A type of shelf rail

Abstract

This utility model discloses a shelving track, including two interlocking first and second track profiles. By setting the connection between the two track profiles as a beveled joint, with the front, upper side, and lower side of the track all beveled, the mating area between the two track profiles is increased, resulting in a more stable fit. The beveled design at the connection between the first and second upper bends allows the wheels to smoothly and continuously transition from one track segment to another, minimizing impact and vibration.

Description

Technical Field

[0001] This utility model relates to the field of warehousing, specifically to a shelf track. Background Technology

[0002] In racking systems, the tracks on the racks serve as the movement path for shuttles. Their flatness, straightness, and continuity are fundamental prerequisites for ensuring the smooth and efficient movement of the shuttles. Since racking tracks are usually laid out in sections of profiles, the processing technology for the connection ends between sections has become one of the key processes and core technical challenges of the entire track system.

[0003] Previous structures typically involved direct, untreated connections. In this type of structure, the track ends were not specially processed, leaving a gap between them. This method resulted in strong impacts, vibrations, and noise when the shuttle traveled to the joint, affecting not only the equipment's lifespan and operational stability, but also causing long-term impacts to loosen bolts at the joint and deform the track ends.

[0004] Another structural method is welding, where the ends of the rails are welded together to achieve continuity. While this solves the problem of discontinuity, the thermal stress generated by welding can alter the metallographic structure of the rail material, potentially leading to localized deformation. Furthermore, on-site welding precision is difficult to guarantee, making misalignment more likely. It also affects the adjustability and disassembly of the racking system.

[0005] Therefore, a new technical solution is needed to solve the above problems. Utility Model Content

[0006] Purpose of the utility model: In view of the above-mentioned shortcomings, this utility model provides a shelf track, which is used to stabilize the connection between track profiles, improve the overall flatness of the track, and facilitate disassembly.

[0007] Technical solution: To solve the above problems, the shelf track provided by this utility model can adopt the following technical solution:

[0008] A shelving track includes two interlocking first track profiles and second track profiles. The first track profile includes a first plate, a first track surface formed by bending from the upper edge of the first plate, a first upper bend formed by bending downward from the edge of the first track surface, a first bottom surface formed by bending from the lower edge of the first plate, and a first lower bend formed by bending upward from the edge of the first bottom surface. The interlocking end surfaces of the first plate protrude outward to form a pointed tip, both sides of which are straight edges. The end faces of the first upper bend and the first lower bend are both inclined inward. The leading edge of the surface of the first upper bend is a diagonal line.

[0009] The second track profile includes a second plate, a second track surface formed by bending from the upper edge of the second plate, a second upper bend formed by bending downward from the edge of the second track surface, a second bottom surface formed by bending from the lower edge of the second plate, and a second lower bend formed by bending upward from the edge of the second bottom surface; the mating end face of the second plate is recessed inward to form a triangular groove, both sides of which are straight edges; the end faces of the second upper bend and the second lower bend are both inclined outward; the leading edge of the surface of the second upper bend is a slant line and the inclination angle is complementary to the inclination angle of the leading edge of the surface of the first upper bend;

[0010] The end faces of the first track profile and the second track profile are abutted together. The mating end face of the first plate is abutted together with the mating end face of the second plate, and the edge of the pointed end is in contact with the edge of the groove. The end face of the first upper bend is in contact with the end face of the second upper bend. The end face of the first lower bend is in contact with the end face of the second lower bend. The leading edge of the surface of the first upper bend is in contact with the leading edge of the surface of the second upper bend.

[0011] Furthermore, the pointed end of the first plate has an axisymmetric structure, and the groove on the mating end of the second plate also has an axisymmetric structure.

[0012] Furthermore, the first upper bend and the first lower bend are axially symmetrical structures; the second upper bend and the second lower bend are also axially symmetrical structures.

[0013] Furthermore, the angle of the pointed tip is an obtuse angle, and the angle of the groove is the same as the angle of the pointed tip.

[0014] Furthermore, the angle between the extension line of the end face of the first upper bend and the extension line of the end face of the first lower bend is an obtuse angle; the angle between the extension line of the end face of the second upper bend and the extension line of the end face of the second lower bend is also an obtuse angle.

[0015] Beneficial effects: The shelving track provided by this utility model uses a beveled connection method between two track profiles, with beveled joints at the front, upper side, and lower side of the track. This results in a larger mating area between the two track profiles, leading to a more stable fit. The beveled design at the connection between the first and second upper bends allows the wheels to smoothly and continuously transition from one track segment to another, minimizing impact and vibration.

