[0027] In order to further understand the content, features and effects of the present invention, the following embodiments are given to explain in detail.

[0028] See also Figure 1 , Figure 2 and Figure 3 The rocket multi-angle positioning and tilting launching device of the present invention includes a frame-type base 1 fixed to the ground and capable of being hoisted and transferred, and also includes a launching arm 2 and a positioning support frame 3, wherein the frame-type base 1 is used to support the auxiliary components, is fixed to the ground when performing the rocket launching operation, withstands the reverse impact force during the rocket launching, and ensures the stability of the launching process, the launching arm 2 is connected to the rocket, and during the launching, the rocket is launched along the launching direction set by the launching arm 2, and the positioning support frame 3 is used to support the launching arm 2 and quickly adjust the launching arm 2 to the desired launching angle.

[0029] See also Figure 4 , we can see that:

[0030] The frame-type base 1 comprises a base frame, on which a front bracket 13 and a rear bracket 14 are mounted, on which a positioning seat 6 is mounted, on which two opposite rotating shaft mounting seats 15 are mounted, and on which a rotating shaft 16 is mounted.

[0031] As shown in the figure, the base frame of the frame-type base 1 includes a rectangular frame located outside, a plurality of longitudinal profiles are welded and installed inside the rectangular frame, and transverse profiles are welded and installed between adjacent longitudinal profiles. A plurality of fixed base plates 12 are provided at the bottom of the rectangular frame, and each fixed base plate 12 is fixedly connected to the ground by an expansion bolt 11. A plurality of U-shaped lifting rings 17 are also installed on the rectangular frame. The U-shaped lifting rings 17 are provided to assist in the lifting and transfer of the frame-type base 1. The rectangular frame, longitudinal profiles, and transverse profiles of the base frame are welded and fixed to ensure the overall structural strength of the base frame. A plurality of fixed base plates 12 are welded and installed on the frame and four corners of the rectangular frame to provide a multi-point fixing function. The U-shaped lifting rings 17 are installed on the rectangular frame by welding. Two U-shaped lifting rings 17 are provided at the front, middle, and rear to achieve multi-point lifting and ensure the stability of lifting and transfer.

[0032] The front bracket 13 includes a bottom support plate, a top support plate, and a support rod between the two support plates, and the bottom support plate is fixedly connected to the rectangular frame by a plurality of bolts, so that the front bracket 13 can be disassembled. Similarly, the rear bracket 14 includes a bottom support plate, a top support plate, and a support rod between the two support plates, and the bottom support plate is fixedly connected to the rectangular frame by a plurality of bolts, so that the rear bracket 14 can be disassembled.

[0033] See also Figure 4 and Figure 7 , we can see that:

[0034] The rotating shaft mounting seat 15 includes a rotating shaft base 152 and a pressing block 151. The rotating shaft base 152 is fixed to the top support plate of the rear bracket 14 by bolts. A groove is provided at the top of the rotating shaft base 152 and the bottom of the pressing block 151, and the rotating shaft 16 is located in the groove (the upper and lower semicircular grooves together constitute an axial hole for accommodating the rotating shaft 16). The pressing block 151 is fixedly connected to the rotating shaft base 152 by screws.

[0035] In this embodiment, considering the need to intuitively display the currently adjusted launch angle, an angle indicating assembly 5 is also installed on the outer side of one of the rotating shaft mounting seats 15, and the angle indicating assembly 5 includes a dial 51 fixed to the rotating shaft base 152 of the rotating shaft mounting seat 15 and an indicating needle 52 installed on the outer end of the rotating shaft 16 on this side. The dial 51 is fixedly connected to the rotating shaft base 152 by screws, and the indicating needle 52 is fixedly connected to the outer end of the rotating shaft 16 by screws. The rotating shaft 16 rotates synchronously with the launching arm 2, and accordingly, the indicating needle 52 deflects and indicates the current angle value on the dial 51.

[0036] See also Figure 5 , we can see that:

[0037] The launching arm 2 includes a launching arm profile 21, a launching guide rail 23 extending along the length direction is installed on the top of the launching arm profile 21, a shaft sleeve 26 is installed at the root of the launching arm profile 21, and two rotating shafts 16 are inserted and fixed in the shaft sleeve 26, and a plurality of positioning support ears 25 are installed at the front lower part of the launching arm profile 21.

