The present invention relates to a kind of ground-cutting device, have: mobile device; By the cutting engine of mobile device delivery, described cutting engine is used for cutting tool is rotated driving, and propulsion plant, and described propulsion plant is to move cutting tool the relative fltting speed in ground.
Background technology
Very early be used as the ground machine for sawing, to peel off this class ground-cutting device of cutting machine or slab cutter known and be used for flexible pavement or concrete surface are cut.
Accompanying drawing shows this known ground-cutting device, will explain detailedly below this.
Small-sized ground-cutting device is advanced with hand by the operator, and large-scale equipment configuration is useful on the mechanical equivalent of light feeding device that self drives simultaneously.Adopt machinery, hydraulic pressure or electric means that a wheel or a plurality of wheel are driven mostly for this reason.To the adjusting of fltting speed is by operating personnel manual control stepless or that have an executing agency of discrete velocity stage to be realized.In order to realize best work effect, fltting speed must be best, and described fltting speed depends on all multifactor.The rotating speed of the cutting axis of the efficient of the material composition of material to be cut, cutting tool (chopping disk) and life-span, depth of cut, driving chopping disk and the stability of torque and cutter sweep and track reliability all belong to main factor.
Because therefore these factors even also adjust favourable fltting speed not too easily and manually maintenance veteran operating personnel.Particularly may not recognize or only can recognize indirectly the Several Parameters operating personnel in the described parameter.For example operating personnel mostly only can be by judging the rotating speed of cutting axis to the noise that cuts shaft-driven cutting engine generation.When operating personnel have the earplug of regulation or other noise source is arranged, realize that this point is very difficult near the working site.Operating personnel can not get the answer signal of valuable relevant propulsive force when mechanically-propelled in addition, and operating personnel can directly feel the power on the handle of being added in.
If fltting speed is not adjusted to optimum state, various shortcomings will occur: chopping disk weak point in application life, chopping disk risk of breakage increase, the operating point of cutting engine is uneconomical or be unfavorable for environmental protection, cutter sweep or cutting engine g-load, increase working time and low work quality (for example depth of cut is inhomogeneous).
Summary of the invention
So the objective of the invention is to propose a kind of ground-cutting device, utilize described cutter sweep can guarantee best fltting speed all the time.
The implementation of the object of the invention is: ground-cutting device has mobile device, by the cutting engine of mobile device delivery, described cutting engine is used for cutting tool is rotated driving, and propulsion plant, described propulsion plant is to move cutting tool the relative fltting speed in ground, wherein have speed detector, described speed detector is used for the rotating speed of cutting tool or cutting engine is detected.Therefore speed detector also can be to detecting with the proportional parameter of rotating speed and having convincingness equally; With with the adjusting device of speed detector coupling, described adjusting device is used for actual value and predetermined rated value are compared and according to the deviation change fltting speed of actual value and rated value.
Actual value is transmitted to adjusting device, and with predetermined, the rated value of storage compares described adjusting device when for example installing in factory with actual value.Comparison adjusting device according to actual value and rated value is exerted one's influence to fltting speed.
Therefore can no longer manually pass ground-cutting device or manually adjust fltting speed, but automatically realize adjusting by adjusting device by the operator.The rotating speed of cutting axis or cutting tool (chopping disk) or the main rotating speed that drives motor (cutting engine) constitute the adjusting parameter in regulating loop of the present invention.
When the variation owing to external parameter (interference parameter), when fltting speed was too fast or slow excessively, the rotating speed of cutting axis will reduce or increase usually.The corresponding rotating speeds variation is detected by speed detector and is calculated in adjusting device.Then adjusting device can reduce or improve fltting speed, reaches predetermined rated speed again until cutting axis.
Cutting engine is an internal combustion engine in a preferred implementation of the present invention, the firing stroke of internal combustion engine, and therefore promptly Dian Huo the time interval is as engine speed and as the standard of the rotating speed of cutting axis and cutting tool.Speed detector is obtained the actual value of rotating speed according to firing stroke, and described actual value is transmitted to adjusting device.
Cutting engine is a motor in another useful embodiment of the present invention.Real-time power consumption is preferably as the standard of the rotating speed of cutting engine.
Can fix adjustment to rated value predetermined in adjusting device by producer.Also can be in another embodiment of the present invention according to running parameter, i.e. the variation of the nominal speed of the efficient of the material of material to be cut, cutting tool, depth of cut or cutting engine changes rated value by operating personnel.
Adjusting device is additional to propelling motor cutting engine, that belong to propulsion plant to one and controls, and described propelling motor relatively moves corresponding to ground to mobile device.
