Description

Technical Field

[0001] This utility model relates to the field of guide rail technology, and in particular to an arc-shaped guide rail structure. Background Technology

[0002] A guide rail is a mechanical component used to guide and constrain the movement of mechanical parts along a predetermined path, ensuring that moving parts, such as sliders, rollers, and worktables, can move smoothly, accurately, and with low friction. It is an indispensable basic component in modern mechanical systems.

[0003] Existing curved guide rails mostly use a single-track design, guiding the swing arm only through a sliding groove and roller. In this structure, the swing arm is prone to lateral swaying, tilting, or shaking during movement due to inertia, uneven load, or external disturbances. This not only leads to inaccurate motion trajectories but also accelerates wear on the rollers and track, affecting system stability and lifespan.

[0004] When a swing arm is subjected to asymmetrical loads, such as one side carrying a container while the other side is unloaded or subjected to external lateral impact, a significant torsional moment is generated. Due to the lack of reaction force on the opposite side, the swing arm is prone to torsional deformation, leading to structural damage or motion stagnation, and in severe cases, even derailment accidents. In addition, the connection between multiple swing arms is often relatively simple or uses an independent drive method, which results in a lack of forced linkage between the swing arms during movement, easily causing problems such as asynchronous movement, angle deviation, and inconsistent speed. In actual use, it is necessary to adjust its structure, increasing the process and reducing work efficiency. To address these issues, the inventors have proposed an arc-shaped guide rail structure to solve the aforementioned technical problems. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the aforementioned problems.

[0006] An arc-shaped guide rail structure includes a track, a connecting rod, a swing rod, a protective shell, and rollers. The track has an arc-shaped structure. The protective shell is sleeved on the outer side of the connecting rod and is coaxially arranged with the connecting rod. The surface of the protective shell is provided with several connecting blocks for assisting the connection of two adjacent swing rods. The connecting blocks have a raised structure and a connecting hole is opened in the middle of the connecting blocks. The surface of the swing rod is provided with several mounting holes. The rollers are located at the left and right ends of the swing rod. The surface of the track is provided with sliding grooves for matching the rollers. The track has a double track structure. The dual-track structure consists of two parallel sliding tracks arranged side by side on the same arc-shaped path. Each track has a sliding groove, and a roller is installed at each end of the swing rod, which moves within the sliding groove of the track. This structure improves upon the problem of the swing rod easily swaying or tilting to the left or right during movement in the single-track structure. Through the two-point constraint of the dual-track structure, the swing rod can run along the specified arc-shaped path, reducing lateral clearance and stabilizing its movement trajectory. When the swing rod is subjected to asymmetrical loads or external impacts, it will generate a torsional tendency. The dual-track structure can simultaneously provide reaction forces on both sides to form an anti-torsional moment and reduce the probability of structural torsional deformation. Furthermore, the series connection and linkage of the swing arms are achieved through interconnecting blocks, mechanically connecting multiple independent swing arms to form a motion chain that can move as a whole. When the drive mechanism drives the first swing arm to move, the force is transmitted to the next swing arm in sequence through the pin, realizing step-by-step linkage and completing continuous movement. At the same time, it ensures the synchronization of movement and the consistency of trajectory, eliminating movement deviation. The series connection ensures that the rotation angle and speed of each swing arm are related, avoiding the asynchrony, jamming or collision that may occur with independent drive.

[0007] Furthermore, the mounting hole and the connecting hole in the middle of the swing rod are coaxially arranged. When the mounting hole and the connecting hole are connected by a fastener, the fastener includes a bolt, a plug, a screw or other rod-shaped connecting object for fixing. The swing rod swings around the connecting hole as the center. The roller is connected to the mounting holes at the left and right ends of the swing rod through the wheel rod. When the mounting hole and the connecting hole are coaxial, the center point of the inserted fastener becomes the rotation center axis, and the swing rod rotates around this axis, reducing radial runout or eccentricity. This structure eliminates motion interference and avoids the additional shear force and friction at the connection point caused by off-axis connections, thus preventing problems such as jamming, wear, or even structural deformation. The coaxial design ensures that the force is transmitted along the axis and the movement is smooth, and it stabilizes the synchronization of multi-level linkage, making the movement angle and speed of the swing rod of each level match each other and avoiding cumulative errors.

