Detailed Implementation

[0010] An automated tubing measurement and lowering device, such as Figures 1-4 As shown, the tubing transfer equipment and tubing lowering method include a base 70, a receiving device 80, a control module 100, and a transfer device 90. The receiving device 80 is rotatably mounted on the base 70 and includes a receiving assembly 81. The receiving assembly 81 includes a receiving structure 811 and at least two limiting parts 812 disposed on the receiving structure 811. The at least two limiting parts 812 are arranged opposite to each other and surround the receiving structure 811 to form a receiving space for receiving the tubing 110. At least one limiting part 812 can move toward or away from the other limiting part 812 to adjust the size of the receiving space. At least one sensing structure is provided on each limiting part 812. The control module 100 is connected to the sensing structure. When the sensing structures on at least two limiting parts 812 sense the tubing 110, the control module obtains the length of the tubing 110 based on the sensing time of the sensing structures. The transfer device 90 is mounted on the base 70 and is used to transfer the tube column 110 after measurement to a preset position.

[0011] In this way, after the receiving device 80 receives the pipe column 110, the receiving space is adjusted until the limiting part 812 abuts against the pipe column 110, allowing the length of the pipe column 110 to be measured, so as to adjust the parameters of the pipe lifting and lowering operation. After the length of the pipe column 110 is measured, the receiving device 80 drives the pipe column 110 to rotate relative to the machine base 70, so as to transport the pipe column 110 to the position of the transfer device 90. At this time, the transfer device 90 transfers the pipe column 110 to the preset position, so as to facilitate the workers to perform the pipe lowering operation, thereby solving the problem of low efficiency in the handling and transfer of pipe columns in the prior art and reducing the labor intensity of the workers. In particular, since the pipe column length information obtained by the control module 100 facilitates the subsequent pipe lifting and lowering operation, the reliability of the pipe lifting and lowering operation is improved.

[0012] In this embodiment, the operator first adjusts the size of the receiving space to be larger than the size of the pipe column 110, so that the operator can place the pipe column 110 in the receiving space along the extension direction of the receiving device 80. After the pipe column 110 is placed, the control module 100 controls at least one limiting part 812 to move toward another limiting part 812 until the sensing structure of the limiting part 812 contacts the pipe column 110. At this time, the control module 100 controls the limiting part 812 to stop moving and obtains the length of the pipe column 110 based on the sensing time of the sensing structure.

[0013] like Figures 1 to 3 As shown, the receiving structure 811 includes a receiving body 8111 and a telescopic structure 8112, with at least one limiting part 812 disposed on the receiving body 8111. The telescopic structure 8112 is telescopically disposed on the receiving body 8111, and at least another limiting part 812 is disposed on the telescopic structure 8112. The telescopic direction of the telescopic structure 8112 is consistent with the extension direction of the pipe string 110. Thus, the telescopic movement of the telescopic structure 8112 causes the limiting part 812 disposed thereon to move toward or away from the receiving body 8111, thereby changing the size of the receiving space. This facilitates the placement of the pipe string 110 into the receiving space by workers, or ensures that the limiting part 812 can limit and stop the pipe string. Simultaneously, the telescopic direction of the telescopic structure 8112 is consistent with the extension direction of the pipe string 110 to ensure the accuracy of the pipe string length information acquired by the control module 100, thereby improving the reliability of subsequent pipe-running operations.

[0014] Specifically, when a worker or robotic arm places the tubular column 110 into the bearing space, the telescopic structure 8112 retracts towards the receiving structure 811, causing the limiting part 812 to move towards the tubular column 110 until both limiting parts 812 on both sides of the tubular column 110 are in contact with it. At this time, the control module obtains the length of the tubular column 110 based on the sensing time of the sensing structure set on the limiting part 812.

[0015] In this embodiment, the receiving component 81 further includes a first driving device, which is driven to the telescopic structure 8112 to move the limiting part 812 toward or away from the receiving body 8111. Thus, by driving the telescopic structure 8112 with the first driving device, the telescopic structure 8112 can automatically extend or retract, thereby improving the automation level of the tubing transfer equipment and the tubing lowering method, and reducing the labor intensity of workers. At the same time, the above-mentioned configuration makes the telescopic movement of the telescopic structure 8112 simpler and easier to manufacture and implement, thereby reducing the processing difficulty for workers.

