Abstract

The invention relates to a three-stage erecting system and belongs to the technical field of erecting. The three-stage erecting system solves the problems that the control precision is low, the stability is poor and an erecting arm is prone to exceeding the eversion point in the prior art. The three-stage erecting system comprises an oil supply unit, a three-stage hydraulic cylinder, a main powerbranch and three auxiliary power branches; a high pressure hydraulic cylinder communicates with the oil supply unit through the main power branch and a high pressure auxiliary power branches; stretching of the high pressure hydraulic cylinder and a medium pressure hydraulic cylinder is firstly driven by corresponding auxiliary power branches, and then the main power branch is switched when closingto the maximum range of the three-stage hydraulic cylinder; stretching of a low pressure hydraulic cylinder is firstly driven by corresponding auxiliary power branch, the main power branch is switched to push when an erecting angle is close to 90 degrees, so that the erecting angle of the erecting arm reaches 90 degrees to complete the erecting. The three-stage erecting system is used for the erecting process.

Description

technical field [0001] The invention relates to an erecting technology, in particular to a three-stage erecting system in which multiple accumulators assist three-stage cylinders in sections. Background technique [0002] The erection time of large-scale erection equipment such as missile launching vehicles affects the rapid response capability of missiles, and then affects the survivability of missiles. [0003] In the prior art, the erecting system usually includes a single-rod hydraulic cylinder, a main power branch and an auxiliary power branch. The extension of the single-rod hydraulic cylinder is first pushed by the auxiliary power branch. At 90°, switch to the main power branch to push, so that the erecting angle of the erecting arm reaches 90°, and the erection is completed, thereby increasing the erection time of the erecting equipment. [0004] However, those skilled in the art have not recognized the deficiencies of the above-mentioned erecting system for a long ...
