Description

Technical Field

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

[0002] Slump is a method and index for measuring the workability of concrete. In construction sites and laboratories, generally, the slump test is carried out to measure the fluidity of the mixture, and the cohesiveness and water retention are evaluated by intuitive experience. Slump is measured by a quantitative index to judge whether the construction can proceed normally.

[0003] After retrieval, a patent with the application number CN202311657536.6 discloses a concrete slump detection device, which includes a steel bottom plate. A loading component is arranged at the top of the steel bottom plate, and the loading component is used to load the concrete for detection. A stirring device is arranged on one side of the top of the steel bottom plate. The stirring device is used to insert and stir the concrete inside the loading component, and an airbag is installed. Through the setting of the airbag, before the conical cylinder is separated from the concrete, the conical cylinder can be slightly separated from the concrete, avoiding the conical cylinder touching the concrete when it is lifted or removed, resulting in the inclined state of the concrete.

[0004] However, the existing slump test methods are similar to the principle methods of the above-cited patent. Concrete is poured into a trumpet-shaped slump bucket with a narrow top and a wide bottom, tamped, leveled, and then the bucket is pulled out. The concrete slumps due to its own weight. However, when removing the slump bucket in this way, due to the large adhesion force between the concrete and the inner wall of the bucket, it is easy to apply uneven force when manually removing the bucket, which will drive the concrete to move, so an external inclined force is applied to the concrete, which easily causes the concrete to slump and reduces the detection effect.

[0005] Therefore, a concrete slump detection device is proposed to solve the defects still existing in the above situation. Content of the Utility Model

[0027] The working principle of the present utility model:

[0028] In the present utility model, when the device is taken and separated, the motor 8 is started through the switch group 601 on the outer side of the movable block 6. The motor 8 drives the small gear disk 802 at the power end to rotate and engage with the large gear disk 803 on the outer side of the threaded rod 602, thereby driving the threaded rod 602 to rotate slowly and driving the movable block 6 to slide up and down along the fixed rod 5 by threading, and then driving the mounting frame 4 and the connected slump cone 3 to slowly rise and fall by means of the movable block 6, avoiding the slump of the concrete in contact pieces during taking and reducing the detection effect; the staff can start the motor during the process of pouring concrete.

At this time, the turntable 1003 drives the movable rod 1002 to move leftward and drives the knocking plate 11 to knock on the outer wall of the slump cone 3. During the movement of the movable rod 1002, the limiting rod 1005 on the outer side slides along the slide rail 1006 and compresses the spring 1007. When the teeth on the outer side of the turntable 1003 are disengaged from the tooth grooves 1004 at the upper end of the movable rod 1002, at this time, the spring 1007 elastically recovers and drives the movable rod 1002 and the connected knocking plate 11 to move back to the right. Finally, with the rotation of the motor, the movable rod 1002 and the knocking plate 11 reciprocally knock on the surface of the slump cone 3 to vibrate it, facilitating the full accumulation of the concrete during filling and realizing the uniform filling of the concrete into the slump cone 3, which is convenient for subsequent detection and use.
