Background technology
In order to ensure the safe and reliable operation of passenger train, vehicle, before dispatching from the factory, typically will carry out a series of test, its
Middle bogie frame strength test is a very crucial test, and it plays highly important to the safe and reliable operation of train
Effect.
In bogie frame strength test Fixture Design, the laterally design of loading, longitudinal traction and restraint device is knot
Structure is the most complicated, design difficulty is maximum is also the position the most easily gone wrong in test.Main cause is in each operating mode of strength test,
It is framed in the load that vertical and horizontal bear very big, and limited the space acting on for frock and very little by frame construction, this
Increase great difficulty to the design of frock.Horizontal loading, longitudinal traction and restraint device great majority all adopt each only in the past
Erect meter, that is, take up space and increase the mounting and adjusting difficulty of frock.Loading examination for duplex pull rod central authorities hitch structure framework
Test, due to every kind of framework drawing pull bar seat in the structure shown here and horizontal stopping seat laterally and vertical position size is different, simultaneously
Restricted by two crossbeam distances on framework, before being allowed to, the tool structure of the similar framework of design is widely different, poor universality again.
Utility model content
The purpose of this utility model be provide one kind will laterally load, longitudinal traction and restraint device comprehensive Design integral
Framed intensity assay device, and, Fixture Design is become 5 modules, be the test of similar structures framed intensity laterally load,
The generalization of longitudinal traction and restraint device and modularized design are provided convenience condition.
For achieving the above object, this utility model provide a kind of bogie frame strength test device it is characterised in that：Bag
Include the revolving bed equipped with oscillating bearing, actuator counter-force seat, laterally load the longitudinal direction that actuator, two ends are respectively provided with movable joint
Constraining rod, length-adjustable drawing pull bar and load constraint seat, are loaded constraint seat and are fixedly connected with revolving bed, revolving bed and start
Device counter-force seat is fixed on testing stand floor, laterally loads actuator one end and is connected with actuator counter-force seat, the other end and loading
Horizontal loading seat on constraint seat connects；Longitudinal restraint bar one end is connected with loading the longitudinal restraint seat on constraint seat, the other end
It is connected with the counter-force seat on testing stand.
Described loading constrains horizontal loading seat, the traction that seat includes being welded successively from lower to upper in locating dowel and locating dowel
Draw-bar seat, horizontal stopping seat and longitudinal restraint seat, every group of module is had a style of one's own, and each module is all machined with cylindrical with locating dowel
Circular hole with size.
This utility model will laterally load, longitudinal traction and restraint device comprehensive Design are integral, by two skew symmetries
The horizontal loading actuator of arrangement replaces loading effect, makes loading constrain seat composition and swings around revolving bed, load is passed
It is delivered at horizontal stopping seat, realize the loading to the horizontal backstop of tested framework；By drawing pull bar, longitudinal traction loads are transmitted
To at the traction seat of framework end, realize the loading to tested framework longitudinal traction seat；Pass through longitudinal restraint bar to realize longitudinally about simultaneously
Bundle.And, Fixture Design is become 5 modules, is that the test of similar structures framed intensity laterally loads, longitudinal traction peace treaty is got one's things ready
The generalization put and modularized design are provided convenience condition.
