The invention relates to the technical field of rail mechanical braking, and discloses anti-heating brake equipment for a track mechanical crane. The anti-heating brake equipment for the track mechanical crane comprises a casing, wherein rollers are movably connected inside the casing; a connecting rod is fixedly connected to the surface of each roller; a spring is fixedly connected inside each connecting rod; an extrusion pipe is movably connected to the surface of each spring; an air plate is fixedly connected to the lower end of each spring; a sliding plate is fixedly connected to the upper end of each spring; a piston rod is fixedly connected to the side, away from the spring, of each sliding plate; and the surface of each piston rod is sleeved and connected with a wave tube. The sliding plates are pushed to slide through upward movement, the wave tubes are further extruded, air is released since the wave tubes are extruded, and the air is exhausted from air openings in the surfaces of the air plates and is blown onto the surface of a rail, so that the effect that the rail surface is subjected to heat radiation while no heat is generated during braking is achieved. The number of the rollers is four, only one group of rollers symmetrical by using the rail as a symmetry center generate a braking effect, and the other group of rollers achieve mutual attraction and clamping effects, so that a phenomenon of insufficient clamping force cannot occur.
本发明涉及轨道机械刹车技术领域,且公开了一种轨道机械吊车用防起热刹车设备,包括壳体,所述壳体的内部活动连接有滚轮,滚轮的表面固定连接有连杆,连杆的内部固定连接有弹簧,弹簧的表面活动连接有挤压管,弹簧的下端固定连接有风板,弹簧的上端固定连接有滑板,滑板远离弹簧的一侧固定连接有活塞杆,活塞杆的表面套接有波管。向上移动推动滑板滑动,进而挤压波管,波管被挤压释放气体,气体从风板表面的风口排出,吹在轨道表面,从而达到了刹车不产热的同时对轨道表进行散热的效果;由于滚轮的数量是四个,且只有以轨道为中心对称的一组滚轮产生制动效果,另一组起到相吸起到夹持的作用,不会出现夹持力不足的现象。
