Abstract
Disclose a wear-resisting shield constructs cutter with dual blade, it comprises handle of a knife, main position sword, inferior position sword and wedge supporting shoe, inferior position sword is fixed on the handle of a knife, main position knife cover is put and is fixed in inferior position sword outside, the rear portion at the handle of a knife is fixed to the wedge supporting shoe, and is supporting the trailing edge of main position sword. The utility model discloses possessed the self-repair function, had long service life's advantage, avoided artifical difficulty and the risk of changing the cutter, guaranteed the normal tunnelling speed that the shield constructs, more can adapt to the construction in extra long distance tunnel.
Description
Technical field
The utility model relates to a kind of shield machine accessory, is specifically related to a kind of wear-resisting shield cutter of dual cutting edge that has, and belongs to construction engineering technical field.
Background technology
The groundwork principle of shield machine is to advance while excavating with the formation subterranean tunnel along the axis that advances at the cutter of underground utilization shield machine head, and cutter is mainly born the excavation to soil or rock as one of vitals of shield machine.When running into firm hard formations such as rock, sand-pebble when construction; Cutter meeting accelerated wear test; Especially extra long distance construction, the wearing and tearing of shield machine cutter are particularly severe, therefore in the whole process of driving, certainly will will change cutter; But difficulty and the risk of changing cutter in construction midway are very big, also influence the excavation progress in tunnel in addition.
Present conventional method is to be fixed on cutting tip on the blade holder with screw, in case tool wear is serious, then changes from behind.But this needs manual work to judge, manual work is changed, and exists certain risk and influences excavation speed.
The utility model content
The purpose of the utility model is that the existing common shield machine of solution is not wear-resistant with cutter; The technical problem that application life is not long; A kind of wear-resisting shield cutter of dual cutting edge that has is provided; It adopts reviews one's lessons by oneself duplex, reaches the effect that increases the service life, the difficulty of avoiding constructing and changing cutter midway and caused.
For achieving the above object, the scheme that its technical problem of the utility model solution is taked is following:
A kind of have a wear-resisting shield cutter of dual cutting edge; It is made up of handle of a knife, status of a sovereign cutter, inferior position cutter and wedge shape back-up block; Said time the position cutter is fixed on the handle of a knife; Time cutter outside, position is put and be fixed on to said status of a sovereign broach shell, and said wedge shape back-up block is fixed on the rear portion of handle of a knife, and is supporting the trailing edge of said status of a sovereign cutter.
The utility model is described to have the wear-resisting shield cutter of dual cutting edge, and next cutter is provided with groove, and said status of a sovereign cutter is provided with fin, and this fin is embedded in the said groove; Said status of a sovereign cutter passes through screw on the cutter of said inferior position; Said status of a sovereign cutter has hard alloy cutter bit with time position cutter.
The beneficial effect of the utility model is; Bear cutwork by being in the outer field status of a sovereign cutter during initial the driving; When status of a sovereign cutter may wear to when to a certain degree exposing time the position cutter, the residue fragment of this status of a sovereign cutter just separates and comes off automatically to both sides, proceeds cutting and excavates thereby expose a time position cutter.Structure by this, the utility model just can be used the longer time with cutter than existing common shield machine, and in the cutting mining process, do not need manual work to judge whether cutter weares and teares, and also needn't artificially change cutter midway.So said have the wear-resisting shield cutter of dual cutting edge and possessed the self-regeneration function, has the advantage of long service life, avoided the difficulty and the risk of artificial replacing cutter, guaranteed the normal driving speed of shield structure, more can adapt to the construction in extra long distance tunnel.
Description of drawings
Fig. 1 is the overall structure figure of the utility model.
Fig. 2 is the state diagram after the utility model wearing and tearing.
Fig. 3 is the utility model status of a sovereign cutter falling-off effect figure.
Fig. 4 is the utility model time position cutter working state figure.
The practical implementation method
Below in conjunction with accompanying drawing the utility model is done a detailed description.
As shown in Figure 1, said have the wear-resisting shield cutter of dual cutting edge and be made up of handle of a knife 1, status of a sovereign cutter 2, inferior position cutter 3 and wedge shape back-up block 4.Said time position cutter 3 is weldingly fixed on the handle of a knife 1, and the front and rear portions of this time position cutter 3 is provided with horizontal groove 5.Said status of a sovereign cutter 2 is placed on time outside of position cutter 3, and its front and rear portions is provided with fin, and this fin is embedded in the groove 5 of said position cutter 3, so that the location; This status of a sovereign cutter 2 is fixed on the cutter 3 of said inferior position through screw 6.Said status of a sovereign cutter 2 all has hard alloy cutter bit 2.1 and 3.1 with time position cutter 3.Said wedge shape back-up block 4 is weldingly fixed on the rear portion of handle of a knife 1, and is supporting the trailing edge of said status of a sovereign cutter 2, supports protective effect to rise, and makes status of a sovereign cutter 2 cause infringement with time position cutter 3 unlikely mutual friction mutually in working angles simultaneously.
The utility model is in the driving of shield machine; Play a leading role by status of a sovereign cutter 2 when beginning to tunnel usually, after certain long distance is excavated in 2 cuttings of status of a sovereign cutter, can produce certain wearing and tearing; But when status of a sovereign cutter 2 may wear to the point of a knife that exposes time position cutter 3; See shown in Figure 2ly, the separation that can come off from the trend both sides of the fragment of status of a sovereign cutter 2 is referring to shown in Figure 3.After status of a sovereign cutter 2 came off, the cutter (referring to Fig. 4) of inferior position cutter 3 and handle of a knife 1 Automatic Combined Cheng Xin was proceeded cutting by inferior position cutter 3 and is excavated.
