Description

Technical Field

[0001] This invention relates to the field of layer wrapping technology, specifically to a weld polishing device for wrapping hydrogen storage tank layers. Background Technology

[0002] Hydrogen storage tanks are commonly used for the centralized transportation of hydrogen. Due to the special physicochemical properties of hydrogen, it is prone to accidents such as deflagration and is classified as a dangerous transport item, requiring extremely high transport standards. This necessitates high rigidity in the hydrogen tanks. To prevent damage from sand and gravel splashes during transport, the hydrogen tanks are wrapped with multiple layers of formed steel plates before leaving the factory. Special clamping or tensioning devices are used to assist in manual welding, improving the tank's rigidity. During the layering process, several problems arise. The elastic deformation caused by the ductility of the steel plates necessitates wrapping and welding. Special clamping mechanisms are required for fixation during welding, and manual or automatic welding is used to form a single weld. The weld surface has pitted characteristics, and the uneven surface of the multiple layers significantly reduces the fit between the upper and lower layers of formed steel plates. Furthermore, the irregular distribution of the welds also reduces the overall integrity of the multi-layered steel plates.

[0003] To achieve the above objectives, the present invention provides a weld polishing device for wrapping hydrogen storage tank layers, which can solve the problems mentioned in the background art. Summary of the Invention

[0004] The present invention adopts the following technical solution:

[0005] A welding polishing device for wrapping hydrogen storage tank shelves includes a support base, an adjustment assembly, and a hydrogen storage tank. The hydrogen storage tank is located above the support base, the adjustment assembly is located on both sides of the support base, and a suspension assembly is connected above the hydrogen storage tank. The suspension assembly is used to wrap and fix the hydrogen tank and shelves.

[0006] The support base includes two straight tracks and a polishing base. The polishing base is connected between the two straight tracks. The upper surface of the polishing base is a concave arc-shaped surface. Multiple through slots are provided on the arc-shaped surface. Two sets of movable polishing boxes are connected in the multiple through slots. Each movable polishing box is provided with multiple evenly spaced abrasive discs. The rotation radii of the multiple abrasive discs do not intersect each other.

[0007] The straight track is equipped with a drive roller, which is in contact with the hydrogen storage tank;

[0008] The surface of the arc-shaped surface is provided with an identification component for identifying the presence of a weld.

[0009] Preferably, each of the straight tracks includes a fixed base and a lifting base. The fixed base has multiple lifting cylinders fixed inside it. The output end of the lifting cylinder extends out of the upper surface of the fixed base and is connected to the bottom of the lifting base. The polishing base is fixedly connected to the fixed base.

[0010] Preferably, the lifting base has a cavity inside and a slot on the top. A drive base is provided inside the slot. Two support frames are connected to the top of the drive base. A drive motor is connected to each of the two support frames. The drive roller is connected to the output end of the drive motor.

[0011] The axes of the two drive rollers are opposite and parallel to the axis of the hydrogen storage tank.

[0012] Preferably, when the lifting base is at its lowest operating position, the highest point of the arc surface is located at the circumferential tangent of the two driving rollers.

[0013] Preferably, the through groove is a long rectangular straight groove, the movable polishing box is provided with rotating columns at both ends, and the two inner walls of the through groove are provided with lifting grooves that cooperate with the rotating columns;

[0014] The polishing base is equipped with a compression cylinder inside. The output end of the compression cylinder is connected to a lifting plate. Multiple movable blocks are provided on both sides of the lifting plate. The upper part of the movable blocks is sleeved around the circumference of the rotating column.

[0015] The lifting groove is a waist-shaped hole groove perpendicular to the ground, and the rotating column is slidably connected to the lifting groove.

[0016] Preferably, the movable polishing box is provided with a plurality of polishing motors at even intervals inside, and the plurality of polishing motors correspond to the plurality of abrasive discs;

[0017] The identification component is located at the lowest horizontal position of the arc-shaped surface, and the two sets of movable polishing boxes are located inside the through slots on both sides of the identification component.

[0018] Preferably, each set of the movable polishing box is connected to at least two of the through slots, and the multiple polishing motors inside the movable polishing box connected to adjacent through slots are arranged in different positions.

[0019] Preferably, a connecting adhesive layer is provided between the movable polishing box and the through groove, and the connecting adhesive layer is wrapped around the periphery of the movable polishing box.

