Description

Technical Field

[0001] This invention relates to the field of railway turnout spraying and maintenance technology, and in particular to railway turnout spraying equipment. Background Technology

[0002] A railway turnout can be understood as a branching point on a railway line. It is a track connection device that allows trains to switch from one set of tracks to another. It enables locomotives and rolling stock to change from traveling on one track to one of two or more tracks after passing a track intersection. At the intersection of railway lines, turnouts are used to change the direction of the connection. In the past, switchmen moved the turnouts manually. Now, high-speed railways use electronically controlled turnouts. Each turnout consists of a switch, a switch point, two guard rails, a sleeper, and a slide plate. The two movable rails are moved by a long handle using the lever principle. The slide plate is the core component of the railway turnout system. It is located below the switch rail and stock rail assembly and mainly undertakes the functions of translation support and load transfer during switch rail switching. When the two movable rails are moved, the movable rails are moved and adjusted on the slide plate.

[0003] Currently, to ensure the smooth sliding of the moving track on the slide plate, it is necessary to manually clean the oil stains and rust on the surface of the slide plate regularly, and then apply new maintenance lubricant. Before applying the new maintenance lubricant, it is necessary to wait for the residual water on the slide plate to dry. This waiting time extends the working time. In addition, the workers apply the maintenance lubricant by brushing, which is labor-intensive and further reduces work efficiency.

[0004] Therefore, we propose a railway turnout spraying equipment to solve the above problems. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a spraying device for railway turnouts, so as to solve the problems mentioned in the background technology, such as the need to wait for the slide plate to air dry naturally after cleaning, which leads to extended working time, and the large workload and low efficiency of manual application of lubricating oil.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The spraying equipment for railway turnouts includes oil supply equipment and air supply equipment, as well as air pipe, oil pipe A, oil pipe B and spray nozzle. Oil pipe A and oil pipe B are located in the air pipe. The bottom of the air pipe is connected to an air spray box. The spray nozzle is connected to oil pipe B and is located in the air spray box.

[0008] The air tube is fitted with a heating box that is locked in place. The inner wall of the heating box is provided with a pressure ring A and a heating wire. The air tube is provided with baffles A, B, and C and is located in the heating box. The air tube is provided with through holes A, B, and D. The baffle B is provided with through hole C.

[0009] There is an air storage chamber and a heating chamber between the heating box and the air pipe. The air pipe is provided with a separator A and a separator B. Separator A and separator B form an oil chamber in the air pipe. Through hole B connects to the oil chamber. Oil pipe A is screwed to separator A and oil pipe B is screwed to separator B.

[0010] Preferably, the heating box includes cone box A and cone box B arranged opposite each other, and the opposite ends of cone box A and cone box B are through round holes. Pressure ring A is connected to the inner wall of cone box A. After cone box A and cone box B are respectively fitted onto the outside of the air pipe through the round holes, cone box A is slid downward outside the air pipe so that the top position of cone box A contacts baffle plate A. Then cone box B is slid upward outside the air pipe so that the bottom position of cone box B contacts baffle plate C. In this state, the opposite ends of cone box A and cone box B are in contact together. Then cone box A and cone box B are locked together by bolts. In this way, the top position of cone box A is pressed against the surface of baffle plate A, pressure ring A is pressed against the top of baffle plate B near the outer ring, and the bottom position of cone box B is pressed against the surface of baffle plate C. Thus, an air storage chamber is formed between baffle plate A and baffle plate B and is located between cone box A and air pipe. Through hole A and through hole B are opened on the air pipe. Through hole A connects the air storage chamber and the air pipe.

[0011] Preferably, a heating chamber is formed between the baffle B and the baffle C and is located between the cone box B and the air pipe. The through hole C connects the air storage chamber and the heating chamber. The heating wire is connected to the inner wall of the cone box B. The heating wire can heat the environment in the heating chamber so that the gas entering and passing through becomes hot. The through hole D connects the air pipe and the heating chamber, and the position of the through hole D connecting the air pipe is located below the separator B.

