Abstract

The invention discloses a pinion and rack drilling rig derrick structure and an installation method thereof. A bottom section derrick is installed at the tops of two bottom support frames, the top ofthe bottom section derrick is provided with a plurality of sections of middle section derricks in a supported mode, and the top of the topmost middle section derrick is fixedly provided with a top section derrick; and the inner wall of the bottom section derrick is fixedly provided with a bottom section rack assembly, the inner wall of each middle section derrick is fixedly provided with a middlesection rack assembly, and the inner wall of the top section derrick is fixedly provided with a top section rack assembly. The derrick structure adopting the stricture can be used for supporting and installing of a pinion and rack drilling rig, the rack assemblies are symmetrically installed inside the derricks, the rack assemblies adopt symmetrical structures, thus it is ensured that a drilling rig trolley can be engaged with the rack assemblies for transmission, and then stability of transmission of the drilling rig trolley is ensured, so that generated unbalanced force of the drilling rig trolley in the climbing process is effectively prevented.

Description

technical field [0001] The invention relates to a rack and pinion drilling rig derrick structure and an installation method, belonging to the field of drilling rig frame devices. Background technique [0002] The rack on the derrick of the existing rack and pinion drilling rig is installed on the inner wall of the derrick. For example, CN 103397849 A discloses a rack and pinion derrick for inclined straight wells. The rack of this derrick structure is fixed and installed on the side wall. . The above-mentioned installation method will cause an unbalanced force during the meshing process of the rack and pinion, which is prone to jamming, and affects the drilling force of the drilling rig, thereby affecting the drilling efficiency. Contents of the invention [0003] The main purpose of the present invention is to provide a rack and pinion drilling rig derrick structure and its installation method. The racks of the rack and pinion drilling rig derrick structure adopt a symme...
