Description

Technical Field

[0001] The present application belongs to the technical field of lifting slings, and specifically relates to a stable lifting sling. Background Art

[0002] A sling refers to a device used to lift heavy objects in a lifting machinery. It is widely used in the lifting and hoisting industry. Commonly used lifting slings include chain slings such as hooks and rings, as well as special slings with special lifting interfaces such as suction cups and clamps. In order to control the stability of the sling, the sling is usually equipped with some devices to cooperate with the crane, or a stabilization system is added to the body. In recent years, the application of lifting slings in various fields has become increasingly widespread, greatly improving the effectiveness of operations. With the continuous development of technology, more attention has been paid to the safety, stability and reliability of lifting slings. While improving the effectiveness of product production, the stability and reliability of the product should be optimized.

[0003] As disclosed in the application with publication number CN216836744U, the utility model discloses a sling with stable transportation, which relates to the field of slings. A sling with stable transportation includes a base, a support rod is arranged on the top of the base, a fixed block is welded on the top of the support rod, a top beam is fixedly connected to the inner side of the fixed block, a slide groove is provided through the front of the top beam, and two damping mechanisms are fixedly connected inside the slide groove. The utility model causes the threaded rod to shake through the lifting chain by the shaking of the cargo, the threaded rod drives the bearing to shake, the bearing drives the fixed plate to slide, the fixed plate drives the stabilizing rod to shake, and at the same time, the spring is compressed and stretched under the action of the stabilizing rod, and the shaking amplitude of the cargo can be reduced under the action of the damping mechanism and the cargo shaking at the same time, which is beneficial to the lifting work of the cargo and improves the lifting work efficiency.

[0004] However, common lifting slings use claws or suction cups to grab objects and move them upward, which makes the objects shake easily, and the contact surface between the sling and the object is small, so the stability of the sling is poor. Lifting slings with more complex structures are more difficult to install and maintain, and the technical and material costs are relatively high. Utility Model Content

When in use, the user pulls the telescopic claw 5 outward until the adsorption metal block 12 is embedded in the adsorption magnetic block 13, and the ends of the lifting device's arms 2 can be connected in pairs, and the adsorption metal block 12 and the adsorption magnetic block 13 are tightly attracted and not easy to fall off. After the user places the object, the contact area between the object and the lifting device is increased, and the stability of the lifting device during lifting is increased.

[0031] The upper surface edge of the load-bearing plate 1 is fixedly mounted with a hanging card plate 3. The hook on the sling can hook the groove of the hanging card plate 3, thereby enhancing the stability of the sling.

[0032] A buckle reinforcement member 9 is welded to the upper surface of the load-bearing plate 1. The contact area of ​​the buckle 10 is too small, and increasing the contact area between the buckle 10 and the load-bearing plate 1 improves safety.

[0033] The upper surface of the buckle reinforcement member 9 is fixedly connected with a buckle 10. It is convenient for the user to lift the sling with a hook.

[0034] The inner part of the spring retractor 4 is fixedly installed with a limiting rod 14, and the limiting rod 14 is welded with a limiting cross bar 17 near one side of the telescopic hanging claw 5. To prevent the spring 15 from falling off during use, the limiting cross bar 17 plays a limiting role.

[0035] One side of the telescopic hanging claw 5 is fixedly connected with a hand push handle 7. It is convenient for the user to pull the spring 15 through the hand push handle 7.

[0036] The upper surfaces of the telescopic lifting claw 5 and the connecting lifting claw 6 are provided with a steel bar groove 11. The steel bar groove 11 or the cylindrical object is not easy to move or slide during the lifting.

[0037] The implementation principle of a stable lifting sling embodiment of the present application is as follows: the user holds the push handle 7 and pulls the telescopic claw 5 outward until the adsorption metal block 12 is embedded in the adsorption magnetic block 13. At this time, the ends of the sling arms 2 are connected in pairs, which increases the contact area between the lifting sling and the object and enhances stability. Since the adsorption metal block 12 and the adsorption magnetic block 13 can be tightly attracted and not easily fall off, the safety and reliability of the lifting sling are also enhanced. Providing a steel bar groove 11 on the upper surface of the telescopic claw 5 and the connecting claw 6 can prevent steel bars or cylindrical objects from moving or falling during the lifting process.
