Description

Technical Field

[0001] This utility model relates to the field of shelf guide rail technology, specifically a guide rail for a climbing robot shelf. Background Technology

[0002] The guide rails of climbing robot shelves are generally composed of upper and lower guide rail components. Considering the comprehensive analysis of the fact that the lower part of the climbing robot experiences greater impact force and the upper part experiences less force when climbing, the guide rail is divided into upper and lower parts. If a whole guide rail is used, a thickness of 2.5mm is required due to the greater impact force at the lower part, which increases material costs. However, by using segments, the upper guide rail can be 1.5mm thick, and the lower guide rail can be 1035mm long and 2.5mm thick, which not only saves processing and labor costs, but also reduces material costs.

[0003] However, when connecting the upper and lower guide rail assemblies, welding is usually used to connect the upper and lower guide rails. Due to the different thicknesses of the upper and lower guide rails, misalignment can easily occur during alignment welding, affecting the consistency and quality of the entire guide rail. Furthermore, the welded joints need to be ground smooth after welding. Since the upper and lower guide rail plates are thin, the weld joints are easily ground away, affecting their strength. Because the lower guide rail is subjected to greater impact force when the robot climbs, and friction during the robot's ascent and descent can easily cause the weld joints to crack or deform, resulting in insufficient guide rail strength. Therefore, there is an urgent need to design a guide rail for climbing robot shelves to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a guide rail for a climbing robot shelf, aiming to solve the problem that the upper and lower guide rails of existing climbing robot shelf guide rails have inconsistent thicknesses, which easily leads to misalignment during welding. After welding, grinding is required, which can easily result in insufficient guide rail strength.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A guide rail for a climbing robot shelf includes a lower guide rail and an upper guide rail. The cross-section of the lower guide rail and the upper guide rail is U-shaped. The ends of the lower guide rail and the upper guide rail that are close to each other are connected by a connecting component.

[0007] The lower guide rail includes a main body section and a connecting section. A transition section is provided between the connecting section and the main body section. The thickness of the connecting section is the same as the thickness of the upper guide rail, and the thickness of the main body section is greater than the thickness of the upper guide rail.

[0008] The lower guide rail and the upper guide rail are connected at equal intervals inside with several pitch blocks.

[0009] Preferably, the transition section is a sloping design on the outer side of the lower guide rail.

[0010] Preferably, the connecting assembly includes an inner connecting plate on the inner side of the connecting section between the upper guide rail and the lower guide rail, an outer connecting plate on the outer side of the connecting section between the upper guide rail and the lower guide rail, and bolt connectors. A third through hole is provided at the connection point on the connecting section between the upper guide rail and the lower guide rail. A first through hole is provided at each of the two corresponding third through holes on the inner connecting plate. A second through hole is provided at each of the two corresponding third through holes on the outer connecting plate. The corresponding first through holes, third through holes, and second through holes are coaxially arranged. The bolt connectors pass through the first through holes, third through holes, and second through holes to connect and fix the inner connecting plate and the outer connecting plate to the upper guide rail and the lower guide rail.

[0011] Preferably, the outer connecting plate is bent towards the inner connecting plate to form positioning blocks, the connecting section of the upper guide rail and the lower guide rail is provided with a first through groove for the positioning blocks to pass through, and the inner connecting plate is provided with positioning grooves to accommodate the positioning blocks.

[0012] Preferably, both sides of the lower guide rail and the upper guide rail are bent outward along the length direction to form flanges, and a positioning structure is provided between the flanges on the lower guide rail and the flanges on the upper guide rail.

[0013] Preferably, the positioning structure includes a positioning protrusion disposed on one end of the flange on the upper guide rail and a positioning groove formed on one end of the flange on the lower guide rail, wherein the positioning protrusion is aligned and inserted into the positioning groove.

[0014] Preferably, the widths of the positioning protrusion and the positioning groove gradually decrease along the direction from the upper guide rail to the lower guide rail.

[0015] Preferably, the pitch block includes a positioning body and fixing plates disposed on both sides of the positioning body. The fixing plates have a fourth through hole. Both sides of the fixing plates away from the positioning body are bent outward to form limiting blocks. The lower guide rail and the upper guide rail each have a second through groove for the limiting blocks to pass through. The lower guide rail and the upper guide rail each have a fifth through hole corresponding to the position of the fourth through hole. The pitch block is connected and fixed to the lower guide rail and the upper guide rail by rivets passing through the fourth through hole and the fifth through hole.

