Description

Technical Field

[0001] This utility model relates to the field of slump testing technology, and in particular to a novel concrete slump testing device. Background Technology

[0002] Slump is a method and index for measuring the workability of concrete. Currently, the main method for testing slump is to use a funnel-shaped slump bucket with an upper diameter of 10 cm, a lower diameter of 20 cm, and a height of 30 cm. Concrete is poured in three times. After each filling, a graduated rod is used to evenly tap the bucket wall from the outside to the inside 25 times. After compaction and smoothing, the bucket is then lifted. The concrete collapses due to its own weight. The slump is calculated by subtracting the height of the highest point of the concrete after collapse from the height of the bucket.

[0003] A novel concrete slump testing device, as proposed in announcement number (CN210982122U), includes a base and a slump cylinder. The base has a measuring mechanism and a lifting mechanism for lifting the slump cylinder at its top. The measuring mechanism includes a first support column, which is detachably connected to the base. A first sleeve and a second sleeve are sequentially fitted onto the first support column from bottom to top. By lifting the slump cylinder vertically, lateral twisting of the concrete during the cylinder removal process is avoided, thus improving the accuracy of the measurement results. The device is also easy to operate, highly practical, and easy to promote.

[0004] However, in the process of using the above-mentioned patent, the slump cone is first placed at the geometric center of the base, and the concrete is filled in three times. After it is filled, it is compacted and leveled. However, the concrete is vibrated manually, which makes it impossible to guarantee the force of each vibration. This can easily lead to different slump surfaces due to different vibration forces, affecting the test results. It also increases the workload of the staff and reduces the use of the testing device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a novel concrete slump testing device. This device solves the problem mentioned in the background art, where manual vibration of concrete cannot guarantee the vibration force each time, easily leading to inconsistent slump surfaces due to varying vibration forces, thus affecting the test results. It also increases the workload of workers and reduces the problems associated with using the testing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A novel concrete slump testing device includes a base plate and a threaded rod. A fixing plate is fixedly installed on the top side of the base plate. A first motor is fixedly installed on one side of the fixing plate. The output end of the first motor rotates through the fixing plate and is fixedly sleeved with a first pulley. A mounting column is fixedly installed on one side of the fixing plate. A second pulley is movably sleeved on the outer side of the mounting column. The second pulley and the first pulley are connected by the same belt. A circular plate is fixedly sleeved on the outer side of the second pulley. A fixing column is fixedly installed on one side of the circular plate. A linkage compaction component is provided on the outer side of the fixing column. A connecting block is fixedly installed on the top side of the base plate. A lifting component is provided inside the connecting block. Two long slots are respectively opened on the top side of the base plate, and a moving component and a measuring component are respectively provided in the two long slots.

[0008] In one embodiment, the linkage compaction assembly includes a linkage rod movably sleeved on the outside of the fixed column, a connecting seat provided at the other end of the linkage rod, the other end of the linkage rod being movably sleeved in the connecting seat, a connecting rod movably sleeved at the bottom of the connecting seat, and a compaction head fixedly connected to the other end of the connecting rod.

[0009] In one embodiment, a limiting plate is fixedly installed on one side of the fixing plate, the limiting plate having a circular hole, and the connecting rod being located inside the circular hole.

[0010] In one embodiment, the lifting assembly includes a threaded motor fixedly mounted on the top side of a connecting block, the output end of which rotatably passes through the connecting block and is rotatably connected to the inner wall of one side of the connecting block, and two guide rods are fixedly mounted on the inner wall of the connecting block.

[0011] In one embodiment, the same movable block is slidably mounted on the outer side of the threaded rod and the two guide rods, a connecting plate is fixedly mounted on one side of the movable block, and two hooks are fixedly mounted on the bottom side of the connecting plate.

[0012] In one embodiment, the moving component includes a second motor fixedly mounted on one side of a base plate. The output end of the second motor rotates through the base plate and is rotatably connected to the inner wall of one side of a long groove. A slider is slidably mounted on the outer side of the output end of the second motor. A placement plate is fixedly mounted on the top side of the slider, and a storage bucket is placed on the top side of the placement plate.