[0012] Preferably, the separator A includes a connecting disc portion A and an internally threaded cylinder portion A, with the internally threaded cylinder portion A connected to the top middle position of the connecting disc portion A, and an oil hole A is provided through the connecting disc portion A and communicates with the internally threaded cylinder portion A. The separator B includes a connecting disc portion B and an internally threaded cylinder portion B, with the internally threaded cylinder portion B connected to the bottom middle position of the connecting disc portion B, and an oil hole B is provided through the connecting disc portion B and communicates with the internally threaded cylinder portion B.

[0013] Preferably, a through hole is provided in the middle of the bottom of the jet box, and a plurality of jet holes A are provided in the bottom of the jet box. The plurality of jet holes A are distributed in a circle around the through hole and are arranged in a ring. A plurality of jet holes B are provided on the side of the jet box. The jet holes A and jet holes B are used to spray the gas in the jet box.

[0014] The fuel injector is fitted with a sealing ring and locked with screws. When the fuel injector is located in the fuel injection box and the bottom part of the fuel injector is inserted through the through hole, the sealing ring is pressed against the bottom of the fuel injection box. This ensures that the fuel injector is stable in the fuel injection box and also prevents air leakage between the fuel injector and the fuel injection box through the through hole.

[0015] Preferably, the gas pipe is provided with an oil-gas control structure, and the oil-gas control structure includes a control component and a venting ring. The control component is sleeved on the oil pipe B and located in the lower part of the gas pipe. The control component includes a connector and a movable pressure component. The connector includes a connecting ring connected to the internally threaded cylindrical part B, and at least three connecting rods are provided on the outer ring of the connecting ring. The movable pressure component includes a conical plug, and a conical ring is connected to the top ring of the conical plug. A limiting ring is provided in the conical plug through a connecting block. The control component also includes a return spring connected between the connector and the movable pressure component. The top part of the return spring is connected to the connecting rod, and the bottom part of the return spring is connected to the conical ring. The return spring, the conical ring, and the limiting ring are sleeved on the oil pipe B.

[0016] The ventilation ring includes a ring portion B and a ring portion A connected as one piece in an upper and lower position. The diameter of the ring portion B is smaller than the diameter of the ring portion A, and a ventilation opening is provided on the ring portion B that penetrates the ring portion A. The ventilation opening is used to allow gas from the lower part of the air pipe to pass through and enter the jet box.

[0017] Preferably, the cone plug includes a hopper, a straight passage, and a pressure ring B. The hopper is a cylindrical shape with a larger upper opening and a smaller lower opening. The straight passage has the same upper and lower diameters and is connected to the smaller diameter end of the hopper. The inner ring diameter of the pressure ring B is connected to the straight passage and the smaller diameter of the hopper. The cone-shaped ring is connected inside the larger diameter end of the hopper.

[0018] Preferably, the side of the jet box is provided with multiple sets of roller brush assemblies, and the roller brush assembly includes two lugs connected to the jet box. A shaft is rotatably connected between the two lugs. A roller is sleeved on the shaft and locked with screws. A bristle group is arranged on the outer ring of the roller. Two impellers are sleeved on the shaft. The two impellers are respectively connected to the two ends of the roller and correspond to the jet hole B. The impeller is composed of a ring plate and multiple blades. The multiple blades are arranged in a circle on the ring plate and are all in an inclined state. The ring plate is sleeved on the shaft and connected to the end of the roller.

[0019] Preferably, the fuel injector is provided with a cleaning assembly on its exterior and located at the bottom of the jet box. The cleaning assembly includes a drive wheel and a scraper and a brush rod disposed on the drive wheel. The drive wheel includes an inner ring, an outer ring, and guide plates. The inner ring is located in the outer ring. Several guide plates are inclined and evenly connected between the inner ring and the outer ring. The inner ring is rotatably sleeved on the outside of the fuel injector. Several guide plates are located below a ring of jet holes A. The scraper and brush rod are both connected to the bottom of the inner ring and the outer ring.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] This system integrates drying and spraying, improving operational efficiency. By setting up a coordinated structure of heating box, air jet box, and oil spray head, it can quickly dry the moisture on the slide plate surface using heated high-pressure gas before spraying lubricating oil. Then, it automatically switches to the oil spraying state, realizing integrated "drying-spraying" operation. This avoids the time wasted by waiting for the moisture to evaporate naturally in the traditional way, significantly shortens the maintenance cycle, and improves operational efficiency.

