Abstract
Self-operating road pavers comprise an internal combustion engine (23) that drives a hydraulic pump for operating hydraulic motors that act as drives (24 - 28) for the chassis and other components of the self-operating street paver. At least some drives (24 - 28), in particular the transportation drive of the street paver, must also operate at the same speed under varying conditions. In order to guarantee this, in known street pavers the internal combustion engine (23) is operated at a relatively high speed. Under normal conditions, this speed is too high, so under such conditions the profitability of known street pavers suffers. The object of the invention is to operate the internal combustion engine (23) of the street paver at a variable speed that is regulated such that the drives (24, 25, 28) that require a constant speed remain substantially constant even if changing loads, and consequent changing speed of the internal combustion engine (23) occur. This allows the internal combustion engine (23) to always be operated in an optimum speed range.
Description
Technical field
The present invention relates to a kind of by method claim 1 preamble, that be used to move the sub-base grader of walking certainly.
Background technology
Sub-base grader from walking not only has travel driving unit, and has a plurality of other drive units.Especially at least one screed (Einbaubohle) that hangs over the sub-base grader back has and is used for the drive unit that at least one makes bar and/or at least one vibrator firm by ramming.Other drive unit is provided for being delivered to the conveyer of screed by the material of sub-base grader making and being used to drive the cloth screw rod with described material cross direction profiles.These drive units are hydraulically worked usually.But they also can be fully or partly electricity consumption work.Therefore the internal combustion engine produce power of sub-base grader is in order to operation drive unit hydraulic pressure and/or electric power.Usually at least one hydraulic pump of internal combustion engine drive, it is supplied with to the hydraulic motor that matches with travel driving unit and other drive unit.
For surfacing, at first the travel driving unit of sub-base grader, be used to make firm by ramming bar and/or vibrator drive unit with constant rotating speed or frequency operation, therefore the road surface that is produced by sub-base grader does not change.For this reason, the internal combustion engine in known sub-base grader is with constant rotating speed operation.The preliminary election when paving process begins of this rotating speed, and make the energy that produces by internal combustion engine all be enough in all cases to the enough energy of all drive unit supplies of sub-base grader.During the road curve that especially alternately changes, need energy more or less sometimes in uphill way and descending highway section.Therefore must so select the rotating speed of the prior foundation of internal combustion engine, make internal combustion engine in uphill way, produce enough energy, in other highway section especially descending highway section, provide too much energy.So sub-base grader is so operation in this known method, make internal combustion engine produce too much energy far away.
Summary of the invention
Present task of the present invention is, realizes a kind of method, therefore can move the sub-base grader from walking economically.
Be used to solve the measure that the method for above-mentioned task has claim 1.Therefore set, the rotating speed and the load of internal combustion engine change relatively, and make the approximate at least maintenance of at least one drive unit of sub-base grader constant at this.Therefore the present invention is that with so far the different of the method for operation it is constant that the rotating speed of internal combustion engine does not keep, but change relatively with load.Therefore possible is, operation of combustion engine like this, and it is instantaneous for the required energy of operation sub-base grader to make internal combustion engine always only be created in.Therefore sub-base grader can move economically.The change relevant with load of internal-combustion engine rotational speed may cause the change of the rotating speed of each drive unit.Therefore set in addition by the present invention, it is constant that at least one drive unit keeps aspect its rotating speed or frequency.Therefore although internal-combustion engine rotational speed changes, these are held constant to the characteristic on the road surface that will be produced and the drive unit that quality has appreciable impact, and the rotating speed or the frequency that always provide for drive unit keep constant required energy.
Enough within the scope of the invention is, the rotating speed or the frequency that will be held constant drive unit thus only keep constant basically.The rotating speed of therefore relevant drive unit or frequency can depart from rated speed or rated frequency by tolerance decision ground, and are not only to depart from up but also down.Will be held the rotating speed of constant drive unit or frequency thus therefore always remain on one and comprise rated speed or rated frequency in interior narrow range.Will to be held in the constant drive unit can be different to this scope different, and this is the purpose used according to relevant drive unit.Rotating speed or frequency are held the constant range of speeds or frequency range and can fluctuate below 5% with respect to rated speed or rated frequency.
