If the data obtained by the measuring rod contacting with the concrete specimen during the test is inevitably inaccurate, it will also lead to the problem that the concrete shrinkage data finally obtained is inaccurate; and the dust cleaning mechanism can blow air to the contact position between the leveling frame and the concrete specimen to be tested, blow off the floating dust on the surface, and achieve the effect of cleaning the floating dust, thereby improving the accuracy of the test;

[0038] The present invention provides the following embodiments

[0039] Example 1

[0040] The embodiment of the present invention provides a slag concrete shrinkage test device, such as Figure 1-8 As shown, it includes a test device 1 and a comparison device 2, and both the test device 1 and the comparison device 2 include a sealing cover 3, a shrinkage test execution component and an environmental adjustment component;

[0041] The shrinkage test execution component includes a placement table 4, a mounting table 1 5 and a mounting table 2 6. The placement table 4 is used to place a concrete block 100. A positioning block 400 is provided on one side of the placement table 4. The mounting table 1 5 and the mounting table 2 6 are respectively installed on the side and the top of the placement table 4. The mounting table 1 5 and the mounting table 2 6 are both used to install any one of the micrometers 7 or the pressure blocks 8.

[0042] Preferably, both the test device 1 and the comparison device 2 are provided with an image acquisition component 206 .

[0043] The working principle and beneficial effects of the above technical solution are as follows: during the test, the concrete block 100 is placed on the placement table 4, one side of which is against the positioning block 400. When the side shrinkage test is performed, the dial gauge 7 is installed on the mounting table 1 5. Before the test, the detection end of the dial gauge 7 is against the side of the concrete block 100. Then the environmental adjustment component is turned on, and the sealing cover 3 is sealed. The environmental adjustment component is adjusted so that the ambient temperature, humidity and light in the sealing cover 3 are adjusted to preset values. After waiting for the preset test time, the side shrinkage rate of the concrete block 100 is calculated through the value change of the dial gauge 7. During the test, the height of the dial gauge 7 can be adjusted arbitrarily. At this time, if load-bearing simulation is required, the pressure block 8 is installed on the mounting table 2 6. During the test, the pressure block 8 is against the top surface of the concrete block 100. The actual load-bearing of the concrete block 100 can be simulated by adjusting the height of the pressure block 8.

[0044] When performing the top shrinkage test, the micrometer 7 is installed on the mounting platform 2 6. Before the test, the detection end of the micrometer 7 is against the top surface of the concrete block 100. Then, the environmental adjustment component is opened, and the sealing cover 3 is sealed. The environmental adjustment component is adjusted so that the ambient temperature, humidity and light in the sealing cover 3 are adjusted to the preset values. After waiting for the preset test time, the top surface shrinkage rate of the concrete block 100 is calculated through the value change of the micrometer 7.

[0045] During the test, concrete blocks 100 of the same specifications are placed in the test device 1 and the comparison device 2 respectively. The concrete blocks 100 in the test device 1 are subjected to a normal shrinkage test, and the concrete blocks 100 in the comparison device 2 are humidified by the auxiliary curing mechanism during the shrinkage test, thereby obtaining the optimal curing humidity of the concrete blocks 100.

[0046] The present invention can flexibly adjust the height of the micrometer 7 according to the volume of the test concrete through the adjustable installation of the micrometer 7 on the mounting platform 1 5. The design of the mounting platform 1 5 satisfies the measurement of the shrinkage rate of the concrete block 100 in the horizontal direction. The design of the mounting platform 2 6 satisfies the measurement of the shrinkage rate of the concrete block 100 in the vertical direction. The test results are comprehensive. The design of the environmental adjustment component and the sealing cover 3 realizes the real environment simulation, so that the final test data has substantial reference value. The design of the mounting platform 2 6 and the pressure block 8 can simulate the pressure condition of the concrete in the real use environment, so as to ensure the reference value of the final test data.

A connecting ventilation port is provided on the upper surface of the equipment base 101, and the temperature control mechanism and the humidity control mechanism are connected to the connecting ventilation port.

[0049] The working principle and beneficial effects of the above technical solution are as follows: after the environmental adjustment component is turned on, the temperature control mechanism and the humidity control mechanism adjust the ambient temperature and ambient humidity in the sealing cover 3 by connecting the ventilation port, and at the same time, the light simulation mechanism 102 adjusts the ambient light intensity in the sealing cover 3, thereby simulating the real drying environment of concrete and ensuring the reliability of the final test data.

[0052] The working principle and beneficial effects of the above technical solution are as follows: when adjusting the height of the micrometer 7 or the pressure block 8, the electric vertical adjustment screw 502 rotates to drive the vertical adjustment nut 503 to move up and down, thereby driving the micrometer 7 or the pressure block 8 to move up and down, thereby realizing the adjustment of the height of the micrometer 7 or the pressure block 8 and improving the flexibility of the test equipment.

[0056] The working principle and beneficial effects of the above technical solution: when adjusting the height of the mounting platform 2 6, the height can be roughly adjusted by the coarse adjustment cylinder 200 first, and then the height of the mounting platform 2 6 can be finely adjusted by the fine adjustment cylinder 204. The linear motor 202 can realize the left and right adjustment of the fine adjustment cylinder mounting seat 203, thereby realizing the left and right adjustment of the fine adjustment cylinder 204 and the mounting platform 2 6. The design of the U-shaped mounting frame 205 improves the irradiation breadth of the light simulation mechanism 102.

