Technical Field

[0001] The present disclosure relates to the technical field of hoisting equipment, and in particular to a hoisting device and a transportation system. Background Art

[0002] In the current industrial development, precision CNC (Computer Numerical Control) machine tools play a core role in industries such as electronic glass processing, which require extremely high precision. These machine tools integrate a variety of precision components, including but not limited to bed, guide rails, hydraulic systems, electrical circuits and integrated control systems, aiming to achieve high-precision and efficient processing of workpieces.

[0003] The CNC machine tool bed structure generally uses a marble platform as the main component. Due to its material characteristics, the marble bed is often heavy and its brittleness is significantly higher than that of the metal bed. This results in even a slight impact or excessive stress concentration during transportation, which may cause cracks in the bed material and even cause local fragmentation or collapse. However, due to the hard and brittle nature of the marble bed material and the difficulty of processing, it is difficult to design and accurately process a special hole structure for effectively dispersing the lifting stress like a metal bed. In addition, traditional lifting equipment such as lifting rings and hooks may cause excessive local stress concentration when used, increasing the risk of damage to the bed, making it difficult to lift machine tools with marble bed structures.

[0004] Therefore, a lifting device is needed to at least solve the above problems. Utility Model Content

[0005] A technical problem to be solved by the present disclosure is: how to solve the problem of difficulty in lifting because the marble bed structure used in the machine tool cannot be machined with lifting holes and is therefore not suitable for traditional lifting equipment.

[0009] In some embodiments, the lifting ring is detachably connected to the second supporting assembly, and the detachable connecting structure between the second supporting assembly and the lifting ring is vertically arranged below the supporting plane.

[0010] In some embodiments, the second support assembly includes a first plate body and a second plate body arranged opposite to each other in a vertical direction, and the side of the first plate body facing away from the second plate body is a support plane; a plurality of support beams are arranged parallel and evenly spaced between the first plate body and the second plate body, and the lifting ring is detachably connected to the support beam.

[0011] In some embodiments, the lifting ring is a U-shaped structure, with a first through hole passing through each of its opposite ends, and a second through hole corresponding to the first through hole passing through the side of the support beam along the width direction, and the width of the support beam is smaller than the distance between the opposite ends of the lifting ring; it also includes: a connecting shaft, which passes through the first through hole and the second through hole in sequence to connect the lifting ring to the support beam.

[0012] In some embodiments, the vertical distance between the two opposite sides of the first plate body and the second plate body is not greater than the depth of the groove at the bottom of the machine tool to be hoisted.

[0014] In some embodiments, the lifting connection portion is annular, and a pair of reinforcing ribs are symmetrically arranged on both sides of the lifting connection portion.

[0015] The embodiment of the present disclosure also provides a transportation system, including the above-mentioned lifting device.

[0016] Through the above technical scheme, the hoisting device provided by the present invention is respectively connected by connecting the two ends of the first support component and the two ends of the second support component to form a stable hoisting frame; after the first support component is hoisted, the second support component can be automatically positioned directly below the first support component in the vertical direction, ensuring that the two can work together and synchronously bear the weight of the machine tool to be hoisted; by providing a supporting plane on the second support component that precisely matches the bottom groove of the machine tool to be hoisted, the second support component can be partially embedded in the groove at the bottom of the machine tool when hoisting is in progress, thereby avoiding the need for additional hoisting hole processing for the machine tool to be hoisted, and realizing stable hoisting operation of the machine tool to be hoisted.

[0028] The following is a further detailed description of the embodiments of the present disclosure in conjunction with the accompanying drawings and examples. The detailed description of the following embodiments and the accompanying drawings are used to exemplarily illustrate the principles of the present disclosure, but cannot be used to limit the scope of the present disclosure.

