Description

Technical Field

[0001] This invention relates to the field of testing machine technology, and in particular to a measurement system and method for a horizontal anchor bolt testing machine. Background Technology

[0002] Tensile testing and relaxation testing are the most common testing methods for material mechanical property testing and play an important role in material performance testing. Testing machines are essential testing equipment for completing material mechanical property tests.

[0003] Currently, the most common tensile and relaxation testing machines are vertical testing machines. The specimens are typically made by cutting a portion from the workpiece to be tested, for example, cutting a section of the workpiece about 2-3 meters long. These vertical testing machines usually have the measuring device for measuring the deformation of the specimen fixed to the machine body. However, when it is necessary to perform performance testing on a longer specimen (such as 10 meters or 20 meters), these vertical testing machines, due to their own structural limitations or the limitations of the testing site, often cannot perform high-precision testing on longer specimens. Furthermore, during the loading process on the specimen, if the load is large, the machine body may deform under the influence of the loading force, which in turn affects the measurement accuracy of the measuring device within the testing machine.

[0004] Based on this, existing technology provides a horizontal testing machine capable of testing specimens of different sizes, which improves the testing range and measurement accuracy of the machine to some extent. However, the horizontal testing machine provided by the prior art still directly fixes the measuring device to the machine body, thus failing to solve the problem of the measuring device being affected by the loading force of the testing machine itself, as seen in the aforementioned vertical testing machine. Furthermore, no literature in the field of testing machine technology has been found that pays sufficient attention to this aspect.

[0005] This shows that existing technologies need further improvement and enhancement. Summary of the Invention

[0006] This application provides a measurement system and method for a horizontal anchor bolt testing machine to solve at least one of the above-mentioned technical problems.

[0007] In a first aspect, this application provides a measuring system for a horizontal anchor bolt testing machine, which includes a body with a loading device and a measuring device disposed below the body;

[0008] The loading device includes a loading assembly for clamping the anchor rod and a first driving member connected to the loading assembly. Under the driving action of the first driving member, the loading assembly can stretch the anchor rod in the horizontal direction.

[0009] The measuring device includes a support frame and a measuring component located above the support frame, as well as a second driving member connected to the support frame and the measuring component respectively, the second driving member being capable of driving the measuring component to contact or separate from the end face of the anchor rod;

[0010] The loading component has a cavity with a bottom opening, the measuring component is at least partially located in the cavity, and the measuring device does not contact the body, so as to reduce the interference of the loading device on the measuring device during the loading process.

[0011] The measuring system for the horizontal anchor bolt testing machine in this application also has the following additional technical features:

[0012] The support frame includes a support plate and legs located below the support plate; the measuring device also includes a connecting plate and a fixing block disposed on the support plate, the second driving member is disposed at the top of the fixing block, and the second driving member is connected to the measuring component through the connecting plate.

[0013] The side wall of the loading component is provided with an installation groove for accommodating the anchor rod, and the installation groove is connected to the cavity; the loading device also includes an anti-detachment component sleeved on the end of the anchor rod, which can abut against the inner wall of the cavity to prevent the anchor rod from coming out of the installation groove during loading.

[0014] The loading device further includes a crash plate fixed to the top wall of the loading assembly. The crash plate has a guide portion and a crash portion connected to the guide portion. The guide portion is located outside the loading assembly, the crash portion is located in the cavity, and the crash portion has a measuring hole for the measuring assembly to pass through.

[0015] The loading component includes an active loading component and a passive loading component, which are located at opposite ends of the machine body, and the active loading component and / or the passive loading component are provided with weight reduction holes.

[0016] The measuring component includes a first deformation measuring element located in the cavity of the active loading element and a second deformation measuring element located in the cavity of the driven loading element, wherein the centerline of the first deformation measuring element and the centerline of the second deformation measuring element are collinear.

[0017] The loading device further includes a sensor disposed on the outer wall of the active loading member and the driven loading member, the sensor being located below the mounting groove.

[0018] The machine body includes a horizontal rail and a plurality of I-beams for supporting the horizontal rail. The loading device also includes guide wheels disposed on the outer wall of the loading component. The guide wheels cooperate with the horizontal rail to realize relative movement between the loading component and the horizontal rail.

[0019] The I-beams are evenly distributed along the horizontal rails, and there is a gap between the loading component and any of the I-beams, with the support plate located in the gap, so that the measuring device does not contact the machine body.

