Problems solved by technology
However, due to the huge size of the bridge, when it rotates, it will cause great wear and tear on the fulcrum, which will cause damage to the support. Moreover, the resistance will be extremely large during rotation, and at the same time, it will also cause damage to the rotating bearing, especially the bridge When the center of the bearing is not on the central axis of the support, it is easy to cause damage to the support and even cause danger

The invention discloses a swivel bearing used for bridge construction. By setting a rotating support ring seat, the supporting capacity during rotation can be improved. A ring-shaped hydraulic oil film cavity is provided, and the oil film is used for floating support, which can improve the supporting capacity. The specific pressure of the oil film can be controlled by the pressure control valve in the oil flow channel, so that the replacement of the oil film can be effectively realized and the improvement can be improved. Supporting capacity, the cavity depth of the connection between the hydraulic oil film cavity and the hydraulic oil supply mechanism of the present invention is far away from the cavity depth of the connection, so that the hydraulic oil film in the hydraulic oil film cavity is in the shape of a cross section on a vertical plane Wedge shape, and then use the hydraulic oil film to realize the oil film floating support for the rotating support ring seat.
Description
technical field [0001] The invention specifically relates to a swivel support used for bridge construction, and belongs to the technical field of building construction. Background technique [0002] In the process of building construction, for the construction of bridges, at present, bridges are generally processed and manufactured in production workshops or special bridge production managers, and then the bridges are directly assembled or assembled on site. Therefore, when assembling or assembling, a rotatable support is often required to support and rotate the bridge so as to realize installation at a required angle. However, due to the huge size of the bridge, when it rotates, it will cause great wear and tear on the fulcrum, which will cause damage to the support. Moreover, the resistance will be extremely large during rotation, and at the same time, it will also cause damage to the rotating bearing, especially the bridge When the center of the bearing is not on the cen...
