Description

Technical Field

[0001] This utility model relates to the field of concrete mortar testing technology, and in particular to a concrete mortar viscosity measuring instrument. Background Technology

[0002] Concrete mortar viscosity meters are widely used in the construction, building materials, and engineering fields to accurately measure the flowability and viscosity characteristics of concrete or mortar. Their working principle is mostly rotary or vibratory, determining viscosity by measuring the resistance or flow time of the material under specific conditions. They are significant in optimizing concrete mix proportions, ensuring construction quality, and supporting the research and development of new materials. However, current measuring instruments have significant shortcomings. When dealing with high- or low-viscosity materials, the measurement accuracy is poor, and large data errors are prone to occur. Furthermore, after measurement, concrete or mortar residue often remains inside the equipment, making cleaning difficult and interfering with subsequent measurements, thus reducing the accuracy of the results. Improvements are urgently needed to better serve the industry's needs. Utility Model Content

[0003] The main objective of this invention is to provide a concrete mortar viscosity measuring instrument, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A concrete mortar viscosity measuring instrument includes a testing base plate, with support legs fixedly connected to the lower circumference of the base plate. A frame is fixedly connected to the upper left side of the base plate. Limiting grooves are formed on the upper part of the inner front wall and the upper part of the inner rear wall of the frame. A hand-cranked lifting device is threadedly connected to the middle of the upper end of the frame. The lower part of the hand-cranked lifting device is located inside the frame and slidably connected to the two limiting grooves. A threaded bottom frame is fixedly connected to the upper right side of the base plate. An annular groove is formed at the upper end of the threaded bottom frame. A detachable testing structure is threadedly connected to the inner thread of the threaded bottom frame.

[0006] Preferably, the hand-cranked lifting device includes a threaded rod, a crank handle is fixedly connected to the upper end of the threaded rod, a bearing is provided at the lower end of the crank handle, a linkage rod wall is threadedly movably connected to the upper part of the outer surface of the threaded rod, and a limit switch is fixedly connected to both the front and rear parts of the outer surface of the linkage rod wall.

[0007] The block has a mounting frame fixedly connected to the right end of the linkage rod wall, and a rotation measuring instrument assembly is fixedly connected to the middle of the inner lower wall of the mounting frame. The rotation measuring instrument assembly is located directly above the threaded bottom frame seat, and a measuring instrument display is fixedly connected to the right end of the mounting frame.

[0008] By adopting the above technical solution: the crank drives the threaded rod to rotate, causing the linkage rod wall to move up and down. The limit block prevents it from rotating. The mounting frame moves with the linkage rod wall, causing the rotation measuring instrument assembly to move closer to or away from the threaded bottom frame seat for measurement. The measuring instrument display shows the measurement data in real time, which is convenient and practical.

[0009] Preferably, the two limiting blocks are slidably connected within two limiting grooves, and the threaded rod is movably connected to the upper middle part of the frame.

[0010] By adopting the above technical solution: the threaded rod is movably connected to the frame, making it more stable when rotating; the limit block slides in the limit groove, ensuring that the linkage rod wall can only move up and down, making the lifting device operate more precisely.

[0011] Preferably, the rotation measuring instrument assembly includes a servo motor, which is fixedly connected to the inner lower wall of the mounting frame. The output end of the servo motor passes through the middle of the inner lower wall of the mounting frame and is fixedly connected to a connecting column. A circular block is fixedly connected to the lower end of the connecting column. A conical anchor-type stirring blade is fixedly connected to the outer surface of the circular block. A sensor is fixedly connected to the lower end of the conical anchor-type stirring blade.

[0012] By adopting the above technical solution, the servo motor drives the connecting column to rotate, which in turn drives the circular block and the conical anchor-type stirring blades to rotate, thus stirring the material. At the same time, during the stirring process, the sensor can monitor relevant data in real time, making it easier to grasp the material status in a timely manner and improve the accuracy and practicality of the measurement.

[0013] Preferably, the detachable detection structure includes a base block, a threaded block fixedly connected to the lower end of the base block, a concrete measuring cylinder fixedly connected to the upper middle part of the base block, and six baffles fixedly connected in a ring array on the lower part of the outer surface of the base block. The lower middle part of the six baffles is fixedly connected to a ring block, and the threaded block is located inside the ring block.

[0014] By adopting the above technical solution: a concrete measuring cylinder is fixed on the bottom block for measuring concrete, the threaded block facilitates connection with other components, and the baffle and ring block provide protection and support to ensure structural stability. Moreover, the structure is detachable and easy to clean, thereby improving the flexibility of use.

