Description

Technical Field

[0001] This invention relates to the field of pipeline unblocking equipment technology, specifically a mine-use detachable high-pressure water spiral guide mine filling pipeline unblocking device. Background Technology

[0002] Pipeline blockage is a frequent occurrence in mine backfilling operations, seriously affecting the continuity of backfilling and operational safety. Currently used unblocking methods have significant shortcomings: manual dismantling by hammering is labor-intensive, cumbersome, and carries the risk of injury from slurry spray; high-pressure water flushing only works on the surface of the blockage and is extremely ineffective against dense, solidified slurry inside; simple mechanical unblocking devices are mostly single steel pipe structures, which directly contact the inner wall of the pipe during pushing, resulting in high frictional resistance and a lack of effective breaking and guiding structures, leading to low unblocking efficiency.

[0003] Although existing improvement solutions include setting spiral blades or cones at the front end of the steel pipe, the following problems still exist: the devices are mostly of fixed length, making it difficult to adjust flexibly according to the depth of blockage; the rotary drive relies on manual labor or an external motor, making downhole operation laborious and unsuitable; high-pressure water can only be sprayed out in one direction, and cannot erode the interior from multiple angles; after clearing the blockage, the pipe wall is prone to local collapse, exacerbating the risk of subsequent blockage. Summary of the Invention

Each striking component includes a mounting seat that is slidably installed on the middle steel pipe, and a roller is rotatably installed on the mounting seat. After the spiral guide vane is inserted into the mine filling pipe, the driving mechanism drives the spiral guide vane to rotate and drives several rollers to strike the pipe wall to clear the blockage.

[0006] As an optional solution of the detachable high-pressure water spiral guide mine filling pipeline unblocking device of the present invention, the unblocking mechanism further includes a plurality of first rotating rods, which are rotatably mounted on a plurality of mounting bases.

[0008] As an optional solution of the detachable high-pressure water spiral guide mine filling pipeline unblocking device of the present invention, wherein: two pulleys are fixedly installed on both the roller and the first rotating rod, and the two pulleys are connected by a transmission belt; As the rollers move in a circular motion along the middle steel pipe, they roll along the wavy guide groove via the guide wheel, causing the rollers to rotate while reciprocating in a linear motion based on the radius of the middle steel pipe.

[0009] As an optional embodiment of the detachable high-pressure water spiral guide mine filling pipeline unblocking device of the present invention, wherein: a second rotating rod is rotatably installed inside the first end steel pipe, a gear is fixedly installed on the second rotating rod, and a gear ring is fixedly installed inside the middle end steel pipe, the gear ring meshing with the gear.

[0010] As an optional solution of the detachable high-pressure water spiral guide mine filling pipeline unblocking device of the present invention, the driving mechanism includes a water tank fixedly installed in the first end steel pipe, and the high-pressure water injection pipe and the second rotating rod are both rotatably installed on the water tank.

[0011] As an optional solution of the detachable high-pressure water spiral guide mine filling pipeline unblocking device of the present invention, wherein: an annular pipe is fixedly installed inside the water tank, one end of the annular pipe is connected to the inner cavity of the water tank, and the other end of the annular pipe extends to the outside of the water tank for connection to a high-pressure water source.

[0012] As an optional embodiment of the detachable high-pressure water spiral guide mine filling pipeline unblocking device of the present invention, wherein: a rotating ring is rotatably installed on the annular pipe, and the rotating ring is driven to rotate by the annular water flow formed inside the annular pipe, and the second rotating rod is fixedly connected to the rotating ring.

[0013] As an optional solution of the detachable high-pressure water spiral guide mine filling pipeline unblocking device of the present invention, wherein: the first end steel pipe and the middle end steel pipe are connected by a wear-resistant rubber bearing, and a sealed waterproof bearing is installed on the tail end steel pipe.

[0014] As an optional solution of the detachable high-pressure water spiral guide mine filling pipeline unblocking device of the present invention, a handle is fixedly installed on the first end steel pipe.

