Abstract
A kind of immersed tunnelling method tunnel winch type tube coupling Winch Pontoon downward putting device, steel plate, steel wire rope, fixing multiple sheave block, movable multiple sheave block, fixing gin block is separated including winch, niggerhead, steel plate is used to be divided into the left and right sides in the middle part of niggerhead, steel wire rope one end is fixed on niggerhead side, the other end is fixed on niggerhead opposite side through fixed block after fall block, start winch and reclaim remaining steel wire rope, activity multiple sheave block is connected with immersed tube tube coupling, it is again started up winch and tightens up steel wire rope, reach stress.Application this utility model can promote tube coupling sinking speed.
Description
Technical field
This utility model relates to a kind of immersed tunnelling method tunnel winch type tube coupling Winch Pontoon, is specifically related to a kind of immersed tunnelling method tunnel winch type tube coupling Winch Pontoon downward putting device.
Background technology
Tube coupling Winch Pontoon is the visual plant needed for immersed tunnelling method tunnel tube coupling sinking is installed, and mainly includes hull, downward putting device, electric power system, mooring system etc., and downward putting device therein is the core component of Winch Pontoon, is directly connected to the efficiency that tube coupling sinking is installed.
In prior art, there is slow-footed problem in winch type Winch Pontoon downward putting device in use.
Utility model content
The purpose of this utility model proposes a kind of immersed tunnelling method tunnel winch type tube coupling Winch Pontoon downward putting device for prior art deficiency, to accelerate tube coupling sinking installation rate.
The immersed tunnelling method tunnel winch type tube coupling Winch Pontoon downward putting device of a kind of improvement described in the utility model includes: winch, niggerhead separate steel plate, steel wire rope, fixing multiple sheave block, movable multiple sheave block, fixing gin block;Steel plate is used to be divided into the left and right sides in the middle part of niggerhead, steel wire rope one end is fixed on niggerhead side, the other end is fixed on niggerhead opposite side through fixed block after fall block, start winch and reclaim remaining steel wire rope, activity multiple sheave block is connected with immersed tube tube coupling, is again started up winch and tightens up steel wire rope, reach stress, winch pulling force is adjusted according to the negative buoyancy force of design during tube coupling sinking, and rope capacity should match with actual tube coupling sinking depth of water demand;Aggregate breaking force, after considering safety coefficient, should mate with winch pulling force;Owing to securing two of steel wire rope on niggerhead, therefore the overall linear velocity of steel wire rope is promoted to 2 times of winch linear velocity, and i.e. movable multiple sheave block and tube coupling sinking speed are all promoted to 2 times of prior art.
Preferably, described winch pulling force 200kN.
Preferably, it is circular that described niggerhead separates steel plate, thickness 20mm, and internal diameter matches with niggerhead external diameter, and external diameter matches with niggerhead two side shield, is positioned in the middle part of niggerhead, is connected with using welding manner between niggerhead.
Preferably, described steel wire rope is φ 26～φ 28 independent wire strand.
Preferably, described rope capacity is 500m.
Preferably, described fixing multiple sheave block, movable multiple sheave block are eight skating cars, and bearing capacity is 2000kN.
Preferably, described fixing gin block bearing capacity is 250kN.
This utility model beneficial effect: compared with prior art, its remarkable advantage is this utility model: tube coupling sinking speed can be promoted 1 times.
