Description

Technical Field

[0001] The utility model relates to the technical field of lifting mechanisms, in particular to a double-station lifting mechanism for aluminum alloy bars. Background Art

[0002] After being heated, the aluminum alloy bars are transported to the elevator through a conveying mechanism, and the heated bars are lifted to the extruder by the elevator, and then extruded through the extruder.

[0003] However, the traditional elevator lifts the rods and then transports them to the extruder. Due to the wear caused by transporting the rods, the guide rollers on the elevator become horizontally unstable, causing the rods to have greater friction on the guide roller surface during transportation, which in turn requires the guide rollers to be replaced. The traditional guide roller replacement operation steps are cumbersome, and the lifting ends of the elevator need to be disassembled before the guide rollers can be replaced, resulting in low replacement efficiency.

[0009] Furthermore, the fixing seat is fixedly connected to the upper end of the mobile platform by screws.

[0010] Furthermore, the guide roller is located in the middle of the movable platform.

[0011] Compared with the above-mentioned background technology, the present application provides a double-station lifting mechanism for aluminum alloy bars, which includes a lifting mechanism with very mature technology today, and a connecting mechanism and a spring as core components.

It is a double-station arrangement. The rod 5 is placed when the mobile platform 3 is in the lower position, and then transported to the extruder after being lifted by the mobile platform 3. The rod 5 is moved and transported by the rotation of the guide roller 6. The guide roller 6 is rotated by the drive mechanism 4, and the connecting mechanisms set at both ends of the guide roller 6 are detachably connected to the mobile platform 3. The guide roller 6 is placed on the mobile platform 3 through the connection of the connecting rod 8. The advantage of this design is that the guide roller 6 is subjected to gravity friction when transporting the rod 5 for a long time, which causes the guide roller 6 to need to be replaced. Compared with the traditional guide roller 6, this design can be easily disassembled, and the guide roller 6 can be replaced by disassembling the connecting mechanism; the above-mentioned driving mechanism 4 is an existing known technical mechanism, which drives each guide roller 6 to rotate by driving the transmission belt through the motor.

[0023] like Figure 3 As shown, a connecting seat 11 is fixed to the output end of the driving mechanism 4, and the connecting seat 11 is rotatably arranged with the mobile platform 3. A card slot 12 is opened on the inner side of the connecting seat 11, and a bolt 13 is passed through the connecting seat 11; specifically, the bolt 13 is removed so that the bolt 13 can be separated from the connection mechanism at both ends of the connecting rod 8, so that the connecting rod 8 and the guide roller 6 can be taken out and replaced.

[0024] like Figure 5 and Figure 6As shown, the connecting mechanism also includes: a fixing seat 15, a mounting groove 14 is opened on the side wall of the mobile platform 3, the fixing seat 15 is matched with the mounting groove 14, the inner side of the lower end of the fixing seat 15 is fixedly connected with a connecting bearing 16, the connecting bearing 16 is plugged and rotated with the end of the connecting rod 8, the other end of the connecting rod 8 is fixed with a baffle 9, the outer side of the baffle 9 is fixedly connected with a card block 10, the card block 10 is matched with the card slot 12, and the bolt 13 is set through the connecting seat 11 and the card block 10, and the inner side of the mobile platform 3 is opened.

The outer end of the baffle 9 fixes the block 10 to be engaged with the slot 12 and fixed by a bolt 13. When disassembly is required, after removing the bolt 13, the guide roller 6 and the connecting rod 8 are moved toward the slot 12. The other end of the connecting rod 8 is just out of the connection bearing 16, and can then be disassembled.

[0025] like Figure 4 As shown, springs 7 are fixedly connected to both ends of the guide roller 6, and the springs 7 at both ends are respectively set to resist the connecting bearing 16 and the baffle 9. When the guide roller 6 rotates, the springs 7 at both ends push the guide roller 6 so that the guide roller 6 is centered inside the mobile platform 3, so that the rod 5 can move forward stably during transportation and correspond to the guide of the front-end extruder without deviation, thereby improving the effect of stable transportation.
