Description

Technical Field

[0001] The invention relates to the technical field of sand adding devices, in particular to a sand adding device for high-speed railways. Background Art

[0002] The purpose of adding sand to high-speed trains is to prevent wheels from spinning or slipping under certain circumstances and ensure the safety of trains. Specifically, when high-speed trains are climbing a slope or encountering bad weather, the friction between the wheels and the rails may decrease, causing the wheels to spin or slip. In order to increase the friction between the wheels and the rails, high-speed trains will use sand to avoid this.

[0003] In recent years, in order to improve the efficiency of sand adding, a high-pressure air pump automatic sand loading machine has been used to add sand to high-speed railways. When in use, the low-pressure gas from the outside is first sucked into the high-pressure air pump, and then the high-pressure air pump begins to compress. After the gas is compressed to a certain pressure, the high-pressure air pump transports the compressed gas to the sand bin in the sand loading machine, and then the sand is driven by the high-pressure gas and sprayed out through a specific pipe or nozzle.

[0004] In the prior art, during the use of the high-pressure air pump type automatic sand loading machine, the sand and gravel carried by the high-pressure airflow can easily cause serious air pollution, and the pump body, valve and other components used to transport the sand and gravel are severely worn by the sand and gravel, resulting in the equipment being damaged after a certain period of use, and frequent maintenance or replacement of parts is required, which increases the cost of adding sand. In addition, the quartz sand used in high-speed trains has certain requirements on the particle size of the quartz sand. Quartz sand with a smaller particle size does not meet the anti-skid effect required by the train during braking, so the quartz sand needs to be filtered to avoid a large amount of unqualified quartz sand when adding sand, thereby affecting the braking of the train. Summary of the invention

[0043] The material storage assembly 3 includes a material storage bin 31; a material delivery port 22 is provided on the side wall of the material delivery bin 21; and the material delivery port 22 is arranged through the material storage bin 31;

[0044] During operation, in the prior art, during the use of the high-pressure air pump type automatic sanding machine, the sand and gravel carried by the high-pressure airflow can easily cause serious air pollution, and the pump body, valve and other components used to transport the sand and gravel are seriously worn by the sand and gravel, resulting in the equipment being damaged after a certain period of use, and frequent maintenance or replacement of parts is required, which increases the cost of adding sand, and the quartz sand used in high-speed trains has certain requirements on the particle size of the quartz sand. The quartz sand with a smaller particle size cannot meet the anti-skid effect required by the train during braking, so the quartz sand needs to be filtered to avoid it during adding. When the train is adding sand, a large amount of unqualified quartz sand appears, which affects the braking of the train. In order to prevent such incidents from happening, first, the quartz sand is loaded into the storage bin 31, and then the quartz sand in the storage bin 31 will reach the feeding bin 21 through the feeding port 22. When the train needs to add sand, the mobile vehicle 1 is driven to the sand box of the train, and then the discharge pipe 243 is rotated, and the discharge pipe 243 is rotated to the sand inlet of the sand box, and then the vertical auger 25 in the feeding bin 21 is driven to rotate. When rotating, the vertical auger 25 transports the quartz sand in the feeding bin 21 to the top of the vertical conveying bin 23. After reaching the top, the quartz sand will slide from the transfer pipe 26 on the side wall of the vertical conveying bin 23 to the horizontal conveying bin 24. After reaching the horizontal conveying bin 24, the quartz sand is transported to the discharge box 242 by the horizontal auger 241, and then enters the train sand box through the discharge pipe 243. When the vertical auger 25 rotates, the first connecting shaft 254 can be driven to rotate, so that the first gear 255 and the transmission belt 256 can be used to drive the second gear 245 below to rotate. The second gear 245 is fixedly connected to the output end of the horizontal auger 241. When the vertical auger 25 rotates, the first gear 255 and the transmission belt 256 can be used to drive the second gear 245 below to rotate. The wheel 255 and the second gear 245 drive the horizontal auger 241 to rotate, realizing vertical and horizontal transportation, thereby transporting the quartz sand from the feed bin 21 to the discharge box 242. Through the setting of the first gear 255 and the second gear 245, the two groups of augers can be driven to rotate at the same time, and the rotation speed of the horizontal auger 241 can be adjusted according to the rotation speed of the vertical auger 25 to achieve the purpose of rapid sand addition, thereby improving the efficiency of sand addition, and through the setting of the vertical conveying bin 23 and the horizontal conveying bin 24, the quartz sand can be prevented from being exposed to the air and causing air pollution.

