Description

Technical Field

[0001] This utility model relates to the field of thickener installation technology, and in particular to a floating platform for welding thickener barrels. Background Technology

[0002] Currently, the inverted installation method is mainly used in the construction of existing thickeners. The inverted installation method requires welding the cylinder at a high position. Moreover, if leakage is found in the tightness test, the cylinder can only be emptied again, repaired, and the above steps repeated, which is time-consuming, labor-intensive, and expensive in terms of machinery.

[0003] Traditional installation methods require external workers to use aerial work platforms for height work during the upward installation of the bucket. If four people are working simultaneously, four aerial work platforms are needed, and for safety, each platform must be operated by a two-person team, meaning an additional four people are required for supervision. While aerial work platforms can be used for work on the outside of the bucket, as work moves inside, the working height increases with each layer, and the scaffolding gradually becomes insufficient for the construction needs. At this point, either ladders must be used for work at height, or a platform must be built. However, transporting materials from the outside to the inside of the bucket is a major challenge, and subsequent work and dismantling become difficult. If leaks are found during the leak testing after dismantling, the platform must be rebuilt, which is not only time-consuming, labor-intensive, and material-intensive, but also poses a significant safety hazard.

[0004] Among the construction techniques for floating roof tanks, which are also large-scale tank structures, there is the water-floating installation method. If this method could be referenced and adapted, it could solve safety issues during construction. However, the floating platform used in floating roof tanks is an internal floating roof, so there is no need to consider the disassembly and removal of the floating platform after construction. If the water-floating installation method were to be adopted for thickeners, it would be necessary to address how to provide a safe construction environment for the floating platform during construction and how to handle its disassembly and removal after completion. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a floating platform for welding the body of a thickener barrel, which solves the problem that the existing water-floating positive installation method cannot be applied to the construction process of non-floating roof tanks.

The first locking structure is disposed between the barrel of the thickener and the corner floating platform, and the second locking structure is disposed between the barrel of the thickener and the protective fence.

[0010] In one embodiment, the first locking structure includes a first fixing member and a first connecting member. The first fixing member includes a central ring portion and a side diffusion portion. The central ring portion is distributed in a vertical direction, and the side diffusion portion extends from the upper and lower ends of the central ring portion to the left and right sides of the central ring portion. The central ring portion is connected to the barrel of the thickener. One end of the first connecting member is connected to the corner floating platform, and the other end of the first connecting member is connected to the central ring portion.

[0011] In one embodiment, the second locking structure includes a second connector, one end of which is provided with an adsorption element that adsorbs onto the barrel of the thickener; the other end of the second connector is detachably connected to a protective fence.

[0012] In one embodiment, a third link is also included. A fixing lug is provided on the protective fence, and the third link passes through the fixing lug and is screwed to the first link or the second link.

[0013] In one embodiment, the buoyancy of the corner floating platform is greater than the weight of the work surface and protective fence set on the corresponding corner floating platform.

[0014] In one embodiment, four sets of corner floating platforms are provided, and the corner floating platforms and the central floating platform are connected to form a cross shape.

[0015] In one embodiment, the corner floating platform includes a corner frame and corner pontoons, with the corner pontoons fixed inside the corner frame; the corner frame is connected to the work surface and / or a protective fence.

[0017] In one embodiment, a lifting ring is provided at the top of the central frame.

[0018] The beneficial effects of this utility model are as follows: The floating platform for welding thickener barrels provided by this utility model connects the central floating platform and the corner floating platforms through a detachable first connecting rod, forming a stable and safe floating working plane. A work surface and protective railing are installed on the top of the corner floating platforms, providing a construction site while ensuring the safety of construction personnel.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] In the description of this utility model, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] The existing methods for constructing thickeners, such as the upright and inverted methods, have low safety and efficiency, while the water-floating upright method is not applicable to the construction process of non-floating roof tanks.

[0029] Based on this, please refer to Figures 1 to 4 A floating platform 1 for welding a thickener barrel is disclosed, used for segmented welding inside the thickener. It includes a central floating platform 11, at least three sets of corner floating platforms 12, and a first connecting rod 13. The corner floating platforms 12 are detachably connected to the central floating platform 11 via the first connecting rod 13. Specifically, the corner floating platforms 12 are evenly spaced around the central floating platform 11, forming a stable floating plane. The detachable connection allows the corner floating platforms 12 and the central floating platform 11 to be disassembled after welding and removed from the top of the thickener by hoisting or segmented transport. Preferably, both ends of the first connecting rod 13 are screwed to the corner floating platforms 12 and the central floating platform 11, ensuring overall stability during construction while facilitating disassembly.

