[0020] A stacker crane is a device used in automated storage and retrieval systems (AS / RS) for vertical lifting and horizontal transport of goods. It is typically installed within the aisles of the AS / RS to enable rapid storage and retrieval of goods within the warehouse.

[0021] Cable carriers on stacker cranes are used to protect the crane's cables, air hoses, and other components from damage during crane movement. Cable carriers can wobble during movement, and while existing technologies often use cable carrier grooves to secure them, inertia can still cause issues, especially with taller or faster stacker cranes, leading to skewing, jamming, and damage during lifting and lowering, thus affecting cargo handling.

[0022] In view of this, this application proposes a cable chain anti-sway mechanism to solve the above problems.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the various embodiments of this application will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of this application to enable the reader to better understand this application. However, the technical solutions claimed in this application can be implemented even without these technical details and various changes and modifications based on the following embodiments.

[0024] In the following description, certain specific details are set forth for the purpose of illustrating various disclosed embodiments in order to provide a thorough understanding of the various disclosed embodiments. However, those skilled in the art will recognize that embodiments may be practiced without one or more of these specific details. In other instances, well-known apparatuses, structures, and techniques associated with this application may not have been shown or described in detail to avoid unnecessarily obscuring the description of the embodiments.

[0025] Unless the context requires otherwise, throughout the specification and claims, the word “comprising” and its variations, such as “including” and “having”, shall be understood to have an open, inclusive meaning, that is, to be interpreted as “including, but not limited to”.

[0026] The embodiments of this application will be described in detail below with reference to the accompanying drawings to provide a clearer understanding of the purpose, features, and advantages of this application. It should be understood that the embodiments shown in the drawings are not intended to limit the scope of this application, but are merely for illustrating the essential spirit of the technical solution of this application.

[0027] Throughout this specification, references to "an embodiment" or "an embodiment" indicate that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Therefore, the appearance of "in an embodiment" or "an embodiment" in various places throughout the specification does not necessarily refer to the same embodiment. Furthermore, a particular feature, structure, or characteristic may be combined in any manner in one or more embodiments.

[0028] Specifically, such as Figure 1 As shown, this application proposes a cable chain anti-sway mechanism, comprising:

[0029] Stacker crane column 1,

[0030] Cable chain guide groove 2, located on one side of the stacker crane column 1, is used to place a cable chain thereon.

[0031] The accompanying bracket 3 is located above the cable chain guide groove 2 and can be driven by the cable chain to move up and down.

[0032] The guide mechanism 4 is located at the connection between the accompanying bracket 3 and the drag chain guide groove 2.

[0033] The stacker crane column 1 is a sturdy column structure set vertically. It mainly supports the overall weight of the stacker crane as well as various equipment and mechanisms. At the same time, it provides guide rails for the lifting and lowering movement of the stacker crane, ensuring the stable operation of the stacker crane in the vertical direction and ensuring that goods can be accurately stacked and transported to the designated location.

[0034] The cable chain guide groove 2 provides a fixed insertion space and guide path for the cable chain, which can constrain the movement range of the cable chain, so that the cable chain moves along a predetermined track during the operation of the stacker crane, reducing the swing amplitude of the cable chain and reducing the risk of the cable chain colliding or getting tangled with other components.

[0035] The accompanying bracket 3 is installed above the cable chain guide groove 2 and connected to the cable chain. It moves up and down with the movement of the cable chain, serving to support and guide the cable chain and other related connecting components, ensuring the stability of the cable chain during movement, and also providing a support point for the installation and connection of other equipment or components.

[0036] The guide mechanism 4 is located at the connection point between the traveling bracket 3 and the cable chain guide groove 2, and is a device that guides and constrains the movement of the traveling bracket 3 and the cable chain. It can limit the displacement of the traveling bracket 3 and the cable chain in non-predicted directions, ensure their straightness and stability during up and down movement, and reduce malfunctions and safety hazards caused by swaying or deviation.

[0037] This application, through the synergistic action of the cable chain guide groove 2, the accompanying support 3, and the guiding mechanism 4, effectively constrains the movement trajectory of the cable chain, reducing swaying and tilting during stacker crane operation. This makes the stacker crane more stable when lifting and horizontally transporting goods, reducing the risks of goods shifting or colliding due to cable chain swaying, improving the overall operational stability of the stacker crane, and ensuring the safety and accuracy of goods transportation. It can adapt to complex, high-speed working environments, expanding the application range of stacker cranes and improving the overall performance and efficiency of automated warehouses.

[0038] Furthermore, such as Figure 2 As shown, the upper part of the traveling bracket 3 is provided with an inclined surface 31. The inclined surface 31 is inclined at a certain angle relative to the drag chain guide groove 2. The main purpose is to prevent the drag chain from rubbing against the upper part of the traveling bracket 3 during the upward operation of the stacker crane, and to ensure that the drag chain can slide smoothly in the guide groove, thereby reducing drag chain wear and equipment failure caused by rubbing.

[0039] Furthermore, the lower part of the accompanying bracket 3 is provided with an arc end 32, which fits against the cable chain, thereby better guiding the movement direction of the cable chain, while reducing the resistance and local stress concentration experienced by the cable chain during movement, further improving the stability and service life of the cable chain.

[0040] Furthermore, the cable chain guide groove 2 is Z-shaped, which facilitates the guidance of the cable chain and the sliding track that serves as the accompanying support 3.

[0041] Furthermore, a counterweight 5 is also fixed on the accompanying support 3.

[0042] Furthermore, the counterweight 5 may consist of one or more pieces, and when there are multiple pieces, adjacent counterweights 5 may be stacked.

[0043] Furthermore, the accompanying bracket 3 is provided with a vertical support rod 33, and the counterweight 5 is provided with a hole through which the support rod 33 passes, and is fixed to the support rod 33 by the upper nut.

[0044] Preferably, two support rods 33 are provided and fixed at the arc end 32. This is to better fix the counterweight 5 during vertical movement.

[0045] Furthermore, the guiding mechanism 4 includes a first guiding mechanism and a second guiding mechanism distributed on the left and right sides. Both the first guiding mechanism and the second guiding mechanism include horizontal and vertical guide wheels. The horizontal guide wheels are located at the top and bottom, contacting and sliding along the stacker column 1. The vertical guide wheels are located in the middle, contacting and sliding along the drag chain guide groove 2, so as to ensure the mobility and reliability of the accompanying support 3.

[0046] The anti-sway mechanism for cable chains provided in the embodiments of this application has been described in detail above. The various embodiments in the specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since it corresponds to the method disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to in the method section. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
