Description

Technical Field

[0001] This invention relates to the field of concrete testing technology, specifically to an automatic concrete slump testing device. Background Technology

[0002] In the field of concrete construction quality control, slump is a key indicator for measuring the fluidity, cohesiveness and water retention of concrete. Its test results are directly related to the strength, durability and construction pouring effect of the engineering structure, and are one of the core links to ensure the quality of concrete engineering.

[0003] During the use of this device, concrete is first poured into the conical bucket. Then, the concrete inside the conical bucket is stirred evenly using a stirring rod. Next, excess concrete at the top of the conical bucket is scraped off. Then, the conical bucket is slowly lifted upwards, allowing the concrete inside to collapse freely, thus completing the test. During the process of stirring the concrete by moving the stirring rod up and down, due to the small size of the top inlet of the conical bucket, the concrete inside the bucket may not be completely stirred evenly, resulting in a relatively loose concrete and affecting the quality of the concrete test. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic concrete slump testing device to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: The present invention is an automatic concrete slump testing device, comprising a main body, a support frame fixedly connected to the top of the main body, and a recorder fixedly connected inside the support frame. The recorder has an electric actuator on its top, with a push rod fixedly connected to its output end. The side wall of the electric actuator is fixedly connected to the inner wall of the support frame. It also includes: The shrinkage mechanism is installed at the bottom of the main body and is used to mix the concrete. The rotating mechanism is installed inside the main body and is used to rotate when the retraction mechanism moves.

[0006] Furthermore, the main body includes: The lifting assembly is installed on the top of the main body via fasteners and is used to detect the slump of concrete. The fasteners include two support frames 2 that are fixedly connected to the top of the main body, and two sliding blocks are internally threaded to the support frames 2; Telescopic components are fixedly installed on the side wall of the lifting components and are used to extend or retract after the lifting components are moved.

[0007] Furthermore, the shrinkage mechanism includes: Auxiliary components are installed inside the telescopic components and are used to rotate under the push of the telescopic components; The movable component is installed inside the auxiliary component and is used for raising and lowering within the auxiliary component.

[0008] Furthermore, the rotating mechanism includes: A rotating component is installed at the bottom of the movable component to drive the movable component to rotate. The oscillating component is installed at the bottom of the rotating component and is used to oscillate when the rotating component moves.

[0009] Furthermore, the lifting assembly includes a connecting rod 1 fixedly connected to the side wall of the sliding block, and a conical barrel 1 fixedly connected to one end of the two connecting rods 1 that are close to each other; One of the connecting rods is fixedly connected to a conical barrel at the end furthest from the sliding block.

[0010] Furthermore, the telescopic assembly includes a fixing plate fixedly connected to the side wall of one of the sliding blocks, and an electric actuator is fixedly connected to the top of the fixing plate; The output end of the electric actuator is fixedly connected to the connecting rod, and the internal part of the connecting rod is rotatably connected to a telescopic block.

[0011] Furthermore, the auxiliary component includes a connecting block 1 rotatably connected to the outer surface of the telescopic block, and a placement groove is provided at the bottom of the connecting block 1; The side wall of the placement slot is provided with a threaded groove, and the top and bottom of the threaded groove are provided with inclined grooves.

[0012] Furthermore, a spring is fixedly connected to the inner wall of the placement groove, a protrusion is fixedly connected to the bottom of the spring, and a movable block is fixedly connected to the outer surface of the protrusion. The outer surface of the movable block is slidably connected to the inner wall of the placement groove.

[0013] Furthermore, the rotating assembly includes an elastic plate fixedly connected to the bottom of the protrusion, and an annular groove is provided on the bottom of the elastic plate; The annular groove has a sliding connection to a second movable block, and the bottom of the second movable block is fixedly connected to a sliding plate. The bottom of the telescopic block is slidably connected to the top of the elastic plate, and the outer surface of the sliding plate is slidably connected to the inside of the fixed plate.

[0014] Furthermore, the swing assembly includes a fixed rod fixedly connected to the bottom of the elastic plate, and a connecting block two is fixedly connected to the bottom of the fixed rod; A sleeve is slidably connected to the outer surface of connecting block two, and spring two is fixedly connected to the inner wall of the sleeve; The end of the second spring away from the sleeve is fixedly connected to the outer surface of the fixed rod.

[0015] The present invention has the following beneficial effects: 1. In this invention, when the protrusion moves into the placement groove, it pushes the spring to contract under thrust. As the protrusion moves into the placement groove, the elastic plate changes from a circular state to an internally convex state, and the fixing rod at the bottom of the elastic plate becomes inclined. When the elastic plate rotates, the inclined state of the fixing rod allows for better and more uniform mixing of the concrete inside the conical bucket. This reduces the occurrence of voids on the outermost surface of the concrete due to uneven mixing on one side of the conical bucket when mixing the concrete through the fixing rod, making the overall concrete conform more closely to the actual situation and improving the quality of concrete testing.

