[0026] To illustrate the technical content, structural features, achieved objectives, and effects of the application in detail, the technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. In the following description, for illustrative purposes, numerous specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in one or more equivalent arrangements. Furthermore, the various exemplary embodiments may differ, but are not necessarily exclusive. For example, the specific shape, structure, and characteristics of the exemplary embodiments may be used or implemented in another exemplary embodiment without departing from the inventive concept.

[0027] This application provides an ultra-wide movable lifting platform device for carrying unwound ultra-wide products and removing them from the winding equipment. It is highly automated and saves time and effort.

[0028] like Figure 1As shown, the lifting platform device includes: a movable base 10, a lifting platform 20, and a lifting mechanism 30. The bottom of the movable base 10 is also provided with a moving mechanism 40, which can reciprocate in the front-back direction to remove ultra-wide products from the winding equipment.

[0029] like Figure 1-5 As shown, the moving mechanism 40 includes a moving gear 1 rotatably mounted on the moving base 10, a moving rack 2 extending in the front-rear direction, and a moving motor 3 that is connected to the moving gear 1 in a transmission manner. The moving motor 3 is used to drive the moving gear 1 to rotate relative to the moving base 10 around its own axis. The moving gear 1 meshes with the moving rack 2. When the moving gear 1 rotates, the moving rack 2 interacts with the moving gear 1, so that the moving base 10 can move back and forth along the moving rack 2 with the moving gear 1.

[0030] The moving mechanism 40 also includes several moving wheels 4 and a moving guide rail 5 extending in the front-back direction. The several moving wheels 4 are rotatably mounted on the bottom of the moving base 10 and cooperate with the moving guide rail 5 to be able to roll back and forth along the moving guide rail 5. The cooperation between the moving wheels 4 and the moving guide rail 5 guides the moving direction of the moving base 10.

[0031] A first photoelectric switch 6 is installed on the movable base 10, and the first photoelectric switch 6 is connected to the moving motor 3. The first photoelectric switch 6 is used to detect the current position of the movable base 10, thereby improving the accuracy of the movable base 10's positioning on the moving guide rail 5.

[0032] The lifting platform 20 is arranged above the movable base 10 and can move back and forth in the vertical direction relative to the movable base 10. A limiting groove 7 extending in the left and right direction is provided on the upper surface of the lifting platform 20. The unwound ultra-wide products can be placed in the limiting groove 7, and the limiting groove 7 effectively prevents the ultra-wide products from falling off the lifting platform 20.

[0033] like Figure 1 , 4As shown in Figures 6 and 7, the lifting mechanism 30 is driven between the lifting platform 20 and the movable base 10 to drive the lifting platform 20 to move vertically. Since the lifting platform device of this application is suitable for ultra-wide products, and ultra-wide products have a large lateral dimension, the lifting mechanism 30 of this application includes a pair of lifting components 8 arranged opposite each other to stably and balancedly lift the ultra-wide products. Each lifting component 8 includes a pair of cross frames 81 and a lifting cylinder 82 drivenly connected to the pair of cross frames 81. The pair of cross frames 81 are arranged opposite each other in the front-back direction and are both configured to fold vertically. The upper and lower ends of each cross frame 81 are connected to the lifting platform 20 and the movable base 10, respectively. The lifting cylinder 82 drives the pair of cross frames 81 to fold synchronously, thereby enabling the lifting platform 20 to move vertically relative to the movable base 10. A synchronous connecting rod 9 is driven between the pair of lifting components 8, ensuring that the pair of lifting components 8 can fold synchronously, thereby ensuring that the lifting platform 20 can move horizontally.

[0034] Each cross frame 81 includes cross rods 811 and 812 that are hinged to each other. The upper end of the cross rod 811 is rotatably connected to the lifting platform 20, and its lower end is rotatably and slidably connected to the movable base 10. The upper end of the cross rod 812 is rotatably and slidably connected to the lifting platform 20, and its lower end is rotatably connected to the movable base 10.

[0035] A first guide mechanism 11 is provided between the movable base 10 and the crossbar 811. The first guide mechanism 11 includes a first guide seat 111 and a first guide wheel 112. The first guide seat 111 is fixedly installed on the movable base 10, and the first guide wheel 112 is rotatably installed on the lower end of the crossbar 811. A guide groove extending in the left-right direction is formed in the first guide seat 111. The first guide wheel 112 cooperates with the guide groove of the first guide seat 111 and can move left and right along the guide groove. A second guide mechanism 12 is provided between the lifting platform 20 and the crossbar 812. The second guide mechanism 12 includes a second guide seat 121 and a second guide wheel 122. The second guide seat 121 is fixedly installed on the bottom of the lifting platform 20, and the second guide wheel 122 is rotatably installed on the upper end of the crossbar 812. A guide groove extending in the left-right direction is also formed in the second guide seat 121. The second guide wheel 122 cooperates with the guide groove of the second guide seat 121 and can move left and right along the guide groove. When the cross frame 81 is folded, the first guide mechanism 11 and the second guide mechanism 12 provide guidance for the rotation of the cross rod 811 and the cross rod 812 respectively, and can effectively control the levelness of the lifting platform 20 during the lifting process, enhance the load-bearing stability, and prevent the lifting platform 20 from overturning.

[0036] Each lifting assembly 8 is equipped with a second photoelectric switch 13, which is signal-connected to the lifting cylinder 82 of the corresponding lifting assembly 8. The second photoelectric switch 13 is installed on the guide seat of the corresponding lifting assembly 8. By adjusting the position of the second photoelectric switch 13 on the guide seat, the lifting position of the lifting platform 20 can be effectively limited, and the positioning accuracy of the lifting platform 20 can be improved.

[0037] Several limiting posts 14 are also installed on the mobile base 10. Each limiting post 14 extends in the vertical direction and is located below the lifting platform 20, which protects the lifting platform 20.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application.
