摘   要

     本設計主要是帶式輸送機全自動液壓張緊裝置的設計。它是在吸收國、內外輸送機張緊技術的基礎上，根據國內帶式輸送機的運行特點及要求研制的。它采用比例控制技術及可靠性較高的可編程控制技術，可以對張緊力進行多點控制，根據不同工作情況隨時調節張緊力的大小。能最大程度的延長皮帶的壽命，大大節約了成本。在設計中，用一個動滑輪使液壓缸的行程減少了一半，避免使用行程較長的液壓缸，減少了制造液壓缸的難度。同時，系統中增加了若干個蓄能器，可以最大限度的吸收液壓沖擊，減小對皮帶的沖擊力提高膠帶的使用壽命。

Abstract

This design is mainly about full automatic hydraulic tension station for belt conveyer. It is designed on the foundation of opening technology in and outside, according to the domestic operation characteristic of belt conveyer and requirement. The equipment is also made on domestic belt-type conveyer movement characteristic and requestment. It uses the proportional control technology and the reliable higher programmable control technology, It may carry on the multi-spots control to strict the strength, adjusts pressing the strength size as necessary according to the different working condition.It can be the greatest degree lengthen the leather belt the life, greatly saved the cost. In the design, It causes the hydraulic cylinder with a movable pulley the stroke to reduce one half, and avoides using a stroke longer hydraulic cylinder.In this way,it reduces difficulty of  the hydraulic cylinder’s produce. At the same time, it increases certain accumulators in the system, and limits absorption hydraulic pressure impact,which reduces the leather belt impulse and enhances the adhesive tape’s life.

Key words: Belt-type conveyer, full automatic hydraulic tension station , proportional control, programmable control
