Description
Technical field
The present invention relates to a kind of diesel hammer, this diesel hammer has:
A) cylinder;
B) piston that in cylinder, is directed movably;
C) impulse member/ram that is directed movably in cylinder is below this impulse member of the operating position of diesel hammer is arranged on piston;
D) working chamber, this working chamber are surrounded by the end face that is positioned at cylinder interior and the piston end surface of impulse member in the axial direction;
E) fuel supply system, by this fuel supply system can be in each working cycles to the fuel, particularly diesel oil of working chamber input scheduled volume.
Background technology
This diesel hammer that is also referred to as diesel pile hammer is used for particularly at the foundation construction of construction industry various types of stakes being squeezed in the ground as concrete pile, Tie Liang, sheet pile wall element etc.
In order to start this diesel hammer, piston is upwards drawn and discharge by means of releasing device at the certain height place, then piston falls under action of gravity.Piston is handled a petrolift when falling, supply with fuel, particularly diesel oil to one or more nozzles thus, and described nozzle sprays into fuel the working chamber of cylinder.
Air when piston falls in the cylinder working chamber is compressed and is heated so thus, makes the fuel/air mixture that is present in the working chamber light, explosion type ground burning thereupon.
The explosion energy that discharge this moment upwards gets rid of piston to new working cycles on the one hand again, on the other hand stake is driven underground.
For this diesel hammer, known two kinds of types that by different way fuel sprayed into working chamber.
For first kind of spray regime---high-pressure injection, fuel under high pressure sprays into the working chamber of cylinder usually with the form of the fuel fog of finer atomization between the piston compression period that air is fallen.This mist and air form the mixture that can light together.When high-pressure injection, fuel is during compression process, in case be compressed when air reaches the temperature that is enough to the fire fuel mixture and just light.
Burning by explosion type produces high pressure in working chamber, make piston deceleration on the one hand by this high pressure.This combustion pressure acts on the impulse member on the other hand, and impulse member applies power to stake, thus stake is driven underground.
Compression process stops when piston is run into impulse member at the latest, and wherein the piston of having been braked by the combustion product that expands before bumping against on the impulse member strikes on the impulse member with whole kinetic energy.Sometimes, particularly when ground is hard, even may occur that promptly piston is not run into impulse member at all, and not have prior the contact with impulse member just under the effect of burning gases by again to upthrow.Under this condition, only impulse member is acted in the stake by the burning air cushion.
Therefore, the stake of adopting the diesel hammer of high-pressure injection not too to be suitable for counterweight is driven piles or is not suitable for the unmanageable ground soil condition with hardpan.
In addition, this diesel hammer temperature when work is very high, and overdue combustion may take place high-pressure injection system when overheated.In addition, the structure of more complicated need often be keeped in repair and have in this system.This brings such shortcoming, and the diesel hammer that promptly adopts high-pressure injection is on-the-spot in the building site to be difficult to or even can not to keep in repair at all.
The advantage of high-pressure injection is the burning of good comparison noresidue and the favorable starting performance of diesel hammer, and has good piling effect when soil layer is soft.
Second kind of spray regime is so-called impact atomizing, relative with high-pressure injection it also can be called low-pressure fuel injection.
In this case, fuel sprays into working chamber with the form of fuel beam with lower pressure usually when compression process begins, and the face (Kraftstofflache) that at first acts as a fuel then places on the upper surface of impulse member.
Air in the working chamber is compressed by the piston that falls, till piston bumps against on the impulse member.Also light the compressed air of high temperature in this state by the piston area atomizing of collision at this instantaneous liquid fuel.Then by the blast piston to upthrow, can begin next working cycles thereupon.
Only brake by being in the working chamber and by the air of piston compression the whereabouts of piston till on impinging upon impulse member.This means that the kinetic energy major part of piston is delivered on the impulse member, therefore can be under applying in the stake under the identical situation of piston weight than situation in above-mentioned high-pressure injection much higher impact force.The bump of piston impact part occurs in before the fuel combustion in time.
