DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-2 In this embodiment, an assembled steel structure crossbeam includes two columns 1, and movable holes are provided on opposite sides of the two columns 1, and the movable holes are adapted to the moving blocks 4. The inner top wall of the column 1 is fixed with a lifting assembly fixed to the inner bottom wall of the column 1 and extending to the outside of the column 1. A mounting seat 5 is fixed on the opposite side of the two lifting assemblies. A rotating groove is provided on the inner bottom wall of the mounting seat 5, and the rotating groove is adapted to the roller 6. The lifting assembly is used to adjust the height of the mounting seat 5. The inner bottom wall of the mounting seat 5 is rotatably connected with the roller 6, and the top of the roller 6 is movably in contact with the crossbeam 7. The crossbeam 7 is H-shaped, and a slot is provided on the back of the crossbeam 7, which is adapted to the plug block 807. Through the connection between the plug block 807 and the slot, the fixing mechanism 8 can fix the crossbeam 7 on the mounting seat 5, and the rear side wall of the inner cavity of the mounting seat 5 is fixed with a fixing mechanism 8 extending to the rear side of the mounting seat 5. The fixing mechanism 8 is used to fix the crossbeam 7 to the mounting seat 5.

[0022] In this embodiment, the lifting assembly includes a motor 2 fixed to the inner top wall of the column 1, the output shaft of the motor 2 is fixed with a first threaded rod 3 fixed to the inner bottom wall of the column 1, and the bottom of the first threaded rod 3 is fixed with a bearing fixed to the inner bottom wall of the column 1. Through the setting of the bearing, the first threaded rod 3 is more stable when rotating, thereby improving the stability of the operation of the lifting assembly. The outer surface of the first threaded rod 3 is threadedly connected with a moving block 4 that penetrates to the outside of the column 1 and is fixed to the mounting seat 5. Through the setting of the lifting assembly, the height of the mounting seat 5 can be adjusted, and personnel do not need to perform high-altitude operations when installing the crossbeam 7, thereby improving the safety of the staff.

[0023] It should be noted that the mounting seat 5 is moved to the bottom of the column 1, the beam 7 is placed on the roller 6, the beam 7 is pushed so that the beam 7 is connected to the fixing mechanism 8, and then the fixing mechanism 8 is rotated so that the beam 7 can be quickly fixed on the mounting seat 5, and the lifting component is started. Through the operation of the lifting component, the mounting seat 5 will be driven to rise, so that the mounting seat 5 can drive the beam 7 to rise, thereby achieving the purpose of quickly installing the beam 7, reducing the difficulty of installation, and improving the installation efficiency.

[0024] See also Figure 3The fixing mechanism 8 in this embodiment includes a connecting block 801 fixed to the rear side wall of the inner cavity of the mounting seat 5, a rotating rod 802 penetrating into the interior of the connecting block 801 is fixed to the rear side of the connecting block 801, an adjusting disk 803 is fixed to the back of the rotating rod 802, and an anti-skid groove is provided on the outer surface of the adjusting disk 803. The anti-skid groove can improve the friction between the hand and the adjusting disk 803 to prevent slipping and falling out of the hand when the adjusting disk 803 is rotated, and a fixing component for fixing the crossbeam 7 is fixed to the front of the rotating rod 802, and positioning plates 808 are fixed on the left and right sides of the fixing component, and slide rails compatible with the slider are fixed on the opposite sides of the two positioning plates 808. Through the setting of the slider and the slide rail, the plug-in block 807 can be limited to prevent the plug-in block 807 from rotating synchronously with the second threaded rod 806, thereby improving the stability of the operation of the fixing mechanism 8.

[0025] In this embodiment, the fixing assembly includes a driving gear 804 fixed to the front side of the rotating rod 802, and driven gears 805 are meshed above and below the driving gear 804. Second threaded rods 806 are fixed to the opposite sides of the two driven gears 805. The outer surface of the second threaded rod 806 is threadedly connected to an insert block 807 that penetrates through the outside of the connecting block 801 and is movably connected to the positioning plate 808. Slide blocks are fixed to the left and right sides of the insert block 807. Through the arrangement of the fixing assembly, welding technology is not required for the installation of the beam 7, thereby improving the installation efficiency of the beam 7.

[0026] It should be noted that by rotating the adjusting disk 803, the rotating rod 802 rotates, and the rotation of the rotating rod 802 drives the driving gear 804 to rotate, so that the driven gear 805 meshing with the driving gear 804 rotates, and the rotation of the driven gear 805 drives the second threaded rod 806 to rotate, so that the second threaded rod 806 drives the plug block 807 to move and plug the crossbeam 7, thereby achieving the purpose of quick installation.

[0027] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0028] The working principle of the above embodiment is:

[0029] When in use, the mounting seat 5 is moved to the bottom by the lifting assembly, the crossbeam 7 is placed on the roller 6, and the crossbeam 7 is pushed so that the back side of the crossbeam 7 is connected to the connecting block 801, and then the adjusting disk 803 is rotated to rotate the rotating rod 802. The rotation of the rotating rod 802 will drive the driving gear 804 to rotate, so that the driven gear 805 meshing with the driving gear 804 is rotated, thereby driving the second threaded rod 806 to rotate, and the rotation of the second threaded rod 806 makes the plug block 807 movably connected to the positioning plate 808 move and connect to the slot on the crossbeam 7, thereby completing the installation of the crossbeam 7, and then the operation of the motor 2 makes the first threaded rod 3 rotate, and the rotation of the first threaded rod 3 will drive the moving block 4 to rise, so that the mounting seat 5 fixed to the moving block 4 can drive the crossbeam 7 to rise, thereby realizing the purpose of quickly installing the crossbeam 7, reducing the difficulty of installation, and improving the efficiency of installation.
