Description
Technical field
The present invention relates to a kind of by the method for first claim toter as described in the preamble, processing lifting crane track and the Fabricating machinery of grinding lifting crane track.
The present invention can be applicable to all places that have toter lifting crane track there, the lifting crane track has out-of-flat and gradient behind certain running life, they no longer allow lifting trolley at high speed nothing to find fault with, be without rebuke and safe operation, thereby need to change the lifting crane track or with its reparation.The present invention is specially adapted to the hoisting crane of the lifting trolley of fast running, and these lifting trolleys are carried big load, for example freight container.
Background technology
Be used for the toter of freight container by the known a kind of this type of DE 43 07 254 A1, wherein on its crane runway, move a plurality of hoisting device.
Crane runway on hoisting crane has the shape of rectangle usually, so that make trolley have the blade wheel of straight rolling surface to move on crane runway equally.In container handling crane, the length of lifting crane track often reaches 100 meters, and trolley moves with high speed on its track.The rail of lifting crane track welds or clamps mutually and with hoisting crane, thereby produces out-of-flat or joint.Especially the transition region between hoisting crane water side and quay side part, because be difficult to make the lifting crane track of quay side and water side to be located on the same height, so after the operation of long period, formation step or " erosion " in this transition region.Because track and trolley blade wheel have flat surface, move at the track middle part all the time with its blade wheel so must guarantee trolley.Therefore in hoisting crane the crane runway lateral vertical establish side wheel or guide wheel.They guarantee that flat blade wheel rolls along its rolling surface in central authorities.Through behind certain work-hours, especially under the situation of the trolley of running at high speed that transports big load such as freight container, cause crane runway that out-of-flat is arranged, because braking and accelerator, the snap close place between hoisting crane water side and quay side part exist welding or rail joint, this out-of-flat causes flat raceway surface along track different height to be arranged, thereby causes vibration of lifting trolley or swing.Transverse to track, because side wheel rolling especially on the outer surface forms gradient in a side of track, wherein, rolling surface itself has a protuberantia in the middle, and this protuberantia is along the total length uneven distribution of crane runway, and blade wheel has a depression in the middle.
This result who brings based on the distortion of load behind certain work-hours is, the rolling surface that is used for blade wheel no longer can use in this way, under high speed, can cause blade wheel damage, out of roundness or blade wheel chatter, must be prophylactically repair face but also repair wheel not only.This just makes want of repair processing, current regulation with flat blade wheel replace this blade wheel and rolling surface be ground to again flat, so new blade wheel can be mobile on the flat surface through correcting.This need consume lot of materials and work-hours, thereby makes corresponding cargo transfer equipment owing to repairing work forms long standing time.
Repair hoisting crane and trolley track by DD 297 134 A5 are known by riveting over or strengthening the worn-down track, wherein putting a new track and old therewith captive joint on the worn-down old track along the total length of crane runway.In this example, in order to settle new-track to need big fitting work amount.The blade wheel of worn-down trolley must be repaired equally, to make it to have equally the flat shape of new-track.In order to guarantee that new-track is flat along its total length and with respect to parallel with it track, especially when trolley answers at high speed to travel, needs the grinding track.This method is that it often can not optionally be implemented except big fitting work amount and another shortcoming the material consumption.If adopt side wheel to make stableization of trolley, then only have limited use possibility for this method.
By the known a kind of method of repairing worn-down trolley track of DD 300 879 A7, this method regulation, excise along fixable height level in the zone of its relevant rail bed by cutter on worn-down track top, and plane earth is settled a track of replacing on the rail bed that stays, and captives joint with the supporting edge of a wing of trolley track at the bottom of its track.This method that is used to process the trolley track must think that also consumptive material is many and work capacity is big, and reparation according to said method also often can not optionally be implemented.
Therefore those are in-problem with crane track by darker horizontal component excision and the method and apparatus of creating a new planar tracks thus, because must the very thick material layer of excision, this can not have no difficulty when adopting traditional equipment for grinding.
