[0033] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0034] like Figures 1-5 As shown, this embodiment of a steel structure steel pipe column installation and hoisting mechanism includes a buckle body 1, a pin shaft 2, a pin sleeve 3, and a release rope 4. The buckle body 1 has a U-shaped structure, and a first insertion hole and a second insertion hole are respectively opened on the side walls of both ends of the buckle body 1. The first insertion hole and the second insertion hole are arranged coaxially. The pin shaft 2 is movably sleeved in the first insertion hole and the second insertion hole. One end of the pin shaft 2 is provided with a retaining connector 22, and the other end of the pin shaft 2 is provided with a limiting channel 21. The limiting channel 21 is arranged perpendicular to the central axis of the pin shaft 2. The pin sleeve 3 is inserted into the limiting channel 21 and is retained in the other end of the pin shaft 2. One end of the release rope 4 is connected to the retaining connector 22 at one end of the pin shaft 2, and the other end of the release rope 4 passes through the pin sleeve 3 and is left free. The retaining connector 22 is provided with a through hole 23 for the release rope 4 to pass through.

[0035] The size of the card connector 22 is larger than the inner diameter of the first and second insertion holes.

[0036] like Figure 1 and Figure 5 As shown, the pin sleeve 3 in this embodiment includes a plug-in arm 31 and a snap-fit ​​arm arranged side by side. One end of the plug-in arm 31 is bent once to form a threaded loop 36 and then integrally connected to one end of the snap-fit ​​arm. The plug-in arm 31 is inserted into the limiting channel 21, and the snap-fit ​​arm is snapped into the other end of the pin 2. The pin sleeve, by providing the plug-in arm and the snap-fit ​​arm, facilitates insertion and snap-fit ​​with the limiting channel of the pin 2.

[0037] Specifically, such as Figure 1 and Figure 5As shown, the snap-fit ​​arm in this embodiment includes a first limiting segment 32, a protruding segment 33, and a second limiting segment 34 integrally connected in sequence. One end of the first limiting segment 32 is integrally connected to one end of the plug-in arm. The distance between the first limiting segment 32 and the plug-in arm, and the distance between the second limiting segment 34 and the plug-in arm 31, are both smaller than the distance between the protruding segment 33 and the plug-in arm 31. By providing the limiting segment and the protruding segment, the pin sleeve can be conveniently limited to the other end of the pin shaft.

[0038] Specifically, such as Figure 1 and Figure 5 As shown, in this embodiment, the inner wall of the limiting channel 21 near the other end face of the pin 2 is a snap-fit ​​position, where the insertion arm 31 is inserted and limited. The distance between the first limiting segment 32 and the insertion arm 31, and the distance between the second limiting segment 34 and the insertion arm 31, are smaller than the distance between the other end face of the pin 2 and the snap-fit ​​position. The two limiting segments and the protruding segment can be used to cooperate to limit the snap-fit ​​arm to the other end of the pin.

[0039] like Figure 1 As shown, in a preferred embodiment, the snap-fit ​​arm further includes an insertion section 35, which is integrally connected to the free end of the second limiting section 34. The insertion section 35 is inclined away from the insertion arm 31 and forms an insertion opening with the insertion arm 31. By providing the insertion section, it is convenient to insert the pin into the limiting channel.

[0040] like Figure 1 , Figure 2 and Figure 5 As shown, the buckle body 1 in this embodiment includes an arc-shaped body 11, a first insertion plate 12, and a second insertion plate 13. The first insertion plate 12 and the second insertion plate 13 are integrally connected to both ends of the arc-shaped body 11. The first insertion plate 12 and the second insertion plate 13 are arranged in parallel opposite directions. The first insertion plate 12 has a first insertion hole, and the second insertion plate 13 has a second insertion hole. By providing the first and second insertion plates, it is convenient to form insertion holes for mating and insertion with the pin.

[0041] like Figure 1 and Figure 2 As shown, the central axes of the first and second insertion holes in this embodiment are perpendicular to the central axis of the arc-shaped body 11.

[0042] like Figure 1 and Figure 2As shown, in this embodiment, the first plug-in plate 12 and the second plug-in plate 13 are also circular structures. The central axis of the first plug-in hole coincides with the central axis of the first plug-in plate 12, and the central axis of the second plug-in hole coincides with the central axis of the second plug-in plate 13.

[0043] This embodiment of a steel structure pipe column installation and hoisting mechanism, by setting up a buckle body, pin shaft, pin sleeve, and release rope, allows the buckle body, pin shaft, and pin sleeve to be installed on the top of the steel pipe column. The release rope is connected to the pin sleeve. After hoisting and installation, when the hoisting mechanism is not under stress, workers on the ground can pull the release rope to release the pin shaft and complete the unhooking operation. This hoisting mechanism avoids the problem of workers needing to climb to the hoisting point using a special steel structure ladder after the steel pipe column is installed, solving the safety problem of workers climbing to heights and reducing the installation time of the steel pipe column, thus ensuring the safety of the installation and hoisting of the steel structure pipe column. This hoisting device is applicable to steel structure pipe columns of different sizes and has strong practicality.

[0044] like Figures 3-5 As shown, the installation structure of a steel structure steel pipe column installation and hoisting mechanism in this embodiment includes the above-mentioned steel structure steel pipe column installation and hoisting mechanism, and also includes a steel pipe column 5. The buckle body 1 is sleeved on the top connecting plate 51 of the steel pipe column 5, and the pin shaft 2 passes through the top connecting plate 51 of the steel pipe column 5 and the first insertion hole and the second insertion hole of the buckle body 1.

[0045] like Figures 3-5 As shown, the steel structure steel pipe column installation and hoisting mechanism of this embodiment has two parts. The two buckles 1 are respectively sleeved on the two top connecting plates 51 on the upper ends of the two sides of the steel pipe column 5. The pin sleeves 3 on the two pin shafts 2 are arranged adjacent to each other, and the clamping joints 22 of the two pin shafts 2 are arranged far apart from each other. The other ends of the two release ropes 4 are respectively placed on the lower sides of the steel pipe column 5.

[0046] The installation structure in this embodiment installs the hoisting mechanism on top of the steel pipe column, which improves hoisting safety, enhances hoisting stability, increases installation efficiency, avoids the need for working at heights during steel structure installation, and ensures the safety of construction operations.

[0047] After the installation structure of this embodiment is completed, the steel pipe column can be lifted by suspending the steel wire rope 6 at the top of the steel pipe column using the hook 7. The steel wire rope 6 passes through the buckle 1 at the top of the steel pipe column. During the lifting process by the lifting equipment, the release rope should not be under stress and should rise with the steel pipe column. After the steel pipe column is installed, the lifting equipment slightly lowers the hook. With the buckle body under no stress, the worker uses the release rope to pull out the pin, and finally the lifting equipment retracts the hook and arm. Finally, this device achieves the purpose of automatic release.
