槽形托輥帶式輸送機(jī)設(shè)計(jì)

摘要：本文所設(shè)計(jì)的是槽形托輥帶式輸送機(jī)，其設(shè)計(jì)要求為：輸送物料為原煤，輸送量：500 噸/小時(shí)，輸送長度：30 米,提升高度2.5米；堆積密度：900公斤/米3；物料在帶面上的動堆積角為300，輸送帶速：2米/秒，上托輥槽形布置。設(shè)計(jì)中，其整體是一個(gè)傾斜的狀態(tài)，上托輥都采用槽形布置；下（回程）托輥采用平行托輥。本輸送機(jī)為向上運(yùn)輸物料，其傾斜角為3.80<150，所以采用小傾角設(shè)計(jì)。在設(shè)計(jì)帶寬時(shí)，按照槽形布置來選擇計(jì)算。在尾架的選取方面，采用螺旋拉緊裝置尾架，使輸送帶能始終保持必要的張力。用Solidworks對連接軸進(jìn)行有限元分析，得出其一般工作時(shí)的性能狀態(tài)，并做出相應(yīng)的調(diào)整。
目前，帶式輸送機(jī)正朝著長距離，高速度，低摩擦的方向發(fā)展，近年來出現(xiàn)的氣墊式帶式輸送機(jī)就是其中的一個(gè)。在帶式輸送機(jī)的設(shè)計(jì)、制造以及應(yīng)用方面,目前我國與國外先進(jìn)水平相比仍有較大差距,國內(nèi)在設(shè)計(jì)制造帶式輸送機(jī)過程中存在著很多不足。

Abstract: What is designed in this paper is slotted roller belt conveyor, the design requirements are: transport of materials: coal, transport capacity: 500 tons / hour, transmission length: 30 meters, 2.5 meters high upgrade; Bulk Density: 900 kg / m 3; materials in the dynamic accumulation of the surface with angle is 30, conveyor speed: 2 m / s, on the trough roller arrangement. Design of a tilt the overall state of the idler trough arrangement used; under the (return) the use of parallel idler rollers. When the materials are transport up through the conveyor, the tilt angle is 3.80 <150, so take the use of small-angle design. As the selection of the tailstock, we take the use of Tailstock screw tensioning device so that the conveyor system can always maintain the necessary tension. And Solidworks is used to do the finite element analysis on the connecting axis, to meet the required strength.
Today, long distance, high speed, low friction is the direction of belt conveyor’s development. Air cushion belt conveyor is one of them. At present, we still fall far short of abroad advanced technology in design, manufacture and using. There are a lot of wastes in the design of belt conveyor.
