Description
The present invention relates to a kind of bulk material leveling apparatus, be used for smooth especially at the taper bulk material pile that when array carriage loads bulk material, forms.This bulk material leveling apparatus has one to be arranged on moving traffic lane top and especially to load and unload the upper frame and a flattening mechanism that links to each other with upper frame of track top, flattening mechanism has a underframe with smooth beam, also be equipped with one on the underframe and be used for fixing following of bulk cargo and sail smooth cylinder or the roller that direction is positioned at the back, also have a lift system that underframe is moved in addition between position, a upper end and lower end position.
This bulk material leveling apparatus is known, is mainly used on the railway car of transportation bulk cargo.Certainly do not get rid of yet and be used for other bulk cargo transportation means, as truck and steamer.Carrying out smooth to the taper bulk material pile mainly is to avoid producing excessive dust in the bulk cargo transportation, simultaneously for security consideration also avoid cargo-carring bulk cargo surface be pine floating and to help making full use of stowage capacity.Known bulk material leveling apparatus is made up of a kind of framework up and down of stable formed steel construction.Two frameworks interconnect by a parallel guides with bolt bearing.Upper frame is fixedly mounted on the corresponding bottom section of loading and unloading track top.The smooth cylinder that underframe is used to smooth beam is installed and is connected on the back, this cylinder is used for smooth bulk cargo compacting.
The underframe of flattening mechanism links to each other with a hoisting crane on being fixed on upper frame with at least one cable wire.This hoisting crane is furnished with a kind of velocity stage of carrying out microrunning.Terminal switch point is equipped with a terminal switch respectively up and down.The operator handles hoisting crane from a control center by keypad.By means of this keypad and visual surveillance, the operator can reach flattening mechanism will carry out the smooth desirable height in top, compartment.Do not carry out on the desired correct height of smooth work if reach, the operator will down open flattening mechanism always so, up to reaching desirable height at once.This process all will repeat on each compartment in case of necessity.
The operator also must be noted that the differing heights in compartment except observing the formation process.If follow compartment after carrying out smooth compartment than the former height, the operator must raise in time according to big young pathbreaker's flattening mechanism of its oad so, otherwise flattening mechanism has the higher threat of being broken by higher compartment, perhaps makes compartment peace its whole structure become very big damage at least.
After formation process finished, the operator drove back to flattening mechanism the stop position of top.
Obviously, handling known bulk material leveling apparatus needs the operator to keep the attention of height, but always unavoidably makes mistakes.
Task of the present invention provides the material spreading cone flattening device that a kind of this paper starts described type, it is work automatically basically, and the operator of assurance device has high safety and handles convenience, has especially prevented from the device of falling state and be in the operating area and arrive between the transport trolley of its operating area to bump.
According to the present invention, above-mentioned task is by solving for non-contact type scanning device of bulk material leveling apparatus configuration.Scanning device links to each other with lift system through a circuit control mechanism, and this circuit control mechanism control flattening mechanism makes it can not contact with the bulk cargo transport trolley.Scanning device of the present invention guarantees that thus flattening mechanism neither can be collided by for example railway car, can not broken by it yet.For scanning device itself also is like this, because work under no touch according to scanning device of the present invention.According to the present invention, if bulk material leveling apparatus is not full-automatic, but can be partial automatization at least, because needn't monitor with human eye formation process again, and no longer include damage that also exists so far or the sort of danger of breaking flattening mechanism.
In the favourable structure of the present invention design, scanning device has one first sweep unit at least, and it is contained on the underframe and surveys target (or object) near underframe.If for example at the heel in this case smooth height of wagon of wanting changes, will be detected this change in advance by first sweep unit so, underframe or flattening mechanism are risen, up to the corresponding height of wanting smooth compartment that reaches afterwards.
Be provided with one second sweep unit in addition, it is contained on the upper frame, detection is in the bulk cargo transport trolley in the flattening mechanism zone, can guarantee thus, if in formation process, follow-up, may clamp-on in the confirmable detecting area of second sweep unit in higher compartment, flattening mechanism can take the stop position of top to with being compelled to so, makes it avoid being damaged thus.Second sweep unit preferably points to downwards this moment.
Also be provided with one the 3rd sweep unit at last, it is arranged on (also being provided with after being preferably in it) a distance before the bulk material leveling apparatus in loading and unloading track or the zone of travelling, surveys the bulk cargo transport trolley of an approaching.These the 3rd sweep units are used for finding ahead of time at next as prescribed not of possible situation, for example with the speed that the increases bulk cargo transport trolley near bulk material leveling apparatus.In this case, will correspondingly detect this situation, make flattening mechanism reach the stop position of top.
When along with all be provided with scanning device against This train is bound for XXX, so just guaranteed that material spreading cone flattening device of the present invention can use in both sides on the one hand, it all is subjected to corresponding protection in both sides and can be touched (or collision) on the other hand.
In addition, in order to improve the safety of flattening mechanism to greatest extent, along with against travel direction at least respectively be provided with two preferably sweep units of upper and lower settings, so both made when certain sweep unit breaks down, also to guarantee to scan always, detected the situation of bulk cargo transportation thus.In addition, utilize the sweep unit of upper and lower settings can also determine two minimum diff-Hs that the compartment is mutual, make the flattening mechanism minimum distance that correspondingly raises, to eliminate this diff-H.Has very big diff-H if determine between the compartment of wanting smooth and the compartment subsequently by first sweep unit of upper and lower settings, so just send a corresponding pulse, make flattening mechanism in the position of reaching under the assistance of lift system above it by control mechanism.
On the concrete structure of this inventive concept, the regulation sweep unit can be super sonic, light or infradred sensor.This sweep unit be used for bulk material leveling apparatus prove well-adapted and cost extremely low.
When lift system had the extremely low rising or falling speed level of at least one high rising or falling speed level and, then the safety that reaches very high degree for flattening mechanism was exceedingly useful.Wherein high rising or falling speed is such design-calculated, and promptly before the bulk cargo transport trolley of an approaching touched underframe, flattening mechanism was wanted and can be moved out from the section scope of this bulk cargo transport trolley.One aspect of the present invention provides a kind of slow work speed level, lift system is raised to flattening mechanism on each height of the bulk cargo of wanting smooth at smooth on period with this speed, and high speed is then adjusted by control mechanism after scanning device is sent a corresponding pulse.At the next big diff-H that under moving, flattening mechanism is in time crossed of determining by scanning device and control mechanism of so a kind of situation with work speed.When detecting the bulk cargo transport trolley of a quick approaching, be exactly this situation.At this moment, the lift system of being controlled by control mechanism then is transformed into high speed from work speed, thereby flattening mechanism is left from the hazardous location in time.The computing value of maximum speed depends on deployment scenarios and the sphere of action and the accessible maximum draw rate of the sweep unit of apparatus of the present invention.Calculate the value of high rising or falling speed and be familiar with, can calculate at an easy rate, also will comprise certain safety factor certainly by formula for the professional.
The bulk material leveling apparatus operated by rotary motion is in the front of a handler, by handler bulk cargo packed in the bulk cargo transport trolley.Among the present invention, lift system so links to each other with this handler through control mechanism, and promptly when handler was not activated after the regular hour, flattening mechanism just automatically was driven to the position of top.Equally also can be provided with like this and being connected of flattening mechanism, promptly when flattening mechanism was not activated behind certain hour, flattening mechanism will be driven to the position of top similarly.This mode that forcibly flattening mechanism is controlled to the stop position of top has guaranteed that flattening mechanism is not unnecessarily to be arranged in the hazardous location, thereby has got rid of the possibility that is subjected to destroy in this time fully.
If will keep the long time on the flattening mechanism position up, then lock it on this position the preferably a kind of mechanical type locking that relates to herein by a kind of corresponding interlocking mechanism.This is because because the error of all misoperations or function, can make that flattening mechanism is non-to descend from the position of top by the people with being willing to.Utilize this mechanical type locking to prevent such misoperation reliably.
If a control mechanism is noted and sent to this blocking by a recording gear in addition, this control mechanism locking is always lived lift system, till blocking is disengaged, so can guarantee when the operator when flattening mechanism has by mistake started lift system under by the situation of locking, flattening mechanism can not destroy mechanical latching wittingly.
For fear of damaging lift system, this lift system is provided with an overload protecting mechanism.If when reaching for example 110% the numerical value of rated load, nominal load, overload protecting mechanism just automatically disconnects lift system.
In order to guarantee that formation process can carry out smoothly and promptly, stipulate in addition, be provided for limiting the emergent up and down limit switch and the limit switch of working up and down that is used in smooth work constrained motion of flattening mechanism largest motion scope.The position of emergent limit switch is a predetermined fixed up and down, and the work limit switch is adjustable.These switches are set are to make device of the present invention automation further.For example when driving into, a bulk cargo transport trolley can determine which kind of altitude range the material spreading cone heap of wanting smooth is positioned on.Just can adjust corresponding diff-H by the limit switch of working up and down this moment, and flattening mechanism just moves between this diff-H scope in the formation process.The bound bit switch has been stipulated maximum motion boundary, can link to each other with terminal switch, and these terminal switches just stop it after lift system arrives each position.Same situation also is suitable for the work limit switch certainly.
In order to make device of the present invention automation further, be provided with measuring mechanism in addition, especially approximate initiator, rotary angle transmitter or analogue, they are used for surveying absolute altitude of having mentioned and each position of writing down flattening mechanism.Certainly, measuring mechanism links to each other with lift system through control mechanism.So just no longer require constantly to regulate lift system, so that reach desired position.Equally also avoided effectively repeatedly occurring because the false judgment that the operator causes.
The very simple lift system embodiment of structure adopts hoisting crane as lift system, and it is contained on the upper ledge and links to each other with underframe through a cable wire at least.Two frameworks then interconnect by two guide rods of swinging that are arranged in parallel at least.Show, adopt in work of the present invention running that not only cost is low by carrying the lift system that heavy-duty machine constitutes, and reliable operation.Can certainly adopt other lift system, for example can consider with rack or by the bar that two frameworks are linked to each other of air pressure or hydraulic operation.
In order to guarantee directly to regulate well flattening mechanism, especially when bulk cargo transport trolley high speed approaching, flattening mechanism is moved immediately, the present invention also is defined in a cable wire stretching device is set on the lift system, make it when laying flattening mechanism, also to remain the cable wire in tension, thereby can make correspondingly fast lifting flattening mechanism of lift system.
Raise in order to prevent in formation process and to reduce dirt, another advantageous embodiments according to the present invention also advises a water spraying mechanism also is set on underframe, and it can be controlled, Gu this can spray or few water spray according to the situation of bulk cargo more, does not perhaps spray water.
From the embodiment that following contrast accompanying drawing is described and accompanying drawing itself can obtain further feature of the present invention, advantage and purpose, and all descriptions and/or graphic feature itself or any significant combination of these features all constitute content of the present invention.
The diagrammatic side view of bulk material leveling apparatus of the present invention has been shown in unique accompanying drawing.
Bulk material leveling apparatus 1 of the present invention has a framed structure of representing with label 2 on the whole, and this framed structure 2 has disposed the upper frame 3 of a level, and a lift system of representing with label 4 on the whole is housed on it.Be fixed with two guide rods 5 and 6 on the downside of upper frame 3, these two guide rods 5 and 6 are to be hinged on the position of representing with label 7 and 8 of upper frame 3. Guide rod 5 and 6 lower end are hinged on the whole on the flattening mechanism of representing with label 11, and hinge point is represented with label 9 and 10.Flattening mechanism 11 has smooth beam and that a underframe 12, for upper frame 3 is equipped with plough 13 to follow to sail direction F sees the smooth roller 14 that is contained in the back.In this embodiment, guide rod 5,6 is hinged on the underframe 12.The smooth beam 13 that also has plow-shape that links to each other with underframe 12, smooth roller then is rotatably supported on the underframe 12.
