[0025] like Figures 1 to 6 As shown, embodiment 1: a prefabricated box beam winter insulation mechanism, comprising a group of adjustment slots 4, one end of each of the adjustment slots 4 is respectively connected to a fixed shaft 7, each of the adjustment slots 4 is respectively connected to a T shaft 16, and each of the adjustment slots 4 is respectively connected to a guide round rod 11; a group of symmetrical adjustment blocks 13, each of the adjustment blocks 13 is respectively arranged in the corresponding adjustment slots 4, each of the guide round rods 11 passes through the corresponding adjustment blocks 13, and each of the adjustment blocks 13 is respectively connected to a movable shaft 8; a group of staggered air pipes 5, each of the air pipes 5 is respectively fixedly connected to a group of nozzles 6, each of the air pipes 5 is respectively connected to a mounting block 9, and each of the mounting blocks 9 is respectively connected to a corresponding adjustment block 13. The spacing of the adjustment slots 4 is adjustable, and the air pipes 5 are adjustable along the length direction of the adjustment slots 4, so as to achieve adjustment according to the size of the prefabricated box beam and achieve insulation of the prefabricated box beam.

[0026] Each of the fixed shafts 7 is respectively rotatably connected to one end of the deployment rod 1, and the other end of each of the deployment rods 1 is respectively rotatably connected to the corresponding movable shaft 8, and each of the movable shafts 8 is respectively rotatably connected to one end of the side rod 2, and each of the T shafts 16 is respectively rotatably connected to the center of the middle connecting rod 3, and the other end of each of the side rods 2 is respectively rotatably connected to one end of the corresponding middle connecting rod 3.

When the cylinder 18 is placed on the top surface of the prefabricated box beam, the cylinder 18 is used to achieve contact with the arc of the prefabricated box beam, thereby avoiding damage to the prefabricated box beam.
