In order to realize the purpose of this utility model, the utility model adopts following technical scheme to be achieved:
A kind of column, lifting jack testing table, comprise main body frame and hydraulic control system, main body frame is to consist of four cross main-bars, a tested case and a loading case, with bearing pin, the pin shaft hole by cross main-bar two ends is formed by fixedly connecting with the pin shaft hole at tested case and the loading longitudinal two ends of case respectively four cross main-bars, four cross main-bars, by upper and lower two frame plates of being connected to form of four vertical main-bars, support with stay pipe between upper and lower two frame plates; Hydraulic control system is for the hydrostatic control of tested column and lifting jack; It is characterized in that: also comprise live loaded case and load lifting jack, wherein: live loaded case is arranged at two frame plates, the tested casees up and down of main body frame and loads between case, the longitudinal two ends of live loaded case are provided with pin shaft hole, and connect by the bearing pin pin shaft hole corresponding with four cross main-bars; Load lifting jack and be arranged between upper and lower two frame plates, its piston head pushes up mutually with live loaded case, and its cylinder bottom is seated at and loads on case.
Described tested case, loading case and the longitudinal two ends of live loaded case are equipped with double-pin axis hole.
On described cross main-bar, the installation site of corresponding tested case, loading case and live loaded case is provided with double-pin axis hole.
The both lateral sides of described live loaded case is provided with column cap seat or needling.
The horizontal inner side of described tested case and loading case is equipped with cylinder body needling.
In described stay pipe, be provided with back shaft, the lower end of back shaft is placed in the blind end of stay pipe, and upper end is connected with upper frame plate by gland nut.
Beneficial effect
1, the column two ends clamp device of this testing table adopts one end to fix, and the structure that one end can be movable, is conducive to the test of different length column;
2, this testing table column two ends clamp device, all adopts body structure, changed like product often therefore part damage and the persistent ailment of scrapping, extended permanance and the life-span of testing table.
3. simple in structure, low cost of manufacture, wide adaptability, is convenient to install;
Accompanying drawing explanation
Fig. 1 is the front view of a kind of column, lifting jack testing table;
Fig. 2 is the vertical view of a kind of column, lifting jack testing table;
Embodiment
By reference to the accompanying drawings, the utility model is described further:
A kind of column, lifting jack testing table, comprise main body frame 1, live loaded case 4, load lifting jack 10 and hydraulic control system, main body frame is by four cross main-bar 1-1, a tested case 2 and a loading case 3 form, with bearing pin, the pin shaft hole 1-2 by cross main-bar 1-1 two ends is formed by fixedly connecting with the double-pin axis hole 1-2 at tested case 2 and loading case 3 longitudinal two ends respectively four cross main-bar 1-1, and form upper and lower two frame plate 1-3, between upper and lower two frame plate 1-3, with stay pipe 6, support, in described stay pipe 6, be provided with back shaft 7, the lower end of back shaft 7 is placed in the blind end of stay pipe 6, upper end is connected with upper frame plate 1-3 by gland nut 5, the horizontal inner side of tested case 2 and loading case 3 is provided with cylinder body needling 8, hydraulic control system is for the hydrostatic control of tested column and lifting jack, live loaded case 4 is arranged at two frame plate 1-3, the tested casees 2 up and down of main body frame and loads between case 3, can with bearing pin by the pin shaft hole 1-2 on cross main-bar 1-1 with it longitudinally the double-pin axis hole 1-2 at two ends connect and fixing live loaded case 4, for fixing of tested column or lifting jack, the both lateral sides of live loaded case 4 is provided with column cap seat 9 or needling 9, loading lifting jack 10 is arranged at upper and lower two frame plate 1-3, live loaded case 4 and loads between case 3, for the loading of testing.