[0034] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0035] In CNC machine tools, some models use a marble platform as the main part of the bed. Due to the inherent brittleness of marble, even a slight impact or excessive stress concentration may cause cracks inside the bed material. In extreme cases, local fragmentation or collapse may occur. Compared with a metal bed, it is difficult to design and precisely process a marble bed into a special hole structure for effectively dispersing the hoisting stress, which makes it difficult to transport and hoist the CNC machine tool. Therefore, the embodiment of the present disclosure provides a hoisting device that utilizes the existing groove design at the bottom of the CNC machine tool, thereby achieving stable and safe hoisting operations without any additional processing of the CNC machine tool bed.

[0036] Example 1

[0037] The present disclosure provides a lifting device, such as Figures 1 to 5As shown, it includes: a first support assembly 1, which is arranged in the horizontal direction, and a lifting connection part 101 for cooperating with the lifting equipment is provided in the middle of the first support assembly 1; and a second support assembly 2, which is arranged in the same direction as the first support assembly 1, and the two ends of the second support assembly 2 are respectively connected to the two ends of the first support assembly 1. When the first support assembly 1 is lifted away from the ground through the lifting connection part 101, the second support assembly 2 is located directly below the first support assembly 1 in the vertical direction, and the second support assembly 2 has a support plane 201 for supporting the machine tool 6 to be lifted on the side facing the first support assembly 1; wherein the width dimension of the support plane 201 is adapted to the bottom groove of the machine tool 6 to be lifted.

[0038] The lifting device provided in the embodiment of the present disclosure can not only be applied to CNC machine tools, but can also be flexibly applied to all other equipment that meets the lifting conditions of the present disclosure, and has extremely high versatility and adaptability.

[0039] The first support assembly 1 may be a horizontally arranged plate-shaped or beam-shaped structure, and its shape, material and structure must meet sufficient strength and stability. A lifting connection portion 101 is provided in the middle of the first support assembly 1 for direct connection with lifting equipment (such as a crane, a crane, etc.). The lifting connection portion 101 may include structures such as lifting ears, hooks, bolt fixing holes, etc., so as to facilitate quick and accurate hanging of components such as hooks or slings of the lifting equipment.

[0040] The second support assembly 2 is arranged in the same direction as the first support assembly 1, and its two ends are respectively connected to the two ends of the first support assembly 1, thereby forming a stable overall frame structure for accommodating the machine tool 6 to be hoisted, ensuring that the machine tool 6 to be hoisted is placed inside the frame during the hoisting operation. When the first support assembly 1 is raised by the lifting system of the hoisting equipment, the second support assembly 2 can be located directly below the first support assembly 1 in the vertical direction, forming a support system that is linked up and down.

[0041] The second support component 2 has a support plane 201 on the side facing the first support component 1 for supporting the machine tool 6 to be hoisted. The width of the support plane 201 is adapted to the bottom groove of the machine tool 6 to be hoisted, thereby achieving accurate positioning and uniform support of the machine tool 6 to be hoisted, effectively preventing the machine tool 6 to be hoisted from shaking or slipping during the hoisting process, and ensuring the stability and safety of the hoisting process.

[0042] The hoisting device provided by the embodiment of the present disclosure is connected through the two ends of the first support assembly 1 and the two ends of the second support assembly 2, respectively, to form a stable hoisting frame; after the first support assembly 1 is hoisted, the second support assembly 2 can be automatically positioned directly below the first support assembly 1 in the vertical direction, ensuring that the two can work together and synchronously bear the weight of the machine tool 6 to be hoisted; the second support assembly 2 is provided with a support plane 201 that accurately matches the bottom groove of the machine tool 6 to be hoisted, so that when the hoisting is in progress, the second support assembly 2 can be partially embedded in the groove at the bottom of the machine tool to achieve precise docking. It ensures that the machine tool can be firmly fixed on the second support assembly 2 when it is hoisted, and will not be displaced, tilted or turned over, thereby enhancing the stability during the hoisting process, while also avoiding the need for additional hoisting hole processing on the machine tool 6 to be hoisted, and protecting the original structure of the machine tool from damage.

