Description

Technical Field

[0001] This application belongs to the field of construction safety fall prevention technology, specifically a construction safety fall prevention device. Background Technology

[0002] Construction safety fall arrestors are key equipment for ensuring construction safety, primarily used to connect fall arrestor boxes. They are reliably attached to stable points at high locations via connecting components. In the event of an accidental fall, the fall arrestor box can be immediately braked and locked, effectively cushioning the impact and preventing it from falling further, thus providing safety protection for the construction area and the area below.

[0003] For example, CN216042786U discloses a safety fall arrest device for construction, relating to the field of building construction technology. It includes a roof slab, a fall arrest device, a connecting rod, and a hydraulic device. The hydraulic device is equipped with a pressure gauge and a vertically upward hydraulic rod. A connecting rod is fixed to the hydraulic rod, and multiple climbing ladders are mounted on the connecting rod. The upper end of the connecting rod is equipped with the fall arrest device, which has a safety belt fixing ring. A roof slab is located above the fall arrest device, and a rubber pad is provided on the roof slab. This utility model has a simple structure, is easy to install and use, has high safety, is suitable for various working conditions, and can be installed and used with various ladders or mobile platforms, effectively preventing personnel fall accidents.

[0004] However, during construction, the safety fall arrestor described in this application may be subject to issues due to the lack of suitable hooks. Workers might carelessly drape their safety helmets over critical components of the device, such as ropes, braking mechanisms, or connection points. This could obstruct the normal sliding of the rope and affect the accurate triggering of the braking locking mechanism when the device needs to function as a fall arrestor, thus reducing the device's fall arrest reliability and posing a significant safety hazard during construction. In the event of an accidental fall, the device might fail to brake effectively, with potentially disastrous consequences. Utility Model Content

[0005] The purpose of this application is to provide a safety fall arrest device for construction in order to solve the aforementioned safety problems.

[0006] The technical solution adopted in this application is as follows: a construction safety fall arrest device includes a fall arrest box, a connecting plate is fixedly connected to one side of the fall arrest box, a plurality of telescopic rods are provided on one side of the connecting plate, a hook fixing plate is provided at one end of the telescopic rods relative to the connecting plate, a plurality of hook bases are fixedly connected to one side of the hook fixing plate, and a hook is fixedly connected to one end of the hook bases relative to the hook fixing plate.

[0007] By adopting the above technical solution, a retractable helmet hook structure is added to a construction safety fall arrestor. During use, the hook fixing plate can be extended or retracted via the telescopic rod, facilitating the extension and retraction of the helmet hook. The hook base connects the hook fixing plate and the hook, ensuring the stability and uniformity of the helmet hook, and is an important component of the overall structure. On construction sites, workers often need to operate, inspect, or maintain the safety fall arrestor, which often requires both hands. With the addition of the retractable helmet hook structure, workers can easily temporarily hang their helmets on the hook without having to search for a suitable location, avoiding potential loss or damage from other construction equipment due to careless placement, making the construction process smoother and more efficient.

[0008] Different construction scenarios and the installation locations of fall arresters result in varying working environments for construction workers. The retractable design allows the hook's position and extension length to be flexibly adjusted according to actual conditions. For example, in confined spaces, the hook can be retracted to avoid occupying too much space and affecting operations; conversely, when the worker's position is slightly further from the main device, the hook can be extended, allowing the helmet to be conveniently hung closer to the worker, fully meeting diverse construction needs. The retractable helmet hook structure is designed with ergonomic principles in mind. Its height, angle, and retraction method facilitate easy helmet hanging for workers, eliminating the need for excessive bending, raising arms, or complex operations. This aligns with workers' daily habits, saving energy and improving efficiency during frequent helmet retrieval and placement. This encourages workers to use the hook structure, thereby ensuring the effective implementation of safety management measures on the construction site.

[0009] In a preferred embodiment, a fall arrestor door is rotatably connected to one side of the fall arrestor box, and a fall arrestor fixing frame is fixedly connected to one side of the fall arrestor box.

[0010] By adopting the above technical solution, the rotating door of the fall arrestor box serves as its entrance and exit, facilitating the placement and removal of items requiring protection by construction personnel. Simultaneously, it provides a tight seal when closed, preventing accidental falls and ensuring the fall arrestor function functions normally and the items are safely stored during construction. The fall arrestor box's fixing frame provides stable support for the entire box. Through reliable connections and installation structures, it is fixed to a stable support point at a high location, ensuring the fall arrestor box remains stable in various complex construction environments and fulfills its fall arrest mission.

[0011] In a preferred embodiment, a cylinder is provided on one side of the fall arrestor box fixing frame, and a base plate is fixedly connected to the lower surface of the cylinder.

