The invention discloses a universal type brake head which comprises a mounting plate, a supporting block, a positioning block, a check block, a hexagon socket screw, a brake-shoe drill rod, a brake-shoe drill rod fixing bolt and a self-locking nut. When the universal type brake head is used, brake shoes with different boundary dimensions and interface dimensions can be mounted by replacing the supporting block, the positioning block and the check block; a brake head manufacturer does not need to redesign the brake head, so that the applicability of the brake head is improved, the production cost of the manufacturer is also greatly reduced, and the brake head is an easily-damaged and easily-consumed part and needs to be frequently detached and replaced; in the dismounting and replacing process, a part for positioning the brake shoe can be abraded, installation and positioning of the brake shoe can be affected when the part is abraded to a certain degree, and a brake shoe holder must be replaced; the brake head positioning parts are the supporting blocks, the positioning blocks and the stop blocks, related parts are locally replaced according to needs, the whole brake head does not need to be replaced, and later maintenance is facilitated.
本发明公开了一种通用型闸瓦托,包括安装板、支撑块、定位块、挡块、内六角螺栓、闸瓦钎、闸瓦钎固定螺栓和自锁螺母,本发明在使用时,通过更换支撑块、定位块和挡块,可以安装不同外形尺寸和接口尺寸的闸瓦,不需要闸瓦托生产厂家重新设计闸瓦托,从而提高了闸瓦托的适用性,也极大降低了生产厂家的生产成本,闸瓦是易损易耗件,需要经常拆换;在拆换过程中,对闸瓦进行定位的部件会产生磨损,磨损到一定程度就会影响闸瓦的安装定位,必须对闸瓦托进行更换;而本发明的闸瓦托定位部件为支撑块、定位块和挡块,根据需要对相关部件进行局部更换,不需要对闸瓦托整体进行更换,有利于后期的维护。
