Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, and in particular to a circular tube handling device. Background Technology

[0002] In the shipbuilding industry, welded pipes (such as welded water pipes and oil pipes) are core components for transporting fluids or gases, and their handling operations are carried out throughout the entire process of cutting, welding, and assembly. Since shipbuilding involves a large number of piping systems, welded pipes are usually characterized by long length, heavy weight, and high surface precision requirements, posing significant challenges to traditional handling methods.

[0003] Taking a shipbuilding welding workshop as an example, welded pipes are mostly handled manually with the aid of ordinary forklifts. Operators must manually adjust the position of the welded pipes on the forklift forks, which is not only inefficient, but also causes the welded pipes to roll and shift due to the unstable contact between the circular cross-section and the fork plane. This can lead to minor positioning misalignments requiring repeated adjustments, or even serious slippage accidents, threatening personnel safety. In addition, during manual handling, the surface of the welded pipes is easily subjected to hard friction with the metal forks or scratched by tools, affecting the subsequent welding quality and pipe sealing performance. Especially for oil pipes that need to be handled in the narrow confines of a ship's hold, traditional forklifts cannot flexibly adjust the fork arm spacing to accommodate different pipe diameters, and lack auxiliary positioning mechanisms. Welded pipes are very prone to deviating from their target position when placed, increasing assembly errors.

[0004] While existing technologies attempt to improve stability by adding fixing clamps or straps, the operation is cumbersome and cannot enable fine-tuning of the welded pipe during transportation, resulting in the need for multiple manual corrections of the orientation before welding, which restricts project efficiency. Utility Model Content

To this end, this invention proposes a circular tube handling device that can accurately position circular tubes, reduce adjustment time, protect the surface of the tubes, ensure performance, effectively improve handling efficiency, reduce labor intensity, and is highly adaptable to handling circular tubes of different diameters, making it widely applicable in industries such as shipbuilding.

[0006] The circular tube handling device according to an embodiment of the present invention includes:

[0007] A forklift includes a drive unit and a fork carriage, the drive unit being capable of driving the fork carriage to move in a vertical direction, the fork carriage including two fork arms;

[0008] Two support components are connected to the fork arm in a one-to-one correspondence.

The opposite walls of the V-shaped groove are provided with universal balls to roll with the circular tube.

[0009] Two auxiliary feeding components are connected to the fork frame and arranged correspondingly to the fork arms.

[0035] In the shipbuilding industry, welded pipes (such as welded water pipes and oil pipes) are core components for transporting fluids or gases, and their handling operations are carried out throughout the entire process of cutting, welding, and assembly. Since shipbuilding involves a large number of piping systems, welded pipes are usually characterized by long length, heavy weight, and high surface precision requirements, posing significant challenges to traditional handling methods.

[0036] Taking a shipbuilding welding workshop as an example, welded pipes are mostly handled manually with the aid of ordinary forklifts. Operators must manually adjust the position of the welded pipes on the forklift forks, which is not only inefficient, but also causes the welded pipes to roll and shift due to the unstable contact between the circular cross-section and the fork plane. This can lead to minor positioning misalignments requiring repeated adjustments, or even serious slippage accidents, threatening personnel safety. In addition, during manual handling, the surface of the welded pipes is easily subjected to hard friction with the metal forks or scratched by tools, affecting the subsequent welding quality and pipe sealing performance. Especially for oil pipes that need to be handled in the narrow confines of a ship's hold, traditional forklifts cannot flexibly adjust the fork arm spacing to accommodate different pipe diameters, and lack auxiliary positioning mechanisms. Welded pipes are very prone to deviating from their target position when placed, increasing assembly errors.

[0037] While existing technologies attempt to improve stability by adding fixing clamps or straps, the operation is cumbersome and cannot enable fine-tuning of the welded pipe during transportation, resulting in the need for multiple manual corrections of the orientation before welding, which restricts project efficiency.

[0038] Therefore, such as Figures 1 to 3As shown, the circular tube handling device proposed in this utility model includes a forklift 100, two supporting components 200, and two auxiliary feeding components 300. The forklift 100 includes a drive unit 110 and a fork 120. The drive unit 110 can drive the fork 120 to move in the vertical direction. The fork 120 includes two fork arms 121. Correspondingly, the supporting components 200 are connected to the fork arms 121 one by one. Further, the supporting components 200 include two supporting blocks 210. The two supporting blocks 210 are arranged opposite each other and form a V-shaped groove for positioning the circular tube 400. The opposite walls of the V-shaped groove are provided with universal balls 220 for rolling cooperation with the circular tube 400. In addition, two auxiliary feeding components 300 are respectively connected to the fork 120 and arranged in a corresponding manner to the fork arm 121. The auxiliary feeding component 300 includes a first power wheel 310 and a second power wheel 320. The first power wheel 310 can abut against the bottom of the round tube 400 and drive the round tube 400 to move axially, and the second power wheel 320 can abut against the bottom of the round tube 400 and drive the round tube 400 to rotate circumferentially. It should be noted that the forklift 100 drive unit 110 and the specially designed support component 200 and auxiliary feeding component 300 enable the rapid and efficient handling of the round tube 400. The design of the V-groove and the universal ball 220 ensures the stable positioning of the round tube 400 during handling, avoiding the risk of slipping off the fork arm 121. Furthermore, the first drive wheel 310 and the second drive wheel 320 drive the round tube 400 to move axially and circumferentially, respectively, enabling flexible handling and adjustment of the round tube 400. This ensures that the round tube 400 is stably positioned in the V-groove and assists workers in handling and adjusting its position, such as linear displacement adjustment and rotational adjustment, to align the round tube 400 to a suitable position for welding. This ensures the efficiency and reliability of the handling process. The overall structure is reasonably designed, easy to operate, and has low maintenance costs, making it suitable for large-scale promotion and application.

