The specific embodiment
Embodiment mono-
As shown in Fig. 1～6, this kind of automatic connecting/disconnecting device for braking air ducts of railroad vehicles, comprises connecing and separates device main body 1, box cover 2 and fixing with mount pad 3.
The described forebody cross section that connects solution device main body 1 is square, and latter half of cross section is circular; The top that connects solution device body front end face is provided with levelling projection 11 and levelling groove 12, connects solution device body front end basifacial and is provided with locator protrusions 13 and detent 131, and two sides and the top and bottom of described levelling projection are all curved surface.Adjacent one another are two connect separate device main body mutually near after, under the effect of external force, first realize two by two of left and right levelling projection and connect the preliminary levelling of separating device, to realize accurately location by locator protrusions again, both progressively close up in the mode plugging together, they have formed levelling mechanism jointly, are a kind of connected structures of guiding.
The front part sides that connects solution device main body has latch hook 14 and the trip lever 15 of relatively hinged setting respectively, forms auto lock, unlocking structure; Connect solution device body interior and have a cavity 16 being connected with train gas source pipe 18, cavity is separated device body front end and is communicated with the external world by guiding valve 17 connecing, valve member under the pretension effect of spring in closed condition, when guiding valve inboard movement under the effect in external force can realize the connection of tracheae, form the main channel of air feed.There is an annular protrusion gas source pipe 18 port sides, link and connect one and can separate the movable joint 19 that device port shape matches with existing connecing by annular snap, there is an annular slot inner side of described movable joint, the annular protrusion cooperatively interacting and annular slot have formed annular buckle jointly, and described movable joint can be rotated with respect to gas source pipe; The described rear portion that connects solution device main body is slidably nested with in a box cover.
Existing the connecing of movable joint and train separated device flexible pipe in the same side, can coordinate with the existing solution device that connects, and in the time not needing automatic connecting-disconnecting, can walk around the present invention and directly be connected with the two existing contactless switchs in compartment, realized manual, automatic compatible effect.
Described box cover comprises the first cavity 21 and the inner built-in latch hook 14 of the second cavity 22, the first cavity 21, trip lever 15 and slide 25 for stepped hole.The front end of the first cavity has inclined-plane to close up 23, the first cavity upper side has chute 28, downside jagged 29, the spring 26 of slide by state of nature (send on top be connected moment suffer oppression in compressive state) conflicted on pad 27, pad is conflicted and is being connect on the ring ladder at the rear portion of separating device main body, be in fact a recoil spring to be installed connecing to separate between device main body and box cover, form buffer structure; Can cushion the impulsive force from former and later two directions of compartment, the rear portion of described box cover 2 is fixedly nested with in mount pad by nut 32, and has movable gap between the two.
Described auto lock, unlocking structure comprises latch hook and the trip lever that middle part is hinged with connecing solution device main body, there is an inclined-plane 111 at trip lever front end place, one end of described latch hook and trip lever freely arranges, the other end becomes inclined-plane to coordinate and passes through preloading spring 112 pretensions with box cover, latch hook and trip lever can do opening and closing campaign simultaneously, for ease of maintenance, put and be provided with a jackscrew 113 at the box contacting with latch hook.
As the conventional situation of one of valve member, valve member is a guiding valve 17, namely carry out the Kai Heguan of by-pass valve control by the linear slide of valve, this guiding valve 17 comprises the valve body and the gasket seal that are arranged in cavity, this valve body is that spool and the diameter larger valve gap less by diameter forms, entirety Cheng Saizhuan, and on spool, be provided with gas channel, the inner end surface of valve gap is connected to and is connect on the cavity wall of separating device main body by spring.By the outer bound pair guiding valve application of force, as the two kinds of mode of operations for guiding valve that represent in Fig. 7 Fig. 8, can effectively improve the keying of valve.
Gas source pipe connects opening and connects and separate the rotating movable joint that device matches with existing common airduct in addition, connects solution device be connected and can realize good connection effect by movable joint and existing common airduct, can realize manual function.
The present invention by mount pad is fixed on hitch directly over or under (the two selects one), when compartment connects, first the projection of anterior automatic adjustment part contacts, because projection is ramp structure, after mutually pegging graft, can realize automatic capturing, left and right coordinates inclined-plane to realize the levelling of left and right, coordinates up and down inclined-plane to realize upper and lower levelling, then connects under the effect of external force in two compartments and is integrated.
Latch hook slips into the other side's snap close position automatically, realizes both lockings, as shown in Figure 8.
As shown in Figure 7, in the process of two car separated, when the hitch between compartment unlocks after state, connect the effect that is subject to a compartment disintegration external force between device main body of separating, make box cover and connect solution device main body generation displacement, then make to separate latch hook and trip lever rear end suffers oppression and Zhang Qi, then promote latch hook and depart from, guiding valve cuts out simultaneously.
As shown in Figure 9, in the time that needs are changed seal ring, first the jackscrew that rotating box puts, manual unlocking latch hook, then firmly upwards promotes two and connects solution device main body, now two connect and separate device main body and upwards swell take the locator protrusions of bottom as turning cylinder, while arriving design angle, automatically locate, open certain angle, and hold mode is constant under the effect of contained spring, to carry out the replacing of seal ring, after replacing, press down two contactless switch main bodys and can return to previous status.
Embodiment 2
As shown in Figure 10～Figure 12,
Difference from Example 1 is, the difference of valve member, and in this embodiment, valve member is an angle valve, is also rotovalve, carrys out opening and closing of by-pass valve control exactly by the rotation of spool.This angle valve and existing angle cock have similar structure, angle valve comprises the spool 41 that is arranged on the spherical or column in cavity, this ball valve is rotated operation by valve handle 42, have and close and open two states, similar with existing ball-valve structure, spool 41 links into an integrated entity by rotating shaft and a valve handle.For having coordinated the function of automatic connecting-disconnecting, focus on the shape of valve handle 42 to improve, valve handle 42 is semicircular arc and the downside that is positioned at spool, and on device body front end face, be provided with and the pull bar of relative valve handle cooperation connecing to separate, the end of described pull bar 43 is bending-like, separates main body while coordinating like this when two adjacent connecing, and can drive the valve handle of arc to be rotated by the other side's pull bar, and then can promote and pull spool to reverse, complete the connection of gas circuit or close.The valve member of this kind of structure can complete the ball of crossing of the Ministry of Railways and test.
Except the technical characterictic described in specification sheets, be the known technology of those skilled in the art.
