Abstract
The invention discloses a dump truck lifting system. The dump truck lifting system comprises an oil tank, an oil pump, a limit valve and a lifting oil cylinder. The oil tank is communicated with the lifting oil cylinder, and both ends of the limit valve are communicated with the outlets of the oil tank and the oil pump respectively. The dump truck lifting system achieves control of up and down of a dump truck by directly controlling fluid of hydraulic pipes, therefore, the up and down speeds can be directly sensed, reliable operation control and rapid system response can be achieved, system troubleshooting can be facilitated and low comprehensive cost can be obtained.
Description
Technical field
The present invention relates to automobile technical field, especially a kind of self-unloading vehicle lifting system.
Background technology
Thereby most normal lifting and the decline that adopts braking gas tank internal gas pressure control lifting valve to realize compartment of current domestic self-unloading vehicle lifting system, it is that control response lags behind that this mode exists drawback, controlling tracheae easily reveals, integrated cost is high, cannot direct feel and control the lifting speed of self-discharging carriage.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of self-unloading vehicle lifting system, simple in structure, intuitive and reliable.
In order to realize foregoing invention object, the invention provides following technical scheme: a kind of self-unloading vehicle lifting system, comprise fuel tank, oil pump, limit valve and elevating ram, fuel tank is communicated with elevating ram through oil pump; The two ends of limit valve are communicated with fuel tank and oil pump outlet respectively.
Further, also comprise check valve, the arrival end of this check valve is communicated with oil pump outlet, and exit end is communicated with this elevating ram.
Further, this limit valve is communicated with the exit end of this check valve.
Compared with prior art, the present invention has the following advantages: thereby directly by the fluid control of hydraulic tubing being realized to lifting and the decline of controlling self-discharging carriage.Can direct feeling lifting and the speed of decline by this mode, handle control reliable, faster system response, and the system failure easily investigates, integrated cost is low.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention;
Fig. 2 is structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, describe the present invention, the description of this part is only exemplary and explanatory, should not have any restriction to protection scope of the present invention.
A kind of self-unloading vehicle lifting system as illustrated in fig. 1 and 2, comprises fuel tank 1, oil pump 2, limit valve 4 and elevating ram 3, and fuel tank 1 is communicated with elevating ram 3 through oil pump 2; The two ends of limit valve 4 are communicated with fuel tank 1 and oil pump 2 outlets respectively.
Hoisting system of the present invention also comprises check valve 5, and the arrival end of this check valve 5 is communicated with oil pump 2 outlets, and exit end is communicated with this elevating ram 3.This limit valve 4 is communicated with the exit end of this check valve 5.
Direct control system oil circuit of the present invention, control system is simple, controls effect intuitive and reliable.Cancelled traditional, pneumatic mode, thus directly by hydraulic tubing fluid control realize and control lifting and the decline of self-discharging carriage.Can direct feeling lifting and the speed of decline by this mode, handle control reliable, faster system response, and the system failure easily investigates, integrated cost is low.
