[0037] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0038] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0040] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0041] This invention provides a multi-size drill pipe coupling adaptability installation testing device, which can be used for adaptability installation testing of drill pipe couplings of various sizes, so as to improve the efficiency and quality of uncoupling drill pipe couplings on site.

[0042] like Figure 1 and Figure 2 As shown, the multi-size drill pipe coupling adaptability installation test device includes a translational lifting platform 1, an image acquisition device 2, and an industrial control computer 3. The translational lifting platform 1 is equipped with a lower drill pipe fixing device 5, which is used to install a simulated lower drill pipe top coupling. The translational lifting platform 1 can drive the lower drill pipe fixing device 5 to move along the Z and X directions, which are the vertical and horizontal directions, respectively. Through the movement of the lower drill pipe fixing device 5, the simulated lower drill pipe top coupling is aligned with the upper drill pipe bottom coupling, facilitating the on-site uncoupling and coupling operations of the two drill pipes. The image acquisition device 2 is positioned directly opposite the lower drill pipe fixing device 5. The image acquisition device 2 can acquire image data, including images of the end face positions of the simulated lower drill pipe top coupling and the upper drill pipe bottom coupling; thus, it can obtain image information showing the alignment of the simulated lower drill pipe top coupling with the upper drill pipe bottom coupling. The industrial control computer 3 communicates with the translational lifting platform 1 and the image acquisition device 2. The industrial control computer 3 is used to control the movement of the translational lifting platform 1 and receive image data from the image acquisition device 2, and then upload the image data to the controller. The controller can parse the image data into the actual alignment information of the top coupling of the lower drill rod and the bottom coupling of the upper drill rod on site, which is used to guide the on-site drive to align the upper and lower drill rods for the upper and lower coupling operations.

[0043] The multi-size drill pipe coupling adaptability installation test device provided by this invention, by setting a lower drill pipe fixing device 5 on the translational lifting platform 1, can realize the movement and positioning of the top coupling of the simulated lower drill pipe. This facilitates the image acquisition device to obtain image data of the relative positional relationship between the simulated lower and upper drill pipes to form accurate positioning information. After receiving the image data including the positioning information, the controller can feed back to the robotic arm that grips the upper drill pipe and the large tongs responsible for coupling, ensuring accurate gripping of the upper drill pipe on site and accurate matching of the male and female threaded joints, thereby improving the quality and efficiency of coupling operation and enhancing the safety of coupling operation.

[0044] In this device, the image acquisition device 2 is generally an industrial camera. To improve the image quality of the industrial camera, in some embodiments, the multi-size drill pipe coupling adaptability installation test device also includes a light source assembly 4. The light source assembly 4 and the image acquisition device 2 are respectively located on both sides of the translational lifting platform 1. The light source assembly 4 is used to illuminate the image acquisition area of ​​the image acquisition device 2. Figure 1 As shown, the light source assembly 4 and the image acquisition device 2 are respectively located on both sides of the translational lifting platform 1, and are adjusted to a suitable height by their respective brackets to obtain clear image data. The light source assembly 4 is electrically connected to the industrial control computer 3 to control the start and stop of the light source assembly 4. The industrial control computer 3 is selected to be a gigabit network port transmission industrial control computer 3, and the controller is a computer control terminal. The industrial control computer 3 is connected to the controller via a network cable.

[0045] In some embodiments, the lower drill pipe fixing device 5 is detachably connected to the translational lifting platform 1, allowing the lower drill pipe fixing device 5 to be replaced with a suitable fixing structure, such as a variable-size clamp, according to the size of the simulated lower drill pipe, thereby enabling adaptability installation testing of couplings for drill pipes of various sizes. Detachable connection methods include, but are not limited to, snap-fit ​​or screw-fit connections.

[0046] In some embodiments, the translational lifting platform 1 includes a base 11, a lifting drive assembly 12, a support plate 13, and a mounting plate 14. The lifting drive assembly 12 is disposed on the base 11. The support plate 13 is disposed at the output end of the lifting drive assembly 12, and the lifting drive assembly 12 can drive the support plate 13 to move up and down along the Z direction. The mounting plate 14 is slidably mounted on the support plate 13, and the sliding direction of the mounting plate 14 is the X direction. The mounting plate 14 is provided with a lower drill rod fixing device 5.