[0045] like Figure 3 and Figure 6 As shown, the end of the vertical auger 25 away from the feeding bin 21 is fixedly connected to a driving gear 252; the side wall of the vertical conveying bin 23 is rotatably connected to a transmission gear 253; the transmission gear 253 is meshed and connected with the driving gear 252; the output end of the transmission gear 253 is fixedly connected to the first connecting shaft 254;

[0046] When working, the vertical auger 25 rotates, which drives the driving gear 252 to rotate, thereby driving the transmission gear 253 to rotate. The transmission gear 253 is fixedly connected to the first connecting shaft 254, thereby driving the first gear 255 to rotate through the first connecting shaft 254. Through the setting of the first gear 255 and the transmission belt 256, the horizontal auger 241 is driven to rotate, thereby realizing the transportation of quartz sand.

[0047] like Figure 3-Figure 9 As shown, a filter assembly 4 is arranged in the feed bin 21; the filter assembly 4 includes a vibration table 46; the vibration table 46 is fixedly connected to the side wall of the feed bin 21; the four corners of the vibration table 46 are fixedly connected to vibration springs 461; one end of the vibration spring 461 away from the vibration table 46 is fixedly connected to a filter plate 462; the vertical auger 25 is arranged in the middle of the filter plate 462; the feed port 22 is arranged above the filter plate 462;

[0048] During operation, as anti-skid quartz sand used in high-speed trains, there are certain requirements for the particle size of the quartz sand. Quartz sand with smaller particle size cannot meet the anti-skid effect of the train during braking. Therefore, when the quartz sand enters the filter plate 462 in the feed bin 21 from the feed port 22, a part of the quartz sand will be filtered out by the filter plate 462, and the quartz sand with smaller particle size will be filtered to the bottom of the filter plate 462. The quartz sand remaining on the filter plate 462 is transported to the sand box through the vertical auger 25 and the horizontal auger 241.

[0049] like Figure 3-Figure 9 As shown, the side wall of the feed bin 21 is fixedly connected with a connecting plate 45; the vertical auger 25 is rotatably connected to the middle of the connecting plate 45; the vertical auger 25 passes through the filter plate 462 and is arranged with the feed bin 21; the vertical auger 25 is fixedly connected with a filter gear 44; the filter gear 44 is arranged below the filter plate 462; the side wall of the vertical auger 25 is rotatably connected with a connecting rod 41; the connecting rod 41 is provided with two groups; the end of the connecting rod 41 away from the vertical auger 25 is rotatably connected with A rotating disk 42; a striking column 43 is fixedly connected to the rotating disk 42; a telescopic slot 431 is provided in the striking column 43; a telescopic spring 432 is fixedly connected in the telescopic slot 431; a striking head 433 is fixedly connected to one end of the telescopic spring 432 away from the telescopic slot 431; a pulley 434 is rotatably connected to one end of the striking head 433 away from the telescopic spring 432; a connecting tooth 421 is fixedly connected to the side wall of the rotating disk 42; the connecting tooth 421 is meshedly connected to the filter gear 44;

