Abstract
The invention discloses a single-roller grate plate free of frequent replacement. The single-roller grate plate free of frequent replacement comprises a grate plate body. A protective plate is arranged on the grate plate body. A cavity with the section being in the shape of an isosceles trapezoid is formed below the protective plate. First oblique planes which incline outwards are arranged on the two sides of the protective plate. The single-roller grate plate free of frequent replacement is characterized in that a first boss with the section being in the shape of an inverted isosceles trapezoid is fixedly arranged on the upper plane of the fixed end of the grate plate body, and the inner side of the boss is provided with a second oblique plane parallel to the first oblique planes; the single-roller grate plate free of frequent replacement further comprises a movable block, and one side of the movable block is provided with a second boss which can be inserted into the cavity and a third oblique plane which is parallel to the first oblique planes or the second oblique plane; and a dovetail mortise which is open on the other side of the movable block and penetrates through the lower plane of the outside of the second boss is further formed in the movable block, the dovetail mortise can allow the first boss to be inserted therein, and the section of the dovetail mortise is in the shape of an inverted isosceles trapezoid. Compared with the prior art, the movable block at the fixed end only needs to be horizontally moved towards the inner side when replaced, and the movable block can be taken out after sliding out of the first boss. Replacement of the whole grate plate is not needed.
Description
Technical field
The present invention relates to sintering technology field, be specifically related to a kind of single roller grate plate without frequently changing.
Background technology
Single roll crusher is one of key equipment in steel mill's SINTERING PRODUCTION, it is responsible for the broken task of sinter cake, it is arranged on sintering machine afterbody, be used for crush sintered after, the bulk sintering deposit cake unloaded down from pallet, it is broken into the appropriate particle size meeting technological requirement, its operating temperature is up to 850 ~ 1000 DEG C, due to long-term at high temperature, heavy duty, move under the environment such as large impact, therefore the fixing end abrasion of the grate plate of single roller breaker is very fast, the usually rotor hung above backplate because fixing end abrasion is had to, the grate plate more renewed, owing to the weight of every piece of single roller grate plate is bigger, generally weight is up to 6-7 ton, and the grid section of every piece of single roller grate plate the most up to tens, only because fix the abrasion of end and change whole single roller grate plate, have a strong impact on production and cause huge waste of material.
Summary of the invention
For overcoming the deficiencies in the prior art, the present invention discloses a kind of single roller grate plate without frequently changing, taked technical scheme be:
A kind of single roller grate plate without frequently changing, including grate plate body, on grate plate body, backplate is set, the cavity that cross section is isosceles trapezoid is set below described backplate, the both sides of backplate arrange the first outward-dipping inclined-plane, it is characterized in that: the first boss in isosceles trapezoid of the fixed cross section of upper plane at the fixing end of grate plate body, the inner band of boss is parallel to second inclined-plane on the first inclined-plane；Also include a loose piece, the side of described loose piece arranges and can be inserted into the second boss of cavity, is parallel to the 3rd inclined-plane on the first inclined-plane or the second inclined-plane, also setting up on loose piece and be opened on loose piece opposite side and the dovetail fourth of the twelve Earthly Branches of the lower plane in addition to crossing the second boss, the dovetail fourth of the twelve Earthly Branches can hold the first boss insertion and its cross sectional shape in isosceles trapezoid.
Further, the top built-up welding heat-resistant antifriction layer of loose piece.Extend loose piece service life, and then the extension device time between overhauls(TBO).
Compared with prior art, the present invention has a characteristic that
One, process dovetail shaped the first boss in grate plate, loose piece is processed the corresponding dovetail fourth of the twelve Earthly Branches, for bearing external force (compressing downwards backplate) upwards.
Two, continued the second boss on loose piece the 3rd inclined-plane, prevents from moving outside loose piece, as long as translated to inner side by loose piece when changing fixing end loose piece simultaneously, skids off the first boss and just can upwards take out loose piece.
Three, continued the second boss on loose piece the 3rd inclined-plane, positions simultaneously as backplate, limits the displacement in backplate totally 5 directions upper and lower, right, forward and backward.

Detailed description of the invention
See accompanying drawing, a kind of single roller grate plate without frequently changing, including grate plate body 1, backplate 2 is set on grate plate body 1, the cavity 21 that cross section is isosceles trapezoid is set below described backplate 2, the both sides of backplate 2 arrange the first outward-dipping inclined-plane 22, it is characterised in that: first boss 11 in isosceles trapezoid of the fixed cross section of upper plane at the fixing end of grate plate body 1, the inner band of boss 11 is parallel to second inclined-plane 12 on the first inclined-plane 22；Also include a loose piece 3, the side of described loose piece 3 arranges and can be inserted into the second boss 31 of cavity 21, is parallel to the first inclined-plane 22 or the 3rd inclined-plane 32 on the second inclined-plane 12, also setting up on loose piece 3 and be opened on loose piece opposite side and except the dovetail fourth of the twelve Earthly Branches 33 of the lower plane crossed in addition to the second boss, the dovetail fourth of the twelve Earthly Branches 33 can hold the first boss 11 and insert and its cross sectional shape is in isosceles trapezoid.The top built-up welding heat-resistant antifriction layer of loose piece 3.
Claims (2)
1. the single roller grate plate without frequently replacing, including grate plate body, on grate plate body, backplate is set, the cavity that cross section is isosceles trapezoid is set below described backplate, the both sides of backplate arrange the first outward-dipping inclined-plane, it is characterized in that: the first boss in isosceles trapezoid of the fixed cross section of upper plane at the fixing end of grate plate body, the inner band of boss is parallel to second inclined-plane on the first inclined-plane；Also include a loose piece, the side of described loose piece arranges and can be inserted into the second boss of cavity, is parallel to the 3rd inclined-plane on the first inclined-plane or the second inclined-plane, also setting up on loose piece and be opened on loose piece opposite side and the dovetail fourth of the twelve Earthly Branches of the lower plane in addition to crossing the second boss, the dovetail fourth of the twelve Earthly Branches can hold the first boss insertion and its cross sectional shape in isosceles trapezoid.
