Long-acting self-lubricating high-durability spherical support and lubricating method thereof

Abstract

The invention discloses a long-acting self-lubricating high-durability spherical support, and relates to the technical field of bridge structure design. The spherical support comprises a lower supportplate, an upper support plate and a spherical crown, the spherical sliding plate on the lower support plate is in contact with the lower surface of the spherical crown; through holes are formed in the spherical sliding plate and the plane sliding plate, and lubricants are arranged in the through holes; the lower support plate is connected with the concrete padstone; and the upper support plate isconnected with the concrete main beam. The lubricants are automatically supplemented, the lubricating effect of the lower support plate and the upper support plate is kept, it is guaranteed that thefriction coefficient of the spherical sliding plate and the friction coefficient of the plane sliding plate are stable, and therefore the sliding performance and the rotating performance of the support are guaranteed.

Problems solved by technology

[0002] At present, only a certain amount of silicone grease can be pre-stored in the grease storage tanks of the pot type and spherical bearing slides used in domestic and foreign bridge construction projects, and the silicone grease cannot be replenished later, resulting in a decrease in the silicone grease content of the bearings during long-term use. , the silicone grease is gradually concentrated, the lubricating effect decreases, and the wear of the skateboard increases

During the normal sliding and rotating process of conventional bearings, the silicone grease lubricant will inevitably be carried out and volatilized and consumed

After the silicone grease lubricant is missing, the sliding performance of the support decreases, the friction coefficient increases, and the wear of the slide plate also increases; as the number of bearing rotations increases, the silicone grease lubricant will continue to be attached to the spherical steel liner, gradually Loss, wear, decreasing lubricity

The silicone grease lubricant of the support is continuously reduced, and the friction coefficient of the slide plate is continuously increased, which will increase the wear of the slide plate, and the slide plate cannot meet the life requirement of the support, thus affecting the service life of the support; the silicone grease lubricant of the support is continuously reduced , the friction coefficient of the sliding plate keeps increasing, and the displacement or rotation function of the support is blocked. Not only can it not adapt to the deformation of the bridge, but prevent the deformation of the bridge, it will seriously affect the stress state of the bridge and the normal operation of the line, and make the life of the bridge bear the risk.
