Description

Technical Field

[0001] This utility model belongs to the field of cooling tower technology, specifically an external security platform for a composite flow cooling tower. Background Technology

[0002] Cooling towers are commonly used equipment in industrial production to cool hot water for reuse. Traditional cooling tower safety platforms are typically installed at the top of the tower, requiring maintenance personnel to climb to the top via a side ladder. However, this design has the following problems:

[0003] 1. The increased overall height of the cooling tower leads to a more complex structure and higher costs;

[0004] 2. The space at the top of the tower is limited, and there are usually not enough walkways or maintenance platforms, making it difficult for maintenance personnel to move around and operate.

[0005] 3. Maintenance personnel need to climb to the top of the tower, which poses certain safety hazards.

[0006] To address the aforementioned issues, this invention proposes an external security platform installed on the side of a cooling tower. This platform reduces the overall height of the cooling tower and provides sufficient space for maintenance personnel, thereby improving the safety and convenience of maintenance. Utility Model Content

[0007] To address the above problems, this utility model provides an external security platform for composite flow cooling towers. By installing the security platform on the side of the cooling tower, the overall height of the cooling tower is reduced, while providing a safe and convenient maintenance environment for maintenance personnel.

[0020] Several longitudinally placed third support beams;

[0021] The platform treads are erected above the first support beam, the second support beam, and the third support beam.

[0022] As a further improvement to the above solution, the first support beam, the second support beam and the third support beam are all sheet metal parts with inward bending on both sides and a C-shaped cross-section.

[0023] As a further improvement to the above solution, the platform tread is a flat plate with several drainage holes to prevent rainwater from accumulating on the top of the platform.

[0024] As a further improvement to the above solution, the fence assembly is composed of inwardly bent sheet metal parts and is bolted together to surround the maintenance platform assembly.

[0025] As a further improvement to the above solution, the platform support beam is welded from a round steel bar and angle steel at both ends, and is connected between the fence assembly and the cooling tower body to form a stable triangular support structure.

[0026] As a further improvement to the above solution, the maintenance platform component can be assembled from multiple sets to extend the length of the maintenance platform.

[0027] As a further improvement to the above solution, the inclination angle of the platform support beam is adjustable, which can be used to lengthen or shorten the width of the maintenance platform.

[0028] The external security platform of this utility model has the following advantages:

[0029] 1. The security platform is installed on the side of the cooling tower, reducing the overall height of the cooling tower;

[0030] 2. Maintenance personnel do not need to climb to the top of the tower, making maintenance more convenient and safer;

[0031] 3. The platform has a stable structure and can withstand large gravity, ensuring the safety of the maintenance process;

[0032] 4. The platform can be spliced ​​and adjusted to meet the needs of cooling towers of different sizes. Attached Figure Description
