Abstract
The utility model relates to a scraper conveyer groove upper. The groove upper comprises a shovel upper and a baffle upper which are arranged in opposite directions, wherein the opposite end surfaces of the shovel upper and the baffle upper are designed into an arch shape, an upper inward recessed part and a lower inward recessed part of the arch shape are plate accommodating cavities, an inner wear-resistant layer is fixedly connected with the upper inclined surface of the upper plate accommodating cavity, and an outer wear-resistant layer is fixedly connected on the top plane of the shovel upper, and the outer wear-resistant layer and the inner wear-resistant layer are wear-resistant steel plates which are welded on the groove upper. In the technical scheme, because the inner wear-resistant layer is arranged in the upper inclined surface of the plate accommodating cavities, the fracture caused by scraper abrasion is prevented, simultaneously, the abrasion of a piston shoe of a coal mining machine is prevented by the outer wear-resistant layer arranged on the shovel upper, and the service life of the groove upper is greatly prolonged.
Description
Technical field
The utility model relates to a kind of colliery underground equipment, especially mines with the ledge of drag conveyor.
Background technology
In present down-hole coal excavation process, the drag conveyor that coal mine fully-mechanized mining working uses is cast-welded, and promptly the ledge steel is a foundry goods, and middle plate, back cover plate are steel plate.Ledge is divided into shovel group and retaining group according to the position with respect to work plane.Drag conveyor not only transports coal, or the walking track of coal-winning machine, the strong point of preceding moving hydraulic support, ledge inner surface and coal cinder, spoil, scraper plate friction, shovel is helped surface and the friction of coal-winning machine piston shoes, because ledge is a foundry goods, abrasion resistance is relatively poor, and it is very fast to wear and tear, have a strong impact on the application life of drag conveyor, increased maintenance workload.Though can adopt the high wearing plate of hardness to make ledge, processing difficulties ruptures when bending easily.
The utility model content
The purpose of this utility model provides the good scratch board conveyor ledge of a kind of anti-wear performance.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of scratch board conveyor ledge, ledge comprises shovel group and the retaining group that arranges in opposite directions, shovel group and retaining are helped in opposite directions, and end face is designed to arc, arc upper and lower two places of caving in are for holding the plate chamber, it is characterized in that: the ramp in last appearance plate chamber is fixedly connected with interior wearing layer, is fixedly connected with outer wear layer on shovel group top plan.
Above-mentioned a kind of scratch board conveyor ledge is characterized in that: outer wear layer, interior wearing layer material are wear-resisting steel plate, and they are welded on the ledge.
Owing to hold the interior wearing layer of installation in the ramp of plate chamber, prevent to produce fracture in the such scheme because of the scraper plate wearing and tearing; Simultaneously, the outer wear layer that shovel is helped has prevented the wearing and tearing of coal-winning machine piston shoes, has prolonged the application life of ledge greatly.
The utility model is further described below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure 1, ledge 2, outer wear layer 3, interior wearing layer 4, middle plate 5, scraper plate
The specific embodiment
As shown in Figure 1, a kind of scratch board conveyor ledge, ledge 1 comprises shovel group and the retaining group that arranges in opposite directions, shovel group and retaining are helped in opposite directions, and end face is designed to arc, arc upper and lower two places of caving in are for holding the plate chamber, wearing layer 3 in the ramp in last appearance plate chamber is fixedly connected with is fixedly connected with outer wear layer 2 on shovel group top plan.Outer wear layer 2, interior wearing layer 3 materials are wear-resisting steel plate, and they are welded on the ledge 1.
