Abstract

The utility model discloses a bridge pier beam-removing device, including two rails and beam-moving trolleys respectively arranged on the two rails, wherein, a pushing oil cylinder is connected with each beam-moving trolley; two bearing seats are arranged on the beam-moving trolley on one rail; two communicated thin jack bearing seats are arranged on the beam-moving trolley on the other rail. During the beam-moving working process, a bridging machine falls to the upper part bearing of the beam-moving trolley after the beam is lifted to the target position. As the bearing seats on one beam-moving trolley are replaced by two communicated thin jacks, four bearing seats and three-point supports are achieved, with the three points forming one plane. Thereby, the beam falling to the beam-moving trolley can not be twisted or damaged.

Description

Bridge formation pier Beam shifter

Technical field

The utility model relates to a kind of bridge formation pier Beam shifter.

Background technology

When using single armed bridge formation frame to establish railway, highway bridge, the general employing of the traversing conventional method of beam sheet of pier end face is rolled and is moved, and capital equipment has pallet, slideway, roll shaft, chain block, track jack, jack or hydraulic pressure ejector etc., pure manually-operated, waste time and energy poor stability.Chinese patent ZL91201803.8 discloses a kind of concrete-bridge cross sliding machine, form by two-way seat hook, oil cylinder, fortune beam dolly and guide rail, be applicable to the two framves of single line bridge erection and single shop that the bridge formation machine is can not be traversing in place the multiple line bridge set up in place, can save the labour, reduce labor intensity, operating efficiency more manually improves 3～4 times.But this concrete-bridge cross sliding machine is in moving the beam operation process, and the beam sector-meeting that drops on the fortune beam dolly is twisted impaired because of the bottom surface easily more than supported at three point.

Summary of the invention

The purpose of this utility model provides a kind of beam operation pier Beam shifter of building bridge stably that moves.

For achieving the above object, the utility model adopts following technical scheme: a kind of bridge formation pier Beam shifter, comprise two tracks and lay respectively at and move the beam dolly on two tracks, with move the beam dolly and link to each other and be equipped with pipe bending cylinder, the beam dolly that moves on the described track is provided with two bearings, moves the thin type jacking bracket that the beam dolly is provided with two connections on another track.

The plane is a flute profile on the described track, and the described beam dolly that moves is positioned at this groove, and the sidewall spacers of groove has a plurality of saw tooth base grooves, moves beam dolly two ends and is provided with directive wheel, and pipe bending cylinder one end is hinged on and moves on the beam dolly, and the other end has axle to be positioned at the saw tooth base groove of groove sidewall.

The spacing of adjacent two saw tooth base grooves is not more than the stroke of pipe bending cylinder, and the opening direction of saw tooth base groove is consistent with the direction of advance of pipe bending cylinder.

The utility model is in moving the beam operation process, it is dropped on moves on the beam dolly upper seat, owing to wherein move of the thin type jack replacement of the bearing of beam dolly on one side by two connections, thereby realize four bearings, supported at three point, and plane of 3 formation, the beam sheet that therefore drops on the fortune beam dolly can not twist impaired.

The specific embodiment

As shown in Figure 1, 2, 3, the utility model comprises the cross moving track 1 that lays respectively at two pier 6 inboards, with pull bar 7 itself and pier cap 5 is fixed.Shown in Fig. 2,3,4, the plane is a flute profile on the track 1, has kept flat in this groove 8 and has moved beam dolly 3, moves beam dolly 3 two ends and is provided with directive wheel 9.As shown in Figure 5, the sidewall spacers of groove 8 has a plurality of saw tooth base grooves 10, the cylinder putter 12 of pipe bending cylinder 2 one ends is hinged on and moves on the beam dolly 3, the other end has axle 11 to be positioned at the saw tooth base groove 10 of groove 8 sidewalls, the spacing of adjacent two saw tooth base grooves 10 is slightly less than cylinder putter 12 strokes of pipe bending cylinder 2, and the opening direction of saw tooth base groove 10 is consistent with the direction of advance of pipe bending cylinder 2.As shown in Figure 1, the beam dolly 3 that moves in the track 1 on pier 6 is provided with two

fixed bearings

4,13 therein.As shown in Figure 5, the thin

type jacking bracket

14,15 that is provided with two connections on the beam dolly of moving in the track on another pier; As shown in Figure 6,, form the Communicating device of contacting, in fact just become a fulcrum, control thin type jack 16,16 ' oil inlet and oil return by equalizing valve 19 because bearing 14,15 interconnects two thin type jack 16,16 ' by oil pipe 17.Two fixed

bearings

4,13 that move on thin

type jacking bracket

14,15 and another pier 6 like this on the beam dolly 3 cooperate, and realize four bearings, supported at three point, the unlikely torsional deformation of protection beam body.

Shown in Fig. 1,5, it is dropped on the fixed bearing 4,13 and thin

type jacking bracket

14,15 that moves on the beam dolly 3, utilize pipe bending cylinder 2 to promote to move beam dolly 3, case beam 17 is moved from a side direction opposite side, once move the stroke of an oil cylinder, the oil cylinder of withdrawing then falls in the next saw tooth base groove 10 axle 11, and oil cylinder 2 continues pushing tow.After so step by step case beam 17 being moved among Fig. 1 17 ' position, rise the construction oil cylinder 18 that is placed in advance on the Dun Ding, take over the bearing load that moves on the beam dolly 3, fall thin type jack 16,16 ', vertically pull out and move beam dolly 3, laterally extract cross moving track 1 out, reclaim the construction oil cylinder 18 on the Dun Ding, case beam 17 is dropped on the neoprene bearing.Shift Beam shifter at last and be installed on next bridge pier, carry out next and stride and move beam.
