Abstract
The utility model discloses a loading mandrel elastic bearing of a car-body test bed, which is characterized in that a base with a hollow cylinder thereon is fixed on a small rail car; a pre-tightening bolt is fixed on the inner cavity bottom of the hollow cylinder of the base; meanwhile, a spring is arranged in the inner cavity; the hollow cylinder on the base is matched with a groove of a supporting block; the upper end of the pre-tightening bolt penetrates through the supporting block and is pre-tightened on the upper surface of the supporting block. By virtue of an elastic mechanism arranged on the small rail car, the acting force acting on the car by the hang-down displacement in the test process is eliminated; the damage to the car during the test process is avoided; and the service life of the small rail car is greatly prolonged.
Description
Technical field
The utility model relates to elastic bearing mechanism, especially relates to the support mechanism that a kind of car body test stand loads push rod.
Background technique
The vehicle body of railway vehicle test stand will use the loading push rod when doing vertical load test, because the loading push rod is heavier, need support; But in vertical loading; When particularly vertically compressing operating mode, load push rod and not only vertically move, and Vehicular body front loading position there is a downward displacement; Drive the loading push rod and move down, can exert pressure to following supporting carriage causes damage.
The model utility content
The purpose of the utility model provides a kind of yielding support, to eliminate in the process of the test infringement to supporting carriage.
For realizing above-mentioned purpose; The utility model provides a kind of car body test stand to load the push rod yielding support; It is characterized in that: on small rail car, have the base of hollow cylinder above fixing one, the hollow cylinder inner chamber bottom surface of base is fixed with the pretension screw rod, and inner chamber is provided with spring simultaneously; The hollow cylinder above the base and the groove fit of anchor plate, anchor plate is passed at anchor plate upper surface pretension in pretension screw rod upper end.
The utility model is eliminated the displacement of the hanging down active force excessive to dolly that occurs in the process of the test through on small rail car, establishing elastic mechanism, has avoided in the process of the test infringement of dolly has been prolonged the working life of small rail car greatly.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
Embodiment
With reference to accompanying drawing; On small rail car 1, have the base 2 of hollow cylinder above fixing one, the hollow cylinder inner chamber bottom surface of base is fixed with pretension screw rod 3, and inner chamber is provided with spring 4 simultaneously; The groove fit of hollow cylinder above the base and anchor plate 6; Anchor plate is passed at anchor plate upper surface pretension in pretension screw rod upper end, and the pretension screw rod makes spring that certain pretightening force arranged, and pretightening force is larger than and loads the pressure of push rod to anchor plate; Can not guarantee when loading push rod is placed on the anchor plate, keep level.Spring by the precompression of pretension screw rod after, the distance between the last plane of base and the lower plane of anchor plate is greater than and loads push rod downward displacement distance when the compression operating mode, general d gets final product about 30mm.Carry above the anchor plate and load push rod 5.Small rail car can vertically move, and anchor plate can vertically move down.
Claims (1)
