Specific embodiment
Embodiments of the present invention are illustrated by particular specific embodiment below, those skilled in the art can be taken off by this specification
The content of dew understands other advantages and effect of the present invention easily.
Refer to Fig. 1.It should be clear that structure, ratio, size depicted in this specification institute accompanying drawings etc., only to coordinate
Content disclosed in bright book, so that those skilled in the art understands and reads, is not limited to enforceable restriction of the invention
Condition, therefore do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size, in not shadow
Ring under present invention effect that can be generated and the purpose that can be reached, still all should fall obtain and can contain in disclosed technology contents
In the range of lid.Meanwhile, in this specification it is cited as " on ", D score, "left", "right", " centre " and
The term of " one " etc., is merely convenient to understanding for narration, and is not used to limit enforceable scope of the invention, its relativeness
Be altered or modified, under without essence change technology contents, when being also considered as enforceable category of the invention.
In prior art, when the pivoting support of stacker-reclaimer is changed, need the armamentarium in cycle portion and top complete jacking
Afterwards, pivoting support could be removed, but directly synchronizes jacking, it is found that stacker-reclaimer body occurs skew, cause bolt cannot
Fastening, needs prolonged adjustment bolt be installed in place stacker-reclaimer pivoting support.Based on work efficiency is improved, improve and install
The purpose of precision and safety coefficient, the present invention provide a kind of replacing options of stacker-reclaimer pivoting support, and stacker-reclaimer includes machine
Seat, the cycle portion on support and the pivoting support between support and cycle portion, it is refering to shown in Fig. 1, of the invention
The replacing options of pivoting support are comprised the following steps：
Preparation of construction：Stacker-reclaimer fixation in place, before construction, stacker-reclaimer should rest in airplane parking area position, in no airplane parking area
In the case of as far as possible select horizontal rail absolute altitude preferably (± 2mm) and place open area.The machinery of locking stacker-reclaimer running gear
In the case of band-type brake, no band-type brake, with wedge pad below the wheel and and track spot welding.
The anglec of rotation in Reasonable adjustment cycle portion, to facilitate jacking and facilitate the turnover of plane bearing to be defined., adjustment reclaimer cantilever
Rise lift angle, position of the pitching hydraulic cylinder cavity pressure reading as 1-3MPa with below cantilever, now rise lift angle be generally level side
To -5 ° of -0 ° of ° of positions.
Tripartite confirms to have a power failure listed, after hydraulic means is closed, removes auxiliary device, auxiliary device include rotation motor,
Plane bearing cover, lubricating oil pipe, the steel construction interfered, electrical equipment etc..
Carry out the installation of jacking location structure and Multi-point synchronization jacking mechanism.Jacking detent mechanism be used for make jacking accuracy guarantee ±
Within 1mm, mainly it is made up of the soleplate, top nut, lower nut that arrange on positioning screw, positioning screw.At least three is fixed
Position screw rod is arranged at pivoting support periphery along pivoting support axial direction and around pivoting support centrosymmetry, and each positioning screw is provided with base
The top nut at plinth plate and correspondence soleplate two ends, lower nut, soleplate are fixedly connected on the outside of cycle portion.Soleplate sometimes for
Full weld is reinforced, prevents from being torn because of biasing force.
The synchronization of jacking up hydraulic cylinder that Multi-point synchronization jacking mechanism is arranged at by least three between cycle portion and support is constituted.It is synchronous to push up
Rise hydraulic cylinder to be typically mounted at below the jacking bracket in cycle portion.In the case of without jacking bracket, with the principle of symmetrical balance around
Pivoting support centrosymmetry is arranged.
Crane carries out first dynamic leveling weighing apparatus operation.In order to coordinate jacking, equilibrium stage is integrally reached, reduce skew during jacking
Amount.Slowly sling by crane the free end of cantilever, until the cavity pressure of pitching hydraulic cylinder is adjusted to by 1-3MPa before
0-1MPa。
The jacking of cycle portion.After removing the fixing bolt of pivoting support, start all synchronization of jacking up hydraulic cylinders and jacking implemented to cycle portion,
The jacking of cycle portion adds 50-100mm for the thickness of pivoting support to preset displacement, specifically with new pivoting support smoothly can penetrate as
It is accurate.Top nut on jacking prelocalization screw rod every time moves up 20mm, and per jacking 10mm, lifting operation stops, hanging in cycle portion
Car carries out a dynamic leveling weighing apparatus operation, is repeated until the jacking of cycle portion is to preset displacement.
As a further improvement on the present invention, all synchronization of jacking up hydraulic cylinders are controlled by PLC synchronous jacking systems, and PLC is same
At least provided with display module, monitoring modular, performing module, alarm module in step system.Monitoring module monitors performing module each
The top lifting height of synchronous point is simultaneously shown in display module.Constitute the top that each synchronous point is shown on the computer or display of display module
Rise, trueness error is typically within the scope of 0.5mm.When the error of each point is more than 0.5mm, alarm module is reported to the police,
So as to improve security performance during operation.Each Jacking point needs for being equipped with survey crew simultaneously, carries out dual safety guarantee.
Pivoting support is changed.The turnover side of pivoting support arranges two support beams (channel-section steel or other high strength steels) and makees interim flat
Track is moved, the setting principle of track is can not to interfere with jacking hydraulic cylinder, and facilitates plane bearing to move.Pivoting support is adopted
The mode for removing is coordinated to remove, install with chain block.Pivoting support is moved to and slip on translation track, skids off, pivoting support
After replacing, translation track is withdrawn from.
New pivoting support needs to clean up the flange face in cycle portion and pedestal before installing, if any salient point, grinding process to be carried out.
After pivoting support is installed, in the falling operation in cycle portion, the lower nut for being fallen after rise on prelocalization screw rod every time moves down 20mm, revolves
The portion of returning often declines 10mm, falls operation after rise and stops, and crane carries out a dynamic leveling weighing apparatus operation, is repeated until cycle portion falls after rise
To original position.
Pivoting support change finish after, related rotation motor, plane bearing cover, lubricating oil pipe, interfere steel construction, electrically set
Standby to be recovered, after equipment runs well 48 hours, needing to shut down carries out secondary fastening the bolt of plane bearing.
In sum, the present invention using dynamic leveling weigh operation and jacking location structure coordinate Multi-point synchronization jacking can quickly, height
Effect changes the pivoting support of stacker-reclaimer, so as to significantly shorten the activity duration, improves construction efficiency, reduces labor intensity, and show
The installation accuracy for lifting pivoting support is write, security risk is reduced.So, the present invention effectively overcomes of the prior art a variety of
Shortcoming and have high industrial utilization.
The principle and its effect of above-described embodiment only illustrative present invention, it is of the invention not for limiting.It is any to be familiar with this skill
The personage of art all can carry out modifications and changes to above-described embodiment under the spirit and the scope without prejudice to the present invention.Therefore, such as
Those of ordinary skill in the art completed under without departing from disclosed spirit and technological thought all etc.
Effect modifications and changes, should be covered by the claim of the present invention.
