Integrated casing pipe drilling machine

Abstract

The invention discloses an integrated casing pipe drilling machine and belongs to the technical field of cast-in-place pile construction. The integrated casing pipe drilling machine is designed in order to solve the problem that the number of equipment needed currently is large. The integrated casing pipe drilling machine comprises a walking device. A dematron working device and a rotary platform are arranged on the walking device. An arm rest and a winding system are arranged on the rotary platform, a winding rope of the winding system strides the end of the arm rest, and the free end of the winding rope is connected to a percussion clamshell. The rotary platform can drive the percussion clamshell to rotate in the plane through the arm rest to convey materials grasped in the percussion clamshell to a designated position. According to the integrated casing pipe drilling machine, through the reasonable layout and the cross use of similar parts, the input of the equipment is reduced; a power system of multiple devices can be shared, the utilization rate of the power system is increased, all parts of the whole machine are tightly matched and are good in coordination and high in automation degree, no additional balance weight needs to be added to the dematron working device, use is convenient, the use cost is low, and the number of needed operators is small.

Description

technical field [0001] The invention relates to the technical field of cast-in-situ pile construction, in particular to an integrated casing drilling rig. Background technique [0002] Cast-in-situ pile method is widely used in the field of piling construction. The so-called cast-in-place pile is to take soil at the set position to form a hole, and then pour concrete into the hole to form a pile. Usually, the Benoit method is used to complete the above work. The core idea of ​​the Benoit method is to follow up the casing wall while punching and grabbing the drilling. [0003] The implementation of Benoy's method requires the use of various devices, mainly including a crane, a full-rotation full casing drilling machine (or pipe rubbing machine), and a punching grab. During operation, the casing is driven to rotate by the full-rotation casing drilling machine, and the cutting teeth installed at the boot at the bottom of the casing cut the soil layer or rock layer under the ac...

AI Technical Summary

Problems solved by technology

[0004] The defects of the prior art are: 1. There are too many devices involved, and it is difficult to cooperate with each other. It takes a long time to adjust a certain device to a station, the work efficiency is low, and the degree of automation is low; 2. The full-rotation full casing Drilling machine or pipe rubbing machine itself lacks a moving structure. It needs to be dragged by other equipment when transitioning. The maneuverability is poor, and a lot of time is wasted on loading or unloading between the drilling machine or pipe rubbing machine and the dragging device. , the work efficiency is low; 3. The full-rotation full casing drilling machine or pipe twisting machine needs to add additional counterweight when using it to overcome the support reaction force of the casing to the equipment when the casing is pressurized, which is inconvenient to use