Adopt the diesel hammer of low-pressure fuel injection not too to be applicable to the little occasion of ground earth resistance.So because the less compression of formation resistance reduces, this is because the compression pressure of being set up is delivered in the stake by the impulse member that moves downward in this case.Therefore in fact working chamber enlarges, and this can pay the cost that compression pressure reduces.
Therefore burn when ground earth is soft and only carry out with the quality that decreases, this may cause not wishing the generation of the residue (carbon black, unburned fuel in burning gases) that occurs, and these residues can increase the weight of environmental pressure.
The advantage of impacting atomizing is effectively to have utilized to impinge upon the kinetic energy of piston on the impulse member because piston is rigid.It is overheated to adopt the diesel hammer that impacts atomizing to be not easy in addition, compares high-pressure injection diesel hammer not easy break-down and easier operation.
Such defective of having to up to now accept for diesel hammer promptly can only be considered specific site condition all the time according to the diesel hammer of one of two kinds of operating principles work.If conclude ground earth character at the scene with preplanned different, then otherwise must use the equipment of non-the best to work on, otherwise must purchase other diesel hammer, this causes the cost of the loss of time and Geng Gao.
Summary of the invention
The objective of the invention is to invent a kind of diesel hammer, this diesel hammer can be used for different ground soil conditions with good impact effect under good burning quality condition.
Realize by such method for this purpose of diesel hammer that starts described type, promptly
F) fuel supply system is designed to like this, makes fuel spray into working chamber with first spray regime as the fuel fog of atomizing and with second spray regime beam that acts as a fuel.
Make diesel hammer when soft ground soil condition, can use high-pressure injection work thus, and available above-mentioned impact atomizing type work under the situation of hard formation.
Thereby guaranteed to make in---this burning optimization is also partly relevant with ground earth resistance---validity of diesel hammer and the soft or hard of ground earth layer to be complementary at burning optimization.
If the fuel fog of first spray regime is substantially perpendicular to the direction of motion of piston and flows into working chamber near the upper surface of impulse member, then is favourable.Realize the good distribution of fuel fog in working chamber thus, this makes formed fuel/air mixture well and effectively burn all.
The working chamber that the fuel beam of second spray regime sprays into cylinder like this is favourable, promptly impinge upon the fuel beam tilt impulse member on the end face of piston one side.Thereby guarantee that liquid fuel is distributed on the described end face well, this makes fuel atomize better when the piston slap impulse member, thereby facilitates good and effectively burning.
The diesel hammer that can change easily aspect structure is obtained by such form of implementation, wherein fuel supply system comprises at least one high-pressure injection device and at least one low-pressure fuel injection device, and they can be supplied to a certain amount of fuel via a pipeline and by at least one petrolift that is communicated with fuel tank that enters the mouth respectively in each working cycles of diesel hammer.
Can advantageously adopt known high-pressure injection and low-pressure fuel injection parts to realize diesel hammer of the present invention in this way.
If especially can regulate by the fuel quantity of high-pressure injection device and low-pressure fuel injection unit feeding respectively, then be favourable by petrolift itself.The difference of base area earth hardness thus, the impact strength that can make diesel hammer is complementary with different ground soil conditions.
Select as another kind, also can adopt the choke valve that to control or at controllable valve aspect the opening time.
If the piston control or operating fuel pump or the injection valve that fall well and at the fuel that reliably mates with the working cycles of diesel hammer aspect the time spray just can realize function so.
If all supply with a MIN fuel quantity, just can prevent simply that so the common very fine nozzle of high-pressure injection device is blocked at the petrolift of each working cycles inner high voltage injection apparatus.Therefore in each working cycles, all there is fuel to flow through nozzle, thereby disposes dirt or keep not existing dirt.
If make the piston end surface reduction/indentation (abgesetzt) that limits cylinder working chamber, then can provide a combustion chamber that can guarantee active combustion by the ring-shaped step portion that is positioned at radial outside.If described piston end surface is fitted on the inner face of impulse member, so formed combustion chamber is annular, and has less volume.
According to another kind of improvement project of the present invention, the working chamber that fuel had not only sprayed into cylinder as the fuel fog of atomizing but also the beam that acts as a fuel in the 3rd spray regime.
Can be implemented in the transition between first and second spray regimes like this.

