Description

Technical Field

[0001] This utility model relates to the field of concrete strength testing technology, and in particular to a device for testing the strength of manufactured sand concrete. Background Technology

[0002] Mechanized sand concrete is widely used in various building structures. Its strength is directly related to the safety and stability of the structure. By using a strength testing device, the actual strength of the concrete can be accurately measured, thereby assessing whether the structure can withstand the design load and ensuring that the building will not have safety hazards due to insufficient concrete strength during its service life.

[0003] A search revealed Chinese patent publication number CN217237513U, which discloses a strength testing device for manufactured sand concrete. The device includes a top plate and a bottom plate. A concrete block to be tested is placed on the bottom plate. A testing assembly is fixedly connected to the lower surface of the top plate. The testing assembly includes a first motor, a first push rod, a limiting frame, a drive block, a limiting block, a detection rod, and a detection block. The first motor is fixedly connected to the lower surface of the top plate, with its output end pointing downwards and connected to the first push rod. The first push rod is vertically positioned, and a limiting frame is fixedly connected to its bottom. The limiting frame is vertical. The device features a rectangular frame structure with a driving block inside the limiting frame. The driving block is a horizontally arranged cylindrical or cuboid structure. The two sides of the driving block contact the inner wall of the limiting frame, and the two ends of the driving block extend to the outside of the limiting frame. Limiting blocks that can retract into the driving block are also connected to the two sides of the driving block. This utility model has the advantage of testing the strength of concrete blocks in different ways. However, in actual use, the device will damage the test specimen to achieve the testing purpose, which requires the preparation of new specimens for other tests, resulting in resource waste and reduced work efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a device for testing the strength of manufactured sand concrete, which aims to improve the problem in the prior art that the test specimens need to be damaged and re-prepared for other tests, thus reducing work efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a device for testing the strength of manufactured sand concrete, comprising a base, with support plates fixedly connected to both the left and right sides of the base, a sliding groove being provided on each adjacent side of the two support plates, a hydraulic rod being fixedly connected to the top of the inner side of each sliding groove, a sliding block being fixedly connected to one end of each hydraulic rod, a common horizontal plate being fixedly connected to each adjacent side of the two sliding blocks, a moving groove being provided at the bottom of the horizontal plate, a telescopic rod being fixedly connected to the left side of the inner side of the moving groove, a moving block being fixedly connected to one end of the telescopic rod, a pressure plate being fixedly connected to the bottom of the moving block, a U-shaped frame being fixedly connected to the bottom right side of the horizontal plate, a displacement sensor being fixedly connected to the left side of the U-shaped frame, and clamping mechanisms being provided on the front and rear sides of the support plates.

[0006] The above technical solution involves first placing the manufactured sand concrete specimen stably on the base. A hydraulic rod extends and retracts to push a sliding block fixedly connected to it, allowing the sliding block to move smoothly up and down within a sliding groove. This, in turn, causes a horizontal plate, fixedly connected to the adjacent sides of two sliding blocks, to rise and fall, adjusting the distance between the horizontal plate and the base. This brings the entire pressure testing component closer to the specimen. Once the horizontal plate is in the appropriate position, a telescopic rod fixedly connected to the left side of the moving groove at the bottom of the horizontal plate activates. The telescopic rod extends and retracts to push the moving block left and right within the moving groove. The movement of the moving block causes the pressure plate to move, thus precisely applying pressure to the concrete specimen. During the pressurization process, a U-shaped frame fixedly connected to the right side of the bottom of the horizontal plate and a displacement sensor fixedly connected to the left side of the U-shaped frame begin to operate. The displacement sensor monitors the displacement changes of the pressure plate during the pressurization process and feeds this data back to the operator to determine whether the strength of the manufactured sand concrete specimen meets the standards.

[0007] As a further description of the above technical solution:

[0008] The clamping mechanism includes multiple grooves, which are respectively opened on the front and rear sides of the corresponding support plates. Each groove is slidably connected to a corresponding support frame. Multiple limiting holes are equidistantly opened at both ends of the opposite sides of the two support plates. Limiting bolts are rotatably connected to the left and right ends of the two support frames. One end of each limiting bolt passes through the corresponding limiting hole in sequence. A second sliding groove is opened on an adjacent side of the two support frames. A corresponding clamping plate is slidably connected at both ends of the two second sliding grooves. Multiple fixing holes are equidistantly opened on the opposite sides of the two support frames. A corresponding limiter is slidably connected to the front and rear ends of the two clamping plates.

[0009] The above technical solution involves the following steps when using a manufactured sand concrete strength testing device: First, the specimen must be fixed. The support frame is slid into the groove, and its position within the groove can be adjusted according to the specimen's height. Once the support frame is at the appropriate height, the limiting bolts are rotated so that one end passes through the corresponding limiting holes, fixing the support frame at the required height and preventing movement during testing. Next, the clamping plate is slid to adjust its position according to the specimen's size. When the clamping plate is adjusted to securely hold the specimen, the limiter is pushed to insert into the corresponding fixing hole, thus fixing the clamping plate and tightly holding the specimen.

