Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, and particularly relates to a concrete detection device for construction engineering. Background Technique

[0002] During the concrete detection process, it is necessary to detect its slump. The slump is a method and index for measuring the workability of concrete. Usually, a slump test is carried out to measure the fluidity of the mixture, and the cohesiveness and water retention are evaluated by visual experience. The slump is measured by a quantitative index, and its degree is used to judge whether the construction can proceed normally. When detecting the concrete slump, it is necessary to fill the slump cone with concrete, and then pull out the slump cone. The concrete collapses due to its own weight. Then, a straight rod is placed on the top of the slump cone, and a ruler is used to measure the distance from the straight rod to the highest point of the concrete. The difference generated is the slump of the concrete.

[0003] During the detection process of the current detection device, when pulling out the slump cone, it is all carried out manually. When manually pulling out the slump cone, it is easy to appear skewed, and then the concrete pile inside the slump cone is prone to deform and tilt under the action of external force, resulting in deviation of the concrete slump detection result.

[0028] A lifting screw rod 7 is rotatably connected to the inner side of a chute 3. A horizontal connecting beam 4 slides along the chute 3, and the horizontal connecting beam 4 is threadedly connected to the lifting screw rod 7. The horizontal connecting beam 4 is slidably connected through the limiting guide rod 8, which is convenient for driving the horizontal connecting beam 4 to perform stable vertical lifting and sliding. The slump cone 6 is detachably connected to the horizontal connecting beam 4 through a connecting rod 5, which is convenient for the slump cone 6 to be conveniently connected and also facilitates driving the slump cone 6 to perform accurate vertical lifting activities. A limiting guide rod 8 is installed on the inner side of the other chute 3. The top of the lifting screw rod 7 is connected to a driving motor 9. The top of the support frame 1 is fixedly installed with a top support beam 10, and the driving motor 9 is fixedly installed on the top support beam 10. A laser rangefinder 11 is embedded in the middle of the inner side of the top support beam 10;

[0029] The bottom end of the slump cone 6 is fixedly connected with a rubber base 12, and the top end of the slump cone 6 is fixedly connected with a connecting ring seat 13. A limiting card slot 14 is opened in the inner side of the connecting ring seat 13, and a clamping base 16 is embedded and clamped in the inner side of the limiting card slot 14. An aggregate shielding cover 15 is arranged at the edge end of the clamping base 16. The aggregate shielding cover 15 is tightly fitted and clamped with the limiting card slot 14 inside the connecting ring seat 13 through the clamping base 16 at its bottom end, which is convenient for quickly limiting and clamping the aggregate shielding cover 15 to the top of the slump cone 6, making it more convenient to add concrete into the slump cone 6 and avoiding the phenomenon of concrete spilling when adding concrete due to the small inlet of the slump cone 6.

[0030] A rotating motor 17 is installed on the top of the top support beam 10 on the side of the driving motor 9.

A bearing seat 18 is installed inside the top support beam 10 corresponding to the rotating sleeve 20, and the rotating sleeve 20 is rotatably connected in the bearing seat 18;

[0031] The bottom of the rotating sleeve 20 is telescopically connected with a telescopic rod 21, and the telescopic rod 21 is limited and clamped with the rotating sleeve 20 through a spring pin 22.

[0032] Working principle and usage process of the utility model: First, lower the slump cone 6 so that the rubber base 12 at its bottom contacts the ground. When the slump cone 6 contacts the ground, the deformation of the rubber base 12 is used to effectively seal the gap between them, avoiding the phenomenon of concrete leakage caused by uneven ground. At the same time, through the connecting ring seat 13, the limit card slot 14, and the clamping base 16, the aggregate baffle 15 is quickly and limit-clamped to the top of the slump cone 6, making it more convenient to add concrete into the slump cone 6, avoiding the phenomenon of spilling when adding concrete due to the small entrance of the slump cone 6, improving the convenience of operation. At the same time, the aggregate baffle 15 is convenient to disassemble and easy to clean later;

[0033] Next, inject the concrete to be tested into the slump cone 6 through the aggregate baffle 15. When injecting the concrete, it is convenient to drive the rotating sleeve 20 and the telescopic rod 21 to rotate by rotating the motor 17 and the bearing seat 18. The telescopic rod 21 drives the rotating swing rod 23 and the knocking rubber seat 26 to rotate. Through the reciprocating knocking and vibrating action of the knocking rubber seat 26 on the slump cone 6, the concrete in the slump cone 6 can be poured more tightly, avoiding the phenomenon of concrete accumulation not being compact;

[0034] The rotating sleeve 20 and the telescopic rod 21 can slide telescopically, which is convenient to adjust the position of the knocking rubber seat 26. The bearing seat 18 and the pin hole 19 are used to limit the telescopic rod 21, so as to ensure the stability of the knocking position of the knocking rubber seat 26, realize the adjustment of any vibration knocking position of the slump cone 6, and the knocking rubber seat 26 is elastically connected to the rotating swing rod 23 through the support spring 24 and the connecting rod 25, so that the knocking rubber seat 26 can closely adhere to the side of the slump cone 6, improving the actual knocking and vibrating effect;

[0035] After the concrete in the slump cone 6 is knocked and filled and full, it is convenient to drive the horizontal connecting beam 4 to perform stable vertical lifting and sliding through the support frame 1, the chute 3, the lifting screw rod 7, the limit guide rod 8, and the driving motor 9. The slump cone 6 is detachably connected to the horizontal connecting beam 4 through the connecting rod 5. While facilitating the convenient connection of the slump cone 6, it is also convenient to drive the slump cone 6 to perform precise vertical lifting activities, avoiding the phenomenon of the concrete pile being tilted due to external force when it is separated from the concrete, ensuring that the formed concrete pile does not deform. At this time, the height is detected by the laser rangefinder 11 in the middle of the top support beam 10, further improving the detection accuracy of the concrete slump and solving the problems of easy error and low detection accuracy in traditional ruler detection.
