Mid-span damping type stepless self-locking pushing device for flat-turning opening bridge
The invention discloses a mid-span damping type stepless self-locking pushing device of a flat-turning opening bridge. The mid-span damping type stepless self-locking pushing device is composed of a bridge pushing structure, a stepless self-locking structure, a bridge damping device, a stepping motor servo system and a box body; the bridge damping structure is located on the left side of a bridge;the stepless self-locking structure is located on the right side of the bridge; the bridge pushing structure is located between the bridge damping structure and the stepless self-locking structure; and the stepping motor servo system is located on one side of the stepless self-locking structure of the bridge. The bridge pushing structure comprises a floating block and a pushing rod; the floatingblock contacts with a left box body to achieve horizontal force transmission; the pushing rod is connected with the floating block to transmit horizontal force to a right wedge block; and therefore, self-locking is achieved through the friction pair of the wedge block and the box body. The bridge damping structure comprises a spring baffle, a high-strength spring and a viscous damper. The balancedamping of the bridge is achieved through the high-strength spring and the viscous damper, and the pushing structure can work stably and effectively. The stepless self-locking structure comprises a wedge block, an ejector rod and a box body; and a stepless self-locking function is achieved through a special treatment friction pair. The lead screw of the stepping motor servo system is connected with a sliding box body, so that the sliding function of the pushing rod and the unlocking function of the self-locking structure are achieved; the box body is effectively connected with the bridge floorthrough high-strength friction type bolts. According to the device, a left bridge and a right bridge can be connected through the damping type stepless self-locking pushing device, and loads are stably and effectively transmitted. The device is simple in structure, excellent in bearing performance, high in safety coefficient and low in cost.
