用于隧道建设的双向牵引半挂车的设计

由于隧道内部空间狭窄,运输管片或砂浆罐的普通半挂运输车在其中无法实现调头行驶,因此设计开发了双向牵引半挂车。该双向牵引半挂车在隧道内不用调头,在前后均可对其进行拖挂,方便施工,满足了工程需要。为了便于推广和应用,对该车主要部件的设计和选用进行了介绍。

Design of a Bi-direction Tracting Semi-trailer Used For Tunnel

A common vehicle could not be turned round in narrow tunnel shield machine when carrying tunnel ductpiece and cement mortar, so we designed and developed a bi-direction tracting semi-trailer. The bi-direction tractiing semi-trailer can be towed in front and rear in tunnel without being turned round, which makes the construction conveniently and meets the requirements of the project. For promotion and application, an introduction was given to the design of main components and selection of important parts in the article. National patent was obtained for the semi-trailer.
