Embodiment 1

[0029] Such as figure 1 , figure 2 As shown, a method for hoisting a down-the-hole double-lift point arc gate for hydraulic opening and closing includes the following steps: Step 1: Use a gate crane arranged on the upstream side of the overflow dam crest to hoist the arc gate 1 to Between the gate piers 2 on both sides; Step 2: After the hoisting is completed, hinge the arms 4 on both sides of the arc-shaped door leaf 3 to the corresponding pier 2; Step 3: On the two sides of the arc-shaped door leaf 3 The ends are respectively connected to the hydraulic hoist 5; Step 4: Open a locking hole 6 on the side wall of the pier 2 and an arc-shaped door slot 7 connected to the locking hole 6; the locking hole 6 and the arc-shaped door slot 7 together form a locking hole ; Step 5: Lower the curved door leaf 3 to the position of the locking hole, and extend one end of the curved door leaf 3 into the locking hole; Step 6: The other end of the curved door leaf 3 extends into the arc of th...

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 of a down-the-hole type double hoisting point arc gate used 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 consumption country, and electric energy, as a clean energy source, accounts for an increasing proportion of the energy consumption pattern. As one of the cleanest forms of electricity generation, hydropower has also made great progress. As of the end of 2004, the country has developed an installed hydropower capacity of 105.17 million kilowatts, with an annual power generation capacity of 328 billion kWh, accounting for 23.8% of the country’s total installed capacity. In particular, the start of a large number of giant water conservancy and hydropower projects in recent years has highlighted the country's emphasis on hydropower development. As an in...
