Description

Technical Field

[0001] The utility model relates to the technical field of antifreeze liquid spraying, in particular to an antifreeze liquid spraying device for a railway antifreeze station. Background Art

[0002] When loading for railway transportation, the problem of freezing of the vehicle is generally solved by spraying antifreeze on the inner wall of the vehicle, the bottom of the vehicle and bulk cargo such as water-containing coal. However, when the existing antifreeze is sprayed or applied on the wall of the vehicle for transporting coal, the antifreeze will quickly flow to the bottom of the vehicle along the wall of the vehicle, causing the antifreeze layer on the wall of the vehicle to become thinner, thereby reducing the effectiveness of the antifreeze, and further resulting in the antifreeze effect of coal transportation at extremely low temperatures being very unsatisfactory.

[0003] The utility model patent with announcement number CN220004592U discloses an automatic antifreeze spraying system for coal cars, which drives the carriage nozzle structure to move into the carriage through the lifting drive to prevent the antifreeze from splashing out. This system lacks a cleaning structure after the antifreeze is sprayed. Direct cleaning with solution requires additional equipment to receive the sprayed cleaning liquid, which is relatively cumbersome to operate. Utility Model Content

[0006] Compared with the prior art, the beneficial effect of the utility model is that in order to prevent the carriage spraying structure from hindering the normal progress of the train, the utility model is provided with a rotatable and liftable carriage nozzle.

DETAILED DESCRIPTION

[0018] In order to fully understand the purpose, features and effects of the present invention, the present invention is described in detail through the following specific implementation methods, but the present invention is not limited thereto.

[0019] like Figure 1 As shown, the utility model provides a spraying device for antifreeze liquid in a railway antifreeze station, which includes a carriage spraying structure and a coal spraying structure. The antifreeze liquid sources of the carriage spraying structure and the coal spraying structure are both antifreeze liquid storage units.

[0020] like Figure 2 As shown, the carriage spraying structure includes a lifting rod body 2, a hydraulic rotary machine 1, a liquid inlet pipe 4, a carriage nozzle 5, a liquid return pipe 16 and a liquid return baffle 13. The hydraulic rotary machine 1 is fixed on the base platform outside the railway track. The output shaft of the hydraulic rotary machine 1 is vertically arranged upward, and the output shaft is connected to the lower end of the lifting rod body 2 through a coupling. The lifting rod body 2 can be a hydraulic telescopic cylinder, a pneumatic telescopic cylinder, etc. The upper end of the lifting rod body 2 is connected to a horizontally arranged spraying swing arm 3, and the liquid inlet pipe 4 is installed on the spraying swing arm 3. The liquid inlet pipe 4 and the spraying swing arm 3 are arranged through the length. The outer end part of the liquid inlet pipe 4 is equipped with a plurality of carriage nozzles 5, and the directions of the carriage nozzles 5 are different, ensuring that the spraying range of all carriage nozzles 5 covers all inner walls of the carriage to be sprayed.

[0021] like Figure 3As shown, a vertical plate is fixed at the outer end of the spraying swing arm 3, and a servo motor 12 is installed on the vertical plate. The liquid return baffle 13 is an open cylindrical tank structure, and the outer walls of the two ends of the tank are respectively connected with rotating shafts, one of which is connected to the output shaft of the servo motor 12 through a coupling, or a driven gear is installed on the rotating shaft, and a driving gear is installed on the output shaft of the servo motor 12. The driving gear and the driven gear mesh to drive the liquid return baffle to rotate. The other rotating shaft is rotatably connected to the outer end surface of the spraying swing arm 3. The bottom plate of the liquid return baffle 13 connected to the servo motor 12 is provided with a liquid return hole 14, and a liquid return joint is welded on the outer side of the liquid return hole 14. A liquid return hose 15 is connected to the liquid return joint, and the liquid return hose 15 is connected to the liquid return pipe 16, and the liquid return pipe 16 is connected to the antifreeze storage unit. The liquid return hose 15 can be flexibly deformed with the rotation of the liquid return baffle 13 to meet the rotation requirements of the liquid return baffle. When the liquid return baffle 13 rotates to above the carriage nozzle 5, the liquid return baffle 13 will not hinder the carriage nozzle 5 from spraying antifreeze downward; when cleaning is required, the liquid return baffle 13 is driven by the servo motor 12 to rotate to the position below the carriage nozzle 5, wrap it up, and collect the cleaning liquid.

[0022] The liquid return pipe and liquid inlet pipe ports at the end of the spray swing arm 3 are respectively connected to the vertical liquid return pipe and liquid inlet pipe through flexible hoses to meet the deformation requirements of the liquid pipeline when the spray swing arm 3 rotates and the lifting rod body rises and falls.

