Abstract
A kind of elastic supporting block preburied iron base pull-out bond test device, the device includes boosting frame, T-type pedestal, hold-doun nut, plain washer, transmission rod, guarantee the verticality and axial line of transmission rod and preburied iron base by T-type pedestal, hold-doun nut and plain washer, which has the characteristics that easy to operate, accurate positionin.Transmission rod upper end is equipped with hollow type jack, i.e. hollow type jack is arranged above boosting frame by transmission rod, using nut check transmission rod, under the action of hydraulic pump, hollow type jack successively passes to transmission rod, T-type pedestal and preburied iron base by boosting frame generated reaction force, finally realizes the test objective.
Description
Technical field
The utility model relates to a kind of elastic supporting block preburied iron base pull-out bond test devices, belong to railway engineering field.
Background technique
Since elastic supporting block preburied iron base is perpendicular to 1:40 support rail face, during preburied iron base pull-out bond test, examination
Experiment device is placed in 1:40 slope surface and carries out, and transmission rod cannot be guaranteed under the effect of gravity it is vertical with 1:40 slope surface, in turn
It cannot be guaranteed that the vertical stress of preburied iron base.Therefore how to guarantee transmission rod be overlapped with preburied iron base axial line and fixation seem to
It closes important.
Summary of the invention
The purpose of this utility model provides a kind of structure aiming above situation and is simple and convenient to operate, is accurately positioned, full
The experimental rig of sufficient elastic supporting block preburied iron base pull-out bond test.
The technical solution of the utility model is: a kind of experimental rig of elastic supporting block preburied iron base withdrawal resistance, described
The experimental rig includes boosting frame, T-type pedestal, hold-doun nut, plain washer, transmission rod and jack;
The boosting frame is welded-steel plate construction, i.e. boosting frame is welded by a transverse slat and two risers,
In, the transverse slat of boosting frame is equipped with central through hole;For installing transmission rod, transmission rod lower end is equipped with screw thread;
The T-type pedestal quick and precisely controls transmission rod by hold-doun nut, plain washer on preburied iron base notch
With the verticality and axial line of preburied iron base, make the vertical stress of its preburied iron base;
The transmission rod upper end is equipped with hollow type jack, i.e. hollow type jack is being reinforced by transmission rod setting
Above frame, using nut check transmission rod, under the action of hydraulic pump, hollow type jack passes through boosting frame generated reaction force
Transmission rod, T-type pedestal and preburied iron base are successively passed to, finally realizes the test objective.
Detailed description of the invention
Fig. 1 is the operation principle schematic diagram of the utility model；
Fig. 2 is the utility model dowel bar structure schematic diagram；
In figure: 1- boosting frame, 2-T type pedestal, 3- hold-doun nut, 4- plain washer, 5- transmission rod.
Specific embodiment
Referring to attached drawing, a kind of experimental rig of elastic supporting block preburied iron base withdrawal resistance, described experimental rig includes
Boosting frame 1, T-type pedestal 2, hold-doun nut 3, plain washer 4, transmission rod 5 and jack 6;
The boosting frame 1 is welded-steel plate construction, i.e. boosting frame 1 is welded by a transverse slat and two risers,
In, the transverse slat of boosting frame 1 is equipped with central through hole;For installing transmission rod 5,5 lower end of transmission rod is equipped with screw thread;
The T-type pedestal 2 quick and precisely controls biography by hold-doun nut 3, plain washer 4 on preburied iron base notch
The verticality and axial line of power bar 5 and preburied iron base make the vertical stress of its preburied iron base;
5 upper end of transmission rod is equipped with hollow type jack 6, i.e. hollow type jack 6 is arranged by transmission rod 5
1 top of boosting frame, using nut check transmission rod 5, under the action of hydraulic pump, hollow type jack 6 is generated by boosting frame 1
Counter-force successively pass to transmission rod 5, T-type pedestal 2 and preburied iron base, finally realize the test objective.
