Connect framework, by the detachable door frame lower inside that is connected in of bolt, it plays middle connection function, and hydraulic jack, freight forwarder's walking apparatus and rotating disk are installed in and connect on framework, and by connecting shoring effect in door frame or chassis agent structure.Connect framework and be " well " character form structure, further, the shape that connects framework is equivalent to ladder-shaped.
Rotating disk, for turntable vehicle main body structure, as a kind of optimal way, rotating disk is fastenedly connected and is positioned at the middle part of connection framework with the bottom that is connected framework.Further, when turntable vehicle main body structure, also need install padded 14 additional in the bottom of rotating disk, so that freight forwarder's walking apparatus departs from ground, be convenient to rotate.
Hydraulic jack, for lifting trolley and agent structure thereof, as a kind of optimal way, hydraulic jack number is four and is positioned at the both sides of rotating disk.
Freight forwarder's walking apparatus, is converted to by duty in chassis agent structure after current state (travel position), by freight forwarder's walking apparatus, chassis agent structure is passed through to conventional section from expanding section, moves to the next section that expands.Usually, freight forwarder's walking apparatus can select rail transportation and trackless to transport two kinds, and these two kinds is all existing mature technologies, and therefore, the present embodiment does not repeat.
Implementation procedure of the present utility model is as follows:
Duty:
Steel form carrier is laterally distributed, and it mates with expansion section, and working line walking apparatus contacts with ground rail, forms duty as shown in Figure 1.
The conversion of duty → current state:
(1) steel form carrier is positioned at and expands section in running order, by contraction template support hydraulic pressure oil cylinder, backform, the limit of chassis is touched with bed die and departs from the tunnel concrete face of having built;
(2) adopt bolt that rotation transport establishment is arranged on to door frame lower inside, the parts of installation comprise connection framework, hydraulic jack, rotating disk and freight forwarder's walking apparatus;
(3) by hydraulic jack, steel form carrier is lifted away to ground;
(4) remove height adjustable column, working line walking apparatus and bed die;
(5) in rotating disk bottom, install padded;
(6) fall steel form carrier agent structure, make padded of rotating disk bottom to contact with ground, now, freight forwarder's walking apparatus is lifted away from ground and does not contact with ground;
(7) rotate rotating disk, by connecting framework, drive steel form carrier agent structure to rotate, make it meet the requirement by conventional section;
(8), after having rotated, by hydraulic jack lifting steel form carrier agent structure, make padded disengaging ground under rotating disk;
(9) remove padded;
(10) fall steel form carrier agent structure, freight forwarder's walking apparatus contacts with conveying track, and steel form carrier is converted to travel position from duty, i.e. current state.
Current state:
Steel form carrier agent structure is longitudinal distribution, and it mates with conventional section, and freight forwarder's walking apparatus contacts with conveying track; As shown in Figure 4, wherein, the arc representation that radius is larger expands section in the conversion of the extremely current state of steel form carrier duty, the conventional section of arc representation that radius is less, and the rectangle in it represents steel form carrier agent structure; After converting, by freight forwarder's walking apparatus, move steel form carrier agent structure by conventional section, to the next section that expands; Arrive next expansion after section, by rotating rotating disk, again rotate steel form carrier agent structure, by hoist cylinder lifting steel form carrier agent structure, setting height(from bottom) adjustable column, working line walking apparatus and bed die, form steel form carrier overall structure; Then, fall steel form carrier overall structure working line walking apparatus is contacted with working track, remove and rotate transport establishment, strut shuttering supporting hydraulic jack fixing backform, limit is touched and bed die, steel form carrier returns to duty.
Embodiment 2
The difference of the present embodiment and embodiment 1 is, when the conventional section that need pass through at steel form carrier is larger, now expand section basic suitable with this routine section, therefore, only need do to steel form carrier the adjustment of part, specific practice is: by the difference in height between height adjustable column capable of regulating chassis agent structure and ground, be aided with again the dismounting of segment template, as: bed die and/or limit mould, can realize steel form carrier by the object of conventional section, greatly improved efficiency of construction.
According to above-described embodiment, just can realize well the utility model.What deserves to be explained is; under prerequisite based on above-mentioned design principle; for solving same technical problem; even if some that make on architecture basics disclosed in the utility model are without substantial change or polishing; the essence of the technical scheme adopting is still the same with the utility model, therefore it also should be in protection domain of the present utility model.
