[0001] The utility model relates to the technical field of slings, in particular to a pallet sling. Background Art

[0002] In the field of modern industry and logistics, slings are used as tools to lift and transport heavy objects. With the continuous development of the manufacturing industry, the trend of product diversification and large-scale production is becoming increasingly obvious, which puts higher and higher requirements on the performance, adaptability and safety of slings. Traditional slings are gradually unable to meet the precise needs of transporting some special products in terms of design and function. General slings cannot accurately locate and stably grasp products, which easily leads to shaking and imbalance during transportation, which not only affects transportation efficiency, but may also cause damage to products and the surrounding environment, and even cause safety accidents.

[0003] In the handling scenarios of similar products, the pallet handling slings available on the market for products like the WG2500 mainly focus on versatility and fail to fully consider the unique structure and mechanical properties of specific products and their pallets. When faced with the WG2500 product, this versatility cannot effectively adapt to its weight distribution, external contours, and the handling requirements after combination with wooden pallets.

[0004] When the existing general-purpose sling is connected to the WG2500 product wooden pallet, the design is not optimized for the specific size and structure of the WG2500 product wooden pallet. The shape of the connecting part does not match the pallet and cannot fit tightly to the pallet surface, resulting in a small contact area and uneven force. It cannot provide sufficient stability and firm gripping force, causing the pallet to easily slip and deflect during the lifting process, seriously affecting the continuity and reliability of the handling operation, making it difficult to keep the pallet stable during the lifting process, and increasing the risk of product falling and damage as well as injury to surrounding equipment and personnel. Therefore, a pallet sling is proposed to solve the above problems. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a pallet hoist, which aims to improve the problem in the existing technology that the pallet is prone to slipping and deflecting during the lifting process because the design is not optimized for the specific size and structure of the WG2500 product wooden pallet.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a pallet hanger, comprising a wooden pallet, wherein mounting holes are provided on the left and right sides of the wooden pallet, and special-shaped hanger frames are engaged with the inside of the two mounting holes, and the bottoms of the two special-shaped hanger frames are provided with arc-shaped corners, and the two special-shaped hanger frames respectively pass through the left and right sides of the wooden pallet, and the middle parts of the two special-shaped hanger frames are Z-shaped structures, the bottoms of the two special-shaped hanger frames are respectively engaged with the adjacent side of the inner bottom ends of the two mounting holes, and the middle parts of the two special-shaped hanger frames are respectively engaged with the side away from the inner top ends of the mounting holes, and the tops of the two special-shaped hanger frames are provided with a lifting mechanism.

[0007] As a further description of the above technical solution:

[0008] The lifting mechanism includes multiple steel ropes, and the middle and lower parts of the multiple steel ropes are fixedly installed with lock pieces 1, the bottom ends of the multiple steel ropes are respectively fixedly connected to the inside of the multiple lock pieces 1, the bottoms of the multiple steel ropes are respectively connected to the tops of two special-shaped hanger frames, the tops of the multiple steel ropes are fixedly connected with lock pieces 2, and the tops of the multiple lock pieces 2 are fixedly connected with lifting rings.

[0009] As a further description of the above technical solution:

[0010] A counterweight block is provided at the center of the top of the wooden pallet, and the bottom of the counterweight block adopts an anti-slip design.

[0011] As a further description of the above technical solution:

