Description

通用型超静定液压支架  Universal type static static hydraulic support 技术领域Technical field

本发明涉及一种通用型超静定液压支架,尤其适用于煤矿井下采煤工作面的顶板支护,也适用于其它需要支护的场合。 The invention relates to a general-purpose statically indeterminate hydraulic support, which is especially suitable for roof support of coal mining face under coal mine, and is also suitable for other occasions requiring support.

背景技术Background technique

矿山支护设备是煤矿井下必不可少的设备之一。煤矿中使用的支护设备主要有四连杆机构的液压支架,也称四连杆液压支架,四连杆液压支架顶梁上、下的运动轨迹为一条双钮线,具体见煤炭工业出版社于1993年出版的《煤矿支护手册》第五篇第三章第三节内容和中国矿业大学出版社于2010年出版的“十一五”高等学校国家规划教材《矿山机械》一书中关于支护设备内容。四连杆液压支架起始于上世纪50年代,60年代技术进入成熟阶段,70年代末开始引入我国煤矿行业。四连杆液压支架存在的问题:一:由于其顶梁为一双钮线运动轨迹,每次使用时要进行一对一重新设计,并进行样架的试制和性能检测,通过检测合格后,才能取得安标证书,最后才能进行液压支架的生产制造,这样一个循环过程,少则半年,多则一年以上才能把设备交给煤矿使用,效率相当低下;二:由于四连杆液压支架的结构特点,其无法实现模块化设计,只能进行一对一单套设计和生产,设计工作量繁重,生产周期长,劳动强度大,生产成本高,中间环节的附加成本更高,严重影响了我国液压支架的推广速度和推广使用面。三:由于四连杆液压支架必须进行一对一单套设计和生产制造,给模块化、标准化、系列化、集成化生产带来很大的困难,无法进行零部件的规模化生产,更不可能进行集成化装配。因此,基于现有四连杆液压支架的问题,改变现有液压支架的技术原理和技术结构,具有重要的现实意义和历史意义。 Mine support equipment is one of the essential equipment in coal mines. The supporting equipment used in the coal mine mainly has the hydraulic support of the four-bar linkage mechanism, also called the four-link hydraulic support. The movement track of the top and bottom of the four-link hydraulic support top beam is a double button line. For details, see Coal Industry Press. The third section of the third chapter of the "Coal Mine Support Manual" published in 1993 and the "Eleventh Five-Year" College National Planning Textbook "Mining Machinery" published by China University of Mining and Technology Press in 2010 Support equipment content. The four-link hydraulic support started in the 1950s. In the 1960s, the technology entered a mature stage, and in the late 1970s, it began to introduce China's coal industry. Problems with the four-link hydraulic support: First, because the top beam is a double-button movement track, one-to-one redesign should be carried out each time, and the prototype and performance test of the sample rack can be carried out. Obtaining the safety standard certificate, and finally the production of the hydraulic support, so that a cycle of less than half a year, more than one year to hand the equipment to the coal mine, the efficiency is quite low; Second: due to the structure of the four-link hydraulic support Features, it can not achieve modular design, can only carry out one-to-one single set design and production, design workload is heavy, long production cycle, labor intensity, high production cost, higher cost of intermediate links, seriously affecting China The promotion speed and promotion of hydraulic brackets. Three: Because the four-link hydraulic support must be designed and manufactured one-to-one, it brings great difficulties to modularization, standardization, serialization and integrated production, and it is impossible to carry out large-scale production of parts, not to It is possible to perform an integrated assembly. Therefore, based on the existing four-link hydraulic support, changing the technical principle and technical structure of the existing hydraulic support has important practical and historical significance.
