[0023] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below with reference to specific illustrations.
[0024] Refer to Figures 1-6As shown in the figure, a torque method concrete strength estimator includes an instrument body 1. At the output end of the instrument body 1, there is an installation part 2 for installing and connecting a stirring rod 3, and the axis of the stirring rod 3 is collinear with the axis of the installation part 2. During use, one end of the stirring rod 3 is connected to the installation part 2, and the installation part 2 will clamp and fix the stirring rod 3. Then, the instrument body 1 will drive the installation part 2 to rotate, thereby driving the stirring rod 3 to rotate. A plurality of paddles 301 are fixedly connected to the end of the stirring rod 3 away from the installation part 2. When the paddles 301 are inserted into the concrete and rotated, resistance will be generated, and then it will be transmitted to the instrument body 1 through the stirring rod 3.
[0025] When the longer stirring rod 3 rotates, since resistance will be generated at one end during rotation, the stirring rod 3 itself will shake during rotation, thereby affecting the vibration of the instrument body 1 accordingly. To reduce the shaking amplitude of the stirring rod 3 itself and limit the rotating stirring rod 3, a telescopic member 4 that reciprocates along the axis of the installation part 2 is provided on the instrument body 1, and the moving direction of the movable end of the telescopic member 4 is parallel to the axis direction of the installation part 2. A limiting member 5 is connected to the movable end of the telescopic member 4. The limiting member 5 is located at the end of the installation part 2 away from the instrument body 1. One end of the stirring rod 3 passes through the limiting member 5 and is connected to the installation part 2, and the limiting member 5 is in contact with the stirring rod 3. The stirring rod 3 will rotate on the limiting member 5 during rotation, and an auxiliary assembly for assisting the movement and fixation of the telescopic member 4 is provided on the telescopic member 4.
[0026] When the above structure is in use, the movable end of the telescopic member 4 is driven to move through the auxiliary assembly, and then the limiting member 5 connected to its movable end moves on the stirring rod 3, and the telescopic member 4 will drive the limiting member 5 to move to different positions on the stirring rod 3. When the end of the stirring rod 3 with the paddles 301 rotates in the concrete, the longer the stirring rod 3, the greater the amplitude of the lateral vibration generated. After using the limiting member 5, the stirring rod 3 will rotate on the limiting member 5, and the limiting member 5 plays a role in limiting and assisting the stirring rod 3, so that the shaking amplitude of the stirring rod 3 is reduced during rotation, helping the instrument body 1 to control the stirring rod 3.
[0027] The above-mentioned instrument body 1 is a prior art structure. Refer to Figure 1As shown in the figure, the instrument body 1 mainly includes a battery 101 that provides power for the instrument body 1, a handle 102 for easy holding, a stirring switch 103 that starts the rotation of the installation part 2 of the instrument body 1, a temperature sensor 104 arranged on the instrument body 1, a display screen 105 arranged on the instrument body 1, a power switch 106 for the display screen 105, and an operating system (not shown in the figure) arranged inside the instrument body 1. Specifically, use the power switch 106 to start the display screen 105, and the display screen 105 can display some operation instructions of the operating system, which is convenient for the user to observe. Then install the stirring rod 3 on the installation part 2. The installation part 2 is a structure for the instrument body 1 to clamp and fix the stirring rod 3. Start the stirring switch 103, and then the installation part 2 rotates. During this process, the battery 101 continuously provides power for the operation of the instrument body 1, and the temperature sensor 104 collects the temperature change of the concrete to be detected and displays it on the display screen 105. The data generated when the stirring rod 3 rotates will be displayed on the display screen 105 in real time. Finally, under the calculation of the operating system, the final data will be displayed on the display screen 105.
[0028] The main function of the instrument body 1 is to input the relevant data of the materials used in the concrete to be detected into the instrument body 1. Then the instrument body 1 will adjust to the inspection method matching the concrete. Next, insert one end of the stirring rod 3 into the installation part 2 of the instrument body 1, and then insert the other end of the stirring rod 3 into the concrete to be detected. Then the internal motor system of the instrument applies torque to the concrete sample through the stirring rod 3, and calculates the relevant data of the concrete according to a specific conversion formula. According to the current output by the collected motor system, the strength, temperature, and slump of the concrete are measured.
