ZY32001434掩护式液压支架的设计(2)

Abstract

The design ZY3200/14/34 cover-powered support is mainly for Xing tai Mining Group, Xing tai 22313 face of the coal mine, and its surrounding equipment selection is for the design of a practical hydraulic support. It includes the following components:

Through the introduction of the entire mine geological conditions and the real situation face combined with the development of supports and classification of the hydraulic support for the selection and establish the basic technical parameters.

According to the structural components in the hydraulic support of the whole situation and bearing in the role of detail on top of the support beams, four-bar linkage, the side of the shield, base, post, and a variety of jack, and other parts of the structure design, and determine the over all structure of its size. Focus on doing a column structure, technical parameters that on the basis of carrying on the work of the resistance to the stability of the column, cylinder piston rod and the intensity of the check.

This paper introduces the characteristics of the support hydraulic system、the column、the basic control loop of a variety of jack system and their working principle, and selects the hydraulic pump station components and hydraulic lines.

Key words: cover-powered support the structural components the support hydraulic system
