[0002] The launch tube is mostly made of composite materials and uses a wet continuous fiber winding process. After winding and curing on a core mold that meets the inner diameter requirements, the launch tube and the core mold are separated, that is, demoulding. During the demoulding process of the launch tube, a large force is required to overcome the adhesion, adsorption and friction between the launch tube body and the core mold. At the same time, the coaxiality between the launch tube body and the core mold must be ensured to prevent the inner surface of the launch tube from being scratched.

The existing vertical demoulding technology is only suitable for small launch tubes, and has a complex structure, is difficult to design and manufacture, and has a long cycle. Therefore, there is an urgent need for a vertical launch tube demoulding device suitable for launch tubes of various specifications, which reduces the occupation of horizontal space, enhances convenience, and is suitable for large and medium-sized launch tubes.

[0031] It should be noted that, unless otherwise specified, all components in the present invention are components known in the prior art. For example, the launch tube adopts a known and commonly used launch tube.

[0032] The following are specific embodiments of the present invention. It should be noted that the present invention is not limited to the following specific embodiments, and all equivalent changes made on the basis of the technical solution of the present application fall within the protection scope of the present invention.

[0033] like Figures 1 to 3 As shown, a vertical launch tube demoulding device comprises a launch tube 1 and a supporting device 2; a lower fixing ring 3 and a lower bearing ring 4 are fixedly sleeved on the lower part of the launch tube 1 in sequence from bottom to top, and the lower fixing ring 3 is fixedly connected to the lower bearing ring 4.

[0034] The outer ring of the upper end of the lower bearing ring 4 is evenly provided with a plurality of terminal posts 5 along the circumferential direction; the inner ring of the lower bearing ring 4 is evenly provided with a plurality of vertically penetrating threading holes 6 along the circumferential direction.

[0035] The supporting device 2 comprises a supporting ring 201 ; a plurality of supporting legs 202 are evenly arranged at the lower end of the supporting ring 201 ; and a lower fixing ring 3 is arranged on the supporting ring 201 .

[0036] The inner circle of the support ring 201 is evenly provided with a plurality of winding holes 203 corresponding to the terminal posts 5 along the circumferential direction; the lower end of the support ring 201 is evenly provided with a plurality of winding posts 204 corresponding to the winding holes 203 along the circumferential direction.

[0037] When the vertical launch tube demoulding device of the utility model is in use, the launch tube 1 is vertically set on the ground through the support device 2, and the support device 2 can also prevent the launch tube 1 demoulding device from tipping over or falling after the core mold is pulled out;

[0038] When demolding is required, conventional devices such as wire rope are used, with one end fixed on the winding post 204 of the support ring 201, and the other end passes through the threading hole 6 of the lower bearing ring 4 and then passes through the winding hole 203 of the support ring 201 again, then passes around the terminal 5 and then winds into the next winding post 204... and so on, and finally the support device 2 is connected to the body of the launch tube 1 through multiple windings.

[0039] Subsequently, it is only necessary to use an external lifting device such as an oil hoist to vertically pull up the core shaft inside the launch tube 1. This arrangement is easy to install and use while having high reliability. It is suitable for launch tubes of various specifications, and the vertical demoulding form it adopts reduces the floor space occupied.

[0040] Specifically, the connection between the lower fixing ring 3 and the lower bearing ring 4 is a flange connection, which enhances the connection strength between the two.

[0041] As a preferred solution, Figure 4 and 5 As shown, a plurality of threaded holes 7 are evenly formed on the lower bearing ring 4 along the circumferential direction; all threaded holes 7 do not contact any terminal 5 or threading hole 6;

[0042] The inner side of the support ring 201 is uniformly provided with matching grooves 8 corresponding to the threaded holes 7 along the circumferential direction;

[0043] The bolts of the flange connection between the lower bearing ring 4 and the lower fixing ring 3 enter the adapter groove 8 one by one, making the launch tube 1 placed on the supporting device 2 more stable.

[0044] As a preferred solution, the numbers of threaded holes 7, terminal posts 5 and threading holes 6 are equal.

[0047] When in use, the wire rope is inserted in a similar manner to the above method. Before the wire rope is inserted into the next winding post 204, it first passes around the terminal of the upper bearing ring 10, and then passes through the threading hole of the upper bearing ring 10 and then into the next winding post 204. This arrangement further enhances the reliability of the connection between the launch tube 1 and the support device 2.

[0048] Specifically, three supporting legs 202 are evenly arranged along the circumferential direction on the outer circle of the bottom end of the supporting ring 201 .
