See Fig. 1, the terminal in switch being carried out correct connection according to such as Fig. 1, when train heavily joins, as long as get on corresponding gear by heavily joining change-over swith, just realizing heavily service direction, instruction column of closing the door fare exact connect ion before and after connection train.Structure is simple, easy to operate.
Can find out based on above-described embodiment 1 ~ 3, the some groups of terminals related to directivity control signal can also be comprised in described heavy change-over swith, as front and back pantograph controls train command signal line, left and right train door contract fully interlocking signal line and left and right train door zero-speed signal wire (SW) etc., (these train-lines can arrange according to the difference of train interlock circuit control principle and also can not arrange).Often organize annexation between terminal and each terminal identical with the annexation of arbitrary group of terminal in the annexation and above-mentioned 1 ~ 3 of train electric hook adaptor union coherent signal line terminals;
The change-over circuit realizing directivity train-line when train arbitrary end heavily joins described in the embodiment of the present invention 1 ~ 3, heavily change-over swith is joined by arranging, and when train coupled running, the heavily connection change-over swith held by Ben Chelian extension is placed in conversion position and the heavily connection change-over swith that Ta Chelian extension is held is placed in normal position, or the heavily connection change-over swith company of his car being hung end is placed in conversion position, and the heavily connection change-over swith that end is hung by the company of this car is placed in normal position, realize before and after this car and Ta Che to, open offside door, close offside door, open offside door, close offside door train command signal line when two train arbitrary ends heavily join, ensure these directivity train-line exact connect ions, namely ensure that two current of traffics heavily joined are consistent, switch reveal is consistent.
Below arbitrary end is heavily joined and illustrate: Fig. 2 is that two train arbitrary ends of 4 marshallings heavily join schematic diagram.
Arbitrary end is heavily associated with 4 kinds of situations:
No. 4 cars of the first train and No. 1 car of the second train hang together;
No. 1 car of the first train and No. 4 cars of the second train hang together;
No. 4 cars of the first train and No. 4 cars of the second train hang together;
No. 1 car of the first train and No. 1 car of the second train hang together;
Heavily situation is joined for 4 kinds that mention in Fig. 2, no matter which kind of hangs together, as long as every head car is arranged heavily join change-over swith, hang end change-over swith in the company of this car to get to " conversion position ", hang end change-over swith in the company of his car to get to " normal position ", or get to " conversion position " at company's extension end change-over swith of his car, the company of this car hangs end change-over swith and gets to " normal position ", can realize heavily joining some heavily connection train-lines controlled with directivity of train, as: forward, backward, open offside door, open offside door, close offside door, close the exact connect ions such as offside door and control.
Wherein, the non-non-extension end change-over swith hanging end and his car of heavy Lian Shiben car is all got to " disconnection position ".
Realizing train arbitrary end, heavily to join key point be exactly that will to ensure heavily to join the service direction of train consistent, and namely make the forward signal line of this car be connected with his the backward signal line of car, the backward signal line of this car is connected with his the forward signal line of car.When same train heavily joins, open offside door, open offside door, close offside door, close offside door, these functions such as front and back pantograph controls, chain, the left and right train door zero-speed of left and right train door contract fully also will keep consistency.For realizing this purpose, hanging the heavily connection change-over swith one of sides get to conversion position as long as connected by two trains, it two gets to normal position, just can guarantee heavily to join current of traffic, consistent for train switch reveal with regard to service direction.
Described heavy change-over swith is lead sealing state (in disconnection position) before use.Heavily joining the lead sealing of change-over swith band is to control security consideration, breaks lead sealing operate when needs heavily join conversion.
In addition, front and back pantograph is controlled, left and right train door contract fully chain with the heavily connection conversion and control of left and right train door zero-speed etc. in front of backward control and switch gate control the same, can heavily join in change-over swith the one group of terminal increasing correspondence, its principle is consistent.
The present invention heavily joins change-over swith by arranging, 3 gears are designed to: " disconnection position ", " conversion position ", " normal position " by heavily joining change-over swith, to heavily join some heavily connection train-lines controlled with directivity of train, as: forward, backward, open offside door, open offside door, close offside door, close offside door etc. and carry out circuit conversion by change-over swith, realize train arbitrary end heavily to join (prerequisite is fully automatic electric hook is symmetrical electric hook), this circuit structure is simple, easy to operate, practical reliable, can realize train arbitrary end and heavily join flexibly.
Above embodiment only for illustration of technical scheme of the present invention, is not intended to limit; Although with reference to previous embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
