Description

Technical Field

[0001] This utility model relates to the field of rocket launch technology, specifically to a rocket end journal conversion device that can be used for erection and hoisting. Background Technology

[0002] Typically, a tail section of a rocket body has an end journal for connection to the erector frame, and a foot at the bottom of the tail section, vertically supported by a support device on the upper part of the launch pad support arm. Because the end journal and foot are located at different positions on the rocket, the weight is borne by the end journal during erection, and by the tail end face when the rocket is vertical; both positions experience significant loads. The tail section requires a strong structure, which hinders weight reduction and decreases the rocket's payload capacity.

[0003] To reduce weight, a large launch vehicle has four support positions located in the waist of the tail section. The support method is to distribute horizontal shafts tangentially along the rocket wall. The middle section of the horizontal shaft passes through a bushing and is fixed to the outer wall of the tail section. The usable support positions are the two cylindrical surfaces at both ends of the horizontal shaft. At the same time, the rocket does not have end journals. Therefore, an end journal conversion structure that can be used for the erection and hoisting of the rocket is needed.

[0004] In summary, the existing technology has the following problems: the erection and hoisting of existing large launch vehicles lack conversion structures. Utility Model Content

[0005] This invention provides a rocket end journal conversion device that can be used for erection and hoisting, and solves the technical problem that existing large launch vehicles lack conversion structures for erection and hoisting.

[0006] To achieve the above objectives, this utility model proposes a rocket end journal conversion device that can be used for erection and hoisting, comprising:

[0007] The housing, a first groove provided at the front end of the housing, a first lifting member provided on the side of the housing, and a pad provided between the housing and the first lifting member;

[0008] The first groove is used to connect with the rocket's arrow foot; the first lifting member passes through the shell and the first groove, and the surface of the first lifting member is provided with external threads.

[0009] Specifically, the first lifting component includes: a first lifting ring and a first handle end;

[0010] The first lifting ring is fixedly connected to the first handle end; the first lifting ring protrudes from one side of the housing, and the first handle end protrudes from the other side of the housing;

[0011] The first shank end surface is provided with external threads.

[0012] Specifically, the portion of the first handle protruding from the housing is secured by fasteners.

[0013] Specifically, the fastener and the housing are provided with a pad.

[0014] Specifically, the first groove engages with the rocket's arrowhead, ensuring a tight and reliable fit.

[0015] Specifically, the first lifting component is threadedly connected to the support shaft of the arrow foot.

[0016] Specifically, a connecting part is fixedly connected to the rear end of the shell; the connecting part is used to connect with the rocket erector.

[0017] Specifically, the end face of the connecting part is provided with a second groove. This groove can provide support during installation, facilitating quick and easy installation.

[0018] Specifically, a second lifting component is provided at the top of the shell. Based on the rocket load conditions, the end journal conversion device experiences significant stress, therefore a lifting method is adopted, and the second lifting component serves as the lifting position.

[0019] Specifically, the connecting part is cylindrical in shape.

[0020] This conversion device enables rocket erection without increasing its weight. The absence of an end journal at the rocket's tail end effectively reduces tail weight and increases payload capacity. Furthermore, the end journal conversion mechanism includes lifting lugs and rings for rocket hoisting.

[0021] The beneficial technical effects of the above-mentioned technical solution are as follows: The conversion device of this utility model can be matched with the second and fourth quadrant arrow feet of the rocket. After the rocket is erected, the launch pad receives the first and third quadrant arrow feet, and then the journal conversion mechanism is removed, allowing the launch pad to receive the second and fourth quadrant arrow feet. This conversion device is easy to operate and has a reliable connection. It can meet the requirements for rocket erection without increasing the rocket's weight. Furthermore, the journal conversion mechanism is equipped with lifting lugs for rocket hoisting. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] This utility model embodiment provides a rocket end journal conversion device that can be used for erection and hoisting. The rocket end journal conversion device needs to be used in conjunction with the rocket's arrow foot 2, such as... Figure 1 As shown, it includes: a shell 1, a first groove 16 located at the front end of the shell 1, a first lifting member 12 located on the side of the shell 1, and a pad 13 located between the shell 1 and the first lifting member 12; the shell 1 is the main load-bearing structure, which needs to bear the load of the rocket during erection, and is produced by forging. The shell 1 is designed according to the structural form of the rocket's foot 2 to ensure a tight and reliable connection between it and the rocket's foot 2. Figure 3 As shown, the pad 13 is made of steel and is installed in two places: one between the first lifting component 12 and the outer wall of the shell 1, and the other between the fastener 15 and the shell 1. Its main function is to increase the contact area between the first lifting component 12, the fastener 15 and the shell 1, and to avoid concentrated stress.

