Detailed Implementation

[0026] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0027] Today, welding technology is widely used in various industries and fields of actual production and manufacturing. The welding process requires welding materials such as welding rods, welding wires, and fluxes, and the level of transportation and management of these materials directly affects production efficiency and welding quality.

[0028] Currently, after welding workers retrieve the required welding materials from the welding material warehouse, they must transport the materials to the work site using trolleys, handcarts, or purely manual labor. On the one hand, the variety of welding materials presents problems during transportation, such as materials easily falling off, being misclassified, and being inconvenient to use. On the other hand, the packaging waste, welding rod residue, and welding wire ends generated from disassembling and assembling welding materials require multiple handling operations, further increasing the labor intensity of the workers. Furthermore, in the welding of large structural components such as wind turbine towers, the amount of welding materials is substantial, and the existing handling methods suffer from small single-load capacity and low transportation efficiency, seriously affecting the overall progress and safety of the welding operation.

[0029] This application provides a welding material transport trolley, wherein the main body of the trolley has a storage component, in which welding materials can be placed. This solves the problems existing in the transportation of welding materials, such as small single-transport capacity, time-consuming and labor-intensive transportation process, welding materials being easy to fall during transportation, welding materials not being able to be neatly classified and placed, great inconvenience when picking them up, and the inability to dispose of welding material disassembly and assembly waste.

[0030] The following describes the welding material transport trolley 100 provided in this application, in conjunction with... Figure 1 .

[0031] The welding material transport trolley 100 provided in this application includes a trolley body 1 and storage components 2. The trolley body 1 has a bearing surface 10; there are multiple storage components 2, all of which are disposed on the bearing surface 10, and at least some of the multiple storage components 2 are used to store different types of welding materials.

[0032] The trolley body 1 includes a main structure and a moving structure. The main structure can be the main frame 11 described below, and the moving structure can be the walking device 12 described below. The main structure includes reinforcing ribs and support plates. The support plates can form a bearing surface 10, and the upper part of the bearing surface 10 is connected to the storage component 2, thus supporting the storage component 2. In addition, the reinforcing ribs can strengthen the support plates and further enhance their load-bearing capacity.

[0033] The main structure's support plate is connected to a movable structure at its lower part. The movable structure supports the support plate, which in turn supports the main structure, thus supporting the storage component 2. The number of movable structures can be four or six, but is not limited to these. It can be understood that the load on the storage component 2 is sequentially transmitted through the support plate of the main structure, then to the movable structure, and finally to the ground. This enables the welding material transport trolley 100 to fulfill its load-bearing function.

[0034] Furthermore, the movable structure of the main body 1 enables the welding material transport cart 100 to perform mobile transportation functions. The wheels of this movable structure include straight wheels, Mecanum wheels, omnidirectional wheels, ball wheels, caster wheels, and steering wheels. Straight wheels can only travel straight along the tangent of the wheel's outer circumference, lacking steering and lateral movement capabilities. Mecanum wheels consist of a hub and rollers arranged at 45° angles, enabling omnidirectional movement, such as translation and rotation in place, suitable for confined spaces, but with weak load capacity, high cost, and requiring structured ground. Omnidirectional wheels are similar to Mecanum wheels, but the angle between the roller axis and the hub axis is 90°, offering similar functions but also subject to load and terrain limitations. Ball wheels enable omnidirectional movement but have limited load capacity, primarily used in light-load scenarios. Caster wheels allow 360° rotation, are mostly made of polyurethane or nylon, and some heavy-duty models are equipped with brakes.

[0035] The main body 1 of the vehicle is made of materials such as aluminum alloy, stainless steel, and high-strength steel, and can be made of one, two, or more materials. The storage component 2 is also made of materials such as aluminum alloy, stainless steel, and high-strength steel, and can be made of one, two, or more materials. Aluminum alloy has a low density, is lightweight, and has good plasticity; stainless steel has a long service life, is durable, easy to clean, and always looks new; high-strength steel can withstand high stress and has good weldability and formability. Since the support plate of the main structure bears a large load, high-strength steel can be used as the material. The storage component 2 can be made of either aluminum alloy or stainless steel. Aluminum alloy is lighter, and stainless steel storage components are easier to clean and have lower manufacturing costs than high-strength steel.

[0036] Optionally, a dedicated storage component 2 can be designed for different welding materials. Through finite element analysis of the load distribution, the load-bearing distribution of storage component 2 can be optimized to improve stability. It also integrates waste collection functionality and incorporates ergonomic design to enhance ease of operation. Finite element analysis refers to simulating a real physical system, such as its geometry and load conditions, using mathematical approximation methods. By using simple yet interacting elements, a finite number of unknowns can approximate the real system. For example, finite element software such as ANSYS and ABAQUS can be used for simulation analysis.

