The pressing plate 35 is fixedly connected to the lower ends of the sliding rods 34. The control panel 36 is bolted to the right top portion of the mounting frame 2. The control panel 36 is electrically connected to the stepping motor 22 and the hydraulic cylinder 32.
[0019] As shown in Figure 1 and Figure 2 The fence assembly comprises an L-shaped plate 41, a return spring 42 and a shielding frame 43. The L-shaped plates 41 are slidably arranged on the sliding rods 34. The return springs 42 are connected between the L-shaped plates 41 and the pressing plate 35. The return springs 42 are sleeved on the outer sides of the adjacent sliding rods 34. The shielding frame 43 is fixedly connected between the L-shaped plates 41 by bolts. The shielding frame 43 is made of transparent material, which facilitates the real-time observation of the bricks by the workers to determine whether the bricks are cracked. The height between the bottom of the shielding frame 43 and the bottom of the pressing plate 35 is slightly greater than the height of the bricks. In this way, when the pressing plate 35 moves downward, the shielding frame 43 first contacts the bottom plate 1, and then the pressing plate 35 contacts the bricks.
[0020] In use, the staff first place three concrete blocks to be tested on the top of the base plate 1, then start the stepping motor 22 through the control panel 36, the stepping motor 22 drives the lead screw 21 to rotate, and then pushes the I-shaped plate 31 to slide left and right on the upper part of the mounting frame 2, adjusts the position of the I-shaped plate 31, and moves the lower pressing plate 35 above the leftmost brick, at this time, the staff starts the hydraulic cylinder 32, the piston rod of the hydraulic cylinder 32 extends, pushes the lower pressing plate 35 to move stably downward under the guidance of the sliding rod 34, until it contacts the top of the leftmost brick, the hydraulic cylinder 32 continues to work, and continuously outputs the pressing force to the brick through the lower pressing plate 35, until the brick is cracked, in the process, the staff can record the specific pressure value required to crack the brick on the control panel 36, after the test is completed, control the hydraulic cylinder 32 to retract through the control panel 36, so that the lower pressing plate 35 resets, then start the stepping motor 22 again, adjust the position of the lower pressing plate 35, move it to the top of the middle and right bricks, and repeat the above test steps to test the other two bricks.
