A falling prevention device for segmental beam modification frame installation

Abstract

This invention discloses a fall arrest device for installing a segmental beam decorative frame. In this invention, an upper welding plate penetrates the upper surface of the outer buffer side plate, and a supporting lower rod is welded to the top of the upper welding plate. An upper mounting base plate is provided on the upper surface of the supporting lower rod, and the upper mounting base plate is connected to the side of the decorative frame body. When installing the fall arrest net, it can be installed using magnetic adsorption protrusions and reinforcing threaded holes. During installation, the magnetic adsorption protrusions inside the fall arrest net mounting side plates on both sides of the fall arrest net are aligned with the reinforcing threaded holes. Then, the magnetic adsorption protrusions and the surface where the magnetic plate is placed will attract each other, thereby fixing the fall arrest net to the outer surface where the magnetic plate is placed. When the surface of the fall arrest net needs cleaning, the fall arrest net mounting side plates can be directly removed for cleaning, thus improving the glassiness of the fall arrest net mounting side plates during use.

Description

Technical Field

[0001] This invention belongs to the field of anti-fall technology for decorative frame installation, specifically an anti-fall device for installing segmental beam decorative frames. Background Technology

[0002] The precast segmental beam continuous rigid frame bridge is laid overhead along the existing national highway. Construction must not disrupt the existing traffic flow on the highway. Its main beam consists of cast-in-place blocks atop the central piers, precast segments, post-cast strips on the tops of the precast segments at the side piers, wet joints, simply supported prestressed ends, continuous prestressed box girder, and longitudinal prestressed sections at the pier tops. During the installation of the segmental beams, personnel working at height must undergo regular physical examinations. Those unsuitable for working at heights are prohibited from this work. Workers must wear safety belts, helmets, and non-slip shoes. All personnel entering the construction site must wear safety helmets and appropriate personal protective equipment or safety belts. Workers are prohibited from wearing slippers, high heels, hard-soled slippery shoes, or skirts on the construction site. Ladders, workbenches, guardrails, safety nets, etc., erected for construction must be sturdy and reliable, and can only be used after passing inspection. Tools and materials used in the work should be placed securely, and small tools should be kept in tool bags at all times. Throwing tools is strictly prohibited when passing them up or down. Workers should attach their safety belts to the horizontal braces on both sides of the scaffolding, ensuring a high attachment point and low usage. Additionally, fall arrestors must be installed during the installation process.

[0003] However, in the process of using common installation devices, when the fall protection device is hit by a falling heavy object, the surface of the fall protection device will be damaged by the impact, thus affecting its safety and durability during use. Summary of the Invention

[0004] The purpose of this invention is to provide a fall prevention device for installing segmental beam decoration frames in order to solve the problems mentioned above.

[0005] The technical solution adopted in this invention is as follows: A fall arrest device for installing a segmental beam decoration frame includes a decoration frame body. A base mounting plate is welded to both sides of the bottom of the decoration frame body. An outer fall arrest frame reinforcement base is fixedly connected to one side of the base mounting plate opposite to the decoration frame body. A fall arrest device is installed inside the outer fall arrest frame reinforcement base. Outer buffer side plates are installed on both sides of the fall arrest device. A central limiting plate is movably installed inside the outer buffer side plates. An upper mounting rod is installed on the upper surface of the central limiting plate. A top mounting block is installed at the top of the upper mounting rod, and an upper welding plate is installed at the top of the top mounting block. The upper welding plate penetrates the upper surface of the outer buffer side plates, and a lower support rod is welded to the top of the upper welding plate. An upper mounting plate is installed on the upper surface of the lower support rod, and the upper mounting plate is connected to the side of the decoration frame body.

[0006] In a preferred embodiment, damping rods are provided on the inner walls of the upper and lower sides of the outer buffer side plate, and a buffer spring is sleeved on the outer wall of the damping rod above the central limiting plate.

[0007] In a preferred embodiment, a buffer damper is provided at the bottom end of the damping rod, and the lower surface of the buffer damper is fixedly connected to the bottom inner wall of the outer buffer side plate.

[0008] In a preferred embodiment, a vertical locking strip is longitudinally fixedly connected to one side surface of the external fall arrester reinforcement base, and a horizontal locking strip is transversely fixedly connected to one side surface of the external fall arrester reinforcement base.

