Description

Technical Field

[0001] The invention relates to the technical field of replenishing devices, and in particular to a modular train fuel replenishing device. Background Art

[0002] The integration of intelligent and automated technologies enables real-time monitoring and unmanned operation through sensors and data analysis, improving fuel management efficiency. In addition, the demand for environmental protection and sustainable development has prompted the device to support a variety of alternative fuels and reduce dependence on fossil fuels. With technological advancement and growing market demand, modular fuel refueling devices are expected to be more widely used around the world.

[0003] When the connectors of train fuel refueling devices are used for a long time, the distance between the connectors will increase, leading to fuel leakage, unstable connection, uneven flow, increased wear, increased maintenance costs, and reduced operational safety. These problems not only affect the normal operation and safety of the equipment, but may also cause major safety hazards such as fire. Therefore, it is very important to regularly check and adjust the distance between the connectors to ensure the normal and safe operation of the refueling device.

[0004] And when refueling, if the fuel gun is not fixed, it will cause safety hazards such as fuel leakage and fire risks, and will also cause fuel splashing, resource waste and environmental pollution. In addition, the refueling efficiency is reduced, and the operator needs to constantly hold the fuel gun, which increases the difficulty and fatigue of operation, and may cause wear and damage to the fuel gun parts. Therefore, to ensure the safety and efficiency of the refueling process, be sure to check and fix the fuel gun before refueling.

[0005] In view of the above situation, in order to overcome the above technical problems, the present invention designs a modular train fuel replenishing device to solve the above technical problems. Summary of the invention

[0006] The technical objectives to be achieved by the present invention are: to improve safety by optimizing the structure and function of the fuel nozzle to reduce fuel leakage and accidents, to improve refueling efficiency to shorten refueling time, to achieve precise control of fuel flow, and to enhance durability and reliability to ensure stable operation under various environmental conditions.

[0007] In order to achieve the above technical objectives, the present invention provides the following technical solutions: The present invention provides a modular train fuel replenishing device, comprising a base, a fuel tank, an oil pipeline, an oil outlet pipe and an oil outlet gun, wherein the fuel tank is installed above the base, the oil pipeline is installed on the left side of the fuel tank, the other end of the oil pipeline is installed with an oil outlet pipe, the other end of the oil outlet pipe is installed with a mounting gun, a fixing groove is provided on the mounting gun, and the side of the mounting gun is installed with an oil outlet gun, the fuel flow in the oil outlet gun drives the rotating ring to rotate through the inclined block, the rotating rotating ring drives the connecting pipe to rotate through the extrusion block, and the rotating connecting pipe reduces the distance between the connecting pipe and the mounting gun; and the rotating rotating ring drives the transmission ring to rotate through the clockwork, the rotating transmission ring drives the supporting block to move vertically, the vertically moving supporting block causes the extrusion column to move vertically through the rotating rod, and the vertically moving extrusion column makes the distance between the connecting pipe and the mounting gun more compact.

[0008] Through the linkage of the tilting block and the rotating ring, the device automatically adjusts the distance between the connecting pipe and the mounting gun when the fuel flows, making it closer. The rotation of the rotating ring drives the extrusion block to cooperate with the connecting pipe, reducing the possibility of loosening, ensuring the sealing during the fuel delivery process, avoiding fuel leakage, and improving safety. The support block can move vertically under the action of the transmission ring and the extrusion column, firmly fix the connecting pipe at the refueling port of the fuel tank, provide additional support, and prevent the connecting pipe from accidentally slipping out during the oil delivery process. This design reduces the risk during operation and improves the stability and reliability of the device. Since the design makes full use of the fuel flow to drive the internal mechanical linkage, it realizes automation and reduces the dependence on manual adjustment, making the fuel replenishment process more efficient and reducing the complexity of operation. During the operation, the linkage prevents the risk of accidental loosening and fuel leakage, making the fuel replenishment process safer and more reliable. In addition, the integrated design of the automatic support and sealing device reduces possible operating errors and improves overall efficiency.

