Description

TECHNICAL FIELD

[0001] The utility model relates to concrete rheometer technical field, specifically, relate to an improved concrete rheometer test barrel. BACKGROUND

[0002] Self-compacting concrete has good workability and passability, good compactness and good durability, and consumes a large amount of solid waste fly ash, meeting the requirements of green and low carbon, and having great advantages in engineering compared with ordinary concrete. The concrete rheometer characterizes the workability of the self-compacting concrete by testing the viscosity and yield stress of the self-compacting concrete, which can test whether the state of the self-compacting concrete is good, and provide a basis for the mix design of the self-compacting concrete based on the rheological theory. At the same time, the concrete rheometer can also test the rheological property of the freshly mixed concrete, and accurately determine the workability of the concrete mixture required for different pouring processes.

[0003] At present, the concrete rheometer test barrels on the market are mostly one-piece iron barrels with resistance strips, and the amount of concrete for one test is 20L to 25L. After the concrete is mixed, it is poured into the iron barrel for testing, the resistance ribs provide the frictional resistance of the concrete, and after the test is completed, the mixture is poured out along the barrel opening. Since the mass of the concrete in the barrel is heavy, it is difficult to pour out the mixture after the test, which can easily press the barrel opening into an oval shape and affect the test results next time, and the inner wall of the barrel is not easy to clean. At the same time, when the resistance ribs are damaged, it is difficult to replace them, and even the entire rheometer test barrel needs to be replaced, which is high in cost. UTILITY MODEL CONTENTS

[0004] The utility model aims at providing an improved concrete rheometer test barrel, which can realize rapid discharge of the mixture, facilitate replacement of the resistance ribs, and save cost.

[0005] The utility model realizes the following technical scheme:

[0006] An improved concrete rheometer test barrel, comprising a barrel body and a base, the barrel body and the base are detachably connected through a fixing structure, a plurality of installation rails are arranged on the inner wall of the barrel body, a resistance rib is slidably installed in each installation rail, a high-speed camera is installed on the top of the barrel body, and a picture sensor is connected to the high-speed camera.

[0007] Further, the fixing structure comprises a connecting groove arranged on the outer wall of the barrel body and a connecting buckle arranged on the outer wall of the base, and the connecting buckle is adaptively connected with the connecting groove.

[0008] Further, the connecting buckle is a stainless steel tower buckle.

[0009] Furthermore, the base has a cavity at its top, and the inner wall of the cavity is provided with a rubber ring.

[0010] Furthermore, the outer diameter of the cylinder is the same as the inner diameter of the cavity, and the lower end of the cylinder is inserted into the cavity.

[0011] Furthermore, a handle is welded to the outer wall of the cylinder.

[0012] Furthermore, the top outer wall of the cylinder is provided with an annular groove, and the high-speed camera is slidably installed in the groove.

[0013] Furthermore, a slider is connected to the high-speed camera, and a ball bearing is provided at the bottom of the slider, the ball bearing being adapted to the groove.

[0014] The technical solution of this utility model has at least the following advantages and beneficial effects:

[0015] In this invention, the base and cylinder are detachably connected to enable rapid dispensing of the mixture, preventing the cylinder opening from being compressed into an elliptical shape due to the high viscosity of the mixture making it difficult to pour. Resistance ribs are slidably installed within the mounting track, providing varying levels of resistance and facilitating rib replacement. This prevents excessive wear of the resistance ribs from necessitating the replacement of the entire test cylinder, thus saving costs. A high-speed camera and image sensor work together to capture the state of the mixture during shearing. Combining the images and data allows for better analysis of the mixture's state, facilitating observation of the concrete shearing process. Attached Figure Description

The resistance rib 4 is slidably installed in the installation rail 3, which can provide different resistance and facilitate replacement of the resistance rib 4, so that the resistance rib 4 does not need to be replaced due to excessive wear, and cost is saved. The high-speed camera 5 and the picture sensor cooperate to capture the state of the mixture during shearing, and the combination of the picture and the data can better analyze the state of the mixture, and the shearing process of the concrete can be observed.

[0030] In the specific embodiment of the present embodiment, the fixing structure 6 comprises a connecting groove 61 arranged on the outer wall of the barrel 1 and a connecting buckle 62 arranged on the outer wall of the base 2, and the connecting buckle 62 is adaptively connected with the connecting groove 64.