[0022] To achieve oil heating and insulation and ensure lubrication effect, the oil pipes are arranged inside the heating chamber and air pipe. The heating wires are used to heat and insulate the oil in the oil chamber and oil pipes, which effectively prevents the oil from condensing or decreasing its fluidity in low temperature environment. This ensures that the oil is always in a suitable fluid state for spraying, improves the adhesion and lubrication effect of the lubricating oil, and ensures the smooth movement of the turnout track.

[0023] It achieves automatic control of the spraying rhythm, is simple and reliable to operate. By setting up an oil and gas control structure, it can automatically control the alternation of air jet and oil spray according to the gas pressure, realizing an automated cycle of "blowing hot air first and then spraying oil". No manual intervention is required for switching, making it easy to operate, highly reliable, and reducing labor intensity.

[0024] Equipped with self-cleaning and auxiliary coating functions, the equipment is more practical. The roller brush assembly on the side of the spray box can use the airflow to drive the impeller to rotate the brush bristles, so as to achieve uniform coating of the sprayed oil. At the same time, centrifugal force is used to remove residual oil and prevent the brush bristles from clumping. The cleaning assembly can automatically clean the spray nozzle during the spraying process to prevent the oil hole from being blocked, ensuring the coating quality and long-term stable operation of the equipment.

[0025] In summary, the railway turnout spraying equipment provided by this invention integrates drying, heating, spraying, coating and self-cleaning functions, effectively solving the problems of long waiting time, high labor intensity and inability to keep warm and lubricate existing technologies, and has significant technological progress and practical value.

[0041] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0042] Reference Figure 1-6 The spraying equipment for railway turnouts includes an oil supply system and an air supply system, as well as an air pipe 10, an oil pipe A20, an oil pipe B30, and an oil nozzle 40. The air pipe 10 is used to discharge the gas supplied by the air supply system. The oil pipes A20 and B30 are connected and used to discharge the oil supplied by the oil supply system. The oil pipes A20 and B30 are located within the air pipe 10. An air jet box 60 is connected to the bottom of the air pipe 10. The oil nozzle 40 is connected to the oil pipe B30 and is located within the air jet box 60. A heating box 50 is fitted and locked onto the outside of the air pipe 10, and a pressure ring A is provided on the inner wall of the heating box 50. 511 and heating wire 521, the air pipe 10 is provided with baffles A11, B14 and C16 on the outside and located in the heating box 50, and the air pipe 10 is provided with through holes A12, B13 and D15 on the outside, and through hole C141 on the baffle B14. There is an air storage chamber and a heating chamber between the heating box 50 and the air pipe 10. The air pipe 10 is provided with partitions A17 and B18, which form an oil chamber in the air pipe 10. Through hole B13 connects to the oil chamber. Oil pipe A20 is screwed to partition A17 and oil pipe B30 is screwed to partition B18.

[0043] Reference Figure 1-5The railway turnout painting equipment includes a heating box 50 comprising two cone boxes, A51 and B52, arranged opposite each other. The opposite ends of cone boxes A51 and B52 are through-holes. A pressure ring A511 is connected to the inner wall of cone box A51. After cone boxes A51 and B52 are respectively fitted onto the outside of air pipe 10 through the holes, cone box A51 is slid downwards outside air pipe 10, so that the top of cone box A51 contacts baffle plate A11. Then, cone box B52 is slid upwards outside air pipe 10, so that the bottom of cone box B52 contacts baffle plate C16. In this state, the opposite ends of cone boxes A51 and B52 are in contact. Then, cone boxes A51 and B52 are locked together with bolts. Thus, the top of cone box A51 is pressed against the surface of baffle plate A11, and pressure ring A511 is pressed against baffle plate B52. At the top of cone box B52, near the outer ring, the bottom of cone box B52 is pressed against the surface of baffle plate C16, thus forming an air storage chamber between baffle plate A11 and baffle plate B14, located between cone box A51 and air pipe 10. Air pipe 10 has through holes A12 and B13. Through hole A12 connects the air storage chamber and air pipe 10. When the air supply device supplies air to air pipe 10, filling the upper part of air pipe 10 with gas, the gas enters the air storage chamber through through hole A12. The gas in the air storage chamber enters the heating chamber through through hole C141. When the gas pressure in the air storage chamber increases, the gas enters the oil chamber through through hole B13. Through hole A12 has a one-way valve A to prevent gas from flowing back into air pipe 10, and through hole B13 has a one-way valve B to prevent oil in the oil chamber from flowing back into the air storage chamber.

