【摘要】：鋼絲繩牽引帶式輸送機(jī)是超長距離帶式輸送機(jī)中重要的一種類型,更是普遍應(yīng)用于煤炭產(chǎn)業(yè)。其具有優(yōu)良的輸送性能:單機(jī)運(yùn)輸距離長和運(yùn)輸能力大;功率消耗少;運(yùn)行平穩(wěn);傾斜、水平場(chǎng)合均適用;可在水平面內(nèi)轉(zhuǎn)彎以及便于實(shí)現(xiàn)自動(dòng)化和環(huán)保。自1965年第一臺(tái)GD型鋼絲繩牽引帶式輸送機(jī)在我國問世,距今已有50多年的歷史,然而近些年GD型鋼絲繩牽引帶式輸送機(jī)的發(fā)展停滯不前,部分使用單位已將其淘汰或者替換,但其在超長距離輸送上仍具有一定存在價(jià)值,故急需對(duì)其進(jìn)行優(yōu)化和改進(jìn)。本文從設(shè)計(jì)、制造和使用方面指出了其缺陷,針對(duì)其有別于通用帶式輸送機(jī)的獨(dú)特部件提出了優(yōu)化改進(jìn)方案:改進(jìn)輸送帶使其不易脫槽;分析牽引鋼絲繩扭轉(zhuǎn)打滑機(jī)理,提出扭轉(zhuǎn)打滑導(dǎo)致快速斷繩的思想;采用防爆交流變頻調(diào)速技術(shù)替代直流調(diào)速技術(shù);為GD型鋼絲繩牽引帶式輸送機(jī)加設(shè)防倒轉(zhuǎn)裝置系統(tǒng),其核心部件是雙楔半自動(dòng)卡繩器,運(yùn)用三維建模軟件Solidworks建立雙楔半自動(dòng)卡繩器的三維實(shí)體模型,運(yùn)用有限元分析軟件ANSYS對(duì)卡繩器進(jìn)行動(dòng)力學(xué)分析,再利用ANSYS后處理軟件對(duì)其進(jìn)行瞬態(tài)動(dòng)力學(xué)分析,以證明防倒轉(zhuǎn)裝置有一定的可行性和發(fā)展。通過優(yōu)化改進(jìn)方案,可以改進(jìn)目前還在使用的GD型鋼絲繩牽引帶式輸送機(jī),在提高其適用性、可靠性和經(jīng)濟(jì)性基礎(chǔ)上,使其在以后長距離輸送上能有進(jìn)一步的發(fā)展和利用。
[Abstract]:Wire rope traction belt conveyor is an important type of super long distance belt conveyor and is widely used in coal industry. It has excellent transportation performance: long distance and large transportation capacity; less power consumption; smooth operation; inclined, horizontal applications; can turn in the horizontal plane and easy to achieve automation and environmental protection. It has been more than 50 years since the first GD type wire rope traction belt conveyor was introduced in China in 1965. However, in recent years, the development of GD type wire rope traction belt conveyor has stagnated, and some units have eliminated or replaced it. But it still has some value in long distance transportation, so it is urgent to optimize and improve it. In this paper, the defects in design, manufacture and application are pointed out, and the optimization and improvement scheme is put forward for the special parts different from the general belt conveyor: to improve the conveyor belt so that it is not easy to take off the groove, and to analyze the mechanism of torsion and slip of the traction wire rope. The idea of fast rope breakage caused by torsion slip is put forward, the technology of anti-explosion AC frequency conversion speed regulation is adopted instead of DC speed regulation technology, and the system of anti-inversion device for GD type steel wire rope traction belt conveyer is added, the core component of which is double wedge semi-automatic clamp rope, The 3D solid model of the twin-wedge semi-automatic rope clamp is established by using the three-dimensional modeling software Solidworks, the dynamic analysis of the rope clip is carried out by using the finite element analysis software ANSYS, and the transient dynamic analysis is carried out by using the ANSYS post-processing software. In order to prove the anti-inversion device has certain feasibility and development. By optimizing the improvement scheme, we can improve the GD type wire rope traction belt conveyor which is still in use at present. On the basis of improving its applicability, reliability and economy, it can be further developed and used in long distance transportation in the future.
