Description

Technical Field

[0001] The invention relates to the technical field of continuous spraying of railway contact networks, and in particular to an online continuous spraying device for electrified railway contact network conductors. Background Art

[0002] During the actual use of the electrified railway contact network wire, certain materials will be sprayed regularly, such as wear-resistant materials, conductive grease and anti-oxidation coating according to the needs. Due to the frequent friction between the contact network wire and the pantograph slide, wear-resistant materials will be sprayed to reduce the wear of the wire. For example, nano-ceramic coating has the characteristics of high hardness and low friction coefficient. During the contact process, this coating can effectively resist the friction of the pantograph slide, like a layer of solid "armor" to protect the contact network wire. In addition, the nano-ceramic coating has good chemical stability and can maintain good performance under different climatic conditions, greatly extending the service life of the contact network wire. The main function of the contact network is to supply power to the train, so good conductivity must be ensured. Conductive grease can play a lubricating role without affecting the transmission of current. It contains conductive components such as metal particles, such as silver powder, which can fill the tiny gaps that may exist on the surface of the contact network wire, so that the current can pass smoothly, while reducing problems such as electric sparks caused by poor contact, and ensuring the stability of the train's power supply. The contact network wire is usually made of metal and is easily oxidized with oxygen in the air. For example, copper wires will gradually generate copper oxide in the air. Spraying an anti-oxidation coating can prevent this from happening. Like silicone anti-oxidation coating, it can form a dense protective film on the surface of the conductor to prevent oxygen from contacting the conductor. This film has good flexibility and will not break due to thermal expansion and contraction of the conductor, thereby effectively protecting the conductor from oxidation for a long time. In the prior art, no matter what material is sprayed, there are problems of complex spraying, low efficiency and poor effect. Therefore, it is very necessary to design an online continuous spraying device for electrified railway contact network conductors to improve the spraying efficiency and spraying effect of the contact network conductors.

[0048] Example 1

[0049] Reference Figure 1~Figure 4The present embodiment proposes an online continuous spraying device for electrified railway contact network conductors, which is used for spraying materials on the railway contact network, including a traveling vehicle 1, which is used for traveling on the rails; a support frame 2 is arranged on the traveling vehicle 1; a sliding member 3 is slidably arranged on the supporting frame 2, and the sliding direction is perpendicular to the length direction of the rails; a guide wheel 4 is rotatably arranged on the sliding member 3, and the guide wheel 4 has a wheel groove 401, and the wheel groove 401 is used for guiding on the railway contact network; a spray head 5 is arranged on the sliding member 3, and is located on one side of the guide wheel 4 and faces the railway contact network.

[0050] In this embodiment, the traveling vehicle 1 is used as a basic moving component, and its design principle is to utilize the cooperation between the wheels and the rails to stably travel on the rails. In actual work, the traveling vehicle 1 moves along the rails, driving the entire device to operate along the railway. The support frame 2 is installed on the traveling vehicle 1 to provide support and installation foundation for the sliding member 3. Its design purpose is to ensure that the sliding member 3 can slide stably in the direction perpendicular to the length of the rail. The sliding member 3 is slidably arranged on the support frame 2, and the position of the guide wheel 4 and the nozzle 5 is adjusted by sliding. This design is well adapted to the zigzag railway contact network wire, ensuring that the guide wheel 4 and the nozzle 5 can accurately contact the wire and perform spraying operations. The guide wheel 4 is rotatably arranged on the sliding member 3, and its wheel groove 401 is used for guiding on the railway contact network. The design principle is to ensure that the device maintains stable guidance during movement and prevents deviation from the spraying position through the cooperation between the wheel groove 401 and the contact network wire. The nozzle 5 is arranged on the sliding member 3 and is located on one side of the guide wheel 4 and facing the railway contact network. Its working principle is to spray the spray material onto the contact network wire at a certain pressure and angle to achieve uniform spraying.