[0023] like Figure 1 and Figure 4 As shown, a coal spraying structure is arranged in front of the carriage spraying structure, that is, the carriage reaches the carriage spraying structure first, and then reaches the coal spraying structure. The coal spraying structure includes a silo hopper 6, a silo chute 7, a conveying pipe 8 and a coal nozzle 10. The silo funnel 6 is located at a higher position and is supported by a platform. The lower section of the silo funnel 6 is an arc structure that exceeds 1 / 2 of a circle, and a discharge port is provided at the lower end of the arc structure. The lower part of the silo funnel 6 is hinged to the silo chute 7 through a rotating shaft, and a driving motor is connected to the outer end of one side of the rotating shaft to provide rotational power for the silo chute 7. The size of the discharge port is less than or equal to the inner cross-sectional size of the silo chute 7. An arc baffle 71 is fixed to the upper outer side wall of the silo chute 7, and the curvature of the arc baffle 71 fits the lower part of the silo funnel 6. When the silo chute 7 is in a horizontal state, the arc-shaped baffle 71 covers the outside of the discharge port, thereby closing the silo funnel 6; when the silo chute 7 is in a vertical state, the discharge port overlaps with the inner port of the silo chute 7, and the material is discharged from the silo funnel 6 along the silo chute 7. At this time, the arc-shaped baffle 71 slides along the arc at the lower end of the silo funnel 6 to the side of the discharge port without interfering with other structures.

[0024] A discharge valve is installed at the lower port of the silo chute 7. A straight pipe 9 is fixed to the outer side wall of the lower end of the silo chute 7. Several coal nozzles 10 are evenly distributed on the straight pipe 9. The angle of the coal nozzles 10 is determined according to the actual conditions such as the size of the carriage. The straight pipe 9 is connected to the lower end of the delivery pipe 8. The delivery pipe 8 is fixed on the outer side wall of the silo chute 7. The upper end of the delivery pipe 8 is connected to a hose 11. The hose 11 is connected to the antifreeze delivery hard pipe. When the silo chute 7 rotates, the hose 11 plays a role in deformation transition. The hose 11 and the hard pipe are both connecting pipes, and a solenoid valve is installed on the connecting hard pipe. The connecting hard pipe is connected to the antifreeze storage unit.

[0025] Working process:

[0026] In the initial state without train carriages, the silo chute 7 is placed horizontally, the discharge valve is closed, and the spraying arm 3 is located outside the track. After the carriage to be loaded with coal reaches the specified position, the hydraulic rotary machine 1 is started to rotate the spraying arm 3 180° and turn it to the top of the carriage. The lifting rod body 2 is started, and the spraying arm 3 is lowered to a height of about 10 cm from the top of the carriage. The output valve of the antifreeze storage unit is opened to transport liquid to the liquid inlet pipe 4. At the same time, the carriage nozzle 5 is opened to start the spraying operation of the inner side wall and the inner bottom surface of the carriage. After the antifreeze spraying in the carriage is completed, the carriage nozzle 5 is closed, and this carriage moves forward to reach the coal loading position. The next carriage reaches the carriage spraying structure position, and the carriage nozzle 5 is opened again.

[0027] The silo chute 7 rotates 90° and becomes vertical. A certain height is reserved between the lower end of the silo chute 7 and the upper end of the carriage. The discharge valve, the solenoid valve on the delivery pipe 8 and the coal nozzle 10 are opened to start loading clean coal into the carriage. At the same time, antifreeze is sprayed on the clean coal discharged from the lower end of the silo chute 7. The coal and antifreeze are mixed together. After the coal loading is completed, the coal nozzle 10 and the discharge valve are closed. When the next carriage reaches the coal loading position, the feed valve and the coal nozzle 10 are reopened.

[0028] During the entire process of loading this train, the spraying arm 3 and the silo chute 7 remain in working condition, with only the valves opened and closed. After the train is loaded, all valves in the coal spraying structure are closed, and the silo chute 7 is turned to a horizontal position. The carriage spraying structure is cleaned, the servo motor 12 is started, the liquid return baffle 13 is turned to the carriage nozzle 5 facing downward, and clean water is transported to the liquid inlet pipe 4. The liquid sprayed from the carriage nozzle 5 falls into the liquid return baffle 13 and returns to the antifreeze storage unit through the liquid return pipe 16, effectively cleaning the carriage spraying structure. After the cleaning is completed, all valves in the carriage spraying structure are closed, the lifting rod body 2 drives the spraying arm 3 to rise, and the hydraulic rotary machine 1 resets the spraying arm 3 to end the antifreeze spraying operation.

[0029] Finally, it should be noted that the above-listed examples are only preferred embodiments of the present invention. Of course, those skilled in the art can make changes and modifications to the present invention. If these modifications and modifications fall within the scope of the claims of the present invention and their equivalent technologies, they should be considered to be within the scope of protection of the present invention.
