Abstract

The invention discloses a surface hole drilling device for non-excavation construction pipelines. The device comprises a base board, a bottom board, a first hole drilling machine, a second hole drilling machine and pipeline rotary mechanisms; the bottom board is located below the base board; the base board is fixedly connected with the bottom board through a supporting rod; two guide grooves are formed in the top face of the base board in parallel; the first hole drilling mechanism and the second hole drilling mechanism are movably connected to the guide groove; a drive mechanism is arranged between the base board and the bottom board and is connected with the first hole drilling mechanism and the second hole drilling mechanism; pipeline supporting mechanisms are arranged on the center straight line of the top face of the base board at equal intervals; and the two pipeline rotary mechanisms are symmetrically arranged on two sides of the base board. The surface hole drilling device fornon-excavation construction pipelines is simple in structure and high in practicability, not only can achieve single-hole or dual-hole machining for construction pipelines and improve the hole drilling efficiency, but also can clamp and position construction pipelines, rotates construction pipelines at the constant speed according to hole drilling needs at the same time, and greatly improves the hole drilling precision and quality.

Description

technical field [0001] The invention relates to a surface drilling device for non-excavating construction pipelines. Background technique [0002] Pipeline engineering is generally used to transport oil, natural gas and solid slurry, including pipeline line engineering, station warehouse engineering and pipeline ancillary engineering. During pipeline construction, it is generally necessary to process the pipeline to meet the needs of actual installation. When the surface of the pipeline is drilled, it is a processing method for the pipeline. The precision of the drilling directly affects the installation precision and quality of the pipeline. [0003] Existing surface drilling of pipelines generally adopts manual drilling, or drilling processing is carried out by drilling equipment before the pipeline leaves the factory. However, the drilling accuracy on the surface of the construction pipeline is low, and the efficiency is not high, and automatic continuous production can...
