[0025] A flipping assembly is provided on the right side of the support frame 1. The flipping assembly includes a drive cylinder 6, a flipping platform 7, a connecting plate 4, and a positioning module. The drive cylinder 6 is tilted below the flipping platform 7. One end of the flipping platform 7 is hinged to the support frame 1 via a rotating shaft 16. The bottom of the drive cylinder 6 is fixedly installed on the support frame 1. The output end of the drive cylinder 6 is fixedly connected to the flipping platform 7. The drive cylinder 6 drives the flipping platform 7 to flip around the rotating shaft 16. The connecting plate 4 is installed on the flipping platform 7. The mold box 10 is placed on the connecting plate 4. The mold box is used to hold the cured concrete test blocks. The positioning module is installed on the connecting plate 4 and the flipping platform 7. The positioning module is used to limit the position of the mold box 10. A pneumatic demolding mechanism is installed on the connecting plate 4 below the mold box 10. The pneumatic demolding mechanism blows the concrete test blocks in the mold box 10 out of the mold box 10, so that the concrete test blocks fall onto the corresponding trays.

[0026] The mold box 10 can hold multiple concrete test blocks as needed; in this embodiment, nine (3×3) concrete test blocks are used as an example. The mold box 10 containing the cured concrete test blocks is transported by an AGV transport vehicle with a forklift lifting function. This AGV transport vehicle can transport the concrete test block pallet to the demolding area for demolding and can also allow different groups of demolded concrete test blocks to fall onto the pallet. The AGV transport vehicle is equipped with a lifting mechanism, which has an electric fork arm. The lifting mechanism drives the electric fork arm to rise to a designated height, and the electric fork arm is used to pick up the mold box 10. The AGV transport vehicle with the lifting mechanism and electric fork arm adopts an existing structure, which will not be described in detail here.

[0027] A detection element 12 is installed on the support frame 1. The detection element 12 is located between the clamping mechanism 17 and the mold box 10 after the flipping component flips upward by 90°. The detection element 12 is used to detect and determine whether the concrete test block has been removed from the mold box 10 and onto the tray.

[0028] The clamping mechanism 17 includes a horizontally arranged clamping top rod 20, and an upper test block baffle 2 and a lower test block baffle 3 fixedly installed on the upper and lower sides of the clamping top rod 20 in a longitudinal direction. The lower test block baffle 3 is fixedly installed at the output end of the clamping cylinder 9. The upper test block baffle 2 and the lower test block baffle 3 are used to prevent the concrete test block from continuing to move after reaching the tray position when the concrete test block is demolded.

[0029] The positioning module includes positioning guide posts 5, positioning guide plates 11, and limiting posts 14. Two sets of positioning guide plates 11 are symmetrically installed at the left and right ends of the flipping platform 7.

[0030] The connecting plate 4 has guide post mounting holes 18 at both its front and rear ends, and the positioning guide post 5 is threaded into the guide post mounting holes 18. In this embodiment, the connecting plate 4 has two sets of positioning guide posts 5 at its front and rear ends, respectively. The two sets of positioning guide posts 5 are respectively located near the left and right ends of the connecting plate 4. On the one hand, this ensures that the positioning guide posts 5 limit and fix the mold box 10 in the front and rear direction on the connecting plate 4, and on the other hand, it facilitates the electric fork arm to pick up and put the mold box 10 between the two sets of positioning guide posts 5.

[0031] Multiple sets of limiting posts 14 are evenly distributed on the upper surface of the connecting plate 4. The limiting posts 14 are used to provide longitudinal support and limit the mold box 10.

[0032] The pneumatic demolding mechanism includes an air blowing element 13, which is fixedly installed on the connecting plate 4. The number and position of the air blowing element 13 correspond to the number and position of the concrete test blocks in the mold box. The bottom of the mold box 10 is provided with an air hole that cooperates with the air blowing element 13. The air blowing element 13 performs pneumatic demolding of the concrete test blocks in the mold box 10 through the through hole. A sealing ring 19 is connected between the air blowing element 13 and the air hole.

[0033] The air blowing element 13 is cylindrical, with an air channel running vertically through the center of the cylinder. An end-face sealing groove is formed on the upper surface of the cylinder, and a radial sealing groove is formed on the circumferential surface of the cylinder. O-rings 19 are installed in both the end-face sealing groove and the radial sealing groove to ensure that the air blowing element 13 is completely sealed to the mold box 10 when the concrete specimen is demolded, and that there is sufficient pressure to ensure successful demolding. The lower end of the cylinder is machined with external threads for fixing and mounting on the connecting plate.

