[0026] The public support 1 includes a frame body 2 and a plurality of hanging rings 3 arranged around the frame body 2 .

[0027] See also Figures 1 to 5 , the large-diameter pipeline common support hoisting device provided by the utility model is now described. The large-diameter pipeline common support hoisting device includes a plurality of I-beams 10 and a plurality of groups of electric hoists 20. The plurality of I-beams 10 are arranged on the inner top wall of the concrete frame 4 at intervals along the horizontal direction; the plurality of groups of electric hoists 20 are arranged one by one at the bottom of the plurality of I-beams 10, and each group of electric hoists 20 includes at least two electric hoists 20 arranged at intervals along the extension direction of the I-beams 10. The electric hoists 20 have a sling 21 for connecting with the lifting ring 3, and each sling 21 is connected to the plurality of lifting rings 3 in a one-to-one correspondence. The two sides of the electric hoists 20 respectively have positioning rods 30 extending horizontally outward, and the outer peripheries of the two positioning rods 30 are respectively provided with hooks 40 through sliding sleeves 90. The two hooks 40 are arranged oppositely and are respectively hooked on the two side edges of the lower wing plate 11 of the I-beam 10 in a one-to-one correspondence, and the sliding sleeve 90 is locked by a locking member 50.

[0028] The embodiment of the present application provides a large-diameter pipeline common support lifting device. During its actual use, a plurality of I-beams 10 are arranged in parallel and spaced apart in pairs and fixed on the inner top wall of the concrete frame 4. When the position of the electric hoist 20 needs to be adjusted, it is only necessary to release the lock of the sliding sleeve 90 by the locking member 50, so that the two hooks 40 can slide along the axial direction of the positioning rod 30 toward the outer end of the positioning rod 30, thereby releasing the squeezing force of the two hooks 40 on the I-beam 10, making it convenient for the electric hoist 20 to slide and adjust the position along the extension direction of the I-beam 10, saving time and effort and improving work efficiency.

[0029] Compared with the prior art, the large-diameter pipeline common support lifting device provided in the present embodiment is simple in that when the position of the electric hoist 20 needs to be adjusted, it is only necessary to release the lock of the locking piece 50 on the position of the sliding sleeve 90, so that the two hooks 40 can slide along the axial direction of the positioning rod 30 toward the outer end of the positioning rod 30, thereby releasing the squeezing force of the two hooks 40 on the I-beam 10, making it convenient for the electric hoist 20 to slide and adjust its position along the extension direction of the I-beam 10, saving time and effort and improving work efficiency.

[0030] In a possible implementation, the electric hoist 20 is as follows: Figures 2 to 4 The structure shown, see Figures 2 to 4 The top of the electric hoist 20 is provided with two U-shaped buckles 60 with openings set downward, and a plug-in cavity 61 is formed between the U-shaped buckle 60 and the electric hoist 20 and passes through the extension direction of the I-beam 10. The top of the electric hoist 20 is provided with a plug-in block 70 that passes through the two plug-in cavities 61, and the two positioning rods 30 are detachably connected to the two sides of the plug-in block 70 one by one.

[0031] Specifically, the plug-in block 70 is fixed in the plug-in cavity 61 by locking the U-shaped buckle 60. The setting of the plug-in block 70 facilitates the installation of the positioning rod 30, and indirectly connects the hook 40 with the electric hoist 20, making it convenient for the hook 40 to hang the electric hoist 20 at the bottom of the I-beam 10.

[0032] In some embodiments, see Figure 2 and Figure 3 Slots 71 are respectively provided on the two side walls of the plug-in block 70, and the positioning rod 30 is inserted into the slots 71. A pin shaft 80 is provided on the top of the plug-in block 70 and penetrates downwardly through the plug-in block 70 and the positioning rod 30 respectively.

[0033] Specifically, a socket connected to the slot 71 is penetrated through the plug-in block 70 in the up-down direction, and a positioning hole is penetrated through the inner end of the positioning rod 30 in the up-down direction. When the positioning hole and the socket are aligned, the pin 80 can be inserted into the positioning hole and the socket, thereby locking the position of the positioning rod 30 in the slot 71, facilitating the installation and disassembly of the positioning rod 30 and the plug-in block 70.

[0034] In some embodiments, see Figure 2 and Figure 4 The two lower ends of the U-shaped buckle 60 respectively have connecting plates 62 for fitting onto the top surface of the electric hoist 20 , and the connecting plates 62 are connected to the electric hoist 20 via bolts 63 .

