Background technology
Shield machine is a kind of special engineering machinery of tunnel piercing, is equipment indispensable in tunnel construction.Shield
Structure machine propulsion system is one of most important part of shield machine, with the raising of shield tunnel quality requirement, propelling cylinder
Drift angle regulation turns into the problem of very important.
The most popular shield machine of municipal tunnel is mainly earth pressure balance shield machine in global range at present, and municipal
The design route of shield tunnel is usually curve, and when in use, shield machine articulated position has certain angle to shield machine, this
When, can also there is certain angle between the direction being allocated as firmly and active force section of jurisdiction suffered by propelling cylinder, in such case
Under, when by thrust is larger be when, in the case of vertical, the section of jurisdiction posture in whole piece tunnel is it is possible that some are inclined
Move, precast concrete section of jurisdiction is it is possible that breakage.Earth pressure balance shield machine at present, there are two kinds to change for such case
Enter mode：The first is that articulated position moves forward, and is that propelling cylinder is remained on same straight line with section of jurisdiction, such case
Under, shield machine back body is longer, and during compared with tight turn radius, rear portion shield shell is likely to occur the phenomenon being stuck；Another kind be by
Propelling cylinder support boots are designed to ball pivot form, are occurred damaged situation by tangential force to prevent section of jurisdiction, and whole piece tunnel duct piece appearance
State still by and tangential component influenceed, skew still occurs in tunnel posture.
It is therefore desirable to design a kind of shield machine thrust oil cylinder drift angle adjusting means, to overcome above mentioned problem.
Utility model content
The purpose of this utility model is the defect for overcoming prior art, there is provided a kind of to adjust propelling cylinder at any time
Angle is offset, and makes the maximized shield machine thrust oil cylinder drift angle adjusting means of angle of regulation range.
What the utility model was realized in：
The utility model provides a kind of shield machine thrust oil cylinder drift angle adjusting means, including two be arranged in shield body push away
Enter oil cylinder, two propelling cylinder one end are fixed in shield body by ball pivot, and the other end acts on duct pieces of shield tunnel by supportting boots
On, Fixing shrink ring is equipped with two propelling cylinders, two Fixing shrink rings are hinged by connecting plate, are provided with around Fixing shrink ring more
Individual small oil tank, multiple fixed blocks is welded with small oil tank relevant position in shield body, the push rod of small oil tank is fixed on fixed block.
Further, multiple small oil tanks are controlled to adjust by hydraulic control valve group.
Further, Fixing shrink ring is hinged by jointed shaft and connecting plate.
Further, Fixing shrink ring is made up of two pieces of ring plates, and two pieces of ring plates are bolted connection.
Further, small oil tank and fixed block are equipped with 8.
The utility model has the advantages that：
Shield machine thrust oil cylinder drift angle of the present utility model adjusting means is simple in construction, easy for installation, can at any time adjust and push away
Enter the angle skew of oil cylinder, and maximize angle of regulation range, to ensure the quality of section of jurisdiction in shield tunnel construction, make simultaneously
Thrust when shield machine tunnels maximizes.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of shield machine thrust oil cylinder drift angle provided by the utility model adjusting means；
Fig. 2 is the fundamental diagram of shield machine thrust oil cylinder drift angle provided by the utility model adjusting means.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Such as Fig. 1 and Fig. 2, shield machine thrust oil cylinder drift angle of the present utility model adjusting means, including it is arranged in shield body
Two propelling cylinders 1, two one end of propelling cylinder 1 are fixed in shield body by ball pivot, and the other end acts on shield by supportting boots
On tunnel duct piece.Because section of jurisdiction is integrally fixed in tunnel, so as to promote shield body to push ahead to the reaction force of propelling cylinder 1.
When shield machine need to turn, it is not coaxial to allow for the center line of the axis and section of jurisdiction wall of propelling cylinder 1, is easily destroyed section of jurisdiction, this thing
Then need to adjust by drift angle adjusting means.
Fixing shrink ring 2 is equipped with two propelling cylinders 1, two Fixing shrink rings 2 are be hinged by connecting plate 3, wherein, it is fixed
Ring set 2 is be hinged by jointed shaft 31 and connecting plate 3 according to required regulation spacing.In order to facilitate installation, Fixing shrink ring 2 is by two pieces of rings
Piece 21 forms, and two pieces of ring plates 21 are bolted connection.Multiple small oil tanks 4 are provided with around Fixing shrink ring 2, multiple small oil tanks 4 are logical
Undue four different directions are fixed on the diverse location of Fixing shrink ring 2 to realize the regulation of different directions.In shield body with small oil tank 4
Relevant position is welded with multiple fixed blocks 5, and the push rod of small oil tank 4 is fixed on fixed block 5, and multiple small oil tanks 4 are by hydraulic control
Valve group 6 controls to adjust, and a set of hydraulic control valve group 6 controls the angular adjustment of a propelling cylinder 1.
In order to further expand the regulation angular range of propelling cylinder 1, small oil tank 4 and fixed block 5 are equipped with 8.
During work, two kinds of mode of operations of locking mode and floating mode may be selected, when being worked using locking mode, hydraulic pressure
The check valve 61 of control valve group 6 locks, and now propelling cylinder 1 is in fixed mode；When using floating mode, check valve 61 can
With oil return, small oil tank 4 is controlled to adjust by hydraulic control valve group 6 to be influenceed to be floated by external force, and the bottom of propelling cylinder 1 uses
Spherical hinge structure can be movable, and propelling cylinder 1 can be so adjusted to certain drift angle, ensures the axis of propelling cylinder 1 and section of jurisdiction wall
Center line it is coaxial.
In summary, shield machine thrust oil cylinder drift angle of the present utility model adjusting means is simple in construction, easy for installation, can be with
When adjust the angle skew of propelling cylinder, and maximize angle of regulation range, to ensure the matter of section of jurisdiction in shield tunnel construction
Amount, while thrust when tunneling shield machine maximizes.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in