[0030] The corner floating platform 12 is equipped with a work surface 121 on its top and a protective fence 122 surrounding the work surface 121. A second connecting rod 14 is installed between adjacent protective fences 122. After the first connecting rod 13 and the second connecting rod 14 are installed, the corner floating platform 12 and the central floating platform 11 together form a stable whole. This can evenly distribute the gravity on the work surface 121 at different positions onto the floating plane formed by the corner floating platform 12 and the central floating platform 11, avoiding excessive stress and tilting in the area, and improving the stability of the construction environment.

[0031] It also includes a side fixing mechanism 3, which is used to limit the position of the corner floating platform 12 and the central floating platform 11 inside the thickener. After the side fixing mechanism 3 is set, the relative position and angle of the floating platform inside the tank 2 can be locked, ensuring the stability of the construction environment.

[0032] It is understood that the floating platform 1 for welding thickener barrels provided by this utility model connects the central floating platform 11 and the corner floating platforms 12 via a detachable first connecting rod 13, forming a stable and safe floating working plane. A work surface 121 and a protective railing 122 are provided on the top of the corner floating platforms 12, providing a construction site while ensuring the safety of construction personnel. Furthermore, it can be disassembled after construction, allowing for easy removal from inside the thickener, enabling the application of the water-floating installation method in thickener construction. Simultaneously, water injection during construction can detect leaks in advance, reducing leakage problems, avoiding rework, and effectively improving construction safety and efficiency. Moreover, the floating platform 1 for welding thickener barrels provided by this utility model, through the side fixing mechanism 3, allows the floating platform to rotate or be fixed as a whole, flexibly adjusting the construction position while ensuring a stable construction environment, thereby guaranteeing work efficiency.

[0033] Preferably, the first link 13 or the second link 14 is made of hollow aluminum tube or iron tube, so as to reduce weight as much as possible while ensuring mechanical strength.

[0034] Preferably, the first connecting rod 13 and the second connecting rod 14 are multi-segment hinged connecting rods. This design allows the first connecting rod 13 and the second connecting rod 14 to be easily unfolded or folded, improving the efficiency of the installation and disassembly process. Furthermore, during disassembly, folding the first connecting rod 13 and the second connecting rod 14 effectively prevents them from scratching the inner wall of the thickener, thus ensuring the safety of the thickener.

[0035] Furthermore, the side fixing mechanism 3 includes a first locking structure 31 and a second locking structure 32. The first locking structure 31 is disposed between the thickener's barrel 2 and the corner floating platform 12, and the second locking structure 32 is disposed between the thickener's barrel 2 and the protective fence 122. Specifically, after the first locking structure 31 is installed, the entire floating platform is angle-locked, ensuring the stability of the construction environment. The second locking structure 32 strengthens the connection between the protective fence 122 and the thickener's barrel 2, reducing vibration caused by the height difference between the worktable 121 and the corner floating platform 12, further ensuring the stability of the construction process and reducing the impact of environmental factors on construction quality. Moreover, the second locking structure 32 can lock the platform in case the first locking structure 31 falls off, further enhancing the safety of the floating platform.

[0036] Furthermore, the first locking structure 31 includes a first fixing member 311 and a first connecting member 312. The first fixing member 311 includes a central ring portion 311a and a side diffuser portion 312b. The central ring portion 311a is distributed vertically, and the side diffuser portions 312b extend from the upper and lower ends of the central ring portion 311a to the left and right sides of the central ring portion 311a. The central ring portion 311a is connected to the barrel 2 of the thickener. One end of the first connecting member 312 is connected to the corner floating platform 12, and the other end of the first connecting member 312 is connected to the central ring portion 311a. Specifically, the first fixing member 311 is disposed on the inner wall of the thickener, one end of the first connecting member 312 is detachably connected to the corner floating platform 12, and the other end of the first connecting member 312 is provided with a hook to connect to the central ring portion 311a. The side diffuser 312b is inclined to guide the first connector 312, facilitating the connection between the first connector 312 and the first fixing member 311 even when the first fixing member 311 is underwater. The first connector 312 ensures that the floating platform does not rotate or shift during construction, guaranteeing a stable construction environment. Preferably, the first fixing member 311 can be welded to the inner wall of the thickener, ensuring it does not detach under the tension of the floating platform. Specifically, the side diffuser 312b can be a flat plate or an arc-shaped plate. Those skilled in the art can adjust the thickness of the central ring 311a, the size of the central hole, and the shape and inclination angle of the side diffuser 312b as needed to achieve the connection between the first connector 312 and the first fixing member 311; no specific limitation is imposed.

