JPS5930007Y2 - Self-propelled gantry work machine - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to a self-propelled gantry type work machine.

For example, when working on elevated railways, auxiliary lines are laid along the main line (existing line), and temporary auxiliary lines are used to ensure that trains can run off-time, such as late at night.

It is desirable that the work equipment used for such work should be one that does not interfere with train movement even when it is on the work site, one that can maintain a stable posture without being affected by rail conditions, and one that can be easily moved. .

The present invention proposes a self-propelled portal type working machine that can fully satisfy the above conditions, and an embodiment thereof will be described below based on the drawings.

In Figs. 1 to 3, 1 is a workbench with a pair of front and rear main elevating legs 2A, 2B in the center, and a main line (
A traveling device 4 for the rail) 3 is provided.

Reference numerals 5A, 5B, 5C, and 5D are sub-elevating legs, and a pair of front and rear legs are provided on each side of the workbench 1, and a traveling device 7 for a temporary auxiliary line (rail) 6 is provided at the lower end of these legs.

8A and 8B are the main lifting legs 2A. Jack up device that raises and lowers 2B, 9A, 9B.

9C and 9D are jack up devices that raise and lower the sub-elevating legs 5A, 5B, 5C, and 5D;
, 5B, 5C, and 5D can be raised and lowered individually.

As shown in FIGS. 5 and 6, the traveling devices 4 and 7 are swinging devices attached via horizontal shafts 10 to the lower ends of the lifting legs 2 A, 2 B, 5 A, 5 B, 5 C, and 5 D. It consists of a frame 11 and a plurality of wheels 13 attached to the swing frame 11 via a rotation shaft 12, and the rotation shaft 12 is connected to a drive device (not shown) attached to the swing frame 11. ) is linked and linked.

The self-propelled gantry type work machine with the above configuration is assembled on a site with sufficient space or on the railroad track late at night.

Then, one run is made to the destination (site), but at this time, even if the temporary auxiliary line 6 is used as shown in Figures 1 and 3, the main line 3 is used as shown in Figure 4. Furthermore, both lines 3 and 6 may be used simultaneously.

After arriving at the destination, operate the jack up devices 9A to 9D as shown in FIGS. 1 and 3 to lower the auxiliary lifting legs 5A to 5D.
is lowered, and the traveling device 7 is made to land on the temporary auxiliary line 6.

Then, the jack-up devices 8A and 8B are activated to raise the elevating legs 2A and 2B, and the traveling device 4 is separated from the main line 3.

The main elevating legs 2A and 2B are raised to a space on the main line 3 where trains can run, and in this state foundation work for the main line 3 is started.

When there is a level difference between the temporary auxiliary lines 6 on both sides during this foundation work, the sub-elevating legs 5A, 5G or 5B, 5D on either side are raised and lowered to stabilize the work platform 1.

After completing work within the movement range using the sub-elevating legs 5A to 5D, the vehicle travels to the next work site in that state.

However, the foundation or hole for the elevated structure becomes an obstacle and the sub-elevating leg 5A
5D, as shown in Figure 4, the main elevating legs 2A and 2B are lowered and landed, and then the auxiliary elevating legs 5A to 5D are raised and separated. Lifting legs 2
Run using A and 2 B.

After arriving at the target work site, the sub-elevating legs 5A to 5D are lowered again and landed, and the main elevating legs 2A and 2B are raised and separated to move on to the intended foundation work.

By repeating this work, the foundation work will be gradually completed.

In such a situation, the temporary auxiliary line 6 may be used to enable trains to run.

FIGS. 7 and 8 show another embodiment in which rollers 14 are used instead of wheels 13 as the traveling device 7 for the sub-elevating legs 5A to 5D.

According to the present invention described in the examples above, by raising and lowering both the main and sub-lifting legs and selectively using the main line and the temporary auxiliary line, it is possible to move to the destination regardless of various obstacles. It is possible to make it possible for trains to run at the destination,
Furthermore, by raising and lowering the lifting legs individually, it is possible to quickly deal with differences in rail conditions, ie, level differences between the main line and temporary auxiliary lines, and the workbench can be kept level at all times, ensuring safe work.
