Description

Technical Field

[0001] This invention relates to the field of steel structure technology, specifically to a pre-positioning structure for steel structure hoisting. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. They are primarily composed of steel beams, steel columns, steel trusses, and other components made of steel sections and plates, and employ rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components are typically connected by welds, bolts, or rivets. Due to their light weight and ease of construction, they are widely used in large factories, stadiums, and high-rise buildings. Steel used in steel structures includes hot-rolled steel sections, cold-formed thin-walled steel sections, thin-walled steel sections, steel pipes, and plates. Commonly used hot-rolled steel sections include angle steel (equal and unequal angle steel), I-beams, channel steel, T-beams, H-beams, and L-beams. When hoisting I-beams, it is usually necessary to tie steel cables to both ends of the I-beam for hoisting. At the same time, when tying the steel cables, the workers also need to measure the I-beam to ensure that the hoisting points at both ends are symmetrical. This makes the steel cable binding hoisting very troublesome and inconvenient for hoisting I-beams. To address this, we propose a pre-positioning structure for steel structure hoisting. Summary of the Invention

[0003] The purpose of this invention is to provide a pre-positioning structure for steel structure hoisting, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a pre-positioning structure for steel structure hoisting, comprising an I-beam and a sliding plate disposed on the I-beam, and further comprising an L-shaped limiting plate, wherein two L-shaped limiting plates are provided and symmetrically distributed on both sides of the sliding plate, and the I-beam is fitted by the cooperation of the L-shaped limiting plate and the sliding plate.

[0005] A reel, the reel being disposed on the sliding plate;

[0006] A rectangular pull cord, one end of which is wound around the spool, and the rectangular pull cord is designed with markings sprayed on it;

[0007] A fixed hook is provided at one end of the rectangular pull rope. The fixed hook is used to hook the end of the I-beam, move the sliding plate, and pull out the rectangular pull rope to display the scale.

[0008] A friction limiting plate, wherein the friction limiting plate is disposed on the sliding plate;

[0009] A driving assembly is disposed on the sliding plate, and the driving assembly is used to drive the friction limiting plate to move and squeeze the I-beam;

[0010] The hook, which is set on the sliding plate, differs from the existing technology. In actual use, one end of the rectangular pull rope is fixed to one end of the I-beam by the fixed hook. Then, the sliding plate slides along the I-beam while the rectangular pull rope is pulled out and the sliding plate movement distance is recorded and determined by the scale. Then, the friction limit plate is used to squeeze the I-beam to fix the sliding plate and the I-beam, thereby achieving the effect of quickly installing the main body of the device. Similarly, the other end of the I-beam is used to fix another main body of the device by the displayed scale. Thus, during hoisting, it is only necessary to connect the hook of the hoisting equipment to the hooks of the two main bodies of the device to easily lift the I-beam. It is convenient, simple and practical to operate.

[0011] After the I-beam is hoisted and installed, workers can pull the rectangular ropes at both ends of the I-beam to deflect the L-shaped limit plate away from the I-beam. This is simple, convenient, and relatively safe.

[0012] Preferably, the sliding plate is provided with a shaft, which passes through the scroll, and the scroll is hollow. A coil spring is provided inside the scroll.

[0019] Preferably, one end of the L-shaped limiting plate is provided with a shaft six, the shaft six is ​​connected to the sliding plate, and the sliding plate is provided with a shaft seven. A synchronization component is provided between the shaft seven and the shaft six. Rotating the shaft seven and using the synchronization component to drive the shaft six to rotate will cause the L-shaped limiting plate to deflect away from the I-beam.

[0021] Preferably, the auxiliary component includes a movable plate disposed on the shaft seven, and the shaft eight passes through one end of the movable plate. A rotating ring is disposed at one end of the movable plate, and a spring is disposed between the rotating ring and the gear disk two.

A four-slide groove is provided on the sliding plate, and one end of the sliding protrusion is located in the four-slide groove to guide and limit the triangular block.

[0025] This invention has at least the following beneficial effects:

[0026] Unlike existing technologies, in actual use, a rectangular pull rope is fixed to one end of an I-beam using a fixed hook. Then, a sliding plate slides along the I-beam while the rectangular pull rope is pulled out and the sliding plate's movement distance is recorded and determined using a scale. Then, a friction limiting plate is used to press the I-beam to fix the sliding plate to the I-beam, thus achieving the effect of quickly installing the main body of the device. Similarly, the other end of the I-beam is used to fix another main body of the device using the displayed scale. Therefore, during hoisting, it is only necessary to connect the hook of the hoisting equipment to the hooks of the two main bodies of the device to easily lift the I-beam, which is convenient, simple and practical.

