Abstract
The present invention provides a ring cold machine slewing frame circularity adjusting method, which comprises the following steps: 1, assembling a slewing frame and trolleys to be a circle; 2, adjusting a side roller bottom backing plate to make sure the size from a top face of a side roller to an internal frame can reach the drawing requirement; 3, increasing radius of the framework connected with each triangle beam and connecting the framework with a side rail beam by a channel steel; 4, equally dividing the framework to be a plurality of equal parts, and welding one equal part for each welder who welds the bracket joint according to the circumferential welding method; 5, arranging an inner and an outer reinforcing plates and spot welding the inner and the outer reinforcing plates to an inner and an outer frameworks, and the welding method and the sequence are as same as the bracket joint welding; 6, simultaneously cutting off the connection channel steel according to the equal parts; 7, after aging treatment for 1 to 2 weeks, rotating the whole framework, and adjusting the side roller bottom backing plate. The increased or removed thickness of the backing plate is the ovality of the slewing frame, and the whole slewing frame circularity adjusting is finished. The present invention has the advantage of accurately adjusting the circularity of the ring cold machine to allow smooth operation of the whole framework and trolleys.
Description
Technical field:
The invention belongs to a kind of circularity adjusting process, particularly a kind of ring cold machine slewing frame circularity adjusting method.
Background technology:
The cooling of sintering deposit is a very important ring in SINTERING PRODUCTION technique, and cooling sintering deposit is generally used annular cooler at present.Annular cooler is to purchase car by a plurality of chassis that are mutually permanently connected, on chassis, be equipped with and need cooling sintering deposit, chassis and inside and outside slewing frame are fixed, bogie wheels is supported on circular orbit, drive unit drives revolution frame beam, slewing frame and chassis are done gyration, and air cooler makes cold air pass the bed of material and realizes the cooling of sintering deposit.The circularity of central cooler slewing frame affects the smoothness of operation of whole framework and chassis, so the adjustment of slewing frame circularity is very important work in whole central cooler installation.And welding sequence and erection sequence directly affect the circularity of slewing frame.
Summary of the invention:
Object of the present invention is just to provide a kind of ring cold machine slewing frame circularity adjusting method, can accurately adjust the circularity of central cooler slewing frame by the method.
Technical scheme of the present invention is: a kind of ring cold machine slewing frame circularity adjusting method, is characterized in that: according to the following step, carry out: (1) is assembled into circle by slewing frame and chassis; (2) adjust side running roller backing plate at bottom, make side running roller end face reach drawing requirement to inner frame size; (3) welding deformation amount providing according to design, the radius of each triangular beam institute connecting frame of corresponding increase, and with channel-section steel, framework is connected with siding track beam, keep the size after framework increases; (4) according to chassis quantity, framework is divided into some equal portions, each welder welds equal portions, and welder welds outside framework external angle plate, outside framework internal angle plate, inner frame external angle plate, inner frame internal angle plate by circumferential welding simultaneously; (5) inside and outside stiffener is installed and its point is welded on internal and external frames frame, welding method is identical with gusset welding with order; (6) by equal portions, cut off connection channel-section steel simultaneously; (7) Ageing Treatment 1-2, after week, rotates whole framework, the gap of observation side running roller and siding track, do not reach individually requirement, adjust side running roller backing plate at bottom, increase or the plate thickness of removing are the ovality of slewing frame, and so far whole slewing frame circularity is adjusted complete.
Advantage of the present invention is: can accurately adjust the circularity of central cooler slewing frame, make the smooth running of whole framework and chassis.
The specific embodiment:
A ring cold machine slewing frame circularity adjusting method, carries out according to the following step: (1) is assembled into circle by slewing frame and chassis; (2) adjust side running roller backing plate at bottom, make side running roller end face reach drawing requirement to inner frame size; (3) welding deformation amount providing according to design, the radius of each triangular beam institute connecting frame of corresponding increase is to 8-10, and with channel-section steel, framework is connected with siding track beam, keeps the size after framework increases; (4) according to chassis quantity, framework is divided into some equal portions, each welder welds equal portions, and welder welds outside framework external angle plate, outside framework internal angle plate, inner frame external angle plate, inner frame internal angle plate by circumferential welding simultaneously; (5) inside and outside stiffener is installed and its point is welded on internal and external frames frame, welding method is identical with gusset welding with order; (6) by equal portions, cut off connection channel-section steel simultaneously; (7) Ageing Treatment 1-2 is after week, with interim whole framework, the gap of observation side running roller and siding track of rotating of hoist engine, do not reach individually requirement, adjust side running roller backing plate at bottom, increase or the plate thickness of removing are the ovality of slewing frame, and so far whole slewing frame circularity is adjusted complete.Above-mentioned chassis is 99 o'clock, and slewing frame is divided into 11 deciles.
