Abstract
The invention discloses a kind of replacing options of thickener center steering bearing, and after thickener is stopped, jack is arranged in the concentration basin below thickener, jack center steering bearing by jack, then will replace after center steering bearing cutting.Construction period of the present invention about 10 days, replacement cost was low.
Description
Technical field
The present invention relates to thickener field, the replacing options of specifically a kind of thickener center steering bearing.
Background technique
Thickener mainly undertakes the function of Tailings Slurry dehydration, processing capacity 250-370t/h, and groove body internal diameter is 60m, should
Equipment uses peripheral drive, drags large and small climbing frame by center steering bearing and rotates, achievees the purpose that bottom tailings discharge.
Axial load, radial load and tilting moment are carried in center steering bearing operation.After long-play, it can go out
The problems such as existing Internal and external cycle dislocation, local gap become larger, and internal ball loses circle, deformation, leads to equipment fault.
Original repair method process are as follows: 1, disconnect into pipe road and gantry；2, feeding cylinder is removed；3, remove centre mount and in
Heart cylinder；4, consolidation shed pivoting support；5, it is installed by dismounting sequence.Existing repair method construction period about 45 days, needs
More machine-team cranes are employed, it is costly.
The object of the present invention is to provide the replacing options that a kind of thickener center steering supports for summary of the invention, existing to solve
The problem of time-consuming with the presence of thickener center steering bearing repair method.
In order to achieve the above object, the technical scheme adopted by the invention is as follows:
A kind of replacing options of thickener center steering bearing, it is characterised in that: the following steps are included:
(1), thickener is stopped, and make the gear frame of thickener stop to at the position 90o, be readily transported into mine gantry material and
Personnel enter and leave, and close general supply after parking；
(2), ore pulp in the concentration basin below thickener is drained, concentration basin bottom of pond sludge is rinsed well and by the underflow of concentration basin
Nozzle closing falls into pipeline to prevent sundries when construction；
(3), the trolley in the bearing of thickener center steering is removed, when dismounting protects slip, sliding block, insulator, and slices off
The support angle steel of trolley, while the slideway in trolley is translated up into 200mm and is welded and fixed；
(4), the electronic dry oil pump oiling oil pipe in thickener is removed, package is at oiling oil connection to guarantee in oil pipe not into miscellaneous
Object；
(5), multiple suitable positions are looked for place hydraulic jack on concentration basin ground, bottom is laid with special stand, pedestal and bracket
Support welds, and channel steel pair can be used according to field condition with the center rake structure frame that jack withstands center steering support connection
Center rake structure frame is reinforced, then lifting jack, makes center steering bearing not by external force；
(6), by central tube away from being cut open at pedestal 350mm, with jack will into mine gantry, feeding cylinder and centre mount integral raising,
Separate central tube；
(7), the bolt of fixing bearing inner sleeve, housing is all removed；
(8), bearing is removed, is hauled out with jack.
The present invention separates central tube first, and is raised about 300mm；Center steering bearing is examined from partition place dismounting
It repairs.This method construction period about 10 days, replacement cost was low.
Specific embodiment
A kind of replacing options of thickener center steering bearing, comprising the following steps:
(1), thickener is stopped, and make the gear frame of thickener stop to at the position 90o, be readily transported into mine gantry material and
Personnel enter and leave, and close general supply after parking；
(2), ore pulp in the concentration basin below thickener is drained, concentration basin bottom of pond sludge is rinsed well and by the underflow of concentration basin
Nozzle closing falls into pipeline to prevent sundries when construction；
(3), the trolley in the bearing of thickener center steering is removed, when dismounting protects slip, sliding block, insulator, and slices off
The support angle steel of trolley, while slideway translates up 200mm and is welded and fixed；
(4), the electronic dry oil pump oiling oil pipe in thickener is removed, package is at oiling oil connection to guarantee in oil pipe not into miscellaneous
Object；
(5), multiple suitable positions are looked for place hydraulic jack on concentration basin ground, bottom is laid with special stand, pedestal and bracket
Support welds, and channel steel pair can be used according to field condition with the center rake structure frame that jack withstands center steering support connection
Center rake structure frame is reinforced, then lifting jack, makes center steering bearing not by external force；
(6), by central tube away from being cut open at pedestal 350mm, with jack will into mine gantry, feeding cylinder and centre mount integral raising,
Central tube is separated, is detachable center steering bearing after separation.
