Method for supplementing lubricating agent to curved steel support seat and curved steel support seat matched with same

Abstract

The invention discloses a method for supplementing a lubricating agent to a curved steel support seat and the curved steel support seat matched with the same, overcoming the technical defects that the traditional bridge curved steel support seat has no function of supplementing the lubricating agent. The key point in the invention is to solve problems of the self lubrication and lubricating agent loss between a convex curved upper lining plate and a concave curved sliding plate, thus the method and the curved steel support seat matched with the same are technically and crucially characterized in that silicon grease lubricating agents are pre-stored in a vertically-arranged grease discharging hole canal and a grease storage through groove; when the support seat works, the convex curved upper lining plate and the concave curved sliding plate are subjected to friction to disperse stress, so that the silicon grease lubricating agent in the grease storage through groove is lost due to long-term friction; the silicon grease lubricating agents pre-stored in the vertical grease discharging hole canal can be continuously filled in the grease storage through groove due to gravity action, thus the silicon grease lubricating agent lost in the grease storage through groove is supplemented, the aim of lubricating a spherical friction pair for a long term is achieved and the service life of the support seat is prolonged.

Description

technical field [0001] The invention relates to the field of bridge erection, which is a curved steel support with a pre-stored silicone grease tank, and specially designs a method for replenishing lubricant for the curved steel support and the matching curved steel support. Background technique [0002] Bridge bearings are key components in bridge structures. It can reliably transmit the reaction force and deformation of the bridge superstructure to the bridge substructure. Therefore, the bridge support must have sufficient bearing capacity to ensure the safe and reliable transmission of the support reaction force. Secondly, the support should restrain the bridge deformation as much as possible. As small as possible, it has adapted to the free expansion and contraction of the beam body and the flexible rotation. The existing bridge curved steel bearing is mainly composed of an upper bearing plate, a convex curved steel lining plate, a plane sliding pair located between the...
