Description

Technical Field

[0001] This utility model relates to the field of safety belts for high-altitude operations, and in particular to a buffer-type safety belt for high-altitude operations. Background Technology

[0002] High-altitude work refers to special operations carried out at a height of 2 meters or more above the reference plane where there is a possibility of falling. According to national standards, it is divided into five types: edge-prone, opening-prone, climbing, suspended, and cross-prone. Based on height, it is divided into four danger levels: Level I (2-5 meters), Level II (5-15 meters), Level III (15-30 meters), and Level IV (above 30 meters). When carrying out high-altitude work, safety belts must be used to protect the workers.

[0003] As shown in the reference case "A Safety Belt Wearing Tool for High-Altitude Workers" (publication number CN222092364U), an assembly guide rod is slidably mounted inside the connecting slider. Both ends of the assembly guide rod are fixedly connected to the buffer assembly plate. Support springs are fitted on both sides of the assembly guide rod, and buffer airbags are fitted on the outer sides of each pair of support springs. This utility model, by setting a buffer-type connection mechanism for the safety belt of high-altitude workers, can buffer the connection between the safety rope and the safety belt body, thereby improving the comfort and safety of high-altitude workers using the safety belt.

[0004] According to the above reference materials, the connecting slider in the above device will move up and down along the assembly guide rod under the action of external force. The movement of the connecting slider compresses the support spring and the buffer airbag. When the buffer airbag is compressed, the gas in the buffer airbag is slowly discharged under the action of the damping exhaust hole. By slowly discharging the gas in the buffer airbag, the buffer airbag and the support spring buffer and limit the connecting slider. However, when the device is used with the installation belt, the support spring and the buffer airbag do not provide ideal protection for the upper body of the worker, which can easily cause strain to the worker's body. It is also inconvenient to provide cushioning protection for the safety belt, thus reducing the effectiveness of the safety belt. Utility Model Content

[0005] Therefore, it is necessary to provide a cushioned safety belt for high-altitude operations to address the problem of inconvenience in providing cushioning protection for safety belts.

[0006] The device includes a carrying strap, a protective plate fixedly connected to the rear end of the carrying strap, a cushioning strip fixedly connected to the rear end of the top of the protective plate, and a protective mechanism provided on the inner wall of the protective plate. The protective mechanism includes a first cushioning airbag installed at the other end of the inner wall of the protective plate, a first silicone plate fixedly connected to the other end of the first cushioning airbag, and the other end of the first cushioning airbag intersecting with the first silicone plate. Second silicone plates are installed on both sides of the top of the carrying strap, and a second cushioning airbag is installed between the second silicone plate and the carrying strap.

[0007] In one embodiment, the protective mechanism further includes a conduit installed on the top of the inner wall of the protective plate, one side of which is in communication with the first buffer airbag.

[0008] In one embodiment, both ends of the conduit are connected to connecting tubes, and the other end of the connecting tube is connected to a second buffer airbag.

[0009] In one embodiment, one end of the conduit extends to the outside of the protective plate and is threaded with a sealing cap.

[0010] In one embodiment, the other side of the conduit is connected to two one-way valves.

[0011] In one embodiment, air pumps are installed on both sides of the inner wall of the protective plate, and the air outlet on the top side of the air pump is connected to a duct.

[0012] In one embodiment, an air intake pipe is connected to the other side of the top of the air pump, and the air intake pipe extends through the outer wall of the protective plate.

[0013] In one embodiment, two latches are installed at one end of the buffer strip, and a flexible block is fixedly connected to the top of the inner wall of the latches. A pressure sensor is installed on the inner wall of the flexible block. Beneficial effects

[0014] 1. The above-mentioned high-altitude work cushioned safety belt has a protective plate at the rear end of the back strap to support the worker's spine. The first cushioning airbag and the first silicone plate are installed on the protective plate to absorb and cushion the impact force on the worker's back. The second silicone plates and the second cushioning airbag on both sides of the top of the back strap can protect the worker's shoulders. The air pump delivers air through a one-way valve into the duct. The duct can deliver air to the first cushioning airbag for inflation. The duct and two connecting pipes can deliver air to the second cushioning airbag for inflation, which can buffer the pressure and improve the safety of the worker. The one-way valve can prevent air leakage in the first and second cushioning airbags. When it is safe, one end of the duct can be opened by rotating the sealing cap to release the air in the first and second cushioning airbags, which can improve the cushioning and protection effect of the safety belt and improve the safety of the safety belt. 2. The lock hole is hung on the installation point. When a worker falls, the pressure sensor inside the lock hole is subjected to pressure greater than the preset threshold, which can drive the air pump to run. The air is delivered from outside the protective plate to the duct through the air intake pipe to protect the worker. The pressure sensor is set in the flexible block on the buckle, which can protect the pressure sensor and improve the use of the pressure sensor. It can protect the worker and improve the cushioning effect of the safety belt. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The following is combined Figure 1 - Figure 5 This utility model describes a buffered safety belt for high-altitude operations.

