Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a rapid handling device for drill pipe jamming and drill bit burial accidents in coal mines. Background Technology

[0002] Coal mines are areas where humans extract coal resources in coal-rich areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, tunnels are typically dug underground to extract the coal; this is called an underground coal mine. When the coal seam is very close to the surface, the surface soil is typically stripped away to extract the coal; this is called an open-pit coal mine. Drill rods used underground in coal mines are mainly used for tasks such as releasing methane gas from the coal seam and exploring for water between tunnels.

[0003] However, the current method of horizontal drilling is generally used, which is prone to coal seam collapse, resulting in situations where the drill rod is buried or stuck, which is inconvenient to handle and will affect the normal operation of the work. Summary of the Invention

[0004] The purpose of this invention is to provide a rapid handling device for drill rod jamming and burial accidents in coal mines. This device solves the problem that existing methods, which generally use horizontal drilling, are prone to coal seam collapse, resulting in drill rod burial and jamming, which are inconvenient to handle and affect the normal operation of the mine.

[0005] To achieve the above objectives, the present invention provides a rapid handling device for drill pipe jamming and burial accidents in coal mines, comprising a control console, a drilling rig, a connecting rod, a drill pipe, and multiple sets of cleaning components. The drilling rig is mounted on the control console. The connecting rod is fixedly connected to the output end of the drilling rig. The drill pipe is connected to the connecting rod. The cleaning components include a telescopic rod, a return spring, a drill bit, a mounting base, and a guide ring. The guide ring is fixedly connected to the connecting rod and sleeved on the outer wall of the connecting rod. The connecting rod has a groove, and the mounting base is disposed within the groove. Both ends of the telescopic rod are fixedly connected to the connecting rod and the mounting base, respectively. Both ends of the return spring are fixedly connected to the connecting rod and the mounting base, respectively, and sleeved on the outer wall of the telescopic rod. The drill bit is fixedly connected to the mounting base and located on the outer wall of the mounting base.

[0006] The cleaning component further includes two limiting blocks, and the connecting rod also has a limiting groove. The two limiting blocks are symmetrically arranged on the outer side wall of the mounting base, and both limiting blocks are slidably connected to the connecting rod and are respectively located in the limiting groove.

[0007] The telescopic rod includes an inner rod and an outer cylinder. The outer cylinder is fixedly connected to the connecting rod and located in the groove. One end of the inner rod is slidably connected to the outer cylinder, and the other end of the inner rod is fixedly connected to the mounting base.

[0008] The rapid handling device for stuck drill pipe and buried drill accidents in coal mines also includes a flushing component, which is mounted on the control console.

[0009] The flushing assembly includes a water tank, a high-pressure water pump, a connecting pipe, and multiple nozzles. The connecting rod has a water collection chamber and multiple water supply pipes. The water tank and the high-pressure water pump are respectively mounted on the control console. The high-pressure water pump is connected to one end of the connecting pipe, and the other end of the connecting pipe is connected to the water collection chamber. The multiple nozzles are all fixedly connected to the connecting rod and are respectively connected to the corresponding water supply pipes.

[0010] The flushing assembly also includes an observation window, which is fixedly connected to the water tank and located on the outer wall of the water tank.

[0011] This invention discloses a rapid handling device for drill rod jamming and burial accidents in coal mines. During coal mine drilling operations, the drilling rig is controlled from the control panel. The drilling rig drives the drill rod to rotate, allowing it to drill through the coal seam. When the drill rod becomes buried or jammed, the device continues to advance, causing the drill bit on the mounting base to contact the rock. Since the rock's outer surface is often irregular, the return spring and the telescopic rod extend and retract within the groove, allowing the drill bit to contact the outer wall of the rock for better crushing. The crushed rock then moves away along the guide ring, preventing coal seam collapse that could halt the drill rod's operation. This device quickly resolves situations where the drill rod is buried or jammed, ensuring normal operation. Attached Figure Description

Detailed Implementation

[0020] The first embodiment is as follows:

[0021] Please see Figures 1-3 ,in Figure 1 This is a schematic diagram of the overall structure of the first embodiment. Figure 2 This is a cross-sectional view of the overall internal structure of the first embodiment. Figure 3 yes Figure 2 Enlarged view of a partial structure at point A. This invention provides a rapid handling device for stuck drill pipe 104 and buried drill accidents in coal mines, including a control console 101, a drilling rig 102, a connecting rod 103, a drill pipe 104, and multiple sets of cleaning components. Each cleaning component includes a telescopic rod, a return spring 105, a drill bit 106, a mounting base 107, a guide ring 108, and two limiting blocks 109. The telescopic rod includes an inner rod 110 and an outer cylinder 111.

