Description

Technical Field

[0001] This application belongs to the field of building engineering technology, and in particular relates to a crane system and a method for replacing the crane system. Background Technology

[0002] In heavy industrial plants, overhead cranes are crucial equipment for material handling and process integration. As the basic track support structure for crane operation, the first crane beam bears complex cyclic loads over a long period, including vertical wheel pressure, longitudinal horizontal braking force, and lateral horizontal swaying force. Especially in high-intensity operating environments such as metallurgy and forging, the crane's working level is often under high load. After long-term service, the first crane beam may develop cracks or even fractures due to fatigue accumulation, directly threatening production safety.

[0003] In traditional engineering design, to resist the lateral swaying force caused by crane operation and ensure the overall stability of the upper flange of the crane beam, the horizontal support system and pipelines (including conductor rails, control cables, fluid medium pipelines, etc.) are often rigidly connected to the bottom of the first crane beam and the longitudinal stiffening ribs to provide necessary lateral anti-torsional constraints. This highly dependent design, stemming from mechanical constraint requirements, means that the conductor rail is usually run through or fixed in the web or lower flange area of ​​the first crane beam, while the cable is laid along the beam surface and rigidly connected to the beam body through binding or cable trays.

[0004] When the first crane beam needs to be replaced entirely due to fatigue damage or reaching the end of its service life, all the sliding wires, cables, and piping systems attached to it must first be completely removed. This involves multiple complex procedures, including power outages, wire disconnection, pipe emptying and cutting, temporary support, and re-laying, significantly extending the production interruption cycle and resulting in considerable economic losses. Furthermore, the moment the old beam is removed, the vertical supports and pipe hangers originally attached to the longitudinal stiffening ribs of the crane beam instantly lose their upward reaction force and lateral stability points. The release of gravity and residual lateral stress can easily cause pipe instability, twisting and breakage, and cable falls, further exacerbating the difficulty of project implementation and safety risks.

[0020] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0021] In heavy industrial plant environments, bridge cranes, as core material handling devices, rely heavily on the structural reliability of their first crane beam for stable operation. This system is subjected to multiple cyclic loads over long periods, including vertical wheel pressure, longitudinal horizontal braking force, and lateral horizontal swaying force. Especially in high-intensity operating scenarios such as metallurgy and forging, the crane's working level is often under high load, making the first crane beam prone to fatigue cracks or even fracture during long-term service, seriously threatening production safety.

[0022] Traditional first crane beam designs integrate auxiliary facilities with the main structure. The guide wires are directly threaded through or fixed to the web and lower flange of the first crane beam, while cables are laid along the beam surface and rigidly connected to the beam via binding or cable trays. While this design meets routine operational needs, it reveals significant drawbacks when the first crane beam requires complete replacement due to fatigue damage or the end of its lifespan. All guide wires and cables must be removed first, involving complex procedures such as power outages, cable removal, temporary support, and re-laying. This process not only significantly extends production downtime and incurs considerable economic losses, but the complete dependence of the auxiliary facilities on the first crane beam itself means that pipelines will fail simultaneously during replacement, requiring additional evacuation, disconnection, and dismantling, further increasing the difficulty of implementation and the duration of downtime.

[0023] The following is for reference. Figures 1-3 This application describes a crane system and a method for replacing the crane system according to embodiments of the present application.

[0024] like Figure 1 and Figure 2 As shown, the crane system includes: a support body 100, a first crane beam 200, and a support component 300.

[0025] The supporting body 100 includes multiple column assemblies 110, a brake plate 120, and a horizontal beam 130; the multiple column assemblies 110 are arranged in parallel and spaced apart, each column assembly 110 including a first column 111 and a second column 112, the second column 112 being vertically mounted on the first column 111; the brake plate 120 is connected between two adjacent second columns 112; the horizontal beam 130 is disposed between two adjacent first columns 111; The first crane beam 200 is connected between the brake plate 120 and the first column 111. The first crane beam 200 is used to install a crane assembly. The crane assembly is connected to a sliding line and a cable. The sliding line passes through the first crane beam 200 and is electrically connected to the cable. The support member 300 is disposed on the horizontal beam 130, and the cable is mounted on the support member 300. Alternatively, the cable can be placed on the supporting surface of the support member 300 and secured with cable ties or clamps, thereby allowing the cable to be laid independently of the first crane beam 200.

[0026] This application allows the cable to be independently installed on the horizontal beam 130 via the support member 300, effectively separating the cable from the first crane beam 200. Therefore, when the first crane beam 200 needs replacement, there is no need for large-scale dismantling and re-laying of the cable, significantly shortening downtime, reducing the workload of replacement operations, and avoiding potential damage to the cable during dismantling and installation, thereby improving replacement efficiency and the safety of the electrical system.

[0027] In related technologies, the horizontal beam 130 is typically connected to the bottom of the first crane beam 200, and the bottom of the horizontal beam 130 is connected to a hanger 160 for suspending and supporting the pipes. This maintains the lateral stability of the first crane beam 200.

