The bottom of the concrete placing plate 1 is fixedly connected to the top of the supporting and balancing chassis 10, and the top of the supporting and balancing chassis 10 is fixedly connected to the bottom of the U-shaped supporting frame 12. The cooperation of the supporting and balancing chassis 10 and the U-shaped supporting frame 12 can effectively ensure the smooth progress of the pressure test and is not easy to tip over.

[0027] See also Figure 4 A first limiting single rod 13 is fixedly arranged in a groove on one side of the inner wall of the U-shaped supporting frame 12. There are two groups of the first limiting single rod 13. The outer circumferential surface of the first limiting single rod 13 is slidably connected to the middle part of the linkage balance board 14. The setting of two groups of first limiting single rods 13 can effectively ensure the stability of the linkage balance board 14, so that the linkage balance board 14 is not prone to tilting. The top of the linkage balance board 14 is fixedly connected to the bottom of the second limiting single rod 17. There are two groups of the second limiting single rod 17. The setting of multiple groups of second limiting single rods 17 further enhances the stability of the linkage balance board 14 during movement.

[0028] See also Figure 4 The bottoms of the two groups of second limiting single rods 17 are fixedly connected to the top of the linkage balance plate 14, and the outer circumferential surfaces of the two groups of second limiting single rods 17 are respectively sleeved with tough springs 19. There are two groups of tough springs 19. The top of the second limiting single rod 17 is fixedly connected to the bottom of the control top cap 18, and the bottom of the control top cap 18 is fixedly connected to the top of the tough spring 19. The bottom of the tough spring 19 is fixedly connected to the top of the U-shaped support frame 12. The setting of multiple groups of tough springs 19, utilizing the elasticity of the tough springs 19 themselves, can effectively prevent the linkage balance plate 14 from excessive movement through the second limiting single rod 17, thereby avoiding the problem of collision between components.

[0029] See also Figure 4The outer circumferential surface of the second limiting single rod 17 is slidably connected to the groove in the middle of the U-shaped support frame 12, and a pressure detection module 15 is fixedly connected to the middle of the linkage balance plate 14. The pressure detection module 15 is a prior art and will not be described in detail. The setting of the pressure detection module 15 can effectively detect the compressive resistance of the test block. The top of the pressure detection module 15 is fixedly connected to one end of the electric one-way cylinder 16, and the bottom of the electric one-way cylinder 16 is fixedly connected to the top of the U-shaped support frame 12. The electric one-way cylinder 16 is a prior art and will not be described in detail.

[0030] See also Figure 1 The bottom of the supporting balancing chassis 10 is fixedly connected to the top of the supporting balancing base 11. There are four groups of supporting balancing bases 11, and the four groups of supporting balancing bases 11 are evenly distributed at the bottom of the supporting balancing chassis 10. The purpose of setting multiple groups of supporting balancing bases 11 is to effectively ensure the overall stability of the concrete press, prevent it from tilting, and ensure the smooth progress of the pressure test.

[0031] See also Figure 1 and Figure 2 The bottom of the inner wall of the concrete placing plate 1 is rotatably connected to the bottom of the plane worm wheel 2, the teeth on the outer circumferential surface of the plane worm wheel 2 are meshed with the threads on the outer circumferential surface of the one-way worm 8, and the one-way worm 8 is rotatably arranged inside the concrete placing plate 1. The close fit between the plane worm wheel 2 and the one-way worm 8 can effectively drive the movement of subsequent components, and at the same time has a self-locking effect to avoid rebound.

[0032] See also Figure 1 , Figure 2 and Figure 3 One end of the one-way worm 8 is fixedly connected to one side of the external driving disk 9, the top of the planar worm wheel 2 is fixedly connected to the bottom of the guide limiting disk 3, and a guide control groove 4 is opened in the middle of the guide limiting disk 3. The setting of the guide limiting disk 3 and the guide control groove 4 can effectively ensure that the subsequent components move in the direction of the guide control groove 4.

[0033] See also Figure 2 and Figure 3 A limiting guide top plate 7 is fixedly connected to the middle of the concrete placement plate 1, and a groove in the middle of the limiting guide top plate 7 is slidably connected to the outer wall of the test block limiting fixture 6.

A linkage limit column 5 is fixedly connected to the bottom of the test block limiting fixture 6, and the linkage limit column 5 is located in the guide control groove 4. The setting of the linkage limit column 5 can effectively ensure that subsequent components move accordingly.

[0034] Working principle: Place the test block in the concrete placement plate 1, and use external power to rotate the external drive plate 9, driving the flat worm wheel 2 on one side of the one-way worm 8 to rotate in situ in the concrete placement plate 1, so that the guide limit plate 3 rotates accordingly. Under the restriction of the guide control groove 4 on the guide limit plate 3, the linkage limit column 5 under the test block limit fixture 6 moves in the direction of the guide control groove 4. At the same time, the test block limit fixture 6 is restricted by the restriction guide top plate 7, so that the test block limit fixture 6 slides horizontally on the restriction guide top plate 7, so that the test block limit fixture 6 and the test The test block contacts to form a limiting effect, and then the electronically controlled one-way cylinder 16 is started to work, pushing the pressure detection module 15 to move vertically downward, driving the linkage balance plate 14 to slide on the first limiting single rod 13, and at the same time, the movement of the linkage balance plate 14 will also drive the control top cap 18 on the second limiting single rod 17 to move, thereby compressing the toughness spring 19. Under the elastic characteristics of the toughness spring 19 itself, excessive movement of the linkage balance plate 14 can be effectively avoided. At this time, the pressure detection module 15 will gradually compress the test block, thereby detecting the pressure resistance of the test block.
