Description

Technical Field

[0001] This application relates to the printing industry, and in particular to a cantilever beam reinforcement structure for a large plate roller storage and retrieval device. Background Technology

[0002] In the printing industry, traditional roller storage and retrieval equipment typically employs cantilever beam structures and lifting mechanisms. Specifically, patent document CN209455571U discloses gravure printing plate cylinder storage and retrieval equipment. The cantilever beam structure mainly includes a keel frame and a single cantilever beam structure. The lifting mechanism lifts the roller and moves directionally along the single cantilever beam. The cable of the lifting mechanism is tractioned and protected using nylon drag chains. However, due to the large size and weight of large plate rollers, traditional cantilever beam structures are prone to guide rail breakage after long-term use, leading to equipment damage and safety hazards. Utility Model Content

[0003] To enhance the cantilever beam structure, this application provides a cantilever beam reinforcement structure for a large-scale printing roller storage and retrieval device.

[0004] This application provides a cantilever beam reinforcement structure for a large-scale printing roller storage and retrieval device, which adopts the following technical solution:

[0005] A cantilever beam reinforcement structure for a large-scale printing roller storage and retrieval device includes:

[0006] First beam;

[0007] The second beam is set parallel to the first beam, and the hoisting mechanism is located between the first beam and the second beam, and is slidably connected to the first beam and the second beam;

[0008] The keel frame is symmetrically set at both ends of the first beam, and the two ends of the first beam are respectively connected to the two keel frames. The two ends of the second beam are respectively connected to the two keel frames.

[0009] By adopting the above technical solution, the parallel arrangement of the first beam and the second beam ensures that the force generated by the hoisting mechanism during operation is evenly distributed on the two beams, reducing the possibility of deformation or breakage caused by concentrated force on a single beam structure. At the same time, the double beam structure combined with the symmetrically designed keel frame further enhances the stability of the overall structure, ensuring the safety and reliability of the large plate roller storage and retrieval equipment in long-term use, and strengthening the cantilever beam structure.

[0010] Optionally, the second beam is provided with a weight-reducing groove, and the groove wall is connected to multiple support plates, which are equidistantly distributed along the length of the second beam.

[0011] By adopting the above technical solution, the weight-reducing groove effectively reduces the weight of the second beam. At the same time, the design of multiple support plates equidistantly distributed along the length of the second beam significantly improves the structural strength of the second beam. Thus, while ensuring the load-bearing capacity of the cantilever beam, the amount of material used is reduced, saving costs and achieving a balance between lightweight and high strength. Secondly, it provides space for the nylon cable chain, saving space.

[0012] Optionally, a first rod is connected to the bottom wall of the weight reduction tank. The first rod spans multiple support plates. A second rod is provided parallel to the first rod. The second rod is connected to the tank wall of the weight reduction tank. A connector is connected to the first rod. The end of the connector away from the first rod is connected to the second rod.

[0013] By adopting the above technical solution, the first rod spans multiple support plates, evenly distributing the stress borne by the support plates and reducing the possibility of structural failure caused by local stress concentration. The second rod is set parallel to the first rod and connected by connectors, further strengthening the structural strength of the weight reduction groove area and ensuring that the cantilever beam is not prone to deformation or breakage when bearing large printing rollers, thereby significantly improving the safety and reliability of the equipment.

[0014] Optionally, a third rod is connected to the bottom wall of the weight reduction tank. The third rod is located at the bottom of the second rod. The second rod is connected to a reinforcing member, and the end of the reinforcing member away from the second rod is connected to the third rod.

[0015] By adopting the above technical solution, the bottom wall of the weight-reducing trough is connected to the third rod, and the third rod is located at the bottom of the second rod, which makes the structure more evenly stressed and effectively disperses the load borne by the second rod. At the same time, the second rod and the third rod are connected by a reinforcement, which further enhances the connection strength between the two and improves the stability of the overall structure, thereby reducing the possibility of structural damage caused by stress concentration and extending the service life of the cantilever beam.

