Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for transporting bridge structures and similar rigid structures of large weight, while moving them, in larger numbers than would provide the carrying force determined under static conditions. The present invention relates to a method and apparatus for moving the vehicle while supporting it.

The large mutual pressures that occur when moving heavy structures must be distributed over several points.

Current load distribution is carried out by cradle supports which equalize the load in the longitudinal direction rather than in the lateral force direction, which is a disadvantage as far as juxtaposed hk cradle is concerned. be.

This is because the parallel frames must differentially carry most of the K load due to the discrepancy in their dimensions.

A disadvantage, as mentioned above, is that a rigid structure is placed on a plurality of hydraulic jacks distributed in two parts below it and having sliding means at the upper ends facing the structure, and the jacks are For supporting the structure even when the height of the surface of the rigid structure that is in contact with the sliding means provided at the upper end of the jack and that is compressively connected to each other in several groups is changed. are eliminated by the method and apparatus of the present invention, in which the reciprocal forces are uniformly distributed in each group.

The invention also includes the advantage that the hydraulic jacks, unlike the cradle supports, can be spaced a large distance apart in both the longitudinal and lateral force directions.

Although the trestle support requires specially designed bearings, the liquid king jack may be placed on a constructed pier or the like.

The wooden feature of the present invention is that by adjusting the hydraulic pressure of at least one of the several groups of hydraulic jacks, so that the rigid structure moves in the desired force direction by its own weight,
The moving surface, i.e. the supporting surface defined by sliding means provided at the upper end of each hydraulic jack, is tilted so that the rigid structure is appropriately guided in a substantially horizontal force direction. It is.

The method and device according to the invention positively supports bridge structures and similar rigid structures of great weight supported by a plurality of sliding means distributed in groups below the structure. It can also be easily applied when moving to
In such an embodiment of the invention, each sliding means in at least one group is fitted with a driving jack for positively moving said structure, and in said group A drive jack attached to the sliding means for moving the structure is hydraulically actuated.

With such a configuration, each drive jack bears an equal load.

The invention will now be described in more detail with reference to its embodiments with reference to the accompanying drawings, which show a bridge structure to be moved, supported on sliding means arranged below the structure. Explain.

In the figure, 1 indicates a heavy rigid bridge structure to be moved.

In the embodiment illustrated in FIGS. 1 and 2, the bridge structure 1 has a plurality of hydraulic jacks distributed on the pillars 3 of the bridge structure 1 and below the structure. It is located on 2.

The hydraulic jacks 2 have sliding means 4 at their upper ends facing the bridge structure 1, which sliding means are roller carriages in the illustrated embodiment but may also be rollers or slides. It may also be something like motion.

The roller carriage 4 is connected to a hydraulic jack 2 for angular positioning of the carriage in at least two directions.
, so that the roller carriage 4 can always adapt to the mobile and heavy bridge structure 1.

In the illustrated embodiment, the roller carriage 4 described above is used.
The positioning in the angular force direction is effected by a spherical joint 5 provided between the hydraulic jack 2 and the roller carriage 4.

The hydraulic jack 2 can maintain the height of each bridge structure 1 even if there is a height change in the surface of the bridge structure 1 that comes into contact with the roller carriage (sliding means) 4 provided at the -L end of the jack 2. Several groups are hydraulically connected to each other so that the counterforce is evenly distributed to each hydraulic jack in the group.

A source of pressure medium common to each hydraulic jack 2 of a group is designated in the figure by 6, the pressure medium source 6 being able to adjust its hydraulic pressure.

At least some of the roller carriages 4 are provided with control stages 7 which cooperate directly or indirectly with the bridge structure 1 and which effect the directional adjustment of the roller carriages 4.

In the embodiment illustrated in FIG. 3, the bridge structure 1 rests on roller tracks 8 mounted on the columns 3 of the bridge structure 1.

The roller track 8 is connected to the column 3 in such a way that it can be angularly positioned in at least two directions.

The position of the angular force direction of the roller track 8 is determined by the spherical joint 5.

The roller tracks 8 are distributed in several groups 3 under the bridge structure 1, and each roller track 8 in at least one group is fitted with a driving jack 9 for moving the bridge structure 1. The jacks 9 attached to each roller track 8 in the group are operated hydraulically when the bridge structure 1 is moved.

Each jack 9 is connected to a common hydraulic medium source 10 with the other jacks 9 of its group 1; each jack 9 is connected to sliding means formed by roller tracks 8, the driving forces of which are each associated with each other; Preferably, the signal is transmitted directly to the sliding means.

Each jack 9 engages a special connecting means 11, such as a connecting rod or similar member, such as a shirt ring, connected to the bridge structure 1, and by indexing the connecting stages 11, the bridge is The structure 1 may be configured to be actively moved.

However, in such a case the hydraulically actuated jacks 9 in a group arranged in the direction of the traction force (transfer force direction) must be made to engage in a connecting stage 11 common to them ( (See Figure 3).

In the embodiment illustrated in FIG. 4, the bridge structure 1 is arranged in a plurality of liquid king jacks 2L distributed below the structure at the pillar 3-t of the bridge structure 1. ing.

The hydraulic jack 2 is provided with sliding means 12 at each end of the bridge structure 1.

The sliding surface of the sliding means 12 may be made of a self-lubricating material such as deflon, or the sliding surface m1 may be provided with a lubricant such as oil for graphite.

The sliding means 12 are adapted to cooperate directly or indirectly with the underside of the bridge structure 1.

As in the embodiment illustrated in FIGS. 1 and 2, a spherical joint 5 is arranged between the hydraulic jack 2 and the sliding means 12.

Further, the hydraulic jacks 2 are connected in several groups so that the mutual force is evenly distributed in each group.

For this purpose, a group is provided with a pressure medium source 6 common to all jacks of the group.

Also, as in the embodiment illustrated in FIG. Means 1
A jack 9 is attached to 2 so that the fringe structure 1 can be actively moved.

The jacks 9 attached to the sliding means 12 in each group are connected to a pressure medium source 10 common to the group so that they can be hydraulically actuated for moving the bridge structure 1. ing.

Each jack 9 also cooperates with a connecting stage 13.

In a modified embodiment of the invention, the pressure medium sources 6 and 10 of FIG. They may be moved at the same time.

The sliding means 12 distributed in groups below the bridge structure 1 simultaneously act in hydraulic cooperation with the jacks 9 mounted on the sliding means 12 in that group. Although the invention has been described in detail in particular embodiments thereof, the invention is not limited to these embodiments. It will be obvious to those skilled in the art that various modifications and omissions are possible within the scope of the present invention.
