[0002] In modern industry and construction, confined space operations and emergency rescue have become an important research and application direction. Confined space usually refers to an environment with small working space, poor ventilation, and lack of natural light, such as underground pipelines, wells, storage tanks and underground parking lots. Although these places are limited in area, the transportation and rescue needs of workers are extremely urgent. Especially in the event of an accident or emergency, timely rescue of personnel is particularly important. At this time, a confined space vertical transportation and emergency rescue device is needed.

The rear end of the first rotating rod 23 passes through the fixed plate 24 and is fixedly connected to a first gear 25. A fixed rod 26 is fixedly connected to the middle and upper part of the rear side of the fixed plate 24. A hollow rod 27 is slidably connected to the outer side of the fixed rod 26. The outer side of the hollow rod 27 is fixedly connected to the second gear 210. The second gear 210 is meshed with the first gear 25, and a movable shaft 212 is provided on the right side of the cage 5. A ladder rack 214 is provided on the right side of the hole 21. A limit assembly 28 is provided on the left side of the ladder rack 214. The limit assembly 28 includes an extension plate 281. The two extension plates 281 are fixedly connected to the front and rear ends of the left side of the ladder rack 214. An opening groove 282 is provided on the adjacent sides of the two extension plates 281. The front and rear ends of the movable shaft 212 are respectively slidably connected to the corresponding opening grooves 282. The front and rear ends of the left end of the ladder rack 214 are fixedly connected to the inside of the front and rear ends of the ladder rack 214. There is a rack 283, the front and rear ends of the right side of the cage 5 are fixedly connected with a support ring 284, the front and rear ends of the movable shaft 212 are respectively rotatably connected inside the corresponding support ring 284, the front and rear sides of the outer wall of the movable shaft 212 are fixedly connected with a cylindrical gear 285, and the two cylindrical gears 285 are respectively engaged with the corresponding rack 283. An anti-falling assembly 29 is provided on the outside of the first rotating rod 23, and the anti-falling assembly 29 includes a support seat 291 and a safety rope 295. The two support seats 291 are respectively fixedly connected to the front and rear sides of the cage 5, and the front and rear sides of the ladder frame 214 are respectively fixedly connected. The sides are fixedly connected to support plates 292, and the adjacent sides of the two support plates 292 are rotatably connected to the same second rotating rod 293. The front and rear sides of the outer walls of the second rotating rod 293 and the first rotating rod 23 are fixedly connected to winding wheels 294. Multiple support seats 291 are respectively connected to the corresponding winding wheels 294 through safety ropes 295. A U-shaped ring 213 is provided on the outside of the servo motor 22.

The rear end of the hollow rod 27 is fixedly connected to the crank handle 211; Specifically, the servo motor 22 can drive the first rotating rod 23 to rotate. As the first rotating rod 23 rotates, the reel 294 on its outer side will also drive the reel 294 on the second rotating rod 293 to rotate together. This linkage mechanism enables the cage 5 to move up and down smoothly and reliably under the traction of the safety rope 295 to complete the lifting task. During the lifting process of the cage 5, the movable shaft 212 on the rear side will slide up and down smoothly inside the open groove 282, ensuring the stability of the cage 5 during the movement. At the same time, the cylindrical gear 285 on the outer side of the movable shaft 212 will move up and down on one side of the rack 283, further enhancing The stability of the cage 5 during the lifting process is ensured. When encountering an emergency power outage, the staff on the floor 1 can move the hollow rod 27 forward so that the second gear 210 is correctly engaged with the first gear 25. Then, the hollow rod 27 can be driven to rotate on the outside of the fixed rod 26 through the crank 211. This rotational action will be transmitted to the second gear 210, causing it to rotate, and then drive the first gear 25 to rotate together. As the first gear 25 rotates, the first rotating rod 23 will also rotate accordingly, thereby realizing the winding of the safety rope 295. Even in the case of a power outage, the cage 5 can still maintain normal operation, ensuring the timeliness and effectiveness of emergency rescue work.

