Description

Pothole environment access safety guard

This creation is a safety protection device for the entry and exit of the pothole environment, which is installed in the opening of the pothole environment and prevents the safety protection device for personnel or foreign objects from being mistaken into the pothole.

In the pothole environment, the opening of the pothole is set on the ground. Usually, a cover is provided in the opening of the pothole to close the opening to prevent people from falling into the pothole. If the person wants to enter the pothole to clean up the oil or water When replacing control lines, trunking and pipelines, the cover will be picked up to expose the opening of the pothole to provide personnel access. After the cover is picked up, additional warning cones, railings or rails need to be placed on the ground. A warning cord is placed around the opening of the pothole to alert other personnel and prevent it from falling into the pothole.

Among them, the safety objects such as warning cones, railings or warning cords are mobile objects. When not in use, a space is needed to accommodate the safety objects. When it is necessary to enter and exit the pit, the safety objects are taken out and placed. After the work done in the pit is completed, the safety objects are stored and the cover is closed to close the opening of the pothole, and the storage and access of the safety objects are not convenient and occupy the storage space.

In addition, safety objects such as warning cones, railings or warning cords are mobile objects. People on the ground may accidentally collide with and offset the safety objects when walking. If the offset is large, it may fall into the pothole and hurt the pit. In the hole People in the industry, so mobile security objects can be moved at will to reduce the security of use.

The main purpose of this creation is to provide a safety protection device for the entry and exit of the pothole environment, thereby improving the problem that the existing mobile safety objects are difficult to store and the safety is not good.
