[0023] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0024] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention 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 therefore cannot be understood as a limitation on the present invention.

[0025] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] Example 1

[0028] From above Figure 1-4 It can be seen that the large gantry-type lifting and transportation device designed in this embodiment includes a fixed support frame 1, a transmission system 2, a support pulley (support sprocket) 3, a lateral guide bracket 4, a counterweight guide bracket 5, a counterweight 6, a guide wheel 7, an end guide bracket 8, a lifting frame 9, a drive roller assembly 10, and a slab 11.

[0029] The fixed support frame 1 is used as a supporting component of the structure and is welded with steel sections.

[0030] 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 drive pulley (drive sprocket) and a wire rope (chain). One end of the 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 on the other hand to ensure the extreme position accuracy of the lifting frame 9.

[0031] The supporting pulley (supporting sprocket) 3 serves as an auxiliary adjustment mechanism, which can control the wrap angle between the steel wire rope (chain) and the driving pulley (driving sprocket) in the transmission system, and can also adjust the connection position of the counterweight 6.

[0032] The main function of the counterweight block 6 is to save energy. The weight selection of the counterweight block 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, the total weight of the lifting frame 9 and the driving roller assembly 10 and half of the maximum slab weight are usually taken as the total weight of the counterweight.

[0033] The counterweight guide bracket 5 is used to constrain the position of the counterweight 6 to ensure that the counterweight 6 does not swing during the lifting process. The guide wheels 7 are respectively installed on the side and end of the lifting frame 9 to limit the lifting process.

[0034] The lateral guide bracket 4 and the end guide bracket 8 are respectively installed on the side and end of the lifting frame 9, and serve as the slideway of the guide wheel 7, and work together with the guide wheel 7 to constrain the position of the lifting frame 9. A plurality of driving roller assemblies 10 are installed on the lifting frame 9. In the high position, the slab 11 is received by the driving roller; after being lowered to the low position, the slab 11 is transported away by the driving roller, and finally the lifting and transportation goal of the slab 11 is achieved.

[0035] Compared with the previous lifting roller, the lifting and transporting device of the present invention has larger size, heavier transport weight and higher lifting distance. The present invention has simple and practical structure, convenient maintenance, energy saving and reliability, perfect functions, and takes structural optimization and cost control into consideration, and has strong market competitiveness.

[0036] The present invention is described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of ordinary technicians in the field without departing from the purpose of the present invention. Many other changes and modifications that do not depart from the concept and scope of the present invention should be regarded as the protection scope of the present invention.

[0037] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0038] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
