Construction requirements of various construction angles can be met, and design requirements of the whole machine can be met.

Description

technical field [0001] The invention relates to an angle adjustment mechanism, in particular to an angle adjustment mechanism of a multifunctional drilling rig. Background technique [0002] Multifunctional drilling rigs are rarely used at present, because the construction machinery used is different because of the different drilling angles. Most of the boreholes have the same diameter, and the included angle with the ground is different, so the construction technology of the hole is different. Because the construction angle is different, different machines must be used. Core drilling rigs are used for exploration, water well drilling rigs are used for hydrological and water well drilling, casing drilling rigs are used for pipe shed support, and bolt drilling rigs are used for slope anchoring, anchor cables, and expedition rescue. These drilling rigs have the same drilling diameter and depth but different angles. At the same time, they cannot replace each other. For example...

Problems solved by technology

Most of the boreholes have the same diameter, and the included angle with the ground is different, so the construction technology of the hole is different. Because the construction angle is different, different machines must be used. For example, horizontal directional drilling rigs are generally used when laying pipelines. Core drilling rigs are used for exploration, water well drilling rigs are used for hydrological and water well drilling, casing drilling rigs are used for pipe shed support, and bolt drilling rigs are used for slope anchoring, anchor cables, and expedition rescue. These drilling rigs have the same drilling diameter and depth but different angles. At the same time, they cannot replace each other. For example, a horizontal drilling rig is used for drilling horizontal holes, and a rotary drilling drill is used for drilling vertical holes. When drilling inclined holes, various construction machines must be used to assist multiple composite processes or even partial excavation. Many drilling reinforcement projects are located near existing buildings, road bridges, subway tunnels or civil air defense projects. The technical complexity is higher than that of the foundation structure, the construction technology is unreasonable, and the improper drilling angle not only endangers its own safety, but also brings disaster to the surrounding area. various facilities, causing serious damage

However, different types of drilling rigs are required for drilling holes with the same specifications and different angles, which leads to a great waste of resources.
