Description
Technical Field
[0001] This utility model relates to the field of crane technology, and in particular to an aluminum alloy guide rail crane. Background Technology
[0002] In modern industrial production and logistics, KBK guide rail cranes have been widely used due to their significant advantages, including light weight, convenient installation, stable operation, and corrosion resistance. Whether in machine manufacturing workshops, automobile assembly plants, warehouses, or logistics centers, KBK guide rail cranes undertake critical tasks such as material handling and equipment installation, playing a vital role in improving production efficiency and reducing labor intensity. With the continuous expansion of industrial production scale and the increasing demands for automation, higher standards are being placed on the performance and reliability of KBK guide rail cranes.
[0003] Existing aluminum alloy rail cranes typically consist of basic components such as a support frame, rails, and an electric hoist. Their working principle involves the electric hoist sliding on the rails, lifting and lowering goods via hooks to achieve material handling. The rails are generally fixed, and the electric hoist runs on the rails driven by a motor. The lifting position and speed are adjusted by controlling the motor's forward and reverse rotation and speed. The hook spacing is mostly fixed; adjustments often require additional tools for disassembly and reinstallation.
[0004] Existing aluminum alloy guide rail cranes experience significant impact forces when the electric hoist slides to the edge of the guide rail due to inertia or operational errors. These cranes lack effective cushioning structures to handle such impacts, leading to wear and damage to components like the electric hoist and guide rails, shortening equipment lifespan. Furthermore, they can cause goods to sway or even fall, posing significant safety hazards and impacting the safety and stability of production operations. Therefore, this paper proposes an aluminum alloy guide rail crane to address these issues. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] The buffer assembly includes a mounting plate and a damper. The side wall of the mounting plate is fixedly connected to the lower surface of the second slide rail. The side wall of the damper is fixedly connected to the side wall of the mounting plate. A buffer plate is fixedly connected to one end of the damper.

A rotating bar is rotatably connected to the side wall of the buffer plate. A slider is slidably connected inside the fixed plate. A spring is provided inside the fixed plate.

[0011] As a further description of the above technical solution:
[0012] One end of each of the rotating bars is rotatably connected to the side wall of the slider, one end of the spring is fixedly connected to the inside of the fixed plate, and the other end of the spring is fixedly connected to the side wall of the slider.
[0013] As a further description of the above technical solution:
[0014] The sliding block sidewall is slidably connected to the connecting plate sidewall, and the outer wall of the sliding block is fixedly connected to a fixing sleeve.
[0015] As a further description of the above technical solution:
[0016] A pull rod is slidably connected inside the fixed sleeve, and a locking block is fixedly connected to one end of the pull rod. The side wall of the locking block is slidably connected inside the fixed sleeve.
[0017] As a further description of the above technical solution:
[0018] The side wall of the connecting plate has multiple fixing holes, and the side wall of the card block passes through the sliding block and is slidably connected inside the fixing holes.
[0019] As a further description of the above technical solution:
[0020] A fixing ring is fixedly connected to the side wall of the pull rod, and the side wall of the fixing ring is slidably connected inside the fixing sleeve.
[0021] As a further description of the above technical solution:
[0022] A second spring is fitted on the side wall of the pull rod. One end of the second spring is fixedly connected inside the fixed sleeve, and the other end of the second spring is fixedly connected to the side wall of the fixed ring.
[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, when the electric hoist slides to the edge of the slide rail two, the buffer plate is first squeezed, pushing the rotating bar one to rotate. The rotating bar one drives the slider to slide inside the fixed plate. At the same time, the rotating bar two also rotates, assisting the slider to slide. During the sliding process, the slider will compress the spring one. The spring one will produce elastic deformation and store energy. At the same time, the damper consumes part of the impact energy through its own damping effect, thereby playing a role in buffering and shock absorption. This solves the problem that when the electric hoist slides to the edge of the slide rail on some aluminum alloy guide rail cranes, the inertia will generate a large impact force. Due to the lack of buffering, this will cause wear and damage to the electric hoist, guide rail and other components, shortening the service life of the equipment. The above structure improves the buffering effect of the equipment.
