Description

Technical Field

[0001] The present invention belongs to the technical field of testing equipment, and particularly relates to a fully automatic concrete flexural and compressive strength testing equipment. Background Technique

[0002] As the core material of modern construction projects, the mechanical property testing of concrete is a key link to ensure the quality and safety of projects. Flexural strength and compressive strength are the core indicators for evaluating the quality of concrete, which are directly related to the durability and load-bearing capacity of building structures. Traditional testing methods mainly rely on manual operation, suffering from problems such as low efficiency, high error rate, and scattered data management. In recent years, with the development of automation technology, related testing equipment has gradually evolved towards the intelligent direction.

[0003] However, it is found during use that when the current flexural testing equipment detects workpieces, there is no mechanism to clamp the concrete specimens. As a result, during flexural testing, the position of the specimens changes. Further, when breaking, the two broken parts of the concrete may still splash, and the splashing specimens may damage the equipment or injure people. Summary of the Invention

[0004] Aiming at the problems raised in the above background technique, the purpose of the present invention is to provide a fully automatic concrete flexural and compressive strength testing equipment.

[0005] To achieve the above technical purpose, the technical solution adopted by the present invention is as follows:

[0033] In order to enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0034] As Figures 1 to 5 shown, a full-automatic concrete flexural and compressive strength testing device of the present invention includes a frame 1, a support rod 2 is installed on the frame 1, a top plate 3 is installed at the top of the support rod 2, and a flexural strength testing mechanism 4 and a compressive strength testing mechanism 5 are installed on the frame 1;

[0035] The flexural strength testing mechanism 4 includes a first hydraulic cylinder 41 fixedly installed on the top plate 3 and a base 42 fixedly installed on the frame 1. The base 42 is U-shaped. Chutes 43 are provided on both sides of the base 42. A front slider 44 and a rear slider 45 are slidably installed in the chutes 43. The lower end of the front slider 44 is connected to an upper rack 46, and the lower end of the rear slider 45 is connected to a lower rack 47. The upper rack 46 and the lower rack 47 are parallel to each other. A rotating shaft 48 is rotatably installed in the chute 43. A circular gear 49 is fixedly installed on the rotating shaft 48. The circular gear 49 meshes with both the upper rack 46 and the lower rack 47. A driven gear 410 is fixedly installed on a section of the rotating shaft 48 passing through the base 42;

[0036] The output end of the first hydraulic cylinder 41 is connected to a lifting plate 411. The output end of the lifting plate 411 is connected to a pressing roller 412. Vertical rods 413 corresponding to the driven gear 410 in position are connected to both sides of the lifting plate 411. Blind holes 414 are provided in the vertical rods 413. A connecting rod 415 is slidably installed in the blind holes 414. A collar 416 is fixedly installed on the connecting rod 415. The collar 416 is located in the blind hole 414. A sealing plate 417 is fixedly installed on the vertical rod 413. The sealing plate 417 is sleeved outside the connecting rod 415. The collar 416 cannot pass through the sealing plate 417. A spring 418 is installed between the blind hole 414 and the collar 416. A driving rack 419 is fixedly installed on the lower side of the connecting rod 415. The driving rack 419 meshes and matches with the driven gear 410;

[0037] The compressive strength testing mechanism 5 includes a second hydraulic cylinder 51 fixedly installed on the top plate 3 and a base 52 fixedly installed on the frame 1. A placing tray 53 is installed on the top of the base 52, and the output end of the second hydraulic cylinder 51 is connected to a pressing plate 54.

[0038] In this embodiment, when using a fully automatic concrete flexural and compressive strength testing equipment, the concrete specimen is directly placed on the base 42, and then the first hydraulic cylinder 41 is directly operated. It should be noted that the pressure data of the first hydraulic cylinder 41 and the second hydraulic cylinder 51 are monitored and controlled by the control terminal in real time. When the pressure of the first hydraulic cylinder 41 suddenly decreases, it is when the concrete specimen breaks, so as to detect the anti-breaking ability of the concrete specimen.

[0039] When the first hydraulic cylinder 41 operates, it drives the lifting plate 411 to descend. The descent of the lifting plate 411 drives the vertical rod 413 to move downward. Under the effect of the spring 418, the downward movement of the vertical rod 413 pushes the connecting rod 415 to move downward. Then, the driving rack 419 connected to the lower end of the connecting rod 415 moves downward, driving the driven gear 410 to rotate. The rotation of the driven gear 410 drives the upper rack 46 and the lower rack 47 to move relative to each other. Furthermore, the front slider 44 and the rear slider 45 approach each other under the limitation of the chute 43, thereby realizing the clamping of the concrete test. Moreover, after the clamping is completed, the continuous descent of the vertical rod 413 will not be interfered under the compression effect of the spring 418, and thus will not interfere with the contact between the pressure roller 412 and the concrete specimen. When the pressure roller 412 contacts the concrete specimen, the flexural test of the concrete specimen can be realized. After obtaining the flexural data, the first hydraulic cylinder 41 retracts. Under the effect of the sealing plate 417 and the collar 416, the rising of the vertical rod 413 will drive the connecting rod 415 to rise, and then drive the driving rack 419 to drive the driven gear 410 to rotate back, releasing the clamping of the concrete specimen, facilitating the removal of the concrete specimen and the placement of the next one.

[0040] After the flexural test is completed, the concrete specimen is placed on the placing tray 53, and the second hydraulic cylinder 51 is controlled to operate, driving the pressing plate 54 to descend, so that the pressing plate 54 contacts the concrete specimen, and the compressive data of the concrete specimen can be obtained.

[0041] In summary, the flexural and compressive strength testing of the concrete is completed.
