Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically to a two-way anti-sway lifting device. Background Technology

[0002] Lifting equipment is an electromechanical device used for vertical lifting or vertical lifting and horizontal movement of heavy objects. It is widely used in industries, construction, logistics and other fields. Its working process usually includes cyclical actions of picking up, moving, unloading and returning to the original position, and the operation of each mechanism is intermittent.

[0003] The overload protection structure in existing equipment can only protect against overload when gripping. If the load is too heavy, it cannot provide overload protection. Furthermore, if there is excessive shaking during the transfer of goods, the centrifugal force generated by the shaking can also cause overload problems, posing a significant safety hazard.

[0004] To overcome the aforementioned deficiencies, existing technology (Chinese Patent No. CN119038415B, Publication Date: 2025-02-25) discloses a gantry crane with anti-sway design, specifically addressing the problem of inadequate overload protection in existing technologies. The gantry crane includes a transfer beam gantry with a sliding groove on its upper sliding surface. A displacement slide block is fitted within the sliding groove, and a hoist for lifting is mounted on the displacement slide block. A lifting rope is wound around the output end of the hoist, and a grab bucket assembly for gripping cargo is located at the lower end of the rope. The grab bucket assembly includes an anti-sway energy-absorbing rod connected to the lower end of the rope. This anti-sway gantry crane is designed to meet existing needs, quickly cutting off power when obstruction occurs during cargo grabbing, preventing overload of the motor and components, and rapidly eliminating cargo swaying. Furthermore, it can limit the equipment's operation when overloaded, ensuring operational safety.

[0005] While the above design can solve the aforementioned problems, the lifting process often relies solely on linear devices such as steel cables to hoist the items. This design causes the items to swing significantly during the ascent, and excessive swing can even affect the overall stability of the equipment's bottom. Furthermore, the retraction and ascent of the steel cables within the equipment relies almost entirely on traction, lacking the auxiliary function of horizontal retraction, resulting in insufficient practicality and stability of the equipment. Utility Model Content

[0006] The purpose of this utility model is to provide a two-way anti-sway lifting device to solve the problems mentioned in the background art, where the lifting operation of the device often relies solely on linear devices such as steel cables to suspend the object. This design causes the object to swing significantly during the ascent, and the excessive swing amplitude can even affect the overall stability of the bottom of the device. At the same time, during the retraction and ascent of the steel cable inside the device, it mainly relies on traction to move upward and cannot perform the auxiliary function of horizontal retraction, resulting in insufficient practicality and stability of the device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a bidirectional anti-sway lifting device, comprising a bottom support plate, a vertical sliding frame installed on the upper surface of the bottom support plate, a retraction stabilizing mechanism for limiting the vertical movement of an extension frame installed inside the vertical sliding frame, the retraction stabilizing mechanism comprising the vertical sliding frame, and a first rotating rod installed on the upper surface of the bottom support plate, horizontal sliding inner grooves provided on the left and right sides of the extension frame limiting, and a fitting auxiliary mechanism for supporting the lifting hook component installed inside the horizontal sliding inner grooves.

[0008] Furthermore, the fitting auxiliary mechanism includes a supporting movable disc, and the left and right sides of the supporting movable disc are slidably installed inside the horizontal sliding inner groove. A retractable reset frame is installed inside the extension frame limiter, and the end of the lifting hook is fixedly installed on the outer surface of the retractable reset frame.

[0009] Furthermore, the downward trajectory of the lifting hook passes through the hollow center of the supporting moving disc, and a rotating connecting rod is installed inside the supporting moving disc. A fitting semicircular plate is installed at the front end of the rotating connecting rod, and the fitting semicircular plate is fitted to the outer surface of the lifting hook.

[0010] Furthermore, a second rotating rod is installed on the outer surface of the first rotating rod, and the first rotating rod and the second rotating rod are designed with multiple sets of end rotating connections. The vertical sliding frame and the two ends of the first rotating rod slide vertically up and down along the inside of the vertical sliding frame, and a rotary drive motor is installed on the upper surface of the bottom support plate.

[0011] Furthermore, an auxiliary lifting worm gear is installed on the outer surface of the output end of the rotary drive motor, and the extension frame limiter is internally nested on the outer surface of the auxiliary lifting worm gear. The hollow part of the connection between the extension frame limiter and the auxiliary lifting worm gear is threaded, and a support buffer spring is installed on the side of the first rotating rod.

