[0002] Rails are an important part of railways, and they generally need to be regularly polished to maintain the quality of the railway. The main purpose of rail grinding is to eliminate the corrugated wear of the rails, control the contact fatigue of the rails, and prevent the flaking and cracking caused by contact fatigue, which can greatly extend the service life of the rails.

[0003] At present, rail grinding is carried out by rail grinding vehicles, and debris and dust are generated after the rail grinding is completed. Although the dust collection equipment installed in the car can collect the dust and debris under the car, the gas discharged by the dust collection equipment will still have extremely fine dust discharged with the exhaust gas. The dust will stick to the inner wall of the rail grinding car and accumulate for a long time. In addition, the dust that enters the car through the gaps in the car can easily cause pollution and corrosion to the inner wall and the pipes and equipment on the inner wall of the car. Therefore, it needs to be cleaned manually, which is time-consuming, labor-intensive and inconvenient.

DETAILED DESCRIPTION

[0027] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments. Embodiment 1:

[0028] like Figure 1-6As shown, the cleaning and blowing mechanism inside the carriage of the rail grinding car provided by the utility model comprises: a soot blowing assembly 2 and an air pump 8 installed at the bottom of the rail car 1, one or two soot blowing assemblies 2 are installed at the bottom of one rail car 1, the soot blowing assembly 2 comprises an adjusting seat 3, the adjusting seat 3 is fixedly installed at the bottom of the rail car 1, a movable frame 4 is installed on the adjusting seat 3, the position of the movable frame 4 can be adjusted manually or electrically, a lifting frame 5 is installed on the movable frame 4, and an adjusting component is provided on the movable frame 4, and the height of the lifting frame 5 from the ground can be controlled by the adjusting component, and the adjusting component can be manual or electric, and its specific structure is not repeated here, an air supply pipe 6 is installed on the lifting frame 5, the air supply pipe 6 is connected to the air pump 8, and a plurality of nozzles 7 are evenly installed on the air supply pipe 6, and a plurality of air outlets 18 are opened on the nozzle 7, and the air outlet 18 can be arranged horizontally, obliquely, or in a fan shape. In this embodiment, the air outlet 18 is aligned with the inner wall of the carriage and slightly downward, and the air outlet 18 is adjusted by adjusting the seat 3. The distance between the air outlet 18 and the inner wall of the carriage can be adjusted to avoid interference with the equipment and pipelines in the polishing carriage. When there are two sootblowing assemblies 2, the two air supply pipes 6 should be arranged in parallel, and the nozzles 7 on the two air supply pipes 6 should be staggered up and down to reduce the existence of cleaning blind spots. This embodiment takes one sootblowing assembly 2 as an example for explanation. When in use, the rail car 1 runs around the inner wall of the carriage along the track. At the same time, the air pump 8 passes compressed air into the air supply pipe 6, and the high-pressure air in the air supply pipe 6 is discharged from the air outlet 18 and blown to the inner wall of the carriage, blowing off the dust attached to the inner wall and the equipment installed on the inner wall (such as lighting, etc.) and the pipeline. Since the air outlet 18 is installed obliquely downward, the blown dust falls to the bottom of the carriage after falling, and the sootblowing assembly 2 moves with the rail car 1, and can clean all around the carriage 1. Compared with manual cleaning operations, the cleaning and blowing mechanism provided in the present application can complete the cleaning operation of the inner wall of the carriage more conveniently and labor-savingly. Compared with using a robot or a manipulator, the device has lower cost and is suitable for popularization and use.

[0029] By setting up a rail car 1, a sootblowing assembly 2 and an air pump 8, the air pump 8 is used to supply air, and the generated high-pressure gas is supplied to a plurality of nozzles 7 arranged in a straight line through an air supply pipe 6. The high-pressure gas is obliquely ejected from the air outlet 18 toward the inner wall of the car. As the track 1 moves, the inner wall of the grinding car car can be cleaned conveniently and labor-savingly. Embodiment 2:

[0030] like Figure 4-5As shown, a screw rod 9 is installed on the adjustment seat 3, and the screw rod 9 can be driven by a motor. In this embodiment, the screw rod 9 is manually driven, and a knob 11 is installed at one end of the screw rod 9, and the screw rod 9 can be conveniently rotated by the knob 11. A threaded hole 10 is provided on the mobile frame 4, and the screw rod 9 is screwed into the threaded hole 10, so that the screw rod 9 is threadedly connected with the mobile frame 4. When in use, the knob 11 is turned to rotate the screw rod 9, and the rotation of the screw rod 9 drives the mobile frame 4 to move. It is worth noting that if the knob 11 is replaced by a motor, it can be more convenient and labor-saving, but correspondingly, the cost will also increase.

