Description

Technical Field

[0001] This application relates to the field of pneumatic rail welding machine technology, and in particular to a multi-scenario containerized rail welding vehicle. Background Technology

[0002] Rail welding is a crucial step in seamless track technology. With the rapid development of railway construction in my country, large-scale rail welding vehicles or containerized flash welding are commonly used for on-site rail welding during seamless track replacement and overhaul. CNC rail welding machines, as the core component of these large-scale or containerized welding vehicles, are experiencing rapid expansion in application, leading to a surge in welding workload. Flash welding utilizes resistance heating combined with an electric arc flash (resistance heating at the contact surface creates continuous flashes), culminating in upsetting pressure to achieve connection. Gas pressure rail welding machines use an oxy-acetylene flame to heat the rail to a plastic state, then apply upsetting pressure to achieve atomic diffusion bonding. Therefore, containerized power supplies used in flash welding are not suitable for gas pressure welding. Summary of the Invention

[0003] To realize the welding process of pneumatic rail welding, this application provides a multi-scenario containerized rail welding vehicle.

[0004] This application provides a multi-scenario containerized rail welding vehicle with the following technical solution:

[0005] A multi-scenario containerized rail welding vehicle includes a flatbed truck.

[0012] The main control room is also equipped with an air-cooled cooler and an explosion-proof fan. The air-cooled cooler is fixedly installed on the side wall of the main control room and located above the hydraulic module and the water-cooled module. The air-cooled cooler is used to cool the hydraulic oil and cooling water.

[0013] The explosion-proof fan is located on the side wall of the main control room, directly opposite the air-cooled cooler. The explosion-proof fan is used to draw hot air from the main control room and exhaust it from the main control room.

[0014] Optionally, a partition is provided between the main control room and the oxygen storage room. The partition has a manhole and a sliding door is provided through the manhole. The oxygen storage room is equipped with oxygen cylinders, oxygen cylinder mounting brackets, storage cabinets, indoor air conditioning units, and outdoor air conditioning units. The oxygen cylinder mounting brackets are fixedly installed on the inner wall near the side of the flatbed truck. The oxygen cylinders are installed on the oxygen cylinder mounting brackets. The distance between the oxygen cylinders is greater than 20 centimeters. The storage cabinet is located on the side wall of the oxygen storage room directly opposite the oxygen cylinders. The indoor air conditioning unit is located on the side wall of the oxygen storage room directly opposite the partition. The outdoor air conditioning unit is located on the same side as the storage cabinet and is located above the storage cabinet.

The lifting mechanism includes a support arm whose bottom is fixed to the rotating mechanism and whose top is rotatably connected to the rear end of the telescopic mechanism, and a lifting assembly whose bottom is supported by the rotating mechanism and is rotatably connected. The top of the lifting assembly is rotatably connected to the telescopic mechanism. The rotatable connection between the top of the lifting assembly and the telescopic mechanism is located in the middle of the telescopic mechanism.

[0017] The support arm is inclined towards the rear end of the flatbed vehicle from bottom to top, and the telescopic mechanism is located at the front end of the support arm for extending and retracting the pneumatic rail welding machine onto the rail; the bottom of the support arm and the bottom of the lifting assembly are spaced apart in the straight line between the front and rear ends of the flatbed vehicle.

[0018] Optionally, the flatbed truck is equipped with a container, and the partition, main control room and oxygen storage room are all located inside the container. The container is equipped with a floor, and the floor is spaced apart from the bottom of the container to leave room for wiring.

[0019] The hydraulic module also includes hydraulic pipelines, the power module also includes electrical wiring, the air-cooled module also includes air-cooled pipelines, and the water-cooled module also includes water-cooled pipelines.

[0020] The hydraulic pipeline passes through the base plate from the output end of the hydraulic pump and enters the wiring space. The electrical wires are connected from the electrical control cabinet, pass through the base plate and enter the wiring space. The air-cooled pipeline is connected from the air tank, passes through the base plate and enters the wiring space. The water-cooled pipeline is connected to the output end of the water pump, passes through the base plate and enters the wiring space.