[0022] In this specific embodiment, the drilling rig 102 is mounted on the control console 101. The connecting rod 103 is fixedly connected to the output end of the drilling rig 102, and the drill rod 104 is connected to the connecting rod 103. When drilling in a coal mine, the drilling rig 102 is controlled to operate on the control console 101. The drilling rig 102 drives the drill rod 104 to rotate, causing the drill rod 104 to drill into the coal seam. The connecting rod 103 is used to connect the drill rod 104 to the drilling rig 102, and the drilling rig 102 drives the drill rod 104 to operate through the connecting rod 103.

[0023] The guide ring 108 is fixedly connected to the connecting rod 103 and sleeved on the outer wall of the connecting rod 103. The connecting rod 103 has a groove 112, and the mounting base 107 is disposed in the groove 112. The two ends of the telescopic rod are fixedly connected to the connecting rod 103 and the mounting base 107, respectively. The two ends of the return spring 105 are fixedly connected to the connecting rod 103 and the mounting base 107, respectively, and sleeved on the outer wall of the telescopic rod. The drill bit 106 is fixedly connected to the mounting base 107 and located on the outer wall of the mounting base 107. When drilling in a coal mine, the drilling rig 102 is controlled to operate on the control console 101, and the drilling rig 102 drives the drill rod 104 to rotate. The drill rod 104 is moved to drill into the coal seam. When the drill rod 104 is buried or jammed, the drill rod 104 continues to advance. The drill bit 106 on the mounting base 107 will come into contact with the rocks. Since the rocks are mostly irregular in shape, when the drill bit 106 comes into contact with the rocks, the return spring 105 and the telescopic rod will extend and retract within the groove 112, so that the drill bit 106 comes into contact with the outer wall of the rocks, which can better break the rocks. The broken rocks will leave along the guide ring 108, avoiding the collapse of the coal seam that would prevent the drill rod 104 from continuing to operate. This can quickly solve the situation of the drill rod 104 being buried or jammed, ensuring the normal operation of the work.

[0024] Secondly, the connecting rod 103 also has a limiting groove 113. Two limiting blocks 109 are symmetrically arranged on the outer side wall of the mounting base 107, and both limiting blocks 109 are slidably connected to the connecting rod 103 and are respectively located in the limiting groove 113. When the drill bit 106 contacts the stone, the mounting base 107 will be squeezed. The mounting base 107 squeezes the telescopic rod and the return spring 105 in the groove 112. At the same time, the limiting blocks 109 on both sides of the mounting base 107 will slide in the limiting groove 113, which improves the stability of the movement of the mounting base 107, thereby improving the stability of the drill bit 106.

[0025] Meanwhile, the outer cylinder 111 is fixedly connected to the connecting rod 103 and located in the groove 112. One end of the inner rod 110 is slidably connected to the outer cylinder 111, and the other end of the inner rod 110 is fixedly connected to the mounting base 107. When the mounting base 107 is compressed, it compresses the return spring 105. At the same time, the mounting base 107 pushes the inner rod 110, and the inner rod 110 slides and extends within the outer cylinder 111, improving the stability of the movement of the mounting base 107.

[0026] When drilling in a coal mine, the drilling rig 102 is controlled from the control console 101. The drilling rig 102 drives the drill rod 104 to rotate, causing the drill rod 104 to drill into the coal seam. When the drill rod 104 is buried or jammed, the drill rod 104 continues to be advanced. The drill bit 106 on the mounting base 107 will come into contact with rocks. Since the rocks are mostly irregular in shape, the mounting base 107 will be compressed when the drill bit 106 comes into contact with the rocks. The mounting base 107 is pressed by the return spring 105 within the groove 112, and the inner rod 110 slides and extends within the outer cylinder 111, causing the drill bit 106 to contact the outer wall of the rock, thus enabling better crushing of the rock. The crushed rock will leave along the guide ring 108, preventing the coal seam from collapsing and causing the drill rod 104 to stop operating. This quickly resolves the situation where the drill rod 104 is buried or jammed, ensuring normal operation.

