Description

Locking device for automatic wind power butt joint and separation of railway vehicle

Technical Field

The invention relates to the technical field of railway vehicles, in particular to a locking device for automatic wind power butt joint and separation of a railway vehicle.

Background

The train running on the railway is formed by connecting a front locomotive and a rear linked vehicle in series, and when the train is changed from static state to dynamic state or from low-speed running to high-speed running, the locomotive is pulled by a coupler; when the train is changed from dynamic state to static state or from high-speed running to low-speed running, the vehicles drive the basic brake device to act by pressure air, so that the brake shoes are driven to press the rotating wheels. Because the vehicles do not have a pressure air source, pressure air needs to be sequentially filled into the vehicles which are connected to the rear by means of the locomotive at the front part, and the vehicles at the rear part can push the basic brake device to act so as to generate brake force. The pressure air transmission from the locomotive to the rear vehicle is realized by the train hose connected between the vehicles, and the connection point of the train hose is positioned below the coupler at the connection end part of each vehicle.

Therefore, at present, in order to ensure that the train is stopped at normal speed reduction, the train hoses among the trains need to be connected after the train head and the rear vehicle coupler are connected, the train head fills air to the train hoses of the trains through the connected train hoses, the train hoses among the vehicles to be separated need to be separated before the train head and the rear vehicle coupler are separated, and then the coupler is separated.

At present, the separation and connection of the train hoses are manually carried out, and the operation modes of manually separating and connecting the train hoses and opening and closing the cock cause low shunting efficiency and have potential personal and driving safety hazards; meanwhile, the development of automatic detection and automatic control technology for the vehicle is severely restricted because the freight car does not have a power supply and a power supply device, so that a device capable of realizing the automatic wind power butt joint of the railway vehicle is necessarily provided, the locomotive supplies power to the rear coupling vehicle by automatically supplying wind, but because the distance between the locomotive and the vehicle and the distance between the vehicle and the vehicle are changed during the running process of the train, although the locomotive and the vehicle are coupled by the coupler, a gap still exists between the coupler and the coupler after the coupler and the coupler are coupled, the same distance change can be generated along with the change of the distance between the coupler and the coupler after the mechanical butt joint, so that the wind power butt joint bodies arranged in the two mechanical butt joints are separated, the circuit and the wind path are disconnected, the braking and the air exhaust are generated, and the parking are necessarily provided to keep the distance between the two mechanical butt joint bodies unchanged, thereby solving the above problems.

Step 3, when the locomotive mechanical butt joint body 4 completes the locking work of the rear vehicle mechanical butt joint body 4, the third vent hole 706 and the fourth vent hole 722 arranged on the locking air cylinder 701 arranged on the locomotive mechanical butt joint body 4 are communicated, the pressure air entering the locking air cylinder 701 enters the third air pipe 723 through the fourth vent hole 722, enters the second air pressure channel 614 from the third air pipe 723 and enters the inner air cylinder rear chamber 611 from the second air pressure channel 614 through the outer piston 602, so that the inner piston 609 is pushed by the pressure air to compress the spring, the inner piston rod 612 extends to push the wind power butt joint body 5 to move towards the rear vehicle, and the touch plate 510 and the slide bar 511 on the two wind power butt joint bodies 5 are in contact, so that the dust cover 507 is opened, the wind power butt joint body 5 on the locomotive continues to move until the positive electrode 501, the positive electrode 501 and the positive electrode 5 on the locomotive wind power butt joint body 5 on the locomotive, the third air hole 722 and the fourth air hole 722 are communicated with each, The negative electrode 502, the standard sealing ring 505 and the sealing strip 506 are in contact with the rear vehicle, and are pressed against the positive electrode 501, the negative electrode 502 and the valve rod 524 to move backwards, and the sealing strip 506 is compressed. After the valve rods 524 move towards the respective rear chambers 527, the annular convex parts 528 and the sealing rings are separated from the end walls of the rear chambers 527, and communication between the rear chambers 527 and the middle chambers 526 of the respective wind power interfaces 5 of the locomotive and the rear vehicle is realized.

