Problems solved by technology

[0004] The traditional manual handling and installation method of the servo mechanism is only suitable for the installation of the small-sized and light-weight servo mechanism in a large space, which has certain limitations. At the same time, the manual handling process is complicated and risky
[0005] The new-generation launch vehicle uses a high-thrust liquid oxygen kerosene engine. The engine pipeline has a complex structure and a large volume, and the space in the rocket cabin is extremely tight.
The weight and volume of the servo mechanism supporting the new generation of launch vehicles have increased significantly, and manual handling is difficult and the safety is poor. At the same time, it is difficult for the servo mechanism to enter the rocket cabin through the 500mmX500mm window on the rocket cabin.
Therefore, the manual handling method used in the traditional servo mechanism installation cannot meet the installation requirements of the new generation launch vehicle servo mechanism

Embodiment 1

[0058] The lengths of the first sling 4 and the second sling 6 are 0.5 m and 0.8 m, respectively.

[0059] The first sling 4 is fixed at the position 2 / 5 of the left end of the hanging beam 1, that is, the distance from the fixed position of the first sling 4 to the left end of the hanging beam is 2 / 5 of the length of the hanging beam 1.

[0060] The suspension beam 1 is a cylindrical steel pipe with several through holes distributed, the length of the suspension beam 1 is 1.75 m, and the spacing of the through holes on the suspension beam 1 is 0.2 m. Two studs 2 at each end of the hanging beam 1.

[0061] The height of the boss at one end of the second clamp 12 and the depth of the groove at one end of the first clamp 11 are 18 mm, and the left-right gap after assembly is 0.2-0.5 mm.

[0062] The material of the hanging beam 1 and the clamp assembly 7 is stainless steel.

Abstract

The invention relates to an installation device and an installation method of a servo mechanism in a compact space of a rocket compartment, the device includes a hanging beam, a hoisting device, a clamp assembly and a trolley, wherein the hanging beam is installed on the engine frame in the rocket compartment , one end of the hoisting device is connected to the hanging beam, and the hoisting device can move along the hoisting beam, the other end of the hoisting device is connected to the clamp assembly, the clamp assembly is installed on the servo mechanism, and the servo mechanism is placed on the cart; the clamp assembly includes The first clamp, the second clamp, the lifting lug, the first connection device and the second connection device, the device is simple to operate, easy to install, effectively avoids the risk of manual handling, improves efficiency and reduces labor costs, and can meet compact spaces It is suitable for the installation of servo mechanisms in the country, and is also suitable for the installation of large-volume and high-quality servo mechanisms. In addition, the installation process is more standardized, which significantly improves the installation reliability and safety.

Description

Technical field [0001] The invention relates to a servo mechanism installation device and method, in particular to a servo mechanism installation device and an installation method in a compact space of a rocket cabin. Background technique [0002] With the continuous development of my country's aerospace technology, manned spaceflight and manned landing on the moon have an increasing demand for engine-level thrust. High-thrust engines have been used in the new generation of launch vehicles and are developed to achieve thrust vector control of high-thrust engines. The weight and volume of the high-power servo mechanism of the carrier rocket have been significantly increased. The maximum weight of the supporting servo mechanism of the active carrier rocket is about 55kg and the maximum length is about 1365mm; while the maximum weight of the supporting servo mechanism of my country's new-generation carrier rocket high-thrust engine is about 105Kg and the maximum length It is about 184...
