The inner side of the side plug cylinder 605 is used in cooperation with the side plug rod 604. The enclosure net 606 is fixedly connected between the opposite sides of the first column 602 and the second column 603. By providing the extension connecting plate 601, it is convenient to connect the first column 602 and the carrier 1 of the articulated boom vehicle. The first column 602 cooperates with the second column 603 to connect the enclosure net 606. And the connection between the side plug rods 604 and the side plug cylinders 605 between multiple enclosure nets 606 can facilitate enclosing the working position.

[0040] In this example, a mating insertion ring 7 is fixedly connected to the front side of the carrier 1 of the articulated boom vehicle. The inner side of the mating insertion ring 7 is used in cooperation with the side plug rod 604. By providing the cooperation between the mating insertion ring 7 and the side plug rod 604, it is convenient to connect the carrier 1 of the articulated boom vehicle and the enclosure assembly 6.

[0041] In this embodiment, a connecting flat plate 8 is fixedly connected to the top of the second conical cylinder 505, and the top of the connecting flat plate 8 is fixedly connected to the rotating shaft connecting plate 4. By setting the cooperation of the connecting flat plate 8 and the rotating shaft connecting plate 4, the structure is made more reasonable and the force is more evenly distributed.

[0042] In this embodiment, bottom pads 9 are fixedly connected to the bottoms of the support disk 5072 and the foot disk base 501. The bottom pads 9 are made of rubber material. By setting the bottom pads 9, the damage to the ground can be further reduced when the support disk 5072 and the foot disk base 501 are connected to the ground.

[0043] In this embodiment, a receiving groove 10 is formed on the surface of the foot disk base 501, and the inner side of the receiving groove 10 is used in cooperation with the extension support 506.

[0046] It should be noted that the present invention is a base for an articulated vehicle. First, adjust the hydraulic cylinder 502 to extend, push the first conical cylinder 503 upward. When the first conical cylinder 503 moves upward, it drives the second conical cylinder 505 to move upward through the connecting block 504. At this time, the extension support 506 will extend outward due to the sliding of its own arc-shaped inclined surface in the first conical cylinder 503 and the second conical cylinder 505 and the influence of gravity to increase the support contact area. The force at the top of the rotating shaft connecting plate 4 is transmitted to the extension support 506 by pressing against the bottom of the connecting flat plate 8 and the second conical cylinder 505. The provided leg support assembly 507 can facilitate increasing the force-bearing area of the extension support 506 and further facilitate support.
