[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1: Figure 1-Figure 5As shown, the utility model provides an outdoor straight ladder anti-fall safety belt device, including a safety belt body 1, two mounting boxes 3 are fixedly installed on the outer wall of the safety belt body 1, and the inner walls of the two mounting boxes 3 are movably embedded with a fixing plate 4, and one side of the outer wall of the two fixing plates 4 is fixedly connected with a rope 5, and two buffer springs 6 are arranged inside the two mounting boxes 3, and one side of the outer wall of the buffer spring 6 is fixedly connected to one side of the outer wall of the fixing plate 4, and the inner walls of the four buffer springs 6 are each provided with a first damper 7, and a mounting plate 8 is fixedly connected between the outer walls of the two ropes 5, and the outer wall of the mounting plate 8 is movably sleeved with a fixing box 9, and the inner wall of the fixing box 9 is provided with two compression springs 11, and one side of the outer wall of the compression spring 11 is fixedly connected to one side of the outer wall of the mounting plate 8, and the inner walls of the two compression springs 11 are provided with a second damper 12, the outer wall of the safety belt body 1 is provided with a plurality of fixing buckles 2, and the outer wall of the fixing box 9 is movably sleeved with a fixing ring 10.

[0026] The effect achieved by the entire embodiment 1 is that when a worker needs to climb an outdoor vertical ladder to reach the top of a thermal power plant, the worker first opens the fixing buckle 2 installed on the safety belt and puts it on, and then fixes the safety belt again through the fixing buckle 2. During the climbing process, the fixing ring 10 is repeatedly adjusted to be sleeved on the outer wall of the vertical ladder, thereby protecting the worker. When the worker falls due to operational errors, at this time, under the action of gravity, the fixing plate 4 is driven upward inside the installation box 3 by the rope 5, and the buffer spring 6 is compressed. When the buffer spring 6 is compressed to a certain extent, the buffer spring 6 generates a large rebound force. At this time, under the action of the first damper 7, the rebound force generated by the buffer spring 6 can be partially absorbed, thereby partially absorbing the gravity during the fall and playing a buffering role. At the same time, under the action of the rope 5, the mounting plate 8 is driven downward and the compression spring 11 is compressed. Under the action of the second damper 12, the gravity of the worker when falling can be absorbed again, thereby preventing the worker from being instantly tightened by the safety belt when falling, thereby protecting the worker.

[0027] Example 2: Figure 2-Figure 5 As shown, the safety belt body 1 is composed of a first wear-resistant layer 13, a corrosion-resistant layer 14, a support layer 15, a comfort layer 16, a soft layer 17 and a second wear-resistant layer 18;

[0028] A corrosion-resistant layer 14 is provided on one side of the outer wall of the first wear-resistant layer 13, a support layer 15 is provided on one side of the outer wall of the corrosion-resistant layer 14, a comfort layer 16 is provided on one side of the outer wall of the support layer 15, a soft layer 17 is provided on one side of the outer wall of the comfort layer 16, and a second wear-resistant layer 18 is provided on one side of the outer wall of the soft layer 17. The first wear-resistant layer 13 is woven from polyester fiber, and the thickness of the first wear-resistant layer 13 is between 2-5mm, the corrosion-resistant layer 14 is made of polyvinyl chloride, and the thickness of the corrosion-resistant layer 14 is between 3-5mm, the support layer 15 is woven from polyester fiber, and the thickness of the support layer 15 is between 5-8mm, the comfort layer 16 is made of foamed polyester, and the thickness of the comfort layer 16 is between 3-6mm, the soft layer 17 is made of polyurethane, and the thickness of the soft layer 17 is between 1-4mm, and the second wear-resistant layer 18 is made of nylon fiber, and the thickness of the second wear-resistant layer 18 is between 4-8mm.

[0029] The effect achieved by the entire embodiment 2 is that when the anti-fall safety belt is in use, the first wear-resistant layer 13 and the second wear-resistant layer 18 can provide additional protection, enhance the durability of the safety belt, extend its service life, and be able to resist daily wear and tear. The corrosion-resistant layer 14 can ensure that the safety belt maintains its complete performance in an emergency situation and reduce the safety hazards caused by material degradation. The support layer 15 is an important component of the safety belt, responsible for bearing and distributing weight and impact force. In the event of a fall, it ensures that the safety belt can effectively maintain its shape and provide sufficient strength to prevent breakage due to excessive load. The comfort layer 16 uses soft material, which can effectively reduce the pressure of the safety belt on the wearer's body and enhance comfort. The soft layer 17 can absorb part of the impact force and provide necessary cushioning in the event of a fall or accident, reduce direct impact on the body, and reduce potential injury risks. The above method can extend the service life of the anti-fall safety belt and improve the comfort of use.

[0030] Working principle: When the staff needs to climb the outdoor straight ladder to reach the top of the thermal power plant, the staff first opens the fixed buckle 2 installed on the safety belt and puts it on, and then fixes the safety belt again through the fixed buckle 2. During the climbing process, the staff repeatedly adjusts the position of the fixed ring 10 set on the outer wall of the straight ladder, thereby protecting the staff. When the staff makes an operational error and falls, at this time, under the action of gravity, the rope 5 drives the fixed plate 4 to move upward inside the installation box 3 and compresses the buffer spring 6. When the buffer spring 6 is compressed to a certain extent, the buffer spring 6 will generate a large rebound force. At this time, the rebound force generated by the buffer spring 6 can be reduced by the action of the first damper 7. At the same time, under the action of the rope 5, the mounting plate 8 is driven to move downward, and the compression spring 11 is compressed. Under the action of the second damper 12, the gravity of the staff when falling can be absorbed and buffered again, avoiding the staff from being instantly tightened by the safety belt when falling. In addition, under the action of the first wear-resistant layer 13, the second wear-resistant layer 18, the corrosion-resistant layer 14 and the support layer 15, the strength of the anti-fall safety belt can be improved, damage during use can be avoided, and its service life can be extended. Under the action of the comfort layer 16 and the soft layer 17, the comfort of the anti-fall safety belt can be greatly improved, and the staff can be further protected.
