Description

Technical Field

[0001] This utility model belongs to the field of material performance testing technology, specifically a high micro-slurry bonding strength testing device. Background Technology

[0002] In the field of pipeline repair engineering, the lining method is a widely used core repair technology, and its construction quality directly determines the service life and operational safety of the repaired pipeline.

[0003] In the lining method, high-micron slurry is a key functional material. The high-micron slurry needs to form a stable and firm bond with the inner wall of the pipeline to be repaired. This directly affects the pipeline's pressure resistance and leakage resistance during subsequent transport of media (such as liquids and gases). It is crucial to avoid secondary damage and media leakage after the pipeline is repaired.

[0004] However, existing repair samples are not convenient to handle during testing. The gap between the repair sample and the fixture is poorly designed; either the gap is too small, making it difficult to pick up or put down the repair sample, or the gap is too large, which further affects the limiting stability of the fixture and seriously restricts the efficiency of high micro-grout bonding strength testing. Therefore, a high micro-grout bonding strength testing device is proposed to address the above problems. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a high micro-grout bonding strength testing device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A high-strength adhesive bonding test device of this utility model includes a base, a guide column fixedly connected to the top of the base, a control panel installed on the side wall of the guide column, and a tension plate slidably connected to the inner wall of the guide column, the tension plate being controlled to move up and down via the control panel; two support frames fixedly connected to the top of the base, and clamp frames fixedly connected to the side walls of the support frames; a first limiting frame and a second limiting frame are provided on the top of the clamp frames, both the first limiting frame and the second limiting frame being connected to the clamp frames. The tension plate is set at a right angle. A tension sensor is fixedly connected to the bottom of the tension plate. The tension sensor is electrically connected to the tension plate. A connecting post is set at the bottom of the tension sensor. The tension sensor and the connecting post are fixedly connected by a first connecting rod. An adhesive plate is fixedly connected to the bottom of the connecting post. It is used to fix the sample to be repaired by applying high-micron paste. The sample to be repaired is set in the fixture frame during the test and is limited by the first limiting frame and the second limiting frame. There is a certain gap between the sample to be repaired and the fixture frame to facilitate picking up or placing.

[0007] Preferably, the inner wall of the clamp frame has two sliding grooves. The bottom of the first limiting frame and the second limiting frame are fixedly connected to a clamping plate. The first limiting frame and the second limiting frame are slidably arranged on the inner wall of the sliding groove through the clamping plate. The bottom of the clamping plate is fixedly connected to two self-locking push rods. Both self-locking push rods are electrically connected to the control panel. The output end of the self-locking push rod is fixedly connected to an expansion plate. The expansion plate is fixedly connected to the clamping plate. The clamping of the sample to be repaired in the clamp frame is completed by extending downward through the output ends of the two self-locking push rods.

[0008] Preferably, the bottom walls of the first and second limiting frames have two storage slots. The first limiting frame is rotatably connected to a rotating shaft, and a display plate is fixed to the bottom of the rotating shaft. The bottom of the display plate is flush with the bottom of the first and second limiting frames. By rotating the display plate, it is transferred to the storage slot at the bottom of the second limiting frame, thereby unfolding the display plate. The unfolding effect is used to limit the shape of the template to be repaired during stretching, thus avoiding deformation.

[0009] Preferably, a second connecting rod is fixedly connected to the top of the rotating shaft, and a reinforcing plate is fixedly connected to the top of the second connecting rod. The other end of the reinforcing plate is fixedly connected to the top of the display panel, which is used to reinforce the display panel when it is placed or rotated.

[0010] Preferably, a magnetic plate is fixed to the end of the display panel, and metal frames are fixed to both sides of the second limiting frame. The magnetic plate and the metal frames are attracted to each other, and the initial fixation of the display panel after it is unfolded is achieved by the attraction between the two.

[0011] Preferably, a rubber pad is fixed to the outer wall of the reinforcing plate to increase the friction when the reinforcing plate is held and the display board is rotated.

[0012] The beneficial effects of this utility model are: This utility model provides a high micro-grout bonding strength testing device. The device consists of a clamp frame, a first limiting frame, and a second limiting frame, forming a stable clamp system that provides a stable guarantee for high micro-grout bonding strength testing. The gap inside the clamp frame is larger than the sample to be repaired, which facilitates the removal or placement of the sample to be repaired and improves the efficiency of bonding testing.

[0013] This utility model provides a high micro-pulp bonding strength testing device. Through the unfolding and storage design of the display panel, it can effectively prevent the sample to be repaired from deforming during stretching when needed, thereby improving the reliability of the test results. When not needed, it can be stored vertically without affecting the placement and retrieval of the sample to be repaired, thus improving the practicality and flexibility of the device.

[0017] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Specific implementation examples are given below.

