[0024] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] In order to solve the technical problem that highway snow removal equipment cannot be directly applied to railway snow removal, the present invention provides a disaster prevention and control highway-rail dual-purpose vehicle, which can realize that highway snow removal equipment is directly applied to railway snow removal.

[0026] Please refer to Figure 1-2 , Figure 1This is a schematic structural diagram of a disaster prevention and control road-rail dual-purpose vehicle in an embodiment of the present utility model. The disaster prevention and control road-rail dual-purpose vehicle includes a road vehicle body 1, a rail running mechanism 2, and a snow removal mechanism 3; the rail running mechanism 2 includes a lifting and guiding frame 21 and guiding wheels 22. A plurality of the guiding wheels 22 are all arranged on the lifting and guiding frame 21. The lifting and guiding frame 21 is used to lift and lower the guiding wheels 22, and make the guiding wheels 22 have a position state of descending and fitting the railway track for railway transportation, and a position state of lifting and being higher than the bottom of the wheels of the road vehicle body 1 for road transportation, enabling the switching between road driving and railway driving. The guiding wheels 22 are large-diameter high-rim steel guiding wheels with a rolling circle of Φ400mm and a rim of Φ460mm to ensure high-speed performance on the track. The lifting and guiding frame 21 is lifted and lowered by a 90-degree rotation for the lifting and lowering of the guiding wheels 22; the snow removal mechanism 3 includes a snow shoveling assembly 31, a snow melting assembly 32, and a snow sweeping assembly 33. The snow shoveling assembly 31, the snow melting assembly 32, and the snow sweeping assembly 33 are arranged along the axis of the vehicle body and are arranged in sequence from left to right at the front of the road vehicle body 1, forming a snow removal step of shoveling snow first, then melting snow, and then sweeping snow during driving. A large amount of snow is quickly removed by shoveling snow. For the remaining thin layer of snow or ice after shoveling snow, using hot melting can melt these difficult-to-shovel parts faster. The water or diluted snow after melting can be removed by snow sweeping equipment to ensure that there are no residues affecting traffic. By the snow removal step of shoveling snow first, then melting snow, and then sweeping snow, the long-term action of snow melting agents on infrastructure such as tracks and road surfaces can be avoided, reducing the corrosion risk. Moreover, through the front and back actions of shoveling snow, melting snow, and sweeping snow, the wear on the track and road surface can be reduced. By combining the use of this series of steps of shoveling snow, melting snow, and sweeping snow, the snow removal requirements of both roads and railways can be adapted simultaneously.

[0027] It should be noted that the road vehicle body 1 can adopt a mature model of a Mercedes-Benz national VI chassis for automobiles.

[0028] In one of the embodiments, please refer to Figure 1 , in order to shovel snow that can fit both railways and roads, the snow shoveling assembly 31 includes a scraper 311, a frame 312, and a deflection and pitch angle driving member 313. The frame 312 is fixed to the front of the road vehicle body 1. The deflection and pitch angle driving member 313 is installed on the frame 312. The movable end of the deflection and pitch angle driving member 313 is connected to the scraper 311, and is used to drive the scraper 311 to deflect horizontally and adjust the pitch. By adjusting the pitch, the lifting and pressing of the scraper 311 are controlled to fit the railway or the road. By horizontal deflection, the scraper 311 is controlled to roll to both sides of the two roads.

[0029] In this embodiment, the scraping plate 311 is also hinged to the frame 312 both in the vertical and horizontal planes, allowing it to rotate in both the vertical and horizontal planes. The deflection and pitch angle driving member 313 can adopt two sets of hydraulic telescopic structures. The hydraulic telescopic structures are hinged to both the frame 312 and the scraping plate 311. One set has a telescopic direction in the horizontal plane, and drives the scraping plate 311 to deflect in the horizontal plane through telescoping. One set of hydraulic telescopic structures telescopes in the vertical plane, driving the scraping plate 311 to pitch in the vertical plane. The above structures are all mature structural features for rotational adjustment in the art and will not be elaborated here; in addition, for the deflection and pitch angle driving member 313, other structures in the art that can achieve the same effect can also be used, and it is not uniquely limited here.

[0030] In one of the embodiments, please refer to Figure 1 , for snow cleaning, the snow sweeping assembly 33 includes a baffle 331, a lifting driving member 332, and a brush roller 333. The lifting driving member 332 is installed at the front of the road vehicle body 1. The movable end of the lifting driving member 332 is connected to the baffle 331. The brush roller 333 is rotatably connected to the side of the baffle 331 away from the scraping plate 311.

[0031] Furthermore, the baffle 331 is in an L shape.

[0032] In this embodiment, the lifting driving member 332 can adopt a hydraulic cylinder push rod or an electric push rod or other devices with a telescopic function, as long as it can achieve the purpose of driving the lifting of the baffle 331 and the brush roller 333.

