The invention relates to a top rail braking device which comprises a brake shoe module assembly capable of being in contact with and separated from a rail. The brake shoe module assembly comprises a brake friction shoe, the contact face of the brake friction shoe and a rail is a plane and an arc face, and the other face is provided with a hole, a protrusion and a shoe drill rod limiting hole. The brake shoe holder is provided with a hole and a protrusion which are matched with the brake friction shoe and a shoe drill rod limiting structure, and the shoe drill rod is connected with the brake friction shoe and the brake shoe holder. The plane of the wearing plate is in contact with the brake screw rod, the arc surface of the wearing plate is arranged in the tile support groove, the omega-shaped spring is arranged in the wearing plate groove, the V-shaped spring is arranged in the brake screw rod, the dustproof sleeve cover is connected with the brake tile support through a bolt, and the V-shaped spring and the omega-shaped spring are arranged in the dustproof sleeve cover; and the parking module and the braking module are used for driving a braking lead screw to move so as to realize lifting and falling of a braking friction shoe. The technical problem that a traditional adhesion braking mode cannot provide enough braking force under the complex working conditions such as a large ramp is solved.

    本发明涉及一种顶轨制动装置,包括制动瓦模块组成,其可与轨道接触和分离;制动瓦模块组成包括制动摩擦瓦,其与轨道的接触面为平面和弧面,另一面设有孔、凸起及瓦钎限位孔;制动瓦托上设有与制动摩擦瓦适配的孔和凸起,以及瓦钎限位结构,瓦钎连接制动摩擦瓦和制动瓦托;制动瓦托的另一面设有瓦托凹槽,磨耗板的平面与制动丝杠接触,其圆弧面置于瓦托凹槽内,Ω型弹簧置于磨耗板凹槽内,V型弹簧置于制动丝杠内,防尘套盖通过螺栓与制动瓦托连接,V型弹簧和Ω型弹簧置于防尘套盖内;停放模块和制动模块,驱动制动丝杠移动,实现制动摩擦瓦的抬起和落下。本发明解决了传统黏着制动方式在面对大坡道等复杂工况时无法提供足够制动力的技术问题。