[0019] like Figure 1-4As shown, a high-strength adhesive bonding test device includes a base 1. A guide post 11 is fixedly connected to the top of the base 1. A control panel 12 is installed on the side wall of the guide post 11. A tension plate 13 is slidably connected to the inner wall of the guide post 11. The tension plate 13 is controlled to move up and down by the control panel 12. Two support frames 14 are fixedly connected to the top of the base 1. A clamp frame 15 is fixedly connected to the side wall of the support frame 14. A first limiting frame 16 and a second limiting frame 17 are provided on the top of the clamp frame 15. The first limiting frame 16 and the second limiting frame 17 are both set at right angles to the connection point of the clamp frame 15. The bottom of the tension plate 13 is fixedly connected to the support frame 14. A tension sensor 110 is connected to a tension plate 13. A connecting post 19 is provided at the bottom of the tension sensor 110. The tension sensor 110 and the connecting post 19 are fixedly connected by a first connecting rod 111. An adhesive plate 18 is fixedly attached to the bottom of the connecting post 19 for fixing the sample 100 to be repaired by applying a high-micron paste. During testing, the sample 100 is positioned within a clamping frame 15 and is limited by a first limiting frame 16 and a second limiting frame 17. A certain gap exists between the sample 100 and the clamping frame 15 for easy handling or placement. First, the sample 100 to be repaired is placed in the clamp frame 15, which is fixed to the side wall of the support frame 14 at the top of the base 1. The clamp frame 15 is limited by the first limiting frame 16 and the second limiting frame 17 at the top. High-quality adhesive paste is applied to the adhesive plate 18. The tension plate 13, which is slidably connected to the inner wall of the guide post 11, is moved downwards via the control panel 12, causing the high-quality adhesive paste on the adhesive plate 18 to contact and fix the sample 100 to be repaired. The adhesive plate 18 is connected to the tension sensor 110 at the bottom of the tension plate 13 via the connecting post 19 and the first connecting rod 111. During testing, the control panel 12 controls the tension plate 13 to move upwards, and the tension sensor... 110 Real-time detection of tensile force data during the stretching process enables testing of high micronized slurry bonding strength. After the test, tools can be used to separate the sample 100 to be repaired from the bonding plate 18, and the sample 100 to be repaired can be taken out using the gap between the sample 100 to be repaired and the clamp frame 15. This step, through the clamp frame 15, the first limiting frame 16 and the second limiting frame 17, constitutes a stable clamping system, providing a stable guarantee for the high micronized slurry bonding strength test. The gap in the clamp frame 15 is larger than the sample 100 to be repaired, which facilitates the taking out or putting in the sample 100 to be repaired, improving the efficiency of bonding testing.

[0020] like Figure 1-4As shown, the inner wall of the clamp frame 15 has two sliding grooves 2. The bottom of the first limiting frame 16 and the second limiting frame 17 are fixedly connected to a clamping plate 21. The first limiting frame 16 and the second limiting frame 17 are slidably arranged on the inner wall of the sliding groove 2 through the clamping plate 21. The bottom of the clamping plate 21 is fixedly connected to two self-locking push rods 22. Both self-locking push rods 22 are electrically connected to the control panel 12. The output end of the self-locking push rod 22 is fixedly connected to an expansion plate 23. The expansion plate 23 is fixedly connected to the clamping plate 21. The downward extension of the output end of the two self-locking push rods 22 completes the clamping of the sample to be repaired in the clamp frame 15. Clamping of plate 100: After the plate 100 to be repaired is placed in the fixture frame 15, the control panel 12 controls the output end of the self-locking push rod 22 to extend downward, driving the expansion plate 23 and the clamping plate 21 to move, so that the clamping plate 21 slides in the groove 2 on the inner wall of the fixture frame 15. With the cooperation of the first limit frame 16 and the second limit frame 17, the clamping and fixing of the plate 100 to be repaired in the fixture frame 15 is completed. This step, through the synergistic action of the two self-locking push rods 22, can achieve stable clamping of the plate 100 to be repaired, avoid displacement of the plate 100 to be repaired during the test, and ensure the accuracy of the test results.

[0021] like Figure 1-4 As shown, the bottom walls of the first limiting frame 16 and the second limiting frame 17 have two storage slots 3. A rotating shaft 31 is rotatably connected inside the first limiting frame 16. A display plate 32 is fixedly connected to the bottom of the rotating shaft 31. The bottom of the display plate 32 is flush with the bottom of the first limiting frame 16 and the second limiting frame 17. By rotating the display plate 32, it is moved to the storage slot 3 at the bottom of the second limiting frame 17, thus unfolding the display plate 32. This unfolding effect helps to limit the shape of the template 100 to be repaired during stretching, preventing deformation. Rotating the end of the display plate 32 drives the rotating shaft 32 to rotate. The rotating shaft 31 rotates, causing the display plate 32 to rotate out of the storage groove 3 at the bottom of the first limiting frame 16 and transfer to the storage groove 3 at the bottom of the second limiting frame 17, thus realizing the unfolding of the display plate 32. During the tensile test, the unfolded display plate 32 is used to limit the shape of the sample 100 to be repaired. This step, through the unfolding and storage design of the display plate 32, can effectively prevent the sample 100 to be repaired from deforming during stretching when needed, improving the reliability of the test results. When not needed, it can be stored vertically without affecting the placement and retrieval of the sample 100 to be repaired, thus improving the practicality and flexibility of the device.

