Step 3: gradually bring the interface between the second curved plate and the first curved plate closer to each other;

Step 4: While pressing the pulling plate, the staff needs to position the spherical rod on the inner wall of the slot.

The present invention has the following beneficial effects:

According to the present invention, the staff connects the two delivery pump pipes, and the connection interface is set at the inner wall of the protective ring shell, and then presses the pulling plate, and the pulling plate drives the linkage frame to rotate, and one end of the linkage frame drives the second arc plate to rotate, and the other end of the linkage frame drives the square ring frame to rotate, and the square ring frame drives the first arc plate to rotate, so that the interface between the second arc plate and the first arc plate gradually approaches, and the second arc plate and the first arc plate approach each other, so as to clamp the annular bag, and the annular bag is deformed during the clamping process, so as to seal the connection between the two delivery pump pipes to prevent the concrete from being transported. Leakage occurs, and at the same time, the mutual proximity of the second arc plate and the first arc plate can improve the stability of the docking of the two delivery pump pipes, prevent the two delivery pump pipes from falling off during transportation, and improve the stability of transportation. In the process of pressing the pulling plate, the staff can clamp the spherical rod on the inner wall of the groove. When the impact force is too large during concrete transportation, the concrete will cause the two delivery pump pipes to move slightly away. At this time, the setting of the protective ring shell can prevent the concrete from being discharged outward. By docking and disassembling the spherical rod and the groove, the device can be easily and quickly disassembled.

(2) According to the present invention, when the two delivery pump pipes are slightly separated from each other, the delivery pump pipe drives the first fixed ring to move, the first fixed ring drives the first rotating plate to move, the first rotating plate drives the fixed block to move, and is limited by the square ring frame. The fixed block drives the spherical rod to slide along the inner wall of the slot. During the sliding of the spherical rod, the spherical rod drives the pulling plate to fall, and the spherical rod drives the fixed block to fall. During the falling of the fixed block, it will contact the square plate, and the fixed block causes the square plate to fall. The square plate drives the second rotating plate to fall. Limited by the arc groove, the second rotating plate drives the sliding block to slide along the inner wall of the arc groove. During the movement of the sliding block on the right side, the sliding block approaches one end of the arc groove, the sliding block drives the fixed rod to move, the fixed rod drives the special-shaped frame to move, and the special-shaped frame drives the rotating roller to move. During the movement of the rotating roller, the linkage frame can be squeezed to make the linkage frame approach one side of the pulling plate, thereby improving the clamping force between the pulling plate and the first arc plate, and further improving the stability of the two delivery pump pipes.

(3) In the present invention, when the two sliding blocks move away from each other, the sliding blocks drive the connecting blocks to move, and the connecting blocks drive the third rotating plate to move. The two third rotating plates move away from each other and drive the sliding plates to move. During the movement of the sliding plates, the sliding plates will come into contact with the second fixed ring to resist the movement of the second fixed ring, thereby preventing the delivery pump pipe from driving the second fixed ring to move excessively when the impact force is too large, causing the delivered concrete to be discharged outward, thereby improving the stability of concrete delivery.

(4) In the present invention, when the sliding plate moves, the sliding plate will first come into contact with the round rod, squeeze the round rod, and move the round rod, and the round rod drives the annular plate to move. At this time, the two round rods are close to each other inside the protective ring shell. During the movement of the annular plate, the airflow inside the protective ring shell enters the inside of the circular tube, and the airflow enters the inside of the annular bag through the circular tube, causing the annular bag to expand. During the expansion of the annular bag, the sealing effect of the two delivery pump pipes when they are connected can be further improved to prevent concrete leakage.

Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time.

The second rotating plate 662 is rotatably connected to the square plate 661 at one end away from the sliding block 663, and an arc spring 665 is fixedly connected to one side of the sliding block 663. The purpose of this arrangement is to facilitate resetting. The end of the arc spring 665 away from the sliding block 663 is fixedly connected to one side of the inner wall of the arc groove 664. A fixed rod 666 passes through and is fixedly connected to one side of the right sliding block 663, and only one fixed rod 666 is provided.

One side of the outer wall of the rotating roller 668 is in contact with one side of the outer wall of the linkage frame 64.

Seven springs 683 are provided. One side of the inner cavity of the protective ring shell 2 is connected to a round tube 684. One end of the round tube 684 is connected to one side of the inner wall of the annular bag 3. The round rod 681 drives the annular plate 682 to move. At this time, the two round rods 681 approach each other inside the protective ring shell 2. During the movement of the annular plate 682, the airflow inside the protective ring shell 2 enters the inside of the round tube 684. The airflow enters the inside of the annular bag 3 through the round tube 684, causing the annular bag 3 to expand. During the expansion of the annular bag 3, the sealing effect of the two delivery pump pipes 1 when docking can be further improved to prevent concrete leakage.