[0016] Optionally, a fourth rod is connected to the bottom wall of the weight reduction tank, and a first fixed frame is connected to the fourth rod. The end of the first fixed frame away from the fourth rod is connected to the first rod. A second fixed frame is connected to the first rod, and the end of the second fixed frame away from the first rod is connected to the top wall of the weight reduction tank. The first fixed frame and the second fixed frame abut against each other.

[0017] By adopting the above technical solution, the connection between the fourth rod and the first rod, and the top wall of the weight reduction groove, forms a stable frame structure, which further improves the overall strength and deformation resistance of the cantilever beam, and at the same time improves the stability of the hoisting mechanism during sliding.

[0018] Optionally, the support plate may have stress openings.

[0019] By adopting the above technical solutions, local stress can be effectively released, reducing the possibility of structural damage caused by stress concentration, thereby significantly improving the stability and service life of cantilever beam structures.

[0020] Optionally, the top of the keel frame is in the shape of an inverted U-shape with the opening facing upwards, and the two ends are connected to the first beam and the second beam respectively. A reinforcing beam is provided at the inverted opening of the keel frame, and the two ends of the reinforcing beam are connected to the inner walls on both sides of the inverted U-shape of the keel frame respectively.

[0021] By adopting the above technical solution, the top of the keel frame is designed as an upward-facing C-shaped frame, and a reinforcing beam is added at the C-shaped opening. This makes the stress on the cantilever beam structure more uniform, reducing the possibility of structural deformation or damage caused by local stress concentration. At the same time, the firm connection between the reinforcing beam and the inner wall of the keel frame further enhances the bending and torsional resistance of the overall structure, significantly improving the safety and reliability of the large-scale printing roller storage and retrieval equipment under high-intensity operating conditions.

[0022] Optionally, the two ends of the reinforcing beam are symmetrically connected with reinforcing rods, and the bottom of the reinforcing beam is provided with a reinforcing frame. The reinforcing frame is connected to the keel frame, and the end of the reinforcing rod away from the reinforcing beam is connected to the reinforcing frame.

[0023] By adopting the above technical solutions, the synergistic cooperation between the reinforcing beam, reinforcing rod, and reinforcing frame significantly improves the overall rigidity and deformation resistance of the cantilever beam structure, effectively disperses the concentrated stress generated during the hoisting and movement of large rollers, and further enhances the connection reliability between the cantilever beam and the main body of the equipment, thereby providing a solid guarantee for the long-term stable operation of the equipment.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The parallel arrangement of the first and second beams ensures that the force generated by the hoisting mechanism during operation is evenly distributed on the two beams, reducing the possibility of deformation or breakage caused by stress concentration in a single beam structure. At the same time, the double beam structure combined with the symmetrically designed keel frame further enhances the stability of the overall structure, ensuring the safety and reliability of the large plate roller storage and retrieval equipment in long-term use, and strengthening the cantilever beam structure.

[0026] 2. The weight-reducing groove effectively reduces the weight of the second beam, while the design of multiple support plates equidistantly distributed along the length of the second beam significantly improves the structural strength of the second beam. Thus, while ensuring the load-bearing capacity of the cantilever beam, the amount of material used is reduced, saving costs and achieving a balance between lightweight and high strength.

[0027] 3. The coordinated operation between the reinforcing beams, reinforcing rods, and reinforcing frames significantly improves the overall rigidity and deformation resistance of the cantilever beam structure, effectively disperses the concentrated stress generated during the hoisting and movement of large rollers, and further enhances the reliability of the connection between the cantilever beam and the main body of the equipment, thus providing a solid guarantee for the long-term stable operation of the equipment.

[0033] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0034] This application discloses a cantilever beam reinforcement structure for a large-scale printing roller storage and retrieval device.

