Abstract
The utility model relates to a wear -resisting medium plate in scraper conveyor middle part groove. Including medium plate body (1), its characteristics are: it has a plurality of recesses that are parallel to each other to open on the upper surface of medium plate body (1) to institute's notched orientation is all parallel with the traffic direction of scraper chain. Through identification on probation, the utility model discloses with the medium plate design convex and concave groove for amplitudes such as different period natures, it has increased the medium plate and has shortened convex and concave groove variation period promptly with scraper chain contact department convex and concave groove density to make pointed references, strengthens improving the local wearability of medium plate, has solved scraper chain that all middle part groove in use appear and has said the serious problem of wearing and tearing. The convex and concave groove structure of medium plate upper surface can improve medium plate mechanical strength to whole middle part groove in addition, is favorable to metal liquid flow, cooling in the casting forming process, takes shape, has reduced casting stress. Simultaneously also can reduce the casting cost.
Description
Technical field
The utility model is related to a kind of the middle pan of scraper conveyor wear-resistant middle plate.
Background technology
The conveying equipment of underground coal mine fully mechanized mining in recent years is increasingly intended to high-power, big groove width equipment, in drag conveyor
Used as scrapper conveyor major critical component, its life-span directly influences machine life to portion's groove.Current intermediate channel is mostly by casting baffle plate
The Combination Welding such as plate, base plate and rack rails seat is formed in ledge, casting shovel board ledge, high-strength abrasion-proof plate, and another one into
The intermediate channel of type welding, i.e., including baffle, shovel board ledge, rack rails seat, middle plate, the disposable monoblock cast of back cover plate and
Into.
But still without plate upper surface in scraper plate abrasion of chain is solved the problems, such as very well, plate upper surface is in existing intermediate channel
Planar structure, scraper chain and the big plane contact of whole middle plate, contact area is big, frictional resistance is also big, causes whole middle plate abrasion
Aggravation, especially scraper chain and the position that the abrasion of middle plate operation area is whole middle plate abrasion most serious, in middle plate structure design
In be not different and treat.
Utility model content
The purpose of this utility model is to provide a kind of the middle pan of scraper conveyor wear-resistant middle plate, can be by periodicity etc.
Hardened structure strengthens the wearability of plate in intermediate channel in amplitude crossheading shape, and then improves the bulk life time of intermediate channel.
A kind of the middle pan of scraper conveyor wear-resistant middle plate, including middle plate body, it is particular in that：In the middle plate sheet
Be provided with some grooves being parallel to each other on the upper surface of body, and reeded direction put down with the traffic direction of scraper chain
OK.
The depth of its further groove is 3~8mm.
Circular arc chamfering is between the upper surface of the both sides of its further groove and middle plate body.
Its further groove uses V-groove or U-type groove.
For compact district, other regions are common with the region of scraper chain contact position wherein on the upper surface of middle plate body
Area, the spacing of adjacent grooves is 1/2~3/4 of adjacent grooves spacing in general area in the compact district.
Test proves that, middle plate is designed as the utility model the convex-concave groove of the amplitudes such as different cycles, targetedly
Increased middle plate and scraper chain contact position convex-concave groove density and shorten convex-concave groove period of change, plate is locally wear-resisting in strengthening improvement
Property, solve the problems, such as the scraper chain road serious wear that all intermediate channels occur in use.The convex-concave of plate upper surface in addition
Slot structure, plate mechanical strength in being improved for overall intermediate channel, be conducive to during casting Liquid-metal flow,
Cooling, shaping, reduce casting stress.Can also reduce casting cost simultaneously.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model.
Specific embodiment
As shown in figure 1, the utility model provides a kind of the middle pan of scraper conveyor wear-resistant middle plate, including middle plate body 1,
It is provided with some grooves being parallel to each other on the upper surface of the middle plate body 1, and the reeded direction of institute is and scraper chain
Traffic direction it is parallel.
The depth of its further groove is 3~8mm, is circular arc between the both sides of groove and the upper surface of middle plate body 1 and falls
Angle, and groove uses V-groove or U-type groove.Other is close with the region of scraper chain contact position on the upper surface of middle plate body 1
Ji Qu (at two A in Fig. 1) and other regions are general area, during the spacing of adjacent Baltimore groove is general area in the compact district
The 1/2~3/4 of the spacing of adjacent Baltimore groove.
It is in the amplitude crossheading shape intermediate channel wear-resistant middle plates such as periodicity that the utility model is provided a kind of, and plate body can use in this
Cast steel wear resistant alloy material is integral with scraper conveyor middle groove design, and integrated poured to form, the middle plate body of the shape can also lead to
Cross mould rolling and form wear-resisting steel plate, for welding structure intermediate channel.
The upper surface that middle plate body of the present utility model is contacted with scraper chain uses waits amplitude shape convex in periodic distribution
Groove structure, to alleviate abrasion of the scraper chain to plate in intermediate channel, enhancing is integrally formed the performance of middle part slot structure.Convex-concave groove with
Scraper chain traffic direction is in the amplitude regular distributions such as periodicity in parallel arrangement, cross section uneven arrangement.Convex-concave groove is transversal
EDS maps determine the closeness of arrangement, the convex-concave groove of scraper chain operation area according to scrapper conveyor scraper chain spacing and scraper chain specification
Arrangement period is 1/2~3/4 times or so of other regions.Convex-concave 3~8mm of groove depth, convex-concave groove depth and groove width and chain rules and regulations
Lattice size is relevant.