[0020] Preferably, the identification component includes a scanner and a signal processing center, the scanning end of the scanner is vertically upward, the signal processing center is disposed above the extrusion cylinder, and the signal processing center is connected to the scanner.

[0021] Preferably, each side of the identification component is provided with at least two sets of movable polishing boxes, and when the extrusion cylinder is not in the extended state, the horizontal height of the grinding wheel is lower than the surface height of the arc-shaped surface.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] This invention utilizes a polishing base in conjunction with a rotating drive roller. When the support base is not raised, its arc-shaped surface is close to the bottom of the hydrogen storage tank. By rotating the drive roller, the already welded hydrogen storage tank is rotated, bringing the weld seam into the detection range of the identification component. Once the weld seam is detected, the extrusion cylinder and polishing motor are activated to polish the weld seam. This combination of multiple components achieves the following effects: After the welding of the previous-level forming steel plate is completed, the surface of the weld seam of the previous level can be polished during the process of adding the next level after the suspension component is released, solving the problem of low fit between layers due to the bulges of the weld seam; At the same time, after one polishing, the weld seam can be unscrewed for observation. If it is qualified, the next level steel plate can be directly added. At this time, the weld seam is within the observation range, not located at the connection position of the next level steel plate (i.e., the position where the steel plate is inserted into the drive roller), which makes it easier to distribute the weld seam, making the weld seam distribution more uniform and improving the overall integrity of the multi-layer plate welding.

[0024] In addition, the movable connection of the polishing box can adapt to changes in the size and specifications of the hydrogen tank, increasing the functionality of the equipment. During normal time, the position of the grinding wheel is lower than the upper surface of the arc-shaped surface, which can guide the shelf without affecting the insertion of the next shelf. The wrapping and surrounding of the connecting adhesive layer can also adapt to the effects of lifting and angle grinding, enabling non-destructive grinding and improving equipment safety.

[0025] The polishing base reduces the difficulty of installing the next layer, increases the speed of processing steps, and effectively improves productivity while reducing labor costs. Attached Figure Description

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly associated with those skilled in the art to which this invention pertains. The terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] The present invention will be further described in detail below with reference to the accompanying drawings.

[0037] One embodiment of the present invention is as follows, please refer to the supporting bases 1-6 in the accompanying drawings. A weld polishing device for wrapping the hydrogen storage tank shelf includes a supporting base 1, an adjusting component 3 and a hydrogen storage tank 4. The hydrogen storage tank 4 is located above the supporting base 1. The adjusting component 3 is located on both sides of the supporting base 1. A suspension component 2 is connected above the hydrogen storage tank 4. The suspension component 2 is used to wrap and fix the hydrogen tank and the shelf 5.

[0038] The support base 1 includes two straight tracks 103 and a polishing base 110. The polishing base 110 is connected between the two straight tracks 103. The upper surface of the polishing base 110 is a concave arc-shaped surface 122. The arc-shaped surface 122 is provided with multiple through grooves 120. Two sets of movable polishing boxes 111 are connected in the multiple through grooves 120. Each movable polishing box 111 is provided with multiple evenly spaced grinding discs 119. The rotation radii of the multiple grinding discs 119 do not intersect each other. The straight tracks 103 are provided with drive rollers 106, which are in contact with the hydrogen storage tank 4. The surface of the arc-shaped surface 122 is provided with an identification component 121 for identifying the presence of welds.

[0039] Each straight track 103 includes a fixed base 101 and a lifting base 102. A plurality of lifting cylinders 104 are fixed inside the fixed base 101. The output end of the lifting cylinder 104 extends out of the upper surface of the fixed base 101 and is connected to the bottom of the lifting base 102. The polishing base 110 is fixedly connected to the fixed base 101.

[0040] The lifting base 102 has a cavity inside and a slot on the top. A drive base 105 is provided inside the slot. Two support frames 107 are connected to the top of the drive base 105. A drive motor is connected to each of the two support frames 107. The drive roller 106 is connected to the output end of the drive motor.

[0041] The axes of the two drive rollers 106 are opposite and parallel to the axis of the hydrogen storage tank 4; when the lifting base 102 is at its lowest operating position, the highest point of the arc surface 122 is located on the circumferential tangent of the two drive rollers 106.

