Description

Technical Field

[0001] This invention relates to the field of compressive strength testing technology, specifically to an automated concrete compressive strength testing system based on visual recognition. Background Technology

[0002] Concrete compressive strength is an important technical indicator for evaluating concrete quality. New material-related services include testing and measurement of new materials in accordance with relevant standards and certification and accreditation services. Concrete compressive strength testing is widely used in construction, water conservancy, road and bridge, tunnel and other projects. Some laboratories can perform hundreds of concrete water-based compressive strength tests per day.

[0003] Currently, the most common concrete compressive strength testing procedure is as follows: First, the delivered concrete specimens are placed in groups of three on the testing platform, with each specimen bearing a unique code for easy identification. Next, the testing assistant moves the specimens to the testing machine, where the lab technician enters the code on the specimen and begins the test. The lab technician places the specimen under the indenter of the testing machine and begins the test. After the test, the lab technician removes the specimen and places it in a scrap truck, completing one specimen test. During the testing process, pressure needs to be applied to the surface of the concrete specimen to test its compressive strength.

[0004] In existing technologies, when conducting compressive strength tests on concrete blocks, the coding of the soil blocks must first be scanned and verified. During this process, the soil blocks are placed on the conveyor platform manually, and the positions of the labels may become disordered, making it impossible for them to always face the same direction. This affects the efficiency of using conventional scanning and recognition equipment to scan and input the label information on the soil blocks, thus impacting the efficiency of concrete block compressive strength testing. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide an automated concrete compressive strength testing system based on visual recognition to solve the problems mentioned in the background. The invention features a novel structure: conveyor platforms are set on both sides of the testing platform to transport concrete blocks; two clamping stations of the clamping assembly clamp the soil blocks on the two conveyor platforms and alternately feed them onto the testing platform for compressive strength testing. During the movement of the soil blocks from the conveyor platforms to the testing platform, the clamping assembly rotates the soil blocks, while the scanning assembly at the bottom moves synchronously with the clamping assembly and the soil blocks, scanning multiple surfaces of the soil blocks until information is recorded, thereby improving overall testing efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automated concrete compressive strength testing system based on visual recognition, comprising a testing platform, a top frame fixed to the top of the testing platform, and a base plate fixed to the bottom of the testing platform. Two sets of cylinders are fixed inside the top frame, and extrusion plates are fixed to the extended ends of the cylinders. Conveying platforms are provided at both ends of the testing platform, on which concrete blocks are conveyed, and the outlet end of the conveying platform is at a certain distance from the testing platform. A clamping assembly is provided on the top of one side of the testing platform, the clamping assembly including a sliding frame, and a sliding plate slidably connected inside the sliding frame. Two sets of mounting seats are symmetrically arranged on both sides. Two rotating plates are provided at the bottom of the mounting seats. A scanning component is provided at the bottom of the conveyor table. The scanning component includes slide rails. Two slide rails are symmetrically fixed at the bottom of the conveyor table. A scanning plate is slidably installed between the two slide rails. A scanning end is provided on the upper surface of the scanning plate. Limiting plates are symmetrically arranged on the left and right sides of the top of the detection table. Limiting frames are symmetrically arranged on the front and rear sides of the detection table. Insert frames are slidably connected inside the limiting frames. The two ends of the limiting plates protrude from the insert frames. A connecting column is fixed to the back of the detection table. The connecting column is fixedly connected to the top and bottom of the slide frame.

[0007] Furthermore, each of the four sides of the top surface of the testing platform is equipped with a first screw via a bearing seat and a small motor, and the two ends of the limiting plate and the limiting frame are respectively threaded onto the corresponding first screw.

[0008] Furthermore, a feed plate is rotatably mounted on the central surface of the testing platform via a rotating shaft. The testing platform is provided with a feed groove at the bottom of the feed plate. Two sets of first electric push rods are fixed on the top of the base plate, and a support plate is fixed to the extended end of the first electric push rod, and the support plate is in contact with the bottom of the feed plate.

[0009] Furthermore, the clamping assembly also includes a second screw, which is rotatably mounted inside the slide frame via a bearing. The slide plate is threaded onto the second screw, and a motor that drives the second screw to rotate is mounted on the outer end of the slide frame. The mounting seats at both ends of the slide plate correspond to the outlet end of the conveyor table and the top of the inspection table, respectively.