[0043] In some embodiments, Figures 1 to 3 As shown, the lifting device also includes: a plurality of lifting rings 3, with at least one lifting ring 3 being provided at each end of the first supporting assembly 1 and the second supporting assembly 2; at least one pair of lifting ropes 4, with both ends of each lifting rope 4 being hinged to the corresponding lifting rings 3 on the first supporting assembly 1 and the second supporting assembly 2 located on the same side.

[0044] The lifting rings 3 are evenly distributed at the ends of the first supporting assembly 1 and the second supporting assembly 2, providing uniform and reliable connection points for the two supporting assemblies. The two ends of the lifting rope 4 are respectively hinged to the corresponding lifting rings 3 on the first supporting assembly 1 and the second supporting assembly 2 on the same side, forming a connecting link between the first supporting assembly 1 and the second supporting assembly 2. In this way, the two supporting assemblies can maintain their relative positions unchanged during the lifting process, achieve synchronous lifting, and ensure stable load-bearing of the heavy objects to be lifted.

[0045] In order to ensure that the first support assembly 1 and the second support assembly 2 always remain in a parallel state, the lengths of the lifting ropes 4 on both sides must be equal to prevent the heavy object from tilting during the lifting process and ensure the safety of the operation. The lifting rope 4 can be made of a material with high strength and excellent flexibility, such as a steel wire rope composed of steel wire, a rope core and grease. This type of steel wire rope is made of multiple layers of steel wire twisted into strands, and then a number of strands are spirally twisted around the rope core. It has the advantages of high strength, low dead weight, and excellent fracture resistance, and is suitable for heavy-load lifting tasks. The steel wire rope is wound around the lifting ring 3 and can be fixed using an existing wire rope clamp to ensure a stable connection between the steel wire rope and the lifting ring 3 to prevent the rope from slipping during the lifting process.

[0046] By setting lifting rings 3 at both ends of the first support assembly 1 and the second support assembly 2, uniform connection points are provided for the two support assemblies to disperse the tension during the lifting process. The corresponding ends of the two support assemblies are tightly connected by the lifting rope 4 to form an integrated lifting frame. The corresponding ends of the first support assembly 1 and the second support assembly 2 are firmly connected by the lifting rope 4, so that the two support assemblies can maintain strict synchronous lifting during the lifting process, effectively preventing the risk of tilting or overturning of the device caused by uncoordinated lifting. And due to the flexible characteristics of the lifting rope 4, when the first support assembly 1 is hoisted, the second support assembly 2 can be automatically positioned in the vertical direction under the action of gravity to be directly below the first support assembly 1, so that the two support assemblies are accurately aligned during the lifting process, which is conducive to the subsequent stable bearing of the object to be hoisted.

[0047] In some embodiments, the support plane 201 is a rectangular structure, and two groups of rings 3 are respectively provided at both ends along its length direction, each group of rings 3 includes two rings 3, and the two rings 3 are spaced apart along the width direction of the support plane 201.

[0048] The rectangular support plane 201 can provide a stable basic support and a larger contact area to ensure that the entire device remains stable during the hoisting process and prevent tilting or overturning due to uneven force.

[0049] The hoisting device is provided with two sets of lifting rings 3 at both ends along the length direction of the rectangular support plane 201, with a total of four lifting rings 3, corresponding to which four lifting ropes 4 are used. One end of each lifting rope 4 is connected to a lifting ring 3 of the second support assembly 2, and the other end is connected to a lifting ring 3 on the same side of the first support assembly 1. Through the combination of four lifting rings 3 and four lifting ropes 4, multi-point balanced lifting is achieved, which effectively disperses the load, reduces the pressure on a single lifting ring 3, and improves the safety of lifting. During the lifting process, no matter how the machine tool 6 to be lifted rotates, the operator can adjust the angles of the four lifting ropes in time to compensate for the change of the center of gravity in real time to ensure that the entire lifting system remains balanced.