Piston 14 moves in cylinder 12.Be embedded in movably in the lower end of opening of cylinder 12 with the coaxial impulse member 16 of piston.The ring-shaped bearing unit 20 that the lower end of cylinder 12 has by means of screw---representing one of them with Reference numeral 18 in the drawings---fixes.Shaft-like section 22 of impulse member 16 middle parts is directed, and has the external diameter littler than the internal diameter of cylinder 12 hermetically and movably in described bearing unit.
Be formed with the shock plate 24 that is positioned at below the cylinder shaft-like section 22 lower end, its following interface 26 that is positioned at outside protrusion when work with stake to be squeezed into upper end acting in conjunction as concrete pile, Tie Liang, sheet pile wall element etc.
Be formed with the piston section 28 with a plurality of axially spaced O-ring seals 30 in shaft-like section 22 upper end of impulse member 16, described sealing ring moves on the internal valve 32 of cylinder 12.The perisporium of the downside of the upside of piston section 28 and piston 14 and cylinder 12 surrounds working chamber 34 together.The end face 36 towards the working chamber 34 of cylinder 12 of impulse member 16 is ground to the plane that has flat fuel pit (Brennstoffmulde) 37.
Between the bearing unit 20 of the shock plate 24 of impulse member 16 and cylinder 12, be provided with damping ring 38.Between downside, has another damping ring 40 that works near the bearing unit 20, in the piston section 28 of the upside of bearing unit 20 and impulse member 16.
Above impulse member 16, move in cylinder 12 the following working end 44 of being furnished with isolated vertically O-ring seal 42 of piston 14.
The following free end face that polishes 46 of piston 14 reduces by the ring-shaped step portion 48 that is positioned at radial outside, makes end face 46 when piston 14 form the combustion chamber of a loop configuration when being fitted on the end face 36 of impulse member 16.
The working end 44 of piston 14 is formed on the quality section 50 of piston, and this quality section extends in the unshowned herein epimere of cylinder 12.
For the first time jigger lifting piston 14 with the starting diesel hammer, quality section 50 has unshowned driving convex shoulder herein, one herein the releasable hook of same unshowned lifting appliance can act on this convex shoulder.
On the perisporium of cylinder 12, be provided with and have the petrolift 53 that schematically shows and the high-pressure injection device 52 of high pressure nozzle 54.At the upper end position as shown in the figure of impulse member 16, promptly when the last ring surface 56 of the shock plate 24 of impulse member 16 is fitted on the damping ring 38, the nozzle 54 of high-pressure injection device 52 just in time leads to the working chamber 34 of cylinder 12 above the end face 36 of impulse member 16.
Except high pressure nozzle 54, can also on the perisporium of cylinder 12, other high pressure nozzle be set (especially on equal height) distribution.
High-pressure injection device 52 particularly its nozzle 54 is designed to like this, makes the diesel oil that will be supplied to it under high pressure spray into the working chamber 34 of cylinder 12 basically as the mist 76 of atomizing.Wherein nozzle 54 is so directed, and the direction of motion that makes diesel oil be substantially perpendicular to piston 14 sprays into.
Another petrolift 60 that drives by the operation push rod 61 of pretension in cylinder 12 inside when piston 14 falls is connected with low-pressure nozzle 66 by pipeline 64 at outlet side, and constitutes low-pressure fuel injection device 68 with this low-pressure nozzle.Petrolift 60 is communicated with the fuel tank 62 that is filled with diesel oil.Low-pressure fuel injection device 68 towards the direction of cylinder 12 upper ends and high-pressure injection device 52 turn up the soil at interval vertically on the perisporium that is arranged on cylinder 12 and within.Its nozzle 66 is design and directed so, makes the fuel of output roughly be on the end face 36 that middle ground is injected in impulse member 16 with continuous basically beam.
Herein also can be on the circumference of cylinder 12, especially with on sustained height, distribute other additional low-pressure nozzle of low-pressure nozzle 66.
That is high-pressure injection device 52, low-pressure fuel injection device 68 and fuel tank 55 and 62 constitute fuel supply system together on the whole.
