Abstract
The present invention relates to an automatic connecting and disconnecting device for train couplers, which is an automatic coupler connecting and disconnecting mechanism for replacing a manual coupler lifting device. The automatic connecting and disconnecting device for train couplers is realized by pushing a supporting lever on an original lever by a cylinder cover. When the cylinder cover is lifted, a plug in a coupler is pulled up and the coupler of a train is disconnected. When train carriages are touched each other, a coupler tongue in the coupler rotates for transferring power to a constraint member by a tension spring for dropping the cylinder cover. At this time, the plug drops along with a link for achieving the function of automatically connecting the coupler of the train.

The way of throwing off, pull up latch for solution train gib head is that an end of lever connects latch, by manual operation at the end of train carriage (a 24) installing lever (6).A bigger station has 200 row lorries to carry out decoupling device and hook every day approximately, will untie a row lorry in average seven minutes, and every row lorry has 50 to 60 joint railway carriages again, and every sometimes joint railway carriage all will carry out decoupling device.Also will be in a certain order and step when train carries out decoupling device and disintegrates, at first the pressurized air valve of needs disintegration railway carriage is closed at station to be checked, open connecting compressed-air actuated hose coupling again, after the hose-off between railway carriage, push railway carriage to five by locomotive, six li far away summit district carries out decoupling device latch is pulled up, the workman of decoupling device will finish the railway carriage numbering that decoupling device at first will be found needs decoupling device in the extremely short time, again lever is promoted latch is pulled up, in order not miss the chance that gib head is unsnaped, the workman will run with car, observe the gib head disengagement of two joint railway carriages just can let go always, otherwise just can not safe decoupling device, the gib head of like this plucking not open in addition sometimes or have little time gib head is unsnaped, at this moment want at once discharge signal and machine is passed on a message, notify the driver that train is retracted, again the operation, so not only time-consuming but the effort also dangerous.Though once the someone imagined take automatically-unhooked mode on gib head,, so to realize that automatically-unhooked is difficult in the place of appointment and extremely short time because this body structure of gib head is peculiar and break off relations and will finish.
The objective of the invention is to provide a kind of gib head deassembly device, be used for freeing the large quantities of labours under the extreme busy state, make train realize taking off automatically extension.
The present invention realizes like this, when train is implemented to have indispensable operation now in the appointed place, source of the gas enters in the cylinder of the present invention automatically when closing two joint railway carriage bonded assembly compressed-air hose valves, when surpassing two kilograms of air pressure, pressurized air is just discharged the aperture above close piston flange, its structure is similar to safety-valve, and can make the valve SELF CL in moment, and source of the gas and the source of the gas in the flexible pipe in the cylinder discharged from valve immediately at this moment.When the gas in the cylinder rises piston, there is a spring to promote attaching means the flange on the piston is withstood, make cylinder keep hoisting position.Because the rise of cylinder promotes lever upwards, the latch that is connected on the lever is mentioned, and latch also keeps hoisting position, and this moment, the train gib head was in disconnect mode, can unsnap.When gib head separates, the hook tongue outwards rotates, promote passive shifting block with the active shifting block that is stuck on the pin, be fixed on curve extension spring (as the cable brake on the bicycle) the pulling attaching means on the passive shifting block, because attaching means breaks away from the flange on the piston, piston falls together with cylinder cover, and lever and latch also fall thereupon, and latch drops on the upper surface after the hook tongue outwards rotates at this moment.When railway carriage need connect, two joint railway carriage gib heads were collided and can be connected.
The present invention can not change the railway carriage original structure, only needs at original manual pin pulling out device a cylinder to be installed partly, with the curve extension spring that is connected with cylinder, latch is risen and the whereabouts automatically.The used source of the gas of cylinder utilizes the pressurized air of railway carriage.The point of view of the present invention is not the redesign gib head, so do not influence normal transport, realizes that easily latch automatically rises and falls, and the present invention is simple in structure, both can automatically can be manual yet.Owing to use the railway carriage quantity of railroad vehicle many especially, therefore can save thousands of labour.
