Abstract
The utility model relates to a quick automatic bow-lowering device for bow net fault, which can effectively realize bow dropping automatically and quickly. The utility model is characterized in that the existing bow lifting and dropping mechanism adds a sensor and an automatic control system. A coupling head is arranged between a cushion valve and a bow lifting cylinder which are arranged on a vehicle top. The output of the automatic bow dropping control valve is connected with gas-filled type sensors by a pipeline. The gas-filled type sensors are arranged on both sides of a pantograph, both ends of which are provided with a stagger limited block exhaust valve. The automatic bow dropping control valve and the connecting pipeline of a bow frame is made from insulation material polytetrafluoroethene. The utility model can be mainly used for the automatically bow dropping of an electric locomotive.
Description
The utility model relates to the Electromechanical Control technical field, particularly block of bow collector of electric locomotive automatic control technology field.
China's electrified railway is in service, pantograph and catenary fault is more, particularly online fork, locating point sharp radius curve, headspan suspension, segmentation and branch are got along, and take place often because the groove of pantograph pan heel and toe wear formation hangs contact system and locomotive pantograph in high-speed cruising is trained off, overturns, breaks the large tracts of land that causes and draw in the net accident.At present, China's electrified railway existing part locomotive in service is installed dynamic detector for bow net failure (number of patent application: 96117695.4), it mainly relies on stagger sensor and the hard spot shock transducer that is installed on the pantograph, and utilize microcam and monitoring device, monitor the running state of contact system and pantograph in real time, when detecting pantograph and catenary fault, relevant informations such as automatic record trouble point kilometer post are so that in time take measures.Along with the raising of railway operation speed, the locomotive operation safety requirements is improved, only depend on monitoring to pinpoint the problems and can not meet the demands.External existing document " electric traction wall bulletin " 1994.4.P18 and US4413710 have reported a kind of device of falling pantograph according to pressurized air release principle automatically, promptly supply with pressurized air by the pantograph driving device, carbon slide plate and plumbing system by the band gas circuit are controlled special-purpose fast prompt drop bow valve, if contact system damages the carbon slide plate, open standpipe thus, make the clutch release slave cylinder exhaust, fall pantograph.The whole control system is arranged on high-pressure side, and is cumbersome during maintenance, because the carbon skateboard complexity of band gas circuit, price is higher, simultaneously, external pantograph structure and domestic block of bow collector of electric locomotive have bigger difference, promote the use of in the electric locomotive at home.
The purpose of this utility model provides the fast automatic bow device that falls of a kind of pantograph and catenary fault, and when electric locomotive was in operation the generation pantograph and catenary fault, it can realize automatically fast prompt drop bow effectively, thereby avoids the expansion of pantograph and catenary fault and guarantee traffic safety.
The purpose of this utility model can be realized by following technical scheme: the fast automatic bow device that falls of pantograph and catenary fault, mainly be at the existing bow that rises, fall in the bow mechanism and increase sensor and autonomous cruise speed system, by pantograph collector head and shelf thereof, the bow control cock is fallen automatically, connector, electric appliance control box, rising bow cylinder and air delivering pipeline forms, electric appliance control box is screwed in driver's cab, there is one on the electric appliance control box panel and falls the bow switch automatically, do not use when falling the bow device automatically, automatically fall the bow switch and be in off-state, at this moment, the locomotive liter, fall bow mechanism fully with identical originally, be not subjected to fall the control of bow device automatically and influence.Increase a connector in the motorcycle pantograph Pneumatic control circuit and fall the bow control cock automatically, connector is between cushion valve on the locomotive top and liter bow cylinder, the cushion valve mouth is connected with an input of connector, a mouth of connector is connected with an input of falling the bow control cock automatically of roof low voltage side with metal tubes, automatically fall a mouth of bow control cock and connect and be connected to a liter bow cylinder with another input of metal tubes and connector, another output of falling the bow control cock automatically is connected with the inflatable sensor with the spacing blow off valve of shelf superelevation with pipeline, and another that falls the bow control cock automatically imported with the interior electric appliance control box of car and be connected by four-core connection lead plug.The cushion valve of pressurized air in the car on electropneumatic valve and pipeline and roof, connector, fall the bow control cock automatically and bend cylinder and be connected with rising, the inflatable sensor is located at the pantograph both sides, two ends are provided with the spacing blow off valve of stagger, and the spacing blow off valve of superelevation is located on the shelf.Pantograph and catenary fault takes place in the locomotive operation process, as inflate sensor interrupted, worn out etc., perhaps contact wire is streaked from the spacing blow off valve of stagger, open spacing blow off valve, perhaps pantograph rises bow and highly surpasses and spacingly open the spacing blow off valve of superelevation or when seriously being broken, and all will make to fall the bow control cock automatically and move.At first cut off the pressurized air of coming, simultaneously, fall the work of bow control cock automatically, trigger electric appliance control box, control annunciator and cut off main circuit breaker of railway engine by electric appliance control box from connector.Simultaneously, rise the rapid emptying of pressurized air in the bow cylinder, cylinder piston rod moves under the spring force effect backward, and pantograph is fallen, the effect that reaches protection pantograph and contact system and reduce the loss.Automatically fall the connecting line of bow control cock and shelf and make, can effectively solve high and low voltage isolation problem by the insulating material polytetrafluoroethylene.
The utility model effect and advantage compared with prior art is that the inflatable sensor adopts hard; the fragility aluminium; be fixed on the existing various pantograph collector head by mounting screw; do not need locomotive and pantograph frame are transformed and can be installed; its all parts that are installed on roof and the pantograph are all rainproof; sun-proof; corrosion prevention; pneumatic control valve can use in-20 degrees centigrade～+ 80 degrees centigrade scopes; be adapted to China south; the weather of northern area; but automatic guidance cuts off line circuit breaker; response time was less than one second; having increased transfinite protection and pantograph superelevation of stagger protects; more perfect function is stronger to the protectiveness of pantograph and contact system.
