The use mode of the invention is as follows:
when the railway vehicle normally operates on a single vehicle, the first-stage air guide sleeve and the second-stage air guide sleeve extend out and are in a closed state;
when the train needs to be reconnected to operate, front and rear vehicles need to be connected through a coupler, at the moment, the air guide sleeve drives the pneumatic motor to provide power through an air system of the railway vehicle to control the rotation of the driving connecting rod so as to drive the driving connecting rod, the driven connecting rod, the first-stage air guide sleeve and the second-stage air guide sleeve to form a four-connecting-rod mechanism to move, and therefore the first-stage air guide sleeve and the second-stage air guide sleeve can move in a relative and contraction mode. The air guide sleeve drives the pneumatic motor to provide power through an air system of the railway vehicle to control the rotation of the driving shaft so as to drive the upper and lower rotating arms to rotate to realize the contraction motion of the secondary air guide sleeve. At the moment, the air guide sleeve is in a fully opened state, the front vehicle and the rear vehicle run relatively to each other to bump the hook to lock the car coupler, and the electric devices at the car ends are automatically connected.
Then, an air system of the railway vehicle drives a pneumatic motor to drive a driving shaft to rotate so as to drive the upper and lower rotating arms to rotate so as to realize the extension of the secondary air guide sleeve, so that the half-open state of the air guide sleeve is realized. The air guide hoods of the front and rear vehicles are in a half-open state, the secondary air guide hoods are tightly attached to the vehicle body through the rubber sealing strips, the secondary air guide hoods of the front and rear vehicles are also attached to each other through the sealing strips, and a certain amount of extrusion deformation is allowed among the mutually attached sealing strips, so that the air guide hoods of the front and rear vehicles are tightly attached to each other when the train is in reconnection, and the defects that a large gap exists between the front and rear vehicles near a coupler when the existing railway vehicle is in reconnection, and the aerodynamic performance of the vehicle is influenced due to irregular airflow and serious turbulence near the gap when the train runs at a high speed are overcome. Meanwhile, the car coupler and the car end electric connection device can be effectively protected, the damage to the car end electric connection device caused by the splashing of sundries such as broken stones and the like brought up by a car in the high-speed running process can be avoided, and the adverse effect on the car end electric connection due to rainy and snowy weather can be avoided. In addition, the front and rear vehicle air guide sleeves are tightly attached through the sealing strips during reconnection, and can be used for making up the micro relative displacement between the front and rear vehicles when the reconnection vehicle passes through a curve through mutual extrusion of the sealing strips, so that the curve of the vehicle is ensured to pass through.
Compared with the prior art, the invention has the following advantages:
1. according to the special air guide sleeve for the double-heading motor train unit, the air guide sleeve in a half-open state can greatly reduce the gap between the air guide sleeves of the front and the rear trains during double heading of the two trains, and the aerodynamic performance of the high-speed train is improved;
2. the special air guide sleeve for the multi-connected motor train unit can effectively reduce the occupied space of the air guide sleeve after being contracted, and ensure that the air guide sleeve is arranged in the head outer cover after being opened and cannot interfere with an energy absorption device and an anti-creeper which are arranged in the outer cover at the front end of the head of the motor train unit;
3. the special air guide sleeve for the reconnection motor train unit can wrap and protect the car coupler and the car end electric connection device when a train is reconnected, can effectively avoid damage to the car end electric connection device caused by splashing of sundries such as broken stones and the like brought up by a car in a high-speed running process, and can avoid adverse effects on the car end electric connection due to rainy and snowy weather.
In conclusion, the technical scheme of the invention solves the problems that the speed of the vehicle cannot be improved due to the influence on aerodynamic performance caused by the serious generation of irregular airflow and turbulence caused by overlarge air guide sleeve gap in the prior art; meanwhile, the splashed broken stones and sundries damage the car coupler and the electrical equipment; rain and snow affect the connection of the electric device.
