Description

Technical Field

[0001] This utility model relates to the field of protective belt equipment for construction, specifically a protective belt for construction workers. Background Technology

[0002] With the continuous development of construction technology, construction scenarios are becoming increasingly diverse and complex. Safety harnesses play a vital role in the safety of workers, especially in the construction of high-rise buildings where workers need to operate at greater heights. This places higher demands on the safety performance and comfort of safety harnesses. Working at heights often involves numerous safety risks, with falls being one of the most serious threats. Therefore, the importance of safety harnesses as key equipment for ensuring the safety of workers working at heights is self-evident. Traditional safety harnesses generally only provide a single safety feature, which means that if this single safety feature malfunctions in the event of an emergency, it will pose a serious threat to the lives of construction workers.

[0003] Chinese patent discloses a protective belt for construction workers (authorization announcement number CN 209092565).

[0004] The U) includes a protective belt body, the protective belt body including a first fixing plate, a connecting block welded to the top of the first fixing plate, a safety rope provided on the connecting block, a hook one provided at one end of the safety rope, a safety belt provided on the connecting block, a hook two provided at one end of the safety belt, a connecting ring provided on the safety belt, shoulder straps provided on both sides of the top of the connecting block, a sponge belt provided on the shoulder strap, a connecting buckle one and a chest strap provided at one end of the shoulder strap, the chest strap being installed on the shoulder strap through the connecting buckle one, a storage bag provided on the chest strap, warning lights provided on both sides of the storage bag, a connecting device provided at the bottom of the chest strap, and a waist belt provided at the bottom of the fixing plate, the waist belt being installed on the chest strap through the connecting device.

[0005] While this patent can protect construction workers and the sponge belt can alleviate the pressure caused by wearing it for extended periods, it lacks safety features for high-altitude operations. In such situations, the patent only suspends the worker using two safety ropes, lacking additional safety measures in case of rope malfunctions. If the safety ropes fail, it can easily threaten the worker's life. Therefore, this utility model provides a protective belt for construction workers to address the aforementioned problems. Utility Model Content

[0006] The purpose of this utility model is to provide a protective belt for construction workers in building construction, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A protective belt for construction workers includes an upper body cover with a lower body cover at the bottom. To improve the wearing experience for construction workers, a cooling fan is fixedly installed at the rear end of the upper body cover to cool the workers. Ventilation openings for airflow are provided on the outer wall of the upper body cover, with the cooling fan's outlet located at one of the ventilation openings. A lighting lamp is fixedly installed on the outer wall of the upper body cover at the end furthest from the cooling fan. To enhance the safety of construction workers working at heights, two adjusting ropes and two safety ropes are also installed on the outer wall of the upper body cover to ensure worker safety.

[0009] As a further embodiment of this utility model, two fixing blocks are fixedly installed on the outer wall of the upper body cover, and the two safety ropes are respectively located inside the fixing blocks.

[0010] As a further embodiment of this utility model, the upper body cover is fixedly connected to two sides with storage bags that allow workers to hang commonly used tools, thereby improving work efficiency. Straps for adjusting the fit are fixedly installed on the outer walls of the upper and lower body covers that are close to each other.

[0011] As a further improvement of this utility model, a stabilizing clip to reduce swaying is installed at one end of the lower body cover.

[0012] As a further embodiment of this utility model, the fixing block includes a fixing piece fixedly connected to the outer wall of the upper body cover, a fixing shell fixedly installed on the outer wall of the fixing piece, a centrifugal disc installed inside the fixing shell, a safety rope wrapped around the outer wall of the centrifugal disc, and one end of the safety rope fixedly connected to the outer wall of the centrifugal disc.

[0013] As a further embodiment of this utility model, the centrifugal disc includes a brake disc, which is fixedly connected to the outer wall of the fixed plate near the fixed housing. A turntable is rotatably connected inside the fixed housing. Six abutments are arranged around the brake disc. Two levers and a protrusion are arranged on the outer wall of the turntable near the brake disc. One of the levers is connected to the protrusion through a return spring, and the two levers are rotatably connected together.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In order to further ensure the safety of construction workers, this utility model adopts a double safety structure. In addition to two adjusting ropes for adjusting the worker's working height, two safety ropes are also installed on the outer wall of the upper body cover to ensure the worker's safety. When a construction worker falls rapidly in danger while working, the fixed shell cannot hold the safety rope, so the safety rope inside the fixed shell extends outward quickly, causing the turntable to rotate rapidly. The two levers will unfold to both sides under the action of centrifugal force. When the levers just touch the stop block, the turntable cannot rotate, thus limiting the length of the safety rope and ensuring the safety of the construction worker.

