Description

Technical Field

[0001] This utility model relates to the field of metallurgical equipment technology, specifically to an integrated device for three-dimensional storage and rapid positioning and disassembly of extrusion rollers. Background Technology

[0002] In the cold-rolled strip steel production process, squeeze rolls are one of the key spare parts of the pickling mill, used to squeeze the acid from the surface of the strip steel. They require regular replacement and maintenance. Currently, in the cold rolling mills of many domestic steel companies, such as Jinsteel Group, the storage and management of squeeze rolls generally adopts the traditional ground stacking method. This method has the following significant drawbacks:

[0003] Disorganized storage and inefficient management: New and old squeeze rollers are mixed together and stacked, taking up a lot of floor space. Operators have difficulty quickly distinguishing between "usable" and "unusable" rollers, and it takes an average of 20 minutes to find and retrieve the required spare parts, which seriously affects the efficiency of equipment maintenance and the continuous operation rhythm of the production line.

[0004] Significant safety hazards exist: the stacked rollers lack effective fixing and isolation measures, resulting in extremely poor stability and a risk of slipping and rolling, posing a serious threat to the personal safety of on-site workers. Furthermore, during hoisting operations, the confined space and the rollers' susceptibility to collisions greatly increase the risk of equipment damage or personal injury accidents.

[0005] The working environment is harsh: oil stains generated during disassembly and assembly cannot be cleaned up in a timely manner and are mixed with the storage area, resulting in a dirty and messy on-site environment that does not meet the requirements of modern enterprise safety production and 6S standardized management.

[0006] It can easily lead to operational errors: Due to the lack of clear markings and positioning, when changing rollers, operators are very likely to mistakenly use damaged old rollers or rollers of incompatible specifications, resulting in equipment rework, which not only increases labor intensity but also affects product quality.

[0007] A search revealed no existing technology that can effectively solve the aforementioned problems. Therefore, there is an urgent need for a specialized device integrating three-dimensional storage, rapid positioning, and safe assembly / disassembly to achieve standardized, efficient, and safe management of the squeeze rollers, thereby improving equipment support capabilities and on-site management levels. Utility Model Content

[0018] In a preferred embodiment of the integrated device for three-dimensional storage and rapid positioning and disassembly of extrusion rollers according to this utility model, the spacing between the support plates along the height direction of the connecting plate is 300-500mm, and the number of support plates on both sides of each connecting plate is 3-5 sets.

[0019] As a preferred embodiment of the integrated device for three-dimensional storage and rapid positioning and disassembly of extrusion rollers according to this utility model, the reinforcing rib is made of Q235 high-strength steel and the inclination angle with the base is 45°-60°.

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0033] Please see Figure 1-5 A three-dimensional storage and rapid positioning and disassembly integrated device for squeeze rollers, comprising:

[0034] Base 1 has a rectangular frame structure;

[0035] Several pairs of longitudinal frames 2 are arranged vertically and symmetrically along the length of the base 1, and a connecting rod 3 is provided between the tops of each pair of longitudinal frames 2;

[0036] The spacing of the longitudinal frame 2 is configured to form at least one first slot 4 and a plurality of second slots 5;

[0037] The longitudinal frame 2 includes a connecting plate 6 and baffle frames 7 symmetrically fixed on the front and rear sides of the connecting plate 6. Multiple sets of support plates 8 are provided at equal intervals along the height direction on both sides of the connecting plate 6, and the two sides of the support plates 8 are fixedly connected to the baffle frames 7.

[0038] The detachable shelf 9 has its two ends attached to the support plates 8 of the adjacent longitudinal frames 2 at the front and rear.

[0039] The reinforcing ribs 10 are inclined and fixed on the left and right sides and front and rear ends of the base 1, and are fixedly connected to the outermost longitudinal frame 2.

[0040] In this embodiment: the rectangular frame base 1 provides stable support, and the symmetrical longitudinal frames 2 form an overall frame through the top connecting rod 3. The reinforcing ribs 10 at the edge of the base 1 distribute the edge force to prevent the device from deforming or overturning. The I-shaped structure of the longitudinal frame 2 provides an installation base for the support plate 8 and restricts the lateral displacement of the squeeze roller through the baffle frame 7 to prevent slippage. Through the differentiated spacing design of the longitudinal frame 2, a first slot 4 of 1900mm and a second slot 5 of 700mm are formed to achieve physical isolation between new and old rollers. The support plate 8 and the detachable shelf 9 cooperate to form a multi-layer storage space (3-5 layers, layer spacing 300-500mm), making full use of vertical space and improving storage utilization. The identification plate 11 on the outside of the longitudinal frame 2 clearly marks the roller type (new / old) and specifications corresponding to the slot. Operators can quickly locate the target spare parts without checking the status of each roller. Combined with the orderly operation logic of "picking up material from the upper layer and storing material from the lower layer", the retrieval time is further shortened.

[0041] As a technical optimization of this utility model, the first slot 4 is formed by a distance of 1900mm between two adjacent longitudinal frames 2, and is used to place an old squeeze roller alone; the second slot 5 is formed by a distance of 700mm between two adjacent longitudinal frames 2, and is used to place new squeeze rollers side by side.

