Description

Technical Field

[0001] The utility model belongs to the technical field of profile production, and in particular relates to a steel dismantling lifting device. Background Art

[0002] In order to save floor space, finished products such as electric angle steels and marine bulb flat steels are usually stored in stacks. Before stacking or transporting profile products, it is sometimes necessary to flip the products to a suitable state (for example, the electric angle steel was originally placed on the ground in an L-shaped state, and now it needs to be flipped to an inverted V-shaped state for easy stacking, that is, the open side is facing down). At present, the products are often wrapped with slings, then lifted by lifting equipment, and finally turned over by manual and equipment collaboration, which is difficult to operate and has poor safety. Before the stacked products are shipped and sold, tools such as crowbars are needed to split the stacked products, and then ship them by piece. However, due to the large weight of a single profile product, manual disassembly is not only difficult to operate, time-consuming and labor-intensive, but also poses a great safety risk. Therefore, it is urgently needed to provide a steel disassembly sling to reduce the difficulty of product disassembly and flipping, reduce production risks, and improve operating efficiency.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] In the description of the present invention, it should be understood that the terms "middle", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0022] In the present invention, unless otherwise clearly specified and limited, the terms "set", "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] like Figures 1 to 3 As shown, a steel disassembly lifting device includes a sling 1, a hanging rod 2, a base 4 and two hooks 8. The sling is connected to the hanging rod, and the hanging rod is connected to the base. A lifting ring 7 is hinged on the upper end of each hook. The lifting ring and the hook are assembled and connected by bolts. The lifting ring can rotate freely along the bolts, which is convenient for disassembly, replacement and maintenance. Each lifting ring is connected to the lower end of the base by a lifting rope 6. A hook 3 that cooperates with the lifting ring is provided on one side of the hanging rod. The end of the hook is a wedge-shaped structure, which is convenient for quick insertion into the gap between two adjacent stacked products. When in use, connect the sling to the lifting equipment, and use the two together. Determine the number of hooks required according to actual needs. If the utility model needs to be used for dismantling operations, insert the two hooks into the gaps on both sides of the stacked products respectively, connect the sling to the lifting equipment, and use the two hooks to drive the upper product to separate from the lower product, thereby realizing the dismantling function. If the utility model needs to be used for steel turning operations, hang the lifting ring of one of the hooks in the hook, and hook the other hook on the bottom of the product, and realize the product steel turning operation under the action of the lifting equipment.

[0024] like Figures 1 to 3 As shown, a strip slide 401 is provided on the base along its length direction, and two slide bars 402 are slidably connected in the strip slide, and a fastening nut 403 is threadedly connected at the end of each slide bar for fixing its position. The two lifting ropes are respectively connected to the two slide bars one by one. By adjusting the position of the slide bar in the slide groove, the position of the hook and the distance between the two hooks can be adjusted. The slide bar can adopt a bolt structure, and a nut is used to lock and fix it at its end. At least three grooves 404 are evenly distributed on the bottom wall of each strip slide groove, and the inner diameter of the groove matches the outer diameter of the slide bar. Embedding the slide bar in the groove can enhance the stability of its connection structure, avoid displacement during lifting, and improve operation safety. The vertical cross-section of the base is an inverted U-shaped structure, and the number of strip slide grooves is two. The two strip slide grooves are symmetrically distributed on both sides of the base, which is convenient for the sliding and fastening of the slide bar. The symmetrically designed strip slide grooves can provide stable support for the slide bar and also facilitate the connection of the suspension rope and the slide bar.

[0025] A rotating shaft mechanism 5 is provided between the suspension rope and the slide rod, and the rotating shaft mechanism includes a base 501 and a rotating shaft 502. The rotating shaft and the base are rotatably connected by a bearing. One end of the rotating shaft is connected to the suspension rope, and the other end is rotatably connected to the base. The base is connected to the slide rod to avoid obstruction in the twisting process of the suspension rope and inconvenience in use.

[0026] The method of using the utility model is as follows (taking the electric angle steel product as an example):

[0027] (1) If Figure 4 As shown, the power angle steel products are stacked and placed, and the end of the hook 8 is inserted into the gap between two adjacent angle steels. The two hooks are symmetrically arranged, and the hooks are lifted by a lifting device, so as to separate the corresponding product from the product below it, so as to achieve the purpose of disassembly;

[0028] (2) If Figure 5 As shown, when the product is placed in an L-shaped state, one of the hooks is extended into the bottom of the product and hooked, and then the product is lifted by the lifting equipment, which can realize the automatic flipping of the product and achieve the purpose of turning the steel.
