Abstract
The utility model relates to the technical field of scraper conveyers for coal mines, particularly to a combined mold forging rail base. With the continuous improvement of the production capacity of coal manufacturing enterprises, scraper conveyers with high power and high reliability become required coal exploitation equipment. A rail seat used as one of main component parts of a middle groove is required to have compact structure and improved strength, rigidity, reliability and service life. The utility model has the technical scheme that an upright surface with a round hole of a bent plate is positioned on the long round hole side of a rail seat body to form a left and right combined mold forging rail base; a supporting block is welded on the inner right angle of the bent plate and the rail seat body. A surface A with a hole in a cavity of the rail seat body is a plane which is vertical to the central line for connecting holes. A B surface is a positioning and supporting surface for the rail seat body and a forging pin rail and is connected through a fixed pin. A lateral pin passes through a circular arc slot of the fixed pin to fix the forging pin rail. The utility model is suitable for matching forging pin rails for use.
Description
One, technical field
The utility model relates to colliery slat conveyer technical field, it is the main constituent elements of The middle pan of scraper conveyor, it is welded on the two ends of the baffle plate ledge side of conveyer intermediate channel, be used for installing and the set pin rail, drive a kind of specifically combined die forging rail chair with the engagement walking that realizes pin rail and coalcutter.
Two, background technology
Present homemade The middle pan of scraper conveyor adopts the inblock cast structure with the rail chair major part.Along with the production intensity of coal production enterprise improves constantly, high-power, high reliability slat conveyer becomes indispensable coal mining equipment, intensity, reliability and the life-span of slat conveyer critical component intermediate channel must improve, rail chair as one of main constituent elements of intermediate channel, also require its structure compact more, intensity, rigidity, reliability and life-span must further improve.Because the rail chair profile is less relatively, all good solid forging type pin rail of rigidity, intensity and the life-span of supporting installation comes out with it simultaneously.Therefore, if rail chair by foundry technique manufacturing in the past, just be difficult to satisfy the needs that the highly efficient and productive mine intensification in colliery is produced aspect integral rigidity, intensity, reliability and life-span, severe wear in use appears easily, even the situation of generation fracture, the operating needs that this obviously can't satisfy the user has a strong impact on the production efficiency of coal production enterprise.
Three, summary of the invention
The purpose of this utility model provides a kind of combined die forging rail chair, and this rail chair can guarantee the supporting use with novel forged pins rail, and its integral rigidity, intensity and resistance to abrasion can satisfy requirement high-power, the high reliability slat conveyer.
The technical solution of the utility model is: the band circular hole facade of bent plate is positioned at the slotted hole side of rail chair body, forms left and right combined die forging rail chair; Back-up block is welded in the place, interior right angle of bent plate and rail chair body, and it is a line of centers that the center line separately of rail chair body, back-up block and bent plate overlaps; Endoceliac with holes the A of rail chair is the plane vertical with the connection holes line of centers, and forge the inclined-plane accordingly with the forged pins rail and leave the gap, the B face is rail chair body and forged pins rail positioning supports face, by set pin it is connected, pass the circular arc ditch of set pin again with lateral pin, the forged pins rail is fixed.
Rail chair body of the present utility model adopts the high-quality alloy steel that can heat-treat reinforcement, adopt the mould Forging Technology, finish manufacturing process through the whole forging forming of matched moulds, side cut, punching and follow-up heat treatment step, improve the rail chair body reliability of service and the purpose in wear-resistant life-span thereby reach.Rail chair chaeta base is the symmetric form structure, its mucosal structure guarantees position accuracy demand by die size, there is brace rod to connect in the middle of in the chamber, outside and technologies such as surface of internal cavity, circular hole and slotted hole by processing rail chair body, make it form the left and right sides rail chair body of symmetrical configuration, wherein the circular hole of left and right sides rail chair body is used for being fixedly connected of the sold inside the country rail of intermediate channel, and slotted hole is used for the adjustment cross-over connection of pin rail between intermediate channel; Rail chair intracoelomic cavity surface with holes, the left and right sides all is processed as the equidistant plane vertical with centerline hole, locatees with reliable thereby satisfied with the correct installation of pin rail, provides technical guarantee for supporting high-intensity novel forged pins rail simultaneously.Bent plate and back-up block shape respectively, with the combined die forging rail chair in the left and right sides of left and right sides rail chair body difference assembly welding formation symmetrical configuration.
The beneficial effects of the utility model are, rail chair body material is closely knit, integral rigidity and intensity height, resistance to abrasion and Dent resistance are good, the life-span is high, overcome that conventional cast rail chair structure precision is low, the shortcoming of undercapacity, poor reliability, serious wear, low, easy fracture of life-span, for use high-power, the high reliability slat conveyer provides technical guarantee.
