Abstract
The present invention aims to provide a method and apparatus suited for advantageously generating the reciprocating compacting movement needed in a concrete casting machine so as to offer a simple technique of adjusting or changing the amplitude of the compacting movement as required. The invention is based on generating the compacting movement with the help of two rotary shafts (14, 12) of which the primary shaft (14) has a primary eccentric member (18) adapted thereon and the secondary shaft has a secondary eccentric member (20) adapted thereon. The movement of the primary eccentric member (18) is transmitted to the secondary eccentric member (20) by means of a lever (19), whereby the eccentricity of both eccentric members determines the angle of the reciprocating rotation of the secondary shaft (12) and, thus the stroke length of one or more crank levers (11) mounted thereon. The crank levers (11) are connected to the members that are desired to perform a reciprocating movement, e.g., swinging levers (5) moving the core-forming trowel members (4).
Description
Microscler concrete product is to make with squash type moulding press or the board-like moulding press of sliding die as hollow core slab.Moulding press comprises a circular cone loading hopper that has one or more conveying worms in its lower section.Conveying worm is often being followed a core shaping trowel spare, and this trowel spare also has an additional functionality to play final trowel spare effect, the core chamber in the support product.Core shaping trowel spare combines with vibrator or similar system for compacting that the concrete that is used for casting is pressed into by casting model and core shaping shape that trowel spare limits.In addition, moulding press has a last trowel beam as the model top edge, and the side of model also often is designed to side trowel beam.During molded, trowel beam compacted concrete mixed material also carries out surfacing to moulded product.Except trowelling or increasing, also can adopt vibration to come compacting.The extrusion pressing type moulding press is designed to continuous molding machine, and the reaction force by conveying worm moves forward at the top of model.
In other modes, can by vibration limit the product of pour into a mould model surface or, under the situation of production hollow core slab, vibrator is installed in the core shaping trowel, realize compacting to the concrete mix material of pouring into a mould.Do not adopt vibration, slower the moving of the different parts of the concrete mixture moulding press that compacting also can be poured into a mould by working in realizes.Such compaction movement can be by being installed in the conveying worm end the lateral shift of core shaping trowel spare rotatablely move and/or the cyclic deformation of said trowel spare is realized, obtain the compression of concrete mixture thus by the cross section that changes trowel spare.For the trowel spare of non-circular cross sections, rotatablely moving of circulating and reversible is used for compacting.All these moulding presses are characterised in that, realize concrete compacting by the low frequency mechanical movement, thus, the mutual motion between the concrete material particle is produced by machine part motion rather than the shear stress that produced by the impact between the concrete material particle.
In the art, above-mentioned debulking methods generally is called work compacting (working compaction) or shears compacting (shear compaction), one of it is useful is, even under the stroke of the low order of magnitude, the motion of concrete material particle and to move also will be big, that is to say, under the low frequency movement of moulding press parts, obtain the noise-less operation of moulding press.
The principle of low frequency compaction movement has also obtained further developing on the moulding press that has the core molded component with circular cone or wedge-shaped surface, and by the low-speed motion of core molded component on molded flow direction, concrete is compacted.In fact, compacting is to utilize the reciprocating motion of amplitude 5-50mm frequency 1-10Hz to realize, amplitude and the frequency used when this amplitude and frequency ratio vibration are low.In order to improve the compacting friction, moulding press has used wedge shape or the trochoidal surface that has taper or taper on molded flow direction, and said district is as compacted region.
Compacting has big influence on the final mass of product.In compacting process, the particle of producing concrete mixture is very important, that is, concrete material moves relative to each other, present the common state of maximum packing density to allow them, thereby concrete is compacted.This purpose can realize by the actuating pressure and the gravity of mechanical part.Because purpose is to use optimum compacting mode for molded specific product and concrete material, the amplitude of compaction movement and frequency can alter a great deal.In the moulding press that is equipped with the mechanical ramming parts, the frequency of compaction movement and amplitude can be 1-200Hz and 50-0.005mm.In general, frequency high amplitude more is just low more, and vice versa.
