Abstract
The invention relates to a bridge-deck portal bridge girder erection machine for erecting a cantilever steel beam in the field of bridge construction equipment and can be used for solving the problem of erecting the steel beam in a narrow unnavigable area. The invention provides the following technical scheme that the bridge-deck portal bridge girder erection machine is characterized by comprising a frame, wherein the frame is provided with a movable lifting appliance; both sides of one end of the frame are respectively provided with supporting feet; the bottom parts of the supporting feet are provided with guide rails; the guide rails are in sliding fit with the supporting feet; and supporting rods of the supporting feet, which are positioned at one side of the middle part of the frame, are on the same line with a girder at the same side. Due to the adoption of the scheme, the invention aims to overcome the defects in the prior art and provide the novel bridge-deck portal bridge girder erection machine which is used for design and construction of a long-span steel truss stiffening girder suspension bridge and can be used on a bridge with a long span.
Description
Technical field
The present invention relates in a kind of equipment for bridge construction field the setting up of cantilever girder steel, can solve the narrow regional steel girder erection of not opening the navigation or air flight bridge-deck portal bridge girder erection machine.
background technology
At present, to the setting up of narrow location Steel Truss Beam, generally adopt erection crane and mast loop wheel machine, from bridge, get beam, for the area of not opening the navigation or air flight and cannot transport under bridge, utilize current device to set up and have certain difficulty.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, providing a kind of is large design and construction across steel purlin stiff girder suspension bridge, and the novel bridge-deck portal bridge girder erection machine that can use in span very bridge.
For achieving the above object, the invention provides following technical scheme: a kind of bridge-deck portal bridge girder erection machine, it is characterized in that: include frame, movably suspender is set in described frame, the both sides of described frame one end are respectively arranged with feet, the bottom of feet arranges guide rail, this guide rail coordinates with feet slip, the both sides of described central rack are vertical is with it provided with two girders, between two girders, by link, be fixedly connected with, every girder is connected with the two ends of frame by connecting rod respectively, the support bar that is positioned at central rack one side of described feet and the girder of homonymy are located along the same line.
By adopting such scheme, we can sling and move object, very convenient, are provided with in addition girder, can make the Bridge Erector supporting capacity of this structure greatly be strengthened, and the object that track is set is to Bridge Erector, to move easily.
The present invention further arranges: described feet includes two support bars and fixed mount, between two support bars, by fixed mount, fix, the upper end of support bar is fixedly supported in frame, the lower end of support bar is provided with roller, the downside of described fixed mount is also provided with roller, on the roller on support bar and the roller on fixed mount, interts and is provided with a guide rail.
By adopting such scheme, Bridge Erector is moved stable, can not depart from, the supporting foot structure of this mode is simple, reasonable, and support force is large.
Last setting of the present invention is: between described guide rail and fixed mount or support bar, be provided with horizontal oil cylinder, the bottom of described feet and a side that is positioned at guide rail arrange longitudinal oil cylinder.
By adopting such scheme, we can first pass through longitudinal oil cylinder the slight jack-up of Bridge Erector in mobile Bridge Erector, and the power between Bridge Erector and guide rail is just very little like this, and then by horizontal oil cylinder movement guide rail, move on to after certain position, put down longitudinal oil cylinder, fixed guide, and then by horizontal oil cylinder, at this time guide rail is fixed, and Bridge Erector moves, thereby realize Bridge Erector, moves, scheme is simple, mobile reliable.
Below in conjunction with accompanying drawing, the invention will be further described.
