The utility model discloses can effectively solve the problem of the excessive wear of sword hub, have advantages such as with low costs, simple structure, simple operation.
Description
Technical field
This utility model is related to shield machine cutting-tool engineering field, it particularly relates to a kind of wear-resisting type shield machine roller cutter
Girff device.
Background technology
Shield tunnel driving technology has gone up the history of a century, and the fast development through nearly half a century becomes day by day
Ripe.In underground engineering construction at home and abroad, shield method with its safety, high-quality, efficiently, environmental protection, the low advantage of labor intensity exist
The engineering such as Urban Underground track traffic and underground utilities is widely used.During shield driving, its front end cutterhead rotation digging
Ground layer soil body, cutterhead is configured with different types of cutter, is broadly divided into hydraulic pressure class cutter: dish type, button, wedge tooth etc.；Cutting
Class stage property: cutting knife, serrated knife, scraper, knife of backbreaking etc..When tunneling in the earth formation, rolled using the disk cutter being arranged on cutterhead
Produce the purpose to reach fractured rock for the effect that impact crushing and shearing are pulverized, hobboing cutter whether can normal work, directly affect
To shield machine cutting effect, be unearthed situation and driving speed.Due to the rotation of cutterhead, the rubble in muddy water cabin can wear and tear knife
Hub, knife hub excessive wear then can affect the normal work of cutter.
Utility model content
The purpose of this utility model is to provide a kind of wear-resisting type shield machine roller cutter girff device, to overcome currently available technology
Above shortcomings.
For realizing above-mentioned technical purpose, the technical solution of the utility model is achieved in that
A kind of wear-resisting type shield machine roller cutter girff device, including girff and the cutter shaft being located in girff, on described cutter shaft
Be arranged with cutter hub and knife hub, described girff upper end edge cutter shaft prolonging direction be respectively provided on two sides with some corresponding resistance to break-ins
Gold bump.
Further, described antifriction alloy projection include the antifriction alloy bottom being fixedly connected with girff and with resistance to break-in
The capping layer that the top of golden bottom is fixedly connected.
Further, described antifriction alloy height of projection is higher than knife hub 2～3mm.
Further, described antifriction alloy bottom is martensite wear-resistant steel layer, the wear-resisting steel layer of pearlite, high-chromium alloy are cast
Iron layer or carbide layers.
Further, described capping layer high chromium cast iron layer.
Further, the raised quantity of the antifriction alloy of every side is 2.
After technique scheme, this utility model has following beneficial effect: this utility model energy effectively solving
The over worn problem of knife hub, has the advantages that low cost, structure be simple, simple operation.
Brief description
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
In required use accompanying drawing be briefly described it should be apparent that, drawings in the following description are only of the present utility model
Some embodiments, for those of ordinary skill in the art, on the premise of not paying creative work, can also be according to this
A little accompanying drawings obtain other accompanying drawings.

Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, all other embodiment that those of ordinary skill in the art are obtained, all belong to
Scope in this utility model protection.
As Figure 1-3, a kind of wear-resisting type shield machine roller cutter girff device described in this utility model embodiment, including knife
Case 2 and the cutter shaft 1 being located in girff, described girff 2 is provided with end cap 7, described cutter shaft 1 is arranged with cutter hub 4 and knife hub
8, described girff 2 upper end edge cutter shaft 1 prolonging direction be respectively provided on two sides with some antifriction alloy projections 3, described resistance to break-in
Gold bump 3 includes the antifriction alloy bottom 5 being fixedly connected with girff 2 and the lid being fixedly connected with the top of antifriction alloy bottom 5
Surface layer 6.
Antifriction alloy bottom 5 can adopt martensite wear resistant steel, pearlite abrasion-resistant stee, high-chromium alloy cast-iron, tungsten carbide etc., and
And it is not limited to these materials, antifriction alloy bottom 5 is fixedly connected with capping layer 6, capping layer 6 adopts high chromium cast iron material.
In one embodiment, described antifriction alloy projection 3 height are higher than knife hub 2～3mm, and overlay width, length are all in accordance with reality
The design of border situation, during shield digging, due to the presence of antifriction alloy projection 3, rubble only can rub antifriction alloy projection 3,
To reach the purpose of protection knife hub.Knife hub can effectively be protected using the method, and can be with long-term role it is ensured that knife
Tool can be with normal work in lifetime.
In one embodiment, the raised quantity of the antifriction alloy of described every side is 2.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all this
Within the spirit of utility model and principle, any modification, equivalent substitution and improvement made etc., should be included in this utility model
Protection domain within.
