Embodiment
In the technical program, the start and stop of main drum 4 and loose drum 5 are respectively by hydraulic motor A2 and the hydraulic motor of its end face
B7 controls, and is no longer controlled by manual or liquid braking device device.Equipped with brake inside hydraulic motor A2 and hydraulic motor B7,
For normally closed type piece-type brake, controlling to open by valve block integrated on hydraulic motor, minimum unlatching pressure is 1.8MPa.Hydraulic pressure
During winch work, hydraulic motor oil-in, when oil pressure is more than 1.8MPa, brake is opened, and reel is started working；Hydraulic wireline winch stops
Time only, oil pressure is less than 1.8MPa, and brake is closed thus locked reel.
During work, motor drives hydraulic pump 10 to be converted to liquid from fuel tank oil suction, the mechanical energy of 10 motor of hydraulic pump
The pressure energy of body.
Left side oil circuit, hydraulic medium enters hydraulic motor B7, hydraulic motor by pipeline through choke valve A17, reversal valve A15
Hydraulic energy transfer is mechanical energy by B7, and brake 6 is opened, and loose drum 5 is started working, and at this moment in Fig. 2, left side oil circuit work provides
Pressure, oil circuit reversal valve B16 commutation in right side makes hydraulic oil by flowing to reversal valve A15 at Fig. 2 dotted line, passes through with throttle valve A 17
Hydraulic oil simultaneously for hydraulic motor B7 provide pressure.
The right oil circuit, hydraulic medium enters hydraulic motor A2, hydraulic motor by pipeline through choke valve B18, reversal valve B16
Hydraulic energy transfer is mechanical energy by A2, and brake 3 is opened, and main drum 5 is started working, and at this moment in Fig. 2, right side oil circuit work provides
Pressure, the real hydraulic oil of left side oil circuit reversal valve A15 commutation, by flowing to reversal valve B16 at Fig. 2 dotted line, passes through with choke valve B18
Hydraulic oil simultaneously for hydraulic motor A2 provide pressure.
The technical program employs double high-torque hydraulic motor and controls the start and stop of major-minor cylinder respectively.Due to high-torque hydraulic
The employing of motor, in the case of it can make scraper volume ratio existing 55KW scraper little nearly 1/3rd, scraper pull strength is average
Up to 5000Kg (55KW scraper average pull strength 3500KG), and use hydraulic motor, make scraper stable working, nothing impact, its
Speed can be able to be applied and various mining sites with infinitely variable speeds.Utilize electric hydraulic control, braking mechanism can be substituted, also may be used simultaneously
So that putting rope reel to keep the resistance of certain limit interior (by hydra-electric control), steel cable keeps certain tensile force, can subtract
The phenomenon of few steel cable disorder cable.
This hydraulic motor A2 and hydraulic motor B7 by moment of torsion after primary speed-down up to 9500N.M, can be at 20～80 revs/min
Stepless time adjustment in the range of clock, it is adaptable to various complicated mining site situations, and changing without conventional hardware, it is ensured that digging efficient
Rate.
When a motor traction, another hydraulic motor can be controlled in certain range of resistance, it is ensured that put steel wire
End also has certain pulling force, to prevent the steel wire rope will not snarling.
