Description

Technical Field

[0001] This invention relates to the field of logistics sorting technology, and in particular to a frame component and a narrow-strip linear sorting machine using the component. Background Technology

[0002] In the field of logistics sorting, narrow-belt linear sorters are core equipment for efficient goods sorting. Their circular conveyor components consist of multiple sequentially connected trolleys. The stable operation of these trolleys directly determines the overall working efficiency and sorting accuracy of the sorting machine. The trolley mounting base, as the mounting carrier for the key components of the trolleys, plays a crucial role in the performance of the trolleys due to its structural rationality and reliability. To improve the problems of inconvenient assembly and difficulty in controlling component installation errors in traditional trolley installation processes, existing technologies have set a special reference surface on the crossbeam of the trolley mounting base. This reference surface provides the installation positioning basis for core components such as the sliding contact head seat and secondary plate. With the positioning function of the reference surface, not only is the component installation process simplified and the assembly difficulty reduced, but the positional accuracy of each component can also be guaranteed in the initial installation stage, thereby meeting the basic assembly and operation requirements of the trolley. However, in actual long-term use, sorting machines typically operate under high frequency and high load conditions. As the trolley moves along the circular track, it continuously rubs against the track and experiences impact forces. Simultaneously, the vibrations generated by the overall operation of the sorting machine are gradually transmitted through the frame to the trolley mounting base. Currently, most fasteners used to fix components such as the sliding contact head and secondary plate to the reference surface rely solely on conventional threaded connections, lacking anti-loosening structures designed to address the continuous vibrations and external forces during operation. Under the combined effects of long-term vibration and continuous external forces, the fasteners on the reference surface gradually loosen. Initially, this may only manifest as an increased clearance between the fastener and the threaded hole. As usage time increases, the loosening intensifies, leading to a continuous decrease in the fastener's preload. Components initially precisely positioned by the reference surface gradually deviate from their intended installation positions, rendering the reference surface's positioning function ineffective and ultimately causing overall assembly inaccuracies in the trolley mounting base. This misalignment problem will directly have a negative impact on the normal operation of the vehicle. For example, the position of the sliding contact seat will be offset, which will reduce the stability of its contact with the power supply structure, making it easy for power supply to be interrupted or for poor contact to occur, thus affecting the normal operation of the vehicle's drive system.

[0003] In view of this, a frame component and a narrow-strip linear sorting machine using the component are proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a frame component and a narrow-strip linear sorting machine using the component, which can delay the misalignment time of the reference plane.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: A frame component includes a crossbeam with a reference plate integrally formed with the crossbeam. The reference plate has a reference surface for mounting a sliding contact. The reference plate has a first fixing through hole and a second fixing through hole. A boss is provided between the first fixing through hole and the second fixing through hole, and the boss is located at the center point of the line connecting the first fixing through hole and the second fixing through hole.

[0006] In a preferred embodiment, the height of the boss is set to 0.5-1mm.

[0007] In a preferred embodiment, the boss is configured as circular or rectangular.

[0008] In a preferred embodiment, the reference plate is hollow inside, and a liquid flow channel is provided on the side, with a sealing cap on the liquid flow channel.

[0009] In a preferred embodiment, the liquid flow pipeline includes a first pipeline and a second pipeline. The first pipeline and the second pipeline are provided with annular steps and filter screens. The edges of the steps are provided with arc-shaped grooves. An adjustment cavity is formed between the filter screen and the annular steps. A sealing ball is provided in the adjustment cavity. The shape of the sealing ball is adapted to the shape of the arc-shaped groove.

[0010] In a preferred embodiment, the aperture of the filter screen in the first pipe is larger than the aperture of the filter screen in the second pipe.

[0011] In a preferred embodiment, the aperture of the filter screen in the first pipe is set to 1-3 mm, and the space of the filter screen in the second pipe is set to 0.3-0.5 mm.

[0012] In a preferred embodiment, the diameter of the sealing ball is set to 4-5 mm.