Usually the frequency of the vibrator of the frequency of making bar firm by ramming of the rotating speed of the travel driving unit of sub-base grader and/or screed and/or screed is held constant.The rotating speed or the frequency of preferred all three drive units of enumerating all are held constant.On the contrary, other drive unit, for example be used for carrying the drive unit of conveyer of ground surface material and the drive unit that is used for carrying the cloth screw rod of described material transverse to sub-base grader along sub-base grader, needn't keep constant, the rotating speed of these drive units can change along with the change of internal-combustion engine rotational speed.Because especially for the not influence of road surface of making, institute becomes unnecessary so that these drive units keep constant to these drive units of enumerating aspect rotating speed.
A kind of preferred implementing form according to method is set, and internal combustion engine makes internal combustion engine satisfy the energy requirement of all drive units of working simultaneously with such rotating speed operation.Therefore these drive units than the macro-energy demand time internal combustion engine can move with high rotational speed, this moment, internal combustion engine produced more energy, especially produced for hydraulic pump or the enough energy of generator by internal combustion engine operation.On the contrary, if the energy requirement of these drive units is less, then can reduce the rotating speed of internal combustion engine.Internal combustion engine can move in its rotating speed for all loading condition optimizations.This causes the energy-conservation or energy-optimised operation of internal combustion engine.
According to another favourable form of implementation of the inventive method, when each rotating speed of internal combustion engine, can carry and make the rotating speed of these drive units or frequency keep constant required energy will being held constant drive unit aspect rotating speed or the frequency to one or each.If therefore a drive unit is carried required higher-energy to this drive unit so, and is that promptly the rotating speed of this drive unit or frequency keep identical basically on such degree owing to the making condition that changes needs more multipotency.If this more multipotency can not be produced by the instantaneous rotating speed of internal combustion engine by internal combustion engine, for example, then correspondingly improve the rotating speed of internal combustion engine because other drive unit also needs more multipotency, therefore sufficient energy is provided again generally.Internal combustion engine can move with such rotating speed with load under all running statuses of sub-base grader relatively, and this rotating speed is enough to produce by these drive units, the especially required energy of all drive units.
In a kind of preferred implementing form of the inventive method, carry out the adjusting of the rotating speed of internal combustion engine, make that the rotating speed of internal combustion engine is so infinitely being improved or reducing on the degree, promptly internal combustion engine produces by the required energy of all drive units.Therefore internal combustion engine can always move with the operational factor of optimizing, and especially aspect consumption, optimize.
Method of the present invention is set in addition, when the energy requirement of the tamper of the travel driving unit of sub-base grader, screed and/or vibrating device improves, by corresponding adjusting, improve the rotating speed of internal combustion engine on degree like this, promptly the frequency of the vibrator of the speed of travel of sub-base grader and screed and tamper is approximate at least keeps constant.Equally when energy requirement descends, the reduction of being regulated of the energy by being delivered to relevant drive unit makes the rotating speed of these relevant drive units or frequencies keep constant.The influence of all changes is considered in this adjusting continuously, and the maintenance same rotational speed enduringly or the frequency of the drive unit that therefore guarantees to be held constant.
Preferably set, set one or more regulating loops as the internal combustion engine of power generator with as user's the constant drive unit that will be held, so the rotating speed of these drive units or frequency is especially also always approximate at least when load alternately changes keeps constant.Therefore when drive unit is supplied with when the load of sub-base grader changes the rotating speed of the internal combustion engine of the energy hunting of generation by correspondingly changing sub-base grader compensated.
