Abstract
A special lifting appliance for a railway vehicle coupler knuckle belongs to the technical field of railway vehicle lifting equipment, and is used for lifting a plurality of coupler knuckles at one time. The technical scheme is as follows: the special lifting appliance comprises a coupler lifting ring, 4-6 lifting chains and coupler knuckle lifting rings, wherein the upper part of the coupler lifting ring is sheathed on a crown block coupler, the upper end of each lifting chain is connected with the lower part of the coupler lifting ring by a connecting ring, the lower part of each lifting chain is connected with two branched lifting chains, small connecting rings are arranged at the branched lifting chains, the upper ends of the two branched lifting chains and the lower ends of the upper lifting chains are connected by the small connecting rings, the lower end of each branched lifting chain is connected with one coupler knuckle lifting ring, the two coupler knuckle lifting rings at the lower end of the two branched lifting chains are sheathed at two ends of a coupler knuckle pin of one lifted coupler knuckle. According to the railway vehicle coupler knuckle, the structure is simple, the use is convenient, 4-6 coupler knuckles can be lifted simultaneously, also one, two or three coupler knuckles can be lifted, not only the number of the coupler knuckles lifted by a crown block is increased, the lifting time is shortened, and also the overhaul efficiency is improved.
Description
Technical field
The utility model relates to a kind of suspender that lifts railway transportation vehicle coupler hook tongue, belongs to rolling stock hanging device technical field
Background technology
Railway vehicle is the important carried and transported equipment of smelter industrial railway hauling operation.Coupler and draft gear is that the railway vehicle traction connects the important device of hanging, and the hook tongue is the important spare part that bears tractive force of train.Need to decompose maintenance during the maintenance coupler and draft gear, after hitch decomposes, the hook tongue of hitch is because weight is large, out-of-shape need to be used the overhead traveling crane handling, former hook tongue suspender at every turn can only 1 hook tongue of handling, the dismounting of hitch during maintenance, assembling all will be used overhead traveling crane, cause the overhead traveling crane service efficiency low, production time is long.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of coupler of railway car hook tongue special hanger, and this suspender can a plurality of coupler knuckle for car couplers of handling, thereby improves handling efficient.
The technical scheme that solves the problems of the technologies described above is:
A kind of coupler of railway car hook tongue special hanger, its formation comprises hitch suspension ring, chain sling, hook tongue suspension ring, the top of hitch suspension ring is enclosed within on the overhead traveling crane hitch, chain sling has the 4-6 root, the upper end of every chain sling is connected with the bottom of hitch suspension ring, the bottom of every chain sling connects two chain sling branches, and the lower end of each chain sling branch connects hook tongue suspension ring, and two hook tongue suspension ring of two chain sling branch lower ends are enclosed within one by the knuckle pivot pin two ends of hook tongue.
Above-mentioned coupler of railway car hook tongue special hanger, described every chain sling upper end is connected by coupling link with the hitch suspension ring.
Above-mentioned coupler of railway car hook tongue special hanger, the bifurcation of described every chain sling bottom has a little coupling link, and the upper end of two chain sling branches and the lower end of top chain sling are connected by little coupling link.
Above-mentioned coupler of railway car hook tongue special hanger, crossbeam of the bottom of described hitch suspension ring welding, the coupling link of a plurality of chain slings upper ends is enclosed within the hitch suspension ring of crossbeam below.
The beneficial effects of the utility model are:
The utility model hanger structure is simple, and is easy to use, and both 4-6 hook tongues of handling simultaneously also can 1,2 of handlings or 3 hook tongues, have not only increased the quantity of the hook tongue of overhead traveling crane handling, have saved the handling time, have also improved overhaul efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure, mark is as follows: hitch suspension ring 1, coupling link 2, crossbeam 3, chain sling 4, little coupling link 5, chain sling branch 6, hook tongue suspension ring 7, hook tongue 8.
The specific embodiment
The utility model is comprised of hitch suspension ring 1, coupling link 2, crossbeam 3, chain sling 4, little coupling link 5, chain sling branch 6, hook tongue suspension ring 7.
Show in figure, hitch suspension ring 1 are oblate rings, and its top is enclosed within on the overhead traveling crane hitch, and the bottom connects chain sling 4, and chain sling 4 has the 4-6 root, and every chain sling 4 upper ends are connected by coupling link 2 with hitch suspension ring 1.Crossbeam 3 of the bottom of hitch suspension ring 1 welding, the coupling link 2 of a plurality of chain slings 4 upper ends is enclosed within the hitch suspension ring 1 of crossbeam 3 belows, and the effect of crossbeam 3 can prevent that following coupling link 2 from moving up and down and unbalance at hitch suspension ring 1.
Show in figure, the bottom of every chain sling 4 connects two chain sling branches 6, and bifurcation has the upper end of 5, two of little coupling links chain sling branch 6 and the lower end of top chain sling 4 to be connected by little coupling link 5.
Show in figure, two hook tongue suspension ring 7 that the lower end of each chain sling branch 6 connects hook tongue suspension ring 7, two chain sling branch 6 lower ends are enclosed within one by the knuckle pivot pin two ends of hook tongue 8.
Chain sling 4 of the present utility model and chain sling branch 6 are made by the round steel of different size, are formed by identical chain link assembly welding in parallel, and the overall length of chain sling 4 and chain sling branch 6 is 300 ~ 500mm.During handling, first knuckle pivot pin is passed hook tongue hole, make hook tongue 8 placed in the middle, then two hook tongue suspension ring 7 below every cover chain sling 4 are enclosed within simultaneously knuckle pivot pin two ends and get final product.
