Below drilling platforms deck plane.
Preferably, head rig side unit is closed at the top of the derrick main body, is respectively equipped with one at auxiliary drilling machine side unit
Overhead traveling crane is equipped with two sets of top drive guide rails on the side wall of derrick main body.
Preferably, on the pedestal close to driller at side unit be equipped with drilling tool movement mechanical arm.
Beneficial effects of the present invention are：
（1）Derrick of the present invention is four supporting leg open front structures, driller's side unit leading flank opening, convenient for drilling tool
Movement；Quadruple board platform and tube drawbench are located at the outside of derrick main body so that the capacity of quadruple board platform is not by derrick independently with derrick main body
The influence of main body, increases the storing capacity of drilling tool, while having saved the inner space of derrick main body, derrick main body section size
Become smaller, reduce the volume of derrick main body, reduces the weight of derrick main body；
（2）Derrick main body of the present invention is located at main shaft mouth, among service shaft mouth, and derrick body top is equipped with two days
It is equipped with two sets of top drive guide rails in vehicle, derrick main body, convenient for head rig, auxiliary drilling machine coordinative operation, improves work efficiency；
（3）Quadruple board platform is located at the outside of derrick main body, the length of thribble half be located at drilling platforms main deck surface with
Under, the height of quadruple board platform is effectively reduced, born wind load is reduced.
