Description
The utility model belongs to the rail vehicles annex, especially the connecting device of train steam brake airduct.
Present railway transportation department widely used train steam brake wind tube connecting device.Basically be to adopt angle cock, angle cock done introduction as the train airduct connecting bridge of China Railway Press in " car brakeing machine " book of publishing in 1984.This angle cock comprises tube sealing connector and packing seal and catch gear, spanner, retaining head, terminal point retaining head and housing, because it uses inconvenient, again the steam brake airduct is connected after promptly the hook between the every joint railway carriage of train need being hung up, lock and make the spanner axis consistent after the butt joint of angle cock tube sealing connector with the airduct axis direction, be just in time to connect at this moment, the numerous rope of manual operation like this, poor reliability, easy destroyed molecule utilization, as the saboteur angle cock is closed and will be jeopardized the safety of train, and the complex structure of this device, cost are also higher.
The utility model improves problems of the prior art, provide a kind of simple in structure, cost is low, and is safe and reliable, easy to use, can bear more atmospheric train steam brake wind tube connecting device.
The utility model is realized by following manner: a kind of train steam brake wind tube connecting device, comprise connecting bridge and fixed installation part, connecting bridge of the present utility model is by being provided with the mounting hole I along the cross-sectional plane left-right symmetric, the housing of II and the plug of upper end thereof and its lower end have the fixedly adaptor union of baffle ring, be enclosed within India rubber tube and snap ring thereof on the adaptor union, be installed in two mounting hole I about housing respectively, end nut in the II and on spring and packing ring, and be arranged on one of them mounting hole I inner washer short sliding cylinder and on the air extractor vent II and the long sliding cylinder that is arranged on another mounting hole II inner washer and installs with the plug homonymy and on air extractor vent I composition, wherein, be provided with the mounting hole I along the cross-sectional plane left-right symmetric, the housing of II, the plug of its upper end can be in mounting hole I position, it also can be position in the mounting hole II, but long sliding cylinder must be installed with the plug homonymy, the part of long sliding cylinder is inserted in the plug and can be slided up and down, and it is long, short sliding cylinder all adopts washer sealing, plug and housing are an integral body, can be whole the manufacturings.Also can separately make then and be fixed together, end nut is connected by screw thread and housing, and seals with the packing ring II.And end nut, spring, packing ring in the mounting hole I, II are general-duties.
Said fixed installation part by cooperates with fixedly baffle ring on the adaptor union of housing lower end installation protect frame, base and on captive nut and bolt form.
The utility model in use, adopting two is used, promptly adopt two train steam brake wind tube connecting devices, two save on the railway carriages or the neck of hook before and after being installed in respectively, adapt the position during hook mutually simultaneously with hook, when the hook phase hook of two joint railway carriages, the plug of above-mentioned two fiery steam brake wind tube connecting devices inserts mutually in the other side's the socket, at this moment spring is compressed, air extractor vent on the long and short sliding cylinder is opened, whole steam brake airduct is connected, in order to the usefulness of emergency brake.
The utility model is compared with prior art, have simple in structure, cost is low, esy to use, safe and reliable, have simultaneously and can bear bigger characteristics such as air pressure.
Fig. 1 is an overall structure scheme drawing of the present utility model.
Fig. 2 is the utility model assembly relation scheme drawing.
Among the figure: 1 long sliding cylinder, 2 plugs, 3 mounting hole I, 4 housings, 5 packing ring I, 6 short sliding cylinders, 7 air extractor vent I, 8 packing rings, 9 springs, 10 end nut, 11 packing ring II, 12 adaptor unions, 13 protect frame, 14 fixedly baffle ring, 15 snap rings, 16 India rubber tubes, 17 spring skeletons, 18 captive nuts, 19 bases, 20 train airducts, 21 bolt of rear end plates, 22 mounting hole II, 23 air extractor vent II.
Most preferred embodiment of the present utility model, as shown in the figure.A kind of train steam brake wind tube connecting device, comprise connecting bridge and fixed installation part, connecting bridge of the present utility model has the fixedly adaptor union 12 of baffle ring 14 by plug 2 and its lower end of housing 4 that is provided with mounting hole I 3 and mounting hole II 22 along the cross-sectional plane left-right symmetric and upper end thereof, be enclosed within India rubber tube 16 and snap ring 15 thereof on the adaptor union 12, be installed in respectively in about 4 two mounting hole I 3 of housing and the mounting hole II 22 end nut 10 and on spring 9 and packing ring 8, and be arranged on mounting hole I 3 inner washers short sliding cylinder 6 and on the air extractor vent II and the long sliding cylinder 1 that is arranged on mounting hole II 22 inner washers and installs with plug 2 homonymies and on air extractor vent I 1 composition, wherein, be provided with the housing 4 of mounting hole I 3 and mounting hole II 22 along the cross-sectional plane left-right symmetric, the plug 2 of its upper end can be the position in mounting hole I 3, also can be in the position of mounting hole II 22, but long sliding cylinder 1 must be installed with plug 2 homonymies, the part of long sliding cylinder 1 is inserted in the plug 2 and can be slided up and down, and it is long, short sliding cylinder 1,6 all adopt packing ring 8 and 5 sealings of close circle I, plug 2 is an integral body with housing 4, can wholely make.Also can separately make then and be fixed together, end nut 10 is connected by screw thread and housing 4, and with packing ring II 11 sealing, and end nut 10, spring 9, packing ring 8 in mounting hole I 3 and the mounting hole II 22 are general-duties, be provided with spring skeleton 17 in the India rubber tube 16 in addition, so not only can roll over but also can compress, and the intensity height, the life-span is long.In a word the utility model be a kind of safe in utilization, reliably, train steam brake wind tube connecting device efficiently.
