Description

Technical Field

[0001] This utility model relates to the field of scaffolding technology, and in particular to a multifunctional scaffolding. Background Technology

[0002] In the construction industry, scaffolding is an important auxiliary construction equipment, and its performance and function directly affect the project progress, construction safety and work efficiency.

[0003] Currently, existing scaffolding lacks sunshade functionality. During outdoor construction, prolonged exposure to sunlight poses a significant risk of heatstroke and sunburn to workers, leading to discomfort and even safety accidents, thus impacting work performance and construction efficiency. Therefore, to better implement outdoor construction safety measures, promote technological advancements in the industry, and enhance core technological competitiveness, this application proposes a novel implementation scheme for multi-functional scaffolding that differs from existing technologies. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of existing scaffolds lacking sunshade function, and to propose a multifunctional scaffold.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multifunctional scaffold includes a scaffold frame. A standing board is fixed to the top of the scaffold frame. Two mounting columns are fixedly connected to the top of the standing board. A winding drum is rotatably mounted between the two mounting columns via an interlocking bearing. A sunshade cloth is wrapped around the outer wall of the winding drum. A support frame is fixedly connected to one side of each mounting column. A first mounting plate is fixedly connected to one side of each mounting column. A lead screw is rotatably mounted between the first mounting plate and the support frame via an interlocking bearing. A connecting rod is threaded onto the outer wall of the lead screw. A second bevel gear is keyed to one end of the lead screw. A sliding rod is fixedly connected between the mounting column and the support frame. The other end of the connecting rod is slidably sleeved with the sliding rod. Both ends of the side are rotatably connected to a second rotating rod via a rotating shaft. The other end of the second rotating rod is rotatably connected to a first rotating rod via a rotating shaft. The top of the sunshade cloth, connecting rod, second rotating rod, and first rotating rod are fixed with bolts. The other end of the first rotating rod is rotatably connected to one side of the mounting column via a rotating shaft. A second mounting plate is fixedly connected to one side of one of the mounting columns. A transmission rod is rotatably mounted on the second mounting plate via an interlocking bearing. A third bevel gear and a fourth bevel gear are keyed to the top of the transmission rod. The third bevel gear meshes with the second bevel gear. A first bevel gear is rotatably connected to one side of one of the mounting columns. The first bevel gear meshes with the fourth bevel gear.

[0007] Furthermore, support legs are fixedly connected to the bottom ends of the four corners of the scaffold frame.

[0008] Furthermore, ladders are fixedly connected to both ends of the scaffold frame.

[0009] Furthermore, a fence is fixedly connected to the top of the standing board.

[0010] Furthermore, a handle is fixedly connected to the bottom end of the transmission rod, and the outer wall of the handle is provided with anti-slip grooves.

[0011] Furthermore, a protective shell is fixedly connected to one side of one of the mounting posts, and the protective shell covers the outside of the first bevel gear, the second bevel gear, the third bevel gear and the fourth bevel gear.

[0012] Furthermore, a bellows is fixedly connected between the protective shell and the connecting rod, and the bellows is sleeved on the outside of the lead screw.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By engaging the first and fourth bevel gears, the winding drum is rotated, thereby unwinding the sunshade cloth. Simultaneously, engaging the third and second bevel gears drives the lead screw to rotate, causing the connecting rod to move outward along the slide rod. This, in turn, causes the first and second rotating rods to rotate to a straight position, thus unfolding the sunshade cloth for sun shading. This effectively blocks direct sunlight and prevents construction workers from suffering from heatstroke and sunburn. This application adds a sunshade function to the scaffolding, thus demonstrating the multi-functionality of the scaffolding.

[0015] 2. The use of support legs increases the support area between the scaffolding and the ground, making it easier to stabilize the scaffolding and preventing it from tipping over. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-4 A multifunctional scaffold includes a scaffold frame 1, with a standing board 4 snapped onto the top of the scaffold frame 1 and fixed to the scaffold frame 1 by bolts. The standing board 4 allows people to stand and operate.

[0023] Two mounting columns 6 are welded to the top of the standing plate 4. A winding drum 7 is rotatably mounted between the two mounting columns 6 via an interlocking bearing. A sunshade cloth 23 is wrapped around the outer wall of the winding drum 7. The sunshade cloth 23 can be made of fiberglass, i.e., fiberglass substrate + PVC coated sunshade cloth, which is fireproof, moistureproof, and blocks ultraviolet rays and solar radiation.

