The specific embodiment
Embodiment one
Shown in Fig. 1～6, this kind rolling stock braking air pipe connects automatically separates device, comprises connecing separating device main body 1, box cover 2 and fixing with mount pad 3.
The said forebody cross section of separating device main body 1 that connects is square, and latter half of cross section is circular; Connect the top of separating device body front end face and be provided with levelling projection 11 and levelling groove 12, connect and separate device body front end basifacial and be provided with locator protrusions 13 and detent 131, the two sides and the top and bottom of said levelling projection are all curved surface.Adjacent one another are two connect separate the device main body each other near after; Under the effect of external force; At first through about two levelling projections realize that two connect the preliminary levelling of separating device, be to realize accurately location through locator protrusions again, both progressively close up with the mode that plugs together; They have formed levelling mechanism jointly, are a kind of connected structures of guiding.
Connecing the front part sides of separating the device main body has the latch hook 14 and trip lever 15 of hinged relatively setting respectively, forms auto lock, unlocking structure; Connect separate the device body interior have one with train gas source pipe 18 bonded assembly cavitys 16; Cavity is separated the device body front end and is communicated with the external world through guiding valve 17 connecing; Valve member is in closed condition under the pretension effect of spring; The connection that can realize tracheae is moved in the guiding valve inboard under the effect in external force, has formed the main channel of air feed.There is an annular protrusion gas source pipe 18 port sides; Can separate the movable joint 19 that the device port shape matches with existing connecing through annular snap buckle one; There is an annular slot inboard of said movable joint; Annular protrusion that cooperatively interacts and annular slot have formed annular buckle jointly, and said movable joint can be rotated with respect to gas source pipe; The said rear portion of separating the device main body that connects slidably is nested with in box cover.
Existing the connecing of movable joint and train separated the device flexible pipe in the same side, can separate device and cooperates with existing connecing, when not needing to connect automatically when separating, can walk around the utility model and directly be connected with the existing contactless switch in two compartments, realized manually, the effect of automatic compatibility.
Said box cover comprises the built-in latch hook of first cavity 21 and inner second cavity, 22, the first cavitys 21 for stepped hole 14, trip lever 15 and slide 25.The front end of first cavity has the inclined-plane to close up 23; The first cavity upper side has chute 28; Downside is jagged 29, the spring 26 of slide through state of nature (send on the top be connected moment suffer oppression be in compressive state) conflict on pad 27, pad is conflicted on the ring ladder that connects the rear portion of separating the device main body; Come down to a recoil spring to be installed connecing to separate between device main body and the box cover, form buffer structure; Can cushion the impulsive force from former and later two directions of compartment, the rear portion of said box cover 2 fixedly is nested with in mount pad through nut 32, and movable gap is arranged between the two.
Described auto lock, unlocking structure comprise the middle part and connect separates device main body pivotally attached latch hook and trip lever; There is an inclined-plane 111 at trip lever front end place; One end of said latch hook and trip lever freely is provided with, and the other end becomes the inclined-plane to cooperate with the box cover and through preloading spring 112 pretensions, latch hook and trip lever can be done the opening and closing campaign simultaneously; For ease of overhauling, put at the box that contacts with latch hook and be provided with a jackscrew 113.
Situation a kind of commonly used as valve member; Valve member is a guiding valve 17, just comes the Kai Heguan of by-pass valve control through the linear slide of valve, and this guiding valve 17 comprises valve body and the gasket seal that is installed in the cavity; This valve body is to be made up of diameter less spool and the bigger valve gap of diameter; Whole Cheng Saizhuan, and on spool, be provided with gas channel, the inner end surface of valve gap is connected through spring and connects on the cavity wall of separating the device main body.Through the outer bound pair guiding valve application of force, be two kinds of mode of operations of guiding valve like what represent among Fig. 7 Fig. 8, can effectively improve the keying of valve.
Gas source pipe connects an opening and connects with existing common airduct and separate the rotating movable joint that device matches in addition, connects through movable joint and existing common airduct and separates device and be connected and can realize well connecting effect, can realize the manually operated function.
The utility model through mount pad is fixed on hitch directly over or under (the two selects one of which); When the compartment connected, the projection of anterior automatic levelling part at first contacted, because projection is a ramp structure; Can realize automatic capturing after pegging graft each other; About cooperate the levelling about the inclined-plane is realized, cooperate the inclined-plane to realize levelling up and down up and down, connect under the effect of external force in two compartments then and be one.
Latch hook slips into the other side's snap close position automatically, realizes both lockings, and is as shown in Figure 8.
As shown in Figure 7; In the process of two car separated, after the hitch between the compartment unlocks state, connect the effect that receives a compartment disintegration external force between the device main body of separating; Make the box cover and connect and separate device main body generation displacement; Then make and separate latch hook and the trip lever rear end suffers oppression and Zhang Qi, promote latch hook then and break away from, guiding valve cuts out simultaneously.
As shown in Figure 9, when needs are changed seal ring, at first rotate the jackscrew that box puts; The manual unlocking latch hook firmly upwards promotes two then and connects and separate the device main body, and connecing two of at this moment and separating the device main body is upwards protuberance of turning cylinder with the locator protrusions of bottom; Self-orientation when arriving design angle open certain angle, and hold mode is constant under the effect of contained spring; So that carry out the replacing of seal ring, press down two contactless switch main bodys after replacing finishes and to return to previous status.
Embodiment 2
Be with embodiment 1 difference, the difference of valve member, in this embodiment, valve member is an angle valve, also is rotovalve, the rotation through spool comes opening and closing of by-pass valve control exactly.This angle valve and existing angle cock have similar structure; Angle valve comprises the spool that is installed in the spherical or column in the cavity; This ball valve is rotated operation through valve handle; Have and close and open two states and existing ball-valve structure is similar, spool links into an integrated entity through a rotating shaft and a valve handle.Automatically connect the function of separating for cooperating to accomplish, focus on the shape of valve handle is improved, valve handle is semicircular arc and the downside that is positioned at spool; And be provided with the pull bar that cooperates with relative valve handle on the device body front end face connecing to separate; The end of said pull bar is a bending-like, separates main body when cooperating when two adjacent connecing like this, and the valve handle that can drive arc through the other side's pull bar is rotated; And then can promote and spur spool and reverse, accomplish the connection of gas circuit or close.The valve member of this kind structure can be accomplished the ball of crossing of the Ministry of Railways and test.Except that the described technical characterictic of specification sheets, be the known technology of those skilled in the art.
