Description
Technical field
The invention belongs to field of metallurgical equipment, the single-tooth roller of dismounting and change is facilitated to crush in more particularly to a kind of sintering production
Machine grate plate protects loose piece.
Technical background
Finished product sintering deposit generally is crushed using single-tooth roller in sintering production, the toothrow of interlaced arrangement three is preced with circular shaft,
The bottom of axle is uniformly arranged grate plate, when the shaft is rotated, crown between the gap between grate plate by the way that the bulk above grate plate will be fallen on
Sintering finished ores are broken into the fritter sintering deposit less than grate plate gap.
Because the temperature of sintering deposit is more than 300 DEG C, hardness has decline by a relatively large margin to grate plate at high operating temperatures, and
For a long time by it is broken when impacted, the rate of wear is very fast, and the service life of most domestic grate plate was less than 1 year, it is often necessary to
Grate plate is all changed, larger sintering machine will change 20 polylith grate plates, cause downtime longer, influence the operation of sintering machine
Rate, it is also desirable to larger fund.Domestic sintering industry and manufacture single roll crusher industry all find replacing construction it is short, can
In the method for local replacing, more meet the needs of sintering production.It is in grate plate sheet to improve the service life of rod-toothed crusher
Loose piece or protective cap are inlayed in the upper surface of body, and the prior art patent No. 201020638693.4 discloses a kind of single-tooth roller and crushed
The combination grate plate of machine；Mainly be connected activity helmet by grate plate body, with this grate plate body, and the right-hand member of its movable helmet passes through pressure
Block is connected with grate plate body, and groove is provided with grate plate body upper part, is provided with boss in movable helmet bottom, both pass through boss
Connected with groove, although this structure also has the advantages of processing protection is simple, and use cost is low, due on movable helmet
Provided with groove, movable helmet is easily broken along notch in the presence of high temperature and mechanical force, influences the service life of movable helmet.
In order to solve this problem, the patent No. 200920137619.1 discloses a kind of sintering list roller with segmental protective cover and broken
Broken machine grate plate device ", the sintering single roll crusher grid plate device of segmental protective cover, but because its structure is also in grate plate sheet
Body top is provided with groove, and boss is provided with movable helmet bottom, and gap will occurs in upper plane when trapezoidal faces contact, and upper plane connects
The problems such as gap will occurs in trapezoidal faces when touching, rocked by loose piece after larger broken impulsive force, make loose piece abrasion speed
Degree is accelerated, and influences stability.
The patent No. 201420338281.7 discloses a kind of dovetail groove type grate plate with backplate ", the form such as its dovetail groove, this
All highly difficult when the installation of kind structure two pieces, dismounting, faying face is stuck under impact force, can not dismantle loose piece, exist in use
Contact area is small, it is desirable to which fit precision is high.
It can be seen that sintering industry all can facilitate dismounting and change loose piece seeking one kind, the combining form of service life length is combed
Plate, solve the problems, such as that prior art is present.
The content of the invention
Instant invention overcomes the shortcomings that prior art and deficiency, there is provided a kind of single roll crusher for facilitating dismounting and change is combed
Plate protects loose piece, effectively solves loose piece replacing construction length, and repair and maintenance labor intensity is big, reduces repair and maintenance expense.
The present invention is achieved through the following technical solutions：
A kind of single roll crusher grate plate for facilitating dismounting and change of the present invention protects loose piece, including grate plate body, with bag
Include grate plate body connection protection loose piece, it is characterised in that described protection loose piece by left part loose piece, right part loose piece and in
Portion's loose piece is formed, and the joint face of described left part loose piece and right part loose piece and grate plate body is up big and down small inclined-plane,
Joint face is lived to face directly with middle part, and the normal section of described left part loose piece and right part loose piece is triangular in shape for top, bottom
The elongate structure body of trapezoid grafting groove is provided with, bolt is provided with the middle and lower part of described left part loose piece and right part loose piece
Hole I；
The normal section of described middle part loose piece is that top is triangular in shape, and bottom is provided with the elongate structure of trapezoid grafting groove
Body, bolt hole II is also provided with the middle and lower part of described middle part loose piece；
Described grate plate body is that middle part is provided with the trapezoid being adapted with trapezoid grafting groove
The elongated grate plate of boss, bolt hole III, described left end are also provided with described grate plate body
The trapezoid grafting groove of portion's loose piece, right part loose piece and middle part loose piece and the whole trapezoid boss grafting of grate plate body
When plane at leave gap, and by fastening bolt, clamp nut and be arranged on spring pad between fastening bolt and clamp nut
Circle is fixedly connected.
Top in the trapezoid grafting groove of described left part loose piece and right part loose piece is close to middle part loose piece side
Provided with locating convex block I, it is provided with and left part loose piece and right-hand member on the correspondence position of the trapezoid boss of described grate plate body
The groove that portion's loose piece locating convex block correspondence position matches.
Locating convex block II is provided with the both sides of the trapezoid grafting groove inner top of described middle part loose piece, in described comb
The correspondence position of plate body trapezoid boss is provided with the groove to match with the correspondence position of locating convex block II.
Oblique detent is provided with the middle part of the inclined-plane side of described left part loose piece and right part loose piece, in described comb
The medial slope of plate body is provided with the oblique projection being adapted with oblique detent correspondence position.
It is an advantage of the invention that：
The present invention opens trapezoid groove as a result of said structure, both ends loose piece and middle part loose piece bottom, this positive ladder
Connected in star is engaged with the trapezoid boss of grate plate body, and this cooperation makes the contact surface of protection loose piece and grate plate body larger,
Trapezoidal cooperation is also more convenient dismounting protection loose piece, the inclined-plane of end loose piece and the contact of incline plane of grate plate body, because loose piece is with combing
The contact surface increase of plate body, produces larger impulsive force and is disperseed, be so not in that contact surface abrasion speed is fast when broken
The phenomenon rocked with loose piece.The problem of prior art protection loose piece assembly difficulty is big is efficiently solved, is also solved due to connecing
The problem of small protection loose piece of contacting surface product rocks, extends the service life of loose piece；
2nd, the trapezoid of the trapezoid grafting groove and grate plate body of left part loose piece, right part loose piece and middle part loose piece is convex
Gap is left during platform grafting at plane, and by fastening bolt, clamp nut and is arranged between fastening bolt and clamp nut
Spring washer is fixedly connected, simple and convenient during replacing, is reduced repair and maintenance workload, is shortened the repair and maintenance time；
3rd, maintenance cost is reduced.
