Embodiment Construction
[0023] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in various ways defined and covered by the claims.
[0024] see figure 1 with figure 2 , a self-powered electric unlocking device for a railway locomotive opening and closing mechanism, wherein the locomotive opening and closing mechanism includes a locking rod 5.1, a locking cylinder 5.2, a rotating arm 5.3, a door leaf and a pneumatic push rod connected with the locking rod.
[0025] When the power supply and air supply of the locomotive are normal, the PLC and other control systems existing in the circuit system control the pneumatic push rod to realize the movement of the pneumatic push rod, thereby realizing the automatic unlocking of the locomotive. The pneumatic push rod drives the lock rod 5.1 to be inserted into the lock cylinder 5.2 to realize door leaf locking; or the pneumatic push rod drives t...

The invention provides a self-powered electric unlocking device of a locomotive switching mechanism. The unlocking device comprises an unlocking mechanism, a reserve power supply and a control box used for indicating the unlocking mechanism to work, and the unlocking mechanism comprises an electromagnetic push rod which is connected to a lock rod of the locomotive switching mechanism and drives the lock rod to be inserted into a lock cylinder or pulls the lock rod from the lock cylinder and a position sensor which is connected to the electromagnetic push rod and is used for sensing the position of a door leaf. In the self-powered electric unlocking device of the locomotive switching mechanism, self-powered design is adopted, pressure maintaining operation of the switching mechanism in the overall process can be achieved, the using reliability of the switching mechanism is improved, and a locomotive can achieve unlocking even during outage; meanwhile, the device is simple in mechanical structure, reduces locomotive installation and matching requirements, is easy to install and use, can lock the work position of the door leaf of the switching mechanism, and can ensure the stability of the switching mechanism even when the locomotive is in normal operation; besides, the device can be completely compatible with the current unlocking mechanism and does not influence the use of the unlocking mechanism, and exerts no influence on original components of the locomotive.
Description
technical field [0001] The invention relates to the field of railway locomotive unlocking, in particular to a self-powered electric unlocking device for a railway locomotive opening and closing mechanism. Background technique [0002] The opening and closing mechanism of the locomotive is installed at the front and rear ends of the locomotive, and is an important part to realize the reconnection of the locomotive. During normal driving, the opening and closing mechanism is in the closed state; when the locomotive is reconnected, the opening and closing mechanism is opened, and the couplers are interconnected to realize the reconnection of the locomotive. In both states, the opening and closing mechanism has a locking mechanism to ensure that the opening and closing mechanism maintains a stable state in any state. [0003] When the opening and closing mechanism needs to change the working state, the first action that should be realized is to unlock. When the power supply an...
