Boom length adjustable pipe layer according to an embodiment of the present invention shown in Figure 2 to 6,

Lower running body (1);

An upper frame (4) rotatably mounted on the lower traveling body (1), on which an cab cap (2) and an engine compartment (3) are mounted;

A boom adapter (5) mounted to the front of the upper frame (4);

A boom (7) rotated by a boom cylinder (6) having a lower end fixed to the boom adapter (5) by a fixing pin and rotatably fixed by a fixing pin on a lower end of the upper frame (4);

Removably fixed to the first mounting member 13 (upper mount 13a, middle mount 13b, lower mount 13c) of the first center plate 12 installed on the top of the boom 7 A flag block 14 supporting the wire rope 9 by sieve to lift and lower the hook 10;

A winch 11 for elevating the hook 10 by a wire rope 9 wound around the winch roller according to a rotational direction of the winch motor (not shown) mounted on the upper frame 4;

A connecting plate 15 detachably fixed to an upper end of the boom 7, left and right frames 16 and 17 fixed by welding to be opposed to the connecting plate 15, and left and right frames 16 and 17. The second center plate 18 fixed to the opposite surface by welding and the flag block 14 installed on the second center plate 18 and separated from the first mounting member 13 are detachably fixed. A second mounting member 19 (upper mount 19a, middle mount 19b, lower mount 19c) is provided, and is detachably fixed to the top of the boom 7 so that the length of the boom 7 can be fixed. It includes; boom expansion structure 20 to adjust.

In this case, preferably, the connection plate 15

The fixing plate 21 is in close contact with the fixing plate 21 formed on the top of the boom 7 so as to correspond to the connecting plate 15, and is fixed by the bolt 22 fastened through the connecting plate 15 and the fixing plate 21. It can be fixed to the removable.

The left and right frames 16 and 17 are

Each pipe having a cross section corresponding to the cross section of the boom 7 (for example, a square pipe may be used) may be formed.

The boom extension structure 20

Pipe lugs 23 and 24 fixed by welding on the left and right frames 16 and 17, respectively, (for example, four in the figure);

One side is detachably fixed to the upper surface of the boom (7), the other side to the pipe lugs (23, 24) brackets (25, 26) that is foldably connected by a fixing pin (P); And (27).

The brackets 25 and 26

It may be detachably fixed to the upper surface of the boom 7 by bolts 28 that penetrate the brackets 25 and 26 to the upper surface of the boom 7.

At this time, the configuration except for the boom extension structure 20 detachably mounted on the top of the boom (7) in order to stretch and adjust the length of the boom (7) according to the working environment, the configuration of the pipe layer shown in FIG. Since the description is the same, detailed descriptions of these configurations are omitted, and overlapping reference numerals refer to the same configuration.

Hereinafter, an example of using the boom length adjustable pipe layer according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

2 to 6, the boom (7) by the boom expansion structure 20 is detachably connected to the end of the boom (7) during the pipe laying operation to lift the heavy oil pipeline and move to the buried place It is possible to improve work efficiency by extending the working radius by extending the length by a predetermined length.

That is, in a state in which the connecting plate 15 of the boom extension structure 20 is in close contact with the fixing plate 21 formed on the top of the boom 7 to correspond to this, by the fixing pin (P) to the boom extension structure 20 The rotatably hinged brackets 25 and 26 are detachably fixed to the upper surface of the boom 7 by fastening the bolts 28.

The fixing plate 21 at the top of the boom 7 and the connecting plate 15 to be held in close contact therewith are detachably fixed by fastening the bolts 22.

The flag block 14 detachably fixed to the top of the boom 7 is separated. That is, the upper mount 13a, the middle mount 13b, and the lower mount 13c constituting the first mounting member 13 welded to the first center plate 12 fixed to the upper inner surface of the boom 7. The flag block 14 is removed by loosening the bolt (not shown) fixing the flag block 14.

The flag block 14 removed from the first center plate 12 is fixed to the second center plate 18 of the boom extension structure 20. That is, the flag block 14 is fixed to the upper mount 19a, the middle mount 19b, and the lower mount 19c of the second mounting member 19 welded to the second center plate 18 by fixing pins P1. ).

As shown in FIG. 4, the length of the boom 7 may be extended by a predetermined length by the boom extension structure 20 connected to the upper end of the boom 7. In other words, the length of the boom 7 in the state before connecting the boom extension structure 20 to the top of the boom 7 (the fixing pin center and the first center plate 12 hingedly fixed to the bottom of the boom 7 to the boom adapter 5). ) Refers to the distance to the center of the flag block 14 fixed to).

On the other hand, when the boom extension structure 20 is connected to the top of the boom 7, the total length of the boom 7 (the center of the fixing pin and the second center plate hinged to the bottom of the boom 7 to the boom adapter 5) The distance to the center of the flag block 14 fixed to 18) is "L1" + "L2".

Therefore, it is possible to extend the working radius by extending the length of the boom 7 by "L2" according to the working environment.

On the other hand, as described above, when the pipe laying work to extend the length of the boom (7) by the boom expansion structure 20 connected to the top of the boom (7) to lift and carry a heavy pipe, the stability or operability of the equipment Can fall.

That is, in accordance with the working environment or the driver's intention that the work is not required to extend the length of the boom 7, the bolts 22 and 28 fixing the boom extension structure 20 to the upper part of the boom 7 are relaxed. By selectively detaching the boom extension structure 20 by adjusting the length of the boom (7) can be worked.
