Description
Technical field
The present invention relates to a kind of equipment for the treatment of earth's surface.
Background technology
For the treatment of this motor-driven construction machinery on surface as known to from EP1408158B1.
Wherein described pavement milling machine comprises frame, and it has for actuation movement device and for driving the CD-ROM drive motor of equipment.This telecontrol equipment can comprise the wheel or the guidance set that are connected with frame by lifting column.
As roll-type driver, drive unit particularly will drive the milling and planing drum for milling earth's surface, preferably turns round in the mode of reverse turn operation.Milling and planing drum can be thrown off by a coupling device from drive system.On direct of travel, after milling and planing drum, in adjustable for height mode, one scraper is set, wherein scraper slips over by the earth's surface of milling and planing drum milling or by by the earth's surface of milling and planing drum milling.In milling operating process, the bottom margin of scraper is the k level place of the cutting circumference in milling and planing drum always.
According to the width of milling and planing drum, this construction machinery is with a kind of ribbon-like manner work.That is to say, after the earth's surface of predetermined portions is completed to milling, described construction machinery need to return to the area adjacent with milling.This reverse movement is called control run.In control run, equipment is in so-called actuated position, and equipment in impulse stroke in so-called operating position.
Here associated, contrary with impulse stroke, described milling and planing drum has the rotation direction identical with telecontrol equipment in control run.This is also referred to as synchronous operation.
In the time of synchronous operation for the instrument and the earth's surface that prevent milling and planing drum produce any accident collision, according to the description of state of the art, be necessary to make milling and planing drum to keep motionless in oppositely mobile process, this is because the in the situation that of milling and planing drum and ground unintentional engagement, and this construction machinery can a kind of uncontrollable and unexpected mode be accelerated.Because the peripheral speed of the milling and planing drum especially peripheral speed under service speed can be the doubly a lot of of machine travel speed, for example three times, therefore, in the situation that milling and planing drum engages suddenly, may cause strong and uncontrollable acceleration of this pavement construction machinery.And, with earth's surface unintentional engagement in the situation that, exist the milling and planing drum can impaired danger.
According to aforesaid EP1408158B1, milling and planing drum is thrown off with drive system after the strap end portion place, earth's surface processing moves from milling.In control run, this construction machinery can, without any the beginning that moves backward to part to be processed in hidden danger ground, in this beginning, first need motor to be suppressed at idling speed to carry out the coupling again of milling and planing drum now.By the CD-ROM drive motor reduction of speed being made up of internal combustion engine, to idling speed and it is accelerated to service speed again both need more one period of quite long stand-by period, these are different from common passenger car motor.
Before starting to process next ground watchband, need to make CD-ROM drive motor again in service speed.These processes are extremely consuming time and very heavy concerning vehicle operation person, especially in the situation that more processing shorted segment.And the loads change frequently of the continuous joint of clutch and the motor causing can cause the wearing and tearing of coupling device, motor and other all components related in drive system to increase.
A kind of motor-driven construction machinery of developing in order to eliminate these shortcomings and a kind of method of processing earth's surface are known from DE10 2,006 024 123A1.
Pavement milling machine described in this patent provides: milling and planing drum can be removed from milling by the lifting of rotation or the lifting column by telecontrol equipment.The milling and planing drum promoting and the distance on earth's surface are by a supervising device monitoring.If this supervising device monitors a difference in preset distance, be raised milling and planing drum and the motor that are now still rotated further are thrown off, or by telecontrol equipment and motor disengagement, described frame is raised or generates a caution signal.If milling and planing drum really contacts with ground, it only needs to destroy current rotational.The quality of this construction machinery is enough greatly to stop construction machinery beating on direct of travel.
In such construction machinery, milling and planing drum can for good and all keep connecting with motor, particularly in synchronous control run.In the time carrying out necessary adjustment, for example, by suppressing and add speed motor, can be reduced to a quite reasonably scope loss of time.
But such supervising device can not carry out reliable, flawless monitoring to the monitoring of the distance that promotes milling and planing drum and earth's surface in rotating provides any assurance.In the time that the security reaction of supervising device does not occur or only occur too late, there is risk, for example, the in the situation that of Shang You crack, earth's surface or earth's surface fluctuating suddenly.This can produce serious consequence, because the milling and planing drum in rotating may ground-engaging and unexpected and uncontrollable mode makes construction machinery acceleration with one.
Therefore, the object of this invention is to provide a kind of equipment of processing earth's surface, use this equipment, can make the processing procedure on earth's surface become reliably, effectively, especially between impulse stroke and control run, change required time shorten, and shorten corresponding waiting period.
Summary of the invention
This target especially can realize by a kind of equipment of processing earth's surface, this equipment comprises telecontrol equipment, equipment (especially earth's surface being carried out the milling equipment of milling) and for driving the drive unit of described telecontrol equipment and equipment, described equipment is movable to operating position and actuated position, in described operating position, equipment engages with ground table handling, and in actuated position, equipment does not operate and engages with earth's surface, in this equipment, provide sensor device, the described actuated position of its monitoring device and/or at least one running parameter of equipment, it is the power consumption of equipment, operating rate, velocity of rotation or its gradient, and/or at least one parameters of loading of monitoring moving device.This equipment also includes control device, in actuated position and/or in the case of monitoring the parameter value of at least one monitored running parameter or parameters of loading and setting deviates, the driving power that it reduces the frictional connection between drive unit and equipment and/or is transferred to equipment by drive unit.

