[0051] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] The specific structure and loading process of the present invention are described in detail below with reference to the accompanying drawings.

[0053] like Figure 1 and Figure 2 As shown, the present invention provides a carrier suspension launch stand, specifically, comprising: a rotating base 1, a pitch adjustment structure 2 (including a launch cantilever 22 having a mounting position for connecting to a track structure 3), a track structure 3, and a positioning support structure 4.

[0054] The track structure 3 here can be a single track or a split type of multiple tracks spliced ​​together. The present invention is not limited to the single track as shown in the figure. Those skilled in the art can also split it into a structure spliced ​​with multiple tracks according to the length and performance requirements, and can splice different numbers of tracks according to different lengths, which will not be elaborated here.

[0055] like Figure 1 :

[0056] The ear shaft 21 of the launching cantilever 22 is mounted on the mounting column 12 of the rotating base 1. The launching cantilever 22 is provided with a driving assembly 23, so that it can drive the launching cantilever 22 to rotate in the range of 0° to 90° with the axis of the ear shaft 21 as the rotation axis (it should be noted that the angle here is for the adjustment of the pitch angle) to meet the needs of different launching inclination angles.

[0057] Furthermore, in order to improve the recycling efficiency, the rotating base 1 and the launching cantilever 22 can be entirely coated with a heat-resistant coating.

[0058] Specifically, the rotating base 1 can rotate on the table top (i.e., the plane of the launch site) to adjust the circumferential angle. Its specific structure is as follows: a bottom plate 11 with a rotating structure is provided at the bottom of the rotating base 1, which can adjust the launch azimuth angle of the entire launch frame within the range of -90° to 90° (it should be noted that the angle adjustment here is for the circumferential direction, i.e., the adjustment in the steering direction).

[0059] like Figure 2 :

[0060] In this embodiment, the launch vehicle 5 (specifically, a rocket) to be launched is placed on the bottom bracket 42 of the positioning support structure 4 after the final assembly is completed in the final assembly plant, and then the bracket 41 is installed to dock the track structure 3 with the launch vehicle 5 (specifically, a rocket). That is, the bottom bracket 42 and the track structure 3 are connected by installing the bracket 41, so that the launch vehicle 5 to be launched is installed on the track structure 3.

[0061] In a preferred embodiment of the present invention, the positioning support structure 4 may further include: moving wheels 43 and a traction rod 44 .

[0062] The moving wheels 43 and the traction rod 44 are used for positioning the short-distance transfer of the supporting structure 4, so as to facilitate the docking of the track structure 3 with the carrier 5 to be launched (specifically, a rocket) and then transport it from the assembly plant to the launch site.

[0063] like Figure 3 :

[0064] In this embodiment, the launching cantilever 22 is integrated with a lifting motor 24 and a lifting steel cable 25 (it should be further explained that the lifting components formed by the lifting motor 24 and the lifting steel cable 25 here can be multiple groups, preferably two groups, and are symmetrically arranged relative to the launching cantilever 22 to improve the overall lifting stability).

[0065] A lifting point 31 is provided on the track structure 3. After the launch vehicle 5 (specifically, a rocket) is transferred to the launch site, the lifting cable 25 lifts the track structure 3 and the launch vehicle 5 (specifically, a rocket) to the launch boom 22 through the lifting point 31, and then the track structure 3 is fixedly connected to the launch boom 22 using the fixing bolts 26.

[0066] It should be noted that the driving assembly 23 here can be a rotating motor to drive the ear shaft 21 to rotate around the axis, and then drive the launching boom 22 to achieve pitch adjustment.

[0067] Furthermore, since the rotation of the rotary motor drives the ear shaft 21 and the launch cantilever 22, and finally drives the track structure 3 connected to the launch cantilever 22 and the carrier 5 to be launched, the positioning support structure 4 and other overall structures, its load is relatively large and its performance requirements are relatively high. On this basis, the performance requirements can be reduced by setting a gear set between the rotary motor and the ear shaft 21, thereby reducing the use cost while ensuring the stability of the entire structure. For example, a main rotating gear can be sleeved on the rotary motor, and a slave rotating gear can be sleeved on the ear shaft 21, and the main rotating gear and the slave rotating gear are meshed, and the main rotating gear and the slave rotating gear can be further rotatably installed on the mounting column 12, so as to better support the overall load with the help of the mounting column 12.

[0068] However, the rotating motor is still subject to the overall drag force of the hoisted object during its rotation, which can easily cause the rotating motor to have poor stability during its rotation, thereby reducing its service life during long-term use.

[0069] On this basis, if Figure 4 :

[0070] The present invention further proposes a more stable structure of the driving assembly 23 .

[0071] It includes at least one pitch motor 231 arranged on the mounting column 12, and at least one transmission assembly connected between the pitch motor 231 and the rotating part; and,

[0072] The transmission assembly includes a ring gear 232 coaxially connected to the ear shaft 21, a spur gear 233 partially meshed with the ring gear 232, and a support plate 234 mounted on the mounting column 12;

[0073] The support plate 234 is provided with an embedding groove along the extension direction of the spur gear 233, and a strip engaged with the embedding groove is formed on a side of the spur gear 233 away from the meshing teeth. The pitch motor 231 drives the spur gear 233 to move along the extension direction by telescoping, so as to drive the ring gear 232 to drive the ear shaft 21 to rotate.

[0074] Through such a configuration, the overall bearing capacity is mainly released through the spur gear 233 and the support plate 234, effectively reducing the load on the pitch motor 231. Furthermore, the pitch motor 231 is a telescopic motor, which converts the force in the telescopic direction into the rotation direction. Obviously, under a certain downward gravity load, the telescopic transmission has a higher overall stability than the rotary transmission, and the requirements for the motor are relatively lower, further reducing the use cost.

[0075] In summary, the present invention discloses a vehicle suspension launch rack, in which the launch cantilever 22 and the guide rail are designed separately. The guide rails can be replaced for different types of near-space vehicles to meet the needs of vehicles with different structures and different track lengths, thereby improving the versatility of the launch rack.

[0076] Secondly, the split guide rail used in the present invention can be docked with the carrier 5 to be launched in advance in the final assembly plant. The use of final assembly plant equipment can avoid docking operations at the launch site, and there is no need to design and manufacture launch site docking equipment, thereby reducing launch costs.

[0077] Furthermore, the present invention places the rail docking operation link in a highly controlled final assembly plant, thereby improving the safety of the operation.

[0078] In addition, in the present invention, the rotating base 1 and the launching cantilever 22 are coated with a thermal protection coating, so that the carrier suspension launching rack of the present invention has a strong reusability.

[0079] In summary, the present invention adopts a separate design of the launch cantilever 22 and the guide rail on the suspended tilting rocket launcher. Compared with the traditional integrated design, the guide rail type can be replaced according to the structural dimensions and guide rail length requirements of different types of near-space vehicles, thereby improving the versatility of the launcher; the use of a split guide rail can convert the operation site for the docking operation of the carrier and the guide rail into an assembly plant. Compared with the traditional docking operation at the launch site, the need for ground support equipment such as docking vehicles / platforms is eliminated, thereby reducing the launch cost, and the docking operation can be carried out in a more controllable environment, thereby reducing the operation risk; at the same time, the launcher is integrated with a split guide rail lifting structure, and multiple and multi-type near-space vehicles can be quickly launched by replacing the guide rails, greatly shortening the launch interval.

[0080] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