[0031] By providing the screw 9, the threaded hole 10 and the knob 11, the movable frame 4 can be conveniently connected to the adjustment seat 3, and the position of the movable frame 4 can be adjusted, thereby adjusting the distance between the nozzle 7 and the inner wall of the carriage. Embodiment 3:

[0032] like Figure 4 As shown, in order to prevent the knob 11 from moving, a plurality of limit holes 12 are opened on the knob 11, and a limit pin 13 is installed on the knob 11. The limit pin 13 is inserted into the lowest limit hole 12. The limit pin 13 abuts against the bottom of the adjustment seat 3, thereby preventing the knob 11 from rotating and playing a limiting role.

[0033] By opening a plurality of limiting holes 12 on the knob 11 and installing the limiting pins 13, the knob 11 can be conveniently limited to prevent it from rotating. Embodiment 4:

[0034] like Figure 5-6 As shown, in this embodiment, the adjustment component includes two rectangular holes 14 opened on the mobile frame 4, and two bolts 16 are installed on the lifting frame 5. The bolts 16 are inserted into the rectangular holes 14, and then nuts are installed on the bolts 16, and the position of the bolts 16 in the rectangular holes 14 is adjusted, so as to adjust the height of the lifting frame 5 from the ground, and then adjust the height of the air supply pipe 6 and the nozzle 7 from the ground to avoid interference with the equipment at the bottom of the car. Compared with the electric lifting method, the structural design of this embodiment is lower in cost, and once the structural design inside the car is fixed, it will basically not be greatly changed, and it is more appropriate to use manual adjustment.

[0035] By opening a rectangular hole 14 on the movable frame 4 and connecting the movable frame 4 to the lifting frame 5 by bolts 16 , the height of the lifting frame 5 , the air supply pipe 6 and the nozzle 7 above the ground can be adjusted. Embodiment 5:

[0036] like Figure 6As shown, a slot 15 is provided on the lifting frame 5, and a bolt 16 is installed in the slot 15. When in use, the bolt 16 is inserted into the rectangular hole 14 and locked with a nut. The two sides of the slot 15 are naturally stuck on the two sides of the mobile frame 4, thereby making the connection between the mobile frame 4 and the lifting frame 5 more stable.

[0037] By providing the card slot 15 on the lifting frame 5 , the connection between the moving frame 4 and the lifting frame 5 can be made more stable. Embodiment 6:

[0038] like Figure 6 As shown, a mounting hole 17 is opened on the lifting frame 5, and the mounting hole 17 is larger than the diameter of the air supply pipe 6, and a rubber ring is installed in the mounting hole 17. During installation, the air supply pipe 6 is inserted into the mounting hole 17, and the rubber ring is squeezed to stabilize the position of the air supply pipe 6. At the same time, the reaction force generated when the nozzle 7 sprays air acts on the rubber ring, which can reduce vibration. In addition, the air supply pipe 5 can also be rotated so that the nozzle 7 faces the side and front, so that the blown dust falls in front of the moving path.

[0039] By opening a mounting hole 17 on the lifting frame 5 and installing a rubber ring in the mounting hole 17 , the installation of the air supply pipe 5 and the adjustment of the direction of the nozzle 7 can be facilitated.

[0040] Working principle: When in use, the rail car 1 runs along the track around the inner wall of the carriage. At the same time, the air pump 8 passes compressed air into the air supply pipe 6. The high-pressure air in the air supply pipe 6 is discharged from the air outlet 18 and blown to the inner wall of the carriage, blowing off the dust attached to the inner wall and the equipment and pipelines installed on the inner wall. Since the air outlet 18 is installed obliquely downward, the blown dust falls to the bottom of the carriage after falling, and the soot blowing assembly 2 moves with the rail car 1, and can clean all around the carriage 1. Compared with manual cleaning operations, the cleaning and blowing mechanism provided by this application can complete the cleaning of the inner wall of the carriage more conveniently and labor-savingly. Compared with using robots or manipulators, the cost of this device is lower and suitable for promotion and use.