[0009] The oil outlet gun includes a connecting pipe, a clamping block, an arc groove, a fixed rod, a rotating rod, a fixed spring, an extrusion column, a rotating ring, and a transmission ring. A connecting pipe is installed on the left side of the oil outlet pipe, a limiting ring is arranged inside the connecting pipe, a limiting groove is arranged on the connecting pipe on the left side of the limiting ring, a clamping groove is arranged in an array inside the limiting groove, and a clamping block is installed on the side of the connecting pipe, the cross-sectional shape of the clamping block is U-shaped, and an arc groove is arranged inside the clamping block, a fixing rod is installed on the arc groove, a rotating rod is installed on the fixing rod, a fixing spring is installed on the side of the rotating rod away from the connecting pipe interface, an extrusion column is installed on the other end of the rotating rod, a rotating ring is installed inside the limiting ring, and a transmission ring is installed on the periphery of the rotating ring.

[0010] Through the design of the limiting ring, the clamping block and the limiting groove, the connecting pipe of the oil outlet gun can be firmly positioned during the connection process to prevent the connection from loosening. At the same time, the cooperation between the clamping block and the limiting groove ensures that the oil outlet gun can maintain a seal when the fuel flows, further reducing the risk of fuel leakage. The clamping block is designed as a U-shaped structure, and an arc groove and a fixing rod are arranged inside, so that it can fit tightly with the connecting pipe during installation. The clamping block can automatically snap into the limiting groove during the flow of fuel or operation to achieve the automatic locking function, thereby improving the convenience and safety of operation. The fuel flow drives the rotating ring to rotate, and the extrusion column and the rotating rod are driven by the transmission ring to make the connection of the oil outlet gun tighter, and at the same time, pressure is applied to the connection point to further ensure the sealing. The setting of the fixed spring enables the rotating rod and the extrusion column to generate adaptive pressure regulation during the connection and installation process, and automatically adjust the tightness of the connection. This design ensures the sealing effect of the connecting pipe and the installation gun under different flow rates and pressures. The cooperation of the limiting ring, the transmission ring and the extrusion column ensures the stability of the oil outlet gun during use. The cooperation between the limit ring and the transmission ring transmits the pressure to the extrusion column through the rotating transmission ring, further consolidating the connection and preventing the connecting pipe from slipping out of the refueling port.

[0011] The cross-sectional shape of the protrusion below the rotating rod is an arc shape, and the cross-sectional shape of one end of the rotating rod close to the oil outlet pipe is a cylinder shape.

[0012] The bump under the rotating rod adopts an optimal arc cross-section design, which can maintain better fit and sealing during rotation. The optimal arc design increases the contact area, allowing it to better match with adjacent components during rotation, avoiding loose connections and ensuring stability during fuel flow. The optimal arc bump reduces friction with other components during rotation, thereby reducing wear and extending component life. In addition, the curved surface also helps the smooth flow of fuel, further reducing flow resistance and improving overall efficiency. The end of the rotating rod close to the oil outlet pipe is designed to be cylindrical, which facilitates coaxial connection with other components, ensures that there is no offset during rotation, and more accurate positioning. In addition, the cylindrical design facilitates sliding and adjustment, making the connection between the connecting pipe and the mounting gun smoother and reducing the complexity of operation. The design of the optimal arc bump and cylindrical end makes the connection and separation of the rotating rod smoother during refueling operations, reduces the difficulty of operation, and facilitates the staff to quickly install and disassemble. The optimal arc bump can be fine-tuned according to the fuel pressure during refueling to adapt to different operating environments. This adaptive adjustment function can maintain the sealing effect under different pressure conditions, ensuring that fuel will not leak and improving the safety of the device.

[0013] A transmission groove is provided on one side of the extrusion column close to the rotating rod. The shape of the left side of the transmission groove is rectangular, and the shape of the groove on the right side of the transmission groove is an arc shape. The arc shape of the groove on the right side of the transmission groove enables the transmission rod to limit the extrusion block.

[0014] The optimal arc design on the right side of the transmission groove can limit the transmission rod to ensure that the transmission rod will not deviate or disengage when the extrusion block is working. The precise limit function ensures the alignment of the components and improves the stability and safety of the entire device during the refueling operation. The rectangular design on the left side of the transmission groove provides a stable support and a large contact surface, which facilitates the effective contact between the transmission rod and the extrusion column and improves the transmission efficiency. The rectangular structure can better transmit torque, making the extrusion column more efficient when applying pressure and avoiding energy loss. The optimal arc groove has good fluidity during the transmission process and reduces the friction between the transmission rod and the extrusion block. The optimal arc design can buffer the force of the transmission rod on the extrusion block, thereby reducing wear, extending the service life of the device and improving working stability. The optimal arc groove is not only limited, but also has the characteristics of adaptive adjustment. During the refueling process, when the pressure changes, the transmission rod can fine-tune its position in the optimal arc groove, so that the pressing force of the extrusion block can be adjusted, thereby ensuring the sealing effect under different pressures. This design enhances the flexibility of the device and adapts to a variety of operating environments. The combination of rectangular and arc design ensures the transmission function while maintaining a compact structure, making the device small and fully functional. The precise control of the transmission groove on the extrusion block avoids fuel leakage and makes the sealing better.

