[0041] Example:

[0042] See also Figures 1 to 5 The laser cleaning system for the outer surface of the drill pipe in the preferred embodiment of the present invention comprises a laser cleaning device 1 and a transmission device 2. The transmission device 2 is provided with multiple laser cleaning devices 1, and the laser cleaning device 1 is placed between the two transmission devices 2. Figure 1 As shown, in the preferred embodiment, the transmission devices 2 are arranged in a row, and a laser cleaning device 1 is provided, which is located between any two transmission devices 2, preferably located in the middle of multiple transmission devices 2. The drill rod to be cleaned can be transmitted through the transmission device 2 and continuously pass through the laser cleaning device 1.

[0043] Furthermore, in the preferred embodiment, the laser cleaning system for the outer surface of the drill pipe further comprises a dust removal device 3, a second connecting member (not shown in the figure) and a host computer (not shown in the figure), and the laser cleaning device 1 is connected to the dust removal device 3 via the second connecting member. Figure 2 As shown, a dust removal pipe seat 109 is provided on the laser cleaning device 1, and a connecting pipe can be selected as the second connecting piece. One end of the connecting pipe is connected to the dust removal pipe seat 109, and the other end is connected to the dust removal device 3. During cleaning, the dirt cleaned can be discharged to the connecting pipe by the dust removal pipe seat 109, and the impurities enter the dust removal device 3 along the connecting pipe. The dust removal device 3 is used to collect impurities during the cleaning process.

[0044] Among them, the upper computer can be specifically an electrical control system, which includes an electrical cabinet, PLC, HMI, circuit breaker, intermediate relay, AC contactor, switching power supply, button, indicator light, buzzer, terminal, connecting wire, etc., which is used to complete the action process logic control of the entire system. Specifically, existing technologies are used, mainly for manual control of the cleaning process or pre-setting the program to enable it to proceed automatically.

[0045] Specifically, if Figure 2 As shown, the laser cleaning device 1 in the preferred embodiment includes a frame 101, a cleaning member 102, a first mounting member 103 and an adjustment assembly 104 connected to the frame 101. The first mounting member 103 is connected to the adjustment assembly 104, and the cleaning member 102 is connected to the first mounting member 103.

[0046] When implementing it specifically, Figure 5 As shown, the cleaning element 102 can be a laser cleaning head, multiple of which can be provided, with a focal length of 300mm to 350mm, which can meet the specifications of the drill pipe being cleaned. In the preferred embodiment, since drill pipes are typically cylindrical, the first mounting element 103 is configured in a ring shape. A mounting bracket can be used, and the cleaning elements 102 are arranged on the first mounting element 103 at equal intervals, also forming a ring. This allows for comprehensive cleaning of cylindrical drill pipes. Specifically, five cleaning laser heads can be used, each capable of cleaning a section with an arc length of 30mm to 100mm. The cleaning laser heads are rotated 15° to illuminate the cleaning surface, and the intersection of the cleaning lines of two sections ensures at least 100% coverage of the circumference. Laser cleaning can achieve rapid cleaning of the outer surface of the pipe.

[0047] In other embodiments, sensors can be installed before and after the frame 101 to monitor the status of the drill rod to be cleaned passing through the laser cleaning device 1. The sensors can be connected to a host computer so that the operator can view the status. Furthermore, when the sensor detects the drill rod, the vacuum is activated first, and then the cleaning unit 102 starts to clean the pipe surface. After cleaning is completed, the cleaning unit 102 stops working. After the drill rod completely leaves the laser cleaning device 1, the dust removal device 3 is delayed and closed to ensure that dust is collected during the cleaning process.

[0048] Further, if Figure 2 As shown, in the preferred embodiment, the laser cleaning device 1 further includes a second mounting member 105, and the cleaning member 102 is mounted and connected to the first mounting member 103 via the second mounting member 105. Figure 2 As shown, the second mounting member 105 can be implemented as a mounting L-plate, which can better mount the cleaning member 102 on the first mounting member 103 .

[0049] More specifically, if Figure 3As shown, in the preferred embodiment, the adjustment assembly 104 includes a fixing assembly 1041 , a lifting assembly 1042 , a lifting plate 1043 and a first connecting member 1044 , and the first mounting member 103 is fixedly connected to the lifting plate 1043 .

[0050] The fixing assembly 1041 is fixedly connected to the frame 101, and the lifting assembly 1042 is connected to one fixing assembly 1041 at one end and fixedly connected to the lifting plate 1043 at the other end. The lifting plate 1043 is movably connected to the other fixing assembly 1041 via a first connecting member 1044. The lifting assembly 1042 can move in the vertical direction and drive the lifting plate 1043 to move in the vertical direction, thereby driving the first mounting member 103 fixedly connected to the lifting plate 1043 to move in the vertical direction, and further driving the cleaning member 102 connected to the first mounting member 103 to move up and down.

[0051] In a specific implementation, the lifting plate 1043 can be an integrally formed frame or a split-formed frame, which corresponds in size to the first mounting member 103 so that the first mounting member 103 can be well connected thereto. Two fixing components 1041 can be provided, located on both sides of the same side of the lifting plate 1043, preferably on the side of the lifting plate 1043 not connected to the first mounting member 103. The first connecting member 1044 can optionally be a guide block. When the lifting assembly 1042 drives the lifting plate 1043 to move up and down, the first connecting member 1044 is connected to the fixing component 1041 on the other side so that the lifting plate 1043 can be supported on both sides and can move up and down stably. Furthermore, a linear slide rail can be provided on the side of the fixing component 1041 connected to the lifting assembly 1042 facing the lifting plate 1043 to match and connect with the lifting plate 1043, so that the movement of the lifting plate 1043 is more stable and reliable.