[0044] Reference Figure 1-4 The railway turnout spraying equipment has a heating chamber formed between baffles B14 and C16 and located between cone box B52 and air pipe 10. Through hole C141 connects the air storage chamber and the heating chamber. Heating wire 521 is connected to the inner wall of cone box B52. Heating wire 521 can heat the environment in the heating chamber, so that the gas entering and passing through becomes hot. Through hole D15 connects air pipe 10 and heating chamber, and the position of through hole D15 connecting air pipe 10 is below the separator B18. When the gas in the air storage chamber enters the heating chamber through through hole C141 and becomes hot, it enters the lower part of air pipe 10 through through hole D15. The gas in the lower part of air pipe 10 enters the jet box 60 and is filled, and then is sprayed out from jet hole A62 and jet hole B63. The hot gas sprayed out dries the moisture on the slide plate in the railway turnout, thereby improving the effect of subsequent spraying of oil on the slide plate.

[0045] Reference Figure 5 , 6The railway turnout painting equipment includes a separator A17 comprising a connecting disc A and an internally threaded cylinder A, with the internally threaded cylinder A connected to the top center of the connecting disc A. An oil hole A171 is provided through the connecting disc A and communicates with the internally threaded cylinder A. A separator B18 comprises a connecting disc B and an internally threaded cylinder B, with the internally threaded cylinder B connected to the bottom center of the connecting disc B. An oil hole B181 is provided through the connecting disc B and communicates with the internally threaded cylinder A. In cylindrical section B, the top and bottom of the oil chamber formed between separator A17 and separator B18 are respectively penetrated by oil holes A171 and B181. When the end of oil pipe A20 away from the oil supply equipment is screwed into the internally threaded cylindrical section A, oil pipe A20 connects to the oil chamber through oil hole A171. When the end of oil pipe B30 away from the injector head 40 is screwed into the internally threaded cylindrical section B, oil pipe B30 connects to the oil chamber through oil hole B181. When the oil supply equipment supplies oil to the oil pipe... In A20, the oil falls into the oil chamber through oil hole A171 and accumulates there. Then, the oil in the oil chamber enters the oil pipe B30 through oil hole B181, and then enters the spray nozzle 40 from the oil pipe B30 and is sprayed out. Since the oil chamber is located in the heating chamber, the heating chamber heats the oil chamber and the oil inside it while heating the gas. At the same time, when the heated gas enters the lower part of the air pipe 10, the oil pipe B30 is kept warm by the heated gas in the lower part of the air pipe 10. At the same time, the spray nozzle 40 is also kept warm by the heated gas in the spray box 60. This ensures that the oil is in a smooth fluid state and prevents the oil from flowing slowly or even forming lumps in the oil pipe. This ensures the normal delivery and supply of oil and sprays it out from the spray nozzle 40 onto the slide plate in the railway turnout, preventing the lubrication from being affected and thus preventing the movement of the moving track in the railway turnout from being affected on the slide plate.

[0046] Reference Figure 2 , 6 8, 11, Spraying equipment for railway turnouts, a through hole 61 is provided in the middle of the bottom of the spray box 60, and several spray holes A62 are provided in the bottom of the spray box 60. The spray holes A62 are distributed in a circle around the through hole 61. Multiple sets of spray holes B63 are provided on the side of the spray box 60. The spray holes A62 and B63 are used to spray the gas in the spray box 60. The spray box 60 is screwed to the bottom of the air pipe 10. The oil nozzle 40 is screwed to the bottom of the oil pipe B30. A sealing ring 41 is provided on the outside of the oil nozzle 40 and locked with screws. When the oil nozzle 40 is located in the spray box 60 and the bottom part of the oil nozzle 40 is inserted through the through hole 61, the sealing ring 41 is pressed against the bottom of the inner end of the spray box 60. This can ensure that the oil nozzle 40 is stable in the spray box 60 and prevent air leakage between the oil nozzle 40 and the spray box 60 through the through hole 61.

