Description

Technical Field

[0001] This utility model relates to the field of detection device technology, specifically a high-precision stirring shaft lifting device. Background Technology

[0002] The concrete mortar rheometer is mainly used to measure the rheological properties of ready-mixed mortar, such as plastic viscosity, yield stress, and maximum yield stress. These parameters are of great significance for evaluating the workability of concrete, optimizing concrete mix proportions, and improving concrete quality and performance. The mixing shaft lifting device is designed to meet the high-precision measurement requirements of concrete mortar rheological properties.

[0003] Referring to the patent application with authorization publication number CN219084692U, a smart concrete rheometer is disclosed. The device includes a base, a frame housing, a rotating testing mechanism, a rheology barrel, an electrical control box, and a moving mechanism. The frame housing is connected to the base. The electrical control box and the moving mechanism are installed inside the frame housing. The electrical control box and the moving mechanism are communicatively connected, and the electrical control box can control the operation of the moving mechanism. The rotating testing mechanism is located on one side of the frame housing, and a slider on the moving mechanism extends out of the frame housing and is connected to the rotating testing mechanism. The moving mechanism can push the rotating testing mechanism to perform lifting and lowering movements. The rotating testing mechanism is communicatively connected to the electrical control box. A positioning block is provided on the base, and the rheology barrel is placed on the base, with the positioning block used to limit the position of the rheology barrel.

[0004] However, the above-mentioned technology uses a moving mechanism to drive the rotating measuring mechanism to lift and lower for subsequent testing. When the device is in use, the mix ratio, particle size, viscosity and other characteristics of the concrete mortar change significantly. This requires the mixing shaft to be replaced to improve the mixing effect. However, the existing device is not convenient for replacing the mixing shaft, so its practicality is generally limited.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] See Figures 1-5 This utility model provides two technical solutions:

[0025] First embodiment: A high-precision stirring shaft lifting device, including a base 1, and further comprising:

[0026] The testing mechanism 2 is set on the top surface of the base 1 to test the rheological properties of mortar, such as plastic viscosity and yield stress. The testing mechanism 2 includes a groove plate 29 fixedly installed on the rear side of the top surface of the base 1. A connecting frame 28 is movably installed on the front side of the groove plate 29. A connecting seat 26 is movably installed inside the connecting frame 28. A torque sensor 27 for testing the rheological properties of mortar is fixedly installed inside the connecting frame 28. The model of the torque sensor 27 is not specifically required, as long as it can detect the amount of torsion when the connecting seat 26 rotates. A stirring shaft body 24 is movably installed on the bottom surface of the connecting seat 26. A connecting component is provided on the top surface of the stirring shaft body 24 for connecting and fixing with the connecting seat 26, and for facilitating the disassembly and replacement of the stirring shaft body 24.

[0027] The lifting mechanism 3 is located on the top surface of the base 1 to adjust the height of the connecting frame 28 for easy mortar testing. The connecting assembly includes a locking block 25 fixedly installed on the bottom surface of the mixing shaft body 24 to position the mixing shaft body 24. The locking block 25 has a convex cross-section. The front side of the connecting seat 26 has a locking groove 212, and the right side of the connecting seat 26 has a movable groove 210. The movable groove 210 is movably installed with an insert block 214 for fixing the position of the locking block 25. The right side of the insert block 214 is fixed. A pull plate 211 is installed to facilitate the pulling of the insert block 214. A spring 213 for fixing the position of the insert block 214 is fixedly installed on the top surface of the insert block 214. A slot 215 is opened on the top surface of the locking block 25. The outer side of the locking block 25 is tightly attached to the inner side of the slot 212. The locking block 25 can be positioned by the slot 212 to position the stirring shaft body 24. The top end of the spring 213 is fixedly installed on the top surface of the movable groove 210. The bottom end of the insert block 214 moves through the interior of the movable groove 210 and extends to the slot 215. Inside the base 15, the bottom end of the torque sensor 27 is fixedly installed on the top surface of the connecting seat 26. The spring force of the spring 213 will drive the insert block 214 to insert into the slot 215 and fix the position of the locking block 25. The detection mechanism 2 also includes a placement plate 23 movably installed on the front side of the top of the base 1 for placing and fixing the rheology barrel. The placement plate 23 has locking blocks around its top surface for fixing the position of the rheology barrel. A brushless motor 21 for driving the placement plate 23 to rotate is fixedly installed on the bottom surface of the inner cavity of the base 1. A data processing module 22 for processing the data detected by the torque sensor 27 is fixedly installed on the rear side of the bottom surface of the inner cavity of the base 1. The model of the data processing module 22 is not specifically required, as long as it can integrate the data detected by the torque sensor 27 for analysis. The output end of the brushless motor 21 moves through the interior of the base 1 and is fixedly installed on the bottom surface of the placement plate 23. Starting the brushless motor 21 can drive the placement plate 23 to rotate the rheology barrel, which is convenient for subsequent detection of mortar rheological performance parameters.

