Specifically, the fixed end of the telescopic guide 22 (for example, when the guide bushing 222 and the guide post 221 are used as the telescopic guide 22, the end of the guide post 221 that is stationary relative to the frame and is far from the guide bushing 222 is used as the fixed end) is mounted on the frame of the girder transporting vehicle by a fastening member, and one end of the driver 21 (for example, when the hydraulic cylinder is used as the driver 21, the end of the cylinder body thereof) is relatively fixedly connected to the fixed end of the telescopic guide 22.
When the bridge erecting machine needs to be transported, the girder transporting vehicle and the telescopic transportation bracket device need to be firstly hoisted to corresponding positions, for example, a position between a second column and a first column of the bridge erecting machine needs to be supported, at the moment, the girder transporting vehicle and the telescopic transportation bracket device need to be hoisted to a position between the second column and the first column through a crane trolley of the bridge erecting machine, and certain limitation requirements on the transportation height are caused due to the influence of structures such as a machine arm and a cross beam at the position of the second column.
The girder transporting vehicle of the embodiment supports the bridge girder erection machine through the bracket body 12, and the bracket assembly 1 can adapt to the complex appearance structure of the bridge girder erection machine through the relative rotation between the bracket assembly 1 and the telescopic assembly 2, so that the support stability of the bridge girder erection machine on the girder transporting vehicle is improved; moreover, the telescopic component 2 of the telescopic transfer bracket device is arranged on the frame of the girder transporting vehicle, so that the bracket component 1 can move up and down relative to the girder transporting vehicle, the whole transporting height of the girder transporting vehicle is convenient to adjust, and the girder transporting vehicle can be suitable for complex transporting working conditions with limited transporting height; in addition, the bridge girder erection machine is transported by the girder transporting vehicle, the bridge girder erection machine does not need to be disassembled, the transportation efficiency is improved, and the construction period is saved.
Although the present disclosure has been described above, the scope of the present disclosure is not limited thereto. Various changes and modifications may be effected therein by one of ordinary skill in the pertinent art without departing from the spirit and scope of the present disclosure, and these changes and modifications are intended to be within the scope of the present disclosure.
