Description

Technical Field

[0001] The present application relates to the technical field of slump measurement, and in particular to a slump monitoring device. Background Art

[0002] Slump monitoring devices are devices used to measure and assess the free fall or collapse of granular materials such as concrete and soil in an unsupported state. Such devices have important applications in civil engineering, building construction and materials science. They can provide quantitative information about the flow and consistency of materials, thereby helping engineers evaluate the suitability and handling requirements of materials.

[0003] The existing slump measurement is generally to place the slump bucket on the ground, pour concrete into the slump bucket, and fill it in multiple times. After each filling, use a tamping rod to hit the bucket wall evenly from the outside to the inside to compact the concrete, then use a trowel to smooth the surface of the concrete to make it flush with the bucket mouth, then pull the slump bucket upward to separate the slump bucket from the concrete, then use a measuring ruler to measure the height of the concrete cone, and determine the slump by comparing the height of the concrete in the bucket with the distance between the highest point of the concrete after the bucket is raised.

[0004] With regard to the above-mentioned related technologies, during the actual measurement process at the construction site, since the temporary roads at the site are usually uneven, it is difficult to ensure that the slump bucket can be placed horizontally, and there is a gap between the slump bucket and the ground. During the compaction process, concrete may also flow out of the gap. Furthermore, after the measurement is completed, the slump bucket is directly pulled up by hand. During this manual operation, it cannot be guaranteed that the slump bucket is pulled vertically upward. The inner wall of the slump bucket is likely to generate thrust to the concrete, thereby aggravating the collapse of the concrete. At the same time, it is usually difficult to ensure that the concrete can be vibrated and compacted by manually hitting the slump cylinder with a tamping rod. Combined with the above-mentioned reasons, the slump data measured is difficult to guarantee. Utility Model Content

[0005] In order to improve the accuracy of concrete slump measurement, the present application provides a slump monitoring device.

[0006] The slump monitoring device provided in this application adopts the following technical solution:

[0007] A slump monitoring device comprises a workbench, wherein the workbench has a built-in vibration module, the workbench is provided with an adjustment component for leveling the workbench, a slump measuring barrel is placed on the workbench, a lifting plate is provided on the side wall of the slump measuring barrel, the lifting plate is provided with a guide hole, and a guide rod is provided on the workbench, and the guide rod passes through the guide hole.

[0008] By adopting the above technical solution, when measuring the slump, first use the adjustment component to level the workbench, align the guide hole on the lifting plate with the guide rod, then place the slump measuring bucket on the workbench and let the guide rod pass through the lifting plate, pour concrete into the slump measuring bucket, and fill it several times. During the filling process, the vibration module keeps the start state to continuously vibrate the concrete. After the concrete is filled, use a spatula to smooth the concrete surface so that it is flush with the slump measuring bucket mouth, then pull the slump measuring bucket upward to separate the slump measuring bucket from the concrete, and then use a measuring ruler to measure the height of the concrete cone, and determine the slump by comparing the height of the concrete in the bucket with the distance between the highest point of the concrete after the bucket is raised.

[0009] Place the slump measuring bucket on a leveled workbench to ensure that the slump measuring bucket is in a horizontal position. When the slump measuring bucket is separated from the concrete, it can reduce the situation where the concrete tips over to one side and affects the slump accuracy.

[0010] At the same time, the surface of the workbench is flat, so that the workbench fits the surface of the slump measuring bucket, reducing the situation of concrete flowing out from its bottom;

[0011] Moreover, compared with manually hitting the slump bucket to compact the concrete, the vibration module has a better effect on compacting the concrete, which is conducive to improving the accuracy of the measurement data;

[0012] And in the process of pulling the slump measuring bucket upward, the guide rod plays a guiding role, which can keep the slump measuring bucket in a vertical state while rising, reducing the impact on the measurement caused by the inner wall of the slump measuring bucket pushing down concrete, thereby improving the accuracy of concrete slump measurement as a whole.

[0013] Optionally, the adjustment assembly includes an adjusting screw, and a plurality of the adjusting screws are provided. The adjusting screw passes through the workbench and is threadedly connected to the workbench. An adjusting nut is fixed to one end of the adjusting screw, and the adjusting nut is rotatably connected to a support seat. The support seat is located under the workbench, and a level bubble is provided on the workbench.

[0014] By adopting the above technical solution, the support base is placed on the ground, and then the adjusting nut is rotated, and the adjusting nut drives the adjusting screw to rotate, so as to fine-tune the workbench. During the process of adjusting the workbench, the level bubble is observed to determine whether the workbench is leveled.

