[0040] As a technical optimization of this utility model, the linkage between the rotating wheel 9 and the shaft 5 is realized by the sliding of the slide rod 11 within the sleeve plate 10.

The receiving frame 12 is sleeved on the surface of the transmission rod 8 and is movably connected to the transmission rod 8.

[0042] As a technical optimization of this utility model, the crushed debris is collected directly by the structure of the detection table 1, reducing the frequency of manual cleaning. The receiving frame 12 and the transmission rod 8 share the same space, avoiding additional occupation of equipment volume.

[0043] refer to Figure 2 A drive motor 13 is fixedly connected to the right side of the receiving frame 12, and the output end of the drive motor 13 is fixedly connected to the right end of the drive rod 8.

[0044] As a technical optimization of this utility model, the pressure plate 6 is rotated and the debris is conveyed by a single motor, which reduces energy consumption and cost. At the same time, the transmission motor 13 drives the entire process of pressing, testing and cleaning to be automated.

[0047] refer to Figure 4 A connecting frame 16 is fixedly connected to the top of the pressure plate 6, and the connecting frame 16 can support the pressure plate 6.

[0048] As a technical optimization of this utility model, the clevis and the pressure plate 6 work together to enhance the fixing effect on the irregularly shaped test object 3. The connecting frame 16 facilitates the installation and replacement of the clevis and adapts to different testing needs.

[0049] refer to Figure 4 A movable block 17 is fixedly connected to the top of the pressure plate 6. A rocker arm 18 is movably connected to the surface of the movable block 17 via a pin. A shielding frame 19, which is sleeved on the surface of the pressure assembly 2, is fixedly connected to the side of the rocker arm 18 away from the movable block 17.

[0050] As a technical optimization of this utility model, the shielding frame 19 swings with the swing arm 18 to cover the pressure component 2, preventing debris from splashing and damaging the equipment. The position of the shielding frame 19 automatically adapts with the movement of the chuck, requiring no additional operation.

[0051] refer to Figure 4 A fork 20 is fixedly connected to the side of the rocker arm 18 near the movable block 17. A bidirectional screw 21 is movably connected to the inside of the connecting frame 16 through a bearing. Both sides of the surface of the bidirectional screw 21 are threaded with a sleeve 22. A push rod 23 located inside the fork 20 is fixedly connected to the back of the sleeve 22. The push rod 23 and the fork 20 are slidably connected.

[0052] As a technical optimization of this utility model, the two-way screw 21 drives the two-sided screw sleeves 22 to move in opposite directions, and the push rod 23 pushes the shift fork 20 to realize the symmetrical opening and closing of the pawl.

[0053] refer to Figure 4 The connecting frame 16 is internally fixedly connected to a limiting strip 24, which is located at the bottom of the screw sleeve 22. The screw sleeve 22 and the limiting strip 24 are slidably connected.

[0054] As a technical optimization of this utility model, the limiting strip 24 constrains the screw sleeve 22 to move only in a straight line, preventing lateral displacement when the bidirectional screw 21 rotates, reducing wear between the screw and the screw sleeve 22, and improving the durability of the adjustment mechanism.

[0055] refer to Figure 4 A motor 25 is fixedly connected to the left side of the connecting frame 16, and the output end of the motor 25 is fixedly connected to the left end of the bidirectional screw 21.

[0056] As a technical optimization of this utility model, the opening and closing of the gripper is electrically controlled by the motor 25, which can be adapted to different sizes of the inspection objects 3. At the same time, the driving method of the motor 25 can greatly improve the automation effect.

[0057] The working principle and usage process of this utility model are as follows: The test object 3 is placed on the top of the testing platform 1. The transmission motor 13 is started, driving the transmission rod 8 to rotate. Through the sliding cooperation between the slide rod 11 on the left side of the rotating wheel 9 and the sleeve plate 10, the shaft 5 is driven to rotate. The pressure plates 6 at both ends of the shaft 5 rotate to a horizontal position, pressing down and fixing the test object 3 to ensure its stability during the test. The pressure component 2 descends vertically, applying pressure to the test object 3 for strength testing. During the test, the debris generated by the extrusion falls into the receiving frame 12 through the open opening at the top of the testing platform 1. Inside, as the transmission rod 8 rotates continuously, the conveying blade 14 fixed on the surface rotates synchronously, pushing the debris in the receiving frame 12 along the inner wall to the discharge port 15 on the right side, realizing the automatic discharge of debris and keeping the detection environment clean. At the same time, the pressure plate 6 can be released when the rotating wheel 9 rotates half a turn each time. The pressure plate 6 is lifted and detached from the surface of the detection object 3. At this time, the cement block can be easily removed, solving the problem of jamming of the traditional limit box and improving the loading and unloading efficiency. When the pressure plate 6 completes the clamping and fixing, the motor 25 on the left side of the connecting frame 16 is started, driving the bidirectional screw 21 to rotate. Under the guidance of the limit bar 24, the screw sleeve 22 moves towards or away from each other, driving the push rod 23 to push the shift fork 20, causing the swing rod 18 to swing around the pin shaft. The shielding frame 19 at the end of the swing rod 18 adjusts its position accordingly, which not only protects the pressure assembly 2, but also assists in positioning, ensuring that the center of gravity of the pressure application is accurate. After the test is completed, all components are reset: the pressure plate 6 returns to the initial pressing angle, the conveyor blade 14 clears the debris, and the shielding frame 19 returns to the periphery of the pressure assembly 2. The system is ready and can proceed to the next round of testing.

[0058] In summary, this construction quality inspection device uses a pressure plate 6 that rotates via a shaft 5 to press and release the inspection object 3, avoiding the jamming problem of traditional limit boxes, significantly improving loading and unloading efficiency. Moreover, the pressing method is highly stable, preventing broken inspection objects 3 from tipping over and colliding.