[0020] In one embodiment, a buffered safety belt for high-altitude operations includes a back strap 100, a protective plate 200 fixedly connected to the rear end of the back strap 100, a buffer strip 300 fixedly connected to the rear end of the top of the protective plate 200, and a protective mechanism 400 provided on the inner wall of the protective plate 200. The protective mechanism 400 includes a first buffer airbag 410 installed at the other end of the inner wall of the protective plate 200, a first silicone plate 420 fixedly connected to the other end of the first buffer airbag 410, and the other end of the first buffer airbag 410 and the first silicone plate 420 intersecting each other. Second silicone plates 430 are installed on both sides of the top of the back strap 100, and a second buffer airbag 440 is installed between the second silicone plate 430 and the back strap 100.

[0021] like Figure 2 , Figure 3 and Figure 4 As shown, the protective mechanism 400 also includes a conduit 450 installed on the top of the inner wall of the protective plate 200. One side of the conduit 450 is connected to the first buffer airbag 410. Both ends of the conduit 450 are connected to connecting pipes 451. The other end of the connecting pipe 451 is connected to the second buffer airbag 440. One end of the conduit 450 extends to the outside of the protective plate 200 and is threaded with a sealing cap 452. The other side of the conduit 450 is connected to two one-way valves 453.

[0022] In this embodiment, when the harness 100 is worn by the worker, it can protect the worker's back and shoulders. When the air pump 460 delivers air to the first buffer airbag 410 and the two connecting pipes 451 through the conduit 450, the first buffer airbag 410 inflates. The air then enters the two second buffer airbags 440 through the two connecting pipes 451 and inflates. The first buffer airbag 410 and the second buffer airbag 440 cooperate with the first silicone plate 420 and the second silicone plate 430 respectively and come into contact with the worker's body. This can absorb and buffer the pressure on the worker's body and disperse the pressure. In conjunction with the buffer belt 300, it can absorb and buffer the impact force on the seat belt, improve the safety of the seat belt, and effectively buffer the impact force.

[0023] like Figure 5 As shown, air pumps 460 are installed on both sides of the inner wall of the protective plate 200. The air outlet on one side of the top of the air pump 460 is connected to the conduit 450. The other side of the top of the air pump 460 is connected to the air inlet pipe 461. The air inlet pipe 461 extends to the outer wall of the protective plate 200. Two latches 462 are installed at one end of the buffer strip 300. A flexible block 463 is fixedly connected to the top of the inner wall of the latch 462. A pressure sensor 464 is installed on the inner wall of the flexible block 463.

[0024] In this embodiment, when the pressure sensor 464 inside the latch 462 is subjected to pressure exceeding the preheating threshold, it can drive two suction pumps 460 to operate and deliver external air to the conduit 450 through the air intake pipe 461. The conduit 450 splits the air and delivers the air to the first buffer airbag 410 and the two connecting pipes 451 respectively, causing the first buffer airbag 410 and the second buffer airbag 440 to inflate, protecting the worker's body and reducing the impact force on the worker's body, thus providing a cushioning effect.

[0025] Working Principle: When a worker falls and the impact force on the pressure sensor 464 at the top of the buckle 462 exceeds a preset threshold, two suction pumps 460 are activated. External air is delivered to the conduit 450 through the intake pipe 461. The air passes through a one-way valve 453 to prevent backflow. The conduit 450 then delivers air to the first buffer airbag 410 and two connecting pipes 451. The two connecting pipes 451 deliver air to the second buffer airbag 440, causing both airbags to inflate. The first and second buffer airbags 410, in conjunction with the first and second silicone plates 420 and 430 respectively, absorb and cushion the impact force on the worker's upper body, protecting them. The cushioning belt 300, made of internal stretchable material, gradually unfolds during the fall, prolonging the impact time, converting kinetic energy into heat energy, reducing the instantaneous impact injury, and further improving the cushioning effect of the seatbelt. It should be noted that the suction pump 460 and pressure sensor 464 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the suction pump 460 and pressure sensor 464 can be powered by the built-in power supply, which will not be elaborated here.

[0026] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