[0013] A narrow-strip linear sorting machine includes the aforementioned frame components.

[0014] Compared with existing technologies, the crossbeam of this invention, as the core load-bearing foundation, is manufactured integrally with the reference plate using a molding process. This not only ensures the structural strength of the connection between the two and avoids initial errors caused by assembly gaps, but also provides a stable reference carrier for the installation of the sliding contact. The first and second fixing through holes on the reference plate provide accurate assembly positions for bolting the sliding contact mounting plate. The boss located at the center point of the line connecting the two through holes will form a tight abutment with the corresponding position on the sliding contact mounting plate during the installation of the sliding contact. When the bolt passes through the first and second fixing through holes and locks with the sliding contact mounting plate, the locking force of the bolt will cause the sliding contact mounting plate to generate a pressing force towards the reference plate, while the abutment of the boss against the mounting plate will form a reverse supporting force. These two forces counterbalance each other, so that the fixed state of the sliding contact mounting plate on the reference surface forms a stable mechanical equilibrium. This mechanically balanced structure effectively disperses vibrations and external forces generated during equipment operation. On one hand, when the frame components vibrate during sorting machine operation, the boss's supporting action prevents the sliding contact mounting plate from undergoing minor displacement due to vibration, thus preventing thread wear and preload reduction caused by continuous relative shaking between the bolts and threaded holes. On the other hand, facing the lateral forces or loads transmitted by the crossbeams that the sliding contact may experience during operation, the synergistic fixing effect formed by the boss and bolt locking force evenly distributes the external force across the entire reference plate, rather than concentrating it at the bolt connection point. This reduces the stress borne by the bolts alone, thereby delaying or even preventing loosening of the bolts due to long-term stress concentration. This design breaks through the limitations of traditional methods that rely solely on bolt fixing. Through the mechanical synergy of the boss and bolts, it significantly improves the fixing stability of the sliding contact on the reference surface, effectively extending the time before the reference surface becomes inaccurate due to bolt loosening. This ensures that the sliding contact maintains a precise installation position for a long time, reducing equipment failures caused by reference surface inaccuracy, lowering maintenance frequency and costs, and providing a reliable guarantee for the long-term stable operation of the frame components and the entire sorting equipment.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention. Example

[0024] like Figures 1 to 5 As shown, a frame component includes a crossbeam 1, a reference plate 2 is provided on the crossbeam 1, the reference plate 2 is integrally formed with the crossbeam 1, the reference plate 2 is provided with a reference surface 3 for installing a sliding contact, the reference plate 2 is provided with a first fixing through hole 6 and a second fixing through hole 5, a boss 6 is provided between the first fixing through hole 6 and the second fixing through hole 5, the boss 6 is located at the center point of the line connecting the first fixing through hole 6 and the second fixing through hole 5.

