Abstract
The utility model discloses an intermediate supporting mechanism for a bridge girder erection machine of a road. The intermediate supporting mechanism for the bridge girder erection machine of the road comprises a reverse supporting wheel box, an intermediate supporting rotating seat and a transverse moving travelling wheel box set; the reverse supporting wheel box is hinged with the internal supporting rotating seat through a hinge pin; the intermediate supporting rotating seat is positioned above the transverse moving travelling wheel box set, and is hinged with the transverse moving travelling wheel box set through a hinge pin; and the reverse supporting wheel box and the transverse moving travelling wheel box set are vertical to each other based in space, and are driven through a motor reducing gear. Compared with the prior art, the intermediate supporting mechanism for the bridge girder erection machine of the road, disclosed by the utility model, has the advantages that the reverse supporting wheel box and the intermediate supporting rotating seat are hinged through the hinge pin, so that a girder of the bridge girder erection machine and the intermediate supporting mechanism can be automatically balanced based on the gradient of the working bridge surface; the transverse moving travelling wheel box set and the intermediate supporting rotating seat are hinged through the hinge pin, so that an inclined bridge can be erected by automatically adjusting based on the curve radius of the working bridge surface; and as a result, the intermediate supporting mechanism is higher in adaptability and lower in labor intensity.
Description
Technical field
The utility model relates to a kind of highway bridging machine, particularly relates to support mechanism in a kind of highway bridging machine.
Background technology
Highway bridging machine be a kind ofly move that working range is wide, the highway bridge spanning equipment of function admirable, easy to operate, structural safety.Middle support mechanism is as the support running mechanism of Bridge Erector, in the status of whole Bridge Erector topology layout mesopodium weight.
At present, middle support mechanism major part all adopts U-shaped integrated model, adopts the core dish of adjustable certain angle to connect, and needs to realize by assembling-disassembling bolt the adjustment of angle, not only increases labour intensity, and can not realize automatically regulating the gradient and set up angle.
Summary of the invention
The purpose of this utility model provides support mechanism in a kind of highway bridging machine, can realize the Bridge Erector transverse shifting, automatically regulate the gradient and set up angle.
For achieving the above object, the technical solution adopted in the utility model is:
Support mechanism in the highway bridging machine of the present utility model, comprise anti-support roller case, middle holder rotating seat and traversing traveling roller box group, anti-support roller case and middle holder rotating seat are hinged by bearing pin, middle holder rotating seat is positioned over above the traversing traveling roller box group, hinged by bearing pin, anti-support roller case and traversing traveling roller box group are arranged vertically mutually in the space, and anti-support roller case and traversing traveling roller box group adopt motor reducer to drive.
Compare with prior art, support mechanism in the highway bridging machine of the present utility model adopts anti-support roller case and middle holder rotating seat hinged by bearing pin, can preferably according to the work bridge floor gradient, realize crane ' s major girder and middle support mechanism self-balancing; Adopt traversing traveling roller box group and middle holder rotating seat hinged by bearing pin, can automatically regulate according to service bridge surface curve radius preferably, realize setting up of skew bridge; So applicability is stronger, labour intensity alleviates.
Description of drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is right view of the present utility model.
Among the figure: 1, anti-support roller case, 2, middle holder rotating seat, 3, traversing traveling roller box group, 4, girder.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described.
As depicted in figs. 1 and 2, support mechanism in the highway bridging machine of the present utility model, comprise anti-support roller case 1, middle holder rotating seat 2 and traversing traveling roller box group 3, anti-support roller case 1 is hinged by bearing pin with middle holder rotating seat 2, middle holder rotating seat 2 is positioned over above 3 groups of the traversing traveling roller boxs, hinged by bearing pin, anti-support roller case 1 and traversing traveling roller box group 3 are arranged vertically mutually in the space, and anti-support roller case 1 and traversing traveling roller box group 3 adopt motor reducers to drive.
Girder 4 is positioned on the anti-support roller case 1, and girder drives at motor reducer and realizes the complete machine vertical shift under anti-support roller case 1 roller; Anti-support roller case 1 is hinged by bearing pin with middle holder rotating seat 2, can realize that anti-support roller case 1 regulates voluntarily according to longitudinal grade, makes four anti-support rollers stressed evenly.Middle holder rotating seat 2 is positioned over above the traversing traveling roller box group 3, and is hinged by bearing pin, therefore middle holder rotating seat 2 sets up angle with respect to 3 self-regulations of traversing traveling roller box group, realizes that skew bridge sets up.Traversing traveling roller box group 3 along the cross moving track transverse shifting, realizes that complete machine is traversing under motor reducer drives.
Compare with prior art, support mechanism in the highway bridging machine of the present utility model adopts anti-support roller case 1 hinged by bearing pin with middle holder rotating seat 2, can preferably according to the work bridge floor gradient, realize crane ' s major girder and middle support mechanism self-balancing; Adopt traversing traveling roller box group 3 hinged by bearing pin with middle holder rotating seat 2, can automatically regulate according to service bridge surface curve radius preferably, realize setting up of skew bridge; So applicability is stronger, labour intensity alleviates.
