Abstract
A kind of forestry cable car dual-speed hydraulic system, the first hydraulic motor is interrelated synchronous with the second hydraulic motor, wherein：The A ends of first hydraulic motor and 33 mouthfuls of connections of two-position four-way valve, its B end is connected with 44 mouthfuls of 34 mouthfuls, three six-way valves of two-position four-way valve at the same time；The A ends of second hydraulic motor are connected with 31 mouthfuls of two-position four-way valve, 43 mouthfuls of three-position four-way valve at the same time, 34 mouthfuls of connections of its B end and two-position four-way valve；Control the first hydraulic motor, the second hydraulic motor to realize series connection and switching in parallel by two-position four-way valve, the first hydraulic motor is carried out by three-position four-way valve, the second hydraulic motor realizes rotating and stopping.Its advantage is to realize that hydraulic pressure provides power, and energy remote control, realizes that double speed exports.
Description
Technical field
The present invention relates to a kind of forestry cable car dual-speed hydraulic system.
Background technology
It is all only to be output to gear reducer with a hydraulic motor to be matched in the engineering machinery forestry cable car such as excavator, and by subtracting
Hawser is loosened in fast machine output tightening.And rotating speed can only be realized when using a hydraulic motor when main pump quantitatively exports
Input.Forestry cable car has in use to be walked away or is tensioned hawser and draw three functions of suspender, is made in the operating mode that walks away
What is used is quickly to walk away, and it is to use middling speed to draw suspender, and is then the big pulling force of low speed to be tensioned hawser operating mode.Reducing for this
Gear reducer controls, and under the requirement for realizing Remote Hydraulic control, hydraulic control can be used to coordinate two hydraulic motors to realize that double speed inputs.
The content of the invention
Realize that hydraulic pressure provides power it is an object of the invention to provide one kind, energy remote control, realizes the woods that double speed exports
Industry cable car dual-speed hydraulic system.
The solution of the present invention is such：
A kind of forestry cable car dual-speed hydraulic system, the first hydraulic motor is interrelated synchronous with the second hydraulic motor, wherein：First
The A ends of hydraulic motor and 33 mouthfuls of connections of two-position four-way valve, its B end at the same time with 34 mouthfuls, three six-way valves of two-position four-way valve
44 mouthfuls of connections；The A ends of second hydraulic motor be connecteds with 31 mouthfuls of two-position four-way valve, 43 mouthfuls of three-position four-way valve at the same time, its B end and
34 mouthfuls of connections of two-position four-way valve；By two-position four-way valve control the first hydraulic motor, the second hydraulic motor realize series connection with it is in parallel
Switching, carries out the first hydraulic motor, the second hydraulic motor realizes rotating and stopping by three-position four-way valve.
It is an advantage of the invention that realizing that hydraulic pressure provides power, energy remote control, realizes that double speed exports.
Brief description of the drawings
Fig. 1 is the principle of the present invention figure.
Embodiment
As shown in Figure 1, the first hydraulic motor 1 and the second hydraulic motor 2 are interrelated synchronous, wherein：First hydraulic motor 1
33 mouthfuls of A ends and two-position four-way valve 3 be connected, its B end 44 mouthfuls of companies with 34 mouthfuls, three six-way valves 4 of two-position four-way valve 3 at the same time
Connect；The A ends of second hydraulic motor 2 are connected with 31 mouthfuls of two-position four-way valve 3,43 mouthfuls of three-position four-way valve 4 at the same time, its B end and two
34 mouthfuls of connections of position four-way valve 3；By two-position four-way valve 3 control the first hydraulic motor 1, the second hydraulic motor 2 realize series connection with simultaneously
Connection switching, carries out the first hydraulic motor 1, the second hydraulic motor 2 realizes rotating and stopping by three-position four-way valve 4.
