But the stack pallet of placement of multiple layers sheet-like workpiece
Technical field
The utility model relates to a kind of stack pallet, but a kind of stack pallet of placement of multiple layers sheet-like workpiece particularly, be mainly used in the automobile body-in-white field that is welded, utilize this stack pallet simultaneously many sheet-like workpieces (body in white parts) to be transported to another station from a station.
Background technology
Often utilize waggon that the body in white workpiece is delivered to another zone from a zone at the automobile body-in-white workshop that is welded, because being sheet metal, makes body in white, its area is bigger, inconvenience during conveying, what have utilizes flat dolly to transmit or artificial the transmission, and artificial transmission efficiency is low, labour intensity is big, dolly transmits and can't layering place, and the single-piece transmission efficiency is not high, and many meetings of transmission produce collision mutually.
Summary of the invention
But the purpose of this utility model provide a kind of simple in structure, operate steadily, the stack pallet of each part did not bump against mutually when transmission efficiency height, many transmitted placement of multiple layers sheet-like workpiece, overcome the deficiencies in the prior art.
But the stack pallet of placement of multiple layers sheet-like workpiece of the present utility model, comprise vehicle frame, bottom surface at vehicle frame is equipped with road wheel, four jiaos of places vertically are fixedly connected with column respectively above the vehicle frame, the column lower side is connected with the lower carrier plate frame by lower rotary shaft, the below that is positioned at the lower carrier plate frame on the column is provided with a bayonet lock of retaining lower carrier plate frame, the top is provided with down backing pin, the retaining platform of following backing pin and lower carrier plate frame top matches, column be positioned at the lower carrier plate frame above by on rotating shaft be connected with at least one upper supporting plate frame, be positioned at upper supporting plate frame top on the column and be provided with backing pin, described column is symmetrical setting in twos, is being provided with vertical pilot bar on the vehicle frame between column.
But the stack pallet of placement of multiple layers sheet-like workpiece of the present utility model can transmit the body in white workpiece of many sheets simultaneously, keeps certain clearance between each part, does not contact mutually, and the transmission efficiency height is simple in structure, operates steadily.

The specific embodiment
Shown in Fig. 1,4: 1 is vehicle frame, is the shaped steel welding production.Place, two angles of a side is equipped with respectively with respect to vehicle frame 1 rotating bogie truck 5 below vehicle frame 1, establish rolling bearing between bogie truck 5 and the vehicle frame 1, by rotating shaft road wheel 4 is installed on the bogie truck 5 and forms the wheeled structure of multi-axis foot, can turn to by this road wheel when namely walking.Place, two angles of opposite side is equipped with fixed mount 16 respectively below vehicle frame 1, and fixed mount 16 also is equipped with road wheel 4 by rotating shaft, and 4 of the road wheels during walking on the fixed mount 16 are followed rolling.Be provided with wheel frame 3 in each road wheel 4 outside, wheel frame 3 is fixedly connected on bogie truck 5 or the fixed mount 16 by side plate 2, and walking hour wheel frame 3 just built on stilts also can prevent that road wheel 4 is rolled on other objects.
Four jiaos of places vertically are fixedly connected with column 13 respectively above the vehicle frame 1, column 13 lower side are connected with lower carrier plate frame 8 by lower rotary shaft 15, the below that is positioned at lower carrier plate frame 8 on the column 13 is provided with a bayonet lock 7 of retaining lower carrier plate frame 8, the top is provided with down backing pin 14, and following backing pin 14 matches with the retaining platform 18 of lower carrier plate frame 8 tops.
Column 13 be positioned at lower carrier plate frame 8 above by on rotating shaft 10 be connected with at least one upper supporting plate frame 9, be positioned at upper supporting plate frame 9 tops on the column 13 and be provided with backing pin 11.
Inboard one end of lower carrier plate frame 8 and upper supporting plate frame 9 has bearing surface 19, and it is tip-tilted hook-shaped that the other end is.
Each upper supporting plate frame 9 of back is installed owing to there are last backing pin 11 retainings to lean on, all with respect to column 13 certain angle of inclination is arranged.Lower carrier plate frame 8 makes it deflection certain angle to the inside owing to there is bayonet lock 7 to exist, and is namely different with the upper supporting plate frame 9 residing angles of top.
Column 13 is symmetrical setting in twos, is being fixedly connected with vertical pilot bar 12 on the vehicle frame 1 between column 13.
As Fig. 2, shown in 3: utilize hoisting mechanism that sheet body in white workpiece 17 is from up to down placed, make workpiece 17 descending by four pilot bars, 12 guiding, inboard one end of each grillage 9 of top is all tilted upward, have only lower carrier plate frame 8 inboard ends of below to be in the state that inwardly stretches out, workpiece 17 just is placed on the bearing surface 19 of lower carrier plate frame 8, namely supported by four lower carrier plate framves 8, after lower carrier plate frame 8 is stressed, certain rotation inwardly takes place, rotate the back and be stuck in down location on the backing pin 14 by retaining platform 18, the outer end of lower carrier plate frame 8 upwarps partly and collides with the upper supporting plate frame 9 of its top simultaneously, make upper supporting plate frame 9 certain angle that turns to the inside, an inboard end inwardly has certain stretching out simultaneously, go up backing pin 11 after rotating and block upper supporting plate frame 9, and then second workpiece 17 hung in, make on its termination of dropping on upper supporting plate frame 9 inboards, by that analogy, every layer of upper supporting plate frame all can support a workpiece.But the stack pallet of placement of multiple layers sheet-like workpiece of the present utility model can transmit the body in white workpiece of many sheets simultaneously, keeps certain clearance between each part, does not contact mutually, and the transmission efficiency height is simple in structure, operates steadily.
