Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] See Figures 1-5 As shown, a storage device for the heavy industry is schematically illustrated according to an embodiment of this application.

[0035] like Figure 1As shown, the storage equipment includes a base 1, a support frame 2, a placement rack 3, a fixing plate 4, and a fixing assembly. The support frame 2 is positioned on top of the base 1, with each support frame 2 having one base 1. The support frame 2 includes two symmetrically arranged sets of uprights, each set consisting of two symmetrically arranged uprights. The placement rack 3 is located between the two sets of uprights, and each placement rack 3 has two fixing plates 4 at both ends. The placement rack 3 is fixedly connected to the fixing plates 4, and this connection can be achieved by welding, but is not limited to welding. The fixing plates 4 are detachably connected to the support frame 2 via a fixing assembly, which includes a plug rod 6 and a fixing sleeve 7.

[0036] The two symmetrically arranged columns are connected by a reinforcing frame 13 to enhance the overall structural stability and resistance to deformation.

[0037] Specifically, the local structure of the fixing plate 4 and the support frame 2 is as follows: Figure 2 As shown, each fixing plate 4 includes two first panels and one second panel. The two first panels are parallel, and the second panel is perpendicularly connected to the two first panels. The two first panels are fitted with the two side walls of the column, that is, the two first panels are attached to the side walls of the column. Each side wall of the column is provided with an adjustment hole 5, and each first panel is provided with a through hole. During installation, the center of the adjustment hole 5 is aligned with the center of the through hole of the first panel. The insertion rod 6 is inserted into the adjustment hole 5 and the through hole. The second panel is connected to the placement frame 3. The insertion rod 6 is detachably connected to the fixing sleeve 7. The insertion rod 6 passes through the adjustment hole 5 on the support frame 2 and the through hole on the fixing plate 4, and is inserted into the fixing sleeve 7.

[0038] Multiple adjustment holes 5 are arranged vertically on the side wall of each column. This storage equipment, through the connection of the support frame 2, the placement rack 3, and the fixing plate 4, combined with the multiple adjustment holes 5 arranged on the side wall of the support frame 2, and the detachable connecting rods 6 and fixing sleeves 7, allows the height of the placement rack 3 to be flexibly adjusted according to actual needs. This solves the problem of fixed height and poor adaptability of existing placement racks 3, significantly improving the storage equipment's adaptability to different workpiece specifications, thus facilitating efficient operation in changing storage environments.

[0039] More specifically, the disassembled structure of the insertion assembly is as follows: Figure 3 As shown, the insertion assembly includes an insertion rod 6 and a fixing sleeve 7. When the fixing plate 4 is fixedly connected to the support frame 2 using the insertion assembly, the insertion rod 6 can pass through the adjustment hole 5 on the support frame 2 and the through hole on the fixing plate 4, and be inserted into the fixing sleeve 7.

[0040] In some embodiments, the cross-sectional structure of the fixing sleeve 7 is as follows: Figure 4As shown, the fixed sleeve 7 is provided with an abutment plate 9 and a connecting plate 10. The fixed sleeve 7 is fitted with a sliding sleeve 12. One end of the abutment plate 9 is hinged to the inner wall of the fixed sleeve 7 and the other end is hinged to one end of the connecting plate 10. The sliding sleeve 12 is provided with a connecting part that extends into the fixed sleeve 7 and is hinged to the other end of the connecting plate 10. The fixed sleeve 7 is provided with a sliding groove 11 for the connecting part to pass through. The sliding sleeve 12 slides along the axial direction of the fixed sleeve 7 and drives the abutment plate 9 and the connecting plate 10 to rotate so that the abutment plate 9 engages with or disengages from the insertion rod 6.

[0041] Furthermore, the abutment plate 9 and the connecting plate 10 are hinged by a snap-fit ​​block. The end of the insert rod 6 that snaps into the fixing sleeve 7 is provided with a slot 8 that mates with the snap-fit ​​block. The snap-fit ​​block also serves as the hinge axis between the abutment plate 9 and the connecting plate 10. The abutment plate 9 and the connecting plate 10 can be multiple sets evenly distributed along the circumference of the fixing sleeve 7, and the slots 8 can be multiple sets evenly distributed along the circumference of the insert rod 6. When the snap-fit ​​block is engaged with the slot 8, the angle between the abutment plate 9 and the connecting plate 10 is small. When the sliding sleeve 12 slides along the axial direction of the fixing sleeve 7 and drives the abutment plate 9 and the connecting plate 10 to rotate, the angle between the abutment plate 9 and the connecting plate 10 increases, and the snap-fit ​​block moves away from the insert rod 6 until it separates from the slot 8.

