Embodiment Construction

[0009] The specific implementation manner of the present invention will be described below with reference to the accompanying drawings. Such as figure 1 Shown: there are automatic reconnection connectors M and T of the prior art, the pin A19 of the automatic reconnection connector M is connected to the positive input end of the power supply, and there is a choice between the positive input end of the power supply and the pin A18 After switch K1, pins C12 and C13 are connected, they are connected to pin A12 through selection switch K2, and pin C15 is grounded; pin A29 of automatic reconnection connector T is connected to the positive input end of the power supply, and the positive input end of the power supply is connected to the positive input end of the power supply. There is a selection switch K3 connected between the pins A28, after the pins C22 and C23 are connected, they are connected to the pin A22 through the selection switch K4, and the pin C25 is grounded. The differe...

Abstract

The invention discloses an urban train fixing and reconnecting device for realizing automatic protection. The device is provided with automatic reconnecting linkers M and T; a relay J1 is connected between a contact pin (C16) of the automatic reconnecting linker M and the positive input end of a power supply; a relay J2 is connected between a contact pin (C19) and the ground; a relay J3 is connected between a contact pin (C26) of the automatic reconnecting linker T and the positive input end of the power supply; a relay J4 is connected between a contact pin (C29) and the ground; and normally-closed contacts J1-1, J2-1, J3-1 and J4-1 of the relays J1, J2, J3 and J4 are connected to a train safety loop wire. The device has a simple structure, low cost and easy realization; when a train is fixed and reconnected, the device can carry out automatic monitoring and control on a marshalling form and a reconnecting option switch; when the marshalling form is wrong or the reconnecting option switch is out of place, the safety loop wire cannot be established between the reconnecting trains, so the hidden trouble of accident is eliminated and safe and reliable operation of the train in reconnection is ensured.

Description

Technical field: [0001] The invention designs a fixed and reconnecting device for urban rail trains, in particular, a fixed and reconnecting device for urban rail trains with simple structure, safety and reliability, which can reduce labor intensity and realize automatic protection. Background technique: [0002] At present, in urban rail transit trains, there are two sections with different wiring, one motor car and one trailer marshalling design, and sometimes it needs to be reconnected, that is, the motor car of one train is connected to the trailer of the other train through a fully automatic coupler, and the reconnection method There are two kinds of free reconnection and fixed reconnection. The existing fully automatic coupler is divided into two parts, the mechanical coupler and the electrical connector. When the two trains are linked together, the 82-core automatic reconnection connector installed under the mechanical coupler is docked and the corresponding pin is co...