[0050] During operation, the connecting rod 41 is rotated and sleeved on the vertical auger 25. When the vertical auger 25 rotates, the filter gear 44 is driven to rotate. When the filter gear 44 rotates, the connecting teeth 421 on the turntable 42 are driven to rotate, thereby driving the turntable 42 to rotate as a whole. When the turntable 42 rotates, the striking column 43 and the striking head 433 on the side wall of the turntable 42 will contact the bottom of the filter plate 462, and the filter plate 462 will be struck by the striking head 433 during rotation. During the striking process, the vibration spring 461 at the bottom of the filter plate 462 will be squeezed. The vibration spring 461 will rebound when subjected to the striking force, and the filter plate 462 will be driven to vibrate during the rebound process. The striking head 433 is moved to filter the quartz sand, and the vibration effect can prevent the quartz sand from being blocked on the filter plate 462, thereby affecting the overall filtering effect of the filter plate 462. When the striking head 433 contacts the bottom of the filter plate 462, the telescopic spring 432 inside the striking column 43 is also squeezed. The buffering of the telescopic spring 432 can prevent the striking head 433 from having a hard collision with the filter plate 462 and damaging the filter plate 462. A pulley 434 is provided at the end of the striking head 433. The sliding of the pulley 434 can reduce the friction between the striking head 433 and the filter plate 462, thereby protecting the filter plate 462 from being damaged by the striking head 433 to the greatest extent.

[0051] like Figure 1 and Figure 2 As shown, the bottom of the feeding bin 21 is slidably connected to the collecting bin 5; the side wall of the vertical conveying bin 23 is fixedly connected to the supporting column 29; the end of the supporting column 29 away from the vertical conveying bin 23 is fixedly connected to the horizontal conveying bin 24;

[0052] During operation, the filtered quartz sand can fall into the collecting bin 5 at the bottom of the feeding bin 21. After the sand adding work is completed, the quartz sand in the collecting bin 5 is taken out and can be used for other purposes to avoid waste. The support column 29 can connect and support the vertical conveying bin 23 and the horizontal conveying bin 24.

[0053] like Figure 3 As shown, the side wall of the storage bin 31 is fixedly connected with a support plate 33; the end of the support plate 33 away from the storage bin 31 is fixedly connected with an inclined plate 36; the end of the inclined plate 36 away from the support plate 33 is fixedly connected to the side wall of the storage bin 31 and is arranged below the feed port 22; the side wall of the storage bin 31 above the support plate 33 is rotatably connected with a rotating shaft 34; the rotating shaft 34 is provided with three groups; the rotating shaft 34 is fixedly connected with a stirring plate 35;

[0054] During operation, the quartz sand enters the storage bin 31 and is supported by the support plate 33. The quartz sand at the inclined plate 36 will slide through the inclined plate 36 to the feed port 22 and then enter the feed bin 21 for feeding. The quartz sand away from the inclined plate 36 is transferred by the rotation of the stirring plate 35. The setting of the stirring plate 35 can prevent the quartz sand from becoming lumpy and clogging the feed port 22.

[0055] like Figure 6 As shown, the top of the feeding bin 21 is fixedly connected to a top plate 211; the vertical feeding bin 23 is fixedly connected to the top plate 211; the end of the vertical feeding bin 23 away from the feeding bin 21 is fixedly connected to a partition 251; the vertical auger 25 is arranged below the partition 251;

[0056] During operation, the top plate 211 is used to support the vertical feeding bin 21 , and the partition plate 251 is used to block the quartz sand to prevent the quartz sand from reaching the driving gear 252 .

[0057] like Figure 6 As shown, the bottom side wall of the storage bin 31 is fixedly connected to a heating pipe 32; the outer side wall of the storage bin 31 is fixedly connected to a heating motor 37; the bottom of the connecting plate 45 is fixedly connected to a driving motor 28; the vertical auger 25 is driven to rotate by the driving motor 28;

[0058] During operation, the heating tube 32 is arranged to prevent the quartz sand from becoming damp and affecting the quality of the quartz sand. The vertical auger 25 is driven to rotate by the driving motor 28, thereby driving the horizontal auger 241 and the turntable 42 in the filter assembly 4 to rotate.

