Abstract
The utility model discloses a kind of for the normotopia frock in railway freight-car coupler fitting process, belong to railway freight-car coupler assembly technique field.Comprise coupler body, hook tongue, latch-locking, knuckle pivot pin, hook tongue push away iron and car coupler knuckle lock; Described coupler body left side be opening outwardly, in establish the cavity of boss, described hook tongue by knuckle pivot pin and coupler body hinged, described latch-locking, car coupler knuckle lock, hook tongue push away iron and are arranged in coupler body cavity, described car coupler knuckle lock can along the boss vertical motion in coupler body cavity, the bottom surface that described hook tongue pushes away iron is provided with rotating shaft, described rotating shaft to be hinged in coupler body cavity in spacing hole down, also comprises normotopia chock, installs normotopia chock in the space between car coupler knuckle lock and coupler body.Normotopia chock of the present utility model is inverted in switching process at hitch can prevent car coupler knuckle lock play, prevents hook tongue from pushing away iron distortion, reduces the fault rate of coupler and draft gear maintenance, can control effectively to hitch quality.
Description
Technical field
The utility model relates to railway freight-car coupler assembly technique field.
Background technology
In the coupler and draft gear assembling process of railway truck, whole hitch needs to be inverted, car coupler knuckle lock is arranged on also can along the boss vertical motion of cavity inside in coupler body internal cavities, the rotating shaft that its bottom surface is crossed by Gou Shetui Tie Tong is hinged in coupler body internal cavities spacing hole down, in coupler and draft gear transport and inversion switching process, car coupler knuckle lock can produce upper and lower play, the hook tongue of car coupler knuckle lock bottom can be caused when shifting amount is larger to push away iron deviate from, this phenomenon very easily causes hook tongue to push away iron clamping stagnation in coupling of vehicles process, thus cause hook tongue to push away iron producing stretching distortion.It is cause the potential safety hazard in vehicular transport process that hook tongue pushes away the stretching distortion of iron, in Railway Freight Car Repair process, this fault rate proportion is higher, for reducing fault rate, must before the whole hitch of upset, in the cavity of hitch inside, arrange frock, block car coupler knuckle lock and prevent its upper and lower play, guarantee next process normally carries out, take out this frock after the assembling of hitch completes, thus ensure the assembly quality of hitch.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of for the normotopia frock in railway freight-car coupler fitting process, has structure simple, easy to operate, effectively can prevent car coupler knuckle lock play, prevents hook tongue from pushing away the feature of iron distortion.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of for the normotopia frock in railway freight-car coupler fitting process, comprises coupler body, hook tongue, latch-locking, knuckle pivot pin, hook tongue push away iron and car coupler knuckle lock; Described coupler body left side is opening establishes boss cavity outwardly, described hook tongue by knuckle pivot pin and coupler body hinged, described latch-locking, car coupler knuckle lock, hook tongue push away iron and are arranged in coupler body cavity, described car coupler knuckle lock can along the boss vertical motion in coupler body cavity, the bottom surface that described hook tongue pushes away iron is provided with rotating shaft, described rotating shaft to be hinged in coupler body cavity in spacing hole down, also comprises normotopia chock, installs normotopia chock in the space between car coupler knuckle lock and coupler body.
To the further improvement that the utility model does be: described normotopia chock is the sleeve of square-section, the lateral surface of described sleeve is provided with the boss suitable with the external surface of car coupler knuckle lock, and described boss is stuck on the shoulder of car coupler knuckle lock protrusion.Described normotopia chock is rubber or plastic injection piece.
The beneficial effect adopting technique scheme to produce is: the simple volume of normotopia chock structure of the present utility model is little, install or take out all convenient and swift, be inverted in switching process at hitch and can prevent car coupler knuckle lock play, prevent hook tongue from pushing away iron distortion, secure the position that hook tongue pushes away the relative hitch of iron rotating shaft, avoid hook tongue and push away that iron is deviate from, the phenomenon of malreduction, reduce the fault rate of coupler and draft gear maintenance, can control effectively to hitch quality.Chock before using often monthly have a lot ofly push away the stretching fault of iron, after chock uses, fault rate significantly reduces.
