On, the rightest short track is to be directly placed on the 3rd right cap plate of heap poststack, after overhauling, then works as inter panel
After block tiling resets, short track is taken out, the tiling of the most remaining cover plate block is resetted.
As shown in figs. 5 and 9, hydraulic jack 3 is risen by hydraulic pressure or is fallen by external drive mechanism, described hydraulic pressure thousand
Jin top 3 includes bottom mounting seat 12, engaging mechanism 13, hydraulic jack sleeve 14, lifting column 15 and supporting plate 16, during work, work
The engaging mechanism 13 of action bars Yu hydraulic jack is carried out power transmission by the installing hole on cover plate 4 by people, then rotates behaviour
Make lifting column 15 increase as bar, thus drive supporting plate 16 cover plate block above to rise；During decline, workman only needs opposite direction to rotate behaviour
Making bar just can make lifting column 15 decline, thus drives supporting plate 16 cover plate block above to decline.
As shown in Figure 7 and Figure 8, described draw-in groove is regular hexagon draw-in groove, and described sleeve 111 is positive six prismatics；Described liter
The other end of fall bar 71 is connected with lifting supporting plate, and described lifting supporting plate is positioned at the bottom of described end cover plate；Described elevating lever
One end of 71 is connected by bearing 73 is fixing with described nut 72, and described nut 72 is arranged on the inner ring of described bearing 73, described
Elevating lever 71 is arranged on the outer ring of described bearing 73, and the inner ring of this bearing 73 rotates, and outer ring is motionless；Another of described elevating lever 71
Hold can fix through the bottom of described fluting with described end cover plate and be connected, it is possible to do not fix；Described turning handle 112 is circle
Cylinder is also vertically arranged, described cylindrical lower end is fixed on the one end connecting cross bar, the other end of described connection cross bar and institute
State the fixing connection in upper end of sleeve 111；The lower end of described leading screw 74 is fixed on the outer wall in concrete tunnel 1 by fixing seat.
Described leading screw 74 is positioned on the front outer wall in described concrete tunnel 7, and described nut 72 is near concrete tunnel 7
Side is connected by bearing 73 is fixing with the front end of described elevating lever 71, and described concrete tunnel 7 has in order to elevating lever 71
The fluting moved up and down, the rear end of described elevating lever 71 is positioned at the bottom of described end cover plate through described fluting；Pass through people
Work rotates handwheel, handles screw mechanism and makes down or up one layer of the end cover plate at two ends, and the height of a layer is a cover plate
The height of block, then moves adjacent left cap plate or right cap plate to the end cover plate at two ends or by two ends
Inter panel moves to the initial position of centre, is rotated further by handwheel and is allowed to down or up one layer, and so operation is the most permissible
Left cap plate, right cap plate, middle cover plate are quickly opened or closed.
Work process of the present utility model is: the initial condition of whole mechanism is that cover plate 4 is laid on concrete tunnel 7,
When needing to overhaul the pipeline in concrete tunnel 7, first the top cover lath 5 of middle cover plate is taken out, then shake hands
Take turns and drive elevating lever 71 to make the end cover plate at two ends decline one layer by screw mechanism, then by adjacent left cap plate and
Right cap plate shifts left end and right-hand member end respectively onto, the most in triplicate, is just put well by the cover plate block all heaps down stacked, in
Between the wheel support 2 of four pieces of middle cover plates be folded in below middle cover plate (during cover plate tiling), then by hydraulic jack
The action bars on top carries out power by the installing hole on middle cover plate with hydraulic jack 3 and docks, manual operation hydraulic jack
Four pieces of middle cover plates are promoted by the action bars on top respectively, strut being folded in the wheel support 2 bottom middle cover plate so that it is
The roller of end contacts with track 10, and middle cover plate is shifted onto by the way of people tries hard to recommend an endlap in concrete tunnel 7
Put, owing to the length of wheel support 2 lengthens to centre successively from two ends so that middle cover plate can stack from level to level, weight
Multiple This move, until the left and right sides has six pieces of cover plate blocks respectively, wherein six pieces of cover plate blocks comprise two pieces of middle cover plates, this
Cover plate 4 just can quickly be opened by sample；After maintenance, shift the middle cover plate that both sides stack onto middle position,
Make hydraulic jack 3 rise, support whole middle cover plate, then wheel support 2 is folded into the end of middle cover plate
Portion, falls hydraulic jack 3, is laid by top cover lath 5, and such four pieces of middle cover plates just place；Then pass through
Shake handwheel makes the elevating lever 71 on screw mechanism rise one layer, and left cap plate or the right cap plate of stacking are passed through manpower
The mode pushed away shifts corresponding position onto, repeats This move, until all of cover plate block is all laid complete, thus achieves well
The quickly opening and closing of cover plate.
Surface vegetation (or concrete road surface) is fabricated to Pork-pieces cover plate block by this utility model, is laid in the upper of pipeline
Side, when need repairing pipeline time, just very easily one piece of block cover plate block can be stacked up by this utility model, overhaul complete
After, then tiling builds, and just can recover surface vegetation or concrete road surface, the whole work process used time is greatly shortened, and significantly
Reducing maintenance cost, be a kind of sustainable development, application prospect is huge.
