A kind of transform heavy duty supporting mechanism, described mechanism comprises telescopic oil cylinder 2, base 3, support roller case 4, rigid support seat 5, rigid support cushion block 6, connecting rod 7, wherein, described base 3 forms overall structure form with rigid support seat 5 by welding procedure, support roller case 4 is by nested mounting means, by bearing pin, be installed between base 3 and rigid support seat 5, rigid support seat 5 is inserted in support roller case 4; Connecting rod 7 is U-shaped structure, through reserved through hole on base 3, support roller case 4 and rigid support seat 5, make two ends connect respectively telescopic oil cylinder 2 and be positioned over the rigid support cushion block 6 on rigid support seat 5, under the promotion of telescopic oil cylinder, drive rigid support cushion block 7 to slip into, skid off rigid support seat 5.
Support roller case is rolling support load bearing component, and rolling support bearing capacity acts on support roller tread, and rigid support seat is the parts that bear static overload, and bearing capacity acts on rigid support seat upper surface by rigid support cushion block.
Be subject to limited space, support roller bearing space and rigid support seat bearing space must be overlapping.Support roller box body is designed to semiclosed, leaves suit rigid support seat opening, and rigid support seat makes bearing surface be placed in relevant position through support roller case, and this bearing surface and support roller carrying tread leave the discrepancy in elevation.
Support roller case carrying bearing pin is installed on base riser through rigid support seat, and bearing capacity acts on base riser, and rigid support seat does not bear bearing pin load; Rigid support seat and base are integrated into rigid connection by welding procedure.
Under the cooperation of support oil cylinder, coupling bar, under the promotion of telescopic oil cylinder, drives rigid support pad to slip into and skids off rigid support seat, and when rigid support pad slips into rigid support seat, rigid support pad upper surface exceeds support roller tread, becomes bearing surface and bears static overload; When rigid support pad skids off rigid support seat, support roller tread exceeds rigid support seat upper surface, and support roller tread becomes bearing surface and bears the heavy duty of rolling.
Transform of the present utility model heavy duty supporting mechanism is arranged on support roller case on the custom-designed base that is integrated with rigid support seat according to designing requirement, under the cooperation of support oil cylinder, by telescopic oil cylinder, by coupling bar, promote rigid support cushion block and slide into and shift out rigid support seat, realize the conversion of equipment rigid support and rolling support pattern.
In nose girder, supporting leg is a most important carrying supporting leg in nose girder supporting leg, and when nose girder bears beam sheet load, Beam transportation vehicle load and self load, in heavy condition, nose girder is relative with nose girder supporting leg static, is static state carrying, and load is on rigid support cushion block; When taking out nose girder, nose girder supporting leg only bears nose girder deadweight, is underloading, and nose girder and supporting leg require there is relative motion, by support roller, are carried; The bearing mode of these two kinds of operating modes just completes by load transfer described in the utility model mechanism.
Beneficial effect
(1) supporting mechanism of the present utility model, by adopting the unique design scheme of support roller case and the overlapping installation of fixed supporting seat, has well solved the limited difficult problem in structure space position;
(2) coupling bar adopts U-shaped structure, and the mode being connected with telescopic oil cylinder with rigid support seat through base, support roller case has not only solved structure space limitation problem but also realized functional requirement, has well utilized and has had living space, and structure arrangement compact and reasonable is effective;
(3) adopt telescopic oil cylinder promotion coupling bar to drive rigid support pad to slip into and skid off rigid support seat, conversion between realization each bearing surface in differing heights aspect, thereby reach the conversion of static overload and rolling load different bearer mode, working security and stability have been improved, increase service life of equipment, improved efficiency of construction.