[0027] After the I-beam is hoisted and installed, workers can pull the rectangular ropes at both ends of the I-beam to deflect the L-shaped limit plate away from the I-beam. This is simple, convenient, and relatively safe. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example 1

[0040] Please see Figure 1-8 The present invention provides a technical solution: a pre-positioning structure for steel structure hoisting, including an I-beam 1 and a sliding plate 11 disposed on the I-beam 1, and also including an L-shaped limiting plate 2. The L-shaped limiting plate 2 is provided in two pieces and symmetrically distributed on both sides of the sliding plate 11. The I-beam 1 is fitted by the L-shaped limiting plate 2 and the sliding plate 11, thereby connecting the sliding plate 11 to the I-beam 1 by utilizing the inherent characteristics of the I-beam 1.

[0041] Scroll 3 is mounted on sliding plate 11;

[0042] A rectangular pull rope 4, one end of which is wound around the reel 3, and the rectangular pull rope 4 is designed with markings sprayed on it;

[0043] Fixed hook 5 is set at one end of rectangular pull rope 4. The fixed hook 5 is used to hook the end of I-beam 1, move sliding plate 11, and pull out rectangular pull rope 4 to display scale.

[0044] Friction limiting plate 6 is disposed on sliding plate 11;

[0045] Drive component 7 is mounted on sliding plate 11. Drive component 7 drives friction limiting plate 6 to move and compress I-beam 1.

[0046] The hook 8 is fixedly connected to the sliding plate 11. The fixed hook 5 fixes one end of the rectangular pull rope 4 to one end of the I-beam 1. Then, the sliding plate 11 slides along the I-beam 1 while the rectangular pull rope 4 is pulled out. The movement distance of the sliding plate 11 is recorded and determined using the scale. Then, the friction limit plate 6 is used to limit and fix the sliding plate 11 to the I-beam 1, thereby achieving the effect of quickly installing the main body of the device. Similarly, the other end of the I-beam 1 is fixed to the main body of the device using the displayed scale. Therefore, during hoisting, it is only necessary to connect the hook of the hoisting equipment to the hook 8 to easily lift the I-beam 1. It is convenient, simple and practical to operate.

[0047] A shaft 12 is fixedly connected to the sliding plate 11. The shaft 12 passes through the scroll 3 and is rotatably connected to it through a bearing. The scroll 3 is hollow and has a coil spring 13 inside. The two ends of the coil spring 13 are fixedly connected to the inner wall of the scroll 3 and the shaft 12, respectively. Pulling the rectangular pull rope 4 drives the scroll 3 to rotate. At the same time, the coil spring 13 is compressed under force to provide its self-recovery ability. Thus, after the rectangular pull rope 4 is released, the coil spring 13 can be used to reset and automatically retract the scroll.

[0048] The drive assembly 7 includes a sliding column 71 fixedly connected to both ends of the friction limiting plate 6. One end of the sliding column 71 slides through the sliding plate 11 and is fixedly connected to a force plate 72. A second shaft 73 is rotatably connected to the sliding plate 11 via a bearing. A first screw 74 is fixedly connected to the second shaft 73. One end of the first screw 74 passes through the force plate 72 and is threadedly connected to it. A turntable 75 is fixedly connected to one end of the second shaft 73. By rotating the turntable 75, the second shaft 73 is rotated, which in turn rotates the first screw 74, thereby moving the force plate 72, which in turn moves the sliding column 71. This causes the friction limiting plate 6 to press against the I-beam 1 to fix the sliding plate 11 and the I-beam 1, thereby improving the stability of the device.

[0049] A mounting frame 76 is slidably connected to one side of the sliding plate 11. A roller 77 that contacts the I-beam 1 is rotatably connected inside the mounting frame 76 via a rotating shaft. This reduces friction between the sliding plate 11 and the I-beam 1 when the sliding plate 11 is moved, thus facilitating the rapid movement of the main body of the device. A linkage component 78 is provided between the mounting frame 76 and the friction limiting plate 6. The friction limiting plate 6 is moved down and the linkage component 78 drives the roller 77 to move up and disengage from the I-beam 1, thereby improving the stability of the main body of the device when it is fixed.

