Description

Technical Field

[0001] The invention belongs to the technical field of material performance detection, and in particular relates to a road performance testing device for multi-solid waste-based cementitious materials. Background Art

[0002] With the enhancement of environmental awareness and the promotion of the concept of resource recycling, the application of multi-solid waste-based cementitious materials in road engineering is becoming more and more extensive. Multi-solid waste-based cementitious materials have emerged as a new type of building material. They are cementitious materials prepared by mixing and treating various solid wastes according to a certain proportion and process. Multi-solid waste-based cementitious materials have unique performance in road performance such as compressive strength, flexural strength, durability, and skid resistance due to their complex sources and diverse components. Special testing equipment is required to accurately evaluate their applicability and reliability in road engineering; After checking, the disclosure (announcement) number: CN202420011675.5 discloses a material pressure detection device for highway engineering. This technology discloses "a material pressure detection device for highway engineering, including a pressure plate, a first hydraulic rod is fixedly arranged on the top of the pressure plate, and a fixed block is fixedly arranged on the outer side of the first hydraulic rod. It has the advantages of being able to conveniently locate the detection material at the center of the pressure plate, making the detection more accurate, and this device can conveniently collect the material residue of the support seat, thereby reducing the workload of the user"; however, in actual use, it is difficult to accurately simulate the above-mentioned complex working conditions and stress states faced by multi-solid waste-based cementitious materials in the actual road use process. In terms of pressure resistance testing, traditional equipment can often only perform a single static loading test, which is unable to truly reproduce the dynamic vertical pressure changes of vehicle tires on the road surface, and is even more difficult to simulate the actual pressure distribution differences of different vehicle loads and different road locations, resulting in large deviations in the evaluation of the pressure resistance of multi-solid waste-based cementitious materials, and unable to provide accurate and reliable data support for their reasonable application in different road areas. At the same time, in terms of material deformation monitoring, it mostly relies on complex electronic sensors and cumbersome data processing systems, which are not only costly and complicated to operate, but also unable to simply show the deformation of the material, and are difficult to implement effectively in some field test scenarios or simple laboratory conditions.

At the same time, it can monitor the deformation of multi-solid waste-based cementitious materials during static pressure or dynamic rolling in real time and leave intuitive marks. With the scale lines set on the marking plate, it is convenient for testers to directly observe the position and length changes of the marks, so as to quickly and intuitively understand the deformation degree of the material during the compression process, and can also intuitively compare the deformation degree of the material under different pressure states.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention adds a static and dynamic detection component, and through the coordinated use of structures such as a U-shaped cover, a slider, an electric slide rail, a load-bearing plate, a connecting sleeve, a U-shaped connecting frame and a pressure roller, the pressure output by the hydraulic rod is controlled to prompt the pressure roller to detect the pressure resistance of the multi-solid waste-based cementitious material, which can simulate the vertical pressure of the vehicle tire on the road surface. This simulation method is closer to the actual traffic load situation, can more accurately evaluate the pressure resistance of the material in the actual road environment, and can simulate the pressure resistance of the material under different vehicle loads; The position of the pressure roller relative to the pressure detection of the multi-solid waste-based cementitious material can be arbitrarily adjusted. The ability to freely adjust the position of the pressure roller can simulate the actual pressure conditions at different road locations, and can better study the local pressure resistance of the multi-solid waste-based cementitious material when dealing with complex traffic loads, and comprehensively evaluate the pressure resistance of the material at different locations, thereby providing more accurate data support for the application of the material in different areas of the road; At the same time, the hydraulic rod is controlled to control the electric slide rail to drive the slider to move back and forth on the surface of the electric slide rail while causing the pressure roller to apply pressure to the surface of the multi-solid waste-based cementitious material. This can then cause the pressure roller to move back and forth on the multi-solid waste-based cementitious material to perform a dynamic roller compression test, which can well simulate the dynamic pressure that the material is subjected to when a vehicle travels back and forth on the road. This simulation method is more in line with actual traffic conditions and can more realistically reflect the compression performance of the material under actual road conditions than a static compression test. For example, on a busy road, frequent passing of vehicles will cause the road surface material to withstand continuous The dynamic roller compression test can evaluate the durability of the material under such long-term dynamic pressure. At the same time, the dynamic reciprocating roller compression will put the material in a state of repeated stress, which is helpful to evaluate the fatigue resistance of the multi-solid waste-based cementitious materials, the ability to resist deformation, whether stratification occurs, etc. Under long-term and repeated pressure, the internal structure of the material may gradually be damaged, such as the generation and expansion of microcracks. The dynamic roller compression test can be used to observe the changes in the performance of the material under different reciprocating times, such as strength attenuation, deformation increase, etc., so as to judge whether the material is suitable for use in roads and other occasions that are subjected to dynamic loads.

