Description

Technical Field

[0001] The utility model relates to the technical field of railway component products, in particular to an operation monitoring device for the air source system of a railway locomotive. Background Technique

[0002] Compressors and dryers are usually equipped on locomotives. The compressor is equipped with a working state detection system. When the internal temperature is too high or the pressure is too large, the compressor will be automatically prohibited from being put into use. However, the dryer is prone to failures such as blockage. Especially in an environment with high humidity and low temperature, if the blowdown valve of the dryer gets stuck, the waste water cannot be discharged in time, and it is easy to freeze at low temperature, blocking the drying tower, resulting in poor air passage inside the dryer, thereby affecting the normal transmission of compressed air and causing abnormal braking of the locomotive.

[0003] According to a disclosed railway locomotive air dryer (Publication No.: CN213050052U), the above application includes a dryer housing, a ventilation device, a filtering device, and a membrane dryer. Both ends of the fixed rod are respectively connected to a fixed block and the inner surface of the ventilation device. The outer surface of the ventilation device is welded to the dryer housing. One end of the rotating shaft is connected to the fixed block. One side of the air distribution plate is connected to the filtering device, and the other side is provided with a number of through holes, and the through holes are connected to a number of membrane dryers.

[0004] However, due to the complex operating environment of the locomotive, especially the dust in the railway environment is easy to block the dryer, resulting in the inability to discharge condensed water normally, which will cause poor air passage inside the dryer, thereby affecting the normal transmission of compressed air. In view of this, we have proposed an operation monitoring device for the air source system of a railway locomotive. Content of the Utility Model

[0005] The purpose of the utility model is to provide an operation monitoring device for the air source system of a railway locomotive to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An operation monitoring device for the air source system of a railway locomotive, including a housing, a fan is fixedly connected inside the housing, an installation shell is fixedly connected to the right side of the housing, a membrane dryer is fixedly connected to the right side of the installation shell, and a cleaning component is arranged on the inner wall of the installation shell. The cleaning component includes:

[0007] A filter screen, a cross plate is fixedly connected to the inner wall of the installation shell, and a filter screen is fixedly connected to the bottom end face of the cross plate;

[0008] A scraper, a motor is fixedly connected to the top end face of the installation shell, the output end of the motor is fixedly connected to a first reciprocating lead screw, and a scraper is threadedly connected to the side wall of the first reciprocating lead screw;

[0009] The top end surface of the horizontal plate is sleeved with a reciprocating screw rod 2, the side wall of the reciprocating screw rod 2 is threadedly connected with a limiting sleeve, the limiting sleeve is sleeved with the brush, and the reciprocating screw rod 2 is transmission-connected with the reciprocating screw rod 1 through a sleeved belt;

[0010] The corrugated plate is fixedly connected to the bottom end surface of the horizontal plate, the brush is fixedly connected to the spring, one end of the spring away from the brush is fixedly connected to the inner wall of the limiting sleeve, and the side wall of the brush is fixedly connected to the cross bar.

[0011] Preferably, a temporary storage plate is hinged on the side wall of the limiting sleeve, and a limiting rod is fixedly connected to the inner wall of the mounting shell.

[0012] Preferably, a shielding net is fixedly connected to the left side of the shell, and the shielding net blocks large branches and the like to prevent them from being entangled in the fan.

[0013] Preferably, a maintenance door is hinged on the side wall of the installation shell, and a guide arc plate is fixedly connected to the inner wall of the installation shell.

[0014] Preferably, the bottom end surface of the horizontal plate is fixedly connected with a vertical rod, and the vertical rods are arranged in two groups, wherein the vertical rods in one group are movably connected to the scraper, and the vertical rods in the other group are movably connected to the limit sleeve.

[0015] Preferably, the cross bar is movably connected to the wave plate, and the cross bar moves along the wave plate to generate lateral vibration.

[0016] Compared with the prior art, the utility model provides a railway locomotive air source system operation monitoring device, which has the following beneficial effects:

[0017] 1. The railway locomotive air source system operation monitoring device has a scraper, a limit sleeve, a brush, a spring and a wave plate. The scraper scrapes off the dust on the side of the filter close to the fan, so that the dust falls into the top of the installation shell, improves the efficiency of air drying, and thus ensures the normal transmission of pressurized air. The limit sleeve and the brush move longitudinally to clean the gaps in the filter. At the same time, when the brush moves longitudinally, the spring pushes the brush to always contact the filter. At this time, the crossbar always moves along the wave plate, so that the brush generates lateral vibration while moving longitudinally, further promoting the shaking off of dust on the filter and improving the cleaning effect of the filter.

[0018] 2. The railway locomotive air source system operation monitoring device, through the provision of a temporary storage plate and a limit rod, allows the dust passing through the filter to fall between the temporary storage plate and the filter to prevent the dust from scattering. When the temporary storage plate moves downward, the limit rod is inserted into the gap between the temporary storage plate and the filter, allowing the dust to fall into the inner bottom surface of the installation shell, thereby reducing the probability of dust entering the membrane dryer and improving the working efficiency of the membrane dryer.

