The directional words that appear in the present utility model are to better illustrate the characteristics of the features and the relationship between the features. It should be understood that when the placement direction of the present utility model changes, the characteristics of the features and the direction of the relationship between the features also change accordingly. Therefore, the directional words do not constitute an absolute limitation on the characteristics of the features and the relationship between the features in space, but only play a relative limitation role.

[0036] like Figures 1 to 15 As shown, the utility model provides a device for automatically testing the compressive strength of a concrete test block, comprising:

[0037] The transport mechanism includes a clamping assembly 3 and a feeding assembly 2, wherein the feeding assembly 2 is used to transport the concrete test block to be tested, and the clamping assembly 3 is used to clamp the concrete test block on the feeding assembly 2 and transport it to the area to be tested;

[0038] The detection mechanism includes a pressure detection component 1 and a protection component 6. The pressure detection component 1 includes a detection bracket 101, a lower pressure plate 103 and a hydraulic drive component 102.

The auxiliary bracket 601 is installed on the detection bracket 101, and an auxiliary guide rail 605 and a lining plate driving component 604 are installed on the auxiliary bracket 601. The lining plate driving component 604 is used to drive the protection lining plate 602 to slide on the auxiliary guide rail 605, and the protection lining plate 602 can be driven by the lining plate driving component 604 to approach or move away from the lower pressure plate 103; the area to be detected is arranged on the lower pressure plate 103;

[0039] The cleaning mechanism 4 is used to clean the concrete test block residues remaining on the lower pressing plate 103 after the test.

[0040] With the above-mentioned design scheme, after the concrete test block is placed on the lower pressure plate 103, the protective lining 602 is extended to cover the lower pressure plate 103 under the drive of the lining driving component 604. During the pressure test, as the hydraulic driving component 102 continues to apply pressure, the lower pressure plate 103 cooperates with the ball head assembly 106 to continuously squeeze the concrete test block. The flying debris after being squeezed will be intercepted by the protective lining 602 to prevent the flying debris from hurting others. At the same time, the debris can be confined within the range of the lower pressure plate 103, reducing the tediousness of cleaning.

[0041] In this embodiment, the feeding component 2 includes a feeding trolley 201, on which a protrusion 202 is provided; the clamping component 3 includes a robot base 301, a clamping robot 302 and a clamping assembly 303, the clamping robot 302 is installed on the robot base 301, the clamping assembly 303 is installed at the end of the clamping robot 302, and a photoelectric switch 304 is provided at the clamping assembly 303.

The worker pushes the feeding cart 201 loaded with concrete test blocks to the preset position, and the clamping robot 302 automatically clamps the concrete test blocks according to the preset program. The participation of the clamping robot 302 reduces the degree of manual participation, thereby reducing the required labor costs.

[0043] In this embodiment, the cleaning mechanism 4 includes a cleaning frame 401, a guide shaft guide rail 403, a push plate 404 and a material plate driving component 402; the guide shaft guide rail 403 and the material plate driving component 402 are installed on the cleaning frame 401, and the material plate driving component 402 is used to push the push plate 404 to slide on the guide shaft guide rail 403.

The cleaning push block 405 is used to push larger concrete waste slag on the lower pressure plate 103, and the cleaning brush 406 is used to clean smaller concrete waste debris on the lower pressure plate 103.

[0044] In this embodiment, a detachable protective brush 603 is provided on the protective liner 602 .

[0045] Through the above design, when the two protective liners 602 are close to each other and cover the lower pressure plate 103, the protective brushes 603 will overlap each other to ensure that waste slag cannot fly out from the intersection of the two protective liners 602, thereby ensuring the safety of workers and equipment.

[0046] In this embodiment, a secondary positioning assembly 5 is arranged between the clamping assembly 3 and the pressure detection assembly 1. The secondary positioning assembly 5 includes a secondary positioning platform 501, a positioning drive component 502, a push plate 503 and a baffle 504.

[0047] Through the above design scheme, the baffle 504 on the secondary positioning platform 501 can also perform simple measurements on the concrete test block while performing secondary positioning to confirm whether its volume meets the standard; the clamping robot 302 places the concrete test block on the secondary positioning platform 501, and the positioning drive 502 drives the push plate 503 to push the concrete test block into the baffle 504, and the concrete test block is further positioned by clamping the baffle 504 and the push plate 503.

[0048] In this embodiment, a dust hopper 105 is provided on the detection bracket 101 near the lower pressing plate 103 , and a sample positioning block 104 is provided on the lower pressing plate 103 .

[0050] In this embodiment, a limit switch 109 is provided on the detection bracket 101 .

[0052] Compared with the prior art, the utility model provides a device for automatically testing the compressive strength of a concrete test block. In this way, the clamping robot 302 picks up the concrete test block on the feeding trolley 201, and after positioning it through the secondary positioning component 5, the concrete test block is clamped onto the lower pressure plate 103. After the position of the test block on the lower pressure plate 103 is determined by the sample positioning block 104, the lining plate driving member 604 drives the protective lining plate 602 to extend and cover the lower pressure plate 103. When performing pressure testing, the flying debris will be intercepted by the protective lining plate 602 to protect the safety of equipment and personnel.
