It connects.When motor rotates forward, motor driven reaction frame is moved along the first direction of track 2；When motor reversal, motor driven is anti-
Power frame is moved along the second direction of track 2, and first direction is opposite with the extending direction of second direction.
Embodiment two:
Driving mechanism may include hydraulic cylinder and piston rod, and one end of piston rod is connect with hydraulic cylinder, piston rod it is another
End is connect with reaction frame 1, and while Driven by Hydraulic Cylinder piston rod is mobile, piston rod pushes reaction frame 1 to move along track 2.
Embodiment three:
Driving mechanism can be linear motor, and linear motor one end is fixed on pedestal 4, and the other end is connect with reaction frame 1,
Linear motor is able to drive reaction frame 1 and moves along track 2.
In some embodiments, as shown in Figure 1, III type fragment-free track slab static test bed of above-mentioned high-speed railway CRTS also wraps
Pedestal 4 is included, two tracks 2 are set on pedestal 4.The top surface of pedestal 4 is parallel to the horizontal plane, and the setting of pedestal 4 can guarantee two
The extending direction of track 2 is parallel to horizontal plane, guarantees that jack can uniformly act on power on track plates.
On the basis of the above embodiments, in order to enable the cost of pedestal 4 is lower, increase the stability of pedestal 4, pedestal 4
Material be concrete.Concrete has good intensity, and for steel construction, cost is lower.
In some embodiments, in order to enable track plates support base 3 laterally can carry out track plates along track plates
Support, additionally it is possible to track plates are supported along the longitudinal direction of track plates, above-mentioned III type fragment-free track slab of high-speed railway CRTS is quiet
Carrying testing stand further includes the track plates support base 3 between two tracks 2, and track plates support base 3 includes for along track
The cross-brace seat 31 that laterally track plates are supported of plate and for being supported along the longitudinal direction of track plates to track plates
Longitudinal bracing seat 32.
Above-mentioned track plates support base 3 combines cross-brace seat 31 and longitudinal bracing seat 32, is not required to during the experiment
Cross-brace seat 31 is hung, longitudinal bracing seat 32 is hung between two tracks 2 again.
When carrying out longitudinal section static load test to track plates, 32 pairs of track plates of longitudinal bracing seat are supported；When to rail
When guidance tape carries out cross section static load test, 31 pairs of track plates of cross-brace seat are supported.
On the basis of the above embodiments, in order to avoid replacement longitudinal bracing seat 32 and cross-brace seat during test
31, longitudinal bracing seat 32 includes the first support ontology 321, and cross-brace seat 31 is including the second support ontology 311 and set on second
Support the supporting pad 312 at 311 top of ontology, in which: as shown in Figure 1, the height of the second support ontology 311 is originally less than the first support
The height of body 321；Supporting pad 312 is detachably connected with the second support ontology 311, and supporting pad 312 and the second support ontology 311
The sum of height is greater than the height of the first support ontology 321.
Specifically, it is specifically described by taking Fig. 2 as an example, before the test, first passes through magnifying glass viewing track plates, lacked to initial
It is trapped into line flag.Then two reaction frames 1 are moved along track 2 to the both ends of track 2, then track plates are hung into track plates branch
It supports on seat 3, at this point, supporting pad 312 is set to the top of the second support ontology 311, due to supporting pad 312 and the second support ontology
The sum of 311 height are greater than the height of the first support ontology 321, and supporting pad 312 is directly supported track plates, and the first support is originally
Body 321 is not supported track plates, is then pressurizeed by the left and right ends of jack pair track plates, and it is horizontal to carry out track plates
Section static load crazing-resistance test.
After the static load crazing-resistance test of cross section, tensile region is observed with magnifying glass, observes crack situation, it will after observation
Track plates lifting or jacking 5-10cm, support the supporting pad 312 on ontology 311 to take down for second, so that the first support ontology
321 are directly supported track plates, are then pressurizeed by the upper and lower ends of jack pair track plates, and it is vertical to carry out track plates
Section static load crazing-resistance test.After the static load crazing-resistance test of longitudinal section, reaction frame 1 is moved along track 2 to the both ends of track 2 again
It is dynamic, test is completed after being transferred from track plates.Tensile region is observed with magnifying glass after test, observes crack situation.
In some embodiments, in order to enable supporting pad 312 stable can be supported track plates, supporting pad 312
For rubber pad.Rubber has good elasticity, effectively track plates can be avoided to roll.
In some embodiments, as shown in Fig. 2, the first support ontology 321 includes one and longitudinally extends along track plates
First square steel.
When carrying out longitudinal section static load test to track plates, the first square steel can be supported track plates, so that track
Plate can generate bending after being pressurized, and crack.
In some embodiments, as depicted in figs. 1 and 2, in order to avoid in experimentation the first square steel to track plates gate
Muscle generates obstruction, and the first square steel is equipped with the first opening 322 passed through for track plates door rebar.
First opening 322 enables to the door rebar of track plates to protrude into the first square steel, avoids carrying out track plates vertical cut
When the static load test of face, needs to cut off the gate reinforcing bar cutting at track plates bottom, simplify experimental procedure, effectively shorten reality
Test duration.
Specifically, as shown in Fig. 2, the extending direction for extending perpendicularly to the first square steel of the first opening 322.
In some embodiments, as shown in Fig. 2, in order to enable second support ontology 311 can it is stable to track plates into
Row support, the second support ontology 311 includes the second square steel 3111 being laterally extended each along track plates, third steel 3112, the
The extending direction of four square steel 3113 and the 5th square steel 3114, the second square steel 3111 and third steel 3112 is overlapped, four square steel
3113 and the 5th square steel 3114 extending direction be overlapped.
When carrying out cross section static load test to track plates, the second square steel 3111, third steel 3112, four square steel
3113 and the 5th square steel 3114 track plates are supported jointly, guarantee support stability.
In some embodiments, on the second square steel 3111, third steel 3112, four square steel 3113 and the 5th square steel 3114
It is equipped with the second opening 3115 passed through for track plates door rebar.
Second opening 3115 enables to the door rebar of track plates to protrude into the second square steel 3111, third steel the 3112, the 4th
In square steel 3113 and the 5th square steel 3114, when avoiding carrying out cross section static load test to track plates, need track plates bottom
Gate reinforcing bar cutting is cut off, and experimental procedure is simplified, and effectively shortens experiment duration.
Specifically, as shown in Fig. 2, the extending direction of the second opening 3115 is parallel to the extending direction of the second square steel 3111.
