Piling Machinery XR150D CAF LONG AUGER DRILLING RIG
The long auger drilling machine is composed of motor, reducer, drill pipe and drill bit, etc., the whole set of drilling machine is suspended on the pile frame through the trolley group, and the lifting frame and position of the drilling machine are controlled by the pile frame. The motor on the drilling tool is suitable for operation under full load and has a good overload protection device. Most of the reducers adopt vertical planetary reducers. In order to ensure the stability of the drill pipe drilling and the accuracy during initial drilling, an intermediate rod stabilizer is installed at 1/2 of the length of the drill pipe, which is suspended from the power head of the drill with a wire rope, and moves up and down along the pile frame column with the power head. The lower part of the drill pipe is equipped with a guide ring, the guide ring is fixed on the pile frame column, the drill pipe is a steel pipe welded with spiral blades, and the drill pipe with long screw is made in multiple sections; Commonly used hollow drill pipe, there are vertical holes through up and down in the drilling machine, concrete can be poured directly from the hole after the completion of drilling L, and the drill pipe is slowly lifted while pouring, which is conducive to the stability of the hole wall, reduce the collapse of the hole, and improve the quality of the pile. When drilling, the soil sheet at the bottom of the hole rises along the spiral blades of the drill pipe to unload the soil around the drill pipe or transport it by unloading it in a transport such as a dumper through a discharge hopper. The hole diameter of the long auger drilling machine is not more than 1m, and in order to meet the drilling needs of different formations, it is equipped with a variety of different drill bits, which is suitable for the construction of clay and sand layers with low groundwater table. The long auger drilling machine is mostly driven by hydraulic motor, its own weight is light, the speed regulation is convenient, and the hydraulic power is provided by the crawler pile frame.
