Description

Technical Field

[0001] The invention relates to the technical field of basalt fiber mesh detection, and in particular to a basalt fiber composite reinforcement mesh strength testing device and method. Background Art

[0002] Basalt fiber composite mesh is a new type of building material, mainly made of basalt fiber. Basalt fiber is a high-strength, corrosion-resistant fiber material made by melting basalt and drawing it. Basalt fiber composite mesh is usually used to reinforce concrete structures, which can improve the crack resistance, impact resistance and integrity of concrete. The basalt fiber composite mesh strength test is a process of evaluating the performance and quality of mesh materials made of basalt fibers. It measures the strength of the mesh material under tensile load to ensure that the mesh material has sufficient tensile resistance during application to avoid breakage or deformation during use.

[0003] Generally, a tensile strength tester is used to test the mesh material. During the test, the mesh material is fixed between the two clamping ends of the tensile strength tester, and then the mesh material is stretched until the mesh material breaks. The tensile force changes during the stretching process are transmitted to the computer for processing through the tensile pressure sensor to obtain the tensile resistance of the mesh material. However, the above test method still has the following shortcomings: 1. The existing tensile resistance test only stretches the two ends of the mesh material and only measures the longitudinal tensile condition of the mesh material. In actual use, the basalt fiber composite rib mesh is subjected to both transverse and longitudinal tensile forces. The result of only longitudinal tensile test is not comprehensive enough, which affects the accuracy of the tensile resistance test result of the mesh material; 2. In actual use, the basalt fiber composite rib mesh will be subjected to tensile forces in addition to the tensile forces along the warp or weft direction, and the existing tensile strength test is generally performed along the warp or weft of the mesh material.

[0040] See also Figure 1 and Figure 3 The transverse stretching mechanism 3 includes a transverse moving component 31 slidably installed inside the movable groove 11, and a movable clamping mechanism 2 32 symmetrically distributed on the left and right is installed on the transverse moving component 31.

[0041] See also Figure 1 , Figure 2 , Figure 3 and Figure 6 The angle positioning mechanism 5 includes an arc-shaped slide groove 51 opened on the top of the support platform 1 and located in front of the movable groove 11. The center of the arc-shaped slide groove 51 coincides with the axis of the fixed column 21.

[0042] The angle line 53 is used to indicate the rotation angle of the longitudinal moving component 22, so that the longitudinal moving component 22 can be accurately rotated to a suitable angle, which is convenient for testing the tensile strength of the mesh material under oblique tensile states at different angles.

[0043] See also Figure 2 , Figure 3 and Figure 6 The longitudinal moving component 22 includes a first guide rail 221 whose rear end is rotatably connected to the fixed column 21.

The front end of the first guide rail 221 is installed with a first driving motor 224 that drives the first lead screw 222 to rotate.

[0044] The first driving motor 224 drives the first lead screw 222 to rotate, so that the first slider 223 slides forward along the first guide rail 221, which can increase the distance between the movable clamping mechanism 23 and the fixed clamping mechanism 24, so that the movable clamping mechanism 23 and the fixed clamping mechanism 24 can perform longitudinal stretching detection on the mesh material. The first guide rail 221 can rotate around the fixed column 21, so that the movable clamping mechanism 23 can move horizontally and obliquely, which is convenient for oblique stretching detection.

The fixed clamping mechanism 24 has the same structure as the clamping assembly 232, which will not be repeated here.

[0046] When fixing the mesh material, place the edge of the mesh material on the horizontal section at the bottom of the U-shaped frame 2321, then rotate the threaded rod 2323 to push the clamping plate 2322 downward and press it against the edge of the mesh material. The guide rod 2324 guides the clamping plate 2322 to improve the stability of the clamping plate 2322 moving up and down.

[0047] See also Figure 1 , Figure 3 , Figure 4 and Figure 7 The lateral movement component 31 includes a second guide rail 311 which is slidably installed in the movable groove 11. The second guide rail 311 is internally rotatably connected with a bidirectional lead screw 312. The left and right ends of the bidirectional lead screw 312 are threadedly connected with a second slider 313. The second slider 313 is slidably installed in the second guide rail 311. A second drive motor 314 that drives the bidirectional lead screw 312 to rotate is fixedly installed on the front side of the second guide rail 311.