[0009] In a preferred embodiment, the outer fall arrestor reinforcement base has a horizontal connecting groove on the side surface opposite to the horizontal and vertical connecting strips, and the size of the connecting groove is adapted to the horizontal connecting strip. The outer fall arrestor reinforcement base has a vertical connecting groove on the side surface opposite to the horizontal and vertical connecting strips, and the size of the connecting groove is adapted to the vertical connecting strip.

[0010] In a preferred embodiment, the upper surface of the outer buffer side plate is provided with a fixing groove, and the fixing groove abuts against the outer side wall of the upper welding plate.

[0011] In a preferred embodiment, the upper surface of the fall arrestor is welded with a plurality of magnetic plates at intervals. The upper surface of the magnetic plates is provided with reinforcing threaded holes on both sides. The interior of the reinforcing threaded holes is connected to the fall arrestor installation side plate by magnetic adsorption. The upper surface of the outermost magnetic plate is welded with a side baffle, and the side baffle is connected to the two ends of the outer buffer side plate.

[0012] In a preferred embodiment, a fall protection net is fixedly connected between the two fall protection net mounting side plates. The side plate of the fall protection net mounting side plate near the magnetic plate is provided with a plurality of magnetic adsorption protrusions, and the size of the magnetic adsorption protrusions is adapted to the reinforcing threaded holes.

[0013] In a preferred embodiment, a fixed top plate is provided at the top of the lower support rod, and the two sides of the fixed top plate are threadedly connected to the inner surface of the upper mounting base plate through threaded holes.

[0014] In a preferred embodiment, the two sides of the horizontal locking strip are bonded with resistance pads, and the resistance pads abut against the two side surfaces of the connecting horizontal locking groove or the connecting vertical locking groove.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0016] 1. In this invention, when installing the fall arrest net, it can be installed using magnetic adsorption protrusions and reinforcing threaded holes. During installation, the magnetic adsorption protrusions inside the side plates of the fall arrest net on both sides are aligned with the reinforcing threaded holes. Then, the magnetic adsorption protrusions and the surface where the magnetic plate is placed will attract each other, thereby fixing the fall arrest net to the outer surface where the magnetic plate is placed. When it is necessary to clean the surface of the fall arrest net, the side plates can be removed directly for cleaning, thereby improving the glassiness of the side plates during use.

[0017] 2. In this invention, when the magnetic plate and the upper surface of the fall arrestor net on the inner side of the outer buffer side plate are impacted, the magnetic plate will be displaced downwards, causing the outer buffer side plate to stretch the buffer springs on both sides of the upper surface of the central limiting plate. This causes the buffer springs to undergo elastic deformation, which, combined with the damping effect of the damper at the bottom of the damping rod, can buffer the vibration amplitude, thereby improving the overall impact resistance and service life of the outer buffer side plate during use.

[0018] 3. In this invention, when multiple external fall arrestor reinforcement bases need to be connected, a single decorative frame body can be taken out, and the horizontal and vertical locking strips on one side of the external fall arrestor reinforcement base can be aligned with the interior of the connecting horizontal and vertical locking slots on the other side of the external fall arrestor reinforcement base. Then, the resistance pads on both sides of the horizontal locking strips abut against the inner wall of the connecting horizontal locking slot, so that the resistance pads will generate friction and resistance with the interior of the connecting horizontal locking slot, thereby generating frictional resistance between multiple external fall arrestor reinforcement bases, so that the external fall arrestor reinforcement bases are less likely to fall off, and increasing the firmness and stability of the connection between multiple external fall arrestor reinforcement bases.

A top mounting block 18 is installed at the top of the upper mounting rod 26, and an upper welding plate 19 is installed at the top of the top mounting block 18. The upper welding plate 19 penetrates the upper surface of the outer buffer side plate 2, and a lower support rod 5 is welded to the top of the upper welding plate 19. An upper mounting base 3 is installed on the upper surface of the lower support rod 5, and the upper mounting base 3 is connected to the side of the trimming frame body 1.

[0031] Damping rods 21 are provided on the inner walls of the upper and lower sides of the outer buffer side plate 2, and buffer springs 20 are sleeved on the outer wall of the damping rods 21 above the central limiting plate 17.

[0032] A buffer damper 22 is provided at the bottom end of the damping rod 21, and the lower surface of the buffer damper 22 is fixedly connected to the bottom inner wall of the outer buffer side plate 2.

