Abstract
The invention discloses a diversion cutter for a shield machine. The cutter consists of a base (1) and an alloy body (2), wherein the bottom surface of the base (1) is welded at a front position between two radial adjacent scrapers (4) on a spoke of a cutter head (3); and the base (1) has a frustum shape of which the front is narrow and low and the back is wide and high. The cutter has the advantages of effectively protecting the cutter head, prolonging the service life of the cutter head, increasing the warehousing speed of residue soil, reducing the adhesion of the residue soil and improving construction efficiency, along with simple structure and convenient use.
Description
Technical field
The present invention relates to constructing tunnel shield machine parts, relate in particular to a kind of shield machine diversion cutter.
Background technology
Shield machine is a kind of special engineering machinery of tunnel piercing.The critical piece of shield machine front portion is: the forefront is a cutterhead, and there are anterior shield otch ring and Tu Cang etc. in the back of cutterhead.Scraper, hobboing cutter, multiple cutter such as cutter in advance are installed on the cutterhead, and perforate forms slag inlet on the cutterhead.
During work, under the rotation of cutterhead drives, be installed in hobboing cutter on the cutterhead, cutter is finished the excavation cutting to the soil body in advance; Scraper rake face on the cutterhead spoke then head-on contacts with the soil body in the place ahead it is scraped, and makes it enter the cutterhead slag inlet in scraper the place ahead, enters in the native storehouse again.
The soil body that cuts forms dregs, in entering the flow process of slag inlet, dregs will produce a series of harmful effects to cutterhead: one, because dregs is in a kind of natural flow condition, the part dregs flows to the space between two scrapers, fail to flow to the scraper position, scraper scrape less than, influence the speed that dregs enters Tu Cang, thereby reduced driving speed.Two, the dregs that flows away from space between the scraper in flow process, will produce the cutterhead at scraper rear and impact and wearing and tearing, thereby influence the life-span of cutterhead.Three,, deposit easily and be bonded to mud cake, thereby in native storehouse, pile up, be difficult to discharge, thereby influence the driving speed and the construction safety of shield machine without the dregs of scraper scraping.
Summary of the invention
Purpose of the present invention just provides a kind of shield machine diversion cutter, and it can effectively protect cutterhead, improves the life-span of cutterhead; Improve the speed of putting in storage of dregs, reduce the bonding of dregs, improve efficiency of construction; And it is simple in structure, and is easy to use.
The present invention realizes its goal of the invention, and the technical scheme that is adopted is:
A kind of shield machine diversion cutter, its design feature is: be made of pedestal and alloy body, described base bottom surface is welded on the centre position, two scraper the place aheads of radially adjoining on the cutterhead spoke; Pedestal is beloid and low early and high after frustum, and the top of pedestal has groove, welding alloy body in the groove, and alloy body end face and side slightly exceed pedestal.
Compared with prior art, the invention has the beneficial effects as follows:
During the cutter head of shield machine rotation, hobboing cutter, in advance cutter cuts the dregs that gets off, cutterhead moves in a circle relatively, because the centre position in two scraper the place aheads of radially adjoining is provided with low early and high after, pre-small post-large diversion cutter, thereby being subjected to diversion cutter, the dregs in two scraper gap dead aheads stops and dredge, the flow path of this part dregs changes to inside and outside both sides, make it just in time flow to the scraper position, this part dregs also enters Tu Cang through the scraping of scraper, the scraping action of scraper is fully reflected, improve the speed that dregs enters Tu Cang, improved driving speed; Reduced simultaneously to leak and scraped impact and the wearing and tearing of dregs, prolonged the application life of cutterhead scraper rear cutterhead; And the flow path of dregs changes, and reduces the caking property of dregs, makes it be difficult for piling up in native storehouse, easier discharge, thus improve efficiency of construction.And diversion cutter of the present invention is simple in structure, and is easy to install, do not need existing shield machine is done any change.
The top of above-mentioned pedestal has groove, welding alloy body in the groove, and alloy body end face and side slightly exceed pedestal.
Like this, dregs main with diversion cutter in high rigidity, the alloy body of high-wearing feature come in contact, rub, can improve the application life of diversion cutter, also can more effectively play dregs roll, the effect of fragmentation, further improve the flowability of dregs, help it and put in storage fast and discharge.
The Breadth Maximum of above-mentioned pedestal is equal to or greater than the gap width between two scrapers of radially adjoining, and the pedestal axis equates with the distance at the center to center distance cutterhead center of described two scraper gaps apart from the distance at cutterhead center.
Like this, can better guarantee equal can the stopping, dredge to doctor position and, further improved the water conservancy diversion effect of diversion cutter by diversed cutter of dregs in two scraper gap the place aheads by scraping.
The alloy body of welding is one or more alloy body piece in the groove of pedestal.
Welding polylith alloy body can reduce cost than the monoblock alloy body.
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Fig. 2 is the A-A generalized section of Fig. 1.
The specific embodiment
Embodiment
Fig. 1, Fig. 2 illustrate, and a kind of specific embodiment of the present invention is, a kind of shield machine diversion cutter is made of pedestal 1 and alloy body 2, and described pedestal 1 bottom surface is welded on the centre position, two scraper 4 the place aheads of radially adjoining on cutterhead 3 spokes; The frustum that pedestal 1 is beloid and low early and high after (be that pedestal is narrower lower from the farther position of scraper, the position of more close scraper is wideer higher).
Fig. 1, Fig. 2 also illustrate, and the top of pedestal 1 has groove in this example, welding alloy body 2 in the groove, and alloy body 2 end faces and side slightly exceed pedestal 1.The Breadth Maximum of pedestal 1 is equal to or greater than the gap width between two scrapers 4 of radially adjoining, and pedestal 1 axis equates with the distance at center to center distance cutterhead 3 centers in described two scrapers 4 gaps apart from the distance at cutterhead 3 centers.The alloy body 2 of welding is one or more alloy body 2 in the groove of pedestal 1.
Shield machine is when work, and the cutterhead forward and backward is rotation alternately, and the both sides on the cutterhead 3 same spokes are arranged with two row's scrapers 4 back-to-back; Corresponding to this two rows scraper 4, diversion cutter 1 of the present invention also has back-to-back two rows of (being that near-end is relative with near-end).
