Shield gantry vehicle device turning radius manufactures and designs the stage at equipment and determines, general turning radius is 200m left and right, but generally in work progress, emergency case causes practice of construction condition and initial setting to change, need the follow-up chassis equipment of shield structure carry out small curvature radius (≤100m) turn to by, under condition like this, shield gantry Car Track radius is less than shield gantry car design turning radius, do not meet Suporting structure requirement, cause shield gantry car cannot pass through trolley track, cause engineering to construct, thereby cause heavy losses in programming and economic aspect.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of novel shield gantry vehicle device small curvature radius to turn to slide device, to overcome described defect of the prior art.
[utility model content]
For addressing the above problem, the purpose of this utility model is to provide a kind of installation quick, convenient, cost shield gantry vehicle device small curvature radius low and that can meet construction requirement turns to slide device, it need not remove former trolley track, make the follow-up chassis equipment of shield structure in origination process, carry out small curvature radius turn to by.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of shield gantry vehicle device small curvature radius turns to slide device, and it comprises shield gantry car, shield structure trolley running track, chassis slide surface steel plate, supports shaped steel, jack, jack counter-force fixture and jacking block; Wherein, described shield structure pallet bottom is provided with trolley running wheels; Described chassis slide surface steel plate is laid on shield structure trolley running track; Described trolley running wheels are positioned on chassis slide surface steel plate; Described support shaped steel is arranged on the both sides of shield structure trolley running track; Described jack counter-force fixture is immobilizated in and supports on shaped steel; Described jack one end is connected on jack counter-force fixture, and the other end is connected on jacking block; Described jacking block is connected to the outside of trolley running wheels.
Shield gantry vehicle device small curvature radius of the present utility model turns to slide device to be further set to: in the bottom of described chassis slide surface steel plate, be provided with some reinforcement tracks, described reinforcement track and shield structure trolley running track are parallel to each other and are contour.
Shield gantry vehicle device small curvature radius of the present utility model turns to slide device to be also set to: between the two ends of described chassis slide surface steel plate and shield structure trolley running track, adopt and be connected smoothly.
Compared with prior art, the utlity model has following beneficial effect: it is normal by construction in small curvature radius situation that shield gantry vehicle device small curvature radius of the present utility model turns to slide device can meet shield gantry car, guaranteed the stable and working security of attitude in chassis moving process; Its practical effect is good, shield gantry car is guaranteed by small curvature radius safety, and this way is simple to operate, easy accessibility, need not remove former trolley running track, greatly save operating expenses and time, avoided not meeting due to engineering specifications the requirement of Suporting structure minimum turning radius, caused shield gantry car cannot pass through trolley track, cause engineering to construct, thereby cause heavy losses in programming and economic aspect.

[specific embodiment]
Refer to Figure of description 1 to shown in accompanying drawing 3, the utility model is that a kind of shield gantry vehicle device small curvature radius turns to slide device, and it is comprised of several parts such as shield gantry car 1, shield structure trolley running track 2, chassis slide surface steel plate 3, support shaped steel 4, jack 5, jack counter-force fixture 6 and jacking blocks 7.
Wherein, described shield gantry car 1 bottom is provided with trolley running wheels 8.
Described chassis slide surface steel plate 3 is laid on shield structure trolley running track 2, between the two ends of this chassis slide surface steel plate 3 and shield structure trolley running track 2, adopt and be connected smoothly, thereby guarantee that trolley running wheels 8 move to chassis slide surface steel plate 3 tops smoothly.Described trolley running wheels 8 are positioned on this chassis slide surface steel plate 3
In the bottom of described chassis slide surface steel plate 3, be provided with some reinforcement tracks 9, described reinforcement track 9 and shield structure trolley running track 2 are parallel to each other and are contour.This rail level height of strengthening after track 9 assurances have spread is identical, makes shield gantry car 1 turn to slide surface stressed evenly, can meet the requirement of strength that shield gantry car 1 turns to slipping.
Described support shaped steel 4, jack 5, jack counter-force fixture 6 and jacking block 7 form shield gantry car 1 and turn to slippage dynamical system, make shield gantry car 1 carry out level and turn to slippage, to the adjustment that links of the horizontal level of shield gantry car 1, make shield gantry car 1 final by small curvature radius region.
