[0033] Specifically, the track ballast cleaning device is provided with a mounting seat 10, an adjustment frame 20, a ballast roller brush 30 and an adjustment module 40. The cleaning device can be fixedly connected to the rail vehicle through the mounting seat 10, and then the cleaning device is driven to move by the movement of the rail vehicle along the track. The adjustment frame 20 is hinged to the mounting seat 10 and can rotate relative to the mounting seat 10. The ballast roller brush 30 is rotatably connected to the adjustment frame 20. The driving device of the rail vehicle is connected to the ballast roller brush 30 by , and drives the ballast roller brush 30 to rotate, so that the ballast roller brush 30 can scrape the track ballast to clean the track ballast. One end of the adjustment module 40 is hinged to the mounting seat 10, and the other end is hinged to the adjustment frame 20. The adjustment frame 20 can be driven to rotate, thereby driving the ballast roller brush 30 to move in the height direction, thereby adjusting the height of the ballast roller brush 30, so that the track ballast cleaning device can adapt to the ballast cleaning operations of various types of tracks.

[0034] In this embodiment, the rail vehicle equipped with the cleaning device can be any rail vehicle such as a trolley, a rail trolley, etc., which can be equipped with the cleaning device. The cleaning device is usually installed at the front end of the rail vehicle, and the ballast removal roller brush 30 is driven by a driving device to remove the ballast backwards. The driving device is a motor installed on the rail vehicle.

[0035] In one embodiment, Figures 1-2 As shown, the mounting seat 10 includes two parallel fixed frames 11, and the ballast roller brush 30 is located between the two fixed frames 11. Specifically, the ballast roller brush 30 is arranged between the two fixed frames 11, so that the stability of the ballast roller brush 30 during rotation can be ensured. At the same time, when installing the mounting seat 10, it is only necessary to fix the fixed frame 11 on the rail car horizontally and facing forward, so that the fixed frame 11 can be kept parallel to the rail, thereby ensuring that the ballast roller brush 30 is always kept between the two rails of the rail.

Specifically, by setting the adjustment frame 20 as two connecting arms 21, a rotation space can be provided for the ballast roller brush 30 to rotate while providing a rotatable connection for the ballast roller brush 30, and the weight of the adjustment frame 20 can be reduced, so as to facilitate the driving of the adjustment module 40.

[0037] In one embodiment, Figures 1-2As shown, the ballast removal roller brush 30 includes a roller shaft 31 and a plurality of roller brush assemblies 32, each roller brush assembly 32 is fixed to the roller shaft 31 at intervals along the circumferential direction of the roller shaft 31, and the roller brush assembly 32 is provided with a plurality of ballast removal rods 321 arranged at intervals, and the ballast removal rods 321 are used to remove ballast through the rotation of the roller shaft 31. Specifically, the roller shaft 31 can realize the rotational connection between the ballast removal roller brush 30 and the adjustment frame 20, and the driving device of the rail vehicle is connected to the roller shaft 31, and the roller brush assembly 32 is driven to rotate by driving the roller shaft 31 to rotate, and the roller brush assembly 32 realizes ballast removal through the plurality of ballast removal rods 321 arranged at intervals, and finally realizes the cleaning of the ballast inside the track.

[0038] In this embodiment, two ends of the roller shaft 31 are rotatably connected to the two connecting arms 21 respectively.

[0039] It can be understood that the adjustment module 40 can be a driving device such as a cylinder or a hydraulic cylinder. One end of the cylinder or hydraulic cylinder is hinged to the mounting base 10, and the driving end is hinged to the adjustment frame 20. By driving the adjustment frame 20 to extend or contract, the adjustment frame 20 is driven to rotate.

[0040] In one embodiment, Figures 1-2 As shown, the adjustment module 40 includes a supply connection member 41 and two adjustment members 42. The supply connection member 41 is located between the mounting seat 10 and the adjustment frame 20. One end of the two adjustment members 42 is connected to the supply connection member 41. The other ends of the two adjustment members 42 are respectively hinged to the mounting seat 10 and the adjustment frame 20. The supply connection member 41 is used to drive the two adjustment members 42 to move axially to drive the adjustment frame 20 to rotate. Specifically, the supply connection member 41 can realize the driving of the adjustment frame 20 to rotate by simultaneously extending and retracting the two adjustment members 42, or drive any of the adjustment frames 20 to extend and retract to realize the driving of the adjustment frame 20 to rotate.

The screw rod 421 is threadedly connected to the hinge joint 422. Only by controlling the adjusting member 42 to rotate relative to the adjusting member 42, the screw rod 421 can be extended or retracted into the adjusting member 42, thereby realizing the control of the rotation of the adjusting frame 20.

[0043] It can be understood that one end of the screw rod 421 is threadedly connected to the adjusting member 42, and the other end is threadedly connected to the hinge joint 422. Through this structure, the screw rod 421 can be controlled to rotate, and the screw rod 421 can be extended or retracted into the adjusting member 42 to achieve adjustment of the adjusting frame 20.

Specifically, through this arrangement, the screw rod 421 can be driven to extend or retract the adjustment frame 20 by simply rotating the adjustment member 42, which facilitates the height adjustment of the ballast roller brush 30.

[0045] In one embodiment, since a large amount of ballast will be lifted upwards during the ballast cleaning process by the ballast removal roller brush 30, in order to prevent the lifted ballast from hitting the vehicle and causing damage to the rail vehicle, Figure 1 As shown, the track ballast cleaning device further includes a stone retaining frame 50, which is fixed to the mounting seat 10 and extends toward the direction of the ballast removal roller brush 30, and the stone retaining frame 50 is provided with a plurality of passing gaps 51 for each ballast removal rod 321 to pass through. Specifically, the stone retaining frame 50 can block the ballast raised during the ballast removal process of the ballast removal roller brush 30, thereby effectively preventing the ballast from causing damage to the rail vehicle, and the passing gaps 51 can prevent the stone retaining frame 50 from blocking the rotation of the ballast removal roller brush 30.

[0046] In this embodiment, the stone retaining frame 50 is arranged to be inclined, so as to facilitate the ballast falling on the stone retaining frame 50 to fall on the track, and to prevent the ballast from being accumulated on the stone retaining frame 50 .

[0047] In one embodiment, Figure 1 As shown, the stone retaining frame 50 includes a connecting beam 52 and a plurality of stone retaining rods 53. Both ends of the connecting beam 52 are fixed to the adjusting frame 20. The stone retaining rods 53 are fixed to the connecting beam 52 at intervals and extend toward the direction of the ballast removal roller brush 30. A gap 51 for passing through is formed between adjacent stone retaining rods 53. Specifically, the connecting beam 52 can effectively strengthen the strength of the adjusting frame 20 and prevent the adjusting frame 20 from being deformed by being fixed to the adjusting frame 20 while achieving the fixing of the stone retaining rods 53. The stone retaining rods 53 can effectively block the raised ballast and form a gap 51 for passing through, which is convenient for the installation of the ballast removal rods 321.

[0048] In this embodiment, two ends of the connecting beam 52 are respectively fixed to two adjusting arms.

[0049] In one embodiment, Figure 1 As shown, the stone retaining frame 50 further includes a pressing plate 54, which is pressed on one end of the stone retaining rod 53 fixed to the connecting beam 52 and is fixedly connected to the connecting beam 52. Specifically, the pressing plate 54 can realize a stable connection between the stone retaining rod 53 and the connecting beam 52, and prevent the stone retaining rod 53 from being deformed or falling off from the connecting beam 52 under the impact of ballast.
