Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to an anti-swaying, convenient and efficient lifting device for cranes. Background Art

[0002] In the field of lifting machinery, spreaders are key components whose performance directly impacts the safety, efficiency, and stability of lifting operations. Traditional spreaders often experience unavoidable workpiece wobble during the lifting process, especially when handling heavy, large, or irregularly shaped workpieces. This wobble not only increases operational difficulty and reduces efficiency, but can also cause damage to on-site personnel, equipment, and the workpiece itself, posing a serious safety hazard.

[0003] The shaking of workpieces mainly comes from multiple aspects: first, natural environmental factors such as wind will affect the workpiece during hoisting, causing it to deviate from the predetermined trajectory; second, during the lifting and speed change of the crane, mechanical inertia and system response delay may also cause the workpiece to shake; in addition, factors such as the weight, shape, and center of gravity distribution of the workpiece itself will also affect the stability of the hoisting.

[0004] To address this issue, researchers and technicians both domestically and internationally have conducted extensive research and practice. However, existing anti-sway technologies often suffer from complex structures, high costs, and poor applicability, hindering their effective application in a wide range of industrial fields. Therefore, developing a simple, cost-effective, and adaptable anti-sway spreader for cranes that is convenient and efficient is crucial for improving the safety, efficiency, and stability of lifting operations. Utility Model Content

[0005] The purpose of the utility model is to provide a convenient and efficient anti-sway lifting device for cranes, so as to solve the problem that the existing lifting devices are prone to workpiece shaking when lifting heavy, large or irregularly shaped workpieces.

[0006] The technical solution of the utility model to solve the above technical problems is as follows:

[0007] A convenient and efficient anti-sway lifting device for a crane, comprising: a lifting frame, a plurality of anti-sway components arranged at the bottom of the lifting frame, and a top of the lifting frame connected to the crane;

[0008] The anti-sway assembly includes a connecting rod symmetrically arranged at the bottom of the lifting frame and a sliding sleeve fixed to the inner end of the connecting rod. The top and bottom of the sliding sleeve are respectively provided with limit springs, and a limit rod is provided inside the limit spring. The sliding sleeve is provided on the limit rod, and the top of the limit rod is provided with a top baffle for limiting the limit spring. The bottom of the limit rod is connected to the lifting plate.

[0009] Preferably, a bottom fixing ring is fixed to the bottom of the hanging plate.

[0010] Preferably, a bottom hanging ring is sleeved on the bottom fixing ring, and the bottom hanging ring is provided with circular rings that are locked with each other.

[0011] Preferably, a hook is provided on the bottommost circular ring, and the hook hooks the workpiece to be hoisted.

[0012] Preferably, a hanging column is welded to the top of the hanging frame, and a top fixing ring is fixed to the top of the hanging column.

[0013] Preferably, the top fixing ring is provided with interlocking rings, and the topmost ring is provided with a top hanging ring.

[0014] The utility model has the following beneficial effects:

[0015] Improved operational safety: The anti-sway component design significantly reduces the swaying of the workpiece during lifting, lowering potential safety hazards caused by swaying, such as the risk of workpiece falling off and collision, thereby improving the safety of the work site.

[0016] Improve work efficiency: During the lifting process, multiple demoulding and lifting operations can be achieved at one time, reducing the time wasted due to lifting only one workpiece at a time, thereby improving the overall work efficiency.

[0017] Enhanced equipment durability: Long-term shaking can cause damage to lifting equipment and workpieces, such as wear and cracks. By reducing shaking, the probability of damage is reduced, the service life of equipment and workpieces is extended, and maintenance and replacement costs are reduced.

[0018] Strong adaptability: The sling is designed to be flexible. By adjusting the number and layout of anti-sway components, it can adapt to the lifting needs of workpieces of different weights, shapes and sizes, improving the versatility and adaptability of the equipment.

[0019] Reduce energy consumption: Reducing workpiece shaking also means reducing the useless work done by the crane to overcome shaking during the lifting process, thereby reducing energy consumption, which is beneficial to energy conservation, emission reduction and environmental protection.

[0020] Improve user experience: For operators, using this spreader can complete lifting tasks more easily and accurately, reducing work intensity and pressure, and improving work satisfaction and user experience. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0025] Please refer to Figure 1-2 The present invention provides a convenient and efficient anti-sway sling for cranes, which is mainly composed of a hoisting frame 1 and a plurality of anti-sway components 2. The hoisting frame 1 serves as the main frame of the entire sling, and a hoisting column 4 is fixed to the top of the hoisting frame 1 by welding or other firm connection methods. A top fixing ring 41 is installed on the top of the hoisting column 4. A series of interlocking rings 5 ​​are designed on the top fixing ring 41. These rings are tightly connected in a nested manner. A top lifting ring 42 is provided on the top ring for connecting to the hook of the crane to realize the lifting operation of the entire sling.

[0026] Setting of connecting rod and sliding sleeve:

[0027] Multiple sets of anti-sway components 2 are symmetrically arranged at the bottom of the hoisting frame 1. Each set includes two connecting rods 21, fixed to either side of the bottom of the hoisting frame 1, forming a stable support structure. Sliding sleeves 22 are fixed to the inner ends of the connecting rods 21. The design of the sliding sleeves 22 allows them to slide within a certain range along the axial direction of the limit rods 24, accommodating the subtle adjustments required under different hoisting conditions.

[0028] The function of limit spring and limit rod:

[0029] Limit springs 23 are installed at the top and bottom of the sliding sleeve 22, providing both cushioning and limiting action. A limit rod 24 is inserted within the limit springs 23, and the sliding sleeve 22 is fitted over the limit rod 24, ensuring stable sliding of the sliding sleeve 22 on the limit rod 24. A top baffle 25 is located at the top of the limit rod 24, limiting the upward movement of the limit springs 23 and providing additional support. The bottom of the limit rod 24 is connected to a lifting plate 26. As the component that directly supports the workpiece, the stability of the lifting plate 26 directly impacts the safety of the lifting operation.

[0030] Connection between bottom fixing ring and lifting ring:

[0031] A bottom fixing ring 27 is fixed to the bottom of the lifting plate 26, which is used to mount a bottom lifting ring 28. The bottom lifting ring 28 is also designed with interlocking rings 5. The nested structure of these rings 5 ​​enhances the strength and stability of the lifting ring 28. A hook 3 is provided on the bottommost ring to hook onto the workpiece to be lifted (not shown), ensuring a secure connection during the lifting process.

[0032] How it works

[0033] During lifting operations, when the crane hoists the entire sling via the top lifting ring 42, the limit springs 23 in the multiple anti-sway assemblies 2 automatically adjust their compression based on the weight and sway of the workpiece. The sliding sleeve 22 slides along the limit rod 24, and the buffering effect of the limit springs effectively absorbs and disperses the sway energy generated by the workpiece during lifting, thereby maintaining the relative stability of the workpiece. Furthermore, the secure connection between the bottom lifting ring 28 and the hook 3 further ensures the safety of the workpiece during lifting.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