[0035] Reference Figure 1 and Figure 2 A cantilever beam reinforcement structure for a large-scale printing roller storage and retrieval device includes a first beam 1, a second beam 2, and a keel frame 3. The length direction of the second beam 2 is parallel to the length direction of the first beam 1. A hoisting mechanism is located between the first beam 1 and the second beam 2 and is slidably connected to the first beam 1 and the second beam 2. The keel frame 3 is symmetrically arranged at both ends of the first beam 1, and both ends of the first beam 1 are connected to two keel frames 3 respectively. Both ends of the second beam 2 are connected to two keel frames 3 respectively, so that the force generated by the hoisting mechanism during operation is evenly distributed on the two beams, the first beam 1 and the second beam 2, reducing the possibility of deformation or breakage of the single beam structure due to force concentration or overload.

[0036] The top of the keel frame 3 is an upward-opening C-shaped frame, and the top walls at both ends are fixedly connected to the first beam 1 and the second beam 2 respectively. A reinforcing beam 31 is provided at the C-shaped opening of the keel frame 3. The two ends of the reinforcing beam 31 are fixedly connected to the inner walls on both sides of the C-shaped keel frame 3, thereby enhancing the connection structure at both ends of the top of the keel frame 3, reducing the possibility of splitting, and thus improving the movement stability of the hoisting mechanism.

[0037] The two ends of the reinforcing beam 31 are symmetrically fixedly connected with reinforcing rods 32, which are fixedly connected to the keel frame 3. The bottom of the reinforcing beam 31 is provided with a reinforcing frame 33, which is square in shape and fixedly connected to the keel frame 3. The end of the reinforcing rod 32 away from the reinforcing beam 31 is fixedly connected to the top of the reinforcing frame 33. This improves the overall rigidity and deformation resistance of the cantilever beam structure, helps to disperse the concentrated stress generated during the hoisting and movement of the large roller, and further enhances the reliability of the connection between the cantilever beam and the main body of the equipment, thus providing a solid guarantee for the long-term stable operation of the equipment.

[0038] Specifically, a rack 11 is fixedly connected to the top wall of the first beam 1, and the length direction of the rack 11 is parallel to the length direction of the first beam 1. A first guide rail 12 is provided parallel to one side of the rack 11. The hoisting mechanism includes a housing 4, a drive motor, and a gear. The housing 4 is slidably connected to the first guide rail 12. The drive motor is fixedly connected to the housing 4, and the output end of the drive motor is fixedly connected to the gear. The gear meshes with the rack 11. A second guide rail 21 is fixedly connected to the top wall of the second beam 2. A third guide rail 22 is provided parallel to the second guide rail 21. The first guide rail 12 and the second guide rail 21 are located between the rack 11 and the third guide rail 22. When the drive motor is started, the drive motor drives the gear to rotate. Through the meshing relationship, the gear drives the hoisting mechanism to move along the length direction of the rack 11, thereby driving the hoisting mechanism to move under the support of the double beams of the first beam 1 and the second beam 2, improving stability.

[0039] Reference Figure 2 and Figure 3 A weight-reducing groove is provided on one side of the second beam 2. The length direction of the weight-reducing groove is parallel to the length direction of the second beam 2. Multiple support plates 23 are fixedly connected to the groove wall. The support plates 23 are equidistantly distributed along the length direction of the second beam 2. The top wall of the support plate 23 is fixedly connected to the top wall of the weight-reducing groove, and the bottom wall of the support plate 23 is fixedly connected to the bottom wall of the weight-reducing groove. The two sides of the support plate 23 are respectively attached to the groove wall of the weight-reducing groove, thereby dividing the weight-reducing groove into multiple sub-grooves at equal intervals. The setting of the weight-reducing groove effectively reduces the weight of the second beam 2. At the same time, the design of multiple support plates 23 being equidistantly distributed along the length direction of the second beam 2 significantly improves the structural strength of the second beam 2. Thus, while ensuring the load-bearing capacity of the cantilever beam, the amount of material used is reduced, saving costs and achieving a balance between lightweight and high strength.