[0013] In one embodiment, the measuring assembly includes a fixed rod fixedly installed in another elongated groove, a movable block slidably installed on the outer side of the fixed rod, a measuring scale fixedly installed on the top side of the movable block, a sleeve movably sleeved on the outer side of the measuring scale, a marker fixedly installed on one side of the sleeve, and through holes and round holes respectively opened on both sides of the sleeve, with bolts threaded into the round holes.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This novel concrete slump testing device, by starting the first motor to drive the first pulley to rotate, thereby causing the second pulley to rotate synchronously, and then causing the circular plate on the outer side of the second pulley to drive the fixed column to rotate back and forth. When the fixed column rotates to the top, the linkage rod will pull the connecting seat and the connecting rod to move upward synchronously. When the fixed column rotates to the bottom, the connecting seat can drive the compaction head hammer at the other end of the connecting rod to hammer the concrete in the storage tank. The first motor drives the circular plate to rotate back and forth, so that the compaction head moves up and down to hammer the concrete, so that the hammering force is the same each time, avoiding different hammering forces, which will cause different slump surfaces and thus affect the test results.

[0015] By starting the threaded motor and rotating it counterclockwise, the moving block is lowered. Then, the two hooks are hung on the two rings on the outside of the storage bucket. Subsequently, the threaded motor is started and rotated clockwise, causing the moving block to move upward. When the moving block moves upward, the two hooks can lift the storage bucket vertically, avoiding lateral twisting of the concrete during the process of retrieving the storage bucket, which could lead to the collapse of the concrete.

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.

[0022] Reference Figures 1-4A novel concrete slump testing device includes a base plate 1 and a threaded rod 21. A fixing plate 2 is fixedly installed on the top side of the base plate 1. A first motor 3 is fixedly installed on one side of the fixing plate 2. The output end of the first motor 3 rotates through the fixing plate 2 and is fixedly sleeved with a first pulley 4. A mounting column 5 is fixedly installed on one side of the fixing plate 2. A second pulley 6 is movably sleeved on the outer side of the mounting column 5. A belt 7 is provided between the second pulley 6 and the first pulley 4. A circular plate 8 is fixedly sleeved on the outer side of the second pulley 6. A fixing column 9 is fixedly installed on one side of the circular plate 8. A... The linkage compaction assembly includes a connecting block 19 fixedly installed on the top side of the base plate 1, a lifting component housed within the connecting block 19, and two elongated slots on the top side of the base plate 1, each housing a moving component and a measuring component. The linkage compaction assembly includes a linkage rod 10 movably sleeved on the outside of the fixed column 9, with a connecting seat 11 at the other end of the linkage rod 10. The other end of the linkage rod 10 is movably sleeved within the connecting seat 11, and a connecting rod 12 is movably sleeved at the bottom of the connecting seat 11. A compaction head 13 is fixedly connected to the other end of the connecting rod 12. A limit plate 1 is fixedly installed on one side of the fixed plate 2. 4. The limiting plate 14 has a circular hole, and the connecting rod 12 is located in the circular hole. By putting concrete into the storage bucket 18, the second motor 15 is started to move the storage bucket 18 to below the compaction head 13. Then, the first motor 3 is started to drive the first pulley 4 to rotate. Under the action of the belt 7, the second pulley 6 rotates synchronously, which in turn causes the circular plate 8 fixedly sleeved on the outside of the second pulley 6 to drive the fixed column 9 to rotate back and forth. When the fixed column 9 rotates to the top, the linkage rod 10 will pull the connecting seat 11 to move upward synchronously. The bottom of the connecting seat 11 is movably sleeved with the connecting rod 12, so when the connecting seat 11 moves upward, it will move synchronously. When the connecting rod 12 moves upward, and the fixed column 9 moves the linkage rod 10 downward, the connecting seat 11 can drive the compaction head 13 at the other end of the connecting rod 12 to hammer the concrete in the storage tank 18. The first motor 3 drives the circular plate 8 to rotate back and forth, so that the compaction head 13 moves up and down to hammer the concrete in the storage tank 18, so that the force of each hammering is the same, avoiding different hammering forces that would cause different collapse surfaces and affect the test results. Moreover, through the set limit plate 14, the connecting rod 12 will always move within the circular hole opened in the limit plate 14 when it moves up and down, which can limit its movement trajectory.

[0023] according to Figure 1 and Figure 4As shown, the lifting assembly includes a threaded motor 20 fixedly installed on the top side of a connecting block 19. The output end of the threaded motor 20 rotatably passes through the connecting block 19 and is rotatably connected to the inner wall of one side of the connecting block 19. Two guide rods 22 are fixedly installed on the inner wall of the connecting block 19. The same moving block 23 is slidably installed on the outer side of the threaded rod 21 and the two guide rods 22. A connecting plate 24 is fixedly installed on one side of the moving block 23. Two hooks 25 are fixedly installed on the bottom side of the connecting plate 24. By starting the threaded motor 20 to rotate counterclockwise, the moving block 23 is moved down. Then, the two hooks 25 are hung on the two rings on the outside of the storage bucket 18. Subsequently, the threaded motor 20 is started to rotate clockwise, causing the moving block 23 to move up. When the moving block 23 moves up, the two hooks 25 can lift the storage bucket 18 into a vertical position, avoiding lateral twisting of the concrete during the process of taking out the storage bucket 18, which would lead to the collapse of the concrete.

