[0030] A specific embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0031] like Figures 1 to 3 As shown, an embodiment of the present invention provides a boom structure, including a boom 5 and a boom frame, the boom frame including a frame body 1, a mounting frame 2 slidably arranged on the frame body 1, and a lifting mechanism for driving the mounting frame 2 to move up and down; the boom 5 is rotatably arranged on the mounting frame 2, so when the guardrail is not parallel to the guardrail hanging machine, the worker can directly push the guardrail plate to make the boom 5 swing around the rotation point as the center until the guardrail plate is flush with the guardrail, which is convenient for subsequent installation work. In this operation, there is no need for workers to hold up the guardrail plate, thereby saving manpower and improving efficiency;

[0032] This embodiment is also provided with a protective structure to prevent the guardrail from hitting the boom 5, and the protective structure is mounted on the mounting frame 2;

[0033] The lifting mechanism includes a motor 3 and a rack transmission assembly mounted on the frame 1. The rack transmission assembly includes two gear sets 4 that are respectively rotated at the top and bottom ends of the frame 1 and chains mounted on the two gear sets 4. The ends of the chain (not shown in the figure) are respectively connected to the upper and lower sides of the mounting frame 2.

[0034] The motor 3 is used to drive one of the gear sets 4 to rotate, and the mounting frame 2 is lifted and lowered by the forward and reverse rotation of the motor 3, that is, the boom 5 is lifted and lowered;

[0035] In addition, a plurality of mounting holes 6 are provided on the top of the boom 5, a hook 7 is installed in one of the mounting holes 6, and the guardrail plate is hung on the hook 7 by a sling;
