Description
Technical Field
The utility model relates to a slope adjusting device for pushing a steel beam with a variable height section of a bridge, and belongs to the technical field of bridge engineering.
Background
In the large-scale bridge construction, the pushing construction of a steel beam is involved, during pushing, a distribution beam at the top of a walking machine is attached to the bottom of the steel beam, and the friction force between contact surfaces provides the pushing force for the movement of the steel beam. Because the vertical section line type at the bottom of the steel beam with the variable height section is a parabola, the bottom surface of the steel beam and the horizontal plane always have a variable slope in the pushing process. Because there is the slope change, when traditional walking machine pushed away, jack top part distribution roof beam can't guarantee to laminate with the girder steel bottom surface all the time, also can not guarantee that contact surface frictional force is stable, can't provide stable jacking force.
SUMMERY OF THE UTILITY MODEL
Aiming at the problems, the utility model provides a slope adjusting device for pushing a steel beam with a variable height section of a bridge, which has the specific scheme that:
the utility model provides a bridge becomes accent slope device that high cross-section girder steel pushed away, includes base and distribution beam, and the base is used for being connected with the jack top, and the distribution beam is used for supporting the girder steel, the base includes a spherical recess, and it is provided with the spherical crown to slide in the spherical recess, and the spherical crown is connected with the distribution beam.
Furthermore, a wedge-shaped block is arranged at the top of the distribution beam.
Furthermore, a rubber cushion block is arranged at the top of the wedge-shaped block.
Furthermore, the wedge-shaped block comprises a bottom plate and a top plate, the bottom plate is located on one side of the distribution beam, the top plate is located on one side of the rubber cushion block, the top plate is obliquely arranged relative to the bottom plate, and a vertical web plate is connected between the top plate and the bottom plate.
Furthermore, the wedge angle of the wedge-shaped block is 2-3 degrees.
The utility model can utilize the spherical crown device and the wedge block for customizing the gradient to adapt to the gradient change, so that the pushing force holding point is always closely attached to the bottom of the steel beam, the friction force of the contact surface is ensured to be stable, and the stable pushing force can be provided.

Detailed Description
The following describes the embodiments of the present invention in detail with reference to specific examples.
Example 1
As shown in fig. 1-3, a slope adjusting device for pushing a high-section steel beam of a bridge comprises a base and a distribution beam 2, wherein the base is used for being connected with the top of a jack, the distribution beam 2 is used for supporting the steel beam, the base comprises a spherical recess, a spherical crown 1 is arranged in the spherical recess in a sliding mode, and the spherical crown 1 is connected with the distribution beam 2. In this embodiment, the base is formed by directly forming a spherical recess in the top of the jack, and disposing the spherical crown in the spherical recess of the jack.
The top of the distribution beam 2 is provided with a wedge-shaped block 3. The quantity of wedge can set up one deck or two-layer according to girder steel bottom slope size.
The adjustable slope of walking machine top spherical crown 1 device is 0~5%, and equipment self adaptation matches the steel box girder contained angle change in this scope promptly, adds one deck wedge 3 and can adapt to the slope change of 4% ~9%, adds two-layer wedge 3 and can adapt to the slope change of 8% ~ 13%. The wedge-shaped block is formed by welding a top plate 5, a bottom plate 6 and a web plate 7, the thickness of a panel is 12mm, the thickness of the web plate is 16mm, and a rubber cushion block 4 with the thickness of 1cm is attached to the top plate to ensure the friction force of a contact surface. The angle of the wedge-shaped block and the angle of the spherical crown are used for adapting to the beam bottom angle in the whole pushing process, so that the top distribution beam of the pushing equipment is always attached to the beam bottom.
