Description

Technical Field

[0001] The utility model relates to the field of container design, in particular to a container and a lifting device. Background Art

[0002] The transfer of containers between different locations is mainly carried out by hoisting, that is, using a crane to hook the lifting points of the container and lift it up.

[0003] For containers with special lengths and uneven internal weight distribution, multi-point lifting is required, so a hook needs to be installed in the middle of the top surface of the container. Currently, the installed hook is usually welded directly to the top of the container body, and the hook protrudes and is higher than the top corner fittings of the container body. During daily stacking, the bottom of the upper container can only be placed on the protruding hook surface of the lower container, which causes the corner fittings of the container to be misaligned, resulting in uneven stacking and relative slippage, and poor stacking safety.

[0051] like Figure 1-Figure 2 As shown, in one embodiment of the utility model, a container is provided, comprising:

[0052] Box 10;

[0053] The hook 20 is pivotally connected to the top surface 12 of the box 10 and the angle between the hook and the top surface 12 of the box 10 is adjustable;

[0054] The hook 20 is configured to be placed flat on the top surface 12 of the box body 10 in the stacking state and the height of the highest point of the hook 20 does not exceed the top plane of the top corner fitting 11 of the box body 10 (that is, the height of the highest point of the hook 20 is lower than the top plane of the top corner fitting 11, or the highest point of the hook 20 is flush with the top plane of the top corner fitting 11), and to pivot to the upright state in the lifting state to be connected to the sling and lift the box body 10.

[0055] Specifically, the top corner fittings 11 are usually arranged at the four corners of the box body 10. In the stacking state, the hook 20 is placed flat on the top surface 12 of the box body 10 and the height of the highest point of the hook 20 does not exceed the top plane of the top corner fittings 11 of the box body 10, which will not affect the upper and lower stacking of containers, and the containers arranged up and down are stacked neatly; during lifting, the hook 20 is pivoted to the upright state, and a lifting rope such as a lifting wire rope is connected to the hook 20 for lifting.

[0056] Compared with the prior art, the solution of this embodiment can well solve the problem that the welding hook protrudes and is higher than the top corner fitting of the box body 10 in the conventional multi-point lifting solution. During daily stacking, the bottom of the upper container is no longer placed on the protruding hook surface of the lower container, but is placed on the top of the lower container, and the bottom of the upper container does not touch the hook of the lower container whose height does not exceed the top corner fitting of the box body, so that the corner fittings of the upper and lower containers can be aligned, the containers are stacked neatly, and relative slippage will not occur, making the stacking and storage of containers safer and more reliable.

[0057] The design structure of this embodiment is simple, the cost is low, the safety is good, the stacking and lifting operations are simple, and the efficiency is significantly improved.

[0058] refer to Figure 1 In some embodiments, there are two hooks 20 , and the two hooks 20 are respectively located on two top longitudinal beams 13 on both sides of the width direction of the top surface 12 , and are both located in the middle part of the length direction of the top longitudinal beam 13 .

[0059] Specifically, the top longitudinal beam 13 extends along the length direction of the box body 10, and a hook 20 is respectively provided in the middle part of the length direction of the two top longitudinal beams 13, which can be connected to the two lifting points in the width direction of the middle part of the box body 10 during lifting, so as to apply a lifting force to the middle part of the box body 10 in a balanced manner; after combining with the lifting of the top corner piece 11 of the box body 10, force can be evenly applied to different parts of the top surface 12 of the box body 10 at the same time, the lifting strength is greater, and the energy storage container with special length or uneven weight distribution in the box can be lifted in a balanced manner, so as to avoid major safety accidents caused by tilting of the box body 10 due to uneven weight distribution during lifting, thereby greatly improving the safety of lifting and transportation.

[0060] refer to Figure 3-Figure 5 In some embodiments, the hook 20 comprises:

[0061] A hook body 21, wherein a pivot shaft 211 is provided on a side of the hook body 21;

[0062] A base 23 is mounted on the top surface 12 of the box 10;

[0063] The shaft sleeve 22 is sleeved on the pivot shaft 211 with clearance fit, and the shaft sleeve 22 is fixed to the surface of the base 23 .

[0064] Specifically, the above-mentioned base 23 can be arranged at a preset position of the top surface 12 of the box body 10 as needed; the sleeve 22 is firmly installed on the base 23 by welding or the like, and the pivot shaft 211 of the hook body 21 can pivot in the sleeve 22, so that the hook body 21 can freely switch between the horizontal and upright states.

[0066] Specifically, if the extension direction of the pivot axis 211 of the hook 20 is not consistent with the length direction of the box 10 (for example, pointing to the middle of the top surface 12 of the box 10), the component force of the pulling force on the sling will be transmitted to the top surface 12 of the box 10 along the extension direction of the pivot axis 211 during lifting, increasing the load on the top surface 12. The present application can avoid this problem, and the component force of the pulling force on the sling will only be transmitted along the top longitudinal beam 13 at the edge of the box 10, and will not be transmitted to the top surface 12 of the box to increase its load.