[0016] 2. The present invention adds a deformation observation component. Through the coordinated use of structures such as a fixed plate, an L-shaped guide frame, a sliding connector, a connecting rod, a U-shaped abutment frame, an abutment plate, a second spring, a T-shaped marking rod and a marking plate, when the multi-solid waste-based cementitious material is deformed due to pressure, the T-shaped marking rod elastically arranged by the second spring and slidably connected in the yield sleeve can slide to one side and leave a mark on the surface of the marking plate. This design can monitor the deformation of the multi-solid waste-based cementitious material during static pressure or dynamic rolling in real time and leave an intuitive mark. With the scale lines set on the marking plate, it is convenient for testers to directly observe the position and length changes of the mark, so as to quickly and intuitively understand the deformation degree of the material during the pressure process. Compared with the traditional method of relying on complex electronic sensors and data processing to monitor deformation, this visual marking method is simpler and more direct, does not require additional instruments and equipment to interpret data, and can easily judge the deformation of the material even if there is no complex monitoring system on site; The T-shaped marking rod is set by the elasticity of the second spring to ensure the accuracy of the marking. When the material is slightly deformed, the abutment plate is subjected to force, and the sliding of the guide square rod can accurately transmit the displacement, so that the positioning sleeve moves accordingly, and the elastically connected T-shaped marking rod can sensitively follow the movement and leave a mark on the marking plate. The elasticity of the second spring can compensate for some tiny mechanical gaps and vibrations, avoiding inaccurate marking due to looseness or errors between mechanical parts. This high-precision deformation recording method helps to study the deformation characteristics of materials under different pressures in more detail, and provide more accurate data support for evaluating performance indicators such as the material's compressive resistance, fatigue resistance, ability to resist deformation, and whether stratification occurs. At the same time, the marks on the marking board can serve as an important basis for comparing material properties. When testing multi-solid waste-based cementitious materials of different formulations or batches, the marking conditions of each material can be compared. By comparing the starting position, moving distance and change trend of the marks, the deformation differences of different materials under the same pressure conditions can be intuitively seen, thereby conveniently screening out materials with better performance. This comparison method is simple and easy, does not require complex data analysis software, and is convenient for rapid material performance comparison between laboratories or between different testers.

[0017] 3. The present invention adds a limit anti-deviation component. Through the coordinated use of the H-shaped sliding rod, screw rod 1, screw block, gear 1, screw rod 2, fixed support plate, clamping plate, pressure plate, T-shaped rod and elastic pressure plate and other structures provided in the component, when the compressive performance of the multi-solid waste-based cementitious material is tested, the clamping plate can be pressed against the side of the multi-solid waste-based cementitious material simultaneously, which can effectively prevent the material from being displaced during the test. By fixing the clamping plate, the material can always be kept in a predetermined position during the test to ensure the accuracy of the test. At the same time, the stable material fixation helps to ensure the safety of the test process and avoids accidental movement of the material under pressure, which may cause damage to the equipment itself and pose a safety threat to the operator. The elastic pressure plate connected by the T-bar and the spring is pressed against the upper surface of the multi-solid waste-based cementitious material, and can cooperate with the side clamping plate to fix the material from multiple directions. This multi-directional fixing method can more effectively prevent the material from shifting during the test, further ensure the stability of the material position, and improve the test accuracy; The elastic pressure plate is elastically connected to the T-bar and spring three, and can automatically adjust the pressing force according to the shape of the material surface. When there is a convex part on the material surface, spring three will be compressed so that the elastic pressure plate can fit the convex part. When encountering a concave part, spring three can stretch to ensure that the elastic pressure plate always maintains good contact with the material surface. This adaptive pressing method can better adapt to the irregularities of the material surface and apply pressure evenly. