立井提升系统是如何工作的？
Shaft lifting system is how to work?
立井普通罐笼提升。其中一个罐笼位于井底车场水平，另一个罐笼位于井口出车平台。提升钢丝绳与一端与罐笼相连，另一端绕过天轮，缠绕并固定在滚筒上，当电动机带动提升机滚筒旋转时，井下的罐笼上升。加一端的罐笼下降，使罐笼在井筒中沿罐道作上下往复运行，进行提升工作。
Ordinary shaft cage hoisting. One cage is located in the bottom level, another car is located in cage wellhead platform. Hoist wire rope with one end connected with the cage, the other end passes by the pulley, wound and fixed on the roller, when the motor drives the hoist drum rotates, the rise of underground cage. With the end of the cage down the cage up and down reciprocating operation in the wellbore along the tank, lifting work.

斜井的提升系统是如何工作的？
The inclined lifting system is how to work?
为目前使用较多的斜井串车提升系统，斜井串车提升用矿车做提升容器，钢丝绳的一端与若干个矿车组串车的连接，另一端绕过天轮缠绕并固定在提升机的滚筒上，滚筒旋转带动串车组在井筒中往复运动，进行提升工作。
At present, the use of more inclined shaft lifting train system, lifting lifting container for cars, connecting the wire rope end and a plurality of car series car, the other end around the sheave wound and fixed on the hoist drum, drum rotates to drive the string of vehicles in reciprocating motion in the wellbore, lifting work.
串车提升有单钩和双钩之分。按车场形式的不同，又分甩车场和平车场。单钩串车提升，可用于多水平提升，一般采用甩车场。平车场一般多用于双钩串车提升。
Lifting train with single hook and the hook. According to the different forms of parking and parking yard, rejection of peace. Single hook lifting train, can be used for multi level, generally use the swing yard. Yard is generally used for the double hook lifting train.

井口安全门有什么作用？
Safety gate what role?
为防止人员、矿车及其他物品坠落到井下，立井井口、井底和中间运输巷都必须设置安全门。井口安全门与提升信号联锁：安全门未关闭，发不出开车信号；发出开车信号后，安全门打不开；只有罐笼到位并发出停车信号后，安全门才能打开。
In order to prevent personnel, cars and other items fall to the bottom and the middle roadway underground, Takai Iguchi, must set the security door. Safety gate and hoist signal interlock safety door is not closed, no driving signal; a driving signal, the security door will not open; only the cage in place and a stop signal, the safety door can be opened.

什么叫防过卷装置？
What is the name of overwind device?
当提升机运行到正常卸载位置未停车并继续向上提升称为过卷。过卷造成的严重后果是损坏天轮、井架。拉断钢丝绳导致提升容器坠落，撞坏井筒设施，甚至造成人员伤亡。使用双滚筒提升机时，一钩发生过卷时，另一钩则过放，放过则造成蹲罐事故。因此，提升机必须装有防止过卷装置。当提升容器超过正常终端停止位置（或出车平台）0。5米时，必须能自动断电，并能使保险闸（即安全闸）发生制动作用。
When the elevator to the normal unloading position did not stop and continue to promote called overwind. Is damaged, the derrick sheave volume caused by the serious consequences. Broken wire rope leads the hoisting container fall, damaged wellbore facilities, even casualties. The use of double drum hoist, a hook had a roll, another hook off, let is caused by shock tank accident. Therefore, the hoist must be installed to prevent overwind device. When the hoisting vessel exceeds the normal terminal stop position (or car platform) 0. 5 meters, can be automatically cut off, and can make the safety brake (i.e. safety brake) brake function.

防坠器的作用是什么？
What is the role of anti dropping device?
防坠器又称断绳保护器，按规定立井罐笼和斜井人车系统都必须装设。当提升钢丝绳呀连接装置断裂时，罐笼断绳保险器能迅速、自动、准确地使立井罐笼平稳地支撑在罐道（或制动绳）上；斜井人车断绳保险器能迅速使斜井人车制动，防止其继续下滑。
Anti dropping device and rope breaking protector, shaft cage and in accordance with the provisions of slopecar system must be installed. When the lifting rope, connecting device is broken, the cage parachute can quickly and automatically and accurately make the shaft cage smoothly supported in the tank (or brake rope); slopecar parachute can quickly make man car brake, to prevent the continued decline.