[0015] An array of inclined plates is installed on the inner side of the rotating ring inside the limiting ring, and an array of convex grooves is opened on the inner side of the rotating ring close to the clamping groove. The position of the convex groove is the same as the height position of the clamping groove.

[0016] The inclined plate installed on the inner side of the rotating ring can provide additional driving force when the fuel flows, so that the rotating ring rotates more smoothly. This design uses fluid power to improve the rotation efficiency, so that the parts fit more closely, further improving the sealing and operational stability. The position of the convex groove is consistent with the height of the clamping groove, so that it can be accurately aligned with the clamping groove during rotation to prevent the connecting parts from slipping or detaching. The cooperation between the convex groove and the clamping groove provides a stable limiting effect, ensuring the stability of the oil gun during operation and effectively reducing the risk of loosening. The height position of the convex groove and the clamping groove is consistent, making the device more convenient to align during installation and removal, and the assembly process is faster and more accurate. The staff can achieve quick alignment without repeated adjustments during operation, which improves the operating efficiency. The design of the inclined plate not only drives the rotation, but also has the function of adaptive adjustment. When the fuel flow rate changes, the driving force of the inclined plate is adjusted accordingly, so that the rotating ring can still rotate stably under different flow rate conditions. This adaptive design ensures the reliability of the device and adapts it to different working environments. The cooperation between the convex groove and the clamping groove provides a secondary seal to prevent fuel leakage under high pressure. The driving action of the tilting plate strengthens the fit of the rotating ring, further improving the overall sealing effect and ensuring the safe delivery of fuel during refueling.

[0017] A buffer spring is clamped inside the convex groove, and an extrusion block is clamped at the other end of the buffer spring. The cross-sectional shape of the extrusion block is convex, and the upper end of the extrusion block is located inside the limiting groove. A spring is installed on the outside of the rotating ring, and one end of the outer periphery of the spring is cylindrical.

[0018] The buffer spring in the convex groove provides effective buffering during connection and operation. The spring can absorb the vibration of rotation and pressure, preventing the connection parts from loosening or being damaged due to sudden impact or vibration, thereby enhancing the durability and safety of the device. The buffer spring generates continuous squeezing force on the convex groove through the squeeze block, so that the device can maintain a tight connection during use. The convex design of the squeeze block further enhances its fit with the limit groove, and automatically makes fine adjustments during operation to ensure the stability and sealing effect of the connection. When the pressure changes during the flow of fuel, the buffer spring can automatically adjust the squeezing force according to the pressure, thereby enhancing the sealing effect. Even under high pressure or fast flow conditions, the device can maintain good sealing, avoid fuel leakage, and improve operational safety. The design of the spring provides stable support during rotation, especially its cylindrical outer end ensures uniform force distribution, so that the rotating ring rotates more smoothly. The elastic characteristics of the spring can also adapt to slight changes in rotation during rotation, ensuring the stable operation of the overall transmission system. The buffer spring and squeeze block play an important role in reducing friction and impact, significantly reducing the wear of components. At the same time, the support force provided by the mainspring to the rotating ring can reduce the wear between the rotating parts and extend the service life of the device.

[0019] A transmission ring is installed on the periphery of the rotating ring, and a buffer groove is provided in the internal array of the transmission ring. The size of the buffer groove is the same as the cylinder on the periphery of the mainspring.

[0020] The buffer groove is precisely matched with the cylindrical part of the spring, so that the transmission ring can provide a more stable buffering effect during rotation and operation, absorb vibration and impact during operation, prevent the connection parts from loosening, and improve the overall stability and durability of the device. The precise alignment of the buffer groove with the cylindrical part of the spring reduces the friction between the components, allowing the transmission ring to rotate more smoothly. This design reduces the rotation resistance, ensures the smooth operation of each transmission component during the fuel flow process, and enhances the reliability of the system. The buffer groove matches the cylindrical part of the spring, so that the transmission ring has the function of adaptive adjustment during rotation. Even under different flow rates and pressure conditions, the transmission ring and the spring can automatically adjust their buffering effect, thereby ensuring a tight connection and sealing in a variety of working environments. The buffering effect between the buffer groove and the spring reduces the direct friction between the rotating ring, the transmission ring and the spring, and reduces the risk of wear in long-term use. This design extends the life of key components, reduces maintenance and replacement costs, and improves the economy of the device. The buffer groove acts as a stable buffer area in the transmission system, reducing the shaking of components during rotation, thereby improving the sealing performance. The solid operation of the drive ring reduces the risk of fuel leaks due to looseness or deviation, making refueling safer.

