Telescopic transfer bracket device and beam transporting vehicle

Abstract

The invention provides a telescopic transfer bracket device and a girder transporting vehicle, and relates to the technical field of engineering machinery, the telescopic transfer bracket device comprises: a bracket assembly suitable for supporting a bridge girder erection machine; and the telescopic assembly is located below the bracket assembly and rotationally connected with the bracket assembly so that the bracket assembly can rotate around the horizontal axis, and the telescopic assembly is suitable for being installed on a frame of the beam transporting vehicle and suitable for driving the bracket assembly to do lifting motion through telescopic motion. The heights of supporting points at different positions of the bridge girder erection machine may be different, the bridge girder erection machine is supported through the bracket body, the bracket body can rotate relative to the rotating joint through rotatable connection of the adjusting joint and the rotating joint, supporting at different positions of the bridge girder erection machine is achieved, and the supporting stability of the bridge girder erection machine is improved; the height of the bracket assembly can be adjusted to adapt to transfer working conditions under different transportation heights; the bridge girder erection machine is supported, and rapid transfer can be achieved without disassembling the bridge girder erection machine.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a telescopic transfer bracket device and a beam transporter. Background technique [0002] In recent years, with the gradual increase in the number of bridges in our country, bridge erection machines have been widely used. Because the erection lines of bridges are usually relatively long, the bridge erection machine often needs to be transferred during construction, so it is necessary to transfer the bridge erection machine. [0003] At present, when the bridge erection machine needs to be transferred, the bridge erection machine is generally disassembled first, and then the parts of the bridge erection machine are transferred separately, and then assembled after the transfer is in place. Such a transfer process is extremely time-consuming and can delay construction schedules. If the bridge erection machine is not disassembled, but is directly supported and trans...

Such a transshipment process is extremely time-consuming and may delay the construction period

If the bridge erecting machine is not disassembled, but directly supported and transported by the beam transporter, on the one hand, the complex shape and structure of the bridge erecting machine is not easy to support, and it will be difficult to guarantee the support stability of the bridge erecting machine; On the one hand, the transport height of the bridge erecting machine is difficult to adjust, and cannot be applied to working conditions of different transport heights