[0050] The linkage component 78 includes a third shaft 79 fixedly connected to the mounting frame 76, a fourth shaft 81 rotatably connected to the sliding plate 11 via a rotating shaft, a connecting plate fixedly connected to the friction limiting plate 6, a fifth shaft 82 fixedly connected to the connecting plate, and a deflection plate 83 rotatably connected to the fourth shaft 81 via a bearing. Both ends of the deflection plate 83 are provided with a sliding groove. The third shaft 79 and the fifth shaft 82 pass through the two sliding grooves and are slidably connected to their inner walls. Moving the friction limiting plate 6 drives the deflection plate 83 to rotate, thereby driving the fourth shaft 81 to move, and in turn driving the mounting frame 76 to move.

[0051] The fixed hook 5 includes a rectangular plate 51 fixedly connected to one end of the rectangular pull rope 4. A movable plate 52 is provided at one end of the rectangular plate 51. A second groove 53 is provided on the movable plate 52. A guide plate 54 is fixedly connected to one end of the rectangular plate 51. The guide plate 54 slides through the second groove 53 and moves the movable plate 52 away from the I-beam 1.

[0052] A spring piece 55 is fixedly connected to the rectangular plate 51, and one end of the spring piece 55 contacts and abuts against the movable plate 52. When the movable plate 52 is moved, the spring piece 55 is deformed by force to provide its self-recovery capability.

[0053] A rectangular magnet 56 is provided on one side of the rectangular plate 51. The rectangular magnet 56 is used to hold the I-beam 1. After the measurement task of the rectangular pull rope 4 is completed, the rectangular plate 51 at its end can be picked up and then the fixing hook 5 is fixed to the top surface of the I-beam 1 by the rectangular magnet 56. This ensures that the movable plate 52 does not interfere with the docking operation at the end of the I-beam 1 during installation.

[0054] One end of the L-shaped limiting plate 2 is fixedly connected to a shaft 57. The shaft 57 is rotatably connected to the sliding plate 11 via a bearing. The sliding plate 11 is rotatably connected to a shaft 58 via a bearing. A synchronization component 59 is provided between the shaft 58 and the shaft 57. Rotating the shaft 58 and using the synchronization component 59 to drive the shaft 57 to rotate causes the L-shaped limiting plate 2 to deflect away from the I-beam 1. Thus, when the I-beam 1 is lifted and installed, the L-shaped limiting plate 2 can be deflected to open, allowing the device to quickly unlock and detach from the I-beam 1. This is relatively simple and convenient.

[0055] A gear disc 61 is fixedly connected to shaft 7 58, and a shaft 8 62 is fixedly connected to sliding plate 11. A gear disc 63, which meshes with gear disc 61, is slidably connected to shaft 8 62, and gear disc 63 can rotate relative to shaft 8 62. A hollow gear disc 64 is fixedly connected to one end of the roller 3, and an auxiliary component 65 is provided between the force plate 72 and gear disc 63. Moving the force plate 72 causes gear disc 63 to move and mesh with hollow gear disc 64. Pulling the rectangular pull rope 4 then causes shaft 7 58 to rotate, thus enabling the operation of the machine. When personnel fix the sliding plate 11, they use the auxiliary component 65 to make the gear plate 2 63 mesh with the hollow gear plate 3 64. After the hoisting and installation of the I-beam 1 is completed, the personnel can pull the rectangular pull rope 4 at both ends of the I-beam 1, thereby driving the roller 3 to rotate, which in turn drives the hollow gear plate 3 64 to rotate, which in turn drives the gear plate 2 63 to rotate, which in turn drives the gear plate 1 61 to rotate, which in turn drives the shaft 7 58 to rotate, thereby causing the L-shaped limit plate 2 to deflect and disengage from the I-beam 1. This is simple, convenient and relatively safe.

[0056] The auxiliary component 65 includes a movable plate 66 that slides with shaft 7 58, and shaft 8 62 slides through one end of the movable plate 66. A rotating ring is rotatably connected to one end of the movable plate 66. Shaft 8 62 slides through the rotating ring, and a spring 67 is fixedly connected between the rotating ring and the gear disk 2 63. The movable plate 66 pushes the gear disk 2 63 to move by means of the spring 67.

[0057] A triangular block 68 is fixedly connected to one end of the movable plate 66. A sliding protrusion 69 is fixedly connected to one side of the triangular block 68. A sliding groove 91 is provided on the sliding plate 11. One end of the sliding protrusion 69 is located in the sliding groove 91 and is slidably connected to its inner wall to guide and limit the triangular block 68. A triangular block 68 is also fixedly connected to the force plate 72. The force plate 72 is moved and one triangular block 68 pushes the other triangular block 68 to move, thereby driving the movable plate 66 to move.

