Abstract
The utility model discloses a novel assembly structure of a grate bed end part, which mainly comprises a small shaft, a first clamp ring and a second clamp ring. The first clamp ring is matched by twosemicircles and spot-welded together, and the annular inner edge thereof is clamped into an annular groove by which the small shaft is positioned outside a lateral baffle plate; the second clamp ringis sleeved with the first clamp ring and spot-welded together, and the inner side thereof is supported on the annular outer edge of the first clamp ring. The structure solves the defect of the priorassembly structure, has the characteristics of not changing the prior mechanical performance and influencing an entire grate bed, is not deformed when being heated, can normally work under the high-temperature working environment of the grate bed of a drying grate and be continuously reused after a period of time at work as long as the bending torsion of the small shaft, which occurs, is correctedand the section is not deformed, and can not influence the production even if the deflection occurs, thereby improving the service life of the grate bed and simultaneously saving labor and material resources.
Description
Technical field
The utility model relates to the assembly structure of metallurgy industry pelletizing plant grate bed end.
Background technology
Drying grate produce pelletizing be with the even cloth of green-ball on the grate bed, the bed of combing moves to head, the dry I section of exhausting, the dry II section of exhausting, exhausting preheating section utilize the gas of different temperatures vertically to pass the bed of material green-ball is heated, so the grate bed will have stronger stationarity, and the assembling of the little axle of the major part of the bed of combing is a key, also is difficult point.
Little axle is positioned at the operation part of drying grate, bear bigger load and higher temperature, so require the intensity of little axle assembling and steady, hear resistance to get well.Be extensive use of split pin 2 fixing little axle 1 (seeing Fig. 1,2) at present, the material of split pin 2 is that the mechanical property of this structural carbon steel of Q215 is very general.This kind was assemblied under the situation of certain high temperature after operation a period of time; split pin is broken easily to cause going here and there about little axle and is moved; the bed of combing easily produces phenomenons such as sideslip, jam; will influence the normal operation of the bed of combing; the little axle and the split pin that must shutdown more renew; and quite bother when changing little axle and split pin, must be slit into a section to stuck little axle to take out little and split pin more renewing then.After using a period of time also similar phenomenon can appear, circulation and so forth, and influence is produced, and has wasted manpower and materials greatly, causes very big loss.
The utility model content
At the deficiency that prior art exists, the utility model aims to provide the comb bed end assembly structure of a kind of accurate positioning and dependable performance.
The technical solution adopted in the utility model is:
A kind of novel comb bed end assembly structure, comprise little axle, first snap ring and second snap ring, described first snap ring is combined spot-welded together by two semicircles, its annular inside edge snaps in little axle and is positioned at the outer cannelure of side shield, second snap ring entangles first snap ring and spot-welded together, and its medial support is on the annular outer edge of first snap ring.
Described first snap ring and second snap ring all adopt heat resisting steel to make.
The utility model has been avoided the defective of original assembly structure, have the advantages that not change original mechanical performance, the comb bed ensemble is not had influence, indeformable when being heated, in the high-temperature work environment of grate bed, can work normally, if little axle produces flexion torsion after work a period of time, but as long as section is indeformable, after rectification, still can continue to use, even the generation deflection can not influence production yet, when improving a service life of combing, manpower and materials have also been saved.
Description of drawings
Fig. 1 is the schematic diagram of the existing bed end assembly structure of combing;
Fig. 2 is that the K of Fig. 1 is to view;
Fig. 3 is the schematic diagram of the utility model comb bed end assembly structure;
Fig. 4 is that the C of Fig. 3 is to view.
Description of reference numerals is as follows:
1---little axle 2---split pin
3---first snap rings 4---, second snap ring
5---side shield 6---cannelure
7---little axle sleeve
The specific embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail.
As Fig. 3, shown in 4, this bed end assembly structure of combing is mainly by little axle 1, first snap ring 3 and second snap ring 4 are formed, little axle 1 is formed with cannelure 6 outside side shield 5, because the annular inside edge of first snap ring 3 will stick in annular Cao of little axle, therefore first snap ring 3 is designed to two semicircles, spot-welded together then, if have only first snap ring 3, it can't be fixed along with little 1 rotation, so must entangle first snap ring 3 and spot-welded together with second snap ring 4 again, the medial support of second snap ring 4 is on the annular outer edge of first snap ring 3, and first snap ring and second snap ring all adopt heat resisting steel to make, to guarantee its heat resistance.
The utility model is not limited to above-mentioned preferred forms, and anyone can draw other various forms of products under enlightenment of the present invention.Though but on its shape or structure, do any variation, every identical with the utility model or akin technical scheme is all within its protection domain.
Claims (2)
1, a kind of novel comb bed end assembly structure, it is characterized in that, comprise little axle, first snap ring and second snap ring, described first snap ring is combined spot-welded together by two semicircles, its annular inside edge snaps in little axle and is positioned at the outer cannelure of side shield, second snap ring entangles first snap ring and spot-welded together, and its medial support is on the annular outer edge of first snap ring.
2, novel comb bed end assembly structure according to claim 1 is characterized in that described first snap ring and second snap ring all adopt heat resisting steel to make.