[0008] Furthermore, one end of the track is equipped with a connecting block and screw holes for fixing the track installation position. The sliding groove extends to the surface of the connecting block. The track is hourglass-shaped, with a narrow middle section and wide ends, which makes the force flow smooth and easy. The wide areas at both ends bear the installation and connection loads and have high strength. The narrow middle section is a movement channel, which reduces the overall cost and motion inertia. The extension direction of the track is arc-shaped, and the screw holes penetrate the surface of the track. The connecting block, as a reinforcing structure, increases the strength and rigidity of the rail end. It is fixed to the equipment or frame using bolts or screws through the screw holes, ensuring that the entire guide rail system reduces loosening or deformation under load. The screw holes penetrate the rail surface, allowing operators to tighten the rail from above. This facilitates fine-tuning and alignment during installation, ensuring that the arc center of the rail matches the rotation center of the motion mechanism. The threaded connection method is easy to disassemble and assemble, facilitating on-site assembly, maintenance, or replacement of the equipment and reducing maintenance costs. The size and position of the screw holes can follow industry standards or actual usage conditions, enabling quick docking and interchangeability with other equipment.

[0009] Furthermore, the top of the connecting rod is provided with a bushing, one end of which is provided with a washer, and the end of the bushing away from the washer is provided with a locking block for placing a container waiting to be filled. The locking block has a hollow structure in the middle. The bushing and the washer provide rotational support for the connecting rod, playing a role in assisting in stabilizing the rotation center point. The bushing serves as the mounting position for a bearing or shaft, increasing the stability of the connecting rod rotating smoothly around the fixed axis. The washer is located at one end of the bushing and acts as an axial retaining ring, preventing the connecting rod from moving axially or detaching from the rotation axis during operation, ensuring stable system operation. The hollow locking block can hold the can, facilitating the filling process, such as filling of fluids or semi-liquid or semi-solid substances.

[0010] Furthermore, the connecting blocks have an alternating vertical structure and are respectively arranged on the surfaces of the left and right ends of the protective shell. When two adjacent connecting rods are connected, the connecting blocks are in contact with the surface of the swing rod in the vertical position, thereby reducing the probability of derailment and limiting the swing amplitude range of the swing rod, reducing the expansion of the stroke range caused by excessive swing angle. The structure employs a staggered series block design, increasing the contact area of ​​point connections to a surface constraint, forming a physical anti-derailment structure and establishing an anti-derailment lock. Under severe vibration or impact, the swing rod may experience axial movement or radial displacement. The staggered series blocks simultaneously adhere to the surface of the swing rod from the upper side and the lower side of the other side, forming a connection area for the swing rod, completely preventing it from detaching in the vertical direction. Furthermore, under conditions of equipment start-up and shutdown, collision, or high-frequency vibration, this structure can effectively absorb impact energy, preventing the connection points from loosening or being damaged due to repeated jumping.

[0011] Furthermore, a bottom sleeve is installed at the bottom of the protective shell to increase the center of gravity. When the protective shell moves along the protective shell, the force generated during the movement may increase the swing of the protective shell. The bottom sleeve increases the weight of the bottom of the protective shell. While increasing the center of gravity, the bottom sleeve also protects the bottom of the protective shell and reduces the wear generated when the bottom of the protective shell moves. Dynamic stability is improved by lowering the center of gravity of the structure and increasing the moment of inertia. When the guide rail starts or stops, the inertial force will cause a tendency to tilt forward or backward. The bottom sleeve increases the weight at the bottom, which lowers the center of gravity and enhances the self-stabilizing ability of the system. It can restore balance more quickly and reduce the amplitude and duration of swaying. Under periodic motion or external vibration, the increased weight at the bottom acts as dynamic damping, absorbing some vibration energy and making the movement quieter.