[0038] Among them, the launch arm profile 21 is used as a supporting profile, and the launch rail 23 is used to connect with the rocket. After the launch arm profile 21 is adjusted to a suitable launch angle, the rocket slides along the launch rail 23 and is launched. The sleeve 26 is used to cooperate with the rotating shaft 16. Since the rotating shaft 16 and the sleeve 26 are in a plug-in fixed relationship, when the launch arm 2 is adjusted in angle, the sleeve 26 drives the rotating shaft 16 to rotate synchronously, thereby driving the indicator needle 52 to rotate synchronously, and the adjusted launch angle can be indicated on the dial 51. Each group of positioning support ears 25 corresponds to a set launch angle value. When the support arm 2 is supported by the positioning support frame 3 to a tilted state, the positioning support frame 3 is selectively fixedly connected to one group of positioning support ears 25 according to the setting requirements for the launch angle.

[0039] In this embodiment, the launch arm profile 21 of the launch arm 2 is an H-shaped steel. In order to improve the overall structural strength, a plurality of reinforcing ribs are welded and installed on both sides of the H-shaped steel. A guide rail base 22 is welded and installed on the top of the launch arm profile 21, and the launch rail 23 is fixedly connected to the guide rail base 22 by bolts. The guide rail base 22 is a flat metal plate, which is installed and fixed on the top of the launch arm profile 21 by welding. After welding and installation, the surface of the guide rail base 22 is machined to improve the flatness of the surface, and then the launch rail 23 is installed. This can ensure the straightness of the launch rail 23 after installation and improve the stability of the rocket launch.

[0040] In this embodiment, the launch guide rail 23 is a multi-section spliced ​​guide rail, and a track groove with a rectangular cross-section is provided on the launch guide rail 23. The track groove is used to cooperate with a slider installed on the rocket. A detachable slider cover covering the track groove port is installed at the rear end of the launch guide rail 23. When loading the rocket, the slider cover is removed, so that the track groove port is opened. After the loading of the rocket is completed, the slider cover is installed, and the slider on the rocket cannot escape from the track groove of the launch guide rail 23.

[0041] In this embodiment, three groups of positioning support ears 25 are provided, and each group of positioning support ears includes two opposite support ear monomers with connection holes, and the top edge of the support ear monomer is welded and fixed to the bottom of the launch arm profile 21.

[0042] In this embodiment, the launch arm 2 further includes a plurality of lifting ears 24, which are metal tubes with threaded holes in the middle, and are welded and installed on the launch arm profile 21. As shown in the figure, there are three lifting ears 24, which are respectively installed at the front, middle front and middle rear of the launch arm 2. When the launch arm 2 needs to be hoisted and transferred and the launch angle of the launch arm 2 needs to be hoisted and adjusted, the connector at the lower end of the hoisting cable is connected to the lifting ear 24. Specifically, the connector is two threaded rods, and the two threaded rods are respectively threadedly connected to the two ends of the lifting ear 24.

[0043] See also Figure 6 , we can see that:

[0044] The positioning support frame 3 includes a support frame body 31, and positioning shafts 32 are provided at the upper and lower ends of the support frame body 31. The upper positioning shaft 32 is connected to one set of positioning support ears 25, and the lower positioning shaft 32 is fixedly connected to the positioning seat 6. The function of the positioning support frame 3 is to support the launch arm 2 to a set launch angle.

[0045] In this embodiment, the support frame body 31 includes opposite side profiles and a connecting profile located between the side profiles, and both ends of the connecting profile are welded and fixed to the side profiles. Axial holes are provided at the top and bottom of the two side profiles, and copper sleeves 34 are embedded in the axial holes. Positioning shafts 32 at the upper end are provided with limiting steel sleeves 33 at both ends, and the upper and lower ends of the positioning shafts 32 are provided with threaded portions and locking nuts 35 at both ends.

[0046] As shown in the figure, the structure of the support frame body 31 is similar to a ladder to ensure the overall structural strength. The copper sleeve 34 serves as the sleeve of the positioning shaft 32, and the limit steel sleeve 33 serves as a cushion when the upper positioning shaft 32 is connected to the positioning support ear 25. In this way, the upper end of the positioning support frame 3 can be located in the middle of the two support ear monomers of the positioning support ear 25 to avoid the problem of offset support. Since the positioning shaft 32 at the lower end is only used to connect with the positioning seat 6, there is no problem of offset support, so the limit steel sleeve 33 is not set on the positioning shaft 32 at the lower end.

[0047] The positioning seat 6 includes a positioning seat body, and a plurality of grooves for accommodating the positioning shaft 32 are provided on the top of the positioning seat body. A detachable positioning pressure cover is also installed on the top of the positioning seat body. When it is necessary to connect the lower end of the positioning support frame 3 with the positioning seat 6, the positioning pressure cover is first removed, and the positioning shaft 32 at the lower end is placed into one of the grooves on the top of the positioning seat body and then the positioning pressure cover is reinstalled. At this time, the positioning shaft 32 at the lower end cannot fall off from the positioning seat 6.

