Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of the vertical force application apparatus of the utility model.
Embodiment
The utility model is expanded on further below in conjunction with the accompanying drawings.
As shown in Figure 1-2, the test device of steel rail fastener longitudinal resistance, including supporting plate 1, horizontal force application apparatus are (in figure
Be not drawn into), vertical force application apparatus and displacement measurement apparatus 2；Rail 3 is placed in the supporting plate 1 and branch is fixed on by fastener 4
On fagging 1；The level force, which puts dress, to be used to apply the horizontal thrust parallel to rail 3 to one end of rail 3；It is described vertically to apply
Power apparatus is used to apply vertical pressure to rail 3；The displacement measurement apparatus 2 is being applied in vertical pressure for determining rail 3
When, the horizontal displacement produced under horizontal thrust.
Further, support frame and the vertical guide rods 5 of Duo Gen are fixed with the supporting plate 1, support frame as described above is by transverse slat 6
Constituted with two pieces of risers 7, the guide rod 5 is located in support frame close to the both sides of riser 7 respectively, and the two ends of guide rod 5 are solid respectively
It is scheduled on transverse slat 6 and supporting plate 1；Vertical force application apparatus is fixedly installed positioned at the side of supporting plate 1 in the transverse slat 6.It should be understood that
That described support frame plays a part of the vertical force application apparatus of support, vertical force application apparatus by apply on the surface of rail 3 to
Under vertical pressure and realize to the application of the load of rail 3.
In addition, stable, balanced in order to ensure to be applied to the vertical pressure on rail, the vertical force application apparatus includes fixing
The oil cylinder 8 on transverse slat 6 is arranged on, the portable plate 9 of the end of oil cylinder 8 is fixedly installed on, is fixedly installed on the pressing plate of the bottom of portable plate 9
10, two STHs of the portable plate 9 are simultaneously set on the guide rod 5 of both sides, so, and guide rod 5 is played to whole vertical force dress
The guide effect put, it is ensured that the pressure of application is vertical force.In order that vertical force application apparatus is more stablized, described guide rod is extremely
It is less 2, more preferable way is, guide rod is 4, the corner of portable plate 9 is slided up and down guide rod 5 is cofree.Institute
State pressing plate 10 to be fixedly connected by bolt 11 with portable plate 9, the bottom of pressing plate 10 is provided with the groove of arc；Also include being stuck in rail
On 3 rail heads and the controller 13 that can be acted with the roller bearings 12 of the fit depressions of pressing plate 10 and for control cylinder 8.
It should be noted that the pressing plate 10 is bolted with portable plate 9 and linked, this connection be it is dismountable,
So, the roller bearing that on the one hand multiple pressing plates 10 can be set and be engaged with pressing plate 10 in the bottom of portable plate 9 according to actual needs
12, on the other hand, for the rail 1 of different model, it both can directly disassemble pressing plate 10 and directly rail 1 had been applied by portable plate 9
Pressure, or in order to truly reflect the compression situation of rail 1, can also change roller bearing 12 or by roller bearing 12 and pressing plate 10 in the lump more
Change, meanwhile, it is this to be detachably connected the maintenance for also allowing for device.In addition, roller bearing 12 is stuck on the rail head of rail 3, i.e., such as Fig. 1 institutes
Show, the central radius of roller bearing 12 is small, two ends radius is big, and the width at the middle part of roller bearing 12 is engaged with the width of rail head of rail；Rolling
Groove of the middle part diameter of axle of axle 12 also with pressing plate 10 is adapted, so, and during pressure, roller bearing 12 can be stuck in the groove of pressing plate 10,
By the interaction between pressing plate 10 and roller bearing 12, more can really reflect the vertical pressure that rail is subject to, and rail 3 by
The vertical pressure arrived is stably balanced.
Further, the horizontal force application apparatus is separately positioned on the two ends of rail 3, the water with displacement measurement apparatus 2
Flat force application apparatus is jack, and the displacement measurement apparatus 2 is dial gauge.So, jack is applied to steel by one end of rail 3
The horizontal thrust of rail, the dial gauge of the other end then reads the horizontal displacement of corresponding rail 3.
In order that determining displacement is more accurate, the displacement measurement apparatus 2 is 3, and be separately positioned on rail 3 rail head,
The web of the rail and flange of rail portion.So, by the determining displacement of 3 diverse locations, measurement error is reduced, measurement accuracy is improved.
During utility model works, roller bearing is placed on rail and pushed down by the groove of pressing plate, controller control cylinder
Downward actuation, makes roller bearing be pressed on rail, so as to apply vertical pressure to it, further by the horizontal force application apparatus of rail one end
Horizontal thrust is applied to rail, the displacement measurement apparatus positioned at the rail other end determines the displacement of rail, so as to show that rail is indulged
Relation between resistance and vertical pressure, horizontal thrust, horizontal displacement.The utility model is simple in construction, easy to operate, adapts to
Property is good.
Although the embodiment of the present invention is the foregoing described, it will be appreciated by those of skill in the art that not
On the premise of the principle and essence of the present invention, various changes or modifications can be made to these embodiments, but these become
More protection scope of the present invention is each fallen within modification.
