我国进口的几千台D80A-12型推土机大多已工作了10000小时以上,机械技术性能显著下降,需及时大修。该机底盘部分的紧配合件加工精度高、配合紧度大,拆装费力,且拆装空间狭窄,有些部件还要用压力值来控制安装位置。目前,多数单位不能对底盘进行彻底解体检修,仍采用大锤打等笨重的拆装方式,其质量差,劳动强度大,效率低,常损坏零件。为此,我们研制一套专用液压拆装工具,经使用能迅速可靠地完成D80推土机底盘的拆装工作,解决了上述问题。
Most of the thousands of D80A-12 bulldozers imported from China have worked for more than 10,000 hours, and their mechanical performance has dropped significantly. Major overhauls are needed. The close-fitting parts of the chassis part of the machine have high processing precision, large matching tightness, and laborious dismantling, and the space for dismantling and installation is narrow, and some parts also need to use pressure values to control the installation position. At present, most units cannot perform thorough dismantling and overhaul of the chassis, and still use heavy hammers and other heavy and dismantling methods. Their poor quality, high labor intensity, and low efficiency often result in damage to parts. For this purpose, we have developed a special hydraulic assembly and disassembly tool that can quickly and reliably complete the disassembly and assembly of the chassis of the D80 bulldozer and solve the above problems.
