The specific embodiment
Compare with existing various concrete extruders, the concrete extruder of describing in each accompanying drawing is an improved machine, because it can more effectively be worked and can more effectively tackle the stuck problem that is difficult to expect, when the making concrete fin, still can produce the needed sufficient tamping power of tamped concrete mixture simultaneously.
This is by adopting a hydraulic system to reach, and hydraulic system comprises a fluid pressure drive device and a hydraulic cylinder, in order to drive beater.Vibrations and the stuck problem that is caused by the foreign matter that enters concrete mix can be born by this system.
As shown in fig. 1, concrete extruder 10 has front portion 11 that is limited by forebay 12 and the rear portion 13 that is limited by afer bay 14.Concrete mix hopper 16 be anterior 11 and rear portion 13 between and concrete mix can be directed to the lower end 17 of machine downwards, its place's mixture by beater 25 tampings on the road surface.
The concrete reaction force that whole extruder is smash 17 places, lower end of hopper 16 owing to beater 25 hammers moves forward.One wheel pairs 18 and two Height Adjustment oil cylinders 20 are installed in the front of forebay 12.Front end and each oil cylinder that oil cylinder 20 is mounted in frame are the mount pads of wheel.This allows the height with respect to wheel and ground adjustment forebay 12 and afer bay 14, so as to adjusting the height of the concrete fin that will be formed.
The turning-bar 21 that is connected in wheel is used for extruder is turned to.Turning-bar 21 is to be connected in one of two front-wheels, and another wheel is to be connected in turning-bar by an assembly, and this assembly comprises a tie rod arm and two spherojoint (not shown)s, and this makes two wheels to turn to turning-bar 21.The horizontal horizontal situation of level gauge (not shown) indication across the front portion installation of machine is so that keep the level of machine.The level of machine can be regulated with the Height Adjustment oil cylinder 20 of hydraulic pressure.Pointer (not shown) at a steel of the front of machine is used to follow the backguy path, so that machine is correctly advanced on direction of advance.
Power set and hydraulic pump 24, beater 25 and the concrete that pours into hopper 16 from concrete agitator-body truck (not shown) applied in front portion 11 (see figure 2)s that needed other parts of tamping power all are mounted in extruder 10.Rear portion 13 (see figure 3)s of machine have a long molding box 22, are formed the concrete fin of the interior shape with molding box 22 by molding box 22 by compacted concrete.Each wall that Fig. 3 also depicts hopper 16 remains in steady status by support column 23.
Fig. 1 and 2 depicts and is installed in each parts of anterior 11 li.Power set and hydraulic pump 24 are to be expressed as in the housing that is contained in the preceding upper end that is positioned at forebay 12.In this embodiment, power set are motors of one 12 horsepowers, are used to drive hydraulic pump.The hydraulic fluid of using in this system is a hydraulic oil.
Hydraulic oil flows out hydraulic pumps 24 and flows through fluid pressure line 29 from hydraulic pump outlet 28 and flows to oil content and join controll block 30.Controll block has the hydraulic efficiency slide valve (not shown) for 30 li, and it can be controlled and change the oil that flows through controll block 30 and flow.Two fluid pressure lines 45,46 can drive controll block 30 and one that fluid is communicated with between the oil cylinder 32 of beater 25. Fluid pressure line 45 and 46 is connected to front end (fluid pressure line 45) and rear end (fluid pressure line 46) of hydraulic cylinder 32 from controll block 30.In this embodiment, this hydraulic cylinder is a pilot cylinder, enters the front-end and back-end of oil cylinder by alternately making higher oil pressure, the cylinder bar of oil cylinder is stretched out and withdraws.
Because beater is to be connected in this hydraulic cylinder, it is reciprocating to the concrete mix in the hopper that the HYDRAULIC CONTROL SYSTEM that comprises hydraulic pump, controll block, pipeline and hydraulic cylinder beater.Hydraulic cylinder 32 is pilot hydraulic cylinder.A little pilot hole the when plunger in oil cylinder arrives its stroke terminal in the oil cylinder is opened, and fluid is flowed out by pilot hole under pressure and flows to guiding valve along fluid pressure line, and fluid orders about that spool moves and the direction that changes oil stream in guiding valve.This will push back beater to opposite direction, reciprocating so as to making beater.
Also can adopt other cylinder/spool valve combinations to drive beater, for example use pressure-sensitive guiding valve or electromagnet, but pilot cylinder/spool valve combinations is best, because it can avoid changing with the presser sensor guiding valve unreliability of desired pressure rising of the direction of motion and the electric device such as electromagnet.It may be dangerous that pressure raises.Pilot cylinder can be worked in simple and safe mode under unique hydraulic control, and does not need the relatively poor signal of telecommunication of reliability or switch.