[0016] Preferably, both sides of the positioning body are bent inward to form side flanges, and reinforcing ribs are provided between the positioning body and the fixing plate. The pitch block is integrally stamped.

[0017] Preferably, the lower guide rail and the upper guide rail are provided with fixing holes at equal intervals, and a guide rail locking piece is fixedly welded to the bottom of the lower guide rail at the end away from the upper guide rail.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This invention features a lower guide rail composed of a main body section, a connecting section, and a transition section. The sloping design of the transition section on the lower guide rail results in a thicker main body section, enhancing its strength and enabling it to withstand the significant impact forces experienced by the robot during climbing. The connecting section of the lower guide rail has the same thickness as the upper guide rail, allowing it to be connected via a connecting assembly. This eliminates the need for welding and subsequent grinding of the weld joints, avoiding the problems of deformation or displacement that often occur during welding. By employing a segmented connection between the lower and upper guide rails, the guide rail of this climbing robot rack can be made relatively thinner, saving on processing and labor costs, reducing material costs, mitigating the risks associated with the robot's operation on the rack, and improving the mechanical and performance characteristics of the guide rail.

[0020] This utility model features a connecting assembly with inner and outer connecting plates positioned on the inner and outer sides of the connection section between the upper and lower guide rails, respectively. These plates are then connected and fixed to the upper and lower guide rails using bolts. The inner and outer connecting plates provide support on both sides of the connection point, improving the stability of the connection. Positioning blocks at both ends of the outer connecting plate pass through the first through-slot in the connection section between the upper and lower guide rails, positioning the outer connecting plate and enhancing its connectivity with the upper and lower guide rails. These positioning blocks then pass through the positioning slots of the inner connecting plate, further positioning both the inner and outer connecting plates. This improves the ease of assembly between the connecting assembly and the upper and lower guide rails, prevents misalignment of the connecting assembly, and ensures a reliable connection.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0034] Example: Please refer to Figures 1-11This embodiment provides a guide rail for a climbing robot shelf, including a lower guide rail 1 and an upper guide rail 2. The lower guide rail 1 and the upper guide rail 2 have a U-shaped cross-section. The lower guide rail 1 and the upper guide rail 2 are connected at their closest points via a connecting component 6. The lower guide rail 1 includes a main body section 101 and a connecting section 102. A transition section 103 is provided between the connecting section 102 and the main body section 101. The thickness of the connecting section 102 is the same as the thickness of the upper guide rail 2, while the thickness of the main body section 101 is greater than the thickness of the upper guide rail 2. The transition section 103 is a sloping design on the outer side of the lower guide rail 1. Several pitch blocks 9 are connected at equal intervals inside the lower guide rail 1 and the upper guide rail 2. Through the sloping design of the transition section 103 on the lower guide rail 1, the main body section of the lower guide rail 1... The thicker section 101 of the lower guide rail enhances its strength, enabling it to withstand the greater impact forces during robot climbing. The connecting section 102 of the lower guide rail 1 has the same thickness as the upper guide rail 2, allowing it to connect to the upper guide rail 2 via the connecting component 6. This eliminates the need for welding, which requires grinding the weld joint and avoids deformation or displacement issues during welding. By employing a segmented connection between the lower and upper guide rails 1 and 2, the upper guide rail 2 can be made relatively thinner than the lower guide rail 1, saving processing and labor costs, reducing material costs, mitigating the risks associated with robot operation on the shelf, and improving the mechanical and performance properties of the guide rail.