[0020] Secondly, this application also provides a measurement method for a measurement system applied to a horizontal anchor bolt testing machine, wherein the side wall of the loading assembly is provided with an installation groove for accommodating the anchor bolt, and the loading device further includes an anti-dislodgement component sleeved on the end of the anchor bolt; the measurement method includes the following steps:

[0021] Place the anchor bolt in the mounting groove and fit the anti-detachment sleeves on both ends of the anchor bolt;

[0022] Under the driving action of the second driving component, the measuring component abuts against the end face of the anchor rod;

[0023] Under the driving action of the first driving component, the loading component loads the anchor rod, causing it to deform in the horizontal direction;

[0024] The deformation of the anchor bolt is determined based on the changes in the values ​​of the measuring components.

[0025] Due to the adoption of the above technical solution, the beneficial effects achieved by this invention are as follows:

[0026] 1. The measuring system for a horizontal anchor bolt testing machine provided by this invention includes a loading component with a cavity and an open bottom. The measuring component is placed within the cavity, and the measuring device is not in contact with the loading component, thus separating the measuring device from the machine body. Therefore, even if the machine body deforms due to force during loading, the measuring device will not change position due to the deformation of the machine body. This ensures that the measuring device is not disturbed by the machine body and can work with the loading component to measure the deformation of the anchor bolt, significantly improving measurement accuracy and effectively reducing the testing machine's error. Furthermore, separating the measuring device from the machine body facilitates maintenance and replacement of the measuring device and expands its applicability. In addition, the measuring device is equipped with a second driving component connected to the measuring component. This second driving component can drive the measuring component to move horizontally within the cavity without contacting the loading component. This allows the measuring component to contact or separate from the end face of the anchor bolt and adapt to anchor bolts of different lengths or positions, facilitating adjustment and improving measurement accuracy.

[0027] 2. As a preferred embodiment, the support frame includes a support plate and legs, and is provided with a fixing block; specifically, the support plate can be configured to have a large support area, which can enhance the stability of the measuring device and make the measuring device less prone to tipping over; the cross-section of the fixing block can be smaller than the support plate and smaller than the opening, so that it can pass through the opening and not contact the loading device, thereby reducing the interference of the loading device on the measuring device and improving the measurement accuracy.

[0028] 3. In a preferred embodiment, the loading device is further provided with a mounting groove and a crash barrier. The mounting groove can fix the anchor rod and allow the anchor rod portion to be located in the cavity and in contact with the measuring component, thereby enabling the measuring component to measure the deformation of the anchor rod. The crash barrier includes a guide portion and a crash barrier portion. The anchor rod and the measuring component are respectively located on both sides of the crash barrier portion. During the placement of the anchor rod, the guide portion can guide the end of the anchor rod, minimizing the possibility of direct collision with the measuring component due to misalignment. The crash barrier portion further enhances the safety of the measuring component, preventing the anchor rod from causing destructive collisions with the measuring component in the horizontal direction, thereby helping to maintain and improve the measurement accuracy of the measuring device and extend the service life of the equipment.

[0041] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0042] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

They are only for the convenience of describing this invention and simplifying the description, 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 this invention.

[0044] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., 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, an electrical connection, or a communication 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 according to the specific circumstances.

[0045] In this invention, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0046] The testing machine involved in this invention is a horizontal testing machine, but this invention does not limit the specific type of the testing machine. The measurement system of this invention is applicable to horizontal testing machines used for tensile, compression, and relaxation tests. Furthermore, this invention does not limit the type of anchor bolt involved. The measurement system and measurement method are applicable to any type of anchor bolt, including full-length bonded anchor bolts, end-anchored anchor bolts, friction anchor bolts, prestressed anchor bolts, and self-drilling anchor bolts.

[0047] In this invention, such as Figure 1-4 As shown, a measuring system for a horizontal anchor bolt testing machine is provided. The measuring system includes a body 1 with a loading device 2 and a measuring device 3 disposed below the body 1. The loading device 2 includes a loading assembly 21 for clamping an anchor bolt 7 and a first driving member 22 connected to the loading assembly 21. Under the driving action of the first driving member 22, the loading assembly 21 can stretch the anchor bolt 7 in the horizontal direction. The measuring device 3 includes a support frame 32 and a measuring assembly 31 located above the support frame 32, and a second driving member 33 connected to the support frame 32 and the measuring assembly 31 respectively. The second driving member 33 can drive the measuring assembly 31 to contact or separate from the end face of the anchor bolt 7. The loading assembly 21 has a cavity 211 with a bottom opening. The measuring assembly 31 is at least partially located in the cavity 211, and the measuring device 3 does not contact the body 1 to reduce interference from the loading device 2 to the measuring device 3 during loading.