Compaction movement may change in a very wide scope in the effect on the concrete mixture of being poured into a mould, and under different condition the result by using different amplitudes to obtain.In the compacting of concrete mixture, be typically and obtained good compacting, a large amount of concrete materials can be under low frequency very with good every motion, concrete material in a small amount requires to use high vibration frequency under short arc.The particle size distribution range that the composition of the concrete mixture of standard comprises is wide, and is big until concrete material particle 16-32mm from whole powdery bonded particulates.By changing particle size and granular materials type and their quantity in the compound, just may produce the product that is suitable for all purposes.Yet, for certain purposes, in order to obtain having the preferably end product of possibility performance from concrete mixture, compound must just should come compacting with the compaction movement with correct amplitude and frequency for each given compound with the mode compacting that said compound is optimized.The compacting of concrete mixture has great influence to the intensity and the homogeney of final products.
Now, adjust and change the compacting frequency ratio and be easier to, because, for example utilize frequency converter can be controlled in the big rpm scope as the motor of vibrating device power source.Yet in fact, by taking to produce the compacting frequency and the amplitude of acceptable good final result, must compromise in the concrete compacting.Usually, be indifferent to concrete material different designs ratio composition, just, under the situation of the relevant ratio of composition and the particle size distribution of employed concrete material or other mixture performance or variation, the compacting parameter remains unchanged.When the performance of the concrete material of not considering to be poured into a mould is carried out compacting, product compaction is relatively poor or have a very high compaction energy must consume to obtain desired consolidation effect.Use high compacting power will cause the wearing and tearing and the stress of mechanical device, thereby cause more frequent maintenance, and just require to indicate the moulding press size in its design phase for heavily stressed.
Usually control compacting efficient by the frequency that changes compaction movement.When the amplitude of compaction movement did not change synchronously with the variation of frequency, FREQUENCY CONTROL mainly can influence the compacting motivation level separately, just, passes to the amount of energy of concrete mixture.FREQUENCY CONTROL considers that neither the performance of concrete material do not consider the size or the Size Distribution of concrete material yet.Simultaneously, present control method can not provide the control fully of compacting process, therefore, in order to obtain good consolidation effect, uses under unnecessary a large amount of energy optimization modes there is no need, and can utilize the performance of different concrete materials.
An object of the present invention is to provide a kind of method and apparatus that in the concrete molding machine, can produce needed reciprocal compaction movement, so that a kind of simple technique of regulating or change the compaction movement amplitude on request to be provided.
Purpose of the present invention can realize that these two turning cylinders are the countershafts that have the main shaft of first eccentric part on it and have second eccentric part on it by producing compaction movement by means of two turning cylinders.By connecting rod the motion of first eccentric part is passed to second eccentric part, the off-centre of two eccentric parts has determined the back and forth angle of rotation of countershaft thus, thereby has determined the haul distance of one or more crank connecting links mounted thereto.Crank connecting link is connected on the parts of expecting to move back and forth, for instance, and the swing connecting bar of mobile core shaping trowel spare.
More particularly, device according to the present invention is characterized in that what claim 1 characteristic was stated.
In addition, the method according to this invention is characterized in that what claim 11 characteristic was stated.
The present invention has great benefit.
