Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mobile work scaffold (also referred to as a rolling tower) mainly used for work in high parts such as ceiling work.

[0002]

[Prior Art]

 Generally, a mobile work scaffold is a work scaffold with a plurality of wheels (casters) that can freely move back and forth and left and right, and is widely used mainly when performing high ceiling work.

[0003]

[Problems to be solved by the device]

 However, in the conventional mobile work scaffolding, the ladder for climbing up and down is formed vertically on the outer periphery of the scaffolding, so climbing up and down is extremely difficult. Also, if the scaffolding is high, there is a risk of falling, and climbing and descending was extremely dangerous.

The present invention has been proposed in order to solve the above-mentioned conventional problems, and an object thereof is to provide a mobile work scaffold capable of extremely safe climbing and descending.

[0005]

[Means for Solving the Problems]

 In the mobile scaffold according to the present invention, the cloth plate is installed between the horizontal members of the left and right ladder frames facing each other, the upper end of the inner staircase is fixed to one horizontal member of the left and right ladder frames, and the lower end of the cloth plate is It is fixed slightly inside from the end.

【Example】

 1 and 2 show an embodiment of a mobile work scaffold according to the present invention. The mobile work scaffold 1 includes a plurality of ladder frames 2, a plurality of cloth plates 3 and a plurality of It consists of stairs 4 and.

In the ladder frame 2, the upper and lower horizontal members 2b and 2b are horizontally installed at the upper and lower ends of the left and right columns 2a and 2a, and the intermediate column 2c is installed at the center between the upper and lower horizontal members 2b and 2b. A plurality of stepping members 2d are horizontally attached at predetermined intervals in the vertical direction between the column 2a and the intermediate column 2c to be integrally configured. Steel pipes are used for all the components of the ladder frame 2. The step member 2d is used as a ladder for going up and down.

The ladder frames 2 and 2 thus configured are connected to each other at a desired height by vertically connecting the left and right columns 2a and 2a, and the ladder frames 2 and 2 are connected in the same number. Are installed facing each other in parallel. At the lower end of the left and right stanchions 2a, 2a of the lowermost ladder frame 2, wheels (not shown) that can freely travel forward, backward, left and right, and outriggers (not shown) that support the ladder frame 2 so as not to fall are provided. Each is installed.

The cloth plate 3 is formed in the shape of a rectangular plate that is longer than the steel plate, and hooks 3a, 3a are formed at both ends thereof. Then, the cloth plate 3 is horizontally installed between the opposing ladder frames 2 and 2 of the same height, and both ends thereof are hooked by hooks 3a and 3a on the upper horizontal members 2b and 2b of the ladder frame 2 and 2, respectively. It is connected.

[0010] Furthermore, the cloth plates 3 which are erected between the ladder frames 2 and 2 having the same height are laid one by one by a width of one cloth plate so that they do not overlap vertically, and are alternately staggered horizontally. There is. A brace 5 is installed between the columns 2a, 2a of the facing ladder frames 2,2. Since the cloth plate 3 and the brace 5 are thus installed between the opposing ladder frames 2 and 2, the shape of the movable scaffold 1 as a whole can be maintained and can be self-supporting.

Hooks 6,6 are formed at the upper ends of the left and right side plates 4a, 4a of the inner stairs 4, and L-shaped receiving parts 7,7 are formed at the lower ends. The inner staircase 4 is installed between the upper end horizontal member 2b and the cloth plate 3 on one side of the opposite ladder frame 2, the upper end is fixed by hooking hooks 6 and 6 on the upper end horizontal member 2b, and the lower end is a receiving portion. It is fixed by hooking 7,7 on the left and right edges of the cloth plate 3. In this case, the lower end of the inner stairs 4 is fixed slightly inward of the leading end of the cloth plate 3 so that the leading end of the cloth plate 3 constitutes the landing 3a of the inner stairs 4.

The upper and lower inner stairs 4, like the upper and lower cloth plates 3, are horizontally arranged alternately. Therefore, in the mobile work platform 1, a folded staircase that is continuous from the uppermost cloth plate 3 to the lowermost cloth plate 3 is formed, and a part of the cloth frame 3 forms the landing 3a.

The ladder frame 2, the cloth plate 3, the inner stairs 4 and the brace 5 can be easily removed, and the number of these members can be appropriately increased or decreased according to the work place. The height can be adjusted freely.

[0014]

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects.

Since it is possible to go up and down along the inner stairs, it is possible to prevent a fall accident and it is extremely safe. In addition, it is possible to go up and down with the material, which makes the work extremely easy. Moreover, since the ladder frame, the cloth plate, the inner staircase and the brace can be easily removed, the height can be freely adjusted by appropriately increasing or decreasing the number of these members according to the work place. Furthermore, part of the cloth board functions as a landing for the inner stairs, so no parts dedicated to the landing are required, which is extremely economical.
