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, the ground conditions are various. When the rotary drilling pile drilling machine is drilling, if there is a soft soil layer, loose soil layer or watery sandstone layer in the pile hole geology, it is very easy to collapse, resulting in the rotary drilling tool being stuck in the pile hole. It is buried by soil; if there is a rock layer in the pile hole geology, the drilling tools of the rotary excavator will wear a lot, and the fuel consumption will be large, the project cost will be high, and the project continuity will be poor, which will easily affect the project. schedule

Embodiment 1

[0050] Example 1: as figure 1 As shown in the figure, when the soft soil layer geology causes the pile hole to collapse during the rotary excavation process, the three-compound soil mixed with sand, stone and soil can be added to the pile hole, and the three-composite soil can be rotated by the hammer installed on the column II4. After the dynamic compaction process becomes a solid layer, the rotary drilling tool is used to drill holes; when encountering rock layer geology, a punching hammer can be installed at the installation end 42, and the free-fall hammer hoist 29 can be started to drive the punching hammer along the After the column II4 rises vertically for a certain distance, the clutch release gear is activated, and the punching hammer falls freely under its own weight to impact the pile hole, perform repeated dynamic ramming, and rush into the rock.

Embodiment 2

[0051] Example 2: as figure 2 As shown, when the vibrating sinking operation needs to be performed after the pile hole is poured, the vibrating sinking pile is replaced and installed at the installation end 42, and the vibrating sinking pile enters the pile hole vertically downward along the column II4 to perform the vibrating sinking operation of the pile hole.

Embodiment 3

[0052] Example 3: as image 3 , 4 As shown, when a rotary excavation operation is required, a movable assembly table 45 is installed on the sliding guide rail 46, a motor is installed on the upper end of the movable assembly table 45, and the mounting end 42 is also connected to the movable assembly table 45, and the movable assembly table 45 can be installed in the Under the traction of the wire rope, the lifting motion is performed along the sliding guide rail 46; the lower part of the movable assembly table 45 is installed with a long auger pile, and the free-fall hammer hoist 29 and the motor on the movable assembly table 45 are activated, and the long auger pile is vertically along the column II4. Do the rotary drilling operation.

Abstract

The invention provides a multifunctional rotary drilling machine comprising a machine frame, a work platform, a column I, a column II, a drilling rod assembly, a movable assemble mechanism, and a drive unit; the work platform is arranged on the machine frame through a rotary plate; the columns I and II are respectively vertically arranged on two sides of the work platform; the columns I and II can be switched in usage by the rotary plate at any time in a working process; the drilling rod assembly is arranged on the column I; the movable assemble mechanism is arranged on the column II; corresponding drilling tools or hammerheads can be assembled according to different geological conditions; the drive unit is arranged on the work platform, and used for respectively driving the drilling rod assembly to vertically move on the column I and driving the movable assemble mechanism to vertical move on the column II. The multifunctional rotary drilling machine is reasonable in structure design, low in cost, and good in effect.

Description

technical field [0001] The invention relates to a pile construction machine, in particular to a multifunctional rotary excavator. Background technique [0002] Modern construction projects, such as houses, real estate foundation piles, road and bridge foundation piles, etc., must be treated with foundation treatment, piling or drilled piles, etc. Rotary drilling rigs are preferred in the current market due to their fast construction speed and low engineering costs. However, the foundation conditions are various. When the rotary drilling machine is drilling, if it encounters a soft soil layer, a loose soil layer or a water sandstone layer in the pile hole geology, it is easy to collapse, resulting in the rotary drilling tool in the pile hole. It is buried by Ni soil; if there is a rock layer in the pile hole geology, the drilling tools of the rotary excavator to dig the rock are greatly worn, and the fuel consumption is also large, the project cost is high, and the project co...