[0067] refer to Figure 5 In some embodiments, the sleeve 22 has a circular arc or square through groove on one side of the surface of the base 23, and the through groove cooperates with the base 23 to form an axial hole for the pivot shaft 211 to pass through.

[0068] In this embodiment, during installation, the pivot shaft 211 is placed on the surface of the base 23, and the through groove on one side of the sleeve 22 covers the surface of the pivot shaft 211, so as to cooperate with the base 23 to fix the pivot shaft 211. The arc-shaped or square through groove is convenient for matching and installing with the pivot shaft 211.

[0069] refer to Figure 3 In some embodiments, the surface of the hook body 21 is provided with a through hole 212 for connecting the sling. The hook body 21 can be semicircular or arched, and the through hole 212 in the middle is convenient for the sling to pass through and connect.

[0070] like Figure 6-Figure 8 In one embodiment of the utility model, a lifting device is provided, which includes:

[0071] A boom 1, wherein both ends of the boom 1 are provided with hanging components 1-1, and are configured to be suspended above the container in a hoisting state, and the two hanging components 1-1 are respectively close to both ends of the length direction of the container (the length direction of the boom 1 is consistent with the length direction of the container);

[0072] A first sling 2, wherein the first sling 2 is configured to be connected to the hanging component 1-1 at one end and connected to the hook 20 on the top surface 12 of the container at the other end in a hoisting state to hoist the container;

[0073] The second sling 3 is configured to have one end connected to the hanging component 1-1 and the other end connected to the top corner piece 11 of the container end adjacent to the hanging component 1-1 in the hanging state.

[0074] When lifting is required, the lifting rod 1 is suspended above the container and the two hanging components 1-1 are respectively close to the two ends of the container in the length direction. Each hanging component 1-1 at both ends of the lifting rod 1 is connected to the hook 20 through the first lifting rope 2 and connected to the top corner piece 11 at the end of the container through the second lifting rope 3, so as to be connected to the top surface 12 of the container through various types of lifting ropes, and the lifting strength is large; and multi-point lifting can apply force from multiple different parts to lift the container in a balanced manner, so as to avoid major safety accidents caused by tilting of the box body 10 due to uneven weight distribution during lifting.

[0075] refer to Figure 6 In some embodiments, the rod body of the suspension rod 1 includes four rod walls 1-2, and the four rod walls 1-2 are arranged in sequence and connected along the circumference of the rod body. The hanging component 1-1 is passed through two non-adjacent rod walls 1-2 and is welded and fixed to the rod walls 1-2.

[0076] Specifically, the cross section of the suspension rod 1 is square, and the hanging component 1-1, such as the hanging ear 1-1a, is inserted through the circumferential surface of the rod body near the end of the suspension rod 1, and the sling passes through and is fixed through the through hole of the hanging ear 1-1a. In this embodiment, the hanging component 1-1 is assembled on the suspension rod 1 from top to bottom, which is convenient to operate, and is welded after assembly, which can ensure the connection strength and safety of the hanging component 1-1 and the rod body.

[0077] refer to Figure 8 In some embodiments, each of the hanging components 1-1 is connected to two second slings 3, and the other ends of the two second slings 3 are respectively connected to the top corner pieces 11 on both sides of the width direction of the container end corresponding to the hanging component 1-1; and

[0078] Each of the hanging components 1 - 1 is connected to two first slings 2 , and the other ends of the two first slings 2 are respectively connected to hooks 20 arranged at the middle of the length direction of the two top longitudinal beams 13 .

[0079] Specifically, through the arrangement of this embodiment, each hanging component 1-1 is connected to the top surface 12 of the container through four lifting ropes, and the lifting strength is sufficient; and the energy storage container adopts four top corner pieces 11 + two middle hooks 20 for a total of six points of lifting, which can balance the lifting of energy storage containers with special length or uneven weight distribution in the box, avoid major safety accidents caused by tilting of the box body 10 due to uneven weight distribution during lifting, and greatly improve the safety of lifting and transportation.

[0080] refer to Figure 8In some embodiments, the angle between the first sling 2 and / or the second sling 3 and the top surface 12 of the container is configured to be greater than or equal to 60°.

[0081] Specifically, the angle between the first sling 2 and / or the second sling 3 and the top surface 12 of the container is greater than or equal to 60°, which can increase the vertical force component to ensure sufficient lifting force. It has been verified through actual lifting that the container can be lifted smoothly without increasing the energy consumption of the lifting equipment by adopting this design angle, and the shape of the container body 10 is stable during the lifting process. More preferably, the length of the first sling 2 and / or the second sling 3 is greater than 5m, so as to facilitate the flexible installation of lifting facilities.