[0029] like Figures 1 - 9 As shown, the utility model provides a technical solution: a railway locomotive air source system operation monitoring device, including a shell 1, a fan 2 is fixedly connected to the inside of the shell 1, a shielding net 3 is fixedly connected to the left side of the shell 1, the shielding net 3 blocks large branches and the like to prevent them from being entangled by the fan 2, a mounting shell 4 is fixedly connected to the right side of the shell 1, a membrane dryer 5 is fixedly connected to the right side of the mounting shell 4, and a cleaning component is arranged on the inner wall of the mounting shell 4, and the cleaning component includes a horizontal plate 7, a filter screen 8, a motor 9, a reciprocating screw rod 10, a scraper 11, a reciprocating screw rod 2 12, a limit sleeve 13, a brush 14, a spring 15, a wave plate 16, a vertical rod 17, a guide arc plate 18, a temporary storage plate 19, a limit rod 20, a belt 21, and a horizontal rod 22.

[0030] In an embodiment of the present utility model, a horizontal plate 7 is fixedly connected to the inner wall of the mounting shell 4. A filter screen 8 is fixedly connected to the bottom end face of the horizontal plate 7. A motor 9 is fixedly connected to the top end face of the mounting shell 4. The output end of the motor 9 is fixedly connected to a first reciprocating lead screw 10. A scraper 11 is threadedly connected to the side wall of the first reciprocating lead screw 10. A second reciprocating lead screw 12 is sleeved on the top end face of the horizontal plate 7. A limiting sleeve 13 is threadedly connected to the side wall of the second reciprocating lead screw 12. The limiting sleeve 13 is sleeved with a brush 14. The second reciprocating lead screw 12 is drivingly connected to the first reciprocating lead screw 10 through a sleeved belt 21. A vertical rod 17 is fixedly connected to the bottom end face of the horizontal plate 7. The number of the vertical rods 17 is set to two groups. One group of the vertical rods 17 is movably connected to the scraper 11, and the other group of the vertical rods 17 is movably connected to the limiting sleeve 13. A corrugated plate 16 is fixedly connected to the bottom end face of the horizontal plate 7. The brush 14 is fixedly connected to a spring 15. One end of the spring 15 away from the brush 14 is fixedly connected to the inner wall of the limiting sleeve 13. A cross bar 22 is fixedly connected to the side wall of the brush 14. The cross bar 22 is movably connected to the corrugated plate 16. The cross bar 22 moves along the corrugated plate 16, thereby generating a lateral vibration. A temporary storage plate 19 is hinged to the side wall of the limiting sleeve 13. A limiting rod 20 is fixedly connected to the inner wall of the mounting shell 4. A maintenance door 6 is hinged to the side wall of the mounting shell 4. The dust on the inner bottom surface of the mounting shell 4 is swept out through the maintenance door 6. A guiding arc plate 18 is fixedly connected to the inner wall of the mounting shell 4, so that the wind can directly blow towards the filter screen 8 and will not blow towards the bottom of the mounting shell 4.

[0031] The air blower 2 sucks air into the mounting shell 4. The filter screen 8 intercepts the dust. The motor 9 is started to drive the first reciprocating lead screw 10 to rotate, thereby enabling the scraper 11 to move longitudinally. The scraper 11 scrapes off the dust on the side of the filter screen 8 close to the air blower 2, so that the dust falls into the top of the mounting shell 4, improving the efficiency of air drying and thus ensuring the normal transmission of pressurized air. The rotation of the first reciprocating lead screw 10 drives the second reciprocating lead screw 12 to rotate through the transmission of the belt 21, thereby enabling the limiting sleeve 13 and the brush 14 to move longitudinally, cleaning the gaps of the filter screen 8. At the same time, when the brush 14 moves longitudinally, the spring 15 pushes the brush 14 to always contact the filter screen 8. At this time, the cross bar 22 always moves along the corrugated plate 16, so that the brush 14 generates a lateral vibration while moving longitudinally, further promoting the shaking off of the dust on the filter screen 8 and improving the cleaning effect of the filter screen 8.

[0032] In addition, a temporary storage plate 19 is hinged to the side wall of the limiting sleeve 13. A limiting rod 20 is fixedly connected to the inner wall of the mounting shell 4. One side of the temporary storage plate 19 away from the limiting sleeve 13 always contacts the filter screen 8. The dust passing through the filter screen 8 falls between the temporary storage plate 19 and the filter screen 8 to prevent the dust from scattering. When the temporary storage plate 19 moves downward, the limiting rod 20 is inserted into the gap between the temporary storage plate 19 and the filter screen 8, so that the dust can fall into the inner bottom surface of the mounting shell 4, reducing the probability of dust entering the membrane dryer 5 and improving the working efficiency of the membrane dryer 5.

[0033] In the present utility model, during use, the filter screen 8 intercepts dust. The scraper 11 moves longitudinally, and the scraper 11 scrapes off the dust on the side of the filter screen 8 close to the blower 2. The brush 14 moves longitudinally to clean the gaps of the filter screen 8, and at the same time, the transverse vibration promotes the shaking off of the dust on the filter screen 8. Further, the dust falls between the temporary storage plate 19 and the filter screen 8, and the limiting rod 20 is inserted into the gap between the temporary storage plate 19 and the filter screen 8, so that the dust can fall onto the inner bottom surface of the installation shell 4.

[0034] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements made without departing from the spirit of the present utility model are within the protection scope of the present utility model.
