Description

Technical Field

[0001] The utility model relates to the technical field of rail transportation, in particular to a rail deicing device. Background Art

[0002] With the huge growth of people's travel needs, rail transit has become the first choice for many people to travel long distances due to its high efficiency and stability. At the same time, with the diversification and intelligent development of railway technology, the types of rail transit have also become richer, and various modes of transportation such as railways, subways, light rails and trams have developed rapidly. However, in extreme weather, outdoor tracks are prone to ice, which makes trains at risk of slipping and derailing, seriously endangering people's lives and property. Therefore, it is necessary to study the de-icing of tracks.

[0003] In the prior art, railway track deicing is generally done manually, which is inefficient and labor-intensive, and poses a threat to human safety in extreme weather. At the same time, some deicing devices remove ice by heating or knocking, reducing manual participation. However, in severe conditions such as snow accumulation or freezing rain, the efficiency of deicing by this method is low, and frozen ice is easily formed on the side of the track, making it difficult for the snow removal device to move. Therefore, in order to solve the above problems, a track deicing device is proposed in this application. Utility Model Content

[0011] (III) Beneficial effects

[0012] The utility model provides a track deicing device, which has the following beneficial effects:

[0013] (1) In the present invention, a snowplow is fixedly installed at the front end of the chassis, which can push the snow or other contaminants attached to the rails to both sides of the rails in advance, so that the de-icing device at the rear can directly knock the ice on the top of the rails, thereby improving the efficiency and effect of breaking ice.

[0014] (2) In the present invention, the positioning wheels on both sides of the chassis can control the degree of compression of the adjusting spring by adjusting the adjusting nut, thereby controlling the distance between the positioning wheels and the track. Under extreme conditions, when there are ice or other obstacles on the side of the track, the positioning wheels fixed on the C-shaped arm can adaptively increase the distance between the positioning wheels and the track by compressing the adjusting spring, ensuring that the de-icing device can work smoothly on the track.

[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0025] An embodiment of a track deicing device of the utility model is as follows Figures 1 to 5 As shown, a track deicing device of the utility model comprises a chassis 2, a positioning and adjusting structure, and a snow shovel 11. The snow shovel 11 is fixedly installed at the front end of the chassis 2, and an adjusting rod 5 is fixedly installed on the side of the chassis 2. A slidable C-shaped hanging arm 6, an adjusting spring 3 and an adjusting nut 4 are sequentially installed on the adjusting rod 5, and one side of the adjusting spring 3 is pressed and contacted with the adjusting nut 4. A connecting rod 7 is fixedly installed below the C-shaped hanging arm 6, and a retaining frame 8 is installed on the connecting rod 7. A positioning wheel 9 is fixedly installed on the retaining frame 8, and the positioning wheel 9 contacts the side of the track 10. A rotatable ice-breaking bucket transmission shaft 15, a fixedly mounted electric motor 17 and a bearing seat 18 are installed inside the chassis 2; an ice-breaking bucket 13 is installed on the ice-breaking bucket transmission shaft 15; an ice-breaking nail 14 is fixedly mounted on the ice-breaking bucket 13; the ice-breaking nail 14 contacts the upper surface of the track 10 when in the lowest position of rotation; a rotating shaft 19 is fixedly mounted on the bearing seat 18; a traveling roller 12 is fixedly mounted on the rotating shaft 19; the traveling roller 12 contacts the upper surface of the track 10.

[0026] In this embodiment, the snow shovel 11 is fixedly installed at the front end of the chassis 2 and there is a 1 cm gap between it and the track 10. Since the snow shovel is installed at the front end of the de-icing device, the snow or other contaminants attached to the track can be pushed away from the track in advance, so that the ice breaking device 14 at the rear can directly act on the ice, thereby improving the efficiency and effect of de-icing.

[0027] The cam 8 is fixed to the bottom of the adjusting rod 5 and the adjusting nut 4 is pressed against the adjusting nut 4. A connecting rod 7 is fixedly installed below the C-shaped arm 6, and a retaining frame 8 is installed on the connecting rod 7. A positioning wheel 9 is fixedly installed on the retaining frame 8. The positioning wheel 9 contacts the side of the track 10. When there is an obstacle on the side of the track, the positioning wheel 9 will move outward under the action of the obstacle, and the positioning wheel 9 is fixed on the C-shaped arm 6 through the retaining frame 8 and the connecting rod 7. Therefore, the C-shaped arm 6 will move outward on the adjusting rod 5, but the outer adjusting nut 4 is fixed, so the C-shaped arm 6 can only be displaced outward by compressing the adjusting spring 3. At this time, the positioning wheel 9 is in sufficient contact with the side of the track, which ensures the stable operation of the device. When the obstacle is passed, the compressed spring will rebound so that the positioning wheel 9 continues to maintain sufficient contact with the track.

[0028] In this embodiment, a rotatable ice-breaking bucket drive shaft 15 is installed inside the chassis 2, and an ice-breaking bucket 13 is installed on the ice-breaking bucket drive shaft 15. Ice-breaking nails 14 are fixedly installed on the ice-breaking bucket 13. The ice-breaking nails 14 are in contact with the upper surface of the track 10 when in the lowest position of rotation, which can ensure that the ice on the track can be effectively removed.

[0029] In this embodiment, a rotating shaft 19 is fixedly mounted on the bearing seat 18, and a traveling roller 12 is fixedly mounted on the rotating shaft 19. The traveling roller 12 contacts the upper surface of the track 10, and anti-slip material is provided on the traveling roller 12 to ensure that the de-icing device has sufficient forward power.

[0030] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