[0037] Among them, there are multiple storage units 2, which can store different types of welding materials, such as flux, welding wire, welding rod, and waste. By centrally setting multiple storage units 2 on the bearing surface 10 of the trolley body 1, different types of welding materials can be classified and stored, avoiding problems such as welding materials falling, improper handling, and confusion. At the same time, by increasing the size of the storage units 2, the problem of small single transport volume of the welding material transport trolley 100 can be solved, thereby improving the efficiency of welding material transport.

[0038] The welding material transport cart 100 provided in this application, through modular, categorized, and functionally integrated design, constructs a tool specifically for transporting welding materials, solving the problems of chaotic classification, unstable fixing, small loading capacity, and inefficient waste disposal existing in the prior art. Based on the physical characteristics of welding materials, such as the need for heat preservation of flux, the classification of welding wire by specifications, and the classification of split and unsplit welding rods, this application combines the actual needs of welding operation scenarios, such as efficient transportation, rapid retrieval, and secure fixing, to achieve classified storage, stable transportation, and centralized waste disposal of welding materials through the structural design of the storage component 2. Simultaneously, dedicated storage components 2 are designed for different welding materials, optimizing the load-bearing distribution to improve stability, integrating waste collection functions, and incorporating ergonomic design to enhance operational convenience, thus achieving full-process optimization of welding material transportation.

[0039] In some embodiments, the plurality of storage components 2 include a first storage container 20, a storage column 21, and a second storage container 22. The first storage container 20 is used to hold flux; the storage column 21 is used to hold welding wire; and the second storage container 22 is used to hold welding rods. The first storage container 20, the second storage container 22, and the storage column 21 are fixedly connected to the main frame 11. The main frame 11 is a component of the trolley body 1.

[0040] The first storage container 20 and the second storage container 22 have shapes including square, rectangular, and circular structures, and are cylindrical structures with a receiving cavity. At least one of these shapes can be selected as the shape structure of the first storage container 20 and the second storage container 22. The storage column 21 includes square columns and cylindrical columns, and the shape structure of the storage column 21 can be a cylindrical structure.

[0041] The storage column 21 is used to hold the welding wire. This can be understood as the welding wire being coiled with a circular hole at its center, which can accommodate the storage column 21. This secures the welding wire and prevents it from falling out during transport.

[0042] Alternatively, the storage column 21 can be designed as an adjustable tilt angle and height storage column. Specifically, the storage column 21 includes a slide rail adjustment rod and a tilt angle locking mechanism. The slide rail adjustment rod is used to adjust the height of the storage column 21, and the tilt angle locking mechanism is used to adjust the angle between the storage column 21 and the bearing surface 10 of the trolley body 1. In this way, welding wires of different specifications can be accurately embedded, avoiding tipping problems caused by size mismatch during transportation, while optimizing space utilization.

[0043] The flux is placed in the first storage container 20, and the welding rod is placed in the second storage container 22. By classifying and placing them, the welding materials can be arranged in a more orderly and reasonable manner, avoiding problems such as messy placement of welding rods and flux and inconvenience when taking them out during welding operations.

[0044] The main frame 11 has better support function. Therefore, by fixing the first storage container 20, the second storage container 22, and the storage column 21 to the main frame 11, the first storage container 20, the second storage container 22, and the storage column 21 can be fixed more stably.

[0045] In this way, through modular and categorized storage structure design, flux, welding wire, and welding rod are stored in separate partitions, avoiding the problem of confusion in retrieval caused by mixing welding materials in traditional tools.

[0046] In some embodiments, the welding wire is in the form of a disc and is fitted onto the storage column 21. This can be understood as the disc-shaped welding wire having a central hole for installation; fitting the central hole of the welding wire onto the storage column 21 secures the welding wire. Multiple storage columns 21 can be used to store multiple discs of welding wire, thus increasing the loading capacity per transport. Furthermore, the symmetrical design better balances the load distribution on the welding material transport trolley 100, ensuring stable operation. This not only prevents tipping but also makes retrieval more convenient.

[0047] Optionally, the welding wire storage column 21 can be designed according to the size of the center hole, which can not only increase the number of storage columns 21, but also design different sizes of storage columns 21 to realize the classified storage of welding wires of different specifications.

[0048] In some embodiments, the first storage container 20 is cylindrical, and there are multiple second storage containers 22. The first storage container 20 is used to store flux, and the second storage area is used to store welding rods. The first storage container 20 is cylindrical to better accommodate the insulation container, and the size of the first storage area is designed according to the size of the insulation container. The flux can be a granular material, and it needs to be dried before use and then kept warm in the insulation container after drying.

