Description

Freight tool for complex road conditions Technical Field The utility model relates to the field of freight tools, in particular to a freight tool for complex road conditions. Background The existing freight tools in China have single functions, for example, a flat car (a round wheel is designed below a cargo carrying flat plate) is only suitable for carrying cargos on a flat road, a stair climbing machine (a crawler type stair climbing structure is adopted below the cargo carrying flat plate) is suitable for carrying cargos on stairs (the stair climbing machine can also be used on the flat road but has a slower speed), so that the existing freight tools have single functions, can only be used for carrying cargos on the flat road, can only be used for climbing stairs, and cannot be suitable for freight transportation in different environments. Disclosure of utility model The utility model mainly aims to solve the problem of single transportation function of a freight tool. In order to solve the above problems, the present utility model provides a cargo transportation tool for complex road conditions, comprising: A cargo bed; Track members mounted at left and right side positions of the bottom of the cargo bed; A rear orienting wheel mounted to the bottom of the cargo bed at a location outboard of the track members; And the front universal wheel is arranged at the bottom of the cargo carrying flat plate and is positioned at the middle position of the two crawler belt parts. In one embodiment, the front universal wheel is rotatably connected to the bottom of the cargo bed via a front axle, and the rear directional wheel is rotatably connected to the bottom of the cargo bed via a rear axle. In one embodiment, the front axle and the rear axle are connected by a connecting rod.
