Description
Technical field
Slurry shield machine mud door field is the utility model is related to, specifically a kind of gas cushion type mud water shield machine mud door
Device for preventing leakage.
Background technology
Mud storehouse is divided into muddy water storehouse and air cushion storehouse by gas cushion type mud water shield machine by a bearing plate, and by controlling air cushion
The air pressure in storehouse carrys out the mud pressure in indirect control muddy water storehouse, forces Water And Earth Pressures of the muddy water storehouse mud balance from face.Mud
Slurry door is located at the bottom of bearing plate, and its switch motion directly determines whether connecting for mud storehouse and air cushion storehouse.
In normal driving, mud door is in open mode, and muddy water storehouse is full of the mud with certain pressure.When needing to enter
When air cushion storehouse carries out upkeep operation, routine operation is：Mud door is closed, the pressure bladder for being articulated with mud door is filled by valve
Gas, makes air bag be adjacent to bearing plate, cut-off and the connection in muddy water storehouse, then reduces air cushion storehouse pressure, and scheduling job personnel's normal pressure enters
Storehouse.As can be seen here, the reliability that mud door seals after closing is most important, and the safety for directly affecting operating personnel and maintenance are made
The smooth implementation of industry.
In slurry shield tunneling process, muddy water storehouse working environment is severe, and pressure bladder is frequently subjected to solid in mud
The abrasion of grain, situation severe patient even directly result in airbag fails.How reasonably to be selected for the different situation of pressure bladder
A kind of sealing of leakage preventing device to mud door is most important.
Utility model content
The defects of goal of the invention of the present utility model is to overcome described in background technology, so as to realize that one kind can be directed to
The different situations of various pressure bladders, by adjusting fastener, effectively prevent the gas cushion type mud water shield machine of mud door leakage
The device for preventing leakage of mud door.
For achieving the above object, the technical solution of the utility model is：A kind of gas cushion type mud water shield machine mud door
Device for preventing leakage, including isolation door-plate, pressure bladder, connecting plate and fastener, the connecting plate fixed by fastener and set
Be placed in the both sides of gas cushion type mud water shield machine bearing plate, elastic fastener can adjust between isolation door-plate and bearing plate away from
From；The isolation door-plate is close to bearing plate setting, and the width for isolating door-plate is more than the width of mud door opening on bearing plate, and isolates
Door-plate both sides are provided with the slideway for isolating door-plate slip between bearing plate and connecting plate, between connecting plate and bearing plate, hold
It is hinged between pressing plate and isolation door-plate and is provided with drive mechanism, isolation door-plate is glided by the drive of drive mechanism on slideway
It is dynamic；The isolation door-plate plate face both sides for being close to bearing plate offer air bag groove, and pressure bladder is set in air bag groove.
As optimal technical scheme of the present utility model, the drive mechanism is hydraulic cylinder, and engineering is to realize liquid in practice
The Synchronization Control of cylinder pressure, hydraulic cylinder is arranged to two, and hydraulic cylinder generally relates to isolation door-plate axis and is symmetrical arranged.
As optimal technical scheme of the present utility model, the fastener is bolt and nut fastening structure.
The device for preventing leakage of gas cushion type mud water shield machine mud door of the present utility model, in the closing of isolation door-plate, blanket gas
After capsule inflation, tightening fastener parts, reduce the gap for isolating door-plate and bearing plate, in the case where pressure bladder is without state of wear, Neng Gouyou
Effect reduces the contact area of pressure bladder and bearing plate, while reduces the side force between pressure bladder and bearing plate；Close
Seal under air bag state of wear, tightening fastener parts, force pressure bladder to be adjacent to bearing plate, ensure sealing effectiveness；It is close under emergency
After sealing airbag fails, tightening fastener parts, isolation door-plate is set to be reduced as much as possible with pressure-bearing sheet separation, mud door front portion heap accumulated slag
Soil, sealing effectiveness can still be ensured.
The beneficial effect of the device for preventing leakage of gas cushion type mud water shield machine mud door of the present utility model：
The device for preventing leakage of gas cushion type mud water shield machine mud door of the present utility model, it is easy to operate, it is economical and practical,
The different situations of various pressure bladders can be directed to, by adjusting fastener, effectively prevent the leakage of mud door.The utility model
It is easy to operate, quick, economical and practical.
