Rotary drilling rig capable of being fully transported with drill pipe

Abstract

The invention discloses a rotary drilling rig capable of being fully transported with a drill pipe. The rotary drilling rig comprises a revolving platform (2), a weight (4), a jib luffing mechanism (6), a vertical mast cylinder (7), a mast (8), a follow frame (10), the drill pipe (11), a power head (12) and a lower mast (14); the follow frame (10) is fixedly connected with the mast (8) in transportation, and the drill pipe (11) is fixedly connected with the follow frame (10) and the power head (12) with no need of disassembling. By the arrangement, the drill pipe does not need to be disassembled when the rotary drilling rig is to be transported to other site, the masts can be directly erected for construction when the rotary drilling rig is transported to the construction site, hoisting equipment is not needed for assistance during the whole process, manpower is reduced, time is saved, construction efficiency is greatly improved, and construction cost is lowered.

Description

technical field [0001] The invention relates to a rotary drilling rig, in particular to a transport rotary drilling rig with rods. Background technique [0002] The application of rotary drilling rigs in civil construction projects is becoming more and more mature, and it is used more and more in the construction of villages and towns. In the case of narrow roads and many structures, the rotary drilling machine used to transport the drill pipe It is disassembled from the main engine for transportation, and the drill pipe is installed on the main engine after the equipment enters the construction site, so it takes a lot of time and labor, including renting other lifting equipment. [0003] Secondly, some construction sites have limited space and cannot accommodate rotary drilling rigs and lifting equipment at the same time; in addition, many construction sites have a small number of pile holes, short construction periods, and frequent transitions; in these cases, the installa...

Problems solved by technology

[0002] The application of rotary drilling rigs in civil construction projects is becoming more and more mature, and it is used more and more in the construction of villages and towns. In the case of narrow roads and many structures, the rotary drilling machine used to transport the drill pipe It is disassembled from the main engine for transportation, and the drill pipe is installed on the main engine after the equipment enters the construction site, so it takes a lot of time and labor, including renting other lifting equipment

[0003] Secondly, some construction sites have limited space and cannot accommodate rotary drilling rigs and lifting equipment at the same time; in addition, many construction sites have a small number of pile holes, short construction periods, and frequent transitions; in these cases, the installation time of rotary drilling rigs occupies most of the construction time

[0004] In short, the above-mentioned rotary drilling rigs have low efficiency and high construction costs under similar conditions, and cannot meet the needs of high efficiency and low cost
