Swivel support for bridge construction
The invention discloses a swivel support for bridge construction. A rotary supporting ring seat is arranged to improve the supporting capacity during rotation, an annular hydraulic oil film cavity isformed between the bottom wall of the rotary supporting ring seat and the inner wall in a supporting disc, floating support is carried out in an oil film manner to improve the supporting capacity, andspecifically, the pressure of the oil film can be controlled by a pressure control valve in an oil receiving flow channel, so the replacement of the oil film can be effectively realized, and the support capability is improved. The cavity depth of the connecting position of the hydraulic oil film cavity and a hydraulic oil supply mechanism is far away from the cavity depth of the connecting position, so that the hydraulic oil film in the hydraulic oil film cavity is in a wedge shape on the cross section of the vertical plane, and then oil film floating supporting of the rotary supporting ringbase is achieved through the hydraulic oil film.
本发明公开了一种用于桥梁施工的转体支座，其通过设置旋转支撑环座，可以提高旋转时的支撑能力，同时旋转支撑环座的底壁与所述支撑盘内的内壁之间设置有环形的液压油膜腔，利用油膜的方式进行浮动支撑，可以提高支撑能力，具体油膜的压力大小可以由接油流道内的压力控制阀进行控制，这样，可以有效的实现油膜的更换，提高支撑能力，本发明的液压油膜腔与所述液压油供给机构的连接处的腔体深度远离开连接处的腔体深度，以便使得液压油膜腔内的液压油膜在竖直平面的横截面上呈楔形形状，进而利用所述液压油膜实现对所述旋转支撑环座的油膜浮动支撑。
