Problems solved by technology

The advantages of polytetrafluoroethylene material are small friction coefficient and wear resistance, and the disadvantage is that the allowable compressive stress is low and the bearing capacity per unit area is small; The self-lubricating performance is poor, and there is a phenomenon of absorbing grease, which is highly dependent on the grease. Once there is no grease, it will heat up due to friction and bite under high pressure. After a period of use, silicon grease needs to be added to the support. Difficulty in maintaining

Abstract

The invention relates to a highly wear-resistant sliding plate for a support of a bridge building and an intelligent force measuring support. The sliding plate consists of a fluoroplastic alloy material circular plate of which the surface is provided with an oil storage groove, wherein a metallic framework circular plate is embedded into the fluoroplastic alloy material circular plate and is provided with a through hole; and the external surface of the metallic framework circular plate is coated with a metallic powder layer. The sliding plate integrates self-lubricating, highly wear-resistant, highly pressure-resistant and low-creep properties.

Description

technical field [0001] The invention relates to a support for bridge construction and a high wear-resistant slide plate for an intelligent force-measuring support. Background technique [0002] At present, the slide plates used for bridge bearings of roads, railways, urban rails and overpasses are made of polytetrafluoroethylene or modified ultra-high molecular weight polyethylene. Taking advantage of their small friction coefficient and wear resistance, they are mainly used in the bearings. Play the role of reducing wear. The advantages of polytetrafluoroethylene material are small friction coefficient and wear resistance, and the disadvantage is that the allowable compressive stress is low and the bearing capacity per unit area is small; The self-lubricating performance is poor, and there is a phenomenon of absorbing grease, which is highly dependent on the grease. Once there is no grease, it will heat up due to friction and bite under high pressure. After a period of use...