In the embodiment shown, lift system 4 is hoisting cranes 15, and it has a cable wire 16 that is connected with the underframe 12 of flattening mechanism 11 at least.
By the long and short dash line view of upper frame 3 tops as seen, can make upper frame 3 to top offset by lengthening framed structure 2.Framed structure 2 is positioned at the top of a loading and unloading track 17 and preferably is fixed on the there.In this case, the bulk cargo transport trolley that is made of the train railway carriage can pass framed structure 2 under tractive.Railway carriage 18,19 or by a corresponding tractive machine tractive or by a winch tractive.Railway carriage 18,19 is from a unshowned loading-unload station, in this loading-unload station is packed corresponding bulk cargo in railway carriage 18,19.
Bulk material leveling apparatus 1 is furnished with a non-contact type scanning device that is not shown specifically (or claim detector), and it has some different sweep units, below also will describe these sweep units in detail.On flattening mechanism 11, especially in underframe 12, be provided with first sweep unit 20,21 of scanning device, wherein sweep unit 20 is facing to travel direction F, and 21 of sweep units are along travel direction F.Each sweep unit in two sweep units 20,21 all has an independent sensor, or two side by side or the sensor of upper and lower settings, this point is not shown specifically.
The non-contact type scanning device also has one second sweep unit 22 in addition, and it is fixed on the upper frame 3 and directed downwards.Attachment point follows to be sailed direction and before the outer hinge-point 8 that is positioned at guide rod 6.A distance of these external framed structure 2 front and backs is provided with the 3rd sweep unit 23,24, and they point to the sidewall of the railway carriage that passes through from here.Situation with sweep unit 20,21 is the same, and sweep unit 22,23,24 also can have at least one sensor respectively, also can be two sensors perhaps, so that reduce the possibility that the single scanning parts produce fault thus.These sweep units are some ultrasonic tank under this routine situation, but fully also can adopt other non-contact type sweep unit.
Sweep unit 20 to 24 links to each other with hoisting crane 15 through a control mechanism, also will describe in detail below this control mechanism.Hoisting crane 15 can have two kinds of work speeds, and wherein a kind of is slower work speed, and another kind is high rising or falling speed.The value by the control mechanism correction that high rising or falling speed is measured according to sweep unit determines that make the bulk cargo transport trolley touch before the smooth beam, flattening mechanism 11 can move out from the leading flank of this transport trolley that is driving into.Like this, if require hoisting crane 15 that flattening mechanism is promoted 510 millimeters, the speed that railway carriage 18,19 travels is about 0.4 to 0.5 meter per second, and when two the spacing between the back front bulkhead of railway carriage was about 1 meter in succession, then described high rising or falling speed should be 0.255 meter per second at least.Consider corresponding safety factor, this speed should be about 0.373 meter per second.
The hoisting crane 15 that lifting loads is about 50KN (kN power) also is furnished with an overload protecting mechanism or overload cut off, when load reach rated load, nominal load 110% the time, this circuit is just with hoisting crane 15 disconnections.The live load of hoisting crane 15 is 32KN, this means that every cable wire will bear 16KN when adopting two cable wires 16.Under the situation of this overload protecting mechanism when flattening mechanism hovers on the jobbie on smooth position is useful, and this moment, the operator generally attempted with hoisting crane 15 " free tractive " flattening mechanism.For fear of impaired, therefore be provided with the overload cut off.
Except the overload cut off, hoisting crane 15 also is furnished with a cable wire stretching device or lax cable wire disconnects a protection and a hoisting crane relay switch (safety switch).It has also disposed in addition the transmission of four contacts limit switch, and these contacts are one and go up emergent limit switch and a following emergency switch, and one is gone up work limit switch and following work limit switch.
The lax protection mechanism of the cable wire that is not shown specifically remains at a kind of slack-free state with cable wire.Upper and lower emergent limit switch indicates the position, highest and lowest of flattening mechanism.
