Description

Technical Field

[0001] The invention relates to the field of concrete slump test, and more specifically to a concrete collapse test system for construction engineering. Background Art

[0002] The concrete slump test is a test method for the fluidity of concrete. The concrete is loaded into a conical slump cone of a specified height, the cone is lifted vertically, and the height of the concrete after collapse is measured to determine the fluidity of the concrete.

[0003] When concrete falls into a slump cone, it is easy to create gaps with the inner wall of the slump cone, which requires manual compaction of the concrete in the slump cone. However, due to the obstruction of aggregates in the concrete, manual compaction often results in missing gaps, resulting in inaccurate results of subsequent slump tests. In addition, residual concrete is easily attached to the inner wall of the slump cone after use. Manual cleaning of the inner wall of the slump cone requires going deep into the center of the slump cone. This method of removing residual concrete is more troublesome. Summary of the invention

The upper ends of the sixteen push rods 4 are fixedly connected to handles 5. The trigger device 2 includes a U-shaped frame 201, and a rotating rod 202 is rotatably connected to the lower end of the U-shaped frame 201. Two gears 203 are fixedly connected to the outer end of the rotating rod 202. Connecting rods 204 are fixedly connected to both ends of the middle of the rotating rod 202, and a first magnet 205 is fixedly connected to the end of the connecting rod 204 away from the rotating rod 202.

[0037] See also Figures 3-9 The linkage device 3 includes a housing 301, protrusions 302 are fixedly connected at both ends of the housing 301, arc plates 303 are fixedly connected at the middle of both ends of the housing 301, an air bag 304 is fixedly connected to the side of the arc plate 303 close to the inner wall of the slump cone 101, a scraper 305 is fixedly connected to the side of the air bag 304 close to the inner wall of the slump cone 101, and a second magnet 306 is slidably connected inside the housing 301, so that the concrete gaps can be removed by vibration, and the residual concrete attached to the inner wall of the slump cone 101 can be scraped off. The upper end of the U-shaped frame 201 is fixedly connected to the push rod 4, and the upper end of the housing 301 is fixedly connected to the push rod 4, so that the push rod 4 can drive the trigger device 2 and the linkage device 3 to move.

[0038] See also Figures 3-10 The linkage devices 3 are arranged in an up-and-down staggered manner in a clockwise direction with the center line of the collapse cone 101 as the center, and the linkage devices 3 correspond to the trigger devices 2 one by one, so that the multiple linkage devices 3 can completely scrape off the residual concrete attached to the inner wall of the collapse cone 101, and the trigger device 2 can drive the second magnet 306 inside the corresponding linkage device 3 to move. The rotating rod 202 matches the slide rail 104, and the gear 203 is meshed with the rack 103, so that the slide rail 202 can limit the rotating rod 202 to prevent the trigger device 2 from deviating, and the gear 203 can rotate by moving up and down.

[0039] See also Figures 2-10The two first magnets 205 have opposite magnetic poles at the ends away from each other, and the second magnet 306 is in the shape of a cube, so that the two first magnets 205 can attract and repel the second magnet 306 respectively, and the second magnet 306 is not easy to rotate. The shell 301 and the protrusion 302 match the chute 102, and the inner material of the scraper 305 is hard plastic, so that the linkage device 3 is not easy to escape from the middle of the chute 102, and the scraper 305 can be squeezed by the airbag 304 so as to be slightly deformed and fit the inner wall of the collapse cone 101.

[0040] During the experiment, concrete is first poured into the collapse cylinder 101, and the staff steps on the two pedals 105 and holds the handle 5, and drives the push rod 4 to move up and down through the handle 5, and the push rod 4 drives the trigger device 2 and the linkage device 3 to move up and down;

[0041] During the up-and-down movement of the trigger device 2, since the gear 203 is meshed with the rack 103, the gear 203 rotates during the up-and-down movement, and the gear 203 drives the connecting rod 204 and the first magnet 205 to rotate through the rotating rod 202. The two first magnets 205 approach the second magnet 306 in sequence. Since the magnetic poles of the two ends of the first magnets 205 that are far away are opposite, the second magnet 306 reciprocates inside the shell 301, and the second magnet 306 hits the inner wall of the shell 301 to make the shell 301 vibrate. While the shell 301 vibrates, it drives the arc plate 303 to vibrate. The shell 301 and the arc plate 303 vibrate the concrete at the inner wall of the collapse cone 101 to remove the gaps. The airbag 304 squeezes the scraper 305 to fit the inner wall of the collapse cone 101. During the up-and-down reciprocating movement of the linkage device 3, the scraper 305 scrapes the concrete gaps at the inner wall of the collapse cone 101.

[0042] When the concrete in the slump cone 101 is compacted, the worker holds the handle 5 and lifts the trigger device 2 and the linkage device 3 to the highest position in the slump cone 101 through the push rod 4. The worker leaves the pedal 105 with both feet and lifts the handle 5 vertically. The slump cone 101 rises vertically, and the concrete in the slump cone 101 escapes. The height of the concrete is measured and the fluidity of the concrete is analyzed.

[0043] After the experiment, the slump cone 101 is placed back on the ground, the handle 5 is pushed downward, the handle 5 pushes the linkage device 3 downward through the push rod 4, the scraper 305 moves downward, and the scraper 305 is pressed and fits the inner wall of the slump cone 101 under the action of the airbag 304. Multiple scrapers 305 simultaneously scrape down the concrete residue attached to the inner wall of the slump cone 101 to complete the slump test of the concrete. The trigger device 2 can be used to drive the linkage device 3 to vibrate, so that the concrete gap at the inner wall of the slump cone 101 is removed, thereby improving the accuracy of the slump test, and the linkage device 3 scrapes off the residual concrete on the inner wall of the slump cone 101 after use, thereby reducing the workload of cleaning the slump cone 101 after use.

[0044] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
