The invention provides an anti-collision device of a tramcar. The device comprises a mounting frame and an energy absorption block; a supporting beam plate is arranged on the side, close to the collision direction, of the mounting frame. The supporting beam plate is connected with the energy absorption block; the energy absorption block is filled with foamed aluminum with the density being below 0.22 g/cm<3>. The mounting frame is connected with the tramcar body, the mounting frame is connected and filled with the foamed aluminum with the density being below 0.22 g/cm<3>, so that the energy absorption block absorbs collision energy and prevents a cab and a passenger room body from being damaged when collision occurs; and when the density of the foamed aluminum is 0.2g/cm<3>-0.22g/cm<3>, ina dynamic collision simulation experiment, the unit mass absorbed energy is 2.74-3.02 kJ/kg; and the collision force of the anti-collision device is smaller than the bearable compression load designed for the tramcar body.

    本发明提供了一种有轨电车防撞装置。包括安装架和吸能块;所述安装架靠近碰撞方向的一侧设有支撑梁板;所述支撑梁板与吸能块连接;所述吸能块的内部填充有密度在0.22g/cm3以下的泡沫铝。本发明通过将安装架与有轨电车车体连接,在安装架上连接填充有密度在0.22g/cm3以下的泡沫铝,使吸能块在发生碰撞时,吸收碰撞能量,避免司机室和客室车体损坏,当泡沫铝的密度为0.2g/cm3~0.22g/cm3时,在动态碰撞模拟实验中,防撞装置单位质量吸收的能量为2.74kJ/kg~3.02kJ/kg,防撞装置的碰撞力小于有轨电车车体设计的能承受的压缩载荷。