[0021] The hydraulic pipelines, electrical lines, air-cooled pipelines, and water-cooled pipelines are all located in the middle of the wiring space and then exit from the container. After exiting the container, the hydraulic pipelines, electrical lines, air-cooled pipelines, and water-cooled pipelines converge and connect to the pneumatic rail welding machine.

[0022] Optionally, it also includes acetylene and oxygen pipelines. The acetylene pipeline connects to the acetylene tank in the acetylene storage chamber and extends from the side wall of the acetylene storage chamber. The oxygen tank and acetylene tank are located on the transverse sides of the flatbed truck, respectively. The acetylene pipeline runs from the side wall of the container into the wiring space below the oxygen storage chamber. The oxygen pipeline exits from the oxygen tank and enters the wiring space from the bottom plate. The distance between the acetylene and oxygen pipelines is greater than 3 meters. After exiting the wiring space, the acetylene and oxygen pipelines converge with hydraulic pipelines, electrical lines, air-cooled pipelines, and water-cooled pipelines to connect to the pneumatic rail welding machine.

[0023] Optionally, the flatbed is equipped with a mounting base located in front of the container. The take-up and take-down device and the pneumatic rail welding machine are both located on the mounting base.

The airflow manifold in the acetylene storage chamber is used to connect all acetylene tanks, and the airflow manifold in the oxygen storage chamber is used to connect all oxygen tanks.

[0025] Optionally, multiple explosion-proof fans are provided, which are arranged horizontally and located on the same horizontal plane, and all of the explosion-proof fans are located above the generator.

[0026] Optionally, the partition plate has ventilation holes at the bottom. Multiple ventilation holes are provided and are opened laterally along the partition plate. The cold air in the oxygen storage chamber sinks through the ventilation holes and enters the main control chamber, and gradually rises along the bottom of the main control chamber to cool the welding control components.

[0027] Optionally, the air-cooled cooler is connected to both the hydraulic pipeline and the water-cooling pipeline to cool the hydraulic oil and cooling water returning to the hydraulic oil tank and water tank.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] Based on the safe storage ranges for oxygen and acetylene, the distance between them must be greater than 10 meters. However, due to the overall length limitation of the flatbed truck, the overall length of the flatbed truck must be controlled within 12 meters. Furthermore, based on the safe storage range for acetylene, the distance between the acetylene tank and the heat source must be greater than 3 meters, and due to the flatbed truck length limitation, this distance must be controlled within 5 meters. Therefore, the length of the main control room is limited to 5-9 meters. Because of the use of the pneumatic rail welding machine, a large number of devices are installed in the main control room, requiring creative planning of equipment placement. Additionally, the generator is large and its length exceeds the width of the main control room, and there are power supply outlets on both sides of the main control room. The access door for operators restricts the generator to be installed only along the length of the main control room. To regulate power delivery, the electrical control cabinet is installed on one side of the generator. Furthermore, the generator generates significant heat during operation, which could affect other equipment. Therefore, a maintenance access passage is provided in the middle of the main control room to minimize impact on other equipment and to allow access for maintenance personnel. Due to heat effects, the hydraulic, air-cooled, and water-cooled modules are installed on the other side of the main control room, ensuring a minimum distance of 50 centimeters between them and the generator, thereby reducing the temperature impact on these modules.

[0030] The hydraulic modules are arranged vertically, which reduces the space they occupy and facilitates the delivery of oil from the tank to the actuator via the hydraulic pump. Because the water-cooled module is less affected by temperature, it is placed adjacent to the hydraulic modules and also arranged vertically to minimize its space requirements. The air-cooled module compresses the gas in the main control chamber. Since the air temperature near the air compressor is high, its compression efficiency is relatively low. Therefore, the air-cooled module is placed between the water-cooled module and the oxygen storage chamber. Furthermore, because the oxygen storage chamber has better temperature control and a lower air temperature near it, the compressed air temperature remains low, ensuring the air compressor's compression efficiency and effectiveness. Finally, after compressing the air, the compressed air is stored in an air tank for air-cooling operations. Attached Figure Description

[0045] The following is in conjunction with the appendix Figure 1 - Appendix Figure 7 This application will be described in further detail.

