Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel column lifting, in particular to a steel column lifting hoist. Background Art
[0002] Existing steel columns are typically hoisted by directly wrapping steel ropes around the columns, or by wrapping steel ropes around pre-set lifting lugs at the ends of the columns, and then hoisting the columns with a crane. However, using steel ropes to hoist the columns can easily cause them to swing in mid-air, making butt welding difficult. Furthermore, operators need to weld the entire end of the column, which is extremely inconvenient as the work is done in mid-air, making it difficult to move the welders mid-air and perform stable and portable welding.
[0003] Therefore, the present invention provides a steel column lifting hoist to solve the above problems. Utility Model Content

[0026] The embodiment of the present disclosure aims to solve the problem that existing steel columns are not easy to connect and weld when they are hoisted. In view of this, the embodiment of the present disclosure proposes a steel column hoisting hoop, see Figure 1As can be seen, it includes an upper hoop 1 and a lower hoop 2. The two ends of the upper hoop 1 and lower hoop 2 are fixedly connected by bolts, and the other ends of the upper hoop 1 and lower hoop 2 are fixedly connected by bolts, so that when the bolts are fixed, they form a complete annular hoop. The upper hoop 1 and lower hoop 2 are evenly arranged with lifting lugs 6 for lifting. The inner circumference of the upper hoop 1 and lower hoop 2 is fixed with multiple electromagnetic jacks 7. By energizing the electromagnetic jacks 7, the internal iron cores of the electromagnetic jacks 7 are magnetized, thereby attracting the steel column and lifting it. An isolation layer is also fixed between the upper hoop and the lower hoop. This isolation layer is used to prevent the electromagnetic jacks from affecting the internal structure of the upper and lower hoops, thereby isolating the electromagnetic jacks from the interior of the upper and lower hoops. Lifting lugs 6 are fixedly installed on either side of the upper hoop 1 and lower hoop 2, and these lifting lugs 6 are used to connect to the fixed steel rope for lifting.
[0027] It should be noted that the electromagnetic jack 7 is not used in this embodiment. The steel column can be fixed and lifted by only fixing the steel column with the upper clamp 1 and the lower clamp 2. The function of the electromagnetic jack 7 is to make the lifting more stable and secure. The lifting lug 6 in this embodiment is located radially of the upper clamp 1 and the lower clamp 2. The position of the lifting lug 6 can also be adaptively changed. For example, the lifting lug 6 can be changed to be axially arranged with the upper clamp 1 and the lower clamp 2, so that the steel column can be lifted in a horizontal state.
[0028] See also Figures 1 to 4 It can be seen that the axial side surfaces of the upper clamp 1 and the lower clamp 2 are both provided with axial grooves 3, and an arc block 4 is slidably installed in the axial groove 3. The circumferential side of the arc block 4 is protruded with a mounting wall 41, and a telescopic rod 42 is fixedly installed on the surface of the mounting wall 41. A welding device 43 for welding is fixedly installed on the parallel side of the telescopic rod 42. The welding device 43 is a welding gun, and the telescopic rod 42 is an electric telescopic rod 42. A moving component 44 and an extension plate 5 are fixedly installed on the other circumferential side of the arc block 4. The arc block 4 and the extension block are fixedly connected by an arc connector. The moving component 44 drives the arc block 4 to slide in the axial groove 3. The extension plate 5 can be close to the welded steel column, thereby reducing the docking error during the welding process of the hoisted steel column. The axial length of the extension plate 5 is greater than that of the arc block 4.
[0029] It should be noted that after the ends of the upper and lower clamps 1 and 2 are fixed by bolts to form a complete annular clamp, the end of the steel column is exposed beyond the upper and lower clamps 1 and 2, thereby ensuring that the welding gun can weld the end of the steel column. The electric telescopic rod 42 can drive the welding gun to move along the axial direction of the upper and lower clamps 1 and 2, so as to flexibly adjust the welding of the steel column end, improve the flexibility during welding, and avoid the error of the steel column end from the upper and lower clamps 1 and 2 when the steel column is hoisted, which may cause welding failure.
[0030] By loosening the bolts, the ends of the upper clamp 1 and the lower clamp 2 are separated and opened, and then the upper clamp 1 and the lower clamp 2 are placed on both sides of the steel column respectively, and then the upper clamp 1 and the lower clamp 2 are tightened by bolts. After the upper clamp 1 and the lower clamp 2 are docked, the upper clamp 1 and the lower clamp 2 are fixed by bolts, and then the electromagnetic jack 7 is energized to magnetize the iron core inside the electromagnetic jack 7, thereby adsorbing the steel column to complete the fixation of the steel column, and then the clamp in the embodiment of the present disclosure can be lifted by a gantry crane or a crane. After lifting the clamp in the present disclosure, in the process of preparing for welding, the extension plate 5 can be close to the fixed steel structure, so that the steel column and the welded steel structure can be stably docked. After the docking is completed, the moving assembly 44 drives the arc block 4 to slide in the axial groove 3, so that the arc block 4 can drive the welding gun to move circumferentially, and then the welding gun can weld along the end of the steel column.
[0031] It is through the mutual cooperation of the upper clamp 1, the lower clamp 2, the extension plate 5 and the arc block 4 that the error in the butt welding process can be reduced. At the same time, they cooperate with the drive assembly to reduce the error in the butt welding process while enabling the welding gun to stably weld along the end of the steel column.
[0032] The moving assembly 44 includes a motor 441 and a driving wheel 442. The motor 441 is fixedly installed on the side wall of the arc block 4 circumferentially away from the welding device 43. The motor 441 is a bidirectional motor 441 that can rotate forward and reverse. The motor 441 is close to any radial inner wall of the axial groove 3. The driving wheel 442 is fixedly installed on the output shaft of the motor 441, and the driving wheel 442 is in contact with any radial inner wall of the axial groove 3.
