[0042] The present invention will be described in detail below with reference to the accompanying drawings: According to the following description, the advantages and features of the present invention will be clearer. It should be noted that the accompanying drawings are all in a very simplified form and use non-precise scales, only for conveniently and clearly assisting in explaining the purpose of the embodiments of the present invention.

[0043] Please refer to Figure 1 , which exemplifies the connection node of the oblique grid structure 200 and the inclined steel column 210 and the special-shaped cross steel pipe member 220 thereon.

[0044] 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, including a hook 110, a hoisting rope 120, an automatic telescopic rod 130, an electric wire winder 140 and a laser aligner 150, wherein:

[0045] The hook 110 is connected to the hoisting equipment. The hook 110 can be a component of the hoisting equipment or other indirect lifting tools.

[0046] There are two lifting ropes 120, and the two lifting ropes 120 are symmetrically connected to the hook 110. To improve the strength of the lifting ropes 120, the lifting ropes 120 can be steel ropes.

[0047] The automatic telescopic rod 130 is located below the hook 110. Please refer to Figures 2 to 3 , in order to realize the control of the opening angle of at least one side of the lifting rope 120, the automatic telescopic rod 130 can be a unidirectional telescopic rod or a bidirectional telescopic rod.

[0048] There are two electric wire reels 140, which are respectively arranged at both ends of the automatic telescopic rod 130. The electric wire reels 140 at both ends of the automatic telescopic rod 130 respectively wind the lifting ropes 120 on their respective sides.

[0049] The laser aligner 150 is arranged on the vertical center line of the hook 110 and is used to emit a light ray 151. The light ray 151 can make the two lifting ropes 120 symmetrically distributed.

[0050] Please refer to Figures 2 to 3 , the embodiment of the present invention also provides an installation method for a special-shaped cross steel pipe member, adopting the above-mentioned hoisting system 100 for the special-shaped cross steel pipe member, including:

[0051] Step 301: Mark the centroid position on the special-shaped cross steel pipe member 220 to be hoisted, where the centroid is represented by G. In order to quickly find the position of the centroid G on the special-shaped cross steel pipe member 220 to be hoisted, the centroid position of the special-shaped cross steel pipe member 220 in the drawing can be found by using the BIM model and marked at the corresponding position of the special-shaped cross steel pipe member 220 at the hoisting site.

[0052] Step 302: Connect the outlet ends of the two lifting ropes 120 wound by the two electric wire reels 140 to the special-shaped cross steel pipe member 220. In order to hoist the special-shaped cross steel pipe member 220 smoothly, the two lifting ropes 120 can be symmetrically connected between the hook 110 and the special-shaped cross steel pipe member 220.

[0053] Step 303: Turn on the laser aligner 150, and control the hoisting system 100 through the hoisting equipment to hoist the special-shaped cross steel pipe member 220 above the already installed inclined steel column 210.

[0054] Step 304, control the hoisting system 100 to move horizontally through the hoisting equipment, so as to align the special-shaped cross steel pipe member 220 with the inclined steel column 210 horizontally. Please refer to Figure 4 and Figure 6 , where the horizontal alignment includes the X direction and the Y direction.

[0055] Step 305, during the hoisting and alignment of the special-shaped cross steel pipe member 220, control the telescopic length of the automatic telescopic rod 130 to drive the sling 120 at at least one end thereof to change the included angle, so as to change the center of gravity position of the special-shaped cross steel pipe member 220 by the sling 120 after changing the included angle, and realize that the light ray 151 emitted by the laser aligner 150 is aligned with the center of gravity G of the special-shaped cross steel pipe member 220; control the telescopic length of the sling 120 on the corresponding side by the electric winch 140 at at least one end of the automatic telescopic rod 130 to change the length of the corresponding sling 120, so as to straighten the special-shaped cross steel pipe member 220, and realize that the light ray 151 emitted by the laser aligner 150 coincides (i.e., is aligned) with the vertical symmetry axis 222 of the special-shaped cross steel pipe member 220; so that the special-shaped cross steel pipe member 220 is hoisted and aligned on the inclined steel column 210 in a balanced manner.

[0056] The detailed principle of aligning the center of gravity of the special-shaped cross steel pipe member 220 is as follows: adjust the telescopic length of the automatic telescopic rod 130 to change the included angle of at least one sling 120, thereby changing the vertical projection length of the sling 120 relative to the horizontal plane, so as to make the special-shaped cross steel pipe member 220 generate an inclination angle to change its center of gravity position, and realize that the light ray 151 emitted by the laser aligner 150 is aligned with the center of gravity of the special-shaped cross steel pipe member 220.

[0057] The detailed principle of the coincidence of the light ray emitted by the laser aligner and the vertical symmetry axis of the special-shaped cross steel pipe member 220 is as follows: control the telescopic length of the sling 120 on the corresponding side by the electric winch 140 at at least one end of the automatic telescopic rod 130 to change the length of the corresponding sling 120, then the special-shaped cross steel pipe member 220 rotates around the center of gravity G, changes the inclination angle of the special-shaped cross steel pipe member 220, and makes it in a straightened state, where the vertical symmetry axis 222 of the special-shaped cross steel pipe member 220 is in the vertical direction when it is in the straightened state.

[0058] Step 306, control the hoisting system 100 to move in the height direction (at this time, mainly move downward) through the hoisting equipment, so as to install the special-shaped cross steel pipe member 220 on the inclined steel column 210.
