As shown in fig. 1 and 5, the gantry 2 has a frame structure, a connecting beam 18 is disposed in the middle, and a fork fixing frame 20 is mounted on the gantry 2 in a guiding manner along the up-down direction. As shown in fig. 7, the fork fixing frame 20 is also in a frame structure, and is internally connected with a cross beam 33 and a vertical beam 32 in a cross structure, and in order to improve the structural strength of the fork fixing frame 20, cross diagonal braces 34 are arranged in four boxes enclosed by the cross beam 33, the vertical beam 32 and the peripheral frame. The forks 3 are fixed to the lower portion of the middle portion of the vertical beam 32, and only one fork 3 in this embodiment is used for being directly inserted into the inner hole of the aluminum ring. In order to improve the structural strength of the pallet fork 3 and ensure the service life, reinforcing rib plates 4 are welded between the pallet fork 3 and the vertical beams 32, as shown in fig. 2.

In order to form good guiding effect to the fork mount 20, improve the life of fork mount 20, be provided with respectively at the left and right sides of fork mount 20 with portal 2 direction removal complex left guide structure and right guide structure, still be provided with and move complex back guide structure with portal 2 direction simultaneously in the rear side of fork mount 20.

Specifically, as shown in fig. 7 and 8, the left guide structure on the fork fixing frame 20 is a left guide plate 36, the right guide structure is a right guide plate 22, and correspondingly, as shown in fig. 6, two guide grooves 19 are arranged on the portal frame 2, the guide grooves 19 are in a U shape, and the left guide plate 36 and the right guide plate 22 are both cuboid shapes. As shown in fig. 8, the rear guide structure is two dovetail seats 21 fixed at the rear side of the pallet fork fixing frame 20, dovetail grooves are formed in the dovetail seats 21, and correspondingly, as shown in fig. 6, two dovetail protrusions 1 are arranged on the door frame 2.

On the basis of the coordination of the guide groove and the guide plate, the dovetail seat and the dovetail bulge are arranged to be matched, so that besides the guiding in the upper and lower directions is enhanced, the weight of the aluminum ring is mainly used for applying a forward rotating torque to the fork fixing frame after the aluminum ring is forked, the two U-shaped guide grooves 19 are oppositely arranged, and the torsion bearing capacity of the fork fixing frame can be improved by the combination of the two pairs of dovetail seats and the dovetail bulge. In addition, in order to ensure the torque capacity of the mast 2, reinforcing ribs 14 are welded between the mast 2 and the carriage 12, as shown in fig. 2 and 6.

As shown in fig. 1, three up-down driving mechanisms 5 for driving the fork fixing frame 20 to move up and down are arranged on the gantry 2 at intervals, the up-down driving mechanisms 5 can be specifically hydraulic cylinders, air cylinders or electric push rods, the fixed ends of the up-down driving mechanisms 5 are fixed on the gantry 2, the telescopic ends are connected with the fork fixing frame 20, and when the up-down driving mechanisms 5 act, the up-down driving mechanisms can drive the fork fixing frame 20 to move up and down, so as to drive the fork 3 to move up and down.

In addition, as shown in fig. 1 and 10, two supporting blocks 23 are further disposed on the frame 35, and a jacking device 7 is disposed on top of each supporting block 23, where the jacking device 7 may be a hydraulic cylinder, an air cylinder or an electric push rod. The fixed end of the bottom of the jacking device 7 is fixed on the supporting block 7, the telescopic end at the top is hinged with the supporting plate 6, and the supporting plate 6 is an arc-shaped plate. After the aluminium circle is got to fork 3 fork, thereby rise through jacking device 7 control backup pad 6, thereby backup pad 6 self-adaptation rotate paste with the surface of aluminium circle mutually, supplementary fork 3 is fixed and is supported the bottom of aluminium circle, and arc design has guaranteed area of contact ratio great, and the supporting effect is better.

In addition, it should be noted that, in this embodiment, the protruding portion of the sliding seat 12 is provided with a boss to be matched with the guide rail, and the remaining portion is provided with a roller bearing to be matched with the guide rail, which is because after the fork picks up the goods, the front side of the whole portal is stressed greatly, the goods can press the portal and the sliding seat to make the portal and the sliding seat rotate forward, at this time, due to the existence of the assembly gap, the roller bearing on the remaining portion can push up against the guide rail, and a tiny gap is generated between the boss on the protruding portion and the guide rail, so that the friction force of the sliding seat in the moving process is smaller due to the roller bearing tightly pushing against the guide rail, which not only ensures the smoothness of the movement, but also can save the configuration cost of the roller bearing.

The working principle of the transferring and stacking system in the utility model is as follows:

after the aluminum ring 24 is produced in the pit 28, the aluminum ring is supported by the pit supporting device 27 and ascends to expose the pit, the transferring and stacking vehicle is instructed to automatically move to the position of the pit 28, the pit supporting device 27 is controlled to enable the guide rail 26 on the pit supporting device to be equal to the guide rail 11 on the transferring and stacking vehicle in height, then the sliding seat 12 is pushed to move forwards through the front-back driving mechanism 16, the gantry 2, the fork fixing frame 20 and the fork 3 are driven to move forwards, the sliding seat 12 slowly extends out of the guide rail 11, and the extending part of the sliding seat 12 extending out of the guide rail 11 is supported and matched with the guide rail 26 on the pit supporting device 27 in a guiding and moving mode, so that the gantry 2, the fork fixing frame 20 and the fork 3 are jointly supported together with the reserved part. Because three guide rails 11 on the transfer stacker car correspond to three guide rails 26 on the pit supporting device 27 one by one, the fork 3 can gradually extend into the inner hole of the aluminum ring 24 in the forward moving process, after the fork 3 reaches a proper position, the front-back driving mechanism 16 is controlled to stop running, and then the upper-lower driving mechanism 5 is started, so that the fork fixing frame 20 and the fork 3 move upwards to fork the aluminum ring 24, and at the moment, due to the joint supporting effect of the extending part and the retaining part, a stable support can be formed for the door frame 2, the door frame 2 is prevented from bearing excessive torque, the balance and the stability of the transfer stacker car are improved, and the safety of the aluminum ring 24 and surrounding operators is further ensured.

The front and rear drive mechanism 16 is then activated to move the fork 3 back along with the aluminium ring, in which process the collective support of the extension and the retention initially ensures the stability of the whole transfer stacker, and subsequently the majority of the carriage is retracted onto the rail 11, ensuring stability even if disengaged from the rail 26. After the slide resets, the upper and lower actuating mechanism of control resets, and fork mount and fork all move initial position down, then rise through jacking device 7 control backup pad 6 to the rotation of backup pad 6 self-adaptation pastes with the surface of aluminium circle mutually to supplementary fork 3 holds the bottom of aluminium circle, guarantees the stability of aluminium circle in the transportation, avoids the fork to bear too big moment of torsion simultaneously.

Then the transporting and stacking vehicle automatically moves to the position of the goods shelf, the fork is firstly moved upwards by the up-down driving mechanism, then the sliding seat, the door frame and the fork are controlled by the front-back driving mechanism to move forwards, the extending part of the sliding seat is supported by the guide rail 30 on the goods shelf and is matched with the guide movement, when the aluminum ring is stacked on the goods shelf, the door frame, the fork fixing frame, the fork and the aluminum ring are also supported by the extending part and the retaining part together, and further the balance and the stability of the transporting and stacking vehicle are ensured. When the aluminum ring moves above the support frame 29, the fork is moved downward by the up-down driving mechanism, and the aluminum ring is placed on the support frame 29.