Also adjusting device optionally can be switched on or switched off, thereby make operating personnel can manually pass ground-cutting device all the time or manually fltting speed is fixedly adjusted to required value.
The automatic adjustment of fltting speed the risk of maloperation, the risk of especially unskilled operating personnel's maloperation have been reduced.Can save necessary so far manual operational unit in addition.Owing to adopted automatic adjusting, thereby guaranteed the economy and the work that helps environmental protection of ground-cutting device.
Description of drawings
Below comparative examples further is illustrated these and other advantage and feature of the present invention in conjunction with the accompanying drawings.
Unique accompanying drawing illustrates the concrete cutting device as ground-cutting device.
The specific embodiment
The main motor that drives as cutting engine 2 is fixed on the mobile device 1.Cutting engine 2 is fast burn engines, and this motor obtains fuel by oil cylinder 3.Cutting engine 2 drives chopping disk 4 as cutting tool by a not shown cutting axis, and described chopping disk is in known manner to there being ground to be cut to carry out sawing.Described chopping disk 4 can be the spark cutting blade.In the back of oil cylinder 3 water system 5 is set, utilizes this water system to supply water cutting blade is cooled off.
Be provided with a rear axle in the rear end of mobile device 1, can only see a trailing wheel in the drawings with two trailing wheels 6.Front end at mobile device 1 is provided with a front axle 7 with two front-wheels 8 equally.
The method that just adopts concrete cutting machine that ground is cut has two kinds of schemes substantially:
Operating personnel utilize 9 pairs of slab cutters of handle to pass on the ground on the one hand.Operating personnel can change fltting speed arbitrarily, and wherein operating personnel especially will consider (when offsetting cutting to the coefficient of the resistance of chopping disk) effectively propulsive force and according to the engine speed of perception of sound.
Another program is the scheme according to the known mechanically-propelled of prior art, and operating personnel connect described mechanical equivalent of light feeding device by operating parts 10.The motor that belongs to described propulsion plant drives trailing wheel 6, and wherein the fltting speed of therefore realizing is constant substantially in the known slab cutter according to prior art.
And being provided with a speed detector and an adjusting device according to the present invention, described device can be realized automatic adjustment and the change to fltting speed.Adjusting device calculates to the rotating speed of the cutting axis of adjusting standard as fltting speed or with the proportional parameter of this rotating speed.So other parameter, for example the rotating speed of chopping disk 4 or engine speed also are suitable for.
In internal combustion engine, for example can determine engine speed by obtaining firing stroke.The generation of pilot spark provides a signal of telecommunication, and speed detector calculates the signal of telecommunication in simple mode and the described signal of telecommunication constitutes the safe criterion of engine speed.
When the cutting engine that has when slab cutter in other embodiment of the present invention was motor, for example the evaluation of power consumption can be used as the standard of calculation engine rotating speed.
The scheme that rotating speed is calculated in certain any known being used to also is applicable to obtains necessary actual value.
The rated value that must keep when in adjusting device, having stored ground-cutting device work before dispatching from the factory.Common petrolic rated speed is 3.600 minutes
-1Thereby operating point best under load condition was at 3.400 to 3.500 minutes
-1Between.So for example can be predefined for 3.450 minutes to the rated value of rotating speed
-1In order to realize best work effect, motor must be always with oepration at full load.Though can adjust, be not indispensable to the rotating speed of motor.
When actual fltting speed was excessive, the power that acts on the chopping disk 4 reduced the rotating speed of chopping disk 4, and the rotating speed of cutting engine device 2 is reduced.When the actual value of rotating speed is lower than predetermined rated value, adjusting device will judge that then adjusting device controls and decrease the fltting speed that is produced by trailing wheel 6 to the propelling motor that belongs to propulsion plant to this point.Thereby the cutting force that acts on the chopping disk 4 diminishes, and the rotating speed of chopping disk 4 is restored and reaches the rated speed scope again.
But when the power that acts on chopping disk was too small, then the rotating speed of cutting engine was too high, thereby made rotating speed approach idle speed, in any case and this speed surpassed rated speed.Then adjusting device improves fltting speed, and this raising that causes cutting force of naming a person for a particular job also reduces skidding of chopping disk 4 thereupon.
Can all the time slab cutter be remained on the best operating point by adjusting device, can avoid the g-load of chopping disk 4 and cutting engine 2 on the one hand, can realize on the other hand working effectively smoothly.
Can be switched on or switched off propulsion plant in known manner, to avoid the accidental activation of ground-cutting device.
And can disconnect adjusting device, so that operating personnel can manually implement to advance or import the constant of the constant fltting speed of being held of not being subjected to that the practical function load influences as prior art.
