B. often group lifting unit equipment is mainly made up of hoist engine, wire rope, leading block, electric block.
C. until described beam body complete qualified after, carry out as the parent installed of lifting unit equipment the installation work lifting unit equipment using described beam body; First, along on the beam body center line of bridge, installing at both sides beam-ends along the bridge and span centre position respectively can the electric winch of rotating, and they and beam face are connected firmly, secondly, the wire rope of appropriate length is installed to each hoist engine, and in the place that wire rope contacts with beam body, leading block is installed, in the course of the work wear damage is caused to beam body to prevent wire rope, finally, on the wire rope at beam body base plate place, appropriate location is fixedly connected with electric block, and electric block also can be moved left and right when hoist engine rotating thereupon;
D. by above unit equipment, finally realize beam-type support and move left and right bottom bridge beam body, to reach, beam-type support is shifted out beam body base plate position, complete the traversing work of beam-type support, ensure that beam-type support dismounting safety;
E. when often organize beam-type support by traversing below bridge flange plate after, then hung by rubber-tyred lifting machine and fall within ground.
The technical scheme of apparatus of the present invention is: lifting unit equipment is by indulging the spilled water hole anchor ear of bridge direction both sides beam-ends and span centre at Liang Tishang, install three groups of same lifting unit equipments, concrete installation site lays respectively at vertical bridge direction both sides beam-ends and span centre position; Carry out as the parent that lifting unit equipment is installed the installation lifting unit equipment using this beam body; Beam body center line along bridge is installed respectively at both sides beam-ends along the bridge and span centre position can the electric winch of rotating, and they and beam face are connected firmly, to each hoist engine, wire rope is installed, and in the place that wire rope contacts with beam body, leading block is installed, the wire rope at beam body base plate place is fixedly connected with electric block, electric block is also moved left and right when hoist engine rotating thereupon.
The invention has the beneficial effects as follows: the method adopting this bridge base plate position beam-type support entirety laterally to shift out and device, not only greatly can save the beam-type support horizontal time of shifting out bottom beam body, reduce construction cost simultaneously, and greatly can reduce security risk.

Detailed description of the invention
Embodiment 1
Below in conjunction with accompanying drawing, the present invention is described further:
As shown in the figure, wherein, 1 be spilled water hole, 2 are beam bodies, 3 are pier shafts, 4 are bases, 5 are hoist engines, 6 are anchor systems, 7 are leading blocks, 8 are wire rope, 9 are lateral connection, 10 are goosenecks, 11 are beret truss, 12 are steel buttresses, 13 are Sand Buckets, 14 is electric blocks.
Be now that object introduces the overall method that laterally shifts out of this bridge base plate position beam-type support and device with Bailey beam, this device takes full advantage of beam body itself and finishes the work.Its key technical indexes is as follows:
