Abstract
The utility model discloses a hydraulic system of a fork truck on vehicle. The hydraulic system comprises a twin interlocked motor and a plunger pump, wherein an output pipeline of the plunger pump is connected to the twin interlocked motor through a balance valve and a magnetic valve; a flow distributing valve is connected between the plunger pump and the twin interlocked motor; a gear pump connected with a motor of the fork truck is connected with a multiway valve through a monostable valve; the multiway valve is connected with a lateral-moving oil cylinder, a plurality of inclined oil cylinders and a plurality of lifting oil cylinders of the fork truck; hydraulic locks are connected between the inclined oil cylinders and the multiway valve as well as between the lifting oil cylinders and the multiway valve; and the gear pump is connected with a steering motor of the fork truck through a steering device. When in field work, the hydraulic system can cope with such execrable working conditions as miry roads, concave-convex grounds, stony soil, complicated road surfaces and the like, and realize the functions of cargo lifting, lateral-moving and forward-backward bending.
Description
Technical field
The utility model relates to fork truck hydraulic efficiency pressure system field, is specially a kind of with car fork truck hydraulic efficiency pressure system.
Background technology
Fork truck is the visual plant of modern goods transport and loading and unloading.Existing fork truck substantially all is fixed on a local work, and can not the long distance of actv. move, during particularly to operation in the open air, needed forklift truck properties under the bad working environments such as muddy road surface, concavo-convex road surface, chisley soil earth, complex road surface, if by general driving bridge-type or motor-driven wheeled fork truck, the poor-performing of its performance.
The utility model content
The purpose of this utility model provides a kind of with car fork truck hydraulic efficiency pressure system, can't adapt to the complex work problem of environment with the forklift truck properties that solves prior art.
In order to achieve the above object, the technical scheme that the utility model adopted is:
With car fork truck hydraulic efficiency pressure system, include twin interlocking motor, and with forklift engine bonded assembly plunger pump, it is characterized in that: the delivery conduit of described plunger pump is respectively by a plurality of balance cocks that are connected in parallel to each other, a plurality of electromagnetic valves that are connected in parallel to each other insert twin interlocking motor, also have access to flow divider valve on the delivery conduit between described plunger pump and the twin interlocking motor, also comprise and forklift engine bonded assembly gear type pump, described gear type pump is connected with a multiway valve by Monostable valve, control cock piece in the described multiway valve respectively separately with the sidesway oil cylinder of fork truck, a plurality of dump rams, a plurality of lift oil tanks connect, described dump ram, also be connected to hydraulic lock respectively between the control cock piece in lift oil tank and its cooresponding multiway valve, described gear type pump also is connected with the steering motor of fork truck by deflector.
Described with car fork truck hydraulic efficiency pressure system, it is characterized in that: described plunger pump also is connected to shuttle valve, and the delivery conduit of described shuttle valve is connected to compression indicator.
The utility model adopts hydrostatic closed system, link to each other with driving engine with plunger pump, come the control system flow by the swash plate angle that changes plunger pump, thereby the speed of control car load, the rotating speed of driving engine feeds back to again on the controller of plunger pump simultaneously, just can control the aperture at the swash plate angle of the throttle of driving engine and pump like this with a pedal, thereby also realize the anti-flame-out of driving engine.On fork truck, is furnished with the swash plate angle that a pedal can the direct control plunger pump again, even can realize also that at maximum position the swash plate angle of plunger pump makes zero the emergency braking when realizing walking in Das Gaspedal.Plunger pump links to each other with twin interlocking motor, and is furnished with a flow distributing valve on steering swivel system, and therefore, under bad working environments, fork truck can slip-skid prevention and good turning to and climbing function.
When the utility model is worked in the open air, can handle a situation with ease to bad working environments such as muddy highway, concavo-convex ground, chisley soil earth, complex road surfaces, and can realize hoisting of goods, sidesway and swing function.
Description of drawings
Fig. 1 is the utility model hydraulic system principle figure.
The specific embodiment
As shown in Figure 1.With car fork truck hydraulic efficiency pressure system, include twin interlocking motor 3, and with forklift engine 1 bonded assembly plunger pump 2, the delivery conduit of plunger pump 2 is respectively by two balance cock 10-1 that are connected in parallel to each other, 10-2, two electromagnetic valves that are connected in parallel to each other 11,12 insert twin interlocking motor 3, also have access to flow divider valve 4 on the delivery conduit between plunger pump 2 and the twin interlocking motor 3, also comprise and forklift engine 1 bonded assembly gear type pump 15, gear type pump 15 is connected with a multiway valve 21 by Monostable valve 16, control cock piece in the multiway valve 21 respectively separately with the sidesway oil cylinder 5 of fork truck, two dump rams 6,7, two lift oil tanks 8,9 connect, dump ram 6,7, lift oil tank 8,9 and its cooresponding multiway valve in the control cock piece between also be connected to hydraulic lock 19 respectively, 20, gear type pump 15 also is connected with the steering motor 18 of fork truck by deflector 17.Plunger pump 2 also is connected to shuttle valve 13, and the delivery conduit of shuttle valve 13 is connected to compression indicator 14.
In the utility model, running gear uses plunger pump and twin interlocking motor to form the hydrostatic pressure system of an enclosed.System is succinct, controls its flow size by changing plunger pump swash plate angle, gives full play to the performance of driving engine.When forklift workability, can realize the infinite speed variation of fork truck and good travel, deceleration and stopping performance.Simultaneously, fork truck can be realized hoisting of pallet fork, the sidesway of door frame, and the swing of door frame, these actions all are to be realized by the hydraulic efficiency pressure system that another gear type pump drives.Compare with common wheeled fork truck, this hydraulic efficiency pressure system with the car fork truck can realize infinite speed variation, can obtain lower stabilized speed, and rotor inertia is little, when front and back wheel limits its performance because of adhesive ability changes, can realize the shunting voluntarily of part driving power; There is not the manipulation that forward and reverse craspedodrome of wheel or turning can be normal and continuous; Can adopt the CD-ROM drive motor of different size and the wheel in different wheels footpath; All drive wheels are all brought into play certain tractive force all the time, even tire is equipped with the also unlikely tractive characteristic that influences of deflection; The angle that can climb is more than or equal to 30%; Have slip-skid prevention function and good cornering properties; The full landform of full wheel drives, and possesses cross-country traveling ability, can overcome local road barrier and because complex road condition causes the deflection on the different directions and degree between the whole or wheel of vehicle.
Since simple for structure, tare is reduced; Each element mutual alignment does not have strict demand, can make compact conformation, good looking appearance, arrangement convenience.