The placing table 4 is fixedly connected to the placing table adjustment nut 403, and the bottom of the placing table 4 is slidably connected to the screw mounting platform 402 through a guide slider 404.

[0060] The working principle and beneficial effects of the above technical solution are as follows: when adjusting the position of the placement table 4, the placement table electric adjustment screw 401 rotates to drive the placement table adjustment nut 403 to move, and the placement table adjustment nut 403 moves to drive the placement table 4 to move. During the movement of the placement table 4, the guide slider 404 can stabilize the placement table 4.

[0061] Example 6

[0062] On the basis of embodiment 5, it further includes a foundation simulation mechanism 9, and the foundation simulation mechanism 9 is bolted to the placement platform 4 through mounting bolts 900;

[0063] The foundation simulation mechanism 9 includes a foundation simulation mechanism shell 901 and a foundation simulation component. The foundation simulation component is arranged in the foundation simulation mechanism shell 901. A T-type stage 905 is slidably connected to the foundation simulation mechanism shell 901. The T-type stage 905 and the foundation simulation mechanism shell 901 are connected via a connecting elastic member 902. Two groups of symmetrically arranged electric lifting cams 903 are rotatably connected to the foundation simulation mechanism shell 901. The electric lifting cams 903 are used to cooperate with the cam matching groove 904 at the bottom of the T-type stage 905.

[0064] The working principle and beneficial effects of the above technical solution are as follows: when more accurate shrinkage test data is needed, the foundation simulation can be performed on the concrete block 100, the foundation simulation mechanism 9 is bolted to the placement table 4 through the mounting bolts 900, the concrete block 100 is placed on the T-shaped stage 905, and then the electric lifting cam 903 is rotated to adjust the height of the T-shaped stage 905. During the adjustment process, the T-shaped stage 905 moves up and down in the foundation simulation mechanism housing 901.

[0065] Example 7

[0066] Based on Example 6, the foundation simulation component includes left and right clamping components and front and rear clamping components;

[0067] The left and right clamping components include left and right bidirectional electric lead screws 9000, which are rotatably connected to the T-type platform 905, and left and right bidirectional electric lead screws 9000 are threadedly connected to left and right clamping nuts 9001, and left and right clamping plates 9002 are installed on the left and right clamping nuts 9001;

[0068] The front and rear clamping components include two symmetrically arranged front and rear bidirectional electric lead screws 9003, which are rotatably connected in the foundation simulation mechanism housing 901, and the front and rear bidirectional electric lead screws 9003 are threadedly connected with two symmetrically arranged front and rear clamping nuts 9004, both of which are slidingly connected in the foundation simulation mechanism housing 901, and both of the front and rear clamping nuts 9004 are rotatably connected with a swing arm 9005, and the other end of the swing arm 9005 is hingedly connected to a miniature nut 9006, and the miniature nut 9006 is threadedly connected to an electric miniature lead screw 9007, and the electric miniature lead screw 9007 is rotatably connected to a lead screw mounting block 9008, and the two lead screw mounting blocks 9008 corresponding to the two front and rear clamping nuts 9004 are respectively installed on the front clamping plate 9009 and the rear clamping plate 9010.

[0069] The working principle and beneficial effects of the above technical solution are as follows: when working, the left and right clamping components and the front and rear clamping components clamp the four sides of the concrete block 100 at the same time, thereby realizing foundation simulation;

[0070] When the left and right sides are clamped, the left and right bidirectional electric lead screws 9000 rotate to drive the left and right clamping nuts 9001 to move, and the movement of the left and right clamping nuts 9001 drives the two left and right clamping plates 9002 to move toward each other until they contact the left and right sides of the concrete block 100;

At first, the left and right holding plates 9002 are in the same plane with the top surface of the foundation simulation mechanism shell 901, and the foundation simulation mechanism shell 901 is in a sealed state. When the concrete block 100 needs to be placed, the foundation simulation mechanism shell 901 is opened. During the opening process, the electric micro screw 9007 rotates to drive the micro nut 9006 to move, and the movement of the micro nut 9006 drives the swing arm 9005 to rotate. The swing arm 9005 rotates to pull the screw mounting block 9008 downward, and the screw mounting block 9008 moves downward to drive the front holding plate 9007 to move. After the front and rear clamping plates 9009 and 9010 move downward to a preset distance below the notch provided on the top surface of the foundation simulation mechanism housing 901, the bidirectional electric lead screw 9003 rotates to drive the two front and rear clamping nuts 9004 to move back to back, thereby making the two front clamping plates 9009 and the rear clamping plates 9010 move back to back. After moving back to back to a suitable distance, the concrete block 100 is placed on the T-type stage 905. After that, the bidirectional electric lead screw 9003 rotates to drive the two front and rear clamping nuts 9004 to move toward each other until they abut against the front and rear side surfaces of the concrete block 100, thereby achieving the clamping of the concrete block 100 in the front and rear directions;

[0072] The design of the foundation simulation component can simulate the part of the concrete block 100 located below the foundation, the pressure block 8 can simulate the pressure-bearing state of the concrete block 100, and the environmental adjustment component can simulate the real environmental state of the concrete block 100, thereby increasing the reliability of the test data.
