In addition, embodiments of the present application and features of the embodiments may be combined with each other without conflict. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model, and the described embodiments are merely some, rather than all, embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present utility model without making any inventive effort, are intended to fall within the scope of the present utility model.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model.

As shown in fig. 1-2, the present solution specifically discloses a reinforcement device for the problem of cracking of a gantry of a stacking machine, firstly, the structure of the stacking gantry 1 needs to be known, the stacking gantry 1 is installed on a special vehicle, three groups of cross bars 2 are sequentially arranged on the stacking gantry 1 from bottom to top, each group of cross bars 2 faces one side of the special vehicle, meanwhile, the cross bars 2 need to be fixed on the stacking gantry 1, so that welding fixation needs to be performed on two sides of the stacking gantry 1 and two ends of the cross bars 2 through connecting blocks 3, in order to ensure the stability of the connecting blocks 3, the connecting blocks 3 are arranged to be approximately triangular, wherein two groups of end angles of the connecting blocks 3 are fixedly connected with the stacking gantry 1, and the remaining end angles of the connecting blocks are outwards connected with the cross bars 2, so that the connecting blocks of the cross bars 2 and the stacking gantry 1 are completed. When the fork lift truck works, the telescopic rod is stretched out on the special vehicle to be buckled on the cross rod 2, the telescopic rod is controlled to stretch to drive the fork lift truck 1 to swing back and forth, the fork lift truck 1 is switched between vertical and inclined, and the process of stacking objects is achieved.

However, in this process, since the stacking mast 1 needs to be switched back and forth between the upright and inclined states, the local pressure of the stacking mast 1 is constantly changed, thereby increasing the risk of breakage of the stacking mast 1. Therefore, the reinforcing members 4 for tightly supporting and reinforcing are required to be arranged on two sides of the connecting block, wherein the reinforcing members 4 comprise a fixing part 40, a tightly supporting part 41 and a supporting part 42, the tightly supporting part 41 and the supporting part 42 are respectively arranged on two groups of sides of the fixing part 40, and the tightly supporting part 41 and the supporting part 42 are distributed in an included angle, in this state, the fixing part 40 is welded on the stacking portal 1, the supporting part 42 extends to the connecting part of the connecting block 3 and the cross rod 2, and the welding is performed after tightly supporting the edge of the connecting block 3, so that the whole width of the connecting block 3 is increased, the whole strength of the connecting block 3 is improved, and meanwhile, the transverse stress born by the connecting block 3 is transmitted to the supporting part 42 through the support of the supporting part 42, so that the stress of the connecting block 3 is reduced. The direction of the propping part 41 is parallel to the height direction of the portal of the stacker, then the propping part 41 is welded on the stacker portal 1, and the pressure born by the supporting part 42 can be shared to other parts of the stacker portal 1 through the propping part 41, so that the pressure bearing area between the connecting block 3 and the stacker portal 1 is reduced, the local pressure is reduced, and the occurrence of fracture caused by local pressure of the stacker portal 1 is reduced.

Further, because the positions of the three groups of cross bars 2 on the stacking portal frame 1 are different, the moment between the three groups of cross bars 2 and the special vehicle is also different, and the pressures born by the three groups of connecting blocks 3 are also different, different reinforcing pieces 4 are required to be arranged according to different positions, as shown in fig. 3-5, the reinforcing pieces comprise a first reinforcing piece 4a, a second reinforcing piece 4b and a third reinforcing piece 4c, and the three groups of connecting blocks 3 are sequentially a first connecting block 30, a second connecting block 31 and a third connecting block 32 from bottom to top; the lower part of the first connecting block 30 is tightly supported and fixed by the first reinforcing piece 4a, and the upper part of the first connecting block 30 is tightly supported and fixed by the second reinforcing piece 4 b; the second reinforcement 4b is tightly propped and fixed below the second connecting block 31, and the first reinforcement 4a is tightly propped and fixed above the second connecting block 31; the third connecting block 32 is held in place by the third reinforcing member 4c both above and below.

The length of the supporting portion 42 of the second reinforcement 4b is greater than the length of the supporting portion 42 of the first reinforcement 4a, the length of the tightening portion 41 of the second reinforcement 4b is smaller than the length of the tightening portion 41 of the first reinforcement 4a, and the tightening portions 41 of the two groups of second reinforcements 4b are tightened with each other. Because the first connecting block 30 and the second connecting block 31 are both located below the stacking portal 1, the distance between the two lower groups of cross bars 2 and the special vehicle is shorter, the moment is smaller, the pressure born by the two lower groups of cross bars 2 is also larger, and the support parts 42 of the longer second reinforcing members 4b are required to support and fix, and at the same time, the tightening parts 41 of the two groups of second reinforcing members 4b are mutually tightened, so that the force is transmitted to other places through the mutually tightened parts of the two groups of tightening parts 41, the stress area is increased, and the condition of stress concentration caused by the reinforcing defect is avoided.

Further, since the distance between the upper group of cross bars 2 and the special vehicle is generally relatively long, the third reinforcement 4c cannot disperse stress in such a manner that the tightening portions 41 of the two groups of second reinforcement 4b are tightened against each other, and thus the width of the tightening portions 41 of the third reinforcement 4c is larger than the length of the supporting portions 42 of the first reinforcement 4a and the length of the supporting portions 42 of the second reinforcement 4b, so that the third reinforcement 4c can disperse pressure to a larger area, and the stability of the third connection block 32 is improved.

Further, the notch 5 is arranged at the joint of the jacking part 41 and the supporting part 42, and the welding is performed between the notch 5 and the stacking portal 1, so that the welding area of the reinforcement and the stacking portal 1 is increased, and the stability between the reinforcement and the stacking portal 1 is improved.

The present utility model is not limited to the preferred embodiments, and any modifications, equivalent variations and modifications made to the above embodiments according to the technical principles of the present utility model are within the scope of the technical proposal of the present utility model.
