Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, simply introduce to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
The front view of the reverse arm system of two Shield TBMs that Fig. 1 provides for the utility model embodiment;
The sectional drawing of the reverse arm system of two Shield TBMs that Fig. 2 provides for the utility model embodiment.
Detailed description of the invention
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The front view of the reverse arm system of two Shield TBMs that Fig. 1 provides for the utility model embodiment; The sectional drawing of the reverse arm system of two Shield TBMs that Fig. 2 provides for the utility model embodiment.With reference to Fig. 1 and Fig. 2, the reverse arm system of two Shield TBMs that the present embodiment provides, specifically can comprise:
Two groups of reverse arms, described two groups of reverse arms are separately positioned on the both sides in described pair of Shield TBM shield, and before described pair of Shield TBM between shield 101 and rear shield 102.
Before described pair of Shield TBM, two groups of reverse arms are set between shield 101 and rear shield 102, the dual-use function of oil cylinder V-type in prior art arranged separately, the twisting states of shield 101 before controlling by means of only two groups of reverse arms, solve in prior art, before and after correcting, during the twisting states of shield 102, development machine needs to stop driving and the low problem of two Shield TBM service efficiencies of causing, improves the service efficiency of pair Shield TBM.
Wherein, often organize described reverse arm and comprise upper arm 103 and underarm 104; Described upper arm 103 is arranged on described front shield 101, and described underarm 104 arranges in the rear on shield 102; Connect by reversing oil cylinder 105 between described upper arm 103 and described underarm 104; The duty of the described torsion oil cylinder 105 described in two groups between upper arm 103 and underarm 104 is contrary.
Concrete, the duty of the described torsion oil cylinder 105 described in two groups between upper arm 103 and underarm 104 refers on the contrary, and reverse oil cylinder 105 described in one of them when stretching out, another reverses oil cylinder 105 and retracts.By arranging two groups of reverse arms, making two to reverse oil cylinder 105 simultaneously for front shield 101 provides moment of torsion, compared to prior art, the moment of torsion that front shield 101 is enough can be supplied to, make front shield 101 be in metastable state.
Under normal circumstances, two are reversed oil cylinder 105 is locked, and when cutterhead rotates, reverse arm provides reaction torque to cutterhead, and front shield 101 can not rotate substantially.But when development machine works, reverse oil cylinder 105 in running order for a long time, because the reasons such as hydraulic system leakage may cause front shield 101 to rotate, now, two can be operated and reverse oil cylinder 105, front shield 101 is adjusted to normal position.
Looking forward below from two Shield TBM, cutterhead turns clockwise under normal circumstances, the moment of resistance that such cutterhead is subject to rock is anticlockwise, front shield 101 is made to have the trend be rotated counterclockwise for a long time, become a reality if this trend makes front shield 101 be rotated counterclockwise, just should operate torsion oil cylinder 105 and front shield 101 is resetted.
Wherein, two reverse oil cylinder 105 always one stretch out retractions, like this relative to tunnel center line two torsion oil cylinders 105 just provide the moment of torsion of equidirectional.Look forward after two Shield TBM, the torsion oil cylinder 105 on the left side stretches out, and the torsion oil cylinder 105 on the right is retracted, and such two torsion oil cylinders 105 just can drive front shield 101 to adjust clockwise; On the contrary, look forward after two Shield TBM, if the torsion oil cylinder 105 on the left side is retracted, the torsion oil cylinder 105 on the right stretches out, then reverse oil cylinder 105 and drive front shield 101 to adjust counterclockwise.
The reverse arm system of two Shield TBMs that the utility model provides, comprise two groups of reverse arms, described two groups of reverse arms are separately positioned on the both sides in the shield of described pair of Shield TBM, and between the front shield and rear shield of described pair of Shield TBM, wherein, often organize described reverse arm and comprise upper arm and underarm; Described upper arm is arranged on described front shield, and described underarm arranges in the rear on shield; Connect by reversing oil cylinder between described upper arm and described underarm, and two duties reversing oil cylinder are contrary; These two groups of reverse arms can provide reaction torque to cutterhead, front shield can not be rotated, and in the development machine course of work, operate two and reverse oil cylinder, make one of them stretch out, another is retracted, and two are reversed the moment of torsion that oil cylinder provides equidirectional, thus the enough opposing moments of torsion of front shield can be supplied to, greatly improve the service efficiency of equipment.
Last it is noted that above each embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to foregoing embodiments, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein some or all of technical characteristic; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of each embodiment technical scheme of the utility model.
