[0022] The following will be further described in conjunction with the drawings and specific embodiments:

[0023] In order to enable the articulated boom truck to work stably and prevent it from tilting or sliding, this embodiment provides a leveling steel base for supporting the articulated boom truck. The leveling steel base is fixedly installed on the slideway to build a working platform for the articulated boom truck, thereby ensuring the stability of the articulated boom truck and preventing it from tipping over.

[0024] The leveling steel base includes a base, an upper panel, supports, diagonal supports, a parking wedge 28, etc. The supports and diagonal supports are both arranged on the base. Multiple supports with different lengths are distributed along the length direction of the base, and their tops gradually rise. The upper panel is installed on the tops of the multiple supports and is inclined. A parking wedge 28 is arranged on the upper panel. The parking wedge 28 is wedge-shaped, and its upper surface is an arc structure. When using this device, the base is directly installed on the slideway, and the upper panel is almost in a horizontal state. Such installation can realize the construction of the working platform of the articulated boom truck. After the articulated boom truck is placed on the upper panel, the parking wedge 28 is placed at the tire of the articulated boom truck to increase the resistance to the movement of the articulated boom truck.

[0025] In order to manufacture a base with greater strength, the base includes a first base main beam 1, a second base main beam 2, a first base cross beam 3 and a second base cross beam 4. The first base main beam 1, the second base main beam 2, the first base cross beam 3 and the second base cross beam 4 form a rectangular frame. The length and width of this rectangular frame are both larger than the length and width of the top view projection of the upper panel, increasing the contact surface between the device and the slideway and enhancing the stability of the device.

[0026] First base secondary beams 5, second base secondary beams 6, third base secondary beams 7 and fourth base secondary beams 8 are arranged at intervals within the rectangular frame. The first base secondary beams 5, the second base secondary beams 6, the third base secondary beams 7 and the fourth base secondary beams 8 are all parallel to the base cross beams and are fixedly connected to the base main beams, increasing the stability of the frame structure.

[0027] A plurality of limit holes 29 are arranged on both the first base main beam 1 and the second base main beam 2. Post-embedded anchor bolts are installed at the limit holes 29 to fix the base to the slideway surface, so as to enhance the friction between the base and the ground and prevent the base from moving and sliding.

[0028] To stably set the upper panel on the base, the supports include the first support 9, the second support 10, the third support 11, the fourth support 12 and the fifth support 13, which are sequentially distributed along the length direction of the base. The first support 9 is the longest and the fifth support 13 is the shortest. The first support 9, the second support 10, the third support 11, the fourth support 12 and the fifth support 13 are all below the upper panel. By length conversion, the upper panel forms a certain slope to bear the vertical component of the working load of the articulated boom lift and enhance the bearing capacity. The lower ends of the first support 9, the second support 10, the third support 11, the fourth support 12 and the fifth support 13 are respectively connected to the first base cross beam 3, the first base secondary beam 5, the second base secondary beam 6, the third base secondary beam 7 and the fourth base secondary beam 8.

[0029] The first support 9, the second support 10, the third support 11, the fourth support 12 and the fifth support 13 are arranged in parallel, and the included angle with the base is set to 55 °.

[0030] Above the base, there are the first diagonal support 14, the second diagonal support 15 and the third diagonal support 16. The first diagonal support 14 is obliquely arranged between the first support 9 and the second support 10, forming a triangular structure to prevent the first support 9 and the second support 10 from being bent under force and enhance their bearing capacity. The tops of the second diagonal support 15 and the third diagonal support 16 are respectively connected to the second support 10 and the fifth support 13, and the bottoms are connected to the base; the included angle between the second diagonal support 15 and the base is set to 65 ° to increase the structural stability and anti-overturning ability and share and transfer the lateral load.

[0031] To enable the upper panel to stably support the articulated boom lift, the upper panel includes parallel first upper panel main beams 17 and second upper panel main beams 18, and also includes parallel first upper panel cross beams 19 and second upper panel cross beams 20. The first upper panel main beams 17, the second upper panel main beams 18, the first upper panel cross beams 19 and the second upper panel cross beams 20 form an inclined frame. Inside the frame, there are first upper panel secondary beams 21, second upper panel secondary beams 22, third upper panel secondary beams 23, fourth upper panel secondary beams 24, fifth upper panel secondary beams 25 and sixth upper panel secondary beams 26 stacked up and down as a grid. The upper panel round steel 27 is welded to form a flat and strong beam grid form, which is convenient for the articulated boom lift tires to be placed. Through the cooperation of the vertical support and the diagonal support, the panel and the bottom base are at 33°, for the horizontal parking of the articulated boom lift with a large slope slideway, ensuring the clarity of the force transmission path and reducing stress concentration. The second upper panel cross beam 20 is embedded in the second base cross beam 4, and the lap joint position is welded.

[0032] Above the secondary beam, there are multiple upper panel round steels 27 arranged along the length direction of the frame to increase friction and prevent the tires from rolling. The parking wedge 28 is made of rubber material, and its lower bottom surface cooperates with the upper panel round steel 27 to increase the contact surface between the tire and the upper panel, increase friction, and effectively prevent the boom truck from sliding or moving during the force application process. Additionally, parking wedges 28 are placed in front of and behind the boom truck tires to prevent the boom truck from rolling forward and backward during operation under force.

[0033] The above is only the preferred implementation manner of the present utility model and is not used to limit the present utility model. For those skilled in the art, various changes and modifications can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
