Abstract
The invention relates to a dual-system hook of railway train, wherein it comprises: a joint hook and hook with connecting pin hole, and two U-shaped chain hooks, while the connections between them are in U-shaped connected via connecting pins, to form the movable joint whose joint hook and chain hook can rotate; based on the hook type, it can rotate to the drawing direction, to connect two systems; the chain hook has simple structure, long service life and high reliability; and the joint hook and chain hook can meet the demands that the track heights at each track are same, and meet the demands of total load as 3000t; and the invention can use the general hook frame and national buffer of 13-th hook, to transmit the drawing force and impact force between vehicles.
Description
(1) technical field: the invention belongs to the rolling stock draw gear.The company that is used between goods train vehicle and vehicle or locomotive and vehicle hangs.Transmit longitudinal force and impulsive force that train operation or shunting service produce.
(2) background technology:
It is the automatic car coupler that meets the North America AAR of railway association standard of representative and the non-automatic hitch that meets the UIC of International Union of Railways standard that European countries are representative, i.e. screw coupling that the hitch that existing rolling stock adopts roughly is divided into the U.S., Canada.Because the screw coupling complicated operation, working strength is big, and the tonnage that can draw is little, and will progressively be eliminated, but this needs a process.The rolling stock of two kinds of completely different coupler systems so just might appear being equipped with on same railway; And newly purchasing vehicle also can only select a kind of in two kinds of coupler systems, thus in same the railway of Xing Chenging two kinds of coupler systems this greatly limited freely organizing into groups of train, restricted giving full play to of transport capacity, needed to develop for this reason and can realize that two kinds of systems connect the hitch of hanging.
Chinese patent ' convertible hitch ' (ZL02281259.8) has proposed a kind ofly can select connection mode according to butt joint vehicle hitch standard difference on same vehicle.This ' convertible hitch ' chain, gib head of adjacent two joint vehicles with the screw coupling device time articulates mutually, and one is used for traction, and another root is standby.But when this structure may occur following problem: i. with the screw coupling device and the coupler centre line height to the top of rail of automatic car coupler produce inconsistent, as: 10. the chain link of chain when chain is longer (16) fixed end inserts coupler body E shape front end upper inner 4. 5., and the chain other end connects extension with the screw coupling gib head that docks car, and two ends line of centers height is variant.During ii. with the screw coupling device, according to UIC 520 standards, the collapse strength of screw coupling only is 850kN, and because 10. the chain link of the fixed end of screw coupling device inserts coupler body E shape front end upper inner 4. 5., with central automatic car coupler coupler body 5. not on same line of centers, the screw coupling device is under traction working condition, and 5. coupler body will produce an additional moment of flexure, makes train traction gross load out of reach 3000t.(being that screw coupling device proper structural limitations reaches the structural limitations that 5. is connected with coupler body).Iii. coupler body afterbody and hook tail frame are connected is shaped as the U-shaped body, and can not match with homemade existing hook tail frame is connected, promptly can not general state crotchet tail frame and corresponding buffers.
(3) summary of the invention:
The double system car coupler of railway vehicle that the present invention proposes has solved the company of above-mentioned existing two kinds of system's hitches in same rolling stock exactly and has hung problem.Its technical scheme is as follows:
Double system car coupler of railway vehicle, comprise joint gib head 1, coupler body 2 and chain hitch 3, it is characterized in that gib head 1 tail end in joint establishes the tail end U type 1.1 that connects pin-and-hole 1.2 that has, coupler body 2 front ends are established the front end U type 2.1 that connects pin-and-hole 2.2 that has, tail end U type 1.1 inserts in the front end U type 2.1, chain hitch 3 one end U type chain links 3.1 are contained in tail end U type 1.1 inboards, and three U type spares connect with connecting pin 4, form the turning joint that joint gib head 1 and chain hitch 3 rotate around connecting pin; Coupler body 2 tail ends match with the hook tail frame 6 of AAR system vehicle and are connected; The other end U type chain link 3.6 of chain hitch 3 matches with UIC system vehicle screw coupling and is connected; Two U type chain links are connected swivel nut respectively and connect with two, the thread that the band handle is established in the centre connects as one, and constitutes chain hitch 3.
Above-mentioned coupler body tail end 2.3 is fixed in hook tail frame 6, and tail end 2.3 is for having the cuboid of vertical adjusting slotted hole, and its shape and size match with the hook tail frame of No. 13 hitches of existing AAR system; And the energy disperser 7 of No. 13 hitches that match is housed behind hook tail frame.
Have on above-mentioned joint gib head 1 and the coupler body 2 and working or treating the locating dowel pin 5 that control position is fixing.
Gib head 1 fifth wheel profile in above-mentioned joint meets AAR 10A standard, and hook tongue, the hook tongue in it pushes away the gauge member among the iron employing GB7709.
The minimum cross section diameter that above-mentioned pull bar 3.3 bears longitudinal traction power is 44.5mm, and the U type chain link cross-sectional plane that bears longitudinal traction power generation tensile stress is 2 * 40 * 40mm; The material extending yield strength is 1350KN, and compression yield strength is 2000KN.
Above-mentioned primary structure member joint gib head 1, coupler body 2 adopt the B level cast steel that meets the AAR standard; U type chain link, connection swivel nut, pull bar can all adopt high strength alloy steel 35CrMnSiA to make.
Beneficial effect of the present invention:
I. gib head 1 fifth wheel profile in joint meets AAR 10A standard, has all functions of automatic car coupler; The U type chain link of chain hitch 3 also matches with the screw coupling gib head; When forwarding joint gib head 1 or chain hitch 3 levels to vehicle towed direction, just can realize and dock articulating of vehicle AAR system and UIC system two system's hitches.Mix energy disperser again and just transmit the vehicle longitudinal force.
Ii. its shape and size of coupler body 2 tail ends can match with the hook tail frame of existing AAR system No. 13 hitches and be connected.Therefore this patent hitch can with homemade No. 13 hitches and homemade energy disperser 7 adapteds that match.
Iii this patent chain hitch 3 is simple in structure, only needs just to finish repertoire with two U type chain links.Both cancelled middle enclosed ring (with exporting draw gear the sixties and comparing), gib head and attaching parts etc.＜(ZL02281259.8) compare with above-mentioned ' convertible hitch ' need be set yet 〉, the dangerous contact stress of having avoided these members to produce thus causes structural damage, thereby improves greatly structural reliability and service life.(the chain hitch when being subjected to tensile load, chain link removes the tension stress influence, also is subjected to directly contacting with chain link and the influence of the relative minimum contact stress of area, and contact stress is excessive and tensile stress not quite also can cause structural failure.)
Vi. this patent chain hitch 3 is simple in structure, and work simplification, manufacturing cost descend.
V. this patent chain hitch 3 structures, size and joint gib head 1 all satisfy when articulating UIC system and AAR system hitch respectively, and coupler centre line is identical everywhere apart from the rail height.
Vi. the selection of this double system car coupler structure and design parameters and material realizes that the traction gross load reaches the requirement of 3000T: as the selection of pull bar and U type chain link cross-sectional plane and material yield limit.
Vii. 3 liang of U types of chain hitch chain interannular is by bearing pin or is threaded, and is flexible hitch therefore, can rotate respectively around X, Y, Z axle respectively, to realize that reaching hitch even hangs the mobile rotation demand that working position and Fei Lian extension is treated working position.