[0046] This application discloses a multi-scenario containerized rail welding vehicle. (Refer to...) Figure 1 and Figure 2 The multi-scenario containerized rail welding vehicle includes a flatbed truck 1. From the rear end to the front end of the flatbed truck 1, there are sequentially arranged an acetylene storage chamber 2, a passageway 3, a main control room 4, an oxygen storage chamber 5, and a welding machine operation area 6. The distance between the oxygen storage chamber 5 and the acetylene storage chamber 2 is 10-12 meters. In this embodiment, the distance between the oxygen storage chamber 5 and the acetylene storage chamber 2 is 11 meters. The passageway 3 is 3-5 meters long and is used to connect the main control room 4 and the acetylene storage chamber 2. In this embodiment, the length of the passageway 3 is 4 meters. The length of the main control room 4 is 5-9 meters. In this embodiment, the length of the main control room 4 is 5.5 meters.

[0047] Reference Figures 2-5 The main control room 4 is equipped with a welding machine control component 7, which includes a hydraulic module 71, a power module 72, an air-cooled module 73, and a water-cooled module 74.

[0048] Reference Figures 2-5 Hydraulic module 71, water-cooled module 74 and air-cooled module 73 are located on the same side of the main control room 4, and power module 72 is located on the other side of the main control room 4. There is a maintenance passage between power module 72 and hydraulic module 71, air-cooled module 73 and water-cooled module 74, and the width of the maintenance passage is greater than 50 cm.

[0049] Reference Figures 2-5The power module 72 includes a generator 721, a diesel fuel tank 722, and an electrical control cabinet 723. The generator 721 is 4.3 meters long and 1.3 meters wide. The electrical control cabinet 723 is 1.1 meters long. The diesel fuel tank 722 is fixedly installed on the bottom wall of the main control room 4. The generator 721 is fixedly installed above the diesel fuel tank 722. The electrical control cabinet 723 is located on the side of the generator 721 near the oxygen storage room 5.

[0050] Reference Figures 2-5 The hydraulic module 71 includes a hydraulic oil tank 711, a hydraulic pump 712 and a mounting bracket. The mounting bracket is fixedly installed at the bottom of the main control room 4 and near the side wall of the main control room 4 and near the end of the flatbed 1. The hydraulic oil tank 711 and the hydraulic pump 712 are both located inside the mounting bracket. The hydraulic oil tank 711 is located above the hydraulic pump 712 and the hydraulic pump 712 is connected to the hydraulic oil tank 711.

[0051] Reference Figures 2-5 The water-cooled module 74 includes a water tank bracket, a water tank 741, and a water pump. The water tank bracket is located on the side of the mounting frame near the oxygen storage chamber 5. The water tank 741 is fixedly installed on the top of the water tank bracket, and a water outlet pipe is provided at the bottom of the water tank 741. The water pump is located inside the bracket and below the water outlet pipe.

[0052] Reference Figures 2-5 The air-cooled module 73 includes an air compressor 731 and an air tank 732. The air compressor 731 is located on the side of the water tank bracket near the oxygen storage chamber 5, and the air tank 732 is fixedly installed on the side wall of the main control room 4 and located above the air compressor 731.

[0053] Reference Figures 2-5 The main control room 4 is also equipped with an air-cooled cooler 8 and an explosion-proof fan 9. The air-cooled cooler 8 is fixedly installed on the side wall of the main control room 4 and located above the hydraulic module 71 and the water-cooled module 74. The air-cooled cooler 8 is used to cool the hydraulic oil and cooling water.

[0054] Reference Figures 2-5 The explosion-proof fan 9 is located on the side wall of the main control room 4, directly opposite the air-cooled cooler 8. The explosion-proof fan 9 is used to draw hot air from the main control room 4 and discharge it from the main control room 4.

