1st, because test stand causes from great, the experimental sample species experimental implementation trouble, workload big more;
2nd, in order to meet different experiments requirement, experimentation middle cross beam needs to carry out upper-lower position adjustment, due to crossbeam ratio It is heavier, it is troublesome in poeration, workload is big, and security is low;
3rd, the requirement of various structures experiment can not be met;
4th, in the structural test piece experiment for carrying out conducting oneself with dignity larger, test specimen is correct in place troublesome in poeration, and is put in test specimen During easily collide destruction;
5th, installing with being needed in later stage debugging by outside crane gear, increase installation and the use cost in later stage.
Utility model content:
The purpose of this utility model is the deficiency existing for existing structure static trial, there is provided a kind of new structure static(al) Test loading experiment frame, it is possible to achieve self-regulation combination beam height, the height that bearing is loaded by adjusting adapt to different height Test component, and heavier test component can be lifted by crane and installed using equipment of itself, so as to meet most knots The requirement of structure slow test.
To achieve the above object, the utility model uses following technical scheme:
A kind of new structure slow test loading experiment frame of the present utility model, by support column, combination crossbeam, back timber, liquid Jack, crossbeam self-regulation electric block, lifting test specimen electric block, loading bearing composition are pressed, wherein, support column bottom passes through Bolt is fixed on rigid ground, and combination crossbeam is connected by bolt hole with support column, and adjustable height;Combination crossbeam bottom is set It is equipped with track, hydraulic jack and lifting test specimen electric block to connect with combining crossbeam by track, and can freely adjusts position Put;Back timber is located above support column, two altogether, two back timbers by bolt respectively with the length on the steel plate of supported on both sides top end Circular bolt holes are connected, and crossbeam self-regulation electric block is connected by bolt with back timber.Bearing is loaded under crossbeam is combined just Side, is positioned over rigid ground.Back timber is i shaped steel, and support column section is flute profile, and it is convenient that screw is evenly distributed with support column Combine the regulation up and down of crossbeam.
A kind of new structure slow test loading experiment frame of the present utility model, it is further characterized by:Load bearing It is made up of base, backing plate and weighted platform.Its center base is made up of bottom plate, angle steel and spacer bar, backing plate and weighted platform bottom Portion is provided with positioning hole, and base, backing plate and weighted platform pass through spacer bar split.
Compared with existing structure slow test loading experiment frame, the beneficial effects of the utility model have:
(1) without outside crane gear, height tune is carried out to grouped by itself crossbeam using self-regulation electric block Section, greatly reduce the difficult operation of experiment, the problems such as testing expenses are high;
(2) support with adjustable is adapted to the height of different test specimens;
(3) by lift test specimen electric block can conveniently lifting, it is accurate in place some from great structural test piece, and Reduce the infringement to test specimen during test specimen is put.
(4) most of finite element analysis can be met by sized.
(5) the utility model is simple to operate, greatly reduces manual labor during testing, adds deadweight bulk specimen examination Security during testing.
