However, these exemplary embodiments may be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.

[0030] In the field of industrial production and logistics, overhead cranes, as an efficient lifting equipment, play an indispensable role. They are widely used in various heavy lifting operations and are key technical equipment for improving production efficiency and ensuring operation safety. The performance and reliability of one of the core components of the overhead crane, the crane hoist, are directly related to the safety and operating efficiency of the entire lifting system. At present, most of the common crane hoists on the market adopt an integrated design. Although this design mode simplifies the manufacturing process to a certain extent, it has many disadvantages, which seriously affects the maintainability and economy of the crane hoist.

[0031] After long-term use, once the traditional integrated anti-drop buckle is damaged, it is difficult to perform partial repair or replacement. Due to the integrated structure, the damage of a small component may cause the entire hook to fail to function, affecting the safety and normal use of the overhead crane hoist. The existing connection between the sling and the parent ring is non-detachable. When these connecting parts or a small part in the connecting component is damaged, the entire overhead crane hoist can only be scrapped because it cannot be disassembled and replaced, which greatly increases the operating cost and also causes a waste of resources.

[0032] In order to solve these problems, the industry urgently needs a new type of detachable crane hoist design. This design can not only improve the maintenance convenience of the crane hoist, but also effectively reduce the operating costs of the enterprise, which is of great significance to promoting the sustainable development of the industry.

[0033] The design concept of the detachable crane hoist comes from a deep understanding of the shortcomings of the existing integrated crane hoist and the need for improvement. The design concept emphasizes modularization and standardization, so that the various components of the crane hoist can be freely combined and disassembled like building blocks. This design is not only convenient for daily maintenance, but also allows for quick replacement of components when they are damaged, greatly reducing downtime and maintenance costs.

[0034] The emergence of detachable crane hoisting equipment provides an effective solution to the problems existing in traditional integrated crane hoisting equipment. It can not only improve the maintainability and economy of crane hoisting equipment, but also promote the technological progress and innovative development of the entire industry. In the future, with the application of more new materials and new technologies and the continuous innovation and improvement of design concepts, it is believed that detachable crane hoisting equipment will be widely used and developed in more fields.

[0035] Combination Figure 1As shown, according to a specific embodiment of the present application, there is provided an overhead crane hoist, comprising: a lifting eye component, the lifting eye component being used to connect a lifting device; at least one first shackle 3, at least one first shackle 3 being detachably connected to the lifting eye component; at least one annular sling 4, one end of a first shackle 3 being relatively far away from the lifting eye component being detachably connected to at least one annular sling 4, and one end of the annular sling 4 being relatively far away from the first shackle 3 being detachably connected to a hook 6.

[0036] In this embodiment, the lifting ring component is a key part for connecting the lifting equipment, and it needs to have sufficient strength and stability to ensure that it can withstand heavy loads during the entire lifting process. At least one first shackle is detachably connected to the lifting ring component. This design allows the overhead crane hoist to be flexibly adjusted in different situations to adapt to different lifting requirements.

[0037] The design of the ring sling enables it to evenly distribute the load and reduce the wear caused by concentrated force. One end of the ring sling is detachably connected to the end of the first shackle away from the lifting ring component, and the other end is detachably connected to the hook. This design not only improves the versatility of the overhead crane hoist, but also facilitates the rapid replacement of damaged parts.

[0038] Traditional sling protective covers are prone to unraveling at the sewing point, affecting use. In order to solve this problem, a new ring sling design was proposed. This design adopts a safe and reliable connection method, which is quick and convenient to install, reliable in connection, and low in cost. This innovative design not only solves the shortcomings of the existing technology, but also improves the overall performance of the overhead crane hoist.

[0039] The connection method between the lifting belt and the lifting hook is also an important consideration. The fiber lifting belt is divided into two types: ring and two-end buckle, usually connected by a combination of lifting butterfly buckle and shackle. This connection method ensures the stability and safety of the lifting process.

[0040] In one embodiment of the present application, the overhead crane hoist also includes: a second shackle 5, an end of an annular sling 4 relatively far away from the first shackle 3, and is detachably connected to the second shackle 5, and an end of the second shackle 5 relatively far away from the annular sling 4 is detachably connected to the hook 6.

[0041] In this embodiment, a second shackle is also included. The shackle is located between the annular sling and the hook, so that the hook can be adjusted according to actual needs, thereby increasing the flexibility and accuracy of the lifting process.

[0042] In one embodiment of the present application, the total number of the endless slings 4 is the same as the number of the second shackles 5 .

