ZY3800/8.5/19薄煤层液压支架的研制
首发时间:2012-02-15
摘要:本文详细介绍了ZY3800/8.5/19型薄煤层液压支架的研制过程,给出了支架的主要技术参数,对支架的主要结构件及立柱、千斤顶进行了设计,计算得立柱及千斤顶的缸径、杆径及其行程。该支架采用pm32/vt简易电液控制系统作为其操作系统,实现了正常、高效地安全生产。支架大部分结构采用Q460高强度钢板,部分盖板采用Q550高强度钢板。结构件在焊前进行预热,焊接时采用富氩气体保护,焊后进行回火处理,这样可以提高焊接结构的使用可靠性及寿命。介绍了该支架设计的主要特点,ZY3800/8.5/19型液压支架具有广阔的应用前景。

Development of ZY3800/8.5/19 thin coal seam hydraulic support
Abstract:This text introduced the development of ZY3800/8.5/19 thin coal seam hydraulic supportses in detail and gave the main technique parameter of support, designed the main structure piece of support and signed pillar, jack , computed sign the urn of pillar and jack path, pole path and its route of travel.The support adopted the pm 32/vt simple electricity liquid control system as its operate system and carried out as usual, efficiently safe production.The support big parts of structure adopted Q460 high strength steel plate, and some cover planks adopted Q550 high strength steel plate.The structure piece goes forward to go to prepare heat in the Han, while welding adopted the rich argon gas body to protect, the Han juniors goes a fire processing once, passing to do these can raise the use credibility and life span of welding the structure like this.Introduced the main characteristics of the support's design, ZY 3800/8.5/19 hydraulic supports have the applied prospect of amplitude.