[0021] The side array of the transmission ring is provided with an adjustment groove, the cross-sectional shape of the adjustment groove is an arc, an adjustment rod is installed inside the adjustment groove, an adjustment block is installed on the adjustment rod, a support block is installed on the periphery of the adjustment block, the cross-sectional shape of the support block is an arc, and one end of the support block is located below one end of the rotating rod.

[0022] One end of the support block is located below the rotating rod, providing additional support force to ensure that the entire device is more stable during the refueling process. The arc-shaped cross-section of the support block can fit precisely with the rotating rod, further increasing the stability of the support and effectively preventing deviation or shaking during operation. The arc-shaped cross-section of the adjustment slot cooperates with the adjustment rod to enable the adjustment rod and the adjustment block to be accurately adjusted. The sliding of the adjustment block in the adjustment slot enables fine-tuning of the support block position, which is convenient for adjusting the size of the support force as needed, thereby improving the adaptability of the device in different operating environments. The arc-shaped design of the support block allows it to fit more closely with other components in the transmission system, helping to maintain a sealed state during operation. The additional support and stability provided by the support block reduces the risk of fuel leakage and ensures the safety of the refueling process. The sliding characteristics of the adjustment rod and the adjustment block in the adjustment slot enable the support block to automatically adjust its position according to different pressures, providing better support effects. This adaptive adjustment function improves the stability of the device under different flow rates and pressure conditions and reduces dependence on manual operation. The design of the arc-shaped adjustment slot and the adjustment rod reduces friction during rotation and movement, protecting the components of the adjustment system from wear. The arc-shaped fit between the support block and the rotating rod reduces direct friction, helps extend the service life of the device and reduces maintenance costs. The reasonable layout of the adjustment slot, adjustment rod and support block makes the entire device compact and functionally integrated, reduces unnecessary components, saves space, and improves the convenience of installation and disassembly, making it suitable for wide application in various refueling equipment.

[0023] The beneficial effects of the present invention are as follows: 1. The U-shaped clamping block is designed with an arc groove and a fixing rod inside, so that it can fit tightly with the connecting pipe during installation. The clamping block can automatically snap into the limit groove during fuel flow or operation to achieve automatic locking function, thereby improving the convenience and safety of operation. The fuel flow drives the rotating ring to rotate, and the rotating ring drives the extrusion column and the rotating rod, so that the oil nozzle and the connection point are further tightly combined, and pressure is applied to the connection point to further ensure the sealing.

[0024] 2. The elegant arc design on the right side of the transmission slot limits the transmission rod, ensuring that the transmission rod will not deviate or disengage when the extrusion block is working. The precise limit function ensures the alignment of the components and improves the stability and safety of the entire device during refueling operations. The rectangular design on the left side of the transmission slot provides a solid support and a large contact surface, which facilitates effective contact between the transmission rod and the extrusion column, thereby improving transmission efficiency.

[0025] 3. The inclined plate installed on the inner side of the rotating ring can provide additional driving force when the fuel flows, making the rotating ring rotate more smoothly. This design uses fluid power to improve the rotation efficiency, so that the various components fit more closely, further improving the sealing and operational stability. The position of the convex groove is consistent with the height of the clamping groove, so that it can be precisely aligned during the rotation process to prevent the connecting parts from slipping or detaching.

