Description

Technical Field

[0001] The invention relates to the technical field of road-rail dual-purpose tractor vehicles, and in particular to a novel road-rail dual-purpose vehicle. Background Art

[0002] A road-rail vehicle is a special vehicle that can run on railway tracks, on ordinary roads, or even in the wild. In the early days, it was mainly used for military purposes, but now it is mainly used for emergency tasks such as maintenance and rescue of railway lines and along the lines. A road-rail vehicle switches between road and railway driving modes through upper and lower rail devices, but the existing upper and lower rail devices have a complex structure and cannot accurately align with the rails, which affects the switching effect of the road-rail vehicle's driving mode.

[0003] In response to the above problems, a patent application document with application publication number CN112158765A discloses an upper and lower rail device and a road-rail dual-purpose vehicle, the road-rail dual-purpose vehicle comprising an upper and lower rail device and a frame fixed on a supporting mechanism of the upper and lower rail device, the upper and lower rail device comprising a base, a slewing mechanism, a lifting mechanism and a supporting mechanism, the base is mounted on the rail, the slewing mechanism is connected to the base and can rotate on the base, the lifting mechanism is fixed to the slewing mechanism and rotates driven by the slewing mechanism, the supporting mechanism is connected to the lifting mechanism, and the road-rail dual-purpose vehicle is carried on the supporting mechanism; when in use, the lifting mechanism is driven to rotate by the slewing mechanism, so that the lifting mechanism switches to different angles to achieve switching between different states on the rail and the road, the supporting mechanism can be telescoped and slid along the length direction of the road-rail dual-purpose vehicle to adjust the overlap of the center line between the road-rail dual-purpose vehicle and the rail, so as to achieve precise movement and positioning of the road-rail dual-purpose vehicle on the rail.

[0004] However, for the above-mentioned dual-purpose road-rail vehicle, although the supporting mechanism can extend and slide to adjust the centerline overlap, the accuracy and response speed of this mechanical adjustment are low and cannot meet the requirements of quickly switching driving modes; in addition, the above-mentioned dual-purpose road-rail vehicle uses the same set of wheels when traveling on rails and roads. The contact area between the wheels and the rails when traveling on rails is limited, and the hardness of the rails is high, which will cause serious wheel wear. If the wear is uneven or the friction between the wheels and the rails is insufficient, the vehicle will also be at risk of derailment. If high-hardness wheels are used to adapt to the rails, the road-rail vehicle will cause additional damage to the road surface due to the excessive hardness of the wheels when traveling on the road, which will not only increase the road maintenance cost, but also affect the driving safety of other vehicles. Summary of the invention

[0005] The invention provides a novel road-rail dual-purpose vehicle to solve the technical problem that the upper and lower rail devices in the prior art have low adjustment accuracy and response speed and cannot meet the requirement of fast switching of driving modes.

[0006] In order to solve the above problems, the new road-rail dual-purpose vehicle provided by the present invention adopts the following technical solutions: A new type of road-rail dual-purpose vehicle comprises: a vehicle body, the vehicle body comprising a chassis, a vehicle shell, a steering mechanism, a steering wheel and a vehicle body wheel, the vehicle shell is mounted on the chassis, the steering mechanism is mounted on the bottom of the chassis, both ends of the steering mechanism in the length direction are mounted with steering wheels, both ends of the chassis in the length direction are provided with a heavy-load telescopic structure, and the bottom end of the heavy-load telescopic structure is mounted with a vehicle body wheel; Also includes: The upper and lower rail devices are two in number, and each of the two ends in the length direction of the chassis has a groove protruding upward and opening downward, which is located on the inner side of the heavy-load telescopic structure. The two upper and lower rail devices are respectively installed in the two grooves. The upper and lower rail devices include a hollow heavy-load linear guide, a first upper and lower rail assembly, and a second upper and lower rail assembly. The hollow heavy-load linear guide is installed in the groove and extends along the width direction of the chassis. Two opposite sides of the hollow heavy-load linear guide are provided with relatively extended support platforms. The top surface of the hollow heavy-load linear guide is installed with the first upper and lower rail assembly, and the second upper and lower rail assembly is installed on the support platform. The first upper and lower rail assembly includes a support column, a support plate, a first running wheel and a telescopic adsorption structure. The number of the support columns is two. The two support columns are arranged opposite to each other and their top surfaces are connected through the support plate.