[0025] 2. In this utility model, by pulling the pull rod, the pull rod causes the locking block to exit from the fixing hole. At the same time, the fixing ring on the pull rod compresses the second spring. At this time, the sliding block can slide on the support rod. After moving it to the appropriate position, the pull rod is released, the second spring restores its elastic deformation, pushes the fixing ring and the pull rod, and causes the locking block to re-insert into the corresponding fixing hole, thereby fixing the position of the sliding block and completing the adjustment of the hook spacing. This adapts to goods of different sizes and ensures that the goods are lifted and transported smoothly. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] Reference Figures 1-3This utility model provides an embodiment of an aluminum alloy guide rail crane, including a support 1. A slide rail 2 is fixedly connected between the supports 1. The slide rail 2 provides a longitudinal moving track for a slide rail 3, enabling the slide rail 3 to move horizontally. The slide rail 3 is slidably connected inside the slide rail 2. The slide rail 3 provides a transverse moving track for an electric hoist 4. Together with the slide rail 2, the electric hoist 4 can move freely in two dimensions. The electric hoist 4 is slidably connected inside the slide rail 3, and it drives the lifting chain 5 to extend and retract, realizing… For lifting and hoisting goods, an electric hoist 4 has an internal rotating chain 5. The chain 5 connects the electric hoist 4 and the hook 6, transmitting the driving force of the electric hoist 4 to the hook 6 to suspend and lift the goods. The hook 6 is located on the lower surface of the chain 5, and a buffer assembly and an adjustment assembly are located on the lower surface of the slide rail 2 3. The buffer assembly includes a mounting plate 7 and a damper 8. The side wall of the mounting plate 7 is fixedly connected to the lower surface of the slide rail 2 3, and the mounting plate 7 is used to fix the damper 8, providing stable support for the damper 8. The side wall of the damper 8 is fixedly connected to the mounting plate 7. The side wall of mounting plate 7 is fitted with a damper 8 made of common shock-absorbing damping material. Its function is to dissipate the energy generated by the collision through its own damping characteristics, which is common knowledge and will not be elaborated further here. A buffer plate 9 is fixedly connected to one end of the damper 8. The buffer plate 9 is used to withstand the impact force when the electric hoist 4 collides, providing buffering and dispersing effects to prevent the impact force from concentrating on local components. A fixing plate 10 is fixedly connected to the lower surface of slide rail 2 3, providing a sliding track and support for the slider 13. A rotating bar 2 12 is rotatably connected to the side wall of mounting plate 7, providing buffering... Rotating bar 11 is rotatably connected to the side wall of plate 9. Rotating bar 11 and rotating bar 2 12 are used to transmit the impact force received by buffer plate 9 to slider 13. They cooperate with slider 13 to perform sliding motion, thereby achieving the effect of converting the impact force into the sliding kinetic energy of slider 13. Sliding slider 13 is slidably connected inside fixed plate 10. Spring 14 is set inside fixed plate 10. One end of rotating bar 11 and rotating bar 2 12 are rotatably connected to the side wall of slider 13. One end of spring 14 is fixedly connected to the inside of fixed plate 10, and the other end of spring 14 is fixedly connected to the side wall of slider 13.
