Abstract
Description
Technical Field
[0001] The present application relates to the field of aircraft assembly technology, and further to the lifting technology of aircraft parts, and specifically to a product lifting point conversion device and a method of use. Background Art
[0002] The aircraft assembly line is the assembly line of the aircraft in the manufacturing process. Each production line is composed of different stations. In the process of product production and circulation, it is necessary to move from one station to the next, and some auxiliary equipment is needed to complete these operations. These auxiliary equipment are what we call hanging. The safe and reliable loading and unloading of products and large parts is not only related to the quality of the products, but also a kind of protection for the construction personnel. Especially with the rapid development of aviation products, the structural dimensions of the products are large, the number of parts is large, and the complexity is high. Considering the safety and efficiency of lifting, it is difficult to guarantee it only by ordinary slings. At present, the traditional lifting method is to pass the sling directly through the round hole reserved in the product design at one end, and connect the product to the other end. This method is relatively simple to use, but the direct connection of the sling to the product makes it easy for the gravity load of the product to act directly on the product during the lifting process, and the force is uneven at this point, which can easily cause the product to deform or even be damaged during lifting, affecting the efficiency of subsequent transfer stations, thereby extending the delivery cycle of the aircraft. Therefore, a method suitable for point conversion during product lifting is needed to complete the product lifting point transfer work and ensure that the product lifting point is evenly stressed. Summary of the invention
[0003] In order to solve the above problems, the purpose of the present application is to provide a product lifting point conversion device and a method of use.
[0004] A product lifting point conversion device is characterized in that the main body of the conversion device is a double-layer cone structure, the diameter of the upper cone is smaller than that of the lower cone, the diameter of the upper cone is smaller than the lifting hole on the product, and the diameter of the lower cone is larger than the lifting hole on the product. There is a protruding double-ear joint at the top center of the upper cone, the two ears are connected by a transverse axis, the center of the transverse axis is connected to a sling, and at the top center of the upper cone, there is a central through hole that penetrates the double-layer cone structure between the two ears, and there is a fixing buckle matching the double-layer cone, the fixing buckle is a buckle plate with both ends bent downward, and there is a connecting hole in the middle of the fixing buckle that matches the central through hole of the double-layer cone structure, the distance between the two end heads of the fixing buckle is greater than the diameter of the upper cone and smaller than the diameter of the lower cone, and there is a tightening bolt that connects the fixing buckle and the double-layer cone structure through the central through hole and the connecting hole.
[0005] The method for using the above-mentioned product lifting point conversion device is characterized in that it includes the following contents: 1) Determine the lifting hole position of the product, select the product lifting point conversion device that matches the lifting hole, decompose the sling and the fixing buckle from the double-layer truncated cone structure, push the upper truncated cone upward from the bottom of the lifting hole of the product into the lifting hole, so that the lower truncated cone fits the lower surface of the lifting hole; 2) Put the annular end of the sling into the middle of the double-ear joint, so that the horizontal axis can pass through the annular end of the sling and connect and fix it with the double-ear joint; 3) Press the fixing buckle between the double-ear joints, and crimp the two ends of the fixing buckle to the upper surface of the product on both sides of the product lifting hole. Use a tightening bolt to pass through the center through hole and the connecting hole of the fixing buckle from the lower surface of the lower truncated cone upward, and tighten the nut of the tightening bolt so that the lower truncated cone fits tightly with the lower surface of the product around the product lifting hole;
[0006] 4) Finally, check whether the sling is broken, check whether the connecting bolts of the horizontal axis of the product lifting point conversion device and the tensioning bolts between the fixing buckle and the double-layer frustum structure are tightened, and lift the product after confirming that everything is correct.
[0007] The beneficial effects of the present application are: 1) The product lifting point conversion device increases the force-bearing area of the product lifting point, ensuring that when the product is lifted, the parts will not be overloaded due to the weight of the product and thus deformed or damaged, making the force on the product more uniform when lifted. At the same time, by using the lifting device, the tilt of the product caused by the hanging or the center of gravity shift of the product can be avoided, ensuring the stability of the product during unloading or transfer. 2) The present application has the advantages of simple structure and easy use. It can be used not only for lifting aircraft parts, but also for lifting product parts in other industrial production.

[0012] Referring to the accompanying drawings, the main body of the product lifting point conversion device of the present application is a double-layer truncated cone structure, which forms the bottom tray when the product is hung, and its upper truncated cone 2 has a smaller diameter than the lower truncated cone 1. The upper truncated cone 2 and the lower truncated cone 1 in the embodiment are an integrated circular step structure, the outer diameter of the upper truncated cone 2 is smaller than the lifting hole 9 on the product 8, and the diameter of the lower truncated cone 1 is larger than the lifting hole 9 on the product. There is a protruding double-ear joint 3 at the top center of the upper truncated cone 2. In implementation, the double-ear joint 3 and the circular step structure are preferably an integrated machine-added structure, and the two ears are connected by a horizontal axis 4, and the center of the horizontal axis is connected to the sling 7. When the sling 7 is connected to the horizontal axis, the end of the sling is preferably wrapped around the horizontal axis between the two ears, and the end of the sling can be kept rotating between the double-ear joints, so that the sling remains perpendicular to the horizontal axis when subjected to force. At the top center of the upper frustum 2, there is a central through hole that penetrates the double-layer frustum structure between the two ears, and there is a fixing buckle 5 that matches the double-layer frustum. The fixing buckle 5 is a buckle plate with both ends bent downward. There is a connecting hole in the middle of the fixing buckle 5 that matches the central through hole of the double-layer frustum structure. The distance between the two end heads of the fixing buckle 5 is greater than the diameter of the upper frustum 2 and smaller than the diameter of the lower frustum 1. The width of the fixing buckle 5 is smaller than the gap between the two ears, and there is a tightening bolt 6 that connects the fixing buckle 5 and the double-layer frustum structure through the central through hole and the connecting hole.
[0013] When using the above-mentioned product lifting point conversion device to hang the product 8, first determine the position of the lifting hole 9 of the product 8, select the product lifting point conversion device that matches the lifting hole 9, decompose the sling 7 and the fixing buckle 5 from the double-layer round table structure, push the upper round table 2 upward from the bottom of the lifting hole 9 of the product 8 into the lifting hole 9, so that the lower round table 1 fits on the lower surface of the lifting hole 9; then, Put the annular end of the double-ear joint 3 into the middle of the double-ear joint 3, so that the horizontal axis 4 can pass through the annular end of the sling 7 and be connected and fixed to the double-ear joint 3; then buckle the fixing buckle 5 between the double-ear joints 3, and crimp the two ends of the fixing buckle 5 to the upper surface of the product 8 on both sides of the product lifting hole 9. Use the tightening bolt 6 to pass through the central through hole and the connecting hole of the fixing buckle 5 from the lower surface of the lower truncated table 1 upward, and tighten the nut of the tightening bolt 6 to make the lower surface of the lower truncated table 1 and the product 8 around the lifting hole 9 of the product fit tightly; finally, check whether the sling 7 is broken, check whether the connecting bolt of the horizontal axis 4 of the product lifting point conversion device and the tightening bolt 6 between the fixing buckle 5 and the double-layer truncated table structure are tightened, and lift the product after confirmation.