[0022] like Figures 1 to 6 As shown, this utility model discloses a shelf track, including two interlocking first track profiles 1 and second track profiles 2.

[0023] like Figure 3 and Figure 4 As shown, the first track profile 1 includes a first plate 3, a first track surface 4 formed by bending from the upper edge of the first plate 3, a first upper bend 5 formed by bending downward from the edge of the first track surface 4, a first bottom surface 6 formed by bending from the lower edge of the first plate 3, and a first lower bend 7 formed by bending upward from the edge of the first bottom surface 6. The mating end surface of the first plate 3 protrudes outward to form a pointed tip 8, both sides of which are straight edges; the end faces of the first upper bend 5 and the first lower bend 7 are both inclined inward.

[0024] like Figure 3 and Figure 5 As shown, the second track profile 2 includes a second plate 9, a second track surface 10 formed by bending from the upper edge of the second plate 9, a second upper bend 11 formed by bending downward from the edge of the second track surface 10, a second bottom surface 12 formed by bending from the lower edge of the second plate 9, and a second lower bend 13 formed by bending upward from the edge of the second bottom surface 12. The mating end of the second plate 9 is recessed inward to form a triangular groove 14, both sides of which are straight sides, and the angle and side length of the triangular groove 14 are consistent with those of the tip 8 of the first track profile. In this embodiment, openings are made at the tip of the tip 8 and the bottom corner of the groove 14, as well as at the intersection of the bending angles of the profile, to prevent these positions from being squeezed during the bending process, which would cause interference during the fit. This is also a common practice in the profile bending manufacturing process.

[0025] The end faces of the second upper bend 11 and the second lower bend 13 are both inclined outwards, and the angle of inclination is complementary to the angle of inclination of the end faces of the first upper bend 5 and the first lower bend 7. That is, combined with Figure 1 , Figure 2 As shown, after the end face of the first track profile 1 and the end face of the second track profile 2 are connected, the mating end face of the first plate 3 is connected to the mating end face of the second plate 9, and the edge of the tip 8 is attached to the edge of the groove 14; the end face of the first upper bend 5 is attached to the end face of the second upper bend 11; and the end face of the first lower bend 7 is attached to the end face of the second lower bend 13.

[0026] Combination Figure 6 As shown, the leading edge of the surface of the first upper bend 5 is a slanted line, and the leading edge of the surface of the second upper bend 11 is also a slanted line with an angle complementary to that of the leading edge of the surface of the first upper bend 5. After docking, the leading edges of the surfaces of the first upper bend 5 and the second upper bend 11 fit together. When the wheel 15 travels on the track, the slanted design at the connection between the first upper bend 5 and the second upper bend 11 allows the wheel to smoothly and continuously transition from one track segment to another, minimizing impact and vibration. Figure 6 The line where the first upper bend 5 and the second upper bend 11 fit together is indicated by the number 17, and the tangent line between the wheel and the track is indicated by the number 18. In this embodiment, the angle between the line 17 and the tangent line 18 is 15 degrees. This bevel disperses the concentrated impact force of the wheel on the track into a gentle force, thereby reducing wear and fatigue at the joint of the two track profiles.

[0027] In the above structure, the connection between the two track profiles is set as a beveled joint. The front, upper side, and lower side of the track are all beveled, resulting in a larger mating area and more stable fit between the two track profiles. In this embodiment, to ensure precise mating, the pointed end 8 of the first plate's mating end face is axially symmetrical, and the groove 14 of the second plate's mating end face is also axially symmetrical, with the pointed end 8 having an obtuse angle, and the groove 14 having the same angle as the pointed end. The first upper bend 5 and the first lower bend 7 are axially symmetrical; the second upper bend 11 and the second lower bend 13 are also axially symmetrical. The angle between the extension line of the end face of the first upper bend 5 and the extension line of the end face of the first lower bend 7 is an obtuse angle; the angle between the extension line of the end face of the second upper bend 11 and the extension line of the end face of the second lower bend 13 is an obtuse angle.

[0028] like Figure 1 and Figure 2 As shown, during installation, the first track profile 1 and the second track profile 2 are fixed to the upright 19 at their joint. The first track profile 1 and the second track profile 2 are respectively fixed to the upright 19 with bolts (not shown) near their joint position.