[0048] In this embodiment, a mounting hole is provided on the top support plate of the front bracket 13, and the positioning seat body of the positioning seat 6 is fixedly connected to the top support plate of the front bracket 13 by bolts. The purpose of providing multiple grooves on the top of the positioning seat body is to enable the positioning shaft 32 at the lower end of the positioning support frame 3 to be selectively installed in one of the grooves, so that the launch angle of the launch arm 2 can be finely adjusted by selecting different grooves.

[0049] An auxiliary loading assembly 4 or an arrow shield 7 is installed at the rear end of the launch arm 2, and only one of the auxiliary loading assembly 4 and the arrow shield 7 is installed at the rear end of the launch arm 2. The auxiliary loading assembly 4 is installed at the rear end of the launch arm 2 when the rocket is loaded, and is used to assist the loading and is removed after the loading operation is completed. The arrow shield 7 is installed at the rear of the launch arm 2 after the rocket is loaded, so that the rocket will not fall off the launch arm 2 during the process of the launch arm 2 being turned upside down until the launch.

[0050] In this embodiment, the auxiliary loading assembly 4 is fixed to the rear end of the launch arm 2 by bolts, and includes a loading pallet fixedly connected to the rear end of the launch arm profile 21. A slider guide groove is provided in the middle of the loading pallet, and the front end of the slider guide groove is docked with the rear end of the launch guide rail 23. After the auxiliary loading assembly 4 is installed, the loading of the rocket onto the launch arm 2 is assisted, and the slider on the rocket first enters the slider guide groove, and then is guided forward into the track groove on the launch track 23.

[0051] In this embodiment, the arrow shield 7 is fixed to the rear end of the launching arm 2 by means of bolts, that is, it is fixed to the rear end of the launching arm profile 21 by means of bolts.

[0052] How to do it:

[0053] (1) Leveling device

[0054] Before loading the rocket, the launch device is placed according to the launch direction and the frame base 1 is leveled by a horizontal adjustment tool, and the frame base 1 is installed and fixed on the ground by expansion bolts 11 to ensure the stability of the installation and fixation to prevent the launch device from being overturned by the reaction force during the rocket launch, thereby ensuring the accuracy of the launch direction.

[0055] (2) Loading into orbit

[0056] First, install the auxiliary loading assembly 4 at the rear end of the launching arm 2, remove the slider cover at the rear end of the launching guide rail 23, then lift the whole arrow horizontally so that its slider is aligned with the loading entrance of the auxiliary loading assembly 4 (i.e., the entrance of the slider guide groove), and pull the rocket horizontally into the orbit (the slider on the rocket enters the track groove on the launching guide rail 23); then remove the auxiliary loading assembly 4, replace it with the arrow shield 7, and reinstall the slider cover.

[0057] (3) Flip and stand upright

[0058] Connect the hoisting cable of the crane to the lifting ear 25 of the launch arm, flip and erect the launch arm 2 and the rocket, at this time, the shaft sleeve 26 and the rotating shaft 16 drive the indicator needle 52 to rotate, and the current launch angle value is indicated on the dial 51; according to the set launch angle, when the launch arm 2 and the rocket are flipped and erected to a certain extent, connect the positioning shaft 32 at the upper end of the positioning support frame 3 with the positioning support ear 25 at a specific position (first remove the locking nut 35, then remove the positioning shaft 32 and its limiting steel sleeve 33, then align the shaft hole at the upper end with the connecting hole on the selected positioning support ear 25, re-insert the positioning shaft 32 and install the limiting steel sleeve 33, and then tighten the locking nuts 35 at both ends);

[0059] Continue the flipping and erecting operation until the flipping and erecting reaches the set angle, set the positioning shaft 32 at the lower end of the positioning support frame 3 in the specific position groove of the positioning seat 6, and then install and fix the positioning cover to complete the flipping and erecting process;

[0060] The launch angle can be calibrated with the help of an angle instrument. If the launch angle does not reach the set value, the positioning cover of the positioning seat 6 can be removed, and then the positioning shaft 32 at the lower end can be set in another more suitable groove to achieve fine-tuning of the launch angle. After fine-tuning, the positioning cover can be reinstalled to achieve precise matching of the launch angle. Practice has proved that the launch device improves the launch positioning accuracy of the rocket and reduces the adjustment time of the launch angle.
