It is preferred that, the apical side height of the quadruple board platform is located at 1/2nd of thribble on the bottom of derrick main body, quadruple board platform
Below drilling platforms deck plane.
It is preferred that, head rig side unit is closed at the top of the derrick main body, one is respectively equipped with auxiliary rig side unit
Two sets of top drive guide rails are installed on overhead traveling crane, the side wall of derrick main body.
It is preferred that, close to driller to being provided with drilling tool movement mechanical arm at side unit on the base.
The beneficial effects of the utility model are：
（1）Derrick described in the utility model is four supporting leg open front structures, and driller's side unit leading flank opening is easy to bore
The movement of tool；Quadruple board platform and tube drawbench are independent with derrick main body, positioned at the outside of derrick main body so that the capacity of quadruple board platform not by
The influence of derrick main body, adds the storing capacity of drilling tool, while the inner space of derrick main body has been saved, derrick main body section
Size diminishes, and reduces the volume of derrick main body, reduces the weight of derrick main body；
（2）Derrick main body described in the utility model is in the middle of main shaft mouthful, service shaft mouthful, and derrick body top is provided with two
Provided with two sets of top drive guide rails in overhead traveling crane, derrick main body, it is easy to head rig, auxiliary rig coordinative operation, improves operating efficiency；
（3）Quadruple board platform is located at the outside of derrick main body, the length of thribble 1/2nd be located at drilling platforms main deck surface with
Under, the height of quadruple board platform is effectively reduced, born wind load is reduced.
