[0044] As Figures 1 - 8 shown, a super-large mobile tower crane disclosed by the present invention includes:

[0045] A transport vehicle 1, with a set of counterweight legs 2 provided on both sides of the bottom of the transport vehicle 1, and multiple counterweight legs 2 of each set of counterweight legs 2 are arranged at intervals along the length direction of the transport vehicle 1;

[0046] An upright arm, one end of the upright arm is hinged to the rear of the transport vehicle 1, and the upright arm and the vehicle body are connected by a hydraulic device 4, and the hydraulic device 4 drives the upright arm to rotate from a horizontal state to a vertical state around the rear of the transport vehicle 1;

[0049] A balance mechanism 8, the balance mechanism 8 is provided on the boom for balancing the torque of the boom.

[0050] The above-mentioned transport vehicle 1 is used to transport the crane and also serves as the support structure of the crane. Since the heavy objects to be lifted are heavy, counterweight legs 2 are provided on both sides of the bottom of the transport vehicle 1, one set is provided on each side, each set includes multiple counterweight legs 2, and the multiple counterweight legs 2 are arranged at intervals along the length direction of the transport vehicle 1, and according to different forces, the interval in the direction of the rear of the vehicle is smaller than that in the direction of the front of the vehicle. The counterweight legs 2 adopt a detachable connection method, which is installed at the bottom of the transport vehicle 1 during the assembly of the crane and removed after the lifting is completed;

[0051] And an infrared level 18 is provided on the connecting rod between the symmetric counterweight legs 2 on both sides for detecting whether the support of the counterweight legs 2 on the vehicle is horizontal.

[0052] Both the upright arm and the boom are assembled in a splicing manner, and appropriate heights and lengths are assembled according to construction requirements;

[0053] Specifically, the upright arm is formed by sequentially connecting multiple upright arm units 3 end to end;

[0054] Each of the vertical arm units 3 includes a first frame 31 in the shape of a hexagonal prism. Inside the first frame 31, there is a concentric second frame 32 in the shape of a hexagonal prism. The side edges at the upper and lower ends of the second frame 32 extend and are connected to the first frame 31 in a clockwise / counterclockwise direction. At the connection points between the first frame 31 and the second frame 32, there are vertical rods 33, and the two ends of the vertical rods 33 are respectively connected and fixed to the upper and lower ends of the first frame 31.

[0055] Adjacent two vertical arm units 3 are detachably and fixedly connected by bolt assemblies and positioning pins.

[0056] The above-mentioned first frame 31 and second frame 32 can be formed by welding multiple support rods, or can be formed by an integrally molded method. The vertical rods 33 can be welded to the first frame 31 and the second frame 32, or can be integrally molded with the first frame 31 and the second frame 32.

[0057] The edge structures at both ends of the first frame 31 and the second frame 32 can extend outward to form edge structures, so that adjacent two vertical arm units 3 can be attached to each other through the edges, and are fixed by bolts on both sides of the two edges, thereby completing the splicing of the two vertical arm units 3.

[0058] In a further embodiment, the splicing in the height direction of the vertical arm unit 3 is specifically achieved through a self-climbing telescopic installation crane 9 provided on the vertical arm.

[0059] The above-mentioned self-climbing telescopic installation crane 9 includes a fixed arm 91. The fixed arm 91 is in a cross-shaped structure, including a vertical part and a horizontal part. At the bottom of the vertical part, there are two clamping assemblies, and at both ends of the horizontal part, there is one clamping assembly respectively. The fixed arm 91 is fixed to the vertical arm through the clamping assemblies. A telescopic arm 92 is slidably connected to the vertical part. At the top of the telescopic arm 92, there are two clamping assemblies. The telescopic arm 92 is fixed to the vertical arm through the clamping assemblies. A driving motor is provided between the telescopic arm 92 and the fixed arm 91 to drive the telescopic arm 92 to lift along the fixed arm 91. An installation assembly 93 is installed at the top of the telescopic arm 92.

[0060] The above-mentioned fixed arm 91 has a cross-shaped structure. The fixed arm 91 includes a horizontal part and a vertical part. At the bottom of the vertical part, there are two clamping components. The two clamping components are symmetrically arranged along the midpoint of one side of the first frame 31 to ensure the stability of the fixation of the fixed arm 91. The height of the fixed arm 91 is higher than that of the first frame 31, and the horizontal part is fixedly connected to the upper position of the fixed arm 91 (the distance from the bottom of the fixed arm 91 is slightly less than the height of the first frame 31). At both ends of the horizontal part, there are clamping components. The distance between the two clamping components is equal to the side length of the first frame 31, and it can clamp on two adjacent vertical poles 33 of the first frame 31. The telescopic arm 92 is slidably connected to the fixed arm 91, and a driving motor is arranged between the telescopic arm 92 and the vertical part of the fixed arm 91 to drive the telescopic arm 92 to move up and down along the fixed arm 91. At the inner top of the telescopic arm 92, there are two clamping components. The telescopic arm 92 can clamp on the upper and lower edges of the first frame 31 through the clamping components, and an installation component 93 is arranged at the top of the telescopic arm 92 for hoisting the vertical arm unit 3.

[0062] The above-mentioned vertical arm installation crane 931 is arranged at the top of the vertical arm. The vertical arm can be hoisted by the vertical arm installation crane 931. The vertical arm installation winch 932 and the reducer are arranged at the top of the telescopic arm 92 to control the operation of the vertical arm installation crane 931;

[0063] The specific working principle of the vertical arm installation is as follows: First, fix the first vertical arm unit 3 to the mounting seat of the transport vehicle 1 with bolts. Then, clamp the fixed arm 91 of the self-climbing telescopic installation crane 9 to the bottom crossbar of the first vertical arm unit 3 through two clamping components at the bottom. Next, clamp the clamping components at both ends of the horizontal part to the vertical pole 33 of the first vertical arm unit 3. Then, drive the telescopic arm 92 to rise to a suitable position by the drive motor. Then, control the vertical arm installation hoist 932 to lift the vertical arm installation crane 931 to hoist the second vertical arm unit 3 and place it on the first vertical arm unit 3 for installation. Then, control the two clamping components at the top of the telescopic arm 92 to clamp on the edge at the top of the second vertical arm unit 3 by the drive motor, control the four clamping components on the fixed arm 91 to open, and control the fixed arm 91 to rise to the position of the second vertical arm unit 3 by the drive motor, so that the two clamping components at the bottom of the fixed arm 91 correspond to the bottom crossbar of the second vertical arm unit 3, and fix the four clamping components on the fixed arm 91 to the second vertical arm unit 3. Then, drive the telescopic arm 92 to rise and hoist the third vertical arm unit 3, and repeat the above steps until the vertical arm is installed to a suitable height.

[0064] When the height of the above-mentioned vertical arm reaches 100 meters, use four cables in one layer; when it reaches 150 meters, use four cables in two layers; when it reaches 200 meters, use four cables in three layers.