[0035] In this embodiment, as Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the connecting assembly 6 includes an inner connecting plate 601 on the inner side of the connecting section 102 between the upper guide rail 2 and the lower guide rail 1, an outer connecting plate 602 on the outer side of the connecting section 102 between the upper guide rail 2 and the lower guide rail 1, and a bolt connector 603. A third through hole 8 is provided at the connection point on the connecting section 102 between the upper guide rail 2 and the lower guide rail 1. A first through hole 6012 is provided on the inner connecting plate 601 at each of the two third through holes 8. A second through hole 6022 is provided on the outer connecting plate 602 at each of the two third through holes 8. The corresponding first through holes 6012, third through holes 8, and second through holes 6022 are coaxially arranged. The bolt connector 603 passes through the first through holes 6012, third through holes 8, and second through holes 6022 to connect the inner... The connecting plate 601 and the outer connecting plate 602 are connected and fixed to the upper guide rail 2 and the lower guide rail 1. The inner connecting plate 601 and the outer connecting plate 602 are respectively placed on the inner and outer sides of the connecting section 102 between the upper guide rail 2 and the lower guide rail 1. The inner connecting plate 601 and the outer connecting plate 602 are then connected and fixed to the upper guide rail 2 and the lower guide rail 1 by bolt connectors 603. The inner connecting plate 601 and the outer connecting plate 602 can provide support on the inner and outer sides of the connection between the upper guide rail 2 and the lower guide rail 1, improving the connection stability. Compared with the existing technology that uses welding to connect the upper guide rail 2 and the lower guide rail 1, this method can ensure a smooth transition at the connection, eliminating the need for grinding after welding, reducing the difficulty of processing and assembly, and saving processing and labor costs.

[0036] In this embodiment, as Figure 4 , Figure 5 and Figure 6 As shown, the outer connecting plate 602 is bent towards the inner connecting plate 601 on all four sides to form positioning folding blocks 6021. The positioning folding blocks 6021 and the outer connecting plate 602 are integrally stamped. The connecting section 102 of the upper guide rail 2 and the lower guide rail 1 is provided with a first through groove 7 for the positioning folding blocks 6021 to pass through. The inner connecting plate 601 is provided with positioning grooves 6011 on all four sides to accommodate the positioning folding blocks 6021. When the outer connecting plate 602 is assembled with the upper guide rail 2 and the lower guide rail 1, the positioning folding blocks 6021 on both ends of the outer connecting plate 602 are respectively bent from the inner connecting plate 601 to the inner connecting plate 602. The first through groove 7 on the connecting section 102 of the upper guide rail 2 and the lower guide rail 1 passes through to position the installation position of the outer connecting plate 602 and improve the connection between the outer connecting plate 602 and the upper guide rail 2 and the lower guide rail 1. Then, the positioning folding blocks 6021 on both ends of the outer connecting plate 602 pass through the positioning groove 6011 of the inner connecting plate 601 to position the installation position of the inner connecting plate 601 and the outer connecting plate 602, improve the ease of assembly of the connecting component 6 with the upper guide rail 2 and the lower guide rail 1, avoid the installation position of the connecting component 6 from being offset, and ensure the connection effect.

[0037] In this embodiment, as Figure 3 and Figure 4As shown, both the lower guide rail 1 and the upper guide rail 2 are bent outwards along their length to form flanges 3. A positioning structure is provided between the flanges 3 on the lower guide rail 1 and the flanges 3 on the upper guide rail 2. The positioning structure includes a positioning protrusion 4 at one end of the flange 3 on the upper guide rail 2 and a positioning groove 5 at one end of the flange 3 on the lower guide rail 1. The positioning protrusion 4 is aligned and inserted into the positioning groove 5. When the lower guide rail 1 and the upper guide rail 2 are assembled, the positioning protrusion 4 is aligned and inserted into the positioning groove 5 to achieve the desired effect. Positioning is performed during the assembly of the lower guide rail 1 and the upper guide rail 2 to avoid misalignment of their assembly positions, thereby improving the accuracy of their alignment. Furthermore, the widths of the positioning protrusion 4 and the positioning groove 5 gradually decrease along the direction from the upper guide rail 2 to the lower guide rail 1, ensuring that the narrower end of the positioning protrusion 4 enters the wider end of the positioning groove 5 first during assembly. This guides alignment, reduces the difficulty of alignment, and improves assembly efficiency.

[0038] In this embodiment, as Figure 8 , Figure 9 and Figure 10 As shown, the pitch block 9 includes a positioning body 901 and fixing plates 902 disposed on both sides of the positioning body 901. The fixing plates 902 have a fourth through hole 904. Both sides of the fixing plate 902 away from the positioning body 901 are bent outwards to form limiting blocks 903. The lower guide rail 1 and the upper guide rail 2 each have a second through groove 10 for the limiting blocks 903 to pass through. The lower guide rail 1 and the upper guide rail 2 each have a fifth through hole 11 corresponding to the position of the fourth through hole 904. The pitch block 9 is secured by rivets. The pitch block 9 is connected and fixed to the lower guide rail 1 and the upper guide rail 2 through the fourth through hole 904 and the fifth through hole 11. The pitch block 9 is initially inserted and fixed to the second through groove 10 on the lower guide rail 1 and the upper guide rail 2 through four limiting folding blocks 903, and then fixed by rivets to provide stability of the connection and fixation. The positioning body 901 is bent inward on both sides to form a side flange. A reinforcing rib is provided between the positioning body 901 and the fixing plate 902. The pitch block 9 is integrally stamped to enhance the structural strength of the pitch block 9.

