Rotary drilling rig carrying dual-system power station

Abstract

A rotary drilling rig carrying double-system power stations comprises the power stations symmetrically arranged on the two sides of the rotary drilling rig, each power station comprises a power station box body assembly and an internal power system, and each power station box body assembly comprises a box body frame, a mounting support, a flitch, a mounting plate, a machine shed covering part, a side door and an escalator; the internal power system comprises an engine assembly, a pump assembly, a fuel tank, a hydraulic oil tank and a radiator, and the internal power system is connected with a hydraulic pipeline of a main machine platform of the rotary drilling rig through a quick change device. According to the rotary drilling rig carrying the double-system power station, the power requirement of a super-tonnage rotary drilling rig can be met, the overall manufacturing cost is reduced, the double-system power station can be rapidly disassembled when the rotary drilling rig is transferred and transported, the transportation size and weight requirements are met, and after the rotary drilling rig reaches a construction site, the double-system power station is connected through a pin shaft and a quick-change connector; the device can be quickly mounted on a dual-system power station, is quick to disassemble and assemble, and is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a rotary drilling rig equipped with a dual-system power station. Background technique [0002] With the increasingly high requirements for pile foundation construction, super-large, super-wide and super-heavy rotary drilling rigs appear. The power demand of super tonnage rotary drilling rigs is getting higher and higher, and it is not easy for a single engine to meet the power output requirements. If unconventional high-power engines are used, the cost of construction and maintenance will be higher, and the application limitations will be larger; The excavation rig is too wide and heavy, and it is difficult to meet the size and weight requirements when it is transported. In view of the above problems, a dual-system power station is required, which can be mounted on both sides of the large vertical plate of the rotary drilling rig turntable. When the rotary drilli...
