The invention relates to the technical field of boarding bridge chain breakage detection, and discloses a chain breakage detection and emergency braking device for boarding bridge. The device comprises an arc-shaped block and a sleeve, two reset springs are fixedly connected to the interior of the sleeve, and ejector rods are fixedly connected to the sides, opposite to each other, of the two resetsprings. The opposite sides of the two ejector rods are rotationally connected with ejector wheels correspondingly, the left sides of the two ejector rods are rotationally connected with pull rods correspondingly, a movable wheel is rotationally connected into the arc-shaped block, the right side of the movable wheel is rotationally connected with a gear, and the front face of the gear is rotationally connected with a rotating rod. A brake button and a sliding rod are fixedly connected to the lower portion of the right side of the arc-shaped block, and the sliding rod is sleeved with a sliding block. The top wheel moves away from the reset spring under the action of the reset spring, then the pull rod, the gear and the rotating rod are matched to drive the arc-shaped face on the left sideof the sliding block to extrude the brake button, and then the emergency brake device rapidly brakes the driving chain wheel.

    本发明涉及登机桥断链检测技术领域,且公开了一种登机桥用断链检测并紧急制动装置,包括弧形块和套筒,所述套筒的内部固定连接有两个复位弹簧,两个所述复位弹簧相背的一侧均固定连接有顶杆,两个所述顶杆相背的一侧均转动连接有顶轮,两个所述顶杆的左侧均转动连接有拉杆,所述弧形块的内部转动连接有活动轮,所述活动轮的右侧转动连接有齿轮,所述齿轮的正面转动连接有转动杆,所述弧形块右侧的下方固定连接有制动按钮和滑杆,所述滑杆的外部套接有滑块。通过顶轮在复位弹簧的作用下向远离复位弹簧的方向移动,然后通过拉杆、齿轮和转动杆配合带动滑块左侧的弧形面挤压制动按钮,进而使紧急制动装置快速对主动链轮进行制动。
