Problems solved by technology

The steel wear plate is welded and fixed on the coupler frame support plate. The coupler frame support plate is installed behind the car body. The steel wear plate is in direct contact with the coupler frame. During the driving process of the truck, it will be worn due to various reasons such as vibration. Due to the direct wear of the plate, it is difficult to replace the wear plate after it is worn out. Since the wear plate is welded and fixed on the support plate of the coupler frame, the weld seam must be cut off after the wear plate wears to the limit, which is easy to cause damage to the support plate body of the coupler frame

Abstract

The invention discloses a hook-and-tail frame pallet wear plate, which is a composite structure. The engineering plastic is used as a substrate, and an adhesive layer is arranged on the outer surface of the substrate. The outer surface of the adhesive layer is provided with a wear layer. The engineering plastic as the substrate has high hardness, strength and other good performance, in order to better improve the wear resistance, the engineering plastic surface is made into the rough surface by shot blasting process and brushing the adhesive layer. The adhesive layer is made of polymer-based composite materials, in which ceramic particles are added. On the one hand the bonding with the substrate is guaranteed; on the other hand, the adhesive layer can be well combined with the wear-resistant layer on the outer surface to ensure that the wear-resistant layer is firmly set on the outer surface of the hook-and-tail frame pallet wear plate.

Description

technical field [0001] The invention relates to an accessory of a railway transport vehicle, in particular to a wearing plate of a coupler frame support plate with wear resistance. Background technique [0002] Railway wagons are equipped with coupler frames, which are supported by pallets. In order to protect the coupler frames from wear and tear, the relevant regulations specify that the drag plates supporting the coupler frames must be equipped with wear plates. A3 ordinary steel plates are used, and the remaining wear plates are Replace when the thickness is less than 50%, and can be directly welded on the carriage of the coupler frame. The steel wear plate is welded and fixed on the coupler frame support plate. The coupler frame support plate is installed behind the car body. The steel wear plate is in direct contact with the coupler frame. During the driving process of the truck, it will be worn due to various reasons such as vibration. Due to the direct wear of the p...