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Reference Figure 2-Figure 5The utility model provides an embodiment of a pallet hanger, comprising a wooden pallet 1, with mounting holes 10 on the left and right sides of the wooden pallet 1. The opening of the mounting holes 10 provides precise positioning and a stable connection position for the installation of the special-shaped hanger frame 2, so that the special-shaped hanger frame 2 can be accurately combined with the wooden pallet 1, ensuring the reliability of subsequent lifting operations. The interiors of the two mounting holes 10 are both engaged with the special-shaped hanger frame 2, and the special-shaped hanger frame 2 is a key component for realizing pallet lifting. The engaging structure between the two special-shaped hanger frames 2 and the mounting holes 10 can effectively transmit the lifting force and ensure the stability of the pallet and the product during the lifting process. The bottoms of the two special-shaped hanger frames 2 are both provided with arc-shaped corners, which can better fit with the bottoms of the mounting holes 10, thereby enhancing the horizontal stability of the special-shaped hanger frame 2. The two special-shaped spreaders 2 are respectively engaged on the left and right sides of the wooden pallet 1. This through-type design enables the special-shaped spreaders 2 to be evenly distributed on both sides of the wooden pallet 1, thereby achieving a more balanced force support for the pallet, which is conducive to the stable lifting of the pallet and the product. The middle parts of the two special-shaped spreaders 2 are both Z-shaped structures. The Z-shaped structure can form a unique snap-fitting method in the mounting hole 10, ensuring a close connection between the special-shaped spreader 2 and the wooden pallet 1, and improving the firmness of the overall structure. The bottoms of the two special-shaped spreaders 2 are respectively engaged on the adjacent side of the inner bottom end of the two mounting holes 10. The snap-fitting method of the bottom further enhances the vertical connection stability between the special-shaped spreader 2 and the wooden pallet 1, effectively preventing If loosening occurs during the lifting process, the middle parts of the two special-shaped spreader frames 2 are respectively engaged with the inner top end of the mounting hole 10 away from the side. The middle engaging position design forms a stable interlocking structure between the special-shaped spreader frame 2 and the wooden pallet 1, which greatly improves the reliability of the entire spreader system. The tops of the two special-shaped spreader frames 2 are provided with a lifting mechanism, which is connected to the top of the special-shaped spreader frame 2. It is a direct medium for transmitting external tension to the pallet, thereby realizing the lifting operation of the pallet and the product. The interior of the two special-shaped spreader frames 2 is provided with a reinforcement rod 8. The reinforcement rod 8 can enhance the internal structural strength of the special-shaped spreader frame 2 to prevent it from deformation when subjected to a large lifting force, thereby extending the service life of the special-shaped spreader frame 2. The two ends of the two reinforcement rods 8 are respectively fixedly connected Connected to the front and rear sides of the interior of the two special-shaped hanger frames 2, this fixed connection method enables the reinforcement rod 8 to effectively support and reinforce the special-shaped hanger frame 2, further improving the overall rigidity of the special-shaped hanger frame 2, and the tops of the two reinforcement rods 8 are evenly fixedly connected with multiple support rods 9. The support rods 9 serve to auxiliary support the top of the special-shaped hanger frame 2, which helps to disperse the lifting force and enhance the bearing capacity of the top of the special-shaped hanger frame 2. The tops of multiple support rods 9 are respectively fixedly connected to the internal top ends of the two special-shaped hanger frames 2. Through the fixed connection with the internal top ends of the special-shaped hanger frames 2, the support rods 9 and the reinforcement rods 8 work together to improve the overall structural stability of the special-shaped hanger frame 2 and ensure that the special-shaped hanger frame 2 can withstand large tensile forces without deformation during the lifting process.

[0029] Reference Figure 1 and Figure 2 The lifting mechanism includes multiple steel wire ropes 4. The steel wire ropes 4 are the main force-bearing components, which can effectively transmit tension and realize the function of lifting pallets and products. The middle and lower parts of the multiple steel wire ropes 4 are fixedly installed with locks 3. The locks 3 are used to fix the position of the steel wire ropes 4 to prevent them from displacing during the force-bearing process, ensuring stable force transmission. The bottom ends of the multiple steel wire ropes 4 are respectively fixedly connected to the inside of the multiple locks 3. This connection method ensures the firmness of the connection between the steel wire ropes 4 and the locks 3, so that the force can be reliably transmitted from the steel wire ropes 4 to the locks 3. The bottoms of the multiple steel wire ropes 4 are respectively connected to the tops of the two special-shaped spreader frames 2, thereby transmitting the external tension to the special-shaped spreader frame 2, driving the wooden pallet 1 and the products connected to the special-shaped spreader frame 2 to rise. The tops of the multiple steel wire ropes 4 are fixedly connected with locks 2 5, which play the role of connecting the steel wire ropes 4 and the lifting rings 6. In order to realize the smooth transmission of force between different components, the tops of multiple locks 5 are fixedly connected with lifting rings 6. The lifting rings 6 are used as the connection parts with external lifting equipment, which are convenient for connection with crane hooks, etc., to facilitate the implementation of lifting operations. A counterweight block 7 is set in the top center of the wooden pallet 1. The counterweight block 7 can adjust the center of gravity of the wooden pallet 1 and the product as a whole to make it more stable during the lifting process and prevent the pallet from shaking or tilting due to the shift of the center of gravity. The bottom of the counterweight block 7 adopts an anti-slip design. The anti-slip design can increase the friction between the counterweight block 7 and the wooden pallet 1 to prevent the counterweight block 7 from sliding during the lifting process, further ensuring the stability of the overall structure. The width of the two special-shaped spreader frames 2 is equal to the width of the two mounting holes 10. This design enables the special-shaped spreader frames 2 to better match the mounting holes 10, ensuring the tightness and stability of the installation and improving the reliability of the entire spreader system.

