Embodiment 1

[0027] Such as figure 1 and figure 2 As shown, a kind of material conveying pipeline mechanism of the drill pipe under power includes a drill pipe 1 and a length adjustment rod 2, and a power mechanism 3 is arranged between the drill pipe 1 and the length adjustment rod 2, and the power mechanism 3 and the drill pipe 1 is connected by driving and can drive the drill pipe 1 to rotate in the circumferential direction. The inside of the drill pipe 1 is provided with a feeding channel 4, and the bottom of the drill pipe 1 is provided with a discharge hole 4a. The discharge hole 4a is connected to the feed passage 4. The length adjustment rod 2 is provided with a slurry delivery pipe 5 and the slurry delivery tube 5 extends into the power mechanism 3, and a slurry delivery connection pipe 6 is arranged on the outer wall of the power mechanism 3, and one end of the slurry delivery connection pipe 6 is It is detachably connected with the slurry delivery pipe 5, and the other end is...

Embodiment 2

[0037] The structure and working principle of this embodiment are basically the same as that of Embodiment 1, the difference is that, as figure 1 As shown, the outer wall of the length adjustment rod 2 is provided with a wire groove 24 for embedding a hose, and the wire groove 24 is arranged along the axial direction of the length adjustment rod 2, as shown in Fig. 5 and Fig. The outer wall of the connection block 16 is provided with a wire insertion connection groove 25 matching with the wire insertion groove 24, and the second connection block 16 is provided with a pressing wheel (not shown in the figure).

[0038] In this embodiment, the slurry delivery pipe 5 and the gas delivery pipe 7 are arranged in the length adjustment rod 2, while the oil delivery pipe 9, electric wires and other flexible pipes are embedded in the embedded wire groove 24, and the butt connection is realized through the embedded wire connecting groove 25, so that the oil delivery pipe 9 , wires, etc. ...

Abstract

The invention belongs to the technical field of building, and relates to a material delivery pipe mechanism for a bottom-mounted power drill rod. The material delivery pipe mechanism comprises a drill rod and a length adjusting rod. A power mechanism is disposed between the drill rod and the length adjusting rod; the power mechanism is in driving connection with the drill rod, and is capable of driving the drill rod to rotate circumferentially. A delivery passage is formed within the drill rod, and a discharge hole is formed in the bottom of the drill rod and is communicated with the delivery passage. A slurry delivery pipe is disposed in the length adjusting rod, and extends into the power mechanism. A slurry delivery connecting pipe is disposed on the outer wall of the power mechanism, and one end of the slurry delivery connecting pipe is detachably connected to the slurry delivery pipe, while the other end of the slurry delivery connecting pipe is detachably connected to the delivery passage. The invention provides a delivery pipe mechanism capable of realizing bottom-mounted power of the drill rod, thereby guaranteeing that material can be delivered to the drill rod when power for the drill rod is mounted at bottom so as to obtain a high-strength cement soil mixing pile; no disturbance is produced for the power structure; and reliable and stable work is achieved.

Description

technical field [0001] The invention belongs to the technical field of construction and relates to a drill pipe, in particular to a material conveying pipeline mechanism for a power-down drill pipe. Background technique [0002] At present, there are two kinds of piling machines used on construction sites: one is the rotary piling machine. The structure of this piling machine is a drill pipe suspension frame pulled up by a hoist, and the drill pipe bit is driven by the power head to form a hole in the underground drilling machine. Pile driving equipment; the other is the impact hammer pile driver. The structure of this pile driver is to use the hoist to pull the impact hammer up and down repeatedly, and then lift it to realize pile driving. Among them, the rotary pile driver mainly realizes the purpose of drilling the drill pipe underground through the circumferential rotation of the drill pipe during piling. When the drill pipe is drilled, grouting is used to cool the drill...
