Description

A Safety Workbench for eleminating Clinker}

The present invention relates to a safety workbench for removing clinker, and more particularly, so that the coal ash attached to the super heater in the furnace of a thermal power plant is melted and mounted on a column spaced apart from an inclined structure in order to remove the stone deposit fixed in a lump. The inclined base is closely attached and the connecting means is placed between the hook-shaped fixing means that are coupled to the inclined base, and the ladder-shaped body is fixed to the connecting means, and the support is joined at an angle from the body, and a horizontal structure is placed between the support and the body. By installing and installing a scaffold between horizontal structures and installing a safety bar from the top of the horizontal structures, the steel pipe scaffolding is designed in a system scaffolding type that is easy to assemble, creating a smooth working environment for workers, and to a safety workbench for removing clinker that can work safely. About.

In general, in order to check the ceiling structure, which is the top of a large structural material such as a boiler of a power plant, a scaffold is assembled from the ground and climbed.

Conventionally, in the method of stacking scaffolding from the bottom of the boiler to the top of the boiler, the place to work is the top part. For this work, unnecessary work is required to construct a scaffold in the middle from the top to the floor. There is a disadvantage of having to stack a scaffold with a height of 60m when maintaining or constructing such facilities at about 60m.

To improve this, the method of using a scaffold hanging on the top of the structure is used, and the conventional method of using a scaffold hanging on the top of the structure is the top plate of the bridge in "Fixing Device for Aerial Scaffolding" for Korean Registered Office No. 20-0392341. In assembling a scaffold for inspection or construction, an aerial scaffolding is disclosed that uses a wire rope that has one end connected to a fixed part of the bridge and the other end detachably connected to a steel pipe that is a horizontal member of the aerial scaffold. . In addition, U.S. Patent No. 6817444 Suspended work platform discloses a method and apparatus for constructing a temporary work platform by suspending a wire from the ceiling of a structure such as a bridge and connecting the lower portion thereof with a steel pipe as a horizontal member.

However, there is a problem in that the conventional method and apparatus for using the scaffold suspended from the ceiling can be shaken in both directions by hanging it with a wire from the ceiling without supporting it from the floor surface, and thus the working environment is unstable and safety is poor.

In particular, in thermal power plants, there is no scaffolding system for maintenance that has received safety certification in Korea due to the special structure and shape of the boiler, and there is no maintenance countermeasure for emergency maintenance due to accidents such as an accident in which the super heater tube is worn or ruptured. State.

As such, there is a risk of safety accidents when installing and dismantling scaffolding for maintenance of boilers in thermal power plants, and the boiler tube has a complex structure and a narrow space, making it difficult to inspect, and because there are many working areas at high places, there is a high risk during inspection and repair work. In addition, there is always a risk of wear, rupture, and shock to the boiler tube during operation of the power plant, but there is currently no suitable inspection system scaffolding, so a customized steel pipe scaffolding must be installed on the site.

However, the steel pipe scaffolding used in the planned preventive maintenance has a disadvantage that safety is not verified, such as structural review, and the installation manpower, cost, and process are increased due to the large number of installed members, and a professional manpower composed of skilled scaffolding is required.

In addition, there is a high risk of safety accidents due to the narrow working space when installing the steel pipe scaffolding in the nose during clinker work.
