Abstract
The invention discloses a hob capable of being pushed out, which includes an oil cylinder arranged on a TBM (tunnel boring machine) cutter, a sliding part movably connected with the cutter and driven by the oil cylinder to move, and a hob connected on the sliding part. Due to the adoption of the technical scheme, the hob capable of being pushed out can adjust the hob position through adjusting the oil cylinder feed rate when being used for tunnel chambering and trimming, and further a cutter I is pushed out to meet the requirements of chambering and trimming. The hob capable of being pushed out also can serve as a standby hob; after other hobs are worn, the standby hob is pushed out of the cutter and the number of hob change times is reduced.
Description
Technical field
The present invention relates to a kind of cutter, but relate in particular to a kind of push type hobboing cutter.
Background technology
Shielding tunnel excavator, be called for short shield machine, a kind of special engineering machinery of tunnel piercing, with shield machine carry out tunnel construction have automaticity high, save that manpower, speed of application are fast, controllably face sedimentation when cavitation, weatherproof, excavation, reduce the impact of above ground structure and do not affect the characteristics such as water surface traffic while excavating under water, in the situation that the tunnel line is long, buried depth is larger, with more economical rationality of shield machine construction.
The hobboing cutter of installing on cutter head of shield machine is generally fixed, when tunnel reaming, deburring, need to manually be adjusted or change hobboing cutter, once the tool changing complex steps need to be manually changed in fixed hobboing cutter wearing and tearing in addition.
Summary of the invention
In order to address the above problem, but the object of the present invention is to provide a kind of push type hobboing cutter.
In order to reach above purpose, the technical solution used in the present invention is: but the push type hobboing cutter, is connected to the hobboing cutter on sliding part at the sliding part that it comprises the oil cylinder that is arranged on cutter head of shield machine, is connected movably mutually with cutterhead and moved by hydraulic oil cylinder driving.
Further, be fixed with fixed housing on cutterhead, sliding part is arranged in fixed housing movably.
Further, be provided with the lubrication oil injection hole on fixed housing, between sliding part and fixed housing, be provided with seal.
Further, an end of oil cylinder is fixed on cutterhead, and the other end and sliding part fix.
Further, be fixed with hob head on sliding part, hobboing cutter is arranged on hob head.
Owing to having adopted technique scheme, but the present invention's push type hobboing cutter, when carrying out tunnel reaming and deburring, is adjusted the hobboing cutter position by adjusting the oil cylinder amount of feeding, will further release cutterhead one and meet the demand of reaming and deburring; But the present invention's push type hobboing cutter can also after other limit hob abrasions, be released cutterhead by standby hobboing cutter as standby hobboing cutter, has reduced number of changing knife.
The accompanying drawing explanation
But accompanying drawing 1 is the structural representation of the present invention's push type hobboing cutter.
Number in the figure is:
1, oil cylinder; 11, cylinder pedestal; 2, fixed housing; 21, seal; 22, lubrication oil inlet; 3, sliding part; 4, hob head; 5, hobboing cutter.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Can find out from the structural representation of accompanying drawing 1, but the invention provides the push type hobboing cutter, it comprises the oil cylinder 1 that is arranged on cutter head of shield machine, with cutterhead, is connected movably mutually and by oil cylinder 1 drive movement sliding part 3, be connected to the hobboing cutter 5 on sliding part 3.Hobboing cutter 5 in the present embodiment is double-edged hobbing cutter.
Be fixed with fixed housing 2 on cutterhead, sliding part 3 is arranged in fixed housing 2 movably.
Be provided with lubrication oil injection hole 22 on fixed housing 2, be used for relatively moving between sliding part 3 and fixed housing 2 is lubricated, between mobile sliding part 3 and fixed housing 2, be provided with seal 21, the seal 21 is arranged on the both sides of lubrication oil inlet 21.Be fixed with end cap 23 at the two ends of fixed housing 2, be bolted between end cap 23 and fixed housing 2 in the present embodiment.
Be fixed with hob head 4 on sliding part 3, hobboing cutter 5 is arranged on hob head 4.
But the push type hobboing cutter in the present embodiment has at least two duties during as standby hobboing cutter, be stand-by state and use state, when under stand-by state, hobboing cutter 5 is positioned at the inside of cutter head of shield machine, when under the use state, hobboing cutter 5 is released cutter head of shield machine by oil cylinder 1.
But the push type hobboing cutter in the present embodiment, when carrying out tunnel reaming, deburring, can be adjusted the position of hobboing cutter 5, to meet the dimensional requirement of reaming and deburring by the amount of feeding of adjusting oil cylinder 1.
Above-described embodiment is only explanation technical conceive of the present invention and characteristics, and its purpose is to allow the person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences that Spirit Essence is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
