[0045] Refer to the following Figures 1 to 17 A vehicle-mounted self-folding lifting pole according to some embodiments of the present application is described.

[0046] See also Figures 1 to 17 As shown, an embodiment of the present application provides a vehicle-mounted self-folding lifting boom, comprising: a vehicle-mounted component 1, a folding drive mechanism 2, a flip frame 3, a heightening assembly, a lifting drive device 17, a rotating mechanism 5, a flip drive mechanism 6, a mast section 7, a main arm 8 and an unfolding drive mechanism 9; wherein the flip frame 3 is connected to the vehicle-mounted component 1 through the folding drive mechanism 2, and the folding drive mechanism 2 is used to drive the flip frame 3 from a horizontal state on the vehicle-mounted component 1 to an upright state located on the side of the vehicle-mounted component 1.

[0047] The heightening component includes a tower section 4 and a waist ring 16. There are multiple heightening components, which are arranged in sequence along the length direction of the flip 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 flip frame 3, and the flip frame 3 is formed with an installation cavity that penetrates through the end away from the vehicle-mounted component 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 flip frame 3 and is detachably connected to the tower section 4, and when the vehicle-mounted walking self-folding lifting boom 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.

[0048] When the vehicle-mounted self-folding 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.

[0049] In this embodiment, the vehicle-mounted self-folding lifting pole provided in the present application has two states: unfolded and folded:

[0050] 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 from 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 lowermost tower from the opening of the flip frame 3. Section 4, at the same time, the lifting drive device 17 is used to assist the top tower section 4 to descend one section at a time, and finally the slewing mechanism 5 falls to the top of the inverted frame 3, and then the flipping drive mechanism 6 is used to drive the mast section 7 and the main arm 8 to flip to the side of the tower section 4 and the inverted frame 3, and finally the folding drive mechanism 2 is used to flip the above-mentioned folded overall structure onto the vehicle-mounted component 1, thereby completing the folding and storage of the vehicle-mounted walking self-folding lifting boom, and the folded overall structure is convenient to be placed on a transport vehicle for easy transportation.

[0051] When the arm needs to be unfolded for use, the arm can first be moved to a designated position by a transport vehicle, 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 vehicle-mounted component 1, that is, flipped from the original horizontal state to a 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 sections 4 are stacked. They 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.

[0052] It can be seen that the present application provides a vehicle-mounted self-folding lifting boom, which can be folded and stored after use, occupies a small space, is more convenient for transportation, and can be unfolded when used again. The operation is simple and convenient, saving time and effort, greatly improving the efficiency of transmission line construction and saving manpower investment, which is of great significance in transmission line construction.

[0085] In this embodiment, the first supporting protrusion 102 and the second supporting protrusion 103 can support the flip frame 3 along the length direction of the flip frame 3 to improve the stability of the support, and lift the flip frame 3 a certain distance to provide an escape space for the connecting component 23 under the folded horizontal flip frame 3 to avoid interference, etc.

[0086] Further, preferably, the first supporting protrusion 102 and the second supporting protrusion 103 and the body 101 can be an integrated structure, with high overall strength, good supporting effect, not easy to be damaged, and long service life. Of course, not limited to this, the first supporting protrusion 102 and the second supporting protrusion 103 and the body 101 can be a split structure, and later connected by welding or other methods.

[0087] In one embodiment of the present application, preferably, Figure 2 As shown, the second supporting protrusion 103 is formed with positioning grooves 1031 penetrating the top and two opposite sides thereof, and the flip-chip frame 3 is installed in the positioning grooves 1031 .

[0088] In this embodiment, part of the structure of the horizontal flip frame 3 can be installed in the positioning groove, thereby limiting the position of the flip frame 3, making the folded holding pole more stable during transportation and preventing it from falling. Of course, the positioning groove 1031 may not be provided on the second supporting protrusion 103, depending on actual needs.

[0089] It should be noted that the slewing mechanism 5 is a slewing drive device in the prior art, which can drive the mast section 7 and the main arm 8 to freely rotate within a range of 360° in the horizontal plane. It is quite common and will not be described in detail here.

[0090] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
