[0025] Figure 1 Structural schematic diagram of a rail sand and snow removal device provided by an embodiment of the present application; Figure 2 Rear view of a rail sand and snow removal device provided by an embodiment of the present application; as Figure 1 and Figure 2 As shown, in view of the above problems, an embodiment of the present application provides a rail sand and snow removal device, including: a frame 10, and two traveling wheels 101 adapted to the track are arranged at the bottom of the frame 10; the two traveling wheels can roll along the extending direction of the track, so as to drive the sand and snow removal device to perform sand and snow removal operations along the track.

[0026] Figure 3 Structural schematic diagram of a hood of a rail sand and snow removal device provided by an embodiment of the present application, as Figure 3 As shown, a hood 20 is connected to the frame 10. Side scrapers 202 are arranged on both sides of the housing of the hood 20. The side scrapers are connected to the housing of the hood through cross beams. The side scrapers 202 are inclined backward at an angle of 30° with respect to the sleeper. The side scrapers 202 scrape the accumulated sand and particulate matter on both sides of the track in a direction away from both sides of the track. Sand and snow removal are carried out near both sides of the track to prevent the accumulated sand and particulate matter on both sides of the track from falling into the track after sand and snow removal on the track, resulting in incomplete cleaning.

[0027] Openings are arranged on one side of the hood 20 away from the traveling wheels 101 and at the bottom of the hood 20.

[0028] Figure 4 Structural schematic diagram of a fan assembly of a rail sand and snow removal device provided by an embodiment of the present application, as Figure 4 As shown, a spiral assembly 30 is arranged in the housing of the hood 20, and at least one first through hole 201 is arranged on the housing of the hood 20; the first through hole 201 is communicated with the air inlet 401 of the fan assembly 40. The arrangement of the openings increases the contact area between the spiral assembly and the accumulated sand and particulate matter, and performs thorough sand and snow removal operations on the track.

[0029] Specifically, one end of the first through hole connected to the air inlet is provided with a connecting piece, and at least two waist-shaped holes are uniformly arranged on the connecting piece; bolt holes corresponding to the number and position of the waist-shaped holes are arranged at the air inlet end, and the waist-shaped holes and the bolt holes are connected together by bolts in a threaded manner. The angle of the fan assembly with respect to the hood is adjusted through the waist-shaped holes to meet the usage requirements in different situations.

[0030] The spiral assembly 30 sucks the accumulated sand and particulate matter on the track into the air inlet 401 of the fan assembly 40 through the first through hole 201, and the air outlet 402 of the fan assembly 40 throws the accumulated sand and particulate matter outside the track.

[0031] The sand and snow removal device provided in the embodiment of the present application performs sand and snow removal operations along the extending direction of the track through the walking wheels. The spiral assembly rotates to gather the accumulated sand and particulate matter on the track around the first through hole. The air inlet of the fan assembly sucks it into the interior of the fan assembly, and then, due to the advantage of the long throwing distance at the air outlet, the accumulated sand and particulate matter are thrown to a designated position outside the track, exposing the track, thereby completing the sand and snow removal operations on the track. The sand and snow removal device has the advantages of simple structure, small volume, and short protruding part at the air outlet, will not exceed the building clearance, will not touch the catenary, and can perform construction operations without power-off of the catenary. Moreover, it can meet the usage requirements of timely sand and snow removal, prevent train derailment, ensure the opening of the railway line, prevent damage caused by long-term accumulation of sand particles on the track, improve the line quality, and ensure the safety of train operation. At the same time, during the sand and snow removal operations, manual sand and snow removal are not required, which is safer, time-saving, and labor-saving.

[0032] Further, an impeller 403 is arranged inside the housing of the fan assembly 40. The impeller 403 is driven to rotate by the second driving assembly 404. The output end of the second driving assembly 404 passes through the bearing seat arranged on the fan housing 40 and is connected to the impeller 403.

[0033] Specifically, the second driving assembly is a driving motor, which drives the impeller to rotate at a high speed, thereby sucking the accumulated sand and particulate matter near the first through hole into the interior of the fan assembly through the air inlet, and throwing them outside the track through the air outlet of the fan assembly.

[0034] Figure 5 It is a schematic structural diagram of the spiral assembly of a sand and snow removal device on the track provided in the embodiment of the present application. As Figure 5 shown, further, the spiral assembly 30 includes a spiral shaft 301. Both ends of the spiral shaft 301 are connected to the housing of the hood 20 through the first bearing seats; one end of the spiral shaft 301 passes through the first bearing seat and is connected to the output end of the first driving assembly 302.

