Description
Technical field
A kind of improvement for the grab bucket mechanism structure fished for the present invention relates to level.
Background technology
Aluminum electrolysis multifunctional crane is important auxiliary equipment in Aluminum Electrolysis Production, for aiding in large-sized prebaked aluminium
Electrolytic cell production operation, with handling, blanking, changes the functions such as anode, crust breaking, scarfing cinder.
, it is necessary to be transported anode scrap using the slag cleaning device of aluminum electrolysis multifunctional crane during aluminum electrolysis cell anode replacement
The residues such as the electrolyte caking in anode scrap hole after walking are cleaned out, and then could arrange new anode, and the presence of residue will be tight
Ghost image rings the progress of electrolytic cell Inner electrolysis reaction.The slag cleaning device of present wide variety of aluminum electrolysis multifunctional crane, which is used, grabs
Struggle against mechanism, and grab bucket mechanism is by being arranged symmetrically and being constituted around two scraper bowls of respective rotating shaft rotating open-close；Due to scraper bowl around
Fixed hinge rotating open-close, the movement locus at scraper bowl tip is a camber line.When grab bucket fishes for residue in anode scrap hole, scraper bowl
The scope fished for is in sector region, and the blind of residue is fished in the region between the sector region and cathode surface for slag cleaning device
Area, therefore a part of residue is necessarily left in anode scrap hole.In order to which the residue left is cleaned out, it is necessary to which surfaceman makes
Continued to clear up with simple tool, be the molten electrolyte of high temperature in being cheated due to anode scrap, the cleaning residue working environment of workman is severe,
And with danger.
Due to above mentioned problem, the grab mechanisms that some levels are fished for also are occurred in that on the market, and these horizontal grab mechanisms are equal
The running orbit of grab bucket is detected using electric elements, the range of grab bucket is then gone out according to trajectory calculation, and controls grab bucket suitable
When carry out elevating movement, so as to reach the purpose for fishing for grab bucket level.The grab bucket that this utilization electric elements are controlled
Although device can functionally reach requirement, because in aluminium electrolysis shop, environment is more severe, electric elements are used
Life-span can be severely impacted, therefore, the phenomenon for electric elements damage often occur, increase maintenance capacity, improve and be produced into
This.
The content of the invention
The present invention, there is provided a kind of fault rate is low, realizes what level was fished for aiming above mentioned problem using pure mechanic structure
Grab bucket mechanism.
In order to realize the above-mentioned purpose of the present invention, the present invention is adopted the following technical scheme that, the present invention includes by control cage, moved
Moving frame, and control cage and movable stand upper and lower ends the parallelogram four-bar linkage structure that is constituted of first connecting rod, its feature
It is：It is provided with movable stand in cylinder, control cage and is provided with sketch plate, one end of sketch plate and the piston rod of the cylinder is cut with scissors
Connect；The other end of sketch plate, which is hinged, is provided with second connecting rod；Lower end on the movable stand corresponding to sketch plate is provided with support
It is hinged between the lower end of arm, support arm and sketch plate and is provided with compensation link；The sketch plate and second connecting rod pin joint, abnormity
The pin joint of plate and cylinder piston rod, and the line of the pin joint of sketch plate and compensation link is in the middle part of triangle, sketch plate
It is connected by first rotating shaft with control cage；The lower end of the second connecting rod, which is hinged, is provided with two third connecting rods, two third connecting rods
The end that bucket connecting rod is opened in lower end with two respectively is hinged, and two open second turn of the other end of bucket connecting rod respectively with control cage two bottom sides
Axle is connected；Two lower sides for opening bucket connecting rod are provided with mutual corresponding scraper bowl.
Beneficial effects of the present invention：In the course of work of the present invention, compensation link follows sketch plate to rotate, make first rotating shaft,
Control cage and scraper bowl produce reverse vertical displacement relative to movable stand, and the displacement will compensate scraper bowl tip and be produced during opening and closing
Raw vertical displacement.By the compound motion of each component in whole mechanism, make the final resultant motion track in scraper bowl tip approximate
Ground is in a horizontal linear.Therefore, the present invention is in scale removal process, and scraper bowl tip can be kept away further close to cathode surface
Exempt to fish for the presence of blind area, substantially improved cleaning effect, and improved production efficiency, reduce the input of manpower
In addition, the present invention is pure mechanic structure, and compared with the method controlled in the prior art by electric elements, the present invention
Adverse circumstances are suitable for, are hardly damaged, maintenance is also convenient for.
