Description
Technical Field
[0001] The utility model belongs to the technical field of hoisting devices, and particularly relates to a hoisting device for steel structure beams. Background Technique
[0002] The I-shaped beam is a relatively common structural form in steel structure beams. At present, in the process of producing I-shaped beams, it is necessary to hoist the I-shaped beams between various processes. When the existing hoisting devices are in use, most of them drive the spreader to hoist the I-shaped beam by winding and unwinding the steel wire rope. However, during the hoisting process of the I-shaped beam, the I-shaped beam sometimes moves on the spreader. Coupled with the influence of the swing of the steel wire rope, there will be a safety hazard that the I-shaped beam will fall from a high place. Therefore, there are still disadvantages and deficiencies in the prior art. Content of the Utility Model
[0003] The purpose of the utility model is to provide a hoisting device for steel structure beams to solve the problems raised in the above background technique.
[0004] The technical solutions adopted by the utility model to solve the above problems are as follows:
[0005] A hoisting device for steel structure beams includes a gantry with a crossbeam and capable of moving. A electric hoist with a hook is slidably connected to the crossbeam of the gantry. A horizontally arranged hanging plate is hung on the hook of the electric hoist. Two sets of vertically opposite and telescopic anti-sway mechanisms are installed between the hanging plate and the electric hoist. And two sets of symmetrically distributed hoisting devices are installed at both ends of the bottom surface of the hanging plate. The hoisting devices both include vertically distributed telescopic mechanisms. The top ends of the telescopic mechanisms are respectively connected to the hanging plate. The bottom ends of the telescopic mechanisms are all movable ends and are detachably installed with hanging frames. The hanging frames both include connecting plates perpendicular to the hanging plate in the horizontal direction. The connecting plates and the bottom ends of the telescopic mechanisms are respectively detachably and fixedly connected. And both ends of the bottom surface of the connecting plate are fixedly connected with vertically arranged L-shaped hooks. The two L-shaped hooks on each connecting plate are symmetrically arranged. And vertical jacking screws penetrating through the connecting plate are also threadedly connected at both ends of each connecting plate.
[0006] Further, the telescopic mechanisms both include mounting plates arranged parallel to the hanging plate. The four corners of the mounting plates and the hanging plate are connected by connecting bolts. And vertically distributed fixed pipes are fixedly connected to the bottom surfaces of the mounting plates. Movable rods are slidably connected in the fixed pipes. The bottom ends of the movable rods are located outside the fixed pipes and are respectively detachably and fixedly connected to the connecting plates. And guiding and limiting components capable of preventing the movable rods from slipping off the fixed pipes are also arranged between the movable rods and the fixed pipes.
[0007] Further, the guiding and limiting assembly includes two slideways which are arranged in parallel with the fixed pipe and symmetrically opened on both side walls of the fixed pipe. There is a gap between the bottom end of each slideway and the bottom end of the fixed pipe, and a slider is slidably connected in each slideway. The sliders are respectively fixedly connected to the top of the movable rod.
[0008] Further, threaded holes are horizontally opened at the bottom of the movable rods, vertical connecting pipes are fixedly connected to the top surfaces of the connecting plates, and connecting screws horizontally penetrating through the connecting pipes are threadedly connected to the connecting pipes. The connecting screws are respectively opposite to the positions of the threaded holes.
[0009] Further, a handle located outside the fixed pipe is fixedly connected to one of the sliders of each group of guiding and limiting assemblies.
[0010] Further, casings are fixedly sleeved at both ends of the electric hoist. The anti-sway mechanism is a multi-section telescopic rod, and both ends of the anti-sway mechanism are respectively fixedly connected to the casing and the hanging plate.
[0011] Further, the gantry is a movable gantry with a steering function.
[0012] Adopting the above technical solution, the beneficial effects of the present utility model are as follows:
[0013] Based on the existing gantry, electric hoist and hanging plate, the present utility model can reduce the swing amplitude of the hanging plate by arranging two groups of anti-sway mechanisms. Secondly, in use, by arranging the L-shaped hook and the top-tightening screw, the I-beam can be fixed on the hanging frame, so that during the hoisting process of the I-beam, the I-beam can be prevented from moving on the hoisting device, thereby reducing the safety hazard of the I-beam falling from a high place.

Detailed implementation manners
[0020] To make the objectives, technical solutions and beneficial effects of the present utility model clearer, the following further describes in detail the implementation manners of the present utility model with reference to the accompanying drawings.
