[0002] As an important tool in the field of underground engineering and infrastructure construction, the long spiral drilling rig plays an indispensable role. However, during its working process, the drill rod is one of the core components, and its performance and durability are directly related to the efficiency and quality of the drilling rig's work.

[0003] Most of the current protection devices focus on protecting the drill rod during operation, such as using baffles to block flying rock fragments or pre-drilling holes through double drill rods. However, these devices ignore the protection of the drill rod when the long spiral drill rig is idle. When the drill rig is idle, environmental factors such as rain, bird droppings, and sunlight can easily cause rust, deformation, and cracking on the surface of the drill rod, thereby reducing the strength and rigidity of the drill rod and shortening its service life.

[0004] In order to deal with these problems, the current practice is usually that operators need to disassemble and store the drill pipe, or use temporary covers to protect the drill pipe. However, due to the long drill pipe, it often requires multiple people to cooperate to pull the cover, which is cumbersome, time-consuming and labor-intensive. Utility Model Content

[0026] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0027] As shown in the figure, the present embodiment provides a long spiral drilling rig protection device, comprising a bearing platform 1, a moving seat 2 is slidably provided at the top of the bearing platform 1, a long spiral drilling rig is installed on the moving seat 2, and the long spiral drilling rig comprises a motor body 3 and a drill rod 4 respectively installed on both sides of the moving seat 2, and a protective mechanism is fixed on the side of the top of the bearing platform 1 away from the moving seat 2; the bearing platform 1 can be transported to a designated working area by a drilling rig transport vehicle, and the inclination angle of the bearing platform 1 can be adjusted by adjusting the bracket to meet different drilling angle requirements, the propulsion mechanism drives the moving seat 2 to move the drill rod 4 along the track of the bearing platform 1, and the motor body 3 provides rotational power for the drill rod 4, thereby realizing the drilling work, and after the work is completed, the propulsion mechanism is operated again to reset the drill rod 4;

[0028] The protection mechanism includes a working box 5, a circular through slot 6 is provided in the center of the working box 5. When the drill rod 4 is working, the drill rod 4 can pass through the circular through slot 6 and go out of the other side of the working box 5. A bellows sleeve 7 is fixed on the side of the working box 5 close to the moving seat 2 and located outside the circular through slot 6. A magnetic ring 8 is fixed on the end of the bellows sleeve 7 away from the working box 5. A magnetic ring 9 adapted to the magnetic ring 8 is provided on the side of the moving seat 2 close to the bellows sleeve 7. When the drill rod 4 is not working and idle, the magnetic ring 8 can be magnetically connected with the magnetic ring 9 on the moving seat 2, so that the bellows sleeve 7 can be sleeved on the outside of the drill rod 4 to protect the drill rod 4, thereby effectively reducing the corrosion and damage to the drill rod 4 caused by impurities such as rainwater, bird droppings and dust, and providing comprehensive protection for the drill rod 4 when it is idle, thereby improving its overall durability and service life.

[0029] At the same time, considering that the drill rod 4 may rotate during operation, in order to ensure that there is no friction and damage between the bellows sleeve 7 and the drill rod 4, an inner protective shell 10 is provided inside the bellows sleeve 7, and one end of the inner protective shell 10 close to the working box 5 is fixed on the working box 5, and the end of the inner protective shell 10 away from the working box 5 can be magnetically connected to the magnetic ring 8. When the drill rod 4 is working, the magnetic ring 8 is magnetically connected to the inner protective shell 10, and the bellows sleeve 7 is located on the outside of the inner protective shell 10 at this time. The drill rod 4 can penetrate the inside of the inner protective shell 10 when working, thereby effectively avoiding direct contact between the bellows sleeve 7 and the drill rod 4, and avoiding damage to the bellows sleeve 7 when the drill rod 4 rotates.

[0030] In addition, in order to effectively solve the problem of the possible splashing of mud or gravel during the operation of the drill pipe 4, which may cause pollution or damage to the bellows sleeve 7, an outer protective shell 11 is provided on the outer side of the bellows sleeve 7, and one end of the outer protective shell 11 is fixed on the working box 5. When the drill pipe 4 is working, if there is splashing of mud or gravel, the outer protective shell 11 can provide an additional barrier for the bellows sleeve 7, which can prevent the contact of mud or gravel with the bellows sleeve 7 during the operation, thereby avoiding possible pollution and damage, and further improving the service life of the bellows sleeve 7.

