Embodiment Construction

[0018] Such as figure 1 , figure 2 , image 3 As shown, the rapid maintenance method for the corroded plane gate of the hydropower station in this embodiment includes the following steps:

[0019] 1. Install the arc-shaped steel pipe frame movable workshop track at the opening of the gate slot 5 that needs to be overhauled;

[0020] 2. Locking of gate slot orifice:

[0021] Use chain hoist 8 and lifting equipment 10 equipped with the gate to lift the corroded plane gate 4 to be repaired to the opening of the gate slot 5, and use the gate lock beam 2 to lock the gate leaf to the opening of the gate slot;

[0022] 3. Desilting:

[0023] Use a high-pressure water gun to wash the sludge in the gate leaf that is locked in the gate slot orifice, thoroughly clean the gate, and return the sludge to the water to avoid secondary cleaning;

[0024] 4. Attachment removal:

[0025] Use an oxygen-acetylene gas cutting torch to cut off the attachment fasteners. When cutting, pay atten...

Abstract

The invention discloses a rapid repairing method of a corroded plane gate of a hydropower station. The rapid repairing method comprises the following steps that a temporary workshop rail is installed in agate slot hole opening of the gate to be repaired; the corroded plane gate to be repaired is hoisted to the hole opening for being locked; a curved steel tube frame movable workshop is installed; the curved steel tube frame movable workshop is hoisted to the gate hole opening for being locked, and dredging operation is carried out; cutting is conducted by using a plasma cutting machine, and after detaching a gate attachment, the curved steel tube frame movable workshop is moved to shield the gate; abrasive blasting operation is conducted for removing an old zinc layer; a gate water sealing seat plate vertically-moving machining device is used to conduct vertically-moving finish machining on a gate deformed water sealing seat plate; respraying is conducted on the gate by using semi-automatic electric arc thermal spraying zinc; accessories are installed after sealing by using inorganic spraying paint; and the gate is locked. The rapid repairing method solves repairing and restoring of all kinds of corroded plane gates of the hydropower station, and especially solves the construction problem of inconvenient transportation of plane gates of large section welding.

Description

Technical field: [0001] The present invention relates to a method for quickly overhauling various types of planar corrosion gates of any hydropower station, and in particular to a method for quickly overhauling corroded planar gates of hydropower stations that can solve the construction problem of inconvenient transportation of super-large internode welded planar gates. Background technique [0002] As we all know, the operation of hydropower station gates directly affects the operation of the hydropower station units. The normal operation of the gates is the key to ensuring the installation and operation of the power station, and the planar gates are almost indispensable in the layout and design of various power stations. Therefore, how to quickly overhaul the corroded planar gates Restoration technology has also become the primary consideration in the operation of various power stations. [0003] The maintenance period of the planar gates of hydropower stations is generall...
