Support component described in every group includes supporting plate 8, and the section of the supporting plate 8 is L-type, and the structural strength in order to guarantee supporting plate 8, institute
It is provided with reinforcing rib 8-1 between two end faces of the supporting plate 8 stated, should pay attention to avoiding reinforcing rib 8-1 when reinforcing rib 8-1 is arranged
The placement that is larger and interfering casting being arranged.One end of supporting plate 8 is hinged on the middle part of layering bar 3 by sleeve 9, at supporting plate 8
When support casting state, the free end of the supporting plate 8 on two layering bars 3 is in the state of opposite direction；The driving group
Part includes the sequentially connected rack gear 6 of several sections, and the joint number of rack gear 6 is corresponding with the quantity of supporting plate 8, one end of the rack gear 6
It is provided with connecting hole, the other end of rack gear 6 is provided with connecting shaft 7, and the connecting shaft 7 of rack gear 6 is slideably inserted into the company of adjacent rack 6
It connects in hole, the rack gear 6 slides through corresponding layering bar 3, and the outer surface of the sleeve 9 is provided with opposite with rack gear 6
The gear 10 answered, is provided with window 3-1 on the medial surface of square pipe at supporting plate 8, the rack gear 6 slide vertically across
Square pipe, the gear 10 on the sleeve 9 pass through window 3-1 and engage connection with rack gear 6.It is not placed when rack 1 is in
When the state of casting, certain spacing is reserved between adjacent rack 6.
As shown in Fig. 2, being provided with support frame 4 on the downside of each column described in the present embodiment, the support frame 4 is wrapped
It includes fixed frame 4-1 and supporting leg 4-4, the fixed frame 4-1 is fixedly welded on the bottom of column, and the length side of fixed frame 4-1
To the length direction perpendicular to column, fixed frame 4-1 is hinged on fixed frame 4- towards the inside of rack 1, one end of supporting leg 4-4
On 1, and it is provided with connecting hole on supporting leg 4-4, the first limit hole 4-2 and the second limit hole 4-3 are provided on fixed frame 4-1, props up
Through there is limit pin shaft between one of limit hole on connecting hole on leg 4-4 and fixed frame 4-1, when on supporting leg 4-4
When connecting hole is aligned with the first limit hole 4-2 on fixed frame 4-1, the length direction of the supporting leg 4-4 is perpendicular to fixed frame
The length direction of 4-1, when the connecting hole on supporting leg 4-4 is aligned with the second limit hole 4-3 on fixed frame 4-1, supporting leg 4-4's
Length direction is perpendicular to the length direction of fixed frame 4-1, and supporting leg 4-4 is directed downward, and the bottom end of the locking universal wheel 5 is higher than
The bottom of supporting leg 4-4.The purpose that support frame 4 is arranged mainly is convenient for conversion of the transfer car(buggy) in usage scenario, in workshop
When portion shifts, supporting leg 4-4 is packed up, rack 1 is supported by locking universal wheel 5, in cross-region transfer, is needed rack
1 is placed on transport vehicle, and supporting leg 4-4 is unfolded, and supports rack 1 by support frame 4, can be avoided the lock of locking universal wheel 5
Failure and caused by rack 1 arbitrarily shake.
Working principle: as shown in figure 3, when not placing casting, due to the gravity of rack gear 6, two equal directions of supporting plate 8
Outside, defining the state is to deflect 0 ° of state, and supporting plate 8 can limit supporting plate 8 after contact is layered bar 3 and continue to rotate, and be
Avoid rack gear 6 that supporting plate 8 is interfered to rotate, the free end of the supporting plate 8 is provided with the recess for accommodating rack gear 6；Such as Fig. 4 institute
Show, when placing casting 11, the two sides of casting 11 are pressed respectively against on two supporting plates 8, and for two supporting plates 8 towards inside, definition should
State is the state of 180 ° of deflection, and supporting plate 8 can limit supporting plate 8 after contact is layered bar 3 and continue to rotate, therefore supporting plate 8
Slewing area is 180 °.
It is waited and so on as shown in fig. 7, defining rack 1 and being followed successively by first layer, the second layer, third layer from bottom to top,
Before placing casting 11 into rack 1, first the supporting plate of first layer 8 is adjusted to the state towards inside, and in the mistake of adjustment
Cheng Zhong, for the ease of placing casting, which can be arranged due to being provided with certain spacing distance between adjacent rack 6
For gear 10 rotate 90 ° when rack gear 6 moving distance, therefore the bracket 8 of first layer rotate 90 ° when, adjacent rack 6 it
Between it is unaffected, adjacent pallets 8 do not act, and when placing casting 11, the supporting plate 8 that casting 11 presses first layer is continued to rotate
When, adjacent rack 6 directly contacts, and the jacking of the rack gear 6 upside rack gear 6 positioned at downside, the rack gear 6 positioned at upside passes through 10 band of gear
The supporting plate 8 of the dynamic second layer rotates 90 degree.Continue to place casting 11 in the second layer, since supporting plate 8 has been in the shape of 90 ° of deviation
State no longer needs to stir supporting plate 8 with hand, and 8 turns of supporting plate that pushing side is deviateed in the side Shi Xianxiang need to be only placed by adjusting casting 11
It is dynamic, then deviate to the other side and press the rotation of other side supporting plate 8, it will finally be placed in the tune of casting 11.In order to avoid placing
First layer needs the supporting plate 8 with the whole first layer of hand adjustment, the downside of rack 1 can be provided with limit plate, and limit plate is located at the
The downside of one layer of supporting plate 8, when not placing casting 11, the lower end of rack gear 6 corresponding with the supporting plate 8 of first layer is against limit plate
On, so that supporting plate 8 is maintained at the state of 90 ° of deflection, it is just identical as upper several layers of modes of emplacement when first layer places casting 11 in this way.
And when unloading casting 11, once casting 11 is taken out since one layer most upper, after taking out casting 11, on supporting plate 8
No longer there is pressure, supporting plate 8 is pressed by the gravity of rack gear 6 and is rotated backward to 90 ° of deflection of state, when next layer gradually unload
When after load, the supporting plate 8 of this layer, which just will continue to be turned to by the gravity drive of rack gear 6, to be fitted on layering bar 3, and supporting plate 8 is in
Towards the state in outside.
Above-mentioned specific embodiment is only specific case of the invention, and scope of patent protection of the invention includes but is not limited to
The product form and style of above-mentioned specific embodiment, any claims of the present invention and any technical field of meeting
The appropriate changes or modifications that those of ordinary skill does it, all shall fall within the protection scope of the present invention.