[0015] Preferably, the concrete measuring cylinder has a conical structure and is located directly below the conical anchor-type mixing blade. The inner diameter area of ​​the concrete measuring cylinder is equal to the area of ​​the conical anchor-type mixing blade. The bottom block is detachably connected to the threaded bottom frame seat via a threaded block, and the size of the annular block matches that of the annular groove.

[0016] By adopting the above technical solution: the conical concrete measuring cylinder is adapted to the conical anchor-type mixing blade, which facilitates mixing and measurement; the bottom block is detachably connected to the threaded bottom frame seat through the threaded block, which facilitates the replacement of the measuring cylinder; and the annular block matches the annular groove, which ensures stable installation and improves the accuracy and convenience of measurement operations.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In this utility model, by cranking the handle, the threaded rod is rotated, causing the linkage rod wall to move up and down along the rod, thereby adjusting the height of the mounting frame and the rotating measuring instrument assembly. This facilitates the measurement of concrete mortar at different locations. The limiting block slides within the limiting groove, ensuring the stability and accuracy of the linkage rod wall movement and preventing shaking from affecting the measurement results. In the rotating measuring instrument assembly, the servo motor drives the connecting column, the circular block, and the conical anchor-type stirring blade to rotate, which can fully stir the material, allowing the sensor to measure more accurate material viscosity data. The measuring instrument display can show the measurement results in real time, making it convenient for operators to read. Overall, this structure is simple to operate and can effectively improve the accuracy and efficiency of measurement.

[0019] 2. In this utility model, the threaded connection allows for easy installation and disassembly of the base frame, facilitating thorough cleaning of the measuring cylinder after measurement to prevent residual substances from affecting subsequent measurement results and effectively improving measurement accuracy. The conical measuring cylinder is compatible with the stirring blade, allowing the stirring blade to better penetrate the cylinder and stir the material, ensuring uniform mixing and making the measurement data more representative. The annular block matches the annular groove, providing good positioning and support for installation, enhancing structural stability, and ensuring that the device will not shake or shift during measurement, thus guaranteeing the smooth progress of the measurement work.

Those skilled in the art can understand this according to the specific circumstances.

[0028] The specific meanings of the above terms in this utility model.

[0029] Please refer to Figures 1-4. This utility model provides a technical solution:

[0030] A concrete mortar viscosity measuring instrument includes a testing base plate 1. Support legs 2 are fixedly connected to the lower end of the testing base plate 1 around its perimeter. A frame 3 is fixedly connected to the upper left part of the testing base plate 1. Limiting grooves 4 are opened on the upper part of the inner front wall and the upper part of the inner rear wall of the frame 3. A hand-cranked lifting device 5 is threadedly connected to the middle part of the upper end of the frame 3. The lower part of the hand-cranked lifting device 5 is located inside the frame 3 and is slidably connected to the two limiting grooves 4. A threaded bottom frame 6 is fixedly connected to the upper right part of the testing base plate 1. An annular groove 7 is opened on the upper end of the threaded bottom frame 6. A detachable testing structure 8 is threadedly connected to the inner thread of the threaded bottom frame 6.

[0031] In this embodiment, the hand-cranked lifting device 5 includes a threaded rod 51, with a crank handle 52 fixedly connected to the upper end of the threaded rod 51. A bearing 53 is provided at the lower end of the crank handle 52. A linkage rod wall 54 is threadedly and movably connected to the upper part of the outer surface of the threaded rod 51. Limit blocks 55 are fixedly connected to both the front and rear parts of the outer surface of the linkage rod wall 54. A mounting frame 56 is fixedly connected to the right end of the linkage rod wall 54. A rotation measuring instrument assembly 57 is fixedly connected to the middle of the inner lower wall of the mounting frame 56. The rotation measuring instrument assembly 57 is located directly above the threaded bottom frame seat 6. A measuring instrument display 58 is fixedly connected to the right end of the mounting frame 56. Two limit blocks 55 are slidably connected within two limit grooves 4. The threaded rod 51 is movably connected to the middle of the upper end of the frame frame 3. The rotation measuring instrument assembly 57 includes a servo motor 571, which is fixedly connected to the inner lower wall of the mounting frame 56. The output end passes through the middle of the inner lower wall of the mounting frame 56 and is fixedly connected to a connecting column 572. A round block 573 is fixedly connected to the lower end of the connecting column 572. A conical anchor-type stirring blade 574 is fixedly connected to the outer surface of the round block 573. A sensor 575 is fixedly connected to the lower end of the conical anchor-type stirring blade 574.

