Description

Technical Field

[0001] This utility model relates to the technical field of cementing engineering, and in particular to a measuring device. Background Technology

[0002] Cement stone porosity parameters are crucial for cementing design, and accurately obtaining these parameters is fundamental to ensuring the long-term sealing of the cement sheath. Current technologies utilize porosity mechanics experimental setups to acquire porosity parameters of cement stone under different temperature and pressure conditions, providing data support for evaluating the long-term sealing integrity of the cement sheath and optimizing the mechanical properties of the cement slurry.

[0003] Currently, the GDS-LF50 pore mechanics experimental device is the main instrument capable of measuring the pore force parameters of cement stone. However, this device has certain errors in the accuracy of the pore force parameters during measurement, and therefore cannot effectively reflect the true performance of the cement stone. Utility Model Content

[0004] The purpose of this invention is to improve the problem of measurement accuracy errors in existing measuring devices when measuring the pore force of cement stone, and to provide a measuring device.

[0005] The technical solutions for achieving the above objectives include the following:

[0006] The measuring device includes: a base, a drive assembly, a limiting member, a support frame, and a clamping measuring assembly. The drive assembly is mounted on the base, a first end of the support frame is fixed to the base, and the limiting member is mounted on a second end of the support frame. A test station is provided between the limiting member and the drive assembly.

[0007] The clamping and measuring assembly includes a measuring element and a clamping element. The first end of the clamping element is mounted on the output end of the driving assembly, the first end of the measuring element is mounted on the second end of the clamping element, and the second end of the measuring element is mounted on a support frame.

[0008] In one embodiment, the clamping member includes a fastener and two clamping rings, each clamping ring having a clamping end, the two clamping ends being disposed opposite each other to form a clamping position, the driving component being at least partially disposed within the clamping position, and the two clamping rings being fixed together by the fastener.

[0009] In one embodiment, the measuring elements are in two sets, each of the clamping rings has a support end, and the two sets of measuring elements are respectively installed on the support ends of the two clamping rings.

[0010] In one embodiment, each clamping ring includes a first connecting portion and a second connecting portion, both of which are bent.

[0011] The first end of the first connecting part is a clamping end, the second end of the first connecting part is fixed to the first end of the second connecting part, and the second end of the second connecting part is a supporting end.

[0012] In one embodiment, each of the measuring elements includes a sensing element and a sliding rod. The first end of the sensing element is mounted on a support frame, the first end of the sliding rod is mounted on a support end, and the second end of the sliding rod is slidably engaged with the second end of the sensing element.

[0013] The sensor is used to measure the distance the sliding rod moves.

[0014] In one embodiment, the support end has a limiting groove, and the first end of the sliding rod is disposed in the limiting groove.

[0015] In one embodiment, each clamping ring has ribs at both ends, and the ribs have mounting holes, wherein the ribs of one clamping ring correspond to the ribs of the other clamping ring; the mounting holes of the two ribs are for fasteners to pass through, so that the corresponding two ribs are fixed together by fasteners.

[0016] In one embodiment, the driving assembly includes a driving member and a driving part, the driving member is mounted on a base, the driving part is mounted on the output end of the driving member, and the clamping member is mounted on the driving part.

[0017] In one embodiment, the clamping member is mounted on the top of the drive unit and positioned close to the test station.

[0018] In one embodiment, the drive element includes a hydraulic cylinder or an electric actuator.

[0019] The technical solution provided by this utility model has the following advantages and effects:

[0020] When the sample under test is subjected to a force by the driving component, it undergoes compressive deformation. The output end of the driving component moves upward, driving the clamping component to move upward as well. During the movement of the clamping component, the measured component senses and detects the distance the clamping component moves upward. This upward distance is the deformation of the sample under test. By placing the clamping component at the output end of the driving component, the distance between the clamping component and the sample under test is relatively close, making the testing method more direct. The movement variable of the clamping component directly reflects the variable of the sample under test, effectively improving the measurement error and solving the problem of certain measurement accuracy errors in the existing measuring devices when measuring the pore force of cement stone.

[0028] To facilitate understanding of this utility model, the specific embodiments of this utility model will be described in more detail below with reference to the accompanying drawings.

[0029] Unless otherwise specified or defined, the terms "first," "second," etc., used in this document are for distinguishing names only and do not represent a specific number or order.