By DE-US 24 20 631 known a kind of devices that are used to clean hoisting crane supporting and orbit, wherein stipulate to remove because the magnetizable part that severe wear forms in orbit by brush, so-called oxide skin, and be collected in the container below the track by magnetization.This equipment is not suitable for being engaged in a large amount of surface treatments certainly on crane track, be this situation when the trolley track weares and teares for example.
Introduced a kind of orbital sander and be used for grinding off irregularity on the rail surface of track in EP 0 648 895 A2, the grinding unit of polishing lathe can be with respect to the rail adjustment, and wherein, this grinding unit has had the shape of the rail of the grinding wanted.This orbital sander can be rolled on rail by the wheel edge wheel, and only is only applicable to the rail on the railroad track of standard.These tracks have the load on very high the acted on Fabricating machinery, and the grinding of rail is undertaken by abrasive belt gringding mechanism, and track is with the very long distance of this grinding mechanism grinding.For this kind equipment of hoisting crane crane runway in big height work is inapplicable.
Summary of the invention
Therefore the objective of the invention is to find some possibilities, need not to repair widely the hoisting crane crane runway, with the use less material, eliminate many disadvantages known on the hoisting crane crane runway economically in the short period of time.
This purpose is by by the toter of first described feature of claim characteristic, reach by the described Fabricating machinery that is used to process the method for hoisting crane crane runway and is used for grinding hoisting crane crane runway of first, the 6th and the 7th claim.
Dependent claims has illustrated the design that the present invention is favourable.
Stipulated a kind of toter by the solution of the present invention, the blade wheel of its load car has protruding rolling surface, and the lifting crane track has, a shock-free middle part flat along the track total length, and it is in identical height level with the middle part of adjacent orbit.This track has the part of oblique deascension in the both sides, middle part, wherein the side at track has a chamfering (phase).By along track total length this flat and shock-free middle part, even guarantee also can not cause vibration under the situation of the trolley of fast running, otherwise because vibration can produce track when high capacity be out of shape rapidly.Because the middle part of two tracks is on the identical height level,, thereby makes sidepiece or guide wheel only produce the little effect of rolling in orbit and do not forming any protuberantia in long length of life so side force is little.By having a chamfering, prevented to form protuberantia in long length of life in residing that side of the side wheel of track.In addition, track has the part of oblique deascension in the both sides at middle part, impels trolley to be designed to protruding blade wheel homing guidance, and thereby make the guide wheel load of side less so that do not produce side force fully.
Advantageously chamfering is made 45.
Advantageously the ratio of lateral parts and pars intermedia branch is about 1: 3 in addition.
Two sidepieces should be about 5 ° with respect to the angle of middle part oblique deascension.
In order also to compensate the roll off of track side surfaces by chamfering, require this chamfering to be in that side that is provided with trolley side direction roller or guide wheel of track.
Adopt this track and in conjunction with being designed to protruding blade wheel, might make the blade wheel of trolley and track under high capacity and high-speed situation, only need low maintenance cost to move in long length of life.
The present invention can be used in immediately protruding wheel being contained on the hoisting crane together with illustrated trolley track.But also advantageously process worn-down trolley track, make it to have the shape of being advised.The blade wheel of trolley has protruding shape after certain useful life.As for track, then must at first determine along the vertical degree that changes of track by measuring equipment.Must determine what variation track arranged side by side in height has each other in addition.Also must determine the intensity of variation of trolley blade wheel in addition.Then, the number of degrees that are used for chamfering of grinding track side surfaces in first grinding process are pressed the sidepiece of the even oblique deascension of shape grinding of blade wheel in second grinding process, and the last flat middle part of grinding.Guarantee that thus protruding blade wheel does not have impact and the operation of friction ground, meanwhile side wheel has less thrust and realizes blade wheel auto-centering in orbit.A grinding process can comprise the amount of the repeatedly fine grinding of rail section to regulation.
