摘 要
普通帶式輸送機(jī)只能水平運(yùn)輸，但是由于地質(zhì)條件的限制，需要帶式輸送機(jī)能夠轉(zhuǎn)彎運(yùn)行針對(duì)這一問(wèn)題，對(duì)平面轉(zhuǎn)彎理論進(jìn)行了研究，以SDJ-150型帶式輸送機(jī)結(jié)構(gòu)為基礎(chǔ)，本設(shè)計(jì)采用使托輥具有安裝支撐角和構(gòu)成內(nèi)曲線抬高角措施，并對(duì)過(guò)渡段和轉(zhuǎn)彎段進(jìn)行合理設(shè)計(jì)，經(jīng)過(guò)計(jì)算SDJ-150型可伸縮帶式輸送機(jī)經(jīng)改造后可以實(shí)現(xiàn)平面轉(zhuǎn)彎運(yùn)行。通過(guò)對(duì)SDJ-150可伸縮帶式輸送機(jī)進(jìn)行的改造使其能夠?qū)崿F(xiàn)平面轉(zhuǎn)彎運(yùn)行，解決了在特殊地質(zhì)條件下，單臺(tái)帶式輸送機(jī)自然轉(zhuǎn)向問(wèn)題，同時(shí)減少了設(shè)備的數(shù)量、減少初期投資和減少巷道開(kāi)拓量，使運(yùn)輸系統(tǒng)變得簡(jiǎn)單便于維護(hù)，從而發(fā)揮了SDJ-150可伸縮帶式輸送機(jī)的優(yōu)點(diǎn)，滿(mǎn)足了高產(chǎn)高效的要求，同時(shí)也表明，普通帶式輸送機(jī)實(shí)現(xiàn)平面轉(zhuǎn)彎運(yùn)行是無(wú)轉(zhuǎn)載連續(xù)轉(zhuǎn)彎運(yùn)輸合理設(shè)計(jì)方案。

Abstract
The general level of the transport belt conveyor only, but due to geological conditions of the restrictions, the need for belt conveyor to turn operation of this issue, on the theory the plane turn on to SDJ-150-type structure based on the belt conveyor This design uses a roller to support the installation angle and composition of the elevation angle of measures and the transition, and of turning a reasonable design, calculated SDJ-150-retractable belt conveyor can be achieved through improved operational plane bend . Through the SDJ-150 retractable belt conveyor for the transformation to enable it to achieve plane turning operation, a solution in the special geological conditions, natural belt conveyor to a single issue, while reducing the number of the equipment, reducing the initial investment And reduce the amount of roadway open up so that the transport system for easy maintenance, which played a SDJ-150 retractable belt conveyor of the advantages of a high yield and high efficiency to meet the requirements, but also show that the realization of the general belt conveyor plane turning operation No change is reproduced for the reasonable design.