[0028] It should be noted that the first crane beam 200, under the pressure of the crane wheel, is highly susceptible to lateral torsional instability. Connecting the horizontal beam 130 to the lower flange provides continuous lateral restraint to the bottom of the first crane beam 200. However, during crane beam replacement, the horizontal beam 130 and the hanger 160 must also be removed, and the pipelines must be emptied, cut off, and dismantled, which prolongs the downtime.

[0029] like Figure 3 As shown, in some embodiments, the support body 100 further includes: a crossbeam 140, a plurality of hangers 150, and a hanger 160; The crossbeam 140 is located above the brake plate 120 and is connected between two adjacent second columns 112; One end of each of the plurality of booms 150 is connected to the crossbeam 140, and the other end of each of the plurality of booms 150 passes through the brake plate 120 and is connected to the horizontal beam 130; The hanger 160 is connected to the side of the horizontal beam 130 away from the boom 150. The hanger 160 is used to lift the pipe. In the conventional design, the horizontal beam 130 is connected to the bottom of the first crane beam 200.

[0030] This embodiment constructs a vertical force transmission path independent of the first crane beam 200 by adding a crossbeam 140 and a hanger 150. The hanger 150 extends downward from the crossbeam 140 and suspends the horizontal beam 130, so that the pipeline supported by the horizontal beam 130 and the hanger 160 below it is completely transferred to the upper crossbeam 140 for support, no longer relying on the first crane beam 200. Therefore, when replacing the first crane beam 200, the pipeline remains suspended in place through the path of hanger 160 → horizontal beam 130 → hanger 150 → crossbeam 140, without the need for evacuation, cutting, or dismantling, directly eliminating the problem of long-term production stoppage caused by pipeline dismantling and installation in related technologies.

[0031] In some embodiments, the support body 100 further includes: a plurality of vertical support components 170; The plurality of vertical support components 170 are parallel to each other and spaced apart along the length of the brake plate 120. One end of each vertical support component 170 is connected to the lower end face of the brake plate 120, and the other end is connected to the horizontal beam 130.

[0032] In this embodiment, by introducing multiple vertical support components 170 and establishing a direct vertical connection between the lower end face of the brake plate 120 and the horizontal beam 130, this application effectively solves the problems of insufficient stiffness and poor load transfer that may exist between the brake plate 120 and the horizontal beam 130. These vertical support components 170 can directly and evenly transfer the vertical load generated by the first crane beam 200 and the overhead crane assembly to the horizontal beam 130 through the brake plate 120, avoiding the stress concentration and structural deformation risks caused by the indirect transfer of load mainly through the column assembly 110. This direct vertical support significantly enhances the vertical bearing capacity and bending stiffness of the horizontal beam 130, ensuring that the horizontal beam 130 can maintain a stable support state even when facing dynamic impact loads during the operation of the crane system, thereby improving the structural reliability and service life of the entire crane system. At the same time, due to the improved stability of the horizontal beam 130, the cables and pipes carried by the support components 300 and the hangers 160 installed on it can also obtain more reliable support, further ensuring the safe operation of auxiliary facilities.

[0033] In some embodiments, the lower end face of the brake plate 120 is further connected to a plurality of reinforcing ribs 121; the vertical support assembly 170 includes a first support portion 171 and a second support portion 172 arranged in a cross configuration, one end of the first support portion 171 and the second support portion 172 are both connected to the reinforcing ribs 121, the other end of the first support portion 171 and the second support portion 172 are both connected to the horizontal beam 130, and the intersection of the first support portion 171 and the second support portion 172 is connected to the hanger rod 150.

[0034] Through the above technical solution, the vertical support assembly 170 is designed with a first support portion 171 and a second support portion 172 arranged in a cross configuration. This significantly improves the overall rigidity and deformation resistance of the connection between the brake plate 120 and the horizontal beam 130, enabling it to more effectively resist the vertical loads, lateral forces, and torsional moments generated during the operation of the crane system. Furthermore, by connecting the intersection of the first support portion 171 and the second support portion 172 to the boom 150, the vertical support assembly 170 and the boom 150 form a cohesive whole, optimizing the mechanical transmission path of the entire support system. This achieves a more uniform distribution of load within the support body 100, effectively reducing the stress on individual components. Consequently, it significantly improves the overall structural stability, safety, and service life of the crane system, ensuring reliable operation of the crane system under various working conditions.

[0035] In some embodiments, the support body 100 further includes: a plurality of diagonal braces 180; One end of each of the diagonal braces 180 is connected to the second column 112, and the other end of the diagonal brace 180 is connected to the crossbeam 140.

[0036] Through the above technical solution, a diagonal brace 180 is added between the second column 112 and the crossbeam 140, forming a stable triangular support structure. This ensures that the crossbeam 140 can more reliably support the hanger 150, thereby stably supporting the pipes carried by the horizontal beam 130 and the hanger 160.

