[0029] In the workshop or warehouse of an enterprise, in order to avoid collision between workers and tractors and ensure the safety of workers, guardrails are usually used to separate the hoisting area used by tractors from the activity area for workers. During the production process, workers often need to pass through the hoisting area. Therefore, passages are usually opened on the guardrails to ensure the normal passage of workers. However, the passages opened by the existing guardrails are always open, and workers are very likely to mistakenly enter the hoisting area or enter the hoisting area without confirming the road conditions, which poses a safety risk. In addition, the existing guardrails are mostly steel guardrail structures, which are mainly supported by hollow circular tubes with larger diameters, and it is difficult to install sliding doors on such guardrails.
