ZJ32-SL_I型钻机上台装置

Sloping drive unit on Model ZJ32-SL_I drilling rig

针对在用钻机上台装置移运性差、安装困难和密闭润滑难以保证的问题，设计制造了高钻台、低底座的ＺＪ３２－ＳＬＩ型钻机。这种钻机采用了一种新型上台装置，整体布置有所改变，即取消了正车箱和猫头轴，并采用万向轴加角传动箱的传动驱动转盘，取消了驱动转盘的链条。同时，也改善了移运性能，保证了密闭润滑条件，达到了上台链条和绞车的密闭润滑部位在钻机搬迁时不需拆装的目的。

In the op of the poor mobility and the troubles with installation and lubrication of the sloping driveund on the existin drlling rigs,the Model ZJ32-SLI drilling rig with high floor and low substructrure isdeveloped. The rig adopts a new sloping drive device, so its general arrangement is changed, i.e. the forward gear box and the cat shaft are eliminated,and the cardan shaft and angle drive case ase are used for the rorary table drive and the rotary table drive chain is eliminated, SO the mobility of the sloping drive unit is improved and the sealed lubrication for the unit is guaranteed.By using this sloping drive unit, it is nunecessary to mount and dismount the sloping chain and the sealed lubricated part of the drawworks in rig .removal.