[0015] Optionally, two lifting plates are provided, and two guide rods are provided, and the two lifting plates are stacked about the central axis of the slump measuring cylinder, and the two lifting plates can be simultaneously mounted on one guide rod each.

[0016] By adopting the above technical solution, the two guide rods guide the lifting plate at the same time, so that the slump measuring bucket can be lifted upward more smoothly.

[0017] Optionally, the workbench is provided with a fixing component for fixing the slump measuring bucket on the workbench.

[0018] By adopting the above technical solution, since the vibration module will vibrate the slump measuring barrel, the slump measuring barrel may be displaced upward along the guide rod, which may easily cause a gap between the slump measuring barrel and the workbench, resulting in the outflow of concrete slurry, thereby affecting the accuracy of concrete slump measurement. The fixing component fixes the slump measuring barrel, limits the upward displacement of the slump measuring barrel, reduces the leakage of concrete slurry, and further improves the accuracy of concrete slump measurement.

[0019] Optionally, the fixing assembly includes a first clamping plate and a second clamping plate, the first clamping plate and the second clamping plate are arranged opposite to each other, the first clamping plate and the second clamping plate are both slidably connected to the workbench, the workbench is rotatably connected with a cam, the cam is provided with two protrusions, and the two protrusions are symmetrically arranged about the central axis of the cam, both sides of the first clamping plate are connected with connecting rods, the connecting rod passes through the second clamping plate, the connecting rod is parallel to the side surface of the first clamping plate and the side surface of the second clamping plate, the ends of the two connecting rods away from the first clamping plate are commonly connected to an adjusting plate, the cam is located between the adjusting plate and the second clamping plate, the connecting rod sleeve is provided with a spring, one end of the spring is fixed to the first clamping plate, and the other end of the spring is fixed to the second clamping plate.

[0020] By adopting the above technical scheme, when the slump measuring barrel is fixed, the cam is rotated, one protrusion of the cam abuts against the second clamping plate, and the other protrusion abuts against the adjusting plate. With the rotation of the cam, the second clamping plate and the adjusting plate move away from each other, the adjusting plate drives the connecting rod to move, and the connecting rod drives the first clamping plate to move, and the first clamping plate and the second clamping plate approach each other. When the side of one protrusion farthest from the center of the cam is tangent to the second clamping plate, and the side of the other protrusion farthest from the center of the cam is tangent to the adjusting plate, the first clamping plate and the second clamping plate clamp the slump measuring barrel, the spring is in a compressed state, and at this time, the line connecting the points on the top surfaces of the two protrusions farthest from the center of the cam is perpendicular to the second clamping plate and the adjusting plate, thereby ensuring that the cam will not rotate by itself in the absence of an external force cam.

[0021] When it is necessary to release the fixation of the slump measuring barrel, the cam is manually rotated, the spring returns to its natural state and drives the second clamping plate and the first clamping plate to move away from each other, the first clamping plate drives the connecting rod to move, and the connecting rod drives the adjusting plate to move closer to the second clamping plate, thereby releasing the fixation of the slump measuring barrel.

[0022] Optionally, the workbench is rotatably connected to a rotating shaft, the cam is coaxially fixed on the rotating shaft, and the rotating shaft is connected to a shifting rod.

[0023] By adopting the above technical solution, the user rotates the lever to drive the rotating shaft to rotate, thereby conveniently driving the cam to rotate.

[0024] Optionally, a measuring rod is installed on the workbench, a scale is set on the measuring rod, a sliding sleeve is sleeved on the measuring rod, a measuring ruler is connected to the sliding sleeve, and a tightening bolt is threadedly connected to the sliding sleeve.

[0025] By adopting the above technical solution, when measuring the height of concrete after collapse, loosen the locking bolt, grab the sliding sleeve and move it up and down along the measuring rod. When the bottom of the measuring ruler contacts the top of the concrete, tighten the locking bolt to limit the movement of the sliding sleeve. At this time, read the scale of the measuring rod aligned with the bottom of the sliding sleeve to calculate the height of the concrete after collapse, and then compare it with the height of the slump measuring bucket to obtain the slump value.

[0026] Optionally, a battery module for providing power to the vibration module is disposed in the workbench, a switch for controlling the start of the vibration module is disposed on the workbench, and a charging port for charging the battery module is disposed on the workbench.

[0027] By adopting the above technical solution, when slump measurement is carried out on site, the vibration module can be started by directly turning on the switch, without the need to reconnect the power temporarily on site, which is convenient and quick.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. Place the slump measuring bucket on a leveled workbench to ensure that the slump measuring bucket is in a horizontal position. When the slump measuring bucket is separated from the concrete, the concrete is prevented from tipping over to one side and affecting the slump accuracy.

