The utility model discloses a self -elevating drilling unit immersible pump hoist and mount system, it includes each section leading water pipe and immersible pump, the leading water pipe passes through flange joint with the immersible pump of below, install the lug on every section leading water pipe, it passes through the lug and connects a wire rope to be located the leading water pipe lower extreme of below, terminal and the lug structrual joint of this wire rope, it installs the blind plate on the flange of the leading water pipe bottom of below to be located, blind plate under the installation on the flange of dive pump top portion, upward all install rings on blind plate and the lower blind plate, lower blind plate passes through rings and is connected with a main hook, the main hook is connected with main wire rope, near immersible pump sets up and is used for the setting hook, tear the multilayer platform of hook open. With immersible pump and leading water pipe separation, during hoist and mount, the supplementary design of cooperation remains the leading water pipe on the spud leg, only hoists the immersible pump, and the time that the immersible pump was changed in the maintenance shortens greatly, has saved a large amount of manpowers, has avoided the too much damage of cable.
