[0001] Lifting device of weight [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lifting device for a weight lifting device, and more particularly to a lifting device for lifting or lifting a weight lifting device such as a pumping pump or a bottom ring installed in a water turbine.

The energy source for power generation includes water potential energy, thermal energy of fossil fuel, and fission energy of nuclear fuel. Hydrogen generation, thermal power generation and nuclear power generation can be categorized according to the generation method using such energy.

In Korea, nuclear power plants and nuclear power plants are mainstays because they are focused on the construction of thermal power plants that can build large-capacity power plants in a short period of time and nuclear power plants that have relatively low fuel costs in order to cope with the demand for electricity due to rapid economic growth.

Large-capacity thermal power plants and nuclear power plants are operated as power plants for base load operation at all times because of their operation characteristics. As a result, it became necessary to secure load facilities to consume midnight power and secure power plants for peak load. Of the power plants for peak load, there are general hydroelectric power plants and pumped-storage power plants as hydropower generation facilities, and general hydropower is practically impossible to keep up with the rapidly increasing power demand due to limited resources available.

In recent years, surplus power is generated at nighttime light loads due to the operation of thermal power plants and nuclear power plants due to the pattern of power consumption which shows a considerable gap between daytime and nighttime. Accordingly, a pumped-storage power generation system is utilized to utilize surplus power at nighttime and appropriately supply necessary power at peak load.

Pumped-water power generation uses a surplus electric power generated from other power plants at night or light load by using a pumping pump to raise water at a lower place to a higher place and to generate electricity using the pumped water. Although there is a drawback, it is economical in that it uses surplus power at the late night, it is possible to increase the capacity of power generation facilities, and the construction unit cost is relatively low, so it is operated as power generation facility for peak load.

In this way, a return channel (RETURN CHANNEL) is located in a pumping pump used in a pumped-storage power plant, and a HEAD COVER that surrounds a 2nd runner is installed at an upper portion of the return channel. A bottom ring that surrounds a first runner (not shown) of the lens barrel is installed. Upper and lower guide vanes are installed at the top and bottom of the bottom ring.

In the conventional lifting device, the lower wicket gate and the housing provided in the bottom ring are separated and then lifting equipment is installed in the housing hole to be disassembled or assembled .

Here, the top gate and the housing are composed of 20 components, each one of which is lifted through a crane to a storage place, lifting the bottom ring, so that the work time and manpower are excessively consumed, and there is a risk of unnecessary processes and safety accidents There was a problem.

In addition, since it is necessary to use only a wire rope to turn over the bottom ring in the past, it takes a long time to work, and if a wire rope breaks during operation, a safety accident such as personal injury may occur There was a problem.

Korean Patent No. 10-0836894