[0026] 4. The arc-shaped cross-section of the support block can fit precisely with the rotating rod, further enhancing the stability of the support and effectively preventing deviation or shaking during operation. The arc-shaped cross-section of the adjustment groove cooperates with the adjustment rod, so that the adjustment rod and the adjustment block can be precisely adjusted. The sliding of the adjustment block in the adjustment groove realizes the fine adjustment of the position of the support block, which is convenient for adjusting the size of the supporting force as needed, thereby improving the adaptability of the device in different operating environments.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. The embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figure 1 , 2 , 3, 4, 5, 6, 7, 8 and 9, a modular train fuel replenishing device provided by the present invention comprises a base 1, a fuel tank 2, an oil pipeline 3, an oil outlet pipe 4 and an oil outlet gun 5, wherein the fuel tank 2 is installed above the base 1, the fuel tank 2 is installed on the left side of the fuel tank 2, the oil pipeline 3 is installed at the other end of the fuel pipeline 3, the oil outlet pipe 4 is installed at the other end of the oil outlet pipe 4, the installation gun 41 is provided with a fixing groove 42, the side of the installation gun 41 is installed with the oil outlet gun 5, and the fuel in the oil outlet gun 5 flows through The rotating ring 58 is driven to rotate by the tilting block, and the rotating rotating ring 58 drives the connecting tube 51 to rotate through the squeezing block 584, and the rotating connecting tube 51 reduces the distance between it and the mounting gun 41; and the rotating rotating ring 58 drives the transmission ring 59 to rotate through the spring 585, and the rotating transmission ring 59 drives the supporting block 595 to move vertically, and the vertically moving supporting block 595 makes the squeezing column 57 move vertically through the rotating rod 55, and the vertically moving squeezing column 57 makes the distance between the connecting tube 51 and the mounting gun 41 more compact.

[0032] Through the linkage of the tilting block and the rotating ring 58, the device can automatically adjust the distance between the connecting pipe 51 and the mounting gun 41 when the fuel flows, making them closer. The rotation of the rotating ring drives the extrusion block 584 to cooperate with the connecting pipe 51, reducing the possibility of loosening, ensuring the sealing during the fuel delivery process, avoiding fuel leakage, and improving safety. The support block 595 can move vertically under the action of the transmission ring 59 and the extrusion column 57, firmly fix the connecting pipe 51 to the refueling port of the fuel tank 2, provide additional support, and prevent the connecting pipe 51 from accidentally slipping out during the oil delivery process. This design reduces the risk during operation and improves the stability and reliability of the device. The design makes full use of the internal mechanical linkage driven by the fuel flow to achieve automation, reduce the dependence on manual adjustment, make the fuel replenishment process more efficient, and reduce the complexity of operation. During the operation, the linkage mechanism effectively prevents the risk of accidental loosening and fuel leakage, making the fuel replenishment process safer and more reliable. In addition, the integrated design of the automatic support and sealing device reduces possible operating errors and improves overall efficiency.

[0033] like Figure 1 , 2 , 3, 4, 5, 6, 7 and 8, the oil outlet gun 5 includes a connecting pipe 51, a clamping block 52, an arc groove 53, a fixing rod 54, a rotating rod 55, a fixing spring 56, an extrusion column 57, a rotating ring 58, and a transmission ring 59. The connecting pipe 51 is installed on the left side of the oil outlet pipe 4, and a limiting ring 511 is provided inside the connecting pipe 51. A limiting groove 512 is provided on the connecting pipe 51 on the left side of the limiting ring 511, and a clamping groove 513 is provided in an array inside the limiting groove 512, and the connecting pipe A clamping block 52 is installed on the side of 51, and the cross-sectional shape of the clamping block 52 is U-shaped, and an arc groove 53 is opened inside the clamping block 52, a fixing rod 54 is installed on the arc groove 53, and a rotating rod 55 is installed on the fixing rod 54. A fixing spring 56 is installed on the side of the rotating rod 55 away from the interface of the connecting pipe 51, and an extrusion column 57 is installed on the other end of the rotating rod 55. A rotating ring 58 is installed inside the limiting ring 511, and a transmission ring 59 is installed on the periphery of the rotating ring 58.

[0034] Through the design of the limiting ring 511, the clamping block 52 and the limiting groove 512, the connecting pipe 51 of the oil outlet gun 5 can be firmly positioned during the connection process to prevent the connection from loosening. At the same time, the cooperation between the clamping block 52 and the limiting groove 512 ensures that the oil outlet gun 5 remains sealed when the fuel flows, further reducing the risk of fuel leakage. The clamping block 52 is designed as a U-shaped structure, and an arc groove 53 and a fixing rod 54 are arranged inside, so that it can fit tightly with the connecting pipe 51 during the installation process. During the flow of fuel or operation, the clamping block 52 can automatically snap into the limiting groove 512 to achieve an automatic locking function, thereby improving the convenience and safety of operation. The flow of fuel drives the rotating ring 58 to rotate, and drives the extrusion column 57 and the rotating rod 55 through the transmission ring 59, so that the connection of the oil outlet gun 5 is tighter, and pressure is applied to the connection point to further ensure the sealing. The setting of the fixing spring 56 enables the rotating rod 55 and the extrusion column 57 to adaptively adjust the pressure during the connection and installation process, and automatically adjust the tightness of the connection. This design ensures the sealing effect of the connecting pipe 51 and the mounting gun 41 under different flow rates and pressures. The cooperation of the limiting ring 511, the transmission ring 59 and the extrusion column 57 ensures the stability of the oil discharge gun 5 during use. The cooperation of the limiting ring 511 and the transmission ring 59 transmits the pressure to the extrusion column 57 by rotating the transmission ring 59, further consolidating the connection and preventing the connecting pipe 51 from slipping out of the oil filling port.

