Four card slots 11 are opened at the bottom of the lifting block 10, and a second motor 12 is installed on the top of the lifting block 10. A connecting bolt 13 is installed at the bottom end of the output shaft of the second motor 12 that penetrates the bottom of the lifting block 10, and a gravity block 14 is movably installed on the periphery of the two guide rods 9. Four card blocks 15 are fixedly installed on the top of the gravity block 14, and a connecting groove 16 is opened in the center of the top of the gravity block 14.

[0022] In this embodiment, the screw rod 5 and the output shaft of the first motor 7 are arranged to rotate synchronously, and the lifting block 10 is sleeved on the outer periphery of the screw rod 5 and is threadedly connected. The screw rod 5 drives the lifting block 10 to slide up and down, lifts the gravity block 14, and performs falling detection at different heights.

[0023] In this embodiment, the gravity block 14 is sleeved on the outer periphery of the guide rod 9 and is slidable up and down. The connecting bolt 13 and the connecting groove 16 are threadedly connected. The gravity block 14 is connected or disconnected from the lifting block 10 through the connecting bolt 13, which is convenient for automatic lifting and falling.

[0024] In this embodiment, the four blocks 15 and the four slots 11 are arranged in a matrix. The blocks 15 are located in the slots 11 and are snap-connected. The bottom of the lifting block 10 contacts the top of the gravity block 14, so that the blocks 15 are snapped into the slots 11 to prevent the gravity block 14 from rotating synchronously with the connecting bolt 13.

[0025] In this embodiment, the protection mechanism 3 includes three protection plates 17, which are respectively installed on the top of the base 1 near both sides and the rear end, and the inner sides of the protection plates 17 on both sides are installed with slide rails 18 near the front end, and a baffle 19 is movably installed between the two slide rails 18. An observation window 20 is provided at the front of the baffle 19, and a support platform 21 is movably installed through the front of the base 1, and wing plates 22 are fixedly installed on both sides of the support platform 21 near the top, and sliders 23 are fixedly installed on both sides of the support platform 21 near the lower end. Slide grooves 24 are provided on the inner walls of both sides of the base 1, and the splashing fragments are blocked by the protection plates 17 to improve the overall protection.

[0026] In this embodiment, the baffle 19 is located between the two slide rails 18 and is slidable up and down. The bottom end of the baffle 19 passes through the top of the base 1 and is clamped near the front end. The interior of the protective plate 17 is opened or closed by sliding the baffle 19 to take, place and protect the concrete sample.

[0027] In this embodiment, the thickness between the upper and lower parts of the support platform 21 is greater than the distance between the top of the base 1 and the ground. The slider 23 is located in the slide groove 24 and is slidably arranged. The support platform 21 is slid through the buckle groove at the front of the support platform 21, so that concrete sample tests and concrete floor tests can be carried out.

[0028] It should be noted that the utility model is a concrete strength testing device for road engineering. When in use, the concrete sample is first placed on the support platform 21, and the strength is tested by the free fall of the gravity block 14. When testing, the support platform 21 is taken out, the slider 23 is separated from the slide slot 24, and the support platform 21 is inserted into the interior of the base 1, so that the bottom of the support platform 21 is in contact with the ground for support, and the first motor 7 is started to make the screw 5 drive the lifting block 10 to slide downward and contact the gravity block 14, so that the card block 15 is carded into the card slot 11, and the second motor 12 is started at the same time to make the connecting bolt 13 rotate and connect with the connecting slot 16, and the first The drive of the motor 7 causes the screw rod 5 to reverse and drive the lifting block 10 to rise, and at the same time, the gravity block 14 rises. When it rises to the specified height, the connecting bolt 13 is rotated to disengage the connecting groove 16, so that the gravity block 14 falls downward under the action of gravity and is prevented from deflecting by the guide rod 9. The gravity block 14 hits the concrete sample for strength testing. The fragments produced by the impact are protected by the protective plate 17 and fall on the top of the support platform 21 and the wing plate 22. By taking out the support platform 21, the gravity block 14 hits the ground, and the strength of the concrete floor can be tested. After the test is completed, the slider 23 is inserted into the slide groove 24 to separate the support platform 21 from the ground for movement and transfer.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