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The working principle and use process of the present invention are as follows: when the road performance testing equipment for multi-solid waste-based cementitious materials is used, the multi-solid waste-based cementitious materials are first placed on the surface of the bearing plate 25, and then the extension of the piston end of the hydraulic rod 22 is controlled to cause the connecting sleeve 26 installed at the piston end of the hydraulic rod 22 and the U-shaped connecting frame 27 installed on the bottom surface of the connecting sleeve 26 to move downward, and then the pressure roller 28 rotatably installed in the U-shaped connecting frame 27 can be caused to contact with the multi-solid waste-based cementitious materials, and the pressure resistance of the multi-solid waste-based cementitious materials is tested by controlling the pressure output by the hydraulic rod 22, which can simulate the vertical pressure of the vehicle tire on the road surface. This simulation method is closer to the actual traffic load condition, can more accurately evaluate the pressure resistance of the material in the actual road environment, and can simulate the pressure resistance of the material under different vehicle loads; At the same time, the electric slide rail 24 can also be controlled to cause the slider 23 slidably connected to its surface to drive the U-shaped cover 21 to move to any position on the frame 1, and then the hydraulic rod 22 is controlled to drive the pressure roller 28 after the position is changed to apply pressure to the multi-solid waste-based cementitious material, so that the position of the pressure roller 28 relative to the pressure detection of the multi-solid waste-based cementitious material can be arbitrarily adjusted. The position of the pressure roller 28 can be freely adjusted to simulate the actual pressure conditions at different road positions, so as to better study the local pressure resistance performance of the multi-solid waste-based cementitious material in response to complex traffic loads, and comprehensively evaluate the pressure resistance performance of the material at different positions, thereby providing more accurate data support for the application of the material in different areas of the road; At the same time, the hydraulic rod 22 is controlled to control the electric slide rail 24 to drive the slider 23 to move back and forth on the surface of the electric slide rail 24 while causing the pressure roller 28 to apply pressure to the surface of the multi-solid waste-based cementitious material, thereby causing the pressure roller 28 to move back and forth on the multi-solid waste-based cementitious material to perform a dynamic roller compression test, which can well simulate the dynamic pressure that the material is subjected to when a vehicle travels back and forth on the road surface. This simulation method is more in line with actual traffic conditions and can more realistically reflect the compression resistance of the material under actual road conditions compared to static compression tests. For example, on a busy road, frequent passing of vehicles will cause the road surface to become congested. The surface material is subjected to continuous dynamic pressure. The dynamic roller compression test can evaluate the durability of the material under such long-term dynamic pressure. At the same time, the dynamic reciprocating roller compression will put the material in a state of repeated stress, which is helpful to evaluate the fatigue resistance of the multi-solid waste-based cementitious material, the ability to resist deformation, whether stratification occurs, etc. Under the long-term and repeated pressure, the internal structure of the material may gradually be damaged, such as the generation and expansion of microcracks. Through the dynamic roller compression test, the performance changes of the material under different reciprocating times, such as strength attenuation, deformation increase, etc., can be observed, so as to judge whether the material is suitable for use in fields such as roads that bear dynamic loads; When placing the multi-solid waste-based cementitious material, the handle 29 can be manually pulled to cause the carrying plate 25 to slide out from the surface of the frame 1 to one side under the cooperation of the limiting slider 212 and the limiting slide groove 213, and then the multi-solid waste-based cementitious material to be tested can be conveniently placed on the surface of the carrying plate 25. Compared with placing the material in the limited space inside the frame 1, the sliding carrying plate 25 provides a wider operating space, which helps to improve the placement accuracy, making the process of placing the multi-solid waste-based cementitious material more direct and efficient, saving operation time and energy; When the U-shaped connecting frame 27 is forced downward by the hydraulic rod 22, the connecting rod 34 can slide in the L-shaped through groove opened on the surface of the L-shaped guide frame 32. During the downward movement, when the connecting rod 34 slides to the inclined section of the L-shaped guide frame 32 and continues to slide inside it, the connecting rod 34 can push the sliding connection member 33 to slide into the U-shaped connecting frame 27, thereby enabling the U-shaped abutment frame 35 connected to the U-shaped connecting frame 27 to move toward the side close to the multi-solid waste-based gelling material until the pressure roller 28 contacts and presses the surface of the multi-solid waste-based gelling material, and the abutment plate 36 arranged on one side of the U-shaped abutment frame 35 can abut against the side of the multi-solid waste-based gelling material. If the multi-solid waste-based gelling material is deformed due to pressure, the deformed multi-solid waste-based gelling material can press on the abutment plate 36, so that the guide square rod 38 installed on one side of the abutment plate 36 is in the U-shaped abutment frame 35 slides to one side, and simultaneously pushes the clearance sleeve 39 to move along with it, so that the T-shaped marking rod 311 elastically set by the spring 2 310 and slidably connected to the clearance sleeve 39 can slide to one side and leave a mark on the surface of the marking plate 312. This design can monitor the deformation of the multi-solid waste-based cementitious material during static pressure