[0055] Based on the safe storage range of oxygen and acetylene, the distance between them must be greater than 10 meters. However, due to the limitation of the overall length of the flatbed truck 1, the overall length of the flatbed truck 1 must be controlled within 12 meters. Furthermore, based on the safe storage range of acetylene, the distance between the acetylene tank and the heat source must be greater than 3 meters, and due to the length limitation of the flatbed truck 1, the distance must be controlled within 5 meters. Therefore, the length of the main control room 4 is limited to 5-9 meters. Because it is used in conjunction with the pneumatic rail welding machine 17, a large amount of equipment needs to be installed in the main control room 4, requiring creative planning of equipment placement. Since the generator 721 is large and its length exceeds the width of the main control room 4, and there are entrances on both sides of the main control room 4 for operators to enter, further consideration is needed. The door allows the generator 721 to be installed only along the length of the main control room 4. To regulate power transmission, the electrical control cabinet 723 is installed on one side of the generator 721. Meanwhile, the generator 721 generates a significant amount of heat during power generation, which can easily affect other equipment. Therefore, a maintenance passage is provided in the middle of the main control room 4 to minimize the impact on other equipment, and this passage is for maintenance personnel to access. Due to the heat effect, the hydraulic module 71, air-cooled module 73, and water-cooled module 74 are installed on the other side of the main control room 4 to ensure a distance of at least 50 centimeters between them and the generator 721, thereby reducing the temperature impact on the hydraulic module 71, water-cooled module 74, and air-cooled module 73.

[0056] Furthermore, the hydraulic module 71 is arranged vertically, which reduces the space occupied by the hydraulic module 71 and facilitates the delivery of oil from the tank to the actuator via the hydraulic pump 712. Since the water-cooled module 74 is less affected by temperature, it is placed adjacent to the hydraulic module 71 and is also arranged vertically to reduce its space requirement. The air-cooled module 73 compresses the gas in the main control chamber 4. When the air temperature near the air compressor 731 is high, the compression efficiency of the air compressor 731 is relatively low. Therefore, the air-cooled module 73 is placed between the water-cooled module 74 and the oxygen storage chamber 5. Additionally, because the oxygen storage chamber 5 has good temperature control, the air temperature near it is low, resulting in lower air temperature drawn by the air compressor 731, thus ensuring the compression effect and efficiency of the air compressor 731. Furthermore, after compressing the air, the air compressor 731 stores the compressed air in the air tank 732 for air-cooling operations.

[0057] Reference Figures 2-5In this embodiment, a partition 10 is provided between the main control room 4 and the oxygen storage room 5. The partition 10 has a manhole and a sliding door is provided through the manhole. The opening direction of the sliding door is parallel to the width direction of the flatbed 1. The oxygen storage room 5 is provided with an oxygen tank 11, an oxygen tank mounting bracket 12, a storage cabinet 13, an indoor air conditioner unit 14, and an outdoor air conditioner unit 15. The oxygen tank mounting bracket 12 is fixedly installed on the inner wall near the side of the flatbed 1. The oxygen tank 11 is installed on the oxygen tank mounting bracket 12. The distance between adjacent oxygen tanks 11 is greater than 20 cm. The storage cabinet 13 is located on the side wall of the oxygen storage room 5 directly opposite the oxygen tank 11. The indoor air conditioner unit 14 is installed on the side wall of the oxygen storage room 5 directly opposite the partition 10. The outdoor air conditioner unit 15 is located on the same side as the storage cabinet 13 and is located above the storage cabinet 13. The air outlet of the outdoor air conditioner unit 15 is located outside the oxygen storage room 5.

