Description
Technical field
The present invention relates to pallet simulation test, more particularly to the assembly simulation experiment dress of a kind of pallet fire grate bar
It sets.Using designed pallet fire grate bar assembly simulation experimental rig, burning under fire grate bar normal temperature condition can be simulated
Assembly, operating status on knot machine trolley.The present invention can be used in the trial-production experiment of fire grate bar product, without in large-type sinterer
It is tested on trolley, reduces experimentation cost and empirical risk.
Background technology
Fire grate bar is the key that one of sintering pallet vulnerable part.There is the fire grate being much arranged in order on sintering pallet
Item, the boss between adjacent fire grate bar are connected, and gap is formed between fire grate bar, and the fire grate bar of permutation and combination is former for carrying sintering
Material, exhausting, sintering.When sintering, the temperature of short time (about 15 min) interior sinter is up to 1100 DEG C or so, the surface of fire grate bar
Temperature is cooled to 100-300 DEG C or so again up to 800-950 DEG C, with the operation of trolley, in high-temperature sintering process, fire grate bar
Sintered ore materials gravity should be born, bears the high speed impact abrasion of powder, gas two phase flow again, when trolley walking is with batch turning,
Fire grate bar still suffers from strenuous vibration, and operating mode is very severe.
The large-type sinterer of traditional produced on-site is belt or circular travelling sintering machine.As shown in attached drawing 1,2, pallet
Structure include trolley piece frame 1, roller 2, baffle 3, fire grate bar 4 etc., furnace grid 4 be on sintering pallet it is main easily
Part is damaged, is generally cast with heat-resisting, antifriction alloy.The close adjacent fire grate of number row is generally arranged in the bottom of each sintering pallet
Item is often arranged according to a fire grate bar more than sintering pallet width design tens or even 100, is had the gap between each fire grate bar side
For sintering feed negative pressure down draft sintering.Multiple pallet sequential arrangements, run on the rail set of sintering machine, worked
Cheng Shi：Continuous rotation is done by the head star wheel 5 of actuator drives, trolley is lifted into top by lower tracks through head bend
Horizontal rail, star wheel toothed plate continue to press on trolley card wheel, since star-wheel ceaselessly rotates, continuously push and next are lifted to water
The trolley card wheel in plate rail road, the car team that thus makes entirely to appear on the stage are moved to sintering machine tail, when trolley reaches tail, in tail portion star
Sinter is unloaded under the control of wheel tooth plate and tail portion bend, returns to lower horizontal rails, carries out working cycles next time.
If traditional produced on-site is done scaled down with pallet makes laboratory simulation equipment, inevitably
Fire grate bar size is reduced, this can not provide practical directive significance to fire grate bar assembly, the middle simulated test experiment newly developed, use
Value is little, and the fire grate bar of scaled down version prepares extremely difficult, and the pallet structure of scaled down version is also still complicated.
Existing furnace grid on sintering pallet using there are the problem of include：When the fracture of some furnace grid, part
When falling off, local material leakage can be caused；After furnace grid fracture, local shedding, remainder can loosen, when trolley is run to sintering machine
When annular bend turns to, the fire grate bar of loosening can be slided, be tilted, and caused adjacent several furnace grid avalanche types to loosen, be scattered, be sintered
Board car bottom hollow out, it is necessary to shut down, supplement fire grate bar again, seriously affect sintering machine normal operation.
Fire grate bar that is traditional or newly developing is fit directly on large scale sintering machine trolley and runs, fracture, defect mistake
Cheng Wufa is observed, as long as also, fracture occurs, defect, is integrally scattered, pallet bottom hollow out, sintering machine can only be shut down or empty mistake,
Seriously affect production.
Have no that document introduces pallet fire grate bar assembling test simulator, fire grate bar assembly simulation test method at present
Open report.The pallet of scaled down version is complicated, such as needs simulation actual field production to be run with pallet, also wants
Distributing planetary gear, transmission device, structure is more complicated, this is that the art has no that pallet fire grate bar assembly simulation tries
Experiment device and major reason.
Invention content
The object of the present invention is to provide a kind of grid section assembly simulation experimental rigs of pallet stove, mainly solve not having at present
There is the technical issues of assembly of simulation sintering machine fire grate bar and operating test device.The present invention simulate fire grate bar normal temperature condition under

Seat or setting axis hole.The frame is by angle steel or channel steel or steel plate and rectangular frame made of connecing, with fire grate strip
To match, the center installation axle at both ends, axis is matched with the bearing block on column top or axis hole, rectangular frame both ends setting snap-gauge,
Fastener is used for stationary furnace grid section, and the structure of rectangular frame both sides is capable of the upper lower cantalever of clip fire grate bar, when frame rotates
When, the upper lower cantalever of fire grate bar can be suspended on frame.The axis of the rotating disk and frame one end, which is formed, to be sequentially connected, in addition
Power or manual rotation are set, drives rectangular frame along axis Arbitrary Rotation, it is practical by being simulated around the spinning movement of axis original position
Tangent line rotation.
The method have the benefit that：Compared with the prior art, it is an advantage of the invention that：With practical large-type sinterer
Trolley structure is entirely different, but can simulate fire grate bar operating condition on large scale sintering machine trolley, is not necessarily to roller, baffle and planet
Gear and running track need not also make fire grate bar group around the cyclic annular fortune of the rotation of sintering machine head end planetary gear tangent line and running track
Turn, rotated by simulating actual tangent line around the spinning movement of axis original position, is operated, simplified instead of planetary circular orbit using rotation
The structure of experimental rig.With simple frame and fixing chuck plate, operated instead of planetary circular orbit using rotation, you can real
Assembly, the operation simulation of existing fire grate bar, analogy method is flexible, and the trial-production for fire grate bar product is tested, without in large scale sintering
It is tested on machine trolley, reduces experimentation cost and risk.It can realize the operating mode that is impacted of simulation fire grate bar, observe and assemble
The operating condition of one group of fire grate bar provides foundation for the development of fire grate bar.The present invention, which solves the art, can not observe stove
Grid section runs on large scale sintering machine trolley, is broken, the research puzzle of defect process.
