Description
Technical field
The present invention relates to a kind of cylindrical shell, grinding roller installation method, the invention particularly relates to horizontal roll grinder cylindrical shell, grinding roller installation method.
Background technology
First horizontal roll grinder that gets into commercial Application is to be developed by French plant equipment group (FCB) in the world; Be called HOROMILL; In 1993 since coming into operation in Italian cement plant, just receive much concern because of advantage such as its economize on electricity, low noise, low abrasion, less trouble.Nearly 20 tame cement production enterprises of existing more than ten countries are using horizontal roll grinder all over the world at present, and the existing two tame cement production enterprises of China have used this equipment, and first horizontal roll grinder was constructed and put into operation in Mudanjiang in 2003.In recent years, from the demand of domestic market, China has developed the roller mill for sleeping in of the series with independent intellectual property right.
Be accompanied by the successful Application of China's horizontal roll grinder in cement industry; Technical-economic index and environmental protection effect are remarkable; New Building Materials Co., Ltd in capital entrusted Beijing China Metallurgical Engineering Ltd and FCB group to develop jointly and built and is used to make steel scrap steel ground-slag mill recycling project sunshine; The debugging of test run is at present produced, and the reaction of each item index has all reached requirement, becomes the focus that domestic each commercial production producer falls over each other to understand.
No matter be first cement horizontal roll grinder of China in Mudanjiang; Still at the first in the world platform slag horizontal roll grinder at sunshine, in installation process, cylindrical shell and grinding roller are because weight and volume is huge; And there is not upper space to lift; With sunshine the slag horizontal roll grinder be example: cylindrical shell weight 68t, internal diameter 3800mm, external diameter 4680mm; Grinding roller weight 54t, length 6407mm all becomes the emphasis in the installation process.
Because installing, domestic horizontal roll grinder cylindrical shell and grinding roller still be in the stage of fumbling at present; There is not ripe mount scheme; Be with reference to the installation of making amendment of the interim assistance platform of external similar item; Size did not meet during this just caused amended interim assistance platform and equipment is connected easily, and stability also can't be guaranteed.
Summary of the invention
The object of the present invention is to provide a kind of horizontal roll grinder cylindrical shell, grinding roller installation method; Use this method can not only guarantee to install smoothly cylindrical shell and grinding roller; And improved the sizing control in the installation process greatly, and reduced in the installation process causing a deviation, finally help producing the back and safeguard.
A kind of horizontal roll grinder cylindrical shell of the present invention, grinding roller installation method, it may further comprise the steps:
(a) assistance platform is installed, the installation process of described assistance platform is following: (1) makes up ground, the stepped footing of described ground for being made up of upper strata step and lower floor's step; (2) erection unit base on the step of described upper strata; Left and right side at the end face of described plant bottom case is installed at least two left and right carriage pillars respectively; Left and right side at the end face of described upper strata step and lower floor's step is installed a plurality of left and right pillars respectively successively at interval; The left side side girder steel of elongated setting is installed at least on described two left tray pillars and a plurality of left pillar; The right side girder steel of elongated setting is installed at least on described two right carriage pillars and a plurality of right pillar; The centre of the upper strata step between described left and right avris girder steel and the end face of lower floor's step is installed a plurality of left and right intermediate studdles respectively successively at interval; The middle girder steel in a left side of elongated setting is installed on described a plurality of left intermediate studdles, the right middle girder steel of elongated setting is installed on described a plurality of right intermediate studdles, described left and right avris girder steel and left and right middle girder steel along continuous straight runs each other laterally arrange;
(b) will assemble the sliding machine of accomplishing lifts to the main orbit of the assistance platform of being made up of left and right avris girder steel;
(c) cylindrical shell is lifted to sliding machine;
(d) adopt pulling equipment traction sliding machine to stop until arriving the plant bottom case top by a side direction plant bottom case side shifting of main orbit;
(e) fixing sliding machine adopts adjustable hold-down support to support the outwardly directed crossbeam in the sliding machine left and right sides respectively;
(f) remove the left and right avris girder steel of plant bottom case position, adjustable hold-down support and utilize jack that sliding machine and cylindrical shell integral body are dropped on the plant bottom case then gradually descends;
(g) remove sliding machine;
(h) with inspection trolley be installed in left and right in the middle of on the Auxiliary Track of the assistance platform formed of girder steel;
(i) grinding roller is lifted to inspection trolley and penetrate cylindrical shell by a side direction plant bottom case side shifting of Auxiliary Track until inspection trolley and grinding roller integral body, connect grinding roller, extract inspection trolley out cylindrical shell at last by pulling equipment traction inspection trolley.
The invention has the beneficial effects as follows: adopt this method can reduce the probability that installation process produces error, the stability of platform also is guaranteed.Assistance platform translation construction utilize to be installed not only to have solved the problem that can't lift, perfect this type of construction method, and also final assistance platform can be done the production maintenance platform and uses.The making of platform can be adopted the steel construction section bar, convenient and quick construction, and this platform can all adopt the high-strength bolt assembling, and the mounting or dismounting tube is prone to help using repeatedly; Translation gliding process tube list, operation easily; Employing in place jack commonly used and hold-down support support by turns, and the control that need is reduced height is stable, can well guarantee equipment axis line position and levelness.