[0035] Specifically, the first driving assembly is a driving motor, which drives the spiral shaft to rotate smoothly.

[0036] Further, a left-handed thread 3011 and a right-handed thread 3012 are arranged on the outer wall of the spiral shaft 301 inside the housing of the hood 20 in opposite directions; both the left-handed thread 3011 and the right-handed thread 3012 are connected to the spiral shaft 301 through the reinforcing ribs 3013.

[0037] The driving motor drives the spiral shaft to rotate, and the left-handed thread and the right-handed thread rotate in opposite directions, thereby gathering the accumulated sand and particulate matter on the track towards the middle of the sleeper.

[0038] Further, two first through holes 201 are provided on the housing of the hood 20; the air outlets 402 of the blower assemblies 40 connected to the two first through holes 301 are arranged in opposite directions, and the two air outlets 402 throw the accumulated sand and particulate matter on the track to both sides of the track.

[0039] The two blower assemblies respectively connected to the two first through holes perform thorough sand and snow removal operations on the track, and can meet the usage conditions where there is a large amount of accumulated sand and particulate matter on the track. The air outlets being arranged in opposite directions can throw the accumulated sand and particulate matter to both sides of the track, preventing the accumulated sand and particulate matter from falling near the track when thrown to the same side of the track and affecting the sand and snow removal effect.

[0040] Specifically, the two first through holes are respectively arranged on the housing of the hood near the left-handed thread and the housing of the hood near the right-handed thread, so that the accumulated sand and particulate matter gathered by the left-handed thread and the right-handed thread can conveniently enter the blower assembly through the first through holes.

[0041] The embodiment of the present application also provides a rail sand and snow removal vehicle, including a sand and snow removal vehicle body, and a sand and snow removal device is provided on the sand and snow removal vehicle body; the sand and snow removal device is the sand and snow removal device described in any of the above contents.

[0042] Further, at least one lifting oil cylinder 50 is provided on the frame 10, and the frame 10 is hinged to the telescopic rod end of the lifting oil cylinder 50; the cylinder end of the lifting oil cylinder 50 is hinged to the sand and snow removal vehicle body. The sand and snow removal vehicle can conveniently control the lifting of the sand and snow removal device in the vertical direction by controlling the lifting oil cylinder.

[0043] Further, at least one transverse movement oil cylinder 60 is provided on the frame 10, and the frame 10 is hinged to the telescopic rod end of the transverse movement oil cylinder 60; the cylinder end of the transverse movement oil cylinder 60 is hinged to the sand and snow removal vehicle body. The sand and snow removal vehicle can conveniently control the movement of the sand and snow removal device along the direction parallel to the sleeper by controlling the transverse movement oil cylinder.

[0044] Figure 6 It is a schematic connection structure diagram of a rail sand and snow removal device and a moving component provided by the embodiment of the present application, as Figure 6 shown. Further, at least one moving component 70 is provided on the frame 10; the moving component 70 includes a first connecting vertical plate 701 connected to the frame 10, connecting rods 702 are respectively hinged to the upper and lower ends of the first connecting vertical plate 701, and one ends of the two connecting rods 702 far from the first connecting vertical plate 701 are both hinged to a second connecting vertical plate 703; the top of the second connecting vertical plate 703 is hinged to the sand and snow removal vehicle body.

[0045] Specifically, two moving components 70 are provided on the frame, and the first connecting vertical plates of the two moving components 70 are evenly arranged on the frame 10. The two moving components are used in cooperation to conveniently adjust the angle of the sand and snow removal device, so that the sand and snow removal device performs sand and snow removal operations along the extending direction of the track.

[0046] Working principle:

[0047] When it is necessary to perform sand and snow removal treatment on the track, the sand and snow removal vehicle adjusts the position and angle of the sand and snow removal device in the track extending direction and the direction parallel to the sleeper through the moving components and the transverse moving oil cylinder, and then adjusts the position of the sand and snow removal device in the vertical direction through the lifting oil cylinder to perform sand and snow removal on the track. The driving motor drives the spiral shaft to rotate, and the left-handed thread and the right-handed thread gather the accumulated sand and particulate matter on the track near the two first through holes respectively. Then, the air inlet of the fan assembly sucks the accumulated sand and particulate matter into the interior of the fan assembly, and then throws them to both sides of the track through the air outlet of the fan assembly. At the same time, the side scrapers on both sides of the hood scrape the accumulated sand and particulate matter on both sides of the track in a direction away from both sides of the track, thus completing the sand and snow removal operation.
