Description

Technical Field

[0001] This application relates to the technical field of floating roof tank processing, and more particularly to a device for processing a fully liquid-contact floating roof tank. Background Technology

[0002] Floating box units can be divided into two categories based on specifications: standard boxes and non-standard boxes. Standard boxes constitute the core body of the floating roof, for example, a box with dimensions of 3000×500 mm. Given that most petrochemical raw material storage tanks currently adopt a cylindrical design, the floating roof, acting as the "cover" of the tank, is also designed to be circular. Therefore, non-standard floating box units have emerged. These floating boxes do not have a unified standard in specifications; instead, they are customized according to the diameter of the storage tank to which the floating roof is compatible, and are assembled together to form a complete circular floating roof.

[0003] In the existing welding process for the standard floating roof unit panels, the bent semi-finished box body must first be firmly clamped, and then the vertical sides of the box body are welded. However, since the standard box body has uniform dimensions, workers need to repeatedly perform the same clamping and limiting operations, which affects the overall efficiency. Summary of the Invention

[0004] This application aims to at least partially address one of the technical problems in the related art.

[0005] Therefore, one objective of this application is to provide a fully liquid-contact internal floating roof tank processing device that can realize the loading, positioning and unloading of standard tanks of the same size, thereby greatly improving the welding processing efficiency.

[0017] 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 intended to explain this application, and should not be construed as limiting this application.

[0018] The following describes the fully liquid-contact internal floating roof tank processing apparatus according to an embodiment of this application, with reference to the accompanying drawings.

[0019] like Figures 1-6 As shown, the fully liquid-contact internal floating roof tank processing device of this application embodiment may include a conveying mechanism (not shown in the figure) and a positioning mechanism (not shown in the figure).

[0020] The conveying mechanism may include an active module (not shown in the figure) and four driven modules 12 evenly distributed around the active module. Each driven module 12 may include two side plates 121 and multiple rollers 122. The rollers 122 are higher than the side plates 121. The multiple rollers 122 are arranged side by side, and each roller 122 is movably disposed between two side plates 121. Two driven modules 12 located on the same straight line are designated as the X direction, and the other two driven modules 12 are designated as the Y direction.

[0021] The active module may include a base 111, a steering assembly 112, a drive assembly 113, and multiple conveying units 114. The multiple conveying units 114 are disposed on the base 111 and connected to the steering assembly 112 and the drive assembly 113. Each conveying unit 114 may include a conveying roller 1141, a disc base 1142, two upright plates 1143, an inner shaft 1144, and an outer ring 1145.

[0022] The base 111 has a cavity 1111 inside. The lower side of the disc base 1142 movably passes through the base 111 and is movably disposed within the cavity 1111. The disc base 1142 has a vertically arranged through hole 11421 in the middle. Two upright plates 1143 are respectively disposed on the top sides of the disc base 1142, and the conveying roller 1141 is disposed between the two upright plates 1143. The inner shaft 1144 movably passes through the through hole 11421, and a first bevel gear 32 is fixedly disposed at the upper end of the inner shaft 1144.

[0023] A linkage shaft 30 is movably mounted on one of the vertical plates 1143. A second bevel gear 33 is fixedly mounted on one end of the linkage shaft 30, and the second bevel gear 33 meshes with a first bevel gear 32. A belt 31 is fitted onto the outer side of the conveyor roller 1141 at the other end of the linkage shaft 30. The lower end of the inner shaft 1144 is connected to the drive assembly 113. An outer ring 1145 is fixedly fitted onto the lower side of the disc base 1142 and is connected to the steering assembly 112.

[0024] The positioning mechanism may include two symmetrically arranged positioning modules 21. The two positioning modules 21 are respectively located outside the two driven modules 12 in the Y direction, and the two driven modules 12 located in the X direction are used to assist the housing 50 in loading and unloading operations. Each positioning module 21 may include an outer positioning member 211 and an inner positioning member 212. The outer positioning member 211 may include an outer support 2111 and a plurality of positioning side rollers 2112, wherein the two outer supports 2111 on the same positioning module 21 are arranged on the same straight line.

[0025] Multiple positioning side rollers 2112 are provided on the corresponding side plates 121 located in the Y direction. The positioning side rollers 2112 are arranged vertically, and the rotating rollers 122 are arranged horizontally.

[0026] In this embodiment, the multiple conveying rollers 1141 on the active module can actively convey the box 50, while the rotating roller 122 and the positioning side roller 2112 on the driven module 12 are unpowered rollers. The rotating roller 122 and the positioning side roller 2112 play a role in positioning the box 50 during the conveying process.

[0027] The inner positioning element 212 is L-shaped, and both inner positioning elements 212 on the same positioning module 21 are connected to the adjustment mechanism 40.

[0028] It should be noted that the adjustment mechanism 40 described in this embodiment has the function of controlling the two inner positioning members 212 connected thereto to move synchronously, so that the two inner positioning members 212 can simultaneously fit and separate from the corresponding inner wall of the box 50.

[0029] Specifically, the adjustment mechanism 40 may include a lifting frame 41, a top plate 42, a first moving component 43, and a moving frame 44. The lifting frame 41 may be a vertically arranged pneumatic rod, and the height of the lifting frame 41 is adjustable. The top plate 42 is located on the top of the lifting frame 41, and two sliding holes 421 are symmetrically arranged on the top plate 42. The two sliding holes 421 are arranged in a figure-eight shape. The moving frame 44 is movably arranged on the top plate 42 through the first moving component 43. Each inner positioning component 212 has a slider 2121 on its top. The two corresponding sliders 2121 pass through the corresponding sliding holes 421 in sequence and are slidably arranged inside the moving frame 44.

