Technical Field

The invention relates to the field of railway vehicles, in particular to an automatic uncoupling device for a railway locomotive coupler.

Background

Locomotive and vehicle, vehicle and vehicle rely on the coupling to be connected, and the coupler knuckle in the coupling forms auto-lock after the interconnect, prevents unexpected disconnection between the coupling. The structure and the state of the coupler are shown in figure 1, when the coupler knuckle is lifted, the coupler lock iron can rotate, and the two couplers are separated. The coupler has various models, and the common use of trucks is 13 couplers (for locomotives) and 17 couplers (for vehicles), and the two couplers are mainly different in the structure for unlocking the 'coupler locking iron'. As shown in fig. 1, the No. 13 coupler adopts a lifting hook lifting pin height to link a coupler knuckle to unlock a coupler lock iron. The upper part of the hook lifting pin is connected with the hook lifting pin by adopting a lifting rod structure, and the hook is unlocked by manually lifting the lifting rod. Under normal conditions, the hook is manually picked and hung between the car couplers, a person stands at the car coupler between the two cars, the lifting rod is manually lifted, and the hook lock iron is opened, so that the manual picking and hanging operation is completed.

Fig. 2a and 2b show the unlocking mechanism of the 17 th coupler, which is located at the lower middle part of the coupler and the lifting rod 301 of the 17 th coupler is located at the lower part of the coupler, and the unlocking mechanism of the 17 th coupler is located at a position different from that of the 13 th coupler. The working principle is as follows: the lifting rod 301 is manually operated to rotate to drive the lower lock pin rotating shaft 302 to rotate, the lower lock pin rod 303 and the lower lock pin 304 are linked to enable the lock iron assembly 305 to move upwards, so that the coupler knuckle 306 can be separated from the locking position, and the coupler knuckle 306 rotates along the coupler knuckle pin 307 to complete unlocking.

The above descriptions are all manual operation of the lifting rod to unlock the coupler knuckle of the coupler. For some special working conditions, such as locomotive unmanned driving, dangerous area operation and the like, the coupler remote control picking and hanging operation can be realized by additionally arranging a mechanical device and a remote control device, so that the operating danger of personnel is avoided, the working efficiency is improved, and the labor cost is saved. However, the additional mechanical device and the mechanical structure of the manual lifting rod are in linkage interference to generate mutual influence, namely the prior art and the manual lifting rod cannot exist simultaneously, but in actual use, the manual lifting rod still needs to be reserved.

Therefore, there is a need for an automatic uncoupling device for a locomotive coupler that can solve the problem of the prior art that the linkage interference is generated between an automatic control executing device and a manually operated coupler lifting rod.