Petrolift 53 and 60 can regulated aspect its conveying capacity independently of each other, makes the fuel supply to high pressure nozzle 54 and low-pressure nozzle 66 change serially, as following also to illustrate.
As can be seen, above low-pressure fuel injection device 68, the upwardly extending instrumentation tubes joint 70 and 72 that tilts passes the perisporium of cylinder 12.Suck combustion air and discharge burnt gas by these unions.
Fig. 2 and 3 illustrates the petrolift 60 of low-pressure fuel injection device 68, and its operation push rod 61 is in two different original positions shown in it.
According to the difference of operation push rod 61 original positions, its operating surface 86 is as stretching into the inner chamber of cylinder 12 fully appreciable among Fig. 2, or stretches into cylinder inner cavity with lower area as shown in Figure 3.
Between pump piston 80 and operating portion 82 roughly in the middle of the place, up a baffle plate 88 links to each other with piston rod 84, and cooperates with the baffle plate that can radially adjust 90 that is fixed on the housing of stroke adjusting device 92.Baffle plate 90 moves on the screw mandrel 96 that radially outwards stretches by screwed hole 94, and this screw mandrel can drive rotation by the servomotor 98 that only schematically shows in the drawings.
Pump piston 80 moves in the pumping cylinder 100 in the perisporium outside that is arranged at cylinder 12, and described pumping cylinder has the fuel outlet 102 and the fuel inlet 104 that is connected with fuel tank 62 fluids that is communicated with nozzle 66.
The pump piston 80 that makes that Fig. 2 illustrates baffle plate 90 has the position of its range.This means that in this position of baffle plate 90, the fuel quantity by petrolift 60 outputs in each stroke is maximum.
If now from position shown in Figure 2, just the screw mandrel 96 of rotation adjuster 92 is radially outwards motion of baffle plate 90.The stroke of pump piston 80 in pumping cylinder 100 reduced, thereby the volume of the working chamber 108 of petrolift is reduced, this fuel quantity that causes can carrying in each stroke reduces.Fig. 3 illustrates such position of stroke adjusting device 92.
High-pressure injection device 52 can design according to the foregoing description of low-pressure fuel injection device 68.The element of high-pressure injection device 52 has corresponding Reference numeral in Fig. 2 and 3.
Therefore, can pre-determine by the affiliated relevant position that is fixed on the baffle plate 90 on the housing by high-pressure injection device 52 or the fuel quantities that are transported to by low-pressure fuel injection device 68 in the working chamber 34 of cylinder 12.
The electronic-controlled installation of the fuel quantity of the working chamber 34 that is used to be supplied to cylinder 12 shown in Figure 4, wherein with Fig. 1 to 3 in the corresponding element of element represent with identical Reference numeral.
Be supplied to the fuel quantity of high pressure nozzle 54 and low-pressure nozzle 66 to be input in the computer 114 that has display monitor by keyboard 118.Information about existing ground soil condition also can be used as the input parameter acquisition, calculates the data that are suitable for high-pressure injection device 52 and low-pressure fuel injection device 68 with appropriate software by means of these information then.
The duration that computer 114 is opened by input data computation electromagnetic valve 110, open the duration sprays into specified quantitative to the working chamber 34 of cylinder 12 by high pressure nozzle 54 or low-pressure nozzle 66 fuel according to it thus.
The opening time of being obtained by computer flows to control module 120, and this control module sends the opening time respectively to as control signal the controlled monostable element 122 of high-pressure injection device 52 or low-pressure fuel injection device 68.
Therefore, electromagnetic valve 110, fuel reservoir 112 and monostable element 122 constitute the controlled fuels sources of conveying capacity together.
Above-mentioned diesel hammer 10 is in the following manner:
In initial state, piston 14 is by carrying but unshowned holding device rises to one is in top position.After being released, piston falls under action of gravity therefrom, closes instrumentation tubes joint 70 and 72, and handles the operation push rod 57,61 of high-pressure injection device 52 or low-pressure fuel injection device 68 with its end face 46.
