[0023] See also Figure 1-4 A lifting structure for bridge construction includes a car body 1, a control room 2 is fixedly installed on the upper surface of the car body 1, a side plate 3 is fixedly installed on the right surface of the control room 2, a fixed mounting frame 4 is arranged on the rear side of the car body 1, a slide plate 5 is fixedly installed on the left surface of the fixed mounting frame 4, a limiting groove 6 is arranged on the upper surface of the slide plate 5, a movable mounting frame 7 is movably installed on the outer surface of the slide plate 5, an outer frame 8 is fixedly installed on the upper surface of the movable mounting frame 7, a telescopic rod 9 is fixedly installed on the lower surface of the outer frame 8, a limiting block 10 is fixedly installed on the lower end of the telescopic rod 9, hook plates 11 are fixedly installed on the upper surfaces of the fixed mounting frame 4 and the movable mounting frame 7, a limiting hole is arranged on the upper surface of the movable mounting frame 7, a slide groove is arranged on the right surface of the movable mounting frame 7, and the outer surface of the slide plate 5 is movably connected with the inner wall of the slide groove.
[0024] Working principle: When lifting the bridge, first measure the length of the bridge, then place one end of the bridge completely inside the fixed mounting frame 4, then start the telescopic rod 9, and drive the limit block 10 fixedly connected to its lower end to move, until the limit block 10 is completely moved out of the limit groove 6 on the upper surface of the slide plate 5, move the movable mounting frame 7 until the required length is reached, and then adjust the length again. When the other end of the bridge is placed inside the movable mounting frame 7, adjust the length back to the required length. After completion, start the telescopic rod 9 again to drive the limit block 10 to enter the limit groove 6 again, thereby fixing the slide plate 5, and then connect the hanging rope to the outside, one end of which is connected to the hook plate 11, and the other end is connected to the hook 16 for lifting. This design can stably lift bridges of different lengths to avoid the phenomenon of bridges falling during the lifting process.
[0025] Embodiment 2:
[0026] See also Figure 1-4 Based on the first embodiment, the present invention provides a technical solution:
[0027] In this embodiment: a winding structure 12 is provided on the upper surface of the side plate 3, a rotating structure 13 is provided on the upper surface of the side plate 3, a nylon rope 14 is connected to the outer surface of the winding structure 12, a counterweight block 15 is fixedly installed on the top of the nylon rope 14, a hook 16 is fixedly installed on the lower surface of the counterweight block 15, baffles 17 are fixedly installed on both side surfaces of the counterweight block 15, movable plates 18 are fixedly installed on both sides of the counterweight block 15, a fixed plate 19 is fixedly installed on the lower surface of the counterweight block 15, a spring 20 is fixedly installed on the lower surface of the movable plate 18, the lower end of the spring 20 is fixedly connected to the right surface of the fixed plate 19, the lower surface of the baffle 17 is not connected to the upper surface of the movable plate 18, a roller is fixedly installed on the top of the rotating structure 13, and the outer surface of the roller is movably connected to the outer surface of the nylon rope 14.
[0028] Working principle: when the hook 16 rope is hung on the hook 16, the movable plate 18 is manually pressed down, and the movable plate 18 rotates downward to squeeze the spring 20, thereby giving the spring 20 a force. After that, the hook 16 rope is put in, and the force squeezing the movable plate 18 is released. The spring 20 pushes the movable plate 18 to reset due to its own resilience. After touching the baffle 17, the baffle 17 blocks the movable plate 18, thereby limiting the movable plate 18. This design can achieve the effect of limiting and fixing the hook 16, and avoid the situation where the hook 16 falls off and causes the bridge to fall when it is lifted.
