External pushing device for rigid frame bridge body
The invention relates to the technical field of bridge engineering, and particularly discloses a rigid frame bridge external pushing device which comprises a double-I-shaped steel rail, the double-I-shaped steel rail is connected with a machine body in a sliding mode, extension rods are fixedly installed at the four corners of the machine body, the extension rods are fixedly connected with fixing shafts, and the fixing shafts are fixedly connected with the double-I-shaped steel rail. The fixing shaft is rotationally connected with a first rotating arm rod, one end of the first rotating arm rod is rotationally connected with an abutting block, a brake pad is arranged at one end of the abutting block, lifting pressing rods are slidably connected to the four corners of the machine body correspondingly, and first connecting arm rods are rotationally connected to the two sides of one end of each lifting pressing rod correspondingly. When the device is used for pushing and supporting a bridge, a machine body can be effectively limited and fixed to a track, so that the machine body is prevented from position deviation due to the influence of external force, and the service life of the machine body is prolonged. And the precision of follow-up bridge butt joint is further influenced.
本发明涉及桥梁工程技术领域，具体公开了一种刚构桥体外顶推装置，该刚构桥体外顶推装置，包括有双工字钢轨，所述双工字钢轨滑动连接有机体，所述机体的四角处均固定安装有延伸杆，所述延伸杆固定连接有固定轴，所述固定轴转动连接有转动臂杆一，所述转动臂杆一的一端转动连接有抵接块，所述抵接块的一端设置有刹片，所述机体的四角处均滑动连接有升降压杆，所述升降压杆一端的两侧均转动连接有连接臂杆一，一个所述连接臂杆一与转动臂杆一转动连接，另一个所述连接臂杆一与抵接块的另一端转动连接，装置在对桥梁进行顶推支撑时，能有效的将机体限位固定在轨道上，从而防止机体受到外力影响而出现位置偏移，进而影响到后续桥梁对接时的精度。