[0048] Specifically, in such Figure 1-4In one embodiment shown, the loading device 2 is used to fix the anchor bolt 7 and to load or unload the anchor bolt 7. The first driving member 22 can drive the loading assembly 21 to move in the horizontal direction, thereby the loading assembly 21 stretches the anchor bolt 7 to meet the test requirements. The loading component 21 is provided with a cavity 211. The bottom of the loading component 21 has an opening (not shown in the figure) and is connected to the cavity 211. The measuring device 3 passes through the opening at least partially through the bottom wall of the loading component 21 and is located in the cavity 211, and the measuring device 3 does not contact the loading component 21. The measuring component 31 is located in the cavity 211 and is in contact with the anchor rod 7 to measure the deformation of the anchor rod 7 during the test. The support frame 32 is located below the loading component 21 and is used to support the measuring device 3. The arrangement of the support frame 32 and the cavity 211 realizes the separation of the measuring device 3 from the body 1. During the test, the measuring component 31 only contacts the anchor rod 7, which minimizes the interference that the body 1 may cause to the measuring component 31, reduces the measurement error, and thus improves the test accuracy.

[0049] It should be noted that this application does not limit the specific structure of the first driving member 22 and the second driving member 33. In the embodiments provided in this application, cylinders are used as driving members. In addition, motors and other components may also be used.

[0050] As a preferred embodiment, such as Figure 3 As shown, the support frame 32 includes a support plate 321 and a leg 322 located below the support plate 321; the measuring device 3 also includes a connecting plate 34 and a fixing block 35 disposed on the support plate 321, the second driving member 33 is disposed at the top of the fixing block 35, and the second driving member 33 is connected to the measuring component 31 through the connecting plate 34.

[0051] Specifically, in such Figure 1-3 In one embodiment shown, the connecting plate 34 is connected to the measuring component 31 and the second driving member 33. The bottom surface of the second driving member 33 is connected to the top surface of the fixing block 35, and the bottom surface of the fixing block 35 is connected to the support plate 321. The second driving member 33 and the measuring component 31 are located in the cavity 211, the fixing block 35 is partially located in the cavity 211, and the support frame 32 is located below the loading device 2. The cross-section of the support plate 321 is larger than the opening, which can prevent the measuring component 31 from tipping over and improve the stability of the measuring device 3. The cross-section of the fixing block 35 is smaller than the opening, and by connecting the measuring component 31 and the support frame 32 through the fixing block 35, the measuring device 3 and the loading device 2 can be kept from contacting each other.

[0052] It should be noted that in the embodiments provided in this application, three support legs 322 are provided. This application does not limit the number of support legs and the number of support legs can be set according to specific test requirements and test intensity. This application also does not limit the specific shape of the fixing block 35, such as... Figure 3 The hollow cube shown can achieve a weight reduction effect. In addition, it can also be set as a column, solid cube, etc.

[0053] In a preferred embodiment, the side wall of the loading component 21 is provided with an installation groove 212 for accommodating the anchor rod 7, and the installation groove 212 is connected to the cavity 211; the loading device 2 also includes an anti-detachment component 23 sleeved on the end of the anchor rod 7, the anti-detachment component 23 being able to abut against the inner wall of the cavity 211 to prevent the anchor rod 7 from detaching from the installation groove 212 during loading.

[0054] Specifically, the mounting groove 212 is designed so that the anchor rod 7 can contact the measuring component 31 and be located on the same horizontal plane. In this embodiment, the mounting groove 212 is designed to extend to the top and has a width greater than that of the anchor rod 7. This does not interfere with the anchor rod 7 during the test and facilitates the placement and position adjustment of the anchor rod 7. The loading device 2 also includes an anti-detachment component 23, which is sleeved on the end of the anchor rod 7. The diameter of the anti-detachment component 23 is greater than the width of the mounting groove 212, and the anti-detachment component 23 is located in the cavity 211. During the loading process, the anti-detachment component 23 can always abut against the inner wall of the cavity 211 to fix the anchor rod 7.

[0055] It should be noted that the anti-detachment component 23 used in this embodiment is a nut, but this application does not limit the anti-detachment component 23. In addition, the shape of the mounting groove 212 is not limited. The mounting groove 212 should be able to place the anchor rod 7, minimize interference with the anchor rod 7, and be able to abut against the anti-detachment component 23 to fix the anchor rod 7.

