Device for installing erecting oil cylinder and rocket erecting system

Abstract

The invention provides a device for installing an erecting oil cylinder and a rocket erecting system. The device comprises a chassis, the chassis is fixed to the ground through a fixing piece, a lifting bracket is arranged on the chassis, and one end of the lifting bracket is hinged to the chassis 1 through a first hinged shaft seat. A lifting oil cylinder is arranged on the chassis, and the two ends of the lifting oil cylinder are connected with the chassis and the lifting bracket correspondingly and used for lifting the lifting bracket. A moving mechanism is arranged at the other end of the lifting bracket, an oil cylinder bracket is movably connected to the moving mechanism through a second hinged shaft seat, and the oil cylinder bracket is used for lifting the vertical oil cylinder. One end of the erecting oil cylinder is movably connected to a third hinged shaft base fixed to the ground, and the third hinged shaft base is located on the side, connected with the first hinged shaft base, of the lifting bracket. The device is easy to operate, transverse adjustment of the erecting oil cylinder can be achieved, and the connecting precision of the erecting oil cylinder is guaranteed. In addition, the device adopts automatic control, so that manpower is greatly saved, and the launching preparation time is shortened.

Description

technical field [0001] The invention relates to the technical field of rocket erecting racks, in particular to a device for installing an erecting oil cylinder and a rocket erecting system. Background technique [0002] In recent years, with the development of aerospace technology, especially the vigorous rise of commercial aerospace in recent years, a large-scale bundled liquid launch vehicle of our company adopts the "three flat and one vertical" test and launch mode, which is horizontal assembly, horizontal transfer, and horizontal testing. , The launch mode of vertical launch. This bundled liquid rocket is the rocket with the largest mass and size launched in the "three flat and one vertical" mode in China, so the matching erecting frame is also the largest erecting equipment in China. Based on the current domestic technology, large multi-stage hydraulic cylinders must be used as the actuators for erection to complete the vertical erection of the erection frame with the...

AI Technical Summary

Problems solved by technology

Due to the limited installation space of the vertical frame, there are many inconveniences in hoisting, and the hoisting accuracy is poor. The lower hinge point of the oil cylinder is connected by a joint bearing, and there is a certain amount of sloshing. It is not suitable for the precise shaft installation of the upper hinge point of the vertical oil cylinder. operation, and there is a certain risk of damage to the erection cylinder