As shown in Figure 2, hydraulic cylinder 32 is to be installed on a support pivotly, and this support is the inboard of being fixed in forebay 12.The movable cylinder bar 33 of hydraulic cylinder 32 is to be connected in beater 25 pivotly, and beater comprises beater oscillating deck 27, ram head 26 and is installed in beater header board 36 on the ram head 26.This hydraulic cylinder by its pivoted connection, can be adjusted its position with respect to frame 12 and beater 25, to adapt to the motion of beater.
The cylinder bar 33 of hydraulic cylinder 32 is connected in support 35 pivotly, and support 35 is to be welded on the oscillating deck 27.Ram head 26 and ram plate 36 all are fixedly mounted in oscillating deck 27 and can swing thereupon.Ram head 26 is to be connected on the rear end of oscillating deck 27.
Oscillating deck 27 is to be suspended to two groups of parallel arms 38, and each arm 38 is connected in oscillating deck 27 transverse member 40 of rigidity pivotly.Two transverse members 40 firmly are installed between two sidewalls of forebay 12, above oscillating deck 27.The upper end of parallel arm 38 is connected in transverse member 40 at pivotal point 42 with bearing pin, and their lower end is connected in oscillating deck 27 at pivotal point 43 with bearing pin.
Therefore, along with hydraulic cylinder stretches out under the fluid pressure from the variation of controll block 30 and withdraws, oscillating deck 27 is done little movement in a curve to and fro around pivotal point 42 and 43.The swing effect of oscillating deck 27 makes ram head and ram plate 36 repeatedly make hammer in the bottom of hopper 16 to concrete mix and smashes motion, thereby the concrete tamping is advanced in the molding box 20.
Fig. 4 A and 4C depict the schematic diagram of the wobbling action of beater 25.Fig. 4 A describes the retracted position of beater 25.Under the hydraulic pressure effect of the front portion that supplies to hydraulic cylinder 32 by preceding fluid pressure line 45, cylinder bar 33 is withdrawn in the oil cylinder 32 fully.The beater oscillating deck 27 that is suspended to pivotal point 42 is moved to the position shown in Fig. 4 A by oil cylinder 32, and this is to leave concrete position farthest.
Fig. 4 B depicts a centre position, and on this position, the cylinder bar of oil cylinder is in the halfway that stretches out, and the beater with momentum moves to the left side shown in Fig. 4 B.In this view, parallel arm 38 is in vertical.
Fig. 4 C depicts oil cylinder cylinder bar and stretches out the longest position, and in this point, ram plate (not showing among Fig. 4 A and the 4C) applies its maximum power to concrete mix.In this figure, supplying to the rear portion of oil cylinder 32 by back fluid pressure line 46 and be that the cylinder bar 33 of oil cylinder 32 stretches out fully under 33 behind the effects of higher hydraulic pressure at the cylinder bar.In Fig. 4 C, parallel arm 38 swung to one with the opposite angle of inclination shown in Fig. 4 A.Carrying out after hammer smashes, the commutation of oil pressure that oil cylinder is 32 li makes beater 25 return to the complete retracted position shown in Fig. 4 A from this position through the position shown in Fig. 4 B.
This have the pressure controlled double acting hydraulic cylinder in front-end and back-end and make beater send extraordinary tamping power with high speed operation and to concrete.When hydraulic cylinder 32 bore unexpected and/or too high power, the reducing valve on it discharged high pressure with regard to work, makes extruder exempt from damage, exactly, is the damage of avoiding being caused by back pressure beater, hydraulic cylinder and all other driver parts.In case meet with obstruction, the two-way effect of hydraulic cylinder oppositely stops beater with regard to making the oil pressure that acts on beater at once.Then, can get obstacles out of the way safely and work on again.
The advantage of the concrete extruder of hydraulic power is that hydraulic pressure beater parts are stopped immediately.And the stopped process of mechanokinetic extruder slowly many, generally be just can stop through mechanical part after several seconds.Can be in the extruder course of work operating personnel's erect-position place, one or several point on extruder is provided with emergency stop button.When touching emergency stop button, it will make beater stop at once, the sort of mechanical delay that does not exist existing extruder to experience.
Fluid in this hydraulic system flows and can be changed with reverse instantaneously.The advantage of this system is, can ad infinitum adjust the speed and the swing of beater, and some occasion is desirable just for this.
Also have, replace gear reduction and crankshaft system, can reduce the size of the front portion of extruder greatly with hydraulic system of the present invention.System of the present invention does not have long connecting rod and bent axle, but compact on the whole.Therefore, extruder of the present invention can be with the less scope of turn-taking work in narrow region.
Use hydraulic control, this extruder can be set in arbitrary needed speed setting value.This makes this extruder can carry out work more accurately in narrow and limited space.
Those skilled in the art that can understand, and can make many modification within the spirit and scope of the present invention.