[0042] This storage equipment utilizes a plug-in assembly structure where the plug rod 6 and the fixed sleeve 7 cooperate. By employing the outer slot 8, the inner hinged abutment plate 9 and connecting plate 10, and the sliding groove 11 and sliding sleeve 12 provided along the outer wall of the fixed sleeve 7, the plug rod 6 can achieve quick and secure engagement and release after being inserted into the adjustment hole 5. This simplifies the fixing and disassembly operations of the plug-in components during the adjustment process, improves structural stability and assembly / disassembly efficiency, avoids cumbersome tool use and multi-step operations, and adapts to the frequent adjustment work requirements in the heavy industry.

[0043] Furthermore, the insertion rod 6 is provided with an adapter block 14, and the fixing sleeve 7 is provided with an adapter hole 15. The adapter block 14 is located at the end below the slot 8 away from the fixing sleeve 7, and the adapter block 14 and the adapter hole 15 cooperate with each other.

[0044] Furthermore, the adapter block 14 and the adapter hole 15 are polygons with the same shape along the radial cross section of the fixing sleeve 7. The purpose of setting both the adapter block 14 and the adapter hole 15 as polygons is to limit the relative circumferential rotation of the insertion rod 6 and the fixing sleeve 7, ensure that the connection between the insertion rod 6 and the fixing sleeve 7 is firm, avoid unstable rotation or positional displacement of the insertion rod 6, and prevent loosening due to vibration or impact during use.

[0045] Furthermore, one end of the insertion rod 6 is provided with a limiting part, the outer diameter of which is larger than the diameter of the through hole and the adjustment hole 5.

[0046] In some embodiments, the external structure of the fixing sleeve 7 is as follows: Figure 5As shown, a connecting sleeve 16 is fixedly connected to the outside of the sliding sleeve 12. A mounting block 17 is provided on the connecting sleeve 16, and an arc-shaped rod 18 is connected to the mounting block 17. The mounting block 17 and the arc-shaped rod 18 can be two or more sets evenly distributed along the circumference of the connecting sleeve 16.

[0047] A rotating sleeve 19 is also provided on the outside of the fixed sleeve 7. The rotating sleeve 19 can rotate circumferentially relative to the fixed sleeve 7. The arc-shaped rod 18 is coaxial with the rotating sleeve 19. A limit rod 20 is fixed on the outer wall of the rotating sleeve 19. The limit rod 20 is provided with an insertion hole 21 for the arc-shaped rod 18 to pass through. The arc-shaped rod 18 is inserted into the insertion hole 21 to lock the connecting sleeve 16. The arc-shaped rod 18 is separated from the insertion hole 21 to release the lock on the connecting sleeve 16.

[0048] The ends of the arc-shaped rod 18 away from the mounting block 17 and both ends of the insertion hole 21 are provided with rounded corners to reduce the frictional resistance when the arc-shaped rod 18 is inserted into the insertion hole 21, so as to facilitate the smooth cooperation of the limiting mechanism.

[0049] The external part of the fixed sleeve 7 is connected to the arc rod 18 on the mounting block 17 and the insertion hole 21 on the limiting rod 20, which can realize the flexible switching between the adjustment state and the fixed state of the fixed sleeve 7. That is, the posture of the internal components of the fixed sleeve 7 can be locked and unlocked to improve the operation efficiency and safety during the adjustment process. This design can achieve precise positioning and fixation during the adjustment process, and avoid structural instability or accidental loosening.

[0050] Furthermore, such as Figure 5 As shown, a positioning sleeve 22 is fixedly connected to one axial end of the rotating sleeve 19 and sleeved outside the fixed sleeve 7. A sliding groove 23 is provided on the inner wall of the positioning sleeve 22. An elastic element 24 and a positioning block 25 are provided in the sliding groove 23. One end of the elastic element 24 is connected to the bottom surface of the sliding groove 23 and the other end is connected to the positioning block 25. A plurality of positioning grooves 26 that cooperate with the positioning block 25 are provided on the outer wall of the fixed sleeve 7. The plurality of positioning grooves 26 are arranged along the circumference of the fixed sleeve 7. The positioning sleeve 22 rotates under force so that the positioning block 25 slides along the sliding groove 23 and the elastic element 24 undergoes elastic deformation.