[0051] For example, in an actual spraying operation, the traveling vehicle 1 moves forward along the rails, and according to the zigzag shape of the contact wire, the positions of the guide wheel 4 and the nozzle 5 are adjusted so that the wheel groove 401 of the guide wheel 4 can always accurately clamp the contact wire for guidance, and at the same time, the nozzle 5 sprays the spray material to the wire to complete the continuous spraying operation. In terms of technical effects, this structural design enables the device to automatically travel along the railway and perform continuous spraying operations, which improves the spraying efficiency and reduces the complexity and uncertainty of manual operation. It can adapt to the contact wire, ensure the accuracy and uniformity of the spraying, and thus improve the spraying effect.

[0052] Overall working principle: The traveling vehicle 1 drives the entire device to move on the rails, the sliding member 3 is adjusted according to the position of the contact wire, the guide wheel 4 realizes the guidance, and the nozzle 5 performs the spraying, and together completes the online continuous spraying operation of the railway contact wire. Overall technical effect: It effectively solves the problems of complex spraying, low efficiency and poor effect in the existing technology, improves the spraying efficiency and spraying quality of the contact wire, and provides a guarantee for the safe and stable operation of the electrified railway.

[0053] Furthermore, the support frame 2 includes a support arm 201, which is arranged on the traveling vehicle 1; a swing arm 202 is swingably arranged on the support arm 201; one end of a torsion spring 203 acts on the support arm 201, and the other end acts on the swing arm 202, providing a force for the swing arm 202 to swing upward, wherein the support arm 201 has an arc-shaped guide groove 204, and the rotation axis of the arc-shaped guide groove 204 is coaxial with the axis of swing of the swing arm 202, and the swing arm 202 has a guide portion 205, which is slidably arranged in the arc-shaped guide groove 204, and the two ends of the arc-shaped guide groove 204 are respectively an upper limit portion 206 and a lower limit portion 207.

[0054] In this embodiment, the support arm 201 is installed on the traveling vehicle 1 to provide a mounting base for the swing arm 202. The swing arm 202 is swingably set on the support arm 201, and its design principle is to adapt to different working conditions and environments by swinging. One end of the torsion spring 203 acts on the support arm 201, and the other end acts on the swing arm 202, providing a force for the swing arm 202 to swing upward. Its function is to keep the swing arm 202 in a certain initial position when there is no external force. The rotation axis of the arc guide groove 204 on the support arm 201 is coaxial with the axis of the swing arm 202. The guide part 205 of the swing arm 202 is slidably set in the arc guide groove 204. The two ends of the arc guide groove 204 are the upper limit part 206 and the lower limit part 207 respectively. The design principle is to limit the swing range of the swing arm 202 through the cooperation of the arc guide groove 204 and the guide part 205 to ensure that it moves within a safe and effective range.

[0055] In actual work, for example, when the height of the contact network conductor changes suddenly, the swing arm 202 will swing downward under the action of the conductor to overcome the force of the torsion spring 203, and the guide part 205 slides in the arc guide groove 204. When the external force disappears, the force of the torsion spring 203 causes the swing arm 202 to swing upward until the guide part 205 hits the upper limit part 206. In terms of technical effects, the swing design of the swing arm 202 and the coordination of the torsion spring 203 improve the adaptability of the device to the change of the height of the contact network conductor. The setting of the arc guide groove 204 and the guide part 205 ensures the stability and reliability of the movement of the swing arm 202.

[0056] Overall working principle: During the movement of the traveling vehicle 1, the swing arm 202 swings within a certain range according to the actual situation of the contact wire, always ensuring that the sliding member 3, the guide wheel 4 and the spray head 5 can accurately contact the wire and perform operations. Overall technical effect: Through the synergistic effect of the above structure, the working performance of the device is further optimized, the adaptability to different working conditions is improved, and the continuity and stability of the spraying operation are guaranteed.

[0057] Furthermore, the support frame 2 further includes a support platform 208 , which is rotatably disposed on the upper end of the swing arm 202 , and the sliding member 3 is slidably disposed on the support platform 208 .

