[0031] When conducting an experiment, the concrete test block is manually placed on the workbench 1, and then the clamping mechanism 4 clamps the concrete test block. At this time, the pressing mechanism 2 presses down to apply pressure to the concrete test block. At this time, the anti-splashing mechanism 3 shields the pressure-applying position of the concrete test block, and then the dust-proof mechanism 7 is started to collect the dust generated when the concrete test block is crushed; when the concrete test block is crushed, the clamping mechanism 4 recovers it, and then drives the cleaning mechanism 5 through the transmission mechanism 6 to clean the broken concrete test block.

[0032] refer to Figure 2 The pressing mechanism 2 includes a first mounting plate 21, which is fixedly connected to the workbench 1, and a second mounting plate 22 is fixedly connected to one end of the first mounting plate 21 away from the workbench 1, and a hydraulic cylinder 23 is fixedly connected to one end of the second mounting plate 22 away from the workbench 1, and a pressure block 24 is fixedly connected to the piston shaft of the hydraulic cylinder 23, and a pressure sensor 25 is fixedly connected to the end surface of the pressure block 24 close to the workbench 1; when the concrete test block is pressurized, the hydraulic cylinder 23 is started, and the hydraulic cylinder 23 drives the pressure block 24 to move toward the concrete test block through the piston shaft and makes the pressure block 24 abut against the concrete test block, and the pressure block 24 crushes the concrete test block.

[0033] refer to Figure 3 and Figure 4 The anti-splashing mechanism 3 includes a left shielding box 31 and a right shielding box 32. The end surfaces of the left shielding box 31 and the right shielding box 32 that are close to each other are both provided with annular grooves. The anti-splashing mechanism 3 also includes a fixing assembly 33. The fixing assembly 33 includes two first fixing plates 331. The two first fixing plates 331 are both fixedly connected to the left shielding box 31 and are respectively located at the two ends of the left shielding box 31.

The fixing assembly 33 also includes two first fixing bolts 333. The first fixing bolts 333 are respectively passed through the two first penetration holes in sequence and are threadedly connected with fixing nuts 334.

[0034] By setting the left shielding box 31 and the right shielding box 32, the shielding position when the concrete test block is broken becomes smaller, and only the concrete test block and the pressure block 24 are covered, thereby reducing the splashing radius when the concrete test block is broken, reducing the probability of the splashing concrete test block contaminating the workbench 1; at the same time, the setting of the first fixing bolt 333 and the fixing nut 334 realizes the fixation of the left shielding box 31 and the right shielding box 32, so that the left shielding box 31 and the right shielding box 32 can be lowered to the workbench 1 as the pressure block 24 descends to shield the broken concrete test block, and also facilitates the replacement of the left shielding box 31 and the right shielding box 32.

[0035] refer to Figure 3 and Figure 5An air outlet is provided on the side wall of the right shielding box 32 away from the workbench 1, and the dust-proof mechanism 7 includes a collecting hose 71, which is fixedly connected to the air outlet.

[0036] When the experiment is carried out, the fan 73 is started, and the fan 73 draws the dust generated by the crushing of the concrete test block into the dust collection box 72 through the collection hose 71, thereby reducing the probability of the dust generated by the crushing of the concrete test block polluting the working environment.

Clamping blocks 42 are fixedly connected to the piston shafts of the two cylinders 41, and rubber pads 43 are fixedly connected to the end surfaces of the two clamping blocks 42 close to each other; when the concrete test block is clamped, the two cylinders 41 are started, and the two cylinders 41 respectively drive the two clamping blocks 42 to approach each other, and then the clamping blocks 42 clamp the concrete test block through the rubber pads 43, which reduces the probability of inaccurate experimental results caused by the sliding of the concrete test block during the compression test. At the same time, the setting of the rubber pads 43 increases the friction between the clamping blocks 42 and the concrete test block, further reducing the probability of sliding of the concrete test block.

[0038] refer to Figure 6 , Figure 7 and Figure 8 A collecting groove 11 is provided on the side wall of the workbench 1, and a through groove 12 connected to the collecting groove 11 is also provided on the end surface of the workbench 1 close to the hydraulic cylinder 23.

[0039] When cleaning the broken concrete test blocks on the workbench 1, the cylinder 41 contracts, and the cylinder 41 drives the two lead screws 521 to rotate through the transmission mechanism 6. The two lead screws 521 drive the two first sliders 522 to slide. The two first sliders 522 respectively drive the two cleaning brushes 51 to clean the broken concrete test blocks on the workbench 1 into the through groove 12.

[0041] The setting of the sealing plate 552 blocks the through groove 12, reducing the probability that the concrete test block at the position of the through groove 12 will not receive the support force and will be unevenly stressed when conducting experiments, thereby reducing the probability of inaccurate experimental results. At the same time, when cleaning, the retraction of the cylinder 41 drives the sealing plate 552 to move through the second connecting rod 551, thereby opening the through groove 12, without affecting the cleaning of the broken concrete test block.

[0046] The implementation principle of a building component strength test device according to an embodiment of the present application is as follows: when conducting a strength test of a concrete test block, the concrete test block is first manually placed on the workbench 1, and then the air cylinder 41 is started, and the cylinder 41 drives the clamping block 42 to clamp the concrete test block, and then the hydraulic cylinder 23 is started, and the hydraulic cylinder 23 drives the pressing block 24 to descend to abut against the concrete test block. At this time, the left shielding box 31 and the right shielding box 32 shield the connection between the concrete test block and the pressing block 24, and then the hydraulic cylinder 23 continues to pressurize to crush the concrete block. At this time, the pressure sensor 25 collects the pressure during crushing, and the fan 73 is started to suck the dust generated during crushing into the dust collection box 72. ; Then the hydraulic cylinder 23 contracts, and the cylinder 41 also contracts at the same time.
