Detailed Implementation

[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] This utility model provides a pipe thread cleaning device, and several embodiments are given below to describe the pipe thread cleaning device provided by this utility model in detail.

[0021] The pipe thread cleaning device provided in this embodiment, such as Figures 1 to 6As shown, it includes a clamping assembly 1 and a cleaning assembly; the clamping assembly 1 can clamp the pipe; the cleaning assembly includes a rotating mechanism 2, a liquid spraying mechanism 3 and a gas spraying mechanism 4; the liquid spraying mechanism 3 and the gas spraying mechanism 4 are both mounted on the rotating mechanism 2, and the rotating mechanism 2 can drive the liquid spraying mechanism 3 and the gas spraying mechanism 4 to rotate around the axis of the rotating mechanism 2; the liquid spraying mechanism 3 can spray liquid onto the pipe threads, and the gas spraying mechanism 4 can spray gas onto the pipe threads.

[0022] When cleaning pipe threads, the pipe is clamped by clamping assembly 1, with the pipe thread located at the end of the pipe away from clamping assembly 1 and facing the rotating mechanism 2. The spraying mechanism 3 and the air spraying mechanism 4 are located outside the pipe thread. The spraying mechanism 3 sprays liquid onto the pipe thread, and the rotating mechanism 2 drives the spraying mechanism 3 to rotate around the axis of the rotating mechanism 2, thereby spraying liquid onto the pipe thread circumferentially to clean the pipe thread. Subsequently, the air spraying mechanism 4 sprays gas onto the pipe thread, and the rotating mechanism 2 drives the air spraying mechanism 4 to rotate around the axis of the rotating mechanism 2, thereby spraying gas onto the pipe thread circumferentially to perform air spray cleaning on the pipe thread.

[0023] The pipe thread cleaning device provided in this embodiment can replace manual cleaning of pipe threads, which is less time-consuming, more efficient, and provides higher cleaning quality, enabling the pipe threads to be thoroughly cleaned and preventing leakage and detachment of the sealant after the pipe threads are sealed with adhesive.

[0024] Furthermore, the clamping assembly 1 includes a first driving member 11, a guide member 12, and two clamping members 13 arranged opposite to each other; the two clamping members 13 are slidably connected to the guide member 12 respectively, and the first driving member 11 can drive the two clamping members 13 to move closer or further away from each other so that the two clamping members 13 cooperate to clamp the pipe.

[0025] The first driving component 11 can be an electric push rod or a cylinder or any other suitable form.

[0026] Two clamping members 13 are slidably connected to the guide member 12, and the two clamping members 13 can slide along the extension direction of the guide member 12. The first driving member 11 drives the two clamping members 13 to move closer or further away from each other, so that the two clamping members 13 cooperate to clamp the pipe. By using the guide member 12 to guide the movement path of the clamping members 13, the two clamping members 13 can accurately clamp or release the pipe.

[0027] The number of first driving components 11 can be one or two.

[0028] For example, there are two first driving members 11. One first driving member 11 is connected to a first clamping member 13 to drive the first clamping member 13 to slide along the guide member 12. The other first driving member 11 is connected to another first clamping member 13 to drive the other first clamping member 13 to slide along the guide member 12.

[0029] For example, there is one first driving member 11. The first driving member 11 can be a motor. The motor is connected to the lead screw. The motor can drive the lead screw to rotate around the axis of the lead screw. The lead screw includes a first threaded segment and a second threaded segment arranged sequentially at intervals along its axis. The thread directions of the first threaded segment and the second threaded segment are opposite. One first clamping member 13 is threadedly connected to the first threaded segment, and another first clamping member 13 is threadedly connected to the second threaded segment.

[0030] The guide component 12 can be a guide rod, a guide rail, or any other suitable form.

[0031] The number of guide members 12 can be one or more. When there is only one guide member 12, the middle part of the clamping member 13 can be slidably sleeved on the guide member 12.

[0032] Furthermore, there are two guide members 12; the clamping assembly 1 also includes a sliding bracket 16, one end of which is slidably sleeved on one guide member 12, and the other end of which is slidably sleeved on another guide member 12, and the clamping member 13 is fixedly connected to the sliding bracket 16.

