Description

Technical Field

[0001] This utility model belongs to the field of container spreader technology, and in particular relates to a multi-set automatic compensation container spreader. Background Technology

[0002] With the development of the wind power industry, the number of onshore and offshore wind farms has increased significantly. Due to the large variety and quantity of components in each wind turbine, the required tools and lifting equipment are countless, which increases the pressure on transportation and storage. If all containers of different sizes are directly lifted by the main crane, it is not only cumbersome but also inefficient. Therefore, it is considered to use two or more sets of small and medium-sized containers of the same specifications to lift them side by side. However, the interfaces of containers are relatively precise and sealed, so there will be obvious deviations after two or more sets are placed side by side, and it is impossible to accurately ensure that the lock head of the locking device is in the locked or unlocked state.

[0003] To address this, a multi-set automatic compensation container spreader is proposed. Utility Model Content

[0010] In the multi-set automatic compensation container spreader of this utility model, the elastic component includes two bolts, which are coaxially arranged and threadedly connected to the lifting bracket. One end of each bolt extending into the lifting bracket is fixedly connected to one end of a spring, and the other end of the spring is fixedly connected to a rotating sleeve.

[0011] In the multi-set automatic compensation container spreader of this utility model, the limiting structure includes two limiting rods fixed to the top of the rotating shaft.

A fixed limiting sleeve is provided, and a limiting ball is slidably connected inside the limiting sleeve. The bottom end of the limiting ball extends out of the limiting sleeve and does not come out of the limiting sleeve. A top spring is inserted inside the limiting sleeve, and the top end of the top spring is fixedly connected to the top end of the limiting sleeve. The bottom end of the top spring abuts against the limiting ball. The limiting sleeve is located between the two limiting plates. The bottom end of the limiting sleeve is higher than the top end of the limiting plate, and the bottom end of the limiting ball is lower than the top end of the limiting plate.

[0016] In this invention, multiple lifting supports are arranged side by side, with adjacent lifting supports hooked together. The tops of all lifting supports are connected to a lifting beam. In use, the lifting supports corresponding to the number of containers are moved above the containers via the lifting beam. The lifting supports then descend, and the lifting connecting components are horizontally and movably connected to the lifting supports. When the container structure deviates, the lifting connecting components shift on the lifting supports, thus adapting to the container interface. Then, the sliding support drives the telescopic connecting rod to move, thereby causing the lifting connecting components to rotate along their own axis. When the lifting connecting components come into contact with the limiting structure, they are locked. When one or more of the lifting connecting components are not locked, the telescopic connecting rod connected to the locked lifting connecting components retracts, and the other lifting connecting components continue to rotate under the drive of the telescopic connecting rod until they are locked.

[0017] This invention can compensate for errors generated during the production and assembly of lifting brackets and sliding brackets, thereby ensuring that the lifting connection components are properly connected to the container and that the lifting connection components are locked to the container.

[0024] 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.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Reference Figures 1 to 4 This utility model discloses a multi-set automatic compensation container spreader, including: at least two lifting brackets 2 arranged along the width direction, the top ends of the multiple lifting brackets 2 are connected by a lifting beam 1, a sliding bracket 3 is slidably connected to the top surface of the lifting bracket 2, the sliding bracket 3 slides along the length direction of the lifting bracket 2, lifting connecting components are horizontally movably connected at the four corners of the lifting bracket 2, the top end of the lifting connecting component extends out of the lifting bracket 2 and is hinged to a telescopic link 8, the other end of the telescopic link 8 is hinged to the sliding bracket 3, the bottom end of the lifting connecting component extends out of the lifting bracket 2 and is connected to the container, at least two sets of elastic components and a limiting structure are provided between the lifting connecting component and the lifting bracket 2, and the multiple sets of elastic components are arranged at equal intervals from top to bottom.

