Description
本发明涉及矿山设备领域，具体涉及一种新型固定式矿用液压起吊装置。The invention relates to the field of mining equipment, in particular to a new type of fixed hydraulic lifting device for mines.
作为现代化综采生产的主要设备的液压支架，其发挥的作用非常突出，目前我国大部分煤矿都需要在地面将支架解体才能下井，然后在井下硐室再进行组装。但受提升罐笼尺寸的限制，以及煤矿井下硐室条件有限，在井下安装起吊组装存在很大的局限性。随着液压支架使用的材料越来越好，在井下服务的工作时间也越来越久，部分煤矿选择液压支架不升井直接在井下转面使用，这就要求煤矿井下能提供一个永久或者半永久的组装硐室，能实现对液压支架的修理与组装。As the main equipment of modern comprehensive mining production, hydraulic supports play a very prominent role. At present, most coal mines in our country need to disassemble the supports on the ground before they can go down, and then assemble them in underground chambers. However, due to the limitation of the size of the lifting cage and the limited conditions of the underground chamber of the coal mine, the installation of lifting and assembly in the underground has great limitations. As the materials used for hydraulic supports are getting better and better, and the working hours of underground services are getting longer and longer, some coal mines choose to use hydraulic supports directly at the turning surface without raising the well. This requires the underground coal mine to provide a permanent or semi-permanent assembly. The chamber can realize the repair and assembly of the hydraulic support.

In one of the pallets, such as the first hoisting pallet 9.1 Place 10.1 the parts to be assembled on .1, and place the lifting parts 10.2 on the second hoisting pallet 9.2.1.
当把第二吊装板车9.2.1上的起吊部件10.2吊起与第一吊装板车9.1.1上的待组装部件10.1组装时共有如下的步骤：When hoisting the lifting component 10.2 on the second hoisting pallet truck 9.2.1 and assembling the to-be-assembled component 10.1 on the first hoisting pallet truck 9.1.1, there are the following steps:
步骤一、四根拉线分别固定住起吊部件10.2的四个位置，第一起吊组件7和第二起吊组件8工作，四根拉线把起吊部件10.2水平吊起； Step 1. The four cables respectively fix the four positions of the lifting component 10.2, the first lifting component 7 and the second lifting component 8 work, and the four cables hoist the lifting component 10.2 horizontally;
步骤二、再让平移液压伸缩杆5把起吊部件10.2移动至待组装部件10.1上方；Step 2: Let the translational hydraulic telescopic rod 5 move the lifting component 10.2 to the top of the component to be assembled 10.1;
