Description

Technical Field

[0001] This invention relates to the field of tank wrapping equipment technology, specifically a small-scale binding wrapping machine and wrapping method. Background Technology

[0002] Hydrogen storage tanks are the primary capacity carriers for transporting hydrogen, and their safety requirements are high. They require additional steel wrapping to enhance their resilience against impacts during transport and reduce the risk of damage and leakage from external impacts. During the wrapping of small tanks, the outer steel layer, due to its small diameter, exhibits relatively strong elastic potential energy release, making bending and subsequent assembly difficult. This results in a challenging wrapping operation for small tanks, as it's impossible to simultaneously bend and assemble the steel plates while limiting their bending rebound. When using a binding method, this lack of synchronization necessitates frequent and repeated active binding actions. Furthermore, the inability to restrict the diameter and edge distance at the steel plate joints easily leads to misalignment and inaccurate positioning, making the external wrapping of small tanks particularly difficult.

[0003] To achieve the above objectives, the present invention provides a small-sized binding and bandaging machine and a bandaging method, which can solve the problems mentioned in the background art. Summary of the Invention

[0018] Preferably, the steel coil inlet is located on the side of the sub-integration compartment near the conveying group, and the side of the sub-integration compartment near the steel coil inlet is provided with a limiting guide plate and rollers;

[0019] A conveying platform is provided above the conveying group. The conveying platform is used to convey the wrapped steel plate. The roller is installed at a height slightly higher than the height of the conveying platform. The limiting guide plate is used to guide the wrapped steel plate to contact one of the multiple arc-shaped guide plates.

[0020] The inner surfaces of the plurality of limiting guide plates are used to limit the outer diameter of the rolled steel plate.

[0026] The flipping assembly is located at both ends of the hydrogen tank and is used to flip and adjust the position of the external weld seam of the hydrogen tank.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] This invention, by setting up a movable installation group and an adaptive installation group on the side, can realize a series of functions such as opening the cable, filling the new surface layer on the side, and guiding the bending of the guide plane surface layer. This allows the small binding machine to operate continuously to realize the function of continuous binding of multi-layer plates, solving the problems of time-consuming and labor-intensive binding and inaccurate binding positioning caused by the need for repeated binding in traditional steel plate binding.

[0029] This device employs a guided filling method for the lateral filling of the lower layer of wrapping material. The limiting guide plate at the end of the installation assembly, in conjunction with the limiting rear plate, provides edge guidance and positioning. This allows the steel plate to automatically form a curved shape as it is guided into the installation assembly. Once the steel plate is completely within the defined range of the overall limiting guide plate and the limiting rear plate, its other side aligns with the steel coil integration groove on the movable installation assembly. This invention utilizes a connecting, extended, adaptable band design between adjacent steel coil integration grooves. After the steel plate is released from the limiting rear plate and its converging constraint is lifted, the diameter of the steel plate can be reduced simply by manipulating the movable installation assembly. Furthermore, it allows for easier adaptation to the outer wall of the hydrogen tank. This enables rapid completion of the bending process of the next layer of steel plate before the wrapping, welding, and positioning process. The bending and assembly processes are achieved in a near-synchronous manner, simplifying the workflow, improving the automation level of the device, eliminating the need for additional bending operations on the steel coil, and reducing errors.

[0030] This device utilizes a simple and reliable lateral binding and wrapping method, solving the problem of inconvenient binding and welding caused by the large elastic deformation due to the short length of the outer steel cladding for small circular diameter steel tanks. The shorter cladding layer exhibits greater angular rebound force after bending. During untying, the device features multi-directional synchronous unlocking and a cable-opening component to restrict the surface of the upper steel plate, reducing the problem of rapid springback caused by poor welding quality of the upper surface cladding. Furthermore, after the traction cable is opened, the inserted cladding layer maintains a positioning and limiting effect on its arc position throughout the process of guided insertion and increased curvature adaptability. When the positioning and limiting effect ends, the traction cable is also tightened and bound, thus the newly placed outer steel plate lacks the conditions and stroke for elastic deformation release. These beneficial effects make the device more adaptable to small steel tank binding operations, and allow for a wider range of toughness ranges for the outer cladding material, making it more suitable for shorter diameter steel layers (smaller diameter hydrogen tanks) of the same material.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0053] The present invention will be further described in detail below with reference to the accompanying drawings.

