Abstract
The invention discloses a lining plate device for an impact plate of an impact crusher, which comprises an impact plate body and a lining plate, wherein the lining plate is fastened on the impact plate body through a connecting bolt; the contact surfaces of the impact plate body and the lining plate are respectively provided with a transverse square groove at corresponding positions; a square key pin is keyed in a square hole formed by closing the two square grooves; or, the surface of the impact plate body in contact with the lining plate is provided with a transverse square groove, the surface of the lining plate in contact with the impact plate body is provided with a transverse square convex key corresponding to the transverse square groove, and the square convex key and the square groove are closed together. The lining plate device disclosed by the invention can transfer the transverse impact force applied to the lining plate to the impact plate body so that the shear force and the transverse impact force borne by the bolt used for connecting the lining plate with the impact plate body are greatly reduced, and the accident of falloff of the lining plate, caused by cracking and loosening of the bolt, is prevented effectively. Meanwhile, the used impact plate lining plate with a thrust structure is convenient to install and maintain, the lining plate is positioned safely and reliably, and the service life of the impact plate is prolonged effectively.
Description
Technical field
The present invention relates to a kind of counterpunch board of impact breaker, is a kind of liner plate device of impact breaker counterpunch board specifically.
Background technology
As everyone knows, impact breaker is that the impulsive force of utilizing the rotor high-speed rotation to produce is come broken material, material is pulverized after by the strike of rotor upper ram, simultaneously self also have certain kinetic energy, material at a high speed hits counterpunch board and carries out further fragmentation, and the material that drops of bounce-back is hit by tup again then, through after the fragmentation so repeatedly, when raw meal particle size during, will be discharged from this crusher chamber less than the gap of counterpunch board bottom and rotor cylindrical.Counterpunch board is the critical component of disintegrating machine, and the quality of its design can directly have influence on machine performance.
Impact breaker is to adopt the impact principle broken material, counterpunch board not only will bear the bump of the material that splashes at work, and when falling into the bottom eck, bulk materials also to be subjected to the huge extruding force of material to it, therefore counterpunch board in use weares and teares very fast, for the ease of the maintenance and the replacing of wearing piece, existing impact breaker is many to be provided with liner plate in counterattack plate body bottom, uses secondary liner plate and the counterattack plate body of connecting of bolt, liner plate for convenience detach, the service life of improving counterpunch board.But in the impact breaker course of work, counterpunch board is subjected to the enormous impact of material to it, make connecting bolt bear huge shear stress, cause the connecting bolt well damage, connecting bolt often occurs and cut short the situation that causes the counterpunch board liner plate to drop, this kind situation occurring mainly is that liner plate is not enough with counterattack plate body bonding strength, the bottom of counterpunch board is subjected to the oblique impulsive force of material, therefore lining-plate bolt is subjected to the effect (shown in figure .3) of two component of vertical and horizontal simultaneously, the failure mode of liner plate connecting bolt shows as shear fracture, causes liner plate to drop.
Summary of the invention
The objective of the invention is to overcome the defective that prior art exists, a kind of liner plate device of impact breaker counterpunch board is provided, it can reduce the shear stress of impact breaker counterpunch board liner plate connecting bolt carrying.
Concrete technical scheme is: the liner plate device of impact breaker counterpunch board of the present invention, comprise counterattack plate body, liner plate, and liner plate is fastened on the counterattack plate body by connecting bolt.It is characterized in that: between the contact-making surface of liner plate and counterattack plate body, be provided with horizontal pin key mechanism.
Described pin key mechanism is that corresponding position is opened a horizontal square groove separately on counterattack plate body and liner plate contact-making surface, fastens the square key pin of key entry in the square hole that forms at two square grooves; Or, on the contact-making surface of counterattack plate body and liner plate, open a horizontal square groove, the position correspondence is established a horizontal square protruding key on liner plate and counterpunch board contact level with it, and square protruding key and square groove fasten.Also can be on liner plate and counterattack plate body, square protruding key and square groove oppositely to be provided with.
Beneficial effect of the present invention is that the lateral impact forces that this counterpunch board can be subjected to liner plate passes on the counterattack plate body, thereby the bolt that has reduced to connect liner plate and counterattack plate body greatly is subjected to shearing force and lateral impact forces, has effectively prevented the fracture of bolt and gets loose and the accident that causes liner plate to drop takes place.Simultaneously, use the counterpunch board liner plate of thrust structure convenient for installation and maintenance, the liner plate positioning security is reliable, has effectively prolonged the service life of counterpunch board, has reduced the maintenance time of equipment.

Fig. 2 is the zoomed-in view of the local I of Fig. 1, comprises the schematic diagram of the force bearing of lining plate of counterpunch board.
Fig. 3 is the impact breaker structural representation.
Fig. 4 is the counterpunch board structural representation (square protruding key and square groove manner) of the liner plate device of use impact breaker counterpunch board of the present invention.
The specific embodiment
Be further detailed below with reference to Fig. 1,2,3,4 pairs of these patents.
As shown in Figure 1, 2, the liner plate device of impact breaker counterpunch board comprises counterattack plate body 2, liner plate 4, and liner plate is fastened on the counterattack plate body by connecting bolt 5.Between the contact-making surface of liner plate and counterattack plate body, be provided with horizontal pin key mechanism.This pin key mechanism is that corresponding position is opened a horizontal square groove separately on counterattack plate body and liner plate contact-making surface, fastens at two square grooves and keys in square key pin 3 in the square hole that forms.
As shown in Figure 4, described pin key mechanism can also be, opens a horizontal square groove on the contact-making surface of counterattack plate body and liner plate, and the position correspondence is established a horizontal square protruding key 6 on liner plate and counterpunch board contact level with it, square protruding key and square groove fastening.Also can be on liner plate and counterattack plate body, square protruding key and square groove oppositely to be provided with.