[0016] 2. When this utility model is used, in order to alleviate the fatigue and heat of construction workers working in the hot season, the cooling fan blows air through the ventilation opening, increasing the air circulation speed on the wearer's back, accelerating the expulsion of hot air, reducing the wearer's feeling of heat, thereby relieving the wearer's fatigue and increasing their work efficiency.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-7In this embodiment of the utility model, a protective belt for construction workers includes an upper body cover 1 and a lower body cover 2. To improve the wearing experience for construction workers, the main structure of the upper body cover 1 and the lower body cover 2 is made of multi-layer composite high-strength materials, including an outer layer of wear-resistant and weather-resistant nylon fiber, a middle layer of high-strength polyester fiber tensile strength, and an inner layer of soft and comfortable cotton skin-friendly material. This structure ensures both the overall strength and durability of the protective belt and the comfort of the worker when wearing it. A cooling fan 10 is fixedly installed at the rear end of the upper body cover 1 to cool down the construction worker. The cooling fan 10 can accelerate the expulsion of hot air by increasing the airflow speed on the wearer's back, thereby alleviating the heat felt by construction workers, especially in summer. To ensure that the airflow from the cooling fan 10 can be fully directed towards the wearer, the upper body cover... The outer wall of the upper body cover 1 has a ventilation opening 12 for air circulation. The air outlet of the cooling fan 10 is located at the ventilation opening 12. A lighting lamp 6 is fixedly installed on the outer wall of the upper body cover 1 away from the cooling fan 10. It can provide good lighting for construction workers when working at night and can also eliminate the shadows caused by direct illumination from the spotlight, thereby improving the efficiency of construction workers at night. In order to improve the safety of construction workers when working at height, two adjusting ropes 13 are installed on the outer wall of the upper body cover 1. Specifically, in order to further ensure the safety of construction workers, the device adopts a double safety structure. In addition to the two adjusting ropes 13 used to adjust the height of the workers, two safety ropes 9 are also installed on the outer wall of the upper body cover 1 to ensure the safety of the workers. More specifically, two fixing blocks 4 are fixedly installed on the outer wall of the upper body cover 1, and the two safety ropes 9 are located inside the fixing blocks 4 respectively.

[0027] The upper body cover 1 has storage bags 3 fixedly connected to both sides, which can facilitate workers to hang commonly used tools and thus improve work efficiency. At the same time, in order to prevent items from falling and make it easy to retrieve tools, the storage bags 3 are sealed with Velcro closures that are easy to remove.

[0028] To increase the adaptability of the device to construction workers of different body types, straps 5 are fixedly installed on the outer walls of the upper body cover 1 and the lower body cover 2 at their closest points to each other. These straps are made of elastic braided rope, which can fit the wearer's waist while reducing the pressure on the waist, thereby increasing the wearer's comfort. Buckles 8 are installed at both ends of the straps 5 for connecting them.

[0029] Construction workers inevitably experience instability in their safety ropes 9 and adjusting devices 13 due to wind or their own swaying when working at heights. This significantly increases the safety risks for construction workers. To reduce the swaying of construction workers in the air, a stabilizing clip 7 is installed at one end of the lower body sleeve 2. Specifically, one end of the lower body sleeve 2 has an opening, and a stabilizing rope 11 is wound around the opening. The end of the stabilizing rope 11 away from the opening is fixedly connected to the outer wall of the stabilizing clip 7. By pulling out a suitable length of the stabilizing rope 11, the stabilizing clip 7 is clamped in the work area. The stabilizing rope 11 reduces the swaying of the safety rope 9 at heights, thereby increasing the safety of construction workers and improving their work efficiency.

