Detailed description of the invention
Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model instruction.
Embodiment 1
With this body weight of continuous casting rotary table 224 tons, the bearing replacing of the direct 4325mm of bearing is example, as follows,
As shown in Figures 1 to 3, a kind of continuous casting turret revolving bearing replacing saddle arm jacking apparatus comprises saddle arm bracing or strutting arrangement 1, hydraulic jacking device 2, bearing transverse moving support 3.
Described saddle arm bracing or strutting arrangement 1 comprises steel structure load-bearing bearing 4 under rotary table saddle arm 6 and rotary table internal rigid reinforcing member 5, steel structure load-bearing bearing 4 adopts 400H shaped steel intersecting parallels to be superimposed to immediately below saddle arm 6, and leave the gap of placing hydraulic jack 11 between steel structure load-bearing bearing 4 and saddle arm 6, rotary table internal rigid reinforcing member 5 adopts the solid drawn pipe of 4 D273*12, be welded to saddle arm back timber, restriction saddle arm to top offset, make twisted branch structure become rigid construction.
Described hydraulic jacking device 2 comprises the 200T hydraulic actuating cylinder of 4 same size models, synchronous control system, cushion block 400*400, height 50mm and some other models, quantity about 100.
Described bearing transverse moving support 3 scaffolding height is a little less than rotary table base 7, width is identical with bearing 8 diameter, prolongation distance is greater than the position across the nearly beam-ends maximal work of interior installed driving, and described rack upper surface installs the steel pipe 9 of D32, as the track of bearing slippage.
The utility model is specially following steps in construction:
The first step, saddle arm support system is set: rotary table is turned to holding fix, according to load-bearing demand, 400H shaped steel intersecting parallels is overlapped on immediately below saddle arm 6, the horizontal deflection of the upper surface of this load-bearing bearing should more than 2mm, the rigidity of rotary table inside is reinforced, and adopts the twisted branch displacement of D273 steel-pipe welding locking saddle arm.Bearing transverse moving support is set simultaneously;
