Description

Scaffolding frame for turbine case

The present invention relates to a scaffold frame for a turbine case, and more particularly, to a turbine case scaffold frame that can be firmly and securely assembled on the upper side of a turbine for a power plant of a circular tank shape.

In general, if you want to install the scaffolding frame vertically installed a plurality of scaffolding frame at regular intervals, where the scaffolding frame is not flat and the height is not constant, so the scaffolding frame with a screw jack installed at the bottom It is installed vertically, and a plurality of scaffolding frames installed vertically are installed firmly by intersecting braces and the like between the vertically mounted scaffolding frames.

Conventionally, Utility Model Registration No. 20-410996 (railing structure of a construction scaffolding frame) is used, but such a conventional scaffolding frame takes a long time to be installed from around a tank, such as a turbine of a power generation facility. The situation is that it is installed directly on the upper part of the cylindrical tank so that it can be worked quickly. At this time, the material of friction material is combined to the balance of the base of the scaffold frame so that the scaffold frame is fixed for a certain time by the balance and friction force. To maintain.

However, such a conventional scaffold frame, because the operator of the scaffold frame has to work on the upper part, the center of gravity of the scaffold frame is likely to cause the shape to be pulled to one part, thereby causing the scaffold frame to fall to one side and always carry the risk of falling accident. In addition, there was a very high risk of collapse and even serious safety accidents and human injury.

Moreover, there has been a continuous demand for the development of new scaffolding frames that can be secured by securing the scaffolding frames to a minimum size when working on a very large cylindrical tank.

Therefore, the main object of the present invention is to provide a turbine case scaffolding frame that can be securely installed in the upper portion of a large tank, such as a turbine case of the power plant to work safely.

Another object of the present invention is to provide a turbine case scaffolding frame for easy and simple installation and dismantling of the scaffolding frame so that it can be installed and dismantled quickly and safely.

In order to achieve the above object, the turbine case scaffolding frame of the present invention is installed in the upper portion of the tank-shaped turbine case formed in a circular form, but in the scaffolding frame is coupled by fastening the transverse pipe and the post with a fastening member; A horizontal plate having a vertical support bolt coupled to a lower end of the support but fastened to form a screw hole of the nut vertically, but vertically fastened to a screw hole of the nut so that the lower end is caught by the flange end of the turbine case; And a vertical plate having horizontal support bolts which are integrally coupled to the left and right sides of the horizontal plate and drilled one or more screw holes laterally and fastened to the screw holes to press the flange side of the turbine case. The basic features of the technical configuration.

Therefore, the scaffold frame for the turbine case of the present invention manufactures the required frame and places it in the upper part of the turbine case. The left and right vertical plates are inserted into the flange protruding from the turbine case, the scaffold frame is leveled, and then the horizontal support bolts are fastened The horizontal support bolt is fixed while pressing the flange and the vertical support bolt is fastened to the nut of the vertical plate so that the bottom of the vertical support bolt is in close contact with the end of the flange so that the bottom of the scaffold frame is firmly fixed to the top of the turbine case. In addition, when long loads are required for a long time, the fastening hole is drilled in the flange of the turbine case, and the horizontal support bolt can be tightened more firmly by matching the fastening hole between the screw hole and the hole corresponding to the vertical plate. In the upper part of the extra large tank such as the turbine case of the power generation facility The value will be effective for quick and easy installation and disassembly as well as to work safely.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figures 1 to 5, the scaffold frame 100 for the turbine case 1 of the present invention is installed on the tank-shaped turbine case 1 formed in a circular shape, but the transverse pipe 111 and the support 114 In the scaffolding frame (100) to combine); A horizontal plate 210 having a vertical support bolt 212 coupled to a lower end of the support 114 but fixed to form a screw hole of the nut 211 vertically and fastened to the nut 211; And a vertical plate 220 having a horizontal support bolt 222 which is integrally coupled to the left and right sides of the horizontal plate 210 and drills one or more screw holes 221 laterally and fastens to the screw holes 221. ).

The horizontal plate 210 is coupled to the lower end of the support 114, the nut 211 is fixed horizontally so that the screw hole is vertically positioned through the resin support bolt 212 perpendicular to the screw hole of the nut 211 ) To engage the projecting end of the flange (11) of the turbine case (1).

Here, the nut 211 may be substituted by vertically drilling a screw hole directly in the horizontal plate 210.

The vertical plate 220 is integrally coupled to the left and right sides of the horizontal plate 21 by drilling a plurality of screw holes 221 in the horizontal direction and fastening the horizontal support bolt 222 to the screw holes 221. The diameter of the flange 11 of the turbine case 1 can be reduced while pressing.

Here, the left and right vertical plates 220 form one or more screw holes 221 in one vertical plate 220 and one or more corresponding holes 224 in the other vertical plate 220, but one vertical plate 220. The fastening hole 223 corresponding to the screw hole 221 and the other vertical plate 220 of the c) may be drilled into the flange 11 of the turbine case 1.

In this case, the hole 224 in the screw hole 221 and the other vertical plate 220 of the one side vertical plate 220 coincides with the fastening hole 223 to be penetrated by the horizontal support bolt 222.

On the other hand, the scaffolding frame 100 can be formed in a variety of shapes, by coupling the transverse pipe 111 to the support 114 as a fastening member 112, but as necessary to couple the support plate 113 to a desired position It is preferable to selectively form and use the frame 110 of various shapes.

Referring to the operation of the turbine case scaffolding frame according to the present invention as follows.

First, the transverse pipe 111 and the support plate 113 are coupled to the support 114 by the fastening member 112 to produce the frame 110 as necessary, and placed on the upper portion of the turbine case 1 by a crane or the like.

In this case, the frame 110 is coupled to the position of the coupling body 200 coupled to the lower end of the support 114 to correspond to the flange 11 of the turbine case 1 to complete the desired scaffolding frame 100.

Here, the frame 110 of the scaffolding frame 100 may be formed by fastening in various orders as necessary.

In such a state, the left and right vertical plates 220 are inserted into the flanges 11 protruding from the turbine case 1, the scaffolding frame 100 is leveled, and the horizontal support bolts 222 are fastened to the horizontal support bolts 222. To be fixed while pressing the flange (11).

Here, the vertical support bolt 212 is fastened to the nut 211 of the vertical plate 210 so that the lower end of the vertical support bolt 212 is in close contact with the end of the flange 11.

Therefore, the lower end of the scaffold frame 100 is to be firmly fixed to the upper portion of the turbine case (1).

Meanwhile, the fastening hole 223 is drilled in the flange 11 of the turbine case 1, and the fastening hole 223 is matched between the screw hole 221 and the hole 224 corresponding to the vertical plate 220. Since the horizontal support bolt 222 is fastened so that the horizontal support bolt 222 is fastened through the flange 11, it may be more firmly coupled.
