Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of drilling rig water injection, specifically to a water injection device for a tracked drilling rig used in coal mines. Background Technology

[0002] In coal mining, tracked water exploration and drainage drilling rigs are key equipment for ensuring safe production in mines. They are mainly used to detect and drain water accumulated in coal seams to prevent water inrush accidents. The water injection device, as an important auxiliary system of the drilling rig, provides cooling water for the drilling process, reduces drill bit temperature and dust pollution, and ensures the normal operation of the drilling rig's cooler, directly affecting drilling efficiency and equipment lifespan.

[0003] Currently, the water injection devices of tracked water exploration and drainage drilling rigs used in coal mines have significant drawbacks, with unreasonable installation location and operation methods being prominent issues. These devices are typically installed in front of the water supply pipeline, far from the drilling rig's operating area, making it impossible for the drilling operator to directly control the water flow during operation. To adjust the water volume, a dedicated person must be assigned to monitor and operate the water injection device, which not only increases labor costs but also easily leads to delays in water flow adjustment due to untimely information transmission.

[0004] More importantly, when personnel operate in front of the pipeline, they face safety risks such as potential roof collapses and signs of water seepage in the drilling area, threatening the safety of the workers. Simultaneously, improper water flow regulation can lead to excessive load on the cooler, while insufficient water flow will fail to meet cooling requirements, both shortening the cooler's lifespan and even causing drill bit jamming or damage due to overheating, severely impacting drilling progress. Therefore, addressing the operational shortcomings of existing water injection devices and developing a more adaptable water injection device for tracked exploration and drainage drilling rigs in coal mines has become an urgent need to improve drilling safety and efficiency.

[0031] like Figures 1-3 As shown, it illustrates a water injection device for a tracked water exploration and drainage drilling rig in a coal mine according to an embodiment of the present disclosure, comprising:

[0032] A three-way pipe 1 and a main frame 2, wherein the three-way pipe 1 is mounted on the main frame 2;

[0033] Connecting component 3, which is disposed on the three-way pipe 1 and the main frame 2;

[0034] Water injection component 4, wherein the water injection component 4 is disposed at the lower end of the three-way pipe 1;

[0035] The connection component 3 includes a first solenoid valve 3-1, which is mounted on the main frame 2. A first sleeve 3-2 is inserted and connected to one end of the bottom of the main frame 2. A first stud 3-3 is threadedly connected to one end of the main frame 2. One end of the first stud 3-3 is supported on the side face of the first sleeve 3-2. A device connection pipe 3-4 is fitted inside the first sleeve 3-2. One end of the device connection pipe 3-4 is connected to one end of the first solenoid valve 3-1. A filter 3-5 is fitted inside the device connection pipe 3-4. The bottom of the main frame 2... The other end of the main frame is connected to a second bracket 3-6. A second stud 3-7 is inserted into the second bracket 3-6. One end of the second stud 3-7 is connected to the main frame 2 by a threaded connection. A connecting pipe 3-8 is fitted into one end of the second bracket 3-6. One end of the connecting pipe 3-8 is connected to the other end of the first solenoid valve 3-1. One end of the three-way pipe 1 is fitted into the other end of the bottom of the second bracket 3-6. One end of the connecting pipe 3-8 is inserted into one end of the three-way pipe 1. A sealing cap 3-9 is connected to one end of the three-way pipe 1 by a threaded connection.

[0036] In some examples, the connection component 3 achieves stable connection between the drilling rig's water supply and external water supply through dual-path access and sealing fixation. The first solenoid valve 3-1 on the main frame 2 is fixed with bolts and serves as the control core for water circuit switching. The first sleeve 3-2 at one end of the bottom of the main frame 2 is tubular and is horizontally inserted into the slot of the main frame 2, allowing for slight adjustment of its position in the horizontal direction. The first stud 3-3 at one end of the main frame 2 is screwed into the threaded hole of the main frame 2, with its end abutting against the side face of the first sleeve 3-2. Tightening it can fix the position of the first sleeve 3-2. The equipment connection pipe 3-4 inside the first sleeve 3-2 is clearance-fitted with the inner wall of the sleeve. One end is connected to one interface of the first solenoid valve 3-1 through a flange, and the other end is used to connect to the water supply pipeline of the drilling rig. The filter 3-5 inside the equipment connection pipe 3-4 is fixed with a retaining ring and can filter impurities in the water to prevent clogging of the pipeline. The second bracket 3-6 at the other end of the bottom of the main frame 2 is also inserted into the slot of the main frame 2. The second stud 3-7 is screwed into the main frame 2 by threads, and its end abuts against the second bracket 3-6 to fix its position. One end of the connecting pipe 3-8 in the second bracket 3-6 is connected to the other interface of the first solenoid valve 3-1, and the other end is inserted into one end of the tee pipe 1. The connection is sealed by a sealing ring. One end of the tee pipe 1 is fitted into the other end of the bottom of the second bracket 3-6 and is positioned by the second bracket 3-6. The sealing cap 3-9 at one end of the tee pipe 1 is tightened by threads to close the interface or connect to an external water supply pipeline.

[0037] During operation, the first stud 3-3 and the second stud 3-7 respectively fix the positions of the first bracket 3-2 and the second bracket 3-6, ensuring precise connection between the equipment connection pipe 3-4 and the connecting pipe 3-8. The filter 3-5 filters impurities in the water, protecting the solenoid valve and subsequent pipelines. The first solenoid valve 3-1 controls the on / off of the two water circuits, allowing switching between water supply to the drilling rig or external water supply as needed. The sealing cap 3-9 ensures a tight seal when no external water supply is connected. The insert structure of the first bracket 3-2 and the second bracket 3-6 facilitates pipeline installation and disassembly. The stud-contact fixing method allows for fine-tuning of the bracket position, ensuring smooth pipeline connection. The sealing ring and sealing cap 3-9 enhance the sealing of each connection point, preventing leakage. The addition of the filter 3-5 improves the cleanliness of the water circuit and extends the service life of the equipment. This component, through its dual-path access design and reliable fixed sealing structure, achieves flexible switching and stable connection between the drilling rig's water supply and external water supply.

