A centering and ranging method for a multifunctional rocket docking vehicle

Abstract

The invention provides a method for centering and ranging a multifunctional rocket docking vehicle. The multifunctional rocket docking vehicle includes: a vehicle body and a monitoring device arranged on the vehicle body, and the vehicle body includes a bottom Frame and the adjustment assembly and the arrow body bracket arranged on the bottom frame; the monitoring device includes: a centering distance measuring device of the frame vehicle arranged on the arrow body bracket, and a quality measuring device arranged on the adjustment assembly device, and a vehicle safety protection early warning device arranged on the bottom frame. The invention can make the centering operation easier, the centering precision is higher, and the time is less; the measurement data is more accurate, and the time is less; the accidental injury to the operator caused by the carriage can be prevented; and the weighing of the rocket body can be simplified process and reduce the labor intensity of operators.

Description

technical field [0001] The invention relates to a docking vehicle, in particular to a centering and ranging method for a multifunctional rocket docking vehicle. Background technique [0002] At present, during the final assembly process of liquid launch vehicles in active service in China, the carriage on the track is used to carry out the docking work between the cabin and the storage tank. [0003] The traditional docking frame for final assembly has a simple structure and a single function, and only has the functions of rolling, lifting, and translation. During final assembly, docking carriages are usually used in pairs. When the rocket body is parked on the rack, the axis of the rocket body needs to be parallel to the ground, so as to ensure that the structure of the rocket body is well stressed. In order to achieve this purpose, the rocket body brackets of the two carriages supporting the rocket body need to be located at the same height. However, at the actual assem...

Problems solved by technology

[0005] Again, from the perspective of personal safety, the existing rocket docking vehicle also has certain hidden dangers, which may cause personal injury

In the production process of rockets in the past, when the operator pushed the carriage, there were accidents where the soles of the feet did not leave the track in time and were crushed by the wheels of the carriage.

However, this hidden danger has not been effectively resolved. Experienced operators will remind each other to avoid running wheels on the soles of the feet, but for inexperienced operators, they do not have such safety awareness, and the same safety accident often occurs in the happens again after some years

[0006] In addition, according to the rocket assembly process, usually after the docking of the rocket cabin and the storage tank is completed, it is often necessary to measure the mass characteristics of the rocket sub-stages, and the docking vehicle does not have the function of mass measurement, resulting in rockets being docked in stages. After completion, multiple hoistings are required to complete the work of mass measurement

The operation process of the measurement project is not only monotonous and cumbersome, but also takes a lot of time, and multiple hoisting operations will increase the probability of safety accidents for personnel and products
