DETAILED DESCRIPTION

[0015] The present invention is described in detail below in conjunction with the accompanying drawings: The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0016] Please refer to Figure 1 , which illustrates a diagonal grid structure 200 and a connection node between the inclined steel columns 210 and the special-shaped cross steel pipe members 220 thereon.

[0017] Please refer to Figures 2 to 3 The embodiment of the present invention provides a hoisting system 100 for a special-shaped cross steel pipe member, comprising a hook 110, a hoisting rope 120, an automatic telescopic rod 130, an electric wire reel 140 and a laser alignment instrument 150, wherein: The hook 110 is connected to the lifting device, wherein the hook 110 can be a component on the lifting device, or can be other indirect lifting tools.

[0018] There are two suspension ropes 120, and the two suspension ropes 120 are symmetrically connected to the hook 110. In order to improve the strength of the suspension rope 120, the suspension rope 120 can be a steel wire rope.

[0019] The automatic telescopic rod 130 is located below the hook 110. Figures 2 to 3 In order to realize the angle control of the suspension rope 120 on at least one side, the automatic telescopic rod 130 can be a unidirectional telescopic rod or a bidirectional telescopic rod.

[0020] There are two electric wire reels 140 , which are respectively disposed at two ends of the automatic telescopic rod 130 . The electric wire reels 140 at two ends of the automatic telescopic rod 130 respectively wind up the suspension rope 120 at the corresponding side.

[0021] The laser alignment device 150 is arranged on the vertical center line of the hook 110 and is used to emit a light 151. The light 151 can symmetrically distribute the two suspension ropes 120.

[0022] Please refer to Figures 2 to 3 The embodiment of the present invention further provides a method for installing a special-shaped cross steel pipe component, using the above-mentioned hoisting system 100 of the special-shaped cross steel pipe component, comprising: Step 301, mark the center of gravity position on the special-shaped cross steel pipe component 220 to be hoisted, where the center of gravity is represented by G. In order to quickly find the position of the center of gravity G on the special-shaped cross steel pipe component 220 to be hoisted, the BIM model can be used to find the center of gravity position of the special-shaped cross steel pipe component 220 in the drawing and mark it on the corresponding position of the special-shaped cross steel pipe component 220 at the hoisting site.

[0023] Step 302, connecting the outlet ends of the two hanging ropes 120 wound by the two electric reels 140 to the special-shaped cross steel pipe member 220. In order to smoothly hang the special-shaped cross steel pipe member 220, the two hanging ropes 120 can be symmetrically connected between the hook 110 and the special-shaped cross steel pipe member 220.

[0024] Step 303 , turning on the laser alignment instrument 150 , and controlling the hoisting system 100 through the hoisting equipment to hoist the special-shaped cross steel pipe member 220 to the top of the installed inclined steel column 210 .

[0025] Step 304, control the hoisting system 100 to move in the horizontal direction through the hoisting equipment, so as to align the special-shaped cross steel pipe member 220 with the inclined steel column 210 in the horizontal direction. Figure 4 and Figure 6 , wherein the horizontal alignment includes the X direction and the Y direction.

[0026] Step 305, during the hoisting and alignment process of the special-shaped cross steel tube component 220, the telescopic length of the automatic telescopic rod 130 is controlled to drive the rope 120 at at least one end thereof to change the opening angle, so that the center of gravity position of the special-shaped cross steel tube component 220 is changed by the rope 120 after the changing opening angle, so that the light 151 emitted by the laser alignment instrument 150 is aligned with the center of gravity G of the special-shaped cross steel tube component 220; the electric wire reel 140 located at at least one end of the automatic telescopic rod 130 is controlled to telescope the rope 120 on its side to change the length of the corresponding rope 120, so that the special-shaped cross steel tube component 220 is returned to the center, so that the light 151 emitted by the laser alignment instrument 150 coincides with the vertical symmetry axis 222 of the special-shaped cross steel tube component 220 (i.e., aligned); so that the special-shaped cross steel tube component 220 is balanced hoisted and aligned on the inclined steel column 210.

[0027] The detailed principle of aligning the center of gravity of the special-shaped cross steel tube component 220 is as follows: the automatic telescopic rod 130 is adjusted to adjust its telescopic length to change the opening angle of at least one of the suspension ropes 120, thereby changing the vertical projection length of the suspension rope 120 relative to the horizontal plane, so that the special-shaped cross steel tube component 220 has an inclination angle to change its center of gravity position, so that the light 151 emitted by the laser alignment instrument 150 is aligned on the center of gravity of the special-shaped cross steel tube component 220.

[0028] The detailed principle of the coincidence of the light emitted by the laser alignment instrument with the vertical symmetry axis of the special-shaped cross steel tube component 220 is as follows: the electric wire reel 140 located at at least one end of the automatic telescopic rod 130 controls the extension and retraction of the suspension rope 120 on its side to change the length of the corresponding suspension rope 120, and then the special-shaped cross steel tube component 220 rotates around the center of gravity G, changing the inclination angle of the special-shaped cross steel tube component 220 to make it in a return state, wherein the vertical symmetry axis 222 of the special-shaped cross steel tube component 220 is in the vertical direction and is in the return state.

[0029] Step 306: Control the hoisting system 100 to move in the height direction (mainly downward at this time) by means of the hoisting equipment, so as to install the special-shaped cross steel pipe member 220 on the inclined steel column 210. Figure 2 and Figure 3 An X-shaped special-shaped cross steel pipe member 220 is exemplified.
