It sets, thus realize the left and right centering of concrete test block 4, it can be to avoid in the prior art using inconvenience caused by auxiliary center line.
In the present invention: the concrete test block centralising device is mounted on pressure testing machine, specifically, the rail
Road sliding block 10 can left and right movement be mounted on the reaction frame 1, and positioned by the orbit adjusting screw rod 11；Described
One adjusting screw component 13 is fixedly mounted on the reaction frame 1, and can be stretched along the forward and backward direction moved of the platform trolley 12
Long or shortening；The platform trolley 12 is between the lower platen 3 and top board 7；
The concrete test block 4 is shelved on the platform trolley, and Light deformation detection is additionally provided on the concrete test block 4
Elasticity modulus detector 6 can also be arranged on the concrete test block 4 in instrument 5.
The utility model can move on to platform trolley 12 outside reaction frame 1 along trolley track 9, easily place so mixed
Solidifying soil test block 4 and installation Light deformation detector 5 etc. are also easy to concrete test block 4 according to being carved since observation sight is good
Auxiliary center line is placed on centre；During the test, by platform trolley 12 be pushed into reaction frame, the first of 9 end of trolley track
Platform trolley 12 can be limited in the position of 9 front and rear direction of trolley track by adjusting screw component 13, guarantee that concrete test block 4 exists
Front and rear direction centering；The centering in the left and right direction of concrete test block 4 is using 9 centering of trolley track set up, when starting test,
2 piston of jack starts to move up, and drives lower platen 3 to move up simultaneously, after lower platen 3 touches platform trolley 12, starts to make platform
Trolley 12 leaves trolley track 9, and when concrete test block 4 encounters top board 7, concrete tries 4 BOB(beginning of block) stress, Light deformation detection
Instrument 5 has reading, when being loaded into specified value, can using computer line computation concrete test block 4 offset, it is then very heavy
2 off-loads are pushed up, after concrete test block 4 is detached from top board 7, are adjusted according to offset calculated (Y-direction) adjustment described first
Screw component 13 moves backward platform trolley 12 Xiang Qianyi or on trolley track 9, realizes forward and backward centering；Since platform is small
Vehicle 112 has pushed away from trolley track 9, so orbit adjusting screw rod 11 is adjusted according to offset calculated (X-direction), it can be with
Left and right moving trolley track 9, after platform trolley 12, which is moved down, to be engaged with trolley track 9, can make platform trolley be moved to the left or
It moves right, realizes left and right centering, in addition can easily pull out platform trolley 9, replace next concrete test block 4.
In this embodiment, described first 12 front end of platform trolley or rear end described in 13 face of screw component are adjusted
One end is equipped with magnet；It is additionally provided on the reaction frame 1 and is adjusted for carrying out the second of left and right positioning to the platform trolley 12
Screw rod group 14 is saved, described second adjusts the left or right of platform trolley 12 described in 14 face of screw component, and described second is adjusted
An end of 12 left or right of platform trolley described in 14 face of screw component is equipped with magnet.The first of 9 end of trolley track
Platform trolley 12 can be sucked in the magnet on screw component 13 front end or rear end are adjusted, platform trolley 12 is located in and is set up
Forward and backward position on, guarantee concrete test block 4 in front and rear direction in；By adjusting the realization of orbit adjusting screw rod 11
After left and right centering, screw component 14 can be adjusted by adjusting second, the magnet on the second adjusting screw component 14 be sucked flat
Platform trolley 12 is located on the left and right position set up by the left or right of platform trolley 12, guarantees that concrete test block 4 exists
Centering on left and right direction；Second adjust screw component 14 cooperation under, it is ensured that platform trolley 12 it is forward and backward, left,
Stability after right centering.
In this embodiment, the trolley track 9 is triangle track.Trolley track 9 is triangle track, can be with
Guarantee that automatic and trolley track 9 is overlapped when platform trolley 12 falls.Since in test, concrete test block 4 is according to auxiliary
What center line was placed, so the offset of concrete test block 4 is not very big, generally millimeter rank；When according to being calculated
Offset (X-direction) adjust orbit adjusting screw rod 11, the distance of the left and right movement of trolley track 9 is also millimeter, when platform trolley
12 move down, since there is pico- movement in position of the trolley track 9 on left and right direction, and since trolley track 9 is the rail of triangle
Road, so the wheel of platform trolley 12 is under the action of the inclined-plane of the track of triangle, it is easy to engage with trolley track 9, from
And realize left and right movement.
In this embodiment, the first adjusting screw component can be simple feed screw nut pair, can be complexity
Servo-system is used for Accurate Position Control.
In this embodiment: the trolley track 9 forward and backward can be slidably mounted in the rail slider 10.By
It forward and backward can be slidably mounted in the rail slider 10 in trolley track 9, it in test, can be out of reaction frame 1 by trolley
Track 9 is extracted out, and the progress of test is facilitated, and in addition after the completion of upper test, trolley track 9 can be pushed into reaction frame 1, be saved empty
Between, facilitate normal ambulation in laboratory；In addition directly it can also realize platform trolley 12 in reaction frame by moving trolley track 9
Disengaging.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