[0042] In this embodiment: the spacing design of the longitudinal frame 2 distinguishes the storage areas of different types of squeeze rollers, realizing the physical isolation and classified storage of new and old squeeze rollers. The baffle frame 7 effectively prevents the squeeze rollers from slipping. The support plate 8 realizes layered storage, improves space utilization, avoids mixing, and matches the slot space according to the usage requirements of new and old rollers (old rollers may need to be inspected separately, and new rollers need to be used in pairs), thereby improving the rationality of storage and management efficiency.

[0043] As a technical optimization of this utility model, the width of the detachable shelf 9 is adapted to the distance between the front and rear baffle frames 7, so that when the two ends of the detachable shelf 9 are attached to the support plate 8, its side is in contact with or gap-fitted with the inner side of the baffle frame 7.

[0044] In this embodiment: it ensures that the detachable shelf 9 will not sway laterally after being overlapped, thereby improving the shelf's load-bearing stability. At the same time, it avoids excessive gaps that could cause the squeeze roller to shift, or excessive gaps that could make it difficult to disassemble or assemble the shelf. This balances stability and ease of operation, thereby improving the overall structural stability of the device.

[0045] As a technical optimization of this utility model, the spacing of the support plates 8 along the height direction of the connecting plate 6 is 300-500mm, and the number of support plates 8 on both sides of each connecting plate 6 is 3-5 sets.

[0046] In this embodiment: the layer height is designed according to the diameter of the squeeze roll (the diameter of the conventional cold-rolled squeeze roll is suitable for this spacing range) to avoid insufficient layer height leading to roll collision or excessive height wasting space; 3-5 sets of support plates 8 can realize 3-5 layers of storage, taking into account both space utilization and overall load-bearing safety of the device, providing a stable placement platform for the squeeze roll and avoiding direct contact between the roll and the roll, which may cause damage.

[0047] As a technical optimization of this utility model, the reinforcing rib 10 is made of Q235 high-strength steel, and the inclination angle between it and the base 1 is 45°-60°.

[0048] In this embodiment: the reinforcing rib 10 can disperse the force at the connection between the base 1 and the longitudinal frame 2, preventing structural deformation of the device edge due to excessive load or external collision; it greatly enhances the overall rigidity and anti-overturning ability of the device, ensuring stability under full load; the Q235 steel ensures that the reinforcing rib 10 has sufficient strength, and the 45°-60° tilt angle is the mechanically optimal angle, which can maximize the dispersion of external forces (such as the device tilting trend and roller collision force), further reducing the risk of device deformation and overturning, and improving long-term reliability.

[0049] As a technical optimization of this utility model, it also includes an identification plate 11 located on the outside of the longitudinal frame 2. The identification plate 11 is marked with the type and specification information of the squeeze roller corresponding to the first slot 4 and the second slot 5.

[0050] In this embodiment: the identification plate 11 is used to clearly mark the type and specification of the squeeze roller stored in the corresponding slot, realize visual and standardized management, avoid misuse, solve the problems of slow search and misinstallation caused by the lack of identification in traditional storage, and operators can quickly locate the new or old roller of the required specification through the identification, shorten the retrieval time, eliminate the risk of misinstallation and rework, and at the same time comply with 6S management.

[0051] Working principle and usage process of this utility model:

[0052] Prioritize storing the bottom layer. Place the old squeeze rollers one by one into the first slot 4 with a spacing of 1900mm, ensuring that both ends of the roller body overlap with the front and rear support plates and that the sides are limited by the longitudinal frame 2 baffle frame 7. Place the new squeeze rollers two by two into the second slot 5 with a spacing of 700mm, again ensuring that the roller bodies overlap smoothly and the sides are properly limited. When all the bottom layer slots are full, attach the two ends of the detachable shelf 9 to the upper layer support plate 8, and repeat the bottom layer storage steps, storing the upper layer according to the rule of "old rollers into the first slot 4, new rollers into the second slot 5", until all the squeeze rollers to be stored are stored, or the maximum number of layers of the device (3-5) is reached. After storage, check whether the type and specifications of the roller body in the slot are consistent with the outer label 11 of the longitudinal frame 2, to ensure that the label is accurate and to provide clear guidance for subsequent retrieval; and the operator can quickly find the layer and position of the corresponding specification of the second slot 5 (new roller) or the first slot 4 (old roller, if it needs to be recycled for maintenance) by using the outer label 11 of the longitudinal frame 2.

[0053] When retrieving, prioritize retrieving the topmost roller. Use hoisting equipment (such as an overhead crane) to align with the target roller and lift it slowly, ensuring that the roller does not collide with the longitudinal frame 2 or adjacent rollers during the hoisting process. If all rollers in a certain slot of a layer have been retrieved, they can be left unprocessed until all slots in that layer are empty, then remove the corresponding detachable shelf 9. After all the topmost rollers have been retrieved and the shelf has been removed, retrieve the next layer of rollers in the same way, and so on downwards until the required number of target rollers have been retrieved. After retrieval, check whether the remaining rollers are still placed stably (without the risk of displacement or slippage), and verify that the identification plate 11 matches the remaining rollers to ensure that the storage status is orderly. If it is necessary to disassemble and install bearing seats on old rollers, the old rollers can be retrieved from the first slot 4 and placed in the disassembly and assembly area near the device (refer to the "disassembly and assembly area" design in the attached figure) to utilize the space around the device for operation (avoiding the operational difficulties caused by the narrow space during traditional stacking).
