Description

A kind of devices and methods therefor of installation or removal slide shoe bearing bearing shell
[technical field]
The present invention relates to the plant equipment field, relate in particular to a kind of devices and methods therefor of installation or removal bearing bush, be specifically related to the devices and methods therefor of slide shoe bearing bearing shell in a kind of installation or removal large-sized grinder.
[background technology]
Known, the grinding machine that with the slide shoe bearing is support pattern is widely used in the mine as milling equipment, building materials, in the industry such as chemical industry and metallurgy, wherein the friction between slide shoe bearing and grinding machine rotating cylinder is sliding friction, be that slip ring on the grinding mill barrel slides at the babbit laminar surface, to reduce resistance, but along with domestic and international continuous increase to this type of grinding machine demand with to improving constantly that its accuracy of manufacture requires, have energy-conservation, efficiently, easy large-scale of operating maintenance, the ultra-large type grinding machine becomes development trend from now on, but the continuous increase along with the grinding machine volume, can cause load and the revolving body size of grinding machine also to increase thereupon, when grinding machine revolving body size increases, the bearing that supports the grinding machine revolving body also will increase thereupon, require bearing to possess the top load of bearing simultaneously, installation and removal are convenient, characteristics such as stable; Because load and appearance and size that conventional small grinding machine revolving body bears are smaller, so the bearing of its use generally all adopts a bearing shell to support, its intermediate bushing dismounting all is to withstand on the grinding machine revolving body with carriage, and then makes grinding machine revolving body and bearing shell disengagement back directly hang out bearing shell from both sides with lifting appliance with several jack stand carriages; And because load and the appearance and size of medium-sized grinding machine revolving body are bigger with respect to load and the appearance and size of small-sized grinding machine revolving body, the general structure that all adopts the slide shoe bearing of two bearing shells, namely supported the revolving body of grinding machine by the bearing shell of two symmetric arrangement, because load and the appearance and size of the grinding machine revolving body of two bearing shell slide shoe bearings are bigger slightly than small-sized grinding machine, can use carriage to withstand on the method that holds up the grinding machine revolving body on the grinding machine revolving body equally two bearing shells and grinding machine revolving body are thrown off, use lifting appliance to hang out two bearing shells respectively from both sides then; And for large-scale; the ultra-large type grinding machine; because the load that its bearing need bear is bigger; usually need to adopt the slide shoe bearing structure of many bearing shells; at the bearing shell of its slide shoe bearing of grinding machine of this class formation in maintenance or when changing; if still adopt carriage to withstand on the method that holds up the grinding machine revolving body on the grinding machine revolving body; the grinding machine revolving body is deformed and damage grinding machine; most importantly because of large-scale; the production capacity of ultra-large type grinding machine is very big; if because maintenance causes large-scale; the shutdown for a long time of ultra-large type grinding machine can cause the loss that delays work greatly; therefore; device at the bearing bush installation or removal will possess safe and reliable and easy to operate; the shutdown loss that the maintenance of characteristics, and then minimizing efficiently causes.
At present, the difficult point at the bearing shell installation or removal of many bearing shells slide shoe bearing mainly contains the following aspects:
The one, load large-scale, that the bearing of ultra-large type grinding machine need bear is very big, because the grinding machine revolving body is a kind of thin-wall tubular structure, carriage can only jacking on position very little on the grinding machine revolving body, and then cause grinding machine revolution lifting surface area little, load is big, very easily makes grinding machine revolving body distortion and damages;
The 2nd, bearing shell appearance and size and weight large-scale, ultra-large type grinding machine slide shoe bearing are all bigger, and the operating space is smaller, depend merely on manpower and small-sized machine instrument and are difficult to mobile bearing shell;
The 3rd, appearance and size large-scale, ultra-large type grinding machine revolving body is very big, the bearing shell of many bearing shells slide shoe bearing can not directly be lifted by crane, if mobile bearing shell main equipment does not have the operating space again from the below from the top;
The 4th, the bearing shell of many bearing shells slide shoe bearing is many, generally is that the monolithic bearing shell damages when bearing shell damages, if middle bearing shell needs dismounting, then need remove the bearing shell of both sides earlier, vacate the withdrawal space, the bearing shell that damages in the middle of could dismantling has again greatly increased the time of dismounting and installation bearing shell etc.
In sum, how to provide the device of slide shoe bearing bearing shell in a kind of suitable installation or removal large-sized grinder and the long-term technology demand that the installation or removal method has just become those skilled in the art.
