Description

Technical Field

[0001] This utility model relates to the field of safety belt technology, specifically a fall protection safety belt for high-altitude operations during the installation and maintenance of wind power generation equipment. Background Technology

[0002] Fall arrestor harnesses are indispensable safety equipment in the installation and maintenance of wind power generation equipment. These harnesses are made of high-strength webbing and metal fittings, capable of withstanding the enormous impact force generated during a fall, effectively protecting the user's safety.

[0003] The Chinese patent CN221732181U power high-altitude operation fall protection full-body safety belt is designed by securing the belt around the waist with a pair of male and female buckles, then placing the buckle on the shoulder and securing the other set of female and male buckles. When the worker wears the belt, the elastic band increases the elasticity of the straps under fall, while the elastic band also increases the belt's toughness, reducing potential hazards. Protective pads on the sides of the belt enhance worker comfort, and storage pockets on the belt surface provide temporary storage for electrical tools for easy access. Pull rings on the anchor points allow for easy attachment of climbing equipment to the belt.

[0004] In the aforementioned patent, the buckle and protective sleeve are directly connected through the safety belt body, and the protective sleeve is directly attached to the worker's shoulder. This means that when the worker is using the belt, if the protective sleeve and buckle are not specially customized, they cannot be securely fixed to the worker's shoulder, which could lead to a fall. The buckle can easily detach from the worker's body, causing an accident. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a high-altitude operation fall protection safety belt for the installation and maintenance of wind power generation equipment, including a shoulder strap, a protective component is fixedly sleeved inside the shoulder strap, a female buckle is fixedly connected to the bottom of the protective component, a female buckle is snapped into the inside of the female buckle, and a waist belt is fixedly connected to the bottom of the female buckle.

[0006] The protective component includes a buckle, a connecting strap fixedly connected to the left end of the buckle, a fixing strap fixedly connected to the front of the buckle, a limit sleeve fixedly connected to the front of the buckle, a hook and loop fastener fixedly connected to the front of the fixing strap, and a hook and loop fastener rough side fixedly connected to the front of the fixing strap.

[0007] The above technical solution, by incorporating a protective assembly including buckles, connecting straps, fixing straps, limiting sleeves, and hook and loop fasteners, ensures that the safety belt can achieve a secure fit between the shoulder strap and the user's shoulder through adjustment of the fixing straps and the use of hook and loop fasteners, preventing the shoulder strap from slipping. Furthermore, the connection method between the protective assembly and components such as the shoulder strap and waist belt guarantees the overall structural stability and reliability of the safety belt during use, thus improving the safety of personnel installing and maintaining wind power equipment at heights.

[0008] As a further improvement to the above solution, the number of buckles is set to two, and the two buckles are evenly distributed on the left and right ends symmetrically with respect to the top center of the connecting strap. The number of shoulder straps is set to two, and the two shoulder straps are respectively sleeved on the surface of the two buckles.

[0009] Through the above technical solution, the two symmetrical buckles and the two corresponding shoulder straps enable the seat belt to distribute the force evenly during use, avoiding local overstretching or loosening due to uneven force distribution, thus improving the reliability of the seat belt.

[0010] As a further improvement to the above solution, the limiting sleeve is located on the buckle surface near the hook and loop side, and the hook and loop side penetrates the limiting sleeve.

[0011] With the above technical solution, the limiting sleeve is located on the buckle surface near the hook and loop side, and the hook and loop side penetrates through the limiting sleeve. The limiting sleeve plays a limiting role on the fixing strap, allowing the fixing strap to pass through stably when tightened, which facilitates accurate bonding between the hook and loop side and the hook and loop side, further improving the fit and fixing effect of the seat belt.

[0012] As a further improvement to the above solution, a fixing seat is fixedly connected to the outer surface of the waist belt, and a hanging ring is sleeved inside the fixing seat.

[0013] Through the above technical solution, the outer surface of the waist belt is fixedly connected to the fixing seat, and the fixing seat is fitted with a hanging ring. This setting provides a stable connection point for the safety rope, and the hanging ring facilitates the quick connection and fixation of the safety rope.

[0014] As a further improvement to the above solution, two fixing seats are provided, and the two fixing seats are evenly distributed on the surface symmetrically with respect to the top center of the waistband.

[0015] With the above technical solution, two fixing seats are symmetrically distributed on the surface of the waist belt. The symmetrical distribution of the fixing seats allows the safety rope to be subjected to more even force during connection, avoiding the impact on the worker's body balance due to force imbalance.

[0016] As a further improvement to the above solution, a female buckle 2 is fixedly connected to the bottom of the waist belt, a male buckle 2 is snapped into the inside of the female buckle 2, and a pocket is fixedly connected to the bottom of the male buckle 2.

[0017] Through the above technical solution, the bottom of the waist belt is connected to the female buckle 2, the female buckle 2 is internally engaged with the male buckle 2, and the bottom of the male buckle 2 is connected to the pocket strap. This connection method allows the pocket strap and the waist belt to be firmly connected, ensuring that the lower part of the seat belt can be effectively fixed.

[0018] As a further improvement to the above solution, the waistband and the pocket are concentric.

[0019] By using the above technical solution, the waist belt and the pocket are concentric, ensuring the symmetry of the overall structure of the safety belt, so that the safety belt can be evenly distributed on the worker, reducing the risk of excessive local stress.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This utility model incorporates a protective component. During use, the fixing strap is first passed through the inside of the limiting sleeve, tightening the two shoulder straps to fit snugly against the user's shoulder. Then, the fixing strap is pulled to allow the hook and loop side of the Velcro to adhere to the surface of the Velcro loop side, effectively preventing the shoulder straps from slipping off the shoulder, avoiding accidents, and improving work safety.

[0022] This utility model, by setting up a hanging ring, makes it easy to fix the external safety rope inside the hanging ring, so that the safety belt can better protect the workers and ensure the safety of wind power equipment installation and maintenance personnel when working at height.
