[0002] Double-girder bridge crane is a kind of heavy lifting equipment widely used in industry and construction, mainly used for material handling, loading, unloading and stacking.
[0003] According to observations based on the prior art, a hook is required to retrieve goods during use. The goods are heavy, and the weight will act on the rollers and the rotating rod during the transportation process. The rotating rod will bend under the action of gravity, and the bending will squeeze the rollers, causing the rollers to shift. After the rollers shift, they will be misaligned with the track, causing the rollers to move unsmoothly and causing serious wear of the roller molds. If the rollers are severely worn, they may fall off the track during subsequent use, causing the crane to drop materials. Utility Model Content

[0012] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:
[0013] 1. A stabilizing ring is provided in the utility model, and pressure is applied to the slider when the rotating rod is bent. When the slider moves, it pushes the first airbag on the push plate. The first airbag generates gas during the extrusion process to inflate the second airbags at both ends, which can form a thrust on the rotating rod, thereby preventing the degree of rotational deformation, thereby reducing the extrusion of the roller, allowing the roller to roll smoothly on the track, reducing friction, and extending the service life. The airbag is adopted because the airbag has high toughness and good durability and can be used for a long time.
[0014] 2. A buffer block is provided in the utility model. When the roller is subjected to the pressure brought by the rotating rod, the roller tilts and the force acts on the buffer block. The buffer block transfers the force to the sliding rod. The sliding rod engages with the damping block to reduce the impact force, thereby avoiding the situation where the roller is deformed due to excessive impact force, reducing rigid impact and ensuring the service life of the roller.

[0022] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.
[0023] A double-beam bridge crane provided by some embodiments of the utility model will be described below in conjunction with the accompanying drawings.
[0024] Combination Figure 1-5 As shown, a double-beam bridge crane provided by the utility model comprises a bridge frame 1, two ends of the bridge frame 1 are fixedly connected with a moving box 2, one side of the moving box 2 is rotatably connected with a rotating rod 3 in a through-shaped manner, one end of the rotating rod 3 is fixedly connected with a roller 4, one end of the rotating rod 3 is rotatably connected with a stabilizing ring 5 in a through-shaped manner, one side of the stabilizing ring 5 is slidably connected with a slider 6 in a through-shaped manner, one end of the slider 6 is fixedly connected with a push plate 7, one end of the push plate 7 is fixedly connected with a first air bag 8, two ends of the first air bag 8 are fixedly connected with a connecting hose 9 in a connected manner, two ends of the connecting hose 9 are fixedly connected with a second air bag 10 in a connected manner, and one end of the second air bag 10 is slidably connected with a push block 11 in a through-shaped manner;
[0025] The outer wall of the stabilizing ring 5 is symmetrically fixedly connected to a first spring 12, one end of the first spring 12 is fixedly connected to a lubrication box 13, one side of the lubrication box 13 is fixedly connected to the inner wall of the moving box 2, there are two bridge frames 1, a connecting plate 20 is fixedly connected between the bridge frames 1, the top of the connecting plate 20 is fixedly connected to a power box 21, a hook 23 is provided at the bottom of the power box 21, and the side wall of the bridge frame 1 is fixedly connected to a control room 22.
[0026] In the first embodiment, when the rotating rod 3 is deformed, the pressure is transmitted to the stabilizing ring 5. The slider 6 in the stabilizing ring 5 will move after receiving the pressure. When moving, the pressure can be applied to the first airbag 8 through the push plate 7. The first airbag 8 is squeezed and the internal gas can be transported to the second airbag 10 at both ends of the connecting hose 9, so that the push block 11 in the second airbag 10 is pushed out to support the rotating rod 3. This can reduce the deformation of the rotating rod 3 and also has the ability of self-calibration, thereby reducing the deformation of the roller 4, ensuring that the roller 4 can slide in accordance with the track normally, reducing the friction of the roller 4, ensuring the normal movement of the equipment and the service life of the equipment.
[0027] The side of the roller 4 is slidably connected with a buffer mechanism, which includes a ball 19, one side of the ball 19 is slidably connected with a support block 18 in a through-shaped manner, one side of the support block 18 is fixedly connected with a buffer block 14, one side of the buffer block 14 is slidably connected with a sliding rod 15 in a through-shaped manner, and both sides of the sliding rod 15 are slidably connected with damping blocks 16. There are two damping blocks 16, one side of which is fixedly connected to the inner wall of the buffer block 1414, one end of the sliding rod 15 is fixedly connected to a second spring 17, and one end of the second spring 17 is fixedly connected to the inner wall of the buffer block 14.
[0028] In the second embodiment, when the roller 4 is subjected to pressure, the pressure will be transferred to the buffer block 14. When the buffer block 14 moves, it will drive the internal damping block 16 and the sliding rod 15 to perform sliding damping, thereby reducing the stroke of the buffer block and then offsetting the pressure. After offsetting, the offset angle of the roller 4 can be slowed down, thereby ensuring that the roller 4 can rotate normally.
[0029] The working principle and use process of the utility model are as follows: when the rotating rod 3 is deformed to form an extrusion pressure on the sliding block 6 in the stabilizing ring 5, the pressure will drive the push plate 7 to move to squeeze the first airbag 8, and the first airbag 8 will transport the gas to the second airbag 10 through the connecting hose 9. The gas in the second airbag 10 can push the push block 11 out to squeeze the rotating rod 3. At the same time, the force of the rotating rod 3 when deformed acts on the roller 4 to deflect the roller 4, and the roller 4 will exert force on the buffer block 14. Subsequently, the movement of the buffer block 14 will drive the damping block 16 and the sliding rod 15 to perform friction deceleration, thereby reducing the force when the roller 4 is offset, and avoiding excessive rigid impact to damage the roller 4 again.
[0030] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
