Description

Technical Field

[0001] This invention is a multi-functional construction safety protection device, belonging to the field of construction safety technology. Background Technology

[0002] During construction, safety protection devices are core equipment for ensuring the personal safety of construction workers and preventing materials from falling. They are widely used in dangerous areas such as building edges, foundation pits, and work passages. Existing construction safety protection devices suffer from low installation and dismantling efficiency. Traditional protective devices often use bolts or welding to fix the guardrails and posts, requiring repeated adjustments with tools during assembly and disassembly piece by piece, making them unsuitable for the frequent setup and relocation needs of construction sites. Furthermore, their stability is insufficient; most devices rely solely on simple ballast on the bottom plate or shallow insertion of rods into the ground, making them prone to tipping over or shifting under soft ground or external impacts. Especially in complex terrains such as foundation pits and slopes, the anchoring effect is poor, leading to loosening after long-term use and even guardrail detachment, posing safety hazards. Summary of the Invention

[0003] In view of the shortcomings of existing technologies, the purpose of this invention is to provide a multi-functional building construction safety protection device.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0005] A multi-functional construction safety protection device includes columns and guardrails. The guardrails are movably connected between each pair of columns. The guardrails have horizontal bars on both sides for insertion into the columns. The outer wall of the columns has insertion holes for the horizontal bars to be inserted.

[0006] The bottom of the column is provided with a base plate, and the base plate is provided with a reinforcement mechanism for anchoring;

[0007] The column is equipped with a limiting mechanism for limiting the position of the crossbar.

[0008] The limiting mechanism includes a mounting plate located inside the column and between the two sets of crossbars. The mounting plate is provided with a sliding block 1 and a sliding block 2, which are slidably connected. Each of the sliding block 1 and the sliding block 2 has a limiting rod that passes through the crossbar on one side.

[0009] Preferably, the crossbar has a through hole for the limiting rod to pass through, and each of the slider one and slider two has a toothed plate on the side that is close to each other. The mounting plate is rotatably connected between slider one and slider two and has gears that mesh with the two sets of toothed plates.

[0010] Preferably, the gear is movably connected to the column via a rotating shaft, a worm gear is sleeved on the rotating shaft, and a worm is rotatably connected to the column, meshing with the worm gear.

[0011] Preferably, one end of the worm gear extends to the outside of the column and is provided with a rotating handle, and the mounting plate is provided with a sliding groove for sliding the slider one and the slider two.

[0012] Preferably, the reinforcement mechanism includes a post that extends through the base plate. The post is hollow and has an outwardly extending rod inside. A foot pedal is provided on one side of the top of the post.

[0013] Preferably, the insert has a connecting block that is horizontally arranged with the insert rod, and the top of the connecting block has a slide corresponding to the position of the insert rod. A matching moving block is slidably connected in the slide, and a connecting rod connected to the insert rod is provided on one side of the moving block.

[0014] Preferably, the top of the connecting block is provided with a rotatable turntable, and the bottom of the turntable is uniformly surrounded by arc-shaped rods connected to the moving block.

[0015] Preferably, the arc-shaped rod is movably connected to the turntable and the moving block respectively via pins, and the number of the insert rods is four sets.

[0016] Preferably, the turntable is movably connected to the connecting block via a fixed shaft. A second worm gear is sleeved on the fixed shaft, and a second worm is provided on one side of the second worm gear to mesh with it. One end of the second worm extends to the outside of the insertion post and is provided with a knob.

[0017] Preferably, the outer wall of the insertion post is provided with a travel hole for the insertion rod to move outward.

[0018] The beneficial effects of this invention are:

[0019] The guardrail connects to the posts via interlocking holes on the horizontal bars. The automated locking design of the limiting mechanism eliminates the need for complex tools; simply turning the handle allows for easy locking or unlocking of the horizontal bars. Assembly and disassembly can be completed quickly by a single person, adapting to the needs of frequent relocation on construction sites. Stepping on the pedal allows for quick insertion of the posts into the ground, and turning the knob drives four sets of posts to extend laterally and embed themselves in the soil, significantly increasing the contact area and friction with the ground. Even on soft ground or under external impact, this effectively prevents the device from tipping over or shifting, significantly improving anchoring stability. The limiting mechanism, through the meshing of gears and toothed plates, drives slider one and slider two to slide synchronously in opposite directions, allowing the limiting rod to precisely pass through the through hole of the horizontal bar, achieving a rigid connection between the guardrail and the post. Combined with the self-locking characteristics of worm gear one and worm one, it prevents accidental loosening of the limiting rod, ensuring a secure guardrail connection and eliminating the risk of detachment.