[0016] 2. In this invention, when the second movable block is pulled by the protrusion, the side of the elastic plate will be restricted by the second movable block and will not move up or down. This causes the elastic plate to become convex as it moves upward. During the process of the elastic plate becoming convex, its side will contract, thereby restricting the elastic plate by pulling the sliding plate from the inside of the fixed plate to the outside through the second movable block. This reduces the situation where, during the process of the protrusion pulling the elastic plate to make it convex, the elastic plate will move upward due to the low friction between the elastic plate and the inner wall of the fixed plate, thus preventing the elastic plate from becoming convex. This makes the operation of the elastic plate more stable and improves the overall efficiency of the device during operation.

[0017] 3. In this invention, during the resetting process of the elastic plate, the fixing rod at its bottom will pull the sleeve to reset via spring two. Since the fixing rod and the sleeve are connected by spring two, the sleeve will swing back and forth on the outer surface of the fixing rod during resetting, thereby throwing the concrete on the outer surface of the sleeve downwards. This reduces the situation where, after the concrete inside the conical bucket is mixed, some concrete adheres to the outer surface of the sleeve during the upward resetting process, causing some concrete adhering to the outer surface of the sleeve to drip downwards during concrete testing, affecting subsequent test results. This avoids external influences on the concrete during testing and further improves the quality of concrete testing.

[0018] 4. In this invention, during the process of the fixed rod pulling the spring two, the spring two will undergo a certain deformation. After the spring two pulls the sleeve to reset, the spring two will swing the sleeve due to the deformation reset. During the swinging of the sleeve, the connecting block two will slide inside the sleeve. Since one side of the connecting block two is fixedly connected to the fixed rod, the sleeve can be restricted by the connecting block two when swinging. When the sleeve is restricted, it can reduce the collision with the side wall of the conical barrel two due to excessive shaking of the sleeve, which would lead to a decrease in the overall stability of the device. This allows the sleeve to shake slightly, further enhancing the overall stability of the device.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1-9 As shown, the present invention is an automatic concrete slump testing device, including a main body 1, a support frame 101 fixedly connected to the top of the main body 1, and a recorder 102 fixedly connected inside the support frame 101. The recorder 102 has an electric actuator 103 on its top, and a push rod 104 is fixedly connected to the output end of the electric actuator 103. The side wall of the electric actuator 103 is fixedly connected to the inner wall of the support frame 101. It also includes: Shrinkage mechanism 2 is installed at the bottom of the main body 1 and is used to mix concrete. Rotating mechanism 3 is installed inside the main body 1 and is used to rotate when the retraction mechanism 2 moves.

[0025] Entity 1 includes: The lifting assembly 11 is installed on the top of the main body 1 by means of a fastener and is used to detect the slump of concrete. The fasteners include two support frames 111 fixedly connected to the top of the main body 1, and two sliding blocks 112 are internally threaded to the support frames 111. Telescopic component 12 is fixedly installed on the side wall of lifting component 11 and is used to extend or retract after lifting component 11 moves.

[0026] The shrinkage mechanism 2 includes: Auxiliary component 21 is installed inside the telescopic component 12 and is used to rotate under the push of the telescopic component 12; The movable component 22 is installed inside the auxiliary component 21 and is used for lifting and lowering within the auxiliary component 21.

[0027] Rotating mechanism 3 includes: Rotating component 31 is installed at the bottom of moving component 22 and is used to drive moving component 22 to rotate; The swing assembly 32 is installed at the bottom of the rotating assembly 31 and is used to swing when the rotating assembly 31 moves.

[0028] The lifting assembly 11 includes a connecting rod 113 fixedly connected to the side wall of the sliding block 112, and a conical barrel 114 fixedly connected to one end of the two connecting rods 113 that are close to each other. One of the connecting rods 113 is fixedly connected to a conical barrel 115 at the end away from the sliding block 112. As the sliding block 112 moves downward, it will drive the conical barrel 114 connected to the connecting rod 113 on its side wall to move downward, so that the bottom of the conical barrel 114 fits against the top of the main body 1. Then, the other sliding block 112 will drive the conical barrel 115 connected to the connecting rod 113 on its side wall to move downward, so that the bottom of the conical barrel 115 fits against the top of the conical barrel 114.