[0056] In a preferred embodiment, the loading device 2 further includes a crash plate 24 fixed to the top wall of the loading assembly 21. The crash plate 24 has a guide portion 241 and a crash portion 242 connected to the guide portion 241. The guide portion 241 is located outside the loading assembly 21, and the crash portion 242 is located in the cavity 211. The crash portion 242 has a measuring hole through which the measuring assembly passes.

[0057] The anti-collision plate 24 is designed to minimize the contact between the anchor rod 7 and the measuring component 31 during placement in the cavity 211, and to prevent damage to the measuring component 31. The anti-collision plate 24 includes a guide portion 241 and an anti-collision portion 242. The anchor rod 7 and the measuring component 31 are located on opposite sides of the anti-collision portion 242. The guide portion 241 guides the end of the anchor rod 7, minimizing the risk of direct collision with the measuring component 31 due to misalignment. The anti-collision portion 242 further enhances the safety of the measuring component 31, preventing destructive impacts from the anchor rod 7 in the horizontal direction, thereby maintaining and improving the measurement accuracy of the measuring device 3 and extending the equipment's service life.

[0058] As a preferred embodiment, such as Figure 4-8 As shown, the loading component 21 includes an active loading component 213 and a driven loading component 214. The active loading component 213 and the driven loading component 214 are located at both ends of the body 1, and the active loading component 213 and / or the driven loading component 214 are provided with weight reduction holes.

[0059] Specifically, the active loading member 213 and the driven loading member 214 are used to fix the two ends of the anchor rod 7, and both the active loading member 213 and the driven loading member 214 are provided with mounting grooves 212 to accommodate the anchor rod 7; in addition, the setting of the weight reduction hole reduces the weight of the loading component 21, thereby reducing the weight of the testing machine.

[0060] As a preferred embodiment, such as Figure 4-8 As shown, the measuring component 31 includes a first deformation measuring component 311 and a second deformation measuring component 312 located in the cavity 211 of the active loading component 213 and the cavity 211 of the driven loading component 214, respectively, and the center line of the first deformation measuring component 311 and the center line of the second deformation measuring component 312 are collinear.

[0061] Specifically, both the first deformation measuring element 311 and the second deformation measuring element 312 are connected to the second driving element 33, that is, there are two second driving elements 33, each connected to the first deformation measuring element 311 and the second deformation measuring element 312 respectively. Furthermore, in the embodiments provided in this application, both the first deformation measuring element 311 and the second deformation measuring element 312 are contact-type digital dial indicators. However, this application does not limit the specific type of the first deformation measuring element 311 and the second deformation measuring element 312; they can be other contact-type deformation measuring instruments, such as mechanical dial indicators, or non-contact deformation measuring instruments, such as laser rangefinders.

[0062] Furthermore, it should be noted that during continuous loading, the anchor rod 7 may move horizontally due to the loading force. In this embodiment, the center lines of the first deformation measuring component 311 and the second deformation measuring component 312 are collinear, and the first deformation measuring component 311 and the second deformation measuring component 312 are symmetrically arranged in the cavity 211 of the active loading component 213 and the cavity 211 of the driven loading component 214. Therefore, the measuring component 31 actually measures the deformation at both ends of the anchor rod 7 simultaneously. The difference in the deformation at both ends is the deformation of the anchor rod 7, which is unrelated to the horizontal movement of the anchor rod 7. For example, if the active loading component 213 pulls one end of the anchor rod 7 towards the active component end, the other end of the anchor rod 7 will also move in the same direction. The relative deformation at both ends of the anchor rod 7 does not change, so it is not affected by the horizontal movement of the anchor rod 7.

[0063] In a preferred embodiment, the loading device 2 further includes a sensor 25 disposed on the outer wall of the active loading member 213 and the driven loading member 214, the sensor 25 being located below the mounting groove 212. Specifically, the sensor 25 is configured to identify whether the anchor rod 7 is placed in the mounting groove 212 and whether the anchor rod 7 has been installed in place.

[0064] In addition to the structure described above, the measuring device provided in this application may also include a positioning sensor (not shown in the figure) for detecting whether the two second driving members 33 are driven into position, wherein there are two positioning sensors and each is used to detect the two second driving members 33; and a control device (not shown in the figure) connected to the sensing member 25, the positioning sensor, the first driving member 22 and the second driving member 33 respectively.