[0047] Reference Figure 5-9The spraying equipment for railway turnouts includes an oil-gas control structure in the air pipe 10. This structure comprises a control component 70 and a ventilation ring 80. The control component 70 is sleeved on the oil pipe B30 and located in the lower part of the air pipe 10. The control component 70 includes a connector 72 and a movable pressure component 73. The connector 72 includes a connecting ring 721 connected to the internally threaded cylindrical part B, and at least three connecting rods 722 are provided on the outer ring of the connecting ring 721. The movable pressure component 73 includes a cone plug 731, with a conical ring 732 connected to the top of the cone plug 731. A limiting ring 733 is provided in the cone plug 731 via a connecting block. Component 70 also includes a return spring 71 connected between the connector 72 and the movable pressure member 73. The top part of the return spring 71 is connected to the connecting rod 722, and the bottom part of the return spring 71 is connected to the conical ring 732. The return spring 71, the conical ring 732, and the limiting ring 733 are sleeved on the oil pipe B30. The venting ring 80 includes a ring portion B82 and a ring portion A81 connected together in an upper and lower position. The diameter of the ring portion B82 is smaller than the diameter of the ring portion A81, and a venting opening 821 is provided on the ring portion B82 that penetrates the ring portion A81. The venting opening 821 is used to allow gas in the lower part of the air pipe 10 to pass through and enter the jet box 60.

[0048] When the heated gas enters the lower part of the air pipe 10 through the through hole D15, it impacts the movable pressure member 73. Under the impact of the gas pressure, because the cone plug 731 is approximately trumpet-shaped, when the gas pressure accumulates in the large-diameter end and cannot be discharged downwards in time from the small-diameter end, the gas will press the cone plug 731 downwards and slide it. That is, the cone plug 731 slides downwards on the oil pipe B30 and stretches the return spring 71. At the same time, the gas rushes into the bottom end of the air pipe 10, and then rushes into the jet box 60 from the vent opening 821 and is ejected from the jet hole. When the cone plug 731 slides downwards in the air pipe 10 until its bottom end presses against the vent ring member 80, the cone plug... The bottom end of 731 is pressed into contact with the top of the ring B82 and blocks the vent opening 821. This prevents the gas in the air pipe 10 from continuing to be discharged, resulting in excessive pressure in the lower part of the air pipe 10. Furthermore, the pressure in the heating chamber is also high, as is the pressure in the gas storage chamber. Under these circumstances, the excessive gas pressure causes the gas to be discharged from the through hole B13 into the oil chamber, thereby pressurizing the oil chamber. Since the oil hole A171 is equipped with a one-way valve C to prevent the backflow of oil in the oil pipe A20, when the upper part of the oil chamber is pressurized, the oil in the lower half of the oil chamber is squeezed out from the oil pipe B30 into the injector head 40 and sprayed out under the pressure.

[0049] Then, the operator stops supplying air to the air pipe 10, causing a decrease in pressure in the upper part of the air pipe 10. As gas enters the oil chamber, the pressure in the heating chamber also decreases, and the pressure in the lower part of the air pipe 10 also decreases. The cone plug 731 is no longer subjected to pressure, and under the contraction and convergence of the return spring 71, the cone plug 731 moves upward and slides back to its original position near the connector 72 outside the oil pipe B30. At this point, the vent opening 821 is exposed. Then, the operator supplies air to the air pipe 10. The gas enters the air storage chamber from the upper part of the air pipe 10 and then enters the lower part of the air pipe 10 through the through hole C141. The gas entering the lower part of the air pipe 10 presses the cone plug 731 downward, causing it to slide. Simultaneously, the cone plug 731 slides downward on the oil pipe B30, stretching the return spring 71. The gas rushes towards the bottom of the air pipe 10 and then rushes into the jet box 60 through the vent opening 821. When the cone plug 731 slides down in the air pipe 10 until its bottom end presses against the vent ring 80, the bottom end of the cone plug 731 presses against the top of the ring B82 and blocks the vent opening 821. This prevents the gas in the air pipe 10 from continuing to escape, causing excessive pressure in the lower part of the air pipe 10. This further increases the pressure in the heating chamber and the gas storage chamber. Under this condition, the excessive gas pressure causes the gas to be discharged from the through hole B13 into the oil chamber, thereby pressurizing the oil chamber. Under the action of pressure, the oil in the oil chamber is squeezed from the oil pipe B30 into the oil nozzle 40 and sprayed out. In this operating state, high-pressure hot air is sprayed out to dry the slide plate in the railway turnout, and then oil is sprayed out onto the slide plate in the railway turnout. This eliminates the need to manually dry the slide plate first and then apply oil, and also eliminates the need to wait for the slide plate to dry naturally, saving processes and time, and improving the efficiency of oil spraying.