[0052] Specifically, in the preferred embodiment, the lifting assembly 1042 includes a lifting screw 10421 and a lifting nut 10422. The lifting screw 10421 is mounted on the top of the fixed assembly 1041, and the lifting nut 10422 can move vertically on the lifting screw 10421. One side of the lifting nut 10422 is fixedly connected to the lifting plate 1043. It is understood that the lifting screw 10421 can be manually or electrically controlled, and the rotation of the lifting screw 10421 causes the lifting nut 10422 to rotate and move up and down.

[0053] Preferably, in the preferred embodiment, the lifting screw 10421 is electrically controlled, and the lifting assembly 1042 also includes a second driving member 10423. When the second driving member 10423 is implemented, a driving motor can be optionally selected. The second driving member 10423 drives the lifting screw 10421 to rotate so that the lifting nut 10422 moves in the vertical direction on the lifting screw 10421, thereby driving the lifting plate 1043 fixedly connected to the lifting nut 10422 to move in the vertical direction, and then driving the first mounting member 103 fixedly connected to the lifting plate 1043 to move in the vertical direction.

[0054] Among them, such as Figure 3 As shown, in the preferred embodiment, the fixing assembly 1041 includes a guide post 10411 and a righting post 10412, both of which are fixedly connected to the frame 101. The righting post 10412 is located between the lifting plate 1043 and the guide post 10411. The provision of these two posts, which cooperate with each other, can prevent the lifting plate 1043 from tilting or not moving vertically during movement.

[0055] In addition, if Figure 2 As shown, in a preferred embodiment, the laser cleaning device 1 further includes a dust hood 106 and a protective cover 107. The dust hood 106 is connected to one side of the frame 101 connected to the cleaning element 102, and the protective cover 107 is connected to the other side of the frame 101. The arrangement of the dust hood 106 and the protective cover 107 can ensure a cleaner cleaning process and prevent the cleaning process from being affected. Both of the dust hoods have through holes to allow the drill rod with clear material to pass through.

[0056] More preferably, in the preferred embodiment, the laser cleaning device 1 further includes a first protective member 108, which is disposed at the bottom of the cleaning member 102 and can prevent impurities from splashing onto the cleaning member 102 during cleaning. In specific implementation, the first protective member 108 can be a laser cleaning head mounting plate.

[0057] Furthermore, if Figure 4 As shown, in a preferred embodiment, the transmission device 2 includes a base 201 and a transmission wheel 202 connected to the base 201. A first drive member 203 is connected to one end of the transmission wheel 202. The first drive member 203 drives the transmission wheel 202 to rotate, and the drill rod to be cleaned can be placed on the transmission wheel 202. In a specific implementation, the first drive member 203 can optionally be a reduction motor, and the transmission wheel 202 can be a V-shaped roller, which allows the drill rod to be placed on it. When the first drive member 203 is in operation, it rotates the transmission wheel 202, thereby moving the drill rod forward or backward under the rotation of the transmission wheel 202, thus performing a transmission function. At the same time, the first drive member 203 ensures that the rotation speed of the transmission wheel 202 is controllable and consistent, so that the drill rod to be cleaned can move at a uniform speed.

[0058] More specifically, in the preferred embodiment, the transmission device 2 further includes a bearing seat 204 and a third connecting member 205. The bearing seat 204 is fixedly connected to the base 201, and the transmission wheel 202 is connected to the bearing seat 204 on both sides. The transmission wheel 202 is connected to the first driving member 203 via the third connecting member 205. A second protective member 206 is provided corresponding to the third connecting member 205. The second protective member 206 is connected to the base 201 and can protect the third connecting member 205. In a specific embodiment, the third connecting member 205 is a coupling, and the second protective member 206 is a protective cover, thereby enabling the rotation of the transmission wheel 202.

[0059] During operation, the present drill rod outer surface laser cleaning system pre-adjusts the focus of the cleaning element 102 to the center of the drill rod to be cleaned using an adjustment assembly 104, ensuring that the cleaning element 102 is aligned with the center height of the drill rod being cleaned. Multiple transmission devices 2 uniformly transport the cleaned drill rod through the laser cleaning device 1, completing the cleaning and transferring it to the next process. A dust removal device 3 is pre-activated before the drill rod is cleaned and then deactivated afterward, ensuring that dust generated during the laser cleaning process is collected.

[0060] Compared with manual cleaning methods, the drill pipe outer surface laser cleaning system in the present invention is more efficient, has higher cleaning accuracy, is safer and more environmentally friendly. Through intelligent sensing and automatic control, the labor cost and cleaning effect are guaranteed, and the production efficiency and average production quality are improved. In addition, the adjustment component in the laser cleaning device cooperates with other structures to adjust the automatic centering of the focal length of the cleaning part, which can adapt to the uneven cleaning of drill pipes of different specifications due to different outer diameters. The transmission device transmits the cleaned drill pipe through the laser cleaning device at a uniform speed to ensure that the equipment cleans the pipe surface at a uniform speed. Multiple cleaning parts are evenly distributed on the laser cleaning device in the circumferential direction, which can meet the requirements of complete coverage of the surface of the drill pipe to be cleaned. The dust removal device is delayed to close before and after cleaning to ensure dust collection during the cleaning process. Furthermore, the laser cleaning system for the outer surface of the drill pipe is installed in a transmission line interlaced manner, which is not only compact in structure but also more convenient for on-site modification.

[0061] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
