Abstract
The utility model discloses a long-life abrasive resistant lining board for bulk freight operation hopper, compising a board (1) and a lining board fixing screw hole (2). A hollow boss (4) is provided at the joint side between the lining board fixing screw hole (2) and a hopper wall surface (3). An opening is arranged on the hopper wall surface (3). The hollow boss (4) is positioned in the opening. A bolt (5) is used to carry out fixing. The bolt square end of the lining board sinks into the bolt opening. The utility model is not easy to wear out and therefore improves the service life of the lining board.
Description
Technical field the utility model relates to a kind of parts of bulk goods implement, particularly a kind of abrasion-proof backing block of funnel.
The background technology abrasion-proof backing block is the inner requisite part of the funnel of bulk goods (ore, coal) implement.Traditional liner plate tow sides all are the planes, and the liner plate bolt of rear end plate passes the liner plate shrinkage pool and funnel back side nut is fixed, and the shortcoming of its structure is, when liner plate is worn down to a certain degree, the head of bolt also will be worn, in case bolt cap all grinds off, liner plate will come off.The liner plate that comes off is sneaked in the material, may cause the damage of flow process belt, brings huge property damage to enterprise.In order to prevent the generation of this phenomenon, operation field shortens the liner plate replacement cycle usually, promptly liner plate also quite thick, when bolt head is still unworn, just changed in advance.This way has increased productive costs undoubtedly, has increased the equipment downtime number of times, the corresponding increase of employee's labor content, and these phenomenons all are that enterprise is unwilling to see.
The summary of the invention the purpose of this utility model provides a kind of long-life abrasion-proof backing block.
The purpose of this utility model is achieved through the following technical solutions: a kind of long-life abrasion-proof backing block, comprise the fixing threaded hole of plate body and plate body, and it is characterized in that having the boss of hollow in a side of fitting with the funnel wall of liner plate fixing threaded hole.
The height of said boss is identical with the thickness of hopper walls in the technique scheme.
In this liner plate, because the existence of boss, the corresponding increase of the degree of depth of fixed bolt hole, the square toes of bolt can sink into the inside of bolt hole, and needn't be as existing technology surperficial parallel with liner plate, thereby no matter what degree the liner plate face is worn down to, and can not may wear to the bolt square toes, liner plate is in tightening state all the time, thereby has increased the service life of liner plate to greatest extent.
The utility model has the advantages that: one, the degree of utilization of liner plate increases, and prolong service life, reduced productive costs; Two, the liner plate case accident can not take place, guarantee job safety.Three, the maintenance number of times reduces, and is beneficial to the site tissue management.
Appended drawings is a structural representation of the present utility model.
The specific embodiment further specifies the utility model below in conjunction with accompanying drawing.
This long-life abrasion-resistant liner plate comprises the fixing threaded hole (2) of plate body (1) and plate body, and the boss (4) of hollow is arranged in the side with funnel wall (3) applying of liner plate fixing threaded hole (2).When this abrasion-proof backing block is installed, should go up perforate at funnel wall (3), make the boss (4) of hollow be arranged in this hole, use bolt (5) to pass the boss (4) of hollow then, the bolt square toes are arranged in fixing threaded hole (2), and the other end of bolt is fixed with big pad (6), elastomeric pad (7) and nut (8).
Through test, the more traditional liner plate of the degree of utilization of this long-life abrasion-resistant liner plate is compared and is improved 25%, and corresponding financial cost reduces by 25%, descends 30% during the serviceman.
Claims (2)
1, a kind of long-life abrasion-resistant liner plate comprises the fixing threaded hole of plate body and plate body, it is characterized in that having in a side of fitting with the funnel wall of liner plate fixing threaded hole the boss of hollow.
2, long-life abrasion-resistant liner plate according to claim 1 is characterized in that the height of said boss is identical with the thickness of hopper walls.
