摘要作为能源需求大国，实现我国煤炭行业的突破和发展，提高煤炭资源的产出，需要依靠 综采机械。在采煤行业大力推广综采机械，不仅能够加速煤炭产出，更能节省大量的人力资 源消耗，并能够加速我国采煤行业的现代化建设速度。在采煤过程中，不同采煤机械的合理 使用，会使得我国煤炭开采量大幅度提高，并可以节省大量的人力成本，促使煤炭价格降低， 加速我国现代化建设。在综采煤机械中，作为提供安全工作环境的液压支架，发挥着至关重 要的作用。因此，对液压支架的研究尤为重要。72692

液压支架的设计，要在保证足够的支护强度的基础上，尽可能的提供便捷的操作以及灵 活的移动。其中，四连杆机构的设计至关重要，合理的四连杆机构是保证液压支架达到预期 采高的前提条件。掩护梁、立柱等保护性装置，为一个安全的工作环境提供各种保障。

在四柱支撑掩护式液压支架的整体设计中，各组件支护强度的校核以及四连杆机构的设 计是本设计的侧重点。同时，液压支架的构造、工作原理等内容都会在本文中介绍。

Four-column support covering hydraulic supporter

Abstract As the energy needs of the country, China should rely on the mechanize to improve the coal output and realize the coal industry breakthrough and development。 China should promote the fully mechanized in the coal mining industry。 It can help us save a lot of manpower resource consumption and accelerate the speed of coal mining industry。 In the rational use of different coal mining machinery, will make the coal production increased greatly and save a lot of manpower cost, promoting coal prices, accelerating the modernization of our country。 In the comprehensive mechanization of coal mining, as to provide safe working conditions of hydraulic support, play a crucial role。 Therefore, research essential for hydraulic support。

The design of hydraulic support, to ensure enough supporting strength on the basis, as far as possible to provide convenient operation and flexible movement。 Among them, essential to the design of four bar linkage mechanism, reasonable four-bar linkage is to ensure that the prerequisite for mining height hydraulic support to achieve。 Shield beam, column, and other protective device, a safe working environment provides all kinds of security。

In four post support shield type hydraulic support the design, each component branch support strength check and four link mechanism design is the design emphasis。 At the same time, hydraulic support structure and working principle are introduced in this paper。

Key Words: hydraulic support; column; four link mechanism; support shield type
