[0002] Compared with cast-in-place structures, bent structures have the advantages of greater bearing capacity and rigidity within their own plane, convenient and quick construction, and less pollution to the environment. With the development of construction engineering, bent structures have increasingly become the structural form of choice for tall and spacious single-story buildings. The bent structure is a building or structure with two rows of prefabricated bent columns at the bottom. The prefabricated bent columns require a safe and reliable lifting tool to complete the installation of the bent columns.

[0003] The existing frame column lifting tools are complex and bulky in structure, and have poor maneuverability. The frame columns need to be precisely adjusted in verticality and horizontal position during installation. The large and complex lifting equipment is not conducive to the deviation correction of the frame columns, and has high operating requirements for crane drivers. At the same time, it cannot guarantee the personal safety of workers under the frame columns. Therefore, we designed a frame column lifting tool, and the frame column is put on the lifting tool. The lifting wire rope is limited and will not move at will. It can also prevent it from falling off due to force, thereby ensuring stable lifting and safety. Utility Model Content

[0025] Figure 1-4A rack column lifting tool according to an embodiment of the utility model is shown, which includes a lifting main rod 1, a limited collar 2 is fixedly connected to the left end of the surface of the lifting main rod 1, a limited collar 2 is sleeved on the right side of the surface of the lifting main rod 1, a positioning ring 4 is welded on the right side of the limited collar 2 3, the positioning ring 4 and the limited collar 2 3 are sleeved on the surface of the lifting main rod 1, the surfaces of the limited collar 2 3 and the limited collar 1 2 are sleeved with a wire rope body 5, the surfaces of the limited collar 1 2 and the limited collar 2 3 are provided with an annular groove for sleeveing ​​the wire rope body 5, through the setting of the annular groove, the wire rope body 5 is sleeved in the annular groove, and the wire rope body 5 is sleeved in the annular groove. It plays a limiting role, ensuring that the wire rope will not move arbitrarily and will not fall off. A lock hole 6 is opened on the right end of the surface of the lifting main rod 1, and a lock hole 2 7 matched with the lock hole 6 is opened on the positioning ring 4. A positioning slot 9 is opened on the right end of the surface of the lifting main rod 1. The inner cavity of the limiting collar 2 3 and the positioning ring 4 is fixedly connected with a positioning block 10 matched with the positioning slot 9. Through the coordinated use of the positioning slot 9 and the positioning block 10, when the limiting collar 2 3 and the positioning ring 4 are sleeved on the lifting main rod 1, the positioning block 10 is inserted into the inner cavity of the positioning slot 9, which is convenient for the installation of the limiting collar 2 3 and the positioning ring 4. To achieve positioning and prevent the limiting collar 2 3 and the positioning ring 4 from rotating, it is convenient to align the lock hole 1 6 with the lock hole 2 7, and improve the alignment and locking efficiency. A locking assembly 8 is arranged between the lock hole 1 6 and the lock hole 2 7. The locking assembly 8 includes a square column 81. Two symmetrical square grooves 82 are arranged on the square column 81. The inner cavity of the square groove 82 is slidably connected with a Z-shaped rod 84. The opposite sides of the two Z-shaped rods 84 are fixedly connected with a limiting locking pin 85. One end of the limiting locking pin 85 is inserted into the inner cavity of the lock hole 1 6 and the lock hole 2 7. The inner cavity of the square groove 82 is fixedly connected with a guide rod 83. The Z-shaped rod 84 is slidably connected to the surface of the guide rod 83. The surface of the Z-shaped rod 84 is provided with a guide rod 83, and the Z-shaped rod 84 will slide on the surface of the guide rod 83 during the sliding process. On the one hand, it can limit the Z-shaped rod 84 from leaving the inner cavity of the square groove 82, and on the other hand, it improves the stability of the Z-shaped rod 84 when sliding. The inner cavity of the square groove 82 is provided with a spring 86 which is sleeved on the surface of the guide rod 83. The two ends of the spring 86 are respectively fixedly connected to the inner wall of the square groove 82 and the Z-shaped rod 84. A pressure plate 87 is provided on one side of the square column 81. One side of the pressure plate 87 is rotatably connected to two symmetrical diagonal support rods 88 through a rotating shaft. The end of the diagonal support rod 88 away from the pressure plate 87 is rotatably connected to the Z-shaped rod 84 through a rotating shaft.

[0026] Working principle: When the utility model is used, the lifting main rod 1 is passed through the through hole of the rack column, and then the limiting collar 2 3 and the positioning ring 4 are sleeved on the surface of the lifting main rod 1. At this time, the lock hole 1 6 is aligned with the lock hole 2 7, and then the square column 81 is picked up, and the pressure plate 87 is pushed to move toward the square column 81. The two diagonal support rods 88 push the two Z-shaped rods 84 to move in the inner cavity of the square groove 82 in opposite directions, thereby causing the two limiting lock pins 85 to move in opposite directions. At this time, the Z-shaped rod 84 squeezes the spring 86 until the space between the two limiting lock pins 85 is larger than the outer diameter of the positioning ring 4. Then, after the limiting lock pin 85 on the locking assembly 8 is aligned with the lock hole 1 6 and the lock hole 2 7, the force on the pressure plate 87 is cancelled, and the elastic force of the spring 86 makes the Z-shaped rod 84 moves toward the positioning ring 4, so that the limit locking pin 85 is inserted into the inner cavity of the locking hole 1 6 and the locking hole 2 7, so as to fix the limit sleeve 2 3 and the positioning ring 4, and the wire rope body 5 is hung on the inner side of the limit sleeve 1 2 and the limit sleeve 2 3 respectively. The wire rope will not move or fall off at will, thereby ensuring the uniform force of the lifting equipment and thus improving the safety of lifting. After the crane is started, the frame column is lifted to the specified position, the wire rope body 5 on the surface of the limit sleeve 1 2 and the limit sleeve 2 3 is removed, and then the pressure plate 87 is pushed to move toward the square column 81, so that the two limit locking pins 85 move away from the inner cavity of the locking hole 1 6 and the locking hole 2 7, and then the lifting main rod 1 is pulled out from the through hole of the frame column to complete the lifting work.

[0027] To sum up: the frame column lifting tool, through the frame column is sleeved on the surface of the lifting main rod 1, the metal ring inside the limiting collar 2 plays a limiting role, preventing the lifting tool from moving in the horizontal through hole of the frame column and causing uneven force on both ends of the lifting device, the limiting collar 2 3 and the positioning ring 4 are sleeved on the surface of the lifting main rod 1, and then the limiting lock pin 85 on the locking assembly 8 is inserted into the inner cavity of the lock hole 1 6 and the lock hole 2 7 to limit the frame column from detaching from the surface of the lifting main rod 1, and the wire rope is sleeved on the inner side of the limiting collar 2 and the limiting collar 2 3 for lifting, so that the frame column can be sleeved on the lifting tool, the lifting wire rope is limited, will not move at will and prevents it from falling off due to force, thereby ensuring the stability of the lifting and the safety.
