Abstract
The utility model relates to a two -wayly prevent separator, including core pin, flat stake pocket round pin, split pin, characterized by: the core pin is cylindrical, has opened a slotted hole respectively on the lateral wall of core pin both ends, and the long central line of two slotted holes is all parallel with the core pin axis, flat stake pocket round pin is L shape, and the slotted hole of one side and core pin matches, and it has the split pin to penetrate the hole just to open on the tip lateral wall of this side, has inserted a flat stake pocket round pin in two slotted holes of core pin respectively, and every flat stake pocket is sold and is all locked on the core pin through the split pin is fixed. Its advantage is: simple structure, the equipment of being convenient for, application safe and reliable, the convenient maintenance are maintained, have strengthened joint strength between railway freight car automobile body and the bogie, have prevented at vehicle application, negotiating curve or when taking place the derailment accident, bogie and automobile body separation, after emergence or the derailment accident of effectively having prevented accident takes place, the emergence of follow -up hidden danger accident.
Description
Technical field
The utility model relates to a kind of two-way separation preventing device, railway goods train bogie technical field.
Background technology
Center pin as the critical component in railway goods train bogie, its Main Function: one be guide car body accurately fall into bogie truck cartridge, car body is connected with bogie truck; Two is in vehicle operation, prevents car body and bogie truck accidental separation.
Current domestic railway goods train bogie center pin is standard universal part, center pin is a cylinder, and directly insert bolster centre hole, bottom is directly located on bolster central supporting gusset, top lead car body drop enters bogie truck truck center plate, directly inserts in the middle of car body body center plate and central sill.Be loosely freely to connect between car body and bogie truck, do not have other to be fixedly connected with, when vehicle is in transport process, especially when vehicle high-speed is by little curve or occur in derailment accident, easily there is bogie truck and car body Isolate Problem, cause train operation accident, time serious, will personal injury be jeopardized.
Abroad in railway goods train bogie and lorry body and the work of bogie truck interconnection technique Improvement in recent years, center pin form comprises column type, pallet plug-in type and suspension ring plug-in type center pin three kinds.
Pallet plug-in type center pin limits by bogie structure, and center pin can not insert bolster belly, and processes pallet in column type center pin bottom.During assembling, pallet is stuck in bolster truck center plate center and strengthens boss, and top is inserted in the middle of car body body center plate and central sill, now, center pin is little compared with column type with bolster insertion, and top is identical with column type, still there is the safe in operation hidden danger that column type center pin exists.
Suspension ring plug-in type center pin is that column type center pin top is increased weldering suspension ring, bottom perforate.Top is by car body sleeper beam center and set one's heart disk hole center and penetrate, and bolster belly is inserted by bolster truck center plate in bottom, inserts cotter pilotage and antitheft spring cotter at bolster areole.This kind of form improves car body and bogie truck Joint strenght and safety in operation to a certain extent, but still there is certain drawback.First this connection mode is unidirectional separation preventing device, this form center pin loads sets one's heart in disk hole, needing boatload truck bolster truck center plate from the top down when falling car, there is dress difficulty, the problems such as examine and replace difficulty is large, especially fall to filling off normal cause center pin touch curved or upkeep operation need to change center pin time, directly cannot change, need to pierce car body, remove body center plate and load floor, center pin place, center pin could be extracted, carry out changing and upkeep operation.
Therefore, above-mentioned three kinds of form core pin units are improving the intensity of lorry body and bogie truck interconnection technique, application safety reliably and to facilitate in repair and maintenance etc. still having some limitations property, performance still can not meet best requirement, is necessary to be improved further this.
Summary of the invention
The purpose of this utility model is the deficiency for existing railway truck center pin, there is provided a kind of structure simple, be convenient to assembling, application safety is reliable and facilitate the two-way separation preventing device of the center pin of repair and maintenance, to strengthen Joint strenght between lorry body and bogie truck, prevent vehicle use, by curve or occur derailment accident time, bogie truck is separated with car body, and after the generation of the accident that effectively prevents an accident or derailment accident occur, follow-up accident risks occurs.
In order to realize this purpose, the utility model provides following technical scheme:
The utility model comprises center pin, flat post latch, spring cotter, it is characterized in that: center pin is cylindrical, and center pin two ends sidewall has a slotted hole, the long line of centers of two slotted holes all with central pin shaft line parallel; Flat post latch is L shape, side is mated with the slotted hole of center pin, and in the end sidewalls of this side, have spring cotter penetrate hole, in two slotted holes of center pin, be inserted with a flat post latch respectively, each flat post latch all by spring cotter fixing and locking on center pin.
The long line of centers of two slotted holes of described center pin on the same line, or mutual dislocation.
The utility model has the advantages that: structure is simple, be convenient to assembling, application safety is reliable, facilitate repair and maintenance, enhance Joint strenght between lorry body and bogie truck, prevent vehicle use, by curve or occur derailment accident time, bogie truck is separated with car body, after effectively preventing the generation of contingency or derailment accident to occur, the generation of follow-up accident risks.