[0040] A first rod 24 is fixedly connected to the bottom wall of the weight-reducing trough. The length direction of the first rod 24 is parallel to the length direction of the second beam 2. The first rod 24 spans multiple support plates 23. In this example, the number of support plates 23 spanning the first rod 24 is four. A second rod 25 is provided parallel to the first rod 24. The side of the second rod 25 away from the first rod 24 is fixedly connected to the wall of the weight-reducing trough. A connector 251 is fixedly connected to the side of the first rod 24 near the second rod 25. The end of the connector 251 away from the first rod 24 is fixedly connected to the second rod 25. The connector 251 is horizontally arranged and has a trumpet-shaped frame shape with its opening facing the second rod 25. The connector 251 and the support plates 23 are distributed at intervals to strengthen the structural strength of the weight-reducing trough area and ensure that the cantilever beam is not easily deformed or broken when bearing large printing rollers, thereby significantly improving the safety and reliability of the equipment.

[0041] A third rod 26 is fixedly connected to the bottom wall of the weight-reducing trough. The third rod 26 is located at the bottom of the second rod 25. A reinforcing member 261 is fixedly connected to the side of the second rod 25 near the first rod 24. The end of the reinforcing member 261 away from the second rod 25 is fixedly connected to the third rod 26. The reinforcing member 261 is vertically set and is in the shape of a trumpet-shaped frame with its opening facing the third rod 26. The second rod 25 and the third rod 26 are connected by the reinforcing member 261, which further enhances the connection strength between the two, improves the stability of the overall structure, thereby reducing the possibility of structural damage caused by stress concentration and extending the service life of the cantilever beam.

[0042] A fourth rod 27 is fixedly connected to the bottom wall of the weight-reducing trough. The fourth rod 27 is located at the bottom of the first rod 24. A first fixed frame member 28 is fixedly connected to the side of the fourth rod 27 away from the trough wall. The end of the first fixed frame member 28 away from the fourth rod 27 is fixedly connected to the side of the first rod 24 near the second rod 25. A second fixed frame member 29 is fixedly connected to the side of the first rod 24 near the first fixed frame member 28. The end of the second fixed frame member 29 away from the first rod 24 is connected to the top wall of the weight-reducing trough. The first fixed frame member 28 and the second fixed frame member 29 abut against each other, thereby forming a rhomboid structure in the vertical plane, which enhances the structural connection of the first rod 24. The stability of the second rod 25 structure is further enhanced by the connector 251, thereby enhancing the structural stability of the second beam 2.

[0043] One side of the support plate 23 has a through-hole for the first rod 24, the second rod 25, the third rod 26 and the fourth rod 27 to pass through. One side of the support plate 23 has a through-hole 231. The stress hole 231 is located at the bottom of the support plate 23, which effectively releases local stress and reduces the possibility of structural damage caused by stress concentration, thereby significantly improving the stability and service life of the cantilever beam structure.

[0044] The first beam 1 has a weight-reducing cavity, and the structure inside the weight-reducing cavity is consistent with the internal structure of the weight-reducing groove in the second beam 2, which will not be described in detail here.

[0045] The implementation principle of the cantilever beam reinforcement structure for a large-scale printing roller storage and retrieval equipment according to an embodiment of this application is as follows: By paralleling the first beam 1 and the second beam 2 and symmetrically designing the frame 3, the load-bearing capacity and stability of the cantilever beam are significantly improved. The parallel arrangement of the first beam 1 and the second beam 2 ensures that the force generated by the hoisting mechanism during operation is evenly distributed on the two beams, reducing the possibility of deformation or breakage of the single beam structure due to concentrated force. The design of the weight-reducing groove and the support plate 23 reduces the weight of the cantilever beam, saves materials, and improves its structural strength. Furthermore, the first rod 24, the second rod 25, the third rod 26, and the fourth rod 27 are set up and connected by the connector 251 and the reinforcement 261, further enhancing the overall stability of the cantilever beam. This allows the cantilever beam structure to withstand greater loads, reduces structural damage caused by overload, and meets the high strength requirements of the large-scale printing roller storage and retrieval equipment.

[0046] The above are all preferred embodiments of this application. These embodiments are only explanations of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