[0042] The weld polishing friction process of the present invention is divided into the following steps: welding the current weld, releasing the suspension component 2, adjusting the support base 1 and the adjustment component 3 for lifting, the identification component 121 for detection, controlling the polishing motor 117 for polishing, driving the drive roller 106 to rotate the weld to an observable position, performing additional welding and secondary polishing if necessary, and placing the next layer plate 5. During the process, the drive roller 106 is continuously rotated, thus completing the weld polishing of the first layer plate 5. This method can adapt to the weld polishing requirements of multi-layer plates 5, eliminating the need for frequent manual polishing, and completing the welding work in a simple and systematic way. It also separates the upper-level weld from the lower-level weld, improving the safety of multi-layer steel plates. During the weld identification process, the identification component 121 is mainly used to identify the weld. The scanner 115 can be selected to quickly collect the surface information of the weld using a radar sensor. Ordinary radar sensors can accurately collect the surface changes of the layer plate 5 and feed them back to the information processing center to control the start of the grinding motor 117. It is also worth mentioning that the extrusion cylinder 109 and the lifting plate 112 only provide a certain continuous upward thrust to the movable polishing box 111. The extrusion cylinder 109 with a low force limit is sufficient, which will not cause significant damage to the surface of the layer plate 5. This allows the grinding wheel 119 to always be in close contact with the hydrogen storage tank 4, which meets the usage requirements.

[0043] In one embodiment of the present invention:

[0044] Please refer to this carefully. Figure 3-6 The through groove 120 is a long rectangular straight groove, the movable polishing box 111 is provided with rotating columns 114 at both ends, and the two inner walls of the through groove 120 are provided with lifting grooves 108 that cooperate with the rotating columns 114.

[0045] The polishing base 110 is equipped with a compression cylinder 109 inside. The output end of the compression cylinder 109 is connected to a lifting plate 112. Multiple movable blocks 113 are provided on both sides of the lifting plate 112. The upper part of the movable block 113 is sleeved on the periphery of the rotating column 114.

[0046] The lifting groove 108 is a waist-shaped hole groove perpendicular to the ground, and the rotating column 114 is slidably connected to the lifting groove 108.

[0047] The movable polishing box 111 is equipped with a plurality of polishing motors 117 evenly spaced inside, and the plurality of polishing motors 117 correspond to the plurality of abrasive discs 119. The identification component 121 is located at the lowest horizontal position of the arc-shaped surface 122, and the two sets of movable polishing boxes 111 are located inside the through slots 120 on both sides of the identification component 121. Each set of movable polishing boxes 111 is connected to at least two through slots 120, and the plurality of polishing motors 117 inside the movable polishing boxes 111 connected to adjacent through slots 120 are arranged in different positions. A connecting adhesive layer 118 is connected between the movable polishing box 111 and the through slot 120, and the connecting adhesive layer 118 is wrapped around the periphery of the movable polishing box 111. The connecting adhesive layer 118 and the lifting groove 108 can enhance the polishing effect, effectively adapt to the curvature of the hydrogen tank surface and the insertion effect of the next-level layer 5, and effectively improve production efficiency.

[0048] The identification component 121 includes a scanner 115 and a signal processing center 116. The scanning end of the scanner 115 is vertically upward, and the signal processing center 116 is located above the extrusion cylinder 109 and connected to the scanner 115. At least two sets of movable polishing boxes 111 are provided on both sides of the identification component 121. When the extrusion cylinder 109 is not extended, the horizontal plane of the polishing wheel 119 is lower than the surface height of the arc-shaped surface 122. The movable connection of the movable polishing boxes 111 can adapt to changes in the size and specifications of the hydrogen tank, increasing the efficiency of the identification component. The equipment's functions include: during normal operation, the position of the grinding wheel 119 is lower than the upper surface of the arc-shaped surface 122, which guides the layer 5 without affecting the insertion of the next layer 5; the wrapping and surrounding of the connecting adhesive layer 118 can also adapt to the effects of lifting and angle grinding, enabling non-destructive grinding and improving equipment safety; the identification component 121 can scan the weld multiple times and then grind repeatedly until it passes the inspection, automatically pausing and then manually identifying and inserting the next steel plate, so that the upper-level formed steel plate and the lower-level weld position roll and rotate simultaneously, which can appropriately adjust the weld position to prevent overlap.

[0049] The present invention has been described by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