[0021] As Figures 1 to 5 shown, the present utility model provides a hoisting device for a steel structure beam, including a gantry 6 with a cross beam 61 and capable of moving. During use, the gantry 6 can drive the entire hoisting device to move; a electric hoist 5 with a hook 51 is slidably connected to the cross beam 61 of the gantry 6, and a horizontally arranged hanging plate 4 is hung on the hook 51 of the electric hoist 5. Specifically, the electric hoist 5 is a prior art, that is, the electric hoist 5 further includes a steel wire rope, a drum device, a driving wheel, etc. During use, the electric hoist 5 can move along the cross beam 61, and the electric hoist 5 can drive the hanging plate 4 to lift and lower by winding and unwinding the steel wire rope; two groups of vertically and oppositely distributed and telescopic anti-sway mechanisms 3 are installed between the hanging plate 4 and the electric hoist 5. During use, the anti-sway mechanisms 3 can telescopically move synchronously with the lifting and lowering of the hanging plate 4, so as to reduce the swing amplitude of the hanging plate 4.
[0022] Secondly, two sets of symmetrically distributed hoisting devices are installed at both ends of the bottom surface of the hanging plate 4. Each hoisting device includes a vertically distributed telescopic mechanism 2. The top ends of the telescopic mechanisms 2 are all connected to the hanging plate 4, and the bottom ends of the telescopic mechanisms 2 are all movable ends and are detachably installed with hanging frames 1. In the initial state, the telescopic mechanisms 2 are in the extended state; each hanging frame 1 includes a connecting plate 11 perpendicular to the hanging plate 4 in the horizontal direction. The connecting plate 11 and the bottom end of the telescopic mechanism 2 are respectively detachably and fixedly connected, which facilitates the disassembly and assembly of the hanging frame 1 on the telescopic mechanism 2; and both ends of the bottom surface of the connecting plate 11 are fixedly connected with vertically arranged L-shaped hooks 12. The two L-shaped hooks 12 on each connecting plate 11 are symmetrically arranged, and vertical jacking screws 13 vertically penetrating the connecting plate 11 are threadedly connected to both ends of each connecting plate 11. Specifically, a handle is fixedly sleeved on the top end of the jacking screw 13, and the jacking screw 13 is respectively opposite to the horizontal hook position of the L-shaped hook 12; during use, first move the hoisting device above the I-beam 8, and then when the hoisting device is driven by the electric hoist 5 to descend to a certain height, the hanging frame 1 can be removed from the telescopic mechanism 2. At this time, the hanging frame 1 can be sleeved on the upper flange 81 of the I-beam 8 from both ends of the I-beam 8 respectively, and at the same time, continue to drive the hoisting device to descend until the bottom end of the telescopic mechanism 2 abuts against the upper flange 81. Then when the hanging frame 1 moves along the I-beam 8 to a position opposite to the telescopic mechanism 2, the hanging frame 1 can be reinstalled on the telescopic mechanism 2, and then the telescopic mechanism 2 is retracted until the L-shaped hook 12 abuts tightly against the upper flange 81, and then by rotating the jacking screw 13, the bottom end of the jacking screw 13 is abutted tightly against the upper flange 81, so that the I-beam 8 can be fixed on the hanging frame 1. Then when the electric hoist 5 drives the hanging plate 4 to rise, the telescopic mechanism 2 can be fully extended, so that during the hoisting process of the I-beam 8, the I-beam 8 can be prevented from moving on the hoisting device, thereby reducing the safety hazard of the I-beam 8 falling from a high place.
[0023] The specific setting method of the telescopic mechanism 2 is as follows: As Figures 1 to 5As shown, the telescopic mechanism 2 includes a mounting plate 21 arranged in parallel with the hanging plate 4. The four corners of the mounting plate 21 are connected to the hanging plate 4 by connecting bolts. Specifically, when the mounting plate 21 is connected to the hanging plate 4, the screw end of the connecting bolt passes through the mounting plate 21 and is threadedly connected to the hanging plate 4, and the head of the connecting bolt abuts against the mounting plate 21, which facilitates the disassembly and assembly of the telescopic mechanism 2 on the hanging plate 4. And vertically distributed fixed tubes 22 are fixedly connected to the bottom surface of the mounting plate 21. Movable rods 23 are slidably connected in the fixed tubes 22. The bottom ends of the movable rods 23 are located outside the fixed tubes 22 and are respectively detachably and fixedly connected to the connecting plates 11. Specifically, during use, when the movable rods 23 slide along the fixed tubes 22, the telescopic movement of the telescopic mechanism 2 can be realized. And a guiding and limiting component 24 for preventing the movable rods 23 from slipping off the fixed tubes 22 is arranged between the movable rods 23 and the fixed tubes 22. In this way, when the telescopic mechanism 2 is fully extended, the movable rods 23 can be prevented from falling off the fixed tubes 22.
