[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] In the present invention, a plurality of lifting brackets 2 are arranged side by side, and are hung between two adjacent lifting brackets 2, and the tops of the plurality of lifting brackets 2 are all connected to the lifting beam 1; when in use, the lifting brackets 2 corresponding to the number of containers are moved to the top of the container through the lifting beam 1, the lifting bracket 2 is lowered, and the lifting connection assembly is horizontally movably connected to the lifting bracket 2. When the structure of the container deviates, the lifting connection assembly is displaced on the lifting bracket 2, thereby adapting to the interface of the container, and then the telescopic connecting rod 8 is driven to move through the sliding bracket 3, thereby driving the lifting connection assembly to rotate along its own axis. When the lifting connection assembly is in contact with the limiting structure, the lifting connection assembly is locked. When one or more of the lifting connection assemblies are not locked, the telescopic connecting rod 8 connected to the locked lifting connection assembly contracts, and the other lifting connection assemblies continue to rotate under the drive of the telescopic connecting rod 8 until they are locked.

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

[0029] In an optional solution, vertically arranged sliding holes 20 are provided at the four corners of the hanging bracket 2, the sliding holes 20 penetrate the hanging bracket 2, the sliding holes 20 are arranged in a runway shape, the top of the sliding holes 20 is connected with a sliding groove 16, the sliding groove 16 is arranged in a runway shape, and the sliding groove 16 is arranged coaxially with the sliding hole 20;

[0030] The hanging connection component is slidably connected in the sliding hole 20 , and the elastic component is arranged in the sliding hole 20 and abuts against the hanging connection component.

[0031] Specifically, the so-called runway shape refers to a shape with a rectangular middle portion and semicircular ends; the sliding hole 20 and the sliding groove 16 are both arranged along the width direction of the hanging bracket 2.

[0032] In an optional scheme, the lifting connection assembly includes a rotating shaft 22 slidably connected in the sliding hole 20, the rotating shaft 22 is vertically arranged, the bottom end of the rotating shaft 22 passes through the sliding hole 20 and is coaxially fixed with a clamping joint 17, the top end of the rotating shaft 22 passes through the sliding hole 20 and is coaxially rotatably connected with a sliding shaft seat 14, the sliding shaft seat 14 is slidably connected in the sliding groove 16, the top end of the rotating shaft 22 passes through the sliding shaft seat 14 and is fixed with a hinged rod 12, the hinged rod 12 is perpendicular to the axis of the rotating shaft 22, and the end of the hinged rod 12 away from the rotating shaft 22 is hinged to the telescopic connecting rod 8.

[0033] Specifically, the rotating shaft 22 is vertically arranged in the sliding hole 20 and slides along the length direction of the sliding hole 20 and the sliding groove 16. When 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 in the production and assembly process of the lifting bracket 2 and the sliding bracket 3. When there is no error, the rotating shaft 22 maintains its original shape under the action of the elastic component.

[0034] In an optional solution, the elastic component includes two bolts 18, which are coaxially arranged and threadedly connected to the hanging bracket 2. One end of the bolt 18 extending into the hanging bracket 2 is fixedly connected to one end of the 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] There are multiple groups of elastic components, so as to ensure that the rotating sleeve 19 can keep the rotating shaft 22 in a vertical state when there is no external force, and always have elastic force to restore to the vertical state when there is an external force.

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

[0037] In an optional scheme, the limiting structure includes two limiting rods 11 fixedly connected to the top of the rotating shaft 22, the two limiting rods 11 are arranged horizontally, the two limiting rods 11 are perpendicular to each other, and limiting plates 9 are arranged on the opposite sides of the rotating shaft 22, the limiting plates 9 are vertically fixedly connected to the lifting bracket 2, and a limiting groove 10 is provided on the limiting plate 9, and the limiting rod 11 is detachably connected to the limiting groove 10, and a positioning plate 15 is hinged on the side where the two limiting plates 9 are away from each other, and the top of the positioning plate 15 is fixedly connected to the limiting sleeve, and a limiting ball is slidably connected in the limiting sleeve, and the bottom end of the limiting ball extends out of the limiting sleeve, and the limiting ball does not fall out of the limiting sleeve. A top spring is passed through the limiting sleeve, and the top end of the top spring is fixedly connected 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, and 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 articulated rod 12 to move, and the articulated rod 12 drives the rotating shaft 22 to rotate around its own axis to achieve the locking of the container. When one or more of the card joints 17 are not locked, the limit rod 11 on the rotating shaft 22 connected to the locked card joint 17 falls into the limit groove 10 and contacts with the limit groove 10. At this time, the telescopic link 8 contracts, and the other telescopic links 8 contract and continue to move under the drive of the sliding bracket 3 until the limit rod 11 falls into the limit groove 10 and contacts with the limit groove 10. At this time, the locking is completed. When the locking is completed, the limit 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 disengaged 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 an optional solution, a plurality of sliding seats 24 are fixedly connected to the bottom end of the sliding bracket 3, and the plurality of sliding seats 24 are distributed in an array.

The lifting bracket 2 is fixedly connected to a mounting seat 7, and a telescopic cylinder 6 is fixedly connected to the mounting seat 7. The telescopic end of the telescopic cylinder 6 is fixedly connected to the sliding bracket 3.

[0040] The extension or contraction of the telescopic end of the telescopic cylinder 6 drives the sliding bracket 3 to move along the length direction of the hanging bracket 2, and then drives the rotating shaft 22 to rotate through the telescopic connecting rod 8.

[0041] In an optional solution, two adjacent sliding brackets 3 are connected via a first connecting rod 5 .

[0042] A plurality of sliding brackets 3 can be driven to move synchronously by one telescopic cylinder 6 .
