Description
Technical field
The invention belongs to the connection area between tramway carriage, particularly relate to the locking dress of a kind of collapsible hitch
Put.
Background technology
The collapsible hitch of tramcar is normally at below train operator room, after car end switching mechanism and kuppe
Side.
As it is shown in figure 1, be the schematic diagram of existing collapsible hitch.As it is shown in figure 1, this collapsible hitch include can be mutual
The front tension bar 1 rotated and back stay 2, when train is properly functioning, hitch is in folded state, and by gib head fixing device by it
It is fixed on below car body.Now the U-type groove 21 of back stay 2 produces to front tension bar 1 outside.
As in figure 2 it is shown, be existing collapsible hitch straight configuration schematic diagram.As in figure 2 it is shown, when train need rescue or
During person's heavily through transport battalion, need to open car end kuppe and switching mechanism, folding hitch launched and stretches, making the U-shaped of back stay 2
Groove 21 snaps in front tension bar 1, and the locking stop of front tension bar 1 is embedded in the U-lag 21 of back stay 2 front end, this locking stop
It is arranged in the front tension bar cavity of front tension bar and back stay junction, plays the effect of locking so that hitch carries out even hanging, reach
Rescue or the purpose heavily joined；After folding hitch stretches and puts in place, need to use locking device, by front tension bar and post-tensioning lever lock
Fixed, to ensure that hitch is constantly in the state stretched, in rescue or heavily coupler buffering device is played in through transport and conduct longitudinal direction of car power
Effect.
When being unlocked by above-mentioned straight configuration, artificial pull handle 11, pulling force passes on pulling block 13 by stay cord 12, pulling block 13
Drive bearing pin 14 rotate, locking stop is sheathed on bearing pin 14, bearing pin 14 drive locking stop around the central axis of bearing pin 14,
Thus pull out from U-lag 21.
In order to ensure the safe and reliable of locking device, occur getting loose during preventing from using thus cause hitch using
Journey occurs unexpected folding, generally uses spring to ensure that locking stop is constantly in the state of locking, it is ensured that hitch stretches shape
State, as in figure 2 it is shown, by pulling block 13 and bearing pin 14, be delivered to the pulling force of two locking extension springs in locking stop, locking kept off
Block is locked in the U-lag of back stay.Under this kind of mode, in order to hitch can be maintained at the state of locking of stretching, need certain
Spring force, therefore the performance of spring serve key effect.But this kind of structure is arranged at the outside of hitch, no because of spring
Only take up certain space, and the situation that corrosion and damage is even lost has occurred in the impact being easily subject to external environment.
