DETAILED DESCRIPTION

[0023] The specific embodiments of the utility model are described in detail below in combination with the drawings:

[0024] As Figs. 1-4 shown, a kind of transport tool of the electrical cabinet in the offshore wind power tower drum, install in the wind power tower drum 1 bottom that is built-in electrical cabinet 2, for carrying wind power tower drum 1, and while supporting electrical cabinet 2. Transport tool includes the tool base frame 3 of being set in the bottom of wind power tower drum 1 and the multiple groups of auxiliary support 4 for supporting electrical cabinet 2.

[0025] Tool base frame 3 is the steel structure frame of section steel assembly, when fixed, wind power tower drum 1 is placed on tool base frame 3, and the flange of tower drum on wind power tower drum 1 and tool base frame 3 spot welding are fixed, so that tool base frame 3 and wind power tower drum 1 can be connected and fixed.

[0026] To ensure that tool base frame 3 carries wind power tower drum 1 in multiple directions, tool base frame 3 includes rectangular frame 31 and trapezoidal frame 32, and the length of rectangular frame 31 is greater than the diameter of wind power tower drum 1, and then the both ends of rectangular frame 31 extend outside wind power tower drum 1. Trapezoidal frame 32 is symmetrically arranged on both sides of the middle part of rectangular frame 31, and the trapezoidal frame 32 on both sides and the middle part of rectangular frame 31 are combined to form a near circle, so that it can be well adapted to the cross section of wind power tower drum 1, ensure that wind power tower drum 1 is supported in all directions, increase the reliability of the connection between wind power tower drum 1 and tool base frame 3.

[0027] In order to support the electrical cabinet 2 inside the wind power tower 1, a plurality of auxiliary support pieces 4 are arranged above the tooling base frame 3, which can support a plurality of electrical cabinets 2. The auxiliary support pieces 4 are vertically arranged, and each group of auxiliary support pieces 4 corresponds to one electrical cabinet 2, and the top of the auxiliary support piece 4 extends upward and abuts against the bottom surface of the electrical cabinet 2. Thus, the electrical cabinet 2 can be supported to ensure the stability of the electrical cabinet 2 and prevent the original connecting structure from being difficult to deform.

[0028] In order to facilitate the operation of the auxiliary support piece 4 to support the electrical cabinet 2, the auxiliary support piece 4 needs to have a height adjustment function. Therefore, each group of auxiliary support pieces 4 includes a plurality of height adjustment rods 5, and the height adjustment rod 5 itself is adjustable in height. A plurality of height adjustment rods 5 are used to jointly support one electrical cabinet 2, which can improve the stability of the electrical cabinet 2.

[0029] In the embodiment, each height adjustment rod 5 includes a fixed base 6 and an adjustable top rod 7 arranged above the fixed base 6. Thus, the length of the height adjustment rod 5 can be extended or shortened to meet the application requirements.

[0030] The fixed base 6 includes an upper support plate 61, a lower support plate 62, and a lead screw sleeve 63. The upper support plate 61 and the lower support plate 62 are arranged in an upper-lower interval, and the lead screw sleeve 63 is arranged between the upper support plate 61 and the lower support plate 62. In order to improve the structural strength of the fixed base 6, the cross section of the upper support plate 61 is smaller than that of the lower support plate 62. Four groups of reinforcing pieces are arranged between the upper support plate 61 and the lower support plate 62, and the four groups of reinforcing pieces are evenly distributed around the side of the lead screw sleeve 63. Each group of reinforcing pieces includes two reinforcing plates 8 arranged at intervals, and the cross section of the reinforcing plate 8 is a right trapezoid. Thus, the connection strength of the upper support plate 61 and the lower support plate 62 is improved based on the lead screw sleeve 63 through the reinforcing plate 8, thereby increasing the structural strength of the entire fixed base 6.

[0031] The adjustable top rod 7 is a lead screw structure, and the adjustable top rod 7 is rotatably engaged in the lead screw sleeve 63. By screwing the adjustable top rod 7, the height of the height adjustment rod 5 can be increased or decreased, and the height can be adjusted steplessly. In addition, the adjustable top rod 7 can be prevented from being unexpectedly rotated back.

[0032] In order to facilitate the screwing of the adjustable top rod 7, a rotating handle 9 is connected to the lead screw sleeve 63 after the adjustable top rod 7 extends out of the lead screw sleeve 63. Workers can conveniently control the adjustable top rod 7 through the rotating handle 9, thereby avoiding the need to invest more personnel to operate. In addition, a top support column 10 is arranged at the upper end of the adjustable top rod 7. The top support column 10 is a T-shaped column, which can increase the contact area with the bottom surface of the electrical cabinet 2 and ensure the stability of the support position.

[0033] The utility model discloses a principle is: the tooling underframe 3 is hung and is placed to the transport ship and is fixed, and the auxiliary support piece 4 is arranged in advance according to the position of electrical cabinet 2 on the tooling underframe 3, guarantees that one electrical cabinet 2 can be supported by multiple height adjusting rods 5. Again, the wind power tower drum 1 with electrical cabinet 2 built-in is hung and is placed to the tooling underframe 3, and the height adjusting rod 5 is manually operated manually, so that adjustable top rod 7 moves up, contacts electrical cabinet 2 and stops. Finally, the wind power tower drum 1 and the tooling underframe 3 are spot-welded together by using tower drum flange.

[0034] Therefore, the deformation of the original connecting structure of the electrical cabinet 2 can be avoided, and the knocking phenomenon of the electrical cabinet 2 in the transportation process can be prevented. Meanwhile, the position of the auxiliary support piece 4 is adjustable, and the stable bearing requirements of the electrical cabinet 2 at various positions in the wind power tower drum 1 can be met.

[0035] The above-mentioned embodiments are only preferred embodiments of the utility model, and do not limit the implementation range of the utility model, so equivalent changes or modifications made according to the structure, features and principles described in the patent range of the utility model should be included in the patent range of the utility model application.