[0031] In addition, in order to conveniently clean the large amount of impurities and attached mud accumulated on the outside of the drill rod 4 after the work is completed, the protection mechanism also includes a cleaning component; the cleaning component includes a drive motor 12 fixedly arranged inside the working box 5, and in order to stably install the drive motor 12, a mounting frame adapted to the drive motor 12 can be installed inside the working box 5, and the drive motor 12 is installed on the mounting frame by bolts, and a turntable 13 is fixed to the output end of the drive motor 12, and the turntable 13 is connected to the circular tube 14 through a belt 25, and the circular tube 14 is rotatably arranged on the circular tube 14. Inside the through groove 6, an annular water groove 15 is provided on the inner wall of the circular through groove 6, and two blocking rings 16 are provided on the outer wall of the circular tube 14. The two blocking rings 16 are respectively attached to the two sides of the inside of the annular water groove 15. A spray hole is provided on the outer wall of the circular tube 14, and the spray hole is located between the two blocking rings 16. The blocking ring 16 can be used to block the gap between the annular water groove 15 and the circular tube 14. When clean water is injected into the annular water groove 15, the blocking ring 16 can prevent the clean water from flowing out of the gap between the circular tube 14 and the annular water groove 15, thereby maintaining the water in the annular water groove 15.

[0032] The cleaning component also includes a water tank 18 fixed inside the working box 5, on which a water pump 19 is fixed. The input end of the water pump 19 is connected to the water tank 18, and the output end of the water pump 19 is fixed with a drain pipe 20. The water outlet end of the drain pipe 20 is located in the annular water tank 15 and between the two blocking rings 16.

[0033] When the work of the drill rod 4 is completed, it is reset by the propulsion mechanism. At this time, the drive motor 12 and the water pump 19 operate simultaneously, and then the water in the water tank 18 is discharged into the annular water tank 15 through the drain pipe 20. Through the injection holes set on the circular tube 14, the high-pressure cleaning water is guided toward the outside of the drill rod 4, and the impurities attached to the outside of the drill rod 4 are effectively washed away in a strong spraying manner. The operation of the drive motor 12 drives the circular tube 14 to start rotating through the belt 25. Due to the rotation of the circular tube 14, the injection holes can rotate on the outside of the drill rod 4, so that the outside of the drill rod 4 can be efficiently cleaned, which not only reduces the dead angles that may occur during cleaning, but also improves the cleaning effect and range.

[0034] In order to conveniently inject clean water into the water tank 18, a water injection pipe is provided on one side of the top of the water tank 18, and the water injection pipe runs through the interior of the working box 5, and a blocking block is provided on it. When cleaning, the blocking block can be removed to inject clean water into the water tank 18 through the water injection pipe. After the injection is completed, the water injection pipe is blocked by the blocking block to prevent the clean water from flowing out.

[0035] In order to conveniently start the water pump 19 and the drive motor 12 at the same time, a control host is also provided inside the working box 5. The drive motor 12 and the water pump 19 are electrically connected to the control host. Through the control host, the drive motor 12 and the water pump 19 can be comprehensively and accurately managed. The control host is an existing and mature technology and is widely used in the electronic control and industrial fields. It will not be described in detail in this embodiment.

[0036] In order to further improve the stability of the circular tube 14 during rotation, a circular limiting ring 21 is provided at one end of the inner protective shell 10 close to the circular tube 14, and a limiting groove 22 adapted to the circular limiting ring 21 is provided at one end of the circular tube 14 close to the inner protective shell 10, and the circular limiting ring 21 is sleeved in the limiting groove 22. When the circular tube 14 rotates, the blocking ring 16 and the circular limiting ring 21 can be used to limit the circular tube 14 to only rotate, and the displacement phenomenon when the circular tube 14 rotates can be limited, thereby improving the stability of the circular tube 14 during rotation.

[0037] In order to reduce the risk of the belt 25 falling off, positioning plates 23 are fixed on the outside of the circular tube 14 and on both sides of the belt 25. The turntable is provided with a positioning groove 24 adapted to the belt 25, which effectively reduces the belt 25 from falling off during operation, thereby improving the stability of the device.

[0038] In summary, the protection operation process of the drill rod 4 is simplified by the setting of the protection mechanism. When the drill rod 4 needs to be protected, the operator only needs to easily operate the magnetic ring 8 and the movable seat 2 to quickly install the bellows sleeve 7 on the outside of the drill rod 4, thereby making the entire protection process efficient and convenient. In addition, each time the drill rod 4 completes its work, it can be easily cleaned. The simplicity of this step further reduces the difficulty of maintenance. It effectively reduces the adhesion of impurities on the outside of the drill rod 4, thereby avoiding the corrosion problem of the drill rod 4 that may be caused by untimely cleaning, which not only realizes the protection of the drill rod 4, but also can significantly extend its service life.