[0035] Specifically, the connecting plate 62 on the U-shaped buckle 60 is directly tightened to the electric hoist 20 by bolts 63, and two connecting plates 62 are symmetrically arranged on the U-shaped buckle 60, and a bolt 63 is fixed on each connecting plate 62, thereby improving the connection stability between the U-shaped buckle 60 and the electric hoist 20.

[0036] In a possible implementation, the locking member 50 is configured as follows: Figure 2 The structure shown, see Figure 2 The locking member 50 is a locking nut threadedly sleeved on the outer periphery of the positioning rod 30 . The locking nut is located on the outer side of the sliding sleeve 90 . The locking nut can be rotated toward the direction close to the I-beam 10 to push the sliding sleeve 90 .

[0037] Specifically, when it is necessary to lock the position of the hook 40, it is only necessary to rotate the locking nut to push the sleeve 90 so that the hook 40 abuts against the side edge of the lower wing plate 11 of the I-beam 10. Even if the two hooks 40 move toward each other to clamp the two side edges of the lower wing plate 11, the position of the hook 40 on the I-beam 10 can be locked, which facilitates the fixation of the position of the hook 40.

[0038] When the position of the electric hoist 20 needs to be adjusted, the locking nut can be loosened, which facilitates the adjustment of the position of the hook 40, that is, the adjustment of the position of the electric hoist 20.

[0039] In some embodiments, see Figure 2 The outer end surface of the locking nut is connected to a U-shaped handle 51 with an opening facing the locking nut, and the outer end of the positioning rod 30 is located in the U-shaped handle 51.

[0040] Specifically, the opening of the U-shaped handle 51 is used to avoid the positioning rod 30 to avoid interference with the positioning rod 30 when rotating the adjustment locking nut. At the same time, the setting of the U-shaped handle 51 also makes it convenient for the staff to directly apply force to the locking nut with their hands, avoiding the tedious process of relying on external auxiliary tools.

[0041] In a possible implementation, the positioning rod 30 is as follows: Figure 2 and Figure 5 The structure shown, see Figure 2 and Figure 5 A positioning groove 31 extending axially to the outer end is provided on the peripheral wall of the positioning rod 30, and a positioning block 91 extending into the positioning groove 31 is provided on the inner wall of the sliding sleeve 90. The positioning block 91 and the positioning groove 31 are slidably matched in the axial direction of the positioning rod 30.

[0042] Specifically, through the sliding cooperation between the positioning block 91 and the positioning groove 31 , the sliding sleeve 90 can stably slide along the axial direction of the positioning rod 30 , thereby avoiding the relative rotation between the sliding sleeve 90 and the positioning rod 30 .

[0043] In a possible implementation, the hook 40 is used as follows Figure 1 and Figure 2 The structure shown, see Figure 1 and Figure 2The hook 40 includes a vertical portion 42 extending upward and a bent portion 41 connected to the upper edge of the vertical portion 42 and extending horizontally inward to hook on the lower wing plate 11 , and the lower edge of the vertical portion 42 is connected to the sliding sleeve 90 .

[0044] Specifically, the vertical portion 42 can leave a sufficient gap between the lower wing plate 11 and the electric hoist 20 to facilitate the installation of other components, and the bent portion 41 can allow the hook 40 to be stably hooked on the lower wing plate 11.

[0045] In some embodiments, see Figure 2 A ball 411 for rolling cooperation with the lower wing plate 11 is embedded on the bottom surface of the bent portion 41 .

[0046] Specifically, after releasing the locking piece 50 , the electric hoist 20 can be dragged to move along the length direction of the I-beam 10 , and the ball 411 rolls with the top surface of the lower wing plate 11 , reducing the friction between the bending portion 41 and the lower wing plate 11 , making it easier to adjust the position of the electric hoist 20 .

[0047] In a possible implementation, the I-beam 10 is Figure 1 and Figure 2 The structure shown, see Figure 1 and Figure 2 The upper wing plate 12 of the I-beam 10 is connected to the concrete frame 4 through a connecting piece 13.

[0048] Specifically, a plurality of connecting members 13 are provided along the extending direction of the I-beam 10 . The connecting members 13 are expansion bolts 63 , which can enhance the connection stability between the upper wing plate 12 and the concrete frame 4 .

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
