Abstract
The utility model discloses a semi-automatic coupler of an urban rail vehicle. The semi-automatic coupler comprises a coupler head, a hook-shaped plate and an uncoupling rod, wherein a connector is fixed on the coupler head and connected with a control circuit of the urban rail vehicle; and a first stroke switch is fixed in a groove of the hook-shaped plate, a second stroke switch is fixed on one end of the uncoupling rod, and the first stroke switch and the second stroke switch are connected with each other and connected with a human-machine interface of a cab of the urban rail vehicle. The four-contact connector and the stroke switches are arranged on the semi-automatic coupler at the same time, so that the detection on the coupling condition of the semi-automatic coupler can be ensured, and the operation of the vehicle is prevented from being influenced when the coupler detection stroke switches fail to work. The coupler is simple in structure and high in safety.
Description
Technical field
The utility model relates to trolley coach topics on vehicle structure technology field, particularly a kind of city rail vehicle S. A. hitch.
Background technology
The S. A. hitch is mainly used in the connection between city rail vehicle car group unit, generally be arranged in the centre of train, adopt tight lock coupler, the Semi-automatic vehicle hitcher has the autoconnect function on mechanical gentle road, in order to guarantee the safety of train, generally be provided with the hitch control monitor unit on the S. A. hitch.
At present, the S. A. hitch generally adopts the state of travel switch or the single monitoring city rail vehicle S. A. hitch of 4 contact adaptor unions.Travel switch can the direct detection hook lock company hang state, but the travel switch fault may cause surveying and lost efficacy; 4 contact adaptor unions are even hung at gib head the rear S. A. hitch of surveying of fitting and are connected the extension state, but company's extension state of hook lock can not be detected, as uncoupling maloperation etc. not detected.The defective of above two kinds of monitor modes is, when travel switch or 4 contact adaptor unions break down, will directly cause vehicle not move or can not emergency braking.
Summary of the invention
Technical problem to be solved in the utility model is, and is not enough for prior art, and a kind of city rail vehicle S. A. hitch is provided, survey S. A. hitch hook lock connect hang state in, guarantee that hook lock does not affect vehicle operating when surveying the travel switch et out of order.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of city rail vehicle S. A. hitch, comprise hitch gib head, hook plate reconciliation shank, be fixed with adaptor union on described hitch gib head, the described city rail vehicle control circuit of described adaptor union access; Described hook plate groove is fixed with the first travel switch, described solution shank one end is fixed with the second travel switch, described the first travel switch is connected with described the second travel switch, and described the first travel switch and described the second travel switch all access described city rail vehicle driver's cab man-machine interface.
Compared with prior art, the beneficial effect that the utility model has is: the utility model is provided with 4 contact adaptor union and travel switches simultaneously on the S. A. hitch, both can guarantee to survey S. A. hitch hook lock and connect the extension state, can guarantee again that hook lock did not affect vehicle operating when surveying the travel switch et out of order; The utility model is simple in structure, and is safe.
Description of drawings
Fig. 1 is the utility model one embodiment 4 contact adaptor union schematic diagrams;
Fig. 2 is the utility model one embodiment travel switch connection diagram;
Fig. 3 is the utility model one example structure schematic diagram;
Fig. 4 is the utility model one embodiment 4 contact contactless switch arrangement structure figure.
The specific embodiment
As shown in Figure 3, the utility model one embodiment comprises hitch gib head 2, hook plate 3 reconciliation shanks 4, is fixed with 4 contact adaptor unions 1 on described hitch gib head 2, the described 4 contact adaptor unions 1 described city rail vehicle control circuits of access; Described hook plate 3 grooves are fixed with the first stroke switch S 1, described solution shank 4 one ends are fixed with the second travel switch S2, described the first stroke switch S 1 is connected with described the second travel switch S2, and described the first stroke switch S 1 and described the second travel switch S2 all access described city rail vehicle driver's cab man-machine interface.
As shown in Figure 2, travel switch S1 and S2 series winding, its state shows on driver's cab HMI.4 contact adaptor unions are connected to the Train Control circuit, and travel switch does not participate in controlling, only show its state on HMI, so both can survey S. A. hitch hook lock and connect the extension state, can guarantee that again hook lock does not affect the operation of vehicle when surveying the travel switch et out of order.
As shown in Figure 1 and Figure 4,4 contact adaptor unions 1 comprise a pair of movable contact 6 and a pair of fixed contact 5, and movable contact 5 protrudes approximately 10mm of hitch gib head joint face.After gib head connected the extension applying, movable contact and fixed contact were connected and are consisted of the loop, and electric signal is delivered to the Train Control circuit.
Claims (2)
1. a city rail vehicle S. A. hitch, comprise hitch gib head, hook plate reconciliation shank, it is characterized in that, is fixed with adaptor union on described hitch gib head, the described city rail vehicle control circuit of described adaptor union access; Described hook plate groove is fixed with the first travel switch, described solution shank one end is fixed with the second travel switch, described the first travel switch is connected with described the second travel switch, and described the first travel switch and described the second travel switch all access described city rail vehicle driver's cab man-machine interface.
2. city rail vehicle S. A. hitch according to claim 1, it is characterized in that, described adaptor union is 4 contact adaptor unions, and described 4 contact adaptor unions comprise a pair of movable contact and a pair of fixed contact, and described movable contact protrudes described S.