The structure of the movable clamping mechanism 2 32 is the same as that of the movable clamping mechanism 1 23, which will not be repeated here.

[0048] After the two movable clamping mechanisms 2 32 fix the left and right sides of the mesh material respectively, the second driving motor 314 drives the bidirectional lead screw 312 to rotate, so that the second sliders 313 at both ends move away from each other along the second guide rail 311, thereby driving the two movable clamping mechanisms 2 32 away from each other, so that the two movable clamping mechanisms 2 32 perform lateral stretching detection on the mesh material.

[0049] See also Figure 2 and Figure 5 The movable adjustment mechanism 4 includes a linear slide groove 41 opened inside the support platform 1, and the internal rotation of the linear slide groove 41 is connected to the second lead screw 42, and the external thread of the second lead screw 42 is connected to the third slider 43.

A pushing block 524 is fixedly connected to the front side of the vertical section of the L-shaped positioning block 522. The front end of the pushing block 524 slides through to the front of the first guide rail 221.

[0052] By pressing the pushing block 524 backward, the L-shaped positioning block 522 can be pushed to move backward, so that the horizontal section of the L-shaped positioning block 522 is separated from the positioning hole 521, thereby releasing the lock of the first guide rail 221, allowing the first guide rail 221 to slide left and right along the arc-shaped slide groove 51. When sliding to a suitable position, the pushing block 524 is released, and the rebound force of the return spring 523 is used to push the L-shaped positioning block 522 forward, so that the horizontal section of the L-shaped positioning block 522 is reinserted into the corresponding positioning hole 521, so as to facilitate the rapid positioning of the first guide rail 221.

After the test is completed, the carrier 83 is put back from the installation port 811 into the corresponding U-shaped limit frame 821; the U-shaped limit frame 821 limits the carrier 83, so that the carrier 83 can only move in the opening direction of the U-shaped limit frame 821, thereby avoiding the deviation of the carrier 83.

[0058] When the fourth driving motor 861 drives the synchronous wheel 1 862 to rotate counterclockwise, due to the transmission of the groove wheel structure 84, the turntable 82 will rotate intermittently clockwise, and move the carriers 83 from small to large to the delivery port 812 one by one, and the synchronous wheel 1 862 drives the synchronous wheel 2 864 to rotate counterclockwise through the synchronous belt, and then the synchronous wheel 2 864 drives the shaft 863 to rotate through the ratchet pawl structure 865, and drives the eccentric cam 855 to rotate through the shaft 863, so that the protruding end of the eccentric cam 855 pushes the push rod 852 and the push plate 853 to move forward, so that the push plate 853 pushes the corresponding carrier 83 out of the delivery port 812, and then the protruding end of the eccentric cam 855 rotates to the direction away from the push rod 852, and the rebound force of the reset spring 2 854 is used to push the push rod 852 to move backward and reset, and the rotation of the turntable 82 and the push of the push rod 852 are performed alternately, which is convenient for measuring the tensile strength of the mesh material when it is subjected to different loads.

[0059] When the fourth drive motor 861 drives the synchronous wheel 1 862 to rotate clockwise, the turntable 82 will intermittently move counterclockwise, and the synchronous wheel 1 862 drives the synchronous wheel 2 864 to rotate clockwise through the synchronous belt. At this time, the ratchet pawl structure 865 no longer drives the shaft 863 and the eccentric cam 855 to rotate, which can prevent the push plate 853 from pushing out the carriers 83 one by one, and facilitates the selective rotation of a certain carrier 83 to the delivery port 812. Then the fourth drive motor 861 drives the synchronous wheel 1 862 to rotate counterclockwise to push out the required carrier 83, thereby improving the flexibility of detection and increasing the diversity of detection.