[0012] Furthermore, the track is designed for modular assembly, with the track having an arc-shaped J-shaped structure or being assembled into a runway structure. This design can decompose long or complex-shaped tracks into multiple standard units, achieving flexible on-site installation. Track segments can be freely combined on-site according to actual site requirements, without the need to customize the entire arc-shaped track, thereby shortening the installation cycle. In addition, when a section of track fails due to wear or damage, that section can be disassembled and replaced individually without replacing the entire track, resulting in low maintenance costs and short downtime.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. A double-track structure is adopted, with two parallel sliding tracks set side by side on the same arc path. Each track is equipped with a sliding groove. A roller is installed at each end of the swing rod and moves in the sliding groove of the track. This structure improves the problem that the swing rod is prone to swaying or tilting when moving in a single-track structure. 2. Through the two-point constraint of the double-track structure, the swing rod can run along the specified arc path, reducing lateral clearance and stabilizing its motion trajectory. When the swing rod is subjected to asymmetrical loads or external impacts, it will generate a torsional tendency. The double-track structure can provide reaction forces on both sides at the same time, forming anti-torsional torque and reducing the probability of structural torsion deformation. 3. The interconnected blocks realize the series connection and linkage of the swing arms, mechanically connecting multiple independent swing arms to form a motion chain that can move as a whole, eliminating motion deviation. The series connection ensures that the rotation angle and speed of each swing arm are related to each other, avoiding the asynchrony, jamming or collision that may occur from independent driving. 4. The interlocking blocks simultaneously adhere to the surface of the swing arm from the top of one side and the bottom of the other side, forming a connection area for the swing arm. This completely prevents it from detaching in the vertical direction. Furthermore, under conditions of equipment start-up and shutdown, collision, or high-frequency vibration, this structure can effectively absorb impact energy and prevent the connection point from loosening or being damaged due to repeated jumping.

Detailed Implementation

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0016] For this embodiment, please refer to Figures 1-10 The specific implementation of the arc-shaped guide rail structure includes a track 1, a connecting rod 2, a swing rod 3, a protective shell 4, and rollers 5. The track 1 has an arc-shaped structure. The protective shell 4 is sleeved on the outer side of the connecting rod 2 and is coaxial with the connecting rod 2. The surface of the protective shell 4 is provided with several connecting blocks 16 for assisting the connection of two adjacent swing rods 3. The connecting blocks 16 have a raised structure and a connecting hole 6 is opened in the middle of the connecting blocks 16. The surface of the swing rod 3 is provided with several mounting holes 7. The rollers 5 are located at the left and right ends of the swing rod 3. The surface of the track 1 is provided with sliding grooves 8 for matching the rollers 5. The track 1 is a double track structure. The dual-track structure consists of two parallel sliding tracks arranged side by side on the same arc-shaped path. Each track is equipped with a sliding groove 8. A roller 5 is installed at each end of the swing rod 3, which moves within the sliding groove 8 of the track. This structure improves upon the problem of the swing rod 3 easily swaying or tilting to the left or right when moving in a single-track structure. Through the two-point constraint of the dual-track structure, the swing rod 3 can run along the specified arc-shaped path, reducing lateral clearance and stabilizing its movement trajectory. When the swing rod 3 is subjected to asymmetrical loads or external impacts, it will generate a torsional tendency. The dual-track structure can simultaneously provide reaction forces on both sides to form an anti-torsional moment and reduce the probability of structural torsional deformation. Furthermore, the series connection and linkage of the swing rods 3 are achieved through the interconnecting blocks 16, which mechanically connect multiple independent swing rods 3 to form a motion chain that can move as a whole. When the drive mechanism drives the first swing rod 3 to move, the force will be transmitted to the next swing rod 3 in sequence through the pin, realizing step-by-step linkage and completing continuous movement. At the same time, it ensures the synchronization of movement and the consistency of trajectory, eliminates movement deviation, and ensures that the rotation angle and speed of each swing rod 3 are related to each other, avoiding the asynchrony, jamming or collision that may occur from independent drive.

[0017] The mounting hole 7 and the connecting hole 6 in the middle of the swing rod 3 are coaxially arranged. When the mounting hole 7 and the connecting hole 6 are connected by a fastener, the fastener includes a bolt, a plug, a screw or other rod-shaped connecting object used for fixing. The swing rod 3 swings around the connecting hole 6 as the center. The roller 5 is connected to the mounting holes 7 at both ends of the swing rod 3 through the wheel rod 9. When the mounting hole 7 and the connecting hole 6 are coaxial, the inserted fastener makes the center point of the fastener the rotation center axis, and the swing rod 3 rotates around this axis, reducing radial runout or eccentricity. This structure eliminates motion interference and avoids the additional shear force and friction at the connection point caused by the non-axial connection, which can lead to jamming, wear, or even structural deformation. The coaxial design ensures that the force is transmitted along the axis and the movement is smooth, and stabilizes the synchronization of multi-level linkage, so that the movement angle and speed of each swing rod are matched with each other, avoiding cumulative errors.

