Description
Technical field
This utility model relates to a kind of conveying worm blade, especially relates to a kind of detachable abrasion-resistance screw of shield machine
Conveyor blade.Belong to shield machine equipment technical field.
Background technology
Conveying worm is the important component part of earth pressure balanced shield, EPBS, and it is mainly used to cutterhead in shield gas-tight silo
The earth cut discharges shield body, keeps soil pressure in gas-tight silo simultaneously, maintains stablizing of the excavation face soil body.Shield machine is city
Visual plant in city's subway and construction of underground tunnel, along with the quickening of city process, its range is increasingly wider, in engineering
In construction, proportion is the most increasing, is now widely used in the Tunnel Engineering such as subway, railway, highway, municipal administration, water power.
Conveying worm is made up of helical axis, helical blade body, cylinder, driving means, gate of slagging tap, and is earth pressure balance
The soil-discharging device of shield, the earth that cutterhead is scaled off by it is while keeping soil pressure, by automatic for the soil pressure value in soil storehouse and spiral shell
Rotation tachometer value compares, it is achieved continuous print dynamic earth pressure balance process, it is ensured that the soil body in shield soil storehouse is discharged continuously out
Normally tunnel forward.Owing to spiral blade of spiral conveyer is chronically at high load capacity stone soil delivery state, wear working condition is serious, time
Often occurring that helical blade serious wear is shut down to repair to ensure work anti-wear performance, conventional shield conveying worm blade is adopted more
It is used in body blade to meet charge level side and carry out manual hardfacing or use the blade of cast structure to be installed on body helical blade
Make product have more preferable anti-wear performance etc. method, but effect is unsatisfactory, still cause maintenance rate to raise, project progress
The drawbacks such as delay.
Summary of the invention
This utility model is contemplated to solve above-mentioned technical problem, and a kind of raising conveying worm blade provided is wear-resisting
Performance, effectively reduces maintenance rate, reduces maintenance cost, effectively extends the shield machine in conveying worm blade service life with removable
Unload abrasion-resistance screw conveyor blade.
The technical solution adopted in the utility model is: shield machine is with detachable abrasion-resistance screw conveyor blade, and structure is as follows:
The wear-resisting cambered plate suitable with conveyor blade body radian and size, its upper end sidewall is fixed with the edge that radian is suitable
Backplate, wear-resisting cambered plate and backplate junction, edge heap be welded with suitable with both sizes anticorrosive and wear-resistant alloy-layer,
Wear-resisting cambered plate and conveyor blade body are at least connected by 2 dormant bolts.
Described wear-resisting cambered plate and edge backplate are bimetal composite wear resistant plate and make.
Described bimetal composite wear resistant plate is to be combined certain thickness at the outer surface of ordinary low-carbon steel or low-alloy steel
Wear-resistant alloy layer make.
This utility model has the advantage that owing to using said structure
On helical blade body, repeatedly carry out the inconvenience repairing overlay-operation when 1, solving maintenance in the past overhaul with manpower
The increase of cost.
2, the blade wear performance of cast structure is insufficient for work condition environment, bimetal composite wear resistant material abrasiveness
Can be excellent, being actually needed of operating mode can be met.
This utility model is enterprise's saving great amount of cost, and improves the anti-wear performance of conveyor blade body, extends defeated
Send the service life of machine blade body, effectively reduce maintenance rate, reduce maintenance cost, there is preferable promotional value.
Accompanying drawing explanation
Fig. 1 is that structural representation is cutd open in side of the present utility model；
Fig. 2 is that the K of this utility model Fig. 1 is to structural representation.
In figure: edge backplate 1, anticorrosive and wear-resistant alloy-layer 2, wear-resisting cambered plate 3, conveyor blade body 4.
Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is described in further detail, but protection of the present utility model
Scope is not limited by specific embodiment institute, is as the criterion with claims.It addition, with without prejudice to technical solutions of the utility model
Under premise, any change or change that the those of ordinary skill in the art being made this utility model easily realize fall within this
Within the right of utility model.
Embodiment 1
This utility model shield machine as shown in Figure 1, 2 is with detachable abrasion-resistance screw conveyor blade, and structure is following with defeated
Sending machine blade body 4 radian and the suitable wear-resisting cambered plate 3 of size, the edge that its upper end sidewall is fixed with radian suitable protects
Plate 1, wear-resisting cambered plate 3 and edge backplate 1 junction heap are welded with suitable with both sizes anticorrosive and wear-resistant alloy-layer
2, wear-resisting cambered plate 3 is connected by 6 dormant bolts with conveyor blade body 4.Described wear-resisting cambered plate 3 is combined for bimetallic
Wearing plate is made.Can suppress or pull into the helical form cambered surface of certain size, mold arc according to the mode such as mold or chain block
Face shape keeps consistent, to ensure that wear-resisting cambered plate 3 is installed with conveyor blade body 4 with conveyor blade body 4 radian value
Laminating degree；Edge backplate 1 is also made for bimetal composite wear resistant plate, is pressed into certain radius value with veneer reeling machine or forcing press
Arc, its inner arc radius size is consistent with wear-resisting cambered plate 3 outer shroud radius value；Wear-resisting cambered plate 3 and edge backplate 1 welding,
