Description

Technical Field

[0001] This utility model relates to a flexible guiding structure, and in particular to a flexible guiding structure for automated storage racks. Background Technology

[0002] Automated storage racks use guide rails to connect pallets. The pallets move on the guide rails via guide wheels and a transmission structure. Due to the height of the racks, there is a deviation between the top and bottom of the guide rails. If fixed guide wheels are used, the guide wheels may get stuck or disengage from the guide rails as the distance between the guide rails changes during the pallet's up-and-down movement, causing the pallet to shake or even disengage from the guide rails. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, this utility model provides a flexible guide structure that can adapt to the error of the guide rail spacing and ensure the stability of the tray connected to the guide structure on the guide rail.

[0004] To achieve this objective, the structure adopted by this utility model is: a flexible guiding structure, including a main body, with guide wheel sets at the upper and lower ends of the main body, the guide wheel sets including a swing arm, one end of the swing arm being connected to the main body, and the other end being provided with a guide wheel, a pad and a nut being connected to the end of the main body by bolts, a spring assembly being provided between the pad and the nut, and the swing arm being connected to the pad.

[0005] The spring assembly includes a compression spring and multiple disc springs, with the disc springs positioned in the gaps between the compression springs.

[0006] Its beneficial effects are: the structure of this utility model is reasonably and ingeniously designed. When the distance between the guide rails changes during the movement of the main body along the guide rail, the guide wheel can always be in contact with the guide rail under the action of the spring group, so as to avoid the guide wheel from separating from the guide rail and ensure the stable movement of the device connected to the guide structure on the guide rail. Attached Figure Description

[0007] This utility model will be described by way of example and with reference to the accompanying drawings, wherein:

[0008] Figure 1 This is a three-dimensional structural diagram of the present invention;

[0009] Figure 2 This is the formal structural diagram of this utility model. Detailed Implementation

[0010] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0011] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0012] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components; a fixed connection can be welding or adhesive bonding. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0013] like Figure 1 , Figure 2 The flexible guide structure shown includes a main body 1, with guide wheel assemblies symmetrically arranged at both ends of the main body 1. Each guide wheel assembly includes a swing arm 2, with a connecting ear at one end of the swing arm 2 connected to the main body 1 via a pin, and the other end connected to a guide wheel 3. A screw 6 is arranged between the main body 1 and the guide wheel 3, with one end of the screw 6 fixed to the main body 1 and the other end fitted with a pad 4 and a nut 7. A spring assembly 5 is arranged between the nut 7 and the pad 4, and the pad 4 is connected to the swing arm 2. Two guide rails are symmetrically arranged, and the device between the guide rails is connected to the guide rails on both sides via a flexible guide structure. The distance between the guide rails may change due to installation errors at different positions. When the guide wheel 3 is subjected to pressure, the swing arm 2 swings, and the spring assembly 5 is deformed under pressure, keeping the guide wheel 3 in contact with the guide rail it mates with. The device can then move stably along the guide rail without derailing.

[0014] The spring assembly 5 includes a compression spring and multiple disc springs. The disc springs are placed in the gaps between the compression springs to enhance the compressive strength of the spring assembly 5 and prevent fatigue deformation of the spring assembly 5.

[0015] One end of the nut 7 abuts against the spring assembly 5 to prevent it from disengaging from the screw, and the other end is connected to the screw via a thread. The pressure of the spring assembly 5 can be adjusted by adjusting the position of the nut 7 on the screw, thereby adjusting the pressure between the guide wheel 3 and the guide rail.

[0016] Based on the above description and inspired by this utility model, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