According to another form of implementation of method, each rotating speed that needn't will be held constant drive unit aspect rotating speed and frequency all changes when changing follows the tracks of the rotating speed of regulating internal combustion engine.In the time will being held the little rotating speed deviation of constant drive unit thus, the rotating speed deviation was surpassed slightly or when being lower than the rotating speed amplitude that allows by tolerance decision ground, at first regulate rotating speed, make rotating speed equal rated speed or within the range of speeds that allows, wherein additional energy needn't be flowed to the drive unit that will be held constant by constant drive unit from rotating speed or frequency.On the contrary, if need less energy will being held constant drive unit aspect rotating speed or the frequency, so unnecessary energy is from being delivered to and needn't keeping constant drive unit aspect rotating speed or the frequency will being held constant drive unit aspect rotating speed or the frequency.In the time of aspect rotating speed or frequency, will being held the little load variations of constant drive unit, to being held constant drive unit aspect rotating speed and/or the frequency and needn't keeping aspect rotating speed or the frequency carrying out between the constant drive unit producing and the compensation of the energy that provides by internal combustion engine.

Explain the preferred embodiments of the present invention in detail by accompanying drawing below.
Fig. 1 shows the lateral view of sub-base grader;
Fig. 2 shows the block diagram that is used to regulate the sub-base grader operation.
The specific embodiment
The sub-base grader 10 that is used to produce road surface, preferred flexible pavement is described in signal in Fig. 1.
Sub-base grader 10 has walking mechanism 11, and this walking mechanism constitutes crawler type walking mechanism in the embodiment shown.But the walking mechanism 11 of sub-base grader 10 also can be a wheel type traveling mechanism.Sub-base grader 10 constitutes walking certainly.For this reason, walking mechanism 11 is driven by driver element 12, makes sub-base grader 10 to advance on the direction 13 that paves.
On the direction 13 that paves, see, the pond shape tank 14 of flute profile formation in other words was set before driver element 12.Tank 14 is used to admit deposit body, the especially asphalt mixture of the material that is used to produce the road surface.Conveyer 35, especially drag conveyor by not showing in Fig. 1 are delivered to the back side of sub-base grader 10 from tank 14 against the direction 13 that paves with material, and are before cloth screw rod 15.Cloth screw rod 15 is arranged on driver element 12 back.Cloth screw rod 15 reverse 13 extends transverse to paving, and is used for material is evenly distributed on the whole working width of sub-base grader 10.
On the direction that paves, screed 16 is set in cloth screw rod 15 back.Screed 16 can hang on the support arm 17 with moving up and down.Support arm 17 is bearing on the walking mechanism 11 of sub-base grader 10 pivotly.Screed 16 can be the screed 16 (showing in Fig. 1) of one, and it can not change on width; But it can be the screed of multi-piece type also, comprises the movable plate of a mainboard and side direction, therefore can change the width of screed.
Screed 16 has board substrate 18 and is arranged on base plate 19 below the board substrate.Screed 16 will be by on the material of making by being placed on the bottom surface of its base plate 19.Screed 16 has the tamper of seeing before being arranged on board substrate 18 20 in addition on the direction 13 that paves.Tamper 20 have one or more transverse to pave reverse 13 on the whole width of screed 16, extend make bar 21 firm by ramming.Making bar 21 firm by ramming can vertically move up and down before the base plate 19 of screed 16.For this reason, tamper 20 is provided with corresponding driving device 24, is used to cause reciprocal the moving up and down of making bar 21 firm by ramming.
Especially the base plate 19 of screed 16 can vibrate by the vibrating device 22 that at least one has at least one vibrator, preferred a plurality of vibrators, will be by the material pre-compacted on the road surface of making so that will be used to constitute.In order especially to cause the oscillating movement of base plate 19, vibrating device 22 has the drive unit 25 that for example is used for one or more uneven drivers.
