Retracted downward, piping lane well lid fall therewith；When well lid is rotated to fully closed position, latch 2 is contacted with well lid 3, latch 2
Lock tongue bottom is pressurized, and drives latch 2 to start to compress spring 7；Meanwhile hydraulic stem 5 drives well lid 3 to continue to close downwards, until inserting
Pin 2 is subject to the pushing tow pressure of spring 7 to act on, and is completely embedded into lockhole 12, and so far, well lid 3 has completely closed.
3rd, under dead electricity or fault condition, manual unlocking piping lane well lid：
Piping lane well lid in off position, has a power failure suddenly, causes hydraulic stem to open, at this time, can if people is stranded underground
To be directly manually pressed by 6 load releasing valve of hydraulic power unit, the hydraulic fluid pressure in 6 rod chamber of hydraulic power unit of releasing, so
Afterwards, drawstring 8 is dropped so that latch 2 is threaded off with piping lane cover seat of manhole 1, and enforcing piping lane well lid raises it.
4th, under dead electricity or fault condition, piping lane well lid is turned off manually：
Can be with manual unlocking load releasing valve, the hydraulic fluid pressure in 6 rodless cavity of hydraulic power unit of releasing, then manpower stir
Piping lane well lid, while under piping lane well lid gravity, piping lane well lid free-falling, piping lane well lid thereby turns off.
This piping lane Manhole cover assembly scope of application is very wide, saves manpower, conveniently opening and closing, intelligence degree height；In addition, this practicality
It is new have be automatically locked and opening device, locking is more solid and reliable, easy to open smooth；In order to promote the hair of smart city
Exhibition, urban pipe network piping lane well lid remote control monitoring can be accounted for as a chief component of smart city, the utility model
It is small with space, it is adapted to remote monitoring well lid hydraulic pump, realizes intellectualized operation, be greatly saved human cost.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on, should be included in the utility model
Protection domain within.