[0043] In this embodiment, the annular sling 4 and the second shackle 5 are installed in a one-to-one correspondence.

[0044] In one embodiment of the present application, the total number of the second shackles 5 is the same as the number of the hooks 6 .

[0045] In this embodiment, the second shackle 5 and the hook 6 are installed in a one-to-one correspondence.

[0046] In one embodiment of the present application, the lifting ring component includes: a first lifting ring 1 for connecting a lifting device, at least two second lifting rings 2, at least two second lifting rings 2 are movably connected to the first lifting ring 1, and at least one first shackle 3 is relatively far away from one end of an annular sling 4, and is detachably connected to one end of a second lifting ring 2 relatively far away from the first lifting ring 1.

[0047] In this embodiment, the first lifting ring 1 is the core part of the entire lifting ring assembly, and is mainly used to connect the lifting equipment. It is usually made of high-strength steel to ensure that it will not deform or break when subjected to heavy pressure. The design of the first lifting ring must take into account the load-bearing capacity and safety factor to ensure that it can work stably and reliably during the lifting process.

[0048] In order to improve the stability and safety of the hoisting, at least two second hoisting rings 2 are required. These second hoisting rings are movably connected to the first hoisting rings and can be adjusted according to actual needs. The second hoisting rings are also made of high-strength materials and are precisely processed to ensure their stability under various working conditions.

[0049] In one embodiment of the present application, the outer surfaces of the first suspension ring 1 and the second suspension ring 2 are provided with wear-resistant coating materials.

[0050] In this embodiment, by using this coating, the service life and performance of the lifting ring are significantly improved. This article will discuss the types, characteristics and applications of wear-resistant coating materials in lifting rings.

[0051] Metal wear-resistant coatings mainly include alloy coatings such as nickel-chromium alloys and tungsten carbide. These materials have extremely high hardness and wear resistance and are often used in applications that require high wear resistance. Metal wear-resistant coatings are applied to the surface of the substrate through thermal spraying technology to form a solid protective layer.

[0052] In one embodiment of the present application, an anti-wear protective cover is provided on the outer surface of the endless sling 4 .

[0053] In this embodiment, in order to ensure its safety and durability during use, an anti-wear protective cover is specially provided on the outer surface of the endless sling 4. This design not only increases the service life of the endless sling, but also effectively prevents safety hazards caused by wear. This article will introduce in detail the structure of the endless sling, the role of the anti-wear protective cover and its importance.

[0054] In one embodiment of the present application, the anti-wear protective cover is made of polyurethane.

[0055] In this embodiment, polyurethane can be divided into various types such as polyether type, polyester type, polyimide type, polyurea type, etc., each of which has different characteristics and application ranges. Polyurethane materials can be combined by selecting different isocyanates and polyols to produce products with different hardness, ranging from soft elastomers to hard rigid plastics. In addition, by adding various additives and fillers, the performance of polyurethane can be further improved, so that it has better wear resistance, aging resistance and weather resistance.

[0056] In one embodiment of the present application, the first lifting ring 1, the second lifting ring 2, the first shackle 3 and the second shackle 5 are all made of stainless steel.

[0057] In this embodiment, the stainless steel not only has high strength and can withstand heavy loads and impacts, but also has good toughness, which can maintain structural integrity even under extreme conditions and reduce the risk of fracture.

[0058] According to a specific embodiment of the present application, a lifting equipment is provided, including the above-mentioned overhead crane hoist.

[0059] In this embodiment, a bridge crane is a crane that runs across a workshop or warehouse and is mainly used to lift finished goods. The bridge crane has the advantages of compact structure and small footprint, and is suitable for indoor working environments.

[0060] Gantry crane: Similar to bridge crane, but designed for outdoor use, usually in open areas such as ports and cargo yards. Gantry cranes are characterized by their ability to provide larger spans and heights, adapting to the needs of handling heavy materials.

[0061] Tower crane: Commonly seen on construction sites, its structural features are long suspension and high tower, which can be quickly installed and disassembled. Tower cranes have a wide service range and are suitable for the construction needs of high-rise buildings.

[0062] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0063] In addition to the above, it should be noted that "one embodiment", "another embodiment", "embodiment", etc. mentioned in this specification refer to the specific features, structures or characteristics described in conjunction with the embodiment included in at least one embodiment generally described in this application. The same expression appearing in multiple places in the specification does not necessarily refer to the same embodiment. Further, when describing a specific feature, structure or characteristic in conjunction with any embodiment, it is claimed that the realization of such feature, structure or characteristic in conjunction with other embodiments also falls within the scope of the present invention.

[0064] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