[0010] As a further description of the above technical solution:

[0011] A switch is fixedly connected to the top front side of the base, and the switch is electrically connected to the hydraulic rod and the telescopic rod respectively.

[0012] Through the above technical solution: the switch controls the start, stop, and adjustment of the extension and retraction of the hydraulic rod and telescopic rod, thereby controlling the lifting and lowering of the horizontal plate and the horizontal movement of the pressure plate.

[0013] As a further description of the above technical solution:

[0014] Both sliding grooves have sliding grooves on their front and rear sides, and both sliding blocks have sliders fixedly connected to their front and rear sides. The sliders are slidably connected to the interior of their respective sliding grooves.

[0015] The above technical solution allows the slider to slide within the groove, guiding and limiting the sliding block, ensuring that the sliding block moves smoothly up and down within the groove.

[0016] As a further description of the above technical solution:

[0017] Each of the two clamping plates is fixedly connected to a pad on one of its adjacent sides, and each of the two pads is fixedly connected to a plurality of rubber pads at equal intervals on one of its adjacent sides.

[0018] Through the above technical solution: the pad can increase the contact area between the clamping plate and the specimen, making the clamping force distribution more uniform, while the rubber pad has good elasticity and friction, which can prevent the specimen from being damaged during the clamping process.

[0019] As a further description of the above technical solution:

[0020] The base has four fixed support feet at its bottom corners, and each of the support feet has a soft pad fixed to its bottom.

[0021] Through the above technical solution: the support feet fixedly connected at the four corners of the base support the entire detection device, keeping the device in a stable standing position, while the soft pads fixedly connected at the bottom of the support feet can increase the friction with the ground.

[0022] As a further description of the above technical solution:

[0023] Each of the limiting bolts has a washer slidably connected to its outer wall, and one side of each washer is in contact with one side of the corresponding support plate.

[0024] The above technical solution allows the shims to increase the contact area between the limit bolts and the support plate when tightening the limit bolts to fix the support frame, thus making the pressure distribution more uniform.

[0025] As a further description of the above technical solution:

[0026] The two sliding blocks are respectively slidably connected inside the corresponding sliding groove, and the size of the sliding blocks matches that of the sliding groove.

[0027] The above technical solution provides a track and support points for the horizontal plate to move up and down. By cooperating with hydraulic rods, the lifting height of the horizontal plate can be precisely controlled.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the test specimen is supported by a base, the hydraulic rod pushes the sliding block to drive the horizontal plate to rise and fall, the telescopic rod pushes the moving block to drive the pressure plate to apply pressure, and the displacement sensor monitors the displacement, thus realizing the accurate detection of the strength of the manufactured sand concrete test specimen. The operation is simple and the work efficiency is improved.

[0030] 2. In this utility model, by sliding the support frame into the groove and adjusting its position according to the height of the specimen, fixing it with a limiting bolt passing through the limiting hole, and then sliding the clamping plate according to the size of the specimen and fixing it with a limiter inserted into the fixing hole, a firm fixation of specimens of different sizes is achieved, ensuring the stability of the specimen during testing and improving the accuracy of the test results.

[0038] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a device for testing the strength of manufactured sand concrete, comprising a base 1, with support plates 3 fixedly connected to both the left and right sides of the base 1. Each of the two support plates 3 has a sliding groove 4 on an adjacent side, providing a track for the sliding block 6 to move up and down. Hydraulic rods 5 are fixedly connected to the top inner sides of each of the two sliding grooves 4. The hydraulic rods 5 extend and retract to push the sliding block 6 up and down. A sliding block 6 is fixedly connected to one end of each of the two hydraulic rods 5. The sliding block 6 connects the hydraulic rods 5 and a horizontal plate 7 and moves within the sliding groove 4. A single horizontal plate 7 is fixedly connected to an adjacent side of each of the two sliding blocks 6. The horizontal plate 7 carries a pressure component and moves with the sliding block 6. A moving groove 8 is provided at the bottom of the horizontal plate 7, providing space for the moving block 10 to move left and right. A telescopic rod 9 is fixedly connected to the left side inside the moving groove 8. The telescopic rod 9 extends and retracts to push the moving block 10 left and right. One end of the telescopic rod 9 is fixedly connected to... A movable block 10 is connected to the telescopic rod 9 and the pressure plate 11 and moves within the movable groove 8. The pressure plate 11 is fixedly connected to the bottom of the movable block 10 and applies pressure to the manufactured sand concrete specimen. A U-shaped frame 12 is fixedly connected to the bottom right side of the horizontal plate 7 and is used to install a displacement sensor 13. A displacement sensor 13 is fixedly connected to the left side of the U-shaped frame 12 and is used to monitor the displacement change of the pressure plate 11. A clamping mechanism 2 is provided on the front and rear sides of the support plate 3 and is used to fix the manufactured sand concrete specimen. Slide grooves 15 are opened on the front and rear sides of the interior of the two sliding grooves 4. The slide grooves 15 provide sliding tracks for the sliders 16. Slides 16 are fixedly connected to the front and rear sides of the two sliding blocks 6. The sliders 16 cooperate with the slide grooves 15 to make the sliding blocks 6 move smoothly. Multiple sliders 16 are slidably connected to the interior of the corresponding slide grooves 15 to ensure that the sliding blocks 6 run stably within the sliding grooves 4.

