Abstract
The utility model is a kind of novel combination type shield structure scraper, is applied to underground engineering field, belongs to shield machine accessory, forms primarily of scraper body, alloy body, wearing layer, bolt and the tool rest be fixed on cutter head panel.Described alloy body comprises master alloying body and primary alloy body; Described scraper body and tool rest are respectively equipped with and limit its degree of freedom and coordinate the groove and boss installed, and scraper body is bolted and is fixed on tool rest.Compared with prior art, a kind of novel combination type shield structure scraper of the present utility model, has that scientific structure design is reasonable, anti-wear performance is strong, the feature of strong shock resistance, effectively improves cutting-tool's used life.
Description
Technical field
The utility model relates to the shield cutter applied in a kind of underground construction, especially a kind of novel combination type shield structure scraper.
Background technology
The main operational principle of shield machine uses the cutter of shield machine head to advance along excavation limit, advance axis limit to form subterranean tunnel, and cutter, as one of the vitals of shield machine, mainly bears the excavation to soil or rock.When construction runs into the firm hard formation such as rock, sand-pebble, cutter can be subject to impacting accelerated wear test, and strong impact can make the relative position of cutter and tool rest change.If can not Timeliness coverage adjusting, will cause the failure modes such as alloy comes off, cutter hub eccentric wear, in long distance construction process, wearing and tearing be particularly serious, and this will affect the excavation progress in tunnel greatly.Therefore work out a kind of sound construction, anti-wear performance novel compositions shield structure scraper that is strong, strong shock resistance is extremely urgent.
Summary of the invention
The purpose of this utility model is that the deficiency existed for prior art provides a kind of novel combination type shield structure scraper, and this kind of shield structure scraper has that sound construction, anti-wear performance are strong, the feature of strong shock resistance.
The technical solution of the utility model is achieved in that a kind of novel combination type shield structure scraper, primarily of scraper body, alloy body, wearing layer, bolt and the tool rest composition be fixed on cutter head panel, scraper body is bolted and is fixed on tool rest, the scraper body back side is provided with positive stop lug boss, location and installation groove and detent, tool rest is provided with positive stop lug boss and clamping boss, in installation process, positive stop lug boss on tool rest is installed in the location and installation groove of scraper body, clamp boss coordinates in the detent be installed on scraper body simultaneously, further define the relative position relation of scraper body and tool rest.
A kind of novel combination type shield structure scraper of the present utility model, first instead of traditional shield structure scraper, shield structure scraper shock resistance is bad mostly at present, when running into harder stratum in work progress, scraper body and on alloy, wearing layer be first worn and impact, the bolt looseness that larger impact force can make cutter hub be connected with tool rest, and then cutter hub and tool rest can produce relative displacement.So not only can cause eccentric wear, also can accelerate the wearing and tearing of cutter, if adjust cutter not in time, alloy will be produced and come off or the failure mode such as cutter hub serious wear.The utility model, scraper body not only designs multiple installation counterbore, tool rest designs multiple bolt hole corresponding with cutter hub counterbore, and cutter hub and tool rest devise respectively two places with the use of groove and boss, cutter hub is undertaken fastening by bolt and tool rest.Based on this design, cutter hub is when being subject to impacting, tool rest just plays the effect of buffering and the change of relative position can not occur, compared with prior art, this utility model substantially increases cutting-tool's used life, thus improve the efficiency of shield-tunneling construction, this utility model have install firmly, anti-wear performance is good, the feature of strong shock resistance.
