Abstract
The present invention relates to a rail brake for classification station, which is composed of braking rails, hinges, oil cylinder and its control box, pressurizing box, pressure-free oil tank, and high-pressure small gear pump. The internally pushed braking friction, hinge-type fixing and returning oil by compressed air are used for full releasing. Its advantages are simple structure, less energy consumption and easy installation and maintenance.
Description
The present invention is a kind of brake equipment that is used for marshaling yard.
After this stopping device is arranged on marshalling station's hump, first retarder location, alleviation retarder location and litz wire afterbody, the vehicle or the car team of slide are put in marshalling at a high speed to slow down or to stop, existing first retarder location and alleviation retarder location adopt pressurized air jaw type friction braking mode, its weak point is great in constructing amount, the cost height needs a large amount of external energies, and the pressurized air discharging produces very strong noise; And marshalling station's afterbody adopts the skate braking more, and the inefficiency safety factor is low.Have and adopt spring to press braking rail and the method alleviated with hydraulic ram, because of braking and alleviation are two covering devices, the cost height, and need to alleviate power; Braking of the Purely mechanical of employing and alleviation are arranged again, because of its car team collision frequency is big, inevitable serious wear, the life-span reduces; Z L91109811.9 stopping device, because of its clamp type structure, and oil cylinder is between two sleepers, and the installation site is narrow, and causes soft spots of road bed, unfavorable maintenance.Though energy-conservation automatic control can be good, oil cylinder still has the pressure in the fuel tank when alleviating, and does not reach fully and alleviates, and car team is pulled out and is obstructed, and especially locomotive is worn.
The present invention adopts a kind of simple in structure, and installation and maintenance are convenient, and only needs a small amount of energy, can reach the stopping device of alleviating fully.
This drg is by braking rail, hinge, oil cylinder, control box pressurized reservoir and apiezon oil case, compositions such as little high-pressure gear pump.
Braking rail has two, is installed on inboard, stock rail top symmetrically, and two rail lateral surfaces distance is slightly larger than train wheel to wheel rim lateral surface distance.Braking rail is installed on the hinge, and hinge is fixed on the stock rail.Linked to each other by the oil cylinder two ends between two hinges, oil cylinder links to each other with the apiezon oil case with pressure-oil tank by oil circuit.
Its principle of work is: when being in braking mode, electronic two-position three-way valve is in oil supply oil supply cylinder position in the control box, and because of being filled with nitrogen in the fuel tank and pressure being arranged, the oil in the fuel tank is pressed in four (or five) oil cylinders automatically, and gives locking by check valve.When vehicle bangs into braking rail, because braking rail is slightly wider than wheelspan, cause wheel inwardly to push braking rail, and braking rail squeezed fluid compressing cylinder.And hydraulic oil is because of the check valve locking, so produces very big positive pressure between braking rail and the wheel, causes very big friction force, makes the bigger vehicle of inertia, consumes a large amount of kinetic energy, up to stopping.
During relieved state, electronic two-position three-way valve is in the release position, and the hydraulic oil in its oil cylinder can spray into the apiezon oil case immediately because of glancing impact produces very high pressure.Pressure reduces to zero rapidly in the oil cylinder, and makes braking rail be in relieved state.And hydraulic oil reaches a constant volume in the apiezon oil case after, start little high-pressure gear pump immediately by induction installation, make this partly hydraulic oil be pressed in the pressurized reservoir, in order to next circulation.
Further specify below in conjunction with accompanying drawing.
Description of drawings:
Fig. 1 is inner bearing type stopping device braking principle figure
Fig. 2 is that stopping device is overlooked erection plan
Fig. 3 is a stopping device hinge type fixed sturcture erection plan
Fig. 4 is a stopping device oil circuit control chart
Embodiment: braking rail 1 is in the inboard, top of stock rail 2, and two braking rail lateral surfaces distance is slightly larger than the distance of the right wheel rim lateral surface of vehicle wheel, and the braking rail below is connected in stock rail 2 times with hinge 4, and the inboard links to each other with oil cylinder 3.Oil cylinder joins by electronic two position three-way valve 5 in working connection and the control box.Under braking mode, the other two ends of electronic two position three-way valve: an end of connecting working connection is connected on the pressurized reservoir 6 by check valve, and the other end is in closed state.Have two loops to seal simultaneously this moment: one is to get back in the pressurized reservoir by check valve, and one is to be connected on the apiezon oil case 8.When relieved state, the situation at the other two ends of electronic two position three-way valve is: pressurized reservoir 6 fuel-displaced ends are in closed state, and working connection and apiezon oil case 8 are connected.High pressure oil in the oil cylinder is spurted into rapidly in the apiezon oil case 8.Another loop is owing to the pressure that has in the pressure-oil tank 6, have only a small amount of hydraulic oil to get back to the pressurized reservoir from this loop, a large amount of hydraulic oil all is injected in the apiezon oil case 8 when liquid level reach a certain height, start little high-pressure gear pump 7 by control setup, the oil in the pneumatics fuel tank is pumped in the pressurized reservoir 6 once more.In order to next circulation.
Claims (3)
1, the inner bearing type hinge connects stopping at release device fully, has braking rail, hinge, oil cylinder, control box and pressurized reservoir and apiezon oil case, and compositions such as little high-pressure gear pump is characterized in that braking rail is connected with hinge, oil cylinder, adopts the inner support drag friction; Electronic two position three-way valve is connected in oil cylinder and the control box, in addition two-way: the check valve of leading up to is connected with pressurized reservoir, and one the tunnel is connected with the apiezon oil case.Oil cylinder pressurising braking, release are alleviated by electronic two position three-way valve control, and the power resources of its braking are in the extruding that is braked car team.