[0033] In one of the embodiments, please refer to Figure 1 , the snow melting assembly 32 includes a hot air blower 321 and a guiding nozzle 322. The hot air blower 321 is installed on the side of the baffle 331 close to the scraping plate 311. The guiding nozzle 322 is installed on the air outlet of the hot air blower 321. Hot air is formed by the hot air blower 321, and the hot air is guided onto the track through the guiding nozzle 322. The equipped powerful blower can generate high-pressure air flow, concentrating and blowing out the hot air heated to a high temperature at high speed. This concentrated and powerful air flow not only quickly melts the snow layer and ice layer, but also effectively blows them off the track surface through the blowing action, ensuring the thoroughness and rapidity of the snow removal effect. The blowing guiding nozzle 322 ensures that the hot air can accurately act on the snow layer and ice layer by precisely adjusting the air flow direction, avoiding waste of energy and unnecessary damage. This precisely guiding function enables the snow melting assembly 32 to maintain an efficient and stable working state in the complex and changeable railway environment.

[0034] Furthermore, the snow melting assembly 32 and the snow sweeping assembly 33 are also arranged at the bottom of the rear of the road vehicle body 1, so as to form a double snow melting and snow removal to avoid incomplete snow melting and snow removal.

[0035] In one embodiment, see Figure 2 The lifting guide frame 21 includes a fixed seat 211, a cross beam 212 and a hydraulic cylinder push rod 213. The fixed seat 211 is connected to the bottom of the highway vehicle body 1. The two cross beams 212 are respectively hinged on both sides of the fixed seat 211. The two ends of the two hydraulic cylinder push rods 213 are respectively hinged to the two cross beams 212. The hydraulic cylinder push rod 213 is a double-headed hydraulic push rod. A plurality of guide wheels 22 are evenly distributed on the two cross beams 212.

[0036] It can be understood that in order to improve safety, the lifting guide frame 21 can be equipped with two sets of safety structures, namely a mechanical locking structure and a hydraulic locking structure, when running on track. The mechanical locking structure can adopt a snap-on locking structure to achieve locking through mutually cooperating grooves and protrusions, and the hydraulic locking structure is locked by a hydraulic cylinder.

[0037] Furthermore, the number of the rail traveling mechanisms 2 is at least two, wherein the guide wheels 22 on one of the rail traveling mechanisms 2 are transmission-connected to the engine output end of the road vehicle body 1 through a combined gearbox, wherein the front one is the front guide part, and the rear one is the rear guide drive part, and the power is mainly transmitted to the guide wheels 22 on the rail traveling mechanism 2 of the rear guide drive part through the engine as the drive for railway travel.

[0038] In one embodiment, see Figure 1 A lifting mechanism 4 is provided on the top of the highway vehicle body 1, and a deicing mechanism 5 is provided at the lifting end of the lifting mechanism 4. The deicing mechanism 5 is used for deicing the contact line, wherein the lifting mechanism 4 can adopt a scissor-type lifting platform, and the deicing mechanism 5 can adopt a non-metallic strip driven by a motor to crush and de-ice the ice by impact.

[0039] Furthermore, a magnetic attraction mechanism 6 is provided at the bottom of the highway vehicle body 1, and the magnetic attraction mechanism 6 is used to magnetically attract metal foreign objects. The cleaning and maintenance of the roadbed is a key link to ensure the safety of train operation and the long-term stability of the track system. The metal garbage, iron slag and other magnetic foreign objects on the roadbed can be cleaned. Specifically, an automated conveyor belt can be used, on which an electromagnet is provided, and the electromagnet is turned on and demagnetized by power off. The metal foreign objects are magnetically attracted and moved to a receiving hopper under the guidance of the conveyor belt. The power is cut off in the receiving hopper, and the metal foreign objects fall into the receiving hopper.

[0040] Furthermore, a cold laser emitter may be provided on the top of the highway vehicle body 1 for emitting a cold laser beam to clean foreign matter on the contact network.

[0041] In order to better understand the present invention, the following Figures 1 to 2The technical solution of the present utility model will be described in detail: If it is for road driving, the lifting guide frame 21 raises the guide wheel 22 above the wheels, and uses the wheels on the body of the road vehicle 1 as the driving part to make contact and drive on the road. If it is for rail driving, the lifting guide frame 21 lowers the guide wheel 22 to contact the track to form a support, and uses the guide wheel 22 as the driving part to drive on the rail; During driving, first lower the scraping plate 311 to fit to an appropriate height position on the road or rail to shovel snow, and at the same time lower the snow melting component 32 and the snow sweeping component 33, make the brush roller 333 on the snow sweeping component 33 contact the road surface or rail, and make the guide nozzle 322 abut against the ground or the upper surface of the rail. During driving, an action coordination of shoveling snow first, then melting snow, and then sweeping snow is formed, and at the rear of the vehicle, steps of melting snow and sweeping snow will be carried out again to improve the effect of snow and ice removal.

[0042] The specific implementation manners of the present utility model described above do not constitute a limitation on the protection scope of the present utility model.
