Rotary drilling rig

Abstract

The invention discloses a rotary drilling rig. The rotary drilling rig comprises a drill rod and masts, the drill rod is arranged on the mast, two connecting parts of two ends of the drill rod and themasts are separately close to the first ends and the second ends of the masts; the masts comprises the first mast and the second mast, the end of the first mast and the end of the second mast are rotatably connected, the first mast and the second mast rotate relatively to enable the first mast to be in straight line butt-joint with the second mast, and the height of the first ends and the secondends can be reduced to achieve the reduction of height of the drill rod. According to the rotary drilling rig, the drill rod is not required to be disassembled in the transition process, the workloadof the transition is reduced, the efficiency of the transition is improved, a plurality of transport vehicles are not required to transport the rotary drilling rig, and the transportation cost is reduced.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a rotary drilling rig. Background technique [0002] The transfer of rotary drilling rigs is an event with high frequency, so the quality of the rotary drilling rig transportation plan is directly related to the transfer cycle and transfer costs. Such as figure 1 As shown, the drill pipe 01 of the rotary drilling rig is set on the top of the mast 02, and its installation height is relatively large. Due to the large volume of the rotary drilling rig, the rotary drilling rig often fails to meet the road transportation requirements during the transition process. (For example, there is a height limit requirement in some road sections, and the height of the drill pipe 01 will be greater than the height limit height). Therefore, the current rotary drilling rig adopts the method of disassembling the drill pipe 01 to reduce the overall height of the rotary drilling rig whe...

Problems solved by technology

like figure 1 As shown, the drill pipe 01 of the rotary drilling rig is set on the top of the mast 02, and its installation height is relatively large. Due to the large volume of the rotary drilling rig, the rotary drilling rig often fails to meet the road transportation requirements during the transition process. (For example, there is a height limit requirement in some road sections, and the height of the drill pipe 01 will be greater than the height limit height). Therefore, the current rotary drilling rig adopts the method of disassembling the drill pipe 01 to reduce the overall height of the rotary drilling rig when it is transferred. This kind of transportation method for disassembling the drill pipe 01 requires a lot of work and time-consuming when disassembling the drill pipe 01, and requires multiple transport vehicles to transport multiple parts after disassembly, resulting in high transportation costs
