Description

Technical Field

[0001] The utility model relates to the technical field of mechanical operation enclosures, in particular to a safety enclosure for heavy mechanical operations. Background Art

[0002] Tower crane generally refers to tower crane, which is the most commonly used lifting equipment on construction sites. It is used to lift construction materials such as steel bars, wooden slats, concrete, steel pipes, etc. It is an indispensable equipment on construction sites and also a heavy machinery. Fences are often installed at the bottom of the tower crane to prevent strangers from climbing onto the tower crane.

[0003] The prior art discloses a safety enclosure for a tower crane, with announcement number CN220056145U, comprising a safety fence body and a base. Alarm lights are fixedly connected to both sides of the top back of the safety fence body. A mounting slot is provided inside the base, and an alarm is fixedly connected to the rear side of the inner wall of the mounting slot. A fixing plate is fixedly connected to the bottom back of the safety fence body, and a power supply assembly is fixedly connected to the top of the fixing plate. A vibration detector is provided on the back of the safety fence body. The device, by providing a vibration detector, emits an electrical signal to activate the alarm lights and alarm when it detects that the safety fence body is damaged and vibrates violently. This solves the problem that fences only have a blocking effect, are single-functional, and lack an alarm structure. If an intruder violently damages the safety fence and enters, the user may not notice, allowing unauthorized persons to board the tower crane. This device achieves the desired alarm prompt effect.

[0004] The above-mentioned safety fence for heavy machinery operations is equipped with a vibration detector. When the vibration detector detects that the safety fence body is damaged and produces violent vibrations, it will send an electrical signal to turn on the alarm light and the alarm, thereby solving the problem that the fence only has a blocking effect. However, the above-mentioned device can only be set up in a single group, and the anti-slip buffer component set at the bottom is insufficient. There is no pressure detection device, and the vibration detection component is prone to misdetection, which is not effective during use and needs to be improved. Utility Model Content