[0018] One end of the track 1 is equipped with a connecting block 10 and a screw hole 11 for fixing the installation position of the track 1. The sliding groove 8 extends to the surface of the connecting block 10. The track 1 is hourglass-shaped, with a narrow middle section and wide ends, which makes the force flow smooth and easy. The wide areas at both ends bear the installation and connection loads and have high strength. The narrow middle section is a movement channel, which reduces the overall cost and motion inertia. The extension direction of the track 1 is arc-shaped, and the screw hole 11 penetrates the surface of the track 1. The connecting block 10 serves as a reinforcing structure, increasing the strength and rigidity of the end of the rail 1. It is fixed to the equipment or frame using bolts or screws through the screw holes 11, ensuring that the entire guide rail system reduces loosening or deformation under load. The screw holes 11 penetrate the surface of the rail 1, allowing operators to tighten the rail 1 from above by inserting screws. This facilitates fine-tuning and alignment during installation, ensuring that the arc center of the rail 1 matches the rotation center of the motion mechanism. The threaded connection method is easy to disassemble and assemble, facilitating on-site assembly, maintenance, or replacement of the equipment and reducing maintenance costs. The size and position of the screw holes 11 can follow industrial standards or actual usage conditions, enabling quick docking and interchangeability with other equipment.

[0019] The top of the connecting rod 2 is provided with a bushing 12, one end of which is provided with a washer 13. The end of the bushing 12 away from the washer 13 is provided with a locking block 14 for placing a container waiting to be filled. The locking block 14 has a hollow structure in the middle. The bushing 12 and the washer 13 provide rotational support for the connecting rod 2 and play a role in stabilizing the rotation center point. The bushing 12 serves as the mounting position for a bearing or rotating shaft, increasing the stability of the connecting rod 2 rotating smoothly around a fixed axis. The washer 13 is located at one end of the bushing 12 and acts as an axial retaining ring to prevent the connecting rod 2 from moving axially or detaching from the rotating shaft during operation, ensuring stable system operation. The hollow locking block 14 can hold the container, facilitating the filling process, such as filling of fluids or semi-liquid or semi-solid substances.

[0020] The connecting blocks 16 have an alternating structure and are arranged on the left and right ends of the protective shell 4. When two adjacent connecting rods 2 are connected, the connecting blocks 16 are in contact with the surface of the swing rod 3 in the upper and lower positions, thereby reducing the probability of derailment and limiting the swing amplitude range of the swing rod 3, reducing the expansion of the stroke range caused by excessive swing angle. The structure employs a staggered series block 16 structure, which increases the contact area of ​​point connections to a surface constraint, forming a physical anti-derailment structure and establishing an anti-derailment lock. Under severe vibration or impact, the swing rod 3 may experience axial movement or radial displacement. The staggered series block 16 simultaneously adheres to the surface of the swing rod 3 from the upper side and the lower side of the other side, forming a connection area for the swing rod 3, which completely prevents it from detaching in the vertical direction. Furthermore, under equipment start-up, shutdown, collision, or high-frequency vibration conditions, this structure can effectively absorb impact energy and prevent the connection points from loosening or being damaged due to repeated jumping.

[0021] The bottom of the protective shell 4 is equipped with a bottom sleeve 15 for increasing the center of gravity. When the protective shell 4 moves along the protective shell 4, the force generated during the movement may increase the swing of the protective shell 4. The bottom sleeve 15 increases the weight of the bottom of the protective shell 4. While increasing the center of gravity, the bottom sleeve 15 also protects the bottom of the protective shell 4 and reduces the wear generated when the bottom of the protective shell 4 moves. Dynamic stability is improved by lowering the center of gravity of the structure and increasing the moment of inertia. When the guide rail starts or stops, the inertial force will cause a tendency to tilt forward or backward. The bottom sleeve 15 increases the weight at the bottom, which lowers the center of gravity and enhances the self-stabilizing ability of the system. It can restore balance more quickly and reduce the amplitude and duration of swaying. Under periodic motion or external vibration, the increased weight at the bottom plays a role in dynamic damping, absorbing some vibration energy and making the motion quieter.

[0022] The track 1 is a modular design, with an arc-shaped J-shaped structure or a track-like structure. This design can decompose long or complex-shaped tracks into multiple standard units, achieving flexible on-site installation. Track segments can be freely combined on-site according to actual site requirements, without the need to customize the entire arc-shaped track, thus shortening the installation cycle.