[0030] It should be noted that the positioning module 21 described in this embodiment can clamp and limit the two vertical edges on one side of the housing 50.

[0031] Specifically, the two outer supports 2111, the positioning side rollers 2112 on both sides, and the multiple rotating rollers 122 at the bottom work together to effectively limit the outer side of the housing 50. Meanwhile, the two inner positioning elements 212 act at the two inner corners of the housing 50, cooperating with the outer supports 2111 and the positioning side rollers 2112 to stably clamp the three sides of the housing 50. This design allows the two vertical edges of the housing 50 to abut tightly, facilitating convenient welding operations on these two vertical edges.

[0032] Steering assembly 112 and drive assembly 113 are respectively disposed in cavity 1111, and steering assembly 112 and drive assembly 113 are arranged vertically. Steering assembly 112 may include second moving part 1121 and multiple racks 1122 disposed at the output end of second moving part 1121. Each outer ring 1145 has a tooth structure 11451 on its outer side, and the tooth structure 11451 meshes with the corresponding rack 1122.

[0033] It should be noted that the first moving component 43 and the second moving component 1121 described in this embodiment can both be cylinders, telescopic motors, etc. The first moving component 43 has the function of controlling the linear movement of the moving frame 44 connected to it. Under the action of the moving frame 44 and the two corresponding sliding holes 421 and sliders 2121, the two corresponding inner positioning members 212 can move synchronously to achieve precise positioning. The second moving component 1121 has the function of controlling the linear movement of multiple racks 1122 connected to it. The multiple racks 1122 can thus drive multiple outer rings 1145 to rotate synchronously through the gear tooth structure 11451, thereby realizing the steering adjustment of multiple conveying rollers 1141.

[0034] In this embodiment, during the steering adjustment of the conveyor roller 1141, the rotation of the outer ring 1145 synchronously drives the corresponding disc base 1142, upright plate 1143, conveyor roller 1141, and linkage shaft 30 to rotate. At this time, the second bevel gear 33 on the linkage shaft 30 rotates around the first bevel gear 32, while the first bevel gear 32 remains stationary. The first bevel gear 32 drives the conveyor roller 1141 to rotate via the linkage shaft 30 and belt 31, ensuring smooth steering adjustment. The steering assembly 112 and the drive assembly 113 cannot operate simultaneously.

[0035] The drive assembly 113 may include a drive component 1131, a timing belt 1132, and a plurality of timing pulleys 1133. The plurality of timing pulleys 1133 are movably disposed within the cavity 1111, and each timing pulley 1133 corresponds one-to-one with the inner shaft 1144 and the two are fixedly connected. The timing belt 1132 is connected to the plurality of timing pulleys 1133, and the drive component 1131 is connected to one of the timing pulleys 1133.

[0036] It should be noted that the driving component 1131 described in this embodiment can be a motor. The driving component 1131 has the function of driving the synchronous pulley 1133 connected to it to rotate. When the synchronous pulley 1133 rotates, under the action of the synchronous belt 1132, multiple synchronous pulleys 1133 will rotate synchronously, thereby driving multiple conveying rollers 1141 to rotate synchronously, realizing active conveying of the box 50.

[0037] As one possible scenario, refer to Figure 6 The length of the roller 122 in the X direction is greater than that in the Y direction, thus better adapting to the conveying requirements of the rectangular box 50.

[0038] Specifically, when welding is required on the bent box 50, the personnel first place the box 50 on a driven module 12 located in the X direction. Then, the box 50 can be manually pushed to move onto multiple conveyor rollers 1141 to complete the loading operation of the box 50.

[0039] Next, personnel adjust multiple conveyor rollers 1141 by 90 degrees using the steering assembly 112, making the conveyor rollers 1141 parallel to the rotating rollers 122 in the Y direction. Then, the drive assembly 113 controls the rotation of the multiple conveyor rollers 1141, conveying the box 50 to the positioning module 21 on one side. During this process, the corresponding positioning side rollers 2112 contact both sides of the box 50 and assist in its conveying. After the box 50 contacts the two outer supports 2111, personnel adjust the top plate 42 downwards using the lifting frame 41, allowing the two inner positioning components 212 to enter the box 50. Then, the first moving component 43 controls the linear movement of the connected moving frame 44, causing the two inner positioning components 212 to simultaneously conform to the corresponding inner walls of the box 50. Under the combined action of the two outer supports 2111 and the positioning side rollers 2112 on both sides, the box 50 is clamped and limited on one side. At this point, relevant personnel can perform welding operations on the two vertical edges of the box 50.

[0040] After the two vertical edges on one side of the housing 50 are welded, the relevant personnel can manipulate the two inner positioning parts 212 to move and separate from the housing 50, and make them exit upward and reset from inside the housing 50. Then, the housing 50 is conveyed to another positioning module 21 by multiple conveying rollers 1141, and the above operation process is repeated to weld the other two vertical edges of the housing 50.

[0041] Finally, personnel use multiple conveyor rollers 1141 to transport the box 50 to the middle position between the two positioning modules 21. Next, the direction of the multiple conveyor rollers 1141 is adjusted again by the steering assembly 112 so that the conveyor rollers 1141 are parallel to the rotating roller 122 in the X direction. Then, the multiple conveyor rollers 1141 are used to transport the box 50 onto another driven module 12, completing the unloading operation of the box 50.

[0042] In summary, the fully liquid-contact internal floating roof tank processing device of this application embodiment can realize the loading, positioning and unloading operations of standard tanks of the same size, thereby greatly improving the welding processing efficiency.
