Non-asbestos wet-rolled automobile drum type brake block and manufacturing method thereof

The invention provides a non-asbestos wet-rolled automobile drum type brake block and a manufacturing method thereof. According to the manufacturing method of the drum type brake block, aluminum silicate, zinc powder, blanc fixe, needle-shaped wollastonite, compound graphite, cellulosic fibers, aramid fibers, steel fibers and phenolic resin are poured into a harrow type mixer to be mixed, liquid resin is added in the mixing process, the mixed materials are pulverized by a pulverizer and then are placed in shade places to be dried for 3-4 hours, the dried materials are then put into a hopper of a roller press to be rolled and then are conveyed into a cutting forming machine, the materials are coated with glue and then are adhered to the shoe of the brake block, conventional outer arc polishing, spraying, mark printing and accessory installation, riveting and packaging are carried out after heat treatment and cooling, and finally the brake block is formed. According to the non-asbestos wet-rolled automobile drum type brake block and the manufacturing method thereof, due to the fact that the liquid resin and the wet-rolling technique are applied, the work environment of workers is greatly improved, energy consumption is greatly reduced, environmental performance is good, and the brake block manufactured with the method is free of heat fading, stable in friction coefficient, good in friction performance, stable in braking, sensitive, reliable, and long in service life.

Ground automatic passing slip phase system for electrified railway based on solid transfer switch

The invention provides a ground automatic passing slip phase system for an electrified railway based on a solid transfer switch. The ground automatic passing slip phase system comprises a solid transfer switch, an over-voltage suppression device, a solid transfer switch loop protecting switch and a locomotive position detection device, wherein the locomotive position detection device is arranged on a steel rail; the over-voltage suppression device is arranged between neutral region contact nets and the steel rail; the solid transfer switch and the solid transfer switch loop protecting switch are communicated with neutral regions of contact nets and the contact nets on two adjacent sides; electric split phase neutral regions in the contact nets are kept electrified constantly by powering on the solid transfer switch, so that an electronic locomotive constantly carries phases A and B of voltage when passing through the contact nets. The ground automatic passing slip phase system has the beneficial effects that by transferring the solid switch, the electronic neutral regions of the contact nets constantly carry voltage of 27.5kV in the system, multi-influence of electric split phase to speeds, carrying capacities and the like of a high speed train and a heavy load electronic locomotive is eliminated, furthermore a series of problems caused by electric split phase can be solved, the carrying capacities of locomotives can be increased greatly, and the working intensity of drivers can be relieved.
