Description

Technical Field

[0001] The invention relates to a U-shaped lifting ring, in particular to a U-shaped lifting ring device suitable for steel wire rope lifting. Background Art

[0002] Wire rope lifting technology is widely used in construction projects, especially in the lifting of components of steel and concrete structures. The combination of wire rope and lifting ring has become a common connection method.

[0003] For example, patent document CN2089561U discloses a wire rope hoisting clamp fastened by a screw. Although it can achieve the connection between the wire rope and the hoisting ring, it has a complex structure and cumbersome installation and disassembly steps, which affects the hoisting efficiency and poses a major safety hazard during high-altitude operations.

[0004] Another example is the quick-connect lifting ring for steel structure lifting introduced in patent document CN109345678A. Although it attempts to simplify the disassembly and assembly process, it still uses a threaded fastening method and relies on manual rotation during disassembly and assembly, making it difficult to achieve safe long-distance operation. There are still operational inconveniences and safety risks.

[0005] According to relevant industry standards such as the "Technical Code for Safety in Construction" (GB50870-2013) and the "Technical Code for Steel Structure Construction" (GB50661-2011), lifting devices must not only ensure a firm and reliable connection, but also be easy to operate and disassemble, so as to effectively reduce the labor intensity and safety risks of workers working at heights.

[0006] However, the traditional screw and bolt fastening methods in the existing technology can achieve the connection between the wire rope and the lifting ring, but the disassembly and assembly process is cumbersome, and disassembly often requires manual close-range operation, which poses a major safety hazard and is low in efficiency, making it difficult to meet the needs of modern construction for fast and safe lifting.

[0007] In the known technology, safety rope assisted disassembly has been generally recognized as an important means to improve lifting safety. However, the lifting device combined with this technology has not yet solved the problems of complex disassembly and assembly and inconvenient operation, and further improvement is urgently needed.

[0008] Therefore, the existing technology still cannot meet the comprehensive requirements of modern construction sites for the safety, simplicity and efficiency of lifting devices. There is an urgent need for a wire rope lifting device with a reasonable structure, easy to plug and unplug, and capable of safe long-distance operation. Summary of the Invention

[0009] The purpose of the present invention is to provide a U-shaped lifting ring device suitable for wire rope lifting.

The front end of the suspension rod is beveled for easy insertion, the rear end is horseshoe-shaped, 3mm thick, 35mm in outer diameter, and the middle hole has a diameter of 5.5mm. The suspension rod is provided with an annular groove near each end, and the annular groove corresponds to the steel ball in the slot, and the steel ball can move into the annular groove; The slotted steel balls are arranged in three sets in each of the two lifting eye holes of the U-shaped lifting eye, and are evenly arranged so as to stabilize the lifting rod in the center of the lifting eye hole; Among them: the suspension rod can be movably connected with the steel ball.

[0017] The present invention will be further described below with reference to the embodiments and the accompanying drawings.

[0018] Example 1 The U-shaped lifting ring device suitable for steel wire rope lifting of the present invention comprises a U-shaped lifting ring, a lifting rod and a slotted steel ball.

[0019] Please refer to Figure 1 , Figure 1 The structure diagram of the lifting device of the embodiment of the present invention is shown in the figure. As shown in the figure, the U-shaped lifting ring 1 has an inner diameter of 85mm-98mm and an outer diameter of 142mm-155mm. The two supporting rods of the U-shaped lifting ring are each provided with a lifting ring hole, and the two lifting ring holes cooperate with each other.

[0020] Figure 2 This is a front view of a U-shaped hanging ring according to an embodiment of the present invention. Figure 3 This is a side view of a U-shaped lifting ring according to an embodiment of the present invention. The lifting rod 2 has a diameter of 24mm-35mm and a total length of 220mm. The front end of the lifting rod is beveled for easy insertion, while the rear end is horseshoe-shaped, 3mm thick, 35mm in outer diameter, and has a central hole with a diameter of 5.5mm. An annular groove is provided near each end of the lifting rod, which corresponds to the steel ball in the slot, allowing the steel ball to move into the annular groove.

[0021] Figure 4 This is a schematic diagram of the structure of the boom according to an embodiment of the present invention. The slotted steel balls 3 are arranged in three sets in each of the two eyelets of the U-shaped hoist ring, evenly spaced to stabilize the boom in the center of the eyelet. Among them: the suspension rod can be movably connected with the steel ball.

[0022] Figure 5 The figure is a schematic diagram of the steel ball structure of the card slot according to an embodiment of the present invention. In the card slot, one end of the steel ball extends out of the card slot, and the other end of the steel ball is connected to the spring, and the tail end of the spring is provided with a blocking screw.

[0023] Installation and use instructions of the U-shaped lifting ring device for mixed use with steel wire rope lifting of the present invention: (1) When using, first put the binding wire rope into the U-shaped lifting ring; (2) Insert the lifting rod into the holes on both sides of the lifting ring; (3) When the boom is inserted into the groove and the steel ball in the slot is aligned, it is installed in place and the lifting conditions are met; (4) When the wire rope needs to be untied after use, just pull out the boom. If it is inconvenient to pull it out manually, you can pull it out by dragging the safety rope through the hole at the end of the boom.

[0024] The present invention has substantial features and significant technological advancements. Compared to conventional methods of suspending and untying wire ropes via screws, the U-shaped hoist ring device of the present invention can be directly plugged in and out, eliminating the need for tedious tightening and loosening screws. Furthermore, the device is reliable in use. During steel structure hoisting, the U-shaped clasp and wire rope are first securely fastened. Once the steel structure is in place, workers can directly untie the wire rope from the ground by pulling the pin of the U-shaped clasp with a safety rope. This eliminates the need for workers to reach heights to untie the wire rope, reducing the risks of high-altitude work. This improves material lifting efficiency and achieves twice the result with half the effort.

[0025] The above embodiments are intended to illustrate the present invention only and are not intended to limit the present invention. Persons skilled in the art may make various modifications or variations without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions are intended to fall within the scope of the present invention and are defined by the claims.
