[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0020] refer to Figures 1-4The lifting control device of a bridge crane shown includes columns 1 and track beams 3. There are at least three sets of columns 1 connected in the same row via track beams 3. The track beams 3 are connected to the columns 1 via fixed supports 2. There are two sets of track beams 3 arranged parallel to each other, connected by a movable crossbeam 4. The movable crossbeam 4 is equipped with a moving mechanism 5 for adjusting hooks 7. To prevent hooks 7 from swinging during crane movement, causing interference or collisions with other objects and resulting in unnecessary damage, the moving mechanism 5 also includes a mounting plate 55 and a connecting block 53. The mounting plate 55 is connected to the connecting block 53 via electric telescopic rods 54. Multiple sets of electric telescopic rods 54 are connected by a support mechanism 8. The mounting plate 55 has traveling wheels 56 on both sides, each driven by a moving motor. The moving mechanism 5 and the lifting control device... The control mechanisms 6 are also connected by steel cables 51 to prevent the hook 7 from swinging when the bridge crane moves the hook 7. In order to make the lifting and lowering of the hook 7 easier to control, the moving mechanism 5 also includes a movable pulley housing 52. The movable pulley housing 52 is mounted on the connecting block 53. A movable pulley is rotatably connected inside the movable pulley housing 52. The movable pulley makes the service life of the steel cable 51 longer. The movable pulley housing 52 is also connected to the lifting control mechanism 6 through the steel cable 51. A groove that matches the steel cable 51 is formed between the movable pulley housing 52 and the movable pulley. One end of the steel cable 51 is first connected to one of the rotating blocks on the rotating shaft 61. Then the steel cable 51 passes through the groove formed between the movable pulley housing 52 and the movable pulley, so that the other end is connected to the limiting block 62. There are two sets of limiting blocks 62 and rotating blocks. The rotating shaft 61 is driven by the drive motor 63. The limiting block 62, the rotating shaft 61 and the drive motor 63 are all set on the mounting plate 55.

[0021] As one implementation method in this embodiment, to avoid the problem of reduced lifespan of the steel cable 51 due to prolonged friction between the steel cable 51 and the mounting plate 55 of the moving mechanism 5, and to increase the load-bearing strength of the moving mechanism 5 and improve the limiting effect of the moving mechanism 5 on the hook 7, the support mechanism 8 also includes a connecting rod 81 and a support pulley 83. The two ends of the connecting rod 81 connect adjacent electric telescopic rods 54, and the connecting rod 81 is connected to the mounting plate 55 through a connecting column 84. The connecting rod 81 and the support pulley 83 are connected through a support rod 82, so that the moving mechanism... The connection between the electric telescopic rods 54 in section 5 is more stable, further avoiding the problem of hook 7 swinging when the bridge crane moves. Multiple sets of support pulleys 83 are provided, and the support pulleys 83 are symmetrically arranged on both sides of the connecting rod 81. Support mechanisms 8 are provided between adjacent electric telescopic rods 54. At the same time, the position of the support pulleys 83 corresponds to the position of the limit block 62, so that the steel cable 51 will come into contact with the support pulleys 83. The support pulleys 83 spread the steel cable 51 to both sides, avoiding direct friction between the steel cable 51 and the mounting plate 55, thus extending the service life of the steel cable 51.

[0022] The working principle of this practical application is as follows: First, connect the column 1 and the track beam 3 via the fixed support 2. Then, connect the moving mechanism 5 to the track beam 3 via the moving crossbeam 4, allowing the moving crossbeam 4 to slide on the track beam 3. The moving mechanism 5 can also slide on the moving crossbeam 4. Next, connect one end of the steel cable 51 to the rotating block of the rotating shaft 61, and the other end passes through the movable pulley housing 52 and is then connected to the limiting block 62. Simultaneously, make the steel cable 51 contact the supporting pulley 83, thus completing the assembly of the bridge crane. Then, start the moving motor. By controlling the moving motor that drives the moving crossbeam 4, adjust the position of the moving crossbeam 4 on the track beam 3. By controlling the moving motor that drives the moving mechanism 5, adjust the position of the moving mechanism 5 on the moving crossbeam 4. The movement is simultaneous... When the hook 7 is connected to the electric telescopic rod 54 via the connecting block 53, the hook 7 will not swing during movement due to the limiting effect of the electric telescopic rod 54. When the hook 7 moves to the working position, the drive motor 63 is controlled to drive the rotating shaft 61 to rotate synchronously. The rotating block on the rotating shaft 61 winds the steel cable 51, which drives the pulley housing 52 to move upward through the steel cable 51. At the same time, the electric telescopic rod 54 moves upward synchronously, driving the connecting block 53 to move upward, so that the hook 7 connected to the bottom of the connecting block 53 lifts the item upward. Then, by operating the moving motor of the moving mechanism 5 and the moving motor of the moving beam 4 respectively, the item can be moved to the required position, thus completing the handling of the item. At the same time, the problem of the hook 7 causing the item on the hook 7 to swing during the handling process is avoided.
