Description

Technical Field

[0001] The utility model relates to the technical field of concrete detection, in particular to a concrete slump detection device. Background Art

[0002] The slump of concrete needs to be tested before use. A slump tester is used, which consists of a slump cone, a funnel, a ruler, and a tamping rod. It is suitable for slump tests on plastic concrete with a slump of 1cm-15cm and a maximum aggregate size of no more than 40cm.

[0003] When testing the slump of concrete, the concrete is placed inside a test cylinder, and then the height of the test cylinder is determined. The test cylinder is removed, and after a period of sedimentation, the height of the concrete after it has fallen is confirmed and compared with the initial height. The slump of the concrete can be determined. However, when confirming the initial height, the scale and the test cylinder need to be aligned with each other. The scale and the test cylinder cannot be aligned quickly, resulting in reduced detection efficiency. Utility Model Content

[0019] The embodiment of the present application solves the problems in the prior art by providing a concrete slump detection device. A support assembly is provided, and the support assembly includes a sliding rod. A limit cover is provided at the top of the sliding rod, and the cross-sectional diameter of the limit cover is larger than the cross-sectional diameter of the sliding rod. When measuring the elevation of the detection cylinder, the calibration assembly on the outer wall of the sliding rod is moved upward so that the calibration assembly and the lower surface of the limit cover are in contact with each other. In this way, the lower surface of the calibration ruler inside the calibration assembly is flush with the upper surface of the detection cylinder, so that the height of the detection cylinder can be quickly determined, thereby improving the efficiency of use.

[0020] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0021] Embodiment 1:

[0022] This embodiment provides a specific structure of a concrete slump detection device, such as Figure 1-4 As shown, it includes a detection cylinder 1 for containing concrete and a calibration component 3 arranged on one side of the detection cylinder 1, which is used to measure the size of the detection cylinder 1. The detection cylinder 1 is a hollow truncated cone structure, and the cross-sectional diameter of the top ring of the detection cylinder 1 is smaller than the cross-sectional diameter of the bottom ring;

[0023] Among them, a support assembly 2 is provided at one end of the calibration assembly 3 away from the detection cylinder 1. The support assembly 2 and the calibration assembly 3 are slidably connected. The calibration assembly 3 is limited by the support assembly 2. When measuring the elevation of the detection cylinder 1, the calibration assembly 3 on the outer wall of the sliding rod 22 is moved up, so that the calibration assembly 3 and the lower surface of the limiting cover 23 are in contact with each other. In this way, the lower surface of the calibration ruler 33 inside the calibration assembly 3 is flush with the upper surface of the detection cylinder 1, so that the height of the detection cylinder 1 can be quickly determined, thereby improving the efficiency of use.

[0024] By adopting the above technical solution:

[0025] Move the calibration component 3 on the outer wall of the sliding rod 22 upward so that the calibration component 3 and the lower surface of the limit cover 23 are in contact with each other, so that the lower surface of the calibration ruler 33 inside the calibration component 3 is flush with the upper surface of the detection cylinder 1, so that the height of the detection cylinder 1 can be quickly determined, thereby improving the efficiency of use.

[0026] Embodiment 2:

[0027] This embodiment provides a specific structure of a concrete slump detection device, such as Figure 1-4 As shown, the support assembly 2 includes a base 21, and the base 21 and the sliding rod 22 are detachably installed for replacing sliding rods 22 of different sizes. The sliding rod 22 and the limit cover 23 are detachably installed, and the cross-sectional diameter of the sliding rod 22 is smaller than the cross-sectional diameter of the limit cover 23. The top of the base 21 is provided with a sliding rod 22, and the top of the sliding rod 22 is provided with a limit cover 23. The support assembly 2 is placed on the side of the detection cylinder 1, and then the calibration assembly 3 is pulled up so that the upper surface of the calibration assembly 3 and the lower surface of the limit cover 23 inside the support assembly 2 are in contact with each other, so that the calibration ruler 33 inside the calibration assembly 3 is flush with the top of the detection cylinder 1, and then the limit piece 31 is tightened, and then the support assembly 2 is rotated to separate the calibration ruler 33 and the detection cylinder 1, and then the detection cylinder 1 is removed and the calibration ruler 33 is moved to the top of the concrete.

[0028] By adopting the above technical solution:

[0029] Place the support assembly 2 on the side of the detection cylinder 1, and then pull up the calibration assembly 3 so that the upper surface of the calibration assembly 3 contacts the lower surface of the internal limit cover 23 of the support assembly 2, so that the calibration ruler 33 inside the calibration assembly 3 is flush with the top of the detection cylinder 1, then tighten the limiter 31, and then rotate the support assembly 2 to separate the calibration ruler 33 and the detection cylinder 1, then remove the detection cylinder 1, and move the calibration ruler 33 to the top of the concrete.

[0030] Embodiment 3:

[0031] This embodiment provides a specific structure of a concrete slump detection device, such as Figure 1-4 As shown, the calibration component 3 includes a sliding ring 32 slidably connected to the sliding rod 22. The cross-sectional diameter of the inner circle of the sliding ring 32 is the same as the cross-sectional diameter of the sliding rod 22. The sliding ring 32 and the limiting member 31 are rotatable structures for limiting the sliding ring 32. A calibration ruler 33 is provided at one end of the sliding ring 32, and a limiting member 31 is provided at the other end of the sliding ring 32. Loosening the limiting member 31 allows the sliding ring 32 to rise and fall on the outer wall of the sliding rod 22. Thereafter, tightening the limiting member 31 allows the sliding ring 32 to contact the sliding rod 22, thereby allowing the calibration component 3 to be tightly connected to the support component 2.

[0032] By adopting the above technical solution:

[0033] Loosen the limiter 31 to allow the sliding ring 32 to rise and fall on the outer wall of the sliding rod 22, and then tighten the limiter 31 to allow the sliding ring 32 and the sliding rod 22 to contact each other, so that the calibration component 3 and the support component 2 can be tightly connected.

[0034] Working principle: When in use, place the detection cylinder 1 on a horizontal plane, then take out the concrete to be tested, and introduce the concrete into the detection cylinder 1. When introducing a part of the concrete, use a vibrating rod to vibrate the concrete inside the detection cylinder 1, and then continue to introduce the concrete into the detection cylinder 1, and then continue to vibrate until the concrete and the top of the detection cylinder 1 are flush with each other, then take out the support assembly 2, place the support assembly 2 on the side of the detection cylinder 1, and then pull up the calibration assembly 3 so that the upper surface of the calibration assembly 3 and the lower surface of the limit cover 23 inside the support assembly 2 are in contact with each other, so that the calibration ruler 33 inside the calibration assembly 3 is flush with the top of the detection cylinder 1, and then tighten the limiter 31, and then rotate the support assembly 2 to separate the calibration ruler 33 and the detection cylinder 1, and then remove the detection cylinder 1 and move the calibration ruler 33 to the top of the concrete.

[0035] After standing for a while, loosen the limiter 31, so that the sliding ring 32 and the sliding rod 22 slide against each other, so that the calibration ruler 33 at one end moves down to the upper surface of the concrete, and the data of the surface wall of the sliding rod 22 is taken out, which is the slump of the concrete.

[0036] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
