Description

Technical Field

[0001] This utility model relates to the field of clamp performance testing technology, and in particular to an axial force measuring device for a T-groove clamp. Background Technology

[0002] In pipeline systems of the oil and chemical industry, T-groove clamps are used to connect pipeline components. They need to withstand various forces, including the pressure of the medium inside the pipeline and the loads from the external environment. Accurately measuring the axial force on the clamps helps to assess the reliability of the connection, prevent loosening and leakage, and ensure the safe and stable operation of the pipeline system. In oil pipelines, clamps need to withstand the pressure of high-pressure oil inside the pipeline. Measuring the axial force can ensure that the clamps can effectively tighten the pipeline and prevent leakage.

[0003] A search revealed Chinese Patent Publication No. CN216694711U, which discloses a clamp shape inspection device, relating to the field of clamp inspection. The device includes two first support plates and a second support plate fixedly installed on one side of the two first support plates close to each other. A first measuring component penetrating the second support plate and a second measuring component connected to the first measuring component are installed at the bottom of the second support plate. In this experiment, the clamp is engaged with a first limiting block. The clamp mounting hole is pressed and limited by the smooth surface at the top of the measuring block, causing the measuring block to move. The lateral offset dimension of the mounting hole can be read through a second observation hole. When the clamp is removed... Under the elastic force of the second spring, the first limiting sleeve drives the measuring block to reset, which facilitates the measuring block to cooperate with the clamp to be measured, improves the stability of the measurement results, and has a small deviation from the actual size of the clamp. The detection efficiency and reliability of the detection results are high, and the efficiency of clamp shape inspection is improved. However, the above solution cannot truly reflect the axial force of the clamp under actual working conditions. There is a lack of a special device for measuring the axial force of T-groove clamps, which cannot meet the needs for accurate measurement of clamp axial force. Some existing general mechanical measuring devices cannot well adapt to the structural characteristics and measurement requirements of T-groove clamps and cannot meet the user's needs.

[0004] Therefore, this utility model proposes an axial force measuring device for T-groove clamps to address the shortcomings of existing technologies. Utility Model Content

[0005] In view of the problems in the existing technology of axial force measuring device for T-groove clamps, such as the external wiring of the sensor data line being easily interfered with, affecting the measurement accuracy, and the low integration of the overall structure, this utility model aims to provide an axial force measuring device for T-groove clamps with an improved structure that can effectively solve the above problems.

[0006] This utility model provides an axial force measuring device for a T-groove clamp, comprising: a base, a loading housing, a mounting plate, a pressure sensor, a cover plate; and fixing screws and a data cable.

[0007] The base and the fixing screw are coaxially connected by a unique circular opening, which is the key to realizing the function of this solution.

[0008] Furthermore, the loading housing is fixedly connected to the top of the base, the mounting plate is disposed inside the loading housing, the pressure sensor is mounted on the top of the mounting plate, and the cover plate is vertically movable above the pressure sensor and keeps in contact with it. The routing of the data cable connected to the pressure sensor is a clever feature of this solution. After passing through the mounting plate, the data cable passes directly through the circular opening located at the center of the base and the fixing screw, and is led out from the bottom of the base, so that the transmission path of the data cable is completely separated from the force measurement area at the top in space.

[0009] Preferably, in order to ensure the stability of the mounting plate's movement under pressure, the mounting plate is slidably connected to the inner wall of the loading housing through multiple guide posts. The structure limits the mounting plate to move smoothly only in the vertical direction, avoiding errors caused by deflection during the measurement process.

[0010] Preferably, a support block is fixed to the bottom of the loading housing, and the support block is set on the top of the base. Furthermore, the support block and the base are connected by multiple support columns, thereby forming an accommodating space between them. The space not only enhances the support strength of the overall structure, but also provides sufficient buffer and routing area for the data cable led out from the center.

[0011] Preferably, the top outer wall of the cover plate is used for detachably installing the clamp ring to be measured. Specifically, the clamp ring is locked and fixed by a long screw and a bolt tightened on the outer wall of the long screw. This method can conveniently and quickly clamp and replace clamp rings of different specifications.

[0012] Preferably, in order to buffer the impact and make the pressure transmission more uniform, a soft pad is provided on the bottom surface of the cover plate at the position corresponding to the pressure sensor. The soft pad can effectively absorb the instantaneous impact force, protect the sensor and improve the repeatability of the measurement.

[0013] Preferably, in order to simplify internal wiring and improve the reliability of signal transmission, the mounting plate is also integrated with a transmission port. The signal output terminals of multiple pressure sensors are electrically connected to the data line through the transmission port, realizing centralized management and unified output of signals, which facilitates subsequent maintenance and repair.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, when the top is pressed during testing, multiple pressure sensors at the bottom of the cover plate can simultaneously capture pressure data and quickly transmit it to the user panel via a data cable. The operation process is simple and direct. In addition, the data cable passes through the middle of the fixing screw, avoiding interference from the line to the axial force measurement. This not only ensures the accuracy of the test data but also greatly reduces the difficulty of operation for users, achieving an efficient and convenient testing experience.

