A double drill rod linkage lifting device

Abstract

The invention provides a dual-drill rod linkage lifting device comprising a work platform, a telescopic rod, a connecting rod, a column I, and a column II; the columns I and II are respectively arranged on two sides of the work platform; one end of the telescopic rod is movably hinged to the work platform, and the other end is movably hinged to the middle of the column I; one end of the connecting rod is movably hinged to the upper portion of the column I, and the other end is movably hinged to the middle portion of the column II; the telescopic rod is a hydraulic rod; a hydraulic rod cylinder body is movably hinged to the work platform; the piston rod of the hydraulic rod is movably hinged to the middle of the column I; the bottom of the column I is movably hinged to the work platform; the column I is drawn by the telescopic rod so as to topple towards the inner side of the work platform, thus contracting or lowering the column I. The dual-drill rod linkage lifting device is reasonable in structure design, good in effect, and the column can be conveniently contracted and lowering.

Description

technical field [0001] The invention relates to a piling machine, in particular to a double drilling rod linkage lifting device. Background technique [0002] Modern construction projects of various types, such as housing, real estate foundation piles, road and bridge foundation piles, etc., must carry out foundation treatment piling or bored piles, etc. Rotary drilling rigs are preferred in the current market due to their fast construction speed and low engineering costs. However, the special rotary excavation equipment is relatively heavy, and the mechanical volume is too large. In the application of small projects, the project cost is often high due to excessive investment, and the small rotary excavators used are often due to insufficient power or insufficient drill pipes. The stability leads to poor drilling quality, which affects the quality of the project and easily affects the progress of the project. The existing double-column multi-functional rotary excavator can ...

[0002] Modern construction projects of various types, such as housing, real estate foundation piles, road and bridge foundation piles, etc., must carry out foundation treatment piling or bored piles, etc. Rotary drilling rigs are preferred in the current market due to their fast construction speed and low engineering cost. However, the special rotary excavation equipment is relatively heavy, and the mechanical volume is too large. In the application of small projects, the project cost is often high due to excessive investment, and the small rotary excavators used are often due to insufficient power or insufficient drill pipes. The stability leads to poor drilling quality, which affects the quality of the project and easily affects the progress of the project

The existing double-column multi-functional rotary excavator can better solve the above problems in engineering applications. However, the height of the double-column is often high, and it is easy to cause safety hazards in the non-working state, and it is not convenient for transportation and replacement. drill bits or hammers, etc.