[0012] By adopting the above technical solution, the cylinder can provide the power for linear reciprocating motion. In some operational aspects of the fall arrestor, it can control the vertical movement of the fall arrestor box, making the corresponding actions more precise and convenient in an automated manner, thereby improving the operating efficiency of the device. The base plate is an important component of the overall structure. Working in conjunction with other parts, it can transfer the impact force to the cushioning components in the event of an accidental fall, ensuring the stability of the entire fall arrestor box structure and preventing damage to the bottom.

[0013] In a preferred embodiment, the upper surface of the base plate is provided with a plurality of buffer springs, and the upper surface of the buffer springs is provided with a plurality of buffer plates.

[0014] By adopting the above technical solution, when the fall arrestor box falls unexpectedly, the buffer spring can absorb and buffer part of the impact force through its own elastic expansion and contraction, reducing the damage of the instantaneous impact force to the fall arrestor box and the protected items, ensuring the safety of the items inside the box, and extending the service life of the device. The buffer plate is installed on the buffer bullet. When the fall arrestor box falls, it works with the buffer spring and other components to first contact the impact surface. Through its own material properties and structural design, it further disperses and reduces the impact force, allowing the impact force to be absorbed more evenly by the buffer components, improving the overall buffering effect.

[0015] In a preferred embodiment, a plurality of limiting rods are fixedly connected to the upper surface of the base plate, and a plurality of support rods are fixedly connected to the upper surface of the base plate.

[0016] By adopting the above technical solution, the limiting rod is mainly used to limit the range of motion of the fall arrestor box, preventing excessive displacement or misalignment of components during normal use or under external force, ensuring that each component is always in the correct working position, and guaranteeing the reliable operation of the fall arrestor. The support rod provides additional support to the fall arrestor structure, enhancing the stability of the entire device, which ensures the effective implementation of fall arrest operations.

[0017] In a preferred embodiment, a top plate is fixedly connected to one end of the support rod relative to the base plate, and a rope winding motor is provided on one side of the base plate.

[0018] By adopting the above technical solution, the top plate is located at the very top of the fall arrest structure, protecting it from impacts from objects that may fall from above. It also serves as a crucial connection point for other components, ensuring the safety of the entire fall arrest structure. The rope winding motor drives the raising and lowering of the traction rope. Precise control of its rotation allows for adjustment of the rope's length and tension, thereby accurately controlling the raising, lowering, or hovering of the fall arrest box. This ensures the fall arrest box can be adjusted as needed during construction, guaranteeing construction safety.

[0019] In a preferred embodiment, a traction rope is provided on one side of the rope-winding motor.

[0020] By adopting the above technical solution, the traction rope, as a key component connecting the fall arrestor box to the upper suspension point, undertakes the task of transmitting tension. Under normal circumstances, it ensures that the fall arrestor box is stably suspended in the air. In the event of an accidental fall, it works with other braking and cushioning components to prevent the fall arrestor box from falling rapidly and ensure the safety of the protected items.

[0021] In a preferred embodiment, a traction rope passage is provided on one side of the traction rope.

[0022] By adopting the above technical solution, the traction rope passage provides a reasonable path for the traction rope, standardizes the direction of the traction rope, avoids entanglement or friction with other components during operation, ensures that the traction rope can smoothly perform its function of transmitting tension, and guarantees the normal operation of the fall arrest device.

[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0024] This application adds a retractable helmet hook structure to a construction safety fall arrestor. During use, the hook fixing plate can be extended or retracted via a telescopic rod, facilitating the extension and retraction of the helmet hook. The hook base connects the hook fixing plate and the hook, ensuring the stability and uniformity of the helmet hook and is an important component of the overall structure. On construction sites, workers often need to operate, inspect, or maintain the safety fall arrestor, tasks that often require both hands. With the addition of the retractable helmet hook structure, workers can easily temporarily hang their helmets on the hook without having to search for a suitable location, preventing potential loss or damage from other construction equipment, thus making the construction process smoother and more efficient.

[0025] Different construction scenarios and the installation locations of fall arresters result in varying working environments for construction workers. The retractable design allows the hook's position and extension length to be flexibly adjusted according to actual conditions. For example, in confined spaces, the hook can be retracted to avoid occupying too much space and affecting operations; conversely, when the worker's position is slightly further from the main device, the hook can be extended, allowing the helmet to be conveniently hung closer to the worker, fully meeting diverse construction needs. The retractable helmet hook structure is designed with ergonomic principles in mind.

This aligns with workers' daily habits, saving energy and improving efficiency during frequent helmet retrieval and placement. This encourages workers to use the hook structure, thereby ensuring the effective implementation of safety management measures on the construction site. Attached Figure Description