[0015] The present invention has the following beneficial effects: 1. This mine-use detachable high-pressure water spiral guide mine filling pipeline unblocking device adopts a three-section detachable structure consisting of a front steel pipe, a middle steel pipe, and a tail steel pipe. The middle steel pipe is modularly designed, and multiple sections can be flexibly added according to the actual blockage depth of the mine filling pipeline. They are quickly assembled by threaded connection, without the need to replace the entire device. It is convenient for underground transport and transportation, and can adapt to the unblocking needs of pipelines of different lengths and diameters, effectively solving the problems of inconvenient disassembly and assembly and poor adaptability of existing devices.

[0016] 2. This detachable high-pressure water spiral guide mine filling pipeline unblocking device has a water tank, annular pipe and rotating ring installed in the steel pipe at the first end. It uses the existing high-pressure water source in the mine to drive the rotating ring to rotate, and then drives the middle steel pipe and spiral guide blades to rotate synchronously through the second rotating rod, gear and gear ring. No external motor or manual force is required to rotate. The operator only needs to hold the handle and push slowly, which greatly reduces the labor intensity of underground operations and avoids the safety hazards of electrical equipment in flammable and explosive environments.

[0017] 3. This detachable high-pressure water spiral guide mine filling pipeline unblocking device features a striking assembly on the middle steel pipe, consisting of a mounting base, rollers, a first rotating rod, a guide wheel, and a disc with a wavy guide groove. When the middle steel pipe rotates, the guide wheel rolls along the wavy guide groove, forcing the mounting base and rollers to reciprocate linearly in the radial direction, thereby continuously striking the pipe wall. Simultaneously, the rotation of the first rotating rod is synchronously transmitted to the rollers through pulleys and a transmission belt, causing the rollers to rotate during the striking process, which can more effectively scrape and crush the solidified slurry on the pipe wall.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1, please refer to Figures 1-6 A detachable high-pressure water spiral guide mine filling pipeline unblocking device includes a head steel pipe 1, a middle steel pipe 2 rotatably installed on the head steel pipe 1, and a tail steel pipe 3 threadedly installed on the middle steel pipe 2.

[0027] A spiral guide vane 4 is fixedly installed on the tail end steel pipe 3. A tungsten steel cone head 5 is fixedly installed on the head of the spiral guide vane 4. Several guide grooves 6 are opened on the spiral guide vane 4. The several guide grooves 6 are all connected to the inner cavity of the spiral guide vane 4. A high-pressure water injection pipe 7 is fixedly installed on the spiral guide vane 4.

[0028] The middle steel pipe 2 is also equipped with a blockage clearing mechanism and a driving mechanism. The blockage clearing mechanism includes several striking components arranged in a circle on the middle steel pipe 2. The striking components include a mounting seat 8 that is slidably installed on the middle steel pipe 2, and a roller 9 is rotatably installed on the mounting seat 8.

[0029] After the spiral guide vane 4 is inserted into the mine filling pipe, the spiral guide vane 4 is driven to rotate by the drive mechanism and several rollers 9 are driven to knock on the pipe wall to clear the blockage.

[0030] In this embodiment: the device adopts a three-section detachable structure, including a front steel pipe 1, a middle steel pipe 2, and a rear steel pipe 3. Among them, the front steel pipe 1 serves as the operating end, and a handle 24 is fixedly installed at its rear end for the operator to hold and push.

[0031] The intermediate steel pipe 2 and the tail steel pipe 3 are connected by threads, allowing for flexible installation of multiple intermediate steel pipe sections 2 according to the actual depth of the blocked pipe. Each intermediate steel pipe section 2 has standard external threads machined at both ends, enabling quick assembly and disassembly via threaded connectors. The intermediate steel pipe 2 adopts a modular design, allowing operators to select the appropriate number of intermediate steel pipe sections 2 for splicing based on the measured blockage depth downhole, thus adapting to filling pipes of different lengths. Sealing gaskets are installed at all threaded connections to ensure no leakage of high-pressure water during transmission.

[0032] A spiral guide vane 4 is fixedly installed at the end of the tail-end steel pipe 3. The spiral guide vane 4 is a steel spiral structure with a hollow interior, communicating with the inner cavity of the tail-end steel pipe 3. A tungsten steel cone 5 is fixedly installed at the head of the spiral guide vane 4, i.e., the end away from the tail-end steel pipe 3. The tungsten steel cone 5 has high hardness and wear resistance, facilitating drilling into dense and solidified filling slurry blockages. Several guide grooves 6 are formed on the spiral surface of the spiral guide vane 4, and these guide grooves 6 are all communicating with the inner cavity of the spiral guide vane 4. A high-pressure water injection pipe 7 is fixedly installed at the root of the spiral guide vane 4, and the other end of the high-pressure water injection pipe 7 extends to the vicinity of the head-end steel pipe 1 for connecting to an external high-pressure water source.