[0040] Specifically, the manufactured sand concrete specimen is first placed stably on the base 1. The hydraulic rod 5 extends and retracts to push the sliding block 6 fixedly connected to it, allowing the sliding block 6 to move smoothly up and down within the sliding groove 4. This, in turn, drives the horizontal plate 7, which is fixedly connected to the adjacent side of the two sliding blocks 6, to lift and lower, thereby adjusting the distance between the horizontal plate 7 and the base 1, bringing the entire pressure testing component closer to the specimen. When the horizontal plate 7 moves to the appropriate position, the telescopic rod 9 fixedly connected to the left side of the moving groove 8 at the bottom of the horizontal plate 7 takes effect. The telescopic rod 9 extends and retracts to push the moving block 10 to move left and right within the moving groove 8. The movement of block 10 will drive the pressure plate 11 to move, thereby applying pressure precisely to the concrete specimen. During the pressurization process, the U-shaped frame 12 fixedly connected to the bottom right side of the horizontal plate 7 and the displacement sensor 13 fixedly connected to the left side of the U-shaped frame 12 start to work. The displacement sensor 13 can monitor the displacement change of the pressure plate 11 during the pressurization process of the specimen in real time and feed back these data to the operator to determine whether the strength of the manufactured sand concrete specimen meets the standard. The slider 16 slides in the slide groove 15, which can guide and limit the sliding block 6, ensuring that the sliding block 6 moves up and down smoothly in the slide groove 4.

[0041] Reference Figure 1 , Figure 4 and Figure 5The clamping mechanism 2 includes multiple grooves 201, which are respectively formed on the front and rear sides of the corresponding support plates 3, allowing the support frame 202 to find a suitable installation position on the support plate 3. The support frame 202 is slidably connected inside each of the multiple grooves 201, and can slide up and down within the grooves 201 to accommodate specimens of different heights. Multiple limiting holes 203 are equidistantly formed at both ends of the opposite sides of the two support plates 3. The limiting holes 203 are used to fix the height of the support frame 202 with limiting bolts 204. Limiting bolts 204 are rotatably connected to the left and right ends of the two support frames 202. Rotating the limiting bolts 204 locks the height of the support frame 202. One end of each limiting bolt 204 passes through a corresponding limiting hole 203, thereby fixing the support frame 202 at the required height. Sliding grooves 205 are formed on adjacent sides of the two support frames 202. The second sliding groove 205 provides a track for the clamping plate 206 to slide left and right. The two ends of the two sliding grooves 205 are slidably connected to the corresponding clamping plates 206. The clamping plates 206 can move within the sliding grooves 205 to accommodate specimens of different sizes. Multiple fixing holes 207 are equidistantly opened on the opposite sides of the two support frames 202. The fixing holes 207 are used to cooperate with the limiters 208 to fix the position of the clamping plates 206. The front and rear ends of the two clamping plates 206 are slidably connected to the corresponding limiters 208. Pushing the limiters 208 into the fixing holes 207 can lock the position of the clamping plates 206. The outer walls of the multiple limit bolts 204 are slidably connected to the washers 21. The washers 21 increase the contact area between the limit bolts 204 and the support plates 3. One side of the multiple washers 21 is in contact with one side of the corresponding support plate 3 to prevent the surface of the support plate 3 from being damaged due to excessive local pressure, and at the same time enhance the stability of the connection.

[0042] Specifically, when using the manufactured sand concrete strength testing device, the specimen must first be fixed. The support frame 202 is slid into the groove 201. The position of the support frame 202 in the groove 201 can be adjusted according to the height of the specimen. After the support frame 202 is adjusted to a suitable height, the limiting bolt 204 is rotated so that one end passes through the corresponding limiting hole 203 in sequence, fixing the support frame 202 at the required height to prevent it from moving during the testing process. Then, according to the size of the specimen, the position of the clamping plate 206 is adjusted by sliding it. When the clamping plate 206 is adjusted to a position that can firmly clamp the specimen, the limiter 208 is pushed to insert into the corresponding fixing hole 207, thereby fixing the clamping plate 206 and tightly clamping the specimen. When tightening the limiting bolt 204 to fix the support frame 202, the shim 21 can increase the contact area between the limiting bolt 204 and the support plate 3, making the pressure distribution more uniform.

