On the outer wall in solidifying heatable adobe sleeping platform road 5.
The operation principle of the present invention is: the initial condition of whole mechanism is that cover plate is laid in coagulation
On heatable adobe sleeping platform road 5, when needing to overhaul the pipeline in concrete tunnel 5, first pass through artificial turning
Dynamic turning handle 112, turning handle 112 band moving sleeve 111 rotates, the rotation of sleeve 111
The rotation of nut 72, so that the nut 72 of screw mechanism declines, nut is driven by draw-in groove
72 drive elevating lever 71 to decline, and sink in concrete tunnel 5 by the end cover plate at two ends,
Then by manpower, middle cover plate is shifted onto one end stacking in concrete tunnel 5, stacks mode
For stacking to two ends respectively from centre so that cover plate block can stack from level to level, thus can be quick
Cover plate 1 is opened；After maintenance, by manually rotating backward turning handle 112,
The nut 72 in like manner making screw mechanism rises, and nut 72 drives elevating lever 71 to rise, point
The middle cover plate at two ends is not shifted onto initial position during corresponding closure state, repetitive operation
Several times, just middle cover plate all can be placed, thus can quick-make cover plate 1.
The present invention is installed in the underground work well of tubing, and its cover plate 1 can cover vegetation,
When tubing break down need maintenance time, only the cover plate 1 of this mechanism need to be stacked and open,
Workman enters and overhauls inside work well, is covered by cover plate 1 again, exempt from after having overhauled
Having gone to destroy road surface or the unnecessary trouble of road closure construction, maintenance cost declines the most accordingly, and
Can repeatedly open Guan Bi, sustainability is good, has a extensive future.