[0029] Refer to Figure 6 As shown in the figure, further, the telescopic member 4 is composed of a telescopic tube 401 fixedly connected to the instrument body 1 and a movable rod 402 slidably connected to the telescopic tube 401. In order to ensure the stability of the limiting member 5, multiple groups of telescopic members 4 can be arranged on the instrument body 1. The limiting member 5 is connected to one end of the movable rod 402 away from the telescopic tube 401. A long hole 6 is opened on the side surface of the telescopic tube 401 away from the instrument body 1. The movable rod 402 can be observed through the long hole 6 outside the telescopic tube 401. When the telescopic member 4 is in use, the movable rod 402 will slide back and forth on the telescopic tube 401.
[0030] Refer to Figure 6As shown, further, the limiting member 5 is in the shape of a ring, and the inner wall of the limiting member 5 in the shape of the ring is in active contact with the outer surface of the stirring rod 3, and the outer wall of the limiting member 5 in the shape of the ring is fixedly connected to the movable rod 402 through the connecting rod 7. When the stirring rod 3 rotates, it rotates on the inner wall of the limiting member 5 in the shape of the ring, and the limiting member 5 in the shape of the ring assists the rotation of the stirring rod 3, thereby reducing the lateral shaking of the stirring rod 3 caused by obstruction.

When in use, the movable bolt 9 is threadedly connected to the threaded hole 8. At this time, the movable bolt 9 is in close contact with the outer wall of the telescopic tube 401, and the friction between the movable bolt 9 and the telescopic tube 401 makes the movable rod 402 fastened to the telescopic tube 401. When you want to move the movable rod 402, you only need to twist the movable bolt 9 so that it is no longer in close contact with the outer wall of the telescopic tube 401, and then you can move the movable rod 402.
[0032] Among them, in order to make the contact between the movable bolt 9 and the outer wall of the telescopic tube 401 closer, increase the friction between the two, and make the movable rod 402 more secure when tightened, an anti-skid pad 10 is fixedly connected to the outer wall of the telescopic tube 401 and located on the side of the long hole 6, and an anti-skid pad 2 11 is fixedly connected to the side where the movable bolt 9 contacts the outer wall of the telescopic tube 401, and the anti-skid pad 10 is in movably contact with the anti-skid pad 2 11, and the contact and separation between the movable bolt 9 and the telescopic tube 401 is the release and separation between the anti-skid pad 10 and the anti-skid pad 2 11.
[0033] Reference Figures 4-5 As shown, a second embodiment of the auxiliary component of the utility model is that the auxiliary component includes a rack portion 12 opened on the movable rod 402, a gear box 15 connected to the rack portion 12, and a drive motor 13 driving the gear box 15 to operate. The rack portion 12 is located at a position corresponding to the long hole 6, and the drive motor 13 is connected to the instrument body 1. The instrument body 1 provides power input for the drive motor 13. At the same time, the instrument body 1 can also be used to control the start and stop of the drive motor 13. The drive motor 13 drives the rack portion 12 to move through the gear box 15, thereby controlling the forward and backward movement of the movable rod 402.
[0034] Among them, the gear 15 box includes a box body 14 fixedly connected to the telescopic tube 401, a gear 15 rotatably connected inside the box body 14, a bevel gear 16, and a bevel gear 17. The gear 15 is fixedly connected to the bevel gear 16, the gear 15 meshes with the rack portion 12, the bevel gear 16 meshes with the bevel gear 17, and the bevel gear 17 is connected to the output end of the driving motor 13. When the above structure is in use, the driving motor 13 drives the bevel gear 17 to rotate, thereby driving the meshing bevel gear 16 to rotate, and then driving the gear 15 fixedly connected to the bevel gear 16 to rotate. The rotating gear 15 drives the movement of the rack portion 12. Finally, the driving motor 13 controls the movement of the movable rod 402 through the bevel gear 17, the bevel gear 16, the gear 15, and the rack portion 12.
[0035] The advantage of the second embodiment of the auxiliary component of the present invention compared to the first embodiment of the auxiliary component of the present invention is that in the first embodiment, the movable rod 402 is moved and fixed manually, while in the second embodiment, the instrument body 1 controls the operation of the driving motor 13.