[0058] The synchronization component 59 includes a rotating plate 92 fixedly connected to shaft 6 57, and a sleeve 93 slidably connected to the sliding plate 11. A connecting rod 94 is fixedly connected to one end of the sleeve 93, and a shaft 95 is fixedly connected to one end of the connecting rod 94. A sliding groove 5 96 is provided on the rotating plate 92. One end of shaft 95 passes through the sliding groove 5 96 and is slidably connected to its inner wall. A screw 2 97 is fixedly connected to shaft 7 58. One end of screw 2 97 is located inside the sleeve 93 and is threadedly connected to its inner wall. Rotating shaft 7 58 drives screw 2 97 to rotate, thereby driving sleeve 93 to move, which in turn drives rotating plate 92 to rotate, thereby driving shaft 6 57 to rotate.

[0059] During the normal operation of the pre-positioning structure for steel structure hoisting, one end of the rectangular pull rope 4 is fixed to one end of the I-beam 1 by the fixed hook 5. Then, the sliding plate 11 slides along the I-beam 1 while pulling out the rectangular pull rope 4 and recording and determining the movement distance of the sliding plate 11 using the scale. Then, the turntable 75 is rotated to drive the shaft 73 to rotate, which in turn drives the screw 74 to rotate, thereby driving the force plate 72 to move, which in turn drives the sliding column 71 to move, thereby driving the friction limit plate 6 to squeeze the I-beam 1 to fix the sliding plate 11 and the I-beam 1, thus achieving the effect of quickly installing the main body of the device. Similarly, the other end of the I-beam 1 is used to fix another main body of the device using the displayed scale. Thus, during hoisting, it is only necessary to connect the hook of the hoisting equipment to the hooks 8 of the two main bodies of the device to easily lift the I-beam 1, which is convenient, simple and practical.

[0060] After the I-beam 1 is hoisted and installed, workers can pull the rectangular ropes 4 at both ends of the I-beam 1, which will cause the reel 3 to rotate, which in turn will cause the hollow gear disc 3 64 to rotate, which will cause the gear disc 2 63 to rotate, which will cause the gear disc 1 61 to rotate, which will cause the shaft 7 58 to rotate, which will cause the screw 2 97 to rotate, which will cause the sleeve 93 to move, which will cause the rotating plate 92 to rotate, which will cause the shaft 6 57 to rotate, thereby causing the L-shaped limit plate 2 to deflect and disengage from the I-beam 1. This method is simple, convenient, and relatively safe.

[0061] Example 2

[0062] Please see Figure 2 as well as Figure 4-9 The present invention provides a technical solution: a pre-positioning structure for steel structure hoisting, including an I-beam 1 and a sliding plate 11 disposed on the I-beam 1, and also including an L-shaped limiting plate 2. The L-shaped limiting plate 2 is provided in two pieces and symmetrically distributed on both sides of the sliding plate 11. The I-beam 1 is fitted by the L-shaped limiting plate 2 and the sliding plate 11, thereby connecting the sliding plate 11 to the I-beam 1 by utilizing the inherent characteristics of the I-beam 1.

[0063] Scroll 3 is mounted on sliding plate 11;

[0064] A rectangular pull rope 4, one end of which is wound around the reel 3, and the rectangular pull rope 4 is designed with markings sprayed on it;

[0065] Fixed hook 5 is set at one end of rectangular pull rope 4. The fixed hook 5 is used to hook the end of I-beam 1, move sliding plate 11, and pull out rectangular pull rope 4 to display scale.

[0066] Friction limiting plate 6 is disposed on sliding plate 11;

[0067] Drive component 7 is mounted on sliding plate 11. Drive component 7 drives friction limiting plate 6 to move and compress I-beam 1.

[0068] The hook 8 is fixedly connected to the sliding plate 11. The fixed hook 5 fixes one end of the rectangular pull rope 4 to one end of the I-beam 1. Then, the sliding plate 11 slides along the I-beam 1 while the rectangular pull rope 4 is pulled out. The movement distance of the sliding plate 11 is recorded and determined using the scale. Then, the friction limit plate 6 is used to limit and fix the sliding plate 11 to the I-beam 1, thereby achieving the effect of quickly installing the main body of the device. Similarly, the other end of the I-beam 1 is fixed to the main body of the device using the displayed scale. Therefore, during hoisting, it is only necessary to connect the hook of the hoisting equipment to the hook 8 to easily lift the I-beam 1. It is convenient, simple and practical to operate.

[0069] A shaft 12 is fixedly connected to the sliding plate 11. The shaft 12 passes through the scroll 3 and is rotatably connected to it through a bearing. The scroll 3 is hollow and has a coil spring 13 inside. The two ends of the coil spring 13 are fixedly connected to the inner wall of the scroll 3 and the shaft 12, respectively. Pulling the rectangular pull rope 4 drives the scroll 3 to rotate. At the same time, the coil spring 13 is compressed under force to provide its self-recovery ability. Thus, after the rectangular pull rope 4 is released, the coil spring 13 can be used to reset and automatically retract the scroll.

[0070] The drive assembly 7 includes a sliding column 71 fixedly connected to both ends of the friction limiting plate 6. One end of the sliding column 71 slides through the sliding plate 11 and is fixedly connected to a force plate 72. A second shaft 73 is rotatably connected to the sliding plate 11 via a bearing. A first screw 74 is fixedly connected to the second shaft 73. One end of the first screw 74 passes through the force plate 72 and is threadedly connected to it. A turntable 75 is fixedly connected to one end of the second shaft 73. By rotating the turntable 75, the second shaft 73 is rotated, which in turn rotates the first screw 74, thereby moving the force plate 72, which in turn moves the sliding column 71. This causes the friction limiting plate 6 to press against the I-beam 1 to fix the sliding plate 11 and the I-beam 1, thereby improving the stability of the device.

[0071] A mounting frame 76 is slidably connected to one side of the sliding plate 11. A roller 77 that contacts the I-beam 1 is rotatably connected inside the mounting frame 76 via a rotating shaft. This reduces friction between the sliding plate 11 and the I-beam 1 when the sliding plate 11 is moved, thus facilitating the rapid movement of the main body of the device. A linkage component 78 is provided between the mounting frame 76 and the friction limiting plate 6. The friction limiting plate 6 is moved down and the linkage component 78 drives the roller 77 to move up and disengage from the I-beam 1, thereby improving the stability of the main body of the device when it is fixed.

[0072] The linkage component 78 includes a third shaft 79 fixedly connected to the mounting frame 76, a fourth shaft 81 rotatably connected to the sliding plate 11 via a rotating shaft, a connecting plate fixedly connected to the friction limiting plate 6, a fifth shaft 82 fixedly connected to the connecting plate, and a deflection plate 83 rotatably connected to the fourth shaft 81 via a bearing. Both ends of the deflection plate 83 are provided with a sliding groove. The third shaft 79 and the fifth shaft 82 pass through the two sliding grooves and are slidably connected to their inner walls. Moving the friction limiting plate 6 drives the deflection plate 83 to rotate, thereby driving the fourth shaft 81 to move, and in turn driving the mounting frame 76 to move.

[0073] The fixed hook 5 includes a rectangular plate 51 fixedly connected to one end of the rectangular pull rope 4. A movable plate 52 is provided at one end of the rectangular plate 51. A second groove 53 is provided on the movable plate 52. A guide plate 54 is fixedly connected to one end of the rectangular plate 51. The guide plate 54 slides through the second groove 53 and moves the movable plate 52 away from the I-beam 1.

[0074] A spring piece 55 is fixedly connected to the rectangular plate 51, and one end of the spring piece 55 contacts and abuts against the movable plate 52. When the movable plate 52 is moved, the spring piece 55 is deformed by force to provide its self-recovery capability.

[0075] A rectangular magnet 56 is provided on one side of the rectangular plate 51. The rectangular magnet 56 is used to hold the I-beam 1. After the measurement task of the rectangular pull rope 4 is completed, the rectangular plate 51 at its end can be picked up and then the fixing hook 5 is fixed to the top surface of the I-beam 1 by the rectangular magnet 56. This ensures that the movable plate 52 does not interfere with the docking operation at the end of the I-beam 1 during installation.

[0076] One end of the L-shaped limiting plate 2 is fixedly connected to a shaft 57. The shaft 57 is rotatably connected to the sliding plate 11 via a bearing. The sliding plate 11 is rotatably connected to a shaft 58 via a bearing. A synchronization component 59 is provided between the shaft 58 and the shaft 57. Rotating the shaft 58 and using the synchronization component 59 to drive the shaft 57 to rotate causes the L-shaped limiting plate 2 to deflect away from the I-beam 1. Thus, when the I-beam 1 is lifted and installed, the L-shaped limiting plate 2 can be deflected to open, allowing the device to quickly unlock and detach from the I-beam 1. This is relatively simple and convenient.