[0035] like Figure 4 and 6 As shown, the cross-sectional shape of the protrusion below the rotating rod 55 is an arc shape, and the cross-sectional shape of one end of the rotating rod 55 close to the oil outlet pipe 4 is a cylinder.

[0036] The protrusion under the rotating rod 55 adopts an optimal arc cross-section design, which can maintain better fit and sealing during the rotation process. The optimal arc design increases the contact area, so that it can better match with adjacent components during rotation, avoid loose connections, and ensure stability during the flow of fuel. At the same time, the optimal arc protrusion reduces the friction with other components during rotation, thereby reducing wear and extending the service life of the components. In addition, the arc surface helps the smooth flow of fuel, further reduces flow resistance, and improves overall efficiency. The end of the rotating rod 55 close to the oil outlet pipe 4 is designed to be cylindrical, which is convenient for coaxial connection with other components, ensuring that there is no offset during rotation and more accurate positioning. The cylindrical design is also convenient for sliding and adjustment, making the connection between the connecting pipe 51 and the installation gun 41 smoother and reducing the complexity of operation. The design of the optimal arc protrusion and the cylindrical end makes the connection and separation of the rotating rod 55 smoother during the refueling operation, reduces the difficulty of operation, and facilitates the staff to quickly install and disassemble. The optimal arc protrusion can be fine-tuned according to the fuel pressure during refueling to adapt to different operating environments. This adaptive adjustment function can maintain a good sealing effect under different pressure conditions, ensuring that fuel will not leak and improving the safety of the device.

[0037] like Figure 6 As shown, a transmission groove 571 is provided on one side of the extrusion column 57 close to the rotating rod 55. The shape of the left side of the transmission groove 571 is rectangular, and the shape of the groove on the right side of the transmission groove 571 is an arc shape. The arc shape of the groove on the right side of the transmission groove 571 enables the transmission rod to limit the extrusion block 584.

[0038] The superior arc design on the right side of the transmission groove 571 exerts a limiting effect on the transmission rod, ensuring that the transmission rod will not deviate or disengage when the extrusion block 584 is working. The precise limiting function ensures the alignment of the components and improves the stability and safety of the entire device during the refueling operation. The rectangular design on the left side of the transmission groove 571 provides a stable support and a large contact surface, which facilitates the effective contact between the transmission rod and the extrusion column 57, thereby improving the transmission efficiency. The rectangular structure can better transmit torque, making the extrusion column 57 more efficient when applying pressure and avoiding energy loss. The superior arc groove 53 has good smoothness during the transmission process, reducing the friction between the transmission rod and the extrusion block 584. The superior arc design can buffer the force of the transmission rod on the extrusion block 584, thereby reducing wear, extending the service life of the device, and improving working stability. The superior arc groove 53 not only has a limiting function, but also has the characteristics of adaptive adjustment. During the refueling process, when the pressure changes, the transmission rod can fine-tune its position in the superior arc groove 53, so that the pressing force of the extrusion block 584 can be adjusted, thereby ensuring the sealing effect under different pressures. This design enhances the flexibility of the device and adapts to a variety of operating environments. The combination of the rectangular and arc-shaped design ensures the transmission function while maintaining a compact structure, making the device small and fully functional. The precise control of the transmission groove 571 on the extrusion block 584 effectively avoids fuel leakage and further improves the sealing performance.

[0039] like Figure 7 As shown, an inclined plate 581 is installed in an array on the inner side of the rotating ring 58 inside the limiting ring 511, and a convex groove 582 is opened in an array on the inner side of the rotating ring 58 close to the snap-in groove 513. The position of the convex groove 582 is the same as the height position of the snap-in groove 513.

