The electric flat carriage comprises a flat carriage frame, a motor, a speed reducer, a driving wheel set, a drivenwheel set and a electric storage device providing electric energy for the motor, and the motor, the speed reducer, the driving wheel set, the driven wheel set and the electric storage device are arranged at the bottom of the flat carriage; the motor is in transmission connection with the driving wheel set through the speed reducer; the track mechanism comprises a pair of parallel first tracks anda pair of parallel second tracks, and the first tracks and the second tracks are arranged on the ground; the first tracks are perpendicular to the second tracks; the transfer platform mechanism comprises a platform frame and a rotary disk body arranged in a table top of the platform frame. Two sets of transition tracks are in docking connection with the first tracks and the second tracks are arranged on the platform frame. The rotary disk body is provided with a set of rotary disk tracks. The bottom of the rotary disk body is provided with a rotating assembly. The vertical airspace engine track switching system is powered through electric energy and is eco-friendly and safe. Moreover, the flat carriage can conduct steering more easily.

Description

technical field [0001] The invention relates to the field of aerospace manufacturing, in particular to a vertical aerospace engine track system. Background technique [0002] With the development of the aerospace industry, large spacecraft will become the focus of my country's future aerospace development. Due to functional requirements, the existing large spacecraft have more and more instruments and equipment, which poses challenges to the ground assembly. For a vertical aerospace engine, its weight can reach tens of tons, which requires very high requirements for the transportation channel when each station is switched during the final assembly process.

[0003] The rail flat car is a kind of railed in-plant transportation vehicle, which is specially used to solve the product transportation between the spans in the factory. It is often used for the transfer of vertical aerospace engines, but the current rail flat cars are all fueled by fuel The engine provides the power source. This method not only consumes resources and has poor environmental protection effect, but also has certain safety hazards. Because the rail flat car generally encounters the situation of changing tracks during operation, and the traditional rail flat car mostly uses its own Turning to realize the track transition, for example, when passing through two sets of vertically crossed tracks, the wheels at the bottom of the flat car are adjusted to move from one set of tracks to another set of tracks. Due to the heavy weight of the vertical aerospace engine, the friction force between the wheel and the track of the flat car is very large, which makes it easier to generate sparks from the friction between the wheel and the track when turning. Rail flat cars pose a certain level of hidden danger, and the way the steering makes the wheels more prone to wear

At present, there is no better rail transfer system for the transportation of vertical aerospace engines, so it is necessary to design and manufacture such a system
