[0026] The outer wall cleaning assembly 3 includes a cleaning box 31 provided on the foundation 1, a carrying plate 32 is transversely provided in the cleaning box 31, and two bearing seats 33 are supported on the carrying plate 32. The two bearing seats 33 are rotatably connected to the mounting plates 34. The sides of the mounting plates 34 are provided with transmission plates 37. The opposite sides of the two transmission plates 37 are rotatably provided with transmission wheels 314. The transmission wheels 314 are sleeved with cleaning wire brushes 315.

[0027] An internal and external thread cleaning assembly 7 is also provided on the foundation 1 , and a movable trolley frame 8 is provided on the side of the internal and external thread cleaning assembly 7 .

[0028] In this embodiment, in actual use, the cleaning machine of the present application completely gets rid of the pure manual cleaning method during operation. After the drill tool to be cleaned enters the existing pipe rack, it can use the inclined wheel conveyor frame 2 to load the material, and use the outer wall cleaning component 3 and the internal and external thread cleaning component 7 to clean the outer wall and inner wall of the drill pipe body 6, and transmit them in sequence through the inclined wheel conveyor frame 2. When the drill pipe body 6 is transferred between the two cleaning stations, the pipe grabber and the pipe jacking machine are used for automated operation. In actual operation, the entire process of outer wall cleaning, transportation, thread cleaning at both ends, and unloading is fully automatic. Under normal circumstances, no manual intervention is required, and no physical labor is required. Personnel only need to monitor through a computer; it has abandoned the method of relying on a lot of manual labor to complete cleaning, and eliminated the negative effects caused by high physical exertion and unsafe factors under the existing situation.

[0029] In a preferred embodiment, taking into account the existing situation in the production enterprise, the cleaning machine of the present application is arranged;

[0030] 1. Still using the existing cleaning site and workshop, using the existing pipe rack and circulating water pool, to carry out fully automatic design and layout;

[0031] 2. Considering the factors of future overall relocation, while ensuring the necessary functions and effects, the project should be kept as simple as possible and the cost should be reduced as much as possible. The focus should be on cleaning the outer wall and internal and external threads. The existing conveyor line should be fully utilized and transformed into a supporting automatic line. The newly added foundation 1 of the outer wall cleaning device and the inclined wheel conveyor frame 2 of the thread cleaning device, including the outer wall cleaning component 3 of the conveyor mechanism, should not be reduced in quality standards and can be reused after the future relocation to avoid waste.

[0032] 3. After the drilling tool rack 4 to be washed is grabbed by the pipe grabber to the existing pipe rack, automatic assembly line cleaning and inspection can be realized. From entry to exit, there is no need to go back repeatedly, and the automatic transportation work continues. This changes the original process route of needing to grab the cleaned drilling tools from the inlet again through the pipe grabber, thereby improving the rationality of the overall process operation.

[0033] Furthermore, the traditional cleaning method still requires a pipe grabber to grab the cleaned drill tools from the inlet and transport them to the open-air pipe rack outside the workshop for inspection. The cleaning agent in this application completely changes the original outdated process route and completely improves the working environment of manual inspection after cleaning. After the pipe grabber grabs the drill tools to be cleaned, the drill tools continue to move inward without returning. At the same time, the automatic cleaning line enters the adjacent workshop from the inside, where inspection is carried out. This greatly improves the environment and is not affected by the cold winter and hot summer climates. This improves work efficiency, reduces the workload of the pipe grabber, improves the working environment, and reduces energy consumption.

[0034] Taking into account that a large amount of waste water will be generated during the actual cleaning process, the cleaning machine of the present application, in a preferred embodiment, utilizes existing pools and ditches to transform the necessary circulation system, increases and improves the cleaning and filtering capacity, and the cleaning wastewater is not discharged externally and is always recycled, which meets the requirements of environmental protection; the drill pipe body 6 after cleaning is output after the remaining water is emptied, and the emptied residual water returns to the circulating water pool without being carried outside, keeping the environment clean.

[0035] Specifically, refer to Figure 1-3 A positive and negative threaded rod 36 is horizontally passed through the two transmission plates 37 , and both ends of the positive and negative threaded rod 36 are respectively threadedly connected with nut members.

[0036] In this embodiment, in actual use, the two tooth directions on the forward and reverse screw rods 36 are respectively engaged with one of the transmission plates 37. Through the threaded setting between the forward and reverse screw rods 36 and the two transmission plates 37, when the forward and reverse screw rods 36 rotate, the transmission plates 37 engaged at both ends of the forward and reverse screw rods 36 can move in opposite directions or reverse directions along the spiral tooth directions of the forward and reverse screw rods 36, thereby realizing the adjustment of the distance between the two transmission plates 37.

