Problems solved by technology

Unqualified quality of derrick installation and foundation bearing capacity will cause serious safety accidents
At the same time, during the installation of the derrick, the construction time of the wellhead foundation is occupied, which brings certain difficulties and challenges to some construction projects with tight schedules and high requirements.
During the drilling construction, it is necessary to install a gantry crane to transport the well wall, drilling tools, equipment, etc., which invisibly increases the construction cost of the project

Abstract

The invention discloses a walkable multipurpose large shaft headgear. The walkable multipurpose large shaft headgear comprises a movable door type headgear, wherein the two sides of the movable door type headgear are connected with supporting winch sets through load supporting arms, headgear walking mechanisms are installed at the bottoms of the two sides of the movable door type headgear, a linear bearing beam is connected to the lower ends of the supporting winch sets through noose devices, a lifting device is connected to the lower end of the linear bearing beam, a water faucet and a driving drill rod are sequentially connected below the lifting device, a loading disc is connected below the driving drill rod, and the loading disc is installed on a sealing beam; and a slurry outlet pipeis connected to the water faucet. The lower portions of the winch sets are supported and walk through sealing vehicle walking mechanisms, the sealing vehicle walking mechanisms are matched with sealing vehicle tracks to walk, the bearing pressure of the headgear walking mechanisms of the movable door type headgear is relieved, and therefore the supporting performance of the walkable multipurpose large shaft headgear is improved.

Description

technical field [0001] The invention relates to the technical field of well-sinking construction by drilling method, in particular to a walkable multi-purpose large shaft derrick. Background technique [0002] The derrick is an important part of the well-sinking construction of the drilling method. It is mainly used to place the crown block, hang the traveling block, hook, lifting ring, elevator, and lift and store drill pipes and other equipment. The installation requirements of the derrick are strict, and it should have sufficient strength, rigidity and overall stability, and the bearing capacity of the foundation should also meet the construction requirements. The unqualified quality of derrick installation and foundation bearing capacity will cause serious safety accidents. At the same time, during the derrick installation process, the construction time of the wellhead foundation is occupied, which brings certain difficulties and challenges to some construction projects...
