Vertical highway transport vehicle

Abstract

The invention discloses a vertical highway transport vehicle and relates to a highway transport vehicle used for transporting an aerospace vehicle. The vertical highway transport vehicle can meet the requirements for the high stability, the high smoothness and the high maneuverability of products in various states in the vertical transportation process. The vertical highway transport vehicle comprises a vehicle frame assembly (1) and a traction mechanism (2). The vehicle frame assembly comprises a vehicle frame body and widened beams (3). The vehicle frame body comprises a front bearing face (101), a middle bearing face (102) and a rear bearing face (103) which are sequentially and fixedly connected. The middle bearing face is lower than the front bearing face and the rear bearing face. The two sides of the middle bearing face are each provided with one widened beam. A front wheel set (4) and a rear wheel set (5) are installed below the front bearing face and the rear bearing face through slewing bearings respectively. Traction support lugs (7) are arranged on the front wheel set and the rear wheel set and used for connecting the traction mechanism.

Description

technical field [0001] The invention relates to the field of road transport vehicles, in particular to a road transport vehicle for transporting aerospace vehicles. Background technique [0002] Space vehicles include launch vehicles, spaceships, space shuttles, etc. Space vehicle road transport vehicles are used to transport vehicles from the technology test center to the launch center. At present, the United States, Europe and my country usually adopt the vertical transportation method for the fairing containing the payload. Due to the increasing structural size and mass of the product, the position of the center of mass is getting higher and higher, such as the CZ-3B launch vehicle. The maximum diameter of the satellite airtight container (with payload inside) is 4150mm, the height of the center of mass is 3100mm, the maximum diameter of the assembly is 4200mm, and the height of the center of mass is 2546mm. These parameters of ultra-wide and ultra-high position of the cen...

Problems solved by technology

At present, the United States, Europe and my country usually adopt the vertical transportation method for the fairing containing the payload. Due to the increasing structural size and mass of the product, the position of the center of mass is getting higher and higher, such as the CZ-3B launch vehicle. The maximum diameter of the satellite sealed container (with payload inside) reaches 4150mm, the height of the center of mass reaches 3100mm, the maximum diameter of the assembly reaches 4200mm, and the height of the center of mass reaches 2546mm. These ultra-wide and super-high position of the center of mass cause great difficulties for road transportation

Satellite airtight containers must be transported vertically. During the transition, two-way traction is required and a road vehicle must be manually pushed to align the hoisting position. Ordinary vehicles cannot meet the requirements for use.