[0037] Specifically, refer to Figure 1-4 A center seat 35 is provided on the bearing plate 32, and 351 is provided on both sides of the center seat 35.

At this time, through the cooperation between the transmission wheel 314 and the cleaning wire brush 315, the cleaning wire brush 315 can always press against the outer wall of the drill pipe body 6. When the transmission wheel 314 drives the cleaning wire brush 315 to rotate, the brushing of the drill pipe body 6 can be achieved.

[0039] Specifically, refer to Figure 1-4 The side of the transmission plate 37 is also equipped with a connecting plate 311, and the side of the connecting plate 311 is installed with a hinge shaft 312 and connected to a support arm 313 through the hinge shaft 312. The end of the support arm 313 is in triangular contact with the transmission plate 37.

[0040] In this embodiment, in actual use, the support arm 313 provided can cooperate with the compression spring 39 to press the transmission plate 37 tightly, so that the two cleaning wire brushes 315 can always be in contact with the wall of the drill pipe body 6. In a preferred embodiment, the support arm 313 provided can increase the clamping force on the top of the transmission plate 37 to ensure that the cleaning wire brush 315 can better clamp and brush the drill pipe body 6.

[0041] Specifically, refer to Figure 1-2 The side of the outer wall cleaning component 3 is equipped with a material rack 4, which is built by several pipe racks.

[0042] In this embodiment, in the actual cleaning operation, the cleaning object of this application is API standard drill pipe with a length of 2-7 / 8″~5-1 / 2″ and a length of 9m~10m; at the same time, after cleaning, the outer surface of the drill pipe tube shows the original color of the metal, without any spiral wire residue, and the internal and external threads of the joint are cleaned without any thread grease residue, oil stain, mud, etc. The material rack 4 provided can be used to support the drill pipe body 6 that has been cleaned.

[0043] Furthermore, the pipe grabber and pipe jacking machine in this application are both existing mature technologies, and their power connection and pneumatic connection methods are both existing technologies, and the control method can be achieved through simple programming by technicians in this field. It is common knowledge in this field and is only used without modification, so the control method and circuit connection will not be described in detail.

[0044] Specifically, refer to Figure 1-2 、 Figure 5 The internal and external thread cleaning assembly 7 includes a water tank 71, a high-pressure nozzle 72 is installed in the water tank 71, a high-pressure protective cover 73 is provided on the side of the water tank 71, and a groove for water outlet is opened on the side of the high-pressure protective cover 73. A low-pressure water pump 5 is installed on the foundation 1, and the low-pressure water pump 5 is connected to the high-pressure nozzle 72.

[0045] In this embodiment, after the drill pipe body 6 is brushed by the outer wall cleaning component 3, the drill pipe body 6 can be transferred to the internal and external thread cleaning component 7 for internal washing through the cooperation of the pipe grabber and the mobile trolley frame 8. At this time, through the connection between the high-pressure nozzle 72 and the low-pressure water pump 5, the high-pressure nozzle 72 can perform high-pressure flushing on the inner diameter of the drill pipe body 6.

[0046] The drill pipe cleaning machine of this utility model:

[0047] Step 1: In actual use, when the user needs to clean the drill pipe body 6, the inclined wheel conveying frame 2 is driven so that the inclined wheel conveying frame 2 can radially convey the drill pipe body 6. After the drill pipe body 6 is conveyed to the outer wall cleaning assembly 3 via the inclined wheel conveying frame 2, the outer wall cleaning assembly 3 can scrub the outside of the drill pipe body 6. During this period, the user drives the two oppositely arranged transmission wheels 314 to rotate by using a motor. At this time, the transmission connection between the transmission wheel 314 and the cleaning wire brush 315 enables the cleaning wire brush 315 to quickly scrub the outside of the drill pipe body 6, combined with the flushing of the external water source and the sequential scrubbing of multiple groups of outer wall cleaning assemblies 3, until the outside of the drill pipe body 6 is completely cleaned.

[0048] Step 2: After the drill pipe body 6 is cleaned by the outer wall cleaning assembly 3, the drill pipe body 6 can be transferred to the internal and external thread cleaning assembly 7 for internal cleaning through the cooperation of the pipe grabber and the mobile trolley frame 8. At this time, through the connection between the high-pressure nozzle 72 and the low-pressure water pump 5, the high-pressure nozzle 72 can perform high-pressure flushing on the inner diameter of the drill pipe body 6. After flushing, the drill pipe body 6 can be taken away by the pipe grabber again.
