本发明提供了一种牵引销保护装置,包括保护套,保护套的内部设有夹层,该夹层中填充有绝热材料,保护套可拆卸地套设在牵引销的工作段的外部,该保护套的内部设有容置空间,牵引销的工作段容置在该容置空间中,以隔绝外界的高温。本发明的牵引销保护装置套设在牵引销工作段的外部时,可避免牵引销工作段与镀锌液接触,保证牵引销在车辆镀锌过程中不会受到外界高温的影响,以确保牵引销整体的结构强度,进而保证挂车及牵引车的连接强度。

    The invention provides a traction pin protecting device. The traction pin protecting device comprises a protecting sleeve, wherein an interlayer is arranged in the protecting sleeve and filled with aheat insulating material, the protecting sleeve is detachably arranged outside a work section of a traction pin in a sleeving manner, an accommodating space is formed in the protecting sleeve, and thework section of the traction pin is accommodated in the accommodating space to insulate high temperature of the outside. When the traction pin protecting device is arranged outside the work section of the traction pin in the sleeving manner, the work section of the traction pin can be prevented from making contact with a galvanizing liquid, the traction pin is prevented from being affected by high temperature of the outside in a galvanization process of a vehicle, so that overall structural strength of the traction pin is guaranteed, and connecting strength of a trailer and a towing tractor is guaranteed.
