【摘要】：隧道掘進(jìn)機(jī)以其安全、快速、經(jīng)濟(jì)、環(huán)保的優(yōu)勢廣泛應(yīng)用于地下隧道的掘進(jìn),其中液壓推進(jìn)系統(tǒng)在掘進(jìn)機(jī)上占有重要的地位,它控制著掘進(jìn)機(jī)整體向前掘進(jìn)。在惡劣的工況下,推進(jìn)油缸會(huì)受到非周期性的振動(dòng),以螺紋為連接方式的導(dǎo)向套在受到振動(dòng)之后容易發(fā)生松動(dòng),從而導(dǎo)致推進(jìn)油缸不能正常工作。針對這類情況,設(shè)計(jì)出一種新型導(dǎo)向套防松結(jié)構(gòu),并基于有限元軟件ANSYS Workbench進(jìn)行仿真分析,驗(yàn)證了設(shè)計(jì)的合理性,提高了掘進(jìn)機(jī)的安全性和可靠性。
[Abstract]:Tunnel tunneling machine is widely used in underground tunneling with its advantages of safety, speed, economy and environmental protection. Hydraulic propulsion system plays an important role in the tunneling machine, and it controls the overall heading forward of the tunneling machine. Under bad working conditions, the propulsion cylinder will be subjected to aperiodic vibration, and the guide sleeve with thread connection will easily become loose after vibration, which will lead to the failure of normal operation of the propulsion cylinder. In view of this kind of situation, a new type of guide sleeve anti-loosening structure is designed and simulated based on the finite element software ANSYS Workbench, which verifies the rationality of the design and improves the safety and reliability of the roadheader.