[0033] After the clamp in the present disclosure is lifted and the lifted steel column is docked with the welded steel column, the bidirectional motor 441 is started so that the bidirectional motor 441 can drive the driving wheel 442 to rotate, and the driving wheel 442 fits the radial inner wall of the axial groove 3, so that the driving wheel 442 can roll on the radial inner wall of the axial groove 3, and then the driving wheel 442 drives the arc block 4 in the axial groove 3 to move, so that the welding gun can move circumferentially and weld the end of the lifted steel column.
[0034] A cleaning surface 45 is fixedly provided on the upper inner surface of the arc block 4. When the motor 441 and the drive wheel 442 drive the arc block 4 and the welding gun to move, the cleaning surface 45 simultaneously contacts the circumferential surfaces of the suspended steel column and the welded and fixed steel column. Therefore, before welding with the welding gun, the cleaning surface 45 can clean the circumferential surfaces of the suspended steel column and the welded and fixed steel column, thereby facilitating subsequent welding with the welding gun.
[0035] See also Figure 2 and 3 It can be seen that a brush is provided in the cleaning surface 45, and a protruding wall is provided on the inner surface of the arc block 4 near the welding device 43. A collecting groove 47 is provided on the upper part of the protruding wall, and a collecting wall 48 is detachably installed in the collecting groove 47. In the embodiment of the present disclosure, the collecting wall 48 is installed along the axial sliding of the upper clamp 1 or the lower clamp 2, and a collecting cavity for accommodating impurities is opened in the collecting wall 48.
[0036] During the circumferential movement of the arc block 4, the brush on the cleaning surface 45 cleans the circumferential surface of the suspended steel column and the welded and fixed steel column. The cleaned impurities fall under the influence of gravity and are collected in the collecting wall 48. After the collection is completed, the collecting wall 48 is regularly disassembled by sliding it axially along the upper clamp 1 or the lower clamp 2 to clean the impurities accumulated in the collecting wall 48.
[0037] See also Figure 5 As can be seen, the collecting wall 48 is provided with a relatively inclined slope 482. Impurities collected by the collecting wall 48 slide along the upper slope 482 to the lower slope 482, and then slide step by step to finally enter the inner wall of the collecting wall 48. The relatively inclined slope 482 can prevent impurities from scattering during the rotation of the collecting wall 48 with the arc block 4, thereby better preserving the impurities for centralized collection.
[0038] The collecting wall 48 is made of plastic, which allows it to contain impurities while being lightweight and easy to disassemble. Axially opposing surfaces of the collecting wall 48 and the collecting tank 47 are respectively fixedly mounted with an N-pole magnet 481 and an S-pole magnet that cooperate with each other to fix the collecting wall 48. The collecting wall 48 can be fixed to the collecting tank 47 by the cooperating N-pole magnet 481 and S-pole magnet. By directly pulling the collecting wall 48, the collecting wall 48 can be separated from the collecting tank 47 and axially slid, thereby allowing the collecting wall 48 to be removed and the impurities accumulated therein to be cleaned.
[0039] The protrusions 46 in the upper and lower clamps 1 and 2 extend in the same circumferential direction, allowing the curved plates and welding guns in the upper and lower clamps 1 and 2 to move synchronously with each other, thereby ensuring complete welding of the steel column ends. It should be noted that the welding gun in the upper clamp 1 welds the steel column from the lower clamp 2, and similarly, the welding gun in the lower clamp 2 welds from the upper clamp 1.
[0040] The working process of the embodiment of the present disclosure is as follows: first, the two ends of the upper clamp 1 and the lower clamp 2 are separated and opened by loosening the bolts, and then the upper clamp 1 and the lower clamp 2 are placed on both sides of the steel column respectively, and then the upper clamp 1 and the lower clamp 2 are tightened by bolts, and then the electromagnetic lifter 7 is energized to magnetize the internal iron core of the electromagnetic lifter 7, thereby adsorbing the steel column to complete the fixation of the steel column, and then the clamp and steel column in the embodiment of the present disclosure can be lifted by a gantry crane or a crane.
[0041] After the clamp in the present disclosure is lifted, the extension plate 5 can be close to the fixed steel structure, so that the steel column and the welded steel structure can be stably docked, reducing the error in the docking welding process. After the docking is completed, the telescopic rod 42 drives the welding gun to move axially, so that the welding gun is aligned with the end of the steel column, and then the bidirectional motor 441 is started, so that the bidirectional motor 441 can drive the driving wheel 442 to rotate, and the driving wheel 442 fits the radial inner wall of the axial groove 3, so that the driving wheel 442 can roll on the radial inner wall of the axial groove 3, and then the driving wheel 442 drives the arc block 4 to move in the axial groove 3, so that the welding gun can move circumferentially and weld the end of the lifted steel column.
[0042] While the bidirectional motor 441 drives the arc block 4, the cleaning surface 45 is located in front of the circumferential movement direction of the welding gun. The brush of the cleaning surface 45 cleans the circumferential surface of the suspended steel column and the welded and fixed steel column. The cleaned impurities fall into the collecting wall 48 under the influence of gravity and are collected. After the collection is completed, the collecting wall 48 is directly pulled to separate the N-pole magnet 481 and the S-pole magnet from each other, so that the collecting wall 48 can be separated from the collecting groove 47 and slide axially, and then the collecting wall 48 can be taken out and the impurities accumulated inside can be cleaned, thereby cleaning the impurities accumulated in the collecting wall 48.