The specific embodiment
Comprise frame 3 and drive unit 6 for the treatment of equipment or the construction machinery 1 on earth's surface as shown in Figure 1.This drive unit 6 is for actuation movement device 2 and equipment 4, and in this example, equipment is milling equipment.Telecontrol equipment 2 is made up of wheel in the present embodiment.Milling equipment 4 can separate with drive unit 6 by coupling device (not shown), and can enter raised position (not shown) by the lifting gear 5 in frame 3.
The position of the reduction herein illustrating corresponding to operating position or to shown in earth's surface 13 impulse stroke of carrying out milling.As shown in the figure, in impulse stroke, the direction of rotation of the direction of motion of the rotation direction of equipment 4 and equipment 1 or wheel 2.At raised position or actuated position (not shown), equipment 4 no longer engages with the earth's surface 13 of wanting milling.In this position, equipment " backward " moves to the starting point of a new milling band.In such transition period, the rotational motion of equipment 4 is synchronizeed with the direction of motion of equipment 1.If equipment 4 and earth's surface 13 uncontrollable engages or another obstacle occurs, equipment 1 accelerates with unexpected and uncontrollable mode.This " fault " should be avoided.
In control run, the driving power that is especially delivered to equipment 4 by reduction can be realized above-mentioned purpose.For realizing this object, the running parameter of equipment 1 and parameters of loading be by corresponding Sensor monitoring, by the basic parameter comparison of the parameter monitoring and existing setting, starts the corresponding protection of eliminating above-mentioned " fault " retouch and execute by suitable control device.The invention provides a kind of sensor device, its band is useful on the different sensors that at least one running parameter of monitoring or parameters of loading and setup parameter value deviate.For this content, equipment 1 is mainly equipped with the combination of sensor independently or these sensors.Therefore, comprise at least one load sensor 8, at least one live load sensor 10 and at least one inclination sensor 12 according to the equipment 1 of Fig. 1, the function of these sensors will describe below in more detail.
Like this application class, be applied to inclination sensor, this inclination sensor monitoring is due to the inclination of the equipment that similarly situation causes.Equally, in this case, the frictional connection between drive unit 6 and equipment 4 and/or provided or the effective power of the supply equipment 4 that produces reduces by corresponding control signal by drive unit 6.
On the other hand, live load sensor 10 is monitored following parameter: operating rate and/or the speed of power consumption, equipment provided here or milling equipment 4, or their variation.Once monitor unexpected especially lifting, produce corresponding control signal, and reduce frictional connection between drive unit 6 and equipment 4 and/or provided or the effective power of the supply equipment 4 that produces by drive unit 6.
Fig. 2 schematically shows the second embodiment of equipment 1, and has shown especially the driving diagram of this equipment.For the conversion time that minimizing equipment 1 changes between control run and impulse stroke, in the time monitoring by sensor 8,10, drive unit 6 is not thrown off with equipment 4.The infringement that the uncontrollable acceleration of equipment 1 brings when being reduced in the unintentional engagement on equipment 4 and earth's surface, drive unit 6 includes main drive 15 and assistant drive device 18.Main drive and assistant drive device 15,18 both can be energized or remove excitation by the independently coupling device of equipment 4 16,19, are wherein that impulse stroke or control run are carried out to the control of coupling device 16,19 according to stroke on the horizon.
In control run, equipment 4 is coupled by coupling device 19 and assistant drive device 18, and in impulse stroke, and equipment 4 is realized and being connected of main drive 15 by coupling device 16.Under couple state, the operation power that assistant drive device 18 provides for equipment 4 is less than the operation power that main drive 15 provides for equipment 4.Therefore the equipment 4 that can guarantee this equipment keeps continuous especially rotating speed in control run, thereby can again reach rapidly mode of operation in the time that new impulse stroke starts.In order to prevent equipment 1 uncontrollable acceleration or be damaged in control run, the driving power being provided by assistant drive device 18 arranges like this, guarantees equipment 4 in " lost motion operation " but can not be in impulse stroke.In similar embodiment, also may in control run, reduce the velocity of rotation of equipment 4, or even this velocity of rotation is reduced to zero and within the short time again switching to before the impulse stroke may be being again coupled with main drive 15, accelerate to operating rate or close speed.For this content, making the operating rate of equipment 4 synchronize with the actuating speed of main drive 15 by assistant drive device 18 is possible, especially in control run.
Fig. 3 shows the schematic diagram of the 3rd embodiment of equipment 1, has especially shown the coupling diagram of this equipment.
For improved malfunction monitoring, the performance realizing for disconnecting the coupling device 16 that is connected 17 (schematically illustrated) herein between drive unit 6 and milling equipment or equipment 4 is transformable.In the situation of the coupling device 16 of the hydraulic actuation illustrating herein, in figure, as shown in Reference numeral 9, the restriction of the driving power that the moment of torsion transmitting that the change of coupling pressure causes maybe can transmit will occur.Can adjust individually this pressure for this construction machinery by 11 of adjusting devices.The power transmitting of the coupling device 16 of this hydraulic actuation can be set as a quantity ideally, and this coupling device especially can not be skidded and therefore can not produce coupling device 16 any increase wearing and tearing and tear.Accompanying drawing shown here also shows frictional connection or the coupling of the coupling device 16 in equipment 1 and slides and can regulate by control device.Like this, in the situation that equipment 4 contacts with earth's surface 13 is unexpected, equipment 4 can further be driven in control run, also can guarantee that drive unit 6 can not make equipment 1 accelerate because frictional connection reduces simultaneously.
