Description

Technical Field

[0001] This application relates to the field of track snow removal equipment technology, and in particular to a snow removal and ice breaking device for steel rails. Background Technology

[0002] The role of rail transit in accelerating economic and social development is becoming increasingly prominent. Especially in winter, railways frequently face challenges from ice and snow. On the one hand, snow and ice accumulation on the rails increase the coefficient of friction between the rails and wheels, accelerating wear on the rail surface and wheels. Accumulated snow particles can also cause wheel slippage and abnormal braking distances. On the other hand, fasteners, as intermediate connecting parts between the rails and sleepers, play a crucial role in fixing the rails to the sleepers, maintaining track gauge, and preventing longitudinal and lateral movement of the rails relative to the sleepers. Snow burying the track bed slab and rail fasteners prevents railway workers from properly inspecting whether fasteners are loose or rails are broken. The lack of timely inspection and maintenance of fasteners poses a serious threat to the safe operation of rail transit.

[0003] Among related technologies, solutions for rail snow removal are mainly divided into four categories: manual snow removal, mechanical snow removal, chemical snow melting, and electric heating or hot air snow removal. However, all of these methods have significant drawbacks. For example, manual snow removal is inefficient and costly, and poses safety hazards in harsh environments. Mechanical snow removal equipment (such as snowplows and snow blowers) can easily damage the fastener structure, and these devices are also bulky, expensive, and unable to effectively remove snow from the gaps in the fasteners on the rails. Using chemical snow melting agents not only easily corrodes the metal components of the rails and fasteners, but also easily pollutes the environment. Using electric heating equipment for snow removal faces challenges such as high energy consumption, complex equipment deployment, and high maintenance costs. Utility Model Content

[0029] According to the embodiments of this application, refer to Figures 1 to 5 As shown, a snow removal and ice breaking device for steel rails is provided, including: a frame 1, two wheels 2, an ice crushing component 3, an ice scraping component 4, a snow blowing component 6, and a handle 7.

[0030] Among them, reference Figure 1 and Figure 5 As shown, two wheels 2 are arranged at the bottom of the frame 1 along the front-rear direction. The outer circumferential surface of each wheel 2 has an annular groove 201 that is collinear with the wheel axle of the wheel 2. The width of the annular groove 201 is adapted to the width of the rail 8, and the rail 8 can be inserted into the annular groove 201.

[0031] refer to Figure 1 and Figure 3 As shown, the ice-crushing assembly 3 is fixedly connected to the front of the frame 1, and includes a housing 301, a blade shaft 302, and a spiral blade 303. The lower part of the housing 301 is open, the blade shaft 302 is rotatably connected to the housing 301, and the blade shaft 302 is perpendicular to the traveling direction of the frame 1. The spiral blade 303 is fixedly connected to the blade shaft 302, and the cutting edge of the spiral blade 303 protrudes from the lower edge of the housing 301.

[0032] refer to Figure 3 As shown, the ice scraping assembly 4 is fixedly connected to the front end of the housing 301. The ice scraping assembly 4 includes two ice scraping plates 401 that are V-shaped when projected on the horizontal plane, and the opening of the V-shape faces the frame 1.

A handle 7 is fixedly connected to the rear of the frame 1.

[0035] In the above embodiment, since the outer circumferential surface of the wheel 2 is provided with an annular groove 201, when clearing the snow and ice from the rail 8, both wheels 2 are placed on the rail 8 at the same time, and the rail 8 can be inserted into the annular groove 201. The worker holds the handle 7 and pushes the frame 1 forward along the rail 8, and starts the power component 5. Since the ice scraping component 4 is located at the front end of the housing 301, the two V-shaped ice scraping plates 401 can push the snow on the rail 8 off the rail 8. Then, the blade shaft 302 in the ice crushing component 3 rotates under the drive of the power component 5, which drives the spiral blade 303 connected to the blade shaft 302 to rotate, breaking up the ice that has frozen on the rail 8 and pushing it laterally under the rail 8. Finally, the snow blowing component 6 blows away the snow and ice on both sides of the rail 8 through the left air outlet 602 and the right air outlet 603, thereby clearing the snow and ice on both sides of the rail 8. The snow removal and ice breaking device for rail 8 of this application can easily remove snow and ice from rail 8, and can also clear snow and ice from both sides of rail 8, thus facilitating the maintenance of rail 8 fasteners by staff.

The first servo motor is used to drive the connecting rod 604 to rotate, so that the left air outlet 602 and the right air outlet 603 swing left and right. The second servo motor is used to drive the left-hand pivot 605 to rotate, so that the left air outlet 602 swings up and down. The third servo motor is used to drive the right-hand pivot 606 to rotate, so that the right air outlet 603 swings up and down. With this design, the left air outlet 602 and the right air outlet 603 can swing left and right, and can also swing up and down. By controlling the first, second, and third servo motors, multi-directional air blowing can be achieved.

This design allows hot air to be blown out from the left air outlet 602 and the right air outlet 603, thus facilitating the melting of snow on both sides of the rail 8. In the case where the power assembly 5 is a fuel engine 501, the main air outlet duct of the blower can be designed to pass through the outer wall of the combustion chamber of the fuel engine 501, thereby utilizing the heat from the fuel engine 501.

[0041] According to the embodiments of this application, refer to Figures 1 to 5 As shown, each of the ice scraping plates 401 has a tungsten carbide wear-resistant layer on its outer surface, and the spiral blade 303 has a tungsten carbide wear-resistant layer on its outer surface.