[0024] An inclined support frame is welded to one side of the mounting column 6, and a first mounting plate 12 is welded to one side of the mounting column 6. A lead screw 13 is rotatably mounted between the first mounting plate 12 and the support frame through an interlocking bearing. A connecting rod 10 is threaded to the outer wall of the lead screw 13, and a second bevel gear 14 is keyed to one end of the lead screw 13.

[0025] A sliding rod 15 is welded between the mounting column 6 and the support frame. The other end of the connecting rod 10 is slidably sleeved with the sliding rod 15. Both ends of one side of the connecting rod 10 are rotatably connected to a second rotating rod 9 via a rotating shaft. The other end of the second rotating rod 9 is rotatably connected to a first rotating rod 8 via a rotating shaft. The other end of the first rotating rod 8 is rotatably connected to one side of the mounting column 6 via a rotating shaft. The sunshade cloth 23 is fixed to the top of the connecting rod 10, the second rotating rod 9, and the first rotating rod 8 with bolts.

[0026] A second mounting plate 16 is welded to one side of one of the mounting columns 6. A transmission rod 17 is rotatably mounted on the second mounting plate 16 via an interlocking bearing. A handle 18 is welded to the bottom end of the transmission rod 17. A third bevel gear 19 and a fourth bevel gear 20 are keyed to the top of the transmission rod 17. The third bevel gear 19 meshes with the second bevel gear 14.

[0027] One of the mounting posts 6 is rotatably connected to a first bevel gear 11, which meshes with a fourth bevel gear 20. Turning the handle 18 drives the transmission rod 17 to rotate, which in turn drives the third bevel gear 19 and the fourth bevel gear 20 to rotate. Under the action of the meshing of the first bevel gear 11 and the fourth bevel gear 20, the winding drum 7 is driven to rotate, thereby realizing the unwinding of the sunshade cloth 23. At the same time, the meshing of the third bevel gear 19 and the second bevel gear 14 drives the lead screw 13 to rotate, which causes the connecting rod 10 to move outward along the slide rod 15, thereby causing the first rotating rod 8 and the second rotating rod 9 to rotate to a straight position, thus unfolding the sunshade cloth 23 for sunshade.

[0028] The backlash of the first bevel gear 11, the second bevel gear 14, the third bevel gear 19, and the fourth bevel gear 20 is ≤0.1mm, and there will be no jamming.

[0029] The bottom of each of the four corners of the scaffold frame 1 is fixed with a support leg 2 by bolts. The support leg 2 increases the support area between the scaffold and the ground, thus facilitating the stable placement of the scaffold.

[0030] Ladders 3 are welded to both ends of the scaffold frame 1, and workers climb onto the standing board 4 via the ladders 3.

[0031] A railing 5 is welded to the top of the standing platform 4 to protect the workers and prevent them from falling.

[0032] The outer wall of the handle 18 is provided with anti-slip grooves, which facilitates the operation of the handle 18.

[0033] One of the mounting columns 6 is fixed with a protective shell 21 by bolts. The protective shell 21 covers the outside of the first bevel gear 11, the second bevel gear 14, the third bevel gear 19 and the fourth bevel gear 20, preventing dust and debris from entering and extending the service life of the equipment.

[0034] A corrugated pipe 22 is bolted between the support frame of the mounting column 6 and the protective shell 21. The corrugated pipe 22 has a sliding groove. The corrugated pipe 22 is sleeved on the outside of the lead rod 13 without contacting it, so as not to affect the movement of the connecting rod 10, thereby protecting the lead rod 13.

[0035] The working principle of this embodiment is as follows: When in use, first, the scaffolding is moved to the construction site. Then, the support leg 2 increases the support area between the scaffolding and the ground, which facilitates the stable placement of the scaffolding. Next, the workers climb the ladder 3 onto the standing board 4 and use the railing 5 to protect the workers and prevent them from falling.

[0036] Then, turning the handle 18 drives the transmission rod 17 to rotate, which in turn drives the third bevel gear 19 and the fourth bevel gear 20 to rotate. Under the action of the first bevel gear 11 and the fourth bevel gear 20 meshing, the winding drum 7 is driven to rotate, thereby realizing the unwinding of the sunshade cloth 23. At the same time, under the action of the third bevel gear 19 and the second bevel gear 14 meshing, the lead screw 13 is driven to rotate, which causes the connecting rod 10 to move outward along the slide rod 15, thereby causing the first rotating rod 8 and the second rotating rod 9 to rotate to a straight position, thereby unfolding the sunshade cloth 23 to provide sunshade and effectively blocking direct sunlight.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. 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.
