Abstract

The invention discloses a hoisting method used for a hydraulic-opening-closing down-hole-type double-hoisting-point arc-shaped gate. The hoisting method includes the following steps: 1, the arc-shaped gate is hoisted between gate piers on the two sides through a portal crane arranged on the upstream side of the top of an overflow dam; 2, after hoisting is completed, supporting arms on the two sides of an arc-shaped gate flap are hinged to the corresponding gate piers respectively; 3, hydraulic opening-closing machines are connected to the two ends of the arc-shaped gate flap respectively; 4, locking openings and arc-shaped gate grooves communicated with the locking holes are formed in the side walls of the gate piers and jointly form locking holes; 5, the arc-shaped gate flap descends to the positions of the locking holes, and one end of the arc-shaped gate flap is inserted into the locking holes; 6, the other end of the arc-shaped gate flap horizontally rotates in the upstream direction with the end, inserted into the locking holes, of the arc-shaped gate flap as the axis; 7, a chain block is adjusted to enable the arc-shaped gate flap to reach the preset installation position along the arc-shaped gate grooves. By means of the hoisting method, rapid hoisting of the arc-shaped gate is achieved, and the hoisting method is safe and feasible.

Description

technical field [0001] The invention relates to a hoisting method, in particular to a hoisting method for a submerged double-suspension-point arc gate for hydraulic opening and closing. Background technique [0002] With the development of China's economy and society, China has gradually become the world's leading energy-consuming country, and electric energy, as a clean energy, occupies an increasing proportion in the energy consumption pattern. Hydropower is also making strides as one of the cleanest forms of electricity generation. As of the end of 2004, the country's developed hydropower installed capacity was 105.17 million kilowatts, with an annual power generation of 328 billion kWh, accounting for 23.8% of the country's total installed power capacity. Especially in recent years, the start of a large number of giant water conservancy and hydropower projects has further highlighted the country's emphasis on hydropower development. As an indispensable part of water co...