[0012] Furthermore, the top of the support buffer spring is fixedly installed on the outer surface of the second rotating rod, and a front support rod is installed on the lower top surface of the extension frame limiter. The inner surface of the vertical sliding frame contacts the outer end surface of the second rotating rod to form a sliding structure, and the rotary drive motor meshes with the extension frame limiter through the outside of the auxiliary lifting worm gear to form a transmission structure.

[0013] Furthermore, a reset push spring is installed on the outer surface of the supporting movable disk, and the front end of the reset push spring abuts against the outer surface of the rotating connecting rod. A fitting limit frame is installed on the outer surface of the supporting movable disk, and the movement of the rotating connecting rod is limited and slid along the inside of the fitting limit frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are: When the lifting equipment needs to be lifted, the auxiliary lifting worm is rotated accordingly by controlling the forward and reverse rotation of the rotary drive motor, thereby driving the extension frame limit as a whole. At this time, the cooperation between the first rotating rod, the second rotating rod and the support buffer spring will make the lifting process of the equipment very efficient and stable. This design allows the equipment to lift items more stably, and the items will not swing significantly during the lifting process, and it will not affect the overall bottom stability of the equipment. Furthermore, precise position control is required. The retraction and reset frame is directly activated to rotate and retract the lifting hook. At this time, the inside of the contact semicircular plate will continue to contact the outer surface of the lifting hook, and the reset push spring will keep the contact semicircular plate tightly clamped inward through the rotating connecting rod. This design makes the steel cable more stable and comprehensive during the recovery and ascent process, and can assist in the horizontal retraction function, making the equipment more practical and stable. Furthermore, during the movement of the rotating connecting rod, it will continuously adhere to the interior of the fitting limit frame, while the position of the supporting moving disc will move synchronously with the movement of the retractable reset frame.

[0017] 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.

[0018] Example 1: Please refer to Figure 2 , Figure 3 and Figure 4 This utility model provides the following technical solution: a bidirectional anti-sway lifting device, including a bottom support plate 1, a vertical sliding frame 3 installed on the upper surface of the bottom support plate 1, and a retraction stabilizing mechanism for moving the extension frame limit 2 up and down inside the vertical sliding frame 3. The retraction stabilizing mechanism includes the vertical sliding frame 3, such as... Figure 2 As shown, a first rotating rod 4 is installed on the upper surface of the bottom support plate 1, and horizontal sliding inner grooves 11 are provided on the left and right sides of the extension frame limit 2. The interior of the horizontal sliding inner grooves 11 is equipped with a fitting auxiliary mechanism to support the lifting hook 13.

[0019] like Figure 2 , Figure 3 and Figure 4 The technical solution shown addresses the problem that lifting operations often rely solely on linear devices like steel cables, leading to significant swaying of the object during ascent, which can even affect the overall stability of the equipment. The solution discloses a method where: a second rotating rod 5 is mounted on the outer surface of the first rotating rod 4, and the first and second rotating rods 4 are connected by multiple sets of end-rotating connections. The vertical sliding frame 3 slides vertically up and down along the interior of the first rotating rod 4 at both ends. A rotary drive motor 7 is mounted on the upper surface of the bottom support plate 1, and an auxiliary lifting worm gear 8 is mounted on the outer surface of the output end of the rotary drive motor 7. Figure 3As shown, the extension frame limit 2 is nested inside and installed on the outer surface of the auxiliary lifting worm gear 8. The hollow part of the connection between the extension frame limit 2 and the auxiliary lifting worm gear 8 is threaded. A support buffer spring 6 is installed on the side of the first rotating rod 4. The top of the support buffer spring 6 is fixedly installed on the outer surface of the second rotating rod 5. A front support rod 9 is installed on the lower top surface of the extension frame limit 2. The inner surface of the vertical sliding frame 3 contacts the outer surface of the end of the second rotating rod 5 to form a sliding structure. The rotary drive motor 7 forms a transmission structure through the meshing of the auxiliary lifting worm gear 8 with the extension frame limit 2.

