Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of slump measurement, and specifically relates to a device for easily measuring slump. Background Technique
[0002] Slump refers to the workability of concrete. Specifically, it ensures the normal progress of construction, including the water retention, fluidity, and cohesiveness of concrete. It is measured by a quantitative index to determine the level of its degree and whether the construction can proceed normally. It refers to the plasticizing performance and pumpability of concrete. The main factors affecting the slump of concrete include changes in gradation, water content, weighing deviation of weighing scales, dosage of admixtures, and the often overlooked temperature of cement.
[0003] In the concrete slump test, after the slump bucket is filled with the mixture, when measuring the slump, it is often necessary to first determine the height of the bucket and then align the caliper with the highest point of the mixture to measure the slump. However, there are some limitations in this traditional slump test. When the caliper is translated to the highest point of the mixture, it is inevitable that errors will be caused by human factors, resulting in a deviation between the measured slump and the actual value; different experimenters' observations of the slump are also different, which will also cause the experimental data to deviate from the actual situation, etc. Summary of the Utility Model
[0004] The purpose of this utility model is to provide a device for easily measuring slump, which can overcome the limitations of the prior art and provide a more efficient and stable measurement of slump
[0005] The technical solution adopted by this utility model is specifically as follows:
[0006] A device for easily measuring slump includes a slump bucket and a slump bottom plate. The slump bucket is arranged above the slump bottom plate, and a rectangular bar is fixedly connected above the slump bucket. The other end of the rectangular bar is fixedly connected with a ring, and the ring is fixedly connected with a lifting column;
[0007] A cylindrical slide rail is fixedly connected above the slump bottom plate. A cylindrical bearing is slidably arranged on the outer side of the cylindrical slide rail. A fixed cylinder is fixedly arranged outside the cylindrical bearing. A laser pen is arranged inside the fixed cylinder, and a control switch is arranged on the laser pen;
[0008] Among them, place the concrete in the slump bucket. By adjusting the lifting column, it drives the slump bucket to rise and fall through the ring and separates it from the slump bottom plate and the concrete. Start the laser pen through the control switch, and then adjust the cylindrical bearing to drive the fixed cylinder to move on the cylindrical slide rail, so that the laser pen measures the height of the concrete, and then measures the moving distance of the laser pen on the cylindrical slide rail to ensure that the slump can be accurately calculated.
[0009] Further, the number of the rectangular bars is multiple, and the multiple rectangular bars are arranged in an array along the center of the slump bucket.
[0010] Further, the number of the lifting columns is multiple, and the multiple lifting columns are respectively arranged on four sides of the slump bottom plate.
[0011] Further, a plurality of bottom plate struts are fixedly arranged at the bottom of the slump bottom plate, and the plurality of bottom plate struts are arranged in an array along the center of the slump bottom plate.
[0012] Further, the height of the cylindrical slide rail is the same as that of the slump bucket.
[0013] Further, a fixing hole is formed above the fixing cylinder, and a fixing screw is threadedly connected in the fixing hole.
[0014] The technical effects achieved by the present utility model are as follows:
[0015] An apparatus for easily measuring the slump of the present utility model can effectively measure the slump through the lifting columns, effectively reduce the errors caused by human factors, and improve the accuracy of slump measurement.

[0022] In order to make the purpose and advantages of the present utility model clearer, the following specifically describes the present utility model in combination with embodiments. It should be understood that the following text only describes one or several specific implementation modes of the present utility model, and does not strictly limit the protection scope of the specific requests of the present utility model.
[0023] As Figures 1 - 3 shown, a device for easily measuring the slump includes a slump bucket 10 and a slump bottom plate 20. The slump bucket 10 is arranged above the slump bottom plate 20, and a rectangular bar 11 is fixedly connected above the slump bucket 10. The other end of the rectangular bar 11 is fixedly connected with a ring 12, and the ring 12 is fixedly connected with a lifting column 13;
[0024] A cylindrical slide rail 21 is fixedly connected above the slump bottom plate 20. A cylindrical bearing 22 is slidably arranged on the outer side of the cylindrical slide rail 21. A fixed cylinder 23 is fixedly arranged outside the cylindrical bearing 22. A laser pen 24 is arranged in the fixed cylinder 23, and a control switch 241 is arranged on the laser pen 24;
[0025] Among them, the concrete is placed in the slump bucket 10. By adjusting the lifting column 13, the slump bucket 10 is driven to rise and fall through the ring 12, and is separated from the slump bottom plate 20 and the concrete. The laser pen 24 is started through the control switch 241. Subsequently, the cylindrical bearing 22 is adjusted to drive the fixed cylinder 23 to move on the cylindrical slide rail 21, so that the laser pen 24 measures the height of the concrete. Subsequently, the moving distance of the laser pen 24 on the cylindrical slide rail 21 is measured to ensure that the slump can be accurately calculated.
[0026] It should be noted that the cylindrical bearing 22 can slide up and down on the outer side of the cylindrical slide rail 21, and the cylindrical bearing 22 can be fixed at a specified position through a fixing ring. Among them, the fixed cylinder 23 is fixedly connected with the outer ring of the cylindrical bearing 22, and can drive the laser pen 24 placed in the fixed cylinder 23 to rotate and adjust. Among them, the cylindrical slide rail 21 has the same height as the slump bucket 10, ensuring that the laser pen 24 always maintains a constant vertical distance from the concrete surface during the measurement process, thereby reducing the error introduced due to angle changes and improving the accuracy of the measurement results. The lifting column 13 is provided with a control device (not shown in the figure), which can control multiple lifting columns 13 to rise and fall simultaneously, ensuring the stability when driving the slump bucket 10 to rise and fall through the ring 12 and the rectangular bar 11.