[0024] according to Figure 1 and Figure 3 As shown, the moving assembly includes a second motor 15 fixedly installed on one side of the base plate 1. The output end of the second motor 15 rotates through the base plate 1 and is rotatably connected to the inner wall of one side of a long groove. A slider 16 is slidably installed on the outer side of the output end of the second motor 15. A placement plate 17 is fixedly installed on the top side of the slider 16. A storage bucket 18 is placed on the top side of the placement plate 17. By starting the second motor 15 to rotate clockwise or counterclockwise, the slider 16 can be driven to move back and forth. When the concrete needs to be compacted, starting the second motor 15 to rotate clockwise can move the storage bucket 18 to below the compaction head 13, and then the hammering compaction can begin. After compaction is completed, the second motor 15 to rotate counterclockwise can move the storage bucket 18 to below the two hooks 25, and then the storage bucket 18 can be lifted.

[0025] according to Figure 1 and Figure 3 As shown, the measuring assembly includes a fixed rod 26 fixedly installed in another long groove. A movable block 27 is slidably installed on the outside of the fixed rod 26. A measuring ruler 28 is fixedly installed on the top side of the movable block 27. A sleeve 29 is movably sleeved on the outside of the measuring ruler 28. A scale rod 30 is fixedly installed on one side of the sleeve 29. Through holes and round holes are respectively opened on both sides of the sleeve 29. A bolt is threaded in the round hole. After the storage bucket 18 is lifted, the measuring ruler 28 is pushed to move the scale rod 30 to the top of the concrete. When the bottom side of the scale rod 30 is in contact with the top side of the concrete, the other end of the bolt is pressed against the measuring ruler 28 by rotating the bolt clockwise. Then the sleeve 29 can be fixed. After the fixing is completed, because there is a through hole on one side of the sleeve 29, the scale line of the measuring ruler 28 can be seen through the through hole, so the accurate data of the collapse can be obtained.

[0026] This new concrete slump testing device is connected to a 220V mains power supply, and the main controller can be a conventional known device such as a computer for control.

[0027] In use: Concrete is placed into the storage bucket 18. The second motor 15 is started, moving the storage bucket 18 below the compaction head 13. Then, the first motor 3 is started, rotating the first pulley 4. Under the action of the belt 7, the second pulley 6 rotates synchronously, causing the circular plate 8 fixedly fitted to the outer side of the second pulley 6 to rotate the fixed column 9 back and forth. When the fixed column 9 rotates to the top, the linkage rod 10 pulls the connecting seat 11 upwards synchronously. The bottom of the connecting seat 11 is movably fitted with the connecting rod 12, so when the connecting seat 11 moves upwards, it synchronously drives the connecting rod 12 upwards. When the fixed column 9 moves the linkage rod 10 downwards, the connecting seat 11 can drive the compaction head 13 at the other end of the connecting rod 12 to hammer the concrete in the storage bucket 18. The first motor 3 drives the circular plate 8 to rotate back and forth, causing the compaction head 13 to move up and down repeatedly, hammering the concrete in the storage bucket 18 with the same force each time. To avoid uneven hammering force causing different collapse surfaces and affecting the test results, the connecting rod 12 is kept within the circular hole of the limiting plate 14 during its up-and-down movement, thus limiting its movement trajectory. After hammering and compaction, the second motor 15 is started to move the storage bucket 18 below the connecting plate 24. Then, the threaded motor 20 is started to rotate counterclockwise, causing the moving block 23 to move down. Then, the two hooks 25 are hung on the two rings on the outside of the storage bucket 18. Then, the threaded motor 20 is started to rotate clockwise, causing the moving block 23 to move up. When the moving block 23 moves up, the two hooks 25 can lift the storage bucket 18 into a vertical position, avoiding lateral twisting of the concrete during the process of removing the storage bucket 18, which could lead to the collapse of the concrete. After lifting the storage bucket 18, the measuring rod 30 is moved above the concrete, and the collapse value can be measured.
