Ürün Açıklaması
GPF series crawler reverse cycle full hydraulic drilling machine adopts full hydraulic constant speed change, constant pressure and constant speed drilling, equipped with large diameter, low lift, and large displacement sand pump circulating mud. Drilling rig and mud pump are all driven by hydraulic motor. The drilling speed and circulating mud flow can be automatically adjusted according to the construction needs. Vacuum exhausting exhaust is more efficient than liquid filled exhaust. Carrying a self-propelled crawler chassis subverts the reverse circulation system which makes the movement more convenient and flexible, uses pump suction or air lift. The drilling efficiency is high, the hole quality is good, the power consumption is low, the bit life is long, and the use cost is low. This series of drilling rig has the advantages of high construction efficiency, good ground maneuverability, safe and convenient operation and maintenance, and high performance price ratio. It is mainly used in pile foundation construction of middle and large diameter, large depth and complex stratum, especially for sand, pebble and rock stratum construction. The diameter of the drilling rig is 4m, the deepest depth is 150m, and it can be used in the rock layer under the hardness of 100mPa. It is widely used for the construction of the pile foundation such as the land building, the borehole, the port wharf, the river, the river, the lake and the sea.
Main performance characteristics
Using full hydraulic constant speed change, constant pressure and constant speed drilling, equipped with large diameter, low lift, large displacement sand and stone pump circulating mud. Drilling rig and mud pump are all driven by hydraulic motor. The drilling speed and circulating mud flow can be automatically adjusted according to the construction needs. Carrying the self-propelled crawler chassis subverts the traditional reverse circulation slag system which makes the movement more convenient and more flexible, uses pump suction or air lift. The drilling efficiency is high, the quality of the holes is good, the power consumption is low, the bit life is long, and the cost is low. This series of drilling rigs has the advantages of high construction efficiency, good field mobility, safe operation and maintenance, and high comprehensive cost performance.
1. Power head
Full hydraulic drive, large torque, large lift configuration, strong operation ability, stable and reliable transmission performance. Using the motor of Bray Vinnie and other international brand power head reducer and Rexroth technology, the stepless speed regulation in the process of drilling can be realized. The speed and torque of the power head can be automatically adjusted according to the different strata, and the best working state can be achieved. Excellent performance and excellent performance can be achieved under any circumstances.
2, power head lifting oil cylinder
Using large bore oil cylinder to enhance power head and drilling tools, it has simple structure, large lifting force, stable and reliable performance, safe use and convenient maintenance. It can also realize the oil cylinder decompression or proper pressure drilling, greatly improving the perpendicularity and footage speed of the drilling hole.
3, hydraulic pump station and electrical control
The hydraulic pump station adopts the whole box type structure, which can be assembled and disassembled to facilitate the maintenance of the pump station. The pump station has full closed cover door and cover plate, and the electrical and hydraulic parts can be effectively protected. Electrical control has overload, overcurrent, overvoltage protection function, and is safe and reliable.
4, PLC monitoring and operating room
The PLC text monitor can display the main operating parameters and the cause of the failure of the system, and has the function of sound alarm. The operating room control console adopts the stainless steel panel, the control handle layout is reasonable and easy to operate. It can set and adjust the parameters of the rig speed and pressure on the operating table, the maintenance cost is low, the environment is comfortable, and the air conditioning equipment is equipped with the optional installation.
5. Automatic drilling function
The drilling machine has automatic drilling control system. It can set different axial pressure according to the formation conditions and keep the constant axial pressure. It reduces the requirements for the operators and improves the efficiency of the drill.
6, large particle sand stone pump without pole speed regulation
Equipped with large diameter, low lift, large displacement sand and stone pump circulating mud, good performance of the pebble, high slag discharge capacity, the use of variable hydraulic pump drive, can realize the sand and stone pump without pole speed control, efficient and energy-saving.
7. Vacuum pump
The use of large displacement water circulating vacuum pump, easy to use and maintain, vacuum evacuation efficiency is high.
8. Self-propelled crawler chassis
The chassis of the drill rig adopts a self-propelled crawler chassis, the ground specific pressure is small, the maneuverability of the site is strong, and the movement is convenient, which can meet the needs of the drilling machine in the difficult and complex working conditions.
9. Auxiliary disassembly of drill rod boom
The drilling rig is equipped with auxiliary mechanical crane arm. When the drill pipe is disassembled, the hoist arm works with the drill rod to carry on the hoisting, lifting drill rod and counterposition function. The drill rod is more convenient and more labor-saving, and the drill rod is dismantled and the labor strength is reduced.
10. Drilling tool
Large diameter and thick wall threaded joint drill rod, with special heat treatment and automatic submerged arc welding technology, high strength, long life, convenient and quick time saving and labor of thread connection and disassembly, optionally adding pressure of heavy hole bottom, ensuring verticality of hole forming, improving drilling efficiency and quality.