[0043] Reference Figure 1 , Figure 3 and Figure 4A switch 14 is fixedly connected to the top front side of the base 1. The switch 14 is used by the operator to conveniently control the operation of the entire device. The switch 14 is electrically connected to the hydraulic rod 5 and the telescopic rod 9 respectively. The operator can start and stop the hydraulic rod 5 and the telescopic rod 9 and adjust their extension and retraction actions by operating the switch 14. A pad 17 is fixedly connected to each adjacent side of the two clamping plates 206. The pad 17 can increase the contact area between the clamping plate 206 and the specimen, making the clamping force distribution more uniform. Multiple rubber pads 18 are fixedly connected at equal intervals to each adjacent side of the two pads 17. The rubber pads 18 have good elasticity and friction, which can prevent the specimen from being damaged during clamping and enhance the stability of clamping, ensuring that the specimen will not be displaced during testing. Support feet 19 are fixedly connected to the four corners of the bottom of the base 1. The support feet 19 support the entire detection device, so that the device can be placed stably on the ground. Soft pads 20 are fixedly connected to the bottom of the multiple support feet 19. The soft pads 20 can increase the friction with the ground, prevent the device from sliding during operation, and also play a shock absorption role, reducing the impact of external vibration on the detection results and ensuring the accuracy of the detection. Two sliding blocks 6 are slidably connected to the inside of the corresponding sliding grooves 4, providing guidance and support for the up and down movement of the horizontal plate 7. The size of the sliding blocks 6 matches that of the sliding grooves 4, ensuring that the sliding blocks 6 move smoothly in the sliding grooves 4, thereby ensuring the stability and reliability of the lifting process of the horizontal plate 7.

[0044] Specifically, switch 14 controls the start, stop, and adjustment of the extension and retraction of hydraulic rod 5 and telescopic rod 9, thereby controlling the lifting and lowering of horizontal plate 7 and the horizontal movement of pressure plate 11. Pad 17 increases the contact area between clamping plate 206 and specimen, making the clamping force distribution more uniform. Rubber pad 18 has good elasticity and friction, which can prevent the specimen from being damaged during clamping. Support feet 19 fixedly connected at the four corners of the bottom of base 1 support the entire testing device, keeping the device in a stable standing position. Soft pads 20 fixedly connected at the bottom of support feet 19 can increase friction with the ground, providing a track and support point for the horizontal plate 7 to move up and down. In conjunction with hydraulic rod 5, the lifting and lowering height of horizontal plate 7 can be precisely controlled.

[0045] Working principle: When using this equipment, the manufactured sand concrete specimen is first placed stably on the base 1. The hydraulic rod 5 pushes the sliding block 6 fixedly connected to it through extension and retraction, allowing the sliding block 6 to move smoothly up and down within the sliding groove 4. This, in turn, drives the horizontal plate 7, which is fixedly connected to the adjacent side of the two sliding blocks 6, to lift and lower, thereby adjusting the distance between the horizontal plate 7 and the base 1, bringing the entire pressure testing component closer to the specimen. When the horizontal plate 7 moves to the appropriate position, the telescopic rod 9 fixedly connected to the left side inside the moving groove 8 at the bottom of the horizontal plate 7 takes effect. The telescopic rod 9 pushes the moving block 10 to move left and right within the moving groove 8 through extension and retraction. The movement of the moving block 10 drives the pressure plate 11 to move, thereby accurately applying pressure to the concrete specimen. During the pressurization process, the U-shaped frame 12 fixedly connected to the bottom right side of the horizontal plate 7 and the displacement sensor 13 fixedly connected to the left side of the U-shaped frame 12 begin to work. The device 13 can monitor the displacement changes of the pressure plate 11 during the pressurization process of the specimen in real time and feed back these data to the operator to determine whether the strength of the manufactured sand concrete specimen meets the standard. When using the manufactured sand concrete strength testing device, the specimen must be fixed first. The support frame 202 is slid into the groove 201. The position of the support frame 202 in the groove 201 can be adjusted according to the height of the specimen. After the support frame 202 is adjusted to a suitable height, the limiting bolt 204 is rotated so that one end passes through the corresponding limiting hole 203 in sequence to fix the support frame 202 at the required height and prevent it from moving during the test. Then, according to the size of the specimen, the clamping plate 206 is slid to adjust its position. When the clamping plate 206 is adjusted to a position that can firmly clamp the specimen, the limiter 208 is pushed to insert into the corresponding fixing hole 207, thereby fixing the clamping plate 206 and clamping the specimen.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