[0010] Furthermore, a connecting frame is provided on the outer surface of the skateboard, and the two ends of the outer side of the connecting frame are fixedly connected to the mounting base. Two sets of fourth electric push rods are fixed at the bottom of the mounting base, and the fourth electric push rods face two directions. A connecting plate is fixed at the extended end of the fourth electric push rod, and the rotating plate is set at the bottom of the connecting plate.

[0011] Furthermore, a drive shaft is rotatably mounted on the top of the mounting base via a bearing seat. The top and bottom of the drive shaft are fixed with protrusions. Vertical plates are slidably sleeved at both ends of the drive shaft. A transmission belt is mounted on the outer side of the vertical plates, and the upper pulley of the transmission belt is sleeved on the drive shaft. The lower pulley of the transmission belt is fixedly connected to the center of the rotating plate.

[0012] Furthermore, a first bevel gear is fixed to one end of the drive shaft, a second bevel gear is vertically meshed with the outer side of the first bevel gear, a shaft is fixed to the back of the second bevel gear, and the shaft is rotatably mounted on the side of the connecting frame through a bearing bracket.

[0013] Furthermore, a drive gear is rotatably mounted on the side of the connecting frame near the slide plate, corresponding to the position of the shaft. A socket is fixed on the outer surface of the drive gear, and a plug plate is fixed on the end of the shaft facing the socket. The plug plate is slidably inserted into the socket from the bottom. A toothed plate is fixed on the top of the slide frame at the drive gear, and the drive gear is meshed with the toothed plate.

[0014] Furthermore, an insertion plate is fixed to the outer side of the tail end of the scanning plate, and a third electric push rod is fixed to the connecting frame at the position corresponding to the insertion plate. The extended end of the third electric push rod is inserted into the insertion plate. A second electric push rod is fixed at equal intervals on the outer surface of the slide plate, and the extended end of the second electric push rod is fixedly connected to the connecting frame.

[0015] Furthermore, the scanning assembly also includes slide rails. Two slide rails are symmetrically fixed at the bottom of the conveyor table. Protruding plates are fixed on both sides of the scanning plate and slide along the inside of the slide rails. Return springs are fixed at equal intervals at the tail end of the slide rails, and the other end of the return springs is fixedly connected to the scanning plate.

[0016] The beneficial effects of this invention are:

[0017] 1. This invention utilizes the rotation of the first screw, and the threaded engagement of the limiting plate and the limiting frame with the first screw allows for simultaneous changes in their positions. After the concrete block is placed on top, both ends of the limiting plate slide within the limiting frame and extend beyond the insertion frame, adjusting the area enclosed between the limiting plate and the limiting frame. This allows for the bottom enclosure of concrete blocks of different sizes. A cylinder drives the extrusion plate to move and extrude pressure on the top of the concrete block to test its compressive strength. During the testing process, the first electric push rod drives the support plate to support the bottom of the delivery plate. After the test is completed, the support plate moves downward, and the delivery plate rotates along the delivery groove via a motor built into the testing platform, tilting and conveying the concrete block onto the support plate. Finally, the block is manually removed, facilitating cleaning of the top of the testing platform and the delivery of the tested concrete block.

[0018] 2. In this invention, the second screw rotates, and the slide plate moves along the inside of the slide frame in cooperation with the second screw. The two clamping stations on the outside of the slide plate alternately clamp the concrete block from the conveyor table and move it to the testing table, and place the concrete block on the testing table, thereby improving the overall testing efficiency.

[0019] 3. During the lifting and lowering process of the mounting base, the insertion of the insert plate and the socket will not be interfered with by the drive gear. When the concrete block is moved at the highest point, the drive gear moves along the bottom of the toothed plate. When the drive gear rotates, the shaft and the second bevel gear rotate synchronously. The first bevel gear meshes with the second bevel gear to drive the drive shaft to rotate. Because of the convex strip on the drive shaft, the transmission belt will synchronously drive the rotating plate to rotate, and then the concrete block clamped in the rotating plate will rotate, so that different sides are corresponding to the scanning end until the location of the label is scanned and the information is recorded. Through the setting of the convex strip on the drive shaft, when the fourth electric push rod drives the connecting plate and the rotating plate to move, the vertical plate slides synchronously along the surface of the drive shaft, which can change the distance between the two sets of connecting plates and rotating plates. It is suitable for soil blocks of different sizes and will not affect the rotation of the rotating plate driven by the transmission belt.

