Abstract
The invention relates to a lifting device for a rolling mill track. The lifting device comprises the rolling mill track, track connecting blocks, hydraulic cylinders and piston rods, wherein the track connecting blocks are fixedly connected to the two sides of the bottom of the rolling mill track separately; one hydraulic cylinder is arranged at the bottom of each track connecting block; the piston rods are coaxially assembled at the tops of the hydraulic cylinders, move up and down under driving of the hydraulic cylinders and realize coaxial propping press fit with the corresponding track connecting blocks. According to the direct-lift type lifting device for the rolling mill track, the processing period is short, the equipment upgrading cost is low, a T-shaped head structure of an original design scheme is canceled, and the distance between the two track hydraulic cylinders after improvement is 1,320 mm. Therefore, the effective passing width of cold-rolling strip steel is greatly increased, the track hydraulic cylinders cannot be scratched when raw materials are off tracking, and accordingly, waste products are avoided.
Description
Technical field
The invention belongs to milling train auxiliary equipment field, particularly a kind of lifting device for milling train track.
Background technology
At present, mostly known milling train track lifter is to adopt the mode of track hydraulic cylinder jacking track to realize, this track lifter installs T-shaped top at hydraulic cylinder top, top realizes synchronous rising and the decline of track by contiguous block, fixed block is bolted on track, thus achieve lifting track and decline synchronous with the action of track hydraulic cylinder, because structure is simple, practical effect is widely used in field of metallurgical equipment well.Find because lifting track hydraulic cylinder needs to be connected with track contiguous block by T-shaped piece in actual use, this structure compares waste for the relatively compact device space of structure, the distance between two track hydraulic cylinders is caused to be 1150mm, this just have impact on the effective in width of cold-strip steel, also affects to some extent mill milling product specification.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, propose a kind of saving space more and add the lifting device for milling train track that band steel is suitable for specification.
The present invention solves its technical problem and takes following technical scheme to realize:
A kind of lifting device for milling train track, comprise milling train track, track contiguous block, hydraulic cylinder and piston rod, milling train rail base both sides are fixedly mounted with a track contiguous block respectively, a hydraulic cylinder is respectively arranged with bottom each track contiguous block, hydraulic cylinder top is coaxially fitted with piston rod, and this piston rod realizes upper and lower displacement by Driven by Hydraulic Cylinder and the track contiguous block corresponding with it realizes coaxial top press-fit.
And described rail base is fixedly mounted with track contiguous block by bolt.
Advantage of the present invention and good effect are
The invention provides a kind of lifting device for milling train track directly putting forward formula, the process-cycle is short, and scrap build expense is low, eliminates the T connector structure of former design, and the distance between two track hydraulic cylinders after improvement is 1320mm.This just makes the effective of cold-strip steel greatly be increased by width, also can not scratch when raw material generation deviation phenomenon track hydraulic cylinder and produce waste product, simultaneously because the band steel added between track hydraulic cylinder effectively passes through width, the specification kind of cold-rolled products have also been obtained increase, achieves cost efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Be further described the invention process below in conjunction with accompanying drawing, following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.
A kind of lifting device for milling train track, comprise milling train track 4, track contiguous block 1, hydraulic cylinder 3 and piston rod 2, be described for milling train monorail in accompanying drawing, in actual production, increase and decrease according to the number of lifting device according to milling train track, milling train rail base both sides are fixedly mounted with a track contiguous block respectively by bolt 5, a hydraulic cylinder is respectively arranged with bottom each track contiguous block, hydraulic cylinder top is coaxially fitted with piston rod, this piston rod realizes upper and lower displacement by Driven by Hydraulic Cylinder and the track contiguous block corresponding with it realizes coaxial top press-fit.
Although disclose embodiments of the invention and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the present invention and claims, various replacement, change and amendment are all possible, therefore, scope of the present invention is not limited to the content disclosed in embodiment and accompanying drawing.