[0033] When unblocking is required, the tungsten carbide cone 5 and the spiral guide vane 4 are inserted into the mine filling pipe. Then, an external drive mechanism rotates the middle steel pipe 2 and the tail steel pipe 3, which in turn drives the spiral guide vane 4 to rotate at high speed. Simultaneously, high-pressure water is injected into the inner cavity of the spiral guide vane 4 through the high-pressure water injection pipe 7, and then sprayed out at high speed from the guide channel 6, hydraulically eroding the blockage slurry. The combined effect of the rotating mechanical crushing of the spiral guide vane 4 and the multi-angle erosion of the high-pressure water rapidly disintegrates the blockage.

[0034] Example 2, please refer to Figures 1-6 The unblocking mechanism also includes several first rotating rods 10, which are rotatably mounted on several mounting bases 8.

[0035] Guide wheels 11 are fixedly installed on several first rotating rods 10, and a disc 12 is fixedly installed inside the first end steel pipe 1. A guide groove 13 is opened on the disc 12, and the guide wheel 11 is slidably connected in the guide groove 13. The guide groove 13 is wavy.

[0036] Two pulleys 14 are fixedly installed on both the roller 9 and the first rotating rod 10, and the two pulleys 14 are connected by a transmission belt 15.

[0037] As several rollers 9 move in a circular motion along the middle steel pipe 2, they roll along the wavy guide groove 13 via the guide wheel 11, causing the rollers 9 to rotate while making reciprocating linear motion based on the radial direction of the middle steel pipe 2.

[0038] In this embodiment, a blockage-clearing mechanism is also provided on the middle steel pipe 2. This blockage-clearing mechanism includes several striking components arranged circumferentially on the middle steel pipe 2. Each striking component includes a mounting base 8 and a roller 9. The mounting base 8 is slidably mounted on the middle steel pipe 2 and can reciprocate along the radial direction of the middle steel pipe 2. The roller 9 is rotatably mounted on the mounting base 8, with the wheel surface of the roller 9 facing outwards for contacting the inner wall of the mine filling pipeline.

[0039] To achieve the radial reciprocating motion of the mounting base 8, the unblocking mechanism also includes several first rotating rods 10. Each first rotating rod 10 is rotatably mounted on a mounting base 8, and the axis of the first rotating rod 10 is parallel to the axis of the middle steel pipe 2. A guide wheel 11 is fixedly mounted on each first rotating rod 10. A disc 12 is fixedly mounted inside the first steel pipe 1. The disc 12 has an annular disc structure, and a guide groove 13 is opened on the side facing the guide wheel 11. The guide groove 13 is wavy, that is, it presents an undulating annular track along the circumference. The guide wheel 11 is slidably connected in the guide groove 13 and can roll along the guide groove 13.

[0040] When the drive mechanism rotates the middle steel pipe 2, the middle steel pipe 2 drives all the mounting seats 8 and the first rotating rod 10 to move in a circular motion. At this time, the guide wheel 11 is forced to roll along the wavy guide groove 13. Due to the radial height variation of the guide groove 13, the guide wheel 11 drives the first rotating rod 10 and the mounting seats 8 to reciprocate linearly along the radial direction of the middle steel pipe 2 during the rolling process. When the mounting seats 8 move outward, the roller 9 will impact and squeeze the inner wall of the pipe. When it moves inward, it will disengage. This cycle repeats, realizing the continuous impact of the roller 9 on the pipe wall.

[0041] Furthermore, to further enhance the cleaning effect on stubborn dirt on the pipe wall, this embodiment also includes two pulleys 14 fixedly installed on both the roller 9 and the first rotating rod 10. The pulleys 14 on the same side are connected by a transmission belt 15. When the guide wheel 11 rolls along the guide groove 13, the guide wheel 11 itself will also rotate, thereby driving the first rotating rod 10 to rotate. The first rotating rod 10 transmits the rotational motion to the roller 9 through the pulleys 14 and the transmission belt 15, so that while the roller 9 is making radial reciprocating striking motion, its wheel surface is also rotating. The rotating roller 9 can more effectively scrape and crush the solidified slurry on the pipe wall.