[0020] 4. This invention, through the insertion of the third electric push rod and the insertion plate, synchronously drives the scanning plate to slide along the slide rail, keeping the scanning end aligned with the bottom of the mounting base. Because there is a certain distance between the conveyor table and the detection table, within this distance, the movement of the clamping assembly will cause the concrete block to flip, aligning different sides with the scanning end. The scanning end identifies and records the information on the concrete block, which can improve the efficiency of soil block identification. After scanning is completed, the extended end of the third electric push rod retracts, and the scanning plate returns to the bottom of the conveyor table by the elastic force of the reset spring, facilitating the next use.

[0021] 5. The shaft of the present invention is vertically inserted into the socket via a plug plate, thereby driving the rotation of the gear to drive the rotation of the shaft. The second electric push rod can drive the connecting frame and the clamping positions at both ends to descend, thereby clamping the concrete blocks on a set of conveying platforms respectively, and placing the clamped and identified soil blocks on the other end onto the detection platform. The two sides are alternately processed to improve the overall detection efficiency.

[0022] 6. Compared with the prior art, the present invention sets up conveyor platforms on both sides of the testing platform to transport concrete blocks. The two clamping stations of the clamping component clamp the soil blocks on the two conveyor platforms respectively and alternately feed them into the testing platform for compressive strength testing. During the process of the clamping component moving the soil block from the conveyor platform to the testing platform, it drives the soil block to rotate. The scanning component at the bottom moves synchronously with the clamping component and the soil block to scan multiple surfaces of the soil block until the information is recorded, thereby improving the overall testing efficiency.

[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0036] Please see Figures 1 to 11This invention provides a technical solution: an automated concrete compressive strength testing system based on visual recognition, comprising a testing platform 1, a top frame 12 fixed to the top of the testing platform 1, and a base plate 11 fixed to the bottom of the testing platform 1. Two sets of cylinders 13 are fixed inside the top frame 12, and extrusion plates 14 are fixed to the extended ends of the cylinders 13. Conveying platforms 2 are provided at both ends of the testing platform 1, conveying concrete blocks on the conveying platforms 2, with a certain distance between the outlet end of the conveying platform 2 and the testing platform 1. A clamping assembly 3 is provided on the top of one side of the testing platform 1, the clamping assembly 3 including a sliding frame 31, a sliding plate 33 slidably connected inside the sliding frame 31, two sets of mounting seats 37 symmetrically arranged on the outer side of the sliding plate 33, and two rotating plates 310 provided at the bottom of the mounting seats 37. A scanning component 4 is provided at the bottom of the conveying platform 2, the scanning component 4 including a slide rail 41, and the bottom of the conveying platform 2... Two slide rails 41 are symmetrically fixed, and a scanning plate 43 is slidably installed between the two slide rails 41. A scanning end 46 is provided on the upper surface of the scanning plate 43. Limiting plates 19 are symmetrically provided on the left and right sides of the top of the testing platform 1, and limiting frames 110 are symmetrically provided on the front and rear sides of the testing platform 1. An insert frame 113 is slidably connected inside the limiting frame 110, and the two ends of the limiting plate 19 protrude from the insert frame 113. A connecting column 18 is fixed on the back of the testing platform 1, and the connecting column 18 is fixedly connected to the top and bottom of the slide frame 31. When using the device, concrete blocks are placed equidistantly on the two conveying platforms 2. The clamping components 3 alternately clamp the concrete blocks from the two conveying platforms 2 and move them to the testing platform 1 for compressive strength testing. During the process of the concrete blocks moving from the conveying platform 2 to the testing platform 1, the scanning components 4 scan and record the label information on the concrete blocks, thereby improving the testing efficiency.