The invention enables for different concrete materials and be optimized compacting power and application technology becomes possibility.According to the present invention,, can control compacting process in a different manner by stroke amplitude control complementation with traditional FREQUENCY CONTROL.If the performance of concrete material or component ratio change, for the new component of concrete material, the amplitude of compaction movement and frequency can be readjusted rapidly and be optimal values.If other components of the composition of concrete material or concrete mixture have changed, the compacting parameter can be readjusted, therefore must be destroyed without any product, but the substitute is, after concrete material design changes, make immediately or almost the product of production good quality immediately become possibility.Owing to improved consolidation effect, just can under the situation of not sacrificing end product quality, use the raw material of more expensive price, because the defective of raw material can compensate by the effect of improving compacting.Therefore, the present invention can save product cost.Need less compacting power to mean lower energy consumption, and stress and the wearing and tearing less to moulding press.Lower compacting motivation level also produces less noise.The present invention provides the device of compaction movement to have more cost efficiency than for example having with hydraulic cylinder.Yet hydraulic means can be used in the reciprocal compaction movement of realizing variable amplitude, and this configuration will need the control system of a high power capacity pressure system and a complexity.

Referring now to Fig. 1, expression is an extrusion pressing type moulding press here, and an one compaction movement is to be provided by the swing of core shaping trowel spare 3 reciprocating motion.The function of compaction movement and such extruder is at EPO patent application NO.0, described in 677,362, and its copy is attached to the application's back.The framework 1 of moulding press is connected with the model 2 that is limited by mould walls 7, and said model has one to be used for infeeding mouthfuls 8 with what concrete materials was introduced model cavity.Infeed mouth 8 and limit the axle 10 that also can pass conveying worm 3 by rear wall 9.The end of conveying worm 3 is connected with core shaping trowel spare 4, trowel spare 4 have can form the shape in the inner required cross section core of the hollow core slab of casting chamber.In the embodiment of this type device, compacting is to utilize the compaction movement of trowel spare 4 to realize specifically, product as beam or real central layer must use some, and other bear the parts of compaction movement, because this type of mechanograph can not use core shaping trowel spare.
The oscillating motion of core shaping trowel spare 4 realizes by means of swing component 5.Swing component 5 is used for the axle 10 of support helix conveyer 3, and is connected with the framework 1 that installs by two connecting rods 6.The oscillating motion of typical core shaping trowel spare 4 can be at the EPO patent application NO.0 that is quoted, and the guiding of the said connecting rod 6 described in 677,362 obtains down.Swing component 5 be installed in the crank connecting link 11 of axle on 12 by an eccentric part 13 and link to each other.The countershaft effect of axle in the 12 starting power chains, and be installed in framework 1 on the bearing of rotation on the bearing block 15.Main shaft 14 be installed in a similar fashion framework 1 on the bearing of rotation on the bearing block 16, and in the top of countershaft 12.What main shaft 14 was included in its other end is connected to axle suitable parts 17 on motor or the similar power source.And in the illustrated embodiment, said parts 17 are pulley concial disks, and any traditional power transmission mechanism all can be used to driving shaft.
An end relative with pulley concial disk 17 on the main shaft 14 disposes first eccentric part 18 that is installed on the bearing, and a crank connecting link 19 is arranged on these parts 18.Be installed in equally on the bearing, the other end of crank connecting link 19 is connected with an eccentric part 20 that is configured in countershaft 12 ends.First eccentric part 18 has an eccentric a, and in this illustrated embodiment, the off-centre of eccentric part 18 is adjustable.Eccentric adjusting for example can be regulated by screw and be realized, so eccentric part can regulate by coaxial eccentric disc with respect to the pivot of alignment of shafts axle, and coaxial eccentric disc can change its mutual alignment, or uses the described adjusting flange in this paper back.Usually, when in case of necessity, also just enough with the amplitude of manual adjustments compaction movement.Significantly, in when operation, if need remote control or control from the machine control panel, also can carry out eccentricity control, the adjustable eccentric parts compensate with a suitable exciting bank.The machine cost naturally also will be owing to there being such remote control to improve, but machine operation person requires, also can be with simple method realization.Second eccentric part 20 has an eccentric b, and the value of b must be greater than the off-centre of first eccentric part 18.