A method for using a quick-release joint for a concrete delivery pump pipe comprises the following steps:

Step 1: The staff docks the two delivery pump pipes 1, and the docking interface is set on the inner wall of the protective ring shell 2, and then presses the pulling plate 63, and the pulling plate 63 drives the linkage frame 64 to rotate;

Step 2: One end of the linkage frame 64 drives the second arc plate 61 to rotate, the other end of the linkage frame 64 drives the square ring frame 62 to rotate, and the square ring frame 62 drives the first arc plate 5 to rotate;

Step 3: gradually bring the interface between the second curved plate 61 and the first curved plate 5 closer to each other;

Step 4: During the process of pressing the pulling plate 63 , the staff needs to lock the spherical rod 652 into place on the inner wall of the locking groove 651 .

When in use, the staff docks the two delivery pump pipes 1, and the docking interface is set at the inner wall of the protective ring shell 2, and then presses the pulling plate 63, and the pulling plate 63 drives the linkage frame 64 to rotate, and one end of the linkage frame 64 drives the second arc plate 61 to rotate, and the other end of the linkage frame 64 drives the square ring frame 62 to rotate, and the square ring frame 62 drives the first arc plate 5 to rotate, so that the interface between the second arc plate 61 and the first arc plate 5 gradually approaches, and the second arc plate 61 and the first arc plate 5 approach each other, so as to clamp the annular bag 3, and the annular bag 3 is deformed during the clamping process, so as to seal the docking of the two delivery pump pipes 1 to prevent excessive delivery of concrete. Leakage occurs during the transportation process. At the same time, the second arc plate 61 is close to the first arc plate 5, which can improve the stability of the docking of the two delivery pump pipes 1 and prevent the two delivery pump pipes 1 from falling off during transportation, thereby improving the stability of transportation. In the process of pressing the pulling plate 63, the staff can clamp the spherical rod 652 on the inner wall of the slot 651. When the impact force is too large during the concrete transportation process, the concrete will cause the two delivery pump pipes 1 to slightly move away from each other. At this time, the protective ring shell 2 can prevent the concrete from being discharged outward. By docking and disassembling the spherical rod 652 and the slot 651, the device can be easily and quickly disassembled.

When the two delivery pump pipes 1 are slightly separated from each other, the delivery pump pipe 1 drives the first fixed ring 655 to move, the first fixed ring 655 drives the first rotating plate 654 to move, the first rotating plate 654 drives the fixed block 653 to move, and is limited by the square ring frame 62. The fixed block 653 drives the spherical rod 652 to slide along the inner wall of the slot 651. During the sliding of the spherical rod 652, the spherical rod 652 drives the pulling plate 63 to fall, and the spherical rod 652 drives the fixed block 653 to fall. During the falling process of the fixed block 653, it will contact the square plate 661, and the fixed block 653 causes the square plate 661 to fall, and the square plate 661 drives the second rotating plate 66 2 falls, and is limited by the arc groove 664. The second rotating plate 662 drives the sliding block 663 to slide along the inner wall of the arc groove 664. During the movement of the sliding block 663 on the right side, the sliding block 663 approaches one end of the arc groove 664, and the sliding block 663 drives the fixed rod 666 to move. The fixed rod 666 drives the special-shaped frame 667 to move. The special-shaped frame 667 drives the rotating roller 668 to move. During the movement of the rotating roller 668, the linkage frame 64 can be squeezed to make the linkage frame 64 approach one side of the pulling plate 63, thereby improving the clamping force between the pulling plate 63 and the first arc plate 5, and further improving the stability of the two delivery pump pipes 1.

When the two sliding blocks 663 move away from each other, the sliding block 663 drives the connecting block 671 to move, and the connecting block 671 drives the third rotating plate 672 to move. The two third rotating plates 672 move away from each other and drive the sliding plate 673 to move. During the movement of the sliding plate 673, it will come into contact with the second fixed ring 674 to resist the movement of the second fixed ring 674 to prevent the delivery pump pipe 1 from driving the second fixed ring 674 to move excessively when the impact force is too large, causing the delivered concrete to be discharged outward, thereby improving the stability of concrete delivery.

When the sliding plate 673 moves, the sliding plate 673 will first come into contact with the round rod 681, squeeze the round rod 681, and move the round rod 681, and the round rod 681 drives the annular plate 682 to move. At this time, the two round rods 681 approach each other inside the protective ring shell 2. During the movement of the annular plate 682, the airflow inside the protective ring shell 2 enters the inside of the circular tube 684, and the airflow enters the inside of the annular bag 3 through the circular tube 684, causing the annular bag 3 to expand. During the expansion of the annular bag 3, the sealing effect of the two conveying pump pipes 1 when docking can be further improved to prevent concrete leakage.