[0037] In this embodiment, the four sides of the top surface of the testing platform 1 are rotatably mounted with first screws 111 via bearing seats and small motors. The two ends of the limiting plate 19 and the limiting frame 110 are respectively threaded onto the corresponding first screws 111. A delivery plate 112 is rotatably mounted on the center surface of the testing platform 1 via a rotating shaft. The bottom of the testing platform 1 at the delivery plate 112 is provided with a delivery groove 15. Two sets of first electric push rods 16 are fixed to the top of the bottom plate 11, and a support plate 17 is fixed to the extended end of the first electric push rod 16. The support plate 17 is in contact with the bottom of the delivery plate 112. The first screw 111 is a bidirectional lead screw. Through the rotation of the first screw 111, the limiting plate 19 and the limiting frame 110 are rotatably mounted on the four sides of the top surface of the testing platform 11. The threaded engagement between the positioning frame 110 and the first screw 111 allows for simultaneous changes in the positions of the limiting plate 19 and the limiting frame 110. After the concrete block is placed on top, both ends of the limiting plate 19 slide within the limiting frame 110 and extend through the insert frame 113, adjusting the area enclosed between the limiting plate 19 and the limiting frame 110. This allows for bottom-limiting and enclosing of concrete blocks of different sizes. The cylinder 13 drives the extrusion plate 14 to move and extrude pressure on the top of the concrete block to test its compressive strength. During the test, the first electric push rod 16 drives the support plate 17 to support the bottom of the delivery plate 112. After the test is completed, the support plate 17 moves downward, and the delivery plate 112 moves along the delivery groove 15 via the motor built into the testing platform 1. The concrete block is tilted and conveyed onto the support plate 17 by rotation, and then manually removed for easy cleaning of the top of the testing platform 1 and delivery of the tested concrete block. (The support plate 17 and the delivery plate 112 are made of alloy material and are thickened to maintain their stability.) Because this application uses a two-end loading method, there is some inconvenience in unloading. The delivery plate 112 in this solution is designed to tilt and rotate to facilitate unloading. Since the testing platform 1 also has a limiting plate 19 for clamping the bricks, and the limiting plate 19 is a four-sided enclosure, the conventional sliding ejection method would be limited here. The tilted delivery method used in this solution can prevent the bricks from being subjected to... The limiting plate 19 blocks the debris, which slides out directly from the bottom. As for the debris, it has an auxiliary effect, which can achieve a certain purpose of cleaning debris to reduce the amount of debris on the inspection table 1. As for the degree of cleaning, some tools or manual cleaning will still be needed later. In terms of the cleaning efficiency of the inspection table 1 that has been simply treated and that has not been treated, the solution in this case will definitely make it easier to clean after some large pieces are sent out first by the rotation of the delivery plate 112. Therefore, the cleaning function can be assumed to require manual or mechanical cleaning later. From the perspective of the cleaning effect alone, the delivery plate 112 can play an auxiliary role in cleaning and reduce the time for later cleaning.

[0038] In this embodiment, the clamping assembly 3 further includes a second screw 32. The second screw 32 is rotatably mounted inside the slide frame 31 via a bearing. The slide plate 33 is threaded onto the second screw 32. A motor that drives the second screw 32 to rotate is installed at the outer end of the slide frame 31. The mounting seats 37 at both ends of the slide plate 33 correspond to the outlet end of the conveyor table 2 and the top of the inspection table 1, respectively. A connecting frame 35 is provided on the outer surface of the slide plate 33, and the two outer ends of the connecting frame 35 are fixedly connected to the mounting seats 37. Two sets of fourth electric push rods 38 are fixed at the bottom of the mounting seats 37, and the fourth electric push rods 38 face two directions. A connecting plate 39 is fixed at the extended end of the fourth electric push rod 38. The rotating plate 310 is set at the bottom of the connecting plate 39. When the second screw 32 rotates, the slide plate 33 and the second screw 32 cooperate to move along the inside of the slide frame 31. The two clamping stations on the outer side of the slide plate 33 alternately clamp the concrete block from the conveyor table 2 and move it to the inspection table 1, and place the concrete block on the inspection table 1, thereby improving the overall inspection efficiency.