[0050] In some embodiments, the lifting ring 3 is detachably connected to the second supporting assembly 2 , and the detachable connection structure between the second supporting assembly 2 and the lifting ring 3 is disposed below the supporting plane 201 along the vertical direction.

[0051] A detachable connection structure is adopted between the lifting ring 3 and the second supporting assembly 2, such as a bolt connection, a latch connection, a buckle connection, etc., so that the lifting ring 3 can be quickly and conveniently installed or removed when needed.

[0052] The detachable connection structure is arranged below the support plane 201 in the vertical direction. This means that the lifting ring 3 is not directly fixed on the support plane 201, but is connected to the structure below the support plane 201 through a downwardly extending connection member (such as a connection plate, a bracket, etc.). It avoids setting a protruding connection component on the support plane 201, thereby maintaining the flatness of the surface of the support plane 201, ensuring that the support plane 201 and the bottom of the machine tool 6 to be hoisted can fit tightly and flatly, reducing the possibility of collision between the bottom of the machine tool 6 to be hoisted and the connection part during the hoisting process, protecting the structure of the machine tool 6 to be hoisted from accidental impact damage, and also protecting the connection part of the hoisting device itself, extending its service life.

[0053] In some embodiments, the second support assembly 2 includes a first plate body 202 and a second plate body 203 arranged opposite to each other in a vertical direction, and the side of the first plate body 202 facing away from the second plate body 203 is a support plane 201; a plurality of support beams 204 are arranged parallel and evenly spaced between the first plate body 202 and the second plate body 203, and the lifting ring 3 is detachably connected to the support beam 204.

[0054] A plurality of support beams 204 are arranged parallel and evenly spaced between the first plate 202 and the second plate 203. The support beams 204 play a role in strengthening the structure and dispersing the load, thereby improving the overall rigidity and load-bearing capacity of the second support assembly 2. The lifting ring 3 is not directly connected to the first plate 202 or the second plate 203, but is connected to the support beam 204 located between the two in a detachable manner, so that the connection portion between the lifting ring 3 and the second support assembly 2 is arranged below the support plane 201.

[0055] In the embodiment of the present disclosure, the second support assembly 2 may be a structure formed by welding a plurality of I-shaped steels. Figure 1 and Figure 2 As shown, for example, the second support assembly 2 is mainly composed of three I-shaped steel structures arranged in parallel and firmly connected by welding, and then part of the plate structure at both ends of the I-shaped steel structures on both sides is cut off to expose the middle support beam 204, and the lifting ring 3 can be detachably connected to the exposed middle support beam 204. The three I-shaped steel structures are spliced ​​in parallel in the same direction, and the side exposed toward the support beam 204 is defined as the support plane 201, that is, the object to be hoisted will contact this surface to achieve stable load-bearing. There are no obvious welding marks on the support plane 201 to ensure the flatness of the support plane 201.

[0056] In some embodiments, the lifting ring 3 is a U-shaped structure, with a first through hole passing through each of its opposite ends, and a second through hole corresponding to the first through hole passing through the side of the support beam 204 along the width direction, and the width dimension of the support beam 204 is smaller than the distance between the opposite ends of the lifting ring 3; it also includes: a connecting shaft 5, which passes through the first through hole and the second through hole in sequence to connect the lifting ring 3 with the support beam 204.

[0057] The lifting ring 3 is U-shaped, with its opening facing the support beam 204. This allows the two ends of the lifting ring 3 to be placed on both sides of the support beam 204, while maintaining a moderate gap between the lifting ring 3 and the support beam 204. This gap not only satisfies the normal assembly space of the connecting shaft 5, but also avoids the interference of the support beam 204 on the movement of the lifting ring 3, ensuring that the lifting ring 3 can rotate flexibly during the lifting process.

