Description

Technical Field

[0001] This invention relates to the field of ready-mixed concrete testing equipment technology, and in particular to an automated measuring device for the slump and spread of concrete between mixing layers in a mixing tower. Background Technology

[0002] For concrete, slump and spread are core indicators for evaluating its workability, jointly characterizing its consistency and fluidity. Specifically, in a slump test, freshly mixed concrete is layered into a cone-shaped slump cone of a specific size according to a prescribed method. After filling and leveling, the cone is slowly lifted vertically upwards. The concrete then collapses under its own weight. The vertical height difference between the highest point of the collapsed concrete and the original height of the top of the slump cone is measured; this difference is the slump value. After the slump test (after lifting the slump cone), the concrete collapses and spreads out on the ground (or slab) in a cake-like shape. The maximum diameter of this concrete cake in two vertical directions is measured, and the average value is the spread value.

[0003] Currently, concrete batching plants primarily rely on manual testing for slump and spread tests on freshly produced ready-mixed concrete. Test operators manually push a trolley to the mixer truck's discharge port to collect samples, which are then manually transported to the laboratory for slump and spread testing. Existing testing methods are inefficient, lack automation, and are prone to inconsistencies due to the difficulty of directly removing the slump cone vertically during manual testing, resulting in significant human influence on the measurement results. Summary of the Invention

[0004] In view of this, the present invention provides an automated measuring device for the slump and spread of concrete between mixing layers in a mixing plant, in order to solve the problems of low efficiency and easy error in the prior art of manual material handling and testing.

[0005] An automated measuring device for the slump and spread of concrete between mixing layers in a mixing tower includes a base positioned below the discharge port of the mixing tower. A slump bucket, truncated cone shape, is movably mounted on the base to receive concrete from the discharge port. The slump bucket has openings at both the top and bottom. A base plate is also included to receive the concrete within the slump bucket. The device further includes a motion mechanism connecting the slump bucket and moving it above the discharge port and the base plate. A pad located below the slump bucket and used to seal the bottom opening of the slump bucket is mounted on the motion mechanism. A height measuring mechanism is mounted on one side of the base plate to measure the height of the concrete on the base plate. Multiple concentric spread measuring scale rings are arranged on the upper surface of the base plate. A detection probe is mounted above the frame to display the distribution of concrete on the spread measuring scale rings.

[0006] Furthermore, the height measuring mechanism includes a measuring ruler located on one side of the base plate and a detection probe located on the other side of the base plate.

[0007] Furthermore, the detection probe is vertically guided and moved on the frame of the equipment, and the movement stroke of the detection probe coincides with the measuring range of the measuring ruler.

[0008] Furthermore, the detection probe is movably mounted on the frame, and the movement trajectory of the detection probe is located within the same horizontal plane.

[0009] Furthermore, the frame is used to be installed on the side of the discharge port of the lower layer of the mixing plant. The equipment also includes a control box for calculating the slump and spread of the measured concrete and feeding back the slump and spread information to the mixing plant's production control system to improve the concrete performance.

[0010] Furthermore, the motion mechanism includes a lifting column, the slump bucket and the pad are connected to the lifting column, a first telescopic mechanism is provided between the slump bucket and the lifting column, and a second telescopic mechanism is provided between the pad and the lifting column.

[0011] Furthermore, a rotating mechanism is also provided between the lifting column and the first telescopic mechanism.

[0012] Furthermore, the lifting column is rotatably mounted on the base.

[0013] Furthermore, a slab is provided on the lifting column above the first telescopic mechanism, and a third telescopic mechanism is provided between the slab and the lifting column so that when the slab moves with the third telescopic mechanism, it passes through the top opening of the slump bucket and scrapes off excess concrete.

[0014] Furthermore, the device includes a frame, on which the base plate is rotatably mounted, and the rotation axis of the frame is parallel to the surface of the base plate.

[0015] Furthermore, the equipment includes a frame on which water nozzles for spraying water outward are installed. Multiple water nozzles are provided for cleaning the slump bucket and the bottom plate respectively.

