[0031] Reference Figure 1 , 45. An inclined drainage plate 19 is provided at the top of the inner cavity of the testing platform 1, which is located below the clamp 10. A rubber soft ring 20 is bonded to the outer periphery of the drainage plate 19, and the outer ring of the rubber soft ring 20 is bonded to the inner wall of the testing platform 1. A recovery platform 21 is fixedly installed on the right side of the testing platform 1, which is located below the right side of the drainage plate 19. A pumping box 22 is slidably installed on the right side of the recovery platform 21. A vibrator 23 is fixedly installed at the bottom of the drainage plate 19. A No. 2 motor 24 is fixedly installed on the left side of the vibrator 23. A special-shaped rotating rod 25 is fixedly installed on the output shaft of the No. 2 motor 24. Multiple sets of sleeve rods 26 are sleeved on the special-shaped rotating rod 25. A linkage rod 27 is hingedly installed on the top of the sleeve rod 26.

A counterweight plate 30 is fixedly installed on the top of the plug rod 29.

[0032] By setting the drainage plate 19, since the explosion-proof cover 16 resists the shattered concrete fragments, the fragments fall onto the top of the drainage plate 19, and then the No. 2 motor 24 in the vibrator 23 below the drainage plate 19 is started. The No. 2 motor 24 drives the special-shaped rotating rod 25 to rotate, so that the special-shaped rotating rod 25 drives the counterweight plate 30 on the top of the plug 29 to move up and down rapidly through the linkage rod 27, so as to generate a certain vibration to the drainage plate 19, and then the concrete fragments falling on the drainage plate 19 are shaken off and rolled into the drawer 22 on the recovery platform 21 to receive them, so as to facilitate the rapid cleaning of the concrete fragments.

[0033] The implementation principle of the steel fiber reinforced epoxy resin rubber concrete fracture performance test device and method embodiment of the present application is: When using the device, first of all, when using the device, it is necessary to move the device to the detection site, start the electric push rod 6 to retract, and then the support rod 5 on the extended end of the electric push rod 6 will move upward with the electric push rod 6, so that the rollers 3 at the four ends of the bottom of the detection platform 1 can touch the ground, and then the device can be pushed into the detection site.

After the concrete test block is fixed, if necessary, the external extensometer can be fixed to the upper and lower sides of the concrete test block through the fixing parts, and then a start The motor 18 drives the threaded rod 17 to rotate, and then controls the slide plate 15 to drive the explosion-proof cover 16 to move downward, so that the explosion-proof cover 16 covers the front side and the top of the enclosure 7, and finally starts the hydraulic rod 8 to contract. At this time, the four clamping plates 12 will clamp and pull the concrete test block until the concrete test block finally breaks, and the broken concrete fragments will be blocked by the explosion-proof cover 16 to prevent them from splashing and injuring the experimenters or surrounding instruments. In this process, the tension sensor 9 and the external extensometer transmit the experimental data to the computer for storage.

[0035] In addition, since the explosion-proof cover 16 has blocked the shattered concrete fragments, the fragments fall onto the top of the drainage plate 19 at this time, and then the No. 2 motor 24 in the vibrator 23 below the drainage plate 19 is started, and the No. 2 motor 24 drives the special-shaped rotating rod 25 to rotate, so that the special-shaped rotating rod 25 drives the counterweight plate 30 on the top of the plug 29 to continuously move up and down quickly through the linkage rod 27, so as to generate a certain vibration to the drainage plate 19, and then the concrete fragments falling on the drainage plate 19 are shaken off and rolled into the drawer 22 on the recovery platform 21 to receive them, so as to facilitate the rapid cleaning of the concrete fragments.

In the present invention, by setting a base, when using the device, it is necessary to first move the device to the detection site, start the electric push rod to retract, and then the support rod on the extended end of the electric push rod will move upward with the electric push rod, so that the rollers at the four ends of the bottom of the detection table can touch the ground, and then the device can be pushed into the detection site. After arriving, start the electric push rod to extend, and then the support rod moves downward to touch the ground. At this time, the rollers are raised, and the device can be fixed on the base surface.

At this time, the clamping discs on the inner side of the clamping rods are close to and clamp the upper and lower ends of the concrete test block. After the concrete test block is fixed, if necessary, the external extensometer can be fixed to the upper and lower sides of the concrete test block through the fixing parts, and then the No. 1 motor is started to drive the threaded rod to rotate, thereby controlling the slide plate to drive the explosion-proof cover to move downward, so that the explosion-proof cover covers the front side and the top of the enclosure, and finally the hydraulic rod is started to contract. At this time, the four clamping discs will clamp and pull the concrete test block until the concrete test block is finally broken, and the broken concrete fragments will be blocked by the explosion-proof cover to prevent them from splashing and injuring the experimenters or surrounding instruments.

After arriving at the testing location, start the electric push rod (6) to extend, and then the support rod (5) moves downward to touch the ground. At this time, the rollers (3) are raised, and the device can be fixed on the base surface. S2: After the device is fixed, the upper and lower ends of the steel fiber reinforced epoxy resin rubber concrete test block are respectively placed in the middle of the front side of the two clamps (10), and then the double-headed motor (14) is started to drive the two screws (13) to rotate, thereby driving the two clamping rods (11) to move towards each other, and then the clamping plate (12) inside the clamping rod (11) approaches and clamps the upper and lower ends of the concrete test block; S3: After the concrete test block is fixed, if necessary, the external extensometer can be fixed to the upper and lower sides of the concrete test block through the fixing parts, and then the No. 1 motor (18) is started to drive the threaded rod (17) to rotate, and then the slide plate (15) is controlled to drive the explosion-proof cover (16) to move downward, so that the explosion-proof cover (16) covers the front side and the top of the enclosure (7), and finally the hydraulic rod (8) is started to shrink. At this time, the four clamping plates (12) will clamp and pull the concrete test block until the concrete test block is finally broken, and the broken concrete fragments will be blocked by the explosion-proof cover (16) to prevent them from splashing and injuring the experimenters or surrounding instruments. In this process, the tension sensor (9) and the external extensometer transmit the experimental data to the computer for storage; S4: As the explosion-proof cover (16) resists the concrete fragments that are shattered and splashed, the concrete fragments fall onto the top of the drainage plate (19), and then the second motor (24) in the vibrator (23) below the drainage plate (19) is started, and the second motor (24) drives the special-shaped rotating rod (25) to rotate, so that the special-shaped rotating rod (25) drives the counterweight plate (30) on the top of the plug rod (29) to move up and down rapidly through the linkage rod (27), so as to generate a certain vibration on the drainage plate (19), and then the concrete fragments that fall on the drainage plate (19) are shaken off and rolled into the drawer box (22) on the recovery platform (21) to receive them, so as to facilitate the rapid cleaning of the concrete fragments.
