[0002] Steel structures are widely used and come in many varieties. According to the different cross-sectional shapes, steel structures are generally divided into four categories: profiles, plates, pipes and metal products. Steel is a material of a certain shape, size and performance made by ingots, billets or steel through pressure processing. Most steel structure processing is done through pressure processing, which causes plastic deformation of the processed steel (billets, ingots, etc.). According to the different processing temperatures of steel, it can be divided into cold processing and hot processing.
[0003] After production, existing steel structures are usually difficult to move due to their own weight, and a crane is needed to lift and move them. However, it is not convenient to use a crane to move smaller steel structures or in a small space. If they are moved manually, there is a risk of injuring workers due to the heavy steel structure. At the same time, manual transportation is inconvenient. The existing transport trolley has a weak structure, and when transporting heavier steel structures, the transport trolley may be deformed or damaged, and the service life of the transport trolley is short. Utility Model Content
[0004] The purpose of the utility model is to provide a special steel structure trolley in view of the shortcomings of the prior art, so as to solve the problem that the existing transport trolley has a weak structure and may be deformed or damaged when transporting the steel structure, thereby shortening the service life of the transport trolley.

[0029] The following is combined with Figure 1-2 The utility model is further described in detail, but it is not intended to limit the utility model.
[0030] The utility model provides a special steel structure trolley, comprising a carrier plate 1 and a rolling component 2 arranged at the lower side of the carrier plate 1, a reinforcing structure 3 is arranged between the carrier plate 1 and the rolling component 2, one end of the reinforcing structure 3 is connected to the rolling component 2, and the other end of the reinforcing structure 3 is connected to the carrier plate 1, and the upper surface of the carrier plate 1 is a flat plane.
[0031] Specifically, the carrier plate 1 in the present invention is used to carry steel structures. The carrier plate 1 is a whole solid structure, so the carrier plate 1 can carry heavy steel structures without deformation. At the same time, a rolling component 2 is arranged on the lower side of the carrier plate 1 to facilitate the movement of the carrier plate 1 and the steel structures on the carrier plate 1. The steel structures can be moved to any flat ground through the rolling component 2. At the same time, a reinforcing structure 3 is arranged between the rolling component 2 and the carrier plate 1 to improve the load-bearing capacity of the entire transportation device. When transporting heavy steel structures, the carrier plate 1 directly bears the weight of the steel structures, and the rolling component 2 needs to bear the weight of the carrier plate 1 and the steel structures. The setting of the reinforcing structure 3 can help the rolling component 2 bear part of the weight during transportation, thereby improving the load-bearing capacity of the rolling component 2. At the same time, the reinforcing structure 3 can also improve the structural strength of the rolling component 2 to prevent it from deformation.
[0032] In some embodiments, two rolling components 2 are provided, each rolling component 2 includes two rollers and a roller shaft, the two rollers are symmetrically arranged at both ends of the roller shaft, and the roller shaft is passed through the two rollers. The balance of the roller shaft is maintained by the rollers, so that the rolling component 2 moves more smoothly. At the same time, the two rollers enable the rolling component 2 to stand independently, and no additional supporting structure is required to support the rolling component 2.
[0033] In some embodiments, the roller shaft and the carrier plate 1 are connected via a connecting block 4 , a bearing is disposed on the connecting block 4 , and the roller shaft passes through the bearing.
[0034] Specifically, the carrier plate 1 is connected to the roller shaft through the connecting block 4. The connecting block 4 has a plane, which is fixedly connected to the carrier plate 1. The connecting block 4 also has a through groove, in which a bearing is arranged. The roller shaft passes through the bearing. When the roller shaft rotates, the carrier plate 1 will not be affected due to the action of the bearing, and the carrier plate 1 will only be driven to move.
[0035] In some embodiments, two rolling components 2 are arranged parallely and symmetrically on the lower side of the carrier plate 1 .
[0036] Specifically, the two rolling components 2 are arranged in parallel and symmetrically to ensure the consistency of movement of the carrier 1 during movement. At the same time, the carrier 1 is supported by the two rolling components 2, so that the carrier 1 does not need to be supported by other supporting components.