[0050] Reference Figure 9 The spraying equipment for railway turnouts includes a cone plug 731 comprising a bucket 7311, a straight section 7312, and a pressure ring B7313. The bucket 7311 is a cylindrical shape with a larger upper opening and a smaller lower opening. The straight section 7312 has the same upper and lower diameters and is connected to the smaller diameter end of the bucket 7311. The inner ring diameter of the pressure ring B7313 is connected to the smaller diameter of both the straight section 7312 and the bucket 7311. The cone ring 732 is connected to the larger diameter end of the bucket 7311. During use, the cone ring 732 and the bucket 7311 can withstand the impact of the airflow and change the speed at which the airflow impacts downwards. This allows the airflow to apply pressure to the cone plug 731 as it impacts downwards, causing the cone plug 731 to slide downwards. The pressure ring B7313 presses against the ring section B82 and blocks the ventilation opening 821.

A spraying device for railway turnouts, wherein the side of the spray box 60 is provided with multiple sets of roller brush assemblies 90, and the roller brush assembly 90 includes two lugs 91 connected to the spray box 60, and a shaft 921 is rotatably connected between the two lugs 91. A roller 922 is sleeved on the shaft 921 and locked with screws. Brush bristle groups 923 are arranged on the outer ring of the roller 922. Two impellers 93 are sleeved on the shaft 921, and the two impellers 93 are respectively connected to the two ends of the roller 922, and the two impellers 93 correspond to the spray holes B63 respectively. The impeller 93 consists of a ring plate and multiple blades. The multiple blades are arranged circumferentially on the ring plate, and the multiple blades are all in an inclined state. The ring plate is sleeved on the shaft. The roller brush assembly 90 is connected to the end of the roller 922. After the oil is sprayed onto the slide plate, the oil can be manually applied by the brush bristles 923 in the roller brush assembly 90 to improve the contact and adhesion between the oil and the slide plate surface. In addition, when the oil is sprayed out from the jet hole B63, the high-pressure airflow blows onto the blades in the impeller 93, causing the impeller 93 to rotate, which in turn drives the roller 922 to rotate. The roller 922 drives the brush bristles 923 to rotate, which can also automatically apply the oil sprayed onto the slide plate. After the roller brush application is completed, the oil on the brush bristles 923 can be thrown away by centrifugal force to prevent the oil from adhering to the brush bristles 923 and to prevent it from drying and affecting the next use.

The cleaning assembly 100 includes a drive wheel and scraper 104 and brush 105 mounted on the drive wheel. The drive wheel includes an inner ring 101, an outer ring 102, and guide plates 103. The inner ring 101 is located within the outer ring 102. Several guide plates 103 are inclined and evenly connected between the inner ring 101 and the outer ring 102. The inner ring 101 is rotatably sleeved outside the spray nozzle 40. Several guide plates 103 are located below a ring of air jet holes A62. The scraper 104... Both the 04 and the brush rod 105 are connected to the bottom of the inner ring 101 and the outer ring 102. When the jet nozzle A62 sprays out high-pressure airflow, the airflow hits several guide plates 103, causing the drive wheel to rotate outside the fuel injector 40. The drive wheel drives the scraper rod 104 and the brush rod 105 to rotate. The scraper rod 104 can scrape the oil stains that may exist at the bottom of the fuel injector 40. The brush bristles on the brush rod 105 clean the bottom of the fuel injector 40 and unclog the fuel injection holes at the bottom of the fuel injector 40, so that any clumps of oil stains that may exist in the holes can be cleaned to prevent them from affecting the fuel spraying.