[0058] A first through hole is provided at each of the two opposite ends of the lifting ring 3, and a second through hole corresponding to the first through hole is provided on the side of the support beam 204 along the width direction. The connecting shaft 5 passes through the first through hole of the lifting ring 3 and the second through hole of the support beam 204 in sequence to form a stable connection. It ensures that the lifting ring 3 and the support beam 204 maintain a tight and firm connection during the lifting process, effectively preventing loosening or disengagement, and greatly improving the safety of the lifting operation. And through this connection method, the lifting rope 4 and the lifting ring 3 can also be detachable, which is convenient for changing the length of the lifting rope 4 and improving the adaptability of the lifting device. The connecting shaft 5 can be in the form of a threaded shaft, a pin shaft, etc. to ensure the stability and adjustability of the connection.

[0059] In some embodiments, the lifting device further includes a locking member, and both ends of the connecting shaft 5 are designed with threads. During operation, the connecting shaft 5 can first be passed through the lifting ring 3 and the support beam 204 in sequence, and then two locking members are used to be threadedly connected to the two ends of the connecting shaft 5 respectively, so as to ensure that the connecting shaft 5 maintains a stable contact with the lifting ring 3 and the support beam 204 to prevent separation. The locking member can be a fastener such as a nut. Alternatively, the connecting shaft 5 can be a structure with a protrusion at one end and a thread at the other end. Among them, the size of the protrusion is larger than the size of the corresponding first through hole and second through hole on the lifting ring 3 and the support beam 204, which is also intended to prevent the connecting shaft 5 from accidentally separating from the two during use.

[0060] In some embodiments, the vertical distance between the two opposite sides of the first plate body 202 and the second plate body 203 is not greater than the depth of the bottom groove of the machine tool 6 to be hoisted.

[0061] The vertical distance between the two opposite surfaces of the first plate 202 and the second plate 203 is the height of the second support assembly 2, which is limited to the depth of the groove at the bottom of the machine tool 6 to be hoisted. Figure 6 As shown, the first plate body 202 and the second plate body 203 can be completely embedded in the groove, as shown in FIG. Figure 7As shown, a tight fit is formed with the bottom of the machine tool, thereby achieving a precise match between the second support assembly 2 and the machine tool 6 to be hoisted.

[0062] By setting the height of the second support assembly 2 to be less than the depth of the groove at the bottom of the machine tool 6 to be hoisted, on the one hand, the stability of the hoisting process is greatly enhanced, and the safety hazards such as slippage and tilting caused by poor matching are effectively reduced; on the other hand, the second support assembly 2 can be directly inserted from the bottom of the machine tool without lifting the machine tool 6 to be hoisted in advance, and then conveniently connected to the first support assembly 1 through the lifting rope 4. And because the connection between the lifting ring 3 and the second support assembly 2 is located below the supporting plane 201, in the process of inserting the second support assembly 2 from the bottom of the machine tool, the connection part between the lifting ring 3 and the second support assembly 2 can cleverly avoid contact with the machine tool 6 to be hoisted, effectively avoiding the problem of damage to the marble machine tool that may be caused by the collision between the two. This not only simplifies the installation and fixing steps of the hoisting device, but also significantly enhances the safety of the hoisting operation, ensures that the marble machine tool is intact during the hoisting process, and thus improves the overall operation efficiency.

[0063] In some embodiments, the lengths of the first support assembly 1 and the second support assembly 2 are equal, and their lengths are not less than the length of the machine tool 6 to be hoisted.

[0064] The first support assembly 1 can be constructed of I-shaped steel, and the structures of both ends thereof are similar to those of the second support assembly 2. A portion of the plate surface is cut to expose the middle beam portion so as to achieve a detachable connection with the lifting ring 3. The structure of the lifting ring 3 on the first support assembly 1 and the connection method with the lifting ring 3 can be consistent with those of the second support assembly 2.

