Description

Technical Field

[0001] This utility model specifically relates to a marine sidewall pyrotechnic trolley. Background Technology

[0002] During shipbuilding and repair, heat input processes such as welding introduce large amounts of heat into localized areas of metal materials. The shrinkage stress generated during metal cooling often leads to deformation or warping of materials or components. Excessive deformation can severely hinder the installation and fit between components, even reducing the overall strength and stiffness of the structure, and significantly diminishing its aesthetics. To overcome the problems caused by deformation, it is necessary to straighten the deformed materials or components. Fire straightening is a common deformation straightening method and a crucial process in shipbuilding and repair, characterized by its complexity and high manpower and resource consumption. Currently, most shipbuilding and repair companies rely on manual labor for construction, which typically involves high-temperature operations, posing significant safety hazards, low efficiency, and poor quality consistency. Furthermore, fire straightening of high-positioned panels requires ladders and other tools, which is time-consuming, labor-intensive, and carries the risk of falls. Inexperienced operators can easily cause insufficient heating or localized overheating. The operator's skill level directly affects the repair outcome; substandard techniques can lead to panel repair failure or even new deformation or cracks. Furthermore, most automated equipment used for pyrotechnic straightening operations is currently applied in relatively horizontal operating environments, such as ship decks.

[0037] Furthermore, the flame work module 2 and the main body plate 1 are quickly connected and installed by screws and the slider 20 and guide rail slider 24 on the lead screw 21-1 to form the main body of the flame straightening operation. The flame work plate 8 is installed on the mounting plate 7. The two are connected by spring 15 and spring support rod 14. The fixed wheel frame 13 is welded to the flame work plate 8. Finally, as needed, the pipe joint 9, welding nozzle joint 10, and welding gun nozzle 11 are connected in sequence by threads. When connecting, the distance with the positioning wheel 12 can be adjusted so that the flame gun and the contact surface are always kept at the same distance during operation, thereby ensuring the quality of heating and straightening. At the same time, the wheel frames on both sides can prevent the problem of sparks splashing during heating, and play a certain role in isolation, ensuring the safety of the flame straightening process.

[0038] Furthermore, the main body plate 1 is provided with a drive assembly and a linear guide rail 23. The linear guide rail 23 is provided with a slider. The mounting plate 7 of the flame operation module 2 is set on the slider. The drive assembly is connected to the mounting plate 7 of the flame operation module 2, driving the mounting plate 7 of the flame operation module 2 to move back and forth along the linear guide rail 23 via the slider.

[0040] The first driving source is the first servo motor 16-1.

[0041] Furthermore, two linear guide rails 23 are fixed on the main body plate 1, and guide rail sliders 24 are fitted onto them. During operation, the sliders are connected to the mounting plate 7 by bolts for fixation. Support ends 18 and fixed ends 22 are fixed at both ends of the plate, respectively. The fixed ends mainly serve to support and position, stabilizing the screw position and ensuring motion accuracy. The support ends bear the responsibility of bearing axial force and ensuring stable operation of the screw, while reducing friction and improving the screw's motion accuracy. A first screw nut 19 and a screw slider 20 are fitted onto the first ball screw 21-1. The slider has threaded holes for connection with the mounting plate 7 for movement. After the first ball screw 21-1 is fixed to the two supports by bolts on both sides, an elastic coupling 17 is installed at the support end 18. The servo reducer 17 is mounted on the reducer base 25 through a threaded hole and connected to the flexible coupling through a connecting key.

The double-brake casters can simultaneously brake the wheels and steer, achieving maximum stability, suitable for applications requiring high stability and safety, such as ships. Several bottom supports 36 are installed on the trolley base 38 to secure the lifting device, gas cylinders, and other structures, preventing instability.

[0044] Example 2

[0045] like Figure 4 As shown, based on Embodiment 1, the overall lifting and rotating module of the tooling is further limited, and the performance of Embodiment 2 after the limitation is even better.

[0046] Furthermore, the tooling overall lifting and rotating module 3 includes a connecting rod 34, a motor control device 28, a lifting platform 32, and a lifting mechanism. The lifting mechanism is mounted on the trolley traveling mechanism module 5, the lifting platform 32 is mounted on the lifting platform 32, the motor control device 28 is mounted on the lifting platform 32, and the connecting rod 34 is mounted on the lifting platform 32 via a bearing. One end of the connecting rod 34 is connected to the output end of the motor control device 28, and the outer end of the connecting rod 34 is used to connect to the main body plate 1.

[0047] Furthermore, the tooling overall lifting and rotating module 3 includes a connecting rod 34 connecting to the main body plate 1, a motor control device 28, a platform 32 supporting its lifting, a second lead screw 21-2 for lifting, and a second servo motor 16-2 providing power for the lead screw's lifting. Four guide rails 27 and the second lead screw 21-2 are installed on the bottom support of the trolley, and a second lead screw nut 29 is fitted onto them to support the lifting platform 32. Two transmission pulleys 30 and a transmission belt 31 are installed on one side of the bottom of the lead screw to form a mechanical transmission device. A servo reducer and the second servo motor 16-2 are fixed to the bottom support above the pulleys by threads, thereby transmitting the output torque to the lead screw device to achieve lifting. Two bearing seats 35 are fixed to the lifting platform 32 by threads, through which the connecting rod 34 passes, one end connecting to the main body plate 1 and the other end connecting to the motor control device 28. During operation, the motor control device 28 can output torque to rotate the connecting rod 34, causing the main plate to rotate to a horizontal position. This enables horizontal flame straightening operations, allowing for multi-angle and all-around flame work, expanding the work coverage, and enabling continuous straightening operations. This avoids problems such as incomplete straightening and improves the efficiency of flame work.

