Description

Technical Field

[0001] The invention relates to the technical field of in-situ solidification equipment, in particular to an improved in-situ solidification deep-layer telescopic drill rod device. Background Art

[0002] In-situ solidification (ISS) is a highly effective engineering technology that injects curing agents such as cement and chemicals into the original location of a target medium, such as soil, silt, groundwater, or pipelines. Combined with mechanical mixing and high-pressure spraying, this technology promotes a physical and chemical reaction between the medium and the curing agent, ultimately forming a solidified body with a specific strength and stability. This is used to achieve engineering goals such as foundation reinforcement, pollution control, and pipeline repair.

[0003] In the in-situ curing process, the telescopic drill rod, as a key executive component, assumes the core functions of transporting the curing agent and stirring the medium. However, the complex underground environment poses a severe challenge to the durability of the drill rod: particles such as mud, sand, and rock continuously generate friction and wear during drilling operations, resulting in material loss on the drill rod surface. At the same time, if the curing material is not promptly cleaned after adhesion, it will gradually solidify into a hard scale layer, increasing the friction coefficient between the drill rod and the surrounding medium, resulting in a significant increase in the equipment's operating resistance. This dual wear mechanism not only shortens the service life of the drill rod, but also leads to problems such as reduced curing agent delivery efficiency and insufficient mixing uniformity, directly affecting the construction quality and efficiency of the in-situ curing project. Summary of the Invention

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Example 1: Figures 1-8 As shown in the figure, an improved device for in-situ curing deep telescopic drill rod is included, including a moving platform 1, which is convenient for moving the entire device to the work site. A mechanical arm 2 is installed on the moving platform 1, and the mechanical arm 2 can achieve precise and flexible movements, quickly respond to work requirements, and reduce energy consumption. A connecting seat 3 is installed at the end of the mechanical arm 2 away from the moving platform 1, and also includes: a first motor 8 installed at the bottom of the connecting seat 3, and the output end of the first motor 8 is installed with a telescopic rod 15 through a coupling, and a drill rod 16 is installed at the bottom of the telescopic rod 15. A reinforcing component 4 is installed at the bottom of the connecting seat 3, and the reinforcing component 4 is used to enhance the stability of the drill rod 16; and a scraping component 5 installed on the reinforcing component 4, and the scraping component 5 is used to scrape the drill rod 16; and a cleaning component 6 installed on the reinforcing component 4, and the cleaning component 6 is used to cooperate with the scraping component 5 to clean the drill rod 16; and an anti-sticking component 7 installed on the reinforcing component 4, and the anti-sticking component 7 is used to prevent the curing material from sticking to the surface of the drill rod 16.

[0020] Furthermore, the reinforcing component 4 includes a driving wheel 9 symmetrically fixedly mounted on the output end of the first motor 8. A belt 10 is provided on the outside of the two driving wheels 9, and a driven wheel 11 is provided inside the two belts 10. The driving wheel 9 and the driven wheel 11 are made of wear-resistant nylon, which has good wear resistance, self-lubrication and a low friction coefficient. It can reduce wear and extend the service life during the transmission of the belt 10. The inside of the two driven wheels 11 is fixedly connected with a rotating rod 12. The two rotating rods 12 are rotatably connected to the connecting seat 3. The rotating rod 12 is made of stainless steel and has excellent corrosion resistance and strength. It can ensure stable rotation even when operating in a humid and corrosive environment.

[0021] For further information, see Figure 3 The two rotating rods 12 are rotatably connected to the bracket 13 at one end away from the connecting seat 3. The telescopic legs 14 are symmetrically installed at the bottom of the bracket 13. The telescopic legs 14 are located on the ground and can quickly adjust the height according to the ground conditions, which can enhance the stability of the drill rod 16.

[0022] For further information, please refer to Figure 4 The scraping component 5 includes a cylinder 17 fixedly mounted on the bottom of the connecting base 3. The cylinder 17 is fixedly connected to the connecting base 3 via a flange, making installation and removal easy. A guide rod 18 is fixedly connected to the output end of the cylinder 17. A slip ring 19 is installed on the outside of the guide rod 18. A slip ring 20 is installed below the slip ring 19. Both slip rings 19 and 20 are fixedly connected to the guide rod 18. Sliding blocks 25 are fixedly installed inside the slip rings 19 and 20. The sliding blocks 25 are slidably connected to the rotating rod 12. The guide rod 18 is pushed by the cylinder 17, which drives the slip rings 19 and 20 to move, thereby completely scraping the solidified material on the surface of the drill rod 16, thereby keeping the drill rod 16 clean and reducing the chance of wear of the drill rod 16.

[0023] In addition, it should be noted that a connecting sleeve 21 is installed in the slip ring 20, and telescopic springs 22 are evenly installed inside the connecting sleeve 21. The elastic coefficient of the telescopic spring 22 has been accurately calculated, which can enable the scraper 23 to always fit the surface of the drill rod 16 with appropriate pressure. The telescopic spring 22 can make the scraper 23 adaptively fit the surface of the drill rod 16. The outside of multiple telescopic springs 22 are fixedly connected to the scraper 23. The scraper 23 is made of special wear-resistant rubber material and has good elasticity and wear resistance. Scraper blocks 24 are installed on multiple scrapers 23. The scraper blocks 24 correspond to the drill rod 16. The scraper blocks 24 can correspond to the rotating blades on the surface of the drill rod 16, so that the scraping is cleaner.

