【摘要】：科學(xué)技術(shù)在不斷發(fā)展,其應(yīng)用領(lǐng)域也在不斷的擴(kuò)大,在煤礦行業(yè)上的應(yīng)用體現(xiàn)在礦井的立井提升系統(tǒng)中。罐道、罐道梁、滾輪罐耳和提升容器作為立井提升系統(tǒng)的重要組成部分,其安全性能和使用壽命也在不斷提高。立井提升的作用是人員安全的升降、煤炭的運(yùn)輸和機(jī)器設(shè)備的檢修,當(dāng)提升系統(tǒng)中任何一個(gè)設(shè)備在正常運(yùn)行中發(fā)生故障,這將直接影響煤礦的生產(chǎn)和經(jīng)濟(jì)效益,重則可能造成人員傷亡。目前立井提升系統(tǒng)朝著安全、高效的方向發(fā)展,隨著提升速度的提高和一次提升量增加,對(duì)滾輪罐耳的力學(xué)性能要求也越來越高。滾輪罐耳作為立井提升系統(tǒng)的導(dǎo)向裝置,其力學(xué)性能對(duì)立井提升系統(tǒng)有重要影響,當(dāng)其產(chǎn)生故障時(shí)會(huì)影響到罐道和罐籠的振動(dòng)行為,也會(huì)誘發(fā)整個(gè)系統(tǒng)產(chǎn)生故障,尤其在高速運(yùn)行下更為顯著,最終將破壞礦井的安全運(yùn)行。因此,為了滿足立井提升系統(tǒng)安全、高效的需要,進(jìn)行滾輪罐耳的剛度性能的研究十分必要。本文針對(duì)滾輪罐耳,分別采用結(jié)構(gòu)性能分析、剛度性能分析、仿真模擬和實(shí)驗(yàn)測(cè)試四種方法,在不同負(fù)載下的剛度性能進(jìn)行了分析研究。主要研究工作如下:(1)闡述了立井提升系統(tǒng)、滾輪罐耳的結(jié)構(gòu)特點(diǎn)、不同滾輪罐耳的性能分析和滾輪罐耳的發(fā)展方向。(2)根據(jù)滾輪在外載作用下的變形情況,利用Hertz理論推導(dǎo)了滾輪與罐道之間力學(xué)性能。在外載的作用下,作用力通過支架傳遞到緩沖器上,根據(jù)碟形彈簧的特點(diǎn)得到緩沖器的變形情況。(3)基于ADAMS運(yùn)動(dòng)仿真,對(duì)滾輪罐耳模型進(jìn)行仿真分析,探討了滾輪罐耳在承受徑向載荷時(shí),滾輪和緩沖器的位移變化分析,滾輪罐耳的剛度隨外載的變化規(guī)律。(4)搭建了滾輪罐耳靜態(tài)剛度測(cè)試試驗(yàn)臺(tái),介紹實(shí)驗(yàn)臺(tái)的組成部分,以及各組成部分結(jié)構(gòu)設(shè)計(jì)。(5)進(jìn)行了滾輪罐耳的徑向靜剛度測(cè)試,得到剛度特征曲線。同時(shí)測(cè)試結(jié)果和仿真結(jié)果進(jìn)行了對(duì)比分析,在趨勢(shì)上得到較好的一致性,通過多次實(shí)驗(yàn)對(duì)比,驗(yàn)證了測(cè)試方法良好的重復(fù)性。深入了解滾輪罐耳的剛度性能,獲得了滾輪罐耳的剛度參數(shù)。
[Abstract]:The application field of science and technology is constantly expanding, and its application field is constantly expanding. The application of the coal mine industry is embodied in the shaft lifting system of the mine. The tank Road, the tank beam, the roller tank ear and the lifting vessel are the important parts of the vertical shaft lifting system. The safety performance and the service life of the coal mine are also increasing. The function of the vertical shaft lifting is the human being. The safety and lift of the personnel, the transportation of coal and the maintenance of the machinery and equipment, when any one of the equipment in the lifting system fails in normal operation, this will directly affect the production and economic benefits of the coal mine, and it will cause casualties. At present, the vertical shaft hoisting system is developing in a safe and efficient direction, with the improvement of the speed of lifting and the other. The mechanical performance of roller tank ear is becoming higher and higher. As the guide device of the vertical shaft lifting system, the mechanical performance of the roller can have an important influence on the vertical shaft lifting system. When it has a failure, it will affect the vibration of the tank and the cage, and it will also cause the whole system to fail, especially at high speed. In order to satisfy the safety of the shaft hoisting system and the high efficiency, it is necessary to study the stiffness performance of the drum tank ear. In this paper, four methods, structural performance analysis, stiffness performance analysis, simulation simulation and experiment test, are used for the drum tank ear. The main research work is as follows. The main research work is as follows: (1) it describes the vertical shaft lifting system, the structure characteristics of the roller jar ear, the performance analysis of different roller canister ears and the development direction of the roller tank ear. (2) the mechanical properties between the roller and the tank channel are deduced according to the deformation of the roller under the loading of the outer load. Under the action of the external load, the force is transferred to the buffer through the support, and the deformation of the buffer is obtained according to the characteristics of the disc spring. (3) based on the simulation of the ADAMS motion, the model of the roller tank ear is simulated and analyzed. The analysis of the displacement of the roller and the bumper and the stiffness of the roller can be discussed. The changing law of the external load. (4) a test bench for the test of the static stiffness of the roller can be built. The composition of the test bench and the structure design of the components are introduced. (5) the radial static stiffness test of the drum of the roller can be tested and the characteristic curve of the stiffness is obtained. The test results are compared with the real results, and the trend is better. Conformance, the repeatability of the test method was verified by many experiments, and the stiffness performance of the roller tank ear was thoroughly understood, and the stiffness parameters of the roller tank ear were obtained.