[0058] In this embodiment, the support platform 208 is rotatably arranged at the upper end of the swing arm 202. The design principle is to provide a rotatable support platform for the slider 3, which increases the flexibility of adjusting the position of the slider 3. In actual work, when the device moves along the rails and encounters a change in the direction of the contact network wire, the support platform 208 can be rotated accordingly to ensure the appropriate angle and approach, thereby driving the slider 3 and the guide wheel 4 and the nozzle 5 thereon to adjust the angle to better adapt to the position and direction of the wire. Ensure that the wheel groove 401 of the guide wheel 4 is always in good contact with the wire, and the nozzle 5 can also maintain a suitable spraying angle to achieve accurate and uniform spraying. In terms of technical effects, the rotation design of the support platform 208 improves the adaptability of the device to complex line conditions and further ensures the quality and effect of spraying.

[0059] Overall working principle: During the travel of the traveling vehicle 1, the swing arm 202 swings according to the height of the conductor, the support platform 208 rotates according to the direction of the conductor, and the sliding member 3 slides on the support platform 208 to adjust its position, thereby achieving accurate tracking and spraying of the contact wire by the guide wheel 4 and the spray head 5. Overall technical effect: Through this multi-dimensional adjustment method, the versatility and work efficiency of the device are significantly improved, and the spraying problem under different line conditions is effectively solved, providing reliable technical support for the high-quality spraying of the contact wire of the electrified railway.

[0060] Example 2

[0061] Reference Figure 5~Figure 8 In this embodiment, based on the first embodiment, the support frame 2 further includes a connecting rod 209, one end of the connecting rod 209 is hinged to the support arm 201, and the other end is hinged to the support platform 208, and the hinge position is configured so that the connecting rod 209, the swing arm 202, the support arm 201 and the support platform 208 form a parallel four-bar linkage mechanism, so that the support platform 208 can continuously remain horizontal.

[0062] In this embodiment, one end of the connecting rod 209 is hinged to the support arm 201, and the other end is hinged to the support platform 208. The design principle is to utilize the characteristics of the parallel four-bar linkage mechanism to ensure that the support platform 208 can continue to remain horizontal during the movement. In actual work, when the swing arm 202 swings and the support platform 208 rotates, since the connecting rod 209, the swing arm 202, the support arm 201 and the support platform 208 constitute a parallel four-bar linkage mechanism, no matter how other components move, the support platform 208 can always remain horizontal.

[0063] For example, when the device encounters uneven rails or changes in the position of the contact wire, causing the swing arm 202 and the support platform 208 to change their angles and positions, due to the effect of the parallel four-bar linkage, the sliding member 3, the guide wheel 4 and the nozzle 5 on the support platform 208 always remain horizontal, and the effect and accuracy of the spraying will not be affected by the tilt. In terms of technical effects, the design of this parallel four-bar linkage ensures that the nozzle 5 can horizontally align with the contact wire for spraying under various working conditions, thereby improving the uniformity and quality stability of the spraying.

[0064] Overall working principle: During the operation of the device, the swing of the swing arm 202, the rotation of the support platform 208 and the coordinated movement of the connecting rod 209 enable the support platform 208 to always remain horizontal during the complex movement process, providing a guarantee for the stable spraying of the nozzle 5. Overall technical effect: Through this stable structural design, the reliability and spraying effect of the device are effectively improved, adapting to different railway line conditions, and ensuring high-quality spraying operations of electrified railway contact network conductors.

[0065] Furthermore, the railway overhead line is divided into several sections, and two adjacent sections are of different phases and are connected with a phase-splitting insulator 6, the phase-splitting insulator 6 has an insulating component 601 and a guide 602, the guide 602 is located on both sides of the insulating component 601, and the lower end is lower than the insulating component 601, and the guide 602 is used to guide the pantograph of the train to pass, and also includes:

[0066] The rotating push piece 7 is rotatably arranged on the traveling vehicle 1, and the axial direction of rotation of the rotating push piece 7 is vertical. The rotating push piece 7 has a pushed portion 701, and the position of the pushed portion 701 is configured to be located on the outside of the guide member 602, and is used to be pushed and rotated by the outside of the guide member 602. The rotating push piece 7 also has a first inclined surface 702, and the support platform 208 has a second inclined surface 210. The first inclined surface 702 abuts against the second inclined surface 210, so as to realize pressing down the support platform 208 after the rotating push piece 7 rotates.

