Description

Technical Field

[0001] The present application relates to the technical field of steel column construction, and in particular to a steel column hoisting device. Background Art

[0002] Steel column refers to the high-rise building that places steel in the column to compress the concrete column section to enhance the column's bearing capacity. Steel column hoisting refers to the suspension and displacement of the steel column in the construction site and its installation to the designated location.

[0003] At present, cranes are usually used to lift steel columns. The cranes are mainly composed of an operating mechanism, a lifting mechanism, a slewing mechanism, a hydraulic arm, and a hanging mechanism. During the lifting process, one end of the steel column needs to be tied with a wire rope and fixed to the hanging mechanism before lifting. When the crane lifts the steel column off the ground and rotates it through the slewing mechanism to transfer the steel column to the designated construction location, the steel column is prone to swing back and forth when hoisted in mid-air due to inertia, which may cause safety hazards.

[0019] The following is combined with Figure 1-3This application is described in further detail.

[0020] The embodiment of the present application discloses a steel column hoisting device.

[0021] Reference Figure 1 The steel column hoisting device includes a suspension mechanism 1 hooked on a hydraulic arm, a traction assembly 21, and a gripping assembly 3 detachably connected to the side wall of the steel column. The suspension mechanism 1 includes a fixed block 11 arranged on the crane hanging mechanism. A first lifting ring 12 is welded on the top of the fixed block 11. Two lifting ropes 13 of the same length are fixedly installed at the bottom of the fixed block 11. The other end of the lifting rope 13 is connected to one end of the steel column. Two lifting ears 14 are fixedly installed at one end of the steel column. The two lifting ears 14 are symmetrically distributed at the connection between the horizontal steel plate and the vertical steel plate of the steel column. The lifting rope 13 is tied and connected to the lifting ears 14. When the crane hoists the steel column, the first lifting ring 12 is hooked to drive the fixed block 11 to rise, thereby driving the lifting rope 13 at the bottom of the fixed block 11 to rise. Since the two lifting ropes 13 are of the same length and the angles connected to the fixed block 11 are the same, the deviation of the angle of the steel column during the hoisting process can be reduced, thereby reducing the center of gravity deviation and reducing safety hazards.

[0022] Reference Figure 1 The traction assembly 21 includes a hydraulic cylinder 213 and a telescopic rod 211. The hydraulic cylinder 213 is fixedly connected to the hydraulic arm, the output end of the hydraulic cylinder 213 is fixedly connected to the telescopic rod 211, and the lower end of the telescopic rod 211 is welded to the top of the first pulley 212 support.

[0023] Reference Figure 2 The horizontal plate 22 is provided with a slide groove 221 along the length direction, and the slide groove 221 is slidably connected with the second pulley 214. A screw rod 222 is rotatably connected in the slide groove 221, and a slider 223 is threadedly connected to the screw rod 222. The slider 223 is slidably connected in the slide groove 221, and the slider 223 is fixedly connected to the second pulley 214, so that the slider 223 can slide in the slide groove 221 to drive the second pulley 214 to slide. The first pulley 212 and the second pulley 214 are always located on the same vertical parallel plane, and the axes of the first pulley 212 and the second pulley 214 are parallel. A servo motor 23 is fixedly connected to one end of the horizontal plate 22, and the output end of the servo motor 23 is fixedly connected to the screw rod 222. A cover box 24 is provided on the outer side of the servo motor 23, and one side of the cover box 24 can be opened or closed, thereby reducing the probability of the servo motor 23 being damaged by rain and wind.

[0024] Reference Figure 1A steel wire rope 15 is passed through the first pulley 212, the second pulley 214 and the gripping assembly 3. When the angle of the hydraulic arm changes, the position of the first pulley 212 will be shifted. The steel wire rope 15 can be kept in a taut state by adjusting the horizontal position of the second pulley 214 or by appropriately adjusting the lifting position of the first pulley 212 without hindering the operation of the crane, thereby reducing the swinging of the steel column due to inertia.

[0025] Reference Figure 3 The gripping assembly 3 includes two L-shaped first gripping clips 31 and second gripping clips 32. One end of the first gripping clip 31 is slidably inserted into the second gripping clip 32. The ends of the first gripping clip 31 and the second gripping clip 32 that are away from each other are respectively abutted against the sides of the steel column. Bolts 35 are threadedly connected to the first gripping clip 31 and the second gripping clip 32. A plurality of mounting holes 36 for inserting the bolts 35 are longitudinally opened and transversely distributed on the first gripping clip 31 and the second gripping clip 32. By adjusting the distance of the first gripping clip 31 and inserting the bolts 35 into the corresponding mounting holes 36, steel columns of different sizes can be fixed. The ends of the first gripping clip 31 and the second gripping clip 32 that abut against the side wall of the steel column are respectively provided with rubber pads 33. The rubber pads 33 can increase the friction between the first gripping clip 31 and the second gripping clip 32 and the steel column and can prevent the first gripping clip 31 and the second gripping clip 32 from directly contacting the steel column, thereby reducing wear. A second lifting ring 34 is welded to the end surface of the second grabbing clamp 32 facing away from the steel column, and the steel wire rope 15 passes through the second lifting ring 34 to connect the first pulley 212 and the second pulley 214 .

[0026] Implementation principle:

[0027] When the steel column needs to be hoisted, the steel column is placed in a suitable position, two lifting ears 14 are fixed at one end of the steel column, the lifting rope 13 is firmly tied to the lifting ear 14, the first grab clamp 31 is adjusted to a suitable position, the first grab clamp 31 and the second grab clamp 32 are fixed by bolts 35, so that the first grab clamp 31 and the second grab clamp 32 are fixed to the side wall of the steel column, the wire rope 15 passes through the second lifting ring 34 and the first pulley 212 and the second pulley 214 and fixes the two ends in a closed state, the first lifting ring 12 on the fixed block 11 is hooked up by the crane hanging mechanism, the steel column is first hoisted to a state perpendicular to the ground, the first pulley 212 is lifted and lowered by the hydraulic cylinder 213 and adjusted to a position that does not hinder the operation of the hydraulic arm, the position of the second pulley 214 is adjusted by the servo motor 23, so that the wire rope 15 is always in a tensioned state, and finally the crane is operated to lift and lower, thereby slowing down the swinging back and forth of the steel column due to inertia during hoisting.

[0028] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