[0048] Furthermore, the lifting mechanism includes a vertically arranged guide rail frame, a second lead screw 21-2, and a second drive source. A second lead screw nut 29 is sleeved on the second lead screw 21-2. The lifting platform 32 is set on the guide rail frame. The second drive source is connected to one end of the second lead screw 21-2, driving the second lead screw 21-2 to rotate. The second lead screw nut 29 drives the lifting platform 32 to move up and down along the guide rail frame.

[0049] Furthermore, the second drive source is the second servo motor 16-2.

[0050] The guide rail frame includes multiple vertically arranged guide rails 27, and the lifting platform 32 is set on each guide rail 27 and can move up and down along the guide rail 27.

[0051] There are four guide rails 27, and the four corners of the lifting platform 32 are respectively set on the four guide rails 27.

[0052] Furthermore, a temperature control probe and sensor are provided on one side of the fire-working module 2;

[0053] Furthermore, during the heating process, a temperature control probe and sensor can be installed near the flame work module 2 to achieve real-time monitoring of parameters such as temperature distribution and deformation degree during the flame straightening process, thereby achieving precise control.

[0054] The ignition operation module 2 includes two welding torch nozzles. In specific implementation, different numbers of nozzles can be set according to work requirements, and water pipes can also be added to meet the needs of rapid cooling.

[0055] The working process of this utility model is as follows: First, the trolley walking mechanism module 5 is moved to the front of the bulkhead where the work needs to be done. Then, the lifting module 3 is quickly installed and combined onto the bottom support of the trolley. Next, the main body plate 1 is fixed to the connecting shaft 34 through the central hole. Then, the flamethrowing module 2 is installed on the main body plate 1 through the threaded hole. Finally, the flamethrowing gun and the gas container 6 are connected through the gas supply hose to complete the assembly of the whole component. After the quick assembly is completed, the tooling is placed close to the side wall to be corrected, so that the two positioning wheels 12 are pressed against the wall surface. The position of the flamethrowing gun relative to the center of the positioning wheels is adjusted and fixed, so that the flamethrowing gun always maintains the same distance from the wall surface. After adjusting the flamethrowing gun nozzle to the area to be corrected by lifting the screw on the main body plate 1, the flamethrowing gun is turned on to release heat energy to eliminate the residual stress of the wall panel and achieve the purpose of correcting the deformation. The size of the flame can be controlled by adjusting the regulating valve on the gas container 6. In addition, the design of the flexible gas supply pipeline can adapt to the needs of movement and operation at different angles. When the area of ​​the deformable wall panel is large, the screw lifting mechanism and the rotation of the connecting rod and bearing can be flexibly used to achieve heating of the entire panel from multiple directions.

[0056] In summary, based on modular design, the modules can be quickly assembled and disassembled, effectively solving the problem of the large overall weight of the pyrotechnic trolley making it difficult to transport. Furthermore, the combination of multi-nozzle spray guns, ball screw lifting devices, and rotating mechanisms allows for more comprehensive pyrotechnic coverage and improved efficiency. The modular design of this marine sidewall pyrotechnic trolley provides a reliable structure and good performance. Through modular design, it achieves rapid assembly and disassembly of the modules. The combination of lifting and rotating mechanisms allows the flame nozzles to be precisely positioned in the deformed area for localized heating and correction. This precise operation avoids overheating or uneven heating, thus improving the quality and stability of the correction effect. Compared to traditional manual correction operations, this pyrotechnic trolley can move and position continuously, enabling large-scale continuous operation. Through gas supply pipes and control devices, the heating temperature of the flame nozzles is ensured to be stable and controllable, eliminating residual stress in the wall panels and preventing damage to the wall panel material due to excessive temperature. The trolley has a compact structure and flexible movement, allowing operation in the confined space inside the ship's cabin. The equipment is designed with intelligence and automation, allowing workers to achieve precise correction through simple operation. This reduces the skill and experience requirements for operators, lowers labor costs, and minimizes the time workers spend directly in contact with the flame, effectively reducing labor intensity and safety risks. Fixed wheels ensure that the nozzle maintains the same distance from the contact surface during flame work, thus better adapting to different wall panel deformation areas, improving the tooling's environmental adaptability, and achieving high-quality flame correction.

[0057] Due to the complexity of the work, the working space at the ship's bulkhead location is often limited when manually straightening bulkheads, restricting the operator's movement and tool usage. The sidewall heat treatment trolley can be precisely positioned within a limited space and automatically control the heating area, avoiding errors caused by the confined space during manual operation. Manual straightening is difficult to guarantee uniform heating, which may lead to overheating or uneven cooling in some areas, generating new thermal stress or cracks. The sidewall heat treatment trolley, through its automated control system, ensures the accuracy of the heating process, avoiding localized overheating or uneven heating. Simultaneously, during the heating process, operators are often in a high-temperature working environment, posing safety hazards such as fire, burns, and gas leaks. The sidewall heat treatment trolley's automated operation allows operators to remotely control the trolley, maintain a safe distance from the high-temperature area, and reduce the time operators spend directly in contact with the heating equipment in a high-temperature environment, thereby reducing the safety risks during operation. Setting operating parameters via remote control avoids errors and frequent manual adjustments inherent in manual operation, resulting in more stable operation, enabling continuous work for extended periods without frequent breaks, reducing human interference, and improving the continuity and stability of the operation.
