Description

Technical Field

[0001] This invention relates to the field of safe construction technology. More specifically, this invention relates to a safe height-climbing protection device. Background Technology

[0002] During steel structure construction, the installation of components between columns includes beam-column installation and beam-bracing installation. When installing beam-bracing, safety ropes are hung on the main steel beams along each axis. Before trial use, the safety ropes should undergo a fall-prevention load-bearing test to ensure their strength meets safety requirements. Construction workers walk on the safety ropes while wearing safety belts. The safety ropes are typically hung on the columns, which are then installed on the upper flange of the steel beams using steel clamps. The installation is secured by tightening bolts. Since the tightening installation involves the safety of construction workers, it is highly necessary to improve the installation by taking further tightening measures to ensure construction safety even when the safety ropes are extended. Summary of the Invention

[0003] This invention provides a safety device for climbing at heights, which can be securely installed on the upper flange of a steel beam to ensure that the safety rope is taut and the safety belt is suspended, thereby improving construction safety.

A column-pulling safety rope is installed on the outside of the steel clamp.

[0011] The locking structure includes a locking screw and nut assembly and a tightening assembly. The tightening assembly includes an L-shaped first steel rod, a linear second steel rod, an I-shaped third steel rod, and an irregularly shaped steel frame. The irregularly shaped steel frame is sequentially provided with a first rotating shaft, a second rotating shaft, and screw holes extending from top to bottom, all parallel to the side edges of the upper flange of the steel beam. One end of the first steel rod is fixedly sleeved on the reduced-diameter portion of the third steel rod, and the other end is movably sleeved on the first rotating roller to achieve a rotatable connection with the steel pad. The apex of the first steel rod is movably sleeved on the first rotating shaft to achieve a rotatable connection with the steel pad. The irregular steel frame is rotatably connected. One end of the second steel rod is movably sleeved on the second rotating shaft to achieve a rotatable connection with the irregular steel frame, and the other end is movably sleeved on the second rotating roller to achieve a rotatable connection with the steel pad. The locking screw and nut assembly includes a first locking screw and nut that passes through each wrapping surface of the steel clamp and presses against the steel pad, and a second locking screw and nut that passes through the irregular steel frame and presses against the upper flange of the steel beam. When the second locking screw and nut presses against the upper flange of the steel beam, the third steel rod presses against the steel clamp.

[0012] Preferably, the irregular steel frame includes an integrally formed first connecting part and a second connecting part. The first connecting part includes a pair of parallel steel panels and is provided with a first rotating shaft and a second rotating shaft. The second connecting part includes a steel box beam and is provided with screw holes.

[0013] Preferably, the free end of the second connecting part is provided with a through hole, and the irregular steel frame body also includes a third connecting part. The third connecting part includes a reinforcing plate, which is a C-shaped structure. The opening of the reinforcing plate wraps around the opposite edge of the upper flange of the steel beam, and each wrapping surface forms a certain distance with the upper flange of the steel beam. A pair of parallel panels of the reinforcing plate are movably installed with the through hole through pins. The middle plate of the reinforcing plate is provided with a screw hole. The third connecting part also includes a first locking screw nut that passes through the screw hole and presses against the opposite edge of the upper flange of the steel beam.

[0014] Preferably, there are multiple through holes, arranged horizontally at fixed intervals.

[0015] Preferably, the top and bottom surfaces of the upper flange of the steel beam are provided with storage grooves along its width direction, and the storage grooves are detachably snapped with protective covers.

[0016] The present invention has at least the following beneficial effects:

[0017] First, the present invention uses a steel pad and a steel clamp to lock the steel beam, with the steel clamp locked to the steel pad and the steel pad locked to the upper flange of the steel beam, to achieve dual-point locking. This facilitates the pulling of the safety rope, ensures that the safety rope is taut and suspends the safety belt, and improves construction safety.