[0037] Preferably, the first connector 312 is hinged to the corner floating platform 12. The end of the first connector 312 near the corner floating platform 12 is provided with a pull rod extending to the workbench 121. The pull rod drives the first connector 312 to rotate, thereby completing the connection with the first fixing member 311. This arrangement allows the construction personnel to operate the first connector 312 on the workbench 121, which is convenient for the operators.

[0038] Furthermore, at the same height, at least four first fasteners 311 are spaced apart around the inner wall of the thickener. Specifically, at least four first fasteners 311 are provided on each layer of the thickener tank 2 to ensure that the floating platform as a whole can be fully fixed and its angle adjusted, thus ensuring construction efficiency. Those skilled in the art can adjust the number of first fasteners 311 according to the diameter of the thickener, without making a specific limitation.

[0039] Furthermore, the second locking structure 32 includes a second connector 321, one end of which is provided with an adsorption element 322, which is adsorbed onto the barrel 2 of the thickener; the other end of the second connector 321 is detachably connected to the protective fence 122.

[0040] Furthermore, the first connector 312 and the second connector 321 are telescopic rods. The use of a telescopic rod structure for the first connector 312 and the second connector 321 makes it easier for construction personnel to adjust the angle of the floating platform, and allows for quick fixing after adjustment, thereby improving construction efficiency.

[0041] Furthermore, it also includes a third connecting rod 15. A fixing lug is provided on the protective fence 122, and the third connecting rod 15 passes through the fixing lug and is screwed to the first connecting rod 13 or the second connecting rod 14. Specifically, the first connecting rod 13 and the second connecting rod 14 have screw holes on the side near the corner floating platform 12, and one end of the third connecting rod 15 has threads. The third connecting rod 15 passes through the fixing lug and is screwed to the screw hole. Specifically, a limiting block is provided at the top of the third connecting rod 15 to prevent it from slipping and falling. This design allows construction workers to lift the third connecting rod 15 from the work platform 121 to expose the first connecting rod 13 or the second connecting rod 14 above the water surface. Simultaneously, the entire process of disassembling and separating the corner floating platform 12 does not require construction workers to enter the water, further improving the safety of construction workers and preventing drowning.

[0042] Furthermore, the buoyancy of the corner floating platform 12 is greater than the weight of the work surface 121 and the protective railing 122 set on the corresponding corner floating platform 12. This arrangement ensures that the corner floating platform 12 can float on its own after disassembly and will not sink. Specifically, each corner floating platform 12 must provide a buoyancy of at least 600 kg to further ensure that construction personnel and equipment do not sink after entering the floating platform, thus ensuring a safe construction environment.

[0043] Furthermore, four sets of corner floating platforms 12 are provided, and the corner floating platforms 12, when connected with the central floating platform 11, form a cross shape. This arrangement ensures that the weight borne by the corner floating platforms 12 during construction can be evenly distributed throughout the overall structure, effectively enhancing the overall stability.

[0044] Furthermore, the corner floating platform 12 includes a corner frame and corner pontoons, with the corner pontoons fixed within the corner frame; the corner frame is connected to the work platform 121 and / or the protective fence 122. This configuration allows the corner floating platform 12 to be further disassembled, reducing the difficulty of transporting components after construction, and enabling construction personnel to directly move the corner floating platform 12 using equipment such as aerial work platforms, reducing the time required for transportation.

[0045] Specifically, the corner frame can adopt a semi-enclosed or fully enclosed frame structure, so that the corner pontoons can be confined within the corner frame, without any specific restrictions.

[0046] Furthermore, the central floating platform 11 includes a central frame and a central pontoon, with the central pontoon fixed to the central frame. The surface of the central frame is provided with screw points, and the first connecting rod 13 is screwed to these screw points. Specifically, the central frame can be a cross-shaped frame, with the central pontoon fixed within the four areas formed by the cross. The central frame is then connected to the first connecting rod 13 via screw points. This design simplifies the structure of the central floating platform 11 to the greatest extent possible, reducing the number of components and the overall weight, and facilitating installation, disassembly, and transportation.

