A bridge erecting machine is a type of bridge construction machinery that places prefabricated girder beams onto prefabricated pile foundations; it falls under the category of cranes. However, it differs significantly from cranes in the general sense. Because its main function is to lift the girder beams, transport them to their designated positions, and then lower them, the requirements for its longitudinal movement on the erected girder beams are quite stringent.

[0017] Specifically, when lateral movement is required, the first hydraulic rod 4 is opened, and the extended end of the first hydraulic rod 4 drives the moving frame 5 to move. The moving frame 5 drives one end of the support beam 3 to move through the insertion slot 6, causing the support beam 3 to slide inside the sliding groove 2, thereby moving the moving frame 5 to the designated position. Then, the second hydraulic rod 8 is opened, and the extended end of the second hydraulic rod 8 drives the push seat 9 to move. The push seat 9 drives the support seat 10 to move downward, and the support seat 10 drives the telescopic frame 12 to move downward inside the telescopic groove opened in the support 11, thereby causing the bottom of the support seat 10 to be grounded on the pier. At the same time, the support seat 10 drives the limiting frame 13 to move downward.

[0018] Please refer to Figure 2 to Figure 4 The limiting frame 13 has a limiting hole 14 on one side, and a load-bearing seat 15 is fixedly installed on one side of the support 11. The load-bearing seat 15 has a lifting groove 16 inside, and the outer side of the limiting frame 13 is slidably connected to the inside of the lifting groove 16. A connecting seat 17 is fixedly installed on the top side of the load-bearing seat 15.

[0019] Specifically, the support base 10 will drive the limit frame 13 to move downward, so that the limit frame 13 moves downward inside the lifting groove 16.

[0020] Please refer to Figure 2 to Figure 4 A third hydraulic rod 18 is fixedly installed on the top of the connecting seat 17, and a pusher 19 is fixedly installed on the extended end of the third hydraulic rod 18.

[0021] Specifically, opening the third hydraulic rod 18 will cause the extended end of the third hydraulic rod 18 to move the pusher frame 19.

[0022] Please refer to Figure 2 to Figure 4 A sliding frame 20 is fixedly installed at the bottom of the pusher frame 19, and a limit post 21 is fixedly installed on one side of the sliding frame 20.

[0023] Specifically, one end of the pusher 19 will drive the sliding frame 20 to move, and the sliding frame 20 will drive the limiting post 21 to move.

[0024] Please refer to Figure 2 to Figure 4 A through hole 22 is provided on one side of the load-bearing base 15, and one end of the limiting post 21 is inserted into the inside of the limiting hole 14 through the through hole 22.

[0025] Specifically, one end of the limiting post 21 is inserted into the inside of the limiting hole 14 through the through hole 22, thereby limiting the limiting frame 13.

[0026] During use, when lateral movement is required, the first hydraulic rod 4 is opened. The extended end of the first hydraulic rod 4 drives the moving frame 5 to move. The moving frame 5 drives one end of the support beam 3 to move through the insertion slot 6, causing the support beam 3 to slide inside the sliding groove 2, thereby moving the moving frame 5 to the designated position. Then, the second hydraulic rod 8 is opened. The extended end of the second hydraulic rod 8 drives the push seat 9 to move. The push seat 9 drives the support seat 10 to move downward. The support seat 10 drives the telescopic frame 12 to move, causing the telescopic frame 12 to move in the telescopic groove opened in the support 11. The internal movement of the support seat 10 downwards causes the bottom of the support seat 10 to be grounded on the pier. At the same time, the support seat 10 drives the limiting frame 13 to move downwards, causing the limiting frame 13 to move downwards inside the lifting groove 16. When limiting is required, the third hydraulic rod 18 is opened. The extended end of the third hydraulic rod 18 drives the pusher 19 to move. One end of the pusher 19 drives the sliding frame 20 to move. The sliding frame 20 drives the limiting post 21 to move. One end of the limiting post 21 is inserted into the limiting hole 14 through the through hole 22, thereby limiting the limiting frame 13.