[0027] In this embodiment, the slump bucket 10 is the main part of the device and is used to hold the concrete sample to be tested. Among them, the slump bucket 10 is a conical bucket to ensure that the concrete can slump freely and guarantee the accuracy during measurement. The slump bottom plate 20 is a support platform located below the slump bucket 10 and is used to stabilize the slump bucket 10 and ensure its vertical placement. By fixedly arranging a rectangular bar 11 above the slump bucket 10, it is used to fixedly connect a ring 12. Among them, the ring 12 can connect the lifting column 13 and the slump bucket 10 through the rectangular bar 11, and through cooperation with the lifting column 13, it can effectively drive the slump bucket 10 to adjust its height, separating the slump bucket 10 from the concrete inside, facilitating the slump test. Among them, the lifting column 13 can control the lifting of the slump bucket 10. By controlling the height of the lifting column 13, the distance between the slump bucket 10 and the slump bottom plate 20 can be changed, so that the concrete falls off from the slump bucket 10, facilitating the measurement of the slump. By arranging a cylindrical slide rail 21 on the slump bottom plate 20, it can guide the sliding of the cylindrical bearing 22. Through the arrangement of the cylindrical slide rail 21, the smooth sliding of the cylindrical bearing 22 can be ensured. By sliding the cylindrical bearing 22 outside the cylindrical slide rail 21, it is used to support and fix the fixed cylinder 23 and the laser pen 24 inside it. Among them, the fixed cylinder 23 is fixed outside the cylindrical bearing 22 and is used to accommodate and protect the laser pen 24, ensuring the stability and safety of the laser pen 24 during measurement. Specifically, the setting of the fixed cylinder 23 can not only protect the laser pen 24 from external interference and damage, but also connect the laser pen 24 with the cylindrical bearing 22 to form a stable structure. The laser pen 24 can produce clear laser dots or lines at a long distance and is used to provide a reference line or marking point during the slump measurement. By setting a control switch 241, the laser pen 24 can be conveniently turned on or off to facilitate measuring the highest point after the concrete slumps.
[0028] Preferably, the number of rectangular bars 11 is multiple. By arranging multiple rectangular bars 11 in an array along the center of the slump bucket 10, a more stable structure can be formed, ensuring that the lifting column 13 drives the slump bucket 10 to lift more smoothly, reducing shaking and tilting, and improving the measurement accuracy.
[0029] Preferably, the number of lifting columns 13 is multiple. The multiple lifting columns 13 are respectively arranged on the four sides of the slump bottom plate 20 to ensure uniform force when driving the slump bucket 10 to lift, more evenly dispersing the weight of the slump bucket 10 and improving the stability when the slump bucket 10 moves.
[0030] Preferably, a bottom plate support 25 is fixedly provided at the bottom of the slump bottom plate 20 to support the slump bottom plate 20 and ensure that the slump bottom plate 20 is on the same horizontal plane during use. By arranging the bottom plate supports 25 in an array along the center of the slump bottom plate 20, the stability of the bottom plate during use is improved, a more stable support can be formed, and it helps to reduce the influence of external interference on the measurement results.
[0031] As Figure 2 , Figure 3 shown, a fixing hole 231 is opened above the fixing cylinder 23 for placing the fixing screw 232 and cooperating with the fixing screw 232 to ensure effective fixation of the laser pointer 24, preventing the laser pointer 24 from shaking or shifting during the measurement process, thereby ensuring the stability and accuracy of the measurement results. By threading the fixing screw 232 into the fixing hole 231, the laser pointer 24 can be easily installed and disassembled, facilitating daily maintenance and replacement. At the same time, the thread setting has a certain degree of adjustability, which can adapt to different models and sizes of laser pointers 24, improving the versatility and flexibility of the device.
[0032] The working principle of this utility model is as follows: When slump measurement is required, the concrete to be measured is placed in the slump bucket 10 to fill the slump bucket 10. Subsequently, the lifting column 13 is controlled to rise and fall, and then the slump bucket 10 is driven to rise and fall through the ring 12 and the rectangular bar 11, so that the concrete can slump on the slump bottom plate 20. Subsequently, the laser pointer 24 is started by controlling the switch 241, and the laser beam emitted by the laser pointer 24 is used as the reference line for measurement. Subsequently, by adjusting the cylindrical bearing 22, it drives the fixing cylinder 23 to move on the cylindrical slide rail 21 to ensure that the light beam emitted by the laser pointer 24 acts on the highest point of the concrete, ensuring the accuracy of the measurement results. Finally, by fixing the cylindrical bearing 22, the moving distance of the laser pointer 24 on the cylindrical slide rail 21 can be accurately measured. Combining the known size of the slump bucket 10 and the initial position of the laser pointer 24, the slump of the concrete can be calculated.
[0033] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of this utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of this utility model. The structures, devices, and operation methods not specifically described and explained in this utility model, unless otherwise specified and limited, are implemented according to the conventional means in this field.