Be used for grinding lifting crane track by Fabricating machinery of the present invention, the characteristics of this equipment are that it at one end has the anchor fitting of a trolley, Fabricating machinery can be captiveed joint with trolley by this anchor fitting.In addition, Fabricating machinery also has the grinding attachment of a stationkeeping in its forward region, can go out identical height in the grinding of track top along the total length of track by it, and also can be provided with 45 ° of chamferings of that side grinding of trolley side wheel by it.Fabricating machinery has adjustable grinding wheel arbor in rear area, but by the part of its grinding track oblique deascension, the part of oblique deascension has identical angle along track length, and this angle can be 5 °.This orbital sander is designed for repairs the existing old crane runway that is worn by use; That is to say that grinding off surface (rolling surface) goes up damaged local or smooth again impaired orbital plane.In weight-lifting equipment with high acceleration and braking potential especially in the trolley of fast operation, As time goes on, in orbit, especially before welded joint and after the zone in, and at the orbit gap place, for example spread out from the cantilever to the bridge in the container handling crane transition region of frame produces localized wear's (erosion).The generation of this erosion is owing to scolder different superficial hardnesss is arranged at track welded joint place track woof.Identical consequence appears in having the new track of different hardness equally.
The principle of work of polishing lathe be based upon this machine is installed on the existing hoisting crane crane and with trolley by on the basis of grinding for best stroke reciprocating.When surfacing, the electronic regulator of electrical motor is born the task and thereby the control quantity of material that will excise of control grinding machine head feeding.If polishing lathe moves towards a peak face in orbit, then need bigger electrical motor moment.The information of being sent by electronic machine arrives axial adjustment mechanism and provides signal " emery wheel acceleration ", diminishes again until electrical motor moment.Therefore the peak face is easy to remove.Repeat same effect in the next course of processing or the time, so the peak face is removed piecemeal next time through this peak face.That is to say in fact not reach absolute flat surface, but by repeating through removing the peak face piecemeal.
Inhomogeneous in order to prevent emery wheel load when out-of-flat is arranged, emery wheel is located between the bogie wheel that rigidity is installed in couples.Therefore when running into depression, can guarantee to move at the highest surface region all the time.Guide wheel on horizontal shaft guarantees to guide along track side surfaces to locating at each bogie wheel or each bogie wheel.
Enter in the solid material of rolling surface for fear of polishing lathe when grinding skin (rolling surface), begin with a roof shape bevelled grinding machine head.Track is at first in the grinding obliquely of outside face roof shape.Because there are two grinding machine heads, so be easy to adjust different angles.After finishing by grinding process of this location, first reduces this angle and with a less oblique angle grinding skin.Make this angle become more and more littler by repeatedly changing angle, until the horizontal location that reaches two grinding machine heads.Slightly be polygonal structure if present surface has, be expressed as a radius from macroscopic view.Then at this moment remove the gable on this radius or two inclined-planes by further grinding, and make one by the repeatedly grinding under this location and account for about 70 to 80% the surface of track width by horizontal location.For the track that a radius is arranged, this radius of ground grinding of can having no problem.
When track side surfaces is impaired, can process this side by the additional grinding machine head that is contained in the polishing lathe front portion that exists.This grinding machine head or install by absolute vertical position, thus form one with the rectangular surface of rolling surface.If wish, also can be adjusted into a little angle.
If track has the trend that slightly is lonely shape in birds-eye view, then at first process exist extreme, that is maximum arc.Can weaken extreme arc thus and change, and eliminate less inaccuracy.
Can be by the damage that wheel rim or guide wheel cause in the side, top by additional grinding tool longitudinal plane ground grinding (dissipation).
By the electrical motor moment of control polishing lathe, avoid the excessive pressure in top to cause the trackwork face to heat terrifically and organize variation.
When carrying out the rail joint welding in many places when polishing lathe also can be applicable to more the section of switching tracks in addition or in track fracture back.In this case can be after welding processing smooth welded joint, and in a course of processing, implement the flat surface grinding of whole rail.
By selecting different grinding machine heads can process all general-duty rail materials, comprise hardened steel.The installation of polishing lathe on the lifting trolley can be undertaken by a hinged base plate that is placed in the polishing lathe end.Must weld or load onto and lifting crane bonded assembly towing plate when needed for this reason.
Advantageously the setting range at grinding angle is horizontal 0-15 ° and vertical 70-90 °.
