[0055] Refer to the following Figures 1 to 18 A mobile self-folding and self-elevating boom according to some embodiments of the present application is described.

[0056] See also Figures 1 to 18 As shown, an embodiment of the present application provides a mobile self-folding and self-lifting boom, comprising: a crawler body 1 and a boom; wherein the boom is folded and arranged in a horizontal state on the crawler body 1, and the crawler body 1 is used to transport the boom to a work site; the boom comprises a folding drive mechanism 2, an inverted frame 3, a heightening assembly, a lifting drive device 17, a slewing mechanism 5, a flipping drive mechanism 6, a mast section 7, a main arm 8 and an unfolding drive mechanism 9; wherein the inverted frame 3 is connected to the crawler body 1 through the folding drive mechanism 2, and the folding drive mechanism 2 is used to drive the inverted frame 3 to be transformed from a horizontal state on the crawler body 1 to an upright state located on the side of the crawler body 1;

[0057] The heightening assembly includes a tower section 4 and a waist ring 16. The number of heightening assemblies is multiple and they are arranged in sequence along the length direction of the inverted frame 3, and any two adjacent tower sections 4 can be detachably connected; the tower section 4 is a structure with a hollow interior and openings at both ends along its length direction; the waist ring 16 is sleeved on the outside of the inverted frame 3, and the inverted frame 3 is formed with an installation cavity that penetrates the end away from the crawler body 1 along its length direction, the tower section 4 is arranged in the installation cavity, and the tower section 4 is connected to the waist ring 16; the lifting drive device 17 is arranged on the inverted frame 3 and is detachably connected to the tower section 4, and when the mobile self-folding and self-lifting holding rod is in the unfolded state, the lifting drive device 17 is used to drive the waist ring 16 to drive the tower section 4 to rise and fall synchronously;

[0058] When the mobile self-folding and self-lifting boom is in the unfolded state, along the vertical direction, the slewing mechanism 5 is arranged at the top of the tower section 4 at the highest point, the mast section 7 and the main arm 8 are arranged at the top of the slewing mechanism 5, and the slewing mechanism 5 is rotationally connected to the tower section 4 at the highest point, and the flipping drive mechanism 6 is used to drive the slewing mechanism 5 together with the mast section 7 and the main arm 8 to flip to the side of the tower section 4 and the flip frame 3 or unfold to the top of the tower section 4 at the highest point; the main arm 8 is rotationally connected to the slewing mechanism 5, and the unfolding drive mechanism 9 is used to drive the main arm 8 to unfold or retract relative to the slewing mechanism 5.

[0059] In this embodiment, the vehicle-mounted self-folding double-arm boom provided in the present application has two states: unfolded and folded:

[0060] When the arm needs to be stored after being deployed, the deployment drive mechanism 9 is first used to drive the main arm 8 to fold and store back to the side of the mast section 7. Since a plurality of tower sections 4 are stacked in sequence from top to bottom along the height direction of the flip frame 3, especially the bottom of the interior, until some of the upper parts exceed the flip frame 3, and then the tower section 4 is gradually moved out of the flip frame 3 from the bottom of the flip frame 3. In this process, the pins connecting two adjacent tower sections 4 can be manually disassembled, so as to facilitate the removal of the most important part from the opening of the flip frame 3. At the same time, the lifting drive device 17 is used to assist the top tower section 4 to descend one by one, and finally the slewing mechanism 5 falls to the top of the inverted frame 3, and then the turning drive mechanism 6 is used to drive the mast section 7 and the main arm 8 to turn to the side of the tower section 4 and the inverted frame 3, and finally the folding drive mechanism 2 is used to turn the folded whole structure onto the crawler body 1, so as to complete the folding and storage of the vehicle-mounted self-folding double-horizontal arm boom, and the boom can be transported away by the crawler body 1;

[0061] When the boom needs to be unfolded for use, the crawler vehicle body 1 can be used to move the boom to the designated position first, and then the folding drive mechanism 2 is used to flip down the folded flip frame 3, tower section 4, slewing mechanism 5, flipping drive mechanism 6, mast section 7, main arm 8 and the overall structure of the unfolding drive mechanism 9 from the crawler vehicle body 1, that is, flip from the original horizontal state to the vertical state, and then the tower section 4 is installed inside the flip frame 3 until the flip frame 3 is fully stacked along the height of the flip frame 3, and the adjacent tower body is stacked. The sections 4 are connected together by pins, etc., and then the lifting drive device 17 is used to assist the tower sections 4 above the top to rise and fall one by one, and as the tower sections 4 rise, new tower sections 4 need to be continuously added to the inversion frame 3 to avoid being suspended, until the preset working height position is reached, and then the turning drive mechanism 6 is used to drive the slewing mechanism 5 and the folding structure of the mast section 7, the main arm 8 and the unfolding drive mechanism 9 to be flipped from the side of the tower section 4 and the inversion frame 3 to the top of the tower section 4, and finally the unfolding drive mechanism 9 is used to drive the main arm 8 to unfold.

[0062] It can be seen that the present application provides a new type of boom, which can be folded and stored after use, occupies little space, and is equipped with a crawler body 1, which is more convenient for transportation and can be unfolded when used again.
