Description

Diesel locomotive reconnection controller

technical field

The utility model relates to a reconnection controller of an internal combustion locomotive.

Background technique

In order to increase the traction tonnage of the train, more and more diesel locomotives as the traction power adopt the traction structure of double locomotives or even multiple locomotives. Usually, in order to give full play to the adhesive traction of the locomotive, the double locomotives are controlled to run under the same traction.

When the reconnection locomotive group enters the long tunnel, as the first tractor locomotive, it can get sufficient oxygen and necessary cooling air for heat dissipation; but as the following traction locomotive, its working conditions will be greatly reduced; Sufficient oxygen, but no cold air for heat dissipation, because most of the air used for cooling belongs to the exhaust gas emitted by the diesel engine of the first locomotive and the air after heat dissipation, which deteriorates the working conditions of the traction locomotives behind, and in severe cases cause it to malfunction.

In addition, in terms of locomotives, there must be two or more resonance points in the diesel engine main generator set from the lowest speed to the highest speed range. Secondly, auxiliary generators, exciters and cooling fans, etc., all have resonance points in the working range.

Once the locomotive is towed under a certain working condition, once it is at or close to a certain resonance frequency, the vibration of the locomotive will inevitably increase. Long-term operation may cause damage to components, failure of operation, and failure.

Utility model content

The technical problem to be solved by the utility model is to provide a reconnection controller for internal combustion locomotives that can control each locomotive in the reconnection locomotive to run under different traction forces and avoid unit resonance.

In order to solve the above-mentioned technical problems, the reconnection controller of the diesel locomotive of the utility model includes: a first intelligent controller installed in the first locomotive and a first locomotive control cabinet connected to the power input control terminal of the engine of the first locomotive, And the second locomotive control cabinet connected to the power input control end of the second locomotive engine located in the second locomotive; the control signal output end of the first intelligent controller is controlled by the first locomotive control line and the first locomotive control cabinet The signal input ends are connected; the reconnection control signal output end of the first intelligent controller is connected with the reconnection control signal input end of the second locomotive control cabinet through the second locomotive control line.

The above technical solution also includes a third locomotive control cabinet located in the third locomotive; the power output control terminal of the third locomotive control cabinet is connected to the power input control terminal of the engine of the third locomotive; the reconnection of the first intelligent controller The control signal output end is connected with the reconnection control signal input end of the third locomotive control cabinet through the third locomotive control line.

In the above technical solution, the first intelligent controller includes: a central processing unit, a control keyboard connected to the central processing unit, and a display screen connected to the central processing unit.

The utility model has positive effects: (1) when the utility model is in use, the steward controls the first locomotive control cabinet through the first locomotive control line through the first intelligent controller of the first locomotive, so that the first locomotive The engine works under the instruction of the first intelligent controller; at the same time, the flight attendant controls the second locomotive control cabinet of the second locomotive through the first intelligent controller through the second locomotive control line, so that the second locomotive engine is controlled by the first intelligent controller. Work under the instructions; in order to realize the traction of reconnected locomotives with different powers, so as to avoid unit resonance.