[0039] In this embodiment, a drive shaft 313 is rotatably mounted on the top of the mounting base 37 via a bearing seat. The top and bottom of the drive shaft 313 are fixed with protrusions 314. Vertical plates 311 are slidably sleeved at both ends of the drive shaft 313. A transmission belt 312 is mounted on the outer side of the vertical plates 311, with the upper pulley of the transmission belt 312 sleeved on the drive shaft 313. The lower pulley of the transmission belt 312 is fixedly connected to the center of the rotating plate 310. A first bevel gear 316 is fixed to one end of the drive shaft 313. A second bevel gear 317 is vertically meshed with the outer side of the first bevel gear 316. A shaft 315 is fixed to the back of the second bevel gear 317. Rod 315 is rotatably mounted on the side of connecting frame 35 via bearing bracket. A drive gear 318 is rotatably mounted on the side of connecting frame 35 near slide plate 33, corresponding to the position of rod 315. A socket 319 is fixed to the outer surface of the drive gear 318. A plate 320 is fixed to the end of rod 315 facing socket 319, and the plate 320 slides into socket 319 from the bottom. A toothed plate 321 is fixed to the top of the drive gear 318 via sliding frame 31, and the drive gear 318 meshes with the toothed plate 321. Rod 315 is vertically inserted into socket 319 via plate 320, thus the rotation of drive gear 318 can drive rod 315... The rotation of 15, via the second electric push rod 34, can drive the connecting frame 35 and the clamping positions at both ends to descend, thereby clamping the concrete blocks on a set of conveyor tables 2 respectively, and placing the already clamped and identified soil blocks on the other end onto the detection table 1. This process is repeated on both sides to improve the overall detection efficiency. During the lifting and lowering of the mounting base 37, the insertion of the insert plate 320 and the socket 319 will not be interfered with by the drive gear 318. When the concrete blocks are moved back to the highest point, the drive gear 318 moves along the bottom of the toothed plate 321. As the drive gear 318 rotates, the shaft 315 and the second bevel gear 317 rotate synchronously. The first bevel gear 316 and the second bevel gear 317 meshes and drives the drive shaft 313 to rotate. Because of the protrusion 314 on the drive shaft 313, the transmission belt 312 will synchronously drive the rotating plate 310 to rotate, and the concrete block clamped in the rotating plate 310 will rotate, so that different faces are corresponding to the scanning end 46 until the location of the label is scanned and the information is recorded. Through the setting of the protrusion 314 on the drive shaft 313, when the fourth electric push rod 38 drives the connecting plate 39 and the rotating plate 310 to move, the vertical plate 311 slides synchronously along the surface of the drive shaft 313, which can change the distance between the two sets of connecting plates 39 and rotating plates 310, which is suitable for soil blocks of different sizes, and will not affect the rotation of the rotating plate 310 driven by the transmission belt 312.

[0040] In this embodiment, a socket plate 45 is fixed to the outer side of the tail end of the scanning plate 43. A third electric push rod 36 is fixed to the connecting frame 35 at the position corresponding to the socket plate 45, and the extended end of the third electric push rod 36 is inserted into the socket plate 45. A second electric push rod 34 is fixed at equal intervals on the outer surface of the slide plate 33, and the extended end of the second electric push rod 34 is fixedly connected to the connecting frame 35. The scanning assembly 4 also includes a slide rail 41. Two slide rails 41 are symmetrically fixed to the bottom of the conveyor table 2. A protruding plate 44 is fixed to both sides of the scanning plate 43, and the protruding plate 44 slides along the inside of the slide rail 41. A return spring 42 is fixed at equal intervals at the tail end of the slide rail 41, and the other end of the return spring 42 is fixedly connected to the scanning plate 43. The socket plate 45 is located on one side of the clamping assembly 3, and both scanning assemblies 4 at the bottom of the two conveyor tables 2 have socket plates 45. When one end of the clamping assembly 3 moves to the top of the conveyor table 2, the third electric push rod 36 is fixed to the outer side of the scanning assembly 43. The extended ends of the three electric push rods 36 are inserted into the insertion plate 45. The second electric push rod 34 drives the mounting base 37 to descend, facilitating the clamping of the concrete block by the connecting plate 39 and the rotating plate 310. Subsequently, the slide plate 33 moves along the sliding frame 31, conveying the concrete block to the testing table 1. During this process, due to the insertion of the third electric push rod 36 into the insertion plate 45, the scanning plate 43 will be simultaneously driven to slide along the slide rail 41, keeping the scanning end 46 aligned with the bottom of the mounting base 37. Furthermore, because there is a certain distance between the conveying table 2 and the testing table 1, within this distance, the movement of the clamping assembly 3 will cause the concrete block to flip, aligning different faces with the scanning end 46. By scanning the information on the concrete block through the scanning end 46, the efficiency of soil block identification can be improved. After scanning is completed, the extended end of the third electric push rod 36 is retracted, and the scanning plate 43 returns to the bottom of the conveying table 2 by the elastic force of the return spring 42, facilitating the next use.

