Embodiment
As shown in Figure 1, 2, the present invention includes frame body, described frame body is by four horizontally disposed crossbeams, and the adjustment rack 2 of the left fixed mount 1 and right-hand member that are arranged on described crossbeam left end forms; The upper and lower crossbeam 3,4 of described frame body is longitudinally fixed with guide rail respectively, described guide rail is provided with left tressel 5 and right tressel 6, described left and right tressel 5,6 to be rolled with described guide rail by roller 7 with upper and lower crossbeam 3,4 respectively and coordinates; Longitudinally spaced apartly respectively on upper and lower crossbeam 3,4 be provided with multiple jack 8,9, left and right tressel 5,6 is connected with upper and lower crossbeam 3,4 respectively by latch 10,11; Arrange the first load cylinder 12 between left fixed mount 1 and left tressel 5, the cylinder body of described first load cylinder 12 is fixed on left fixed mount 1, and the piston rod end of the first load cylinder 12 is fixedly connected with left tressel 5; Arrange the second load cylinder 13 between adjustment rack 2 and right tressel 6, the cylinder body of described second load cylinder 13 is fixed on adjustment rack 2, and the piston rod end of the second load cylinder 13 is fixedly connected with right tressel 6.First, second load cylinder 12,13 described is respectively setting up and down two.Described left fixed mount 1 bottom is fixed by two bearing pins 14,15 and described sill 4, and its top is fixed by a bearing pin 16 and described entablature 3; Described adjustment rack 2 is provided with the regulating wheel 17 coordinated with described non-orbiting scroll, adjustment rack 2 is connected with upper and lower crossbeam 3,4 by register pin 18,19.
Left fixed mount 1 of the present invention is positioned at frame body left end and fixes with swivel pin, can not move; The adjustment rack 2 of left and right tressel 5,6 and right-hand member can roll along upper and lower beam crossbeam 3,4.Upper and lower crossbeam 3,4 is provided with multiple jack 8,9 at longitudinal direction, crotch size in the convenient length adjustment test bed framework according to being verified column, lifting jack.Left and right tressel 5,6 arranges roller 7, adjustment rack 2 arranges regulating wheel 17, simultaneously along the longitudinal direction guide rail is set respectively on upper and lower crossbeam 3,4 relative surfaces, roller 7, regulating wheel 17 can be rolled along the guide rail of upper and lower crossbeam 3,4, the setting of this rolling structure can prevent the leaning forward of left and right tressel 5,6 and adjustment rack 2, hypsokinesis, ensures that motion state is steady.In addition, panel can be set on guide rail, the wearing quality of guide rail can be increased, and effectively can control guiding clearance.Load cylinder has 4, each 2 of two ends, left and right, and effectively can load load by lifting test, the column, the lifting jack that meet " large resistance, large-diameter, Long Distances " carry out pressure testing test.
Frame body of the present invention is fixed by lower margin Connection Block 20 and ground, left fixed mount 1 adopts two swivel pins and sill 4 to fix at framework left end, top is connected with entablature 3 by a swivel pin, make entablature 3 can carry out the upset of certain angle in device assembles process, be convenient to left and right tressel 5,6 and the installation between adjustment rack 2 and upper and lower crossbeam 3,4.Because left and right tressel 5,6 and adjustment rack 2 need to carry out position adjustment according to tested column, lifting jack, therefore left and right tressel 5,6 adopts latch to be connected with lower and upper cross-member 3,4, and adjustment rack 2 is connected with upper and lower crossbeam 3,4 by register pin 18,19.
The test of column of the present invention, lifting jack, carry out according to following steps:
1. Adjustment Tests platform span
To be placed between left and right tressel 5,6 by test column or lifting jack 21, according to the span of equipment under test adjusted size testing table, be specially: constantly stretching out by pressurizeing, regaining the second load cylinder 13, simultaneous wheels inserts the register pin 18,19 that the latch 11, the adjustment rack 2 that pull out right tressel 6 and be connected with crossbeam are connected with crossbeam, realizes " step type is from moving " and carrys out Adjustment Tests table frame home record size.
2. carry out " interior loading " test
By the span adjusted, left and right tressel 5,6 is fixed respectively by latch 10,11 and upper and lower crossbeam 3,4, carry out various " interior loading " test by national standard (GB 25974.2) or European standard (EN1804-2).
3. carry out " loading " test outward
First fixed by latch 11 with crossbeam by right tressel 6, pressurize to the first load cylinder 12, piston rod stretches out, and promotes left tressel 5 and moves, compress tested column or lifting jack 21, carries out allowing pressure test.If tested column or lifting jack 21 stroke larger, now left tressel 5 can be fixed by latch 10 with crossbeam, extract the latch 11 of right tressel 6 out simultaneously, second load cylinder 13 is pressurizeed, piston rod stretches out, promote right tressel 6 to move, the tested oil cylinder of continuation compression carries out the second level allows pressure test.