[0033] The two guide members 12 are arranged parallel to each other and spaced apart. One end of the sliding bracket 16 is slidably sleeved on one guide member 12, and the other end of the sliding bracket 16 is slidably sleeved on the other guide member 12. Both ends of the sliding bracket 16 are slidably connected to the guide members 12, which allows both ends of the sliding bracket 16 to be guided, thereby further improving the accuracy of guiding the clamping member 13.

[0034] Furthermore, the rotating mechanism 2 includes a cover 21 and a second driving member 22, which is connected to the cover 21 and can drive the cover 21 to rotate around the axis of the cover 21; the liquid spraying mechanism 3 includes a liquid pipe 31, which is fixed to the inner wall of the cover 21 and is provided with a liquid nozzle 32; the air spraying mechanism 4 includes a gas pipe 41, which is fixed to the inner wall of the cover 21 and is provided with a gas nozzle 42.

[0035] The second driving component 22 can be an electric motor, a hydraulic motor, or any other suitable form.

[0036] The output shaft of the second driving component 22 is fixedly connected to the cover 21, thereby driving the cover 21 to rotate around the axis of the cover 21. The inner wall of the cover 21 is arranged facing the pipe thread. The liquid pipe 31 and the gas pipe 41 are respectively fixed on the inner wall of the cover 21, so that the liquid pipe 31 and the gas pipe 41 can rotate synchronously with the cover 21.

[0037] The liquid in the liquid pipeline 31 is sprayed onto the pipe thread through the liquid nozzle 32, and the gas in the gas pipeline 41 is sprayed onto the pipe thread through the gas nozzle 42.

[0038] When cleaning pipe threads, first use liquid spray to clean the oil and impurities on the thread surface, and then use gas spray to further remove impurities and liquid from the thread surface and keep the pipe thread surface dry.

[0039] The cleaning assembly also includes components such as a water tank, a water pump, a relay, and a solenoid valve. The water tank, water pump, and liquid pipeline 31 are connected in sequence, as are the air source, solenoid valve, and gas pipeline 41. When the enclosure 21 begins to rotate in the first direction, the first detection probe detects this rotation and sends a signal to the controller. The controller then controls the relay and water pump to start operating, thereby performing the spray liquid cleaning operation. When the enclosure 21 begins to rotate in the second direction, the second detection probe detects this rotation and sends a signal to the controller. The controller then controls the relay and water pump to stop operating and opens the solenoid valve, thus maintaining the connection between the gas pipeline 41 and the air source for the spray gas cleaning operation. The first and second directions are opposite; in this embodiment, the first direction is counterclockwise, and the second direction is clockwise. The first and second detection probes can be existing detection devices such as cameras or position switches, which will not be elaborated further here.

[0040] Furthermore, the liquid pipeline 31 is annular, and there are multiple liquid nozzles 32, which are evenly spaced along the circumference of the liquid pipeline 31; the gas pipeline 41 is annular, and there are multiple gas nozzles 42, which are evenly spaced along the circumference of the gas pipeline 41.

[0041] The gas pipeline 41 can be sleeved outside the liquid pipeline 31, and the liquid pipeline 31 can also be sleeved outside the gas pipeline 41.

[0042] The liquid pipeline 31 is annular, allowing multiple liquid nozzles 32 to be positioned at multiple locations facing the pipeline threads. Similarly, the gas pipeline 41 is annular, allowing multiple gas nozzles 42 to be positioned at multiple locations facing the pipeline threads. Spraying liquid onto the pipeline threads through multiple liquid nozzles 32 improves the liquid cleaning effect, while spraying gas onto the pipeline threads through multiple gas nozzles 42 improves the gas cleaning effect. Furthermore, the pipe thread cleaning device also includes a moving component 5; the moving component 5 is connected to the clamping component 1, and the moving component 5 can drive the clamping component 1 to move toward or away from the rotating mechanism 2.

