Technical Field

[0001] The utility model relates to the field of steel strip transportation equipment, and particularly relates to a small crane for loading and unloading steel strips. Background Art

[0002] A steel strip, also known as a strip steel, has a width within 1300 mm, and its length varies slightly according to the size of each roll. The steel strip has the advantages of high dimensional accuracy, good surface quality, easy processing, and material saving. During the production and transportation process, the steel strip is in a coiled state. When transporting such a steel strip, due to its heavy weight, it is difficult to operate manually. Therefore, a large bridge crane is generally required for transportation. However, using a large crane occupies a large space and has a high input cost. Content of the Utility Model

[0036] The following refers to Figures 1 - 3 A small hoist for steel belt loading and unloading is described in detail with a specific embodiment. It should be understood that the following description is only an exemplary illustration and not a specific limitation of the utility model.

[0037] As Figures 1 - 3 shown, a small hoist for steel belt loading and unloading includes an arc-shaped guide rail 100, a fixing mechanism and a moving mechanism.

[0038] Among them, one end of the arc-shaped guide rail 100 is located above the steel belt production equipment 110, and the other end is located above the loading and unloading area; the fixing mechanism includes support columns 120 arranged at both ends of the arc-shaped guide rail 100 and a gantry 130 for fixing the top of the arc-shaped guide rail 100; the moving mechanism includes a trolley moving along the arc-shaped guide rail 100 and a winch 140 for pulling the steel belt. By adopting a single arc-shaped guide rail 100, it can directly connect above the steel belt production equipment 110 and above the loading and unloading area; the fixing mechanism is supported by the support columns 120 on both sides of the arc-shaped guide rail 100, and at the same time is strengthened by setting a gantry 130 on the top of the arc-shaped guide rail 100 to ensure the structural stability; the moving mechanism moves the trolley along the arc-shaped guide rail 100 and pulls the steel belt through the winch 140 to drive the steel belt to move along the arc-shaped guide rail 100. Therefore, there is no need to use a large bridge crane for transportation, which can save space and has a low input cost.

[0039] As Figure 2 and Figure 3 shown, guide grooves 150 are provided on both sides of the arc-shaped guide rail 100, and the trolley is provided with guide wheels 160 that cooperate with the guide grooves 150. Such a setting is beneficial for the trolley to be closely matched with the arc-shaped guide rail 100 through the guide wheels 160 to prevent the trolley from detaching from the arc-shaped guide rail 100. Specifically, two guide wheels 160 are provided on one side of the trolley. Having two guide wheels 160 on one side is beneficial for the trolley to be closely matched with the arc-shaped guide rail 100. Moreover, a driving motor 170 is also provided on the trolley to drive the guide wheels 160 to move. Setting the driving motor 170 can control the movement of the trolley on the arc-shaped guide rail 100. Further, the driving motor 170 drives the guide wheels 160 to move through a belt drive. Through the belt drive, the driving motor 170 can stably drive the guide wheels 160 to move.

[0040] AsFigure 2 As shown, the support column 120 at one end of the steel strip production equipment 110 where the arc-shaped guide rail 100 is located is provided on the steel strip production equipment 110. Setting the support column 120 on the steel strip production equipment 110 can reduce the length of the support column 120, save materials, and does not affect the loading and unloading of the trolley on the steel strip production equipment 110.

[0041] It should be noted that the gantry 130 includes a cross beam 180 connected to the top of the arc-shaped guide rail 100 and columns 190 for fixing both ends of the cross beam 180. The gantry 130 is set in this way with a stable structure and can effectively reinforce the arc-shaped guide rail 100.

[0042] It can be understood that, as Figure 3 shown, a hook 200 is connected to the lower end of the winch 140 through a steel rope. By setting the hook 200, the steel strip can be conveniently lifted.

[0043] It is worth mentioning that there are two small cranes for loading and unloading the steel strip, one is located between the steel strip loading area and the steel strip production equipment 110, and the other is located between the steel strip unloading area and the steel strip production equipment 110. Setting two small cranes for loading and unloading the steel strip can load the steel strip production equipment 110 while unloading it, with high production efficiency.

[0044] In the description of this specification, the description with reference to terms such as "one embodiment, some embodiments, illustrative embodiments, examples, specific examples or some examples" means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present utility model. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0045] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the purpose of the present utility model within the scope of knowledge possessed by those of ordinary skill in the art.
