缠绕式双卷筒提升机

摘　要

单绳缠绕式矿井提升机的工作原理：钢丝绳的一端用钢丝绳夹持固定在卷筒幅板上，另一端经卷筒的缠绕后，通过井架天轮悬挂提升容器。这样，利用主轴旋转方式的不同，将钢丝绳缠绕上或放松，以完成提升或下降容器的工作。

主轴装置是单绳缠绕式矿井提升机的主要工作机构，它的作用是： ①缠绕提升机钢丝绳；②承受各种正常载荷(包括固定载荷和工作载荷)；③承受各种积极情况所造成的非常载荷。在非常载荷作用下，主轴装置部分不应有残余变形。单绳缠绕式矿井提升机的主轴装置是其核心部件，要求我们应认真设计，精心制造，这对于确保矿井提升机安全可靠运行，预防和杜绝故障及事故的发生，也具有十分重要的意义。

本设计根据生产实际和预选的数据，以提升机的配套设备为核心，经过科学的计算和分析，设计、选择了一套矿井提升机的传动系统设备，并采用了光电测速传感器作为深度指示系统的数据采集装置，实现了从机械控制到数电控制的转变，同时为提升机控制系统的技术改造奠定了基础。

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
