Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a scaffolding for building engineering. Background Technology

[0002] Scaffolding is an indispensable tool in construction sites. Its main purpose is to provide a safe working platform for construction workers to work at heights while ensuring their safety. Specifically, the functions of scaffolding include providing a safe working platform, stacking and transporting building materials, ensuring construction safety, and facilitating construction operations.

[0003] Existing scaffolding used in construction projects typically consists of a support plate and a support frame. Prolonged use may cause the support frame to sway. Furthermore, when workers on the support plate need to change tools, they usually have to either go down to get them or have someone throw them up from below. This process is not only time-consuming but also carries the risk of accidentally hitting workers above. Utility Model Content

[0022] like Figure 2 As shown, two sliding plates 301 are fixedly installed at the bottom of the support plate 3. Each sliding plate 301 has a groove 302 inside. A sliding shaft 15 is slidably connected inside the two grooves 302. A bracket 12 is fixedly connected to both ends of the sliding shaft 15. Two brackets 11 are rotatably connected to the bottom of the support plate 3. A shaft 19 is rotatably connected at the intersection of brackets 11 and brackets 12.

[0026] like Figure 2 As shown, cylinder 23 is electrically connected to switch 6.

[0027] In summary, when using the scaffolding for this construction project, workers first stand on the support plate 3. Then, the workers use switch 6 to control cylinder 23, first pulling the rotating block 22 to move, indirectly pulling the sliding shaft 21 to move on the sliding groove 102. Because one side of the two supports 3 13 is fixedly connected to both ends of the sliding shaft 21, the support plate 3 will rise through the operation of cylinder 23. When the support plate 3 reaches its highest point, the worker presses switch 6 to stop the rise and then begins work. When more people need to work on the support plate 3, the worker on top can pull the rope 901 to lift the support frame 9, then open the extension plate 4. Then, using the cooperation of the support frame 9 and the stop block 401, the extension plate 4... Fixed to one side of the support plate 3, this allows multiple people to stand and work. When a worker needs to change tools, to save time and prevent injury from tools thrown upwards, the worker can turn the hand crank 25. The hand crank 25 drives the worm gear 27 to rotate, which in turn drives the worm wheel 28 to rotate. The worm wheel 28 then drives the rope coiling disc 26 to rotate. At this time, the tools inside the toolbox 8 will rise as the rope 7 winds around the rope coiling disc 26. Because the worm wheel 28 and worm gear 17 have a self-locking function, there is no need to worry about the toolbox 8 falling down. Then, the worker can take out the tools from the toolbox 8 and continue working. The above is the usage process of this device.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
