Description
Technical field
The present invention relates to a kind of cab of heavy truck hydraulic lifting technology, be related specifically to a kind of cab of heavy truck hydraulic lifting radial plunger pump.
Background technology
Heavy truck, when needs maintain or keep in repair electromotor, generally uses hydraulic system by driver's cabin lifting so that maintaining or maintenance operation.Prior art cab of heavy truck hydraulic lifting mechanism generally uses single-plunger type manual pump, or torch integrated single-plunger type pump, or single-plunger type manual pump adds the combination of electric gear pump.The subject matter that single-plunger type manual pump exists is that operator's labor intensity is big, pulse is relatively big, poor stability and the shortcoming such as speed is slow.And the subject matter that electric gear wheel pump exists is requirement power of motor compared with big, pulse compared with the shortcoming such as big, poor stability is fragile and manufacturing cost is higher.The problems such as obviously, it is big that prior art cab of heavy truck hydraulic lifting mechanism also exists labor intensity, and pulse is relatively big, poor stability, speed are slow and manufacturing cost is higher.
Summary of the invention
The problems such as the labor intensity existed for prior art cab of heavy truck hydraulic lifting mechanism is big, pulse is relatively big, poor stability, speed are slow and manufacturing cost is higher, the present invention proposes a kind of cab of heavy truck hydraulic lifting radial plunger pump.Cab of heavy truck hydraulic lifting radial plunger pump of the present invention includes the pump housing, stator, rotor, oil distribution casing and reversal valve；It is uniformly arranged in the radial direction with plunger unit at rotor；Stator is arranged with rotor eccentricity；Oil distribution casing is arranged on rotor center, is provided with oil inlet passage and oil discharge passage and connects external pipeline respectively；Described reversal valve is arranged on external pipeline, can switch over the turnover oil pipe line of cab hoisting cylinder；Described plunger unit includes plunger and spring, and spring is arranged between the bottom outlet of plunger and plunger hole root step.
Further, the plunger unit quantity of cab of heavy truck hydraulic lifting radial plunger pump of the present invention is more than three groups.
Further, the rotor of cab of heavy truck hydraulic lifting radial plunger pump of the present invention is connected by gear or belt pulley rocking-turn handle, or connection has motor rotary shaft.
The Advantageous Effects of cab of heavy truck hydraulic lifting radial plunger pump of the present invention is that pulse is less, stability is higher and has higher speed, and, simple in construction, manufacturing cost is relatively low.
Accompanying drawing explanation
Accompanying drawing 1 is the embodiment front view that cab of heavy truck hydraulic lifting radial plunger pump of the present invention has five groups of plunger unit；
Accompanying drawing 2 is the embodiment top view that cab of heavy truck hydraulic lifting radial plunger pump of the present invention has five groups of plunger unit.
With specific embodiment, cab of heavy truck hydraulic lifting radial plunger pump of the present invention is further described below in conjunction with the accompanying drawings.
Detailed description of the invention
Accompanying drawing 1 is the embodiment front view that cab of heavy truck hydraulic lifting radial plunger pump of the present invention has five groups of plunger unit, accompanying drawing 2 is the embodiment top view that cab of heavy truck hydraulic lifting radial plunger pump of the present invention has five groups of plunger unit, in figure, 1 is the pump housing, and 2 is stator, 3 is rotor, 4 is oil distribution casing, and 5 is plunger, and 6 is spring, 7 is reversal valve, and 8 is external pipeline.As seen from the figure, cab of heavy truck hydraulic lifting radial plunger pump of the present invention includes the pump housing 1, stator 2, rotor 3, oil distribution casing 4 and reversal valve 7；It is uniformly arranged in the radial direction with plunger unit at rotor 3；Stator 2 and rotor 3 eccentric setting；Oil distribution casing 4 is arranged on rotor 3 center, is provided with oil inlet passage and oil discharge passage and connects external pipeline respectively；Described reversal valve 7 is arranged on external pipeline, can switch over the turnover oil pipe line of cab hoisting cylinder；Described plunger unit includes plunger 5 and spring 6, and spring 6 is arranged between the bottom outlet of plunger 5 and plunger hole root step.The basic functional principle of cab of heavy truck hydraulic lifting radial plunger pump of the present invention is: as a example by a certain group in the five groups of plunger unit being arranged on rotor radial, this plunger unit of drive is rotated together with when rotating by rotor, plunger pushes against stator inner wall under the effect of spring force and centrifugal force, owing to stator and rotor have eccentric throw, during this plunger pile warp upper half protruding, the volume making plunger base space is gradually increased and forms negative pressure, and the space of this plunger base just can be from oil distribution casing oil inlet passage oil suction；When plunger turns to lower half, plunger is pushed inward by stator inner wall, and the volume in this plunger base space gradually decreases, and being stored in this plunger base space oil will flow out from oil distribution casing oil discharge passage, and have certain pressure.Rotor often rotates a circle, and the plunger unit being arranged on rotor radial all will complete an oil suction and fuel-displaced process.And for the lifting of driver's cabin with put down, then by the reversal valve being arranged on external pipeline, the turnover oil pipe line of cab hoisting cylinder can be switched over, thus realize the raising and lowering of hydraulic cab load lifting cylinder.Obviously, allowing with manufacturing cost as long as space can accommodate, the quantity of the plunger unit being arranged on rotor radial is the most, then efficiency is the highest, it is the most steady to run.Therefore, the plunger unit quantity of cab of heavy truck hydraulic lifting radial plunger pump of the present invention is more than three groups.Operation for convenience, it is achieved manual and electric dual-purpose, the rotor of cab of heavy truck hydraulic lifting radial plunger pump of the present invention is connected by gear or belt pulley rocking-turn handle, or connection has motor rotary shaft.
Obviously, the Advantageous Effects of cab of heavy truck hydraulic lifting radial plunger pump of the present invention is that pulse is less, stability is higher and has higher speed, and, simple in construction, manufacturing cost is relatively low.
