Referring to fig. 1, the present embodiment provides a transportation tray 10 for transporting plate members 30, which includes a bottom frame 100 and at least one supporting frame 200.

The support bracket 200 is used to support the panel 30, and the underframe 100 is configured as a part of the vehicle body 22 or connected with the vehicle body 22;

the supporting frame 200 has a first state of keeping parallel to the bottom frame 100 and a second state of keeping a preset included angle with the bottom frame 100;

At present, the industry is greatly promoting building industrialization, building construction is promoted to be assembled from factory prefabrication to site, wherein in the existing assembly type building system, prefabricated components of 'laminated plates' are horizontally transported and placed after factory prefabrication production. Specifically, the laminated slabs are generally transported on a flat-bed transport vehicle 21, and after being transported to a construction site, the laminated slabs are unloaded by a crane, stacked on the site, or directly hoisted to a building.

By adopting the method, the transportation of the laminated slabs greatly depends on hoisting equipment when loading in a factory and unloading in a construction site, and a single-slab hoisting mode is adopted, so that the vehicles are in a waiting state for a long time, the great waste is brought to the hoisting equipment, 21 transport vehicles and operators, the cost of building products is finally improved, and the competitiveness is influenced.

Simultaneously, when a plurality of superimposed sheet overlap each other and keep flat, can not coincide completely between the monolithic superimposed sheet when placing with other superimposed sheets, have clearance and hole between the two. When transported, the specific weight of the superimposed sheets may press against the edges of these gaps, causing stress damage to the sheets; the large plan area construction of the composite slab also exacerbates this damage by wobbling during transport.

By the scheme, the support frame 200 is kept in the first state during loading, so that horizontal loading is facilitated; when transporting, adjust the support frame 200 to the second state for the superimposed sheet can be transported about the vertical state, thereby avoiding the damage of the superimposed sheet. The transportation mode can fully save space waste in the transportation process, guarantee the transportation efficiency and improve the economic benefit.

Alternatively, in this embodiment, the driving device 400 is a winch, and the connecting device 510 is a cable (e.g., a steel cable). The support frame 200 can be turned and rotated by winding or loosening the steel rope through the winch, so that the first state and the second state are switched.

It should be noted that, in other embodiments of the present invention, the driving device 400 can also be a power mechanism such as a hydraulic cylinder, a pneumatic cylinder, a screw rod, a motor, etc., and this is merely an example. Likewise, in other embodiments of the present invention, the connecting device 510 may also be a driving belt, a gear, a lead screw, etc., which is merely an example and is not limited thereto.

As can be seen from the figures, in the present embodiment of the invention, the supporting frames 200 are respectively disposed at both sides of the upright 520. Specifically, the pillar 520 is disposed in the middle along the width direction of the bottom chassis 100, and the supporting brackets 200 are symmetrically disposed at both sides of the pillar 520. And the height of the first plate 210 is less than that of the upright 520, so that the driving device 400 can easily operate the support stand 200 to turn over.
