The technical problems to be solved in the utility model provides a kind of action that can realize the big arm tipping bucket of wheel loader, turns to control, the hydraulicefficiency telecontrol system of Throttle Opening Control, brake control, gear control.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme: comprise a hydraulic oil container and a manual operating grip, described hydraulic oil container is given the pressure-gradient control valve fuel feeding by steering pump, described pressure-gradient control valve is given direction machine fuel feeding, described direction machine links to each other with turning to executive component, described manually-operable handle is controlled big arm tipping bucket executive component by the multiplexed operation valve, also comprise and turn to control module, the operation sequential module, bypass valve and throttle driver module, the gear driver module, the brake driver module, at described pressure-gradient control valve with turn between the executive component to be provided with and turn to control module, described steering pump connects described bypass valve, described bypass valve is by the throttle driver module, the gear driver module, the brake driver module respectively with throttle, gear, the brake executive component links to each other, and between described bypass valve and the multiplexed operation valve operation sequential module is set.Described control module, bypass valve, brake driver module, gear control module, throttle driver module, the operation sequential module of turning to controlled by remote control equipment respectively.
Preferably, bypass valve links to each other with described throttle driver module, gear driver module, brake driver module respectively by the multichannel pipe joint.
Preferably, throttle driver module, gear driver module, brake driver module are respectively and oil return circuit is set between the hydraulic oil container.
Preferably, the ratio driver module, turn between control module and the hydraulic oil container oil return circuit be set.
The beneficial effects of the utility model are: by adopting electromagnetic valve group in current, and increase electrical equipment remote control equipment, realize the remote control operation of wheel loader, make the working environment of workers that significant improvement arranged, peformance margin also significantly improves, in addition, former car operation system is not destroyed, and can switch manually and remotely-controlled operation by the diverter switch on the remote control equipment.This design improvement cost is few, does not change the outward appearance of car load, and benefit is big.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
Fig. 1 is the schematic diagram of the utility model wheel loader remote manual control dual operation hydraulic system.
Fig. 2 is a wheel loader fluid-link steering schematic diagram among Fig. 1.
Fig. 3 is a wheel loader working hydraulic pressure schematic diagram among Fig. 1.
Embodiment
The designed hydraulic scheme of the utility model is to carry out hydraulic system on the former vehicle hydraulic system basis and improve not destroying.Can be implemented in and carry out turning to, advance, retreating and wheel loader proper functioning such as the upset action of the hoisting of big arm, decline and tipping bucket on the remotely-controlled operation panel by increasing electro-hydraulic control valve and some control modules etc. wheel loader, and former car operation system can independent operating, and remote handling system and manual operation system do not disturb mutually.
Fig. 2 is a wheel loader fluid-link steering schematic diagram.Hydraulic oil container is given the steering pump fuel feeding by oil purifier, and steering pump is given the pressure-gradient control valve fuel feeding again, and this pressure-gradient control valve when promptly not having go to action, is given multiplexed operation valve fuel feeding when normality, after go to action is arranged, gives the direction machine or turns to the control module fuel feeding.When the switch of remote control equipment switched to remote state, it was electric to turn to control module to get, and pressure-gradient control valve is turned to the control module fuel feeding, drove with this and turned to executive component steering hydraulic cylinder action, the final action that realizes or turn right.When the switch of remote control equipment switched to manual state, pressure-gradient control valve was given direction machine fuel feeding, thus the action that realizes or turn right.Turn to control module electric and outage are by the control of electrical equipment remote control equipment, thereby realized the remote control that turns to.Pressure-gradient control valve is the hydraulic control component that generally adopts in the big-and-middle-sized loading machine steering system, at loader and development product, and it and load feedback all-hydraulic steering gear, steering pump composition all hydraulic pressure steering-gear.
