Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to enable readers to better understand this utility model. However, the technical solutions claimed by this utility model can be implemented even without these technical details and with various changes and modifications based on the following embodiments.

[0020] To facilitate understanding of the embodiments of this application, the relevant content regarding the measurement of the inner diameter of the sleeve hanger will be introduced first.

[0021] As oil exploration and development advances into deeper and more complex formations, the requirements for the precision and reliability of oil drilling equipment are increasing. Casing clamps are key tools for running in and out of casing during drilling operations, and different sizes of casing clamps are often needed on-site, requiring quick identification of the model for accurate use.

[0022] In existing technologies, the differentiation of casing hanger models typically involves measuring the inner diameter using conventional measuring tools such as tape measures or calipers, and then reading the scale on the tape measure or calipers to make the distinction. However, the complex environment at construction sites and the obstruction of vision when manually reading the scale make it difficult to quickly distinguish the dimensions of the casing hangers. Furthermore, the dimensions corresponding to different models of casing hangers are fixed. When switching between different casing hangers for measurement, measuring tools such as tape measures or calipers with fine scales need to be re-unlocked from the zero scale, which is cumbersome and affects work efficiency.

[0023] Example 1: The present invention relates to a device for measuring the inner diameter of a sleeve hanger.

[0024] Compared with the prior art, the present invention involves placing the main measuring scale and the auxiliary measuring scale against the inner diameter sides of the sleeve hanger, so that the auxiliary measuring scale is aligned with one of the sensing modules of the main measuring scale. This causes the sensing element on the auxiliary measuring scale to generate a voltage signal with the sensing module, enabling the voice broadcast module to announce the inner diameter size corresponding to the current sensing module. This facilitates the identification of the inner diameter of the current sleeve hanger. By repeatedly analyzing each sleeve hanger, the dimensions of each sleeve hanger can be accurately and quickly distinguished, improving the convenience of operation and work efficiency.

[0025] The following is a detailed description of the implementation details of the casing hanger inner diameter measuring device in this embodiment. The following content is only for the convenience of understanding and is not necessary for implementing this solution.

[0026] The present invention provides a device for measuring the inner diameter of a sleeve hanger, such as... Figure 1 and Figure 2 As shown, it includes: a main measuring scale 1, a secondary measuring scale 2, a voice broadcast module 3, a sensor 5, and at least two sensing modules 4. Among them: The voice broadcast module 3 is installed on the main measuring scale 1; each sensing module 4 is arranged on the main measuring scale 1 along the sliding direction of the secondary measuring scale 2, and the arrangement distance of each sensing module 4 corresponds to the sleeve hanger with different inner diameters; the secondary measuring scale 2 is slidably mounted on the main measuring scale 1 in a straight line; the sensing element 5 is installed on the secondary measuring scale 2 to move synchronously with the movement of the secondary measuring scale 2; when the sensing element 5 slides to the same position as any sensing module 4, the corresponding sensing module 4 generates a voltage signal and transmits it to the voice broadcast module 3 to feed back the corresponding inner diameter information to the voice broadcast module 3 for voice playback.

[0027] Specifically, the main measuring scale 1 is equipped with several indicator lights 6. The number of indicator lights 6 corresponds to the number of sensing modules 4, and each indicator light 6 is arranged at the position of each sensing module 4 and connected to the sensing module 4. When one of the sensing modules 4 generates a voltage signal, the corresponding indicator light 6 is lit. Through the configuration of each indicator light 6, when the measuring scale 2 moves to the position where the sensing element 5 is aligned with a certain sensing module 4, not only can the relevant information be broadcast through the voice broadcast module 3, but the indicator light 6 corresponding to the aligned sensing module 4 can also be lit, allowing the operator to directly know the inner diameter of the sleeve hanger through the indicator light 6.

[0028] Furthermore, the main measuring scale 1 is provided with scale lines along the sliding direction of the secondary measuring scale 2. When measuring the inner diameter of the sleeve hanger by measuring the secondary measuring scale 2, the specific inner diameter can be read directly through the scale line where the secondary measuring scale 2 stops. In conjunction with the illumination and position of the indicator light 6, it is convenient for the user to quickly obtain the currently measured inner diameter of the sleeve hanger.

[0029] Specifically, indicator light 6 is located on the front of the main measuring scale 1, and sensor module 4 is located on the back of the main measuring scale 1; sensor 5 is located on the side of the auxiliary measuring scale 2 facing the back of the main measuring scale 1. During measurement, the main measuring scale 1 can be placed face up on the sleeve hanger. By sliding the auxiliary measuring scale 2, the sensor 5 on the back of the auxiliary measuring scale 2 moves until the auxiliary measuring scale 2 touches the inner wall of the sleeve hanger, thus quickly detecting the inner diameter of the sleeve hanger. Indicator light 6 illuminates directly on the front for easy viewing by the user. Correspondingly, in this embodiment, the scale lines are also located on the front of the main measuring scale 1 for easy reading in conjunction with indicator light 6.

[0030] In some embodiments, such as Figure 3 As shown, one end of the main measuring scale 1 is provided with a first measuring part 12 for contacting the inner wall of the sleeve hanger, and the secondary measuring scale 2 is provided with a second measuring part 21 for contacting the inner wall of the sleeve hanger; the first measuring part 12 and the second measuring part 21 are arranged opposite to each other in their extending directions. By cooperating with the first measuring part 12 and the second measuring part 21, they can be conveniently pressed against the two sides of the inner wall of the sleeve hanger, thereby cooperating with the sensing element 5 and the sensing module 4 to quickly detect the inner diameter of each sleeve hanger and distinguish sleeve hangers with different inner diameters.

