Abstract
The utility model relates to an abrasion-proof groove side for the middle of the scraping plate conveyor, and comprises the groove side connected with the two terminals of the middle plate. The upper and the lower grooves of the groove side are welded with a plurality of abrasion-proof alloy bars. The top surface of the upper groove and the top and the bottom sides of the lower groove are welded together and only limitedly positioned in the inlet of the both sides of the groove side. The abrasion-proof alloy bar welded in the bottom face of the groove on the groove aid is running throughout the whole groove side. The abrasion-proof alloy bars welded in the top surface of the upper groove and the top and the bottom surface of the lower groove is limited to the inlet of two terminals of the groove side. The welded abrasion-proof alloy bar and the abrasion-proof alloy cross section can be round, and also can be quadrate. Through the welding abrasion-proof alloy bar, the utility model can effectively improve the durability of the groove part of the middle groove side, reduce the abrasion of the scraping plate to the groove side, and thus effectively improve the use life-span of the high and middle groove. The utility model is applicable to the scraping plate transport in the mine under well for groove aid of the transition groove, with simple structure and low cost, excellent durable effect and a wide range of application.
Description
Technical field
The utility model relates to the wear-resisting ledge of The middle pan of scraper conveyor, is particularly useful for plate, transitional slot ledge in the slat conveyer of down-hole, mine.
Background technology
China's The middle pan of scraper conveyor ledge material is 20MnTi or 16Mn steel mostly, and this steel has weldability preferably, but resistance to abrasion, corrosion stability are poor.Because the environment under the mine is abominable, intermediate channel is difficult for keeping abswolute level putting of down-hole, and the degree of wear of scraper plate centering board slot group is very big, and especially the wearing and tearing of the interface of ledge are very serious, if only start with from the material that improves the intermediate channel ledge, its cost is higher.
Summary of the invention
Technical matters: the purpose of this utility model provides the wear-resisting ledge of a kind of simple in structure, cheap, effective The middle pan of scraper conveyor.
Technical scheme: the wear-resisting ledge of the utility model The middle pan of scraper conveyor, it comprises the ledge that is connected middle plate two ends, two interior built-up welding of groove up and down of described ledge have many abrasion resistant alloy bars.
The wear-resisting ledge of the utility model The middle pan of scraper conveyor, the abrasion resistant alloy bar built-up welding of described ledge upper groove bottom surface runs through whole ledge; The abrasion resistant alloy bar built-up welding of upper groove end face and low groove end face and bottom surface only limits to the entrance at ledge two ends; The abrasion resistant alloy bar of described built-up welding and wear-resisting alloy block cross-sectional plane can be circular arc, also can be square.
Technique effect: the wear-resisting ledge of the utility model The middle pan of scraper conveyor is particularly useful for plate, transitional slot ledge in the slat conveyer of down-hole, mine.On the basis that does not change former intermediate channel ledge material and manufacturing process, employing has many abrasion resistant alloy bars by definite shape, size, size built-up welding in the low groove on ledge scraper plate process, it can improve the resistance to abrasion at intermediate channel ledge groove position effectively, reduce the wearing and tearing of scraper plate to ledge, thereby improve the service life of intermediate channel effectively, it is simple in structure, cost is low, and is wear-resisting effective, has practicality widely.
Description of drawings:
Accompanying drawing is the wear-resisting ledge constructional drawing of the utility model The middle pan of scraper conveyor.
Among the figure: 1-ledge, 2-alloy bar, plate among the 3-.
The specific embodiment
Below in conjunction with accompanying drawing an embodiment of the present utility model is further described:
The wear-resisting ledge of the utility model The middle pan of scraper conveyor, shown in the accompanying drawing, on ledge 1 that original The middle pan of scraper conveyor matches with scraper plate in the low groove, move towards many abrasion resistant alloy bars 2 of built-up welding,, reduce the wearing and tearing of scraper plate to ledge 1 to strengthen the resistance to abrasion of ledge 1 along scraper plate.During concrete enforcement, run through whole ledge at the abrasion resistant alloy bar 2 of the upper groove bottom surface built-up welding of ledge 1; The abrasion resistant alloy bar 2 of upper groove end face and low groove end face and bottom surface built-up welding only limits to the entrance at ledge 1 two ends; The cross-sectional plane of the abrasion resistant alloy bar 2 of built-up welding can be a circular arc, also can be square.
Claims (3)
1. the wear-resisting ledge of The middle pan of scraper conveyor, it comprises the ledge (1) that is connected middle plate (3) two ends, it is characterized in that: built-up welding has many abrasion resistant alloy bars (2) in two grooves up and down of described ledge (1).
2. the wear-resisting ledge of The middle pan of scraper conveyor according to claim 1 is characterized in that: abrasion resistant alloy bar (2) built-up welding of described ledge (1) upper groove bottom surface runs through whole ledge; Abrasion resistant alloy bar (2) built-up welding of upper groove end face and low groove end face and bottom surface only limits to the entrance at ledge (1) two ends.
3. the wear-resisting ledge of The middle pan of scraper conveyor according to claim 1 is characterized in that: the abrasion resistant alloy bar (2) of described built-up welding and wear-resisting alloy block (4) cross-sectional plane can be circular arc, also can be square.
