DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0026] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0027] The terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise stated, the meaning of "plurality" is two or more.

[0028] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be directly connected, or indirectly connected through an intermediate medium, and may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0029] Embodiment 1

[0030] From the above Figures 1-4 It can be seen that the large gantry type lifting and transporting device designed in this embodiment, the present utility model includes a fixed support frame 1, a transmission system 2, support pulleys (support sprockets) 3, lateral guiding brackets 4, a counterweight guiding bracket 5, a counterweight 6, guiding wheels 7, end guiding brackets 8, a lifting frame 9, a driving roller assembly 10, and a slab 11.

[0031] The fixed support frame 1 is used as the support component of the structure and is welded by section steel.

[0032] The transmission system 2 is installed on the top of the fixed support frame 1 and mainly includes a reduction motor, a coupling, a brake, a driving pulley (driving sprocket), and a steel wire rope (chain). One end of the steel wire rope (chain) is connected to the lifting frame 9, and the other end is connected to the counterweight 6. The brake is used to control the start and stop of the motor on the one hand and can ensure the limit position accuracy of the lifting frame 9 on the other hand.

[0033] The supporting pulley (supporting sprocket) 3 serves as an auxiliary adjustment mechanism, which can not only control the wrap angle of the wire rope (chain) and the driving pulley (driving sprocket) in the drive system, but also adjust the connection position of the counterweight 6.

[0034] The counterweight 6 mainly functions to save energy. The weight selection of the counterweight 6 mainly depends on the lifting weight at the lifting frame 9 and the maximum slab weight. According to the calculation principle of the elevator counterweight, usually, the total weight of the lifting frame 9 and the driving roller assembly 10 and half of the maximum slab weight are taken as the total weight of the counterweight.

[0035] The counterweight guiding bracket 5 is used to restrict the position of the counterweight 6 to ensure that the counterweight 6 does not swing during the lifting process. The guiding wheels 7 are respectively installed on the side and end of the lifting frame 9 and are used for position limiting during the lifting process.

[0036] The lateral guiding bracket 4 and the end guiding bracket 8 are respectively installed at the side and end face positions of the lifting frame 9 and serve as the slideways of the guiding wheels 7. Acting together with the guiding wheels 7, they restrict the position of the lifting frame 9. A number of driving roller assemblies 10 are installed on the lifting frame 9. At the high position, the slab 11 is received through the driving rollers; after descending to the low position, the slab 11 is transported away through the driving rollers, and finally the lifting and transportation goal of the slab 11 is achieved.

[0037] Compared with the previous lifting roller table, the lifting and transportation device shown in the present utility model has larger size specifications, heavier transportation weight, and higher lifting distance. The structure of the present utility model is simple and practical, convenient for maintenance, energy-saving and reliable, with perfect functions. Considering the overall situation of structural optimization and cost control, it has strong market competitiveness.

[0038] The above has described the present utility model in detail with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art, various changes can be made without departing from the purpose of the present utility model. Many other changes and modifications made without departing from the concept and scope of the present utility model should be regarded as within the protection scope of the present utility model.

[0039] In the description of this specification, specific features, structures, materials, or characteristics can be combined in a suitable manner in any one or more embodiments or examples.

[0040] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model.
