Description

Technical Field

[0001] This application relates to the field of chimney installation technology, and in particular to an integrated device for chimney hoisting and welding protection. Background Technology

[0002] In the on-site installation of steel chimneys, especially large sleeve-type or multi-cylinder steel chimneys, the hoisting and welding of the chimney wall panels are the core processes. Currently, the industry's conventional hoisting and internal wall welding protective devices mainly rely on the following two technical solutions:

[0003] The first option is to "weld lifting lugs on the outside and erect full-span scaffolding inside." Specifically, temporary lifting lugs are welded to the outside of the chimney panels for lifting and positioning, while a full-span scaffolding platform is erected inside the chimney from the ground up to provide a platform for construction workers to perform internal wall welding, grinding, and inspection operations.

[0004] The second option is the "external welding of lifting lugs and internal welding of lifting lugs" method. This option also involves welding lifting lugs to the outside of the wall panels. To reduce the amount of scaffolding used, except for the wall panels required for the top layer of work, supporting lifting lugs or brackets for supporting the scaffolding must be welded to the inner walls of the remaining installed chimney wall panels, thereby suspending the segmented scaffolding on the inner wall of the chimney.

[0005] However, the aforementioned existing technical solutions all share a common drawback that cannot be ignored: both rely heavily on the erection and dismantling of scaffolding, a process that is cumbersome and time-consuming. Utility Model Content

[0046] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0047] See Figures 1-6 This invention illustrates a preferred embodiment of an integrated hoisting and welding protection device for chimneys, comprising:

[0048] Support component 1, which is used to be disposed on top of or above the chimney 20;

[0049] Multiple first connecting members 2 are provided on the top of the support member 1, and the multiple first connecting members 2 are arranged sequentially around the vertical center line of the support member 1.

[0050] The first lifting rope 3 connects to multiple first connecting components 2, and the first lifting rope 3 is also used to connect to lifting equipment;

[0051] Multiple second connecting members 4 are disposed at the bottom of the support member 1, and the multiple second connecting members 4 are arranged sequentially around the vertical center line of the support member 1;

[0052] Multiple second lifting ropes 5, the upper end of each second lifting rope 5 is connected to the corresponding second connecting member 4, and the lower end of each second lifting rope 5 is detachably connected to the lifting lug 30 on the outer wall of the corresponding chimney 20 wall panel.

[0053] Multiple third connecting members 6 are located at the bottom of the support member 1. The multiple third connecting members 6 are arranged sequentially around the vertical center line of the support member 1. Each of the multiple third connecting members 6 is surrounded by multiple second connecting members 4.

[0054] Welding platform 7 is used to be configured in the center hole of chimney 20;

[0055] Multiple third lifting ropes 8, the upper end of each third lifting rope 8 is connected to a corresponding third connecting member 6, and the lower end of each third lifting rope 8 is connected to a welding operation platform 7; and

[0056] The retractable ladder 9 has its upper end connected to the support component 1 and its lower end connected to the welding operation platform 7.

[0057] This utility model discloses an integrated hoisting and welding protection device for chimneys, comprising a support component 1, a first connecting component 2, a first lifting rope 3, a second connecting component 4, a second lifting rope 5, a third connecting component 6, a welding operation platform 7, a third lifting rope 8, and a retractable ladder 9. Specifically, the first lifting rope 3 connects the first connecting component 2 on the support component 1 to external hoisting equipment, thereby connecting the support component 1 to the hoisting equipment and enabling the hoisting of the support component 1; the second lifting rope 5 connects the second connecting component 4 on the support component 1 to the lifting lugs 30 on the outer wall of the chimney 20 wall panel, thereby connecting the support component 1 to the chimney 20 wall panel and enabling the hoisting of the chimney 20 wall panel; the third lifting rope 8 connects the third connecting component 6 on the support component 1 to the welding operation platform 7, thereby connecting the welding operation platform 7 to the support component 1 and enabling the hoisting and support of the welding operation platform 7. In practical applications, the chimney 20 wall panels are first connected to this device via the second hoisting rope 5. Then, the device, along with the chimney 20 wall panels, is hoisted to the designated work position using hoisting equipment. Subsequently, the support platform is placed on top of the chimney 20, with the chimney 20 itself bearing the load of the welding platform 7. After the hoisting equipment is disconnected, welding personnel can enter and exit the welding platform 7 via the retractable ladder 9 and stand on the welding platform 7 to perform welding operations on adjacent chimney 20 wall panels. This device eliminates the need for traditional scaffolding, making disassembly and assembly simpler and more convenient, thus improving work efficiency. Furthermore, this device applies vertical force to the chimney 20 wall panels during hoisting and welding operations, avoiding the lateral force generated during traditional scaffolding connections. This effectively prevents deformation of the chimney 20 wall panels and ensures the overall construction quality of the chimney 20.

[0058] For easy connection of welding platform 7, see [link / reference] Figure 1 In one embodiment, the welding platform 7 is provided with a plurality of fourth connecting members 10, which are arranged sequentially around the vertical center line of the welding platform 7, and each fourth connecting member 10 is connected to the lower end of the corresponding third lifting rope 8.

[0059] In one embodiment, the upper end of each second suspension rope 5 is detachably connected to the corresponding second connecting member 4, so that the upper end of the second suspension rope 5 can be removed from the second connecting member 4, making it convenient to replace the second suspension rope 5.

[0060] The upper end of each third lifting rope 8 is detachably connected to the corresponding third connecting member 6, and the lower end of each third lifting rope 8 is detachably connected to the corresponding fourth connecting member 10, so that the third lifting rope 8 can be disassembled and installed, facilitating the replacement of the third lifting rope 8.

