Problems solved by technology

This scheme uses hollow drill pipes for slurry transportation. When the hollow drill pipes have multiple sections, the drill pipes need to be connected. However, the length of the telescopic drill pipe is limited after all, and its principle is obviously different from that of the pressure-holding drill pipe.
[0005] To sum up, it can be seen that when the drill pipe needs to be driven below the ground at a certain depth, the shortcoming of intermittent operation will occur when the pressure is used to work, and the continuity of the drilling work will be affected. In addition, the verticality of the drill pipe There is no guarantee, which will affect the quality of the project

Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] Such as figure 1 and Figure 6 As shown, a drill pipe double-hugging pressure system for a pile driver includes a pressure-hugging platform 1. The pressure-hugging platform 1 is provided with a tool for holding the drill pipe 100 and can drive the drill pipe in the vertical direction. The primary holding pressure mechanism 2 of the movement, the holding pressure table 1 is also provided with a secondary holding pressure mechanism 3 that can hold the drill pipe 100 tightly and drive the drill pipe to move in the vertical direction, and when the above described When the secondary holding pressure mechanism 3 tightly hugs the drill pipe, the axis line of the secondary holding pressure mechanism 3 coincides with the axis line of the primary holding pressure mechanism 2 .

[0029] Those skilled in the art should understand that th...

Abstract

The invention belongs to the technical field of buildings and relates to a drill pipe double-clamping system for a pile driver. The system comprises a clamping table, wherein a primary clamping mechanism which is used for clamping a drill pipe and can drive the drill pipe to move vertically is arranged on the clamping table, a secondary clamping mechanism which can hold the drill pipe and can drive the drill pipe to move vertically is arranged on the clamping table, and when the secondary clamping mechanism holds the drill pipe, the axis of the second clamping mechanism coincides with that of the primary clamping mechanism. The system adopts two clamping mechanisms and can realize continuous drilling operation, the operation efficiency is improved, the axes of the two clamping mechanisms coincide during working, the drill pipe is always supported by force during drilling, so that the perpendicularity of the drill pipe is guaranteed, and the engineering quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of construction, and relates to a drill pipe, in particular to a drill pipe double-hugging pressure system for a pile driver. 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 pipe...