[0031] 3. Compared with manually hitting the slump bucket to compact the concrete, the vibration module has a better effect on compacting the concrete, which is conducive to improving the accuracy of the measurement data;

[0032] 4.

[0037] The following is combined with Figure 1-2 This application is described in further detail.

[0038] The embodiment of the present application discloses a slump monitoring device.

[0039] like Figure 1 and Figure 2The slump monitoring device includes a workbench 1, which has a built-in vibration module 11. The top surface of the vibration module 11 is flush with the top surface of the workbench 1. A battery module 12 for providing power to the vibration module 11 is installed in the workbench 1. The battery module 12 is electrically connected to the vibration module 11. A switch 13 for controlling the start of the vibration module 11 is installed on one side of the workbench 1. A charging port 14 for charging the battery module 12 is provided on one side of the workbench 1. An adjusting component 2 for leveling the workbench 1 is provided at the bottom of the workbench 1, a slump measuring barrel 3 is placed on the workbench 1, two guide rods 15 are installed on the top of the workbench 1, and two lifting plates 31 are provided along the circumference of the slump measuring barrel 3, and the two lifting plates 31 are symmetrically arranged about the central axis of the slump measuring barrel 3. Guide holes 32 are opened on the lifting plates 31, and the two guide rods 15 pass through the guide holes 32 of one lifting plate 31 respectively. A fixing component 4 for fixing the slump measuring barrel 3 is provided on the workbench 1, a measuring rod 5 is fixed on the top surface of the workbench 1, the measuring rod 5 is perpendicular to the workbench 1, a scale 51 is provided on the measuring rod 5, and the measuring rod 5 is provided with a sliding sleeve 52, the sliding sleeve 52 is threadedly connected with a tightening bolt 53, and the sliding sleeve 52 is connected with a measuring ruler 54.

[0040] When measuring the slump, first use the adjustment component 2 to level the workbench 1, align the guide hole 32 on the lifting plate 31 with the guide rod 15, then place the slump measuring barrel 3 on the workbench 1 and let the guide rod 15 pass through the lifting plate 31, then fix the slump measuring barrel 3 with the fixing component 4, pour concrete into the slump measuring barrel 3, and fill it in multiple times. During the filling process, the vibration module 11 remains in the started state to continuously vibrate the concrete. After the concrete is filled, turn off the vibration module 11, release the fixing component 4, and use a spatula to smooth the surface of the concrete so that it is aligned with the slump measuring barrel. The 3 openings are aligned, and then the lifting plate 31 is lifted upwards. The lifting plate 31 moves along the guide rod 15, so that the slump measuring barrel 3 moves vertically upwards, and the slump measuring barrel 3 is separated from the concrete. Then the tightening bolt 53 is loosened, and the sliding sleeve 52 is grasped and moved up and down along the measuring rod 5. When the bottom of the measuring ruler 54 contacts the top of the concrete, the tightening bolt 53 is tightened to limit the movement of the sliding sleeve 52. At this time, read the scale 51 of the measuring rod 5 aligned with the bottom of the sliding sleeve 52, and the height of the concrete after collapse can be calculated, and then compared with the height of the slump measuring barrel 3 to obtain the slump value.

[0041] The slump measuring bucket 3 is placed on the leveled workbench 1 to ensure that the slump measuring bucket 3 is in a horizontal position. When the slump measuring bucket 3 is separated from the concrete, the concrete is prevented from tipping over to one side and affecting the slump accuracy.

[0042] At the same time, the surface of the workbench 1 is flat, so that the workbench 1 fits the surface of the slump measuring barrel 3, and the fixing component 4 fixes the slump measuring barrel 3, restricting the slump measuring barrel 3 from being vibrated and moving upward, reducing the leakage of concrete slurry, and further improving the accuracy of concrete slump measurement;

[0043] Compared with manually hitting the slump bucket to compact the concrete, the vibration module 11 has a better effect of compacting the concrete, which is conducive to improving the accuracy of the measurement data;

[0044] In the process of pulling the slump measuring barrel 3 upward, the guide rod 15 plays a guiding role, which can keep the slump measuring barrel 3 in a vertical state as it rises, reducing the possibility that the inner wall of the slump measuring barrel 3 pushes down concrete and affects the measurement. By controlling in many aspects, the accuracy of concrete slump measurement is improved as a whole.

