Firmly, port lid is opened during inspecting state, maintenance cage is hung in and is overhauled, in order to reduce the loss of flood peak, maintenance bore dia is as far as possible small.
The platform of two wing types is devised on maintenance cage for this, is arranged symmetrically, when passing in and out manhole, is packed up platform, subtract as far as possible
Small cage appearance and size, after manhole enters vertical shaft, put down platform and lock, the size of platform matches with vertical shaft.Overhaul people
Member can be overhauled by the platform of wing type to shaft wall.The platform of two wing types is connected by slew gear and hanging basket
Connect, platform can flexibly rotate around hanging basket.
Accompanying drawing 1 is visible：Cage is overhauled mainly by hanging basket（Part 1）, platform（Part 4）, slew gear（Part 3）, equalizer bar（Part
5）, hanging beam（Part 6）Movable railing（Part 2）Several parts form
Accompanying drawing 1 be cage by manhole after, put down the wing-shaped platforms of both sides（Part 4）And the state locked, install
Movable railing（Part 2）, personnel can be into platform to shaft wall progress repair and maintenance.In order to be overhauled to whole shaft wall
Safeguard, be provided with slew gear（Part 3）, slew gear is mainly made up of upper undersetting and pivoting support, can bear enough axles
To power and tilting moment.By slew gear, platform can rotate around hanging basket and hang indigo plant（Part 1）Pass through equalizer bar（Part 5）, hanging beam（Part
6）It is connected with rigging, equalizer bar（Part 5）With hanging beam（Part 6）Between be provided with horizontal thrust bearing, ensure that platform rotates around hanging basket
When do not drive hanging beam（Part 6）Rotation, the mutual winding interference of two hawsers will not be caused.Vertical shaft service work is completed, passes through inspection
When repairing hole, it is necessary to pack up platform, Fig. 3 is the state that platform is collapsing.
Cage is overhauled using high pressure vertical shaft, vertical shaft manhole bore size can be minimized, reduces the loss of flood peak,
Meet the needs of service shaft well simultaneously.
