Description

Technical Field

[0001] This utility model relates to the technical field of safety devices for construction sites, specifically to a device for preventing personnel from falling through pre-reserved holes in the foundation of a cabinet. Background Technology

[0002] Currently, before the electrical and instrument panels are installed, the pre-reserved holes in the panel foundation are protected by setting up warning tape and laying temporary wooden boards in the holes. If personnel accidentally enter, a fall could occur if the temporary wooden boards break. Removing these temporary protective measures before panel installation is time-consuming and labor-intensive, creating a gap in protection during the installation process. Utility Model Content

[0003] The purpose of this utility model is to solve the problem that the existing method of protecting the pre-reserved holes in the base of the cabinet is inconvenient to open and close and poses a safety hazard.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A device for preventing personnel from falling through a pre-reserved hole in the foundation of a cabinet, characterized in that it includes a retractable fall arrestor for sealing the pre-reserved hole and a drive device for retracting and extending the fall arrestor.

[0006] The drive device includes a central shaft protective cover and an electric motor for providing power to the fall arrestor. The central shaft protective cover is installed on the floor on one side of the reserved hole. The central shaft is rotatably connected inside the central shaft protective cover. The output end of the electric motor is driven and connected to the central shaft. The electric motor is installed on one side wall of the central shaft protective cover.

[0007] The fall arrestor is fixed at one end facing the reserved hole, and the other end of the fall arrestor is fixed on the central axis. The fall arrestor is made of several parallelogram-shaped fall arrestor panels hinged together.

[0008] A further improvement is that the fixing device is a right-angled locking block, which engages with the channel steel on the other side of the pre-drilled hole after the fall arrestor plate has been deployed into place. This prevents the fall arrestor plate from retracting unexpectedly.

[0009] A further improvement is that the fall protection curtain is a metal fall protection curtain.

[0010] A further improvement is that a fixing connecting strip is fixedly connected to one side of the central shaft protective cover, and the central shaft protective cover is fixedly connected to the ground on one side of the reserved hole through the fixing connecting strip.

[0011] A further improvement is that the fixing connecting strip has several bolt holes, and the fixing connecting strip is fixedly connected to the ground on one side of the reserved hole by bolts engaging with the bolt holes.

[0012] A further improvement is that the motor is mounted on the side wall of the central shaft protective cover via a motor mounting bracket.

[0013] A further improvement is that a motor protection plate is provided on the side of the motor facing the reserved hole, and the motor protection plate is fixedly connected to the motor fixing bracket.

[0014] A further improvement is that a protective plate is installed on the side of the central shaft protective cover facing the reserved hole.

[0015] Compared with existing technologies, the above technical solution has the following advantages:

[0016] Compared to existing protective methods such as setting up warning tapes and laying wooden boards, fall arresters are made of parallelogram-shaped fall arrester curtains that are hinged together. They are driven by an electric motor to extend and retract, making them flexible and convenient to deploy and retract. The metal material makes them more stable, which can significantly improve the safety and ease of deployment and retraction. After the fall arrester is extended into place, the end fixing device is used to fix the fall arrester to the channel steel, which can prevent the protective plate from shrinking unexpectedly, making it safer.
