DETAILED DESCRIPTION

[0025] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0026] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0027] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0028] like Figures 1 to 5The concrete pressure testing machine shown in the figure includes a base 1, a groove 2 is provided on the top surface of the base 1, a rectangular groove 3 is provided on the bottom surface of the inner cavity of the groove 2, the diameter of the rectangular groove 3 is smaller than the diameter of the groove 2, a placing table 4 for placing a concrete block is provided in the inner cavity of the groove 2, and a support plate 5 is symmetrically welded to the bottom surface of the inner cavity of the rectangular groove 3, and the bottom surfaces of the two support plates 5 are welded to the bottom surface of the inner cavity of the rectangular groove 3. Through the support plate 5, the placing table 4 can be set in the inner cavity of the groove 2, and the top surface of the placing table 4 is at the same horizontal height as the top surface of the base 1. A protective cover 6 is provided in the inner cavity of the groove 2 and on the outside of the placing table 4. A first hydraulic cylinder 8 is fixedly installed on the bottom surface of the inner cavity of the rectangular groove 3, and the piston rod of the first hydraulic cylinder 8 is fixedly connected to the bottom surface of the protective cover 6. When the concrete block is placed on the top surface of the placing table 4, the first hydraulic cylinder 8 is turned on, and the first hydraulic cylinder 8 drives the protective cover 6 to move in the inner cavity of the groove 2, and moves around the support plate 5 through the empty groove 7, so that the top surface of the protective cover 6 passes through the groove 2 and covers the concrete block on the top surface of the placing table 4, and makes the top surface of the protective cover 6 close to the bottom surface of the top cover 14, so that a sealed space is formed inside the protective cover 6, which can prevent the concrete block from being broken and fragmented due to pressure from splashing around, thereby not damaging the attached equipment and the attached staff, and improving the safety of the staff at work. The height of the groove 2 is adapted to the height of the protective cover 6. When the first hydraulic cylinder 8 drives the protective cover 6 to enter the groove 2, the bottom surface of the protective cover 6 is allowed to contact the bottom surface of the inner cavity of the groove 2, so that the top surface of the protective cover 6 and the top surface of the base 1 are at the same horizontal height, which is convenient for the subsequent treatment of the stones left on the top surfaces of the placing table 4 and the base 1. The first hydraulic cylinder 8 is arranged in the inner cavity of the rectangular groove 3, so that the bottom surface of the protective cover 6 can contact the bottom surface of the inner cavity of the groove 2. Due to the arrangement of the support plate 5 and the empty groove 7, the first hydraulic cylinder 8 can be fixedly installed between the two support plates 5, so that the protective cover 6 will not affect the support plate 5 and the placing table 4 when it moves upward.

[0029] A support block 9 is fixedly connected to one side of the base 1, and a transverse groove 10 is penetrated on one side of the support block 9. The bottom surface of the inner cavity of the transverse groove 10 is at the same horizontal height as the top surface of the base 1. A connecting box 11 is fixedly connected to one side of the support block 9 away from the base 1 and located on one side of the transverse groove 10. A first cylinder 12 is fixedly installed on the side of the connecting box 11 away from the support block 9. The piston rod of the first cylinder 12 penetrates the connecting box 11 and is fixedly connected to a shovel plate 13. After the concrete block is tested and the placement table 4 is removed, the first cylinder 12 can be turned on, so that the first cylinder 12 drives the shovel plate 13 to move, and then the shovel plate 13 passes through the transverse groove 10 and fits the top surface of the base 1 to clean the remaining stones, so as to prevent the stones remaining on the top surface of the base 1 and the placement table 4 from affecting the placement of the next concrete block.

[0030] The top surface of the support block 9 is fixedly connected to a top cover 14, and a second hydraulic cylinder 15 is fixedly installed on the top surface of the top cover 14. The piston rod of the second hydraulic cylinder 15 passes through the top cover 14 and is fixedly connected to a pressure plate 16 for applying pressure to the concrete. A through groove 17 is provided on the bottom surface of the top cover 14 for the pressure plate 16 to pass through. When the protective cover 6 is close to the top cover 14, the second hydraulic cylinder 15 can be opened, and the second hydraulic cylinder 15 drives the pressure plate 16 to move downward, and allows the pressure plate 16 to squeeze the concrete block placed on the top surface of the placement table 4 through the through groove 17, thereby performing a pressure test on the concrete block.

[0031] A second cylinder 19 is fixedly installed on one side of the top cover 14. The piston rod of the second cylinder 19 penetrates the top cover 14 and is fixedly connected with a sweeping plate 20 for sweeping stone particles on the bottom surface of the pressure plate 16. A brush can be installed on the top surface of the sweeping plate 20, and the top surface of the sweeping plate 20 is at the same horizontal height as the bottom surface of the pressure plate 16. Vertical plates 18 are installed on the bottom surface of the inner cavity of the top cover 14 and on both sides of the through groove 17. A through groove 21 for the sweeping plate 20 to pass through is penetrated on one side of one of the vertical plates 18. After the pressing plate 16 completes the test on the concrete block, the second hydraulic cylinder 15 drives the pressing plate 16 to pass through the through slot 17 into the inner cavity of the top cover 14, and after the top surface of the pressing plate 16 is pressed against the bottom surfaces of the two vertical plates 18, the second cylinder 19 is turned on, so that the second cylinder 19 drives the sweeping plate 20 to pass through the through slot 21, and the sweeping plate 20 drives the brush to reciprocate on the bottom surface of the pressing plate 16, so as to clean the stone particles adhering to the bottom surface of the pressing plate 16, so as to avoid affecting the pressure on the concrete block next time.

[0032] Working principle:

[0033] The concrete pressure testing machine places a concrete block on the top surface of the placement table 4, and then starts the first hydraulic cylinder 8, which drives the protective cover 6 to move upward, so that the protective cover 6 passes through the groove 2 and wraps the concrete block on the top surface of the placement table 4, and continues to drive the protective cover 6 to move upward, so that the top surface of the protective cover 6 can be pressed against the bottom surface of the top cover 14, so that a sealed space is formed on the top surface of the placement table 4. At this time, the second hydraulic cylinder 15 is started, and the second hydraulic cylinder 15 drives the pressure plate 16 to move downward, so as to apply pressure to the concrete block. Since the protective cover 6 wraps the concrete block, the broken fragments produced by the pressure on the concrete block will not splash around, thereby avoiding damage to the attached equipment or the attached staff, thereby providing safety for the staff at work.