[0032] Through the above scheme: the operator turns the crank handle 52, causing the threaded rod 51 to rotate. Because the limiting block 55 slides within the limiting groove 4, the linkage rod wall 54 can only move up and down along the threaded rod 51, thus moving the mounting frame 56 and the rotation measuring instrument assembly 57 closer to or further away from the object being measured. This activates the servo motor 571, whose output drives the connecting column 572, the circular block 573, and the conical anchor-type stirring blade 574 to rotate. The sensor 575 then measures...

[0033] The data is transmitted to the measuring instrument display 58. The conical anchor-type stirring blade 574 can effectively stir materials of different viscosities, making the measurement more comprehensive and accurate. The limiting block 55 and the limiting slide 4 ensure the accuracy of the measurement position and reduce data errors caused by shaking, thus solving the problem of poor accuracy of traditional measuring instruments when measuring materials of different viscosities.

[0034] In this embodiment, the detachable detection structure 8 includes a base block 81, a threaded block 83 fixedly connected to the lower end of the base block 81, a concrete measuring cylinder 82 fixedly connected to the middle of the upper end of the base block 81, six baffles 84 fixedly connected in a ring array on the lower part of the outer surface of the base block 81, and a ring block 85 fixedly connected to the middle of the lower end of the six baffles 84. The threaded block 83 is located inside the ring block 85. The concrete measuring cylinder 82 has a conical structure and is located directly below the conical anchor mixing blade 574. The inner diameter area of ​​the concrete measuring cylinder 82 is equal to the area of ​​the conical anchor mixing blade 574. The base block 81 is detachably connected to the threaded bottom frame seat 6 through the threaded block 83. The size of the ring block 85 matches that of the ring groove 7.

[0035] The above solution allows for the following: When concrete measurement is required, the bottom block 81 is connected to the threaded bottom frame seat 6 via the threaded block 83, while the annular block 85 is embedded in the annular groove 7 to ensure a stable connection. Concrete is then placed into the concrete measuring cylinder 82, and the conical anchor-type mixing blade 574 rotates to measure. After measurement, the bottom block 81 is rotated to separate the threaded block 83 from the threaded bottom frame seat 6, allowing the detachable detection structure 8 to be removed as a whole. This makes it easy to remove and clean the concrete measuring cylinder 82, which may contain residual concrete or mortar, preventing residual substances from interfering with subsequent measurements. The conical structure of the concrete measuring cylinder 82 is compatible with the conical anchor-type mixing blade 574, ensuring measurement effectiveness and facilitating cleaning, thus effectively improving the accuracy of the measurement results and meeting industry requirements.

[0036] It should be noted that this utility model is a concrete mortar viscosity measuring instrument. During use, firstly, concrete or mortar is poured into the concrete measuring cylinder 82 of the detachable testing structure 8. The bottom block 81 is then installed onto the threaded bottom frame seat 6 via the threaded block 83, allowing the annular block 85 to embed into the annular groove 7, ensuring a stable connection. Rotating the handle 52 of the hand-cranked lifting device 5 causes the threaded rod 51 to rotate. Because the limiting block 55 slides within the limiting groove 4, the linkage rod wall 54 moves up and down along the threaded rod 51, thereby adjusting the height of the mounting frame 56 and the rotating measuring instrument assembly 57, allowing the conical anchor-type stirring blade 574 to enter...

[0037] The concrete measuring cylinder 82 starts the servo motor 571 of the rotating measuring instrument assembly 57, whose output drives the connecting column 572, the circular block 573 and the conical anchor-type stirring blade 574 to rotate. The sensor 575 measures the viscosity data of the concrete or mortar and transmits it to the measuring instrument display 58 for display. After the measurement is completed, the bottom block 81 is rotated to separate the threaded block 83 from the threaded bottom frame seat 6, and the detachable detection structure 8 is removed as a whole for cleaning. Therefore, the measuring position can be accurately adjusted by the hand-cranked lifting device 5, the rotating measuring instrument assembly 57 accurately measures the viscosity data, and the detachable detection structure 8 is convenient for cleaning and maintenance. This effectively solves the problems of measurement accuracy and cleaning, and can provide an accurate and convenient solution for the measurement of concrete and mortar viscosity.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