[0020] When the working position of the extension frame limit 2 needs to be adjusted, the rotary drive motor 7 fixedly installed on the upper surface of the bottom support plate 1 is directly started. As the auxiliary lifting worm gear 8 fixedly installed on the outer surface of the output end of the rotary drive motor 7 is driven to rotate synchronously, the extension frame limit 2 is nested outside the auxiliary lifting worm gear 8, and the contact surface between the extension frame limit 2 and the auxiliary lifting worm gear 8 is internally threaded. Therefore, the extension frame limit 2 will move up and down accordingly as the auxiliary lifting worm gear 8 rotates. As the extension frame limit 2 moves, the first rotating rod 4 and the second rotating rod 5 rotatably installed on the lower surface of the extension frame limit 2 will be driven to rotate and retract simultaneously. Because the first rotating rod 4 and the second rotating rod 5 have a multi-group mutually rotating design, the compression operation of the first rotating rod 4 and the second rotating rod 5 is more stable. Figure 4 As shown, the vertical movement of the first rotating rod 4 and the second rotating rod 5 is limited by sliding along the interior of the vertical sliding frame 3 fixedly installed on the upper surface of the bottom support plate 1. During the movement of the first rotating rod 4, the support buffer spring 6 fixedly installed on the outer surface will be driven synchronously. The movement of the support buffer spring 6 is fixedly installed on the outside of the second rotating rod 5. Therefore, the contact between the first rotating rod 4 and the second rotating rod 5 will be buffered due to the design of the support buffer spring 6. At the same time, the front support rod 9 installed on the lower surface of the extension frame limit 2 will extend or retract accordingly. When the first rotating rod 4 and the second rotating rod 5 rotate, the two ends of the connecting rod between the first rotating rod 4 and the second rotating rod 5 can slide along the interior of the bottom support plate 1. Moreover, the vertical sliding frame 3 and the first rotating rod 4 and the second rotating rod 5 are not in a tight fit. The equipment will not be locked when it moves. Therefore, it can adapt to the distance changes in lifting height in the working environment. This design makes the use of the equipment more efficient and stable.

[0021] Example 2: Figure 1 , Figure 5 and Figure 6The technical solution shown addresses the problem that the upward movement of the steel cable within the equipment relies primarily on traction, lacking a horizontal retraction function, thus hindering the equipment's practicality and stability. The solution discloses a following: a contacting auxiliary mechanism includes a supporting movable disc 12, with its left and right sides slidably mounted inside a horizontal sliding inner groove 11. A retraction reset frame 10 is installed inside the extension frame limit 2, and the end of the lifting hook 13 is fixedly mounted on the outer surface of the retraction reset frame 10. Figure 5 As shown, the downward trajectory of the lifting hook 13 passes through the hollow center of the supporting movable disc 12, and a rotating connecting rod 15 is installed inside the supporting movable disc 12. A fitting semicircular plate 14 is installed at the front end of the rotating connecting rod 15, and the installation position of the fitting semicircular plate 14 is fitted to the outer surface of the lifting hook 13. A reset push spring 17 is installed on the outer surface of the supporting movable disc 12, and the front end of the reset push spring 17 abuts against the outer surface of the rotating connecting rod 15. A fitting limit frame 16 is installed on the outer surface of the supporting movable disc 12, and the movement of the rotating connecting rod 15 is limited and slid along the inside of the fitting limit frame 16.

[0022] The working position of the lifting hook 13 needs to be precisely adjusted during the operation. First, the lifting hook 13 is fixed to the item to be removed. After that, the retraction and retraction frame 10, which is nested and slidably installed inside the extension frame limit 2, is started to rotate and retract. At this time, as the lifting hook 13 slides upward, the outer surface of the lifting hook 13 will continue to maintain a stable fit with the inner surface of the contact semicircular plate 14, and the outer surface of the contact semicircular plate 14 will be continuously pressed inward by the rotating connecting rod 15. When the rotating connecting rod 15 is pressed, it will slide laterally along the inside of the support moving disc 12. Since the support moving disc 12 is slidably nested inside the horizontal sliding inner groove 11 opened at the corresponding positions on the left and right sides of the extension frame limit 2, as Figure 6 As shown, the contact position of the semicircular plate 14 remains stable, and the end of the rotating connecting rod 15 corresponds to the return push spring 17. Since the other end of the return push spring 17 is fixedly installed on the outer surface of the supporting moving disc 12, the return push spring 17 will tightly contact the outside of the lifting hook 13 with the semicircular plate 14 through the rotating connecting rod 15. The retraction rotation trajectory of the contact limit frame 16 will follow the inside of the contact limit frame 16 fixedly installed on the outer surface of the supporting moving disc 12. This design makes the use of the equipment more stable and precise.
