However, the conventional outrigger has the following problems.

1) The horizontal outgoing beam is usually composed of two or three stages depending on the size of the heavy equipment. In the case of the three-stage horizontal outgoing beam, the outgoing beam having the largest cross section is drawn out first except the fixed beam fixed to the heavy equipment. The drawing beams having a small cross section are sequentially operated to draw out horizontally.

2) Due to this withdrawal structure, it takes a lot of time to set up the initial position of the heavy equipment and its preparation, and it also requires more work for the withdrawal after work.

3) There is a risk of an accident because the fluid supply pipe for supplying fluid to the jack cylinder for operating the vertical extraction beam is exposed outside the outrigger.

4) That is, high pressure hydraulic oil splashes in all directions due to breakage of the fluid supply pipe, which may cause a safety accident. In addition, when designing heavy equipment, there is a problem that the design should be designed in consideration of the interference between the fluid supply pipe and heavy equipment or other components.

5) In addition, in order to extend the fluid supply pipe to the end of the vertical extraction beam, a separate installation space is required, resulting in a problem that the space utilization of the entire heavy equipment is reduced.

In addition, the first guide grooves 532a are formed in two, and each of the first guide grooves 532a has wires 510a and 510b for the stable operation of the variable length stage 500. Do. In addition, the two first guide grooves 532a may be formed on the left and right sides of the second guide grooves 532b as shown in FIG. 3 so that the operating force of the wires 510a and 510b can be evenly distributed. .

The first turning roller 532 is configured to change the direction of the wires (510a, 510b). That is, the wire 510a, 510b in the case of one line or two lines, the one end is installed on the fixed end side of the actuator 520 is wound on the first turning roller 532 second turning member ( 500). As a result, the wires 510a and 510b are wrapped in the longitudinal direction of the actuator 520 while one end is fixed as shown in FIG. 1.

The auxiliary roller 533 is installed below the first turning roller 532 to move along the inner circumferential surface of the inner beam 400. That is, when the actuator 520 moves, the length is changed. In this case, the auxiliary roller 533 is in contact rotation with the inner circumferential surface of the inner beam 400. In particular, the pipe guide groove (533a) is formed in the center of the auxiliary roller (533). The pipe guide groove 533a is moved along the fixing pipe 411b of the fluid supply pipe 411. That is, as shown in Figure 1, the fixed tube (411b) is installed along the center of the guide guide 540 and the inner bottom surface of the inner beam 400, the inner side of the inner beam 400 is connected to the jack cylinder 410. At this time, the pipe guide groove (533a) is to guide the first direction switching member 530 to avoid interference while moving along the fixed tube (411b).

The guide guide 540 is installed inside the bottom surface of the inner beam 400, as shown in FIG. In particular, the guide guide 540 has a connector function that connects the flexible pipe 411a and the fixed pipe 411b constituting the fluid supply pipe 411 described above. In addition to such a function, it has a function of fixing the wires 510a and 510b.

The guide guide 540 is fixed to the plate-like member having a predetermined size by using a method such as fusion or fastening perpendicularly to the bottom surface of the inner beam 400. In particular, the guide guide 540 is fixed to the wire 510 in the center portion. And, one side is provided with a connector 541 for connecting the flexible pipe (411a) and the fixed pipe (411b).

The second turning member 550 is a kind of roller, and the guide groove 551 is formed on the outer circumferential surface thereof so that the wires 510a and 510b can be wound. In particular, the guide groove 551 is used to form one or two according to the number of wires to be used in the present invention.

The second turning member 550 is rotatably installed inside the bottom surface of the middle beam 300, in which case the rolling hole 320 can be rolled in contact with the bottom surface of the inner surface of the outer beam 200. It is desirable to install so that.

The second turning member 550 installed as described above redirects the wires 510a and 510b, which are changed in the first direction by the first turning member 530. In this case, the wires 510a and 510b wound on the second turning member 550 pass through the rolling holes 320 and as described above, the outer beam 200 through the gap G generated by the protrusions 210 and 310. And passes between the inner beam 300 and is fixed to an end side of the outer beam 200.

The four outriggers OT1 to OT4 thus constructed can be used as an example, as shown in FIG. That is, the front left and right outriggers OT1 and OT2 are installed so that the outer beams 200 overlap, but the jack cylinder 410 faces outward. In this manner, the rear left and right outriggers OT3 and OT4 are provided in the same manner.
