[0001] The utility model relates to a scaffold, in particular to a movable scaffold. Background Art

[0002] Scaffolding is a working platform set up to ensure the smooth progress of each construction process. According to the location of the scaffolding, it can be divided into external scaffolding and internal scaffolding; according to different materials, it can be divided into wooden scaffolding, bamboo scaffolding, and steel pipe scaffolding; according to the structural form, it can be divided into vertical pole scaffolding, bridge scaffolding, door scaffolding, suspended scaffolding, hanging scaffolding, cantilever scaffolding, and climbing scaffolding.

[0003] For example, a movable scaffolding disclosed in a Chinese patent with publication number CN219509125U relates to the technical field of scaffolding, and includes a base, four evenly distributed first U-shaped frames are arranged at the bottom end of the base, four evenly distributed support plates are arranged on the sides of the base, the first U-shaped frames move toward or away from each other synchronously, and are used to drive the support plates to rotate upward or downward synchronously in a vertical direction, and rectangular frames are symmetrically arranged at the ends of the base, and a loading platform is arranged between the two rectangular frames, and the loading platform moves back and forth in a straight line in a vertical direction; the utility model drives the support plates to rotate upward or downward synchronously by the first U-shaped frames moving toward or away from each other synchronously, so as to facilitate the movement of the scaffolding or increase the stability of the scaffolding, and can save labor by vertically lifting the loading platform, with high efficiency and high safety.

[0004] Some problems were found when using the above-mentioned existing movable scaffolding. Firstly, although the support plates can effectively increase the stability of the scaffolding, the support plates cannot be adjusted individually. When used on inclined or bumpy ground, the scaffolding cannot remain in a vertical state, and it cannot even be adjusted by padding bricks like a traditional scaffolding. Secondly, when the scaffolding is working, the tools carried are often placed directly on the loading platform. Workers often kick the tools off with their feet when moving. In serious cases, the tools may trip the workers and cause serious accidents. Utility Model Content

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 1-3 The utility model provides a technical solution: a movable scaffolding, including a pipe rack 1, diagonal braces 2 are fixedly installed on both sides of the pipe rack 1, a nut 201 is embedded and installed near the edge of the other end of the diagonal brace 2, a threaded support rod 202 is rotatably installed in the nut 201, a base 206 is arranged below the threaded support rod 202, a tool storage basket 4 is arranged above the pipe rack 1, an annular base 401 is fixedly installed below the tool storage basket 4, the annular base 401 cooperates with the pipe rack 1, a pin hole 402 is opened in the annular base 401, and a limit pin 3 is arranged in the pin hole 402.

[0022] After the base 206 moves downward and contacts the ground, the threaded support rod 202 is further rotated to drive the base 206 downward. At this time, the base 206 will replace the roller 103 support device to act as a leg. After the roller 103 leaves the ground, the threaded support rod 202 can be rotated separately according to the vertical state of the pipe rack 1 to adjust the vertical state of the pipe rack 1, so that when it is used on a bumpy ground, the device can be easily adjusted to a vertical state. At the same time, tools can be placed inside the tool storage basket 4. The tool storage basket 4 is clamped on the protruding part of the upper end of the column of the pipe rack 1 through the annular base 401. The limit pin 3 can clamp the tool storage basket 4 and the pipe rack 1 together to prevent the tool storage basket 4 from falling. The tools are stored inside the tool storage basket 4. First, the worker's feet are prevented from contacting the tools. At the same time, since the tool storage basket 4 is located at a higher position above the column of the pipe rack 1, the worker does not need to bend over to take the tools.

[0023] Among them, in order to achieve the purpose of adjusting the pipe rack 1 to a vertical state, the present device adopts the following technical solutions: a roller 103 is rotatably installed on the pipe rack 1 and near the lower end, a ladder 102 is fixedly installed on the front of the pipe rack 1, a bearing plate 101 is fixedly installed inside the pipe rack 1, a through hole 104 is opened in the pipe rack 1 and near the upper edge, the through hole 104 cooperates with the limit pin 3, a rotating handle 203 is fixedly installed on the upper end of the threaded support rod 202, a spherical connector 204 is fixedly installed on the lower end of the threaded support rod 202, a ball seat 205 is rotatably installed on the spherical connector 204, and the bottom of the ball seat 205 is fixedly connected to the base 206.

[0024] The roller 103 facilitates the movement of the device, and the through hole 104 cooperates with the tool storage basket 4 so that the limit pin 3 can pass through the upper end of the pipe rack 1 column, thereby fixing the position of the tool storage basket 4. The ladder 102 facilitates workers to climb onto the load-bearing plate 101. The threaded support rod 202 can be driven to rotate by rotating the handle 203, and the spherical connector 204 is rotatably connected to the ball seat 205, so that the base 206 can rotate freely, so that the base 206 can fit the ground as closely as possible on bumpy roads.

[0025] Among them, in order to achieve the purpose of fixing the tool storage basket 4, the present device adopts the following technical solution: a memory metal ring 301 is fixedly installed at one end of the limit pin 3, and a lifting ring 302 is fixedly connected to the other end of the limit pin 3. A binding rope 303 is tied to the lifting ring 302, and the other end of the binding rope 303 is fixedly connected to the pipe rack 1. A handle 403 is rotatably installed on the outer wall of the tool storage basket 4.

[0026] The memory metal ring 301 is made of deformable metal. When the worker applies a certain pulling force, the memory metal ring 301 will deform so that the limit pin 3 can pass through the pin hole 402 and the through hole 104 normally, mainly to prevent the limit pin 3 from slipping due to vibration. The binding rope 303 connects the limit pin 3 to the pipe rack 1 to prevent the limit pin 3 from being lost due to being placed randomly after being removed. The handle 403 makes it convenient for workers to carry the tool storage basket 4 and move it.

[0027] The working principle and use process of the utility model are as follows: when in use, the device needs to be pushed to the specified position through the roller 103, and then the rotating handle 203 is rotated to drive the threaded support rod 202 to rotate. The rotation of the threaded support rod 202 can drive the base 206 to move down. After the base 206 moves down and contacts the ground, the threaded support rod 202 continues to be rotated. At this time, the base 206 will replace the roller 103 to become the device support leg. After the roller 103 is lifted off the ground at a certain distance, according to the horizontal state of the pipe rack 1, the threaded support rod 202 can be rotated alone to adjust the pipe rack 1 to a vertical state. Then, the ladder 102 is used to climb onto the bearing plate 101, and the tool storage basket 4 is placed on the upper end of the column of the pipe rack 1, so that the pin hole 402 is aligned with the through hole 104, and the limit pin 3 is inserted to fix the tool storage basket 4. At this time, the tool can be placed into the tool storage basket 4.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