[0043] When the clamping component 1 is in the first preset position, the pipe is placed into the clamping component 1, the clamping component 1 clamps the pipe, and the moving component 5 drives the clamping component 1 to move toward the rotating mechanism 2 until the clamping component 1 moves to the second preset position. Then, the cleaning component is activated to clean the threads. After the cleaning operation is completed, the moving component 5 drives the clamping component 1 back to the first preset position, the clamping component 1 is released, and the pipe is removed.

[0044] By using the moving component 5 to move the clamping component 1 between the first preset position and the second preset position, work efficiency can be further improved.

[0045] Furthermore, the clamping component 1 is installed at the first preset position and cleaned at the second preset position, which facilitates the operation of clamping the pipe and prevents the pipe from colliding with the cleaning component during the process of inserting the pipe into the clamping component 1.

[0046] Furthermore, the moving component 5 includes a slide rail 51 and a third driving member 52; the clamping component 1 has mounting members 14 at both ends; the mounting members 14 are slidably connected to the slide rail 51, and the third driving member 52 is connected to the mounting members 14, and the third driving member 52 can drive the mounting members 14 to slide along the slide rail 51.

[0047] Specifically, the two ends of the guide member 12 are respectively fixed by mounting members 14. One mounting member 14 is slidably connected to a slide rail 51, and a third driving member 52 is fixedly connected to one mounting member 14. The third driving member 52 drives one mounting member 14 to slide along the slide rail 51. The other mounting member 14 is slidably connected to another slide rail 51, and another third driving member 52 is fixedly connected to another mounting member 14. The other third driving member 52 drives the other mounting member 14 to slide along the slide rail 51.

[0048] The third driving component 52 can be a cylinder or an electric push rod, etc. In this embodiment, the third driving component 52 is a rodless cylinder slider. A slider 15 is fixed to the bottom of the mounting component 14. The slider 15 is slidably connected to the slide rail 51, and the rodless cylinder slider is fixedly connected to the mounting component 14.

[0049] In addition, a tank chain 53 is provided on the outside of each moving component 5 to protect the wire harness and air tube from reciprocating with the clamping mechanism.

[0050] Furthermore, the pipe thread cleaning device also includes a control component 6; the control component 6 includes a first position detector 61, a second position detector 62, and a third position detector 63; the first position detector 61 can detect whether the clamping component 1 is located at a first preset position, and when the clamping component 1 is located at the first preset position, the control component 6 can control the clamping component 1 to clamp or release the pipe; the second position detector 62 can detect whether the clamping component 1 has moved to a second preset position, and when the clamping component 1 has moved to the second preset position, the control component 6 can control the moving component to stop moving; the third position detector 63 can detect whether the clamping component 1 has moved to the first preset position, and when the clamping component 1 has moved to the first preset position, the control component 6 can control the moving component to stop moving.

[0051] The pipe is placed between two clamping members 13. The first position detector 61 detects that the mounting member 14 is in the first preset position. The controller controls the clamping assembly to be energized. Press the clamping button. After the two clamping members 13 clamp the pipe, press the cleaning operation button. At this time, the mounting member 14 is in the first preset position. Under the control of the solenoid valve group, the rodless cylinder slider drives the clamping assembly 1 to move towards the rotating mechanism 2. When the mounting member 14 moves to the second preset position, the second position detector 62 detects that the mounting member 14 has moved to the second preset position. The controller controls the solenoid valve group to stop the rodless cylinder slider. The moving assembly 5 no longer drives the clamping assembly 1 to move. Then the pipe threads are cleaned. After the pipe threads are cleaned, the clamping assembly 1 is driven by the moving assembly 5 to return to the first preset position. When the mounting member 14 returns to the first preset position, the third position detector 63 detects that the mounting member 14 has moved to the first preset position. The controller controls the solenoid valve group to stop the rodless cylinder slider. The moving assembly 5 no longer drives the clamping assembly 1 to move.

[0052] The controller will only energize the clamping assembly when the first position detector 61 detects that the mounting component 14 is in the first preset position. The controller will not energize the clamping assembly at other positions, so that the clamping assembly can only release or clamp the pipe at the first preset position.