[0067] In this embodiment, the railway contact network is composed of several sections, and a phase-splitting insulator 6 is connected between two adjacent sections. The guide member 602 of the phase-splitting insulator 6 is located on both sides of the insulating component 601 and the lower end is lower than the insulating component 601, which is used to guide the train pantograph to pass. The rotating push member 7 is rotatably arranged on the traveling vehicle 1, and its pushed part 701 is located on the outside of the guide member 602. The design principle is that when the traveling vehicle 1 passes through the phase-splitting insulator 6, the guide member 602 can push the pushed part 701 to rotate the rotating push member 7. The first inclined surface 702 of the rotating push member 7 abuts against the second inclined surface 210 of the support platform 208. The working principle is that when the rotating push member 7 rotates, the first inclined surface 702 and the second inclined surface 210 cooperate to press down the support platform 208.

[0068] In actual operation, when the device moves along the rail and encounters the phase-splitting insulator 6, the guide member 602 pushes the pushed portion 701 of the rotating push member 7, causing the rotating push member 7 to rotate. As the rotating push member 7 rotates, its first inclined surface 702 acts on the second inclined surface 210 of the support platform 208, thereby pressing the support platform 208 downward. For example, when the traveling vehicle 1 is about to pass through the phase-splitting insulator 6, the guide member 602 contacts the pushed portion 701 and pushes the rotating push member 7 to rotate. The rotation of the rotating push member 7 causes the first inclined surface 702 to press down the second inclined surface 210, and the support platform 208 descends accordingly, driving the sliding member 3, the guide wheel 4 and the nozzle 5 to descend, avoiding collision or interference with the phase-splitting insulator 6. In terms of technical effects, this design can automatically adjust the height of the support platform 208 when the device passes through the phase-splitting insulator 6, protecting the device from damage, while ensuring the continuity and stability of the spraying work.

[0069] Overall working principle: During the operation of the traveling vehicle 1, when encountering the phase-splitting insulator 6, the guide member 602 pushes the rotating push member 7 to rotate, and then presses down the support platform 208, so that the nozzle 5 and other components avoid the phase-splitting insulator 6, and return to the normal position after passing through, and continue the spraying operation. Overall technical effect: Through this ingenious design, the avoidance problem of the device when passing through the phase-splitting insulator 6 is effectively solved, the adaptability and reliability of the device are improved, and the smooth spraying of the electrified railway contact network conductor is ensured.

[0070] Furthermore, the pushed portion 701 is in the form of a vertical plate, and is composed of a plurality of vertical plates arranged in an arc shape in sequence, so as to avoid being stuck on the guide member 602 .

[0071] In this embodiment, the pushed part 701 is designed as a vertical plate type, and several of them are arranged in an arc shape in sequence. The design principle is that the vertical plate type structure can more directly receive the thrust of the guide member 602, and the arc shape arrangement can adapt to the thrust at different angles, reducing the possibility of collision and jamming. In actual work, when the traveling vehicle 1 passes through the phase-splitting insulator 6, due to the vertical plate type and arc shape arrangement design of the pushed part 701, even if the pushing direction of the guide member 602 changes, the pushed part 701 can smoothly receive the thrust and rotate the rotating pusher 7 without getting stuck on the guide member 602. The use of the vertical plate type and arc shape arrangement of the pushed part 701 can ensure that it can interact smoothly with the guide member 602 under various circumstances, and will not get stuck between the two guide members 602, so as to realize the accurate rotation of the rotating pusher 7 and the subsequent downward pressing operation of the support platform 208. In terms of technical effect, this special design of the pushed part 701 improves the reliability and stability of the cooperation between the device and the phase-splitting insulator 6, and reduces the probability of failure.

[0072] Overall working principle: The traveling vehicle 1 drives the rotating pusher 7 to approach the phase-splitting insulator 6, and the arc-shaped vertical plate-type pushed part 701 contacts the guide part 602 stably, smoothly transmitting the thrust to the rotating pusher 7, causing it to rotate and press down the support platform 208. Overall technical effect: By optimizing the structure of the pushed part 701, the performance and stability of the online continuous spraying device for the overhead contact wire of the electrified railway are further improved in actual operation, ensuring the uninterrupted and high-quality spraying work.

