[0002] Special equipment refers to equipment types that are related to personnel safety and have high risks, including boilers, pressure vessels (including gas cylinders), pressure pipelines, elevators, lifting equipment, passenger ropeways, large amusement equipment, and special motor vehicles used in factories or sites.

[0003] When performing inspection and maintenance work on special equipment installed at heights, operators often need to carry a variety of repair and inspection tools. Due to the special working environment, carrying and managing these tools is inconvenient, especially when working at heights, where tools are prone to slipping from heights, which not only increases operational risks but may also pose safety hazards to workers or personnel on the ground.

[0004] Chinese patent application CN220601198U discloses a safety protection device for special equipment inspection. By rotating and adjusting the first and second combined arc plates, both combined arc plates can be snapped and fixed onto the guardrail. Then, by rotating two third bolts, the first and second combined arc plates are installed and fixed. In this way, the inspection personnel can install the safety belt at the waist position, and use the safety belt to further protect the safety of the workers.

[0005] The safety belt in the aforementioned patented technology is secured by a first merging arc plate, a second merging arc plate, and an elastic band. In the event of a sudden fall, the elastic band will stretch during the fall, extending the free fall distance and increasing the difficulty of rescue. Therefore, a special equipment inspection safety protection device is proposed here. Utility Model Content

The rotating shaft 202 is slidably mounted on the fixed plate 205. A coil spring 206 is installed between the fixed plate 205 and the rotating shaft 202. When the rotating shaft 202 rotates, the coil spring 206 will deform, and the elastic force of the coil spring 206 can drive the rotating shaft 202 to return to its original position.

[0030] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 A safety belt 203 is provided on the rotating shaft 202, and a steel rope 204 is fixed on the safety belt 203. The steel rope 204 is connected to the rotating shaft 202 and is wound around the rotating shaft 202. A braking component for braking the rotating shaft 202 is provided on the mounting base 201.

[0031] The braking component includes a connecting plate 219, which is connected to the rotating shaft 202. An elastic telescopic rod 207 is fixed on the connecting plate 219, and a fixing block 211 is fixed on the elastic telescopic rod 207. The fixing block 211 is fixed to the connecting plate 219.

[0032] Please refer to this carefully. Figure 4 A first hook rod 208 is rotatably connected to the elastic telescopic rod 207, a connecting rod 209 is rotatably connected to the first hook rod 208, and a second hook rod 210 is rotatably connected to the connecting rod 209.

[0033] The second hook rod 210 and the first hook rod 208 are both rotatably connected to the connecting plate 219. The mounting base 201 is fixed with a positioning shaft 215. The first hook rod 208 and the second hook rod 210 are rotatably connected to the connecting plate 219 through the positioning shaft 215.

[0034] A first connecting sleeve 212 is fixed on the elastic telescopic rod 207, and a first hook rod 208 is rotatably connected to the elastic telescopic rod 207 through the first connecting sleeve 212. A second connecting sleeve 213 and a third connecting sleeve 214 are fixed on the connecting rod 209.

[0035] The second hook rod 210 and the first hook rod 208 are rotatably connected to the connecting rod 209 via the third connecting sleeve 214 and the second connecting sleeve 213, respectively. The first hook rod 208 is rotatably connected to the connecting rod 209 via the second connecting sleeve 213.

[0036] The braking component also includes a limiting ring 216, on which evenly distributed limiting blocks 217 are fixed, and a fixing rod 218 is fixed on the limiting ring 216, which is fixed to the mounting base 201.

[0037] Working principle: When in use, the safety belt 203 is first worn. When the maintenance personnel walk, the safety belt 203 will pull the rotating shaft 202 to rotate through the steel rope 204. At the same time, the steel rope 204 will extend. At this time, the coil spring 206 will deform under the rotation of the rotating shaft 202. The elastic force generated by the deformation of the coil spring 206 can drive the rotating shaft 202 to rotate. The rotation of the rotating shaft 202 will cause the steel rope 204 to be wound back onto the rotating shaft 202, thus avoiding the problem of the steel rope 204 extending too long, affecting the movement of the maintenance personnel, and making it inconvenient to retract the steel rope 204.

[0038] When maintenance personnel accidentally fall, the safety belt 203 and steel rope 204 will quickly pull the rotating shaft 202, which in turn will cause the rotating shaft 202 to quickly drive the connecting plate 219, elastic telescopic rod 207, first hook rod 208, connecting rod 209, and second hook rod 210 to rotate. The first hook rod 208 and the second hook rod 210 will rotate on the positioning shaft 215, which will cause the first hook rod 208 to squeeze the elastic telescopic rod 207 through the first connecting sleeve 212, causing the elastic telescopic rod 207 to contract. The elastic force of the elastic telescopic rod 207 will then drive the first hook rod 208 to return to its original position.

[0039] Under the action of centrifugal force, the second hook rod 210 and the first hook rod 208 will be fastened to the limit block 217, thereby preventing the connecting plate 219 and the rotating shaft 202 from rotating, thus tightening the safety belt 203 and the steel rope 204. This device can quickly tighten the safety belt 203 in the event of a sudden fall, avoiding the problem of increased falling distance caused by large-scale stretching.
