For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0038] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0039] As Figure 1 shown, it is a preferred embodiment of the hoisting auxiliary device of the present utility model. Such a hoisting auxiliary device can be used as an auxiliary tool when hoisting items, and is particularly suitable for hoisting H-shaped steel beams.

[0040] The above-mentioned hoisting auxiliary device includes: a lifting lug plate 1, two clamping plates 2, a first fastener, and a connecting buckle 4. A first connection hole is formed on the lifting lug plate 1, and the connecting buckle 4 is connected to the first connection hole, and the lifting equipment is connected to the connecting buckle 4. The two clamping plates 2 are arranged on the lifting lug plate 1 at intervals along the height direction of the lifting lug plate 1. The upper flange plate of the steel beam 3 is located between the two clamping plates 2, and a second connection hole is formed on the clamping plate 2, and a hoisting hole is formed on the upper flange plate, and the hoisting hole corresponds to the two second connection holes. The first fastener is arranged in the second connection hole and the hoisting hole, and the steel beam 3 is connected to the hoisting auxiliary device through the first fastener. Then, the steel beam 3 can be lifted by the lifting equipment, and later the steel beam 3 can be separated from the hoisting auxiliary device by removing the first fastener. Such a hoisting auxiliary device is detachable. After using such a hoisting auxiliary device, there is no need to weld before hoisting, and there is no need for hot cutting at high altitude later, which brings convenience to the construction.

[0041] Specifically, as Figures 2 to 4As shown, two clamping plates 2 are arranged at the bottom of the lug plate 1, and the bottom surface of one of the clamping plates 2 located below is flush with the bottom surface of the lug plate 1. The two clamping plates 2 are both rectangular plates, and the second connection holes formed thereon are coaxially arranged. The first connection hole is formed at one end of the lug plate 1 away from the clamping plate 2.

[0042] Furthermore, as Figure 5 shown, the hoisting auxiliary device further includes a backing plate 6. The backing plate 6 is located between the upper flange plate and the clamping plate 2. And a third connection hole is formed on the backing plate 6, and the third connection hole corresponds to the hoisting hole and the second connection hole. When connecting with the upper flange plate of the steel beam 3, since the thickness dimensions of the upper flange plates of different models of steel beams 3 are different, but the distance between the two clamping plates 2 is fixed, so when the distance between the two clamping plates 2 is greater than the thickness of the upper flange plate, the backing plate 6 can be set to fill the gap between the upper flange plate and the clamping plate 2. The backing plate 6 can be arranged between the top surface of the upper flange plate and the upper clamping plate 2, or can be arranged between the bottom surface of the upper flange plate and the lower clamping plate 2. After setting the backing plate 6, it can ensure the stability and safety of the steel beam 3 during hoisting. In this embodiment, the backing plate 6 is preferably a wooden board, so that when setting the backing plate 6, the surface of the steel beam 3 will not be damaged due to friction, and the wooden board is also relatively common at the construction site and can be obtained locally.

[0043] The first fastener includes: a bolt and a nut. The bolt is arranged in the hoisting hole and the two second connection holes, and one end of the bolt abuts against the clamping plate 2, and a nut is arranged at the other end. And when there is a backing plate 6 between the clamping plate 2 and the upper flange plate, the bolt also needs to pass through the second connection hole on the backing plate 6. The upper flange plate can be connected with the hoisting auxiliary device through the first fastener.

[0044] In other embodiments, the first fastener can also be a pin shaft or the like.

[0045] Furthermore, the hoisting auxiliary device further includes a support assembly, and the support assembly is connected with the lug plate 1 and the upper clamping plate 2 among the two clamping plates 2. Specifically, the support assembly includes: two stiffening ribs 51, and the two stiffening ribs 51 are respectively arranged on both sides of the lug plate 1, and the cross section of the stiffening rib 51 is triangular.

[0046] In other embodiments, the stiffening rib 51 can also be in other shapes such as a square plate.

[0047] Furthermore, the connecting buckle 4 includes: a lifting ring 41 and a second fastener 42. The second fastener 42 passes through the first connection hole, and both ends of the second fastener 42 are connected with the lifting ring 41. The second fastener 42 and the lifting ring 41 are also detachably connected. Specifically, in this embodiment, the connecting buckle 4 is preferably a bow shackle, that is, the lifting ring 41 is in a bow shape, and the second fastener 42 is threadedly connected with the lifting ring 41.

[0048] The usage process of the hoisting auxiliary device provided in this embodiment is described as follows:

[0049] First, place the H-shaped steel beam 3 to be hoisted on the ground so that the upper flange is parallel to the ground. Then, set hoisting auxiliary devices on both sides of the upper flange, and the number of hoisting auxiliary devices set on each side is determined according to the length of the steel beam 3.

[0050] The installation process of the hoisting auxiliary device is as follows: Place the upper flange between the two clamping plates 2, and then insert the backing plate 6 into the gap according to requirements. Then align the second connection hole, the third connection hole, and the hoisting hole, then insert the bolt, and finally screw on the nut. Then connect the hoisting equipment to the connecting buckle 4, and the steel beam 3 can be hoisted. After hoisting to the designated position, remove the bolt and nut, and the hoisting auxiliary device can still be used cyclically.

[0051] Obviously, the above embodiments are only examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
