Hoisting method used for hydraulic-opening-closing down-hole-type double-hoisting-point arc-shaped gate
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.