[0029] The telescopic assembly 12 includes a fixed plate 121 fixedly connected to the side wall of one of the sliding blocks 112, and an electric push rod 122 fixedly connected to the top of the fixed plate 121. The output end of the electric actuator 122 is fixedly connected to the connecting rod 123. The connecting rod 123 is rotatably connected to the telescopic block 124. After the fixed plate 121 moves downward and pushes the sleeve 323 downward into the conical barrel 114, the electric actuator 122 will extend and retract. When the electric actuator 122 extends and retracts, its output end will push the connecting rod 123 to move. During the movement of the connecting rod 123, the telescopic block 124 and the elastic plate 311 will rotate.

[0030] The auxiliary component 21 includes a connecting block 211 rotatably connected to the outer surface of the telescopic block 124, and a placement groove 212 is provided at the bottom of the connecting block 211. The side wall of the placement groove 212 is provided with a threaded groove 213, and the top and bottom of the threaded groove 213 are provided with inclined grooves 214. After the elastic plate 311 stops rotating, the moving block 223 located inside the threaded groove 213 will stop moving upward, so that the protrusion 222 cannot move upward inside the placement groove 212.

[0031] A spring 221 is fixedly connected to the inner wall of the placement groove 212, a protrusion 222 is fixedly connected to the bottom of the spring 221, and a movable block 223 is fixedly connected to the outer surface of the protrusion 222. The outer surface of the movable block 223 is slidably connected to the inner wall of the placement groove 212. As the protrusion 222 moves into the placement groove 212, it will drive the elastic plate 311 at its bottom to move upward.

[0032] The rotating assembly 31 includes an elastic plate 311 fixedly connected to the bottom of the protrusion 222, and an annular groove 312 is provided at the bottom of the elastic plate 311. The annular groove 312 is slidably connected to a second movable block 313, and the bottom of the second movable block 313 is fixedly connected to a sliding plate 314. The bottom of the telescopic block 124 is slidably connected to the top of the elastic plate 311, and the outer surface of the sliding plate 314 is slidably connected to the inside of the fixed plate 121. When the moving block 313 is pulled by the protrusion 222, its side will be restricted and fixed by the moving block 313, thereby causing the center of the elastic plate 311 to move upward and the elastic plate 311 as a whole to become convex.

[0033] The swing assembly 32 includes a fixed rod 321 fixedly connected to the bottom of the elastic plate 311, and a connecting block 322 is fixedly connected to the bottom of the fixed rod 321. A sleeve 323 is slidably connected to the outer surface of connecting block 2 322, and a spring 2 324 is fixedly connected to the inner wall of sleeve 323; Among them, the end of the second spring 324 away from the sleeve 323 is fixedly connected to the outer surface of the fixed rod 321. During the process of the fixed rod 321 pulling the second spring 324, the second spring 324 will undergo a certain deformation. After the second spring 324 pulls the sleeve 323 to reset, the second spring 324 will swing the sleeve 323 due to the deformation reset.

[0034] In use, firstly, the two connecting rods 113 connected to the conical barrel 114 are moved downwards on the support frame 111 via the sliding block 112. As the sliding block 112 moves downwards, it causes the conical barrel 114 connected to the connecting rods 113 on its sidewall to move downwards, thus bringing the bottom of the conical barrel 114 into contact with the top of the main body 1. Then, the other sliding block 112 causes the conical barrel 115 connected to the connecting rod 113 on its sidewall to move downwards. When the conical barrel 115 moves downwards, it will contact the conical barrel 114... The top of cone 14 is attached to the cone, and then the mixed concrete is poured into the cone 114 through the cone 2 115. At the same time, the sliding block 112 connected to the fixed plate 121 is activated, causing the fixed plate 121 to slide up and down. When the fixed plate 121 slides down, it will drive the bottom sleeve 323 to move into the cone 114, so that the sleeve 323 is inserted into the concrete inside the cone 114. When the fixed plate 121 slides up, it will adjust the sleeve 323 to make it fit with the cone 114. Separation occurs as the fixed plate 121 slides up and down, allowing the sleeve 323 to insert and mix the concrete inside the conical barrel 114. This ensures a more even distribution of the concrete within the conical barrel 114 as the sleeve 323 moves up and down. Subsequently, as the sliding block 112 and the fixed plate 121 move upwards synchronously, they drive the connected conical barrel 115 and sleeve 323 to move synchronously. At that time, the electric actuator 103 on the support frame 101 pushes the push rod 104 to remove the concrete on the top of the conical barrel 114. Then, the sliding block 112 drives the conical barrel 114 to move slowly and uniformly upward through the connecting rod 113. When the conical barrel 114 moves upward, the concrete inside it loses its restraint and collapses. The recorder 102 on the support frame 101 captures the collapse state of the concrete. Then, the system compares the image with the height of the conical barrel 114 to complete the slump detection.