[0047] Furthermore, a lifting ring 16 is provided at the top of the central frame. The lifting ring 16 allows the central frame to be lifted together with the bolted first connecting rod 13, increasing the transportation options after disassembly and improving disassembly and conveying efficiency.

[0048] Please refer to Figures 1 to 4 Embodiment 1 of this utility model is: a floating platform 1 for welding the barrel of a thickener, used for segmented welding inside the thickener, comprising: a central floating platform 11, four sets of corner floating platforms 12, and a first connecting rod 13, the two ends of which are screwed to the corner floating platforms 12 and the central floating platform 11 respectively. After the corner floating platforms 12 are connected to the central floating platform 11, the whole structure forms a cross shape.

[0049] The first link 13 and the second link 14 are two hinged links.

[0050] It also includes a third link 15. Each protective fence 122 is provided with 3 fixed lugs, and each fixed lug is provided with a third link 15. The first link 13 and the second link 14 are provided with screw holes on the side near the corner floating platform 12. One end of the third link 15 is provided with threads. The third link 15 passes through the fixed lug and is screwed into the screw hole.

[0051] It also includes a side fixing mechanism 3, which is used to restrict the position of the corner floats 12 and the central floats 11 inside the thickener. The side fixing mechanism 3 includes a first locking structure 31 and a second locking structure 32. The first locking structure 31 includes a first fixing member 311 and a first connecting member 312. The first fixing member 311 includes a central ring portion 311a and a side diffuser portion 312b. The central ring portion 311a is distributed in a vertical direction, and the side diffuser portion 312b extends from the upper and lower ends of the central ring portion 311a to the left and right sides of the central ring portion 311a. The central ring portion 311a is connected to the barrel 2 of the thickener. One end of the first connecting member 312 is connected to the corner floats 12, and the other end of the first connecting member 312 is connected to the central ring portion 311a. The second locking structure 32 includes a second connector 321. One end of the second connector 321 is provided with an adsorption element 322, which is adsorbed onto the barrel 2 of the thickener. The other end of the second connector 321 is detachably connected to the protective fence 122. The adsorption element 322 is a suction cup.

[0052] Each corner floating platform 12 provides 600 kg of buoyancy, and the central floating platform 11 provides 400 kg of buoyancy.

[0053] In this embodiment, eight first fasteners 311 are welded evenly spaced on the barrel 2 of each thickener.

[0054] In this embodiment, the central floating platform 11 includes a central frame and a central pontoon, with the central pontoon fixed to the central frame; the surface of the central frame is provided with screw points, and the first connecting rod 13 is screwed to the screw points. A lifting ring 16 is provided at the top of the central frame.

[0055] The working principle of this utility model is as follows: During the thickener welding construction, a floating platform for thickener barrel welding is assembled inside the first layer barrel 2. After assembly, water is injected into the barrel 2, and the floating platform rises as a whole. Then, the next layer of barrel 2 is hoisted, and the construction workers perform welding work on four worktables 121. When the welding position needs to be adjusted, the construction workers jointly disconnect the connection between the first connecting piece 312 and the first fixing piece 311, pull off the second connecting piece 321, and then push and pull the barrel 2 through the second connecting piece 321 to make the floating platform rotate as a whole. After the adjustment is completed, the first connecting piece 312 is connected to the first fixing piece 311 in the corresponding position, and the second connecting piece 321 is fixed at the same time. After fixing, the welding construction continues. After each layer of barrel 2 is welded, the first connecting piece 312 is retracted, and then the floating platform is stabilized by inserting and removing the second connecting piece 321. Water is injected again, and the welding process is repeated for the next layer of barrel 2. After welding is completed, the workers on each corner float 12 lift and disassemble the third connecting rod 15, separating the corner float 12 from the first connecting rod 13 or the second connecting rod 14. Then, the second connecting rod 14 and the corner float 12 are moved or lifted away from outside the thickener. At the same time, the workers on one of the corner floats 12 pull the central float 11 with the first connecting rod 13, bringing it closer to the edge of the thickener, and then lift the central float 11 together with the first connecting rod 13 away with the lifting ring 16.

[0056] Although this document uses numerous terms such as floating platform for thickener barrel welding, central floating platform, corner floating platform, worktable, protective fence, first link, second link, third link, lifting ring, barrel, side fixing mechanism, first locking structure, first fixing component, central ring, side diffuser, first connecting component, second locking structure, second connecting component, and adsorption component, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
