Description

Technical Field

[0001] The utility model relates to the technical field of railway snow-clearing and ice-removing mechanical equipment, and in particular to a snow-clearing vehicle capable of clearing ice from railway overhead power supply cables. Background Art

[0002] The northern part of my country enters the snow season in winter, and the average time span is about 5 months. After the heavy snowfall, the normal traffic order of traffic roads and railways is greatly affected. If it rains and blows, causing snow and ice, the road will be closed and suspended, causing serious social and economic losses. Especially when railway traffic encounters ice and snow accumulation, because the track bed is paved with stone piles. Once the common highway mechanized roller brush or shovel is used to clear the snow on the rails, the stone piles on the roadbed will become loose, and the rails will be lifted, seriously endangering the normal passage of trains. Therefore, in the prior art, manual methods are often used to clear the snow on the railway roadbed, and the cleaning effect and efficiency are extremely backward.

[0003] In addition, when a major ice and snow disaster occurs, which causes ice to get stuck on the high-voltage contact network of the railway, causing the entire network to be insulated and powered off, and electric locomotives and trains to stop running, the ice is often removed by having a large number of people standing on the lifting platform and hitting the cables with wooden sticks, which is not only inefficient, but also poses a great safety hazard.

[0004] In the prior art, Chinese patent CN202321718228.5 discloses a snow-clearing vehicle capable of breaking ice, comprising a railway flatbed train, a water jet bracket, a lifting mechanism, a water jet control box, and at least two groups of water cutting devices; the water jet bracket comprises two connecting rods, two groups of universal wheels, and a tension spring, and connecting frames are installed on the tops of the two groups of universal wheels, and rotating shafts are fixedly provided on the side walls on both sides of the nozzle, one end of the connecting rod is fixedly connected to the connecting frame on the corresponding side, and the other end of the connecting rod is rotatably sleeved on the outer side of the rotating shaft on the corresponding side; the cutting nozzle of the first group of water cutting devices extends to the connecting frame, and the cutting nozzle of the second group of water cutting devices extends to the lifting end of the lifting mechanism.

[0005] The above patent aims at the ice-covered cables through the cutting nozzle at the lifting end of the lifting mechanism. However, the current railway overhead power supply cables are not installed in a straight line in the center, but in a continuous S-shape. The cutting nozzle at the lifting end of the lifting mechanism swings back and forth. The cutting nozzle at the lifting end of the lifting mechanism cannot continuously and accurately break the ice on the overhead cables, resulting in intermittent leakage and the ice cannot be completely cleared.

[0033] A snow-clearing vehicle capable of clearing ice from railway overhead power supply cables comprises a vehicle body 1, at least one lifting bow 2 and at least one track ice-clearing mechanism 3. In this embodiment, the snow-clearing vehicle is provided with two lifting bows 2 and one track ice-clearing mechanism 3.

[0034] like Figure 1As shown, the vehicle body 1 includes a vehicle frame 11, a front cab 12, a rear cab 13, a power unit 14, a water jet control box 15, and a heating control box 16. The front cab 12 and the rear cab 13 are respectively arranged on the front and rear sides of the top of the vehicle frame 11, and the power unit 14, the water jet control box 15, and the heating control box 16 are arranged between the front cab 12 and the rear cab 13.

[0035] The power unit 14 is used to provide power for the vehicle body 1 to move and to provide energy for the entire vehicle. In this embodiment, the power unit 14 is a generator set.

[0036] The two lifting pantographs 2 are respectively arranged on the top of the front cab 12 and the rear cab 13. The lifting pantograph 2 of this embodiment can use the existing pantograph structure, which is easy to implement and can be widely used for deicing overhead cables 4 in various railway working conditions.

[0037] Specifically, each lifting bow 2 includes a base 21, a lower arm 22, a pull rod 23, an upper arm 24, a balance rod 25, a bow head support 26 and a bow head bracket 27. The upper ends of the lower arm 22 and the pull rod 23 are inclined to the same side, and the upper ends of the upper arm 24 and the balance rod 25 are inclined to the opposite side.

[0038] The lower end of the lower arm 22 is hinged to the base 21, and the upper end of the lower arm 22 is hinged to the upper arm 24. The lower end of the pull rod 23 is hinged to the base 21, and the upper end of the pull rod 23 is hinged to the lower end of the upper arm 24. The bow head support 26 is vertically arranged, and the upper end of the upper arm 24 is hinged to the upper part of the bow head support 26, and the upper end of the balance rod 25 is hinged to the bottom end of the bow head support 26. The bow head bracket 27 is arranged on the top of the bow head support 26.

[0039] A first water jet 28 is disposed on each of the left and right sides of the top of the bow head bracket 27. The two first water jets 28 are coaxially disposed horizontally. The first water jets 28 are located on the same horizontal plane as the overhead cable 4 and are disposed on both sides of the overhead cable 4 respectively. The first water jets 28 are symmetrically disposed on both sides of the lifting bow 2, and the openings of the first water jets 28 are all facing the central axis surface of the lifting bow 2.