[0045] like Figure 1 The adjustment assembly 2 includes four adjusting screws 21, each of which is located at a corner of the workbench 1. The adjusting screws 21 pass through the workbench 1 and are threadedly connected to the workbench 1. An adjusting nut 22 is fixed to one end of the adjusting screw 21 located below the workbench 1. The adjusting nut 22 is rotatably connected to a support seat 23. A level bubble 24 is installed on the top surface of the workbench 1.

[0046] The support base 23 is placed on the ground, and then the adjusting nut 22 is rotated, and the adjusting nut 22 drives the adjusting screw 21 to rotate, so as to fine-tune the workbench 1. During the adjustment of the workbench 1, the level bubble 24 is observed to determine whether the workbench 1 is leveled.

[0047] like Figure 1 The fixing assembly 4 includes a first clamping plate 41 and a second clamping plate 42, both of which are slidably connected to the top surface of the workbench 1. An arc groove is provided on the first clamping plate 41 and the second clamping plate opposite to each other, and the side wall of the slump measuring barrel 3 fits the arc groove. Connecting rods 43 are fixed on both sides of the first clamping plate 41, and the connecting rods 43 pass through the second clamping plate 42. An adjusting plate 44 is bolted to one end of the two connecting rods 43 away from the first clamping plate 41. The connecting rods 43 are parallel to the sides of the first clamping plate 41 and the second clamping plate 42. A spring 45 is sleeved on the connecting rod 43, and one end of the spring 45 is fixed to the first clamping plate 41, and the other end of the spring 45 is fixed to the second clamping plate 42.

[0048] A rotating shaft 46 is rotatably connected to the workbench 1, and a lever 47 and a cam 48 are fixed to the rotating shaft 46. Two protrusions 49 are fixed to the side of the cam 48. The outer peripheral surfaces of the two protrusions 49 are arc-shaped surfaces, and the two protrusions 49 are symmetrically arranged about the center of the cam 48.

[0049] When fixing the slump measuring barrel 3, the user rotates the lever 47 to drive the rotating shaft 46 to rotate, thereby driving the cam 48 to rotate, a protrusion 49 of the cam 48 abuts against the second clamping plate 42, and another protrusion 49 abuts against the adjusting plate 44. As the cam 48 rotates, the second clamping plate 42 and the adjusting plate 44 move away from each other, the adjusting plate 44 drives the connecting rod 43 to move, and the connecting rod 43 drives the first clamping plate 41 to move, and the first clamping plate 41 and the second clamping plate 42 approach each other. When the side of the protrusion 49 farthest from the center of the cam 48 is tangent to the second clamping plate 42, and the side of the other protrusion 49 farthest from the center of the cam 48 is tangent to the adjusting plate 44, the first clamping plate 41 and the second clamping plate 42 clamp the slump measuring barrel 3, the spring 45 is in a compressed state, and at this time, the line connecting the points of the top surfaces of the two protrusions 49 farthest from the center of the cam 48 is perpendicular to the second clamping plate 42 and the adjusting plate 44, thereby ensuring that the cam 48 will not rotate by itself without an external force on the cam 48;

[0050] When it is necessary to release the fixation of the slump measuring barrel 3, the cam 48 is manually rotated, the spring 45 returns to its natural state and drives the second clamping plate 42 and the first clamping plate 41 to move away from each other, the first clamping plate 41 drives the connecting rod 43 to move, and the connecting rod 43 drives the adjusting plate 44 to move close to the second clamping plate 42, thereby releasing the fixation of the slump measuring barrel 3.

[0051] The implementation principle of the embodiment of the present application is: the slump measuring bucket 3 is placed on the leveled workbench 1 to ensure that the slump measuring bucket 3 is in a horizontal position. When the slump measuring bucket 3 is separated from the concrete, the situation in which the concrete tilts to one side and affects the slump accuracy is reduced;

[0052] At the same time, the surface of the workbench 1 is flat, so that the workbench 1 fits the surface of the slump measuring bucket 3, reducing the situation where concrete flows out from the bottom thereof;

[0053] Moreover, compared with manually hitting the slump bucket to compact the concrete, the vibration module 11 has a better effect of compacting the concrete, which is conducive to improving the accuracy of the measurement data;

[0054] And in the process of pulling the slump measuring barrel 3 upward, the guide rod 15 plays a guiding role, which can enable the slump measuring barrel 3 to maintain a vertical state while rising, reducing the possibility of the inner wall of the slump measuring barrel 3 pushing down concrete and affecting the measurement, thereby improving the accuracy of concrete slump measurement as a whole.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