[0058] Reference Figures 2-5 Because of the temperature requirements for oxygen cylinder 11 storage, the temperature of oxygen storage chamber 5 needs to be controlled within a low range. Therefore, an indoor air conditioning unit 14 and an outdoor air conditioning unit 15 are installed in oxygen storage chamber 5 to cool and lower the temperature of oxygen storage chamber 5, thereby improving the safety of oxygen storage. At the same time, due to the storage requirements of acetylene cylinder and oxygen cylinder 11, oxygen cylinder 11 can only be placed on the side wall of oxygen storage chamber 5. To improve the space utilization rate in oxygen storage chamber 5, storage cabinets 13 are set in the blank areas of oxygen storage chamber 5 to store other equipment. Because the mass of cold air is large, in order to facilitate the filling of oxygen storage chamber 5 with cold air, the indoor air conditioning unit 14 is placed on the side wall of oxygen storage chamber 5 facing the partition plate 10 and close to the top, so that the cold air covers all oxygen cylinders 11. In addition, to ensure the temperature requirements of oxygen storage chamber 5, a partition plate 10 is built between the main control room 4 and oxygen storage chamber 5 to relatively isolate the heat transfer of the main control room 4.

[0059] Reference Figures 2-5 In this embodiment of the application, the length of the welding machine operation area 6 is 5-6 meters, and further, the length of the welding machine operation area 6 is 5.3 meters. The welding machine operation area 6 is provided with a take-up and put-down device 16 and a pneumatic rail welding machine 17, with the pneumatic rail welding machine 17 located in front of the take-up and put-down device 16.

[0060] Reference Figures 2-5 The retraction device 16 includes a telescopic mechanism, a lifting mechanism, and a rotating mechanism. The lifting mechanism includes a support arm 18 whose bottom is fixed to the rotating mechanism and whose top is rotatably connected to the rear end of the telescopic mechanism, and a lifting component whose bottom is supported by the rotating mechanism and is rotatably connected. The top of the lifting component is rotatably connected to the telescopic mechanism. The rotatable connection between the top of the lifting component and the telescopic mechanism is located in the middle of the telescopic mechanism.

[0061] Reference Figures 2-5The support arm 18 is inclined towards the rear end of the flatbed 1 from bottom to top. The telescopic mechanism is located at the front end of the support arm 18 and is used to retract the gas pressure rail welding machine 17 onto the rail. The bottom of the support arm 18 and the bottom of the lifting assembly are spaced apart in the straight line direction between the front and rear ends of the flatbed 1.

[0062] Reference Figure 2 The telescopic mechanism includes multiple interconnected sleeves 19 and hooks 20. The rear end of the outermost sleeve 19 is hinged to the support arm 18, and the outermost sleeve 19 is hinged to the top of the lifting assembly. The hooks 20 are located at the end of the innermost sleeve 19. The telescopic mechanism also includes multiple telescopic cylinders for driving the sleeves 19 to extend sequentially. The lifting assembly includes lifting cylinders, one end of which is hinged to the rotating mechanism, and the other end is hinged to the bottom of the outermost sleeve 19. The rotating mechanism includes a rotating seat and a hydraulic motor mounted on a flatbed. The bottom of the lifting cylinder is hinged to the rotating seat, and the hydraulic motor is used to drive the rotating seat to rotate and adjust the position of the telescopic mechanism.

[0063] Due to the overall length requirements of the flatbed trolley 1, the overall installation length of the retraction device 16 is limited. Therefore, the end of the telescopic mechanism is installed on the front side of the support arm 18 to reduce the rear space occupied by the telescopic mechanism, thereby maximizing the proximity of the oxygen storage chamber 5 and the support arm 18 and improving the space utilization of the flatbed trolley 1. At the same time, the retraction device 16 adopts four-point force bearing, which improves the stability of the retraction device 16. When the pneumatic rail welding machine 17 is retracted, it is hooked onto the hook 20, and then the telescopic cylinder pushes the sleeve 19 to extend in sequence, thereby driving the pneumatic rail welding machine 17 onto the rail.

[0064] Reference Figure 6 and Figure 2 In this embodiment of the application, a container 22 is provided on the flatbed truck 1. The partition plate 10, the main control room 4 and the oxygen storage room 5 are all located inside the container 22. A bottom plate is provided inside the container 22. The bottom plate is spaced apart from the bottom of the container 22 to leave a wiring space. Furthermore, multiple support rods are provided in the wiring space. The support rods are used to support the bottom plate.

