Steel structure needs to withstand various possible natural and man-made environmental effects and is an engineering structure and building with sufficient reliability and good social and economic benefits.

[0003] During the use of the existing steel structure profile lifting device, the staff needs to first fix the traction rope on the steel structure, and then use the lifting equipment to lift it. Because the center point of the steel structure is difficult to determine when fixing the traction rope, the center of gravity of the steel structure is offset during the lifting process, which is inconvenient to use and reduces work efficiency.

[0004] After checking the public (announcement) number: 202021784240.2, a steel structure profile lifting device is disclosed. This technology discloses "by setting a positioning plate, a mounting frame, a fixed suction cup and a mounting hole, the staff can place the positioning plate in the center of the steel structure, and then fix the positioning plate through the fixed suction cup, and install the lifting ring in the mounting hole at the same distance", etc., which has the technical effects of "avoiding the displacement of the steel structure during the lifting process, facilitating use, and improving work efficiency";

[0005] However, in the above scheme, when adjusting the position of the fixing frame, it is necessary to first loosen the fixing bolts, then move the fixing frame to a suitable fixing hole position on the connecting plate, and finally tighten the fixing bolts to fix it. Since the fixing frames on both sides need to be adjusted, the adjustment process is more troublesome, which affects the processing efficiency.

[0006] In order to solve the above problems, the present application proposes a lifting device for steel structure profiles. Utility Model Content

A slide frame 13 is fixed at the bottom, and sliders 14 are slidably connected on both sides of the interior of the slide frame 13. A clamping plate 15 is fixed at the bottom of the slider 14, and lifting rings 21 are fixed on both sides of the top of the beam 1. In this embodiment, when the mounting seat 4 needs to be removed from the beam 1, the pull ring 11 is pulled upward. When the pull ring 11 drives the semicircular groove 10 on the pin block 9 to align with the semicircular block 7, the semicircular block 7 is pushed into the interior of the semicircular groove 10 by the rebound pressure of the first spring 8, and at the same time, the locating pin 6 is also driven to disengage from the fixing hole 5, so that the mounting seat 4 can be removed from the lower end of the beam 1, and the mounting seats 4 on both sides can be installed at the corresponding lower ends of the beam 1 according to the length of the hoisted steel structure profile.

[0025] Specifically, a bidirectional screw rod 16 is rotatably connected between the two ends of the inner part of the slide frame 13, and an inner hexagonal hole 17 is provided on the surface of the two end surface of the bidirectional screw rod 16. In this embodiment, the bidirectional screw rod 16 is rotated by inserting an inner hexagonal hole 17 with a hexagonal wrench. The bidirectional screw rod 16 drives the clamping plates 15 on both sides through the sliders 14 on both sides to clamp and fix the steel structure profile.

[0026] Specifically, the outer surfaces of both ends of the bidirectional screw rod 16 are respectively connected to the internal threads of the sliders 14 on both sides. In this embodiment, when the bidirectional screw rod 16 rotates, it can drive the sliders 14 on both sides to move synchronously in the opposite direction along the inside of the slide frame 13.

[0027] Specifically, guide rods 18 are slidably connected to the inside of the upper ends of the clamps 15, and a pressure plate 19 is fixed between the bottoms of the guide rods 18 on both sides. A third spring 20 is sleeved on the outer surface of the guide rods 18. In this embodiment, after the clamps 15 on both sides clamp and fix the steel structure profile, the rebound pressure of the third spring 20 drives the pressure plate 19 to limit the steel structure profile to avoid up and down shaking during lifting.

[0028] Specifically, a second spring 12 is sleeved on the outer surface of the upper end of the pin block 9. In this embodiment, when the mounting seat 4 needs to be installed at the required position at the lower end of the beam 1, the pull ring 11 is pulled upward to disengage the positioning pin 6 from the interior of the fixing hole 5, and the fixing head 2 at the bottom of the beam 1 is inserted into the interior of the fixing hole 5 at the top of the mounting seat 4. The pulled pull ring 11 is then released, and the pin block 9 is pushed downward under the pressure of the rebound of the second spring 12. At the same time, the semicircular groove 10 on the pin block 9 is disengaged from the semicircular block 7, so that the surface of the pin block 9 pushes the semicircular block 7 to drive the positioning pin 6 to extend into the interior of the fixing hole 5, and at the same time, the positioning pin 6 is also inserted into the positioning groove 3 on the fixing head 2, thereby fixing the mounting seat 4 to the lower end of the beam 1.

[0029] Specifically, a key bar 22 is fixed to the outer surface of the pin block 9 . In this embodiment, the key bar 22 can prevent the pin block 9 from rotating when it moves up and down, so that the semicircular groove 10 on the pin block 9 always faces the semicircular block 7 .

[0030] The working principle and use process of the utility model are as follows: first, the mounting seats 4 on both sides are installed at the corresponding lower ends of the beams 1 according to the hoisted steel structure profiles. When the mounting seats 4 need to be installed at the lower ends of the beams 1, the pull ring 11 is pulled upwards. When the pull ring 11 drives the semicircular groove 10 on the pin block 9 to align with the semicircular block 7, the semicircular block 7 is pushed into the semicircular groove 10 by the pressure of the first spring 8 rebounding, and at the same time, the positioning pin 6 is also driven to disengage from the fixing hole 5, and the fixing head 2 at the bottom of the beam 1 is inserted into the fixing hole 5 at the top of the mounting seat 4, and then the pulled pull ring 11 is released, and the pin block 9 is pushed downward under the pressure of the second spring 12 rebounding. Move, and at the same time, the semicircular groove 10 on the pin block 9 is separated from the semicircular block 7, so that the surface of the pin block 9 pushes the semicircular block 7 to drive the positioning pin 6 to extend into the interior of the fixing hole 5, and at the same time, the positioning pin 6 is also inserted into the interior of the positioning groove 3 on the fixing head 2, so that the mounting seat 4 is fixed to the lower end of the beam 1; then, by using an inner hexagonal wrench to insert the inner hexagonal hole 17 to rotate the two-way screw rod 16, the two-way screw rod 16 drives the clamping plates 15 on both sides through the sliders 14 on both sides to clamp and fix the steel structure profile; finally, the hook is hooked on the two lifting rings 21 on the top of the beam 1 and lifts it, so that the steel structure profile is balanced and stable during the lifting process.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