[0039] In this embodiment, as Figure 11 As shown, fixing holes 12 are equally spaced on the lower guide rail 1 and the upper guide rail 2. A guide rail locking piece 13 is fixedly welded to the bottom of the lower guide rail 1 at the end away from the upper guide rail 2. First, the guide rail locking piece 13 is installed and fixed to the lower end of the shelf with fixing bolts for precise installation. Then, the overall guide rail composed of the lower guide rail 1 and the upper guide rail 2 is installed and fixed on the shelf by fixing bolts passing through the fixing holes 12, thus completing the installation of the guide rail.

[0040] Working principle: During use, the connecting section 102 of the lower guide rail 1 is aligned and assembled with the upper guide rail 2. By aligning and inserting the positioning protrusion 4 at one end of the flange 3 on the upper guide rail 2 into the positioning groove 5 at one end of the flange 3 on the lower guide rail 1, the lower guide rail 1 and the upper guide rail 2 can be positioned during assembly, preventing misalignment of the assembly positions. Then, the inner connecting plate 601 is placed outside the connection between the upper guide rail 2 and the lower guide rail 1. The positioning folds 6021 on both ends of the outer connecting plate 602 pass through the first through groove 7 on the connecting section 102 of the upper guide rail 2 and the lower guide rail 1, respectively, to position the installation position of the outer connecting plate 602. The inner connecting plate 601 is then placed at the connection between the upper guide rail 2 and the lower guide rail 1. Inside the outer connecting plate 602, positioning folding blocks 6021 on both ends of the outer connecting plate 602 pass through the positioning grooves 6011 of the inner connecting plate 601 to position the installation positions of the inner connecting plate 601 and the outer connecting plate 602. Then, bolts 603 pass through the first through hole 6012, the third through hole 8, and the second through hole 6022 to connect and fix the inner connecting plate 601 and the outer connecting plate 602 to the upper guide rail 2 and the lower guide rail 1. The inner connecting plate 601 and the outer connecting plate 602 provide support on both the inner and outer sides of the connection between the upper guide rail 2 and the lower guide rail 1, improving the connection stability. When the pitch block 9 is installed on the lower guide rail 1 and the upper guide rail 2, the pitch block 9 is connected to the second through hole 6011 on the lower guide rail 1 and the upper guide rail 2 by four limiting folding blocks 903. The through slot 10 is initially inserted and fixed, and then connected and fixed with rivets to provide a stable connection. The positioning body 901 is bent inward on both sides to form a side flange. Reinforcing ribs are provided between the positioning body 901 and the fixing plate 902. The pitch block 9 is integrally stamped to enhance the structural strength of the pitch block 9. Then, the guide rail locking piece 13 is installed and fixed to the lower end of the shelf with fixing bolts for precise installation. Then, the integral guide rail composed of the lower guide rail 1 and the upper guide rail 2 is installed and fixed to the shelf with fixing bolts through the fixing holes 12 to complete the installation of the guide rail. The guide rail of this climbing robot shelf has a sloping design on the upper transition section 103 of the lower guide rail 1, which makes the main body section 101 of the lower guide rail 1... The greater thickness of the lower guide rail 1 increases its strength, enabling it to withstand the greater impact force during robot climbing. The connecting section 102 of the lower guide rail 1 has the same thickness as the upper guide rail 2, allowing it to be connected to the upper guide rail 2 via the connecting component 6. This eliminates the need for welding as in existing technologies, which requires grinding the weld joint and avoids the problems of deformation or displacement during welding. By employing a segmented connection between the lower guide rail 1 and the upper guide rail 2, the upper guide rail 2 can be made relatively thinner than the lower guide rail 1, saving processing and labor costs, reducing material costs, avoiding the risks associated with the robot running on the shelf, and improving the mechanical and performance properties of the guide rail.

[0041] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