[0065] Reference Figure 6 and Figure 2 The hydraulic module 71 also includes hydraulic pipeline 23, the power module 72 also includes electrical wiring 24, the air-cooled module 73 also includes air-cooled pipeline 25, and the water-cooled module 74 also includes water-cooled pipeline 26.

[0066] Reference Figure 6 and Figure 2Hydraulic pipeline 23 passes through the base plate from the output end of hydraulic pump 712 and enters the wiring space. Electrical wire 24 is connected from electrical control cabinet 723, passes through the base plate and enters the wiring space. Air-cooled pipeline 25 is connected from air tank 732, passes through the base plate and enters the wiring space. Water-cooled pipeline 26 is connected to the output end of water pump, passes through the base plate and enters the wiring space.

[0067] Reference Figure 6 and Figure 2 Hydraulic pipeline 23, electrical line 24, air-cooled pipeline 25 and water-cooled pipeline 26 are all located in the middle of the wiring space and pass through container 22. After passing through container 22, hydraulic pipeline 23, electrical line 24, air-cooled pipeline 25 and water-cooled pipeline 26 converge and connect to pneumatic rail welding machine 17.

[0068] The pipelines enter the wiring space through the bottom plate, allowing the pipelines to be arranged in an orderly manner within the container 22, improving pipeline safety and the rationality of the layout of the main control room 4; the hydraulic pipelines 23, electrical lines 24, air-cooled pipelines 25, and water-cooled pipelines 26 are connected to the pneumatic rail welding machine 17 after being gathered, allowing the pipelines to be connected to the pneumatic rail welding machine 17 in an orderly manner, improving pipeline safety; at the same time, the gathered pipelines facilitate pipeline deployment and retraction, and improve pipeline safety during transportation on the flatbed truck 1.

[0069] Reference Figure 6 and Figure 6 In this embodiment, the system also includes an acetylene pipeline 27 and an oxygen pipeline 28. The acetylene pipeline 27 is connected to the acetylene tank in the acetylene storage chamber 2 and exits through the side wall of the acetylene storage chamber 2. The oxygen tank 11 and the acetylene tank are located on the lateral sides of the flatbed 1, respectively. The acetylene pipeline 27 runs from the outer wall of the container 22 and enters the wiring space below the oxygen storage chamber 5. The oxygen pipeline 28 exits from the oxygen tank 11 and passes through the bottom plate into the wiring space. The distance between the acetylene pipeline 27 and the oxygen pipeline 28 is greater than 3 meters. After exiting the wiring space, the acetylene pipeline 27 and the oxygen pipeline 28 converge with the hydraulic pipeline 23, the electrical line 24, the air-cooled pipeline 25, and the water-cooled pipeline 26 and connect to the pneumatic rail welding machine 17.

[0070] Acetylene line 27 and oxygen line 28 are located on both sides of container 22, making the distance between acetylene line 27 and oxygen line 28 greater than 3 meters, which improves the safety of acetylene and oxygen transportation. In addition, acetylene line 27 and oxygen line 28 are connected with other lines and then connected to pneumatic rail welding machine 17, which facilitates the overall deployment and retraction of the lines and improves the safety of the lines during transportation on flatbed truck 1.

[0071] Reference Figure 7 and Figure 2In this embodiment, a mounting base 29 is provided on the flatbed 1. The mounting base 29 is fixedly mounted on the flatbed 1 and is located in front of the container 22. The take-up and take-down device 16 and the gas pressure rail welding machine 17 are both located on the mounting base 29. The collected acetylene pipeline 27, oxygen pipeline 28, hydraulic pipeline 23, electrical wiring 24, air-cooled pipeline 25, and water-cooled pipeline 26 enter the mounting base 29 and extend upwards, and are fixedly mounted on the support arm 18. The lower part of the hinge point between the support arm 18 and the telescopic mechanism is connected to the support arm 18. The system extends to the telescopic mechanism, which is equipped with a drag chain on its outer side. The collecting pipeline extending to the telescopic mechanism is connected to the pneumatic rail welding machine 17 via the drag chain. The collected pipeline is fixed on the support arm 18 and then connected to the drag chain to achieve automatic retraction and extension of the pipeline when the telescopic mechanism retracts and extends the pneumatic rail welding machine 17. In addition, the fixed point of the pipeline is located below the hinge point of the support arm 18 and the telescopic mechanism, so that the bending degree of the pipeline is controlled to a minimum when the telescopic structure pitches, thereby improving the safety of the pipeline.