[0037] In some embodiments, the bottom of the hanger 160 is provided with a plurality of support plates, which are parallel to each other and spaced apart in the height direction of the first column 111, and each support plate is used to support the pipe.

[0038] Through the above technical solution, multiple parallel support plates spaced apart at the height of the first column 111 are installed at the bottom of the hanger 160. This design enables the hanger 160 to stably support multiple pipes and effectively cope with the needs of pipe height differences. At the same time, the layered support also makes the pipe layout more orderly and facilitates daily maintenance and management.

[0039] In some embodiments, the support 300 includes a support 310 and a cable tray 320; The support 310 is connected to the horizontal beam 130, the cable rack 320 is connected to the support 310, and the cable rack 320 is provided with a cable groove for placing cables.

[0040] In some embodiments, a walkway is also connected to the horizontal beam 130, the walkway being located directly below the brake plate 120 and arranged along the length of the first crane beam 200.

[0041] Through the above technical solution, the walkway is set on the horizontal beam 130 directly below the brake plate 120, forming a working platform between the elevation of the brake plate 120 and the elevation of the horizontal beam 130, which allows construction personnel to perform maintenance operations. Maintenance personnel can easily access key components such as the first crane beam 200, guide rails, cables, and pipes through this walkway for routine inspections, maintenance, and troubleshooting. This significantly reduces the risks of working at heights, improves the efficiency and safety of maintenance operations, and reduces downtime caused by maintenance work.

[0042] On the other hand, this application also provides a method for replacing a crane system, including: S1. Cancel the connection between the brake plate 120 and the first crane beam 200; S2. Cancel the connection between the first crane beam 200 and the first column 111; S3. Disconnect the first crane beam 200 and the sliding line from the cable; S4. Provide a second crane beam and connect the second crane beam to the brake plate 120; S5. Connect the second crane beam to the first column 111; S6. Pass the sliding line through the second crane beam and connect it electrically to the cable.

[0043] By relocating the cable installation from the crane beam itself to the support member 300 on the horizontal beam 130, the cable can be replaced without removal; only the connection between the cable guide and the cable needs to be temporarily disconnected. This significantly reduces downtime, workload, and electrical safety hazards. Specifically, because the support member 300 is independently mounted on the horizontal beam 130, the cable remains fixed throughout the replacement process, avoiding the risk of insulation damage caused by disassembly and reassembly in traditional solutions. Furthermore, the cable guide only needs to be reconnected to the new crane beam, eliminating the need for complex cable laying procedures.

[0044] Through the above technical solution, crane beam replacement operations are simplified to replacing the crane beam itself, shortening the downtime. Furthermore, this method effectively avoids electrical safety hazards during cable installation and removal, ensuring a reliable power supply to the crane system after it resumes operation. Overall, this replacement method, through optimized structural design, decouples auxiliary facilities from the main structure, providing technical support for efficient maintenance of heavy industrial plants.

[0045] In some embodiments, canceling the connection between the brake plate 120 and the first crane beam 200 includes: The portion connecting the brake plate 120 to the first crane beam 200 is partially cut off; The provision of a second crane beam, connecting the second crane beam to the brake plate 120, includes: A connecting plate is also provided to connect the second crane beam to the connecting plate; Connect the connecting plate to the brake plate 120; And / or, the replacement method further includes: A reinforcing rib 121 is provided, the reinforcing rib 121 being connected to the lower end face of the brake plate 120; The reinforcing rib 121 is connected to the second crane beam.

[0046] Through the above technical solution, during the replacement of the crane system, even when facing permanent connections or damaged structures, the old first crane beam 200 can be quickly separated by partially cutting off the brake plate 120. The introduction of connecting plates and reinforcing ribs 121 provides a stable, reliable, and structurally reinforced connection foundation for the new second crane beam. Simultaneously, since only the brake plate section connected to the first crane beam 200 is removed while retaining the original reinforcing ribs 121, and the new brake plate section pre-installed on the second crane beam is connected to the cut end of the original brake plate 120, large-area hot work and welding are avoided, ensuring high-precision repositioning. This not only significantly shortens the downtime of the replacement operation and reduces construction difficulty and workload, but also significantly improves the overall structural strength and operational safety of the replaced crane system, ensuring that the equipment can quickly return to normal operation and meet stringent load-bearing requirements.

[0047] In some embodiments, the crane system is further equipped with a hydraulic jack system for three-dimensional fine-tuning and alignment after the new crane beam is hoisted and positioned. Specifically, multiple sets of linked hydraulic jacks are installed between the end of the second crane beam and the second column 112. The precise correction of the position of the second crane beam component is completed by the inward and outward pushing of the jacks. The operation of the hydraulic jacks relies on the walkway on the horizontal beam 130 as the operating surface.
