[0028] The precast slab erection device disclosed in this utility model is mainly used in the scenario of precast slab erection for highway traffic bridge construction.

[0029] Reference Figure 1 - Figure 5 A precast slab erection device for highway traffic bridge construction includes a base 1, a lifting plate 2 on the top of the base 1, a motor 3 fixedly connected to the bottom of the inner wall of the base 1, and a lifting mechanism on the top of the base 1. The lifting mechanism includes a lifting component and a positioning component, which cooperate with each other. The lifting component includes a top plate 41, which is fixedly connected to the bottom of the lifting plate 2. A bottom plate 48 is fixedly connected to the bottom of the inner wall of the base 1, and fixing blocks 42 are symmetrically fixedly connected to the top of the bottom plate 48. Rotary connecting rods are rotatably connected to the outer sides of both fixing blocks 42. The top of the moving plate 43 and the base plate 48 are symmetrically fixedly connected to fixed seats 44. Threaded columns 411 are rotatably connected inside the two fixed seats 44. Moving blocks 46 are threadedly connected to the outer side of the threaded columns 411. Connecting rods 47 are symmetrically fixedly connected to the outer side of the moving blocks 46. Adjusting rods 45 are rotatably connected to the outer side of each of the two connecting rods 47. The bottom of the top plate 41 is symmetrically provided with sliding grooves 49. Translation columns 410 are slidably connected inside the sliding grooves 49. Translation columns 410 and the rotating plate 43 are rotatably connected. The output end of the motor 3 is fixedly connected to the threaded columns 411.

The outer side of the base 1 is fixedly connected with a fixing frame 9, and the outer side of the fixing frame 9 is fixedly connected with a controller 10.