[0025] The crossbeam 1 of this invention serves as the core load-bearing foundation and is manufactured integrally with the reference plate 2 using a molding process. This not only ensures the structural strength of the connection between the two and avoids initial errors caused by assembly gaps, but also provides a stable reference carrier for the installation of the sliding contact. The first fixing through hole 6 and the second fixing through hole 5 on the reference plate 2 provide accurate assembly positions for bolting the sliding contact mounting plate. The boss 6, located at the center point of the line connecting the two through holes, will form a tight abutment with the corresponding position of the sliding contact mounting plate during the installation of the sliding contact. When the bolt passes through the first fixing through hole 6 and the second fixing through hole 5 and locks with the sliding contact mounting plate, the locking force of the bolt will cause the sliding contact mounting plate to generate a pressing force towards the reference plate 2, while the abutment of the boss 6 against the mounting plate will form a reverse supporting force. These two forces counterbalance each other, so that the fixed state of the sliding contact mounting plate on the reference surface 3 forms a stable mechanical equilibrium. This mechanical balance structure can effectively disperse the vibration and external force generated during the operation of the equipment: on the one hand, when the frame components are vibrated as the sorting machine runs, the supporting action of the boss 6 can prevent the sliding contact mounting plate from being slightly displaced due to vibration, thereby preventing thread wear and preload reduction caused by continuous relative shaking between the bolt and the threaded hole; on the other hand, facing the lateral force that the sliding contact may be subjected to or the load force transmitted by the crossbeam 1, the synergistic fixing action formed by the boss 6 and the bolt locking force can evenly distribute the external force to the entire reference plate 2, rather than concentrating it at the bolt connection point, reducing the stress borne by the bolt alone, thereby delaying or even preventing the loosening of the bolt due to long-term stress concentration. This design breaks through the limitations of traditional methods that rely solely on bolts for fixation. Through the mechanical synergy between the boss 6 and the bolts, it significantly improves the fixation stability of the sliding contact on the reference surface 3, effectively extending the time that the reference surface 3 becomes inaccurate due to bolt loosening. This ensures that the sliding contact maintains a precise installation position for a long time, reduces equipment failures caused by inaccuracy of the reference surface 3, lowers maintenance frequency and costs, and also provides a reliable guarantee for the long-term stable operation of the frame components and even the entire sorting equipment.

[0026] Furthermore, the height of the boss 6 is set to 0.5-1mm. Setting the height of the boss 6 to 0.5-1mm ensures that the boss 6 and the sliding contact mounting plate form an effective abutment, providing sufficient reverse support force to counteract the bolt tightening force and avoid failure of the abutment due to insufficient height, thus preventing loosening. It also prevents the mounting plate from deforming due to excessive height of the boss 6, or causing the mounting plate to not fit tightly with the reference surface 3. This balances the anti-loosening effect and the installation fit, ensuring the long-term accuracy of the reference surface 3.

[0027] Furthermore, the boss 6 is configured as either circular or rectangular. Configuring the boss 6 as either circular or rectangular allows it to meet the contact requirements of the sliding contact mounting plate: a circular boss 6 can evenly distribute the resisting force across the contact area, avoiding localized stress concentration that could lead to wear on the mounting plate; a rectangular boss 6, on the other hand, can improve support stability through a larger contact area, especially suitable for scenarios with flat contact surfaces on the mounting plate.

[0028] Furthermore, the reference plate 2 is hollow inside, and a liquid flow pipe is provided on the side, with a sealing cap on the liquid flow pipe. The reference plate 2 features an internal hollow design and a liquid flow channel with a sealing cap on its side. Incompressible liquids such as water can be filled into the hollow cavity through this channel. Utilizing the incompressible nature of the liquid, it provides stable support to the internal structure of the reference plate 2, effectively resisting the deformation tendency of the reference surface 3 under external forces during equipment operation. This ensures that the reference surface 3 maintains a precise planar shape over the long term, avoiding positioning inaccuracies caused by structural deformation. Simultaneously, the hollow structure itself endows the reference plate 2 with a certain degree of micro-deformation capability. When the equipment is subjected to external forces such as impact or vibration, the reference plate 2 can buffer the external force through slight deformation, reducing the direct transmission of external force to the reference surface 3 and fixed components, and lowering the risk of component loosening. Furthermore, the liquid within the cavity absorbs heat during equipment operation and disperses it through liquid flow, playing a good temperature regulation role. This prevents uneven thermal expansion and contraction of the reference plate 2 due to excessively high local temperatures, further ensuring the structural stability and positioning accuracy of the reference surface 3. The sealing cap ensures that the liquid within the cavity does not leak, maintaining the long-term stability of the liquid's support, buffering, and temperature control effects.