[0031] Specifically, the first measuring part 12 is positioned at the zero point of the scale line of the measuring main scale 1. By contacting the first measuring part 12 against one side of the inner wall of the sleeve hanger, the measuring auxiliary scale 2 can be slid directly until the second measuring part 21 on the measuring auxiliary scale 2 contacts the other side of the inner wall of the sleeve hanger, which facilitates quick detection of the inner diameter of the sleeve hanger.

[0032] Furthermore, the first measuring part 12 includes a first extension 121 and a first contact part 122; the first extension 121 is vertically disposed on the back of the main measuring scale 1; the first contact part 122 is disposed at the bottom end of the first extension 121 to contact the inner wall of the sleeve hanger; the second measuring part 21 includes a second extension 211 and a second contact part 212; the second extension 211 is vertically disposed on the back of the auxiliary measuring scale 2; the second contact part 212 is disposed at the bottom end of the second extension 211 to contact the inner wall of the sleeve hanger. By arranging the first measuring part 12 and the second measuring part 21 on the back of the main measuring scale 1 and the auxiliary measuring scale 2, the first measuring part 12 and the second measuring part 21 can be directly inserted into the sleeve hanger during the measurement process. Furthermore, by taking advantage of the length of the main measuring scale 1, the measuring device can be directly mounted on the sleeve hanger. By moving the main measuring scale 1 so that the first measuring part 12 abuts against the inner wall of one side of the sleeve hanger, the inner diameter of the sleeve hanger can be directly measured by sliding the auxiliary measuring scale 2, thus improving the convenience of operation and use.

[0033] To facilitate measurement, damping pads 8 are provided at the ends of both the first contact portion 122 and the second contact portion 212, so that they have a certain frictional resistance when they abut against the inner wall of the sleeve, preventing easy slippage and improving the accuracy and convenience of measurement.

[0034] In some embodiments, such as Figure 1 and Figure 2 As shown, the main measuring scale 1 extends in a straight line; the auxiliary measuring scale 2 is fitted onto the main measuring scale 1 and slides on both sides, forming actuating ends 22. This allows the auxiliary measuring scale 2 to be moved directly by actuating ends 22 after the main measuring scale 1 is placed on the sleeve hanger. Both the front and back of the auxiliary measuring scale 2 can be actuated, making it convenient for users to operate and improving the ease of measurement.

[0035] In some embodiments, a base 11 is provided at one end of the measuring scale 1; the voice broadcast module 3 is mounted on the base 11, and a power module 7 for power supply is provided on the base 11. The power module 7 is electrically connected to the voice broadcast module 3 and each of the sensing modules 4. Specifically, the power module 7 can be configured with a rechargeable battery or a removable battery, and a disassembly port is provided on the base 11 for the power module 7 to be disassembled and installed, facilitating long-term use.

[0036] Furthermore, a microcontroller is installed within the base 11 to process the signals from the sensing module 4 and control the voice broadcast module 3 and indicator light 6 to turn on and off. Simultaneously, a power switch 9 is installed on the base 11 to control the opening and closing of the measuring device. In this embodiment, both the microcontroller and the power switch 9 are connected to the power module 7. The power switch 9 is located between the power module 7 and the microcontroller, used to connect or disconnect the power supply line between the power module 7 and the microcontroller, thereby controlling the opening and closing of the measuring device.

[0037] In some embodiments, the sensing module 4 includes a Hall sensor and the sensing element 5 includes an electromagnet. Through the electromagnetic cooperation between the Hall sensor and the electromagnet, the Hall sensor can generate a signal when it is aligned with the electromagnet, thereby improving the detection efficiency.

[0038] Specifically, the electromagnet is cylindrical, with its height direction perpendicular to the measuring main scale 1 and extending towards the sensing module 4, which facilitates the rapid generation of signals by the electromagnet after it is located behind the sensing module 4, thereby improving detection efficiency.

[0039] Furthermore, the microcontroller is an STC89C2051, the voice broadcast module 3 is an HX6320, and the sensing module 4 has 6 sensors, each equipped with a Hall effect chip A3144E. When measuring the sleeve clamp, the measuring surfaces at the first contact part 122 and the second contact part 212 of the measuring main scale 1 and the measuring auxiliary scale 2 contact the inner wall of the clamp. The electromagnet of the auxiliary scale approaches the Hall effect chip (AE144E), and the OUT pin is at a high potential, illuminating the corresponding indicator light 6. The STC89C2051 microcontroller reads the potential of the pins, and the voice chip XH6320 determines the potential of a certain pin. If the potential of a certain pin is high, the chip broadcasts the sleeve size (pre-recorded in the internal audio file) through the speaker.

[0040] The casing hanger inner diameter measuring device provided in this embodiment uses a first measuring part 12 of the main measuring scale 1 and a second measuring part 21 of the auxiliary measuring scale 2 to abut against both sides of the inner diameter of the casing hanger. This allows the auxiliary measuring scale 2 to be aligned with one of the sensing modules 4 of the main measuring scale 1. Consequently, the sensing element 5 on the auxiliary measuring scale 2 and the sensing module 4 generate a voltage signal, enabling the voice broadcast module 3 to broadcast the inner diameter dimension corresponding to the current sensing module 4. This facilitates the identification of the inner diameter of the casing hanger and allows for quick determination of the inner diameter of the casing hanger even in noisy environments. By repeatedly analyzing each casing hanger, the device can accurately and quickly distinguish the dimensions of each casing hanger, improving ease of operation and work efficiency.

However, if other terms can achieve the same purpose, they can be replaced by other expressions.

[0042] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention. In practical applications, the technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