[0060] See also Figure 2 , Fig.11 and Fig.12 A pressing mechanism 9 is also installed at the bottom of the delivery mechanism 8, and the pressing mechanism 9 includes a mounting groove 91 opened at the bottom edge of the turntable 82, and a squeezing column 92 is detachably installed in the mounting groove 91. A mounting plate 921 is fixedly connected to the top of the squeezing column 92, and the mounting plate 921 cooperates with the mounting groove 91. A fixing component 93 for locking the squeezing column 92 is installed on the turntable 82.

[0061] See also Fig.11 and Fig.12 The fixing assembly 93 includes a socket 931 provided on the rear side of the mounting slot 91, a movable pin 932 located in front of the mounting slot 91 is slidably installed at the bottom of the turntable 82, a return spring 933 is fixedly connected between the front side of the movable pin 932 and the shell 81, an insert block 934 matching the socket 931 is integrally formed on the rear side of the mounting plate 921, a pin hole 935 is provided on the front side of the mounting plate 921, and the movable pin 932 is plugged into and matched with the pin hole 935.

[0062] By setting a compression mechanism 9 at the bottom of the turntable 82, using the up and down moving mechanism 7 to drive the delivery mechanism 8 to move downward, and then the delivery mechanism 8 drives the compression mechanism 9 to move downward, the extrusion column 92 can apply downward pressure to the surface of the mesh material, which is convenient for performing surface compression testing on the mesh material and measuring the compressive resistance of the mesh material surface when it is compressed at a fixed position. At the same time, the extrusion column 92 is driven to move by the counterclockwise rotation of the turntable 82, and the position of the extrusion column 92 can be continuously adjusted, so that the extrusion column 92 can perform compression testing on different parts of the mesh material surface, thereby improving the detection effect.

[0063] When the extrusion column 92 is to be removed, the movable pin 932 is pushed to move in the direction away from the socket 931 to separate the movable pin 932 from the pin hole 935, and then the extrusion column 92 is moved forward to pull the plug block 934 out of the socket 931, and then the extrusion column 92 is moved downward to directly separate the mounting plate 921 from the mounting slot 91; during installation, the movable pin 932 is pushed to move in the direction away from the socket 931, and then the mounting plate 921 is placed in the mounting slot 91, and then the mounting plate 921 is moved backward to insert the plug block 934 into the socket 931, and then the movable pin 932 is released, so that the movable pin 932 is inserted into the pin hole 935 under the action of the rebound force of the return spring 933 to be locked.

[0064] By installing the extrusion column 92 in a detachable manner, when the mesh material is not subjected to a fixed position compression test, the extrusion column 92 is removed to prevent the extrusion column 92 from affecting the operation of the delivery mechanism 8, so that the delivery mechanism 8 can be moved down to the surface close to the mesh material to deliver the carrier 83, which is beneficial to ensuring the stability of the carrier 83 when it is delivered.

[0065] See also Figure 1-Figure 12The present invention also provides a basalt fiber composite rib mesh strength test method, which specifically includes the following steps: S1. Fixing the front and rear ends of the mesh material: first, place the front end of the mesh material between the U-shaped frame 2321 and the clamping plate 2322, and then rotate the threaded rod 2323 to push the clamping plate 2322 to move downward to clamp the mesh material. Similarly, control the fixed clamping mechanism 24 to tighten the rear end of the mesh material, and then the first drive motor 224 drives the first lead screw 222 to rotate, so that the first slider 223 drives the movable clamping mechanism 23 to move forward, and pulls the mesh material to a naturally straight state.

[0066] S2. Fix the left and right ends of the mesh material: first, drive the second lead screw 42 to rotate through the third drive motor 44, so that the third slider 43 drives the transverse stretching mechanism 3 to move forward and backward, and moves the transverse stretching mechanism 3 to the appropriate positions on the left and right sides of the mesh material, and then drive the bidirectional lead screw 312 to rotate through the second drive motor 314, so that the second slider 313 drives the movable clamping mechanism 2 32 to move toward the direction close to the mesh material, so that the movable clamping mechanism 2 32 is close to the left and right sides of the mesh material, and then the movable clamping mechanism 2 32 is controlled in the same operating mode as the clamping assembly 232 to tighten the left and right sides of the mesh material.

