Utility Model Content
[0003] The technical problem solved by this utility model is to overcome the shortcomings of the prior art. This utility model provides a tooling for storing solid rocket engines, which solves the problem of low space utilization of single-layer brackets in the prior art.
[0004] The solution of this utility model is: a tooling for storing solid rocket engines, comprising a first-layer arc frame and a second-layer arc frame; the second-layer arc frame is located above the first-layer arc frame, and the two are connected by a common central axis; the first-layer arc frame is an integrated design structure, with a horizontal base plate on the bottom surface and an arc plate I at the center of the top surface, with both ends of the arc plate I connected to an upper flat plate; the second-layer arc frame includes legs, crossbeams, longitudinal beams, and an arc plate II; the crossbeams and longitudinal beams are vertically connected to form a horizontal rectangular bracket; the arc plate II is fixed above the rectangular bracket; the four legs are vertically connected to the lower corners of the rectangular bracket respectively.
[0005] Furthermore, each of the four legs is provided with a guide hole.
[0006] Furthermore, the first-layer arc-shaped frame is provided with guide pins, and the guide pins are matched with the guide holes in size and quantity, for positioning, assembly and connection of the first-layer arc-shaped frame and the second-layer arc-shaped frame.
[0007] Furthermore, four diagonal braces are added between the support legs and the crossbeam, and a reinforcing rod parallel to the longitudinal beam is added between the two support legs connecting the longitudinal beam to enhance the stability of the two-layer arc frame.
[0008] Furthermore, the outer surfaces of the outriggers and diagonal braces are covered with protective sleeves to protect the engine housing from damage by the bracket.
[0009] Furthermore, the support wrap angles of both the arc-shaped plate I and the arc-shaped plate II are 120°.
[0010] Furthermore, a felt pad I is attached to the surface of the arc-shaped plate I, and a felt pad II is attached to the surface of the arc-shaped plate II, to prevent the engine from being bumped or struck.

[0017] Figure 2 This is a side view of the present invention;
[0018] Figure 3 This is a top view of the present invention. Detailed Implementation
[0019] The present invention will be further explained and described below with reference to the accompanying drawings and specific embodiments.
[0020] like Figure 1 As shown, a tooling for storing solid rocket motors includes a first-layer arc-shaped frame 1 and a second-layer arc-shaped frame 8; the second-layer arc-shaped frame 8 is located above the first-layer arc-shaped frame 1. The first-layer arc-shaped frame 1 includes a base plate 2, an arc-shaped plate 3, a felt pad 4, a handle 6, an upper plate 5, and a guide pin 7; the second-layer arc-shaped frame 8 includes legs 9, diagonal braces 10, a protective sleeve 11, a crossbeam 12, a reinforcing rod 13, a longitudinal beam 14, an arc-shaped plate 15, a felt pad 16, and a handle 17.
[0021] The base plate 2 of the first-layer arc-shaped frame 1 is completely in contact with the ground, ensuring the stability of the entire bracket during use.
[0022] The second-layer arc frame 8 is equipped with four legs 9, and four diagonal braces 10 are added between the legs 9 and the crossbeam 12. Two reinforcing rods 13 are connected in the middle of the legs 9 below the longitudinal beam 14, which further enhances the stability of the second-layer arc frame 8.
[0023] The protective cover 11 is made of rubber foam sponge and is attached to the outer surface of the support leg 9 and the diagonal brace 10 to protect the engine housing from being damaged by the bracket.
[0024] Guide pin 7 is fixed to the first-layer arc frame 1, and the second-layer arc frame 8 is provided with guide holes that cooperate with guide pin 7. When installing the second-layer arc frame 8, simply insert guide pin 7 into the guide hole to quickly and accurately complete the positioning of the two layers of arc frames, improving installation efficiency and positioning accuracy.
[0025] Handles 6 and 17 are welded to the sides of the first-layer arc frame 1 and the second-layer arc frame 8, respectively, to facilitate the lifting, unloading and transfer of the arc frame.
[0026] The support angles of the arc plate 3 and the arc plate 15 are both 120°. The surfaces of the arc plate 3 and the arc plate 15 are covered with 15mm thick felt pads 4 and 16 to prevent the engine from being bumped.
[0027] A nameplate 18 is provided on the outer side of the first-layer arc-shaped frame 1.
[0028] The specific implementation method is as follows:
[0029] During installation, first place the first layer of the arc frame 1 in the designated storage location and check that the base plate 2 is in close contact with the ground to ensure the stability of the first layer of the arc frame 1.
[0030] Then, the second-layer arc frame 8 is hoisted above the first-layer arc frame 1. By controlling the position and angle of the support legs 9, the guide pin 7 of the first-layer arc frame 1 is aligned with the guide hole of the second-layer arc frame 8. The second-layer arc frame 8 is slowly lowered, and the guide pin 7 is inserted into the guide hole of the support leg 9, completing the positioning and installation between the first-layer arc frame 1 and the second-layer arc frame 8.
[0031] During disassembly, first lift the products placed on the second-layer arc-shaped frame 8 to the ground arc-shaped frame.
[0032] The second-layer curved frame 8 is vertically hoisted, with personnel at the four corners holding the outriggers 9. Once the bottom of the outriggers 9 is higher than the product, it can be moved horizontally away from the first-layer curved frame 1 and placed in an open space.
[0033] Finally, the product placed on the first layer of curved frame 1 is hoisted to a suitable location.
[0034] This utility model presents a simple and practical tooling structure for storing solid rocket engines, effectively improving storage space utilization and ensuring engine safety during hoisting and storage. The dimensions of the double-layer arc-shaped frame can be determined according to the engine diameter and length to meet production needs. When the engine diameter changes, the diameter and width of the placement bracket can be adjusted to meet the product's storage requirements.

Any person skilled in the art can make possible changes and modifications to the technical solution of the present invention by utilizing the methods and techniques disclosed above without departing from the spirit and scope of the present invention. Therefore, any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention shall fall within the protection scope of the technical solution of the present invention.