[0038] like Figures 1-3 As shown in this embodiment, the water injection component 4 includes a second solenoid valve 4-1, which is connected to the lower end of the three-way pipe 1. The other end of the second solenoid valve 4-1 is connected to a water outlet pipe 4-2. A connecting sleeve 4-3 is provided at the lower end of the water outlet pipe 4-2. A spray pipe 4-4 is rotatably sealed and connected inside the connecting sleeve 4-3. A pressure cap 4-5 is fitted at the upper end of the spray pipe 4-4. The pressure cap 4-5 and the connecting sleeve 4-3 are fixedly connected by screws.

[0039] In some examples, the water injection assembly 4 achieves flexible adjustment of the water outlet direction through a rotatable structure and sealed fixation. The second solenoid valve 4-1 at the lower end of the three-way pipe 1 is connected via a flange and is used to control the on / off state of the water injection path. The outlet pipe 4-2 at the other end of the second solenoid valve 4-1 is connected via a thread. The connecting sleeve 4-3 at the lower end is integrally formed or welded to the outlet pipe 4-2, forming a tubular structure with an annular groove on its inner wall. The upper end of the spray pipe 4-4 is inserted into the connecting sleeve 4-3 and is rotatably connected to the connecting sleeve 4-3 via a bearing, allowing for 360-degree rotation. A sealing ring is provided at the connection point, embedded in the annular groove of the connecting sleeve 4-3 to prevent leakage. The cap 4-5 at the upper end of the spray pipe 4-4 is annular and fits onto the spray pipe 4-4. It is fixed to the top of the connecting sleeve 4-3 with screws, axially limiting the spray pipe 4-4 and preventing it from falling off. Different nozzles can be installed at the lower end of the spray pipe 4-4 as needed.

[0040] During operation, the second solenoid valve 4-1 controls the opening and closing of the water outlet pipe 4-2. When the water outlet direction needs to be adjusted, the spray pipe 4-4 is rotated, and its orientation can be easily changed under the action of the bearing to meet different water injection angle requirements. The sealing ring ensures the sealing of the connection during the rotation of the spray pipe 4-4, preventing water leakage from the gap. The fixed structure of the gland 4-5 and the connecting sleeve 4-3 ensures that the spray pipe 4-4 will not move axially during rotation, ensuring a stable connection. The bearing allows the spray pipe 4-4 to rotate flexibly, facilitating quick adjustment of the water outlet direction. The cooperation between the sealing ring and the gland 4-5 ensures both sealing and reliable positioning, preventing the spray pipe 4-4 from shifting under water pressure. The fixed connection between the water outlet pipe 4-2 and the connecting sleeve 4-3 enhances the stability of the overall structure and can withstand the water pressure impact during water injection. This component, through the rotatable spray pipe 4-4 structure, achieves flexible adjustment of the water outlet direction while ensuring the sealing and stability of the water injection process.

[0041] For example, such as Figure 2 As shown, the second solenoid valve 4-1 is provided with a plug 5, which is inserted into the main frame 2 and is fixedly connected to the main frame 2 by screws.

[0042] In some examples, the insert 5 on the second solenoid valve 4-1 is inserted into the main frame 2 and secured with screws, which enhances the installation stability of the second solenoid valve 4-1. The insertion and engagement of the insert 5 with the main frame 2 achieves precise positioning, preventing the second solenoid valve 4-1 from shifting due to vibration during equipment operation and ensuring the sealing of the connection with the tee pipe 1 and the outlet pipe 4-2. The screw fixing further reinforces the system, preventing loosening and allowing the second solenoid valve 4-1 to stably control the flow of water, ensuring the normal operation of the water injection assembly 4.

[0043] For example, such as Figure 1 As shown, the main frame 2 has several fixing holes 6 at both ends of its top.

[0044] In some examples, the fixing holes 6 at both ends of the top of the frame can be used to fix the entire device to the drilling rig. The fixing holes 6 are adapted to bolts and other connectors, and the fixing points can be adjusted according to the installation position of the drilling rig, enhancing the connection between the device and the drilling rig. When the crawler drilling rig moves or operates, it can prevent the device from shaking or shifting, ensuring the stable connection of each component of the connecting component 3 and the water injection component 4, and ensuring the smooth progress of the water injection operation.

[0045] In actual use: The device is installed in a suitable position on the drilling rig through the fixing hole 6 on the top of the main frame 2. The first stud 3-3 is rotated to fix the first sleeve 3-2, so that the equipment connecting pipe 3-4 is connected to the water supply pipeline of the drilling rig. The filter 3-5 filters impurities. The second stud 3-7 fixes the second sleeve 3-6. The connecting pipe 3-8 connects the first solenoid valve 3-1 and the three-way pipe 1. The sealing cap 3-9 seals the unused interface. When water is injected, the first solenoid valve 3-1 switches the water path, and the water flows into the water injection component 4 through the three-way pipe 1. The second solenoid valve 4-1 controls the opening and closing of the water outlet pipe 4-2. The spray pipe 4-4 can be rotated and adjusted in angle within the connecting sleeve 4-3. The pressure cap 4-5 ensures that it is sealed and does not fall off. The insert block 5 reinforces the connection between the second solenoid valve 4-1 and the main frame 2, realizing flexible operation and stable water injection throughout the process.
