Description
Technical field
The present invention relates to the installation method of three groups of cross-roll straightening machine radial type hoisting cross beams of a kind of seamless steel pipe, belong to
In metallurgical machinery equipment installing area.
Background technology
Seamless steel pipe rolling line produces to eliminate the impact of seamless steel pipe various factors in the operation of rolling
The defects such as shape, rolled piece needs to align on straightener, important during therefore straightener is Rolling production
Plant equipment.
Three groups of cross-roll straightening machines of seamless steel pipe (are used for containing three groups of hoisting cross beams by three groups of upper roller system adjusting apparatus
Smoothing roll Height Adjustment), the assembling of three groups of top working rolls, three groups of bottom working roll assemblings, lower roll system adjusting apparatus (use
In lower smoothing roll Height Adjustment), reclining apparatus (for smoothing roll angle adjustment), rack is (by upper horizontal stroke
Beam, lower bearing bracket and eight root posts composition, column applies pretightning force by hydraulic pre-tightening mode to upper lower bearing bracket),
Main drive, changing rig, straightener approach table, straightener runout table etc. form.The most main biography
Dynamic device is made up of mair motor, combining speed reducer, base, Hooks coupling universal coupling.Main drive has two sets,
A set of for upper straightening roll power, smoothing roll power under a set of offer.
The working roll of straightener has a similar hyp space curve shape, on three groups of bottom working rolls and three groups
Working roll axis crosses each other into hexagonal angle work, and three top working rolls can individually adjust, seamless steel pipe three
Group cross-roll straightening machine effect is after tubing enters into entrance guide groove, and entrance guide groove action makes tubing centering enter
Straightener；When tubing head arrive first to smoothing roll after, the upper roller of roller is quickly depressed by this, in like manner second,
3rd smoothing roll action successively is quickly depressed, and tubing is after straightener back warp is crossed and is repeatedly rotationally advancing flexural deformation
It is straightened.
Three groups of hinge type hoisting cross beams of three groups of cross-roll straightening machines of seamless steel pipe are mutually hinged, hinged rear formation
8 groups of through holes with penetrate gap and only have 8 root posts of 1mm to carry out the Special complex structure assembled.Therefore this
Kind of three groups of hinge type hoisting cross beam structures of Special complex and fit-up gap less be the difficult point in installing.Common
Installation method is: four root posts outside four root posts or two in the middle of first installing, then packet lifting hoisting cross beam.
The method one is that hoisting cross beam cannot form hinge format installation；Two is the sky that another four root posts are installed at factory building
Between not.This just installation to three groups of hinge type hoisting cross beams of three groups of cross-roll straightening machines of seamless steel pipe cause very
Big difficulty.
Summary of the invention
It is an object of the invention to provide a kind of can be with the seamless steel pipe three of three groups of hinge type hoisting cross beams of Fast Installation
The installation method of group cross-roll straightening machine radial type hoisting cross beam.
Technical scheme is as follows:
Sill is arranged on base, 8 root posts are fixed on sill, at lower horizontal stroke by design requirement
Bottom working roll is installed on beam；Three groups of hinge type hoisting cross beams are carried out hinged by mounting distance on ground, profit
It is grouped integral hoisting hinge type hoisting cross beam, then each with the bridge crane chain block of band crossbeam
Jack is placed by support means in bottom working roll bearing block top, and each jack all lifts horizontal stroke with being arranged on
A top working roll bearing block on beam is corresponding；Falling chain block after rise, three groups of hinge type hoisting cross beams are the most right
Answer 8 root post axles, and three groups of hoisting cross beams are arranged on cooperation by the method buffering jack one by one simultaneously
Gap only has on the 8 root post axles of 1mm.
The invention have the advantage that and do not limited by factory building installing space, installation rate is fast, installation accuracy is high,
Installation cost is low.
Accompanying drawing explanation
Fig. 1 is the installation schematic diagram of the present invention.
In figure: 1, hoisting hook beam, 2, hinge type hoisting cross beam, 3, top working roll, 4, column,
5, sill, 6, chain block, 7, jack 8, support means, 9, bottom working roll.
Detailed description of the invention
Embodiment:
Baogang is seamless, and Φ 460 mandrel mill-rolled steel pipe production line installing engineering is arranged symmetrically with two straighteners, and its structure is three
The labyrinth of group cross roll aligning, is maximum skew roller type structure straightener on Baogang's seamless steel tube production chain.
Referring to the drawings, installation steps are as follows:
1, after base, sill are installed, to 8 M240mm, the column bridge crane of long 4990mm
Lift by root, be fixed on sill by design requirement, by design requirement between the column on sill
Install bottom working roll.
2, the installation of top working roll: every hinge type hoisting cross beam of slinging, is screwed into setting by every top working roll
In top working roll bearing block on hinge type hoisting cross beam, fix with fixing bolt.
3, the installation of three groups of hinge type hoisting cross beams:
1) straightener hoisting cross beam is three groups of hinge type structures, is referred to as: hinge type hoisting cross beam.Three groups of hinges
Formula hoisting cross beam presses mounting distance composition articulated form on ground；
2) three groups of hinge type lifting horizontal strokes of 25+25t bridge crane hook beam chain block packet integral lifting are utilized
Beam and 8 root posts are the most relative；
3) support means (support bar) is placed on working roll bearing block top in each of the lower, on support means top
Place jack, corresponding with the top working roll bearing block being arranged on hinge type hoisting cross beam.
4) chain block is fallen after rise, three groups of the most corresponding 8 root post axles of hinge type hoisting cross beam, and by one by one
Three groups of hoisting cross beams are arranged on fit clearance simultaneously and only have the 8 root post axles of 1mm by the method for buffering jack
On, make column axle penetrate the installing hole of three groups of hinge type hoisting cross beams.