[0016] Furthermore, the frame is provided with a horizontally movable pushing structure, which is located above the base plate and adheres to the upper surface of the base plate so that it can scrape away the concrete on the base plate when the pushing structure moves horizontally.

[0017] The beneficial effects of the automated measurement device for slump and spread of concrete between mixing plant layers in this invention are as follows: The slump bucket is used to collect concrete from the discharge outlet of the mixing plant layer, facilitating testing. Both ends of the slump bucket have openings for easy receiving and pouring. The pouring direction can be selected according to the type of concrete material to conduct upright or inverted slump tests. A pad is also provided to store a certain amount of concrete. For convenient automatic material handling, both the slump bucket and the pad are mounted on a moving mechanism. This mechanism allows the slump bucket and pad to move synchronously, preventing leakage during movement. Simultaneously, the movement allows the slump bucket to move between the discharge outlet and the bottom plate, facilitating the pouring of concrete from the slump bucket onto the bottom plate. Due to the pad and… The slump cone can move independently, so after the slump cone is placed on the base plate, the pad can be removed. If the slump cone moves upward at this time, a slump test can be performed. Moreover, because it is controlled by the motion mechanism, the speed and direction of the slump cone's detachment can be controlled more precisely. At the same time, a height measuring mechanism is set on one side of the base plate to measure the height of the concrete, making it easy to know the height difference before and after pouring, and thus to determine its slump. In addition, a concentric scale ring for measuring the spread of the concrete is set on the base plate, making it easy to see the spread of the concrete on the base plate after pouring. To achieve automated detection, a detection probe is set on the top of the frame, allowing direct observation of the concrete spread, which is more accurate. This solves the problems of low efficiency and easy error in the existing technology of manual material handling and testing. Attached Figure Description

[0030] To better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings.

[0031] In Embodiment 1 of the automated measuring device for the slump and spread of concrete between mixing tower layers (hereinafter referred to as the measuring device) of this invention:

[0032] The measuring device in this embodiment is equipped with a motion mechanism and a slump bucket and a pad connected to the motion mechanism, which facilitates the automatic collection of concrete to be tested and the automatic transport of concrete to the test area through the motion mechanism; in addition, the height measuring mechanism can also automatically measure the height before and after the test, which facilitates the automatic generation of results.

[0033] Specifically, such as Figure 1 and Figure 2As shown, the measuring device 6 includes a frame 1, a material-collecting mechanism 2 mounted on the frame 1, and an intelligent measuring mechanism 3 mounted on the frame 1. The frame 1 includes a transverse support 11, a longitudinal support 12, and a base 13 at the bottom. The base 13 can bear the weight of the entire measuring device. Since the measuring device 6 needs to collect material from the discharge port of the mixing tower's material layer, and the mixing tower typically generates significant noise and vibration during operation, a shock absorber is also installed at the bottom of the base 13. This shock absorber connects the device to the side of the discharge port 7 of the mixing tower's material layer, thereby reducing the vibration of the entire device and preventing measurement errors due to vibration during the test. Figure 4 As shown, in this embodiment, the frame is used to be installed on the side of the material outlet 7 of the lower material layer of the mixing tower for easy material collection. Of course, in other embodiments, the device can also be installed in other locations or used alone for concrete testing.

[0034] The material handling mechanism 2 is mounted on the base 13. Specifically, the material handling mechanism 2 includes a first longitudinal guide rail 24 and a longitudinal rotating shaft 22. A first motor 21 is connected to the end of the longitudinal rotating shaft 22. The rotation of the first motor 21 can drive the rotation of the longitudinal rotating shaft 22 and the first longitudinal guide rail 24. A lifting column 25 is also mounted on the first longitudinal guide rail 24. The lifting column 25 is movable up and down on the first longitudinal guide rail 24. Specifically, a second motor 23 is mounted on the side of the lifting column 25. The second motor 23 drives the lifting column 25 to move up and down. A slump bucket 211 and a pad 212 located at the bottom of the slump bucket 211 are mounted on the lifting column 25. The slump bucket 211 is frustum-shaped, and both the upper and lower ends of the slump bucket 211 have openings of different sizes. The size of the pad 212 is not smaller than the size of the larger opening on the slump bucket 211.

