Description
Technical Field
The invention relates to the technical field of pile foundation construction equipment, in particular to a rotary drilling rig with the coexistence of winch pressurization and oil cylinder pressurization and a transportation method thereof.
Background
At present, the rotary drilling rig can be divided into two types according to a pressurizing mode: a rotary drilling rig pressurized by an oil cylinder and a rotary drilling rig pressurized by a winch. The rotary drilling rigs adopting the two pressurizing modes have advantages and disadvantages respectively.
The oil cylinder is rigidly pressurized, so that the structural strength is high and the pressurizing degree is high; compared with the hoisting pressurization, the device occupies less space, and has simpler structure, safety and reliability; the failure rate is low, and the use and maintenance cost is low; the operation is simple and convenient.
The rotary drilling rig adopting the oil cylinder for pressurization cannot achieve the effect of pulse pressurization because the pressurization mode is rigid pressurization. When drilling, the reaction force transmitted to the stratum cannot be relieved, and particularly when drilling rocks, the impact force and vibration of the rock on the drilling tool cannot be absorbed and buffered. The mast and the machine body are easy to vibrate violently, the structural part is cracked and damaged, and the service life of the whole machine is shortened. The oil cylinder is pressurized, and the pressurizing stroke is short due to the structural characteristics of the oil cylinder, so that the requirements of the operation of the lower long pile casing cannot be met. Therefore, the rotary drilling rig adopting the oil cylinder for pressurization is more suitable for drilling operation of soft ground.
The winch pressurization mainly adopts the pulley block steel wire rope for pressurization, belongs to flexible pressurization, can achieve the effect of pulse pressurization through the tensile force of the steel wire rope, effectively relieves the reaction force generated by drilling rocks, reduces the impact on the mast, and prolongs the service life of the mast; the pressurizing stroke of the hydraulic pile can reach the full stroke of the mast, and the working operation of the lower pile casing can be met. Therefore, the hoisting pressurization is more suitable for drilling rock and the situation with the operation requirement of the lower casing.
The rotary drilling rig adopting winch pressurization comprises a winch, a steel wire rope and a pulley block, the steel wire rope needs to be disassembled in the transportation process of the whole machine, and the disassembling and assembling processes of the steel wire rope are quite complicated. Because the structure of the steel wire rope is relatively complex, the steel wire rope is a flexible body and is easy to interfere, collide and rub with other structural parts, the abnormal abrasion of the steel wire rope is caused, and potential safety hazards are generated in the working process. In addition, the steel wire rope is an easily worn part and needs to be maintained and replaced regularly, and the self cost and the later maintenance cost are higher than those of an oil cylinder pressurization mode. Furthermore, the steel wire rope has a limited load-bearing capacity and cannot withstand a large pressure.

When the rotary drilling rig is in a working state, if the rotary drilling rig works in a hoisting pressurization mode, the hoisting pressurization working mode can be entered only by detaching the pressurization oil cylinder 11, the pressurization oil cylinder upper fixing seat 10 and the pressurization oil cylinder lower fixing seat 13; if the rotary drilling rig works in an oil cylinder pressurization mode, the pressurization winch 2 can enter an oil cylinder pressurization working mode only by enabling the pressurization winch 2 to be in a floating mode state and enabling the pressurization winch 2 to rotate along with the telescopic action of the pressurization oil cylinder 11, and the purpose that the pressurization steel wire rope is not detached by adopting oil cylinder pressurization is achieved.
The invention also relates to a transportation method of the rotary drilling rig with the coexistence of winch pressurization and oil cylinder pressurization, which comprises the following steps: the pressurizing cylinder 11 is separated from the power head 16, the first wire rope 4 and the second wire rope 19 are in a loose state, the power head 16 is placed on the lower mast 20, and the upper mast 9 and the lower mast 20 are folded along the hinged point of the upper mast and the lower mast 3 respectively.
Specifically, the rotary drilling rig needs to go through four steps from the working state (shown in fig. 1) to the transportation state (shown in fig. 6).
In the first step, the second shaft 14 is removed, and the pressurizing cylinder 11 is separated from the power head 16.
And secondly, loosening the pressing plate of the rope pressing device 23, and detaching the second steel wire rope 19 at the fixed end of the rope pressing device 23 to enable the second steel wire rope 19 to be in a loose state.
Third, the pressurized winch 2 is rotated counterclockwise as shown in fig. 2, so that the first wire rope 4 is in a slack state.
Fourthly, the power head 16 is placed at the lowest point of the lower mast 20, the upper mast 9 and the lower mast 20 are folded along the hinge point of the upper mast and the lower mast 3 respectively, and the purpose of transporting and transferring the rotary drilling rig without disassembling a steel wire rope can be achieved.
