Problems solved by technology

[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, most of the currently used rotary excavators are single-column structures, and only have the single function of rotary excavation with many pile holes. When the foundation conditions are diverse, or when operations such as tamping holes are required on the construction site, the rotary drilling rig is very difficult. Incapable of doing what one wants, additional auxiliary equipment is required, the project cost is high, and the project progress is slow, which can easily affect the project progress

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] Such as figure 1 As shown, a double column structure of a rotary excavator includes a frame 1, a working platform 2, a column I3, a column II4, and a driving device; the working platform 2 is installed on the frame 1; the column I3 and The column II4 is installed vertically on both sides of the working platform 2 respectively; the rotary drilling drill is set on the column I3, and the free-fall hammer mechanism is set on the column II4.

[0022] The driving device is installed on the working platform 2, respectively drives the rotary drilling drill on the column I3 and drives the free-fall hammer mechanism to move vertically on the column II4.

[0023] The driving device includes a winch I28, a free-fall hammer hoist 29 and a rotary digging pressurized hydraulic cylinder 36. The winch I28 and the free-fall hammer hoist 29 are installed ...

Abstract

The invention provides a rotary drilling machine double-column structure comprising a frame, a work platform, a column I, a column II and a drive unit; the work platform is arranged on the frame; the columns I and II are respectively vertically arranged on two sides of the work platform; the column I is provided with a rotary drill; the column II is provided with a free falling hammer mechanism; the drive unit is arranged on the work platform, and used for respectively driving the rotary drill to vertically move on the column I and the free falling hammer mechanism to vertically move on the column II. The rotary drilling machine double-column structure is reasonable in structure design, low in cost, and good in effect.

Description

technical field [0001] The invention relates to a piling machine, in particular to a double column structure of a rotary excavator. 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, most of the currently used rotary excavators are single-column structures, and only have the single function of rotary excavation with many pile holes. When the foundation conditions are diverse, or when operations such as tamping holes are required on the construction site, the rotary drilling rig is very difficult. Insufficient, need additional auxiliary equipment, high project cost, slow project progress, very easy to affect the progress of the project. Contents of the invention [0003] ...
