Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for covering high-place girders, such as slates, etc., bridged at high places in cement factories and other places.

When a conveyor line is installed on a high girder built on a particularly high pier in a cement factory or a facility for importing and unloading coal and ore, etc., in order to surround the conveyor line with, for example, slate, it is necessary to Because the construction involved construction work at a site, safety measures were difficult, such as installing safety nets to prevent people or equipment from falling and constructing scaffolding from below, which caused the problem of increasing construction costs.

Therefore, the present invention has been developed to provide a method for covering work such as slate covering on both sides of high-place girders built on multiple piers, and if necessary, on the ceiling, which can be carried out safely and at low cost. This was done for the purpose of providing equipment.

That is, the device of the present invention is provided with a movable trolley that is movable on a removably temporarily installed rail at the top of a truss of a high-place girder built on a plurality of piers, and at least each It is constructed by providing left and right side covering scaffolds that can be opened outward in a range where the lower ends do not interfere with the piers.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic perspective view of a high-place girder during slate tensioning work to which a high-place girder slate tensioning device according to an embodiment of the present invention is applied; FIG. 2 is an enlarged side view of the slate tensioning device of FIG. 1, FIG. 3 is a plan view of FIG. 2, and FIG. 4 is a front view of FIG. 2.

First, as shown in Fig. 1 and Fig. 2, plates are installed on both sides of the truss of the conveyor line 3 installed in the high-place girder 2 constructed on a plurality of piers 1, and if necessary on the ceiling surface. In order to stretch the shaped slate 4, a rail 5 of an appropriate length, for example, 10 m, is temporarily installed on the top of the truss of this conveyor line 3, and the wheels 6 are used to move the rail 5 over the rail 5, or the arrow F is moved by power. A moving cart 7 as shown in FIGS. 2 to 4 is provided which is movable in the directions shown in FIG.

A ceiling slate covering scaffold 8, which is a ceiling covering scaffold, is provided on the top of the mobile cart 7, if necessary, and a safety fence 9 for covering the ceiling slate is provided around the ceiling slate covering scaffold 8. There is.

Next, side scaffolds 11 and 12 are provided on both left and right sides of the moving trolley 7 as scaffolding platforms for slate tensioning on both side trusses of the conveyor line 3, and these side slate tensioning scaffolds 11 and 12 are installed on the upper part of the slate tensioning scaffolds 11 and 12. are supported on the movable cart 7 so as to be able to open outward in the directions of arrows L and R, respectively, using a hinge 13 as a fulcrum, and the outward opening operation is performed by hydraulic cylinders 14 and 1.
4, the angle of outward opening is
When this movable trolley 7 moves over the pier 1 shown in FIG. 1, the lower portions of the slate-covered scaffolds 11 and 12 do not interfere with the pier 1.

By using the slate tensioning device of the present invention, that is, the coating device having the above configuration, the removable rail 5 temporarily installed on the top of the truss of the conveyor line 3 can be used.
Personnel and equipment entered the entrances and exits 11A and 12A in Figure 3 into the slate-stretching scaffolds 11 and 12 on the left and right sides of the mobile trolley 7, which was straddled like a monorail, and carried out slate-stretching work on the sides. After that, while moving the movable trolley 7, the ceiling slate is stretched using the ceiling slate tensioning scaffold 8 and its safety shelf 9 as necessary, and the work is carried out safely while gradually relocating the rail 5 in the traveling direction F. You can go there.

In this case, when passing through the pier 1 part, the left and right side slate scaffolding 11, 12 is moved by the hydraulic cylinder 1.
4 and 14 to open outward, the pier 1
There is no interference between the two and it can pass smoothly.

Therefore, by using the device of the present invention, it is possible to safely and smoothly perform slate work on both sides of high-place girders and, if necessary, on the ceiling. There is no need to assemble it from scratch, which has the effect of significantly reducing the construction cost, including the cost of safety measures.
