Description

Technical Field

[0001] This invention relates to the field of lifting sling manufacturing technology, and more specifically, to an integrated processing equipment for spiral winding and twisting of a circular lifting sling bearing core. Background Technology

[0002] In the hoisting of large components, ring slings are widely used. These slings typically consist of an outer abrasion-resistant belt and an inner high-strength fiber core. However, the production of large-tonnage slings, such as 100T cores, still mainly relies on manual winding, which exposes several technical problems.

[0003] First, manual operation makes it difficult to ensure that the yarn is evenly and tightly arranged during the winding process, often resulting in uneven yarn distribution. This leads to uneven yarn distribution under stress, low material utilization (typically only 70%-80%), and significant waste of high-strength yarn. Second, due to the significant impact of human factors, the product quality stability is poor, and the consistency of the load-bearing core between different batches, and even within the same batch, is difficult to guarantee, posing a safety hazard. Third, the current production method is inefficient. Taking a 100-ton, 20-meter-long sling as an example, the core winding process alone requires three workers and 1.6 hours to complete, and the subsequent leather-on sewing requires another three workers and 1.5 hours. The overall process is complex, the production cycle is long, and labor costs remain high.

[0004] Currently, there is a lack of dedicated automated equipment suitable for the production of large-tonnage, long-length bearing cores. Existing small horizontal core-threading machines cannot meet the integrated production needs of bearing cores longer than five meters in terms of twisting, spiral winding, and automatic tape application. There is an urgent need to develop more advanced equipment to improve manufacturing capabilities. Summary of the Invention

[0049] Compared with the prior art, the beneficial effects of the present invention are:

[0050] This invention relates to an integrated spiral winding and twisting processing device for a circular ring-shaped sling bearing core. The bearing core is sequentially wound around an upper drive wheel, a driven wheel, and a lower drive wheel to form a triangular ring structure. A wheel drive assembly drives the upper and lower drive wheels to rotate, thereby rotating the bearing core. Multiple yarn spindles are mounted on a rotating pallet. A turntable drive assembly drives the turntable pallet to rotate, causing the yarn spindles to revolve, resulting in multiple yarns spirally winding around the outside of the bearing core. Through the combined motion of cyclic winding and revolving twisting, the yarns are spirally, neatly, and uniformly arranged, resulting in high consistency of yarn stress and saving 10%–20% of yarn consumption. Mechanized and standardized production effectively eliminates human variations, making the bearing core compact and dense, effectively suppressing relaxation diffusion after single-filament breakage, and significantly improving overall stress performance.

[0051] The integrated spiral winding and twisting processing equipment for the circular sling support core of this invention is equipped with a belt installation device. Before making the support core, a belt is pre-attached to a belt sleeve. When the support core reaches the preset number of windings, the machine stops, and a worker manually attaches one end of the belt pre-attached to the support core. The machine is then restarted, and the belt is driven to gradually and completely wrap the support core along the circulation direction by the friction between the support core and the belt. During this process, the belt sleeve is removed, and the belt is manually sewn to form a closed-loop sling. This invention integrates the winding and belt attaching processes, achieving integrated production. The automated equipment replaces the heavy manual labor of repeated pulling, winding, and sewing. Compared to a fully manual method, it is expected to save 5 operators and increase production efficiency by more than 54%.

[0052] The integrated processing equipment for spiral winding and twisting of the circular sling bearing core in this invention can flexibly produce circular slings of different specifications ranging from 5 to 20 meters by adjusting the position of the tension trolley, the length of the track, and the height of the lifting support.

[0093] The method for manufacturing a circular sling using the integrated spiral winding and twisting processing equipment for the circular sling bearing core 4 in this embodiment includes the following steps:

[0094] Feeding and threading steps: Place the yarn spindle material 231 on the twisting device 23. The yarn is gathered by the yarn guiding component and passes through the upper drive wheel 221, the pre-fitted sheathed sleeve 52, the driven wheel 32 on the tensioning trolley 3, the bottom drag wheel group 6, and the lower drive wheel 222 in sequence, and finally closes to form a triangular circulating yarn loop.

[0095] Tensioning step: The drive cylinder 35 of the tensioning trolley 3 pulls the slide 34 and driven wheel 32 to move, tensioning the material yarn loop to the set tension;

[0096] Spiral winding and twisting steps: Start the main unit 2, the upper drive wheel 221 and the lower drive wheel 222 operate synchronously to drive the material yarn to circulate, and at the same time the twisting device 23 drives the yarn spindle material 231 to revolve, so that the yarn generates spiral twist and is evenly wound during the circulation, forming the carrying core 4.

[0097] Automatic tape wrapping steps: After reaching the preset number of wrapping strands, stop the machine, wrap one end of the tape pre-wrapped on the tape sleeve 52 around the carrier core 4, restart the main machine 2, and rely on the friction between the carrier core 4 and the tape to drive the tape to gradually and completely wrap the carrier core 4. During the process, remove the tape sleeve 52 to make the tape form a closed loop.

[0098] Material feeding step: The drive cylinder 35 of the tensioning trolley 3 pushes the slide 34 and driven wheel 32 to move, relieve the tension, and take out the finished ring sling along the notch of the twisting device 23.