The bottom surface of the support plate is equipped with a telescopic adsorption structure for adsorbing the top surface of the hollow heavy-load linear guide rail. The second upper and lower rail assembly includes a load-bearing telescopic member, a telescopic adsorption structure and a second running wheel, the load-bearing telescopic member is fixedly mounted on the top surface of the steering mechanism, the top surface of the load-bearing telescopic member is mounted with a telescopic adsorption structure for adsorbing the top surface of the support platform, and two sets of second running wheels arranged oppositely are mounted on two opposite sides of the top surface of the load-bearing telescopic member; A displacement sensor and a controller are installed on the chassis, and the displacement sensor, the heavy-load telescopic structure and the telescopic adsorption structure are all connected to the controller signal.

An upper and lower rail device including a first upper and lower rail assembly and a second upper and lower rail assembly is installed at both ends of the chassis in the length direction. The first upper and lower rail assembly and the second upper and lower rail assembly both include a telescopic adsorption structure. A displacement sensor and a controller are installed on the chassis. The controller is connected with the telescopic adsorption structure, a signal receiver and a displacement sensor signal. The distance between the center of the steering wheel and the center of the railway track is accurately measured by the displacement sensor.

Compared with controlling the upper and lower rails of the road-rail dual-purpose vehicle by mechanical adjustment, the response speed is faster, the automation level is higher, and it is safer and more reliable. 2.

After that, the road-rail dual-use vehicle can travel on the railway rails, and the relative position between the first upper and lower rail assembly and the second upper and lower rail assembly is restored to the initial state, which can keep the force balance of the vehicle during the driving on the railway rails, and avoid the vehicle from rolling over due to unbalanced force. 3. By setting up independent steering wheels and body wheels, when running on the road, the body wheels are in contact with the road surface, and when running on the railway, the steering wheels are in contact with the rails. It can be adjusted according to different driving environments to ensure the stability of the road-rail dual-purpose vehicle under various road conditions, reduce unnecessary wear and tear, and thus increase the service life of the road-rail dual-purpose vehicle.

The first running wheel 12 drives the vehicle body 2, the chassis 1 and the structure installed on the chassis 1 to move to the initial relative position state with the steering mechanism, so as to avoid the vehicle body from rolling over due to uneven force during the driving on the rails; finally, the controller controls the bar electromagnet 37 of the first upper and lower rail assembly to be energized and descend until it is adsorbed on the top surface of the hollow heavy-load linear guide rail 7, and the road-rail dual-purpose vehicle can travel on the rails; When the road-rail dual-use vehicle travels from the rails to the road surface, the controller first controls the bar electromagnet 37 of the first upper and lower rail assembly to be powered off and lifted, then controls the first running wheel 12 to move to the middle position of the hollow heavy-load linear guide 7, and then controls the bar electromagnet 37 of the first upper and lower rail assembly to be lowered and powered on, so that it is adsorbed on the top surface of the hollow heavy-load linear guide 7; then controls the heavy-load telescopic structure 4 to extend downward, so that the vehicle body wheel 5 contacts the road surface, and then controls the electromagnet 19 of the rotating telescopic assembly 15 to be powered off, and the heavy-load telescopic structure 4 of the second upper and lower rail assembly to be powered on. The load-carrying telescopic structure 4 rises to drive the steering mechanism to rise until the steering wheel 3 leaves the rail, and then the bar electromagnet 37 of the second upper and lower rail device is controlled to be powered off, the telescopic rod 16 connected thereto is contracted, and the second running wheel 14 moves to the middle position of the hollow heavy-load linear guide 7; then, the bar electromagnet 37 of the second upper and lower rail assembly is powered on and lifted, and adsorbed on the support platform 8, and at the same time, the rotating telescopic assembly 15 rotates 180° counterclockwise to make the electromagnet 19 adsorbed on the magnet plate, and the road-rail dual-purpose vehicle can travel on the road; When the road-rail vehicle travels to a section without a level crossing or any section of ballasted or ballastless track, it directly travels onto the track through the off-road function of the vehicle wheels 5. At this time, there is no need to completely cover the vehicle body above the rails. It is only necessary to ensure that the vehicle body is parallel to the rails to perform the above-mentioned track-on operation.