[0030] Working principle: The wooden pallet 1 is the basic component for carrying products. The mounting holes 10 on its left and right sides are the key connection points of the entire sling system. The special-shaped sling frame 2 is one of the core components for realizing the lifting function. Its bottom adopts an arc-shaped corner design. When the special-shaped sling frame 2 is installed in the mounting hole 10 of the wooden pallet 1, the arc-shaped corner can fit well with the bottom contour of the mounting hole 10, ensuring the stability of the sling frame 2 in the horizontal direction and preventing lateral displacement during the lifting process. The Z-shaped structure in the middle of the special-shaped sling frame 2 plays a unique role. During the installation process, the middle part of the Z-shaped structure can be engaged with the side away from the top of the mounting hole 10, and the bottom is engaged with the side adjacent to the bottom of the mounting hole 10. This engaging method enables the special-shaped sling frame 2 to form a stable interlocking structure with the wooden pallet 1. When upward force is applied, the special-shaped sling frame 2 and the wooden pallet 1 are locked. When pulling, due to the tight engagement between the special-shaped spreader frame 2 and the wooden pallet 1, the pulling force can be effectively transmitted to the wooden pallet 1, thereby driving the entire pallet 1 and the products placed thereon to rise together. In actual use, first align the two special-shaped spreader frames 2 with the mounting holes 10 on the left and right sides of the wooden pallet 1, and then insert them. With their special shape and structure, they can be easily and accurately snapped into the corresponding positions. The special-shaped spreader frames 2 are tightly combined with the wooden pallet 1. When the external lifting force is applied to the special-shaped spreader frames 2 through the lifting mechanism, due to the stable connection between the special-shaped spreader frames 2 and the wooden pallet 1, the pallet 1 and the products can be lifted smoothly. During the whole process, the unique structural design of the special-shaped spreader frames 2 ensures the effective transmission of force and the stability of the entire system, so that the products can complete the lifting operation safely and efficiently.

[0031] The tops of the multiple steel ropes 4 are fixedly connected with lock piece 2 5, and lock piece 2 5 plays the role of a bridge connecting the steel rope 4 and the lifting ring 6. Its stable connection ensures that the force can be smoothly transmitted from the steel rope 4 to the lifting ring. The ring 6 is used as the final force application point for the external lifting equipment to hook. When the external lifting equipment lifts the ring 6 upward, the tension is transmitted to the special-shaped spreader frame 2 through the lock 2 5, the wire rope 4, and the lock 1 3 in sequence, and finally the lifting operation of the pallet and the product is realized. In the actual lifting operation, the external equipment hooks the ring 6 and applies an upward pulling force. The pulling force is evenly distributed to each wire rope 4 through the lock 2 5. The wire rope 4 is tightened under the action of the tension. Due to the firm connection between the wire rope 4 and the special-shaped spreader frame 2, the special-shaped spreader frame 2 is subjected to an upward traction force, and its tight engagement structure with the wooden pallet 1 causes the wooden pallet 1 to be lifted up accordingly, ensuring the stability and reliability of the lifting. At the same time, the design of multiple wire ropes 4 helps to disperse the force, improve the safety of the entire lifting system, and prevent component damage or lifting failure due to excessive force on a single point, thereby ensuring that the product can safely and efficiently complete the transportation process from the initial position to the specified position.
