Description

Technical Field

[0001] The utility model belongs to the technical field of water reducer performance testing, and more specifically, particularly relates to a device for testing the performance of anti-collapse water reducer. Background Art

[0002] In modern construction projects, concrete is one of the most important building materials, and its quality directly affects the safety and durability of building structures. However, in order to improve the anti-collapse performance of concrete, water reducers need to be added. It can reduce the water consumption while maintaining the workability of concrete and improve the performance of concrete such as strength. However, different types and qualities of water reducers have a great difference in the impact on the anti-collapse performance of concrete. Usually, water reducers are prone to failure in high-temperature weather, resulting in a fast slump loss of concrete. Therefore, it is necessary to test the performance of water reducers.

[0003] Based on the above, however, when the current testing device tests the water reducer, it needs to be mixed with concrete for testing. Then, it is found during the testing that the placement tray for placing concrete is likely to leave concrete, which is likely to cause the dried concrete to affect the subsequent test results. Moreover, during the current testing, the staff needs to stir the materials, which is not only time-consuming and laborious, but also prone to the problem of uneven mixing.

[0036] Embodiment 1: As shown in Figure 1 to Figure 6 shown:

[0037] The present utility model provides a performance testing device for anti-collapse water reducing agent, including a heating box 1 and a disassembly structure 3;

[0038] The interior of the heating box 1 is provided with an inner cavity 101. The front end of the heating box 1 is hinged with a box door 102. An observation window 1021 is provided on the box door 102. A fixed support 301 is fixedly connected in the inner cavity 101. At both ends of the top of the fixed support 301, connecting lugs 3011 are fixedly connected. A sliding support hole 3012 is formed inside the connecting lug 3011. A reset groove 3013 is formed inside the connecting lug 3011 on the outside of the sliding support hole 3012. A spring 3014 is provided inside the reset groove 3013. A connecting convex column 302 is provided inside the reset groove 3013. A sliding support column 3021 is fixedly connected to the midpoint of the connecting convex column 302. The sliding support column 3021 extends to the outside and is fixedly connected to a pull plate 3022. Locking insertion columns 3023 are fixedly connected to both ends of the pull plate 3022. A collection box 303 is provided on the top of the fixed support 301. Fixed lugs 3031 are fixedly connected to both sides of both ends of the collection box 303. A locking insertion hole 3032 is formed on the fixed lug 3031. The locking insertion column 3023 is inserted inside the locking insertion hole 3032. Limiting vertical plates 3033 are fixedly connected to both ends of the top of the collection box 303. A collapse cylinder 304 is provided on the top of the collection box 303. Connecting support plates 3041 are fixedly connected to both sides of the collapse cylinder 304. A limiting slot 3042 is formed on the connecting support plate 3041. The limiting slot 3042 is sleeved on the outside of the limiting vertical plate 3033. The function of the heating box 1 is to simulate the high temperature outdoors. By pulling the pull plate 3022 to drive the locking insertion column 3023 to disengage from the locking insertion hole 3032, the collection box 303 can then be taken out of the inner cavity 101 and then cleaned. After cleaning, the collection box 303 is installed on the top of the fixed support 301, and then the pull plate 3022 is released. Because when the pull plate 3022 moves, it drives the connecting convex column 302 to squeeze the spring 3014 in the reset groove 3013 through the sliding support column 3021, causing the spring 3014 to generate elasticity. When the pressure is lost, at this time, the spring 3014 generates a reaction force, thereby pushing the connecting convex column 302 to move. The connecting convex column 302 drives the pull plate 3022 to reset through the sliding support column 3021. The pull plate 3022 drives the locking insertion column 3023 to be inserted into the locking insertion hole 3032, thereby completing the limitation of the collection box 303.

A stirring blade 2037 is fixedly connected to the outer side of the bottom of the stirring rod 2035. By starting the motor 2031 to drive the first gear 2032 to rotate, the first gear 2032 meshes with the three second gears 2036 to rotate. The second gear 2036 drives the stirring rod 2035 to rotate. The stirring rod 2035 drives the stirring blade 2037 to stir the materials in the mixing barrel 201 to ensure that the materials are stirred evenly.

[0040] Specific usage method and function of this embodiment:

[0041] In the present utility model, first, the proportioned materials are put into the mixing barrel 201 through the feed hopper 2011. Then, the motor 2031 is started to drive the first gear 2032 to rotate. The first gear 2032 meshes with the three second gears 2036 to rotate. The second gear 2036 drives the stirring rod 2035 to rotate. The stirring rod 2035 drives the stirring blade 2037 to stir the materials in the mixing barrel 201 to ensure that the materials are stirred evenly. Then, the corrugated discharge pipe 2012 is pulled open so that the bottom end extends into the slump cone 304. Then, the solenoid valve 202 is opened, so that the mixed concrete enters the slump cone 304. Then, the inside of the slump cone 304 is tapped to compact the internal concrete to avoid voids. Then, it is heated by the heating box 1 to simulate the external high-temperature weather. Then, the slump values before and after placement are measured to evaluate the slump retention ability of the water reducer. After the test is completed, by pulling the pull plate 3022 to drive the locking plug post 3023 to disengage from the locking jack 3032, the collection box 303 can be taken out of the inner cavity 101, and then it is cleaned to avoid affecting the subsequent test structure and ensure the reliability of the test results.
