Description

Technical Field

[0001] The utility model relates to the field of deep sea construction cleaning, in particular to a detachable steel casing outer wall attachment cleaning device. Background Art

[0002] When the time interval between the steel casing used in offshore pile foundation construction and the next construction process is more than 15 days, a large number of marine organisms will adhere to the surface of the steel casing stored in the seawater. In addition, in the deep sea environment, in order to ensure the verticality of the steel casing, the guide beam of the steel casing is often used to assist the construction of the pile foundation.

[0003] The traditional cleaning process uses an integrated steel casing cleaning device, but because the guide beam blocks the top of the steel casing, the traditional integrated steel casing cleaning device cannot work properly and the guide beam needs to be cut off before it can be used. This will increase the construction period, and cutting off the guide beam will cause great safety hazards to the project. Summary of the invention

[0004] The purpose of the utility model is to provide a detachable steel casing outer wall attachment cleaning device, which is installed on the steel casing outer wall below the guide beam, and realizes the cleaning work of the steel casing outer wall by moving up and down, which has the advantages of avoiding the process of cutting off the guide beam, greatly reducing the workload and working time of offshore operations, and reducing the safety hazards of the project.

[0005] The purpose of the utility model is achieved in this way:

[0006] A detachable device for cleaning attachments on the outer wall of a steel casing, characterized in that it is composed of a supporting ring body, a U-shaped wire brush, a lifting lug, a limiting plate, and a U-shaped brush card. A plurality of pairs of upper and lower double-layer holes are arranged on the side wall of the supporting ring body, and the limiting plate is horizontally fixed on the outer wall of the supporting ring body, in the middle of the upper and lower double-layer holes; reserved holes are arranged on the limiting plate, and a U-shaped wire brush is arranged in each hole. The U-shaped wire brush passes through the reserved hole, and the bottom of the U-shaped wire brush hooks the reserved hole. The two ends of the U-shaped wire brush pass through the upper hole and the lower hole from the outside of the supporting ring body and then extend into the inner side of the supporting ring body. Two U-shaped brush cards clamp the U-shaped wire brush from the upper and lower sides of the reserved hole of the limiting plate, respectively, to fix the U-shaped wire brush on the limiting plate; four lifting lugs are symmetrically arranged on the top of the supporting ring body, and the lifting lugs are connected to the hook of the crane through wire ropes.

[0007] The support ring body is composed of four arc-shaped support rings, each of which has an angle of 90°. The connection between two adjacent arc-shaped support rings is bolted through a connecting plate, and the four arc-shaped support rings are connected into a circular ring through the connecting plate.

[0008] A plurality of pairs of upper and lower double-layer holes are equidistantly arranged in a circular pattern.

[0009] The diameter of the reserved hole of the limiting plate and the diameter of the holes of the upper and lower layers of the supporting ring body are both 30 mm, the diameter of the U-shaped wire brush is 28 mm, and the length of a single U-shaped wire brush is 85 cm.

[0010] The wall thickness of the support ring is 5 cm and the curvature is 2 / 15.

[0011] The utility model is composed of a support ring body, a U-shaped wire brush, a lifting lug, a limit plate, and a U-shaped brush card. When in use, it is hoisted in blocks by a crane, assembled and bolted on the outer wall of the steel casing below the guide beam, so that the support ring body is sleeved on the outer wall of the steel casing, and the ends of the U-shaped wire brush are close to the outer wall of the steel casing. The hook of the crane is connected to the lifting lug at the top of the support ring body through a wire rope. The staff operates the crane to move the hook up and down, driving the support ring body to move up and down, and the U-shaped wire brush will continuously brush the outer wall of the steel casing, so that the attachments on the outer wall of the steel casing are continuously dropped, and the attachments on the outer wall of the steel casing are cleaned. After finishing the cleaning work of the outer wall of a steel casing, the U-shaped brush card, U-shaped wire brush, connecting plate, and arc-shaped support ring of the utility model can be disassembled in sequence, and then assembled on the outer wall of the next steel casing, and then the attachments on the outer wall of the next steel casing are cleaned.

[0012] Therefore, the utility model has the advantages of high efficiency in cleaning attachments on the outer wall of the steel casing, avoiding the process of cutting off the guide beam, greatly reducing the workload and working time of offshore operations, reducing engineering safety hazards, simple installation and disassembly, light and flexible, requiring fewer operators, and saving energy and reducing consumption.
