Problems solved by technology

If the coupling of the couplers of the two trains is not successful, and the rescuers do not find out, or accidental decoupling occurs during the rescue operation, the rescue train continues to run at this time, which will lead to rescue failure and prolong the rescue time, and the air brake of the faulty train has been stopped. Mitigation will cause the faulty train to have neither the power support of the rescue train nor its own braking force, and it will be in a free state. It is likely that the train will slip and slip, causing danger.

Embodiment Construction

[0010] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0011] Referring to the accompanying drawings, the urban rail train coupling and detachment protection device of this embodiment is provided with a head car relay FCR, a tail car relay RCR, a coupling mode switch RROS, a coupler relay TRCR, and a coupler electrical connector TCC at each end of the train. . The brake control unit BCU, wherein:...

Abstract

The invention discloses a city rail train coupling disconnection protecting device. A coupler electric connector TCC and a coupler relay TRCR are arranged at each end part of the train; a coil of each coupler relay TRCR is connected with a 110V DC power supply through the corresponding coupler electric connector TCC; and contact ports are connected in series in a brake control loop. According to the city rail train coupling disconnection protecting device, the coupling state of the train is judged through the coupler electric connectors TCC and the coupler relays TRCR; when the coupled trains are separated from one another, the coil of each coupler relay is in loss of power, each contact port is disconnected, and the brake control loop generates corresponding protection action, thus the safety of the train is ensured when coupling is disconnected.

Description

technical field [0001] The invention relates to an urban rail train coupling detachment protection device, which belongs to the technical field of urban rail trains. Background technique [0002] During the operation of the urban rail train, if it cannot rely on its own traction to continue running due to various reasons, it needs to rely on the power of the rescue train to drag the faulty train back for maintenance. During rescue, the rescue train first realizes coupler docking with the faulty train, and then relieves the air brake of the faulty train through the rescue train, and the faulty train can be dragged by the rescue train. If the coupling of the couplers of the two trains is not successful, and the rescuers do not find out, or accidental decoupling occurs during the rescue operation, the rescue train continues to run at this time, which will lead to rescue failure and prolong the rescue time, and the air brake of the faulty train has been stopped. Relief will cau...
