Description
Technical field
The utility model relates to tunnel driving equipment technical fields, exempt from the double shields of real-time observation type that open a window more particularly, to one kind
Shield TBM.
Background technique
TBM is the abbreviation of complete-section tunnel boring machine, mainly utilizes rotating tool extrusion shearing broken rock, and rock ballast passes through rotation
Dipper teeth on rotor disk is picked up, and is fallen on host belt feeder to traction slag vehicle or the conveying of tunnel continuous conveyor system, is led to later
It crosses traction slag vehicle or tunnel continuous conveyor system transports to rock ballast outside hole.TBM is broadly divided into open type TBM, list shield TBM and double
Shield TBM etc..Wherein, double-shielded TBM is adaptable to geological conditions, it can be achieved that the synchronous progress of excavation and support, drivage efficiency
Height, using extremely wide in Deep-buried Long And Big tunnel construction.Double-shielded TBM refers to be provided with and machine diameter phase one in host periphery
The round shield structure of cause, shield by the anterior shield, branch pole and tail shield that are sequentially connected at.In order to observe rock mass, on a shield left side
The observation window being bolted respectively is arranged in right two sides, and window size is mostly 30*50cm, and viewing area is smaller.Meanwhile by
Inclement condition when construction, observation window are easily blinded by dust, and operator usually requires to remove observation window bolt after a shutdown
It is observed, not only time-consuming and laborious, moreover, fragmented rock body is often fallen into shield shell after opening observation window, damage shield shell is set
It is standby or injure personnel by a crashing object.Therefore, geological conditions is poorer, and observation window does not have effect.
Summary of the invention
The utility model provides one kind and exempts from the real-time observation type double-shielded TBM that opens a window, it is therefore intended that solves existing observation window and holds
The problem of influence observation is easily blinded by dust.
To achieve the above object, the utility model can take following technical proposals:
It is described in the utility model to exempt from the real-time observation type double-shielded TBM that opens a window, including shield, the left and right sides of the shield
Watch window is offered, sealed set has arc armoured glass, setting on the outside of the arc armoured glass in the watch window
There is the cleaning brush moved back and forth along axial slide, the brush head of the cleaning brush is perpendicular to the axial slide.
The radian of the arc armoured glass and shield matches.
The axial slide is arranged on shield and/or arc armoured glass, and is located in the middle part of the watch window.
The brush head of the cleaning brush is the arcuate structure isometric with arc armoured glass cross section.
The brush head of the cleaning brush is flexibly connected with brush handle, and the brush handle other end is slidably connected in the axial slide
And it is connected with electric driver.
The shield each side opens up that there are two the watch window circumferentially arranged, the arc armoured glass four
It is coated with elastic sealing layer week, and is bolted in the watch window.
The shield includes anterior shield, branch pole and/or tail shield.
It is provided by the utility model to exempt from the real-time observation type double-shielded TBM that opens a window, by the high-strength arc for being mounted on shield bilateral
Shape glass forms biggish watch window, using cleaning brush matched with observation window clean dust on the outside of high-strength arc glass,
Landwaste facilitates operator to observe the country rock situation in TBM construction tunnel in real time.The utility model has structure letter
The advantages of list, design are reasonable, convenient for observation, can greatly reduce the downtime of TBM, and easy to maintain.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model (observation window segment).
Fig. 2 is the A-A the schematic diagram of the section structure in Fig. 1.
Specific embodiment
As shown in Figure 1, 2, described in the utility model to exempt from the real-time observation type double-shielded TBM that opens a window, including it is provided with support
The watch window 2 of 1 left and right sides of shield, in order to expand the visual field, two watch windows circumferentially arranged 2 are set side by side in every side, and
High-strength arc armoured glass 3 is fixedly installed with by bolt 6 in each watch window 2, in order to reach sealing purpose, each
High-strength 3 surrounding of arc armoured glass has been respectively coated by elastic seal ring made of the materials such as silica gel.It is high-strength in order to fall in time
Dust, the rock ballast on 3 surface of arc armoured glass remove, and are mounted in the outside of each high-strength arc armoured glass 3 along axial direction
The cleaning brush that sliding slot 4 moves back and forth.Specifically, cleaning brush includes 5.2 two parts of brush head 5.1 and brush handle, wherein 5.1 edge of brush head
The direction setting vertical with axial slide 4, using the arc structure isometric with high-strength 3 cross section of arc armoured glass, so as to more
It fits with high-strength arc armoured glass 3 well, achievees the purpose that improve dust removing effects.Since brush head 5.1 is vulnerable part, in order to
It is conveniently replaceable, brush head 5.1 is movably connected with brush handle 5.2, and the other end of brush handle 5.2 is then slidably mounted on axial slide 4
Interior and be connected with electric driver 7, the commercial equipments such as electric cylinders can be selected in above-mentioned electric driver 7.In order to improve brush head 5.1 past
Stability in multiple motion process, axial slide 4 are generally located on 2 middle part of watch window, and length is then by the movement of brush head 5.1
Range and the length of brush handle 5.2 determine, or are provided separately in 1 shield body of branch pole, on the inside of the outer edge of shield 1 or with shield
The outer edge of shield 1 is overlapped；Or it is provided separately on arc armoured glass 3；Or from arc armoured glass 3 always to 1 shield of branch pole
Extend on body.In addition, should also determine size, character etc. according to TBM device model, hole diameter size, geological conditions etc. are comprehensive, there is choosing
High-strength arc armoured glass 3 is installed to selecting property on anterior shield and/or tail shield.
The utility model can start cleaning brush at any time and carry out clearly to high-strength arc armoured glass 3 in TBM start process
It is clean, facilitate operator to observe the country rock situation in TBM construction tunnel in real time.Its simple structure and reasonable design is convenient for
Observation, can greatly reduce the downtime of TBM.