[0018] Second, the steel pads include an upper pad and a lower pad, respectively attached to the upper and lower surfaces of the upper flange of the steel beam. The upper and lower pads have a tightening surface for the locking screw. The upper and lower pads are provided with a first storage groove and a second storage groove for installing the first rotating roller and the second rotating roller. A pair of parallel panels of the steel clamp have screw holes through which the locking screw passes, and also have a tightening surface for the third steel member. A column is installed on the outer side of the steel clamp to pull the safety rope. The safety rope can be a 7.7mm diameter steel wire rope suspended at a height of 1.2m, with 1.2m scaffolding pipes erected every 5m to support the safety rope, or a turnbuckle tightening method can be used. The locking structure includes a locking screw and nut assembly and a tightening surface. The assembly consists of a first steel rod and a second steel rod rotatably connected relative to the irregularly shaped steel frame. One end of the first steel rod is fixedly connected to the reduced-diameter section of the third steel rod, which has a uniform outer diameter and is equipped with limiting structures at the top and bottom. Simultaneously, the other ends of the first and second steel rods are rotatably connected relative to the steel pad, thereby enabling the irregularly shaped steel frame to swing, raising or lowering the third steel rod. The first locking screw and nut of the locking screw and nut assembly locks the steel clamp plate relative to the steel pad plate, and the second locking screw and nut locks the irregularly shaped steel frame relative to the upper flange of the steel beam, while also locking the irregularly shaped steel frame relative to the steel clamp plate, forming a multi-point connection to further ensure a secure installation.

[0019] Third, the steel pad is designed as a one-piece molded C-shaped structure, so that the opening of the steel pad precisely wraps around the side edge of the upper flange of the steel beam. The two parallel panels of the steel pad pull against each other. Further increasing the pre-reserved gap between the outer side of the steel pad and the steel clamp allows for the addition of a first locking screw nut. This double-layer wrapping provides protection for locking and tightening. The irregularly shaped steel frame is configured as a first and second connecting part. The first connecting part is a panel, providing a mounting location for the rotating shaft and reducing weight. The second connecting part is a steel box girder, with upper and lower double-layer panels guiding the locking screw. A through hole is provided in the second connecting part. A third connecting part is added to the irregularly shaped steel frame. Disassembly of the second and third connecting parts is achieved by inserting a pin through the through hole. The reinforcing plate of the third connecting part matches the width of the upper flange of the steel beam, wrapping around the upper flange from the reverse direction to further achieve stable and secure installation contact. This, combined with the addition of a first locking screw nut, provides protection for locking and tightening through complete wrapping. Multiple through holes are used to facilitate matching the optimal splicing length. The storage compartment and protective cover can be installed and removed using a flexible snap-fit ​​mechanism to protect the internal structure.

The apex of the first steel rod 8 is movably sleeved on the first rotating shaft to achieve a rotatable connection with the irregularly shaped steel frame 11. The shaped steel frame 11 is rotatably connected. One end of the second steel rod 9 is movably sleeved on the second rotating shaft to achieve a rotatable connection with the shaped steel frame 11, and the other end is movably sleeved on the second rotating roller to achieve a rotatable connection with the steel pad 3. The locking screw and nut assembly includes a first locking screw and nut 6 that passes through a pair of parallel panels on the steel clamp 5 and presses against the steel pad 3, and a second locking screw and nut 7 that passes through the shaped steel frame 11 and presses against the upper flange 4 of the steel beam.

The steel clamp 5 is locked to the steel pad 3, and the steel pad 3 is locked to the upper flange 4 of the steel beam, so as to achieve dual-point locking, which facilitates the pulling of the safety rope 2, ensures that the safety rope 2 is taut and hangs the safety belt, and improves construction safety.

The reduced diameter section is a uniform outer diameter section with limiting structures at the top and bottom. At the same time, the other ends of the first steel rod 8 and the second steel rod 9 are rotatably connected to the steel pad 3, thereby driving the irregular steel frame 11 to swing, causing the third steel rod 10 to be raised or lowered. The first locking screw nut 6 of the locking screw and nut assembly locks the steel clamp 5 relative to the steel pad 3, and the second locking screw nut 7 locks the irregular steel frame 11 relative to the upper flange 4 of the steel beam, and also locks the irregular steel frame 11 relative to the steel clamp 5, forming a multi-point connection, which further ensures the tight installation.

[0037] The locking structure includes a locking screw and nut assembly and a tightening assembly. The tightening assembly includes an L-shaped first steel rod 8, a linear second steel rod 9, an I-shaped third steel rod 10, and an irregularly shaped steel frame 11. The irregularly shaped steel frame 11 is sequentially provided with a first rotating shaft, a second rotating shaft, and screw holes opened from top to bottom, parallel to the side edge of the upper flange 4 of the steel beam.