[0030] Unless otherwise stated or defined, the term “and / or” as used herein includes any and all combinations of one or more of the associated listed items.

[0031] It should be noted that when a component is considered "fixed" to another component, it can be directly fixed to the other component or there can be an intervening component; when a component is considered "connected" to another component, it can be directly connected to the other component or there can be an intervening component; when a component is considered "mounted" on another component, it can be directly mounted on the other component or there can be an intervening component; when a component is considered "placed" on another component, it can be directly placed on the other component or there can be an intervening component.

[0032] This utility model proposes a measuring device 100, such as... Figures 1 to 3 As shown, the device includes a base 11, a drive assembly 1, a limiting member 3, a support frame 31, and a clamping and measuring assembly 4. The drive assembly 1 is mounted on the base 11. The first end of the support frame 31 is fixed to the base 11. The limiting member 3 is mounted on the second end of the support frame 31. A test station 21 is provided between the limiting member 3 and the drive assembly 1. The clamping and measuring assembly 4 includes a measuring member 41 and a clamping member 42. The first end of the clamping member 42 is mounted on the output end of the drive assembly 1. The first end of the measuring member 41 is mounted on the second end of the clamping member 42. The second end of the measuring member 41 is mounted on the support frame 31.

[0033] Specifically, test station 21 is used to place the sample to be tested 2. The bottom of the sample to be tested 2 is located on the output end of the drive component 1, and the top of the sample to be tested 2 abuts against the limiting member 3. The drive component 1 is used to apply force to the sample to be tested 2, and the measuring member 41 is used to test the movement distance of the output end of the drive component 1, thereby testing the deformation of the sample to be tested 2, and then calculating the porosity of the sample to be tested 2 through a calculation formula. The clamping member 42 is used to be installed on the output end of the drive component 1. The clamping member 42 is relatively close to the lower end of the sample to be tested 2, and the limiting member 3 is made of metal, which has a high density and hardness, and the deformation can be ignored.

[0034] When the sample 2 to be tested is subjected to a force by the driving component 1, the sample 2 to be tested undergoes compression deformation. The output end of the driving component 1 moves upward, driving the clamping member 42 to move upward. During the movement of the clamping member 42, the measuring component 41 senses and detects it. The measuring component 41 detects the distance that the clamping member 42 moves upward, and the distance that the clamping member 42 moves upward is the deformation amount of the sample 2 to be tested. By setting the clamping member 42 at the output end of the driving component 1, the distance between the clamping member 42 and the sample 2 to be tested is relatively close, and the testing method is more direct. The movement variable of the clamping member 42 directly reflects the variable of the sample 2 to be tested, and its measurement error is effectively improved. It also solves the problem that the measurement accuracy of the existing measuring device 100 has a certain error in the process of measuring the pore force of cement stone.

[0035] Preferably, the driving assembly 1 includes a driving member 12 and a driving part 13. The driving member 12 is mounted on the base 11, the driving part 13 is mounted on the output end of the driving member 12, and the clamping member 42 is mounted on the driving part 13. Specifically, the driving member 12 is fixed on the base 11, and the output end of the driving member 12 is used to drive the driving part 13 to move. When the driving part 13 drives the sample 2 to be tested to deform, it drives the clamping member 42 to move upward, so that the measuring member 41 measures the amount of deformation of the sample 2 to be tested.

[0036] Preferably, the clamping member 42 is mounted on the top of the drive unit 13 and positioned close to the test station 21. Specifically, when the drive unit 13 contacts the sample 2 to be tested, the drive unit 13 applies a pushing force to the sample 2, and the sample 2 generates a reaction force to the drive unit 13, causing the drive unit 13 to undergo slight deformation. By mounting the clamping member 42 on the top of the drive unit 13 and positioning it close to the test station 21, the variables of the sample 2 to be tested can be directly measured. If the clamping member 42 is mounted on the bottom and middle of the drive unit 13, it will incorporate some of the variables of the drive unit 13 when it moves. Therefore, positioning the clamping member 42 on the top of the drive unit 13 can further reduce measurement errors.