[0024] The specific setting method of the guiding and limiting component 24 is as follows: As Figures 2 to 4 shown, the guiding and limiting component 24 includes two slideways 241 arranged in parallel with the fixed tube 22 and symmetrically opened on both side walls of the fixed tube 22. There is a gap between the bottom end of each slideway 241 and the bottom end of the fixed tube 22, and a slider 242 is slidably connected in each slideway 241. The sliders 242 are respectively fixedly connected to the top of the movable rod 23. Specifically, when the movable rod 23 slides along the fixed tube 22, the sliders 242 can slide along the slideways 241 respectively. At this time, the sliders 242 and the slideways 241 can guide the movable rod 23 to improve the stability of the movable rod 23 during the sliding process. And when the slider 242 moves to the bottom end of the slideway 231, that is, when the telescopic mechanism 2 is fully extended, since there is a gap between the bottom end of each slideway 241 and the bottom end of the fixed tube 22, the movable rod 23 can be prevented from slipping off the fixed tube 22.
[0025] The specific setting method of the detachable and fixed connection between the bottom end of the movable rod 23 and the connecting plate 11 is as follows: As Figure 2 、 Figure 4 and Figure 5As shown in the figure, threaded holes 231 are horizontally formed at the bottoms of the movable rods 23. Vertically distributed connecting pipes 14 are fixedly connected to the top surfaces of the connecting plates 11. Connecting screws 15 that horizontally penetrate through the connecting pipes 14 are threadedly connected to the connecting pipes 14. The positions of the connecting screws 15 are opposite to those of the threaded holes 231. Specifically, handles are fixedly sleeved on the outer ends of the connecting screws 15. When in use, when it is necessary to reinstall the hanging bracket 1 on the telescopic mechanism 2, the movable rod 23 can be first lifted upward. Then, after aligning the position of the connecting pipe 14 with that of the movable rod 23, the bottom end of the movable rod 23 can be inserted into the connecting pipe 14. At this time, the positions of the connecting screws 15 are opposite to those of the threaded holes 231. Then, by rotating the connecting screws 15 and threadedly connecting the connecting screws 15 with the movable rod 23 through the threaded holes 231, the hanging bracket 1 can be installed on the telescopic mechanism 2, thereby facilitating the disassembly and assembly of the hanging bracket 1 on the telescopic mechanism 2.
[0026] To facilitate the sliding of the movable rod 23 along the fixed pipe 22, therefore, as Figures 1 to 5 shown in the figure, a handle 25 located outside the fixed pipe 22 is fixedly connected to one of the sliders 242 of each set of guiding and limiting assemblies 24. Specifically, by providing the handle 25, it is convenient to lift and place the movable rod 23, thereby facilitating the sliding of the movable rod 23 along the fixed pipe 22.
[0027] The specific setting method of the anti-sway mechanism 3 is as follows: As Figure 1 shown in the figure, casings 7 are fixedly sleeved at both ends of the electric hoist 5. The anti-sway mechanism 3 is a multi-section telescopic rod. The two ends of the anti-sway mechanism 3 are respectively fixedly connected to the casing 7 and the hanging plate 4. Specifically, during the descending process of the hanging plate 4, under the action of the self-weight of the hanging plate 4 and the hoisting device, the multi-section telescopic rod can be extended; during the ascending process of the hanging plate 4, by pushing the multi-section telescopic rod, the multi-section telescopic rod can be retracted. In this way, during the lifting and lowering process of the hanging plate 4, the multi-section telescopic rod can be telescopically synchronized, thereby reducing the swaying amplitude of the hanging plate 4.
[0028] Furthermore, as Figure 1 shown in the figure, the gantry 6 is a movable gantry with a steering function. Specifically, a driving mechanism with a steering function and tire-type traveling wheels in the prior art are installed at the bottom of the gantry 6, which is more convenient for the hoisting device to hoist the I-beam 8.