[0067] S3. Perform a tensile test on the mesh material: the first drive motor 224 drives the first lead screw 222 to rotate, so that the first slider 223 drives the movable clamping mechanism 23 to move forward along the first guide rail 221, so that the movable clamping mechanism 23 stretches the mesh material forward and backward, and the second drive motor 314 drives the bidirectional lead screw 312 to rotate, so that the second slider 313 drives the movable clamping mechanism 2 32 to move away from the center of the second guide rail 311, so that the movable clamping mechanism 2 32 stretches the mesh material left and right until the mesh material breaks, and the tensile resistance of the mesh material under simultaneous lateral and longitudinal tension is tested.

[0068] S4. Perform an oblique tensile test on the mesh material: When an oblique tensile test is to be performed, repeat step 1 to clamp the front and rear ends of a new mesh material, and then press the pushing block 524 backward to separate the L-shaped positioning block 522 from the positioning hole 521, then rotate the first guide rail 221 to adjust it to a suitable angle, and then release the pushing block 524, and push the L-shaped positioning block 522 forward through the rebound force of the reset spring 523, so that the L-shaped positioning block 522 is inserted into the corresponding positioning hole 521, and the first guide rail 221 is fixed. Then the first drive motor 224 drives the first lead screw 222 to rotate, so that the first slider 223 drives the movable clamping mechanism 23 to move away from the fixed clamping mechanism 24, and the mesh material is obliquely stretched until the mesh material breaks, and the tensile strength of the mesh material under oblique tension is tested.

[0069] S5. Perform a load-bearing tensile test on the mesh material: Repeat steps S1 and S2 to clamp the new mesh material, push the housing 81 downward through the electric push rod, so that the turntable 82 fits the surface of the mesh material, and then the fourth drive motor 861 drives the synchronous wheel 1 862 to rotate counterclockwise. Due to the transmission of the groove wheel structure 84, the turntable 82 will rotate intermittently clockwise to move the corresponding carrier 83 to the delivery port 812. The synchronous wheel 1 862 drives the synchronous wheel 2 862 through the synchronous belt. 64 rotates counterclockwise, and then the synchronous wheel 864 drives the shaft 863 to rotate through the ratchet pawl structure 865, and drives the eccentric cam 855 to rotate through the shaft 863, so that the protruding end of the eccentric cam 855 pushes the push rod 852 and the push plate 853 to move forward, so that the push plate 853 pushes the corresponding carrier 83 out of the delivery port 812, so that the carrier 83 falls onto the mesh material, and then repeats step S3 to perform a tensile test on the mesh material to determine the tensile resistance of the mesh material when bearing heavy objects.

[0070] S6. Install the compression mechanism 9: push the movable pin 932 to move away from the socket 931, then put the mounting plate 921 into the mounting groove 91, then move the mounting plate 921 backward to insert the insert block 934 into the socket 931, then release the movable pin 932, so that the movable pin 932 is inserted into the pin hole 935 under the action of the rebound force of the reset spring 933 to be locked.

[0071] S7. Perform compression test on the mesh material: Repeat step S1 to clamp the front and rear ends of the new mesh material, and then use the electric push rod to push the delivery mechanism 8 and the compression mechanism 9 downward. When the mesh material is in a horizontal and naturally straight state, the extrusion column 92 compresses the mesh material until the mesh material breaks, and the compression resistance of the mesh material when it is subjected to compression force is tested.

[0072] S8. Perform compression test on different parts of the mesh material: When the fourth drive motor 861 drives the synchronous wheel 862 to rotate clockwise, the turntable 82 will intermittently rotate counterclockwise due to the transmission of the groove wheel structure 84. The turntable 82 is used to drive the extrusion column 92 to move, thereby adjusting the position of the extrusion column 92, and then repeat step S7 to perform compression test to test the compressive resistance of different positions of the mesh material when subjected to compressive force.

[0073] S9. Disassemble the compression mechanism 9: push the movable pin 932 to move away from the socket 931 to separate the movable pin 932 from the pin hole 935, then move the extrusion column 92 forward to pull the insert block 934 out of the socket 931, and then move the extrusion column 92 downward to directly separate the mounting plate 921 from the mounting groove 91.