[0040] The inclined plate 581 installed on the inner side of the rotating ring 58 can provide additional driving force when the fuel flows, so that the rotating ring 58 rotates more smoothly. This design uses fluid power to improve the rotation efficiency, so that the components fit more closely, further improving the sealing and operational stability. The position of the convex groove 582 is consistent with the height of the clamping groove 513, so that it can be accurately aligned during the rotation process to prevent the connecting parts from sliding or detaching. The cooperation between the convex groove 582 and the clamping groove 513 provides a stable limiting effect, ensuring the stability of the oil gun 5 during operation and effectively reducing the risk of loosening. The consistency of the height position of the two makes it easier to align the device during installation and disassembly, thereby speeding up the assembly process and improving accuracy. During operation, the staff can achieve rapid alignment without repeated adjustments, further improving the operating efficiency. The design of the inclined plate 581 not only drives the rotation, but also has an adaptive adjustment function. When the fuel flow rate changes, the driving force of the inclined plate 581 will be adjusted accordingly, so that the rotating ring 58 can still rotate stably under different flow rate conditions. This adaptive design ensures the reliability of the device and adapts it to different working environments. The cooperation between the convex groove 582 and the clamping groove 513 provides a secondary seal, effectively preventing the leakage of fuel under high pressure. At the same time, the driving action of the inclined plate 581 strengthens the fitting force of the rotating ring 58, further improving the overall sealing effect and ensuring the safe delivery of fuel during the refueling process.

[0041] like Figure 8 and 9 As shown, a buffer spring 583 is clamped inside the convex groove 582, and an extrusion block 584 is clamped at the other end of the buffer spring 583. The cross-sectional shape of the extrusion block 584 is convex, and the upper end of the extrusion block 584 is located inside the limiting groove 512. A spring 585 is installed on the outer side of the rotating ring 58, and one end of the outer periphery of the spring 585 is cylindrical.

[0042] The buffer spring 583 in the convex groove 582 provides an effective buffering effect during the connection and operation process. The spring can absorb the vibration caused by rotation and pressure, prevent the connection parts from loosening or being damaged due to sudden impact or vibration, thereby enhancing the durability and safety of the device. The buffer spring 583 applies a continuous extrusion force to the convex groove 582 through the extrusion block 584, so that the device can maintain a tight connection when in use. The convex design of the extrusion block 584 further enhances its fit with the limit groove 512, ensuring that it can be automatically fine-tuned during operation, thereby ensuring the stability of the connection and the sealing effect. During the flow of fuel, if there is a pressure change, the buffer spring 583 can automatically adjust the extrusion force according to the pressure, thereby enhancing the sealing effect. Even under high pressure or fast flow conditions, the device can maintain good sealing, avoid fuel leakage, and improve the safety of operation. The design of the clockwork 585 provides a stable support force during the rotation process, especially its cylindrical outer end ensures a uniform distribution of force, so that the rotating ring 58 rotates more smoothly. The elastic properties of the spring 585 can also adapt to slight rotation changes during the rotation process, ensuring the stable operation of the overall transmission system. The buffer spring 583 and the extrusion block 584 play an important role in reducing friction and impact, significantly reducing the wear of the components. At the same time, the support force provided by the spring 585 to the rotating ring 58 can reduce the wear between the rotating components and extend the service life of the device.

[0043] like Figure 8 and 9 As shown, a transmission ring 59 is installed on the periphery of the rotating ring 58 , and a buffer groove 591 is opened in the internal array of the transmission ring 59 . The size of the buffer groove 591 is the same as the cylinder on the periphery of the mainspring 585 .

[0044] The setting of the buffer groove 591 is precisely matched with the cylindrical part of the spring 585, so that the transmission ring 59 can provide a more stable buffering effect during rotation and operation, absorb vibration and impact during operation, prevent the connection parts from loosening, and improve the overall stability and durability of the device. The precise alignment of the buffer groove 591 with the cylindrical part of the spring 585 reduces the friction between the components, so that the transmission ring 59 can rotate more smoothly. This design reduces the rotation resistance, ensures the smooth operation of each transmission component during the flow of fuel, and enhances the reliability of the system. The buffer groove 591 matches the cylindrical part of the spring 585, so that the transmission ring 59 has the function of adaptive adjustment when rotating. Even under different flow rates and pressure conditions, the transmission ring 59 and the spring 585 can automatically adjust their buffering effects, thereby ensuring tight connection and sealing in a variety of working environments. The buffering effect between the buffer groove 591 and the spring 585 reduces the direct friction between the rotating ring 58, the transmission ring 59 and the spring 585, and reduces the risk of wear in long-term use. This design extends the life of key components, reduces maintenance and replacement costs, and improves the economic efficiency of the device. The buffer groove 591 acts as a stable buffer area in the transmission system, reducing the shaking of components during rotation, thereby improving the sealing performance. The stable operation of the transmission ring 59 reduces the risk of fuel leakage caused by looseness or deviation, making fuel replenishment safer.

