It will be apparent to those skilled in the art that various modifications and variations can be made in the embodiments of the present disclosure without departing from the scope or spirit of the disclosure. Other embodiments will be apparent to those skilled in the art from consideration of the specification. The specification and examples are exemplary only.
The utility model provides a be used for rocket to rise device. Referring to fig. 1 and 2, the rocket launching device includes: a raising arm 1, an umbilical rod 2 connected to the raising arm 1, and a power cylinder 3 for rotating the umbilical rod 2 relative to the raising arm 1.
In the first direction S1 along the length, one end of the rising arm 1 and one end of the umbilical rod 2 have a coaxial shaft connecting hole, and the rising arm 1 and the umbilical rod 2 are connected to each other by a shaft through the coaxially disposed shaft connecting hole. One end of the power cylinder 3 is fixedly connected to the part of the umbilical rod 2 close to the rotating shaft, and the other end of the power cylinder is fixedly connected with a fixing piece or a vertical arm of a transmitting field.
When the umbilical rod 2 is detached from the erecting arm 1 (for example, in the case where the umbilical rod supports the rocket in a vertical state and the erecting arm is previously leveled back), the power cylinder 3 is used to pull the umbilical rod 2 to rotate around the rotation axis toward the erecting arm 1 by retraction.
One side of the umbilical rod 2 is provided with a support structure 21 for supporting the rocket to be launched.
The erecting arm 1 is used for driving the umbilical cord rod 2 and the rocket to be launched to complete erecting operation from a horizontal state to a vertical state through the erecting oil cylinder, and after the rocket to be launched is in butt joint with the launching platform, the erecting arm 1 is leveled back through the erecting oil cylinder in advance, so that at the moment before the rocket to be launched takes off, the umbilical cord rod 2 is quickly rotated towards the erecting arm under the retraction effect of the power cylinder 3 and then is overturned, and the taking-off space of the rocket is avoided.
The utility model discloses play and erect the device, through the rotatable connection umbilical cord pole in the tip that plays the erector arm to play when erecting the rocket with play the erector arm combined action, and after rocket and launch pad butt joint, play the erector arm and can go back to tie in advance, only support necessary pipeline by umbilical cord pole, thereby make things convenient for the umbilical cord pole to take off at the rocket and fall after quick in the twinkling of an eye, improved the reliability of rocket transmission.
Referring to fig. 2 and 3, in one embodiment, the support structure 21 includes upper supports 22 spaced apart along a length direction S1 thereof, a plurality of auxiliary supports 23, and a clasping mechanism 24, wherein the clasping mechanism 24 is fixedly disposed on the upper supports 22. These support structures 21 are arranged on the side of the umbilical rod 2 contacting the rocket, and an upper support 22 provided with a clasping clamp structure 24 is arranged at the position of the umbilical rod 2 far from the rotating shaft 11, so that the rocket 4 is in a vertical state, and the clasping clamp structure 14 is used for assisting in supporting the front end of the rocket 4. Wherein, a plurality of auxiliary supports 23 can be arc-shaped bracket structures for matching the periphery of the rocket. The clasping clamp structure 24 is arranged on the upper support 22 so as to increase the contact area with the periphery of the rocket 4 in a vertical state and avoid the situation that the rocket 4 topples or slides out of the arc-shaped bracket.
For example, the size and mass of each support structure provided on one side of the umbilical rod 2 may gradually decrease from the end away from the rotation shaft 11 to the end close to the rotation shaft 11. In the process that rocket 4 erects to vertical state from the horizontality, the power that umbilical cord pole 2 received is the biggest keeping away from the arc bracket that pivot 11 position set up, and the power that the arc bracket that is close to pivot 11 side received is less, through setting up the arc bracket of unidimensional, different quality at umbilical cord pole 2, can be guaranteeing to further reduce the weight of umbilical cord pole under the prerequisite of rocket 4 reliable support, makes things convenient for the back of umbilical cord pole to fall the operation.
In addition, since the process of falling back the umbilical cord rod 2 is realized by surrounding the rotating shaft 11, when the umbilical cord rod 2 falls back, the distance of movement of the arc bracket far away from the rotating shaft 11 is the largest, and the actual displacement of the arc bracket is gradually reduced as the arc bracket approaches the rotating shaft 11. Therefore, by reducing the size of the arc-shaped brackets near the rotating shaft 11, the arc-shaped brackets can be better ensured not to interfere with the takeoff of the rocket, and the reliability of rocket launching is improved.

Namely, in the starting process of arranging the rocket 4 in the arc-shaped bracket of the umbilical cord rod 2 and starting the rocket 4 along with the umbilical cord rod 2, each arc-shaped bracket can be uniformly loaded with a system in a hydraulic, pneumatic or mechanical mode and the like so as to adjust the stress of each arc-shaped bracket, effectively avoid the overlarge stress of a single supporting point and improve the safety and reliability of the rocket in the erecting process.
In one embodiment, the power cylinder 3 may be a pneumatic or hydraulic cylinder. When the power cylinder is a hydraulic oil cylinder, the extension and the shortening of the oil cylinder are realized by injecting hydraulic oil into the oil cylinder through a hydraulic oil source. For example, before the rocket 4 is lifted and takes off completely, a large amount of hydraulic oil can be injected into the hydraulic oil cylinder through the hydraulic oil source to be quickly shortened, and the umbilical rod 2 in the vertical state is pulled to quickly fall back. Similarly, if the power cylinder 3 is a pneumatic cylinder, the extension and contraction of the pneumatic cylinder can be controlled by pumping or discharging gas into the power cylinder 3, and the corresponding action of the pneumatic cylinder on the umbilical rod 2 can be realized.
In this embodiment, the power cylinder 3 may be a plurality of hydraulic cylinders arranged in series or in parallel. For example, the hydraulic cylinder may be two independent cylinders connected in series, or may be 3 or more hydraulic cylinders. Therefore, two or more oil cylinders can act independently or simultaneously, and the function of the whole power cylinder system is not influenced after the single point fails.
In this embodiment, for example, one end of the hydraulic cylinder may be fixed to the umbilical rod 2 and the other end may be fixed to a fixing member provided to the erector arm 1 or on the other side of the erector arm 1. Specifically, one end of the hydraulic cylinder may be secured to the umbilical rod 2 by a locking structure and the other end is adapted to be mounted to an ear plate secured to the launch floor. Further, one end of the hydraulic cylinder can be fixedly connected with the part of the umbilical rod 2 close to the rotating shaft 11, and the other end of the hydraulic cylinder is arranged on a fixing piece on the ground. In addition, the follow-up telescopic length of the hydraulic oil cylinder is ensured to meet the leveling operation of the erecting arm 1, and the phenomenon that the erecting arm 1 falls after pulling the umbilical rod 2 when leveling in advance (at the moment, the hydraulic oil cylinder is in a follow-up state) is avoided.
In addition, when the erecting arm 1 is in a horizontal state, a fixing member provided in a transmitting field may be positioned below a portion of the erecting arm 1 near the rotating shaft 11, so that the other end of the hydraulic cylinder may be fixedly connected to the fixing member after passing through the erecting arm 1.
