Description

[Detailed explanation of the idea] The present invention relates to a movable scaffolding roller unit.

The guide rollers of conventional self-propelled high-rise scaffolding units are fixed to the scaffold frame and do not have a mechanism for adjusting the height, so the range of use of the self-propelled scaffold is limited.

The present invention was proposed in view of the above circumstances, and aims to provide a movable scaffolding roller unit that does not have any power and uses only a roller mechanism to prevent falling while moving along a target structure. For the purpose of
A flange-equipped guide roller, and a flange that protrudes horizontally from the upper part of the other side of the roller unit plate and rolls horizontally by coming into contact with a horizontal guide rail that protrudes from the upper end of the structure. It is characterized by comprising a guide roller.

An embodiment in which the present invention is applied to ship construction at a dock will be explained with reference to the drawings. Fig. 1 is a partial perspective view, Fig. 2 is a front view of Fig. 1, Fig. 3 is a plan view of the device, and Fig. 3 is a plan view of the device. Figure 4 is a side view of Figure 3, and Figure 5 is a side view of Figure 3.
The figure is a front view of FIG. 4.

In the above diagram, ST is a movable scaffolding stage approximately 15.5M in height attached along the outer skin of the hull SH to be constructed, and the movable scaffolding stage ST is a movable scaffolding stage attached to the outer skin of the hull SH using the invented device attached at three locations. It is attached along and can be moved horizontally along it. 1 is the upper edge of the upper deck of the new ship hull, 2 is 150
A movable scaffolding column 3 made of mm x 100 mm x 6 mm/9 mm I-beam steel is pivoted in a cantilever manner on a short shaft protruding from the hull side of a roller unit plate 5 measuring 40 mm x 300 mm x 400 mm. A flanged horizontal moving roller with a diameter of 260 mm that rolls horizontally along the upper edge of the upper deck.
Reference numeral 4 denotes four flanged vertically movable rollers each having a diameter of 110 mm, each of which is cantilever-likely pivoted to short shafts protruding from the other surface of the roller unit plate 5 in a rectangular distribution.
A movable scaffolding support 2 is vertically slidably guided between flanged rollers 4, 4.

According to such a device, the horizontally moving rollers 3 move on the upper edge 1 of the upper deck, and the vertically moving rollers 4 move the roller unit plate 5 in the vertical direction while holding the movable scaffolding support 2; The movable scaffolding is created by engaging the collar of the horizontally moving roller 3 with the upper edge 1 of the upper deck.
ST's fall is prevented.

Therefore, according to such a device, the movable scaffold ST is moved to the hull outer plate by a total of five rollers, including four vertically moving rollers protruding from the roller unit plate 5 and one horizontally moving roller. It can be moved horizontally and vertically without tipping over, without the need to attach any pieces to the hull.

In short, according to the present invention, there are four flanged guides distributed in a rectangular shape on one side of the roller unit plate, each protruding horizontally, and guiding the self-propelled scaffold support in the vertical direction along the surface of the roller unit plate. and a flanged guide roller that protrudes horizontally from the top of the other side of the roller unit plate and rolls horizontally by coming into contact with a horizontal guide rail that protrudes from the top end of the structure. As a result, a movable scaffolding roller unit with a simple structure and low cost can be obtained, so the present invention is extremely useful industrially.
