Abstract
The utility model discloses a suspension structure for a propelling trolley of a bridge fabrication machine. The suspension structure comprises a change gear, a change gear seat, a guide wheel, a transverse beam, a longitudinal connecting rod and a finished deformed bar, wherein the change gear is capable of bulging outwards along the circumferential direction at the rolling outside part at the top of a rail to form a convex ring; the change gear seat is connected to the outside of the change gear; the guide wheel is connected at the inside of the change gear seat and is capable of rolling along the bottom of the rail; the transverse beam is connected at the inside of the change gear seat; the longitudinal connecting rod is connected with the transverse beam; and the finished deformed bar is connected at the bottom of the change gear seat and a mobile trolley; and an upper clamping rail and a lower clamping rail of the change gear and the guide wheels are connected into a body, the transverse beam and the longitudinal connecting rod are connected with the change gear seat into a body, and the convex ring is matched with a pair of guide wheels, the transverse beam and the longitudinal connecting rod can ensure that the change gear and the rail cannot generate relative displacement, therefore, the structure is stable, and the maintenance cost of the equipment is lower.
Description
Technical field
The utility model relates to the suspended structure that bridge fabrication machine advances dolly
Background technology
In existing bridge Construction Technology, suspended structure is welded as a whole with advancing dolly, suspended structure can be moved on pair of tracks by the change gear of self, advance dolly to be welded on the bottom of suspended structure, when the change gear of suspended structure moves, can drive the propelling moving of car, like this after equipment uses a period of time, relative displacement might take place between track and the suspended structure, and then the center of gravity of travelling car is changed, can produce the gap between change gear and the track, cause the maintenance cost of equipment higher like this
Summary of the invention
The purpose of this utility model provides the suspended structure that the low bridge fabrication machine of Stability Analysis of Structures, maintenance cost advances dolly.
For achieving the above object, the technical solution adopted in the utility model is: a kind of bridge fabrication machine advances the suspended structure of dolly, described suspended structure is arranged on the track of the pair of parallel that plays a supportive role, described suspended structure comprises a pair of gear changing group that can roll along described pair of parallel track top respectively, be connected to a pair of change gear seat in the described a pair of gear changing group outside, be suspended on the propelling dolly of described a pair of change gear seat below, described each extension opinion group comprises at least two change gears, the outside portion of described change gear outwards convexes to form bulge loop along circumferential direction, be oppositely arranged a pair of directive wheel that can roll along described pair of parallel track bottom in the inboard of described a pair of change gear seat, described change gear is identical with described directive wheel rotating direction, the pair of beams that connects described a pair of change gear seat middle inside is set below described a pair of directive wheel, the a pair of longitudinal rod that connects described pair of beams is set, described pair of beams, described a pair of longitudinal rod is connected as a single entity described a pair of change gear seat.
Preferably, a pair of vertical parallel finish rolling deformed bar is set, described a pair of finish rolling deformed bar one end is connected described change gear seat bottom, and the other end is connected the both side ends of described propelling dolly.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage: will advance dolly and suspended structure branch to be arranged, change gear outside portion radial dimension in the suspended structure is become big, make it to form the bulge loop of circumferential direction, in the change gear outside change gear seat is set respectively, below change gear, be oppositely arranged a pair of directive wheel that is connected change gear seat inboard, the a pair of crossbeam that is connected change gear seat inboard is set below change gear in addition, the longitudinal rod that connects pair of beams is set, to advance dolly to be suspended on change gear seat bottom by finish rolling deformed bar, like this when the change gear motion of suspended structure, bulge loop, crossbeam, longitudinal rod has limited relatively moving between track and the suspended structure, can not produce relative displacement, Stability Analysis of Structures between change gear and the track, the maintenance cost of equipment is lower.
Description of drawings
Accompanying drawing 1 is looked schematic diagram for master of the present utility model;
Accompanying drawing 2 is a schematic side view of the present utility model.
The specific embodiment
Further set forth structure of the present utility model below in conjunction with accompanying drawing.
Referring to shown in Figure 1, hitch has a pair of gear changing group that can roll as 2 on the parallel orbit 1 at girder top, a pair of change gear seat is set as 3 in a pair of gear changing group respectively as 2 the outside, be oppositely arranged a pair of a pair of directive wheel that can roll as 4 in a pair of change gear seat inboard along parallel orbit 1 bottom, directive wheel is as 4 belows that are positioned at parallel orbit 1, gear changing group up and down clamps parallel orbit 1 with directive wheel as 4 as 2, can make the operation of suspended structure on parallel orbit 1 more stable, gear changing group is not easy to take place flop phenomenon as 2, be provided with below at a pair of directive wheel and connect the pair of beams 5 of a pair of change gear seat as 3 inboards as 4, the a pair of longitudinal rod 6 that connects pair of beams 5 is set in addition, pair of beams 5, a pair of longitudinal rod 6 can connect a pair of change gear seat as a whole as 3, make to be difficult for taking place relative displacement between pair of tracks 1 and the suspended structure.
Referring to shown in Figure 2, each gear changing group has two change gears as 2, the stability of suspended structure operation has been guaranteed in the setting of two change gears, the change gear outside portion outwards convexes to form bulge loop along circumferential direction, bulge loop cooperates a pair of directive wheel as 4, pair of beams 5, a pair of longitudinal rod 6 makes relative displacement does not take place between pair of tracks 1 and the suspended structure, the finish rolling deformed bar 7 of a pair of adjustable length is set as 3 bottoms at a pair of change gear seat, travelling car 8 is suspended on a pair of finish rolling deformed bar 7 by self both ends, can guarantee the stressed even of 4 change gears by the length of regulating a pair of finish rolling deformed bar 7, make to advance the operation of dolly suspended structure more stable