The driver element 12 of sub-base grader 10 has an internal combustion engine 23 that does not show in Fig. 1.At this diesel engine preferably.But driver element 12 also can have other motor, also can have a plurality of motors in case of necessity.Driver element 12 has at least one hydraulic pump that is driven by internal combustion engine 23 in addition.Therefore drive unit 24～28, the especially hydraulic motor of hydraulic pressure are supplied to essential energy, and are to be supplied to the hydraulic oil that is under the pressure.Can consider that also internal combustion engine 23 additionally or drives at least one generator with replacing, its generation is used for the electric current of the drive unit of electric power, especially motor.Mode at the sub-base grader 10 usefulness diesel oil-hydraulic pressure of this demonstration is moved.Therefore internal combustion engine 23 only drives a hydraulic pump, perhaps also drives a plurality of hydraulic pumps in case of necessity.This at least one hydraulic pump is supplied with the hydraulic oil that is under the pressure to the drive unit 24～28 that all of sub-base grader 10 constitute hydraulic motor.
Shown in sub-base grader 10 in, the drive unit 24～28 of hydraulic pressure is that hydraulic motor is used for walking mechanism 11, conveyer 35, cloth screw rod 15, makes bar 21 and vibrating device 22 firm by ramming.The hydraulic motor that is used to drive walking mechanism 11 is the travel driving unit of sub-base grader 10, being used to make firm by ramming the hydraulic motor that bar 21 moves up and down and being used to drive the hydraulic motor of the uneven driver of vibrating device 22 must be with constant rotating speed or narrow range of speeds operation, and under all service conditions that can consider, be not always the case, that is to say when every kind of load and all load variations and be not always the case, therefore sub-base grader 10 can produce (making) road surface continuously, and the road surface has substantially the same quality on whole making length.For this reason, precondition is that the material on identical in all cases making speed and new road surface is by the tamper 20 of screed 16 and the constant compacting of vibrating device 22.
In the route change of the roadbed that will be applied in the road surface for example in uphill way or the descending highway section, because variation in the different materials storage level of cloth screw rod 15 fronts, and because will be by the temperature fluctuation of the material of making, the drive unit 24,25 and 28 of making bar 21 and vibrating device 22 firm by ramming that is used for walking mechanism 11, screed 16 needs the different energy of time per unit, it is the different volume flow of hydraulic oil, its oil pressure is preferably constant, keeps constant basically for use in walking mechanism 11, the drive unit 24,25 of making bar 21 and vibrating device 22 firm by ramming and 28 rotating speed.If actual speed and rated speed only depart from predetermined boundary, promptly in the desired speed amplitude preferably ± 2.5% of rated speed, these rotating speeds are substantial constant so.
For under all service conditions of sub-base grader 10, provide enough energy or with the as many energy of demand, can keep constant for use in walking mechanism 11, the drive unit 24,25 of making bar 21 and vibrating device 22 firm by ramming and 28 rotating speed, the present invention sets, the rotating speed of internal combustion engine 35 changes according to the load of all drive units 24～28, makes the drive unit 24,25 and 28 be used for walking mechanism 11, make bar 21 and vibrating device 22 firm by ramming keep constant or be positioned at the predetermined range of speeds at least.
When the rotating speed 23 of internal combustion engine changes, thereby feed flow, the especially volume flow of time per unit hydraulic oil by the rotating speed of oil-engine driven hydraulic pump and hydraulic fluid change, and therefore corresponding driven rotating speed that is used to constitute the hydraulic motor of drive unit 24～28 changes.On the contrary, the pressure of hydraulic oil always keeps constant.
The present invention sets a kind of adjusting device, although the rotating speed of internal combustion engine 23 changes, this adjusting device makes the hydraulic motor rotating speed of certain drive unit 24,25,28 keep constant, although carry either large or small energy to relevant hydraulic motor, therefore corresponding hydraulic motor produces either large or small power in order to driving walking mechanism 11, to make bar 21 or vibrating device 22 firm by ramming according to the instantaneous service condition of sub-base grader 10, but its rotating speed does not change or not obvious change.The change of energy preferably realizes by the volume flow that changes hydraulic oil under the constant situation of the pressure of hydraulic oil.
