Description

Technical Field

[0001] The utility model belongs to the technical field of guardrails, and more specifically, it particularly relates to a production safety protection device. Background Art

[0002] To ensure the safety of the factory production environment and prevent accidents, guardrails are usually used to enclose dangerous areas, prevent people or objects from entering, and increase the safety of operations.

[0003] For example, the existing application number CN202320907674.4 discloses a safety guardrail, and the key points of its technical solution are as follows: It includes two columns, and several railings are arranged between the two columns; an anti-tipping component is arranged on both sides of the columns to prevent the columns and the railings from tipping over. By setting the columns, the staff places the columns and railings on one side of the foundation pit. Through the mutual cooperation of the support box, the column, the support block and the limiting column, the support box can be rotated to a suitable angle. Through the mutual cooperation of the nut, the second threaded column, the cover plate, the positioning column and the limiting groove, the limiting groove is separated from the second threaded column. Through the mutual cooperation of the spring, the support ring, the mounting column, the stop block, the connecting block, the insertion plate, the second threaded column and the moving hole, the tip of the insertion plate enters the soil and at the same time the insertion plate, the support box and the column form a stable support, avoiding the columns and railings from being blown down by the wind, achieving the anti-tipping effect on the columns and railings.

[0004] Based on the above, the existing guardrails are mostly integrated frame structures, which require a lot of space for transportation. And when installing them, the operators need to carry the guardrails to the construction site, splice and assemble multiple guardrails, and then position the assembled guardrails to the designated area of the factory building to achieve the enclosure protection of the dangerous areas in the factory, which not only affects the convenience of transporting the guardrail enclosures, but also affects the installation and positioning efficiency of the guardrails.