[0027] The second embodiment is as follows:

[0028] Based on the first embodiment, please refer to Figure 4 and Figure 5 ,in Figure 4 This is a schematic diagram of the overall structure of the second embodiment. Figure 5 This is a cross-sectional view of the overall internal structure of the second embodiment. The present invention provides a rapid handling device for stuck drill pipe 104 and buried drill accidents in coal mines, which also includes a flushing assembly. The flushing assembly includes a water tank 201, a high-pressure water pump 202, a connecting pipe 203, multiple nozzles 204, and an observation window 205.

[0029] In this specific embodiment, the flushing assembly is mounted on the control console 101, which can further improve the efficiency of handling stuck drill bits and buried drill bits.

[0030] The connecting rod 103 has a water collection chamber 206 and multiple water supply pipes 207. The water tank 201 and the high-pressure water pump 202 are respectively mounted on the control console 101. The high-pressure water pump 202 is connected to one end of the connecting pipe 203, and the other end of the connecting pipe 203 is connected to the water collection chamber 206. Multiple nozzles 204 are fixedly connected to the connecting rod 103 and are respectively connected to the corresponding water supply pipes 207. This is useful for handling drill jams and drill bit burial accidents. The drill bit 106 breaks the rocks, and at the same time, the high-pressure water pump 202 is activated. The high-pressure water pump 202 transports water from the water tank 201 to the water collection chamber 206 of the connecting rod 103 through the connecting pipe 203, and then transports the water to the nozzle 204 through the water supply pipeline 207. Finally, the nozzle 204 washes the surrounding area. In conjunction with the drill bit 106 breaking the rocks, it can achieve rapid rock breaking and further improve the efficiency of dealing with stuck drill bits and buried drill bits.

[0031] Secondly, the observation window 205 is fixedly connected to the water tank 201 and is located on the outer wall of the water tank 201. The remaining water volume of the water tank 201 can be viewed through the observation window 205.

[0032] When dealing with stuck or buried drill bits, the drill bit 106 breaks up the rocks, and the high-pressure water pump 202 is activated. The high-pressure water pump 202 transports water from the water tank 201 to the water collection chamber 206 of the connecting rod 103 through the connecting pipe 203, and then transports the water to the nozzle 204 through the water supply pipeline 207. The remaining water level in the water tank 201 can be viewed through the observation window 205. Finally, the surrounding area is flushed through the nozzle 204. In conjunction with the drill bit 106 breaking up rocks, rapid rock breaking is achieved, which can further improve the efficiency of dealing with stuck or buried drill bits.

[0033] The third embodiment is as follows:

[0034] Based on the second embodiment, please refer to Figure 6 ,in Figure 6 This is a schematic diagram of the overall structure of the third embodiment. The present invention provides a rapid handling device for stuck drill rod 104 and buried drill accidents in coal mines, which also includes an adjustment component. The adjustment component includes multiple support plates 301, a fixing plate 302, multiple hydraulic cylinders 303, and multiple rubber pads 304.

[0035] In this specific embodiment, the adjustment component is located below the control console 101. The height of the control console 101 and the height of the drill rod 104 can be adjusted by the adjustment component, which facilitates drilling in the coal mine.

[0036] The fixed plate 302 is fixedly connected to the control console 101 and located below the control console 101. Multiple hydraulic cylinders 303 are symmetrically arranged below the fixed plate 302, and the output end of each hydraulic cylinder 303 is fixedly connected to the fixed plate 302. Multiple support plates 301 are fixedly connected to the corresponding hydraulic cylinders 303 and located below each hydraulic cylinder 303. When adjusting the height of the drill rod 104, the hydraulic cylinders 303 are activated, and the hydraulic cylinders 303 push the fixed plate 302 upward, thereby pushing the workbench upward. The support plates 301 contact the ground, and the support plates 301 and the hydraulic cylinders 303 support the workbench, making it easier to adjust the height of the drill rod 104 for drilling in the coal mine.

[0037] Secondly, multiple rubber pads 304 are fixedly connected to the corresponding support plates 301 and are located on the outer wall of the support plates 301. The rubber pads 304 can improve the friction between the support plates 301 and the ground, thereby improving the stability of the control console 101.

[0038] When adjusting the height of the drill rod 104, the hydraulic cylinder 303 is activated, which pushes the fixed plate 302 upward, thereby pushing the worktable upward. The support plate 301 contacts the ground, and the support plate 301 and the hydraulic cylinder 303 support the worktable, making it easier to adjust the height of the drill rod 104 for drilling in the coal mine. The rubber pad 304 increases the friction between the support plate 301 and the ground, improving the stability of the control console 101.

[0039] The above description discloses only one preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