[0065] To facilitate understanding, the measurement process of the measuring component will be explained below in conjunction with the working principles of the sensing element 25 and the position sensor:

[0066] First, the anchor bolt 7 is placed in the mounting groove 212. When the sensors 25 located on the active loading member 213 and the driven loading member 214 detect the anchor bolt 7, the sensors 25 send an identification signal to the control device. The control device then controls the two second driving members 33 to drive the first deformation measuring member 311 and the second deformation measuring member 312 to move horizontally towards the two end faces of the anchor bolt 7, until both positioning sensors send positioning signals to the control device. At this time, the first deformation measuring member 311 and the second deformation measuring member 312 have contacted the two end faces of the anchor bolt 7. The data measured by the first deformation measuring member 311 and the second deformation measuring member 312 changes and is sent to the control device in real time. Subsequently, the control device controls the first driving member 22 to drive the active loading member 213, thereby loading the anchor bolt 7. It should be noted that during the entire loading process, the first deformation measuring component 311 and the second deformation measuring component 312 must always be in contact with the two end faces of the anchor rod 7. Moreover, during the entire tensile process, the first deformation measuring component 311 and the second deformation measuring component 312 must be within their measuring range and sufficient margin must be reserved. It is not allowed to use the full range. This application does not impose restrictions on the specific type and range of the measuring components. For example, a contact digital dial indicator (with communication) with a measuring range of 0-50 mm can be selected. The deformation of the anchor rod 7 sample does not exceed 10 mm.

[0067] In one preferred embodiment, the body 1 includes a horizontal rail 4 and a plurality of I-beams 5 for supporting the horizontal rail 4. The loading device 2 also includes a guide wheel 6 disposed on the outer wall of the loading component 21. The guide wheel 6 cooperates with the horizontal rail 4 to realize the relative movement between the loading component 21 and the horizontal rail 4.

[0068] like Figure 1 , Figure 7 As shown, in the embodiment provided in this application, the loading component 21 is connected to the horizontal rail 4 via the guide wheel 6, and can move horizontally along the horizontal rail 4 via the guide wheel 6 to accommodate anchor rods 7 of different lengths; the horizontal rail 4 encloses a test cavity, and the measuring component 31, the loading component 21 and both ends of the anchor rod 7 are located in the test cavity.

[0069] In a preferred embodiment, the I-beams 5 are evenly distributed along the horizontal rails 4, and there is a gap between the loading component 21 and any of the I-beams 5, with the support plate 321 located in the gap, so that the measuring device 3 does not contact the machine body 1.

[0070] like Figure 8As shown, in the embodiments provided in this application, the support frame 32 is mounted above the I-beam 5 and does not contact the I-beam 5. This application does not limit the number and position of the I-beam 5. The I-beam 5 may not be provided below the support frame 32, or one or more I-beam 5 may be provided. As a preferred embodiment, the I-beam 5 does not contact the measuring device 3 to reduce the interference of the machine body 1 on the measuring device 3, thereby reducing the measurement error.

[0071] This invention also provides a measurement method applied to the measurement system of the aforementioned horizontal anchor bolt testing machine, such as... Figure 9 As shown, the measurement method includes the following steps:

[0072] S1. Place the anchor rod in the installation groove and fit the anti-detachment sleeve on both ends of the anchor rod;

[0073] S2. Under the driving action of the second driving component, the measuring component abuts against the end face of the anchor rod;

[0074] S3. Under the driving action of the first driving component, the loading component loads the anchor rod, causing it to deform in the horizontal direction;

[0075] S4. Determine the deformation of the anchor rod based on the changes in the values ​​of the measuring components.

[0076] It is important to note that in step S1, when the anti-detachment components are fitted onto both ends of the anchor rod, preferably, the anti-detachment components should not abut against the inner wall of the loading assembly and should be at a distance as small as possible. This ensures that the anchor rod can be smoothly inserted, minimizing the time required for the loading assembly to eliminate the gap at the anti-detachment components when loading begins, thus reducing the amount of loading displacement and the test time. Furthermore, in step S2, when the measuring components abut against the end face of the anchor rod, the numerical changes at both ends of the anchor rod must be collected simultaneously. If the values ​​at one or both ends do not change at this time, it is an abnormal state, and the test must be stopped for inspection. During a normal test, the values ​​displayed by the measuring components at both ends of the anchor rod change constantly, and the relative difference in the changes at each end is the deformation of the anchor rod.

[0077] For any parts not mentioned in this application, existing technologies may be used or referenced.

[0078] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0079] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
