Abstract
The utility model provides a kind of reinforced welded shield alloy scraper cutter; including scraper body, knife beam, the carbide chip positioned at scraper body end; wire netting and silver-bearing copper weld tabs are provided between the scraper body and carbide chip; scraper body surface is provided with wearing layer; scraper body is fixedly installed on scraper tool apron; scraper tool apron is arranged on knife beam both sides, and knife beam top is provided with scraper Anti-bumping protection block, is supported between scraper tool apron and knife beam provided with scraper.In brazing process, by increasing layer of metal net between alloy cutter hub and carbide chip, silver-bearing copper weld tabs is set to be evenly distributed between alloy cutter hub and carbide chip after melting, substantially increase soldering strength, being prevented effectively from weld seam after soldering has slag inclusion crackle, the replacing number of times of shield machine cutter is reduced, and then reduces construction cost, operating efficiency is improved.
Description
Technical field
A kind of shield cutter technical field that the utility model belongs in underground engineering application, and in particular to reinforced welded
Shield alloy scraper cutter.
Background technology
In underground engineering field, the application of shield construction is more and more extensive.Shield machine in underground engineering is bulky,
Weight is big, and underground activities space is limited, and cutter head of shield machine rotation drives excavation of the various cutters completions to the soil body thereon during work.
Shield cutter, cutter be directly with landwaste, the part of rock contact, it is easy to wear and need in time change.The cutter of shield machine point
For hobboing cutter and alloy cutter, alloy cutter is divided into scraper, cutting knife, center fish tail knife and dual-pilot cutter etc. again.Wherein, alloy cutter
Brazing quality directly influences the quality of alloy cutter again, while having influence on the cutting effect and driving speed of shield machine.This is just
It is required that shield alloy cutter will have very high welding quality.
The problem of traditional shield machine alloy cutter reflects in brazing process be：Alloy cutter hub passes through with hard alloy
The direct soldering of silver-bearing copper weld tabs, fracture, weld seam, which easily occurs, in hard alloy after soldering has what slag inclusion crackle, brazing alloy integrally came off to show
As, so as to need the frequently shield machine alloy cutter that more renews, expend a large amount of manpowers, financial resources and material resources, cause use cost compared with
It is high.Therefore, in the urgent need to developing a kind of reinforced welded shield alloy cutter.
Existing scraper cutter does not have ballistic support, and rock has certain percussion to cutter hub, and cutter is often damaged,
Change frequent.
Utility model content
In order to tackle the problem at its root, the utility model according to the soldering principle analysis of shield machine alloy cutter there is provided
A kind of reinforced welded shield alloy scraper cutter, solving weld seam after soldering has slag inclusion crackle, brazing alloy integrally to come off
Phenomenon, improves weld strength.
To achieve the above object, the utility model is adopted the following technical scheme that：A kind of reinforced welded shield alloy scraper
Cutter, including scraper body, knife beam, the carbide chip positioned at scraper body end, the scraper body and hard alloy
Wire netting and silver-bearing copper weld tabs are provided between blade, scraper body surface is provided with wearing layer, and scraper body is fixedly installed on scraper knife
On seat, scraper tool apron is arranged on knife beam both sides, and knife beam top is provided with scraper Anti-bumping protection block, is provided between scraper tool apron and knife beam
Scraper is supported.
The scraper body is fixed on scraper tool apron by attachment bolt.
The wire netting is metal mesh sheet, and metal mesh sheet is 40-80 mesh, and metal mesh sheet thickness is 0.1-0.3mm.
The wire netting is the metal mesh sheet that fusing point is higher than silver-bearing copper weld tabs.
The carbide chip is tungsten-carbide inserts.
Scraper supports the inclination angle that 0-45 degree is provided between knife beam.
The beneficial effects of the utility model are：In brazing process, by between alloy cutter hub and carbide chip
Increase layer of metal net, silver-bearing copper weld tabs is evenly distributed between alloy cutter hub and carbide chip after melting, greatly
Soldering strength is improved greatly, being prevented effectively from weld seam after soldering has slag inclusion crackle, reduce the replacing number of times of shield machine cutter, and then
Construction cost is reduced, operating efficiency is improved.
Scraper Anti-bumping protection block can be arranged on knife beam by way of welding or bolt-connection, can increase shield
The rigidity of structure machine knife beam and the wearability on surface, scraper Anti-bumping protection block can also effectively prevent biotite gneiss to scraper body
Percussion.
Scraper support can make sillar and dregs under being cut during driving can effectively to scraper tool apron formation supporting role
Supported along scraper into storehouse of burying, to sillar and dregs formation guide effect.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in figure 1, a kind of reinforced welded shield alloy scraper cutter, including scraper body 4, knife beam 9, positioned at scraper
