Abstract
The invention discloses a kind of jack and jacking apparatus for bridge jacking, the jacking apparatus includes jack, is used to support the support member of the jack, the jack includes cylinder body and piston rod, the upper end of the cylinder body is equipped with the ring flange with screw hole, and the support member, which includes horizontal hanging plate, is fixed on hanging plate side extends downwardly and the fixed plate equipped with screw hole and the bearing that is fixed in fixed plate.As a result of support member on bridge pier can be fixed in the present invention, reliable support can be provided convenient for jack, in bridge jacking construction, as a result of limiting plate, when even if bridge generates transverse shifting during jacking, also it can guarantee that the stabilization of jack is not toppled over, to avoid safety accident.Jacking apparatus of the present invention and method are constructed for bridge jacking, have many advantages, such as safe, efficient, mitigation labor intensity, attenuating construction cost.
Description
Technical field
The invention belongs to bridge construction device and methods, and in particular to a kind of jack and jacking dress for bridge jacking
It sets.
Background technology
It is often required to lay new road surface again on original road surface in road especially highway improvement project, in this way
The height that certainly will will increase road surface, causes the head room for the bridge being erected on road to decrease below design height, therefore must
Bridge must be raised using Lifting Equipment.Lifting Equipment generally uses Special jack, but due to jack in jack-up construction
Unreasonable structure, frequent occurrence jack place the unstable safety accident toppled over.
Invention content
The object of the present invention is to provide a kind of jack and jacking apparatus for bridge jacking.
Realizing the technical solution of the object of the invention is:
Provided by the present invention for the jack of bridge jacking, including cylinder body and piston rod, the upper end of the cylinder body is equipped with band spiral shell
The ring flange in hole.
Provided by the present invention for the jacking apparatus of bridge jacking, including the jack, it is used to support the jack
Support member, the support member, which includes horizontal hanging plate, is fixed on hanging plate side extends downwardly and the fixation equipped with screw hole
Plate and the bearing being fixed in fixed plate(Also known as bracket).
It further include the limiting plate being fixed in the fixed plate for limiting cylinder body of the jack or so.
The limiting plate uses angle steel, angle steel to be equipped with screw hole corresponding with the screw hole in the fixed plate, the angle steel
It is fixed by screws in the fixed plate.
Beneficial effects of the present invention:
As a result of support member on bridge pier can be fixed in the present invention, it is convenient to reliable support is provided for jack,
In bridge jacking construction, as a result of limiting plate, even if when bridge generates transverse shifting during jacking, also it can guarantee
The stabilization of jack is not toppled over, to avoid safety accident.Jacking apparatus of the present invention and method are constructed for bridge jacking,
Have many advantages, such as safe, efficient, mitigation labor intensity, attenuating construction cost.
The technical solution further illustrated the present invention below in conjunction with the accompanying drawings.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the vertical view of Fig. 1.

Specific implementation mode
See Fig. 1 to Fig. 3, provided by the present invention for the jacking apparatus of bridge jacking, including jack, be used to support it is described
The support member of jack, the jack include cylinder body 1 and piston rod 9, and the upper end of the cylinder body 1 is equipped with the method with screw hole 10
Blue disk 2, the support member, which includes horizontal hanging plate 7, is fixed on 7 side of hanging plate extends downwardly and the fixed plate 5 equipped with screw hole
With the bearing being fixed in fixed plate 5(Also known as bracket)4;Further include being fixed in the fixed plate 5 to be used for the jack
Cylinder body 1 or so limit limiting plate 3, the limiting plate 3 use angle steel, angle steel be equipped with and the screw hole in the fixed plate 5
Corresponding screw hole, the angle steel are fixed on by swell fixture 6 in the fixed plate 5.
Bridge c is supported on by cushion block b on bridge pier a under normal circumstances, as shown in Figure 1.When jacking bridge construction, elder generation is needed
Installation jacking apparatus of the present invention, is shown in Fig. 1 to Fig. 3, the hanging plate 7 of support member is hung over to the top of bridge pier a, with swell fixture 6 from
Screw hole in fixed plate 5, which passes through, is fixed on fixed plate 5 on bridge pier a, and the cylinder body 1 of jack is placed in bearing(Also known as bracket)4
Above and between two limiting plates 3, the screw hole 10 on 1 upper flanges disk 2 of cylinder body is passed through with screw 8, by ring flange 2 and support portion
The hanging plate 7 of part connects.Then jack is operated, is jacked bridge c to desired height by piston rod 9, in bridge c and bridge
Support construction a between place new cushion block d bridge c made to obtain new support, as shown in Figure 4.
