 342 is fixedly installed on the support plate 341. One end of the connector 343 is fixedly connected to one end of the rotary power head 342, and the other end of the connector 343 is threaded. One end of the drill bit 344 is threaded to the connector 343. The drilling unit 34 also includes a plurality of drill rods 345, and one end of each drill rod 345 is fixedly connected to one end of an adjacent drill rod 345 or a connector 343. The other end of each drill rod 345 is fixedly connected to one end of an adjacent drill rod 345 or one end of a drill bit 344.
[0041] Upon reaching the predetermined drilling position, the controller controls the linear module 23 to move, causing the first slider 22 to move along the first groove 211 towards the drilling position, bringing the drilling assembly 3 to the desired drilling position and stabilizing the drilling unit 34. The rotary power head 342 (a prior art model, ABBM3BP) is then activated. The rotary power head 342 rotates, causing the connector 343 to rotate clockwise. The rotation of the connector 343 causes the drill bit 344 to rotate. Simultaneously, the second linear module 33 retracts, causing the second slider 32 to move along the second groove 311, thus moving the rotary power head 342 and the drill bit towards the drilling position to achieve the drilling purpose. Because the drill bit 344 has a threaded structure, the generated soil can be transported along the threads to the outside of the borehole. When the drill bit 344 is almost completely submerged in the grouting hole, two third linear modules 39 are activated. Both the second and third linear modules 39 are telescopic cylinders, which are existing technology. The model of the telescopic cylinder 39 is CDJ2B10-15. The movable end of the third linear module extends, driving the U-shaped metal plate 38 to move towards the drill bit 344 and clamping the drill bit 344. At this time, the rotating power head 342 rotates counterclockwise and the second linear module 33 retracts. Since the drill bit 344 is fixed and the second slider 32 moves away from the grouting hole, the drill bit 344 will separate from the joint 343. At this time, the lower end of a drill rod 345 is threaded onto the drill bit 344. The second linear module 33 is controlled to extend and the rotating power head 342 is controlled to rotate clockwise. The joint 343 will be threaded onto the upper end of the drill rod 345. The third linear module 39 is controlled to retract, and the U-shaped metal plate 38 releases the drill bit 344 so that drilling can continue. Repeating the above process can drill deeper grouting holes in coal mine faults.
[0042] The support plate 341 is a metal plate covered with sponge and has a round hole in the middle. The rotating power head 342 is fixedly installed in the round hole of the support plate 341. The support plate 341 can not only fix the rotating power head 342, but also absorb the vibration generated during drilling, reduce the overall shaking of the device, stabilize the structure, and improve safety.
[0043] like Figure 7As shown, the counterweight assembly 4 includes a bucket 41, a handle 42, a non-slip grip 43, five partition plates 44, and a limiting groove 45. The limiting groove 45 is fixedly installed on the support plate 11. The bucket 41 is placed in the limiting groove 45. The handle 42 is hinged to both sides of the bucket 41. The non-slip grip 43 is rotatably connected to the handle 42. The five partition plates 44 are arranged parallel to each other and fixedly connected inside the bucket. The five partition plates 44 are used to divide the space inside the bucket 41 into six independently arranged water tanks 46. Each water tank 46 can be filled with water. The water bucket has a capacity of 60L. Five partition plates 44 divide the water bucket 41 into 6 water tanks 46, each with a capacity of 10L. The amount of water tank 46 filled can be selected to change the weight of the counterweight. Each water tank filled with counterweight is 10kg, which changes the grip of the driving wheel 121 and the non-driving wheel 131, thereby allowing the entire device to move smoothly in the mine. At the same time, in the event of a gas leak or encounter with an open flame, the handle 42 can be lifted to extinguish the fire and suppress smoke and dust. The lighting component 6 is a prior art technology. The model of the lighting component 6 is JW7620, which can provide lighting and also has an explosion-proof function, reducing the occurrence of dangerous factors.
[0044] like Figure 8 As shown, the hydraulic outrigger 5 includes a hydraulic rod 51 and a base 52. The hydraulic rod 51 is fixedly connected to the lower end of the support plate 11, and the movable end of the hydraulic rod 51 is fixedly connected to the base 52. The hydraulic rod 51 is existing technology, and the model of the hydraulic rod 51 is XZ200-5. When the device reaches the predetermined drilling position, the hydraulic rod 51 is activated, and the hydraulic outrigger 5 can support the device and fix it on the ground, thus stabilizing the whole device.
[0045] Working process of coal mine fault grouting hole device:
[0046] A suitable amount of water is added to the counterweight assembly 4, and the controller is activated inside the mine. The controller transmits signals to the rotary motor 123 and the mine lamp 61 via wires, turning on the lighting and activating the rotary motor 123 to control the overall device to move forward or backward, finding the approximate location of the grouting hole to be drilled. After reaching the predetermined drilling position, the hydraulic rod 51 is activated, and the hydraulic outriggers 5 can support and fix the device to the ground. At this time, the controller transmits signals to the first linear module 23 and the mechanical rotary table 24. The mechanical rotary table 24 and the linear module 23 adjust the position of the drilling assembly 3 to find the specific location to be drilled. After determining the location, the linear module 23 is controlled to abut the drilling assembly 3 against the location to be drilled. After fixing, the rotating power head 342 is activated. 342 and the drill bit move towards the drilling position. When the drill bit 344 is almost completely submerged in the grouting hole, the two third linear modules 39 are activated. The rotating power head 342 rotates counterclockwise and the second linear module 33 retracts. Since the drill bit 344 is clamped and fixed, and the second slider 32 moves away from the grouting hole, the drill bit 344 will separate from the connector 343. At this time, the lower end of a drill rod 345 is threaded to the upper end of the drill bit 344. The second linear module 33 is extended and the rotating power head 342 is rotated clockwise. The threaded head of the connector 343 will be threaded to the upper end of the drill rod 345. At this time, the third linear module 39 is retracted and the C-shaped metal plate 38 releases the drill bit 344 so that drilling can continue. Repeating the above process can drill deeper grouting holes in coal mine faults.
[0047] The control method in this embodiment is controlled by a controller. The controller circuit can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this document is mainly used to protect mechanical devices, and the control method and circuit connection will not be explained in detail here.
[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
