Description

Technical Field

[0001] This utility model relates to a mobile device, specifically a mobile device for easy disassembly of light steel structure scaffolding, belonging to the field of scaffolding technology. Background Technology

[0002] The primary function and role of scaffolding is to provide construction workers with a stable and safe working platform, enabling them to perform construction operations at different heights and locations, such as bricklaying, plastering, steel structure building construction, door and window installation, and billboard installation. By erecting scaffolding, construction workers can be isolated from the ground or other dangerous areas, reducing safety risks during construction. It also helps construction workers maintain their balance and stability when working at heights, thereby improving construction efficiency. Scaffolding can be flexibly erected and adjusted according to construction needs, making it easier for construction workers to perform construction operations and improving efficiency. Scaffolding can also be used for stacking building materials. As a temporary support structure for buildings, scaffolding ensures the stability of buildings and the safety of construction workers.

[0003] To facilitate relocation, most existing scaffolding systems are equipped with casters at the bottom. These casters are used to move the scaffolding, and after it's moved to the designated location, the casters are locked to maintain stability. While this structure allows for relocation, the small contact area between the casters and the ground means the scaffolding may sway when under load or when workers are moving up or down. In severe cases, this could lead to collapse, indicating insufficient stability and posing a safety hazard. Therefore, we provide a lightweight steel structure scaffolding system with an easily disassembled moving device to solve these problems. Utility Model Content

[0005] A disassembleable and movable device for light steel scaffolding includes a scaffolding body and a support frame. Two symmetrical sliding tracks are installed at the bottom of the support frame. Support plates are connected to the outer surfaces of the two tracks. Two symmetrical support shafts are connected to the inner walls of each track. A swing frame is rotatably connected to the outer surfaces of each support shaft. A roller is rotatably connected to one end of each swing frame, and a groove is formed at the other end. A threaded seat is slidably connected to the inner wall of the groove, and a positive and negative threaded rod is threaded to the inner wall of the threaded seat. Legs are connected to the upper surface of the support frame, and the end of the scaffolding body is located inside the legs. A locking mechanism is provided inside the legs.

[0022] The present invention will now be further described with reference to the accompanying drawings.

[0023] Please see Figures 1-6 A mobile device for easy disassembly of a light steel structure scaffold includes a scaffold body 1 and a support 2. Two slides 3 are installed under the support 2 and are symmetrical to each other. Support plates 4 are connected to the outer surfaces of the two slides 3. The support 2 provides support for the components to be mounted, and the support plates 4 increase the contact area between the slides 3 and the ground, thereby improving the stability of the slides 3.

[0024] The inner walls of the two slides 3 are each connected to two support shafts 5, and the two support shafts 5 are symmetrical. The outer surfaces of the two support shafts 5 are rotatably connected to swing frames 6. One end of the swing frame 6 is rotatably connected to a roller 7. The support shafts 5 provide support for the swing frame 6 to maintain the stability of the swing frame 6. The swing arm contacts the ground through the roller 7, which facilitates the movement of the scaffold body 1.

[0025] The other end of the swing frame 6 is provided with a groove 8. The inner wall of the groove 8 is slidably connected to a threaded seat 9. The inner wall of the threaded seat 9 is threadedly connected to a positive and negative screw rod 10. The upper surface of the support 2 is connected to a support leg 11. The end of the scaffold body 1 is located inside the support leg 11. The positive and negative screw rod 10 provides a pushing force to push the threaded seat 9 to move. While the threaded seat 9 moves, it pushes the swing frame 6 to swing through the groove 8. The swing frame 6 swings into and out of the slide rail 3. After the swing frame 6 enters the slide rail 3, the roller 7 is hidden inside. When the swing frame 6 swings, an angle difference will be generated between it and the positive and negative screw rod 10. The groove 8 compensates for the angle difference between the threaded seat 9 and the swing frame 6.

[0026] There are four support legs 11, and the four support legs 11 are located at the four corners of the support 2. The support legs 11 provide support for the scaffold body 1 and maintain the stability of the scaffold body 1.

