Abstract

The utility model belongs to the technical field of auxiliary equipment of a rolling mill, and particularly relates to a 350-short-stress rolling mill rapid roll-changing device. The 350-short-stress rolling mill rapid roll-changing device solves the problem that in the practical production, the replacement of the rolling mill needs a lot of time. The 350-short-stress rolling mill rapid roll-changing device comprises two sets of roll-changing carts, wherein the roll-changing carts are arranged on a rail, comprise a horizontal roll-changing cart and a vertical roll-changing cart, and are connected with each other, a translation oil cylinder is arranged at the bottom of the horizontal roll-changing cart, a horizontal lifting cylinder is arranged at one side of the upper surface of the horizontal roll-changing cart, two supporting carts are arranged on the upper surface of the vertical roll-changing cart, and a vertical roll-changing oil cylinder is arranged at one end of each supporting cart. The 350-short-stress rolling mill rapid roll-changing device has the advantages of being simple in operation, reliable in equipment, and low in maintenance cost, achieving multi-roll and one-time replacement, improving work efficiency, and largely improving allocation quota management on the production site, environment protection and other aspects.

Description

350 short stress milling train fast roll changing devices

Technical field

The utility model belongs to the technical field of milling train auxiliary equipment, is specifically related to 350 short stress milling train fast roll changing devices.

Background technology

Milling train because of the rolling mill practice difference, needs to change different milling trains in the time of rolling products of different specifications, and particularly 350 finishing mills are more frequent.

There are 6 350 milling trains at present general steel rolling scene, and the working site can only have two high cars to change standby host simultaneously at most, changes frame 30-40 minute at least, and two high car independent body work are all changed 1.5-2 hour at least for 6, change successively.This need spend long time.

Summary of the invention

The utility model is changed problems such as the milling train spended time is more in order to solve in actual production, and a kind of 350 short stress milling train fast roll changing devices are provided.

The utility model adopts following technical scheme to realize:

350 short stress milling train fast roll changing devices, comprise two cover roll change dollies, roll change buggy is laid in orbit, described roll change buggy comprises horizontal roll change buggy and vertical roll change buggy, two cover dollies are connected to each other, and described horizontal roll change buggy bottom is equipped with translation oil cylinder, and a side of upper surface is equipped with level and draws high cylinder, described vertical roll change buggy upper surface is equipped with two support dollies, at an end that supports dolly vertical roll change oil cylinder is installed.

Connected by shaft coupling between the described roll change buggy.

There are two milling trains to place the position on each roll change buggy.

Several roll change buggies link into an integrated entity by jockey, and the displacement of dolly when the translation oil cylinder bottom roll change buggy changes milling train has two milling trains to place the position on each roll change buggy.Horizontal mill by level draw high cylinder directly with the milling train push-and-pull to roll change buggy, vertical mill will support the dolly push-and-pull to roll change buggy by vertical roll change oil cylinder.

The utlity model has following beneficial effect:

Simple to operate, equipment is reliable, maintenance cost is low, realized many sorties, disposable replacing, has improved operating efficiency, and there is great raising aspects such as the configuration quota management of production scene, environmental protection.

Concrete enforcement

By reference to the accompanying drawings the specific embodiment of the present utility model is described further.

350 short stress milling train fast roll changing devices, comprise two cover roll change dollies, roll change buggy is placed on the track 7, described roll change buggy comprises horizontal roll change buggy 10 and vertical roll change buggy 6, two cover dollies are connected to each other, and described horizontal roll change buggy bottom is equipped with translation oil cylinder 9, and a side of upper surface is equipped with level and draws high cylinder 11, described vertical roll change buggy upper surface is equipped with two support dollies 5, at an end that supports dolly vertical roll change oil cylinder 12 is installed.

Connected by shaft coupling 8 between the described roll change buggy.

There are two milling trains to place the position on each roll change buggy.

Several roll change buggies link into an integrated entity by jockey, and the displacement of dolly when realizing changeing milling train by the traversing cylinder assembly of roll change buggy bottom has two milling trains to place the position on each roll change buggy.Horizontal mill by level draw high cylinder 11 directly with the milling train push-and-pull to roll change buggy, vertical mill will support dolly 5 push-and-pulls to roll change buggy by vertical roll change oil cylinder 12.

When changing standby host, the milling train that will replace is released by translation oil cylinder 9 or vertical roll change oil cylinder 12, extract bearing pin, horizontal roll change buggy 10 or vertical roll change buggy 6 are passed a milling train body position with the car body that links together below this device then, the standby host of replacing just in time aligns roll change cylinder cylinder head, insert bearing pin, the roll change cylinder is namely finished the replacing standby host with the milling train working position of pulling back.
