Problems solved by technology

The traditional blade packaging box uses wooden packaging, which is not only costly and wastes wood, but also because of the change of the twist angle of the blade, it is often necessary to use expanded polystyrene to fix the blade
However, in today's increasingly stringent environmental protection requirements, places such as Europe and France have banned the use of expanded polystyrene, which makes the method of fixing with foam materials no longer applicable.
On the other hand, due to the large number of stages of rotary power machinery and the large number of blades in each stage, the purchaser's order demand for each cycle is also changing, which makes the packaging boxes used by the manufacturer for delivery more specifications, which is easy to cause waste and the packaging cost is huge.

Embodiment 1

[0028] In the packing box of the blade of this embodiment, the tenon of the blade is not exposed outside the blade, and the structure is as follows: figure 1 As shown, its composition includes a rectangular parallelepiped box body 1, a lower base plate 2 placed on the bottom of the box body to match the shape and size of the bottom during assembly, and a plurality of vane chambers 4-1 arranged in an array stacked on the lower base plate. The airfoil retention layer 4 and the upper backing plate 7 overlapped on the airfoil retention layer, the blade chamber is a rectangular grid, and each blade chamber is equipped with two right-angled triangular prism stoppers 5, so that the two A triangular prism is inserted into the blade to occupy two diagonal spaces of the blade chamber, and only a gap matching the size of the blade body of the rotary power machinery is reserved on the diagonal surface for fixing the blade body after the blade is inserted. The packaging box is made of corr...

Embodiment 2

[0030] This embodiment is a packing box for packing single tenon blades, the structure is as follows figure 2 as shown ( figure 2 Only two vane chamber units are shown in ), the structural difference from embodiment 1 is: on the basis of the packing box structure described in embodiment 1, a tenon positioning plate 3 is added (such as image 3 shown), during packaging, the tenon positioning plate is placed between the blade body retention layer and the lower backing plate. Hole 3-1, the blade vertically placed in the blade 6 chamber is inserted into the tenon 6-1 positioning hole by the lower end tenon for positioning. The tenon positioning plate is formed by overlapping and bonding multiple layers of corrugated cardboard, thereby ensuring the strength as a spacer and after accommodating the tenon. In order to adapt to the large amount of shipping packaging and meet the needs of packaging strength and compression resistance, the upper backing board and the lower backing bo...

Embodiment 3

[0032] This embodiment is a packing box for packing a single tenon blade, such as Figure 8 As shown, the structure is the same as that of Embodiment 2, only in order to adapt to a smaller amount of blade packaging, the size of the box body and various components and the number of blade units are reduced.

Abstract

The invention provides a storage and transportation packaging box for blades of a rotary power machine. The storage and transportation packaging box mainly structurally comprises a box body, a lower cushion plate placed at the bottom of the box body and matched with the shape and size of the bottom of the box body, a blade body retention layer overlaid above the lower cushion plate and formed by arranging a plurality of blade chamber arrays and an upper cushion plate overlapped on the blade body retention layer. Each blade chamber is a rectangular frame grid, each blade chamber is provided with two right-angle triangular prism stop blocks, so that two triangular prisms are inserted in a blade to occupy two opposite angle spaces of the blade chamber, and a slit matched with the size of a blade body of a gas turbine blade is reserved only at the position of the diagonal plane, to fix the blade body after the blade is inserted. Under the conditions that the environmental protection requirements are met, namely foamed plastic materials are not used, packaging positioning and protection of the blades of the rotary power machine during storage and transportation are implemented, the packaging cost is reduced, and the suitability of a series of packaging boxes to the multi-model multi-batch blades is improved.

Description

technical field [0001] The invention relates to the packaging of rotary power machine blades, in particular to a packing box for the transportation and storage of rotary power machine blades. Background technique [0002] Blades are one of the important components of rotary power machinery such as gas turbines and aero-engines. Today, with the globalization of rotary power machinery manufacturing, long-distance transportation of blades is very common. In order to meet the needs of protecting blades from deformation and damage during transportation and storage, blades Packaging is essential. The shape of the blade is irregular, the thickness, size and twist angle of the blade shape vary greatly, the tenons are various, and the surface of some blades is coated, which requires high positioning and protection functions of the packaging box, which is a problem that the purchaser pays special attention to. The traditional blade packing box uses wooden packaging, which is not only...