The function of this device is as follows.For example main shaft 14 rotates by motor.The rotating speed of main shaft 14 depends on the compacting frequency, its adjustment can by means of, for instance, the frequency changer that is connected with motor is easy to realize.The central shaft rotation of the definite track of eccentric a along main shaft 14 pressed in the end (first end) of the connecting rod 19 that is connected with first eccentric part 18, and drives the end of the connecting rod 19 that is connected with second eccentric part 20.The track of connecting rod 19 ends that are connected with second eccentric part 20 is determined by the ratio of length of connecting rod and the position of eccentric part between the off-centre of two eccentric parts, the eccentric part.In the illustrated case, the eccentric b of second eccentric part 20 is less times greater than the eccentric a of first eccentric part 18, the end (second end) of the connecting rod 19 that is connected with second eccentric part 20 just can not stride across the central axis of countershaft 12 thus, the substitute is, and has to be movable in a reciprocal manner.This reciprocating motion passes to connecting rod 11, and this connecting rod 11 is installed on the countershaft by the 3rd eccentric part 13, and connecting rod is at the other end that is connected with tilting member 5 thus.Like this, rotatablely moving of main shaft 14 just converts that tilting member 5 and core subsequently form trowel spare 5 and the oscillating traverse motion of the conveying worm 3 that is connected with the there to.At the EPO patent application NO.0 that quotes, in 677, the 362 described modes, the linkage 6 of tilting member 5 is being controlled the motion of core shaping trowel spare 5.
If another eccentric b is changeless words, the angle [alpha] of countershaft 12 crankmotions is by the eccentric a decision of first eccentric part, and vice versa.In addition, for the set-point of these variablees, the amplitude of fluctuation of tilting member by the connecting rod between the eccentric part 13 on connecting rod 11 that is connected with swing component 5 and the countershaft 12 that is installed in drive link than determined.Equally, swing arm 11 is variablees about the position of countershaft 12, and it influences the haul distance of tilting member 5.In this paper embodiment described later, utilized this possibility.
In above-mentioned example, main shaft 14 has produced the compacting frequency of 25Hz with the speed rotation of 1500r/min.Be configured in and be used to set the screw of eccentric a on first eccentric part 18 or the adjustable extent of slit adjuster may be, for instance, combine, be 0-15mm with the off-centre of the 20mm of second eccentric part.So, swing arm 11 and be installed in connecting rod between the eccentric part 13 on the countershaft 12 than being so definite promptly when the eccentric a of first eccentric part is made as maximum, will obtain desired maximum compacting stroke amplitude equally.Then, the eccentricity value of said first eccentric part is made as 0, because first eccentric part is consistent mutually with the central point that rotatablely moves of second eccentric part, so that the end of connecting rod 19 keeps static, connecting rod 19 is connected with first and second eccentric parts 18,20.In the case, just can realize the stepless control device of compaction movement 0 to the range amplitude.
In the device shown in Fig. 3-6, stroke amplitude control is implemented in a kind of slightly different mode.In the present embodiment, the eccentric a of first eccentric part 18 and second eccentric part 20, b is changeless, amplitude control is to realize about the position of second eccentric part 20 by changing countershaft 12 and swing arm 11 mounted thereto.For other details, the adjusting flange 21 on being installed in second eccentric part 20, the device of present embodiment and above-described similar.Fig. 6 represents swing arm 11 being connected by eccentric part 13 and countershaft 12.The quantity of second connecting rod 11 depends on the quantity of conveying worm 3 and core shaping trowel spare 4.Usually, use a large amount of conveying worms, the conveying worm that needs larger amt at the moulding press of broad is to adapt to the slab of producing the multicore vestibule.In the embodiment shown in fig. 3, swing connecting bar 11 is suitable for being offset phase circular motion (cycles of offset phases), and when needs, by changing their driving connection angles on countershaft 12, the motion of conveying worm 3 and its core shaping trowel spare 4 can change mutually.
