Abstract
The invention discloses a cab lifting system, comprising a fuel tank, a fuel pump, a fuel cylinder and a connecting fuel tube, wherein the fuel tank, the fuel pump and the fuel cylinder are communicated by the connecting fuel tube; the fuel cylinder comprises a left fuel cylinder and a right fuel cylinder; and the left fuel cylinder and the right fuel cylinder are respectively arranged below a left longitudinal beam and a right longitudinal beam at the lower part of the cab. The cab lifting system has the main application and the advantages that dual-cylinder fuel liquid transmission is adopted, and a motor driven pump is arranged. The cab lifting system has simple structure can be used for realizing the synchronous and quick turnover of an overweight four-door cab, and has a large lifting angle up to 31.8 degrees. In addition, the cab lifting system can be matched with the cab in an elastic suspension way, thereby improving the impact resistance and the smoothness of the cab, and improving the operation comfort of a driver.
Description
Technical field
The present invention relates to the technology that a kind of fire extinguishing tanker is manufactured, be specifically related to a kind of operator's compartment hoisting system.
Background technology
General operator's compartment adopts the single cylinder lifting, promptly has only an elevating ram, and what oil cylinder adopted is the fluid transmission.For overweight operator's compartment, the serious crooked situation of operator's compartment appears in single cylinder lifting meeting; And the lifting difficulty, lifting speed is slow, and lift height is also limited.The maximization of fire extinguishing tanker is a developing direction at present, and the operator's compartment majority of fire extinguishing tanker is taked the broad cab structure of four door, and the operator's compartment bottom surface is large, and operator's compartment weight is huge.
Summary of the invention
The present invention is directed to the deficiency that prior art exists, the technical matters that solve is: provide a kind of operator's compartment that makes overweight four door fire extinguishing tanker can synchronous lifting, and then the system of lifting fast.
The present invention is for solving the problems of the technologies described above, the technical scheme of taking is: a kind of operator's compartment hoisting system, comprise fuel tank, oil pump, oil cylinder and be connected oil pipe, be communicated with by connecting oil pipe between fuel tank, oil pump and the oil cylinder, oil cylinder is set to left and right oil cylinder and is separately positioned on below the left and right longeron in operator's compartment bottom.
Further, described oil pump also is communicated with motor-drive pump is in parallel by connecting oil pipe.
Further again, the power knob of described motor-drive pump is arranged near the oil pump.
The present invention compared with prior art, beneficial effect is: adopts the transmission of twin-tub fluid, mated motor-drive pump, and simple in structure, can make synchronous, the upset fast of overweight four door operator's compartment, the angle of lifting is convenient to the driving engine under the operator's compartment and the maintenance of related accessories up to 31.8 degree.Existing single cylinder lifting operator's compartment difficulty and the crooked serious problem of operator's compartment have been eliminated, the service life of having improved operator's compartment greatly.Chaufeur can be realized driver's cab turnover by power knob, has alleviated chaufeur labour intensity, makes lifting operator's compartment light and fast.Can mate with the operator's compartment elastic mounting in addition, improve operator's compartment impact resistance and ride comfort, strengthen the operation comfort of chaufeur.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Wherein: left oil cylinder 1, right oil cylinder 2, oil pump 3, motor-drive pump 4, fuel tank 5, connection oil pipe 6.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is described in further detail.
See shown in Figure 1, a kind of operator's compartment hoisting system, comprise fuel tank 5, oil pump 3, oil cylinder and be connected oil pipe 6 that be communicated with by connecting oil pipe 6 between fuel tank 5, oil pump 3 and the oil cylinder, oil cylinder is set to left and right oil cylinder 1,2 and is separately positioned on below the left and right longeron in operator's compartment bottom.
In order to improve lifting speed, alleviate the labour intensity of manual pump oil, take to set up the mode of motor-drive pump oil.Oil pump 3 also is communicated with motor-drive pump 4 parallel connections by connecting oil pipe 6.Guaranteed not have under the situation of power supply, also can finish the lifting of operator's compartment by manual pump oil mode.
During assembling, left oil cylinder 1 arranged side by side and right oil cylinder 2 are placed on the right and left below the rear cabin respectively, and connect to ground by support; The piston rod of left side oil cylinder 1 and right oil cylinder 2 is connected with operator's compartment by support.
Principle of work: (one) lifting process: the change-over valve of oil pump 3 is in the lifting state, promptly is the switch of change-over valve is pushed oil pump 3 two-chamber oil-out positions, looks particular case then, both can take manual mode pump oil, also can take electronic mode pump oil.Oil pump 3 two-chambers are fuel-displaced under this state, give left oil cylinder 1 epicoele fuel feeding and cavity of resorption fuel feeding through connecting oil pipe 6, give right oil cylinder 2 epicoeles and cavity of resorption fuel feeding through connecting oil pipe 6 simultaneously, and left oil cylinder 1 and right oil cylinder 2 produce the synchronous lifting power that makes progress same.Because operator's compartment has certain rigidity, thereby realize the operator's compartment synchronous lifting.(2) decline process: the change-over valve of oil pump 3 is in the falling state, looks particular case then, both can take manual mode pump oil, also can take electronic mode pump oil.These state oil pump 3 single chambeies are fuel-displaced, give left oil cylinder 1 epicoele fuel feeding and give right oil cylinder 2 epicoele fuel feeding by connecting oil pipe 6, by connecting oil pipe 6 oil of the cavity of resorption of left oil cylinder 1 and right oil cylinder 2 carried dump pump 3.Therefore, under the tension of operator's compartment gravity and left oil cylinder 1, right oil cylinder 2, realized that promptly operator's compartment falls after rise synchronously.
For convenient to operation, the power knob of motor-drive pump 4 is arranged near the oil pump 3.
In addition, take the fire extinguishing tanker of elastic mounting damping for operator's compartment, the vehicle that suspends before particularly installing, the fit on native system, the rear portion of operator's compartment is connected with the piston rod of left oil cylinder 1 and right oil cylinder 2, has played damping, shock proof effect simultaneously.
The present invention adopts the transmission of twin-tub fluid, mated motor-drive pump, and is simple in structure, can make overweight four door operator's compartment synchronously, upset fast, the angle of lifting is up to 31.8 degree, is convenient to the driving engine under the operator's compartment and the maintenance of related accessories.Existing single cylinder lifting operator's compartment difficulty and the crooked serious problem of operator's compartment have been eliminated, the service life of having improved operator's compartment greatly.Chaufeur can be realized driver's cab turnover by power knob, has alleviated chaufeur labour intensity, makes lifting operator's compartment light and fast.Can mate with the operator's compartment elastic mounting in addition, improve operator's compartment impact resistance and ride comfort, strengthen the operation comfort of chaufeur.
