Abstract
The utility model relates to a hydraulic apparatus of a drilling machine, which comprises an oil tank, an oil suction filter, a variable quantity plunger pump, a multi-way change valve, pipelines, an air filter, a hydraulic radiator and an oil return oil filter, wherein an oil suction pipe of the variable quantity plunger pump passes the oil suction filter to the oil tank through the pipelines, and oil discharge pipes reach the multi-way change valve and then respectively reach a rotating hydraulic motor and a pressurization lifting hydraulic motor; after the pressurization lifting hydraulic motor passes a balance valve, the two oil discharge pipes respectively pass through the hydraulic radiator and the oil return oil filter to the oil tank after merge. The utility model has simple structure and high work efficiency of high-pressure oil. When a power head rotates and the pressurization lifting hydraulic motor acts, the stability of the lifting / lowering of a drill stem can be ensured.
Description
The utility model relates to a kind of rig hydraulic means.
At present, its system complex of rig hydraulic means, the hydraulic oil work doing efficiency is low, especially when unit head rotation and pressurization/lifting hydraulic motor, can not guarantee the stationarity of drilling rod lifting/decline.
Its purpose of the utility model is: a kind of rig hydraulic means is provided, and it is simple in structure, hydraulic oil work doing efficiency height, the stationarity of assurance drilling rod lifting/decline when unit head rotation and the action of pressurization/lifting hydraulic motor.
The utility model is achieved in that
A kind of rig hydraulic means, comprise: fuel tank, oil suction cleaner, Variable plunger pump, multiple directional control valve, pipeline, air filter, hydraulic pressure radiator, oil return oil filter, it is characterized in that: the fuel sucking pipe of its Variable plunger pump by the oil suction cleaner by pipeline to fuel tank, its flowline is to multiple directional control valve and promote hydraulic motor to rotary hydraulic motor, pressurization respectively, and pressurization promotes after two-way converges behind the logical equalizing valve of hydraulic motor successively through hydraulic pressure radiator, the logical fuel tank of oil return oil filter.
Between its Variable plunger pump and the multiple directional control valve anti-shock pressure meter is set, its fuel tank is communicated with air filter.
Described Variable plunger pump is the axial plunger pump of bringing onto load sensing flow rate pressure adjuster, and its multiple directional control valve is that manual load-sensitive proportional multi-path post is to valve.
The utility model hydraulic means: simple in structure, hydraulic oil work doing efficiency height, the stationarity of assurance drilling rod lifting/decline when unit head rotation and the action of pressurization/lifting hydraulic motor.
Elaborate below in conjunction with embodiment and accompanying drawing:
Fig. 1: the utility model structural representation.
Its structure of the utility model is as shown in Figure 1: a kind of rig hydraulic means, comprise: fuel tank 12, oil suction cleaner 1, Variable plunger pump 2, multiple directional control valve 4, pipeline 3, air filter 9, hydraulic pressure radiator 10, oil return oil filter 11, it is characterized in that: the fuel sucking pipe of its Variable plunger pump 2 by oil suction cleaner 1 by pipeline 3 to fuel tank, its flowline is to multiple directional control valve and respectively to rotary hydraulic motor 6, pressurization lifting hydraulic motor 7, and pressurization lifting hydraulic motor 7 logical equalizing valve 8 back two-way lead to fuel tank through hydraulic pressure radiator 10, oil return oil filter after converging successively.
Above-mentioned Variable plunger pump adopts that bringing onto load sensing flow--the axial plunger pump of pressure regulator, its multiple directional control valve 4 are that manual load-sensitive proportional multi-path post is to valve.
Between Variable plunger pump and the multiple directional control valve 4 anti-shock pressure meter 5 is set, its fuel tank is communicated with air filter.
Way reversing valve adopts manual load-sensitive proportional multi-path reversing valve more than above-mentioned;
It all is that the negative hydraulic means of low discharge is finished that rig uses each the final action of its rig of this hydraulic means, this hydraulic means adopts the little induction variable system of high pressure device, it is not only simple in structure, when a Variable plunger pump 2 during to above-mentioned two motor fuel feeding, for what of each motor fuel delivery irrelevant with the load of two motors, only relevant with the handle aperture of multiple directional control valve 4; Per moment of system, required flow finally showed as a concrete pressure signal--promptly being delivered to the flow of Variable plunger pump 2--pressure regulator makes the swash plate of Variable plunger pump put certain angle, thereby makes the output oil mass of oil pump reach desirable value; When if system does not need flow (promptly two handles are put in meta), though motor still rotates with rated speed, but this moment, the swash plate angle of Variable plunger pump was 0, this oil pump does not have flow output, motor is in low load condition, equally, this oil pump is supplied with the total and required flow of system of oil mass and is complementary, because the hydraulic oil that this oil pump is supplied with has been maximally utilised by system, so also reduced the heating of system, the power output of motor is changed with load variations, so, having saved energy, system brings up to 20Mpa from rated pressure 14Mpa usually.