[0035] A first telescopic mechanism is provided between the slump bucket 211 and the lifting column, and a second telescopic mechanism is provided between the pad plate 212 and the lifting column. Specifically, the first telescopic mechanism is a first telescopic rotary cylinder 27, and the second telescopic mechanism is a second telescopic cylinder 28. One end of the first telescopic rotary cylinder 27 is fixedly mounted on the lifting column, and the other end is connected to the center of the slump bucket 211. Before and after the first telescopic rotary cylinder 27 rotates, the height of the upper and lower ends of the slump bucket 211 remains unchanged, avoiding interference with the pad plate 212 and also avoiding gaps between them. The second telescopic cylinder 28 facilitates the pad plate 212 to seal or open the bottom opening of the slump bucket 211, thereby enabling the transfer of concrete.

[0036] During the material receiving process, it is necessary to ensure that the concrete is compacted within the slump bucket 211. The discharge speed at the outlet is relatively fast, and when receiving material, especially when the smaller opening is at the top, there is a possibility that the concrete may not be fully compacted. Therefore, a fourth telescopic cylinder 29 and a small pneumatic vibrator 213 are installed on the lifting column to facilitate vibration and tapping of the pad 212, thereby ensuring that the concrete is compacted within the slump bucket 211. Furthermore, a third telescopic cylinder 26 is installed on the lifting column, with a screed 210 at the end of its telescopic rod. The telescopic movement of the third cylinder drives the screed 210 to scrape the concrete at the upper opening of the slump bucket 211, facilitating leveling for further testing. In other words, the lifting column is connected from top to bottom to the screed 210, slump bucket 211, pad 212, and small pneumatic vibrator 213, facilitating material receiving from the discharge outlet of the mixing plant.

[0037] A base plate 34 is also provided on the frame 1 to receive concrete poured from the slump bucket 211. The base plate 34 is rotatably mounted on the frame 1. Specifically, a transverse rotating shaft 35 is provided on the frame 1, passing through the base plate 34, and the axis of the transverse rotating shaft 35 is parallel to the surface of the base plate 34. A third motor 31 is provided at one end of the transverse rotating shaft 35. The third motor 31 drives the transverse rotating shaft 35 to rotate, thereby driving the base plate 34 to rotate. This allows the concrete on the base plate 34 to be poured out by tilting after use, and also keeps the base plate 34 in a horizontal position during testing, facilitating the receipt of concrete. It is worth noting that in this embodiment, the base plate 34 has a double-layer plate structure, with a weighing sensor 312 installed between the two layers. The transverse rotating shaft 35 is fixedly mounted on the bottom of the base plate 34, facilitating the measurement of the weight of the concrete after it is poured. Since the volume of the slump bucket 211 is fixed, the density of the concrete can also be calculated, providing data support for concrete production.

[0038] To conduct the slump test, the height of the concrete on the base plate 34 also needs to be measured. Therefore, a height measuring mechanism is also provided on the frame 1. In this embodiment, the height measuring mechanism includes a measuring ruler 311 vertically arranged on one side of the base plate 34 and a second detection probe 310 located on the other side of the base plate 34. The second detection probe 310 is vertically guided on the frame 1. Specifically, a first longitudinal transport rail 39 is provided on the frame 1, and the second detection probe 310 is mounted on the first longitudinal transport rail 39. To facilitate the vertical movement of the second detection probe 310, a fifth motor 33 is also provided on the first longitudinal transport rail 39. Specifically, in this embodiment, the second detection probe 310 is a laser emitter, and a receiver is provided on the measuring ruler 311. The second detection probe 310 can move from bottom to top. When the receiver receives a signal for the first time, the height at that moment is the height of the concrete.

