Embodiment
Below in conjunction with drawings and Examples, describe the present invention:
Below in conjunction with accompanying drawing, describe a kind of structure and Installation and Debugging mode thereof of detachable internals maintaining support in detail.
It mainly comprises the work trestle using when as Figure 1-5, the present invention is a kind of nuclear power station reactor inner member maintenance and repair: stand 1, lower adjusting pad 2, platform framework 3, positioning component I4, upper adjusting nut 5, positioning component II6, upper adjusting pad 7, lower adjusting nut 8.
Wherein, stand 1 comprises crossbeam 9, joist steel 10, supplemental support 11, keeper 12, dull and stereotyped 13, joist steel 10 is positioned at dull and stereotyped 13 both sides, it is middle and vertical with joist steel 10 that crossbeam 9 is welded on joist steel 10, contour, parallel and vertical with flat board 13 between the plane of orientation 22 of two keepers 12, auxiliary supports 11 is welded on the outside of joist steel 10, is positioned at the position corresponding with platform framework 3.Register pin 23 in the main positioning component II6 of stand 1 upwards inserts in gathering sill 16 from platform framework 3, after four back-up blocks of positioning component I4 and platform framework 3 welding, not only to make these four points in same plane, but also will guarantee that the plane that these four points form is parallel with the upper locating surface of the rear positioning component II6 of insertion platform framework 3.
Wherein, platform framework 3 structures comprise: locating surface 18, lower reinforcing plate part 19, lower adjustment support member 20, upper reinforcing plate part 21 under locating surface 17, side in square main frame 14, upper adjustment support member 15, upper gathering sill 16, side, wherein, main frame 14 and upper reinforcing plate part 21, lower reinforcing plate part 19, upper adjustment support member 15, lower adjustment support member 20 difference welding fabrications, on platform framework 3 upsides, under locating surface 17 and side, locating surface 18 has alternate position spike in the horizontal direction.
Between stand 1 and platform framework 3, by behind register pin 23 location on positioning component II6, use lower adjusting nut the two is fastenedly connected.
As shown in Figure 8, the structure of positioning component I4 is for being drilled with the block location structure of rack positioning hole 27, and positioning component I4 has four, by the mode of welding, is fixed on platform framework 3.When positioning component I4 and platform framework 3 welding fabrication, the plane 4 that four points of need assurance positioning component I4 form is parallel with two upper plane of orientations in positioning component II6, needs to guarantee that support plane of orientation is vertical with the guide rail in stand simultaneously
As shown in Figure 9, positioning component II6 comprises locating piece 23, upper locating surface 22, register pin 24 and upper adjustment bolt 25, one end welding of locating piece 23 have a upper adjustment bolt 25, other end top at locating piece 23 processes step, make the height of step be greater than thick 2 times of the average leg of joist steel at gathering sill 16 places on platform framework 3, locating surface 22 is formed at the bottom of step, and register pin 24 is vertically welded on locating piece 23 steps.Positioning component II6 is contained in the upper gathering sill 16 of platform framework 3, and upper adjustment bolt 25 inserts in the hole of upper adjustment support member 15, can make locating piece 23 do front and back position adjustment while adjusting the nut 5 on bolt 15 in turn.The keeper 12 of upper adjusting pad 7 in stand 1 and inserting between the positioning component II6 in platform framework 3, changes in, adjusting pad 7 thickness can change stand 1 and pile center line verticality with respect to positioning component I4 formation plane in flat board 13.
Can anticorrosion in order to guarantee to enter in whole support water section (being riser and platform framework), durable in use, good rigidly, adopt stainless steel to make.Other member is used ordinary low-carbon steel.
Installation process of the present invention is as described below:
1 first by positioning component I4 and platform framework 3 welding fabrications, make four fulcrums of positioning component 4 in same plane;
2 pack positioning component II6 in upper gathering sill 16 into, and then by stand 1, the side-locating face 17 along platform framework 3 from top to bottom slowly puts down, and the pilot hole of keeper 12 in stand 1 is packed on the register pin 24 in positioning component II6;
3 by lower adjustment bolt 8 through the hole between joist steel 10 and supplemental support 11 and the hole in lower adjustment support member 20, with lower adjusting nut 8 lockings, and use adjusting nut 5 and lock;
When the verticality of 4 plane of orientations when stand 1 symmetrical center line and positioning component I4 formation does not meet the demands, can, by making two upper adjusting pad 7 thickness different, adjust the symmetrical neutral line of riser 1 and the verticality of four positioning component I4 formation planes; When adjusting nut 5 is gone up in two of turns respectively, can adjust the verticality on other direction;
5 when step 4 still can not meet the demands, can also descend adjust mat thickness by change, and stand 1 symmetrical center line is adjusted with respect to the verticality that is welded on the positioning component plane that I4 forms in platform framework 3 in the position that coordinates adjusting nut 5 in turn to change positioning component II6.
6 when stand 1 integral body does not meet the demands with respect to the symmetry of platform framework 3, can be that position and the lower adjusting nut 8 of positioning component II6 and the thickness that changes lower adjusting pad 2 are adjusted symmetry by adjusting nut in turn 5.
