Problems solved by technology

[0002] At present, most domestic dump truck lifting systems use the air pressure in the brake gas tank to control the lifting valve to realize the normal lifting and lowering of the cabin. The disadvantages of this control method are that the control response is lagging, the control air pipe is easy to leak, the overall cost is high, and it is not intuitive. Feel and control the lifting speed of the dump car

Embodiment Construction

[0010] The present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the present invention.

[0011] Such as figure 1 with 2 The illustrated dump truck lifting system includes an oil tank 1, an oil pump 2, a limit valve 4, and a lifting cylinder 3. The oil tank 1 is connected to the lifting cylinder 3 via the oil pump 2; the two ends of the limit valve 4 are respectively connected to the oil tank 1 is connected to the outlet of the oil pump 2.

[0012] The lifting system of the present invention also includes a one-way valve 5, the inlet end of the one-way valve 5 is in communication with the outlet of the oil pump 2, and the outlet end is in communication with the lifting cylinder 3. The limit valve 4 communicates with the outlet end of the one-way valve 5.

[0013] The invention directly controls the oil circuit o...

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 [0001] The invention relates to the technical field of automobiles, in particular to a dump truck lifting system. Background technique [0002] At present, most domestic dump truck lifting systems use the air pressure in the brake cylinder to control the lift valve to realize the normal lifting and lowering of the car. The disadvantage of this control method is that the control response is lagging, the control air pipe is easy to leak, the overall cost is high, and it is not intuitive Feel and control the lifting speed of the dump truck. Summary of the invention [0003] Aiming at the shortcomings of the prior art, the present invention proposes a dump truck lifting system with simple structure, intuitiveness and reliability. [0004] In order to achieve the above-mentioned purpose of the invention, the present invention provides the following technical solutions: a dump truck lifting system, including an oil tank, an oil pump, a limit valve, and a lifting cylinder....
