Abstract
The utility model relates to a slider that is used for supplementary bridge girder erection machine installation steel case roof beam, including a supporting beam that the level set up, a supporting beam bottom is fixed and is equipped with a plurality of pulleys, a supporting beam both ends top is a vertical welding limiting plate respectively, vertically wears to establish two at least fastening bolt along a supporting beam on every limiting plate. The utility model discloses can solve the problem that the bridge girder erection machine erects the unable direct handle of curve section steel case roof beam, be favorable to accelerating the construction progress.
Description
Technical Field
The utility model belongs to the technical field of the bridge construction, when concretely relates to adopted bridging machine installation steel case roof beam, cooperation bridging machine lifts by crane the slider of steel case roof beam.
Background
The steel box girder has the advantages of high processing speed, light structure and good stress, and is widely applied to bridge construction. When a steel structure bridge on land is constructed, a steel box girder is generally hoisted by adopting hoisting equipment such as a truck crane, a crawler crane and the like; in the cross-line section, in order to avoid influencing the existing line traffic under the bridge, a bridge girder erection machine can be adopted for installing the steel box girder. When the bridge girder erection machine is used for installing the steel box girder, the girder transporting vehicle transports the steel box girder to the lower part of the bridge girder erection machine, and the bridge girder erection machine crown block lifts the steel box girder from the girder transporting vehicle and then moves to the installation position of the steel box girder. However, for the steel box girder of the curved bridge section, the girder transporting vehicle cannot be driven to the lower part of the bridge girder erection machine, and the overhead crane of the bridge girder erection machine cannot directly lift the girder from the girder transporting vehicle, so that the steel box girder needs to be lifted off from the girder transporting vehicle firstly, and then the steel box girder is moved to the lower part of the bridge girder erection machine through the lifting equipment, thereby increasing the working procedures and working hours and influencing the construction efficiency.
Disclosure of Invention
An object of the utility model is to the above-mentioned problem, a slider for assisting bridge girder erection machine installation steel box girder is provided, makes the steel box girder of curved bridge section can adopt bridge girder erection machine to carry to hang the installation smoothly.
The technical scheme of the utility model as follows:
the utility model provides a slide device that is used for supplementary bridging machine installation steel case roof beam which characterized in that: the supporting beam comprises a supporting beam which is horizontally arranged, a plurality of pulleys are fixedly arranged at the bottom of the supporting beam, limiting plates are vertically welded at the tops of two ends of the supporting beam respectively, at least two fastening bolts are longitudinally arranged on each limiting plate in a penetrating mode along the supporting beam, and the front ends of the fastening bolts on the two limiting plates are arranged oppositely.
The utility model discloses simple structure, convenient to use can solve the bridge girder erection machine and erect the unable direct problem of carrying handle of curve section steel case roof beam. When the steel box girder hangs to transporting the roof beam car on, set up slider in advance at the steel box girder towards locomotive end bottom, the steel box girder transports and supports on-the-spot back, one overhead traveling crane of bridge girder erection machine mentions the steel box girder earlier and moves forward towards rear of a vehicle one end, treat when the steel box girder moves the bridge girder erection machine below towards the locomotive end, two overhead traveling cranes carry simultaneously and hang the steel box girder and move to the mounted position, saved process and the time of independent adjustment steel box girder position, be favorable to accelerating the construction progress.

Detailed Description
As shown in fig. 1, fig. 2 and fig. 3, the utility model discloses a supporting beam 1 that a level set up, a supporting beam 1 bottom is fixed and is equipped with a plurality of pulleys 2, a supporting beam both ends top is vertical welding limiting plate 3 respectively, vertically wears to establish two at least fastening bolt 4 along a supporting beam on every limiting plate, and the relative setting of front end of the fastening bolt on two limiting plates.
When the utility model is implemented, the pulley is preferably a universal wheel, which is convenient for sliding and adjusting the angle of the sliding device; the limiting plate 3 can be made of a section of vertically arranged I-steel, two fastening bolts 4 are respectively screwed on two sides of the flange plate of the I-steel facing the middle of the supporting beam, and a stiffening plate 5 is welded between the flange plate facing the end part of the supporting beam and the supporting beam.
As shown in fig. 4 and 5, the utility model discloses during the use, slider places and is close to locomotive one end on the fortune roof beam car, and after steel box girder 6 hung to put on fortune roof beam car 7, steel box girder 6 was in towards the one end bottom sprag of locomotive the utility model discloses an on supporting beam 1, adjustment fastening bolt 4 made the both sides of the tight steel box girder 6 in 4 front end tops of each fastening bolt.
After the beam section is transported on site by the beam transporting vehicle 7, the vehicle is turned around, the tail of the vehicle is located below the rear part of the bridge girder erection machine 8, the two overhead traveling cranes 9 of the bridge girder erection machine 8 move to the upper part of the tail of the vehicle, the front end overhead traveling crane lifts the steel box girder 6 towards one end of the tail of the vehicle firstly and then slowly moves towards the front part of the bridge girder erection machine, as the steel box girder is provided with a sliding device towards the bottom of the head end of the vehicle, the whole steel box girder moves forwards, the angle is adjusted to be parallel to the bridge girder erection machine while the steel box girder moves, when the steel box girder gradually moves towards the lower part of the bridge girder erection machine towards the head end, the overhead traveling crane at the rear end of the bridge girder erection machine lifts the steel box girder towards the head end, then the two overhead traveling cranes move simultaneously, and lifts the steel box.
