Abstract
The utility model discloses a bridge guiding girder device, and belongs to the field of bridge installation equipment. The device is arranged on a pier or an abutment along the girder direction, and is characterized by comprising a plurality of bailey beams and a bailey beam bent frame. The bailey beams are formed through splicing of a plurality of bailey pieces, the bailey beam bent frame is assembled by the bailey beams, a plurality of parallel sleepers are placed on the bailey beam bent frame, two steel rails are paved on the sleepers, and a trolley capable of moving back and forth along the steel rails is arranged on the steel rails. The device enables installation of long-span girders of a bridge to be convenient.
Description
Technical field
The utility model belongs to bridge erection equipment field, is specially a kind of bridge nose girder device.
Background technology
In the bridge construction, for simple span bridge or drop in beam structure, when span is big, the weight of beam own is bigger, the installation of beam is adopted loop wheel machine to lift comparatively difficulty and maybe can not be finished, and in view of this, is badly in need of a kind ofly reducing the beam servicing unit of the difficulty in the installation process at the scene, the inventor provides a kind of bridge nose girder device, and this case produces thus.
Summary of the invention
The inventor's purpose is to provide a kind of bridge nose girder device, and the installation difficulty of long-span beams is reduced greatly.
In order to reach above-mentioned purpose, the technical solution of the utility model is: a kind of bridge nose girder device, it is placed on bridge pier or the abutment along the beam direction, comprise by the assembled some Bei Leiliang of some shellfish thunder sheets, described some Bei Leiliang are assembled into shellfish thunder beam framed bent, lay some parallel sleepers on the shellfish thunder beam framed bent, be equipped with two one steel rails on the sleeper, the dolly that can move around along rail is installed on the rail.
Further, connect into shellfish thunder beam framed bent by angle steel or channel-section steel between the described adjacent shellfish thunder beam.
Further, the spacing of the described adjacent rail sleepers of spacing of described adjacent rail sleepers is 50cm, sleeper by iron wire with its colligation on Bei Leiliang.
Further, described rail is fixed on the sleeper by railway spike, and the spacing of rail and the wheelspan of dolly equate.
The utility model provides a kind of bridge nose girder device, and is simple in structure, on-the-spot easy for installation, can reduce the installation difficulty of long-span beams greatly.
Description of drawings

Fig. 2 is the utility model partial structurtes enlarged drawings.
Specific embodiment
As shown in Figure 1, what the utility model disclosed is a kind of bridge nose girder device, a kind of bridge nose girder device, it is placed on bridge pier or the abutment along the beam direction, comprise that described some shellfish thunder beams 11 are assembled into shellfish thunder beam framed bent 1, lay some parallel sleepers 2 on the shellfish thunder beam framed bent 1 by the assembled some shellfish thunder beams 11 of some shellfish thunder sheet 111, be equipped with two one steel rails 3 on the sleeper 2, the dolly 4 that can move around along rail 3 is installed on the rail 3.
Further, connect into shellfish thunder beam framed bent 1 by angle steel or channel-section steel between the described adjacent shellfish thunder beam 11; The spacing of described adjacent rail sleepers 2 determines according to the weight of crossbeam, sleeper 2 by iron wire with its colligation on Bei Leiliang 11; Described rail 3 is fixed on the sleeper 2 by railway spike, and the wheelspan of the spacing of rail 3 and dolly 4 equates.
The splicing of shellfish thunder beam 11: shellfish thunder beam 11 usefulness shellfish thunder sheets 111 splice, and according to the size and the weight of girder segment, can adopt individual layer 3 rows, 4 rows or individual layer 5 rows.After with shellfish thunder pin every row shellfish thunder beam 11 being connected earlier, adopt angle steel or channel-section steel that 3 rows, 4 rows or 5 row shellfish thunder beams 11 are laterally connected together again, the spacing between the shellfish thunder beam 11 is determined according to actual conditions.Shellfish thunder beam framed bent 1 upper berth sleeper 2, the spacing of every sleeper 2 determine according to the weight of crossbeam, with the 8# iron wire with sleeper 2 colligations on Bei Leiliang 11.Spread rail 3 on the sleeper 2, fix, put special-purpose dolly 4 then with railway spike.
The installation of shellfish thunder beam framed bent: the installation of shellfish thunder beam framed bent adopts the large-tonnage loop wheel machine to lift, and the crane capacity of loop wheel machine is through calculating the requirement that should be able to satisfy the lifting of shellfish thunder beam framed bent.During lifting, loop wheel machine carries out in place on bridge pier or abutment, adopts two suspension centres that shellfish thunder beam framed bent is sling then and is put into the position of design in advance.After shellfish thunder beam framed bent was put well, two ends can adopt wire rope and bridge pier or abutment to fix.Destroy for preventing that shellfish thunder beam framed bent from producing pier, you portion, good under the nose girder with plank or metal mat.
Beam is installed: after the nose girder installation, can carry out the installation of beam.It is in place in the suitable position of both sides bridge pier or abutment earlier respectively to be specially two loop wheel machines.When a fortune car when beam being transported to a side bridge pier or abutment place in the mode that retreats, one end of beam is hung onto on the dolly and fixing by the loop wheel machine at this place, the other end of slinging then moves to another side with dolly.In the time of near dolly arrives the opposite bank, the loop wheel machine on opposite bank is sling the beam on the dolly and last loop wheel machine is sling beam jointly is put into the position of design.
The foregoing description and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present utility model to its suitable variation or modification of doing.