[0022] like Figure 1-4As shown, a second connecting rod 4 is fixedly connected to the top of the rotating shaft 31, and a reinforcing plate 41 is fixedly connected to the top of the second connecting rod 4. The other end of the reinforcing plate 41 is fixedly connected to the top of the display plate 32, which is used to reinforce the display plate 32 when it is placed or rotated. The second connecting rod 4 at the top of the rotating shaft 31 is fixedly connected to the reinforcing plate 41, and the other end of the reinforcing plate 41 is fixedly connected to the top of the display plate 32. After the display plate 32 is rotated or unfolded, it reinforces the connection between the display plate 32 and the rotating shaft 31. This step can effectively prevent the display plate 32 from shaking or falling off during rotation or operation, ensuring the stability of the shape of the display plate 32 in relation to the sample 100 to be repaired, and further improving the reliability of the test results.

[0023] like Figure 1-4 As shown, a magnetic plate 5 is fixed to the end of the display panel 32, and metal frames 51 are fixed to both sides of the second limiting frame 17. The magnetic plate 5 and the metal frames 51 are attracted to each other, and the initial fixation of the display panel 32 after it is unfolded is achieved through the attraction between the two. When the display panel 32 is unfolded to the storage groove 3 at the bottom of the second limiting frame 17, the magnetic plate 5 at the end of the display panel 32 attracts the metal frames 51 on both sides of the second limiting frame 17, and the initial fixation of the display panel 32 after it is unfolded is achieved. This step initially fixes the unfolded display panel 32 to prevent it from shifting during the test, ensuring the continuity and stability of the shape limitation of the sample 100 to be repaired, and further improving the accuracy of the test results.

[0024] like Figure 1-4 As shown, a rubber pad is fixed to the outer wall of the reinforcing plate 41 to increase the friction when the reinforcing plate 41 is held and the display plate 32 is rotated. When the operator holds the reinforcing plate 41 and rotates the display plate 32, the rubber pad on the outer wall of the reinforcing plate 41 increases the friction between the hand and the reinforcing plate 41. This step can prevent the operator from slipping when rotating the display plate 32, making the unfolding and folding of the display plate 32 smoother and less strenuous, thus improving the ease of operation of the device. Working principle: First, the sample 100 to be repaired is placed in the clamp frame 15, which is fixed to the side wall of the support frame 14 at the top of the machine base 1. The clamp frame 15 is limited by the first limiting frame 16 and the second limiting frame 17 at the top. High-efficiency paste is applied to the adhesive plate 18. The tension plate 13, which is slidably connected to the inner wall of the guide post 11, is moved downward by the control panel 12, so that the high-efficiency paste on the adhesive plate 18 contacts and fixes the sample 100 to be repaired. The adhesive plate 18 is connected to the tension sensor 110 at the bottom of the tension plate 13 through the connecting post 19 and the first connecting rod 111. During testing, the control panel 12 controls the tension plate 13 to move upward, and the tension sensor 110 detects the tension data in real time during the tensile process, thereby realizing the test of the high micro-grout bonding strength. After the test, a tool can be used to separate the sample 100 to be repaired from the bonding plate 18, and the sample 100 to be repaired can be taken out using the gap between the sample 100 to be repaired and the clamp frame 15. After the sample 100 to be repaired is placed in the clamp frame 15, the control panel 12 controls the output end of the self-locking push rod 22 to extend downward, driving the expansion plate 23 and the clamping plate 21 to move, so that... The clamping plate 21 slides within the groove 2 on the inner wall of the clamping frame 15, cooperating with the first limiting frame 16 and the second limiting frame 17 to clamp and fix the sample 100 to be repaired within the clamping frame 15. Rotating the end of the display plate 32 drives the rotating shaft 31 to rotate, causing the display plate 32 to rotate out of the storage groove 3 at the bottom of the first limiting frame 16 and transfer to the storage groove 3 at the bottom of the second limiting frame 17, thus unfolding the display plate 32. During tensile testing, the unfolded display plate 32 is used to define the shape of the sample 100 to be repaired. The second connecting rod 4 at the top of the rotating shaft 31 is reinforced... Plate 41 is fixedly connected, and the other end of the reinforcing plate 41 is fixedly connected to the top of the display plate 32. After the display plate 32 is rotated or unfolded, it reinforces the connection between the display plate 32 and the rotating shaft 31. When the display plate 32 is unfolded to the storage groove 3 at the bottom of the second limiting frame 17, the magnetic plate 5 at the end of the display plate 32 attracts the metal frame 51 on both sides of the second limiting frame 17, thus achieving the initial fixation of the display plate 32 after unfolding. When the operator holds the reinforcing plate 41 and drives the display plate 32 to rotate, the rubber pad on the outer wall of the reinforcing plate 41 increases the friction between the hand and the reinforcing plate 41.