[0054] In one embodiment of the present invention: please refer to the appendix for details. Figure 1-8 The system includes a hydraulic binding platform 1, a shelf mounting group 2, and a tilting group 3. The hydraulic binding platform 1 is equipped with two sets of hydraulic groups 101 and a hydrogen tank 5. The far ends of the two sets of hydraulic groups 101 are connected to multiple sets of traction steel cables 107. The traction steel cables 107 are coiled and wrapped around the outer wall of the hydrogen tank 5. The cables between the two sets of hydraulic binding platforms 1 are interconnected, and the cables are moved and tightened by the extension and retraction of the cylinder.

[0055] The shelf mounting group 2 includes a movable mounting group 201 and an adaptive mounting group 202, wherein the movable mounting group 201 and the adaptive mounting group 202 are located at opposite ends of the hydrogen tank 5.

[0056] The movable installation assembly 201 is internally equipped with a cable-opening component 203, which includes an internal drive disk 204 and a main integration compartment 221. The central axis of the internal drive disk 204 is aligned with the central axis of the hydrogen tank 5 and the adaptation installation assembly 202. The internal drive disk 204 can be fixed at the rear end of one side of the main integration compartment 221; its exterior can also be equipped with... Figure 5 The motor shown adjusts the angle of the entire inner drive disc 204 to facilitate the steel coil inlet 222 on one side;

[0057] The inner drive disk 204 extends outward from the center and is connected to an outer extension block 214. A telescopic shovel plate 211 is connected to one side of the outer extension block 214. One end of the shovel plate 211 extends toward the adaptive mounting group 202 and is locked to the adaptive mounting group 202. When multiple shovel plates 211 are extended, they are located between the outer wall of the hydrogen tank 5 and the traction cable 107.

[0058] The adaptable installation group 202 is provided with a conveying group 4 on one side, the conveying group 4 is used to convey the wrapping steel plate 7, and the adaptable installation group 202 is provided with a steel coil inlet 222 on one side for guiding the wrapping steel plate 7.

[0059] The adaptive installation assembly 202 is provided with a limiting group inside. The limiting group is used to guide the wrapping steel plate 7 to form a bend and to limit the wrapping steel plate 7 in an arc shape. After the limiting is completed, the arc-shaped wrapping steel plate 7 is located on the periphery of the hydrogen tank body 5.

[0060] This device, through the lateral arrangement of the movable mounting group 201 and the adaptive mounting group 202, can achieve a series of functions such as opening the cable, lateral filling of the new surface layer, and guiding the bending of the guide plane surface layer. This allows the small binding machine to operate continuously, realizing the function of continuous binding of multiple layers of plates. It solves the problems of time-consuming, labor-intensive, and inaccurate binding positioning caused by the need for repeated binding of traditional steel plate binding. The device uses guided filling for the lateral filling of the lower layer of wrapped plate. The limiting guide plate 234 at the end of the adaptive mounting group 202 works with the limiting rear plate 6 to guide and position the edge. This allows the steel plate 7 to automatically form a curved plate shape during the process of being guided into the adaptive mounting group 202. After the steel plate 7 is completely within the limited range outside the overall limiting guide plate 234 and the limiting rear plate 6, its other side is connected to the steel coil integration groove 215 on the movable mounting group 201.

