Description

Technical Field

[0001] The embodiments of the present utility model belong to the technical field of workshop protection, and more specifically, relate to a lifting safety protection device. Background Art

[0002] During the mechanical processing in the workshop, there are various situations that may cause injury to personnel. The main manifestations include: (1) When the rotating chuck accidentally collides with the moving turning tool, it may cause the turning tool to be damaged or even broken, and the broken turning tool fragments may fly out at high speed, posing a threat to nearby workers; (2) The rotating chuck may entangle nearby clothing or other loose items, thereby causing serious physical injuries to the operator or other personnel; (3) The iron chips generated during the turning process may splash everywhere, causing injuries to the eyes or other exposed parts. Therefore, in order to ensure safety during the workshop production process, it is not only necessary to regularly maintain and inspect the equipment, but also necessary to reduce the risk of mechanical injury through physical protection measures such as setting safety baffles in dangerous areas.

[0003] In the prior art, a Chinese patent with the document number CN216446816U discloses a hardware protection net for a workshop, including a protection net body and a simple lock assembly. The protection net body includes a first support main rod, a second support main rod, and several support sub-rods. There is a protection door between the first support main rod and the second support main rod. There are baffles between the first support main rod and its adjacent support sub-rods, between the second support main rod and its adjacent support sub-rods, and between each adjacent pair of support sub-rods. The protection door and each baffle enclose a protection space. The simple lock assembly includes a simple lock male end and a simple lock female end. One end of the protection door is vertically hinged to the first support main rod, the simple lock male end is arranged at the other end of the protection door, and the simple lock female end is arranged on the second support main rod.

[0004] Although the hardware protection net of the Chinese patent with the document number CN216446816U can provide safety protection and prevent accidents, and is convenient for entry and exit, thus facilitating the maintenance and repair of equipment, it still does not solve some problems existing in the workshop safety protection device: (1) Using a wire mesh or the like as the main structure of the protection device, although it will provide good visibility through the mesh, in some occasions that require high visibility, the dense grid may cause visual interference, and for small objects flying out at high speed, the wire mesh may not be able to effectively intercept them; (2) The safety protection device needs to have a certain protection height, but after the workpiece processing is completed, the safety protection device with a fixed height will instead affect the subsequent lifting of the workpiece, increasing the complexity and time consumption of the operation and reducing work efficiency.