[0024] Example 2: Figure 3-Figure 8As shown, this is a further description of Example 1. In this embodiment, the cleaning component 6 includes a water tank 26 installed on the mobile platform 1. The water tank 26 is made of food-grade stainless steel, which is corrosion-resistant and not easy to rust, ensuring the cleanliness of the stored water. A water pump 27 is installed on one side of the water tank 26. The input end of the water pump 27 is fixedly connected to the water tank 26, and the output end of the water pump 27 is fixedly connected to a hose 28. The hose 28 is a high-pressure rubber hose that can withstand high water pressure and has good flexibility and is easy to bend and install. The hose 28 passes through the connecting seat 3 and is fixedly connected to an annular tube 29. Nozzles 30 are evenly installed on the bottom of the annular tube 29. The annular tube 29 and the nozzle 30 are made of stainless steel, which is resistant to water corrosion and ensures that the cleaning water flows smoothly. The annular tube 29 is fixedly connected to the slip ring 19 through the sliding block 25.

[0025] Specifically, a booster pump 31 is installed at the bottom of the connecting seat 3. Both the water pump 27 and the booster pump 31 adopt frequency conversion control, and the water supply pressure and flow rate can be adjusted according to actual cleaning needs. One end of the booster pump 31 is fixedly connected to the hose 28, and the output end of the booster pump 31 is fixedly connected to the connecting pipe 32. The end of the connecting pipe 32 away from the booster pump 31 is fixedly connected to the annular pipe 29 and communicates with it. A control valve 33 is installed on the hose 28 and the connecting pipe 32. The thick solidified material can be flushed away through the booster pump 31 to prevent it from staying on the surface of the drill rod 16.

[0026] For further information, see Figure 4-Figure 7 The anti-sticking component 7 includes a protective cylinder 34 fixedly mounted on the bottom of the slip ring 19. The protective cylinder 34 is waterproof and dustproof to protect the internal electrical equipment. A second motor 35 is installed inside the protective cylinder 34. The output end of the second motor 35 is fixedly connected to the rotating shaft 36 through a coupling. The outside of the rotating shaft 36 is fixedly connected to a first bevel gear 37. The outside of the first bevel gear 37 is meshed with a second bevel gear 38. The second bevel gear 38 coaxially passes through the protective cylinder 34 and is fixedly connected to a rotating cylinder 39. A rubber head 40 is symmetrically mounted on the outside of the rotating cylinder 39. The rotating cylinder 39 is made of stainless steel. The rubber head 40 is made of high-elastic rubber material with good elasticity and wear resistance. It can effectively impact the moving block 43 to cause the drill rod 16 to vibrate. At the same time, due to its elasticity, it will not hinder the movement of the slip ring 19 and the slip ring 20. The end of the rotating shaft 36 away from the second motor 35 is rotatably connected to the slip ring 20. The drill rod 16 can be vibrated through the anti-sticking component 7 to separate the surface fine sand from the drill rod 16.

[0027] See also Figure 8A fixed cylinder 41 is fixedly installed on the outside of the telescopic rod 15, and a return spring 42 is fixedly connected to the inside of the fixed cylinder 41. A moving block 43 is installed at the bottom of the return spring 42, and the moving block 43 is slidably connected to the fixed cylinder 41. When the second motor 35 is started, the first bevel gear 37 and the second bevel gear 38 cooperate with each other to facilitate the rotation of the rubber head 40. Since the rubber head 40 is tilted, it can hit the moving block 43 during rotation, causing it to move inside the fixed cylinder 41, thereby driving the drill rod 16 to vibrate, thereby causing the surface solidified material to fall off, thereby protecting the drill rod 16.

[0028] To summarize, when using this device, first, after the device is activated, the mobile platform 1 moves to the working position under the control of the operator. The robotic arm 2 adjusts the position and angle of the connecting base 3 to align the drill rod 16 with the working point. The first motor 8 is activated, driving the rotating rod 12 via the driving pulley 9, belt 10, and driven pulley 11, thereby rotating the bracket 13 and telescopic legs 14, thereby enhancing the stability of the drill rod 16. Subsequently, the drill rod 16 is driven downward by the telescopic rod 15 to perform the in-situ curing operation. Next, when the drill rod 16 completes a lift, the cylinder 17 activates, pushing the guide rod 18 and driving the slip ring 19 and slip ring 20 downward. Because the sliding block 25 is slidably connected to the rotating rod 12, the slip ring 19 and slip ring 20 rotate with the rotation of the rotating rod 12, causing the scraper 23 and scraper block 24 to rotate around the surface of the drill rod 16, completely scraping away the solidified material on the surface of the drill rod 16. The action of the telescopic spring 22 allows the scraper 23 to adaptively conform to the surface of the drill rod 16, ensuring effective scraping. Once scraping is complete, the water pump 27 is activated to pump water from the water tank 26 and deliver it to the annular pipe 29 through the hose 28. Simultaneously, the booster pump 31 is activated as needed to boost the water flow, allowing the water to be sprayed from the nozzle 30 onto the surface of the drill pipe 16 at a suitable pressure and angle, flushing away the solidified material remaining after scraping. Finally, during the cleaning process or during breaks, the second motor 35 is activated, driving the first bevel gear 37 via the rotating shaft 36. The first bevel gear 37 meshes with the second bevel gear 38, driving the rotating drum 39 to rotate. Due to the inclined design of the rubber head 40, as the rotating drum 39 rotates, it continuously strikes the shifting block 43, causing it to move up and down within the fixed cylinder 41, thereby vibrating the drill rod 16. This vibration dislodges fine sand and residual solidified material from the surface of the drill rod 16, effectively preventing solidified material from adhering to the surface and protecting the drill rod 16.