[0042] Example 3, please refer to Figures 1-6A second rotating rod 16 is rotatably installed inside the first steel pipe 1, and a gear 17 is fixedly installed on the second rotating rod 16. A gear ring 18 is fixedly installed inside the middle steel pipe 2, and the gear ring 18 meshes with the gear 17.

[0043] The drive mechanism includes a water tank 19 fixedly installed inside the steel pipe 1 at the head end, and a high-pressure water injection pipe 7 and a second rotating rod 16 rotatably installed on the water tank 19.

[0044] In this embodiment: A second rotating rod 16 is rotatably mounted inside the first-end steel pipe 1. The axis of the second rotating rod 16 coincides with the axis of the first-end steel pipe 1, and a gear 17 is fixedly mounted on its front end near the middle-end steel pipe 2. A gear ring 18 is fixedly mounted on the inner wall of the middle-end steel pipe 2, and the gear ring 18 meshes with the gear 17. The diameter of the gear 17 is smaller than the diameter of the gear ring 18, forming a speed reduction transmission.

[0045] The rotation of the second rotating rod 16 will drive the gear 17 to rotate, and the gear 17 will then drive the gear ring 18 and the middle steel pipe 2 fixed thereto to rotate. Due to the tooth ratio between the gear 17 and the gear ring 18, the rotational speed of the middle steel pipe 2 is lower than that of the second rotating rod 16, thereby achieving torque amplification and ensuring that the spiral guide vane 4 and the roller 9 obtain sufficient crushing force.

[0046] The tail end of the second rotating rod 16, away from the middle steel pipe 2, is connected to the power source of the drive mechanism. In this embodiment, the drive mechanism includes a water tank 19 fixedly installed inside the first-end steel pipe 1. Both the high-pressure water injection pipe 7 and the second rotating rod 16 are rotatably mounted on the water tank 19, and both are equipped with sealed bearings and mechanical seal assemblies at their connections to the water tank 19 to ensure that high-pressure water does not leak from the rotation gap. The water tank 19 is used to temporarily store and guide the high-pressure water flow, and also serves as a support structure for the second rotating rod 16.

[0047] It should be noted that all rotating connections between the first end steel pipe 1, the middle end steel pipe 2, and the last end steel pipe 3 are equipped with sealing structures. Specifically, the wear-resistant rubber bearing 22 between the first end steel pipe 1 and the middle end steel pipe 2 has both wear resistance and sealing functions. The sealed waterproof bearing 23 on the last end steel pipe 3 adopts a double-lip seal structure. The high-pressure water injection pipe 7 and the water tank 19, as well as the second rotating rod 16 and the water tank 19, both use combined dynamic seals, such as rubber sealing rings combined with PTFE retaining rings. These sealing measures ensure that the device can operate stably for a long time in high-pressure water environments and downhole conditions filled with slurry, effectively preventing internal parts from rusting and jamming. This is also a pre-emptive solution to common sealing defects in this field.

[0048] Example 4, please refer to Figures 1-6 The driving mechanism includes a water tank 19 fixedly installed inside the steel pipe 1 at the head end, and a high-pressure water injection pipe 7 and a second rotating rod 16 are rotatably installed on the water tank 19.

[0049] A rotating ring 21 is rotatably mounted on the annular pipe 20. The rotating ring 21 is driven to rotate by the annular water flow formed inside the annular pipe 20. The second rotating rod 16 is fixedly connected to the rotating ring 21.

[0050] The first end steel pipe 1 and the middle end steel pipe 2 are connected by a wear-resistant rubber bearing 22, and a sealed waterproof bearing 23 is installed on the tail end steel pipe 3.

[0051] A handle 24 is fixedly installed on the first end of the steel pipe 1.