[0016] Specifically, the control module 100 is electrically connected to the first drive device to control the operating parameters of the first drive device, thereby controlling the telescopic structure 8112 to automatically extend or retract.

[0017] Optionally, the first driving device is a hydraulic cylinder, a pneumatic cylinder, or a hydraulic cylinder.

[0018] In this embodiment, the limiting part 812 is a protrusion. Thus, the limiting part 812 serves to stop the end of the tubing 110. The limiting parts 812 located at both ends of the tubing 110 can clamp the tubing 110, ensuring that the receiving device 80 can drive the tubing 110 to rotate synchronously, thereby improving the receiving stability of the tubing by the receiving device 80. At the same time, the above design makes the structure of the limiting part 812 simpler, easier to manufacture and implement, thus reducing the processing difficulty for workers.

[0019] Specifically, after the length of the tube column 110 is measured, the limiting parts 812 located on both sides of the tube column 110 still abut against the tube column 110 to achieve the clamping action of the limiting parts 812 on the tube column 110, thereby preventing the tube column 110 from falling out of the receiving space and improving the load-bearing stability of the receiving device 80.

[0020] like Figures 1 to 3 As shown, there are two limiting parts 812, located at both ends of the tube column 110, respectively. Each limiting part 812 is used to limit and stop the ends of the tube column 110. There are also two sensing structures, with the two limiting parts 812 corresponding to the two sensing structures. In this way, by limiting and stopping both ends of the tube column 110 through the two limiting parts 812, the tube column 110 can be prevented from falling out of the receiving space during the rotation of the tube column 110 driven by the receiving device 80. At the same time, the above configuration makes the structure of the receiving component 81 simpler, easier to process and implement, thereby reducing the processing difficulty for workers.

[0021] In this embodiment, there are two sensing structures, and the two sensing structures are arranged in a one-to-one correspondence with the two limiting parts 812.

[0022] It should be noted that the number of limit parts 812 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the number of limit parts 812 may be four, six, eight, ten, twelve, or more.

[0023] It should be noted that the number of sensing structures is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the number of sensing structures may be four, six, eight, ten, twelve, or more.

[0024] In this embodiment, the sensing structure is a limit switch. Thus, when the limiting part 812 contacts the end of the column 110, the column 110 triggers the limit switch, causing the limit switch to send a signal to the control module 100. The control module 100 then controls the telescopic structure 8112 to stop moving, and the control module obtains the length of the column 110 based on the sensing time of the limit switch. Simultaneously, this configuration simplifies the structure of the sensing structure, making it easier to manufacture and implement, thereby reducing the processing difficulty for workers.

[0025] Specifically, the control module controls the first drive device to start and records the movement speed and start time of the first drive device. When both limit parts 812 contact the end of the column 110 and trigger the limit switch, the control module controls the first drive device to stop and records the running time of the first drive device. Then, the length of the column 110 is calculated by the mathematical model built into the control module.

[0026] like Figure 1 and Figure 4 As shown, the transfer device 90 includes a transfer body 91, a lifting structure 92, and a gripping structure 93. The transfer body 91 is rotatably mounted on the base 70. The lifting structure 92 is vertically mounted on the transfer body 91. The gripping structure 93 is mounted on the lifting structure 92 and includes a gripping part 931 for clamping the tubing column 110. Thus, on the one hand, the automatic transfer function of the tubing column 110 is achieved through the gripping structure 93 and the lifting structure 92, thereby improving the automation level of the tubing column transfer device and reducing the labor intensity of the workers; on the other hand, the gripping structure 93 can be raised and lowered via the lifting structure 92, which not only changes the gripping position of the tubing column 110 by the gripping structure 93, thus improving the gripping stability of the gripping structure 93, but also drives the tubing column 110 to rise and fall via the gripping structure 93.

[0027] Specifically, when the receiving device 80 drives the tubing string 110 to rotate to a vertical position, the lifting structure 92 drives the grabbing structure 93 to rise and fall to a suitable position to grab the tubing string 110. After the grabbing structure 93 grabs the tubing string 110, the transfer body 91 drives the lifting structure 92, the grabbing structure 93 and the tubing string 110 to rotate to the wellhead position for tubing lowering operation.

