Description

Technical Field

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

[0002] Concrete slump test is generally used to test the cohesiveness and water retention of concrete. Slump is a quantitative indicator used to measure its degree and is used to determine whether the construction can proceed normally.

[0003] At present, in the prior art, concrete is filled into a conical cylinder in three times, and the concrete is compacted by tamping, and then the conical cylinder is manually lifted upward to separate it from the concrete, and then the slump of the concrete is detected. However, in the process of manually lifting the conical cylinder, the conical cylinder is prone to tilt, causing the concrete to be in a tilted state. After the concrete is in a tilted state, its slump will be inaccurate, and the slump needs to be re-detected. In order to solve the above problem, announcement number CN221465534U discloses a concrete slump detection device, which utilizes a driving component to enable the slump cylinder to slide vertically with the help of the driving component after the concrete is filled into the slump cylinder, so that the slump cylinder can be smoothly separated from the filled concrete, thereby ensuring the verticality of the concrete and avoiding as much as possible the verticality of the concrete being affected by the shaking of the slump cylinder when the slump cylinder is separated from the filled concrete, thereby causing deviations in the detection results.

[0004] However, during the actual use of the device, due to the start-up of the motor, the device as a whole will produce a certain amplitude of vibration. As a result, in the process of the slump cone gradually rising, the concrete may collapse due to the shaking, thereby causing deviations in the detection results. In view of this, the present invention proposes a concrete slump detection device. Summary of the invention

The splitting process is stable to prevent shaking, thereby improving the accuracy of the detection result. At the same time, during the gradual separation of the collapse half-drum one and the collapse half-drum two, the collapse half-drum one and the collapse half-drum two can be separated from the bottom plate, thereby reducing the wear of the collapse half-drum one and the collapse half-drum two and extending the service life of the collapse half-drum one and the collapse half-drum two.

A connecting rod 58 is fixedly connected to the outer wall of the block 54. By starting the cylinder 1 51, the output end of the cylinder 1 51 drives the mounting block 52 to move, thereby driving the block 54 and the connecting rod 58 to move, and under the action of the guide member 55, the round rod 57 slides in the guide groove 56, so that the connecting rod 58 moves stably. And the telescopic end of the elastic telescopic rod 1 53 is telescoped, so that the collapsed half cylinder 1 21 and the collapsed half cylinder 22 can be merged and split, and the splitting process is stable to prevent shaking, thereby improving the accuracy of the detection result. At the same time, in the process of gradual separation of the collapsed half cylinder 1 21 and the collapsed half cylinder 22, the collapsed half cylinder 1 21 and the collapsed half cylinder 22 can be separated from the bottom plate 1, reducing the wear of the collapsed half cylinder 1 21 and the collapsed half cylinder 22, and extending the service life of the collapsed half cylinder 1 21 and the collapsed half cylinder 22.
