Problems solved by technology

Traditional single-metal wear-resistant plates have poor wear resistance, while other bi-metal composite plates such as surfacing wear-resistant metal materials have complicated manufacturing processes and high costs, and the wear of the chain is aggravated during use, which needs to be improved

Embodiment Construction

[0010] Such as figure 1 , figure 2 The plate in the groove shown in the middle (an example of a composite wear-resistant plate) includes a wear-resistant plate substrate 1 and a polyurethane wear-resistant layer 2 . The material of the base plate is Hardox450 wear-resistant plate with a thickness of 40mm; dovetail grooves are processed on the working surface of the base plate at the chain path (that is, the most seriously worn part of the middle plate). The urethane wear-resistant layer is cast in the form of hot fluid in the base plate embedding groove, and the pouring temperature is 250-300°C.

Abstract

The invention belongs to the technical field of wear-resisting plates applied to middle troughs of scraper conveyers of coal mines and particularly relates to a composite wear-resisting plate. The wear-resisting plate comprises a base plate and a wear-resisting layer embedded onto the base plate. The base plate is a wear-resisting plate which is made from polyurethane; an embedding groove is formed in the local part of a work face of the base plate of the wear-resisting plate; and wear-resisting polyurethane is poured into the embedding groove in the form of a thermal state liquid. The composite wear-resisting plate is good in wear-resisting performance, relatively high connection strength between the base plate and the wear-resisting layer is ensured due to the embedding structure, and the manufacturing process is relatively simple.

Description

technical field [0001] The invention belongs to the technical field of wear-resistant plates applied to the middle groove of coal mine scraper conveyors, in particular to a composite wear-resistant plate. Background technique [0002] Coal mine scraper conveyors work under harsh underground conditions, and the middle trough is the load-bearing part of the material. It is the main body of the conveyor in terms of volume and weight, and is the most used and consumed part. When the conveyor is working, the scraper chain drives the scraper to run along the middle groove. In addition to the wear of the middle plate and the bottom plate, the scraper chain and the scraper will aggravate the wear of materials such as coal and gangue, so the scraper conveyor The failure is mostly caused by the excessive wear of the middle and bottom plates of the middle groove, and the wear of the middle and bottom plates is especially serious at the chain path. Traditional single-metal wear-resista...