[0028] like Figure 1 and Figure 4 As shown, the gripping structure 93 includes a connecting arm 932, which is connected to the lifting structure 92. A gripping part 931 is disposed on the connecting arm 932. Alternatively, there may be one gripping part 931; or multiple gripping parts 931 may be spaced apart along the extending direction of the connecting arm 932. When there are multiple gripping parts 931, they can not only match different sizes of tubing 110, improving the versatility of the tubing transfer equipment and the tubing lowering method, but also increase the contact area between the gripping part 931 and the tubing 110, improving the gripping stability of the gripping structure 93 on the tubing 110. Simultaneously, this arrangement, on the one hand, increases the gripping space of the gripping part 931 through the connecting arm 932, enabling the gripping part 931 to grip larger sizes of tubing 110; on the other hand, it makes the selection of the number of gripping parts 931 more flexible and diverse, adapting to different working conditions and usage requirements, and also improving the processing flexibility of the operator.

[0029] In this embodiment, there are two gripping parts 931, which are spaced apart along the extension direction of the connecting arm 932. This arrangement simplifies the structure of the gripping structure 93, making it easier to manufacture and implement, thereby reducing the manufacturing difficulty for workers and the manufacturing cost of the gripping structure 93.

[0030] It should be noted that the structure of the gripping unit 931 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the gripping unit 931 may be one, three, four, or more.

[0031] In this embodiment, the two gripping parts 931 are located between the two limiting parts 812. On the one hand, this can prevent structural interference between the gripping parts 931 and the limiting parts 812. On the other hand, it allows the gripping parts 931 to hold the middle part of the tube column 110, thereby preventing the tube column 110 from shaking or even falling during the transfer process, thus improving the transfer reliability of the tube column transfer equipment and the tube lowering method.

[0032] Optionally, a pressure sensor is provided on the gripping part 931. The pressure sensor is electrically connected to the control module to detect the force between the gripping part 931 and the tubular column 110, and then feeds back the gripping status of the gripping part 931 to the control module.

[0033] In this embodiment, the tubing transfer equipment and tubing lowering method further includes a second driving device, which is driven by the receiving device 80 to drive the receiving device 80 to rotate the tubing 110. Thus, the aforementioned configuration of the second driving device enables the automatic rotation of the receiving device 80, thereby improving the automation level of the tubing transfer equipment and tubing lowering method and reducing the labor intensity of workers.

[0034] Specifically, the control module 110 is electrically connected to the second drive device to control the operating parameters of the second drive device. After the gripping part 931 grips the tube column 110, the control module controls 110 to start the second drive device to drive the receiving device 80 to rotate.

[0035] Optionally, the lifting structure 92 can be a hydraulic cylinder, a pneumatic cylinder, or a hydraulic cylinder. This design simplifies the structure of the lifting structure 92, making it easier to manufacture and implement, thus reducing the processing difficulty and cost for workers. Furthermore, it allows for more flexible and diverse selection of the type of lifting structure 92 to adapt to different working conditions and usage requirements, thereby increasing the processing flexibility for workers.

[0036] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0037] The receiving device of the pipe transfer equipment and pipe lowering method is rotatably mounted on a machine base. The receiving component of the receiving device includes a receiving structure and at least two limiting parts disposed on the receiving structure. The at least two limiting parts are arranged opposite each other and surround the receiving structure to form a receiving space for receiving the pipe. At least one limiting part can move toward or away from the other limiting part to adjust the size of the receiving space, facilitating the placement of the pipe into the receiving space by the operator. Each limiting part is provided with at least one sensing structure connected to a control module. When the sensing structures on at least two limiting parts detect the pipe, the control module obtains the length of the pipe based on the sensing time of the sensing structures. The transfer device is mounted on the machine base. Thus, after the receiving device receives the pipe, the receiving space is adjusted until all the limiting parts are in contact with the pipe, allowing for the measurement of the pipe length and adjustment of the parameters for the pipe lowering operation. After measuring the length of the tubing, the receiving device rotates the tubing relative to the base to transport it to the location of the transfer device. The transfer device then moves the tubing to a preset position, facilitating pipe lowering operations. This solves the problem of low efficiency in tubing handling and transfer in existing technologies and reduces the labor intensity of workers. Furthermore, the tubing length information obtained by the control module facilitates subsequent pipe lowering operations, thereby improving the reliability of these operations.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and concept of the present invention, should be covered within the scope of protection of the present invention.
