Description
Technical field
The utility model belongs to the safety device in the train running, particularly a kind of train trailer warning brake controller.
Technical background
At present, the trailer of train is got in touch with red, green penoncel, signal lamp or interphone and engine driver by the driver and conductor, this contact method, in case trailer the driver and conductor pinpoint the problems, when needing when fast stopping-down, get in touch in order to upper type, long driver did not sometimes note and can cause delay the time, caused a serious accident.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provides a kind of by trailer driver and conductor direct control, with the train trailer warning brake controller of the sound and quick brake.
The technical scheme that the utility model technical solution problem is adopted is: a warning brake controller is installed on the control linkage valve of train trailer, it comprises that valve body one end is provided with two fixed screw holes, captive joint with the control linkage valve with screw, be provided with induction opening in the middle of the valve body and be connected with control linkage valve induction opening; Adorn a spool in the valve body chamber versatilely, spool is fixed on the poppet shaft, and the right-hand member head is provided with the hole, the valve body right-hand member is connected with valve body with valve right-hand member cover screw, and the quad seal circle is housed, poppet shaft is passed in intermediate active, adorns a spring on the poppet shaft between valve right end cap and the spool; The valve body left end is equipped with the valve left end cap, and seals with O-ring seals between the valve body, and poppet shaft is passed in intermediate active, and valve body is threaded with hollow hexagon socket head cap screw; Fix loudspeaker with two screws by fixed screw holes on valve body, horn interface is connected on loudspeaker air cavity and the valve body.
The beneficial effects of the utility model are: load onto this controller at the train trailer, in a single day train takes place and when pinpointing the problems, but driver and conductor's direct control controller is in time reported to the police to driver's loudspeaker that ring, and drag immediately, simple in structure, reliable operation, easy to operate, be not subjected to seasonal effect, can avoid all kinds of railway accidents.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing.

Among the figure, the 1-valve body; 2-is the loudspeaker screw hole fixedly; The 3-poppet shaft; The 4-spool; 5-O shape seal ring; The 6-valve pocket; The 7-induction opening; 8-loudspeaker induction opening; 9-quad seal circle; The 10-horn interface; 11-loudspeaker air cavity; The 12-loudspeaker; The 13-fixed screw holes; 14-valve right end cap; 15-valve left end cap; Hexagonal union (screwed)bonnet (UB in the 16-hollow; The 17-spring
The specific embodiment
With reference to accompanying drawing, this controller mainly is made up of vital partss such as valve body 1, spool 4, poppet shaft 3, adorns a spool 4 in valve body 1 chamber versatilely, and spool 4 is captiveed joint with poppet shaft 3, and poppet shaft 3 left ends are provided with the hole, are used for connecting the driver and conductor and handle the connection chain; Be provided with induction opening 7 in the middle of the valve pocket 6, communicate with train trailer control linkage valve; The right-hand member head valve right end cap 14 and the valve body 1 usefulness screw of valve pocket 6 links together and seals with quad seal circle 9, and poppet shaft 3 is passed valve right end cap 14 centers versatilely; Valve pocket 6 left ends are equipped with valve left end cap 15, between valve left end cap 15 and the valve body 1 with an O-ring seals 5 sealing, valve left end cap 15 usefulness are threaded with valve body 1 hollow in hexagonal gland 16 compress, poppet shaft 3 activities pass valve left end cap centre hole; Valve body 1 is provided with two fixedly loudspeaker screw holes, and with the fixing loudspeaker 12 of screw, the loudspeaker air cavity 11 on the loudspeaker 12 is connected with horn interface 10 on the valve body 1; Left end on valve body 1 is provided with two fixed screw holes 13, captives joint with the control linkage valve of adorning on screw and the trailer.
Its working process of the utility model is to realize like this, when the trailer driver and conductor finds to need warning and drag, pulling is fixed on the manipulation chain in the poppet shaft 3 left end holes, making poppet shaft 3 drive spool 4 moves right, spring 17 is compacted, makes its induction opening 7 and loudspeaker induction opening 8 UNICOMs, loudspeaker induction opening 8 and horn interface 10 UNICOMs, gas will enter loudspeaker air cavity 11 like this, and loudspeaker 12 will send the warning sound; Meanwhile, because spool 3 axially moves to right, valve pocket 6 links with induction opening 7, and poppet shaft 3 is transferred to from valve left end cap 15 centre holes, and the gas of induction opening 7 discharges apace, makes train bag lock, has finished drag, has protected the safety of train; Decontrol when handling chain, under the tension force effect of spring 17, spool 4 and poppet shaft 3 set back.