[0027] A locking mechanism 12 is provided inside the outrigger 11 to maintain stability when the scaffold body 1 is connected to the outrigger 11. The locking mechanism 12 includes a locking screw 1201, the outer surface of which is threaded to the inner wall of the outrigger 11. One end of the locking screw 1201 inside the outrigger 11 is connected to an arc-shaped clamp 1202. One side of the arc-shaped clamp 1202 is slidably connected to the inner wall of the outrigger 11, and the other side is in contact with the outer surface of the scaffold body 1. The other end of the locking screw 1201 outside the outrigger 11 is connected to a handwheel 1203. Rotation of the locking screw 1201 generates... The driving force provides power for the movement of the arc-shaped clamp 1202. The arc-shaped clamp 1202 contacts and disengages from the scaffold body 1 through its movement. When the arc-shaped clamp 1202 contacts the scaffold body 1, it provides resistance to the scaffold body 1, restricts the movement of the scaffold body 1, and maintains the stability of the scaffold body 1. After the arc-shaped clamp 1202 disengages from the scaffold body 1, it releases the positioning restriction on the scaffold body 1, and the handwheel 1203 facilitates the rotation of the locking screw 1201 by hand.

[0028] The inner top wall of the slide rail 3 is connected to the lug seat 13. The inner wall of the lug seat 13 is rotatably connected to the outer surface of the positive and negative lead screw 10. The lug seat 13 provides support for the positive and negative lead screw 10 and maintains the stability of the positive and negative lead screw 10.

[0029] A base 14 is connected to the lower surface of the bracket 2. A rotating shaft 15 is rotatably connected to one side of the base 14. A first chain tooth 16 is connected to the outer surface of the rotating shaft 15. A crank 17 is installed at the end of the rotating shaft 15 away from the base 14. The crank 17 facilitates the rotation of the rotating shaft 15. When the rotating shaft 15 rotates, it drives the first chain tooth 16 to rotate. A second chain tooth 18 is connected to the end of the positive and negative lead screw 10 located outside the slide rail 3. The positive and negative lead screw 10 receives the power of the first chain tooth 16 through the second chain tooth 18. The first chain tooth 16 transmits the power to the second chain tooth 18 through the toothed chain 19, thereby driving the second chain tooth 18 to rotate. The toothed chain 19 is sleeved on the outside of the first chain tooth 16 and the second chain tooth 18, and the first chain tooth 16 and the second chain tooth 18 are connected by the toothed chain 19. The two positive and negative lead screws 10 rotate synchronously through the first chain tooth 16 and the second chain tooth 18.

[0030] The side of the support 2 is connected to a rotating seat 20, and the inner wall of the rotating seat 20 is rotatably connected to a handle 21. The rotating seat 20 provides support for the handle 21, making it easy for the handle 21 to rotate. The handle 21 can be rotated to adjust the angle, making it easy for the user to use it at a suitable angle. The handle 21 can be used to move the support 2 and the scaffold body 1 to different positions. After the handle 21 is used, it can be rotated to reset it.

[0031] In use, the scaffold body 1 is first inserted into the support leg 11. Then, the locking screw 1201 is rotated by the handwheel 1203. After the locking screw 1201 rotates, it pushes the arc-shaped clamp 1202 to tightly contact the scaffold body 1, restricting the movement of the scaffold body 1 and maintaining its stability. When the scaffold body 1 needs to move, the rotating shaft 15 is rotated by the crank handle 17. After the rotating shaft 15 rotates, it drives the first chain tooth 16 to rotate simultaneously. At the same time, the first chain tooth 16 drives the second chain tooth 18 to rotate through the toothed chain 19. After the second chain tooth 18 rotates, The positive and negative lead screws 10 rotate simultaneously, which pushes the threaded seat 9 to move. After the threaded seat 9 moves, it pushes the swing frame 6 to swing. After the swing frame 6 swings, the roller 7 contacts the ground. Then, the moving device is pulled by the handle 21 to move to a new position. The moving device moves to a new position at the same time as the scaffold body 1. After the scaffold body 1 moves to the designated position, the operation is reversed to swing the roller 7 into the slide rail 3, so that the sliding and supporting foot plate 4 contacts the ground, providing support for the scaffold body 1 and maintaining the stability of the scaffold body 1.