[0077] A gear disc 61 is fixedly connected to shaft 7 58, and a shaft 8 62 is fixedly connected to sliding plate 11. A gear disc 63, which meshes with gear disc 61, is slidably connected to shaft 8 62, and gear disc 63 can rotate relative to shaft 8 62. A hollow gear disc 64 is fixedly connected to one end of the roller 3, and an auxiliary component 65 is provided between the force plate 72 and gear disc 63. Moving the force plate 72 causes gear disc 63 to move and mesh with hollow gear disc 64. Pulling the rectangular pull rope 4 then causes shaft 7 58 to rotate, thus enabling the operation of the machine. When personnel fix the sliding plate 11, they use the auxiliary component 65 to make the gear plate 2 63 mesh with the hollow gear plate 3 64. After the hoisting and installation of the I-beam 1 is completed, the personnel can pull the rectangular pull rope 4 at both ends of the I-beam 1, thereby driving the roller 3 to rotate, which in turn drives the hollow gear plate 3 64 to rotate, which in turn drives the gear plate 2 63 to rotate, which in turn drives the gear plate 1 61 to rotate, which in turn drives the shaft 7 58 to rotate, thereby causing the L-shaped limit plate 2 to deflect and disengage from the I-beam 1. This is simple, convenient and relatively safe.

[0078] The auxiliary component 65 includes a movable plate 66 that slides with shaft 7 58, and shaft 8 62 slides through one end of the movable plate 66. A rotating ring is rotatably connected to one end of the movable plate 66. Shaft 8 62 slides through the rotating ring, and a spring 67 is fixedly connected between the rotating ring and the gear disk 2 63. The movable plate 66 pushes the gear disk 2 63 to move by means of the spring 67.

[0079] A triangular block 68 is fixedly connected to one end of the movable plate 66. A sliding protrusion 69 is fixedly connected to one side of the triangular block 68. A sliding groove 91 is provided on the sliding plate 11. One end of the sliding protrusion 69 is located in the sliding groove 91 and is slidably connected to its inner wall to guide and limit the triangular block 68. A triangular block 68 is also fixedly connected to the force plate 72. The force plate 72 is moved and one triangular block 68 pushes the other triangular block 68 to move, thereby driving the movable plate 66 to move.

[0080] The synchronization component 59 includes a worm gear 98 fixedly connected to shaft 6 57, and a worm 99 meshing with the worm gear 98 is fixedly connected to shaft 7 58. Rotating shaft 7 58 causes the worm 99 to rotate, which in turn causes the worm gear 98 to rotate, thereby causing shaft 6 57 to rotate.

[0081] During the normal operation of the pre-positioning structure for steel structure hoisting, one end of the rectangular pull rope 4 is fixed to one end of the I-beam 1 by the fixed hook 5. Then, the sliding plate 11 slides along the I-beam 1 while pulling out the rectangular pull rope 4 and recording and determining the movement distance of the sliding plate 11 using the scale. Then, the turntable 75 is rotated to drive the shaft 73 to rotate, which in turn drives the screw 74 to rotate, thereby driving the force plate 72 to move, which in turn drives the sliding column 71 to move, thereby driving the friction limit plate 6 to squeeze the I-beam 1 to fix the sliding plate 11 and the I-beam 1, thus achieving the effect of quickly installing the main body of the device. Similarly, the other end of the I-beam 1 is used to fix another main body of the device using the displayed scale. Thus, during hoisting, it is only necessary to connect the hook of the hoisting equipment to the hooks 8 of the two main bodies of the device to easily lift the I-beam 1, which is convenient, simple and practical.

[0082] After the I-beam 1 is hoisted and installed, workers can pull the rectangular ropes 4 at both ends of the I-beam 1, which will drive the reel 3 to rotate, which in turn will drive the hollow gear disc 3 64 to rotate, which will drive the gear disc 2 63 to rotate, which will drive the gear disc 1 61 to rotate, which will drive the shaft 7 58 to rotate, which will drive the worm gear 99 to rotate, which will drive the worm wheel 98 to rotate, which will drive the shaft 6 57 to rotate, thereby causing the L-shaped limit plate 2 to deflect and detach from the I-beam 1. This method is simple, convenient, and relatively safe.
