【摘要】：皮帶運輸機是連續(xù)運輸傳送機械中的一種主要設備,應用行業(yè)非常廣泛,同時也普遍存在著一些問題,這些問題影響著設備運行壽命、設備工作效率甚至造成安全隱患。譬如皮帶跑偏,皮帶跑偏會導致皮帶側邊加速磨損,甚至造成整條皮帶斷裂,因此如何解決“跑偏”問題從而讓皮帶運輸機高效安全地運行至關重要。本次畢業(yè)論文是針對皮帶運輸機在運行過程中出現(xiàn)的跑偏現(xiàn)象而進行的研究探討。本文首先簡要分析了皮帶運輸機中存在的跑偏現(xiàn)象、跑偏原因及跑偏所造成的影響,接著對皮帶運輸機的概況及國內外皮帶運輸機的發(fā)展狀況進行了概述,并解析比較了國內與國外皮帶運輸機技術性能上的差距。然后較為詳細地從多個角度分析了皮帶之所以發(fā)生跑偏的原因。皮帶跑偏的原因多種多樣,但最根本的原因在于驅動滾筒及張緊滾筒之間皮帶兩側張力不均勻,使得皮帶兩側對滾筒的壓力不一致。根據(jù)跑偏原因本文提出一些改進的措施與方法,最后分別從小型皮帶運輸機和大型皮帶運輸機兩個方面著手進行糾偏分析。小型皮帶運輸機承載小,運輸距離短,糾偏方法較為簡單,主要從力學的角度上進行糾偏分析。譬如,設計鼓形滾筒,使?jié)L筒對皮帶保持一定的自動對中性能；滾筒兩側安裝隨動式斜坡?lián)醢?可對皮帶產生較為明顯的對中力,這些方法能夠有效地防止小型皮帶運輸機上的皮帶“跑偏”。而大型皮帶運輸機負載大,運輸距離長,且運行速度快,糾偏方法較為復雜困難,主要采用電子糾偏方式。本文通過在驅動滾筒一側安裝變頻電機來改變電機轉速,控制驅動滾筒的轉速,從而達到自動糾偏的目的。通過采取這些措施,能夠很好地起到預防糾正皮帶跑偏的作用,更有效地提高了皮帶運輸機的工作效率,同時保證了皮帶運輸機的安全運行。
[Abstract]:Belt conveyer is one of the main equipment in continuous transportation and conveyance machinery. It is widely used in many fields, and there are also some problems, which affect the service life of the equipment. The working efficiency of the equipment may even cause safety problems. For example, the belt deviation will lead to accelerated wear and tear on the side of the belt, and even cause the whole belt to break. Therefore, how to solve the problem of "running deviation" so as to make the belt conveyor run efficiently and safely is very important. This thesis is a study on the phenomenon of running deviation of belt conveyor in the course of operation. Firstly, the phenomenon of running deviation in belt conveyer is analyzed briefly. Secondly, the general situation of belt conveyor and the development of belt conveyor at home and abroad are summarized. The differences between domestic and foreign belt conveyors in technical performance are analyzed and compared. Then, the causes of belt deviation are analyzed in detail from several angles. There are many reasons for belt deviation. However, the most fundamental reason is that the tension on both sides of the belt is not uniform between the driving drum and the tensioning drum, which makes the pressure on both sides of the belt inconsistent. According to the reasons of running deviation, this paper puts forward some improved measures and methods. Finally, the deviation correction analysis is carried out from two aspects of small belt conveyor and large belt conveyor. The small belt conveyer has small load, short transportation distance, and the method of rectifying deviation is relatively simple. For example, the drum drum is designed to maintain a certain automatic alignment performance to the belt, and the following slope baffles are installed on both sides of the drum, which can produce obvious counterforce on the belt. These methods can effectively prevent the belt "deviation" on the small belt conveyer. However, the large belt conveyer has the advantages of large load, long distance and high speed, so it is difficult to correct the deviation. In this paper, the frequency conversion motor is installed on the side of the driving drum to change the motor speed and control the rotational speed of the driving drum, so as to achieve the purpose of automatic correction. It can prevent and correct belt deviation, improve the efficiency of belt conveyor, and ensure the safe operation of belt conveyor.