[0065] like Figure 6 As shown, since the lengths of the first support assembly 1 and the second support assembly 2 are exactly equal, the hoisting device forms a regular rectangular bearing space, and the machine tool 6 to be hoisted can be safely placed in this space. And since the lengths of the two support assemblies are not less than the length of the machine tool itself, any part of the machine tool can be effectively supported and balanced by the support assemblies. Therefore, no matter what stage the hoisting operation is in, the machine tool can maintain a horizontal and stable posture, effectively eliminating safety hazards such as center of gravity shift and violent shaking caused by local lack of support, and significantly enhancing the overall safety of the hoisting operation. At the same time, it also ensures that there is no direct extrusion contact between the hoisting rope 4 and the machine tool 6 to be hoisted, avoiding accidental damage to the machine tool due to excessive rope pressure during the hoisting process, and further protecting the integrity of the machine tool.

[0066] In some embodiments, the lifting connection portion 101 is ring-shaped, and a pair of reinforcing ribs 102 are symmetrically arranged on both sides of the lifting connection portion 101 .

[0067] like Figures 1 to 8 As shown, the hoisting connection part 101 can adopt a rectangular block structure, with a through hole in the middle to facilitate docking with the hoisting equipment. The hoisting connection part 101 is tightly combined with the I-shaped steel structure of the first support assembly 1 by welding to ensure the structural strength and stability during the hoisting process. On both sides of the annular hoisting connection part 101, a pair of reinforcing ribs 102 are symmetrically arranged and welded or integrally formed. The two reinforcing ribs 102 are plate-shaped, and their shape, size, and material are matched with the hoisting connection part 101, aiming to improve the strength of the connection part without affecting its normal use.

[0068] The reinforcing ribs 102 significantly enhance the overall rigidity and load-bearing performance of the hoisting connection 101, so that it can still maintain excellent mechanical properties when facing a large tensile force. In addition, the symmetrically configured reinforcing ribs 102 effectively ensure the balanced force of the hoisting system as a whole, which is conducive to maintaining the smooth progress of the hoisting operation and further improving the safety and efficiency of the hoisting operation.

[0069] The hoisting device provided in the embodiment of the present disclosure utilizes the specific structure of the machine tool 6 to be hoisted, such as the depth and overall length of the bottom groove, so that the second support assembly 2 can be embedded in the groove, achieving precise alignment and stable connection with the machine tool, avoiding additional hoisting hole processing on the machine tool, and protecting the integrity of the original structure of the machine tool. At the same time, it greatly enhances the stability during the hoisting operation, and fundamentally prevents potential safety hazards such as slippage and tilting during the hoisting process. The hoisting device provided in this embodiment has the advantages of precise matching, protection of the original structure, convenient installation and high safety, and provides an efficient and reliable solution for the hoisting operation of the machine tool 6 to be hoisted.

[0070] Example 2

[0071] An embodiment of the present disclosure provides a transportation system, including the lifting device provided in Embodiment 1 of the present disclosure.

[0072] The transportation system also includes lifting equipment (such as cranes, hoists, etc.), transportation vehicles (such as flatbed trucks, special transport vehicles, etc.), fixing and lashing tools (such as hooks, slings, fastening belts, etc.), and necessary operation control systems and safety monitoring equipment that match the lifting device. These devices work together with the lifting device to complete the entire process from lifting, loading, transportation to unloading.

[0073] In the transportation system, the hoisting device provided in Example 1 is directly responsible for the hoisting and handling operations of the machine tool. With its significant advantages such as precise adaptation to the bottom structure of the machine tool, ensuring stable hoisting, facilitating and quick installation, providing comprehensive support and structural reinforcement, the hoisting device effectively ensures the safe and efficient hoisting of the machine tool during the entire transportation process, and ensures the integrity of the machine tool and the smooth progress of the transportation operation to the greatest extent.

[0074] So far, various embodiments of the present disclosure have been described in detail.
