Bridge spherical steel support used in severe cold area
The invention discloses a bridge spherical steel support for severe cold areas, which is characterized in that the upper end of an upper support plate is connected with an upper bridge through an upper connecting piece, the interior of the bottom end surface of the upper support plate is connected with the upper end surface of a lining plate through a first wear-resisting plate, and the lower end surface of the lining plate is connected with the upper end surface of a second wear-resisting plate; the lower end face of the second wear-resisting plate is connected with the upper end face of a lower support plate, and the lower end of the lower support plate is connected with a lower bridge through a lower connecting piece. The first wear-resisting plate and the second wear-resisting plate are modified ultra-high molecular weight polyethylene wear-resisting plates, so that the plates have the advantages of high bearing capacity, good self-lubricating performance, creep resistance and low temperature resistance, and are suitable for working environments with heavy load, large displacement and high-speed movement; the upper support plate and the lower support plate are respectively made of hot-rolled low-alloy structural steel plates and have durability, so that the support can meet the durability requirement that the service life of the support is the same as that of a bridge main body under normal maintenance, and the support has the advantages of simple and reliable structure, uniform spherical force transmission, large rotation angle and aging resistance.
本发明公开了一种用于严寒地区的桥梁球形钢支座，在上支座板上端通过上连接件联接有上部桥梁，上支座板底端面内部通过第一耐磨板与衬板的上端面联接，衬板的下端面与第二耐磨板的上端面联接，第二耐磨板的下端面与下支座板的上端面联接，下支座板的下端通过下连接件联接有下部桥梁。本发明通过第一耐磨板、第二耐磨板分别为改性超高分子量聚乙烯耐磨板，具有承载能力高、自润滑性能好、抗蠕变、耐低温性的优点，适应于重载、位移量大和高速运动的工作环境；上支座板、下支座板分别为热轧低合金结构钢板材，具有耐久性，使支座在正常维护下可达到与桥梁主体同寿命的耐久性要求，本发明具有结构简单可靠、球面传力均匀、转动角度大、耐老化优点。
