Description

Technical Field

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

[0002] The slump mainly refers to the plasticizing performance and pumpability of concrete. It is measured by a quantitative index to measure the level of its plasticizing and pumpability, and is used to judge whether the construction can proceed normally. The main factors affecting the slump of concrete include gradation change, water content, weighing deviation of the scale, dosage of admixture, and the temperature of cement which is easily overlooked. The slump refers to the workability of concrete. Specifically, it ensures the normal progress of construction, including the water retention, fluidity and cohesion of concrete. The test method of slump: use a slump bucket with a 100mm upper opening, 200mm lower opening and 300mm height. After filling it with concrete and tamping it, then pull out the bucket. The concrete collapses due to its own weight. Subtract the height of the highest point of the collapsed concrete from the bucket height (300mm), which is called the slump. If the difference is 10mm, the slump is 10...

[0003] Before the existing slump test, a small amount of cement needs to be filled into the slump bucket, and then the cement in the slump bucket is tamped 24 times with a manual tamper. Repeat the above process, so that the slump of the cement can be quickly detected. However, this manual tampering method is not only time-consuming and laborious, but also prone to cement collapse due to inclination during manual tampering, thus seriously affecting the detection accuracy of the cement slump.

[0034] In the embodiment of the present application, as Figures 1-4 shown, the ramming mechanism includes a limiting frame 4 installed on the top of the bottom plate 1, a fixing plate 6 is installed on the top of the limiting frame 4, a driving box 7 is fixedly connected to the top of the fixing plate 6, a first motor 8 is fixedly connected to the outer surface of one side of the driving box 7, a rotating shaft 9 is fixedly connected to the output end of the first motor 8, the other end of the rotating shaft 9 extends into the inside of the driving box 7 and is fixedly connected with a semi-gear disc 10, a driven gear 11 is meshed with one side of the semi-gear disc 10, a driven shaft 12 is fixedly connected to the inside of the driven gear 11, the other end of the driven shaft 12 extends to the other side of the driving box 7 and is hinged with a first connecting rod 13, one end of the first connecting rod 13 far away from the driven shaft 12 is hinged with a second connecting rod 14, the other end of the second connecting rod 14 is hinged with a ramming rod plate 5, and the bottom of the ramming rod plate 5 extends through and below the limiting frame 4.

[0035] By adopting the above technical solution, the device can automatically drive the ramming rod plate 5 to ram the inside of the slump cone 3 through the ramming mechanism, so that the inside of the cement is densely combined, and phenomena such as honeycombing and pitting on the concrete can be eliminated, thereby greatly improving the detection accuracy of the device.

[0036] In the embodiment of the present application, as Figure 1 shown, a limiting groove is penetrated through the inside of the limiting frame 4, and the ramming rod plate 5 is slidably connected with the limiting groove.

[0037] By adopting the above technical solution, with the limiting effect of the limiting groove, the ramming rod plate 5 can perform a better linear lifting motion.
