Description

Technical Field

[0001] This utility model relates to the field of hoisting, and in particular to a sling for lifting and hoisting. Background Technology

[0002] Wire rope slings are commonly used lifting and hoisting slings. They consist of high-strength steel wire ropes connected to end accessories such as hooks and shackles. Utilizing the high load-bearing capacity of steel wire ropes, they are widely used in factories, construction sites, logistics facilities, and other scenarios for hoisting heavy objects such as steel and equipment. They are characterized by high strength, wear resistance, and resistance to high and low temperatures, making them suitable for various environments. However, regular inspection of the rope for wear and broken wires is necessary to ensure safety.

[0003] In existing technology, operators connect the hook on the rope to the object to be lifted, and then start the crane to carry out the lifting operation. However, since existing rigging often only has one hook, it may be necessary to install multiple ropes on the surface of the object when lifting larger objects, twist the ropes into one end, and connect the end to the hook before continuing the lifting operation. This not only prolongs the lifting process, but if the rope end is not at the center point of the object, it may also cause the object to tilt, accelerate rope wear, and cause engineering accidents. Therefore, a new type of rigging for lifting is proposed. Utility Model Content

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A lifting and hoisting sling includes: a protective mechanism, wherein the protective mechanism includes a protective shell;

[0006] A splitting and joining mechanism is provided inside the protective mechanism. The splitting and joining mechanism includes a second protective shell, which is connected to the inside of the first protective shell. The top inner wall of the second protective shell has two splitting holes, and the bottom inner wall of the second protective shell has a joining hole.

[0007] A rope mechanism located inside the splitting and connecting mechanism, the rope mechanism comprising several sub-ropes, one end of each of the sub-ropes being connected to a main rope;

[0008] A hanging mechanism is provided at the bottom of the rope mechanism. The hanging mechanism includes a protective shell three. A limiting plate is provided inside the protective shell three. The other ends of the sub-rope and several female ropes are all connected to the upper surface of the limiting plate.

[0009] The above technical solution includes a protective shell that protects internal components, a rope separation and connection mechanism that enables rope separation and connection through separation and connection holes, a rope mechanism where the sub-rope and main rope work together to bear weight, and a limit plate in the hanging mechanism that enhances connection stability, thus improving overall hoisting safety.

[0010] As a further description of the above technical solution:

[0011] The protective mechanism also includes several external plates, which are disposed on both sides of the protective shell. The inner wall of each external plate has screw holes, and the inner wall of the middle part of the protective shell has a placement cavity.

[0012] The above technical solution allows the outer plate and screw holes of the protective mechanism to be easily fixed to the lifting equipment, ensuring a firm connection. The placement cavity provides installation space for the opening and closing mechanism, reducing external interference to the internal components.

[0013] As a further description of the above technical solution:

[0014] The separation and assembly mechanism also includes several connecting plates, all of which are detachably connected to the upper and lower surfaces of the protective shell. Several fixing bolts pass through the inner walls of the protective shell and the connecting plates.

[0015] In the above technical solution, the connecting plate of the splitting and joining mechanism is detachable, which facilitates the maintenance or replacement of internal components. The fixing bolt enhances the connection strength between the protective shell and the connecting plate, thereby improving the overall structural stability.

[0016] As a further description of the above technical solution:

[0017] The hanging mechanism also includes a hook, which is rotatably connected inside the protective shell three, and a limiting circular plate is connected to the top of the hook.

[0018] The above technical solution allows the hook of the hanging mechanism to rotate, facilitating the hanging of different weights. The limiting circular plate effectively prevents the hook from falling off during hoisting, ensuring the safety of hoisting operations and improving reliability.

[0019] As a further description of the above technical solution:

[0020] The sub-cables are slidably connected in small holes inside the protective shell, and several sub-cables are located on the same horizontal plane.

[0021] The above technical solution, in which the sub-songs are slidably connected in the small holes of the protective shell, can reduce friction during sliding, extend the service life of the sub-songs, and the sub-songs are located on the same horizontal plane, which can make the force uniform and avoid overloading of a single sub-song.

[0022] As a further description of the above technical solution:

[0023] Several of the female cables are slidably connected inside the connecting hole, and the female cables and the protective shell are located on the same vertical plane.

[0024] The above technical solution allows the main cable to slide smoothly within the connecting hole, facilitating length adjustment. The secondary cable and the protective shell are located on the same vertical plane, ensuring more direct force transmission, reducing force loss, and improving hoisting efficiency.

[0025] As a further description of the above technical solution:

[0026] Several of the external plates are located on the same horizontal plane, and the interior of the second protective shell has a cavity.

[0027] The above technical solution, with several external plates located on the same horizontal plane, can ensure force balance when connected to lifting equipment, and the cavity of the second protective shell provides space for rope movement, avoiding rope compression damage.

[0028] As a further description of the above technical solution:

[0029] The spacing between the several small holes on the inner wall of the protective shell and the placement cavity is equal, and the several small holes on the inner wall of the protective shell and the placement cavity are located on the same horizontal plane.

[0030] The above technical solution ensures that the small holes on the inner wall of the protective shell are equidistant from the placement cavity and are located on the same horizontal plane, so that the sub-slings are evenly distributed and the force is balanced, while avoiding rope twisting and ensuring a stable and orderly hoisting process.

[0031] This utility model has the following beneficial effects:

[0032] 1. In this utility model, a protective shell three, consisting of several combined main cables connected together, is hooked onto an object. When the object to be lifted is large, using only one protective shell three and lifting the object would result in a large tensile force on the sub-cables and main cable. Therefore, several sub-cables are pulled downwards, causing the protective shell three and connecting parts at the ends of the sub-cables to lift the larger part. This structure achieves the effect of smoothly lifting large objects, solving the problem in the prior art where using only one hook when lifting large objects with a crane can cause the object to tilt, accelerate rope wear, and lead to engineering accidents.