[0033] A vertical locking strip 7 is longitudinally fixedly connected to one side surface of the external fall arrester reinforcement base 8, and a horizontal locking strip 6 is transversely fixedly connected to one side surface of the external fall arrester reinforcement base 8.

[0034] The outer fall arrestor reinforcement base 8 has a horizontal connecting groove 23 on the side surface opposite to the horizontal connecting strip 6 and the vertical connecting strip 7, and the size of the connecting groove 23 is adapted to the horizontal connecting strip 6. The outer fall arrestor reinforcement base 8 has a vertical connecting groove 25 on the side surface opposite to the horizontal connecting strip 6 and the vertical connecting strip 7, and the size of the connecting groove 25 is adapted to the vertical connecting strip 7.

[0035] The upper surface of the outer buffer side plate 2 is provided with a fixing groove 10, and the fixing groove 10 abuts against the outer side wall of the upper welding plate 19.

[0036] Multiple magnetic plates 11 are welded at intervals on the upper surface of the fall arrestor. Reinforcing threaded holes 12 are opened on both sides of the upper surface of the magnetic plates 11. The interior of the reinforcing threaded holes 12 is connected to the fall arrestor net mounting side plate 15 by magnetic adsorption. A side baffle 13 is welded on the upper surface of the outermost magnetic plate 11, and the side baffle 13 is connected to the two ends of the outer buffer side plate 2.

[0037] A fall protection net 14 is fixedly connected between two fall protection net mounting side plates 15. Multiple magnetic adsorption protrusions 16 are provided on the side surface of the fall protection net mounting side plate 15 near the magnetic plate 11, and the size of the magnetic adsorption protrusions 16 is adapted to the reinforcing threaded hole 12.

[0038] The top of the supporting rod 5 is provided with a fixed top plate 4, and the two sides of the fixed top plate 4 are threadedly connected to the inner surface of the upper mounting base plate 3 through threaded holes.

[0039] The two sides of the horizontal locking strip 6 are bonded with resistance pads 24, and the resistance pads 24 abut against the two sides of the connecting horizontal locking groove 23 or the connecting vertical locking groove 25.

[0040] In this invention, when installing the fall arrest net 14, it can be installed using the magnetic adsorption protrusions 16 and the reinforcing threaded holes 12. During installation, the magnetic adsorption protrusions 16 inside the fall arrest net mounting side plates 15 on both sides of the fall arrest net 14 are aligned with the reinforcing threaded holes 12. Then, the magnetic adsorption protrusions 16 and the surface of the magnetic plate 11 will attract each other, thereby fixing the fall arrest net 14 to the outer surface of the magnetic plate 11. When it is necessary to clean the surface of the fall arrest net 14, the fall arrest net mounting side plates 15 can be removed directly for cleaning, thereby improving the glassiness of the fall arrest net mounting side plates 15 during use.

[0041] In this invention, when the upper surface of the magnetic plate 11 and the fall arrestor net 14 on the inner side of the outer buffer side plate 2 is impacted, the magnetic plate 11 will be displaced downwards, causing the outer buffer side plate 2 to stretch the buffer springs 20 on both sides of the upper surface of the central limiting plate 17. As a result, the buffer springs 20 undergo elastic deformation, which, together with the damping effect of the buffer damper 22 at the bottom of the damping rod 21, can buffer the vibration amplitude under the combined action, thereby improving the overall impact resistance and service life of the outer buffer side plate 2 during use.

[0042] In this invention, when multiple external fall arrestor reinforcement bases 8 need to be connected, a single decorative frame body 1 can be taken out, and the horizontal locking strip 6 and vertical locking strip 7 on one side of the external fall arrestor reinforcement base 8 can be aligned with the interior of the connecting horizontal locking groove 23 and connecting vertical locking groove 25 on the other side of the external fall arrestor reinforcement base 8. Then, the resistance pads 24 on both sides of the horizontal locking strip 6 abut against the inner wall of the connecting horizontal locking groove 23, so that the resistance pads 24 will generate friction and resistance with the interior of the connecting horizontal locking groove 23, thereby generating frictional resistance between multiple external fall arrestor reinforcement bases 8, so that the external fall arrestor reinforcement bases 8 are less likely to fall off, and increasing the firmness and stability of the connection between multiple external fall arrestor reinforcement bases 8.