[0049] Thus, the circular design of the first storage container 20 matches the size of the insulated barrel, ensuring the stability of the insulated barrel during transportation and also achieving the function of heat preservation for the welding flux.

[0050] The second storage container 22 consists of multiple containers that can store welding rods of different types and sizes; they can also store welding rods before and after disassembly separately. This facilitates the classification and placement of welding rods, avoids confusion and improper placement, and makes them easy to retrieve later.

[0051] In some embodiments, the second storage container 22 includes a first sub-container 22a and a second sub-container 22b. The first sub-container 22a is used to store split welding rods; the second sub-container 22b is used to store unsplit welding rods, and the second sub-container 22b and the first sub-container 22a are arranged adjacent to each other. Since the packaging structure of the welding rods before splitting is different from the structure of the welding rods after splitting, the second storage container 22 has a first sub-container 22a and a second sub-container 22b, respectively used to store welding rods before and after splitting.

[0052] The first sub-container 22a and the second sub-container 22b are arranged adjacently because they have the same function: storing welding rods. The adjacent arrangement of the first sub-container 22a and the second sub-container 22b makes it easier to identify and distinguish the first storage container 20 used to hold welding flux.

[0053] In this way, welding electrodes can be categorized, avoiding confusion between different electrodes, and making them easy to retrieve later.

[0054] In some embodiments, the first sub-container 22a is disposed on opposite sides of the second sub-container 22b; the second sub-container 22b has multiple receiving spaces. The placement of the first sub-container 22a on opposite sides of the second sub-container 22b better reflects the actual working scenario of welders. Specifically, the first sub-container 22a is used to store disassembled welding rods. Thus, welders standing on either side of the welding material transport cart 100 are closer to the first sub-container 22a, making it more convenient for them to retrieve the disassembled welding rods.

[0055] The second sub-container 22b stores unopened welding rods. Since the welding rods are packaged in a relatively regular structure, and the packaging consists of multiple cuboid structures before opening, the shape of the multiple storage spaces within the second sub-container 22b can be rectangular, but is not limited to this. The second sub-container 22b has multiple storage spaces, allowing multiple unopened welding rods to be loaded simultaneously. This increases the daily loading capacity of the welding material transport trolley (100 units) and avoids the waste of time caused by repeatedly retrieving welding rods.

[0056] In this way, the first sub-container 22a is placed on opposite sides of the second sub-container 22b, and multiple second sub-containers 22b are provided with a holding space. In this way, the unsplit welding rods that are not frequently used are placed in the middle position, which is farther away from the welding workers, while the split welding rods that are frequently used are placed in the position closer to the welding workers. This makes it more convenient for the welding workers to take and classify them, and can better meet the needs of the actual welding environment.

[0057] In some embodiments, the plurality of storage components 2 include a waste storage container 23 disposed on the bearing surface 10; the waste storage container 23 is provided with a partition plate for separating packaged waste and metal waste. The shape of the waste storage container 23 includes square, circular, and rectangular shapes, and it may be rectangular. Specifically, the structure of the waste storage container 23 can be understood as a rectangular cylinder without a lid and having a receiving cavity.

[0058] The waste storage container 23 can be used to store waste; it is equipped with a divider to separate packaging waste and metal waste. The metal waste may still be hot; if packaging waste and metal waste are placed together, a fire may occur, causing a safety accident.

[0059] In this way, separating packaging waste from metal waste not only optimizes the working environment but also facilitates subsequent recycling and processing, while avoiding secondary pollution or safety hazards caused by metal residues mixing with packaging waste.

[0060] Optionally, an intelligent, compartmentalized waste storage container 23 can be installed, which includes movable partitions, a gravity sorting mechanism, or a mechanical partitioning device to automatically sort and store packaging waste generated from the disassembly and assembly of welding materials, as well as metal waste such as welding rod residues and welding wire ends.

[0061] Specifically, a movable partition is installed inside the waste storage container 23 to divide the space into a packaging waste area and a metal waste area. The partition is connected to the trolley body 1 via a slide rail for easy manual adjustment. An inclined guide trough is installed at the bottom of the metal waste area to allow the welding rod residue and welding wire head to slide into the designated area by gravity, thus avoiding mixing with lightweight packaging waste. A rotating sorting wheel is installed at the waste inlet to automatically classify waste according to a preset sorting logic.

[0062] In this way, through intelligent separation design, the efficiency of waste sorting is significantly improved, reducing manual sorting time; at the same time, it avoids secondary pollution or safety hazards caused by metal residues being mixed with packaging waste.

[0063] In some embodiments, the vehicle body 1 includes a main frame 11 and a walking device 12. At least a portion of the upper surface of the main frame 11 forms a bearing surface 10. The walking device 12 includes a plurality of wheels 12a disposed at the bottom of the main frame 11. The bearing surfaces 10, which at least a portion of the upper surface of the main frame 11, are used to support a plurality of storage items 2. Therefore, the main frame 11 provides support for the storage items 2.

