Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete mixture detection, in particular to a portable concrete slump detection device. Background Art
[0002] The concrete slump is an important index to measure the fluidity and workability of concrete, specifically referring to the degree to which concrete can flow under its own weight. It is measured through a standard test: fill a conical container (usually called a slump cone) with a large upper diameter, a small lower diameter, and a fixed height with a concrete sample. After filling and tamping, suddenly lift the container and let the concrete slump freely. Measure the vertical distance from the lowest point at the top of the concrete to the bottom edge of the slump cone at this time, which is the slump value. The larger this value is, the thinner the concrete is and the better its fluidity; conversely, the smaller the value is, the thicker the concrete is and the poorer its fluidity.
[0003] Patent CN220419339U discloses a portable concrete slump detection device. By setting a tamping mechanism, the lifting plate can be moved up or down by driving the lead screw to rotate clockwise or counterclockwise by a servo motor, so that the tamping rod can be inserted into the concrete mixture, and the driving motor is cooperated to drive the tamping rod to rotate, thereby tamping the concrete, eliminating the need for manual tamping, saving time and effort; when detecting the concrete slump, the scale is rotated to make the benchmark located at the top of the concrete, and the slump value can be detected by detecting the height difference between the height of the slump cone and the highest point of the concrete after slumping. However, such a measurement cannot directly show what the slump value of the concrete is. It is necessary to detect the slump value of the concrete by detecting the height difference between the height of the slump cone and the highest point of the concrete after slumping. Such a calculation not only requires secondary calculation but also easily leads to deviation of the obtained numerical value.
[0004] Therefore, the utility model provides a portable concrete slump detection device to solve the above problems. Content of the Utility Model

[0035] Embodiment 1
[0036] This embodiment provides a portable concrete slump detection device, as Figures 1 to 3As shown in the figure, it includes a mobile base 1, a slump cone 2 placed above the mobile base 1 for containing concrete, and a measuring component 4 for detecting the slump of concrete; the slump cone 2 is vertically through, used to contain concrete before testing, and the slump cone 2 is vertically removed during testing to achieve the slump of concrete; the measuring component 4 includes a bracket 41, a sleeve 42 and a scale plate 43; the bracket 41 is arranged on the upper surface of the mobile base 1, and a through hole allowing the sleeve 42 to penetrate is arranged at the top of the bracket 41; the sleeve 42 is movably connected to the bracket 41, a through groove is arranged along the length direction of the sleeve 42 and the bottom is open, the scale plate 43 is arranged in the through groove and is allowed to move up and down along the through groove, and scale bars are arranged from bottom to top along the length direction of the scale plate 43; a first positioning plate 421 is arranged on one side of the bottom of the sleeve 42 close to the slump cone 2; a second positioning plate 431 is arranged on one side of the bottom of the scale plate 43 close to the slump cone 2.
[0037] Further, a guide rail 46 is arranged on the upper surface of the mobile base 1, and the bottom end of the bracket 41 is movably connected to the guide rail 46; the guide rail 46 allows the bracket 41 to approach or move away from the slump cone 2 (to realize the position movement of the measuring component 4).
[0038] Further, an extension plate 432 is sleeved outside the second positioning plate 431, and the extension plate 432 is movably connected to the second positioning plate 431 through a first bolt 433; a guide hole allowing the first bolt 433 to be threadedly connected to the extension plate 432 is arranged on the extension plate 432; the first bolt 433 is used to realize the movement and fixation of the extension plate 432 relative to the second positioning plate 431; a traction spring 422 is arranged in the sleeve 42, and the traction spring 422 allows the scale plate 43 to be reset; one end of the traction spring 422 is connected to the top wall of the cavity, and the other end is connected to the bottom of the scale plate 43; in the initial state, the contraction force of the traction spring 422 is greater than the sum of the gravity of the scale plate 43, the second positioning plate 431, the extension plate 432 and the first bolt 433.
[0039] Further, a second bolt 44 is threadedly inserted at the position of the through hole of the bracket 41, and the second bolt 44 is used to realize the movement and fixation of the sleeve 42 relative to the bracket 41, so as to ensure that the measuring component 4 can be applied to slump cones 2 of different heights and improve the applicability of the device.
[0040] Further, an auxiliary plate 45 is arranged on one side of the top end of the slump cone 2 close to the bracket 41, and the upper surface of the auxiliary plate 45 is on the same horizontal plane as the upper surface of the slump cone 2; the auxiliary plate 45 is used to facilitate the position positioning of the first positioning plate 421.
[0041] Furthermore, the slump cone 2 is frustum-shaped, with its top aperture smaller than the bottom aperture; a flared pipe 3 in the shape of a frustum is provided at the top of the slump cone 2. The aperture at the top of the flared pipe 3 is larger than that at the bottom. The bottom of the flared pipe 3 is allowed to extend into the slump cone 2 through the top and is fitted with the slump cone 2. Among them, the setting of the flared pipe 3 facilitates the pouring of concrete into the slump cone 2.
[0042] Furthermore, a handrail 5 for facilitating the operator to control the movement of the moving base 1 is also provided at the end of the upper surface of the moving base 1.
[0043] During use, first, adjust the position of the first positioning plate 421 so that the bottom end of the first positioning plate 421 fits against the top end of the slump cone 2 (when necessary, move the position of the bracket 41 through the guide rail 46), that is, the bottom end of the first positioning plate 421 fits against the top end of the auxiliary plate 45. At this time, the initial value of the scale plate 43 is 0. Then, pour the concrete into the slump cone 2 through the flared bottle (until the upper surface of the concrete is flush with the upper surface of the slump cone 2). Then, vertically lift the slump cone 2 upward. The concrete inside the slump cone 2 slumps. At this time, adjust the scale plate 43 so that the bottom of the extension plate 432 contacts the highest point of the slumped concrete (at this time, the traction spring 422 is in a stretched state). At this time, the scale value at the contact between the scale plate 43 and the sleeve 42 is the slump value of the concrete. After the measurement is completed, the traction spring 422 drives the scale plate 43 to reset.
[0044] Among them, in the case where the concrete is thinner, there will be a problem that the greater the slump value of the concrete, the larger the slump range, so that the second positioning plate 431 cannot perform a specified measurement on the slump of the concrete. At this time, the extension plate 432 can be adjusted to move away from the scale plate 43. When adjusted to the required position, then use the first bolt 433 to fix the extension plate 432 relative to the second positioning plate 431, thereby realizing the measurement of the slump value of the concrete.

It is obvious that those skilled in the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative labor. Therefore, the present utility model is not limited to the above embodiments, and all improvements and modifications made by those skilled in the art without departing from the scope of the present utility model according to the interpretation of the present utility model should be within the protection scope of the present utility model.