[0072] To ensure a sufficient gas supply for the pneumatic rail welding machine 17, airflow manifolds are installed on the side walls of both the acetylene storage chamber 2 and the oxygen storage chamber 5. The airflow manifolds are located on the side walls of the acetylene storage chamber 2 and the oxygen storage chamber 5 respectively, with a distance of more than 3 meters between them. The airflow manifold in the acetylene storage chamber 2 is used to connect all acetylene cylinders, and the airflow manifold in the oxygen storage chamber 5 is used to connect all oxygen cylinders 11. Multiple gas cylinders are connected through the airflow manifolds, allowing multiple gas cylinders to supply gas simultaneously to meet the gas input of the pneumatic rail welding machine 17.

[0073] Reference Figure 3 , Figure 4 and Figure 2 In this embodiment, multiple explosion-proof fans 9 are provided. The explosion-proof fans 9 are arranged horizontally and located on the same horizontal plane. All multiple explosion-proof fans 9 are located above the generator 721. Because the explosion-proof fans 9 are installed above the generator 721, the heat near the generator 721 is discharged through the explosion-proof fans 9, thereby controlling the temperature in the main control room 4.

[0074] To facilitate temperature control in the main control room 4, multiple air vents are provided at the bottom of the partition plate 10, which are opened laterally along the partition plate 10. The cold air in the oxygen storage chamber 5 sinks and enters the main control room 4 through the air vents, and gradually rises along the bottom of the main control room 4 to cool the welding control components. The cold air in the oxygen storage chamber 5 enters the main control room 4 through the air vents, and the air in the main control room 4 is drawn out by the explosion-proof fan 9, so that the cold air fills the main control room 4, thereby improving the cooling effect of the equipment.

[0075] Reference Figure 3 , Figure 4 and ​In this embodiment, the air-cooled cooler 8 is connected to the hydraulic pipeline 23 and the water-cooled pipeline 26 respectively to cool the hydraulic oil and cooling water returning to the hydraulic oil tank 711 and the water tank 741.

[0076] The implementation principle of a multi-functional containerized integrated pneumatic rail welding vehicle according to an embodiment of this application is as follows:

[0077] Based on the safe storage range of oxygen and acetylene, the distance between them must be greater than 10 meters. However, due to the limitation of the overall length of the flatbed truck 1, the overall length of the flatbed truck 1 must be controlled within 12 meters. Furthermore, based on the safe storage range of acetylene, the distance between the acetylene tank and the heat source must be greater than 3 meters, and due to the length limitation of the flatbed truck 1, the distance must be controlled within 5 meters. Therefore, the length of the main control room 4 is limited to 5-9 meters. Because it is used in conjunction with the pneumatic rail welding machine 17, a large amount of equipment needs to be installed in the main control room 4, requiring creative planning of equipment placement. Since the generator 721 is large and its length exceeds the width of the main control room 4, and there are entrances on both sides of the main control room 4 for operators to enter, further consideration is needed. The door allows the generator 721 to be installed only along the length of the main control room 4. To regulate power transmission, the electrical control cabinet 723 is installed on one side of the generator 721. Meanwhile, the generator 721 generates a significant amount of heat during power generation, which can easily affect other equipment. Therefore, a maintenance passage is provided in the middle of the main control room 4 to minimize the impact on other equipment, and this passage is for maintenance personnel to access. Due to the heat effect, the hydraulic module 71, air-cooled module 73, and water-cooled module 74 are installed on the other side of the main control room 4 to ensure a distance of at least 50 centimeters between them and the generator 721, thereby reducing the temperature impact on the hydraulic module 71, water-cooled module 74, and air-cooled module 73.

[0078] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
