Description

Technical Field

[0001] The utility model relates to the field of scaffolds, and in particular to a scaffold that can be deployed and fixed. Background Art

[0002] A scaffold is a structure used to provide a working platform and support on construction sites, repairs, renovations, etc. It is usually made of metal or wood and is used to support workers, tools and materials so that they can work safely and efficiently. The scaffold enables them to carry out construction, renovation or repair work at height without worrying about balance or safety issues.

[0003] However, most of the scaffolding now has the following problems:

[0004] First, the existing scaffolding is mostly assembled when in use. It is troublesome to move the place of use after installation. It is time-consuming and laborious to dismantle and rebuild. When the pulley is installed at the bottom for movement, it is easy to cause poor stability in use, and it is inconvenient to move and adjust the use of the equipment.

[0005] Second, the existing scaffolding has a limited standing platform during operation. During construction, only a certain range can be constructed. The limited standing area makes it difficult for multiple people to construct at the same time. It is troublesome to use and inconvenient to adjust the use area of ​​the equipment.

[0006] Therefore, we made improvements on this and proposed a scaffold that can be deployed and fixed. Utility Model Content

[0012] As a preferred technical solution of the utility model, the second bevel gears are symmetrically distributed on the left and right sides of the first bevel gear, and the second bevel gears correspond one-to-one with the push blocks through the connecting shaft.

[0013] As a preferred technical solution of the utility model, the connecting shaft is fixedly connected to the center of the second bevel gear, and the cross section of the push block is in the shape of a water drop.

[0014] As a preferred technical solution of the utility model, the springs are arranged in two groups, the two groups of springs are symmetrically distributed on the left and right sides of the connecting plate, and each group of springs is equidistantly distributed on the connecting plate.

[0015] As a preferred technical solution of the utility model, the output shaft of the second servo motor is fixedly connected to the center of one end of the bidirectional threaded rod, and the bottom end surface of the moving block is in contact with the bottom end surface inside the support plate.

[0016] As a preferred technical solution of the utility model, the slider is fixedly connected to the extension plate, a ladder is installed on the support plate, and the sliders are equidistantly distributed on the extension plate.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] In the solution of the utility model:

[0019] 1. Through the push block that is set, when moving, the first servo motor on the support frame can be turned on, the first servo motor drives the first bevel gear to operate, when the first bevel gear rotates, it can drive the connecting shaft to rotate through the second bevel gear, the connecting shaft can smoothly drive the push block to operate, when the push block rotates, the longer end can smoothly push the connecting plate to move, when the connecting plate moves, it can push the pulley down, and at the same time, the movement of the connecting plate can pull the spring, and after the pulley is pushed out, the equipment can be smoothly pushed to move through the pulley, so that it can be adjusted and used according to the usage.

[0035] Embodiment 2:

[0036] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

[0037] like Figure 5 As shown, as a preferred embodiment, on the basis of the above method, further, the second bevel gear 4 is symmetrically distributed on the left and right sides of the first bevel gear 3, and the second bevel gear 4 corresponds to the push block 6 one by one through the connecting shaft 5, which can ensure that the push blocks 6 on both sides can smoothly push the connecting plates 8 on both sides to drive the pulley 9 to move downward.

[0038] like Figure 3 As shown, as a preferred embodiment, on the basis of the above method, further, the connecting shaft 5 is fixedly connected to the center of the second bevel gear 4, and the cross-section of the push block 6 is teardrop-shaped, which can ensure that the longer end of the teardrop-shaped push block 6 can smoothly push the connecting plate 8 to move downward.

[0039] like Figure 5 As shown, as a preferred embodiment, on the basis of the above method, further, two groups of springs 7 are provided, and the two groups of springs 7 are symmetrically distributed on the left and right sides of the connecting plate 8, and each group of springs 7 is equidistantly distributed on the connecting plate 8, which can ensure that the springs 7 on both sides can smoothly pull the connecting plate 8 to move.

[0040] like Figure 2As shown, as a preferred embodiment, on the basis of the above method, further, the output shaft of the second servo motor 11 is fixedly connected to the center part of one end of the bidirectional threaded rod 12, and the bottom end surface of the moving block 13 is in contact with the inner bottom end surface of the support plate 10, which can ensure that the moving block 13 can move smoothly through the support of the inner bottom end surface of the support plate 10 when moving.

[0041] like Figure 6 As shown, as a preferred embodiment, on the basis of the above method, further, the slider 17 is fixedly connected to the extension plate 15, a ladder 18 is installed on the support plate 10, and the sliders 17 are evenly distributed on the extension plate 15, which can ensure that multiple sliders 17 can stably support the extension plate 15 to move.

[0042] Specifically, the deployable fixed scaffolding is used in combination with Figure 1-6 When it is necessary to drive the equipment to move and adjust the use position, the first servo motor 2 on the support frame 1 can be turned on, and the first servo motor 2 drives the first bevel gear 3 to operate. When the first bevel gear 3 rotates, it can drive the connecting shaft 5 to operate through the second bevel gear 4. When the connecting shaft 5 rotates, it can smoothly drive the push block 6 to rotate. When the push block 6 rotates, the longer end of the push block 6 can push the connecting plate 8 downward, and the connecting plate 8 can push the pulley 9 out of the support frame 1 when it moves. At the same time, the connecting plate 8 can squeeze the spring 7 when it moves, and the pulley 9 can be used to conveniently drive the equipment to move and adjust the use position. After the adjustment is completed, in order to avoid the shaking of the equipment, the first servo motor 2 can be controlled to drive the connecting shaft 5 to rotate in the opposite direction.

[0043] When in use, workers can climb up to the support plate 10 through the ladder 18 to perform aerial work. If the use area of ​​the support plate 10 needs to be adjusted, the second servo motor 11 can be turned on without retracting the pulley 9. The second servo motor 11 drives the bidirectional threaded rod 12 to operate. When the bidirectional threaded rod 12 rotates, it can drive the moving blocks 13 on both sides to move within a limited position. When the moving blocks 13 on both sides move inward at the same time, the extension plate 15 can be pushed to move by the pushing plate 14. When the extension plate 15 moves outward, it can be smoothly moved under the sliding support of the slider 17 in the slide groove 16. The extension plate 15 pushes the support frame 1 to move outward. Through the cooperation of the support plate 10 and the extension plate 15, the use area can be increased, which is convenient for adjustment according to the usage situation.
