Description

Technical Field

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

[0002] Slump is mainly used to reflect the workability of concrete, which mainly includes the water retention, fluidity and cohesion of concrete. The slump cone is an important tool for testing the slump of concrete mixture properties. It has a simple structure and is widely used in teaching and practical testing. During the slump test, concrete needs to be poured into the trumpet-shaped slump cone three times. After each filling, the concrete mixture needs to be tamped with a tamping rod. After the slump cone is filled with the concrete mixture, the slump cone is lifted vertically upward to separate the concrete mixture from the slump cone. The concrete mixture will collapse due to its own weight, and the height of the concrete mixture collapsing downward is the slump.

[0003] After the experiment is completed, the inside of the slump cone needs to be cleaned, but the existing concrete slump detection device does not have a linkage cleaning function, which causes the concrete uniformity in the barrel to be inconsistent with the actual situation, which may easily cause the next concrete slump detection to be inaccurate. If you put your arm into the slump cone for manual cleaning, on the one hand, the cleaning is not convenient enough; on the other hand, it is easy to miss some places to be cleaned, resulting in the inside of the slump cone not being cleaned properly, which will affect the test results when used next time. Therefore, we provide a concrete slump detection device. Utility Model Content

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific implementations and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0026] See also Figure 1-Figure 3 The utility model provides a concrete slump detection device, comprising:

[0027] Bottom plate 1;

[0028] A fixing frame 2, wherein the fixing frame 2 is arranged on the bottom plate 1;

[0029] A lifting mechanism 4, wherein the lifting mechanism 4 is disposed between the bottom plate 1 and the fixed frame 2, and the lifting mechanism 4 is used to drive the slump cone 7 to move up and down;

[0030] A cleaning mechanism 3, wherein the cleaning mechanism 3 is disposed on the top wall of the fixed frame 2, and the cleaning mechanism 3 comprises a motor 31, wherein the motor 31 is used to drive a brush plate 34 to rotate, and the brush plate 34 is adapted to the inner wall of the slump cone 7;

[0031] The overturning mechanism 6 is used to overturn the slump cone 7.

[0032] The lifting mechanism 4 includes a threaded rod 42 rotatably connected to the fixed frame 2 and the base plate 1 and a sliding rod 44 fixedly connected to the fixed frame 2 and the base plate 1. The two ends of the slump cone 7 are respectively connected to a sliding block 43 threadedly connected to the threaded rod 42 and a sliding block 43 slidably matched with the sliding rod 44.

[0033] Specifically, the top end of the threaded rod 42 passes through the fixed frame 2 and is fixedly connected to the turntable 41. A handle is provided at the edge of the turntable 41. The threaded rod 42 can be conveniently rotated by holding the handle to drive the slider 43 to move up and down, thereby driving the slump cone 7 to move up and down; when the bottom wall of the slump cone 7 contacts the bottom plate 1, it is convenient to pour concrete into the slump cone 7; then the slump cone 7 is driven to move upward, which is convenient for the slump cone 7 to be separated from the concrete inside, so that the concrete collapses completely.

[0034] The measuring mechanism 5 comprises a fixed rod 51 and a scale 55 mounted on the bottom plate 1. The fixed rod 51 is slidably fitted with a movable sleeve 52. A horizontally arranged positioning rod 54 is mounted on the outer surface of the movable sleeve 52. A fastening bolt 53 is threadedly connected to the side wall of the movable sleeve 52. The fastening bolt 53 penetrates the side wall of the movable sleeve 52 and abuts against the fixed rod 51. When the concrete collapses completely, the restriction of the movable sleeve 52 by the fastening bolt 53 is released, so that the positioning rod 54 can be moved up and down and rotated conveniently, so that the positioning rod 64 contacts the top of the collapsed concrete and the scale 55 in turn, and then the height of the collapsed concrete is measured.

[0035] It should be noted that matching indicator needles may be provided on the fixed rod 51 and the movable sleeve 52 , so as to facilitate moving the movable sleeve 52 to the initial position, and further facilitate fastening the bolts 53 to re-fix the movable sleeve 52 on the fixed rod 51 .

[0036] Specifically, the motor 31 is arranged on the top wall of the fixed frame 2, and the output end of the motor 31 is fixedly connected to the first rotating shaft 32. Connecting rods 33 are arranged at intervals on the outer surface of the first rotating shaft 32. The end of the connecting rod 33 is fixedly connected to a brush plate 34. The distance between the brush plate 34 and the central axis of the first rotating shaft 32 gradually decreases from top to bottom, which is adapted to the inner wall of the conical slump cone 7.

[0037] It should be noted that although the structure of the brush board 43 is adapted to the inner wall of the conical slump cone 7, when the bottom wall of the slump cone 7 contacts the bottom plate 1, the width of the bottom end of the slump cone 7 is greater than the width of the top end, so that the brush board 43 cannot enter the interior of the slump cone 7; and the distance between the brush board 34 and the central axis of the first rotating shaft 32 is set to gradually increase from top to bottom; the brush board 43 is also unable to enter the interior of the slump cone 7; therefore, in this embodiment, a flip mechanism 6 is provided to drive the slump cone 7 to rotate 180°, so that the brush board 43 can smoothly enter the interior of the slump cone 7.

[0038] Specifically, the flip mechanism 6 includes a second rotating shaft 61 fixedly connected to the outer wall of the slump cone 7, and one end of the second rotating shaft 61 away from the slump cone 7 is rotatably connected to the slider 43. A fixing sleeve 63 is fixedly connected to the second rotating shaft 61, and a screw rod 64 is threadedly connected to the fixing sleeve 63, and an adjusting knob is arranged at the end of the screw rod 64; a semi-circular arc groove 431 is provided on the slider 43, and a limiting hole 432 is provided at the end of the semi-circular arc groove 431, and the bottom end of the screw rod 64 is adapted to the semi-circular arc groove 431 and the limiting hole 432. By rotating the adjusting knob, the end of the screw rod 64 can be conveniently driven to enter the semi-circular groove 431 and the limiting hole 432. When the end of the screw rod 64 enters the semi-circular groove 431, the limitation of the semi-circular groove 431 can ensure that the second rotating shaft 61 rotates 180°, thereby causing the slump cone 7 to flip over. After the slump cone 7 flips over, the end of the screw rod 64 is driven to enter the limiting hole 432. The limiting hole 432 cooperates with the screw rod 64 to limit the slump cone 7 from continuing to rotate, thereby keeping the slump cone 7 in a stable state.

[0039] Optionally, a hand-held rod 62 is fixedly connected to the second rotating shaft 61, and a handle is also provided at the end of the hand-held rod 62. By providing the hand-held rod 62, it is easier to rotate the second rotating shaft 61.