[0052] In this embodiment: An annular pipe 20 is fixedly installed inside the water tank 19. The annular pipe 20 is a closed pipe with an annular cavity, arranged in a circle around the axis of the second rotating rod 16. One end of the annular pipe 20 communicates with the inner cavity of the water tank 19, and the other end extends out of the water tank 19 for connection to a high-pressure water source in the well via a quick connector. The annular section of the annular pipe 20 has a smooth channel inside, and there are no other structures inside the annular section that obstruct water flow.

[0053] A rotating ring 21 is rotatably installed on the annular section of the annular pipe 20. The rotating ring 21 is circular and is fitted on the outside or inside of the annular pipe 20. In this embodiment, it is preferably fitted on the outside. The inner wall of the rotating ring 21 is provided with multiple blades or grooves so that when high-pressure water flows through the annular pipe 20, it can drive the rotating ring 21 to rotate around its axis.

[0054] The specific principle is as follows: When the high-pressure water source is connected to the annular pipe 20, the water flows in from the external interface, flows at high speed along the annular cavity of the annular pipe 20, and finally flows out from the end connected to the inner cavity of the water tank 19, enters the water tank 19, and continues to be transported forward to the high-pressure water injection pipe 7. When the high-pressure water flows through the annular section of the annular pipe 20, the flowing water impacts the blades on the rotating ring 21, driving the rotating ring 21 to rotate continuously. This hydraulic drive method does not require an external motor or power supply, directly utilizes the existing high-pressure water source underground, has a simple structure, is explosion-proof and safe, and is particularly suitable for underground mining environments.

[0055] The rotating ring 21 is fixedly connected to the second rotating rod 16. Specifically, the tail end of the second rotating rod 16 passes through the water tank 19 and is fixed to the center of the rotating ring 21 by a key connection or welding. Therefore, when the rotating ring 21 is driven to rotate by water flow, the second rotating rod 16 rotates synchronously, which in turn drives the middle steel pipe 2 and the tail steel pipe 3 to rotate via the gear 17 and the gear ring 18. The operator can control the rotation speed of the rotating ring 21 by adjusting the flow rate and pressure of the external high-pressure water source, thereby achieving stepless speed regulation to adapt to blockages of different degrees of solidification.

[0056] Furthermore, considering the stability of the hydraulic drive, a manual regulating valve can be installed on the inlet pipe of the annular pipe 20. Operators can adjust the water flow at any time according to the actual resistance during the unblocking process, ensuring the device operates at its optimal speed. Simultaneously, to ensure reliable sealing during long-term operation, a labyrinth seal with grease filling is used between the annular pipe 20 and the rotating ring 21, reducing frictional resistance and preventing high-pressure water leakage.

[0057] The first end steel pipe 1 and the middle end steel pipe 2 are rotatably connected by a wear-resistant rubber bearing 22, allowing the middle end steel pipe 2 and its subsequent components to rotate freely relative to the first end steel pipe 1. The wear-resistant rubber bearing 22 is made of high-strength wear-resistant rubber material, with its inner ring fixed to the first end steel pipe 1 and its outer ring fixed to the middle end steel pipe 2. It serves both as a bearing support and has good wear resistance and sealing properties, preventing external slurry from entering the rotation gap.

[0058] In addition, the sealed waterproof bearing 23 adopts a multi-layer sealing structure, which can effectively prevent high-pressure water and slurry from seeping into the bearing and causing jamming.

[0059] The workflow of the entire device is summarized as follows: First, assemble an appropriate number of intermediate steel pipes 2 according to the depth of the blockage. Insert the spiral guide vanes 4 into the pipes and press them against the blockage. Then, turn on the external high-pressure water source. One stream of high-pressure water enters the annular pipe 20, driving the rotating ring 21 to rotate, which in turn drives the spiral guide vanes 4 and rollers 9 to rotate through the transmission mechanism. Another stream enters the inner cavity of the spiral guide vanes 4 through the high-pressure injection pipe 7 and is sprayed out from the guide groove 6. The operator holds the handle 24 and slowly pushes the device forward. Under the control of the wave-shaped guide groove 13, the rollers 9 repeatedly strike and squeeze the pipe wall, and the spiral guide vanes 4 continuously break and erode the blockage. After the blockage is cleared, turn off the water source, rotate in the opposite direction to exit the device, and disassemble each section of steel pipe for cleaning and storage.

[0060] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0061] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
