The present invention aims to install combustion axis sensors on wheels of each carriage of the trains; derailing sensors are arranged on the wheels of each carriage; a valve switching state sensor is arranged on an angle valve of each braking wind pipe of each carriage; a braking exhaust electromagnetic valve is arranged on the braking wind pipe segment of each train; wires communicated with a power supply, and the sensors and electromagnetic valves are arranged in a whole train.
Description
The present invention relates to a kind of automatic safe protective device that the train train uses, this device can prevent that the train train is in operation owing to combustion axle, off-line take place or because the train operation accident that human element is closed the vehicle exhaust valve (the industry predicate is referred to as angle cock) of train to be caused that train can't be braked etc. and cause.
The train train be a kind of on rail the transport agent of high-speed motion, can be in its high-speed cruising owing to the combustion axle takes place multiple reason, until the phenomenon of cutting axle, perhaps, produce the wheel derailment phenomenon, even close in the normal vehicle exhaust valve accident that also can make train because of artificial factor in service of vehicle and can't make train braking, all these phenomenons all may cause the grave accident of train overturning.Present stage does not still have and a kind ofly can prevent the device of train because of previous reasons generation grave accident all sidedly.And, will make the raising train operating safety more necessary along with the raising and the tonnage of train running speed increases.
The purpose of this invention is to provide and a kind ofly can when aforementioned unexpected phenomenon takes place train, can guarantee the train automatic train stop, to avoid or to reduce the automatic safety protector for train of causality loss.
Purpose of the present invention realizes by following measure: the Wheel bearing that respectively saves vehicle of train is provided with the combustion axle sensor, each wheel place at each joint vehicle is provided with the derailing sensor, the airduct Angle valve place of respectively braking at each vehicle establishes the valve opening and closing state sensor, establish brake air draft electromagnetic valve in the brake airduct section of each vehicle, in the permutation train, be provided with the electric wire that is communicated with power supply and aforementioned each sensor and electromagnetic valve.Work as train when adopting this device the combustion axle takes place, or off-line, or close Shi Junhui and produce action because of the human element accident knuckle exhaust valve that will brake because of corresponding sensor, the set brake air draft electromagnetic valve of power supply and train brake airduct section is connected and the air draft brake, realize the purpose of the timely autobrake of train, avoid train generation grave accident, or reduce the loss that causes because of accident.
Purpose of the present invention also can realize by following measure:
In train, be provided with a power-polar curve, a positive source line and a lead, wherein positive source line and power supply and be located at train brake electromagnetic valve foremost and connect, be provided with a hand switch of often opening between lead and power supply, and lead is communicated with another brake electromagnetic valve of train extreme end and connects with the power-polar curve, lead also is communicated with the positive source line with the valve opening and closing state sensor of establishing by the Angle valve place, an end that respectively fires axle sensor of train and positive source line are connected, the second set lead of the other end and every joint vehicle is connected, conducting between described second lead and power-polar curve, terminals of the sensor that respectively derails of train and positive source line are connected, another end and the connection of described lead.To be implemented under the different situations, close vehicle knuckle exhaust valve etc., all purpose that can in time brake by described Circuits System to vehicle as firing axle or wheel off-line (i.e. derailing) or accident.
Connect in the present invention and can be provided with news Chinese percussion instrument spare between combustion axle sensor and power-polar curve or/and Lamplight displayer spare, can show the car body position of et out of order when combustion spool phenomenon taking place, so that in time repair to be implemented in.
It is by the outside face two corresponding local insulating barriers of locating to be provided with at the one section conductor that drives mutually with the valve rod of Angle valve that Angle valve of the present invention opens and closes state sensor, and two elastic contact chips are set in the position of the set insulating barrier of described conductor constitute, when exhaust valve is in the open position, described two elastic contact chips contact with set insulating barrier on the described conductor respectively, make sensor be in open-circuit condition; And described elastic contact chip contacts with conductor when exhaust valve is gone to the position of closing, and makes current lead-through, makes device start working and in time brake.
Derailing sensor of the present invention is by being arranged at vehicle wheel to the contact of a pair of mutually not conducting on the bogie side frame be used for connecting in working order the T type contactless switch of described contact and be positioned on the contact lever, is used for the bulge-structure of jack-up T type contactless switch and is used for the hinge that contact lever is fixed on the vehicle is constituted.At off-position, contact lever does not contact with ground or track sleeper.Described contact lever contacts with ground or sleeper when vehicle generation off-line accident, and be fixed in hinge through on the compartment around it, and the bulge-structure on it is separated with T type contactless switch, T type structure falls under its deadweight or the action of the spring on it, with two contact conductings, make device start working and in time brake.
Combustion axle sensor of the present invention is by a pair of contact of not conducting mutually that is arranged on the Wheel bearing, form with the cushion block that constitutes by fusible alloy that is used in working order connecting the T type contactless switch of described contact down and be positioned under the T type contactless switch, the cushion block that fusible alloy wherein constitutes should be positioned at bearing shell or bearing place, and places the contactless switch of T type contactless switch T of following time type structure not contact with described contact at fusible alloy.Combustion axle sensor of the present invention is when vehicle generation hot box accident, because the fusible alloy pad is positioned at bearing shell or bearing place, must be subjected to firing the influence of the heat that is transmitted the axial region position, when axle temperature is higher than the fusing point of fusible alloy, this pad promptly melts, and the contactless switch of T type promptly falls the described contact of conducting, makes device work simultaneously and brakes.The used fusible alloy pad material therefor of the present invention preferably adopts Babbitt matal identical with bush material or that fusing point is lower, or other similar lead-base alloys.
It is the member of being located on the train exhaust duct that is I shape that brake airduct section of the present invention is established brake air draft electromagnetic valve, the valve body of an one horizontal end for matching with set sealing surface in the airduct, another horizontal end is the piston of being located in the cylinder, have a through hole that is communicated with the gentle cylinder of valve body in its vertical end, in this through hole, be provided with the needle-valve that drives with electromagnet.Described this valve is when the device circuit conducting, its electromagnet moves and needle-valve is picked up, make described through hole conducting, the pressurized air that is in the exhaust duct promptly enters in the cylinder through described through hole, promote the piston upward movement simultaneously, valve body is separated with the sealing surface that matches, make the valve complete opening.
Advantage of the present invention is as follows:
1, can be for the train train provide safe automatic safety device, can when taking place, the issuable various accidents of train train in time make Train brake, avoiding the generation of train overturning accident, or reduce the loss that causes because of the off-line accident.
