Problems solved by technology

[0003] Using the above method to overhaul the cabin door of the ship lift has the following defects: (1) Due to the unsatisfactory leakage of the cabin door after the water-stop maintenance Foreseeability, after the inspection of the ship door is completed, it is found that the water is leaking, and it is necessary to repeatedly perform the work of draining the ship room, filling water, building scaffolding, and dismantling the scaffolding, which consumes a lot of manpower and material resources, and will increase the construction cost. The cabin is frequently drained and filled with water, which affects the structural stability of the entire cabin; (2) During the maintenance of the cabin door, it is necessary to drain the cabin, build scaffolding, remove the scaffolding, fill the cabin with water, etc. The process and maintenance time are long, which seriously affects the navigation efficiency of the ship lift; (3) When building the maintenance platform of the cabin door, it is necessary to weld and implant steel pipes on the bottom of the cabin, the side wall, and the cabin door to ensure the safety and stability of the scaffold. The structure of the cabin and the cabin door is damaged, which affects the service life of the structure
[0005] Firstly, usually the first working door of the ship lift lock is a flat door, while the cabin door is an arc door, and there is a big difference in the opening and closing and working methods of the two. Generally, the opening and closing of the flat door is vertical lifting or horizontal pushing and pulling, while the arc door generally runs around the arc track, and the layout position and environment of the two are quite different, so there are differences in the maintenance methods and maintenance platforms of the two. Therefore, the patent with the application number "202010974377.2" cannot be applied to the maintenance method of the ship lift cabin door described in this patent. However, this patent has successfully solved the rapid The technical problem of maintenance; the second is that the fast maintenance method of the ship lift cabin door described in the present invention can realize the maintenance of the cabin door without draining the cabin, and the patent with the application number "202010974377. Neither the quick repair method of the compartment door nor the repair platform are involved

Embodiment 1

[0076] When the upstream water level is 175m, take the maintenance of the upstream cabin door as an example to describe the quick maintenance method of the cabin door of the ship lift.

[0077] Step 1): Check that the water seal at the upstream butt joint sealing frame of the ship compartment is reliable and no defects are found. When the upstream water level is 175m, place 8 sections (3.5 meters high each) on the upper lock head to overhaul the stacking beam door and a section (high 12m) inspection door, the elevation of the bottom sill of the upstream channel is 141m, the elevation of the top of the upstream inspection door is 181m, the highest water level may appear in the upstream of 175m, and the top elevation of the upstream inspection door exceeds the maximum water level of the upstream by 6 meters, which can prevent the upstream water from overflowing the inspection block Accidents caused by water gates;

[0078] Step 2): Run the ship lift cabin to the upstream docking...

Embodiment 2

[0091] Take the downstream cabin door maintenance when the downstream water level is 73.8 meters as an example to describe the quick maintenance method of the ship lift cabin door.

[0092] Step 1): Check that the water seal at the downstream docking sealing frame of the ship compartment is reliable and no defects are found. When the downstream water level is 73.8m, drop the first 8 sections of the lock (each section is 3.25m high) to overhaul the stacking beam doors, and the bottom sill of the downstream channel If the elevation is 58 meters, the elevation of the top of the downstream inspection door is 84m, and the highest water level in the downstream may be 73.8m. The elevation of the top of the downstream inspection door exceeds the maximum water level of the downstream by 10.2 meters, which can prevent accidents caused by the downstream flooding over the inspection water retaining door;

[0093] Step 2): Run the ship lift cabin to the downstream docking position, stop the...

Abstract

The invention relates to a rapid maintenance method and a maintenance platform for a ship compartment door of a ship lift, and provides a rapid maintenance method for the ship compartment door under the state that a ship compartment is not drained in order to overcome the defects that the maintenance of the ship compartment door of the ship lift is long in time consumption, consumes a large amount of manpower and material resources and the like. The platform used for achieving the rapid maintenance method of the ship compartment door comprises a maintenance platform body, a maintenance platform opening and closing device, a maintenance platform locking device and a guiding and buffering device, the maintenance platform body can rotate around a supporting hinge in a vertical plane through the opening and closing device, and the maintenance platform body is erected and locked through the locking device in the non-maintenance state. According to the rapid maintenance method and maintenance platform for the ship compartment door of the ship lift, the construction workload can be reduced to a great extent, and the ship compartment and the ship compartment door structure are protected against damage.

Description

technical field [0001] The invention relates to a construction method for maintenance of navigable building equipment and a supporting construction platform, in particular to a method for quick maintenance of a compartment door of a ship lift and a maintenance platform. Background technique [0002] The ship compartment door is a water blocking device for the ship lift compartment. When the ship lift is moving up and down, the ship compartment door is arranged upstream and downstream of the ship compartment to block water to prevent water leakage in the compartment. When the compartment is docked with the lock head, the compartment is opened. The door connects the cabin with the upstream and downstream channels to enter and exit the ship. During the maintenance of the cabin door, due to the layout of the equipment in the cabin, there is no water blocking door for the maintenance of the cabin. Therefore, it is necessary to drain the water in the cabin and then build scaffoldi...
