[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] The tiny particles in the exhaust gas generated by the integrated device in the grinding car and the dust that enters the car through the gaps are easy to accumulate on the inner wall of the car. Therefore, it is necessary to use a walking mechanism to support the cleaning and blowing mechanism to clean the inner wall of the car. The currently designed walking mechanism adopts a rail car that is hoisted and installed on the track. The cleaning and blowing mechanism is installed at the bottom of the rail car. However, the cleaning and blowing mechanism cannot clean the dust on the track. The dust on the track still needs to be cleaned manually. The height of the track is high, and the cleaning is difficult and inconvenient.
[0004] Therefore, it is necessary to provide a running mechanism inside the carriage of a rail grinding vehicle to solve the above-mentioned technical problems. Utility Model Content

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.
[0028] Embodiment 1:
[0029] like Figure 1-6As shown, the walking mechanism inside the carriage of the rail grinding vehicle provided by the utility model includes: a rail 1 and a rail car 2 hoisted and installed under the rail 1, a blowing mechanism 3 installed under the rail car 2, and the blowing mechanism 3 can spray high-speed airflow to the inner wall of the carriage, so as to blow away the dust attached to the inner wall. The blowing mechanism 3 can adopt a manipulator or other structural design, because it is irrelevant to the direction that needs to be improved in this application, it is no longer described in detail. A clamping part 4 is provided on the rail 1, and a clamping wheel 5 is installed on the rail car 2. Four clamping wheels 5 are respectively clamped on the clamping part 4 from both sides, so that the rail car 2 moves along the rail 1. It is worth mentioning that the top of the rail 1 is tightly connected to the roof (not easy to accumulate dust), and the top of the clamping part 4 is the place where the most dust falls on the rail 1. Since the clamping wheel 5 is in contact with this place, it is also the position that most affects the rotation of the clamping wheel 5. When the clamping wheel 5 is in contact with this place, it is also the position that most affects the rotation of the clamping wheel 5. Too much dust accumulates in the area, especially iron filings contained in the dust. Small iron filings are easily oxidized and rusted, which can easily accelerate the corrosion rate of the track 1, making the contact area between the track 1 and the clamping wheel 5 no longer flat, thereby reducing the stability of the rail car 2 when moving and increasing the noise. In order to solve this problem, two cleaning plates 6 are installed on the rail car 2. The cleaning plate 6 is hollow, and its interior is connected to the air pump on the rail car 2 through a pipeline. A plurality of air outlet pipes 7 are installed on the cleaning plate 6 in the upper, lower and inner directions. The diameter of the air outlet pipe 7 is small, so that the high-pressure gas in the cleaning plate 6 is discharged through the air outlet pipe 7 at a faster flow rate. The high-speed airflow blows to the position of the clamping part 4, which can blow away the dust at the position of the clamping part 4, thereby keeping the contact area between the clamping wheel 5 and the clamping part 4 clean. As the track 2 continues to move along the track 1, the track 1 can be fully dusted.
[0030] By setting up the track 1 and the track car 2, and installing two hollow cleaning plates 6 on the track car 2, high-pressure gas is injected into the cleaning plate 6, so that the high-pressure gas 6 is discharged through the outlet pipe 7 with a high-speed airflow, and the high-speed airflow is used to blow away the dust at the contact part between the track 1 and the clamping wheel 5 and the nearby part, so that the track 1 can be conveniently dusted.
[0031] Embodiment 2:
[0032] like Figure 2-4 As shown, the track 1 is straight, L-shaped, U-shaped or circular. In order to adapt to the use environment of polishing the interior of the carriage, the straight, L-shaped, U-shaped or circular track 1 can be used individually or in combination to avoid interference with the equipment in the carriage, so that the walking mechanism can be adapted to different use environments.
[0033] By setting the track 1 to be straight, L-shaped, U-shaped or ring-shaped, it is possible to conveniently select different tracks 1 for use according to the use environment of the interior of the carriage.
[0034] Embodiment 3:
[0035] like Figure 5-6 As shown, two U-shaped brackets 8 are installed on the rail vehicle 2, and the clamping wheel 5 is connected to the brackets 8. When in use, the rotating shaft of the clamping wheel 5 is fixedly connected to the brackets 8, thereby supporting and fixing the clamping wheel 5.
[0036] By installing two U-shaped brackets 8 on the rail vehicle 2, the clamping wheel 5 can be supported and fixed conveniently.
[0037] Embodiment 4:
[0038] like Figure 5-6 As shown, a rotating shaft 9 is installed between the bracket 8 and the rail vehicle 2. The bracket 8 can be rotated around the rotating shaft 9, so that the rail vehicle 2 can turn conveniently when encountering a turning point of the track 1.
[0039] By installing the rotating shaft 9 between the bracket 8 and the rail vehicle 2 , the bracket 8 can be rotated, which facilitates the rail vehicle 2 to smoothly pass through the turning point of the track 1 .
[0040] Embodiment 5:
[0041] like Figure 5-6 As shown, a fixed block 10 is installed on the rail car 2, and a return spring 11 is installed between the fixed block 10 and the bracket 8, wherein the direction of the arrow refers to the rotation direction of the two brackets 8, and when the bracket 8 passes through the turning point of the track 1, the bracket 8 will deflect, so that the return spring 11 is stretched, and after passing the turning point, the return spring 11 contracts to help the bracket 8 to rotate in the opposite direction and reset, and under the pulling force of the return spring 11, the bracket 8 is not easy to deflect, and thus more stable.
[0042] By installing the return spring 11 between the rail vehicle 2 and the bracket 8 , the bracket 8 can be reset and the stability of the bracket 8 can be improved.
[0043] Embodiment 6:
[0044] like Figure 1 and Figure 5 As shown, a rack 13 is installed at the bottom of the track 1 toward the inner side (towards the center of the car), a drive motor 14 is installed on the rail car 2, and a drive gear 15 is installed at the top of the drive motor 14. The drive gear 15 is meshed with the rack 13. When in use, the drive motor 14 is started to rotate the drive gear 15, and the rotation of the drive gear 15 causes the rail car 2 to move. The rack 13 is installed toward the middle of the car, so that grease can be easily applied to the rack 13 and the drive gear 15.
[0045] By providing the rack 13 , the driving motor 14 and the driving gear 15 , the rail vehicle 2 can be conveniently driven to move along the track 1 .
[0046] Working principle: When in use, high-pressure gas is injected into the cleaning plate 6 through an air pump. The high-pressure gas in the cleaning plate 6 has a fast flow rate when discharged through the outlet pipe 7. The high-speed airflow blows toward the position of the clamping part 4, which can blow away the dust at the position of the clamping part 4, thereby keeping the contact part between the clamping wheel 5 and the clamping part 4 clean, and as the track 2 continues to move along the track 1, the track 1 can be fully dusted, effectively removing the dust at the contact position between the clamping wheel 5 and the track 1.