[0041] When using the device, concrete blocks are placed equidistantly on the two conveyor platforms 2. The rotation of the first screw 111 causes the threaded engagement of the limiting plate 19 and the limiting frame 110 with the first screw 111 to simultaneously change their positions. After the concrete block is placed on top, both ends of the limiting plate 19 slide within the limiting frame 110 and extend through the insertion frame 113, adjusting the area enclosed between the limiting plate 19 and the limiting frame 110. This allows for bottom-limiting and enclosing of concrete blocks of different sizes. The cylinder 13 drives the extrusion plate 14 to move, extruding pressure on the top of the concrete block to test its compressive strength. During the test, the first electric push rod 16 drives the support plate 17 to support the bottom of the delivery plate 112. After the test is completed, the support plate 17 moves downwards. The delivery plate 112 rotates along the delivery groove 15 via a motor built into the testing platform 1, tilting and conveying concrete blocks onto the support plate 17. Finally, the blocks are manually removed, facilitating cleaning of the top of the testing platform 1 and the removal of the tested concrete blocks. The shaft 315 is vertically connected to the socket 319 via a plug plate 320, which in turn drives the rotation of the gear 318, causing the shaft 315 to rotate. The second electric push rod 34 lowers the connecting frame 35 and the clamping stations at both ends, clamping concrete blocks on one set of conveying platforms 2 and placing already clamped and identified soil blocks onto the testing platform 1. This alternating operation improves overall testing efficiency. During the lifting and lowering of the mounting base 37, the plug plate 320 connects to the socket 319. It will not be interfered with by the drive gear 318, and when it returns to the highest point and drives the concrete block to move, the drive gear 318 travels along the bottom of the toothed plate 321. The drive gear 318 rotates, and the shaft 315 and the second bevel gear 317 rotate synchronously. The first bevel gear 316 meshes with the second bevel gear 317 to drive the drive shaft 313 to rotate. Because of the protrusion 314 on the drive shaft 313, the transmission belt 312 will synchronously drive the rotating plate 310 to rotate, and then the concrete block clamped in the rotating plate 310 will rotate, so that different faces are corresponding to the scanning end 46 until the location of the label is scanned and the information is recorded. Through the setting of the protrusion 314 on the drive shaft 313, when the fourth electric push rod 38 drives the connecting plate 39 and the rotating plate 310 to move, the vertical plate 3 The 11-axis synchronous sliding mechanism along the drive shaft 313 allows for adjustment of the spacing between the two sets of connecting plates 39 and rotating plates 310, accommodating soil blocks of different sizes without affecting the rotation of the rotating plates 310 driven by the transmission belt 312. This conveys the concrete block onto the testing platform 1. During this process, the insertion of the third electric push rod 36 into the insertion plate 45 synchronously drives the scanning plate 43 to slide along the slide rail 41, maintaining the scanning end 46 aligned with the bottom of the mounting base 37. Because there is a certain distance between the conveying platform 2 and the testing platform 1, within this distance, the movement of the clamping assembly 3 causes the concrete block to flip, aligning different faces with the scanning end 46. The scanning end 46 identifies and records information on the concrete block, improving the efficiency of soil block identification. After scanning is complete...The third electric push rod 36 retracts its extended end, and the scanning plate 43 returns to the bottom of the conveyor table 2 via the spring force of the return spring 42, facilitating the next use. Although existing technologies can use robotic arms for loading and unloading, this solution does not necessarily rely on manual loading and unloading. The initial placement of the material on the conveyor table 2 can also be achieved by additionally setting up a robotic arm. The subsequent removal of the inspected bricks can also be done using a robotic arm gripper. Robotic arm loading and unloading are existing technologies and are not described again in this solution; they can be considered common techniques. The focus of this solution is on the combined process of loading and scanning.