[0073] Furthermore, the nozzle 5 is slidably arranged on the sliding member 3, and the sliding direction is perpendicular to the sliding direction of the sliding member 3. It also includes a first elastic member 8, one end of the first elastic member 8 acts on the nozzle 5, and the other end acts on the sliding member 3, providing a force to move the nozzle 5 away from the guide wheel 4; the second elastic member 9 and the third elastic member 10 are respectively arranged on both sides of the guide wheel 4 and act on the guide wheel 4, providing a force to center the guide wheel 4 between the second elastic member 9 and the third elastic member 10.

[0074] In this embodiment, the nozzle 5 is slidably arranged on the sliding member 3, and the sliding direction is perpendicular to the sliding direction of the sliding member 3. The principle of this design is to allow the nozzle 5 to be fine-tuned in the vertical direction to better adapt to the position and shape of the contact network wire. One end of the first elastic member 8 acts on the nozzle 5, and the other end acts on the sliding member 3, providing a force for the nozzle 5 to move away from the guide wheel 4. Its function is to keep the nozzle 5 in the initial position when there is no external force, and to provide a certain buffering and reset ability when subjected to external force. The second elastic member 9 and the third elastic member 10 are respectively arranged on both sides of the guide wheel 4 and act on the guide wheel 4, providing a force to center the guide wheel 4 between the two. Its design purpose is to ensure that the guide wheel 4 can remain in a stable middle position when subjected to the pressure of the contact network wire, thereby improving the accuracy and stability of the guidance.

[0075] In actual work, for example, when the position of the contact network wire has a slight deviation or an irregular shape, the nozzle 5 will overcome the force of the first elastic member 8 under the action of the wire and approach the guide wheel 4, so as to better align the wire for spraying. At the same time, the guide wheel 4 will move within a certain range under the pressure of the wire, and the elastic force of the second elastic member 9 and the third elastic member 10 will make the guide wheel 4 always tend to the center position to ensure the stability of the guide. In terms of technical effects, the sliding of the nozzle 5 and the setting of the first elastic member 8 improve the position adaptability of the nozzle 5, and can spray more accurately. The elastic members on both sides of the guide wheel 4 ensure the centering stability of the guide wheel 4 and improve the guiding effect.

[0076] Overall working principle: During the operation of the device, the nozzle 5 and the guide wheel 4 can be adaptively adjusted according to the actual situation of the contact network wire, and maintain a good working state under the action of the elastic parts, so as to achieve continuous and accurate spraying and guiding. Overall technical effect: Through these elastic parts and sliding design, the working accuracy and stability of the device are significantly improved, which better meets the online continuous spraying requirements of the contact network wire of the electrified railway.

[0077] Furthermore, it also includes a feed pipe 11, which is arranged on the support platform 208 and connected to the nozzle 5, and a valve 12 is arranged on the feed pipe 11. The first gear 13 and the second gear 14 are meshed with each other and are respectively arranged on the valve stem of the valve 12 and the rotating push piece 7.

[0078] In this embodiment, the feed pipe 11 is arranged on the support platform 208 and is connected to the nozzle 5, and is used to deliver the spraying material to the nozzle 5. The valve 12 is arranged on the feed pipe 11, and is used to control the flow rate of the spraying material. The first gear 13 and the second gear 14 are meshed with each other, and are respectively arranged on the valve stem of the valve 12 and the rotating push piece 7. The design principle is that when the rotating push piece 7 rotates, the valve stem of the valve 12 is driven to rotate through the gear transmission, thereby controlling the opening and closing degree of the valve 12.

[0079] In actual operation, when the traveling vehicle 1 passes through the phase-splitting insulator 6 and the rotating pusher 7 is pushed and rotated by the guide member 602, the second gear 14 drives the first gear 13 to rotate, thereby adjusting the opening and closing of the valve 12. For example, the rotating pusher 7 rotates to close the valve 12 or reduce the flow rate, thereby avoiding unnecessary spraying when passing through the phase-splitting insulator 6. In terms of technical effects, this gear linkage design realizes automatic control of the flow rate of the spraying material according to the operating state of the device, improves the utilization rate of the material, and reduces waste.