[0061] Please refer to this carefully. Figure 5-11The drive end of the drive motor 205 is located inside the inner drive disk 204 and is connected to the drive gear 212. The inner drive disk 204 has a driven gear disk 213 at the internal axis position, and the drive gear 212 and the driven gear disk 213 mesh with each other.

[0062] The driven gear disk 213 is provided with a plurality of arc-shaped outwardly expanding rails 207 extending from the inside of the disk to the outside. The inner drive disk 204 is provided with a plurality of guide rails 206. Each guide rail 206 is provided with a cable opening rod 208. The end of the cable opening rod 208 near the driven gear disk 213 is provided with a guide post 209. The guide post 209 is connected to the outwardly expanding rails 207.

[0063] The external expansion block 214 is connected to one end of the cable release rod 208. The multiple external expansion blocks 214 form a segmented annular shape with the same center as the inner drive disk 204. The shovel plate 211 is fixed to the outer circumferential side of the external expansion block 214. The outward expansion spline connection expansion method can ensure the synchronization of the push-out. The internal guide rails 206 are distributed in a ring about the center position of the gear disk. The distance difference between the two arc apexes and the center position of the gear disk is the push-out range of the external expansion block.

[0064] Please refer to this carefully. Figure 5-8 A cable-opening cylinder 210 is fixed to the outside of a single external extension block 214. One protruding end of the cable-opening cylinder 210 extends toward the adaptive mounting assembly 202. The shovel plate 211 is fixed to the protruding end of the cable-opening cylinder 210. A locking block 225 is provided on the top of the shovel plate 211. The locking block 225 is fixed to the adaptive mounting assembly 202 when extended. A locking groove 233 is provided on the limiting assembly. The locking groove is fixedly locked to the locking block 225. The length of the cable-opening cylinder 210 is not limited to... Figure 6 The length shown can be a long-distance cylinder arranged on one side of the main integration compartment 221. The length is sufficient to meet the requirement of lifting the steel cable on the surface of the tank. The shovel plate 211 is used to shovel the steel cable on the surface of the tank. The locking block 225 is connected to the limit group and can drive the outward expansion and inward contraction movements at equal intervals and times to the movements on the adaptation installation group 202, which can facilitate the subsequent translation and docking of the steel layer on both sides.

[0065] Please refer to this carefully. Figure 5-11The depth of the internal steel coil integration groove 215 inside the external expansion block 214 is not limited. One side of its surface is adapted to the installation group 202 with an adaptive length to adapt to the position of the conveying group 4. In addition, the aforementioned arc-shaped guide plate 220 and arc-shaped guide plate 235 can be connected synchronously or separately synchronously. Another way is to synchronously set the inlet only inside the movable installation group 201. When the steel coil moves to the movable installation group 201 on one side, it directly docks into the steel coil integration groove 215. The design of the arc-shaped guide plate 220 can still prevent the steel coil at the edge position from being squeezed out of the steel coil integration groove 215 within the limited position range during the process of retracting the thickness of the external expansion block 214.

[0066] In yet another embodiment of the invention: please refer to... Figure 1-3 , Figure 5-8 Figure 11 The adaptive installation group 202 includes a secondary integrated compartment 230, and a recovery seat 231 is provided at one end of a plurality of limiting groups. The inner surface of the secondary integrated compartment 230 is tubular. The recovery seats 231 are evenly spaced about the center of the secondary integrated compartment 230. A mating block 232 is provided at one end of the recovery seat 231. The mating block 232 is fixed to the shovel plate 211.

[0067] The other end of the mating block 232 is provided with an arc-shaped limiting guide plate 234, and the axial center positions of the multiple limiting guide plates 234 are the same. An arc-shaped guide plate 235 is provided on one side of the limiting guide plate 234.

[0068] The steel coil inlet 222 is located on the side of the sub-integration compartment 230 near the conveying group 4. The sub-integration compartment 230 is provided with a limiting guide plate 223 and a roller 224 on the side near the steel coil inlet 222.