[0039] In some embodiments of this utility model, the support block 210 is equipped with a ball-head plunger, and the end of the ball-head plunger is provided with a universal ball 220. The ball-head plunger provides flexible support and positioning, while the universal ball 220 achieves multi-directional rolling engagement with the welded pipe through its contact surface, preventing the welded pipe from rolling and shifting due to unstable contact between its circular cross-section and the fork plane. Therefore, operators do not need to manually adjust the position of the welded pipe, improving handling efficiency and safety. Simultaneously, the use of the universal ball 220 reduces the risk of surface damage to the circular pipe 400, ensuring the pipe's sealing performance. It is easy to understand that the ball-head plunger and the support block 210 are connected by threads, and the ball-head plunger contains a spring. The universal ball 220, through the spring, has a certain degree of flexibility, enabling it to adapt to the circular pipe 400 with surface deformation defects. Referring again... Figures 1 to 3In some embodiments of this utility model, there are multiple ball plungers, that is, multiple universal balls 220. The multiple universal balls 220 are arranged to fill the groove surface of the V-shaped groove, so that the round tube 400 can roll and be positioned more smoothly in the V-shaped groove, thus protecting the surface accuracy of the round tube 400.

[0040] Specifically, multiple omnidirectional balls 220 can be evenly arranged on the surface of the V-shaped groove, thereby ensuring that the circular tube 400 can contact the omnidirectional balls 220 at multiple locations. As a preferred embodiment, the omnidirectional balls 220 can be made of wear-resistant materials to further improve their service life and performance.

[0041] Refer to Figure 3 In some embodiments of this utility model, the fork arm 121 is provided with an adjustment groove 12101, and the support block 210 is adjustablely installed on the fork arm 121 along the length direction of the adjustment groove 12101. The design of the adjustment groove 12101 allows the position of the support block 210 to be adjusted as needed to accommodate round tubes 400 of different diameters, improving the flexibility and adaptability of the device, enabling it to handle round tubes 400 of various specifications. More importantly, by controlling the relative distance between the two support blocks 210, it is possible to effectively control the round tubes 400 of different specifications to sink to a lower position, so that the bottom of the round tube 400 can contact the first power wheel 310 and the second power wheel 320, so that the first power wheel 310 and the second power wheel 320 can drive the round tube 400 to move. Optionally, in some embodiments of this utility model, the bottom of the support block 210 is provided with a threaded hole (not shown in the figure), and the support block 210 and the fork arm 121 are fixed by screws located in the threaded hole and the adjustment groove 12101, which is simple in structure and easy to install.

[0042] Refer to Figure 1 and Figure 2 In some embodiments of this utility model, the centerline of the first drive wheel 310 is arranged perpendicular to the centerline of the circular tube 400. This allows the first drive wheel 310 to effectively drive the circular tube 400 axially while preventing rolling displacement of the circular tube 400 during transport. By arranging the centerline of the first drive wheel 310 perpendicular to the centerline of the circular tube 400, it ensures that the force applied by the first drive wheel 310 when contacting the bottom of the circular tube 400 effectively pushes the circular tube 400 along its axial direction without causing it to roll. Furthermore, the centerline of the second drive wheel 320 is arranged parallel to the centerline of the circular tube 400. This allows the second drive wheel 320 to drive the circular tube 400 to rotate circumferentially, enabling stable circumferential rotation of the circular tube 400 during transport and avoiding the rolling displacement problem caused by unstable contact between the circular tube 400 cross-section and the fork plane in traditional transport methods. (Refer to...) Figure 3In some embodiments of this utility model, the fork 120 is connected to two conduits 122, which are arranged one-to-one with the auxiliary feeding components 300. The conduits 122 can carry electrical wires to energize the first drive wheel 310 and the second drive wheel 320. For example, both the first drive wheel 310 and the second drive wheel 320 have an internal coil and an external iron wheel structure; energizing the coil drives the iron wheel to rotate. It should be noted that the conduits 122 allow the electrical wires to be smoothly connected to the drive wheels, ensuring stable operation. The conduits 122 can be made of flame-retardant materials to meet the requirements of welding environments. Furthermore, the drive device 110 is electrically driven and can share the same power supply as the electrical wires in the conduits 122, simplifying the power control system. It should be noted that the drive device 110 drives the vertical movement of the fork 120, which can be referenced from the existing electric forklift 100 structure, and will not be described in detail here.

[0043] Refer to Figure 3 In some embodiments of this utility model, the auxiliary feeding component 300 is placed between the two supporting components 200, which has a compact structure. Furthermore, the auxiliary feeding component 300 is placed inside, which can avoid the risk of the first power wheel 310 and the second power wheel 320 being accidentally touched during operation, thereby improving the safety of workers' operation.

[0044] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
