[0125] (1) Preparation stage: The staff is required to place the first section lifting assembly 1, the second section lifting assembly 2, the lifting mechanism 3, the support base assembly 6 and the driving device 7 on the ground according to the preset position, and then connect the first upper base 16 of the first section lifting assembly 1 with the second lower base 25 of the second section lifting assembly 2 by bolts, connect the frame door 22 with the second support frame 21 by bolts, and connect the mobile base 63 with the auxiliary support base 62 on the main support base 61 by bolts. At this time, the driving device 7 is in a state perpendicular to the base, the driving end of the driving device 7 is not extended, and the first section lifting assembly 1, the lifting mechanism 3 and the second section lifting assembly 2 are all in a horizontal state;

[0126] (2) The device is in the standing stage: the driving end of the driving device 7 is extended, and the first section lifting assembly 1, the lifting mechanism 3 and the second section lifting assembly 2 are all raised from the horizontal state to the vertical state, and the lifting support member 38 is located between the plurality of supporting protrusions 633, and the upper surface of the lifting support member 38 is lower than the upper surface of the plurality of supporting protrusions 633, and then the second connecting member 13 is removed;

[0127] (3) Lifting stage of the holding rod 9: The first holding rod section is conveyed into the first installation cavity of the first lifting assembly 1 by the conveyor belt 8, so that the first holding rod section is placed on the supporting protrusion 633, and the driving end of the lifting drive device 36 begins to extend, and the lifting support member 38 is driven to move upward through the chain 37. The lifting support member 38 lifts the first holding rod section and moves upward, and the driving end of the lifting drive device 36 continues to extend until the two first climbing claws 42 members clamp the top of the first holding rod section, and then the driving end of the lifting drive device 36 begins to retract, so that the holding rod 9 lifting support member 38 returns to the initial position;

[0128] The second arm is then sent in, so that the side parts of the tops of the four supporting angles of the second arm are against the first positioning arm wheel 15, the driving end of the lifting drive device 36 begins to extend, and the lifting support component 38 lifts the second arm to move upward. When the top of the second arm contacts the bottom of the first arm, the driving end of the lifting drive device 36 is temporarily stopped. Then, after the staff connects the first arm with the second arm by bolts, the driving end of the lifting drive device 36 continues to extend until the two first climbing claws 42 components clamp the top of the second arm, and the driving end of the lifting drive device 36 stops extending, and the driving end of the lifting drive device 36 is retracted, so that the lifting support component 38 returns to the initial position, and the above operation is repeated until all the arms 9, such as eleven arms 9, are lifted. Of course, the total number of arms 9 is not limited to this, and can also be less than eleven arms 9, or greater than eleven arms 9, etc., depending on actual needs.

[0129] (4) Lifting frame dismantling stage: First, the staff needs to remove the bolts connecting the frame door 22 and the second support frame 21, remove the frame door 22 first, and then remove the lifting support member 38. After that, the driving device 7 begins to retract and the entire device is laid down. After being laid down, each part can be removed in turn, for example: remove the bolts connecting the mobile base 63 and the auxiliary support base 62, and pull out the mobile base 63, thereby realizing the overall dismantling.

[0130] It can be seen that the present application proposes a boom lifting device, which has the advantages of light weight, high safety in use, and simplicity and convenience. It is particularly suitable for ground operation of a suspended boom 9 with a cross-section of 700 mm and an overall height of m (of course, not limited to this), and can realize the lifting of the boom from the bottom section by section to the overall height during assembly construction, thereby solving the problem of difficulty in boom assembly construction in complex terrain, improving the safety and work efficiency of assembly construction, and reducing the labor intensity of construction personnel.