[0027] In this invention, multiple lifting brackets 2 are arranged side by side, with adjacent lifting brackets 2 being hooked together. The tops of all lifting brackets 2 are connected to the lifting beam 1. In use, the lifting brackets 2 corresponding to the number of containers are moved above the containers via the lifting beam 1. The lifting brackets 2 descend, and the lifting connecting components are horizontally and movably connected to the lifting brackets 2. When the container structure deviates, the lifting connecting components are displaced on the lifting brackets 2, thereby adapting to the container interface. Then, the sliding bracket 3 drives the telescopic connecting rod 8 to move, which in turn drives the lifting connecting components to rotate along their own axis. When the lifting connecting components are in contact with the limiting structure, the lifting connecting components are locked. When one or more of the lifting connecting components are not locked, the telescopic connecting rod 8 connected to the locked lifting connecting components retracts, and the other lifting connecting components continue to rotate under the drive of the telescopic connecting rod 8 until they are locked.

[0028] This invention can compensate for errors generated during the production and assembly of the lifting bracket 2 and the sliding bracket 3, thereby ensuring that the lifting connection component is properly connected to the container and that the lifting connection component is locked to the container.

[0029] In one alternative, vertically arranged sliding holes 20 are provided at each of the four corners of the hoisting bracket 2. The sliding holes 20 penetrate the hoisting bracket 2 and are designed in the shape of a racetrack. The top of the sliding holes 20 is connected to a sliding groove 16, which is also designed in the shape of a racetrack and is coaxial with the sliding holes 20.

[0030] The hoisting connection assembly is slidably connected within the sliding hole 20, and the elastic component is disposed within the sliding hole 20 and abuts against the hoisting connection assembly.

[0031] Specifically, the so-called runway shape refers to a shape with a rectangular middle section and semi-circular ends; the sliding holes 20 and the sliding grooves 16 are both set along the width direction of the hoisting bracket 2.

[0032] In one alternative embodiment, the hoisting connection assembly includes a rotating shaft 22 slidably connected within a sliding hole 20. The rotating shaft 22 is vertically positioned, with its bottom end extending out of the sliding hole 20 and coaxially fixed to a snap connector 17. The top end of the rotating shaft 22 extends out of the sliding hole 20 and is coaxially rotatably connected to a sliding shaft seat 14. The sliding shaft seat 14 is slidably connected within a sliding groove 16. The top end of the rotating shaft 22 extends out of the sliding shaft seat 14 and is fixedly connected to a hinge rod 12. The hinge rod 12 is perpendicular to the axis of the rotating shaft 22, and the end of the hinge rod 12 away from the rotating shaft 22 is hinged to a telescopic connecting rod 8.

[0033] Specifically, the rotating shaft 22 is vertically set in the sliding hole 20 and slides along the length direction of the sliding hole 20 and the sliding groove 16. When a deviation occurs, the rotating shaft 22 slides along the length direction of the sliding hole 20 and the sliding groove 16 to compensate for the errors generated by the lifting bracket 2 and the sliding bracket 3 during production and assembly. When there is no error, the rotating shaft 22 maintains its original shape under the action of the elastic component.

[0034] In one alternative embodiment, the elastic component includes two bolts 18, which are coaxially arranged and threaded onto the lifting bracket 2. One end of each bolt 18 extending into the lifting bracket 2 is fixedly connected to one end of a spring 21, and the other end of the spring 21 is fixedly connected to a rotating sleeve 19. The rotating sleeve 19 is rotatably connected to the outside of the rotating shaft 22 and slidably connected to the sliding hole 20.

[0035] Multiple sets of elastic components are provided to ensure that the rotating sleeve 19 can keep the rotating shaft 22 in a vertical state when no external force is applied, and always have an elastic force to restore it to a vertical state when an external force is applied.

[0036] Specifically, bolt 18 extends into the hoisting bracket 2 and is fixed to one end of spring 21. The other end of spring 21 is fixed to the outer wall of rotating sleeve 19. Both bolts 18 and both springs 21 are coaxially arranged, and the axis of bolt 18 is parallel to the length direction of sliding hole 20 and sliding groove 16, thereby ensuring that the rotating shaft 22 remains in its original state when there is no error.

