Abstract
The utility model discloses a coal breaker abrasionproof welt, solves the difficult maintenance of coal breaker abrasionproof welt and the difficult problem changed, solves long -term use of coal breaker simultaneously and leads to the problem that is prone to accidents behind the bolt looseness, technical scheme: a coal breaker abrasionproof welt, is including setting up the square plate body of notched, characterized by: an arc arch is welded respectively to the upper portion and the lower part of plate body, the middle part of plate body sets up the screw hole, and through the square fixed plate of bolted connection, the whole welding of fixed plate sets up the screw hole at its middle part on the organism, and portion and lower part set up curved recess respectively above that, and this utility model is convenient for change and the maintenance, takes place the accident can not appear under the not hard up circumstances at the long -term back bolt that uses, can effectively guarantee the production safety.
Description
Technical field
This utility model relates to coal breaker auxiliary device field, is specifically related to a kind of wear-resistant liner of coal crusher.
Background technology
Coal breaker is device commonly used during power plant produces, during coal breaker uses, due to flywheel wear reason, cause disintegrating machine internal fracture plate, sieve plate and wear strip deformation, affect coal crushing and become granule, thus occur in that the abrasion-resistant lining plate improving coal breaker service life, the utility model patent of Patent No. 201120131604. 1 discloses a kind of wear-resistant liner of coal crusher, efficiently solve disintegrating machine internal fracture plate, sieve plate and wear strip problem on deformation, improve the service life of coal breaker, but, this utility model easily breaks down due to bolt absent-mindedness after a long time use, plate body vibration simultaneously improves the noise in workshop, and waste time and energy very much changing and keeping in repair this link.
Utility model content
The purpose of this utility model is aiming at the deficiency that prior art exists, open a kind of wear-resistant liner of coal crusher, solves wear-resistant liner of coal crusher not easy-maintaining and a difficult problem for replacing, the problem simultaneously solving to be prone to accidents after coal breaker life-time service causes bolt looseness.
Technical scheme: a kind of wear-resistant liner of coal crusher, including arranging jagged square plate body, it is characterized in that: the upper and lower of described plate body is respectively welded an arc convex, the middle part of described plate body is threaded hole, it is bolted square fixed plate, fixed plate integral solder, on body, is threaded hole in the middle, is respectively provided with the groove of arc at an upper portion thereof and at a lower portion thereof.
The inside of the groove of described arc arranges rubber layer.
Beneficial effect: this utility model can not only reach prior art and improve the effect in coal breaker service life,
And easy to replace and maintain by the way of screwing, a bolt need only be tightened, rubber layer can buffer part vibration, and bolt does not haves accident in the case of occurring to loosen after long-term use, it is possible to production safety is effectively ensured.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the present embodiment.
Accompanying drawing 2 is the elevational schematic view of part A in accompanying drawing 1.
Accompanying drawing 3 is the elevational schematic view of part B in accompanying drawing 1.
Detailed description of the invention
Referring to the drawings 1,2,3, a kind of wear-resistant liner of coal crusher, including arranging jagged square plate body 5, it is characterized in that: the upper and lower of described square plate body 5 is respectively welded an arc convex 4, the middle part of described square plate body 5 is threaded hole, connects square fixed plate 3 by bolt 8, square fixed plate 3 integral solder is on body 1, being threaded hole 2 in the middle, be respectively provided with the groove 7 of arc at an upper portion thereof and at a lower portion thereof, the inner side of the groove 7 of described arc arranges rubber layer 6.
This utility model is by rotating square plate body 5, arc convex 4 is made to screw in arc groove 7, bolt on 8 can complete install, also allow in this way changing square plate body 5, in the case of occurring that bolt 8 loosens after long-term use, the arc convex 4 owing to being welded on square plate body 5 is embedded in arc groove 7, and the most square plate body 5 will not drop out easily, absorbed by rubber layer 6 additionally due to bolt 8 loosens the vibration occurred, therefore in workshop, there will not be the biggest noise.
Claims (2)
1. a wear-resistant liner of coal crusher, including arranging jagged square plate body, it is characterized in that: the upper and lower of described square plate body is respectively welded an arc convex, the middle part of described square plate body is threaded hole, it is bolted square fixed plate, square fixed plate integral solder, on body, is threaded hole in the middle, is respectively provided with the groove of arc at an upper portion thereof and at a lower portion thereof.
A kind of wear-resistant liner of coal crusher the most according to claim 1, is characterized in that: the inside of described arc groove arranges rubber layer.