[0061] In one embodiment, the first connecting member 2, the second connecting member 4, the third connecting member 6, and the fourth connecting member 10 are all provided with lifting holes, that is, the first connecting member 2, the second connecting member 4, the third connecting member 6, and the fourth connecting member 10 are all lifting lugs, which facilitates connection and improves the lifting and installation performance.

[0062] Of course, in other embodiments, the first connecting member 2, the second connecting member 4, the third connecting member 6 and the fourth connecting member 10 can all be hooks, which can also facilitate hoisting.

[0063] Specifically, the first connecting member 2, the second connecting member 4, and the third connecting member 6 can all be connected to the support member 1 by welding, or they can be integrally formed with the support member 1, or they can be connected to the support member 1 by bolts.

[0064] Similarly, the fourth connecting member 10 can be connected to the welding platform 7 by welding, or it can be integrally formed with the welding platform 7, or it can be connected to the support member 1 by bolts.

[0065] See Figures 3-4 In one embodiment, the support member 1 includes:

[0066] The annular frame 11 is provided with the aforementioned first connecting member 2 and second connecting member 4, that is, the aforementioned first connecting member 2 and second connecting member 4 are mounted on the annular frame 11; and

[0067] A reinforcing structure 12 is mounted on the annular frame 11 and supports the annular frame 11. The reinforcing structure 12 includes the aforementioned third connecting member 6, which is installed on the reinforcing structure 12. This support component 1, composed of the annular frame 11 and the reinforcing structure 12, forms a frame structure. On the one hand, this reduces the overall weight of the support component 1, thereby reducing the difficulty of hoisting. On the other hand, the arrangement of the reinforcing structure 12 on the annular frame 11 enhances the overall structural strength of the annular frame 11, ensuring that the support component 1 can stably support the welding platform 7 and the chimney 20.

[0068] See Figure 4 In one embodiment, the reinforcing structure 12 includes:

[0069] The first crossbeam 121, with its two ends respectively connected to the opposite ends of the annular frame 11; and

[0070] The second crossbeam 122 connects to the opposite ends of the ring frame 11 at both ends, and intersects with the first crossbeam 121. That is, the first crossbeam 121 and the second crossbeam 122 are intersected on the ring frame 11, which not only improves the overall structural stability and load-bearing strength of the ring frame 11, effectively resisting loads in all directions and preventing frame deformation, but also results in a compact structure, achieving optimal reinforcement while maintaining structural lightweight.

[0071] See Figure 4 In one embodiment, the annular frame 11 is rectangular. The two ends of the first crossbeam 121 are respectively connected to two opposite corners of the annular frame 11, and the two ends of the second crossbeam 122 are respectively connected to two other opposite corners of the annular frame 11. By setting the annular frame 11 as a rectangle and connecting the first crossbeam 121 and the second crossbeam 122 to two sets of corners on the annular frame 11, a pair of diagonally intersecting X-shaped reinforcing structures 12 are formed inside the rectangular annular frame 11. This structure makes full use of the geometric characteristics of the rectangle and the force transmission path of the diagonal, which not only greatly enhances the overall stiffness and torsional stability of the annular frame 11, but also effectively disperses and resists loads from different directions and prevents the annular frame 11 from rhomboid distortion. Moreover, this arrangement is simple in structure and achieves the best load-bearing and reinforcement effect with the least amount of material.

[0072] See Figure 4 In one embodiment, the annular frame 11 includes:

[0073] Four third crossbeams 111 are connected end to end. By using four third crossbeams 111 connected end to end to form a ring frame 11, a modular structure is formed. This structure not only has strong integrity and high stability, but also effectively achieves uniform distribution and transmission of load on the ring frame 11 and resists overall deformation. Furthermore, the uniformity of component forms simplifies the manufacturing and assembly process and improves the standardization and scalability of the structure.

[0074] Specifically, in one embodiment, two adjacent third crossbeams 111 are connected by welding, and the first crossbeam 121 and the second crossbeam 122 are respectively connected to the third crossbeam 111 by welding. By connecting adjacent third crossbeams 111 by welding to form a ring frame 11, and by fixing the first crossbeam 121, the second crossbeam 122 and the third crossbeam 111 by welding, a more robust and sturdy structure is formed, which can significantly improve the overall rigidity and load-bearing stability of the support component 1. Furthermore, by simplifying the connection, the weight and complexity brought by additional connecting parts are avoided, making the structure simpler and more reliable.

[0075] Of course, in other embodiments, the two adjacent third crossbeams 111 can also be connected together by fasteners such as bolts and rivets, and the first crossbeam 121 and the second crossbeam 122 can also be connected to the third crossbeam 111 by fasteners such as bolts and rivets.

[0076] See Figures 5-6 In one embodiment, the welding platform 7 includes:

[0077] The outer edge of the annular platform 71 is configured to be positioned close to the inner wall of the chimney 20;

[0078] A protective railing 72 is located at the top inner edge of the annular platform 71, surrounding the vertical centerline of the annular platform 71. The protective railing 72 and the annular platform 71 together form a working passage. By using an annular platform 71 with its outer edge close to the inner wall of the chimney 20, combined with the protective railing 72 located at the top inner edge of the platform, a semi-enclosed welding operation space with a defined working passage is formed. This welding operation platform 7 not only utilizes the annular structural characteristics inside the chimney 20, allowing workers to be close to the welding position and facilitating continuous circumferential construction, effectively improving the convenience and efficiency of welding operations, but also the internal surrounding protective railing 72 forms a reliable installation protection boundary within the limited space, preventing welding workers or tools from accidentally falling. This achieves efficient utilization of the welding operation space and improves construction safety.

[0079] Specifically, in one embodiment, the ring platform 71 and the guardrail 72 can be connected together by any of the following methods: welding, bolting, riveting, etc.
