Embodiment 1

[0051] A specific embodiment of the present invention discloses a multi-drive mode vehicle capable of crossing vertical obstacles, including a vehicle body 1, a track and swing arm drive assembly 2, a tire drive assembly 3 and a rail wheel drive assembly 4, and the track and swing arm drive assembly 4. The arm driving assembly 2, the tire driving assembly 3 and the track wheel driving assembly 4 are arranged on the vehicle body.

[0052] The track and swing arm driving assembly 2 is used for crossing obstacles, the tire driving assembly 3 is used for running on a smooth road, and the track wheel driving assembly 4 is used for railway track running.

[0053] Compared with the prior art, this embodiment provides a multi-drive mode vehicle that can cross vertical obstacles, using tires to adapt to flat roads, using crawlers to cross small obstacles, using swing arms to cross large obstacles, and using rail wheels to adapt to railway tracks. When performing emergency rescue missio...

Embodiment 2

[0096] Another specific embodiment of the present invention discloses an obstacle-surmounting method for a multi-drive mode vehicle in complex terrain, using the multi-drive mode vehicle in Embodiment 1, the steps include:

[0097] Step 1: Move to the edge of the platform in the tire driving mode. When the tire 31 on one side of the multi-drive mode vehicle moves to the edge of the platform, it is driven by the track and swing arm drive assembly 2, and the other side is on the platform using the tire Drive assembly 3 drives.

[0098] Such as Figure 4 As shown, when the multi-drive mode vehicle adopts the obstacle-crossing driving mode, the four crawlers 21 are divided into left front crawler, right front crawler, left rear crawler, and right rear crawler according to the forward direction of the multi-drive mode vehicle. The length of the crawler 21 (the distance from the tire 31 to the farthest end of the crawler 21) is 1820mm. Considering the actual influence factors and t...

Abstract

The invention relates to a multi-drive-mode vehicle for complex terrains and an obstacle crossing method of the multi-drive-mode vehicle, belongs to the technical field of road-rail dual-purpose vehicles and obstacle crossing rescue, and solves problems that in the prior art, when the road-rail dual-purpose vehicles are used for rescue, the obstacle crossing capability is poor, rail climbing operation is complex, and the time is long. The vehicle comprises a vehicle main body (1), a tire driving assembly (3), a rail wheel driving assembly (4) and a mechanical foot assembly (5), wherein the tire driving assembly (3), the rail wheel driving assembly (4) and the mechanical foot assembly (2) are all arranged on the vehicle main body; the tire driving assembly (3) is used for running on a flat road surface, the rail wheel driving assembly (4) is used for running on a railway rail, and the mechanical foot assembly (5) is used for cross-country or obstacle crossing. When an emergency rescue task is executed, a better driving mode can be selected according to different conditions, so the time cost for arriving at an accident site is saved, and rescue efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of road-rail dual-purpose vehicles and obstacle-surpassing rescue, in particular to a multi-drive mode vehicle for complex terrain and an obstacle-surmounting method thereof. Background technique [0002] In recent years, with the development of my country's economy and the acceleration of urbanization, urban traffic has been under unprecedented pressure. In order to alleviate the pressure of urban traffic, underground traffic has developed rapidly. With the development of underground transportation in China, the application scenarios of underground space are becoming more and more complex, such as underground shopping malls, underground pipe corridors and other underground buildings are also growing rapidly. [0003] Because the building structure in the underground space is very complex, the terrain is changeable, and there are too many obstacles, the space size requirements are strict. When disasters suc...
