Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict. For convenience of description, the words "upper", "lower", "left" and "right" in the following description are used only to indicate the correspondence between the upper, lower, left and right directions of the drawings themselves, and do not limit the structure.

A double-deck transportation rack for laminated plates is mainly formed by assembling an upper layer and a lower layer of two identical transportation rack units 10 from top to bottom as shown in figure 4. Generally, the whole transportation goods shelf is mainly formed by welding section steel.

As shown in fig. 1-3, a single transport rack unit 10 is mainly composed of three major parts, namely, a bottom frame, a vertical column 8 and a connecting piece. Wherein the chassis mainly comprises two chassis longerons 1 and two welding of chassis crossbeam 2, still is equipped with angle reinforcement 5 in the bight position of connecting, in addition, still welds a plurality of strengthening beam 3 between two chassis longerons 1, and this embodiment is 4 channel-section steels. The stand 8 comprises the channel-section steel welding, and the top of stand 8 is fixed with location awl 9, and the connecting piece mainly comprises bolt 6, position sleeve 7 and location awl 9. The underframe, the upright post 8 and the connecting piece are welded and connected. As shown in fig. 5 and 6, the upper and lower transportation shelf units are connected through a connecting piece, on one hand, the lower transportation shelf unit extends into the positioning sleeve 7 at the bottom of the upper transportation shelf unit through the positioning cone 9 protruding from the top of the upright post 8 to be clamped, so that the upper and lower shelves can be prevented from moving horizontally in the transportation process; on the other hand, the upper layer transportation goods shelf unit and the lower layer transportation goods shelf unit are connected through the bolt 6, so that the horizontal movement of the upper layer transportation goods shelf unit and the lower layer transportation goods shelf unit and the toppling of the upper layer transportation goods shelf unit can be prevented in the transportation process.

When the combined slab conveying device is used for conveying the combined slabs, firstly, workers hoist the bottom layer conveying shelf unit to a conveying vehicle, then integrally hoist the stacked combined slabs (generally 6-7 blocks) to a conveying shelf, then hoist the upper layer conveying shelf unit to the bottom layer conveying shelf unit and fix the upper layer conveying shelf unit, and finally integrally hoist the stacked combined slabs (generally 6-7 blocks) to the upper layer conveying shelf unit by using a forklift or a crane.

Of course, the laminated plate can be placed into the upper and lower layer transportation goods shelf units on the ground, then the upper and lower layer transportation goods shelf units are stacked and fixed by utilizing the hoisting equipment, and finally the double-layer transportation goods shelf is integrally hoisted to the upper surface of the transportation vehicle.

The type and specification of the bottom support and the upright post of the transportation shelf of the embodiment can be changed into other similar forms if the stress requirements are met. In addition, the connection mode of the upper layer transportation goods shelf and the lower layer transportation goods shelf can be replaced by a bolt connection mode or other modes.

The above-mentioned embodiments are to be construed as illustrative and not limitative of the remainder of the disclosure, and it is to be understood that various equivalent modifications can be made without departing from the spirit and scope of the disclosure as set forth in the appended claims.