[0037] Preferably, the clamping member 42 includes a fastener 423 and two clamping rings 421, each clamping ring 421 having a clamping end 4251. The two clamping ends 4251 are arranged opposite each other to form a clamping position. The driving component 1 is at least partially disposed within the clamping position, and the two clamping rings 421 are fixed together by the fastener 423. Specifically, the inner wall of each clamping ring 421 is used to fit against the output end of the driving component 1, so that the driving component 1 is at least partially located within the clamping position. The two clamping rings 421 are fixed together by the fastener 423. When the output end of the driving component 1 moves upward, it drives the clamping rings 421 to move, thereby allowing the measuring member 41 to measure the movement of the clamping rings 421.

[0038] Preferably, there are two sets of measuring elements 41, each clamping ring 421 having a support end 4261, and the two sets of measuring elements 41 are respectively installed on the support ends 4261 of the two clamping rings 421. Specifically, when the deformation at the left and right ends of the sample 2 under test produces a certain error, one measuring element 41 is used to test the movement variable of one clamping ring 421, and the other measuring element 41 is used to test the movement variable of the other clamping ring 421. In this way, the deformation at different positions of the sample 2 under test can be accurately calculated.

[0039] Preferably, each clamping ring 421 includes a first connecting portion 425 and a second connecting portion 426, both of which are bent. The first end of the first connecting portion 425 is the clamping end 4251, the second end of the first connecting portion 425 is fixed to the first end of the second connecting portion 426, and the second end of the second connecting portion 426 is the supporting end 4261. Specifically, by setting both the first connecting portion 425 and the second connecting portion 426 to be bent, and by making the first connecting portion 425 and the second connecting portion 426 an integral structure, a certain gap can be provided between the clamping ring 421 and the drive assembly 1 and the base 11, avoiding contact between the clamping ring 421 and the outer wall of the drive assembly 1 and the upper end of the base 11. In this way, when the clamping ring 421 moves, the surrounding environment cannot affect the slight movement of the clamping ring 421, further improving the testing accuracy of the measuring component 41.

[0040] Preferably, each measuring element 41 includes a sensing element 411 and a sliding rod 412. The first end of the sensing element 411 is mounted on the support frame 31, and the first end of the sliding rod 412 is mounted on the support end 4261. The second end of the sliding rod 412 is slidably engaged with the second end of the sensing element 411. The sensing element 411 is used to measure the moving distance of the sliding rod 412. Specifically, the bottom of the sliding rod 412 is mounted on the support end 4261 of the clamping ring 421, and the top of the sliding rod 412 is slidably engaged with the sensing element 411. When the clamping ring 421 moves, the clamping ring 421 drives the sliding rod 412 to move upward, causing the sliding rod 412 to undergo a displacement change relative to the sensing element 411. The sensing element 411 is used to sense the minute changes in the sliding rod 412, and the deformation of the sample 2 under test is measured by the moving distance of the sliding rod 412.

[0041] Preferably, the support end 4261 has a limiting groove 424, and the first end of the sliding rod 412 is disposed in the limiting groove 424. The limiting groove 424 restricts the movement of the first end of the sliding rod 412; simultaneously, the clamping ring 421 can be detachably connected to the sliding rod 412, facilitating the transportation and assembly of the measuring component 4.

[0042] Preferably, each clamping ring 421 has ribs 422 at both ends, and the ribs 422 have mounting holes 4221, wherein the ribs 422 of one clamping ring 421 correspond to the ribs 422 of the other clamping ring 421; the mounting holes 4221 of the two ribs 422 allow fasteners 423 to pass through, so that the corresponding two ribs 422 are fixed together by the fasteners 423. Specifically, by providing ribs 422 at both ends of the clamping rings 421, each clamping ring 421 has two ribs 422, and the two ends of the clamping rings 421 are fixed by two sets of corresponding ribs 422, so that both ends of the two clamping rings 421 are fixed by the fasteners 423, thereby improving the stability of the two clamping rings 421 after connection.

[0043] Preferably, the drive component 12 includes a hydraulic cylinder or an electric actuator. A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy, performing linear reciprocating motion (or oscillating motion). It has a simple structure and reliable operation. When used to achieve reciprocating motion, a reduction gear is unnecessary, and there is no transmission backlash, resulting in smooth movement. An electric actuator is an electric drive device that converts the rotational motion of an electric motor into the linear reciprocating motion of a actuator. It can be used as an actuator in various simple or complex processes to achieve remote control, centralized control, or automatic control. In this embodiment, the drive component 12 is preferably a hydraulic cylinder.
