Walking type omnibearing rotary hydraulic pile foundation drilling machine
Technical Field
The invention relates to a pile foundation drilling machine suitable for a narrow space region, in particular to a hydraulic pile foundation drilling machine capable of rotating in all directions, and belongs to the field of road and bridge engineering.
Background
In the road and bridge building construction, the foundation treatment is a very important link, the pile foundation treatment is a common foundation treatment mode, namely, after the pile foundation is drilled into a hole, the drilled hole is filled or backfilled and tamped, so that the bearing capacity of the foundation is improved, the requirements of the design on the bearing capacity and the stability of the foundation are met, the anti-seismic performance of the foundation is improved, the deformation property of the foundation is improved, the applicability, the safety, the durability and other use functions of road and bridge engineering are met, and the pile foundation treatment is to be completed firstly by drilling the pile foundation.
In pile foundation drilling construction, currently, drilling equipment commonly used includes a rotary drilling machine, an impact drilling machine, a punching and grabbing cone, a rotary drilling machine, a Luoyang shovel with a tripod, a pneumatic drilling machine and the like. In the process of pile foundation treatment construction of part of existing railway lines, a construction area requires hard isolation and closed protection, the height limit is 3.8m, the width limit is 2.5m, and the construction requirement is carried out longitudinally along the line, so that large drilling equipment such as a rotary drilling machine, an impact drilling machine, a punching and grabbing cone, a rotary drilling machine and the like cannot meet site construction conditions and cannot carry out drilling operation in a narrow space and an existing electrified railway area due to the limitation of the construction area space; the existing small-sized drilling equipment is provided with a Luoyang shovel with a tripod support, wherein the position right below the vertex of the tripod support is aligned with the drilling position, but the Luoyang shovel is not suitable for drilling in an area close to a boundary line or other narrow spaces with limited height and width, and the Luoyang shovel is slow in drilling speed and low in drilling efficiency; the other small-sized drilling equipment, namely the pneumatic drilling machine can meet the construction conditions of narrow space under the general condition, but can only be suitable for small-aperture grouting hole guiding of about 10cm, and the limitation of the pneumatic drilling machine is that the aperture is too small, so that the pile foundation cannot effectively bear larger load. Therefore, when drilling in a narrow space and an existing electrified railway area, how to select a practical, safe and effective pile foundation drilling machine is a great difficulty in pile foundation construction.
Disclosure of Invention
The invention aims to overcome the defects of the traditional drilling machine and develop a walking type omnibearing rotary hydraulic pile foundation drilling machine which can be constructed in a narrow space and an existing electrified railway area.
The invention is realized by the following technical scheme:
the support column is hinged in front of the control chamber through a hinged support and two amplitude-changing oil cylinders, a slide rail is fixed on the support column and is hinged with a transmission chain, a chain wheel is fixed on the back of the sliding support and is buckled in the slide rail in a clamping mode, the chain wheel is connected with the transmission chain, a drilling power head is fixed in front of the sliding support, a spiral drill rod and a drill bit are connected below the drilling power head through a pin shaft, a hydraulic pump and a diesel engine are arranged behind the control chamber, the hydraulic pump is communicated with the amplitude-changing oil cylinders through a hydraulic pipe, the drilling power head is connected.
The invention adopts full hydraulic control and hydraulic transmission, all working parts can realize stepless speed change, the drilling power head can freely lift and descend under the drive of a transmission chain, the drill rod and the drill bit can rotatably drill under the drive of the power head, different drilling speeds can be adopted according to strata with different hardness, the adaptability to different soil qualities is strong, the drilling power head is flexible up and down, the drilling efficiency is high, the positioning is quick and accurate, the drilling capability is strong, the operation is convenient and flexible, the diesel engine power can meet the field independent operation, the application range is wide, the drilling system can rotate in all directions, no dead angle construction exists in the whole area, the occupied area of equipment is small, the operation radius is small, and the safety requirement of the existing railway construction and the requirement of construction in other areas.