[0029] Furthermore, the liquid flow pipeline includes a first pipeline 7 and a second pipeline 8. The first pipeline 7 and the second pipeline 8 are provided with annular steps 9 and filter screens 11. The edge of the steps is provided with arc-shaped grooves 10. An adjustment cavity is formed between the filter screens 11 and the annular steps 9. A sealing ball 12 is provided in the adjustment cavity. The shape of the sealing ball 12 is adapted to the shape of the arc-shaped groove 10. During assembly, the external infusion mechanism is connected to two pipes, allowing for flexible selection of one for inlet and the other for outlet. This enables efficient circulation of air removal and liquid filling within the cavity, ensuring thorough filling without residual air bubbles. Before filling, the sealing ball 12 is pushed off the arc-shaped groove 10 by the push rod provided with the infusion mechanism, releasing the blockage on the pipe and allowing the liquid to flow smoothly into the reference plate 2. After filling, the external infusion mechanism is removed and the push force is withdrawn. The sealing ball 12 will reset under the pressure of the liquid within the cavity, re-fitting tightly against the arc-shaped groove 10, achieving automatic sealing of the pipe and effectively preventing liquid leakage. Simultaneously, the filter screen 11 intercepts impurities that may be present in the external liquid, preventing them from entering the hollow cavity of the reference plate 2 and causing blockage or affecting liquid flow. This ensures the long-term stability of the subsequent liquid's support, buffering, and temperature control effects on the reference surface 3, further enhancing the practicality and reliability of the overall structure of the reference plate 2.

[0030] Furthermore, the pore size of the filter screen 11 in the first pipe 7 is larger than that of the filter screen 11 in the second pipe 8. By setting the pore size of the filter screen 11 in the first pipe 7 to be larger than that in the second pipe 8, and by incorporating magnetic powder of a specific particle size (between the pore sizes of the two pipes) during liquid filling, a precise magnetic powder retention and magnetization scheme for the reference plate 2 is formed. During liquid filling, the liquid carrying the magnetic powder flows into the first pipe 7. Because the particle size of the magnetic powder is smaller than that of the filter screen in the first pipe 7, it can smoothly enter the hollow cavity of the reference plate 2. When the liquid flows out from the second pipe 8, the magnetic powder, because its particle size is larger than that of the filter screen in the second pipe 8, is intercepted within the cavity and ultimately evenly distributed inside the reference plate 2, resulting in uniform magnetism in the reference plate 2. This uniform magnetism generates a stable and comprehensive attraction force on the sliding contact mounting plate. On the one hand, it can accurately attract and position the mounting plate on the reference surface 3, avoiding deviation during installation and ensuring the accuracy of its initial position. On the other hand, the mounting plate, after being attracted and fixed, can maintain a stable posture without additional manual support, greatly facilitating the operation of passing the bolts through the fixing through hole. It can also guide the two bolts to accurately align with the mounting hole, reducing the positional deviation of the bolts during installation. This makes the fixing position more accurate and the force more balanced when the bolts are tightened later, further enhancing the stability of the sliding contact installation. From both the installation operation and structural stress aspects, it ensures the long-term reliability of the positioning accuracy of the reference surface 3, avoiding the problem of inaccuracy of the reference surface 3 caused by installation deviation or uneven bolt force.

[0031] After assembly, the connection method and liquid flow direction of the external infusion mechanism can be adjusted to reverse the liquid flow and discharge the magnetic powder inside the reference plate 2. At this time, the original liquid outlet second pipe 8 is used as the liquid inlet and the original liquid inlet first pipe 7 is used as the liquid outlet. The liquid delivered by the external infusion mechanism flows into the hollow cavity of the reference plate 2 from the second pipe 8. Because the magnetic powder particle size is smaller than the filter hole diameter of the first pipe 7 and larger than the filter hole diameter of the second pipe 8, the thrust generated by the liquid flow will drive the magnetic powder in the cavity to move towards the first pipe 7. Finally, the magnetic powder flows out of the reference plate 2 from the first pipe 7 along with the liquid and completely leaves the cavity.

[0032] In this embodiment, the aperture of the filter screen 11 in the first pipe 7 is set to 1-3 mm, the space of the filter screen 11 in the second pipe 8 is set to 0.3-0.5 mm, and the diameter of the sealing ball 12 is set to 4-5 mm. Example