[0037] In one alternative embodiment, the limiting structure includes two limiting rods 11 fixed to the top of the rotating shaft 22. Both limiting rods 11 are horizontally arranged and perpendicular to each other. Limiting plates 9 are provided on opposite sides of the rotating shaft 22. The limiting plates 9 are vertically fixed to the hoisting bracket 2. Limiting grooves 10 are provided on the limiting plates 9. The limiting rods 11 are detachably connected to the limiting grooves 10. Positioning plates 15 are hinged to the opposite sides of the two limiting plates 9. A limiting sleeve is fixed to the top of the positioning plate 15. A limiting ball is slidably connected inside the limiting sleeve. The bottom end of the limiting ball extends out of the limiting sleeve and does not come out of the limiting sleeve. A top spring passes through the limiting sleeve. The top end of the top spring is fixed to the top end of the limiting sleeve, and the bottom end of the top spring abuts against the limiting ball. The limiting sleeve is located between the two limiting plates 9. The bottom end of the limiting sleeve is higher than the top end of the limiting plate 9, and the bottom end of the limiting ball is lower than the top end of the limiting plate 9.

[0038] The movement of the telescopic link 8 drives the hinge rod 12 to move, and the hinge rod 12 drives the rotating shaft 22 to rotate around its own axis to lock the container. When one or more of the locking connectors 17 are not locked, the limiting rod 11 on the rotating shaft 22 connected to the locked locking connector 17 falls into the limiting groove 10 and makes limiting contact with the limiting groove 10. At this time, the telescopic link 8 retracts, and the other telescopic links 8 continue to retract and move under the drive of the sliding bracket 3 until the limiting rod 11 falls into the limiting groove 10 and makes limiting contact with the limiting groove 10. At this time, the locking is completed. When the locking is completed, the limiting rod 11 pushes the positioning plate 15, and the limiting sleeve is located between the two limiting plates 9. The bottom end of the limiting sleeve is higher than the top end of the limiting plate 9, and the bottom end of the limiting ball is lower than the top end of the limiting plate 9. At this time, the limiting sleeve is dislodged from between the two limiting plates 9, and the positioning plate 15 tilts, indicating that the position has been locked. The staff observes the state of the positioning plate 15 to determine the locking state.

[0039] In one alternative, the bottom end of the sliding bracket 3 is fixedly connected to multiple sliding seats 24, which are arranged in an array. The sliding seats 24 are slidably connected to the slide rail 4, which is fixedly connected to the hoisting bracket 2. The slide rail 4 is arranged along the length of the hoisting bracket 2. The hoisting bracket 2 is fixedly connected to the mounting seat 7, and the mounting seat 7 is fixedly connected to the telescopic cylinder 6. The telescopic end of the telescopic cylinder 6 is fixedly connected to the sliding bracket 3.

[0040] The telescopic cylinder 6 extends or shortens, causing the sliding bracket 3 to move along the length of the hoisting bracket 2, which in turn drives the rotating shaft 22 to rotate via the telescopic connecting rod 8.

[0041] In one alternative, two adjacent sliding supports 3 are connected by a first link 5.

[0042] Multiple sliding supports 3 can be moved synchronously by a single telescopic cylinder 6.

[0043] In one alternative, both ends of the hoisting bracket 2 are fixedly connected to a connecting seat 25, the connecting seat 25 is connected to a connecting piece 26, and the connecting piece 26 is connected to the hoisting beam 1.

[0044] The hoisting bracket 2 is connected to the hoisting beam 1 via the connecting seat 25 and the connecting piece 26.

[0045] Specifically, a connector 26 is hinged to the connecting seat 25. The connector 26 is hinged to the lifting beam 1, and the hinge axis between the connector 26 and the lifting beam 1 is perpendicular to the hinge axis between the connecting seat 25 and the connector 26.
