The installation process and operation principle of the present invention is as follows：
1st, by the installation of test piece：Adjust the adjusting screw on auxiliary support frame so that it is slightly above Shi Jishiyong height
Degree, ready steeraxle is placed on adjusting screw head；Reduce adjusting screw height so that two ends are fallen within steeraxle
In support meanss 3, now, retain certain gap between the end of adjusting screw and steeraxle pontic, with pontic stress elasticity
Still 5~10mm or so gap is reserved after deformation to be defined；
2nd, the adjustment of initial tension of spring：After being installed by test piece, steeraxle is in free horizontality, and steeraxle is laid particular stress on
The spring of side is compressed, and is defined by reality by decrement, is adjusted and is locked the nut on guide pillar reduced diameter section；At another lateral spring
In non-Pre strained state, the supporting screw of adjustment guide pillar end just touches frock by supporting screw head and is defined；
3rd, the equilibrium principle of power is laid particular stress on：By being configured to the spring pre-tightening amount for laying particular stress on side and non-weighting side, two bullets
The difference of the pretightning force of spring relative to the pontic shaft end centre of gyration torque, equal to weighting weight relative to the centre of gyration turn
Square, now steeraxle reach poised state, steeraxle keeps balance；
4th, the holding of poised state when workpiece is tested：Because the ratio of rigidity of two springs is equal to it relative in steeraxle revolution
The lever ratio of the heart, therefore when being bent by test specimen, two springs are equal relative to the torque that the drive axle centre of gyration is produced, workpiece
Stress point can keep its original state vertical descending without rotating；
5th, pontic fracture protection is turned to：When steeraxle pontic is broken, dropped down onto under its fracture location is rapid at the top of supporting screw
And do not continue to, while the Guide column component of Auxiliary support both sides can effectively prevent its rolling from falling, it is to avoid security incident is sent out
It is raw.
The beneficial effects of the present invention are：1) thoroughly security protection of the forklift steering bridge in process of the test is solved to ask
Topic；2) solving in steeraxle process of the test can neither interfere it to deform, while the contradiction effectively protected again；3) due to not adopting
The mode that is tensed with chain, it is to avoid chain produces pulling force in process of the test, effectively increases test accuracy；4) eliminate because
Chain pull causes micro lateral displacement to accumulate, and eliminates potential safety hazard；5) workpiece is pulled by chain when avoiding pontic fracture
Overturn the risk fallen；6) avoid testing crew needed in process of the test repeatedly it is strong to the work that is adjusted by test piece
Degree.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to the model of the present invention
Enclose and be defined, on the premise of design spirit of the present invention is not departed from, technical side of the those of ordinary skill in the art to the present invention
In various modifications and improvement that case is made, the protection domain that claims of the present invention determination all should be fallen into.
