Abstract

The invention discloses a coupler device for engineering vehicles connected with a semi-permanent traction rod for metro, wherein one end of the coupler device (1) connected with the semi-permanent traction rod (2) is provided with a sleeve (3), and a connecting rod mechanism (4) for positioning the semi-permanent traction rod (2) is provided on the sleeve (3). The utility model has the advantagesthat the engineering vehicle or the highway-railway dual-purpose vehicle can be directly connected with the metro vehicle, and other external forces and other components are not needed to improve theconnecting efficiency and reduce the manufacturing cost. The utility model has the advantages that the engineering vehicle or the highway-railway dual-purpose vehicle can be directly connected with the metro vehicle.

Description

technical field [0001] The invention belongs to the innovative technical field of subway coupler coupling, and relates to the structural design of a coupling coupling device for engineering vehicles. Background technique [0002] In the maintenance process of subway vehicles, the subway vehicles need to be dragged and hauled by engineering vehicles or public-rail vehicles. Since subway vehicles generally use close-fit couplers, one end of each vehicle will be equipped with a semi-permanent tow bar. At present, the subway maintenance line The engineering vehicles on the road generally use the No. 2 coupler or the combination of the No. 13 coupler and the transition coupler to haul the subway vehicles. And when connecting with the transition hook, it is necessary to use the connecting ring to realize the connecting. [0003] Using the transition hook, the transition hook is heavy and often needs to be connected with a crane or forklift, which is time-consuming and labor-inten...