[0080] Overall working principle: During the travel of the traveling vehicle 1, when encountering the phase-splitting insulator 6, the rotation of the rotating push piece 7 controls the valve 12 through the gear transmission, adjusts the flow of the spraying material in the feeding pipe 11, and restores the normal spraying flow after passing. Overall technical effect: Through this automatic flow control design, the performance of the device is further optimized, the efficiency and economy of the spraying are improved, and the spraying quality of the electrified railway contact network conductor is guaranteed.

[0081] Furthermore, there are two nozzles 5, which are respectively located on both sides of the railway contact network, and also include a shield 15, which is arranged on the nozzle 5, and the lower part of the shield 15 has a material storage space.

[0082] In this embodiment, two nozzles 5 are provided, which are respectively located on both sides of the railway contact network. The principle of this design is to spray the contact network from both sides at the same time, which can cover the spraying material more comprehensively and evenly, and improve the spraying effect and efficiency. The shield 15 is provided on the nozzle 5, and the lower part of the shield 15 has a material storage space. Its design purpose is to prevent the splashing and waste of the spraying material, and at the same time, the material storage space can collect the excess material that is not completely attached to the contact network for secondary use.

[0083] In actual work, the two nozzles 5 work simultaneously to spray the contact network on both sides. The shield 15 effectively limits the diffusion range of the spraying material, so that most of the material is concentrated near the contact network. The storage space collects the falling material and reduces the waste of material. For example, when the nozzle 5 sprays out the material, the shield 15 prevents the material from splashing around at will, making the spraying work more concentrated and efficient. At the same time, the material that falls into the storage space can be processed and used again for spraying, saving costs. In terms of technical effects, the setting of the double-sided nozzles 5 improves the uniformity and speed of spraying, the shield 15 reduces the waste of materials and environmental pollution, and the storage space realizes the recycling of materials.

[0084] Overall working principle: When the device is running, the two nozzles 5 spray on both sides of the contact network at the same time, and the shield 15 controls the spraying range and uses the storage space to collect excess materials, so as to achieve efficient and economical spraying operation. Overall technical effect: Through these designs, the spraying quality and economic benefits of the electrified railway contact network wire are significantly improved, while reducing the impact on the environment.

[0085] Furthermore, rotating pushers 7 are provided on both sides of the support platform 208 .

[0086] In this embodiment, rotating pushers 7 are provided on both sides of the support platform 208. The design principle is to receive the thrust from the guide member 602 of the phase-splitting insulator 6 from both sides at the same time, so that the downward pressing action of the support platform 208 is more stable and reliable. In actual operation, when the traveling vehicle 1 passes through the phase-splitting insulator 6, the rotating pushers 7 on both sides of the support platform 208 are pushed by the guide member 602 at the same time. In this way, the force is more evenly distributed on the support platform 208, avoiding the tilt or instability that may be caused by the force on one side.

[0087] For example, if only one side is provided with the rotating push piece 7, when the push force is applied, the support platform 208 may be laterally offset, affecting the position and working effect of the nozzle 5 and other components. However, after the rotating push piece 7 is provided on both sides, the support platform 208 can be pressed down steadily no matter from which direction the guide member 602 is contacted. In terms of technical effect, the provision of the rotating push piece 7 on both sides improves the stability and accuracy of the movement of the support platform 208, reduces the failures and errors caused by uneven force, and further ensures the continuity and quality of the spraying work.

[0088] Overall working principle: When the traveling vehicle 1 encounters the phase-splitting insulator 6 during its travel, the rotating pushers 7 on both sides of the support platform 208 are pushed synchronously, and the support platform 208 is pressed down together, so that the nozzle 5 and other components can smoothly avoid the phase-splitting insulator 6. Overall technical effect: By arranging the rotating pushers 7 on both sides of the support platform 208, the adaptability and working reliability of the device under complex working conditions are effectively enhanced, providing a stronger guarantee for the efficient and accurate spraying of the electrified railway contact network wire.