[0034] like Figure 5 As shown, the first groove 16 is used to connect with the rocket's arrow foot 2, ensuring a tight and reliable fit between them; wherein, the rocket's arrow foot 2 mainly includes a support body 21 and a support shaft 22, and the support shaft 22 has threads on its inner side. Figure 4 As shown, the first lifting component 12 can penetrate the housing 1 and the first groove 16, and the surface of the first lifting component 12 is provided with external threads; the first lifting component 12 is threadedly connected to the support shaft 22. After assembly, the first groove 16 is in close contact with the outside of the support shaft 22.

[0035] The pad 13 is pressed into contact with the shell 1 via the first lifting component 12. The first lifting component 12 is the tail lifting point when the rocket is hoisted onto the erector frame. It is connected and fixed to the support shaft 22 of the rocket foot via threads, and simultaneously cooperates with the fastener 15 to fix the shell 1 and the rocket foot 2. During operation, the first lifting component 12, as the tail lifting point, bears the weight of the rocket and is subjected to a large load. It is manufactured by forging. The first lifting component 12 includes: a first lifting ring and a first handle end; the first lifting ring and the first handle end are fixedly connected; the first lifting ring protrudes from one side of the shell 1, and the first handle end can protrude from the other side of the shell 1; the surface of the first handle end is provided with external threads. The part of the first handle end protruding from the shell 1 can be fixed by the fastener 15. The fastener 15 is a nut. The fastener 15 is a standard part, and its main function is to cooperate with the first lifting component 12 to fix the shell 1 and the rocket foot 2.

[0036] like Figure 6 As shown, the arrow foot 2 is provided with a support shaft 22, and the outer wall of the support shaft 22 can be engaged with the first groove 16. The inner wall of the support shaft 22 is provided with an internal thread, and the first lifting component 12 is threadedly connected to the support shaft 22.

[0037] In one embodiment, a connecting part 11 is fixedly connected to the rear end of the housing 1. The connecting part 11 can be used to connect to the erecting frame. Furthermore, the connecting part 11 is connected to the rear support on the erecting frame. A second groove 17 is provided on the end face of the connecting part 11, and the connecting part 11 is cylindrical in shape. During installation, tools are needed to support the second groove 17 to complete the installation.

[0038] like Figure 2 As shown, a second lifting component 14 is provided at the top of the shell 1. The second lifting component 14 is the lifting point of the end journal conversion device and is threadedly connected to the shell 1. According to the rocket load, the end journal conversion mechanism is subjected to a large force, so the designed structure is heavy and needs to be installed by lifting. Therefore, the second lifting component 14 is set as the lifting position.

[0039] The method of using the rocket end journal conversion device is as follows:

[0040] a) Before hoisting the rocket onto the erecting frame, the rocket end journal conversion device must be installed with the rocket's arrow feet 2 (two-quadrant and four-quadrant). The installation steps are as follows:

[0041] Thread the second lifting component 14 to the housing 1;

[0042] The shell 1 is assembled with the rocket feet 2 by hoisting.

[0043] Install the first lifting component 12, the pad 13, and the fastener 15, wherein the first lifting component 12 and the fastener 15 are respectively fixed to the support shaft 22 of the arrow foot by threaded connection.

[0044] b) Connect the lifting device to the first lifting component 12, lift the entire rocket to the erecting frame, and connect and fix the end shaft of the rocket end journal conversion device to the rear support of the erecting frame.

[0045] c) Erecting the scaffolding;

[0046] d) such as Figure 7 , Figure 8 As shown, the rocket's first and third quadrant arrow feet land on the platform, and the rear support is disengaged from the rocket's end journal conversion device. The rocket's second and fourth quadrant end journal conversion devices are then removed.

[0047] This utility model has the following beneficial effects:

[0048] The conversion device of this invention can be matched with the second-quadrant and fourth-quadrant arrow feet of a rocket. After the rocket is erected, the launch pad receives the first-quadrant and third-quadrant arrow feet. Then, the journal conversion mechanism is removed, and the launch pad receives the second-quadrant and fourth-quadrant arrow feet. This conversion device is easy to operate and has a reliable connection. It can meet the requirements for rocket erection without increasing the rocket's weight. The rocket's tail end does not require a journal, effectively reducing the weight of the tail end and increasing the rocket's carrying capacity. Simultaneously, the journal conversion mechanism is equipped with lifting lugs and rings for rocket hoisting, meeting the multi-functional requirements of rocket erection and hoisting.

[0049] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. The various components of this utility model can be combined with each other without conflict. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