[0035] After the fixed plate 121 moves downward, pushing the sleeve 323 downward into the conical barrel 114, the electric actuator 122 will extend and retract. During this extension and retraction, the output end of the electric actuator 122 will push the connecting rod 123 to move. As the connecting rod 123 moves, it will cause the telescopic block 124 and the elastic plate 311 to rotate. During the rotation of the elastic plate 311, the protrusion 222 on its top will cause the moving block 223 to rotate. When the moving block 223 rotates, it is restricted by the threaded groove 213 and moves upward, thus causing the protrusion 222 to move into the placement groove 212. As the protrusion 222 moves into the placement groove 212, it will push... The spring 221 is pushed and contracts. When the protrusion 222 moves into the placement groove 212, the elastic plate 311 changes from a circular plate state to an internally convex state. At the same time, the fixing rod 321 at the bottom of the elastic plate 311 becomes inclined. When the elastic plate 311 rotates, the inclined state of the fixing rod 321 can better and more evenly mix the concrete inside the conical barrel 114. This reduces the situation where the sides of the conical barrel 114 are not mixed and voids appear on the outermost edge of the concrete when the concrete inside the conical barrel 114 is mixed by the fixing rod 321. This makes the concrete more in line with the actual situation and improves the quality of concrete testing.

[0036] As the protrusion 222 moves into the placement groove 212, it causes the elastic plate 311 at its bottom to move upward. During this upward movement, because the bottom of the elastic plate 311 is slidably connected to the second movable block 313 via the annular groove 312, when the second movable block 313 is pulled by the protrusion 222, the side of the elastic plate 311 is restricted by the second movable block 313 and contracts, preventing it from moving up or down. This causes the elastic plate 311 to become convex as it moves upward. During this process of the elastic plate 311 becoming convex… In the middle, its side will retract, thereby pulling the sliding plate 314 from the inside of the fixed plate 121 outward through the moving block 213 to restrict the elastic plate 311. This reduces the situation that occurs when the protrusion 222 pulls the elastic plate 311 to make it bulge as a whole, and the elastic plate 311 moves upward as a whole due to the small friction between the elastic plate 311 and the inner wall of the fixed plate 121, thus preventing the elastic plate 311 from becoming bulging. This makes the operation of the elastic plate 311 more stable and improves the overall efficiency of the device during operation.

[0037] After the elastic plate 311 stops rotating, the moving block 223 located inside the threaded groove 213 will stop moving upward, thus preventing the protrusion 222 from moving upward inside the placement groove 212. At this time, since the thrust generated by the upward movement of the protrusion 222 on the spring 221 disappears, the force generated by the contraction of the spring 221 will exert a downward thrust on the protrusion 222, causing the spring 221 to reset. When the protrusion 222 moves downward under the thrust, it will drive the moving block 223 to slide downward inside the inclined groove 214, thus making the elastic plate 311 flat. During the reset process of the elastic plate 311, the fixing rod 321 at its bottom will be reset by the spring 223. 4. Pull the sleeve 323 to reset. Since the fixed rod 321 and the sleeve 323 are connected by the second spring 324, the sleeve 323 will swing back and forth on the outer surface of the fixed rod 321 when it resets. This will cause the concrete on the outer surface of the sleeve 323 to fall downwards. This reduces the situation where some concrete adheres to the outer surface of the sleeve 323 after the concrete inside the conical bucket 114 is mixed and the sleeve 323 moves upwards to reset. This would cause some concrete adhering to the outer surface of the sleeve 323 to drip downwards during concrete testing, affecting the subsequent test results. This avoids external influences on the concrete during testing and further improves the quality of concrete testing.

[0038] When the elastic plate 311 resets, it pulls the fixing rod 321 to reset. During the reset process of the fixing rod 321, it applies a pulling force to the spring 324, thereby pulling the sleeve 323 to reset. During the process of the fixing rod 321 pulling the spring 324, the spring 324 will undergo a certain deformation. After the spring 324 pulls the sleeve 323 to reset, the spring 324 will swing the sleeve 323 due to the deformation reset. During the swing of the sleeve 323, the connecting block 322 will slide inside the sleeve 323. Since one side of the connecting block 322 is fixedly connected to the fixing rod 321, the sleeve 323 can be restricted by the connecting block 322 when swinging. When the sleeve 323 is restricted, it can reduce the collision of the sleeve 323 with the side wall of the conical barrel 115 due to excessive shaking, which would lead to a decrease in the overall stability of the device. This allows the sleeve 323 to shake slightly, further enhancing the overall stability of the device.
