Specific embodiment
Roll brake, including casing, connecting bolt, backing plate, bearing, axle, closure, driven friction, passively passive drum, bulging hydraulic fluid port, active friction plate, disc spring, braking oil duct, piston push rod, liquid pressure Red, liquid pressure Red oil-ins and ventilating component.
Described casing is connected with ground by foundation bolt；Described braking oil duct is connected with brake pump；Described hydraulic cylinder oil inlet is connected with control oil pump；Described passive drum is bolted with casing；Described friction plate both ends of the surface are powdered metallurgical material, are furnished with oil groove above, to facilitate passing through for brake oil, lubrication card；Described axle is machined with axial oil duct and radial direction oil, brake oil is entered between people's active, driven friction disk；High-pressure seal ring is housed between described closure and axle, it is ensured that brake oil does not spill over casing；Described driven friction carries external tooth, is connected with the passive drum with internal tooth；Described active friction plate is machined with internal tooth, and the axle being engaged with active friction plate is machined with external tooth, and active friction plate synchronous rotary is driven when axle rotates, and braking is initial, and driven friction is maximum with active friction plate gap, and driven friction remains static.With the reduction in friction plate gap, braking moment gradually increases until all braking stops.
Described cylinder design is outside casing；Described active friction plate and driven friction interval are installed.When the control oil pressure in hydraulic cylinder increases, piston push rod overcomes the elastic force of disc spring to move right, and the spacing between active and passive friction plate becomes big, and active and passive friction plate is separated, and brake force diminishes until being zero.When the control oil pressure in hydraulic cylinder reduces, due to the elastic restoring force of disc spring, piston push rod is moved to the left, and the spacing between active and passive friction plate diminishes, and brake force gradually increases.
Upper fortune, flat conveying belt type conveyer drum braking：
Start-up course control oil pump starts, and gradually increases control-oil pressure, and piston push rod is moved right, and active and passive friction plate is separated；
Normal operating condition, the oily chestnut of control are opened, and flow pressure reaches maximum, and active and passive friction plate is kept completely separate, and brake pump stops, and does not produce brake force.
Normal brake application process, brake pump are opened, and control-oil pressure is reduced by VFC circuit controls, and the restoring force of spring causes piston push rod to start to be moved to the left, and active and passive friction plate gap diminishes until combining, brake force is maximum；
Brake hard process, brake pump are opened, and by hydraulic speed regulation loop control reduces all the way in addition, piston push rod starts to be moved to the left control-oil pressure, and active and passive friction plate gap diminishes until combining brake force maximum.
Downward belt conveyor drum braking.
It is normal to start, when under ribbon conveyer, fortune is operated in generating state, in heavy load condition, the first not power transmission of motor, material driving conveying belt glide, and conveyer belt drives drum speed gradually to be increased by zero, drive drive system rotation, mair motor power transmission when motor reaches rated speed.Therefore brake control starting loop, the brake force for controlling New Brake by hydraulic control circuit is needed to reduce in proportion on startup.Brake pump is opened, and is full of fluid, while controlling pump opens control-oil pressure being increased by VFC circuit controls between friction plate, piston push rod compression spring slowly moves right, and friction plate is gradually disengaged, and piston push rod reaches low order end, active and passive friction plate is kept completely separate, and brake is declutched.
Orderly shutdown, due to the momentum that the gravity and material of material are downward, easily produces larger mechanical shock energy and damages reducer gear or breaking axis occur, slowly need to brake to conveyer.Brake oil chestnut operates, control-oil pressure is reduced by VFC circuit controls, friction plate slow fixation, viscous braking power slowly increases, and when belt conveying motor speed is decreased to zero, brake oil chestnut stops, oily foxtail millet stops for control, due to disc spring elastic force, active and passive friction plate is tightly fitted, and brake force is maximum；
Brake hard, brake pump are opened, and by hydraulic speed regulation loop control reduces all the way in addition, piston push rod starts to be moved to the left control-oil pressure, and Zhu, Bei Dong Miscellaneous pieces gap diminishes until combining, brake force is maximum；
When downward belt conveyor is in motor-operated running state, start-stop wagon flow journey is with downward belt conveyor drum braking.
