安装和拆卸机械化综合机组的提升装置 莫斯科近郊煤炭科学研究所研制出一种安装和拆卸机械化综合机组的提升装置。所介绍的提升装置如下图所示。 提升装置包括下列各部分:底座的右部分1和左部分2,这两个部分用凹槽相互衔接并用液压千斤顶3连接一起,液压千斤顶的活塞杆刚性固定在底座的右部分上,而缸体固定在底座的左部分上;带定位销的制动器4,用定位销相对导向装置(中部槽)5横向固定底座的左右两部分;操纵台6、回转柱7,布置在底座的右部分上并用液压千斤顶8沿本身的轴转动;承重吊臂9,它
Installation and disassembly of lifting units for mechanized integrated units The Institute of Coal Science in the suburbs of Moscow has developed a lifting device for the installation and dismantling of mechanized integrated units. The lifting device introduced is shown below. The lifting device comprises the following parts: a right part 1 and a left part 2 of the base, which are mutually connected by a groove and are connected by a hydraulic jack 3; the piston rod of the hydraulic jack is rigidly fixed on the right part of the base; Fixed on the left part of the base; brake with a positioning pin 4, with the positioning pin relative to the guide (central groove) 5 laterally fixed base left and right parts; console 6, column 7, arranged on the right part of the base and use Hydraulic jack 8 along its own axis of rotation; load-bearing boom 9, it
