Description
Technical field
The utility model is related to a kind of scraper for shield machine seat positioning tools in shield machine technical field.
Background technology
Capital equipment of the shield machine as shield construction, plays highly important role in the construction process.Cutterhead
As the main working parts of shield machine, has in tunneling process and excavate stratum, stablize face（Tunnel excavation face）, stirring
The functions such as dregs.What scraper was played when cutterhead tunnels act as：One, the scraping soil body, since it is mounted on cutterhead front dregs
Beside flowing groove, i.e., the country rock loosened after hobboing cutter breakage can be scraped in cutterhead rotation process, the dregs under scraping is made to pass through
Dregs flowing groove plays the role of scraping slag into storehouse of burying；Two, scraper plays the role of protection hobboing cutter, and hobboing cutter is made to reduce eccentric wear（Such as
Eccentric wear occurs for hobboing cutter, and cutterhead easily forms mud cake）.Scraper is properly positioned abrasion of the installation relation to scraper on cutter head panel
Speed and working performance, and the key that scraper is properly positioned is scraper base being properly positioned in cutterhead working surface.
The group of scraper base is to there are following technical problems in position fixing process at this stage：1. using scraper base is manually adjusted
When coordinating spirit level positioning, since cutter head structure is limited, staff, which needs to squat, to bend to carry out scraper on cutterhead spoke edge
The group to point weldering of seat, limited working space influence positioning accuracy；2. due to scraper base top planes very little, using load leveling ruler side
When method, ruler is not easy to place, extends the time of adjustment positioning；The 5.5kg 3. standard 120mm broad knife seats are conducted oneself with dignity, long-time hand
Dynamic adjustment fatiguability, is unfavorable for accuracy guarantee of the group to flatness and height.It can be seen that coordinating level using load leveling ruler method
Manual group of instrument is to positioning scraper base, and precision is not easy guarantee, personnel are easy to fatigue and it is more to expend working hour.Therefore, it develops
A kind of scraper for shield machine seat positioning tool is always new issue anxious to be resolved.
Utility model content
The purpose of this utility model is to provide a kind of scraper for shield machine seat positioning tool, which passes through simple
Tool structure design realize scraper base quick positioning, can be good at ensure precision, reduce worker labor intensity, save
Working hour improves positioning engineering method-load leveling ruler method of existing scraper base, realize scraper base it is quick, be accurately positioned, tower structure behaviour
Make simply, easy to adjust, the setting of centralized positioning groove is easy to the measurement of radius and height and the observation of scraper base level, improves
Working efficiency.
What the purpose of this utility model was realized in：A kind of scraper for shield machine seat positioning tool, including scraper base, knife
Disk spoke, bracket, adjusting screw, positioning screw, welded nut, is threadedly coupled plate, unthreaded hole connecting plate, guide plate at holder, in knife
The both sides of disk spoke are symmetrical arranged scraper base, and scraper base is arranged on the outside of cutterhead spoke, and holder is the rectangular frame of steel plate welding
Formula structure, holder are connect with plate is threadedly coupled, and are fixed on cutterhead spoke with adjusting screw and welded nut by plate is threadedly coupled,
Bracket is welded-steel plate construction, and bracket is fixed on scraper base with positioning screw, guide plate is provided on scraper base, in bracket
Upper setting unthreaded hole connecting plate.
The utility model is characterized by its structure, and operation principle is：It is when welding scraper base, two pieces scraper base is each
It is put into the bracket of both sides, at this point, under the action of guide plate, holder is placed on knife by scraper base automatic centering together with bracket
In disk spoke, the orbital radius of scraper base is adjusted first with the center groove on holder, then by adjusting screw and welded nut
Screw thread pair cooperation adjust integral level degree and height, realize whole positioning finally by positioning screw.
A kind of scraper for shield machine seat positioning tool compared with prior art, has simple in structure, is easily assembled, adjustment side
Just, a tooling can position two scraper bases arranged on same orbital radius simultaneously, meet radius tolerances and height tolerance two
The requirement in a direction, is convenient for measuring, and is suitable for different types of scraper base and installs, multiple toolings use simultaneously, by spirit level
The advantages that measuring and adjust simultaneously, realizing fast accurate positioning, will be widely used in shield machine technical field.