[0016] 2. This utility model, through the cooperation of long screws and bolts, can firmly fix the clamp ring to the top of the cover plate, effectively preventing the parts from falling off during the measurement process. At the same time, the mounting plate is precisely assembled in the loading shell with the help of the guide column. Combined with the hierarchical fixing structure of the bearing block and the base, it not only ensures the installation stability of the overall device, but also provides a solid and reliable structural foundation for subsequent axial force detection, reducing measurement errors caused by loose parts.

[0017] 3. This utility model solves the problem of uneven force distribution caused by the tilting of the mounting plate carrying the sensor when pressure is applied by setting guide columns to guide the movement of the mounting plate. It achieves the technical effect of ensuring that the cover plate can stably transmit pressure to the pressure sensor below in the vertical direction when under pressure, thereby ensuring the accuracy of force value acquisition.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example:

[0027] Please refer to Figures 1 to 5 This utility model provides an axial force measuring device for a T-groove clamp, which aims to solve the technical problem that the data sensing circuit of the existing measuring device is set externally, which is prone to interference with the force-bearing component during testing, affecting the stability and accuracy of the measurement.

[0028] like Figure 1 , Figure 2 and Figure 5 As shown, an axial force measuring device for a T-groove clamp includes a base 14 and a loading housing 2 fixedly connected to the top of the base 14. The base 14 is used to stably mount the entire device on the workbench surface, and the loading housing 2 is used to accommodate the internal measuring components. The structure of the device lies in the design of its signal transmission path. In order to achieve interference-free transmission of the measurement signal, the device includes a fixing screw 15 for locking the base 14 to the workbench, and a circular opening 16 is coaxially and through the center of the base 14 and the fixing screw 15.

[0029] Inside the device, a pressure sensor 5 for sensing pressure is connected to a data cable 7. After the data cable 7 is led out from the pressure sensor 5, it passes directly downward through the circular opening 16 and finally extends from the bottom of the base 14 to connect to an external data processing device. This structure, which leads the data cable 7 out from the center of the device, completely isolates the routing path of the data cable 7 from the cover plate 8 on the top of the device used for applying pressure for measurement. During the measurement process by pressing the cover plate 8, the data cable 7 will not be displaced or squeezed by external forces, thus ensuring the stability of the process of converting mechanical signals into electrical signals and the accuracy of the final measurement results. To achieve accurate axial force measurement, the axial force measuring device of the T-groove clamp is provided with a mounting plate 4 inside the loading housing 2. The upper surface of the mounting plate 4 is used to mount the pressure sensor 5.

[0030] Please refer to Figure 2 and Figure 3 The mounting plate 4 is a roughly circular plate structure with a flat top surface for fixing and supporting multiple pressure sensors 5. The mounting plate 4 is slidably connected to the inner wall of the loading housing 2 through multiple vertically arranged guide columns 3. This structure ensures that when the mounting plate 4 is subjected to pressure from above, it can only move steadily downward in the vertical direction without tilting or shaking. The bottom of the loading housing 2 is also fixedly connected to a support block 1. The top surface of the support block 1 is used to support and hold the mounting plate 4. At the same time, the bottom of the support block 1 is fixedly connected to the base 14 through multiple support columns 13, so that a receiving space is formed between the support block 1 and the base 14. The receiving space provides a buffer and routing area for the data cable 7 led out from the bottom.

[0031] Please refer to Figure 3 and Figure 4 The top outer wall of the cover plate 8 of the device is used to detachably install the clamp ring 9 to be measured. The specific installation and fixing structure includes a long screw 11 and a bolt 12 that can be tightened to the outer wall of the long screw 11. By operating the bolt 12 to move along the axial direction of the long screw 11, the clamp ring 9 can be fastened to the predetermined position of the cover plate 8. In order to ensure that the pressure transmitted from the cover plate 8 to the pressure sensor 5 is uniform and has a certain buffer, a soft pad 10 is also fixedly installed on the bottom surface of the cover plate 8, corresponding to the position of the pressure sensor 5. In order to make the internal signal transmission line more orderly and reliable, a transmission port 6 is also integrated on the mounting plate 4. The signal output ends of multiple pressure sensors 5 are first collected and electrically connected to the transmission port 6, and then the transmission port 6 is uniformly connected to the data line 7 to achieve electrical connection, thereby simplifying the internal wiring.

[0032] Working principle: The clamp ring 9 is placed on the top of the cover plate 8. By rotating the bolt 12 on the outer wall of the long screw 11, the clamp ring 9 is fixed to the top outer wall of the cover plate 8 and will not easily fall off. When axial force needs to be measured, the top is pressed. After the top is subjected to pressure, multiple pressure sensors 5 at the bottom of the cover plate 8 detect it and transmit the detection data to the user panel via the data cable 7. The pressure sensors 5 are installed on the top of the mounting plate 4. The bottom of the mounting plate 4 is fixed to the inner wall of the loading housing 2 and installed through the guide post 3. It is placed on the top of the bearing block 1. The bottom fixed base 14 is installed on the worktable by fixing screws 15. The fixing screws 15 have an opening in the middle, through which the data cable 7 passes without interfering with the axial force measurement at the top. This detection method is convenient and fast, and easy for users to operate.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
