Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering, in particular to a protective device used in municipal engineering. Background Art

[0002] At present, in order to protect the safety of municipal engineering personnel and equipment, protective facilities are set up around the construction site. These facilities include railings, guardrails, guardrails, nets, shields, etc., which are used to prevent people and objects from falling from heights and prevent splashing materials from injuring people. At the municipal engineering construction site, protective devices are indispensable and must be set up in accordance with regulations and kept intact to ensure construction safety.

[0003] The authorization announcement number in the prior art is: CN219528632U, and the name is a protective device for municipal engineering, including: a base, a connecting frame, a top plate, a concave block, a convex block and a protective assembly. The top of the base is fixedly connected to two connecting frames, the tops of the two connecting frames are fixedly connected to the top plates, the outer surface of the left connecting frame is fixedly connected to the concave block, and the outer surface of the right connecting frame is fixedly connected to the convex block. A protective assembly is provided on the top of the base. The patent is that the two guardrails can be fixed and spliced ​​by inserting a fixing rod after splicing the convex block and the concave block. The two connecting frames are used to fix the base and the top plate. When the impact force is applied, the protective pad will drive the rotating rod to rotate horizontally, thereby buffering the impact force once. At the same time, the rotating rod will move backward and perform a second buffering through the contraction of the spring. The protective block can protect the spring from being damaged. The elastic buffer layer inside the protective pad can also reduce part of the impact force. The advantage of this patent is that the two guardrails can be fixed and spliced ​​by inserting a fixing rod after splicing the convex block and the concave block, so that the two guardrails can be firmly connected together, thereby improving the protective effect. The two connecting frames are used to fix the base and the top plate, making the entire protective device more stable and firm. When the impact force is applied, the protective pad will drive the rotating rod to rotate horizontally, thereby buffering the impact force once, thereby reducing the impact force on the equipment and personnel. The rotating rod will move backward and perform a second buffering through the contraction of the spring. The protective block can protect the spring from being damaged. The elastic buffer layer inside the protective pad can also reduce part of the impact force, thereby improving the protective effect.

[0004] However, when installing this patent, the operator needs to manually connect the protrusions and concave blocks to complete the installation. At the same time, it is also difficult to store the equipment after disassembly, which makes the operation more cumbersome for the operator. When using this patent, if the equipment is damaged on a road section without cameras, law enforcement officers cannot retrieve effective information, and the effect is relatively simple and has poor practicality.