[0064] Multiple wheels 12a are located at the bottom of the main frame 11, and the number of wheels 12a can be selected as four. In this way, the welding material transport trolley 100 can be driven to realize the function of transporting welding materials.

[0065] Therefore, the main body of the welding material includes a main frame 11 and a walking device 12, and the storage component 2 is placed on the bearing surface 10 of the main frame 11. In this way, the main frame 11 and the walking device 12 provide the function of bearing and transporting the welding material transport trolley 100.

[0066] In some embodiments, the traveling wheel 12a is a swivel wheel. A swivel wheel is a movable caster, which, compared to a fixed caster that can only rotate vertically, can rotate 360° horizontally under dynamic or static loads. This makes the movement of the welding material transport trolley 100 more flexible.

[0067] The materials used for the casters include nylon, polyurethane, rubber, and cast iron, while the materials for the caster bearings include iron core, steel core, aluminum core, and plastic core. The casters themselves can be made of nylon, and the caster bearings can be made of steel.

[0068] The traveling device 12 also includes a shock-absorbing component 12b and a braking device 12c. The shock-absorbing component 12b is located between the traveling wheel 12a and the main frame 11. The braking device 12c is connected to both the main frame 11 and the traveling wheel 12a, and is used for braking. The shock-absorbing component 12b provides shock absorption for the traveling wheel 12a, reducing significant vibrations when the trolley passes over the track. The braking device 12c provides braking for the traveling wheel 12a, preventing it from slipping when the trolley is stopped.

[0069] The shock absorption component 12b includes springs, rubber pads, etc., and a spring buffer device can also be added inside the wheel axle to achieve shock absorption and ensure smooth transportation of the welding material transport trolley 100. The braking device 12c can be understood as a mechanical structure used to fix the traveling wheel 12a, and can be friction pads, clips, etc., for braking the traveling wheel 12a.

[0070] Thus, using casters as the traveling wheels 12a allows for 360° rotation, making the movement of the welding material transport trolley 100 more flexible; the shock-absorbing component 12b reduces the bumps of the welding material transport trolley 100 and prevents the welding material from falling off; the braking device 12c prevents the vehicle from rolling away when stopped. Therefore, the shock-absorbing component 12b and the braking device 12c can further improve the stability of transportation.

[0071] Optionally, a dynamic balance adjustment mechanism can be introduced into the swivel wheels at the bottom of the trolley. This mechanism uses sensors and a hydraulic system to adjust the wheel support force in real time to adapt to transportation needs under different ground conditions, such as tracks, ramps, and uneven ground. Specifically, pressure and tilt sensors are installed on each swivel wheel to monitor the ground slope and wheel stress in real time. Based on the sensor data, the vertical height and horizontal support force of the swivel wheels are dynamically adjusted via hydraulic rods to ensure the trolley remains level in complex terrain. A central controller coordinates the adjustment actions of each wheel, prioritizing the reduction of support force on higher wheels to balance the vehicle body and reduce the impact of bumps on the welding materials.

[0072] Thus, the introduction of a dynamic balancing system significantly improves the transport stability of the trolley under complex ground conditions, making it particularly suitable for open-air operations such as wind turbine towers. By adjusting the support force in real time, vibration and overturning issues during the transport of welding materials can be effectively reduced, while also lowering pushing resistance and improving ease of operation.

[0073] In some embodiments, the welding material transport trolley 100 further includes a handle 3, which is connected to the main frame 11. Thus, by pushing or pulling the handle 3, the main frame 11 is moved, thereby realizing the transport function of the welding material transport trolley 100.

[0074] Optionally, a U-shaped adjustable height handle 3 can be provided. The handle 3 is connected to the main frame 11 via a threaded adjustment rod. The threaded adjustment rod can be used to adjust the angle between the handle 3 and the main frame 11 at the connection point, thereby meeting the application requirements of different transport weights and different transport scenarios.

[0075] Optionally, by analyzing the load distribution of handle 3 through finite element analysis, the connection angle between handle 3 and the main frame 11 can be reasonably set to further improve the connection strength between handle 3 and the main frame 11 and extend the service life of handle 3 of welding material transport trolley 100. Optionally, while connecting handle 3 to the main frame 11, it can also be connected to the side wall of the storage component to further improve the connection strength between handle 3 and trolley body 1 and enhance the stability during welding material transport.

[0076] Finally, it should be noted that other embodiments of this application will readily conceive of by those skilled in the art upon consideration of the specification and practice of the application disclosed herein. This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein, and is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and alterations may be made without departing from its scope. The scope of this application is limited only by the appended claims.
