Description
Technical field
The utility model belongs to Belt Conveying machine bearing maintenance tool technical field, especially a kind of belt pulley bearing replacing
Tool.
Background technique
Currently, belt conveyor is used widely in mineral processing production transportational process, during production run often
It will appear belt pulley bearing damage.Since belt pulley bearing is hot charging, fit-up gap is tight, and scene is extremely difficult when dismounting, mostly
Number is separated bearing bracket stand using the methods of gas cutting, after bearing grain is plucked out one by one, then bearing block is removed, is then used gas again
Weldering slices off bearing internal external sleeve from axis and bearing block, completes dismantling, sometimes due to the factors such as site space is narrow, fire prevention, need
Integral replacing driving drum is wanted to solve the problems, such as bearing damage.It occur the problem that 1 since in this way, often will appear scald,
Injure the accident of maintenance worker by a crashing object;2, it marches into the arena and can damage due to using the method for gas cutting to remove bearing internal external sleeve from axis and bearing block
Axis or bearing block lower service life, increase spare parts consumption, increase cost consumption；3, since the method for using gas cutting (can generate
Axis and bearing block overheat can not return dress) or integral replacing great wheel, according to too long at the repair time, especially online emergency repair time can be longer
(generally requiring time 8-9 hour), directly affects production run, and 4, decompose on usually ground, due to overlong time labor intensity
Increase, increase manual labor, can also cause safety accident, 5, bearing dress can be made not since heating time is short when returning dress sometimes
In place, it is tapped with sledgehammer, causes bearing damage, increase cost consumption.Therefore, the decomposition assembly for solving belt pulley bearing is asked
Topic, perplexs always upkeep operation, because driving drum bearing is hot charging, there are also site environment problem, leads to not the scene of carrying out
Driving wheel bearing is replaced, and influences repair schedule, so as to cause the stable operation for influencing production.It is particularly significant.
Summary of the invention
The purpose of the utility model is to provide a kind of belt pulley bearing changing tools, solve bearing and replace decomposition assembly online
Problem, while the repair time is shortened, it keeps the safety in production, improves production efficiency, reduce consumption, save the cost.
The utility model this be achieved.
A kind of belt pulley bearing changing tool of the utility model, which is characterized in that including lift truck, top plate has spiral shell
The fixed disk and jack assembly of keyhole, the jack assembly are arranged on lift truck, and the jack assembly is by propping up
Hold seat, the jack that is placed on pedestal, two both ends for being arranged in jack front outsides have the semicircular arc fixture of flange
It is formed.
The fulcrum bearing is connect by lower plate, the interior support plate connecting with lower plate one end and with the lower plate other end
External support plate is formed, and two bolts hole up and down are provided on outer support plate, is equipped with bolt hole on the top of interior support plate, described
Two with flange semicircular arc fixture upper flanges be fixedly connected by screw with the upper bolt hole of external support plate, two
The lower end flanges of semicircular arc fixture 4 are fixedly connected with the top of interior support plate equipped with bolt hole by screw.
The lift truck includes the chassis of vehicle body with wheel, and the double leval jib elevating mechanism and setting being arranged on the car body exist
The workbench on double leval jib elevating mechanism top, is additionally provided with idler wheel on the table.
With the round top plate of convex rotary table centered on the top plate.
The utility model has the advantages that: it efficiently solves the problems, such as that belt pulley bearing replaces decomposition online, makes belt pulley
Bearing replacing is more convenient, time saving and energy saving, avoids having prevented belt pulley bearing more due to replacing belt pulley bearing overlong time
It changes, security risk present in disassembly process, provides premise for steady production index；Meanwhile guaranteeing assembly precision, shorten
Assembly time.
