纏繞式雙卷筒提升機

摘　要

單繩纏繞式礦井提升機的工作原理：鋼絲繩的一端用鋼絲繩夾持固定在卷筒幅板上，另一端經卷筒的纏繞后，通過井架天輪懸掛提升容器。這樣，利用主軸旋轉方式的不同，將鋼絲繩纏繞上或放松，以完成提升或下降容器的工作。

主軸裝置是單繩纏繞式礦井提升機的主要工作機構，它的作用是： ①纏繞提升機鋼絲繩；②承受各種正常載荷(包括固定載荷和工作載荷)；③承受各種積極情況所造成的非常載荷。在非常載荷作用下，主軸裝置部分不應有殘余變形。單繩纏繞式礦井提升機的主軸裝置是其核心部件，要求我們應認真設計，精心制造，這對于確保礦井提升機安全可靠運行，預防和杜絕故障及事故的發生，也具有十分重要的意義。

本設計根據生產實際和預選的數據，以提升機的配套設備為核心，經過科學的計算和分析，設計、選擇了一套礦井提升機的傳動系統設備，并采用了光電測速傳感器作為深度指示系統的數據采集裝置，實現了從機械控制到數電控制的轉變，同時為提升機控制系統的技術改造奠定了基礎。

ABSTRACT

What the principle of the single rope twines mine pit elevator is that: One end of the steel wire rope is fixed to Winding by the steel wire rope nip, another end after twined hangs and promotes the vessel by derrick wheel. In this way, we make use of the differences of the revolve way to twine or relax the steel wire rope so that to complete the vessel to step up or drop down.

Main axle is the core part of the mine elevator. Its functions are: ① the steel wire rope of twines the type mine pit elevator ; ② endure a kind of normal load( including fixed load and work load ); ③ endure the kinds of unusual load which is result from positive situation. Under the unusual load function, the part of the main axle equipment should not remain remaining distortion. It required us to be careful designing and manufacture when designing and manufacturing. Only in this way, we can prevent the occurrence of failures or accidents .Obviously, the possesses is very significance.

This design is on the basis of the data which are chosen by advance and actually, take the elevator supplementary equipment as the core, after the analysis and computation in science, has designed and chosen a set of the transmission system of the mine pits elevators, and used the electrical-light sensor as the equipment of the indicating system which to measure the amount of the depth of the tank. It enforced the change from the mechanically control to the numerical control, at the same time, has laid the foundation for improve the control system of the elevator.

KEY WORDS: elevator, main axle, brake, electrical-light measurement velocity sensor