[0045] like Figure 8 and 9 As shown, the side array of the transmission ring 59 is provided with an adjustment groove 592, the cross-sectional shape of the adjustment groove 592 is an arc, an adjustment rod 593 is installed inside the adjustment groove 592, an adjustment block 594 is installed on the adjustment rod 593, a support block 595 is installed on the periphery of the adjustment block 594, the cross-sectional shape of the support block 595 is an arc, and one end of the support block 595 is located below one end of the rotating rod 55.

[0046] One end of the support block 595 is located below the rotating rod 55, providing additional support force to ensure that the entire device is more stable during the refueling process. The arc-shaped cross-section of the support block 595 can be precisely fitted with the rotating rod 55, further increasing the stability of the support and effectively preventing deviation or shaking during operation. The arc-shaped cross-section of the adjustment slot 592 cooperates with the adjustment rod 593, so that the adjustment rod 593 and the adjustment block 594 can be precisely adjusted. The sliding of the adjustment block 594 in the adjustment slot 592 realizes the fine adjustment of the position of the support block 595, which is convenient for adjusting the size of the support force as needed, thereby improving the adaptability of the device in different operating environments. The arc-shaped design of the support block 595 makes it fit more closely with other components in the transmission system, which helps to maintain a sealed state during operation. The additional support and stability provided by the support block 595 reduces the risk of fuel leakage and ensures the safety of the refueling process. The sliding characteristics of the adjustment rod 593 and the adjustment block 594 in the adjustment slot 592 enable the support block 595 to automatically adjust its position according to different pressures, providing a better support effect. This adaptive adjustment function improves the stability of the device under different flow rates and pressure conditions and reduces dependence on manual operation. The design of the arc-shaped adjustment slot 592 and the adjustment rod 593 reduces friction during rotation and movement, protecting the components of the adjustment system from wear. The arc-shaped fit between the support block 595 and the rotating rod 55 reduces direct friction, helps to extend the service life of the device and reduce maintenance costs. The reasonable layout of the adjustment slot 592, the adjustment rod 593 and the support block 595 makes the entire device compact and functionally integrated, reduces unnecessary components, saves space, and improves the convenience of installation and disassembly, making it suitable for wide application in various refueling equipment.

[0047] During the working process of the present invention, the staff first installs the installation gun 41 on the oil outlet pipe 4 and the connecting pipe 51 on the oil outlet gun 5, puts the installed safety gun and the oil outlet gun 5 into the train's refueling tank 2, and pushes the inclined plate 581 through the flow of fuel. Since the inclined plate 581 is designed to be inclined, the inclined plate 581 will drive the rotating ring 58 to rotate, and the rotating rotating ring 58 will drive the connecting pipe 51 to rotate through the side extrusion block 584. The rotating connecting pipe 51 can be better connected to the installation gun 41 tightly, preventing the staff from loosening the connection port during use, thereby causing the fuel to flow out; the rotating ring 58 drives the clockwork 585 to rotate while rotating, and the clockwork 585 The transmission ring 59 is driven to rotate through its own elasticity, and the rotating transmission ring 59 rotates together with the side adjustment groove 592. The adjustment groove 592 drives the adjustment rod 593 to move while rotating, and the moving adjustment rod 593 drives the adjustment block 594 to move vertically, so that the vertically moving adjustment block 594 drives the support block 595 to expand outward, thereby supporting the refueling port of the refueling tank 2 to prevent the connecting pipe 51 from slipping out of the refueling tank 2 during the refueling process, and the support block 595 will also squeeze the rotating rod 55 when it expands outward, so that the squeezing block 584 can be better squeezed into the fixed groove 42, so that the installation gun 41 and the connecting pipe 51 are tighter, thereby avoiding the outflow of fuel.

The terms used in the appended claims should not be construed to limit the invention to the specific embodiments disclosed in the specification.
