Problems solved by technology

[0002]In the construction of mixing piles in railway, highway, construction, municipal, water conservancy, and port projects, the pile driver usually uses the drill bit to rotate in one direction to drill and mix. Pile, there is a slurry phenomenon, the efficiency is low, and the quality is not easy to guarantee
Recent literature shows that the use of double motors and double drill rods for bidirectional drilling and mixing improves the drilling efficiency and pile quality, but the pile machine needs to be modified or remanufactured,

Embodiment Construction

[0020] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0021] As shown in Figures 1, 2, and 3, taking a group of 4-layer forward and reverse mixing pile machines as an example, the single-power, two-way drilling mixing pile machine of the present invention includes a forward-rotating drill rod 17 and a reverse-rotating drill rod 16. , motor 18, frame 25, mixing tank and mud pump 27, drill bit blades 23, 24 and the epicyclic gear train mechanism 40 that changes the direction of rotation of the forward drill rod 17 and the reverse drill rod 16, and the epicyclic gear train mechanism 40 is positioned at the drill rod The top, makes the epicyclic gear train become the fixed plate 19 of the fixed axle gear train and is fixed on the motor 18 seat of the stirring pile driver top that does not rotate with motor 18.

[0022] The fixed plate 19 can also be fixed on the frame 25 and the water joint 26 that do ...

Abstract

The invention discloses a mono-dynamics bidirectional drilling mixing pile machine, comprising a forward rotating drilling rod, a reverse rotating drilling rod, an electric motor, a framework, a mixing can, a slush pump, bit blades, and a cyclic gear train mechanism for changing directions of the forward rotating drilling rod and the reverse rotating drilling rod. The cyclic gear train is disposed on the upper portion of the drilling rod. A fixation plate for changing the cyclic gear train to an ordinary gear train is fixed on the upper portion of the mixing pile machine which does not rotating with the electric motor. The invented method implements forward and reverse bidirectional drilling and mixing of the pile machine without changing structure and operation method of the traditional mixing pile machine; and the piling speed and piling quality are enhanced.

Description

technical field [0001] The invention relates to a stirring pile driver, in particular to a single-power, two-way drilling stirring pile driver. Background technique [0002] In the construction of mixing piles in railway, highway, construction, municipal, water conservancy, and port projects, the pile driver usually uses the drill bit to rotate in one direction to drill, stir, and form piles. Slurry phenomenon occurs, the efficiency is low, and the quality is not easy to guarantee. Recent literature has shown that the use of double motors and double drill rods for bidirectional drilling and mixing has improved drilling efficiency and pile quality, but the pile machine needs to be rebuilt or remanufactured, which is costly. [0003] The Chinese patent 200720097836.3 applied by the applicant achieves single-power two-way multi-layer mixing through the epicyclic gear train mechanism, but since the epicyclic gear train mechanism is installed on the drill bit, during the pile for...