[0039] In addition, such as Figure 3 As shown, to detect the slump, a slump measuring scale ring 38 is provided on the base plate 34. Multiple slump measuring scale rings 38 with different diameters are concentrically arranged to form a ring. Before pouring the concrete from the slump bucket 211, the position needs to be aligned with the center of the slump measuring scale ring 38. Then, the degree of slump can be easily determined by observing the degree of slump on the base plate 34. For automated detection, a first detection probe 37 is also provided on the top of the frame 1. The first detection probe 37 is slidably mounted on the frame 1. Specifically, a first transverse transport guide rail 36 is provided on the top of the frame 1, and the first detection probe 37 is mounted on the first transverse transport guide rail 36. To drive the movement of the first detection probe 37, a fourth motor 32 is also provided on the first transverse transport guide rail 36. In this embodiment, the first detection probe 37 is an industrial camera, which determines the slump of the concrete by taking pictures. Of course, in other embodiments, if the first detection probe 37 is directly installed above the center of the extension measurement scale ring 38, the first transverse transport guide rail 36 and the fourth motor 32 may not be required.

[0040] The quality of concrete may vary at different production cycles. To enable multiple tests on the concrete, the equipment needs to be cleaned after each test. In this embodiment, an automatic cleaning device 4 is also provided. Specifically, the automatic cleaning device 4 includes a water storage tank 43 and a water pump 44 for pumping water out of the water storage tank 43. A water delivery pipe 45 is connected to the water pump 44, and a water outlet nozzle is provided at the end of the water delivery pipe 45. Specifically, there are three sets of water outlet nozzles, including a first water outlet nozzle 48 located above the slump bucket 211, a second water outlet nozzle 49 arranged parallel to the base plate 34, and a third water outlet nozzle 410 arranged parallel to the base 13. The arrangement of the three sets of water outlet nozzles facilitates cleaning of different locations. To facilitate cleaning, a second transverse transport guide rail 47 and a sixth motor 46 are installed on the frame 1 to drive the first water nozzle 48 to move horizontally. A fifth telescopic cylinder 41 is installed on the frame 1 to drive the movement of the second water nozzle 49. Since this cylinder is parallel to the base plate 34, a first scraper 411 is connected to the end of the fifth telescopic cylinder 41. The movement of the first scraper 411 facilitates the removal of residual concrete on the base plate 34. In addition, a sixth telescopic cylinder 42 is installed on the base 13. The movement of the sixth telescopic cylinder 42 drives the movement of the third water nozzle 410. Furthermore, to scrape away any concrete that may be present on the base 13, a second scraper 412 is installed at the end of the sixth telescopic cylinder 42.

[0041] In addition, a control box 5 is installed on the frame 1 to control the aforementioned equipment. The control box 5 contains a pre-programmed control program for easy control of the movement of various parts. It can also receive data from the weighing sensor 312, the first detection probe 37, and the second detection probe 310 to calculate the concrete's density, slump, and spread. Because the equipment is located on the side of the discharge port of the mixing plant's lower layer, the time required from sampling to testing is short, and the concrete has not undergone prolonged static setting and solidification. Therefore, the measured concrete density, slump, and spread are closer to the actual values ​​with less error. Furthermore, the control box 5 can also feed the above data back to the mixing plant's production control system, allowing for fine-tuning of the concrete mix ratio or mixing parameters within the mixing plant to ensure the concrete quality meets requirements. In other words, the control box 5 serves as feedback on concrete quality to the mixing plant's production control system, enabling real-time quality control and adjustments.

[0042] The following is a brief description of its working process. During the operation of the mixing plant, concrete is discharged from the outlet of the lower material layer. Once the discharge is uniform and stable, sampling and testing can begin. Specifically, the operators in the production control workshop can choose to conduct either an upright or inverted slump test (i.e., the orientation of the slump bucket opening) based on the type of concrete material at the lower material layer outlet. They rotate the lifting column and control the first telescopic cylinder to extend it to a suitable length, thus transporting the slump bucket 211 to the lower material layer outlet for receiving. During the receiving process, the pad 212 must be kept at the lower end of the slump bucket 211 to facilitate sealing the opening at the lower end of the slump bucket 211. Once the discharge from the outlet is continuous and stable, the concrete discharged from the outlet is received. During this receiving process, the fourth telescopic cylinder 29 is kept extended, so that the small pneumatic vibrator 213 is located below the pad 212, and the vibration flattens the concrete in the slump bucket 211, expelling air bubbles. To ensure that the concrete just fills the slump bucket 211, the third telescopic cylinder 26 should be controlled to complete one telescopic movement so that the scraper can level the opening at the top of the slump bucket 211. Of course, the initial shape of the slump bucket 211 is required to be different under different testing conditions. In this embodiment, the slump bucket 211 is arranged with the larger opening facing upwards. In other embodiments, the larger opening of the slump bucket 211 can also be arranged with the larger opening facing downwards. According to different requirements, the first telescopic rotary cylinder needs to be controlled to adjust the slump bucket 211 into place before receiving the material.

