Description

Movable combined type transmitting table structure

Technical Field

The utility model relates to the technical field of rocket launching platforms, in particular to a movable combined launching platform structure.

Background

Before the rocket is launched, the launching pad is used for vertically supporting and fixing the rocket, the verticality adjustment of the rocket body is completed, the rocket has various configurations of serial connection and parallel connection, the diameters of the rockets are different and are divided into heavy rockets, large rockets, medium rockets and small rockets, the requirements of the rockets with different diameters on the launching pad are different, the structures of the launching pad are different, the small rockets are easy to realize maneuvering launching, the large rockets and the heavy rockets are launched at a fixed station generally, and the medium rockets are launched at the fixed station mostly. The launch pad is typically comprised of a launch pad structure, a hydraulic system, and an electrical system.

The rocket launching pad structure is generally composed of a pad body, supporting legs, supporting arms and a wind-proof device, wherein the conventional launching pad body is generally square or round, and the middle space is used for avoiding a rocket engine nozzle. The number of supporting arms is usually 4, the bottom of the supporting arms is arranged on the table surface of the launching table, and the extending part is provided with a longitudinal through hole for installing a wind-proof device. The supporting disk of the wind-proof device directly bears rocket feet, and a device for pressing the rocket feet is arranged for fixing the rocket. The number of the supporting legs is usually 4, and the supporting legs are supported below the table body and correspond to the supporting arm positions.

The medium-sized and large-sized rockets are usually launched at a fixed station, a diversion trench is excavated at the launching station, a supporting leg foundation of the launching pad is poured, and a supporting leg disc of the supporting leg is fixed on the foundation by using foundation bolts. The launching pad is transported to the launching station from a production factory, installed and debugged once, maintained according to technical conditions after each rocket launching task is executed, and can be used for multiple times at a fixed station. Except for a return to the factory overhaul, generally no longer moves. The small rocket launching mode is flexible, the launching pad can be a vehicle-mounted launching pad or a simple launching pad placed on a launching pad, and the small rocket launching pad is generally matched with a deflector to be used without excavating a diversion trench.

For medium-sized and large-sized launching tables, the supporting legs are generally required to be disassembled, the table body and the supporting legs are transported on the road respectively, and the table body may exceed the limit of road transportation.

The traditional medium-sized transmitting table body mostly adopts an integral casting process, and has good integral rigidity. The casting cost of the table body is high because the launching table is generally single piece or small batch. For more than ten years, the platform structure adopting the welding process is gradually applied and popularized.

The middle rocket adopts a three-level test launch mode (horizontal transfer, horizontal assembly and horizontal test), and is wholly erected. The structure has no fixed transmitting station, no transmitting service tower and no diversion trench, and only one transmitting field apron can be used, and the structure of the transmitting station has the appearance length of 7m, the width of 6m and the height of 5m. For medium rocket launching pad, it is necessary to install and debug on site on the launching pad. After the rocket launching task is executed once, the launching pad structure is required to be disassembled, the highway is transported to other launching stations, and the rocket launching pad is installed and debugged again. Through maintenance, move between different launching stations, use for multiple times.

In the practical application process, the inventor finds that at least the following problems exist in the prior art: the road transportation is limited by the width of the road and the height of the bridge, the length, the width and the height of the product are limited, the transportation cost is increased sharply along with the increase of the size of the product, even the road transportation cannot be realized, and the launching pad is not provided with fixed hoisting equipment such as a truss crane, a gantry crane and the like due to the limitation of the launching pad hoisting equipment, and the launching pad can only be disassembled and assembled by using a lorry crane. Because it needs supporting mounting tool to require higher, causes the dismouting operation convenience relatively poor, can greatly increased the cost of transportation and equipment simultaneously, so the practicality is restricted.