[0051] Among them, the elastic element 24 can be a compression spring. The elastic element 24 provides an elastic force along the radial direction of the fixed sleeve 7 to the positioning block 25, so as to elastically press the positioning block 25 into the corresponding positioning groove 26.

[0052] The design of the positioning sleeve 22 and its components enables elastic locking of the angular position of the rotating sleeve 19, precise positioning control of the rotating sleeve 19, and thus limit the rotation of the rotating sleeve 19 to prevent accidental rotation and instability. While ensuring a firm connection, it makes the operation during height adjustment safer and more reliable, effectively enhancing the operational stability and long-term reliability of the entire storage equipment.

[0053] In this design, the outer wall of the positioning block 25 near the positioning groove 26 is arc-shaped, as is the positioning groove 26. The arc-shaped outer walls of multiple sets of positioning blocks 25 and positioning grooves 26 enhance the fit accuracy between the positioning blocks 25 and positioning grooves 26, reduce wear, and ensure that the rotating sleeve 19 remains stable and smooth during adjustment. For example, the positioning block 25 can be spherical, and the positioning groove 26 can be a hemispherical shape matching the positioning block 25.

[0054] The operation process of the storage equipment provided in this embodiment during operation is described below.

[0055] Since the multiple sets of placement racks 3 of this storage equipment are used to place and store workpieces, when the height of the placement racks 3 needs to be adjusted, the insertion rod 6 and the fixing sleeve 7 need to be inserted and removed. Rotating the rotating sleeve 19 drives the multiple sets of limiting rods 20 to rotate, causing the multiple sets of limiting rods 20 to drive the insertion hole 21 to disengage from the arc rod 18, thereby releasing the limitation on the connecting sleeve 16. Pushing the connecting sleeve 16 to drive the sliding sleeve 12 to slide along the multiple sets of sliding grooves 11, the sliding sleeve 12 drives the multiple sets of connecting plates 10 and abutment plates 9 to rotate, thereby causing the multiple sets of snap-fit ​​blocks to disengage from their respective snap-fit ​​slots 8, releasing the snap-fit ​​on the insertion rod 6. Then, the fixing sleeve 7 is removed from the insertion rod 6, and the insertion rod 6 is pulled out of the adjustment hole 5, thereby releasing the fixation on the fixing plate 4.

[0056] Then, the height of the placement rack 3 is adjusted by selecting the adjustment hole 5. After the adjustment is completed, the insertion rod 6 is inserted into the selected adjustment hole 5 and connected to the fixing plate 4. The fixing sleeve 7 is inserted into the top of the insertion rod 6. The connecting sleeve 16 is pulled to drive the sliding sleeve 12 to slide along the multiple sets of sliding grooves 11. The sliding sleeve 12 pushes the multiple sets of connecting plates 10 and abutment plates 9 to rotate, so that the multiple sets of locking blocks are engaged in their respective corresponding slots 8 to lock the insertion rod 6.

[0057] Finally, rotating the rotating sleeve 19 drives multiple sets of limiting rods 20 to rotate, causing multiple sets of insertion holes 21 to engage with the arc-shaped rods 18, thereby limiting the connection sleeve 16. When the rotating sleeve 19 rotates, a certain amount of torque is applied, causing multiple sets of positioning blocks 25 to slide out of their respective positioning grooves 26. These positioning blocks 25 slide radially along the positioning sleeve 22 within the sliding groove 23, pressing against the elastic element 24. When the rotating sleeve 19 stops rotating, the elastic elements 24 elastically recover, pushing their respective positioning blocks 25 to slide along the sliding groove 23 and abut against the corresponding positioning groove 26, thus positioning and fixing the rotating sleeve 19.

[0058] Based on the various embodiments of this application described above, in the absence of explicit denial or conflict, the technical features of one embodiment may be advantageously combined with one or more other embodiments.

[0059] The above descriptions are merely some embodiments of this application, used only to illustrate the technical solutions of this application, and not to limit it. It should be understood that those skilled in the art can make improvements or substitutions based on the above descriptions without departing from the inventive concept of this application, and all such improvements and substitutions should fall within the protection scope of this application. In this case, all details can be replaced with equivalent elements, and materials, shapes, and sizes can also be arbitrary.