[0043] After material collection is completed, the lifting column rotates along the longitudinal pivot 22, causing the slump bucket 211 to move from the discharge port to the base plate 34. Through the rotation of the lifting column and the extension of the first telescopic rotary cylinder and the second telescopic cylinder 28, the slump bucket 211 and the pad 212 are placed above the base plate 34. Then, the lifting column is lowered, causing the pad 212 to adhere to the base plate 34. Next, the second telescopic cylinder 28 is retracted, exposing the opening at the bottom of the slump bucket 211. Then, the lifting column is raised, lifting the slump bucket 211. During this upward movement, the concrete inside the slump bucket 211 is spread evenly on the base plate 34. Because a lifting column is used for control, the direction in which the slump bucket 211 is lifted is always vertical.

[0044] After the experiment is completed, the data needs to be measured. In this embodiment, an intelligent measuring mechanism 3 is set up to detect the concrete. The height of the concrete on the base plate 34 is detected by a measuring ruler 311 set on one side of the base plate 34 for height detection. This allows for the measurement of the height difference before and after the concrete collapses, thus facilitating the determination of the slump of this batch of concrete. Specifically, a second detection probe 310 is set on the other end of the measuring ruler 311 on the base plate 34. The height of the concrete is measured by the second detection probe 310 and the measuring ruler 311, and then compared with the original height of the space inside the slump bucket 211 to obtain the slump.

[0045] In concrete performance testing, slump is equally important. The slump of a batch of concrete can be measured by setting a slump measuring scale ring 38 on the base plate 34. Specifically, the boundary of the concrete is measured by the slump measuring scale ring 38 on the base plate 34. The first detection probe 37 at the top of the frame 1 is used to photograph the concrete. The first detection probe 37 is moved directly above the center of the slump measuring scale ring on the base plate 34, and its slump is determined based on the slump measuring scale ring 38 reached by the concrete. Of course, since a weighing sensor 312 is also installed inside the base plate 34, it can detect the weight of the concrete on the base plate 34. The volume of the concrete is equal to the volume of the slump test bucket 211, so the density of the concrete can also be determined.

[0046] During the same batch of tests, sometimes more than one test may be conducted, with additional tests performed at intervals. Before each test, the base plate 34 must be kept clean and free of excess concrete. This means that any concrete from the previous test must be removed. After the test, an automatic cleaning device 4 is used to clean any remaining concrete from the base plate 34 and the slump bucket 211. Specifically, the third motor 31 drives the transverse rotating shaft 35, causing the base plate 34 to rotate around the axis of the transverse rotating shaft 35, allowing the concrete to pour down before returning to a horizontal position. The slump bucket 211 and the pad 212 are then moved above the base plate 34. Three water nozzles are activated to clean the slump bucket 211 and the base plate 34. During the cleaning process, because there may be a significant amount of concrete residue on the base plate 34, the first scraper 411 and the second scraper 412 are used to clean the concrete on the base plate 34 and the base 13, respectively. This ensures that the concrete on the base plate 34 has been thoroughly cleaned before the next test, preventing any impact on the subsequent test.

[0047] Furthermore, the control box 5 installed on the frame 1 can obtain data detected by the first detection probe 37 and the second detection probe 310, as well as the density information of the concrete. This information is then promptly fed back to the mixing plant's production control system or controller, facilitating adjustments to raw materials or processes to alter the concrete's properties. Of course, if other information collection units exist within the mixing plant, feedback can also be sent to these components for control purposes.

[0048] It should be understood that the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