[0030] Please see Figures 4-6 The fixing block 4 includes a fixing piece 401 fixedly connected to the outer wall of the upper body sleeve 1. A fixing shell 402 is fixedly installed on the outer wall of the fixing piece 401. A centrifugal disc 403 is installed inside the fixing shell 402. A safety rope 9 is wound around the outer wall of the centrifugal disc 403. One end of the safety rope 9 is fixedly connected to the outer wall of the centrifugal disc 403. An opening is provided at the upper end of the fixing shell 402, and the safety rope 9 is clamped at the opening of the fixing shell 402. The safety rope 9 is made of high-strength aramid fiber material, which has the characteristics of high temperature resistance and cut resistance. When construction workers are working suspended at heights, the safety rope 9 can play a protective role, ensuring that the worker can stop in time in case of a fall, thereby ensuring the worker's safety.

[0031] The centrifugal disc 403 includes a brake disc 4031, which is fixedly connected to the outer wall of the fixing plate 401 near the fixing housing 402. A turntable 4033 is rotatably connected inside the fixing housing 402. Specifically, a rotating shaft 4034 is provided on the outer wall of the turntable 4033, and the rotating shaft 4034 is rotatably connected inside the fixing housing 402. Six abutments 4032 are provided around the brake disc 4031. Two levers 4036 are provided on the outer wall of the turntable 4033 near the brake disc 4031. Specifically, a protrusion 4035 is provided on the outer wall of the turntable 4033, and one of the levers 4036 is connected to the protrusion 4035 via a return spring. The two levers 4036 are rotatably connected together. Specifically, two connecting shafts 4037 are provided on the outer wall of the turntable 4033. The two levers 4036 are rotatably connected together through the two connecting shafts 4037. When a construction worker falls rapidly in danger during work, the fixed outer shell 402 cannot hold the safety rope 9, causing the safety rope 9 inside the fixed outer shell 402 to extend outward rapidly, driving the turntable 4033 to rotate quickly. The two levers 4036 will unfold to both sides under the action of centrifugal force. When the levers 4036 just touch the stop block 4032, the turntable 4033 cannot rotate, thus limiting the length of the safety rope 9 and ensuring the safety of the construction worker.

[0032] Please see Figure 7 The cooling fan 10 includes an outer fixing frame 1001. A linkage shaft 1005 is rotatably connected to the side of the outer fixing frame 1001 near the upper body sleeve 1. Multiple fan blades are fixedly installed on the outer wall of the linkage shaft 1005. An inner fixing frame 1004 is fixedly installed inside the upper body sleeve 1. The outer fixing frame 1001 and the inner fixing frame 1004 are fixedly connected. A support frame 1002 is fixedly installed on the inner wall of the outer fixing frame 1001. A rotating mechanism 1003 that provides rotational force is rotatably connected to the outer wall of the support frame 1002 near the linkage shaft 1005. The output end of the rotating mechanism 1003 is fixedly connected to the outer wall of the linkage shaft 1005 near the outer fixing frame 1001. The airflow from the cooling fan 10 blows air through the air vent 12. The rapidly flowing air can remove heat from the wearer's back, reduce the wearer's feeling of heat, thereby reducing fatigue and increasing work efficiency.

[0033] The working principle of this utility model is as follows:

[0034] To further ensure the safety of construction workers, this device employs a double-safety structure. In addition to two adjusting ropes 9 for adjusting the worker's working height, two safety ropes 9 are also installed on the outer wall of the upper body cover 1 to ensure the worker's safety. When a construction worker falls rapidly during work, the fixed outer shell 402 cannot hold the safety ropes 9, causing the safety ropes inside the fixed outer shell 402 to extend outward quickly, driving the turntable 4033 to rotate rapidly. The two levers 4036 will unfold to both sides under the action of centrifugal force. When the levers 4036 just touch the stop block 4032, the turntable 4033 cannot rotate, thus limiting the length of the safety ropes 9 and ensuring the safety of the construction worker.

[0035] To alleviate the fatigue and heat experienced by construction workers during the hot season, a cooling fan 10 blows air through the ventilation opening 12, thereby increasing the airflow speed on the wearer's back, accelerating the expulsion of hot air, reducing the wearer's feeling of heat, relieving fatigue, and increasing their work efficiency.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