[0069] The conveying group 4 is provided with a conveying platform 401 above it. The conveying platform 401 is used to convey the wrapped steel plate 7. The roller 224 is installed at a height slightly higher than the height of the conveying platform 401. The limiting guide plate 223 is used to guide the wrapped steel plate 7 to contact one of the multiple arc-shaped guide plates 235.

[0070] The inner surfaces of the plurality of limiting guide plates 234 are used to limit the outer diameter of the rolled steel plate 7;

[0071] The thickness of the limiting guide plate 234 and the arc-shaped guide plate 235 in the direction of the tank axis is not limited. They are mainly used to accommodate the thickness of the sub-integration compartment 230. At the same time, the longer they are, the larger the coverage area of ​​the edge of the steel coil can be. They can provide better support for the steel coil during the movement when the steel coil is moved to the side of the movable installation group 201. The entire installation group 202 can move actively or can be separated from the lateral limiting rear plate 6 by a certain distance. The internal movement is synchronized with the movement of the movable installation group 201 through the connection of the locking block 225.

[0072] Please refer to this carefully. Figure 1-3 The limiting rear plate 6 is a cylindrical structure, and the axis of the limiting rear plate 6 is located on the same axis as the axis of the adaptive installation group 202; the limiting rear plate 6 is used to limit the inner diameter of the rolled steel plate 7, and the diameter of the limiting rear plate 6 is smaller than the maximum inner diameter of the adaptive installation group 202.

[0073] Please refer to this carefully. Figure 1-3 , Figure 7-10 The outer expansion block 214 has a steel coil integration groove 215 inside that contacts the side of the wrapping steel plate 7. The outer expansion block 214 has an interconnected integration inner groove 216 and a mating side groove 227 inside. The integration inner groove 216 has a winding column 217 inside. An extension adapting strip 218 is wound on the winding column 217. One end of the steel coil integration groove 215 has an extension adapting strip 218. The extension adapting strip 218 extends out from the mating side groove 227 and is fixed to the chamfered opening 219 of the next outer expansion block 214.

[0074] One of the external expansion blocks 214 is provided with an arc-shaped guide plate 220 on its exterior, which is used to guide the wrapping steel plate 7 into the steel coil integration groove 215.

[0075] The hydraulic assembly 101 includes a lateral mounting base 102 fixed on the hydraulic binding platform 1. A hydraulic cylinder 103 is fixed on the lateral mounting base 102. A secondary traction assembly 104 is provided at the extended end of the hydraulic cylinder 103. Two connecting rods are movably connected to both sides of the secondary traction assembly 104. A secondary traction wheel 105 is provided at one end of each connecting rod. A lateral positioning wheel 106 is fixed at both ends of the hydraulic binding platform 1. The secondary traction wheel 105 corresponds one-to-one with the lateral positioning wheel 106. One end of the traction cable 107 is connected to the secondary traction wheel 105.

[0076] The bottom of the hydraulic binding platform 1 is provided with a drive wheel set 109 and connected to a travel rail 108. The travel direction of the travel rail 108 is parallel to that of the hydrogen tank 5.

[0077] The flipping group 3 is distributed at both ends of the hydrogen tank 5 and is used to flip and adjust the position of the external weld of the hydrogen tank 5.

[0078] In one embodiment of the present invention: a small-sized binding bandaging machine and bandaging method, comprising the following steps:

[0079] S1. Untying the cable: After the welding of the previous steel plate 7 is completed, untie the cylinder on the hydraulic binding platform 1 to release the binding state of the traction steel cable 107 on the outside of the wrapped steel plate 7. At this time, the hydraulic assembly 101 is in an active connection state and moves with it.