Figure 4 and 5 illustrate by one and regulate the principle that flange 21 is regulated core shaping trowel spare haul distance.Here, second eccentric part 20 and regulate flange 21 collar of all porose 22 and 23 on its circumferential position.Between the hole with identical apart from interlaced arrangement consistent so that the hole is provided with in different angles, when regulate flange 21 or, particularly during 20 rotations of second eccentric part.Regulate 0 angle between the flange 21 and second eccentric part 20 and be meant angle when desired tilting member impact direction is parallel to the drawn straight line of central axis of pivot by being installed in the eccentric part 13 on the swing connecting bar 11 and countershaft 12.In fact, this means and regulate flange and horizontal plane to directly or substantially to directly.In the illustrated embodiment, the connecting rod eccentric stiffener rotates around countershaft 12 with a fixed angle α all the time, and α is 49.24 ° in schematic structure.
The stroke amplitude of tilting member 5 and the core shaping trowel spare 4 that driven thus depends on the position of the swing arm 11 that is installed on the countershaft.Center at anglec of rotation α, when the center line of the eccentric part that drives swing arm 11 is parallel with the motion of tilting member 5, the rotation of countershaft 12 is mainly at the transversely driving swing arm 11 of the longitudinal direction of desired compaction movement, thus, when connecting rod eccentric stiffener during in its dead-centre position, the compacting stroke amplitude keeps little numerical value, and under illustrated case, the dead point is meant top dead.And the center line of the eccentric part 13 on being installed in countershaft 12 is when becoming a big angle with compaction movement, and the swing arm 11 that is connected with said eccentric part mainly moves on the direction of compaction movement being parallel to, thereby causes big stroke amplitude.This can be applicable to stroke amplitude control, can be about 20 rotations of second eccentric part so have adjusting flange 21 countershaft 12 also mounted thereto.So, the lock hole 22,23 of second eccentric part 20 and the customization of regulating flange 21 allows countershaft 12 to lock on different positions, so can find a suitable position, be installed in the stroke amplitude that eccentric part on the said axle converts countershaft 12 reciprocating angle [alpha] to a desired compaction movement.For instance, 0 angle position of stroke adjustment can be chosen as the top dead or the bottom dead center of the mechanism that is made of the eccentric part 13 of countershaft and swing arm, and adjusting angle β is and regulates the angular displacement of flange 21 from said 0 angle position thus.
The presented in diagrammatic form relation of the stroke amplitude of mechanism size when adjusting angle is β that provide among Fig. 5 of Fig. 7.Significantly, these sizes are described to give an example, and adjustable range can change between different machines and driving mechanism design.
Except top description, the present invention can implement with other embodiment.
For instance, employed in the above-described embodiments eccentric part can replace with the mechanism that can produce equal actuation movement of crank mechanism or other types.In this article, vocabulary " eccentric stiffener " should be broadly interpreted as, and is suitable for rotatablely moving of at least one machine part converted to, and along desired trajectory, point is as the device of any kind of the forced movement of crank tie point.In above-mentioned second embodiment of the present invention, can arrange by the eccentric part that all driving swing arms 11 are installed attached to the adjusting flange on second eccentric part, and it has the secondary locking parts that are installed on the countershaft.When this layout made the adjusting of moulding press very difficult, on the other hand, it also provided the possibility of each core shaping trowel spare being set different haul distances.Significantly, the present invention also can be used for except that the independent compaction movement that is produced the core shaping trowel spare purpose that drives.If compaction movement only needs compacting parts as a top trowel beam, the connecting rod of so said parts or arm can directly be connected with second eccentric part, in this case, this second eccentric part had not only played second eccentric part but also had played the driving eccentric part of swing arm.If replace eccentric part mechanism with toggle, the core that first and second eccentric stiffeners can be between axle.Significantly, using under big other situation of compacting powered stage, can be installed in parallel a large amount of eccentric stiffeners.For instance, when compaction movement need pass to independent compacting parts, what the axle in the device basically can be than shown in the chart was short.
