Abstract
The utility model discloses a flexible leg anchoring device of a bridge girder erection machine with a single nose girder, which is characterized by comprising a flat plate type pin boss, a draw bar, four hooks and two locking bolts. A support is arranged on the top surface of the flat plate type pin boss, one end of the draw bar is connected with the support through a pin, the four hooks are symmetrically hinged to two sides of the flat plate type pin boss pairwise, and two locking bolts are respectively matched with threaded holes in the middle of the flat plate type pin boss. The flexible leg anchoring device has the advantages that the bridge girder erection machine with a single nose girder is longitudinally anchored on a tool rail by the anchoring device when in use, and the top end of the draw bar of the anchoring device is hinged to a flexible leg, so that longitudinal stability of the bridge girder erection machine can be improved effectively and tipping of the bridge girder erection machine when passing through holes.
Description
Technical field
The utility model has related to a kind of single conducting beam bridge formation machine servicing unit, particularly a kind of single conducting beam bridge formation machine flexible leg anchor device.
Background technology
Single conducting beam bridge formation machine is an equipment commonly used in the present bridge construction, obtained the approval of numerous units in charge of construction with advantages such as its efficient height, good stabilities, DJ180 sections road column single conducting beam railway T type bridge bridge formation machine has 0#, 1#, four cylinders of 2#, 3# support, wherein the 2# post is a rigid leg, 0#, 1#, 3# are flexible leg, in bridge formation machine operation process, during the via hole operation, when prerequisite is moved the 2# post, the bridge formation machine is supported by 0#, 1#, 3# flexible leg, longitudinal stability is poor, very easily causes the bridge formation machine vertically to topple.