[0037] The two rolling components 2 are arranged at the two ends farthest from the lower side of the carrier 1. The above arrangement can ensure that the center of the object on the carrier 1 is always located at the center of gravity of the carrier 1, preventing the carrier 1 from tilting forward due to the center of gravity being too forward, or the carrier 1 from tipping over due to the center of gravity being too backward when the carrier 1 is moving the load, thereby greatly improving the transportation safety of the transportation device.
[0038] In some embodiments, a plurality of reinforcing structures 3 are provided, and the plurality of reinforcing structures 3 are respectively provided on both sides of the rolling component 2 .
[0039] Specifically, when the transport device in the utility model transports some heavier steel structures, the weight of the steel structure directly acts on the carrier plate 1, and the carrier plate 1 transfers the weight to the rolling component 2. Therefore, the rolling component 2 needs to bear the weight of the carrier plate 1 and the steel structure itself. The heavier weight will cause the roller to bend and deform. In this embodiment, a reinforcing structure 3 is provided to increase the load-bearing capacity of the roller, prevent the roller from bending, and at the same time increase the service life of the entire transport device.
[0040] In some embodiments, a hook 11 is disposed on the carrier 1 , and the hook 11 is fixedly disposed on a side of the carrier 1 .
[0041] Specifically, a hook 11 is provided on one side of the carrier plate 1, and the hook 11 can cooperate with other structures to perform operations, such as dragging heavy objects.
[0042] In some embodiments, a towing hook 12 is further disposed on the carrier plate 1 , and the towing hook 12 is disposed opposite to the hook 11 , and the setting direction of the hook 11 and the towing hook 12 is perpendicular to the setting direction of the roller shaft.
[0043] Specifically, the towing hook 12 and the hook 11 can be used in conjunction with each other. When some longer steel structures need to be transported, several transport devices can be connected in series through the hook 11 and the towing hook 12 to increase the load length of the transport device. During the specific connection, the hook 11 is connected to the towing hook 12.
[0044] Furthermore, other driving mechanisms may be connected to the towing hook 12 to tow the transport device.
[0045] In some embodiments, a limiting member 13 is detachably provided on the carrier plate 1 , and at least four limiting members 13 are provided, and the four limiting members 13 are arranged in a surrounding shape.
[0046] Specifically, when the transport device carries the steel structure for transportation, the steel structure may be displaced or even fall out of the transport device when passing through uphill, downhill or bumpy sections, which will pose a safety hazard to the life safety of the workers. At the same time, since the steel structure is heavy, after falling out of the transport device, it needs to be re-placed by a lifting device, which is extremely inconvenient. Therefore, a limit member 13 is provided on the carrier plate 1, and the steel structure is limited by the limit member 13 to prevent the steel structure from being displaced.
[0047] In some embodiments, the roller is a hollow rubber wheel.
[0048] Specifically, since the steel structure is heavy, if a solid wheel is used as the roller, the buffering effect of the solid wheel is not ideal. When passing through a bumpy road section, the steel structure will be caused to bump up and down, resulting in the risk of the steel structure being out of the limit of the limit member 13. The hollow rubber wheel has an ideal buffering effect, which can prevent the steel structure from jumping out of the limit of the limit member 13, greatly increasing safety.
[0049] In some embodiments, a driving mechanism is further disposed on the lower side of the carrier plate 1 , the output end of the driving mechanism is connected to the roller shaft, and the driving mechanism drives the rotating shaft to rotate.
[0050] Specifically, the driving mechanism is connected to the roller shaft, and the driving structure drives the rotating shaft to rotate, so that the transport device moves, which has a high degree of automation, saves labor, and no longer requires manual pushing.
[0051] The transport device in the utility model can also work together with an external drive device, which can effectively reduce the load of the drive structure and increase the service life of the drive structure.
[0052] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
[0053] According to the disclosure and teaching of the above description, the technicians in the field of the utility model can also change and modify the above implementation. Therefore, the utility model is not limited to the above specific implementation, and any obvious improvement, replacement or modification made by the technicians in this field on the basis of the utility model belongs to the protection scope of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of explanation and do not constitute any limitation to the utility model.