[0033] 2. In this utility model, several sub-slings are located on the same horizontal plane, the sub-slings and the protective shell are located on the same vertical plane, and the distance between the several small holes opened on the inner wall of the protective shell and the placement cavity is equal. This structure achieves a stable effect when large-volume items are lifted, solving the problem in the prior art where, when cranes use ropes and hooks to lift items, the items may be subject to wind interference, resulting in uneven force and slippage.

[0044] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0045] Reference Figures 1 to 5 The present invention provides an embodiment of a lifting and hoisting sling, comprising: a protective mechanism 100, the protective mechanism 100 comprising a protective shell 101;

[0046] The separation and joining mechanism 200 is located inside the protective mechanism 100. The separation and joining mechanism 200 includes a second protective shell 201, which is connected to the inside of the first protective shell 101. The top inner wall of the second protective shell 201 has two separation holes 204, and the bottom inner wall of the second protective shell 201 has a joining hole 205.

[0047] A rope mechanism 300 is provided inside the splitting and connecting mechanism 200. The rope mechanism 300 includes several sub-ropes 301, and one end of each sub-rope 301 is connected to a main rope 302.

[0048] The hanging mechanism 400 is located at the bottom of the rope mechanism 300. The hanging mechanism 400 includes a protective shell 3 401. A limit plate 402 is provided inside the protective shell 3 401. The other ends of the sub-rope 301 and several female ropes 302 are all connected to the upper surface of the limit plate 402.

[0049] In the above embodiment, the device is installed on the lifting end of the crane. After installation, when a small object needs to be lifted, the protective shell 3 401, which connects several merged main cables 302, hooks the object through the connecting part. When the object to be lifted is large, using only the connecting part of the protective shell 3 401 to lift the object will result in a large tension on the sub-cables 301 and main cable 302. Therefore, several sub-cables 301 are pulled downwards, and the originally merged main cable 302 is separated through two dividing holes 204, which lengthens the sub-cables 301 and shortens the main cable 302. This allows the protective shell 3 401 and connecting part at the end of the sub-cables 301 to lift the larger part, dispersing the tension on the sub-cables 301 and main cable 302, making the object more stable when lifted and reducing the probability of engineering accidents.

[0050] Reference Figure 3 The protective mechanism 100 also includes several external plates 103, which are all arranged on both sides of the protective shell 101. The inner wall of the external plate 103 is provided with screw holes 102, and the inner wall of the middle part of the protective shell 101 is provided with a placement cavity 104.

[0051] In the above embodiment, the screw holes 102 on the inner wall of the outer plate 103 are used to install and fix the components to an external crane, and the placement cavity 104 on the inner wall of the middle part of the protective shell 101 is used to provide space for component placement.

[0052] Reference Figure 3 , Figure 4 The splitting and joining mechanism 200 also includes several connecting plates 202, which can be detachably connected to the upper and lower surfaces of the protective shell 101. Several fixing bolts 203 are provided through the inner walls of the protective shell 101 and the connecting plates 202.

[0053] In the above embodiment, several connecting plates 202 are used to connect with the crane, and the protective shell 101 is disassembled and installed by removing several fixing bolts 203.

[0054] Reference Figure 2 , Figure 5 The hanging mechanism 400 also includes a hook 403, which is rotatably connected inside the protective shell 401, and a limiting circular plate is connected to the top of the hook 403.

[0055] In the above embodiment, the hook 403 is a component mainly used to contact the item, and is hook-shaped. The limiting circular plate is used to limit the movement distance of the hook 403.

[0056] Reference Figure 2 , Figure 3 Sub-cable 301 is slidably connected in a small hole inside the protective shell 101, and several sub-cables 301 are located on the same horizontal plane.

[0057] In the above embodiment, several sub-cables 301 are located on the same horizontal plane, so that the crane keeps the item in a horizontal state during the lifting process, reducing the risk of the item slipping and accidents.

[0058] Reference Figure 2 , Figure 4 Several female cables 302 are slidably connected inside the connecting hole 205, and the female cables 301 and the protective shell 401 are located on the same vertical plane.

[0059] In the above embodiment, the connecting hole 205 provides sliding guide space for the main cable 302, allowing the main cable 302 to slide flexibly along the connecting hole 205. The sub-cable 301 and the protective shell 301 are located on the same vertical plane, ensuring that the sub-cable 301 corresponds to the protective shell 301 in spatial position when it is pulled, thus maintaining the stability of the structure under stress or in operation.

[0060] Reference Figure 1 , Figure 4 Several external plates 103 are located on the same horizontal plane, and the interior of the protective shell 201 has a cavity.

[0061] In the above embodiment, several external plates 103 are located on the same horizontal plane. This layout can ensure the consistency of the horizontal position of the external plates 103 when the protective mechanism 100 is installed or subjected to force, and maintain the balance and stability of the overall structure. The cavity opened inside the protective shell 201 can provide space for the internal components to be adapted, and meet the space requirements for component arrangement.

[0062] Reference Figure 3 The distance between the several small holes opened on the inner wall of the protective shell 101 and the placement cavity 104 is equal, and the several small holes opened on the inner wall of the protective shell 101 and the placement cavity 104 are located on the same horizontal plane.

[0063] In the above embodiment, the spacing between the several small holes opened on the inner wall of the protective shell 101 and the placement cavity 104 is equal, and the two are located on the same horizontal plane. This design can make the sub-cable 301 and the main cable 302 bear force evenly, ensuring that the components connected to them maintain symmetrical stability during installation or operation, and maintaining the balance and coordination of the overall structure of the protective shell 101.

[0064] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