[0034] Air blowing elements 13 and limiting posts 14 are evenly and alternately installed in the central area of ​​the connecting plate to achieve accurate positioning of the air holes of the mold box 10 and the air blowing elements 13, as well as the demolding of the test block.

[0035] The working principle of this utility model is as follows:

[0036] The AGV transport trolley transports the mold box 10 containing the cured concrete test blocks to the designated position in front of the flipping assembly. The lifting mechanism on the AGV transport trolley is activated, raising the mold box 10 containing the concrete test blocks to the designated height. The lifting mechanism stops, and the electric fork arm installed on the lifting mechanism starts working, extending the mold box 10 containing the concrete test blocks forward to above the flipping platform 7. The lifting mechanism is activated, lowering the mold box 10 containing the concrete test blocks. During the descent, the mold box 10 descends to the corresponding position on the connecting plate 4 under the action of the positioning module, ensuring that the air blowing element 13 matches the air hole on the bottom surface of the mold box 10 for sealing.

[0037] The driving cylinder 6 of the flipping component drives the flipping platform 7 to flip, so that the mold box 10 containing the concrete test blocks slowly flips 90° counterclockwise. The flipped mold box 10 contains the first group, the second group, and the third group of test blocks from top to bottom.

[0038] The clamping mechanism 17 is connected to the front end of the clamping cylinder 9, and the rear end of the clamping cylinder 9 is connected to the slider of the lifting cylinder 8. The clamping cylinder 9 pushes the clamping mechanism 17 forward. At this time, the clamping top rod 20 of the clamping mechanism 17 presses down on the second set of test blocks. The AGV trolley carrying the pallet arrives at the designated position between the clamping component and the flipping component and waits. The lifting mechanism of the AGV trolley starts and lifts the pallet to the height position between the clamping top rod 20 and the bottom of the first set of test blocks. The lifting mechanism stops, and the electric fork arm installed on the lifting mechanism starts to work and extends the pallet to the bottom position of the first set of test blocks. At this time, the pneumatic demolding mechanism air blowing element 13 corresponding to the first set of test blocks removes the first set of test blocks onto the pallet. The upper test block baffle 2 prevents the concrete test blocks from continuing to move in the removal direction. The detection element 12 detects the removal of the test blocks. After all the first set of test blocks are removed, the AGV trolley transfers the pallet carrying the first set of test blocks to the designated position.

[0039] Keep the clamping rod 20 pressing down on the second set of test blocks. Demold the third set of test blocks in the same way. The lifting mechanism and electric fork arm of the AGV trolley work together to extend the pallet to the bottom position of the third set of test blocks. At this time, the air blowing element 13 of the pneumatic demolding mechanism corresponding to the third set of test blocks will remove the third set of test blocks onto the pallet. The lower test block baffle 3 will prevent the concrete test blocks from moving further in the demolding direction. The detection element 12 will detect the demolding status of the test blocks. After all the third set of test blocks have been demolded, the AGV trolley will transfer the pallet carrying the third set of test blocks to the designated position.

[0040] The clamping cylinder 9 pulls the clamping mechanism 17 to retract, the lifting cylinder 8 begins to rise, and the clamping cylinder 9 pushes the clamping mechanism 17 forward. At this time, the clamping rod 20 of the clamping mechanism 17 presses on the first set of test blocks. The lifting mechanism of the AGV trolley and the electric fork arm work together to extend the pallet to the bottom position of the second set of test blocks. At this time, the pneumatic demolding mechanism air blowing element 13 corresponding to the second set of test blocks removes the second set of test blocks onto the pallet. The lower test block baffle 3 prevents the concrete test blocks from continuing to move in the demolding direction. The detection element 12 detects the demolding status of the test blocks. After all the second set of test blocks are removed, the AGV trolley transports the pallet carrying the second set of test blocks to the designated position. At this point, all the concrete test blocks in the mold box 10 have been demolded.

[0041] The clamping component returns to its original position, and the driving cylinder 6 of the flipping component drives the flipping platform 7 to flip, so that the empty mold box 10 slowly flips 90° clockwise to return to its original position. The empty mold box 10 is then transferred to the designated location by the AGV trolley.

Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention.
