Description

Technical Field

[0001] The utility model relates to the technical field of equipment safety protection, in particular to an assembled guardrail. Background Art

[0002] Cooling towers are essential equipment in industrial production. Usually, the top of the cooling tower is very high from the ground. In order to ensure the safety of users and maintenance personnel, the top of the cooling tower should be equipped with a safety guardrail in accordance with relevant national standards, and the relevant parameters of the guardrail should comply with national standards.

[0003] The traditional guardrail type is a welded connection between the column and the crossbar. The bottom of the supporting column of the guardrail is welded with a fixing plate for connecting to the cooling tower. The advantage of the welded guardrail is that the connection is firm. The disadvantage is that the welding of the guardrail requires professional technicians to operate. Since the size of the equipment is usually large, the error of the structure after the guardrail is welded is also large. Once the formation is completed, the rectification process is complicated. For the sake of aesthetics, the weld needs to be processed after welding, and the process requirements are high. After the guardrail is welded, the guardrail becomes a whole, which is difficult to remove later. Utility Model Content