[0028] The set locking block 25 and insert block 214 facilitate the replacement of the stirring shaft body 24. When the stirring shaft body 24 needs to be replaced, pull the pull plate 211 to drive the insert block 214 out of the slot 215, and then remove the stirring shaft body 24. Then pick up the appropriate stirring shaft body 24, insert the locking block 25 into the locking groove 212, and then release the locking groove 212. The elastic force of the spring 213 will drive the insert block 214 into the slot 215. The locking block 25 fixes the position of the stirring shaft body 24, which is convenient for replacement and has good practicality.

[0029] The second embodiment differs from the first embodiment in that: the lifting mechanism 3 includes a mounting bracket 33 fixedly installed on the rear side of the slot plate 29; a driven gear 35 and a driving gear 36 are movably installed on the top surface of the inner cavity of the mounting bracket 33; a DC motor 38 for driving the driving gear 36 to rotate is fixedly installed on the front side of the inner cavity of the mounting bracket 33; a connecting block 32 for fixing the position of the connecting bracket 28 is movably installed inside the slot plate 29; a screw 31 for adjusting the height of the connecting block 32 is movably installed inside the slot plate 29; a belt 34 for driving the driven gear 35 to rotate is movably installed on the outer side of the driving gear 36; and a laser sensor 37 for detecting the position of the connecting bracket 28 is fixedly installed on the left end of the front side of the mounting bracket 33, and the signal of the laser sensor 37 is not specifically required. It is sufficient to detect whether the connecting bracket 28 has reached the accurate position. The left and right sides of the front side of the connecting block 32 are movable through the interior of the slot plate 29 and fixedly installed on the rear side of the connecting bracket 28. The bottom end of the screw 31 is threaded through the top surface of the connecting block 32 and is movablely installed on the bottom surface of the inner cavity of the slot plate 29. The top end of the screw 31 is movable through the interior of the slot plate 29 and is fixedly installed on the bottom surface of the driven gear 35. The output end of the DC motor 38 is fixedly installed on the bottom surface of the driving gear 36. The inner side of the belt 34 is close to the outer side of the driven gear 35. Starting the DC motor 38 can drive the driving gear 36 to rotate. Then the driving gear 36 will drive the driven gear 35 to rotate through the belt 34. At this time, the driven gear 35 will drive the screw 31 to rotate to adjust the height of the connecting block 32.

[0030] The screw 31 and laser sensor 37 allow for easy adjustment of the position of the connecting frame 28. In use, the DC motor 38 is started to drive the drive gear 36 to rotate. The drive gear 36 then drives the driven gear 35 to rotate via the belt 34. The driven gear 35 then drives the screw 31 to rotate, adjusting the height of the connecting block 32. When the connecting block 32 moves the connecting frame 28 to the appropriate position, the laser sensor 37 detects the position of the connecting frame 28. Turning off the DC motor 38 then fixes the position of the connecting frame 28. Precise control of the connecting frame 28's position facilitates subsequent stirring and testing, improving stirring efficiency and enhancing practicality.

[0031] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0032] In use, the user places the converter bucket on the top surface of the placement plate 23 for fixation. Then, the DC motor 38 is started to drive the drive gear 36 to rotate. The drive gear 36 then drives the driven gear 35 to rotate via the belt 34. At this time, the driven gear 35 drives the screw 31 to rotate to adjust the height of the connecting block 32. When the connecting block 32 drives the connecting frame 28 to insert the stirring shaft body 24 into the converter bucket, the laser sensor 37 will detect the position of the connecting frame 28. Then, the DC motor 38 is turned off to fix the position of the connecting frame 28. Next, the brushless motor 21 is started to drive the placement plate 23 to rotate the converter bucket. At this time, the mortar in the converter bucket will push the stirring shaft body 24 to generate rotational force. When the torque sensor 27 is twisted by the rotational torque, the spline and key... The relative position of the groove is changed, and the change in its relative displacement is the torsion. This change will change the magnetic field strength on the spline. The change in magnetic field strength is converted into a voltage signal by the coil and sent to the data processing module 22 for analysis. The rheological performance parameters such as the plastic viscosity and yield stress of the mortar are analyzed. When it is necessary to replace the stirring shaft body 24, pull the pull plate 211 to drive the insert block 214 out of the slot 215. Then, remove the stirring shaft body 24. Then, pick up the appropriate stirring shaft body 24 and insert the locking block 25 into the slot 212. Then, release the slot 212. The elastic force of the spring 213 will drive the insert block 214 into the slot 215. The position of the stirring shaft body 24 is fixed by the locking block 25, and subsequent testing can be carried out.
