UHPC bridge expansion device with adjustable height
The invention relates to the technical field of bridges, in particular to a height-adjustable UHPC bridge expansion device which comprises a bearing support and a concrete layer, the bearing support is integrally composed of a connecting transverse frame, a bearing support, a center truss, a supporting support and an extending support, and the bearing support is provided with a first supporting mechanism used for supporting the concrete layer through a driving worm. The bearing support is provided with a second supporting mechanism used for supporting the concrete layer through a ball screw. The connecting transverse frame, the bearing support, the center truss, the corresponding support and the extending support form the bearing support, so that a concrete layer can be movably supported on the bearing support; a supporting effect is provided for the concrete layer from the two side positions; the ball screw integrally connected with the driving worm is arranged, and the lifting nut moving up and down is arranged through the ball screw, so that traction driving is conducted on the steering lever, and an auxiliary supporting effect is provided for a concrete layer from the middle position.
本发明涉及桥梁技术领域，尤其涉及高度可调的UHPC桥梁伸缩装置，包括承载支架与混凝土层，所述承载支架由衔接横架、承重支架、中心桁架、策应支架与延伸支架一体组成，所述承载支架通过驱动蜗杆设置有用于支撑混凝土层的第一支撑机构，且承载支架通过滚珠丝杆设置有用于支撑混凝土层的第二支撑机构。本发明利用衔接横架、承重支架、中心桁架、策应支架与延伸支架组成承载支架，以便于在承载支架上对混凝土层进行活动支撑；以便于从两侧位置为混凝土层提供支撑作用；通过设置与驱动蜗杆一体连接的滚珠丝杆，利用滚珠丝杆设置上下移动的升降螺母，以对转向杠杆进行牵引驱动，以从中部位置为混凝土层提供辅助支撑作用。
