Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a mobile scaffolding device, and particularly to a mobile scaffolding device used when scaffolding is temporarily required at a work site or the like.

[Background of the idea]

At work sites, scaffolding may be built at a higher location than the floor. This kind of scaffolding is temporary and needed temporarily, and after the work is completed,
must be removed. Therefore, mobile scaffolding devices are desirable for such scaffolding. A mobile scaffolding device is usually considered to be composed of a cart, a post that is set up on the cart and can be moved up and down, and a scaffold at the upper end of the post. When using such a scaffolding device, the device is moved to a working position, the cart is fixed to the floor, and the posts are set at the required height to construct the scaffold. However, the scaffolding constructed in this way limits the scope of work once the trolley is fixed. Therefore, even when it is desired to set up a scaffold at a slightly distant location from the scaffold that has been built, there is a problem in that the cart must be moved each time.

Furthermore, if the post is extended long or a large weight is applied to the scaffold, the rotational moment applied to the post will increase, which may cause the scaffold device to tilt.

[Purpose of invention]

The present invention was developed in view of these circumstances, and the purpose is to propose a mobile scaffolding device that allows the scaffolding to be moved over a wide range even when the trolley is fixed, and that can be used safely even when a large weight is applied to the scaffolding. It is said that

[Summary of the idea]

In order to achieve the above-mentioned object, the present invention includes a cart, a post installed on the cart, a ceiling holder provided at the upper end of the post so as to be movable in the vertical direction and capable of contacting the ceiling, and an outer periphery of the post. A cylindrical body is provided to be movable up and down, an arm whose base end is rotatably provided on the outer periphery of the cylindrical body and is configured to be extendable and retractable in the horizontal direction, and a scaffold formed at the tip of the arm. It is characterized by consisting of.

〔Example〕

Preferred embodiments of the mobile scaffolding device according to the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is a front view of a mobile scaffolding device according to the present invention. As shown in FIG. 1, the mobile scaffolding device 10 has a cart 12 at the bottom, and wheels 14, 14, 14, 14 (in the figure, two
(Only shown in the figure) is provided. Further, an anchor bolt 1 is attached to the main body 10 via mounting plates 15, 15.
6, 16, 16, 16 (only two bolts are shown in the figure) are provided, and the bolts 16 are brought into contact with the floor surface 17 when the main body 10 is installed, and support the truck 12 immovably.

A post 18 is erected at the center of the upper surface 12B of the truck 12, and a rod 20 is mounted at the upper end 18A of the post 18.
is provided. The rod 20 is attached so as to be extendable and retractable, and is extended and contracted by, for example, a hydraulic device (not shown) inside the post 18. Upper end 20 of rod 20
A ceiling support 22 is provided at A, and the ceiling support 22 comes into contact with a ceiling surface 23 when the rod 20 is extended by the hydraulic system. This allows the scaffolding device 10 to
and the ceiling surface 23.

Further, a cylindrical body 24 is provided on the outer periphery of the post 18, and this cylindrical body 24 is attached to the post 18 in a vertically movable state by a hydraulic device or the like. Further, on the outer periphery of the cylinder body 24, an arm 28 is provided at its base end 2.
It is provided so that it can rotate around 6. This arm 28 is configured to be extendable and retractable, and has a scaffold 30 at its tip.
is formed. As a result, the scaffold can move up and down, and can move throughout the circumferential range whose radius is the maximum extension of the arm 28.

In this embodiment configured as described above, the scaffolding device 10 is installed on a cart 1 at a work place requiring scaffolding.
2, the anchor bolt 16 is brought into contact with the floor surface 17, and the main body 10 is supported on the floor surface 17 so as not to move during work. Further, the rod 20 of the post 18 is extended and the ceiling support 22 is brought into contact with the ceiling surface 23, so that the scaffolding device 10 is supported by the floor surface 17 and the ceiling surface 23. Further, the scaffold 30 provided on the arm 28 can be adjusted to a predetermined height by the vertically movable cylindrical body 24, and further moved to a required position by the rotation, extension and contraction of the arm 28. As a result, the work range by the scaffolding 30 becomes wider,
Further, even if a heavy object is placed on the scaffold 30, the main body 10 will not fall sideways because it is supported by the floor surface 17 and the ceiling surface 23.

In the embodiment described above, even when it is difficult to construct the scaffold due to obstacles etc., the arm 28 is extended and the scaffold 30 is
This improves work efficiency.

Furthermore, in the embodiment described above, since the trolley 12 can be made lightweight, it can be easily carried.

Further, FIGS. 2 and 3 show a modification of the ceiling support 22. In this embodiment, as shown in FIGS. 2 and 3, a ceiling support 32 is pivoted to the upper end of the rod 20 by a pin 34, and the ceiling support 32 is mounted as shown in phantom lines in FIG. It is configured to be tiltable. In such a configuration, even if the ceiling surface 23 is not horizontal and has a slight inclination (irregular surface), the rod 20 can be extended to reliably contact the ceiling support 32, and the scaffolding device 10 can be support is possible. Therefore, in this embodiment, since the ceiling surface 23 is not limited to a horizontal surface, the scope of application at a work site is expanded.

[Effect of idea]

As explained above, according to the mobile scaffolding device according to the present invention, the mobile scaffolding device can be supported by the floor and ceiling, so even if a large weight is applied to the scaffolding, work can be carried out safely, and the work can be carried out horizontally. By providing a scaffolding that can be rotated in any direction and expanded and contracted, work can be carried out over a wide range even when the trolley is fixed.