[0047] like Figure 1 As shown, by moving the lifting platform 1, the position of the lower drill rod fixing device 5 in the Z and X directions can be adjusted. Combined with the image acquisition device 2, the height of the simulated upper and lower drill rods (upper clamp) and the size of the connection gap of the simulated upper and lower drill rod couplings (unclamp) can be identified. This can solve the problems of positioning and measuring the size of the upper and lower drill rods, and thus guide the tongs or driller to accurately grasp the upper and lower drill rods, achieving accurate and efficient drilling and hoisting operations.

[0048] In some embodiments, the lifting drive assembly 12 includes a servo motor 121, a first gearbox 122, and a second gearbox 123. The servo motor 121 has two output ends, which are respectively connected to a first screw 124 and can drive the first screw 124 to rotate. The input end of the first gearbox 122 is connected to the end of the first screw 124 away from the servo motor 121, and the output end of the first gearbox 122 is connected to a second screw 125. The second screw 125 is arranged along the Y direction, which is perpendicular to the X direction. The second gearbox 123 is located below the support platform 13. The input end of the second gearbox 123 is connected to the end of the second screw 125 away from the first gearbox 122, and the first output end of the second gearbox 123 is connected to a first lifting screw 126. The first lifting screw 126 is arranged along the Z direction, and the top end of the first lifting screw 126 is movably connected to the support platform 13.

[0049] Combination Figure 1 The servo motor 121 has a bidirectional output end, with each output end connected to a first screw 124. The two first screws 124 are coaxially arranged and can rotate synchronously. The rotational motion of the first screw 124 is reversed by 90° after passing through the first gearbox 122 and transmitted to the second screw 125. The rotational motion of the second screw 125 is reversed by 90° after passing through the second gearbox 123 and transmitted to the first lifting screw 126. The top end of the first lifting screw 126 is movably connected to the support platform 13. The rotational motion of the first lifting screw 126 is converted into the movement motion of the support platform 13, realizing lifting. It can be understood that by adjusting the position of the second gearbox 123 below the support platform 13, balanced support and stable lifting control of the support platform 13 can be achieved. The servo motor 121 is connected to the industrial control computer 3 for communication. The industrial control computer 3 controls the output of the servo motor 121 to achieve automated control, making the control process more precise and efficient.

[0050] In some embodiments, the lifting drive assembly 12 further includes a third screw 127 and a third gearbox 128. The third screw 127 is connected to the second output end of the second gearbox 123 and is arranged along the Y direction. The third gearbox 128 is located below the support platform 13 and spaced apart from the second gearbox 123. The input end of the third gearbox 128 is connected to the other end of the third screw 127 away from the second gearbox 123, and the output end of the third gearbox 128 is connected to the second lifting screw 129. The second lifting screw 129 is arranged along the Z direction, and the top end of the second lifting screw 129 is movably connected to the support platform 13. The initial heights of the first lifting screw 126 and the second lifting screw 129 are the same.

[0051] Combination Figure 1Two second gearboxes 123 and two third gearboxes 128 are symmetrically arranged below the support platform 13 and at its four corners. This allows the two first lifting screws 126 and two second lifting screws 129 to provide four-point support and lifting drive for the support platform 13. More simply and conveniently, the first lifting screws 126 and 129 have identical structures and are positioned on both sides of the sliding direction of the mounting plate 14, providing stable support. The output ends of the servo motor 121 are symmetrically arranged on both sides to achieve synchronous and stable lifting drive for the support platform 13. The second gearbox 123 has a first output end and a second output end. The second output end and input end are coaxially arranged along the Y-axis, while the first output end is vertical and connected to the bottom end of the first lifting screw 126. The first gearbox 122 and the third gearbox 128 each have mutually perpendicular input and output ends to achieve 90° reversal of the transmission direction.

