Novel super level directed drilling machine

Abstract

The invention provides a novel super level directed drilling machine comprising a crossbeam. A chassis is mounted on the lower part of the crossbeam. A crossbeam adjustment oil cylinder and a crossbeam elevation angle oil cylinder are correspondingly fixed at both ends of the chassis. Multiple supporting seats are mounted at the bottom portion of the crossbeam through a crossbeam sliding plate. The supporting seats are connected with the crossbeam adjustment oil cylinder and the crossbeam elevation angle oil cylinder through fasteners. A crossbeam sliding oil cylinder and supporting legs are further mounted at the bottom portion of the crossbeam. A workbench is arranged at one end of the upper portion of the crossbeam. A static vice, a front dynamic vice and aback dynamic vice are installed correspondingly on the workbench. A double-drill -pipe structure penetrates through a vice. Double drill pipes comprise the inner drill pipe and the outer drill pipe. The inner drill pipe penetratesthrough the inside of the outer drill pipe. A walking trolley is installed at the other end of the upper portion of the crossbeam. A front power head is installed on the walking trolley. The front power head is connected with the outer drilling pipe by a front power head short joint. A back power head is arranged on the crossbeam and the back power head is connected with the inner drilling pipe by a back power head short joint. A push and pull oil cylinder is installed on the walking trolley. The output end of the push and pull oil cylinder is connected with the back power head. The novel super level directed drilling machine is reliable in operation.

Description

technical field [0001] The invention relates to the technical field of pipeline engineering construction, in particular to a novel super horizontal directional drilling machine. Background technique [0002] In the prior art, all horizontal directional drilling rigs adopt a single power head and single gripper structure, and a single drill pipe is used for feeding and pulling back during the construction process. Due to objective reasons such as the size of the drill pipe and the pullback force of the drilling rig, the long-distance guidance adopts the cross-penetration process. A large-tonnage drilling rig is installed at the entry point and the exit point of the pipeline, and the holes are drilled at the same time. The underground docking is quite difficult. Large, and the construction process is quite complicated, and the construction cost is quite expensive; in addition, in the past, horizontal directional drilling rig rock engineering reaming used the step-by-step recip...

Problems solved by technology

[0002] In the prior art, all horizontal directional drilling rigs use a single power head and a single gripper structure, and a single drill pipe is used for feeding and pulling back during the construction process.

Due to objective reasons such as the size of the drill pipe and the pullback force of the drilling rig, the long-distance guidance adopts the cross-penetration process. A large-tonnage drilling rig is installed at the entry point and the exit point of the pipeline, and the holes are drilled at the same time. The underground docking is quite difficult. Large, and the construction process is quite complicated, and the construction cost is quite expensive; in addition, in the past, horizontal directional drilling rig rock engineering reaming used the step-by-step reciprocating reaming process, the construction period was long and the construction cost was high; the previous horizontal directional drilling rig could not realize sewage pipe engineering below 800mm After the guide is completed, one-time full-end reaming and synchronous pull-back of the main tube

Both adopt mud-water balance pipe jacking method and directional drilling graded reaming and pulling back main pipe method. This kind of construction technology has a long construction period and high construction cost.
