Embodiment 1
[0046] Such as Figure 1 to Figure 7 The construction device of a steel-concrete composite beam prefabricated bridge deck shown includes: a lifting frame 1, a bridge deck 2, a pallet truck 3, and a track system 4;
[0047] Specific as figure 1 , 2 , 7, the track system 4 includes load-bearing rails 401, auxiliary auxiliary rails 402, first movable rails 403, and second movable rails 404. The load-bearing rails 401 and auxiliary auxiliary rails 402 are set up on the installed bridge deck of the bridge. The movable track 403 and the second movable track 404 are erected on the pier, and the heights of the load-bearing track 401, the auxiliary auxiliary rail 402, the first movable track 403, and the second movable track 404 are consistent. The first movable track 403 has the same structure as the second movable track 404, and the first movable track 403 and the second movable track 404 are all provided with an outer rail 411 and an inner rail 412 in parallel to form two tracks, ...
Embodiment 2
[0063] The difference between this embodiment and Embodiment 1 is that a rail hoisting mechanism 105 is also provided on the lifting frame 1, and the first movable rail 403 and the second movable rail 404 can move vertically and laterally along the bridge through the hoisting mechanism 105. move. The track hoisting mechanism 105 is used for the hoisting and moving forward of the two sections of movable rails. Only two sections of movable rails are needed to complete the laying of the entire bridge deck. The track occupies the defect of high cost; the lifting mechanism 101 is provided with a spreader 111, and the spreader 111 is collected and lowered by the lifting mechanism 101; the first movable track 403 and the second movable track 404 are provided with openings The slide rail 413 , the open slide rail 413 can be adapted to be slidably installed on the hanger 111 . Such as Figure 8 , 9 As shown, the hoisting mechanism 105 may include a horizontal hoisting assembly 115 a...