[0052] It should be noted that the first gearbox 122, the second gearbox 123, and the third gearbox 128 involved in the embodiments of the present invention are all gear transmission assemblies used to reverse the transmission motion output. The specific configuration of the gear transmission assembly is generally known in the art, and will not be described in detail in the embodiments of the present invention.

[0053] In some embodiments, the translational lifting platform 1 further includes a motion drive assembly 15, which is disposed on the support platform 13 and configured to drive the mounting plate 14 to slide along the X direction. Depending on the actual situation, the motion drive assembly 15 can be manually driven or electrically driven. When electrically driven, it can be automatically controlled by communicating with an industrial control computer 3.

[0054] In some embodiments, the motion drive assembly 15 includes a fixing member 151 and a fourth screw 152. The fixing member 151 is disposed on the support plate 13 and has an internal threaded hole. The fourth screw 152 passes through the fixing member 151 and is threadedly connected to the fixing member 151. One end of the fourth screw 152 is movably connected to the mounting plate 14, and the other end of the fourth screw 152 is provided with a rocker arm 153.

[0055] like Figure 1 The fixing member 151 can be a nut, which is fixedly mounted on the support plate 13. When the rocker arm 153 drives the fourth screw 152 to rotate, the fourth screw 152 can drive the mounting plate 14 to move, realizing the sliding drive control of the mounting plate 14. Alternatively, the fixing member 151 can also be mounted on the mounting plate 14, with the fourth screw 152 movably connected to the support plate 13. When the fourth screw 152 rotates, it drives the fixing member 151 to move the mounting plate 14. The movable connection can be a rotating connection or a hinge, etc.

[0056] In some embodiments, the upper surface of the support plate 13 is provided with a groove 131, and the mounting plate 14 is slidably connected in the groove 131.

[0057] like Figure 1 and Figure 2 The slide groove 131 can limit the sliding direction of the mounting plate 14, ensuring that the mounting plate 14 slides along the X direction. Preferably, the slide groove 131 extends through both ends of the support platform 13 along the sliding direction of the mounting plate 14, so that the mounting plate 14 has a large sliding distance.

[0058] In some embodiments, the mounting plate 14 has stepped grooves 141 on both sides of its side edges, and the two groove walls of the stepped grooves 141 slide in contact with the groove wall of the slide groove 131 and the plate surface of the support plate 13, respectively.

[0059] like Figure 2 As shown, the stepped groove 141 is a right-angled groove structure, allowing the mounting plate 14 to be pressed onto the surface of the support plate 13 from top to bottom. The vertical groove wall of the stepped groove 141 slides in contact with and abuts against the groove wall of the sliding groove 131, while the horizontal groove wall of the stepped groove 141 slides in contact with the plate surface (upper surface) of the support plate 13. Preferably, along the Z-direction, the groove depth of the stepped groove 141 is equal to the groove depth of the sliding groove 131, thereby allowing the bottom surface of the mounting plate 14 to contact the bottom of the sliding groove 131. This increases the sliding contact area between the mounting plate 14 and the support plate 13, facilitating better support of the mounting plate 14.

[0060] Using the multi-size drill pipe coupling adaptability installation testing device provided in this embodiment of the invention, during installation testing, the light source assembly 4 is first turned on, then the translational lifting platform 1 is driven and controlled to adjust the position of the lower drill pipe fixing device 5 to align the simulated lower drill pipe with the upper drill pipe. The image acquisition device 2 measures the image data under alignment and sends it to the industrial control computer 3 and the controller. Based on the image data, the controller obtains parameter data under alignment, including the distance between the image acquisition device 2 and the outer surface of the simulated lower drill pipe, the height of the translational lifting platform 1, the end face position of the top coupling of the simulated lower drill pipe, and the end face position of the bottom coupling of the upper drill pipe. Based on this parameter data, during on-site coupling installation and removal, the position of the upper drill pipe is adjusted according to the simulated parameter data to align the upper and lower drill pipes, thereby ensuring accurate positioning of the coupling before coupling installation and removal. The pliers accurately grip the upper and lower drill pipes, and the male and female threaded connectors accurately match, ensuring the quality and efficiency of coupling installation and removal work and improving work safety.

[0061] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
