Description
Technical field
The present invention relates to metal shaping equipment field, specifically, it is related to a kind of rolling for the installation fixation of milling train bottom
Machine gantry base device.
Background technology
Milling train, refers in completion stocking production overall process, realizes that the She Bei ﹐ of metal rolled process include Zhu and want She Bei ﹑
Fu helps She Bei ﹑ handling equipmenies and auxiliary device etc..For example, in the prior art, rolling mill main will be by roll-separating mechanism, pull bar
The equipment compositions such as assembling, the assembling of roll Zhuan Pei ﹑ guide beam devices, mobile base and changing rig.
Under normal circumstances, the installation of milling train needs routinely mechanical equipment installation technological requirement strict implement.Wherein, milling train
That installs mainly includes that rolling-mill housing is installed and hydraulic system is installed, and it is hanging for frame that rolling-mill housing installs the technology for mainly solving
The detection and adjustment of positional precision when dress and frame are installed.Among these, in frame mobile base assembling, be milling train install weight
Want link.Because mill load is larger in work progress, the roll-separating mechanism of part, pull bar, frame etc. on to rolling mill base
When carrying out dismounting lifting, the eyelet bolt for connecting milling train mobile base and frame can rotate or move axially, and then
Cause its danger for releasing, meanwhile, needing to rule the bearing pin of milling train mobile base assembling in construction, centering is installed.
Mobile base is generally consolidated in installation process by the way of bearing pin insertion eyelet bolt on existing milling train
It is fixed.Specifically, i.e., eyelet bolt is inserted from the bolt hole of mobile base upper end, and suspends to cause that the bolt of its bottom leads to
Hole overlaps with the bearing pin channel alignment in the mobile base.Then a length is sold directly to households axle to be inserted into from the bearing pin passage, and
Through the bolt hole of the eyelet bolt bottom, threaded portion and the eyelet bolt bottom bolt throughhole on the bearing pin
Internal thread is engaged, and screws bearing pin and completes installation process.
After long-term Construction practices, there is following technical problem in discovery, above-mentioned positioning and installation method：First, it is actual
At least two even many eyelet bolts are generally required in installation process, it is necessary to by many eyelet bolts respectively from mobile base
Multiple bolt holes be inserted into, it is necessary to it is artificial by eyelet bolt hovering to keep bolt hole and the movement of eyelet bolt bottom
Bearing pin channel alignment on base, the process is because of artificial operation so being difficult to keep stabilization, and have a strong impact on installation effectiveness.The
Two, after preliminary installation, on the one hand to make the connection of eyelet bolt and bearing pin more consolidate, on the other hand to make bearing pin in pin
It is not subjected to displacement in axis channel, is fixed by way of the perforate on bearing pin and fixed screw, but is found in practice of construction,
After bearing pin passes through bearing pin passage, screw is difficult to find fixed hole position accurately, screw fixed position deflection, shadow easily occurs
Installation effectiveness and fixed mass are rung, occurs that loosening is even damaged after permanent use.In addition, the above-mentioned this side of being connected
Formula, seem extremely inconvenience in demolishing process.
In view of this, should provide one kind can be while installation quality be ensured so that look for position more accurate
The content of the invention
