Abstract
The invention discloses a replaceable mixing pile for a shield tunneling machine. The replaceable mixing pile for the shield tunneling machine mainly comprises a tool bit, a knife rest, a bolt, a movable block, a cutter shaft and a reinforcing sleeve, wherein the replaceable mixing pile can be arranged inside a hob cutter box of a cutter head of the shield tunneling machine in a breech-loading manner; the cutter head is welded on the top surface of the knife rest; the cutter shaft is fixed on the plane of the knife rest through the reinforcing sleeve; the movable block is connected to the side of the knife rest through a bolt, and the entire mixing pile is fixed inside the hob cutter box in a radial direction by the movable block. The replaceable mixing pile for the shield tunneling machine can be convenient to replace, and is also capable of replacing a hob to cut sand, and agitating the sand inside a pressure bin. Meanwhile, the space is saved; flow of the sand inside the pressure bin is facilitated, and the cut sand inside the pressure bin can be effectively prevented from being adhered to or fixedly connected to the wall of the bin.
Description
Technical field
The present invention relates to the rabbling mechanism of shield machine pressure storehouse inner additive in the shield machine industry, is a kind of brand-new shield machine changeable type agitation pile.
Background technology
Shield machine belongs to the easy-abrasion part of shield machine rabbling mechanism with agitation pile, be installed on the rotating cutter-head of shield machine.The effect of agitation pile is the rotation by cutterhead, and the native sand that knife cutting in the pressure storehouse is got off stirs, breaks into pieces, prevents that the cutting soil sand in the pressure storehouse from adhering to and being cemented on the bulkhead, then is transported to shield machine main body back by conveying worm.At present the used agitation pile of shield machine is to be fixed on the cutterhead by the cutterhead front with bolt, in the underground construction process, in case agitation pile serious wear or come off, with non-exchange, so it is extremely urgent to work out the changeable type agitation pile.
Summary of the invention
The object of the present invention is to provide a kind ofly be easy to change, fixing reliably, more wear-resisting, joint space-efficient shield machine changeable type agitation pile, with the solution defective that agitation pile can't be changed in the underground construction process.
The present invention is achieved in that
Shield machine changeable type agitation pile mainly is comprised of cutter head (1), knife rest (2), bolt (3), loose piece (4), cutter shaft (5), reinforcing sleeve (6).It is characterized by, cutter head (1) is welded on the knife rest (2), cutter shaft (5) is fixed on the knife rest (2) by reinforcing sleeve (6), loose piece (4) is connected on the knife rest (2) by bolt (3), the part interval of exposing girff at knife rest (2) spreads the thick wearing layer of weldering 3-5mm, strengthens the anti-wear performance of agitation pile.The operating principle of this agitation pile is, in agitation pile employing back loading type is packed the hobboing cutter girff behind into from cutterhead.Cutter head (1) working depth is consistent with hobboing cutter, and along with the rotation of cutterhead, cutter head moves in a circle around the cutterhead center, cuts native sand.The part that knife rest (2) stretches out girff is exposed in the pressure storehouse, and along with the rotation of cutterhead, the native sand that knife cutting is got off stirs, breaks into pieces, prevents that the cutting soil sand in the pressure storehouse from adhering to and being cemented on the bulkhead.
The present invention compares with existing agitation pile, and adopting this kind shield machine is to pack in the cutterhead with back loading type with changeable type agitation pile advantage.Can conveniently change when the agitation pile wearing and tearing or after scrapping; Soldering has carbide alloy on the cutter head, can be at the native sand of excavation face cutting; The agitation pile knife rest partly exposes in the pressure storehouse, can the native sand that cut be stirred, break into pieces; The knife rest exposed part is welded with latticed wearing layer, has strengthened anti-wear performance; Because this kind agitation pile is contained in the hobboing cutter girff, has saved the space, is conducive to native sand and in the pressure storehouse, flows.
Description of drawings
Fig. 1 is structure side view of the present invention;
Fig. 2 is structural front view of the present invention;
(1) is cutter head in the accompanying drawing, and (2) are knife rest, and (3) are bolt, and (4) are loose piece, and (5) are cutter shaft, and (6) are reinforcing sleeve.
The specific embodiment
With reference to accompanying drawing, a kind of shield machine changeable type agitation pile is installed on the rotating cutter-head, mainly comprises cutter head (1), knife rest (2), bolt (3), loose piece (4), cutter shaft (5), reinforcing sleeve (6).Main feature is that the present invention adopts back of the body dress mode to be installed in the hobboing cutter girff from the cutterhead back, replaces original hobboing cutter.When bolt (3) tightens gradually, loose piece (4) installed surface will be progressively near the girff installed surface, the most at last with the girff installed surface paste dead, thereby reach fixing diametrically purpose.The operating principle of this agitation pile is, in agitation pile employing back loading type is packed the hobboing cutter girff behind into from cutterhead.Cutter head (1) working depth is consistent with hobboing cutter, and along with the rotation of cutterhead, cutter head moves in a circle around the cutterhead center, cuts native sand.The part that knife rest (2) stretches out girff is exposed in the pressure storehouse, and along with the rotation of cutterhead, the native sand that knife cutting is got off stirs, breaks into pieces, prevents that the cutting soil sand in the pressure storehouse from adhering to and being cemented on the bulkhead.
Claims (3)
1. shield machine changeable type agitation pile, mainly formed by cutter head (1), knife rest (2), bolt (3), loose piece (4), cutter shaft (5), reinforcing sleeve (6), it is characterized by, cutter head (1) is welded on the knife rest (2), cutter shaft (5) is fixed on the knife rest (2) by reinforcing sleeve (6), loose piece (4) is connected on the knife rest (2) by bolt (3), and the part interval of exposing girff at knife rest (2) spreads the thick wearing layer of weldering 3-5mm, strengthens the anti-wear performance of agitation pile.
2. shield machine according to claim 1 changeable type agitation pile, it is characterized in that: the operating principle of described agitation pile is, agitation pile is installed on the cutterhead, during the cutterhead rotation, agitation pile moves in a circle around the cutterhead center, and cutter head cuts native sand in excavation face, and the knife rest afterbody stirs, breaks into pieces the native sand under the cutting in the pressure storehouse, strengthen the flowability of native sand, prevent that native sand from adhering to and being cemented on the bulkhead.
3. shield machine according to claim 1 changeable type agitation pile is characterized in that: the method for work of described agitation pile is, adopts rear installed that agitation pile is installed in the cutterhead hobboing cutter girff, with the mounting means of hobboing cutter cutter shaft is fixed in the girff; By bolt loose piece is connected on the knife rest, bolt tightens gradually, the loose piece installed surface will be progressively near the girff installed surface, the most at last with the girff installed surface paste dead, thereby reach diametrically the fixedly purpose of agitation pile; When cutterhead rotated, agitation pile can move in a circle around the cutterhead center, thereby performance is cut, stirring action.