[0036] Reference Figures 4-6The adjustment assembly includes a connecting plate 15, a support rod 17, and a sliding block 18. The upper surface of the connecting plate 15 is fixedly connected to the lower surface of the lifting chain 5. The connecting plate 15 is used to connect the lifting chain 5 and other components of the adjustment assembly. The side wall of the support rod 17 is fixedly connected to the inside of the connecting plate 15. The inner wall of the sliding block 18 is slidably connected to the side wall of the support rod 17. The upper surface of the hook 6 is fixedly connected to the lower surface of the sliding block 18. The sliding block 18 cooperates with the support rod 17 to slide, thereby moving the hook 6 and adjusting the distance between the hooks 6. The side wall of the sliding block 18 is slidably connected to the connecting plate 15. A fixing sleeve 19 is fixedly connected to the side wall of the connecting plate 15 and the outer wall of the sliding block 18. The fixing sleeve 19 is used to install components such as the pull rod 20 and the locking block 21. The pull rod 20 is slidably connected inside the fixing sleeve 19. The pull rod 20 is used to drive the locking block 21 to move, realizing the locking and unlocking operation of the sliding block 18. The state of the locking block 21 can be easily controlled by pulling the pull rod 20. The locking block 21 is fixedly connected to one end of the pull rod 20. The side wall of the locking block 21 is slidably connected inside the fixing sleeve 19. The locking block 21 is made of hard metal and its function is to be inserted into the fixing hole 16 of the connecting plate 15. To fix the position of the sliding block 18, the side wall of the connecting plate 15 has multiple fixing holes 16. The fixing holes 16 are used to cooperate with the locking block 21 to fix the sliding block 18 at different positions. The side wall of the locking block 21 passes through the sliding block 18 and is slidably connected inside the fixing holes 16, so that the locking block 21 can effectively restrict the movement of the sliding block 18 and ensure the stability after the hook 6 spacing is adjusted. The side wall of the pull rod 20 is fixedly connected to a fixing ring 22. The side wall of the fixing ring 22 is slidably connected inside the fixing sleeve 19. The fixing ring 22 is used to limit the sliding stroke of the pull rod 20 and also provides spring. Spring 23 provides a support point. Spring 23 is sleeved on the side wall of pull rod 20. One end of spring 23 is fixedly connected to the inside of fixed sleeve 19, and the other end of spring 23 is fixedly connected to the side wall of fixed ring 22. The function of spring 23 is to push fixed ring 22 and pull rod 20 to reset when pull rod 20 is not subjected to external force, so that the locking block 21 is automatically inserted into fixed hole 16. Pull rod 20, locking block 21, fixed ring 22 and spring 23 form an automatic locking structure, which achieves the effect of conveniently and quickly fixing the position of sliding block 18 and ensuring the stability of hook 6 after spacing adjustment.
[0037] Working Principle: When using this equipment, the electric hoist 4 is longitudinally moved via slide rail 2, and laterally moved via slide rail 3. When an object is hung on the hook 6, the chain 5 is raised and lowered by the electric hoist 4 to complete the lifting task. When the electric hoist 4 slides to the edge of slide rail 3, inertia will generate a large impact force. At this time, the buffer plate 9 is first compressed, and the buffer plate 9 pushes the rotating bar 11 to rotate. The rotating bar 11 drives the slider 13 to slide inside the fixed plate 10. At the same time, the rotating bar 2 12 will also rotate to assist the slider 13 in sliding. During the sliding process, the slider 13 will compress the spring 14. The spring 14 will undergo elastic deformation and store energy. At the same time, the damper 8 will play its damping role and consume energy. Part of the impact energy is effectively reduced by the synergistic effect of spring 14 and damper 8, thus mitigating the impact on the crane components and providing buffering and shock absorption, protecting the safe and stable operation of the equipment. When it is necessary to adjust the distance between the hooks 6, the operator pulls the lever 20. The lever 20 causes the locking block 21 to exit from the fixing hole 16 on the side wall of the connecting plate 15. During this process, the fixing ring 22 on the lever 20 compresses the spring 23. After the locking block 21 is completely out of the fixing hole 16, the sliding block 18 can slide on the support rod 17. After the operator moves the sliding block 18 to the appropriate position, the lever 20 is released. At this time, the spring 23 restores its elastic deformation, pushing the fixing ring 22 and the lever 20, causing the locking block 21 to re-insert into the corresponding fixing hole 16, thereby fixing the position of the sliding block 18 and completing the adjustment of the distance between the hooks 6.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
