Detailed Description

The present invention will be described in further detail with reference to the drawings and the following detailed description.

Referring to fig. 1 to 4, the present embodiment provides an assembled tower crane, which includes a mast 100, a frame 200, a fixing device 400, and a console 500.

The mast 100 has a rectangular parallelepiped structure as a whole. A plurality of bar members may be assembled and arranged in a truss structure. The mast 100 is elongated in the vertical direction (z). The mast 100 may be secured to the external support 10 by a frame 200 and a support 300.

The frame 200 is used to secure the mast 100 to the external support 10. The frame 200 fixes the mast 100 and is connected to the support 300. The frame 200 may be disposed outside the mast 100. The frame 200 may have a quadrilateral shape in the x-y plane when viewed from above.

The mast 100 is disposed in a vertical direction z and the frame 200 may be disposed in an x-y plane.

The fixture 400 connects the frame 200 and the mast 100. One side of the fixing device 400 may be disposed on the frame 200, and the other side of the fixing device 400 may be coupled to the mast 100.

The console 500 is fixed to the outer bracket 10 to fix the bracket 300 and the outer bracket 10.

The frame 200 may include a plurality of

unit frames

200A, 200B, 200C, and 200D. For example, four

unit frames

200A, 200B, 200C, and 200D may be combined to form one frame 200. Each of the

unit frames

200A, 200B, 200C, and 200D may include a horizontal frame 210 and a vertical frame 220. The vertical frame 220 may be connected to one end of the horizontal frame 210. These

unit frames

200A, 200B, 200C, and 200D may have an overall "L" shape. The plurality of

unit frames

200A, 200B, 200C, and 200D may be identical in size and shape.

The end portions of each of the

unit frames

200A, 200B, 200C, and 200D may be coupled to each other by separate fastening members.

The fixing device 400 may be disposed near the corners of the

unit frames

200A, 200B, 200C, and 200D. As an example, one fixture 400 may be provided on the horizontal frame 210 and the other may be provided on the vertical frame 220. The fixture 400 is connected to the mast 100. When the frame 200 is viewed as a whole, the fixing device 400 may be disposed near an edge of the frame 200.

The shims 600 may be provided when the frame 200 is coupled to masts 100 having different sizes. The spacer 600 is disposed between an end of one side of the

unit frames

200A, 200B, 200C, and 200D and an end of the other side of the

unit frames

200A, 200B, 200C, and 200D. And the ends of the

unit frames

200A, 200B, 200C, and 200D at one side and the ends of the

unit frames

200A, 200B, 200C, and 200D at the other side are coupled to each other by the spacers 600 interposed therebetween.

Various sizes of shims 600 can be selected and applied to correspond to the dimensions of the mast 100. Therefore, when the spacers 600 of various sizes are applied, there is an advantage in that the masts 100 of various sizes can be fixed with the

unit frames

200A, 200B, 200C and 200D of specific sizes. The frame 200 has the advantage of very high compatibility, considering that each manufacturer or model of mast 100 has a different size and shape.

As the dimensions of the mast 100 change, the position of the fixture 400 needs to change because the relative position of the mast 100 with respect to the frame 200 is different. Therefore, the tower crane apparatus according to the present embodiment is configured to be able to change the position of the fixing device 400 according to the size of the mast 100.

It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalent technologies, the present invention is also intended to include such modifications and variations.
