Abstract

The invention discloses a ship lock reverse arc-shaped valve top water stop installation structure and a transformation construction technology. The ship lock reverse arc-shaped valve top water stop mounting structure comprises a reverse radial gate, a gate body lifting lug is fixedly mounted on the reverse radial gate, a lifting rod is hinged to the gate body lifting lug, a water stop base plate is arranged on the edge of the top of the reverse radial gate, and front row fixing screw holes penetrating through the front row of the water stop base plate and the reverse radial gate are machined in the front row of the water stop base plate and the reverse radial gate; rear-row fixing screw holes are formed in the rear row of the water stop base plate and the reverse radial gate; the top of the water stop base plate is fixedly provided with a top water stop through a top water stop pressing plate; the end head of the top water stop is matched with a lintel water stop base plate; and a plurality of process holes are formed in the upstream face guide plate of the reverse radial gate. By adopting the structure, the installation convenience and reliability of the reverse radial gate top water stop are improved, the repair work of invalid screw holes of the reverse radial gate top water stop base plate is reduced, the replacement and maintenance efficiency of the reverse radial gate top water stop is improved, and the service life of the reverse radial gate top water stop is prolonged.

Description

technical field

[0001] The invention relates to the field of maintenance of large-scale ship lock valves, in particular to a water-stop installation structure at the top of a reverse arc valve of a ship lock and a reconstruction construction process. Background technique

[0002] The anti-arc door is an important operating equipment of the ship lock, and the lock chamber is filled and discharged through the opening of the anti-arc door. The anti-arc gate is opened and closed by dynamic water when the water head is high, the operation is frequent, the working environment is harsh, the structure is stressed, and the failure rate is relatively high compared with other equipment in the ship lock. The common faults of the anti-arc door mainly include damage to the water stop, deformation of the water stop pressure plate, failure of the threaded hole of the door body water-stop seat plate, damage to the bolt thread, series movement of the joint door shaft, wear of the joint door s...
