Abstract
The utility model relates to a double-pump hydraulic system of a full-hydraulic crawler-type cutting drilling machine. The hydraulic system is the double-pump hydraulic system, and comprises a pump I, a pump II and an engine, wherein the pump I and the pump II are driven by the engine; an oil conveying port of the pump I is connected with oil supply pipelines of a cutting motor and a feeding motor through a main valve; an oil conveying port of the pump II is connected with an oil supply pipeline of a hydraulic motor of an air compressor system through a solenoid valve; the pump I is a variable pump; the pump II is a quantitative pump; the air compressor motor is a constant displacement hydraulic motor. The hydraulic system adopts the double-pump hydraulic system, and a cutting and drilling system and the air compressor system are separated and are not interfered mutually, so that stable working air volume can be provided, deslagging can be guaranteed to be stable and smooth, the delay of work efficiency and the waste of rod breakage due to drilling jamming caused by unsmooth deslagging are reduced, and the stability and the safety of operation are ensured; the air compressor is driven by the constant displacement hydraulic motor instead of a mechanical engine driving method, so that the difficult problem of replacement and maintenance of a belt is well solved.
Description
Technical field
The utility model relates to a kind of drilling rig power plant, particularly a kind of pump hydraulic system of all hydraulic caterpillar cutting drill.
Background technology
The hydraulic system of all hydraulic caterpillar cutting drill using is in the market all single pump hydraulic system substantially, the type of drive of air compressor machine or employing driven by engine (mechanical type) or employing hydraulic motor drive, and these two kinds of modes exist as follows compared with distinct issues:
1. adopt driven by engine to change belt more frequent and very inconvenient;
2. adopt hydraulic motor to drive, owing to being single-pump system or variable system, the air output of air compressor machine can diminish greatly because hydraulic system load becomes, work air quantity is unstable, cause that deslagging is unstable, operation has some setbacks, often occur by " kelly bit freezing ", frequent kelly bit freezing there will be disconnected bar or off-axis, puts to no little inconvenience and loses to user.
Utility model content
The technical problems to be solved in the utility model is: design a kind of pump hydraulic system of all hydraulic caterpillar cutting drill, to overcome the existing deficiency of above-mentioned prior art.
The technical scheme that the utility model is taked is: a kind of pump hydraulic system of all hydraulic caterpillar cutting drill, described hydraulic system is pump hydraulic system, comprise pump I, pump II and motor, described pump I and pump II are by driven by engine, the oil transportation mouth of described pump I is communicated with the oil feed line of cutting motor and feeding motor through main valve, and the oil transportation mouth of described pump II is communicated with the oil feed line of the hydraulic motor of air compressor system through electromagnetic valve.
Its further technical scheme is: described pump I is variable pump, and described pump II is constant displacement pump, and described air compressor machine motor is constant displacement hydraulic motor.
Owing to adopting technique scheme, the pump hydraulic system of a kind of all hydraulic caterpillar cutting drill of the utility model has following beneficial effect:
1. because hydraulic system of the present utility model adopts pump hydraulic system, cutting and drilling system separate with air compressor system, do not interfere with each other, constant displacement hydraulic motor used for air compressor provides pressure oil-source by independent constant displacement pump, be not subject to other load effect, guarantee that air compressor machine can provide stable work air quantity, guarantee that deslagging stablizes unobstructed, do not reduce because deslagging does not freely cause dally over one's work efficiency and disconnected bar of bit freezing and waste, both stability and the safety of operation had been guaranteed, improve again operating efficiency, reduced the loss causing because air quantity is unstable simultaneously;
2. drive because the air compressor machine of the utility model adopts constant displacement hydraulic motor, replace mechanical driven by engine mode, it is easier, safer that the structure of driven by engine air compressor machine is changed belt relatively, thereby solve preferably a difficult problem for belt replacing maintenance.
The technical characterictic of the pump hydraulic system of a kind of all hydraulic caterpillar cutting drill below in conjunction with drawings and Examples to the utility model is further described.
