Background technology
Unit head in the rig through gear drive, drives the tool joint rotating normally by fluid motor-driven, drives following drilling tool rotation with this.Existing unit head is generally infinitely variable speeds, i.e. exportable one grade of rotating speed only, and this does not meet the requirement of modernized mechanical work.
The operating mode of rig is more abominable, and its part and structure all should be take simple, practicalities as design principles; Require to install and convenient disassembly, and for ease of maintenaince, be fit to open-air area and use.And all there is baroque limitation in the rig of the machine power head type of commonly using now, does not meet the maneuverability requirement of field work, need to be improved.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of two hydraulic motors drive-type gyrator is provided, it adopts two hydraulic motors, changes output torque and rotating speed by the connection in series-parallel state that changes two hydraulic motors, finally realizes many grades of rotating speed output functions of unit head, have simple in structure, reliable, advantage flexible to operation, and its make and maintenance cost low, strong adaptability, can adapt to abominable working environment, be specially adapted to infinite variable speed unit head.
According to technical scheme provided by the invention: two hydraulic motors drive-type gyrator is characterized in that: comprise control valve and be used for the first hydraulic motor and the second hydraulic motor to the unit head outputting power; Described control valve has A, B, four ports of C, D, and when control valve was positioned at left position, A port and B port formed and open circuit, and C port and D port form path; When control valve was positioned at right position, A port and C port formed path, and B port and D port form path; The A port of described control valve and the oil-in of described the first hydraulic motor are communicated with in-line, the oil-out of described the first hydraulic motor is communicated with the D port of control valve, the C port of described control valve is communicated with the oil-in of the second hydraulic motor, and the B port of the oil-out of the second hydraulic motor and described control valve all is communicated with return line.
The present invention compared with prior art, advantage is: the present invention adopts two hydraulic motors, change output torque and rotating speed by the connection in series-parallel state (namely passing through oil path control system) that changes two hydraulic motors, final many grades of rotating speed output functions that realize unit head have advantage simple in structure, reliable, flexible to operation, and its manufacturing and maintenance cost are low, strong adaptability can adapt to abominable working environment, is specially adapted to infinite variable speed unit head.

Catenation principle schematic diagram when Fig. 2 is the present invention's state in parallel (control valve is positioned at right position).
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in Figure 1 and Figure 2, two hydraulic motors drive-type gyrator of the present invention mainly contains control valve 1 and is used for forming to the first hydraulic motor 2 and second hydraulic motor 3 of unit head outputting power.
Described control valve 1 has A, B, four ports of C, D, and when control valve 1 was positioned at left position, A port and B port formed and open circuit, and C port and D port form path; When control valve 1 was positioned at right position, A port and C port formed path, and B port and D port form path.
The A port of described control valve 1 and the oil-in of described the first hydraulic motor 2 are communicated with in-line, the oil-out of described the first hydraulic motor 2 is communicated with the D port of control valve 1, the C port of described control valve 1 is communicated with the oil-in of the second hydraulic motor 3, and the B port of the oil-out of the second hydraulic motor 3 and described control valve 1 all is communicated with return line.
Concrete applicable cases of the present invention is as follows:
1, the first hydraulic motor 2 (see figure 1) of connecting with the second hydraulic motor 3
Stir control valve 1 and be in left position, it is obstructed that A port and B port form the fluid that opens circuit, C port and D port form path, the first hydraulic motor 2 and the second hydraulic motor 3 are series connection, the second hydraulic motor 3 is driven by the first hydraulic motor 2, the high rotating speed of the first hydraulic motor 2 outputs, low moment of torsion are finally realized the function that unit head is exported high rotating speed, hanged down moment of torsion.
2, the first hydraulic motor 2 and the second hydraulic motor 3 (see figure 2)s in parallel
Stir control valve 1 and be in right position, A port and C port form path, B port and D port form path, fluid enters and is divided into two-way from in-line: the one tunnel enters the oil-in of the second hydraulic motor 3 through A port and C port, drive the second hydraulic motor 3, again from the oil return opening of the second hydraulic motor 3 to return line; Another road directly enters the oil-in of the first hydraulic motor 2, drives the first hydraulic motor 2, goes out to return line from B port and D port again.In this process, fluid is realized the first hydraulic motor 2 and 3 parallel connections of the second hydraulic motor simultaneously to two hydraulic motor effects, and two hydraulic motors are exported the slow-speed of revolution, high moment of torsion, finally realizes the function of the unit head output slow-speed of revolution, high moment of torsion.
Concrete Application Example:
The initial flow 14.7L of fluid, the model of the first hydraulic motor 2 and the second hydraulic motor 3 all is J2K195, discharge capacity 0.195L/r calculates output speed and moment of torsion such as the following table (the gearratio i=59/21=2.81 between motor and the output main shaft 4) of unit head according to the hydraulic motor parameter of this specification.
