The electric control box fixed bracket can be a flat bracket 2 for the electric control box or a side bracket 3 for the electric control box.

[0036] like Figures 1 to 3As shown, the lifting mobile bracket 1 is a first frame structure surrounded by multiple rods. The top of the first frame structure is provided with a set of lifting holes and the bottom is provided with a set of connecting parts. Specifically, the first frame structure consists of a top rectangular frame, a bottom rectangular frame, and two columns 107. The top rectangular frame is welded to the bottom rectangular frame via the two columns 107, resulting in the first frame structure being welded from several small rectangular steel bars. It has excellent bending and torsion resistance. Compared with solid beams of the same cross-section, it has the advantages of light weight, low material consumption, good bending resistance, and a compact structure with good load-bearing capacity. In addition, multiple lifting points are designed at the top of the first frame structure, which is versatile and interchangeable. Among them, the top rectangular frame is composed of two first cross beams 106 and two first longitudinal beams 108 connected end to end. A lifting plate 103 with seven lifting holes is provided on the first cross beam 106, and a lifting lug 102 with one lifting hole is provided on the first longitudinal beam 108. The bottom rectangular frame consists of two second transverse beams 109 and two second longitudinal beams 105 connected end to end. A second longitudinal beam 105 is connected midway between the two second transverse beams 109. A first connecting plate 104 with an L-shaped cross section is installed on the outside of one second transverse beam 109, and two first connecting plates 104 with L-shaped cross sections are installed on the outside of the other second transverse beam 109. These first connecting plates 104 are fixed to the electrical control box bracket with screws. Furthermore, reinforcing ribs 101 are installed between the upper end of the column 107 and the first transverse beam 106, and between the lower end of the column 107 and the second transverse beam 109. The stiffener plate 101, lifting lugs 102, lifting plate 103, and first connecting plate 104 are all made of high-strength D36 steel. The second longitudinal beam 105, first transverse beam 106, columns 107, first longitudinal beam 108, and second transverse beam 109 are all welded from Q345B rectangular tubes, measuring 120*60*5" or 150*100*5". Rectangular tubes are hollow, long strips of steel, also known as flat tubes. While maintaining the same bending and torsional strength, they are lightweight and easy to lift and transport.

The fixing members are used to install the electric control box 4, and the connecting members are used to connect the first frame structure and the second frame structure.

[0038] When the electric control box fixing bracket is the electric control box lying bracket 2, its structure is as follows: Figure 4 and Figure 5As shown, it is welded from several small rectangular steel bars and exhibits excellent bending and torsional resistance. Compared to solid beams of the same cross-section, it offers advantages such as light weight, reduced material consumption, and excellent bending resistance. It also features a compact structure and good load-bearing capacity. The horizontal support 2 for the control box is a rectangular frame structure formed by two third crossbeams 201 and two third longitudinal beams 202 connected end to end. A third longitudinal beam 202 is also connected in the middle of the two third crossbeams 201. Two second connecting plates 204 with L-shaped cross-sections are respectively provided on the two outer third longitudinal beams 202. These second connecting plates 204 are directly fixed to the second crossbeam 109 via screws. Two third connecting plates 205 with L-shaped cross-sections are respectively provided on the inner sides of the two third crossbeams 201. These third connecting plates 205 are fixed to the movable support via screws. Furthermore, the four corners of the rectangular frame structure are provided with first fixing members 203, similar to T-shaped brackets. These first fixing members 203 are angle steels and are fixed to the control box 4 via screws. The first fixing member 203, the second connecting plate 204 and the third connecting plate 205 are all made of high-strength steel D36, and the third cross beam 201 and the third longitudinal beam 202 are both welded from rectangular tubes made of Q345B, with dimensions of 70*40*4 or 70*70*5.

[0039] When the electric control box fixing bracket is a side-lying bracket, its structure is as follows: Figure 6 and Figure 7 As shown, it is welded from several small rectangular steel bars and has excellent bending and torsional properties. Compared with solid beams of the same cross-section, it has the advantages of light weight, low material consumption, good bending resistance, and a compact structure with good load-bearing capacity. The side-lying bracket 3 of the electric control box is a rectangular frame structure formed by two fourth cross beams 301 and two fourth longitudinal beams 302 connected end to end. A fourth longitudinal beam 302 is also connected in the middle of the two fourth cross beams 301. Two fourth connecting plates 304 with L-shaped cross sections are respectively provided at the lower ends of the two outer fourth longitudinal beams 302. The distance between the two fourth connecting plates 304 is the height of the second cross beam 109. The fourth connecting plates 304 are fixedly connected to the second cross beam 109 of the lifting and moving bracket 1 by screws. In addition, second fixing members 303 are provided at the four corners of the rectangular frame structure. The second fixing members 303 are angle steels and can be fixedly connected to the electric control box 4 by screws. The second fixing member 303 and the fourth connecting plate 304 are both made of high-strength steel D36, and the fourth crossbeam 301 and the two fourth longitudinal beams 302 are both welded from rectangular tubes made of Q345B, with dimensions of 70*40*4 or 70*70*5.

[0040] The operation method of installing the auxiliary bracket of the electric control box in this embodiment is as follows:

[0041] 1) When placing the tower of an electric crane horizontally, place it on sleepers or special iron piers (with the cab facing upwards). It must be placed steadily and coordinated with the crane operator and the crane operator.

[0042] 2) Select different fixing auxiliary brackets (i.e., electric control box horizontal bracket 2 or electric control box side bracket 3) according to the different installation positions of the electric control box 4 in the tower body, and fix the fixing auxiliary bracket to the lifting movable bracket 1. Figure 8 and Figure 9 ;

[0043] 3) Use the workshop's crane or other auxiliary lifting tools to lift the electric control box 4, and send the electric control box 4 from the cab frame on the tower body into the tower body. According to the installation position of the electric control box 4, the assembler cooperates with the command of the crane or other auxiliary lifting tools to move the entire electric control box installation auxiliary bracket forward, backward, left and right. After it reaches the appropriate position, it is lowered and installed. After completion, the entire electric control box installation auxiliary bracket is removed.

[0044] It is important to confirm with the designer the center of gravity of the electric control box 4 and the entire electric control box installation auxiliary bracket before lifting the electric control box 4 and determine the lifting point.