If adopt, this means that so piston 14 hits on the operating surface 86 of the operating portion 82 of operating push rod 61 from the top in injection apparatus 52 shown in Fig. 2 and 3 or 68 form of implementation.Move in the left side of push rod in Fig. 2 and 3 when piston 14 continues to fall.Pump piston 80 is moved to the direction of the outlet 102 of pumping cylinder 100, thereby the fuel in the working chamber 108 is flowed to nozzle 54 or 66, and be ejected in the working chamber 34 of cylinder.
In working chamber 34, perhaps form combustible mixture by fuel droplet and air by high-pressure injection or by impacting atomizing.Now nozzle 54 and 66 based on fuel pumps 53 and 60 setting is different, sprays a certain amount of diesel oil in mode above-mentioned to the working chamber 34 of cylinder 12 respectively individually or jointly.If one of injection apparatus 52,68 should be to working chamber 34 burner oils of cylinder 12, then the control by servomotor 98 is radially outwards moved its operation push rod 57 or 61, till corresponding operating portion 82 no longer extend in the inner chamber of cylinder 12.
When the electronic-controlled installation that adopts as shown in Figure 4, programme by 114 pairs of expectations of computer parameter.If wherein one of two injection apparatus 52,68 should be to working chamber 34 burner oils of cylinder 12, then corresponding monostable element 122 being controlled to pulse width so in this case is zero, makes that corresponding solenoid valve 110 is not opened when piston 14 falls.
Along with piston 14 impinges upon on the impulse member 116 and/or by the air cushion between piston and the impulse member (acting on the impulse member), a downward power is applied on the impulse member and by this impulse member and acts in the stake, this power further pushes stake in the ground.
In the moving upward of piston 14 that the burning of the explosion type by diesel oil is subsequently triggered, piston is opened instrumentation tubes joint 70,72, burning gases are expanded and flows out by instrumentation tubes joint 70,72.Piston 14 continues to upthrow, till it arrives its upper end position and repeats described working cycles under same situation by the fresh combustion air of instrumentation tubes joint 70,72 suctions now.
Therefore, diesel hammer can be alternatively only by means of high-pressure injection device 52 with the first spray regime work as the atomized fuel mist, only by means of the second spray regime work of low-pressure fuel injection device 68 with the beam that acts as a fuel, or by the two combination with not only as the 3rd spray regime work of the atomized fuel mist but also the beam that acts as a fuel.It can be complementary with different ground soil conditions thus.
Usually have soft ground soil condition at the piling initial stage, that is a little ground earth resistance, therefore during this time diesel hammer 10 only or mainly to adopt high-pressure injections to come work by means of high-pressure injection device 52 be favourable.Low-pressure fuel injection device 68 also can be supplied with small amount of fuel in some cases, thereby adopts the impact atomizing that had illustrated auxiliaryly.
If stake arrives the therefore common harder soil layer that supporting capacity is more arranged, then can improve the deal of low-pressure fuel injection by the fuel quantity that appropriate change is supplied with via low-pressure fuel injection device 68, make the power of piston 14 be directly delivered on the impulse member 16 thus and improve at the active force that is added in the stake, as illustrating.
If become for example sand layer of softer layer again at big degree of depth place ground soil condition, then can correspondingly coordinate ratio by injection apparatus 52 and 68 fuel quantities of supplying with.Therefore, the working method of diesel hammer 10 can be complementary with different and ground soil condition that change individually with action principle, at this moment can guarantee the good and burning completely of diesel oil.
When adopting the work of impact atomizing principles in hardpan, high-pressure injection device 52 preferably continues operation with small amount of fuel in each working cycles.That is to say at the petrolift 53 of each working cycles inner high voltage injection apparatus 52 and supply with a minimal amount of fuel to high pressure nozzle 54.Avoid thus doing usually of high-pressure injection device 52 very thin nozzle 54 stops up owing to combustion residue or other impurity such as lubrication oil residue and can not work again.
In a kind of flexible program, also can only use single pump that the fuel of pressurization is provided, described pump similarly is used for high-pressure injection and low-pressure fuel injection (if possible can pass through pressure reducer or choke valve).
In another kind of flexible program, if wish that the structure of diesel pile hammer is simple especially, and/or the variation of load is little, then also can not use the fuel quantity control device in service continuously.
