Technical field

The utility model relates to a kind of railway freight car lancet mechanisms, and in particular to act on lancet under No. 13 hitches of one kind Mechanism.

Background technique

Current rail goods stock generallys use No. 13 hitches, wherein flat car and other for no reason, the vehicle of side wall panel, adopt With No. 13 bottom operation couplers, lifting hook rod is the single pole component being simmered into using round steel, and rear end is that right-angle bending conduct can make to mention The handle of shank rotation, the lower lock that the U-shaped crotch of lifting hook rod front end hooks No. 13 hitches mention, and rear end is installed by lancet rod bearing In the outer downside of car body end carriage, therefore, lifting hook rod during loading and unloading of goods be easy is pounded, occur bending and deformation cannot use, Can not lancet failure.

Summary of the invention

The purpose of this utility model is to provide lancet mechanism is acted under a kind of No. 13 hitches, to solve existing No. 13 vehicles Lancet mechanism is acted under hook to be easy to be pounded during loading and unloading of goods, causes the problem of being unable to normal use.

To achieve the above objectives, the present invention adopts the following technical solutions:

Act on lancet mechanism under a kind of No. 13 hitches, by handle, lifting hook rod, lancet rod bearing, hanging ring, pin shaft, carrier bar, on Connecting rod, lower link, U-shaped rocking bar composition；Lancet rod bearing and hanging ring be fixed on car body end carriage in the following, lifting hook rod respectively with lifting hook rod Support and hanging ring are hinged, and two carrier bars are fixedly connected with the end of lifting hook rod, and upper connecting rod is cut with scissors between two carrier bars with lifting hook rod It connects, pin shaft is fixedly connected with two carrier bar lower ends, and lower link is hinged with pin shaft between two carrier bars, and U-shaped rocking bar passes through lower lock and mentions Shank Kong Houyu upper connecting rod it is hinged, the lower end of U-shaped rocking bar and lower link are hinged；When hitch is in locking position, handle, chain Plate, U-shaped rocking bar naturally droop, and when lancet holds handle, are lifted up lifting hook rod and rotate 90 °, and carrier bar also rotates with it, and to Preceding promotion lower link, it is to rotate in axial direction that lower link, which pushes U-shaped rocking bar or less lock to mention hole, forces lower lock to mention straight to the intracavitary rotation of hook It is opened to lock iron hook tongue is pushed open, Vehicles separation；When coupling of vehicles, hook bolt is pushed back hook chamber, locks iron and is fallen with being self-possessed, lower lock mentions It falls to outside hook chamber, U-shaped rocking bar, carrier bar, handle fall naturally, and lifting hook rod drops back into lancet rod bearing, and hitch forms latch like State keeps coupling of vehicles state.

Above-mentioned handle and lifting hook rod are made of a round steel right-angle bendings.

The utility model has the advantages that

The utility model is mounted below car body end carriage, and the weight that will not be dropped is pounded curved, is avoided because of lifting hook rod quilt Pound it is curved or pound and can not lancet failure；The utility model mechanism kinematic lithe fault-free, dismounting side when inspection and repair of couplers Just.
