Novel tramcar frog
The novel tramcar frog comprises a frog body, a sliding block and four groove type steel rails fixedly welded to the four ends of the frog body correspondingly, an assembly cavity is formed in the upper end face of the frog body, and the sliding block is movably and adjustably assembled in the assembly cavity; two sets of symmetrically-arranged inverted-V-shaped frog rim grooves are formed in the positions, located on the left side and the right side of the assembling cavity, of the upper end face of the frog body, a first butt-joint rim groove and a second butt-joint rim groove are formed in the upper end face of the sliding block, and the first butt-joint rim groove and the second butt-joint rim groove are in an inverted-V shape. The first butt-joint wheel flange groove and the second butt-joint wheel flange groove are communicated with the corresponding pair of obliquely-corresponding frog wheel flange grooves in the two sets of inverted-V-shaped frog wheel flange grooves, and grooves of the four groove type steel rails are correspondingly communicated with the corresponding frog wheel flange grooves in the two sets of inverted-V-shaped frog wheel flange grooves respectively. The tramcar passing speed can be increased, vibration noise is avoided, and frog center abrasion is reduced.
本发明公开了一种新型有轨电车辙叉，包括辙叉主体、滑动块以及分别与辙叉主体的四个端头焊接固定的四个槽型钢轨，辙叉主体上端面成型有装配腔，滑动块可移动调节地装配于装配腔中，辙叉主体的上端面在位于装配腔的左右两侧成型有两组对称设置的“八”字型辙叉轮缘槽，滑动块的上端面成型有第一对接轮缘槽和第二对接轮缘槽，第一对接轮缘槽和第二对接轮缘槽呈“八”字型，通过调节滑动块的位置，完成第一对接轮缘槽和第二对接轮缘槽与两组“八”字型辙叉轮缘槽中的相应一对斜向对应的辙叉轮缘槽的连通，四个槽型钢轨的槽分别与两组“八”字型辙叉轮缘槽中的相应辙叉轮缘槽对应连通。本发明可提高电车通过速度，避免振动噪声，减小辙叉叉心磨损。
