Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1 pilot hole, 2 lock bolts, 3 reset spanners, 4 positive stops, 5 working station indicators, 6 lock bolts close indicator lamps, and 7 lock bolts open indicator lamp, 8 alarms, 9 gas source interfaces, 10 air inlet pipelines, 11 door lock housings, 12 cylinders, 13 communication interfaces, 14 reversal valves, 15 outlet pipes, 16 cylinder pistons, 17 controllers, 18 danger buttons, 19 close the door inductor, 20 lock bolt state sensors.
Detailed description of the invention
With embodiment, the utility model is further illustrated below in conjunction with the accompanying drawings: locomotive linkage Pneumatic door lock as shown in fig. 1, lock bolt 2, cylinder 12, reversal valve 14 and controller 17 it is provided with in door lock housing 11, lock bolt is located at the side of door lock housing, tail end is two column latch, it is connected as a single entity in door lock housing, when lock bolt is opened, latch is stretched out by the pilot hole of door lock housing side, embeds latch hole set on doorframe thus is pinned by car door.
Described lock bolt 2 is fixing with the piston rod of cylinder 12 to be connected, as it can be seen, piston rod is provided with a pair of symmetry, cylinder can be made more steadily reliable to the control of lock bolt.The air-path interface of cylinder piston 16 both sides connects with the two-way output port of reversal valve, and the end that controls of reversal valve electrically connects with the interface of controller；The basic demand of reversal valve is a two way selected valve, it is also possible to substituted by other reversal valves meeting condition.Input port is connected to the gas source interface 9 of door lock housing side by pipeline, locomotive the air compressor carried provides pressure gas source.
The gas circuit at cylinder piston rear portion when end obtains electric that controls of reversal valve is connected with pressure port, and piston moves forward, and makes lock bolt stretch out；During reversal valve dead electricity, reversal valve resets, and gas circuit and pressure port that cylinder piston is anterior are connected, and lock bolt is regained.
In order to make lock bolt stable action reliable, cylinder is set side by side with two, the gas circuit of the piston rear portion of two cylinders and piston front portion is respectively communicated with, two cylinder synchronization actions, lock bolt receives thrust or the pulling force of the piston rod of symmetry, even if one of them cylinder action is ineffective, the equally execution of another cylinder, thus improve Reliability of Microprocessor.
Lock bolt protruding side at door lock housing 11 is provided with inductor 19 of closing the door, and inductor 19 of closing the door can use proximity switch, judges the enabling of car door by the proximity state of detection doorframe or closes door state.The side of lock bolt is provided with lock bolt state sensor 20, lock bolt state sensor 20 can use photoelectric sensor, by the reflective or position of transmission-type photoelectric sensor detection lock bolt 2, it is judged that stretching out or retracted state of lock bolt, as position feedback, signal is fed back to controller.
Door lock housing 11 is installed with communication interface 13, and communication interface 13 can use multi-core aviation plug；Described inductor 19 of closing the door, lock bolt state sensor 20 and communication interface 13 all electrically connect with the interface of controller, described communication interface is provided with and controls signal of communication line and the power line that equipment electrically connects with higher level, therefore the power supply of controller and reversal valve is provided by communication interface, communication interface additionally provides and controls equipment with higher level and carry out the holding wire of signal exchange, and thus receive higher level control equipment the unification of all car doors is locked a door instruction and door lock instruction, send when the passs door state of front door lock, latched position state and work as front door lock duty.
Described door lock housing 11 is provided with working station indicator 5, lock bolt closedown indicator lamp 6 and the lock bolt electrically connected with control unit interface and opens indicator lamp 7, be respectively used to display working condition, higher level controls lock bolt out code and the lock bolt OPEN that equipment is sent, higher level controls lock bolt out code that equipment sends and lock bolt OPEN is not equivalent to latched position state, pin position state is by closing the door inductor 19 and lock bolt state sensor 20 provides and is sent to higher level and controls equipment, and when car door and the lock bolt state at front door lock place can be visually observed that.
Described door lock housing 11 is provided with the alarm 8 electrically connected with controller 17 interface, for by communication interface signal, described in close the door the logic state exception of inductor 19 and described lock bolt state sensor 20 time send audible alarm.Logic state is abnormal include lock bolt open or close instruct with time delay after lock bolt or door state be not inconsistent.
Described door lock housing 11 is provided with the danger button 18 electrically connected with described controller 17 interface, makes the pneumatic reset of lock bolt for sending the signal of telecommunication to controller.Danger button is generally disposed at the position being difficult to touching, only needs to interrupt when higher level equipment controls using when there is the state of emergency.
The tail end of described lock bolt is fixedly connected with reset spanner 3, and described reset spanner stretches out outside door lock housing 11, and door lock housing 11 is provided with the positive stop 4 limiting reset spanner 3 stroke, for hand-reset latched position.Lock bolt is likely in cylinder or reversal valve fault, or source of the gas temporary occlusion causes lock bolt action not in place, now manually can be turned back by reset spanner, then safeguard gas-operated lock.
Above technical characteristic can combined crosswise use in various embodiments.Obviously, above-mentioned basic controlling logic only can be completed by common control program, and therefore the technical program is not rely on the program technic of the unknown.But the composition of the technical program the most creatively proposes a kind of new door latch structure, this arrangement works is relatively reliable and is suitable for using in current locomotive system.