In Fig. 2, show the adjusting of the main drive unit of sub-base grader 10 with the form of block diagram.Therefore internal combustion engine 23, the drive unit 24 that is used to make firm by ramming bar 21, the drive unit 25 that is used for vibrating device 22, the drive unit 26 that is used for conveyer 35, the drive unit 28 that is used for the drive unit 27 of cloth screw rod 15 and is used for the walking mechanism 11 of sub-base grader 10 are got in touch with adjusting device 29.The rotating speed as adjustable parameter of internal combustion engine 23 guides to drive unit 24～28 by holding wire 30.The measurement parameter of internal combustion engine 23 arrives adjusting device 29 by holding wire 31.Preferably the Motronic control maps device by internal combustion engine 23 also especially offers adjusting device 29 with the real-time torque of internal combustion engine.In addition, the measurement parameter of drive unit 24～28 arrives adjusting device 29 by holding wire 32.Pass through holding wire 33 to internal combustion engine 23 feed adjustment parameters from adjusting device 29.In addition, by adjusting device 29 adjustable parameter is guided in the drive unit 24～28 each by control line 34.
Fig. 2 shows, by adjusting device 29 only will be used to make firm by ramming the drive unit 24 of bar 21 rotating speed, be used for screed 16 drive unit 25 rotating speed and be used for that the rotating speed of drive unit 28 of walking mechanism 11 of sub-base grader 10 is approximate in certain range of speeds to keep constant.Cloth screw rod 15 and the variable rotating speed of conveyer 35 usefulness are driven, and especially the rotating speed of drive unit 26,27 is along with the change in rotational speed of internal combustion engine 23 changes linearly.
Change if be used to drive the walking mechanism 11 of sub-base grader 10, the vibrating device 22 of screed 16 and/or the power demand of making bar 21 firm by ramming of tamper 20, drive unit 26 and/or the raising of the drive unit 27 of cloth screw rod 15 or the energy of reduction of so little variation by being delivered to conveyer 35 compensates.
At the drive unit 28 that is used for walking mechanism 11, when being used to the bigger variation of energy requirement of the drive unit 25 of making the drive unit 24 of bar 21 firm by ramming and/or being used for cloth screw rod 15, these energy that only change by the drive unit 27 that improves or reduce the drive unit 26 that is delivered to conveyer 35 and/or cloth screw rod 15 no longer can be compensated, adjusting device 29 just changes the rotating speed of internal combustion engine 23, and wherein the rotating speed of internal combustion engine is enhanced or reduces.
In order to determine drive unit 24,25 and 28, the preferred power demand of also determining drive unit 26 and 27 at least, test constantly is made the frequency of bar 21, the frequency of vibrating device 22 and the making speed of sub-base grader 10 firm by ramming, perhaps test constantly drive unit 24,25 and 28 be hydraulic motor or motor with frequency or the proportional rotating speed of making speed.The power demand that improves can be released from the decline of frequency, rotating speed or making speed.On the contrary, less power demand can be determined by the rising of frequency, rotating speed or making speed.As long as frequency or the rotating speed measured leave predetermined scope, preferably in the rotating speed window of determining, then change the rotating speed of internal combustion engine 23 by adjusting device 29, make internal combustion engine produce energy more or less, so that compensation drive unit 24, the energy requirement of 25 and 28 change, make tamper 20 and vibrating device 22 frequency or be used for tamper 20 and the rotating speed of the drive unit 24 of vibrating device 22 and 25 and the rotating speed of drive unit 28 of walking mechanism 11 that is used for sub-base grader 10 once more corresponding to rated value predetermined value in other words, especially in predetermined scope, for example in the rotating speed window.Be implemented in the adjusting in the window, so that needn't and be used for the rotating speed of drive unit 28 of walking mechanism 11 or each only small variation of frequency is made a response to tamper 20, vibrating device 22.
