Put.
Background technology
Tunnel be build in underground, under water or in massif, place an iron railway or build highway and be current for motor vehicles
Building.Mountain tunnel, submerged tunnel and city tunnel three major types can be divided into according to its position.For reducing the distance and avoiding
Steep gradient and pass through from the mountain ridge or hills be referred to as mountain tunnel；For river crossing or straits from river or seabed is passed through
It is referred to as submerged tunnel；It is referred to as city tunnel by metropolitan needs what Urban Underground passed through for adapting to railway.
The excavation method in tunnel is divided into cut and cover method and subsurface excavation method, and cut and cover method is used for shallow tunnel or city railway tunnel,
And the multiplex subsurface excavation method of mountain ridge railway tunnel.Divide by excavated section size, position, have partial excavation method and full face tunneling method.?
Stone homogenous rock stratum uses drilling and blasting method the most extensive, use development machine directly to excavate and the most gradually promote.Shield is used in soft geology
Structure method excavation is more.
Drilling and blasting method is jewel hole on tunnel scar, and loads explosive blasting, with full face tunneling or partial excavation etc. by tunnel
The construction method of road excavation molding.Full face tunneling method and partial excavation method are the methods that drilling and blasting method excavation is conventional, but tunnel is executed
Work is the most complicated, time be commonly encountered all difficulties situation, such as major fault, drift sand, expansion stratum, solution cavity, a large amount of retention of excessive fluid etc., still need and take
Corresponding measure.
Shield method is to use shield as the method for tunnel construction of construction equipment, and shield method is applicable to broken ground, construction
Safety, few to ground disturbance, control country rock periphery accurate, seldom backbreak.
Tunnel boring machine method is on whole tunnel cross-section, by the method for the gear construction of driving continuously.
Present stage, the earth dug out, needs were transported by other conveying arrangement, and this needs to put into greatly when tunneling
The manpower and materials of amount, add cost, when excavating, owing to earth falls at headstock, make troubles to moving ahead of vehicle, transport
The earth of this part defeated is, due to the restriction of tunnel space, brings inconvenience to operation.
Utility model content
The purpose of this utility model be in order to solve that present stage earth cleaning after cutting the earth in tunnel is inconvenient, cleaning time time-consuming
Laborious shortcoming, and a kind of earth scraping device for tunnel excavation machine proposed.
To achieve these goals, this utility model adopts the technical scheme that
A kind of earth scraping device for tunnel excavation machine, it is characterised in that: include vehicle frame, in the both sides difference of vehicle frame one end
Being provided with an earth scraping device, earth scraping device includes the connecting plate being connected on the downside of vehicle frame, and connecting plate passes through fixed plate connecting upright pole,
Be rotatably assorted in vertical rod connection rotating plate, connects scraper plate, be additionally provided with hinged seat on connecting plate on flap, and hinged seat connects oil
The oil cylinder seat of cylinder, the piston rod of oil cylinder is hingedly fixed on scraper plate.
On the basis of technique scheme, can there is a technical scheme further below:
It is provided with one group of scraping teeth in the downside of described scraper plate, is also connected with extension plate in the outside of scraper plate.
Flange being arranged below outside described extension plate, the downside of flange is concordant with the downside of described scraping teeth.
It is provided with the sleeve being rotatably assorted with described vertical rod in the side of described flap, the vertical rod on the upside of sleeve is provided with method
Blue dish, the vertical rod between sleeve and ring flange is socketed buffer spring.
Described hinged seat includes two risers be arrangeding in parallel, is provided with rotating cylinder, the oil of described oil cylinder between two risers
Cylinder seat is connected on rotating cylinder, and oil cylinder rotates in perpendicular around rotating cylinder, and oil cylinder is also with the pin joint with described scraper plate as fulcrum
At horizontal rotation in surface.
The utility model has the advantage of: during this device is focused on the earth of tunneling machine both sides by scraper plate and extension plate
Between, same process so that remaining clean state before tunneling machine, earth cleaning is convenient, speed is fast, time saving and energy saving.