or dynamic rolling in real time and leave an intuitive mark. With the scale line 313 set on the marking plate 312, it is convenient for the tester to directly observe the position and length change of the mark, so as to quickly and intuitively understand the deformation degree of the material during the compression process. Compared with the traditional method of relying on complex electronic sensors and data processing to monitor deformation, this visual marking method is simpler and more direct, and does not require additional instruments and equipment to interpret the data. Even if there is no complex monitoring system on site, it can easily judge the deformation of the material; The T-shaped marking rod 311 is set by the elasticity of the second spring 310 to ensure the accuracy of the marking. When the material is slightly deformed, the abutment plate 36 is stressed, and the sliding of the guide square rod 38 can accurately transmit the displacement, so that the positioning sleeve 39 moves accordingly, and the elastically connected T-shaped marking rod 311 can sensitively follow the movement and leave a mark on the marking plate 312. The elasticity of the second spring 310 can compensate for some tiny mechanical gaps and vibrations, and avoid inaccurate marking due to looseness or errors between mechanical parts. This high-precision deformation recording method is helpful for more detailed research on the deformation characteristics of materials under different pressures, and provides more accurate data support for evaluating performance indicators such as the material's compressive resistance, fatigue resistance, ability to resist deformation, and whether stratification occurs. At the same time, the mark on the marking plate 312 can be used as an important basis for comparing material properties. When testing multi-solid waste-based cementitious materials of different formulations or different batches, the marking conditions of each material can be compared. By comparing the starting position, moving distance and change trend of the mark, the deformation difference of different materials under the same pressure conditions can be intuitively seen, so as to conveniently screen out materials with better performance. This comparison method is simple and easy, does not require complex data analysis software, and is convenient for rapid material performance comparison between laboratories or different testers. At the same time, the marking plate 312 is installed on the surface of the bearing plate 25 in a detachable connection manner through the fixing bolts 314, and the old marking plate 312 can be easily removed and replaced with a new one, thereby ensuring the accuracy and reliability of the material deformation recording by the testing equipment; When the connecting sleeve 26 moves downward, the H-shaped slide rod 41 slidably connected therein can move downward with it, and at the same time, the tooth plate 43 installed at one end of the H-shaped slide rod 41 can be moved downward, and then the gear 47 meshing with the tooth plate 43 can drive the screw rod 44 to rotate, so that the screw block 45 threadedly connected to the surface of the screw rod 44 can slide to one side, so that the screw rod 48 rotatably connected to the surface of the screw block 45 and the fixed support plate 412 rotatably connected to the surface of the screw rod 48 move accordingly, so that the fixed support plate 412 installed on the fixed support plate The pressing plate 413 on one side of the plate 412 moves toward the side close to the multi-solid waste-based cementitious material until the pressing plate 413 is pressed against the side of the multi-solid waste-based cementitious material, which can effectively prevent the material from being displaced during the test. By fixing the pressing plate 413, the material can always be kept in a predetermined position during the test to ensure the accuracy of the test. At the same time, the stable material fixation helps to ensure the safety of the test process and avoids accidental movement of the material under pressure, which may cause damage to the equipment itself and pose a safety threat to the operator. When the screw rod 48 moves to one side under the action of the screw block 45, the gear 49 installed on the surface of the screw rod 48 can rotate the screw rod 48 under the action of the tooth plate 410, and then the screw plate 411 threadedly connected to the surface of the screw rod 48 can move on the surface of the screw rod 48 under the limitation of the sliding connecting plate 414, and then the pressure plate 415 connected to the screw plate 411 can be moved downward, so that the elastic pressure plate 417 elastically connected by the T-bar 416 and the spring 3 418 is pressed against the upper surface of the multi-solid waste-based cementitious material, and can cooperate with the side clamping plate 413 to fix the material from multiple directions. This multi-directional fixing method can more effectively prevent the material from being displaced during the test, further ensure the stability of the material position, and improve the test accuracy; The elastic pressure plate 417 is elastically connected to the spring three 418 via the T-bar 416, and can automatically adjust the pressing force according to the shape of the material surface. When there is a raised portion on the material surface, the spring three 418 will be compressed so that the elastic pressure plate 417 can fit the raised portion. When encountering a recessed portion, the spring three 418 can stretch to ensure that the elastic pressure plate 417 always maintains good contact with the material surface. This adaptive pressing method can better adapt to the irregularities of the material surface and apply pressure evenly.
