The invention belongs to the field of transportation tools, and particularly relates to a carrying wheel chain. In production and life, heavy objects need to be carried frequently, and common familiesor small units do not always have tool cars such as forklifts and trailers. Even if the tool cars are available, no way can be found out when the requirement of going upstairs and downstairs is met.The invention aims to provide the carrying wheel chain which can easily carry goods to go upstairs and downstairs in a labor-saving manner, is small and flexible, is easy to store and does not need tobe maintained. For solving the technical problem, the technical scheme adopted by the invention comprises that the wheel chain is formed by mounting row wheels at all sections of connecting shaft endof the chain in a staggered manner. The diameter of the row wheels is larger than the length of a single-section chain and smaller than the length of two-section chains. Whether the wheel chain is dragged on the flat ground or stairs, the row wheels make contact with the ground and stair steps. And the chains are not in contact with the ground and stair steps, sliding friction in hauling is converted into rolling friction, and all-terrain labor-saving transportation is achieved.

    本发明属于运输工具领域,具体涉及一种运载轮链。在生产生活中常常要搬运重物,普通家庭或小型单位并不常备叉车、拖车等工具车。而且即便有工具车,遇到上下楼梯的需求也是一筹莫展。本发明旨在提供一种运载轮链,能轻松省力地搬运货物上下楼梯,而且小巧灵活、易收纳,无需保养。本发明解决其技术问题所采用的技术方案是:轮链是将排轮错位安装在链条的每节连接轴端制成。排轮直径大于单节链条长度而小于两节链条长度。使得轮链不论是在平地还是楼梯上拖动,都是排轮与地面、楼梯台阶接触;而链条不与地面、楼梯台阶接触,将拖运中的滑动摩擦转化为滚动摩擦,实现全地形省力运输。
