Description

Technical Field

[0001] The utility model relates to the field of bridge engineering, in particular to a bridge bearing slide plate with long-term self-lubricating performance, which adopts plastic body oil lubrication composed of an oil-saturated polymer matrix to solve the problems of increased frictional resistance, accelerated wear of the slide plate and reduced durability caused by the loss of silicone grease in existing bridge bearings. Background Art

[0002] In a bridge structure, a bridge bearing is a key component connecting the bridge and the bridge pier. It not only needs to bear the weight of the bridge, but also needs to adapt to the displacement of the bridge caused by factors such as temperature, wind load, and earthquake. Traditional bridge bearing slide plates mostly use silicone grease for lubrication. Over time, the silicone grease will gradually be lost, especially in harsh environments, such as earthquake-prone areas or cross-sea bridges, where the loss of silicone grease will be aggravated. When the silicone grease is exhausted, the friction coefficient will increase, which may lead to an increase in the frictional resistance of the bearing, accelerate the wear of the slide plate surface, and may affect the overall flexibility of the bearing. Even if the silicone grease is regularly inspected and replenished, this not only increases the maintenance workload, but also may increase the frequency and cost of replacing the slide plate, and the lost lubricating grease will also cause environmental pollution, and even make maintenance difficult due to aerial work. At the same time, with the development of society, higher standards have been put forward for railway and highway construction. For harsh environmental conditions such as earthquake-prone areas and cross-sea bridges, friction pendulum isolation bearings need to be used. The design requirements of friction pendulum isolation bearings are that the slide plate should operate without silicone grease, and the friction coefficient should be controlled within a certain range. Therefore, it is particularly important to develop a new type of bridge bearing slide plate that can provide persistent lubrication and is heat-resistant and cold-resistant. Summary of the Utility Model

[0003] Aiming at the deficiencies of the existing technology, the utility model provides a new type of bridge bearing slide plate. The bridge bearing slide plate uses plastic body oil composed of an oil-saturated polymer matrix as a lubricating medium; it can operate stably under high load and extreme temperature conditions, automatically release lubricating oil during operation, thus significantly reducing maintenance requirements, reducing frictional losses, enhancing service life, and achieving maintenance-free persistent lubrication.

[0004] To achieve the above object, the utility model adopts the following technical solutions:

[0005] A new type of bridge bearing slide plate includes a slide plate body and a lubricating body; the slide plate body constitutes the basic structure of the slide plate to bear the weight of the bridge, and the material is divided into metal material and non-metal material. The slide plate body includes a flat slide plate; the lubricating body is a solid lubricating medium containing oil and having pores, composed of an oil-saturated polymer matrix, abbreviated as plastic body oil; holes or grooves are drilled or cut on the slide plate body, and the plastic body oil is filled in the holes or grooves to play a role in persistent lubrication, leakage prevention, and maintenance-free.

[0006] As a further solution of the present utility model, the skateboard body further includes a spherical skateboard; the structural form of the skateboard matches the structure of the bridge bearing. The material can be divided into metal material, non-metal material, or a composite material of metal and non-metal.

[0007] As a further solution of the present utility model, the skateboard body further includes a side skateboard, the structural form of which matches the structure of the bridge bearing, and the material is divided into metal material, non-metal material, or a composite material of metal and non-metal; the side skateboard is located on the side of the flat skateboard.

[0008] As a further solution of the present utility model, the flat skateboard includes: square, circular, fan-shaped, oval, polygonal, irregular shape, etc., without limitation.

[0009] As a further solution of the present utility model, the spherical skateboard includes: spherical, ellipsoidal, shell spherical, spherical crown, spherical frustum, etc., without limitation.

[0010] As a further solution of the present utility model, the side skateboard includes: strip-shaped, belt-shaped, flanged, semi-circular, irregular shape, etc., without limitation.

The cross-sectional forms of the grooves are: rectangular, arc-shaped, T-shaped, dovetail-shaped, and triangular. Plastic oil is filled in the grooves, and the excellent wear resistance and self-lubricating properties of the plastic oil are utilized to maintain a good lubrication state for a long time, thereby achieving a maintenance-free effect.

9. A novel bridge bearing slide plate as claimed in claim 1, characterized in that: The lubricating body uses plastic oil as a lubricating medium. Plastic oil is a high-molecular polymer material with special lubricating properties. Saturated lubricating oil is adsorbed inside. During movement, the lubricating oil moves to the surface of the friction pair under the action of capillary action to form a lubricating oil film. When the movement stops, the lubricating oil will be re-absorbed into the polymer and stored.

10. A novel bridge bearing slide plate as claimed in claim 1, characterized in that: The plastic oil is made of polyethylene PE, ultra-high molecular weight polyethylene, polyimide or PEEK polymer as a base material, and is mixed with lubricating oil and additives to form a viscous fluid lubricating medium. After being injected into the skateboard body by injection molding, molding, and vulcanization, it is heated and cured to form a porous oil-containing lubricating material. These micropores can accommodate the lubricating oil and retain it in the material through surface tension.
