Description

Technical Field

[0001] The utility model relates to the technical field of concrete strength detection, in particular to a strength detection device for concrete experiments. Background Art

[0002] Concrete is one of the most commonly used structural materials in civil engineering. Its strength directly affects the safety of buildings, bridges, roads, and other infrastructure. Strength testing can ensure that the structure can withstand the design load and pressure under extreme conditions within its expected service life, avoiding structural damage caused by insufficient strength, thereby protecting people's lives and property safety.

[0003] The existing experimental method is to pour multiple square concrete blocks and place them on the induction seat of the pressure testing machine. By applying pressure, the digital display on the control box shows the stress on the concrete, and then the concrete strength is calculated using a formula.

[0004] After searching, for example, the utility model patent with Chinese publication number CN219657365U discloses a concrete strength crushing test device. By providing a protective cover, the crushing test device has a good dust-proof effect, which is convenient for blocking concrete residues and improving the protection of operators. At the same time, a cleaning device is provided to automatically collect and clean the concrete residues after the test. However, the dust collecting pipe of the device is arranged next to the detection point, and the dust collecting pipe is not protected. During the concrete strength test, flying stones may damage the dust suction pipe arranged next to the detection device. The flying stones may have a certain impact force. If they directly hit the dust suction pipe, they may cause damage or deformation of the dust suction pipe. Therefore, a strength test device for concrete experiments is proposed to solve the above problems. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-4 In this embodiment, a strength detection device for concrete experiments includes a base 1, a mounting frame 2 is fixedly connected to the top of the base 1, a chassis 3 is fixedly connected to one side of the base 1, a sensing base 4 is embedded in the top of the base 1, a cylinder 5 is fixedly installed on the mounting frame 2, and a protective cleaning mechanism 7 is provided on the base 1.

By providing the protective cleaning mechanism 7, while achieving the protective function, it is also convenient to clean the generated stones and debris. When the cylinder 5 moves downward, it will drive the baffle 703 to move downward, and the baffle 703 will block the dust outlet 704 to prevent stones from splashing onto the dust hood 705 and damaging the dust hood 705. At the same time, the protective cover 701 and the mounting plate 702 can provide protection and blocking in other directions to prevent stones from splashing. After the bottom of the baffle 703 contacts the base 1, due to the setting of the slide groove 709 and the slider 710, the mounting plate 702 will continue to move downward, and the movement of the mounting plate 702 will not be affected by the setting of the baffle 703. When the detection is completed, the cylinder 5 drives the baffle 703 and the mounting plate 702 to move upward, exposing the dust hood 705. At this time, the vacuum cleaner 708 can be turned on to clean the debris and dust inside the protective cover 701, which is easy to operate.

[0026] Specifically, the dust hood 705 covers the outside of the dust outlet 704, and the dust hood 705 is connected to the inside of the protective cover 701 through the dust outlet 704. The debris and dust inside the protective cover 701 will move from the dust outlet 704 to the dust hood 705 and then be sucked into the dust box 707.

[0027] During implementation, follow these steps:

[0028] 1) Place the stone to be tested on the sensing base 4, start the cylinder 5 to drive the pressing block 6 to move downward to test the concrete block, and at the same time drive the baffle 703 to move downward, which will block the dust outlet 704;

[0029] 2) The protective cover 701 and the mounting plate 702 then seal the test environment to prevent stones from flying;

[0030] 3) Finally, when the inspection is completed, the cylinder 5 drives the baffle 703 and the mounting plate 702 to move upward to expose the dust cover 701. At this time, the vacuum cleaner 708 can be turned on to clean the debris and dust inside the protective cover 701.

[0031] In summary, the strength testing device for concrete experiments, by providing a protective cleaning mechanism 7, can realize the protective function while also facilitating the cleaning of generated stones and debris. When the cylinder 5 moves downward, it will drive the baffle 703 to move downward.

At the same time, the protective cover 701 and the mounting plate 702 can provide protective blocking in other directions to prevent stones from splashing. When the test is completed, the cylinder 5 drives the baffle 703 and the mounting plate 702 to move upward. At this time, the vacuum cleaner 708 can be turned on to clean the debris and dust inside the protective cover 701. The operation is simple, and the problem that the dust collection tube is easily damaged by stones when the comparative device is in use is solved.
