Coordinated hoisting control system of foldable type drilling machine base

Abstract

The invention relates to a coordinated hoisting control system of a foldable type drilling machine base, comprising a lower part truss and an upper part truss, wherein the lower part truss and the upper part truss are connected through a supporting rod system and a plurality of foldable supporting leg assemblies; a hinged node is arranged at the middle part of each foldable supporting leg assembly; the nodes of a plurality of the foldable supporting leg assemblies are connected together through a stable hoisting structure; the stable hoisting structure is connected with a hoisting power system; the upper part truss is connected with a hoisting restriction system for restricting the upper part truss to move upward in a vertical direction; a rotary chassis is arranged at the upper end of the upper part truss; and the rotary chassis is provided with a positioning indicator and a rotary guide rail for mounting a drilling machine. According to the coordinated hoisting control system, a reinforced concrete or rubble foundation does not need to be built and the flexibility is strong; the height of a base main body part is flexile and adjustable so as to meet the requirements of different drilling positions; the drilling machine can realize 360-degree free azimuth angle adjustment on the base; the base can keep a horizontal and stable state; and the drilling machine can be inclined in a small angle so as to meet the requirements of drilling and sweeping holes.

Description

Technical field [0001] The invention relates to a coordinated lifting control system for a folding rig base, in particular to a novel rig base that realizes unfounded, vertical and other ladder lifting, free adjustment of the rig's position, and non-coordinated adjustment to adapt to site conditions. Background technique [0002] The bottom of the traditional mechanical geological tunnel drilling rig is not convenient to be directly placed on the ground for construction. Generally, the construction foundation must be used as the rig base to increase the stability of the rig and meet the requirements of the height of the rig's working platform. The foundations of basic drilling rigs currently in use are mostly reinforced concrete prefabricated foundations and rubble pouring foundations. The two foundations are characterized by strong firmness. According to the drilling rig operating position and platform size (height, area), prefabricated reinforced concrete foundations or on-site ...

AI Technical Summary

Problems solved by technology

However, these two foundations have the following disadvantages: (1) The transportation volume of materials such as earthwork and steel bars is large, and the construction is cumbersome, especially the construction of deep wells is not conducive to transportation; (2) The foundation is fixed in place after construction, and its position cannot be adjusted flexibly. The foundation needs to be rebuilt according to the designed drilling position; (3) The height of the base is fixed after construction, which is difficult to meet the requirements of a higher construction platform. If necessary, the drilling rig can only be moved down to increase the foundation, which is time-consuming and laborious; (4) Poor adaptability to soft ground , uneven settlement often occurs and the platform tilts, causing the drilling rig to fail to complete normal drilling

In addition, during the grouting process, under the action of the grouting pressure, the bottom plate of the soft rock stratum may experience phenomena such as floor heaving and uneven lifting, which will reduce the integrity and stability of the base of the basic drilling rig, and in serious cases will cause safety accidents