[0059] Working principle of the present invention: In the prior art, during the use of the high-pressure air pump type automatic sanding machine, the sand and gravel carried by the high-pressure airflow can easily cause serious air pollution, and the pump body, valves and other components used to transport the sand and gravel are seriously worn by the sand and gravel, resulting in the equipment being damaged after a certain period of use, and frequent maintenance or replacement of parts is required, which increases the cost of adding sand, and the quartz sand used in high-speed trains has certain requirements on the particle size of the quartz sand. The quartz sand with a smaller particle size cannot meet the anti-skid effect required by the train during braking, so the quartz sand needs to be filtered to avoid In order to prevent a large amount of unqualified quartz sand from appearing when adding sand, thereby affecting the braking of the train, in order to prevent such an incident from happening, first, the quartz sand is loaded into the storage bin 31, and then the quartz sand in the storage bin 31 will reach the feed bin 21 through the feed port 22. When the train needs to add sand, the mobile vehicle 1 is driven to the sand box of the train, and then the discharge pipe 243 is rotated, and the discharge pipe 243 is rotated to the sand inlet of the sand box, and then the vertical auger 25 in the feed bin 21 is driven to rotate. When rotating, the vertical auger 25 transports the quartz sand in the feed bin 21 to the top of the vertical conveying bin 23. After reaching the top, the quartz sand will slide from the transfer pipe 26 on the side wall of the vertical conveying bin 23 to the horizontal conveying bin 24. After reaching the horizontal conveying bin 24, the quartz sand is transported to the discharge box 242 by the horizontal auger 241, and then enters the train sand box through the discharge pipe 243. When the vertical auger 25 rotates, the first connecting shaft 254 can be driven to rotate, so that the first gear 255 and the transmission belt 256 can be used to drive the second gear 245 below to rotate. The second gear 245 is fixedly connected to the output end of the horizontal auger 241. When the vertical auger 25 rotates, the first connecting shaft 254 can be driven to rotate, so that the second gear 245 below can be driven to rotate. The gear 255 and the second gear 245 drive the horizontal auger 241 to rotate, realizing vertical and horizontal transportation, thereby transporting the quartz sand from the feed bin 21 to the discharge box 242. Through the setting of the first gear 255 and the second gear 245, the two groups of augers can be driven to rotate at the same time, and the rotation speed of the horizontal auger 241 can be adjusted according to the rotation speed of the vertical auger 25 to achieve the purpose of rapid sand addition, thereby improving the efficiency of sand addition, and through the setting of the vertical conveying bin 23 and the horizontal conveying bin 24, the quartz sand can be prevented from being exposed to the air and causing air pollution.

[0060] Among them, the filter component 4 can filter quartz sand, and the connecting rod 41 is rotatably sleeved on the vertical auger 25. When the vertical auger 25 rotates, it will drive the filter gear 44 to rotate. When the filter gear 44 rotates, it will drive the connecting teeth 421 on the turntable 42 to rotate, thereby driving the turntable 42 to rotate as a whole. When the turntable 42 rotates, the striking column 43 and the striking head 433 on the side wall of the turntable 42 will contact the bottom of the filter plate 462, and the filter plate 462 will be struck by the striking head 433 during rotation. During the striking process, the vibration spring 461 at the bottom of the filter plate 462 will be squeezed. The vibration spring 461 will rebound when it is hit, and drive the filter plate 462 to vibrate during the rebound process, thereby filtering the quartz sand. The vibration effect can prevent the quartz sand from being blocked on the filter plate 462 and affecting the overall filtering effect of the filter plate 462.

[0061] Furthermore, the filter plate 462 can be effectively protected by the components arranged in the striking column 43. When the striking head 433 contacts the bottom of the filter plate 462, the telescopic spring 432 inside the striking column 43 will also be squeezed. The buffering of the telescopic spring 432 can avoid a hard collision between the striking head 433 and the filter plate 462, thereby avoiding damage to the filter plate 462. A pulley 434 is arranged at the end of the striking head 433. The sliding of the pulley 434 can reduce the friction between the striking head 433 and the filter plate 462, thereby protecting the filter plate 462 from damage by the striking head 433 to the greatest extent.