[0053] Furthermore, the control component 6 also includes a fourth position detector 64, a fifth position detector 65, and a sixth position detector 66. The fourth position detector 64 can detect whether the clamping component 1 has moved to a second preset position. When the clamping component 1 moves to the second preset position, the control component 6 can control the spraying mechanism 3 to run and control the rotating mechanism 2 to rotate in the first direction. The fifth position detector 65 can detect whether the angular displacement of the rotating mechanism 2 in the first direction reaches a first preset value. When the angular displacement of the rotating mechanism 2 in the first direction reaches the first preset value, the control component 6 can control the spraying mechanism 3 to stop running, control the jetting mechanism 4 to run, and control the rotating mechanism 2 to rotate in the second direction. The sixth position detector 66 can detect whether the angular displacement of the rotating mechanism 2 in the second direction reaches a second preset value. When the angular displacement of the rotating mechanism 2 in the second direction reaches the second preset value, the control component 6 can control the rotating mechanism 2 and the jetting mechanism 4 to stop running.

[0054] A detection block can be set on the cover 21 so that the detection block works in conjunction with the fifth position detector 65 and the sixth position detector 66 to detect the angular displacement of the rotating mechanism 2.

[0055] When the moving component 5 moves the clamping component 1 to the second preset position, the fourth position detector 64 detects that the mounting component 14 has moved to the second preset position. The controller controls the spraying mechanism 3 to run and controls the rotating mechanism 2 to rotate in the first direction for liquid spray cleaning. When the angular displacement of the rotating mechanism 2 in the first direction reaches the first preset value, the fifth position detector 65 detects that the angular displacement of the rotating mechanism 2 in the first direction reaches the first preset value and controls it to stop the spraying mechanism 3, controls the jetting mechanism 4 to run, and controls the rotating mechanism 2 to rotate in the second direction for gas spray cleaning. When the angular displacement of the rotating mechanism 2 in the second direction reaches the second preset value, the sixth position detector 66 detects that the angular displacement of the rotating mechanism 2 in the second direction reaches the second preset value. The control component 6 controls the rotating mechanism 2 and the jetting mechanism 4 to stop running. The cleaning is completed, and the clamping component 1 returns to the first preset position under the drive of the moving component 5.

[0056] The first and second preset values ​​can both be 180°, or any other suitable angle value.

[0057] The rotating mechanism 2, the spraying mechanism 3, and the jetting mechanism 4 can only work when the clamping assembly 1 is in the second preset position; they cannot work in other positions.

[0058] The first position detector, second position detector, third position detector, fourth position detector, fifth position detector, and sixth position detector can be any suitable detection device such as a position switch or photoelectric position switch.

[0059] Furthermore, the pipe thread cleaning device also includes a frame 7 and a splash guard 8; the clamping assembly 1, the cleaning assembly and the moving assembly 5 are all disposed on the top surface of the frame 7, and the splash guard 8 covers the top surface of the frame 7.

[0060] The splash guard 8 covers the top surface of the frame 7, and the splash guard 8 and the top surface of the frame 7 form a sealed space, which can collect and process impurities such as iron filings and dust, avoid pollution control, and prevent iron filings from flying and injuring operators.

[0061] In this embodiment, the frame 7 is welded from 50mm*5mm carbon steel square tubing, providing high structural strength. The dimensions of the frame 7 are 1050mm*1050mm*528mm. This pipe thread cleaning device can clean various pipe threads within the φ35mm-105mm range, offering wide adaptability. Through the relative movement between the two clamping members 13, it can be applied to pipes of different diameters without the need for frequent clamp replacements.

[0062] The splash guard 8 is made of transparent acrylic sheet and is completely sealed in all directions except for the opening in the direction of the loading and unloading pipe, to prevent iron filings and dust from polluting the air. The water tank and electrical system can be set on the side of the frame 7. A collection tank is also set on the top surface of the frame 7. When the clamping assembly 1 is in the second preset position, the collection tank is located below the pipe and can collect cleaning wastewater.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
