Embodiment 1

[0044] This embodiment provides a quick erecting method. It should be noted that, in order to clearly describe the quick erecting method, the structure of the quick erecting system is introduced first.

[0045] Quick erection systems such as figure 1 As shown, it includes oil supply unit, multi-stage hydraulic cylinder 1, main power branch and multiple auxiliary power branches connected in parallel; the oil inlet circuit of each hydraulic cylinder of multi-stage hydraulic cylinder 1 passes through the main power respectively. The branch and one of the auxiliary power branches are connected to the liquid outlet of the oil supply unit; the oil return circuit of the multi-stage hydraulic cylinder 1 is connected to the external oil tank; multiple auxiliary power branches can be divided into high-pressure auxiliary power branches, medium-pressure Auxiliary power branch and low-pressure auxiliary power branch, correspondingly, multi-stage hydraulic cylinder 1 can also be divided into ...

Abstract

The invention relates to a quick erection method, belongs to the technical field of erection, and solves the problems that in the erection method in the prior art, the control precision is low, the stability is poor, and the erection arm goes beyond the overturning point easily. The erection method comprises the following steps: during the erection process of the erection arm, each stage of hydraulic cylinder is pushed to extend through an auxiliary power branch, and the other stages of hydraulic cylinders, except the final stage of hydraulic cylinder, switch to a main power branch when reaching the maximum stroke; and the final stage of hydraulic cylinder switches to the main power branch to be pushed at the time the erection angle of the erection arm is close to 90 degrees, and the erection angle of the erection arm reaches 90 degrees to complete the erection. The quick erection method provided by the invention can be used for the erection process.

Description

technical field [0001] The invention relates to an erecting technology, in particular to a rapid erecting method for multi-stage hydraulic cylinders assisted by multiple accumulators. 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 time, an...
