Description

Technical Field

[0001] The utility model relates to a balance beam sling with adjustable force distribution and multiple sling points for large-tonnage products, belonging to the technical field of large-tonnage product slinging. Background Art

[0002] The lifting of large-tonnage products is often carried out using a balance beam hoist. The lifting function affects the loading and unloading efficiency, and is also related to the personal safety of the operator, avoiding accidents caused by the tilting of heavy objects during the lifting process.

[0003] Balance beam slings often use multi-point vertical lifting. During the lifting process, due to reasons such as processing accuracy, load deformation, product center of gravity offset, etc., the lifting forces of multiple lifting points are often different, and the difference is even very large, forming torque on the product, sometimes causing irreversible damage to the product or the product's lifting points. In severe cases, the sling fails and the product falls.

[0004] At present, there is no better and easy-to-operate lifting device with visual and adjustable lifting point force. Therefore, a balanced beam lifting device is proposed to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problems of the existing slings for large-tonnage products, such as the difficulty in balancing and adjusting multiple sling points and the inconvenience in operation, and to provide a balancing beam sling with adjustable multiple sling points for large-tonnage products.

[0006] The purpose of this utility model is achieved through the following technical solutions:

[0007] The utility model discloses a balance beam sling with adjustable force distribution at multiple lifting points for large-tonnage products, comprising a balance beam, four sets of lifting chain assemblies arranged at both ends of the balance beam,

[0008] The balance beam is composed of a horizontal beam and horizontal longitudinal beams vertically fixing the two ends of the horizontal beam, and a set of suspension chain components are respectively arranged at the two ends of each horizontal longitudinal beam.

[0009] Each set of lifting chain assemblies includes a lifting chain extending from the end of the horizontal longitudinal beam, a hook arranged at the lower end of the lifting chain, a tension sensor and a lifting chain length adjuster arranged in the middle of the lifting chain, and a sensor display arranged at the end of the horizontal longitudinal beam; the tension sensor is connected to the sensor display via a data cable, and the tension sensor transmits the tension value of the lifting chain to the sensor display in real time.

[0010] Working process

[0011] When lifting large-tonnage products, first connect the four hooks of the balance beam sling to the various lifting points of the large-tonnage products respectively; then lift the balance beam sling vertically through the lifting equipment; observe the tension values ​​of each sensor display during the lifting process, and adjust the length of the lifting chain corresponding to each lifting point through the lifting chain length adjuster according to the different tension values ​​corresponding to different lifting points, until the tension values ​​of each sensor display are consistent, and then completely lift the large-tonnage product off the ground.

[0012] Beneficial effects of the utility model:

[0013] Compared with conventional slings, this sling has the following beneficial effects:

[0014] 1. By adjusting the lifting force of each lifting point, it is ensured that the force on each lifting point is uniform during the lifting process, which greatly reduces the torque on large-tonnage products and ensures the lifting quality.

[0015] 2. Through the visualization of the force distribution of the lifting points and the adjustable chain length and other functions, the convenience of the lifting equipment operation is greatly improved, and the lifting process can be completed quickly with fewer operators.

[0016] 3. Wide range of applications. This visual structure of lifting point force distribution can be applied to various lifting equipment. It is not limited to balance beam lifting equipment and the number of lifting points. It can be widely used in the lifting of similar products.

[0017] 4. Low cost control, fewer parts and low processing difficulty, and low mass production cost. BRIEF DESCRIPTION OF THE DRAWINGS
