The driving motor 9 The screw 82 is driven to rotate through the transmission structure, and a pushing assembly 10 is also provided on the outside of the receiving box 1. Since the driving block 81 and the screw 82 are a nut-screw structure, the screw 82 will drive the driving block 81 to move along the screw 82 during its rotation, thereby realizing the extension and retraction movement of the support plate 8 relative to the receiving box 1.

[0035] Preferably, the driving motor 9 is a servo motor, which has high precision and simpler program control.

[0036] Preferably, if Figure 1 and Figure 2As shown, the pushing assembly includes a guide rod 3, a push plate 5 and a driving cylinder 2. A fixed plate 11 is vertically provided on the side of the receiving box 1. The guide rod 3 is vertically passed through the fixed plate 11 and the two are relatively slidably connected. The axis of the guide rod 3 is parallel to the longitudinal center plane of the receiving box 1. The driving cylinder 2 is vertically fixed on the fixed plate 11. The output shaft of the driving cylinder 2 passes through the fixed plate 11 and is hinged to the lower end of the push plate 5. A guide frame 4 is provided at the end of the guide rod 3 close to the push plate 5. A guide shaft 41 is provided on the guide frame 4. A vertically arranged guide groove 51 is provided in the middle of the push plate 5. The guide shaft 41 is vertically arranged in the guide groove 51 and the two are slidably connected.

[0037] Preferably, when the output shaft of the driving cylinder 2 is in the extended state, the height of the guide bearing 54 is greater than the height of the receiving box 1, and the vertical distance between the guide bearing 54 and the fixed plate 11 is greater than the vertical distance between the end face of the receiving box 1 close to the guide bearing 54 and the fixed plate 11, thereby ensuring that the push plate 5 is lower than the receiving box 1 in the retracted state, making it convenient for the receiving box 1 to receive the steel pipe. When in the extended state, the push plate 5 protrudes out of the receiving box 1, thereby ensuring that all the steel pipes on the receiving box 1 are pushed off in time, thereby improving efficiency.

[0038] Preferably, the positioning protrusion 52, the positioning shaft 53 and the guide bearing 54 are matched and arranged in two sets, one set is arranged on the side of the upper end of the push plate 5 away from the driving cylinder 2, and the other set is arranged in the middle and upper part of the side of the push plate 5 away from the driving cylinder 2. The two sets are arranged so that force is applied to the upper end and the middle part at the same time to improve stability.

[0039] Preferably, the driving cylinder 2 is an oil cylinder or a gas cylinder, which is selected and set according to the weight of the steel pipe.

After the induction switch 7 senses the induction block 31, the signal can be taken and transmitted, thereby ensuring the accuracy of the action, ensuring the accuracy of the placement, and ensuring that all the steel pipes on the receiving box 1 are pushed down.

[0042] Preferably, a Y-shaped joint 21 is provided at the output shaft end of the driving cylinder 2, a hinge shaft 22 is provided in the middle of the Y-shaped joint 21, and the lower end of the push plate 5 is hinged to the Y-shaped joint 21 through the hinge shaft 22.

[0044] In the actual operation process, this device is symmetrically arranged on both sides of the packaging mechanism, and can operate both ends of the steel pipe at the same time. During the packaging process of the lower steel pipe, the driving motor 9 moves, driving the support plate 8 to extend, and the upper steel pipe can continue to be loaded onto the support plate 8. After the packaging of the lower steel pipe is completed and transported, the driving cylinder 2 is actuated, and the output shaft of the driving cylinder 2 extends, and the push plate 5 is driven to move through the Y-type joint 21. After the push plate 5 is turned to a vertical state, it continues to move forward, and the guide bearing 54 pushes the steel pipe to fall to the position to be packaged, completing the pushing action of the steel pipe. After the action is completed, the lower steel pipe continues to pack, the output shaft of the driving cylinder 2 is retracted, and the push plate 5 is transformed from a vertical state to a state close to the horizontal state, and the height is lower than the height of the receiving box 1. After the pushing is completed, the support plate 8 extends to facilitate the loading of subsequent steel plates, so that the loading action of the steel pipe is uninterrupted, which greatly improves the work efficiency. In the process of extending and retracting the output shaft of the driving cylinder 2, the induction switch 7 can correspond to the position of the induction block 31 to ensure the accuracy of the action. The whole structure is simple, stable and reliable.
