图1为本发明弹性排石器的三视图。Fig. 1 is three views of the elastic stone removal device of the present invention.
图2为本发明实施例弹性排石器装配总图。Fig. 2 is a general assembly diagram of the elastic stone removal device according to the embodiment of the present invention.
具体实施方式 Detailed ways
下面结合附图和实施例对本发明申请作进一步说明。The application of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
结合图1至图2可看出本发明的基本结构和具体实施方式。机车转向架弹性排石器，安装在机车转向架端部上用于排除轨道上的障碍物，具有一基架(1)和弹性排石臂(2)，所述弹性排石臂(2)通过可调固定机构悬挂紧固在基架(1)上；弹性排石臂(2)呈中部弯曲的弹性腔体结构。The basic structure and specific implementation methods of the present invention can be seen in conjunction with Fig. 1 to Fig. 2 . The elastic stone removal device of the locomotive bogie is installed on the end of the locomotive bogie to remove obstacles on the track, and has a base frame (1) and an elastic stone removal arm (2), and the elastic stone removal arm (2) passes through The adjustable fixing mechanism is suspended and fastened on the base frame (1); the elastic rock-discharging arm (2) has an elastic cavity structure with a curved middle part.
在本实施例中，基架与弹性排石臂之间由联接板上螺栓紧固在一起。弹性排石器的结构采用板焊接的箱形结构，以减轻弹性排石器的重量。弹性排石臂通过可调固定机构悬挂紧固在基架上，在本例中，可调固定机构为多孔位螺栓联结，弹性排石臂上设置有联接板(4)，基架对应设置有上联接板(3)，联接板上共有6个M24的螺栓孔，在使用中只需要紧固四个螺栓就能满足强度要求，剩余螺栓孔主要方便调整排石器距离轨面的高度。In this embodiment, the base frame and the elastic rock removal arm are fastened together by bolts on the connecting plate. The structure of the elastic stone ejector adopts a plate-welded box structure to reduce the weight of the elastic stone ejector. The elastic rock-discharging arm is suspended and fastened on the base frame through an adjustable fixing mechanism. In this example, the adjustable fixing mechanism is connected by multi-hole bolts. The elastic rock-discharging arm is provided with a connecting plate (4), and the base frame is correspondingly provided with On the connecting plate (3), there are 6 M24 bolt holes on the connecting plate. Only four bolts need to be fastened to meet the strength requirement in use. The remaining bolt holes are mainly convenient for adjusting the height of the stone ejector from the rail surface.
本发明的实际验证以HXD2B机车排石器进行改进为例，在使用中先将弹性排石臂2通过可调固定机构悬挂紧固在一起，基架亦为中孔腔体结构然后将排石器安装在构架上。若在使用中弹性排石器发生磨损，可以通过选用联接板上不同的螺栓孔来调节排石器距离轨面的高度，确保弹性排石器底面距钢轨面距离为30mm左右。本发明能很好的解决当前转向架排石器运用过程中经常出现损伤，延长排石器的使用寿命，并且在列车高速运行的条件下，弹性排石器同样能对与障碍物的高速碰撞起到很好的缓冲作用，能满足高速运行条件下对排石器的性能要求。The actual verification of the present invention takes the improvement of the stone ejector of the HXD2B locomotive as an example. In use, the elastic stone ejector arm 2 is suspended and fastened together by the adjustable fixing mechanism. The base frame is also a hollow cavity structure, and then the stone ejector is installed. on the framework. If the elastic stone ejector is worn during use, the height of the stone ejector from the rail surface can be adjusted by selecting different bolt holes on the connecting plate to ensure that the distance between the bottom surface of the elastic stone ejector and the rail surface is about 30mm. The present invention can well solve the damage that often occurs during the operation of the current bogie stone ejector, prolong the service life of the stone ejector, and under the condition of high-speed train operation, the elastic stone ejector can also play a significant role in the high-speed collision with obstacles. Good cushioning effect can meet the performance requirements of the stone ejector under high-speed operating conditions.
