Abstract
The utility model relates to an assembled steel box girder sling, which comprises a rectangular frame formed by connecting two crossbeams and two longitudinal girders, wherein each crossbeam comprises two crossbeam end girders, and at least one adjusting girder is connected between the two crossbeam end girders; each longitudinal beam comprises two longitudinal beam end beams, and at least one adjusting beam is connected between the two longitudinal beam end beams; one end of each beam end beam is welded with one end of a longitudinal beam end beam to form a right angle, and flanges are arranged at two ends of each adjusting beam and are connected with the beam end beams and the longitudinal beam end beams through the flanges. The utility model discloses but the field assembly, the size is adjustable, and the commonality is strong, the transportation of being convenient for.
Description
Technical Field
The utility model belongs to the technical field of the bridge construction, a hoist that lifts by crane steel case roof beam is related to, concretely relates to adopt assembled structure, can lift by crane not unidimensional steel case roof beam hoist.
Background
When the steel box girder is hoisted, in order to ensure that the hoisting points are vertically stressed and avoid deformation of the box girder caused by diagonal tension of the lifting lugs, a common method is to hoist the steel box girder by a special hoisting tool according to the distance between the hoisting points of the girder sections. Because the beam sections have different overall dimensions and different distances between hoisting points, the lifting appliance has various specifications and poor universality; and the existing lifting appliance is generally of an integral structure and large in size, so that inconvenience is brought to transportation and storage.
Disclosure of Invention
The utility model aims at the above-mentioned problem, a fabricated steel box girder hoist is provided, adapts to different steel box girder sizes to be convenient for transport, deposit.
The technical scheme of the utility model as follows:
the utility model provides an assembled steel case roof beam hoist, includes the rectangular frame that two crossbeams and two longerons connect into, and 4 apex angle departments of rectangular frame are equipped with lug, its characterized in that: each cross beam comprises two cross beam end beams, and at least one adjusting beam is connected between the two cross beam end beams; each longitudinal beam comprises two longitudinal beam end beams, and at least one adjusting beam is connected between the two longitudinal beam end beams; one end of each cross beam end beam is welded with one end of a longitudinal beam end beam to form a right angle, the lifting lug is welded at the joint of the cross beam end beam and the longitudinal beam end beam, and flanges are arranged at the other ends of each cross beam end beam and the longitudinal beam end beam; flanges are arranged at two ends of each adjusting beam and are connected with the cross beam end beam and the longitudinal beam end beam through the flanges.
The utility model discloses a can connect the equipment through the flange at the job site, the size is adjustable, and the commonality is strong, and application scope is wide, can adapt to not unidimensional steel case roof beam hoist and mount, simultaneously, because single component is small, is convenient for transport, deposit after the dismantlement.
Drawings
Fig. 1 is a schematic plan view of an embodiment of the present invention;
FIG. 2 is a schematic view of a connection structure of a cross beam end beam and a longitudinal beam end beam;
fig. 3 is a schematic view of the structure of an adjusting beam.
Detailed Description
As shown in fig. 1, fig. 2 and fig. 3, the utility model discloses a rectangular frame that two crossbeams and two longerons connect into, 4 apex angles departments of rectangular frame are equipped with the lug. Each crossbeam comprises two crossbeam end beams 1, and at least one adjusting beam 3 is connected between the two crossbeam end beams 1; each longitudinal beam comprises two longitudinal beam end beams 2, and at least one adjusting beam 3 is connected between the two longitudinal beam end beams 2.
One end of each cross beam end beam 1 is welded with one end of one longitudinal beam end beam 2 to form a right angle, the lifting lugs 4 are welded at the joint of the cross beam end beams 1 and the longitudinal beam end beams 2, and flanges 5 are arranged at the other ends of each cross beam end beam 1 and the longitudinal beam end beams 2.
The cross beam end beam and the longitudinal beam end beam are both made of circular steel tubes. The steel box girder is generally a rectangular structure, and the lifting appliance is generally set to be correspondingly rectangular. Therefore, the utility model discloses during the implementation, can with the length of crossbeam end beam 1 sets up to be greater than the length of longeron end beam 2.
The adjusting beam 3 is a steel tube segment with a standard length.
The utility model discloses a crossbeam end beam and longeron end beam weld in advance, and adjust the roof beam at ordinary times for dividing the body structure at ordinary times, therefore occupation space is little, is convenient for transport and deposits. When the lifting tool is used, the lifting tool can be assembled according to the size of the steel box girder to be lifted, and when the size of the steel box girder to be lifted is large, two or more adjusting girders can be connected with the cross beam end girder or the longitudinal beam end girder after being lengthened through flange connection, so that the size of the lifting tool is correspondingly increased.
Claims (2)