In part that the flattening mechanism shown in unique accompanying drawing is represented with long and short dash line top position, between by the diff-H that emergent limit switch is determined up and down, be the limit switch of working up and down corresponding to emergent limit switch on being provided with.
The height that starts railway carriage behind the operating switch can preliminary election, for example is 2.8 meters, 3.4 meters, 4.2 meters or 4.4 meters.Make flattening mechanism 11 startings go up operational terminal switch (benchmark operation) in view of the above, rise to desirable height afterwards.If arrive desired position at benchmark smooth beam in service, then height preliminary election process just is through with.Height preliminary election process can be interrupted by operating switch or safety switch.M/C is locking during during this period of time.
Can use manual control before the height preliminary election and afterwards, therefore the operator can handle on the optional position between the upper and lower operational terminal switch.In addition, flattening mechanism 11 links to each other with handler through aforementioned control mechanism.When handler was not activated in the regular hour, flattening mechanism will automatically be raised to work limit-switch point place always, enters stop position.Equally, when not being activated within a certain period of time, flattening mechanism itself can automatically not move to stop position yet.After flattening mechanism 11 has arrived stop position, disconnect hoisting crane 15 by last work limit switch.In order to eliminate the decline that parking period for example slides and makes flattening mechanism 11 produce inhuman hope owing to drg when longer, be provided with a unshowned mechanical latching.This locking both can manually have been carried out also can being realized by corresponding interlocking mechanism.Blocking is detected by an approximate initiator and is for example indicated by a red indicating light in a control cabin.
In order to carry out smooth work, at first to remove the mechanical latching of flattening mechanism, its result is measured by approximate initiator.Last work limit switch is noted the position of flattening mechanism, and control cabin sends the signal of " dead work " after approximate initiator discharges, and is for example indicated by a green indicating lamp.The operator pressed knob flattening mechanism was dropped to the position that requires this moment.Every kind of absolute altitude just can reach by the knob of every kind of absolute altitude of disposable startup.By means of approximate initiator, rotary angle transmitter or similar measuring mechanism are measured absolute altitude, and these measuring mechanisms continue to pass to control mechanism corresponding to each position of flattening mechanism under the desirable altitude record and with it.
If single sweep unit breaks down or because misoperation makes the safety measure on the hoisting crane fail to work, its result can cause the winch automatic cutout, perhaps sends the optoacoustic warning signal.
In addition, when the cable wire stretching device breaks down, can interrupt manual control, also can interrupt the height preselective control.Fault must be carried out the height preliminary election after eliminating again, perhaps reaches desired position with manual control.When the protection of overload cut off is broken down, must after eliminating fault, press one and reply knob, the same under the situation of the cable wire stretching device that coexists then, must carry out preliminary election again.If with manually or by the height preliminary election having started an emergency terminal switch, railway carriage travel direction at that time is just by locking so, and only could leave from this terminal switch under manual control this moment.Do not prepare if handler is made good berth, so just can not handle from supervisory control desk.By incoming line is transformed into field control from overhead control device is moved under the maintenance running state.Be provided with a shunt of operational terminal switch in addition.Under this mode of operation, the operator can cross the operational terminal switch, checks the emergency terminal switch thus.If arrive the emergency terminal switch, then the continuation operation along equidirectional is subjected to locking, and this is to be implemented by control mechanism.If train sails in bulk material leveling apparatus along the opposite way round, then flattening device will take the operational terminal switch position to with being compelled to.When four standing heights are not all set up, on travel direction situation same as described above can take place.If be to carry out smooth work at this moment with manual control, and smooth beam apart from the spacing of railway carriage end less than 1 meter, so smooth beam too by band to operational terminal switch place.
Can confirm in a word, the invention provides a kind of possibility that can guarantee material spreading cone heap flattening device reliable operation, wherein prevent railway carriage contact flattening mechanism.This device not only can be manually, semiautomatic control, and can full automatic control, and this device can be applied to any place that will mobile bulk cargo.