Step 4, after the rear chamber 527 and the middle chamber 526 of the respective wind power butt joint bodies 5 of the locomotive and the rear vehicle are communicated, the pressure air in the train pipe of the locomotive firstly enters the train hose of the rear vehicle after sequentially passing through the train pipe of the locomotive and a train hose, enters a fifth air pipe 619, a third air pressure channel 617, a core rod 616, the hollow part of an inner piston rod 612, an eighth vent hole 629, a rear chamber 527, a middle chamber 526, a middle chamber vent hole 539 and a valve rod 524 of the rear vehicle, the middle chamber vent hole 539, the middle chamber 526, the rear chamber 527, the eighth vent hole 629, the hollow part of the inner piston rod 612, the core rod 616, the third air pressure channel 617 and the fifth air pipe 619, and then enters the train pipe of the rear vehicle, meanwhile, a part of the pressure air enters the delay reservoir rear chamber 533 through the front chamber vent 538, the front chamber 525, the seventh vent 537, the outer duct 535, and the sixth vent 536; the other part enters the time delay reservoir front chamber 532 through the rear chamber 527 and the fifth vent 534. Until the front and rear pressure of the delay reservoir piston 533 is equal to the train pipe pressure.

And 5, when air enters the train pipe of the rear vehicle, the wind path direction is the same as that of the wind path in the step 2, and the difference is that the locomotive in the step 2 is replaced by the vehicle, so that the locking hook 710 of the rear vehicle is matched and locked with the locomotive locking pin 702.

And 6, sequentially butting other subsequent vehicles according to the air path sequence in the step.

The separation steps of the automatic wind power butting and separating device for the two vehicles are as follows:

step 1: the second three-way electromagnetic valve 720 is controlled to be powered off to cut off a passage from the first vent hole 410 to the locking air cylinder 701, and meanwhile, an air passage from the front cavity 704 of the locking air cylinder to the outside is communicated, so that pressure air in the front cavity 704 of the locking air cylinder is exhausted to the atmosphere, the locking piston 703 is pushed by a spring to extend the locking piston rod 709, the locking hook 710 rotates upwards and moves forwards to complete unhooking, and the passage from the fourth vent hole 722 to the fifth vent hole 707 is opened due to the fact that the locking piston rod 709 extends to exhaust pressure air in the rear cavity 611 of the inner air cylinder, the spring pushes the inner piston 609 to move to drive the inner piston rod 612 to retract, and therefore the two mutually butted wind power butting bodies 5 are enabled to respectively realize retraction and separation.

And 2, after the two wind power butt-joint bodies 5 are separated, controlling the first three-way electromagnetic valve 622 to lose power, cutting off the air supply passages from the pressure regulating valve 621 to the fourth air pipe 618 and the second air pipe 721, simultaneously communicating the fourth air pipe 618 and the second air pipe 721 to the external air passage, discharging the pressure air in the rear cavity 604 of the outer air cylinder, pushing the outer piston 602 to move by the spring, driving the inner air cylinder 608 serving as an outer piston rod to retract, thereby driving the butted mechanical butt-joint bodies 4 to be separated, and discharging the pressure air in the train pipe through the valve rod 524 due to the action of the delay air cylinder 529, so that the separated rear vehicle is braked in place, and the vehicle sliding is avoided. And the front separated train pipe connected with the locomotive continuously supplies air to the train pipe because of the locomotive, after the air outlet is closed by the valve rod 524 and the air exhaust is stopped, the air pressure of the train pipe is timely restored to constant pressure, and after the front vehicle foundation brake device is naturally released for a period of time, the second three-way electromagnetic valve 720 loses power to be communicated with the air supply passage from the detection bin 405 to the locking air cylinder 701, and meanwhile, the air passage from the third three-way electromagnetic valve 706 to the outside through the second three-way electromagnetic valve 720 is cut off, so that preparation is prepared for next butt joint. Meanwhile, the wing post 628 of the telescopic device 6 slides downwards along the support post rolling shaft 309, so that the central lines of the front car mechanical butt joint body 4, the rear car mechanical butt joint body 5 and the telescopic device 6 are superposed with the central line of the box body 3, automatic centering is realized, and preparation is also made for next butt joint. And the wind power automatic butt joint and separation device restores the initial state.

Because each vehicle is provided with the storage battery, all the three-way electromagnetic valves and the two-way electromagnetic valves can still be controlled by the controller within a period of time when the wind power automatic butt joint and separation device is separated.
