Two ends lengthen successively so that middle cover plate can stack from level to level；The all of cover plate block in right side is complete by identical operating process
Become, after maintenance, position that middle cover plate is shifted onto tile accordingly, make rhombus elevating mechanism 2 rise, then will wheel
Son supports 5 bottoms folding into cover plate block, changes the direction of rotation of external drive mechanism, so that the spiral shell of rhombus elevating mechanism 2
Mother 22 is to the right or moves in left side, and rhombus bridge 23 folds, and falls rhombus elevating mechanism 2, is finally laid by top end cover lath 9
, then short track 4 is taken out, rotates turning handle 112 in opposite direction, make the elevating lever 71 on leading screw 74 rise to
Suitably position, shifts left cap plate or right cap plate onto correct position, finally end cover plate is risen to suitable position
Put.
Surface vegetation (or concrete road surface) is fabricated to cover plate block one by one by this utility model, is laid in the upper of pipeline
Side, when need repairing pipeline time, just easily cover plate block one by one can be stacked up by this utility model, overhaul complete
After, then tiling builds, thus recover surface vegetation or the concrete road surface whole work process used time is greatly shortened, and significantly drop
Low maintenance cost, is a kind of sustainable development, and application prospect is huge.
