Abstract

The invention relates to a high-strength bridge support seat sliding plate for a high-speed rail. The bridge support seat sliding plate comprises a round-structure lining plate and an oil storage tank set arranged on the lining plate. The oil storage tank set comprises two first oil tank sets, two second oil tank sets, two third oil tank sets and a fourth oil tank set. The fourth oil tank set comprises seven oil tanks. The linking line of circle centers of the seven oil tanks of the fourth oil tank set coincides with the diameter of the lining plate. Each third oil tank set comprises six oil tanks. Each second oil tank set comprises five oil tanks. Each first oil tank set comprises four oil tanks. The first oil tank sets, the second oil tank sets and the third oil tank sets are arranged on the two sides of the fourth oil tank set correspondingly and symmetrically. The oil tanks of every two adjacent oil tank sets are arranged in a staggered mode. Compressive strength is high, supporting ability is high, and service life is prolonged effectively. A special composition formula is adopted, and through a specially prepared formula of lubricant and a solubilizer, self-lubricating performance and abrasion resistance of the bridge support seat sliding plate can be improved greatly.

Description

Technical field [0001] The invention relates to a bearing slide plate, in particular to a high-strength bridge bearing slide plate for high-speed rail. Background technique [0002] With the development of industry and the acceleration of the pace of life, the construction of railway passenger dedicated lines will also increase. In order to reduce the amount of land occupied, most railway passenger dedicated lines adopt the way of viaducts. In this way, the use of bridge bearings is greatly increased. In the architectural design of highway and railway bridges, prefabricated bridges are usually placed on the piers. The bridges and piers are in a floating state, and their bearings will bear huge dynamic loads, that is, the bearings will not only bear huge positive pressure In addition, it also withstands slight lateral movement. The traditional structure uses a high-strength spherical body as a support, but the specific pressure will be large, and the support will be difficult to ...