[0080] S2, Support cable: Release the support of the flipping group 3, move the layer plate mounting group 2 to contact the wrapping steel plate 7, the cable opening assembly 203 is in the open state, drive the drive motor 205 to make the movable mounting group 201 lock inward until the shovel plate 211 is close to the surface of the hydraulic binding platform 1, start the cylinder to drive the shovel plate 211 to move and lock with the adaptation mounting group 202, and then reverse the drive motor 205 to open the traction steel cable 107 outside the wrapping steel plate 7;

[0081] S3. Conveying new sheet material: Fix one side of the wrapped steel plate 7 to the outer circle of the limiting rear plate 6, and guide the other side into the adaptable installation group 202 along the limiting group to bend the wrapped steel plate 7. After bending, push the limiting rear plate 6 to make the wrapped steel plate 7 move towards the movable installation group 201 until it contacts the movable installation group 201 and is limited. Then retract the limiting rear plate 6.

[0082] S4. New plate wrapping: Start the drive motor 205 to retract each shovel plate. The diameter of the wrapping steel plate 7 is restricted to shrink along with the diameter of the movable installation group 201 until the shovel plate 211 contacts the outer wall of the hydrogen tank 5. The unlocking block 225 is connected to the adaptive installation group 202.

[0083] S5. Cable Retraction: Drive hydraulic unit 101 to pull the cable and slowly tighten it. At the same time, drive cylinder to retract locking block 225 until locking block 225 is fully retracted and the traction cable 107 locks the new layer of steel plate 7 on the outer wall of hydrogen tank 5. Move the movable layer plate installation group 2 away from both ends of hydrogen tank 5, flip up the flipping group 3 to support the outer wall of hydrogen tank 5, and weld the joint of the tightened steel plate 7. After welding, manually trim it, and repeat steps S1-S5 to bind the next layer of steel plate 7. During the rolling process, the device employs a guided filling method for the lateral filling of the lower layer of wrapping material. The limiting guide plate 234 at the end of the adaptable installation group 202, in conjunction with the limiting rear plate 6, provides edge guidance and positioning. This allows the steel plate 7 to automatically form a curved, arc-shaped material as it is guided into the adaptable installation group 202. After the steel plate 7 is completely within the defined range of the overall limiting guide plate 234 and the limiting rear plate 6, its other side aligns with the steel coil integration groove 215 on the movable installation group 201.

[0084] This method utilizes the design of a connecting extension and adaptation band 218 between adjacent steel coil integration grooves 215, coupled with a synchronous opening and closing method in all directions. This allows the steel plate 7 to be reduced in diameter by simply manipulating the movable installation group 201 after the limit plate 6 is released and the steel plate 7 is converging and limited. It can also more easily adapt to the outer wall of the hydrogen tank 5 and quickly complete the bending process of the next layer of steel plate 7 before the wrapping, welding and positioning process. This makes the bending process and the assembly process almost synchronous, which simplifies the workflow, improves the automation level of the device, eliminates the need for additional bending operations on the steel coil, and reduces the generation of errors.

[0085] This device utilizes a simple and reliable lateral binding and wrapping method to solve the problem of inconvenient wrapping and welding caused by the large elastic deformation due to the short length of the outer steel cladding of small circular diameter steel tanks. The shorter steel cladding layer has a larger angular rebound force after bending. This device unlocks simultaneously in multiple directions when untying the ropes. In addition, a rope untying component 203 is provided to restrict the surface of the upper steel plate 7, reducing the problem of rapid spring-off caused by poor welding quality of the upper surface steel cladding. Furthermore, after the traction steel cable 107 is opened, the inserted steel cladding has a positioning and restriction effect on its arc position during the process of guided insertion and increased curvature adaptability. When the positioning and restriction ends, the position of the traction steel cable 107 is also tightened and bound. As a result, the newly placed outer steel plate 7 does not have the conditions and stroke for elastic deformation release. The above beneficial effects make this device more adaptable to the operation of binding small steel tanks. At the same time, the toughness range of the selected material for the outer steel cladding can be wider, making it more adaptable to shorter diameter steel layers of the same material (smaller diameter hydrogen tank 5).