[0022] The engaging mechanism 3 includes a bottom plate 31, which is fixedly connected to the middle of the right side of the cage 5. The top of the bottom plate 31 is fixedly connected to an electric telescopic rod 32, the output end of the electric telescopic rod 32 is fixedly connected to a T-shaped plate 33, and the front and rear ends of the right side of the T-shaped plate 33 are fixedly connected to pawls 34. The middle part of the outer side of the movable shaft 212 is fixedly connected to a plurality of ratchets 35, and two ratchets 35 are respectively engaged with corresponding pawls 34; Specifically, the electric telescopic rod 32 can be started through the control panel 7. After starting, the electric telescopic rod 32 will drive the T-shaped plate 33 to move downward until the pawl 34 on the T-shaped plate 33 is accurately engaged with the ratchet 35 on the movable shaft 212. Once the pawl 34 is successfully engaged with the ratchet 35, the movable shaft 212 can be effectively limited to stop its rotation. This process can prevent the cage 5 from continuing to fall in time, greatly reducing the risk of the cage 5 falling after long-term use.

[0023] The adjusting mechanism 4 includes a cavity 41, which is opened inside the cage 5, and a servo motor 42 is fixedly connected to the bottom front end of the cage 5. The output end of the servo motor 42 passes through the cavity 41 and is fixedly connected to a bidirectional screw rod 43. The front and rear ends of the outer sides of the bidirectional screw rod 43 are both threadedly connected to movable blocks 44. A limiting groove 45 is opened on the inner bottom of the cavity 41. The bottoms of the two movable blocks 44 are both slidably connected to the inside of the limiting groove 45. The inside of the cavity 41 is slidably connected to a first protective net 46. A protective door 48 is provided on the left side of the cage 5. The inside of the protective door 48 is slidably connected to a second protective net 410. A transmission assembly 47 is provided at the bottom of the first protective net 46. The transmission assembly 47 includes a first rotating shaft 471 and a connecting plate 474. The two first rotating shafts 471 are respectively rotatably connected to the top of the corresponding movable blocks 44. The front and rear ends of the bottom rear side of the first protective net 46 are fixedly connected A U-shaped plate 472 is connected, and the interior of the U-shaped plate 472 is rotatably connected to a second rotating shaft 473. The two second rotating shafts 473 are respectively connected to the corresponding first rotating shafts 471 through connecting plates 474. A plug-in component 49 is provided inside the second protective net 410. The plug-in component 49 includes a groove 491. The groove 491 is opened in the middle of the inner side of the second protective net 410. A two-way electric push rod 492 is fixedly connected to the inner bottom of the second protective net 410. The output end of the two-way electric push rod 492 is fixedly connected to the plug rod 493. One end of the plug rod 493 passes through the second protective net 410 and the first protective net 46 respectively. The adjusting mechanism 4 also includes an armrest 411. The two armrests 411 are rotatably connected to the left and right sides of the protective door 48 respectively. The upper and lower sides of the left end of the protective door 48 are fixedly connected with hinges 412. The protective door 48 is rotatably connected to the left side of the cage 5 through the hinge 412. Specifically, the two-way electric push rod 492 drives the insertion rod 493 at both ends to move, so that the insertion rod 493 can be smoothly inserted into the pre-set hole of the first protective net 46. When the insertion rod 493 is successfully inserted into the hole, the second protective net 410 can be spliced ​​into a whole with the first protective net 46. Then, the servo motor 42 can drive the two-way screw rod 43 to rotate, and the movable blocks 44 on both sides of the two-way screw rod 43 will move toward the middle. At the same time, the first rotating shaft 471 on the top of the movable block 44 will rotate accordingly, and the second rotating shaft 473 also starts to rotate through the synergistic action of the connecting plate 474. This series of linkage effects enables the first protective net 46 and the second protective net 410 to be lifted up evenly and stably. This design not only adapts to workers of different heights, but also greatly reduces the risk of falling they may face during construction, ensuring the safety of the operation.

[0024] The front and rear ends of the right side of the ladder frame 214 are fixedly connected to the reinforcing ribs 6, and the inner rear side of the cage 5 is fixedly connected to the control panel 7, which is electrically connected to the servo motor 22, the electric telescopic rod 32, the servo motor 42 and the bidirectional electric push rod 492 respectively; Specifically, the reinforcing ribs 6 can further increase the installation stability of the ladder frame 214, and the ladder frame 214 can be used for people to go up and down in the event of a power outage. The control panel 7 can be used to control the operation of the servo motor 22, the electric telescopic rod 32, the servo motor 42 and the bidirectional electric push rod 492. The model of the servo motor 22 is MSMF012L1U2M A6, the model of the electric telescopic rod 32 is XTL1000, the model of the servo motor 42 is RS260, and the model of the bidirectional electric push rod 492 is LA40 series.

[0025] Working principle: When the cage 5 is used, the servo motor 22 can drive the first rotating rod 23 to rotate, and the reel 294 on the outside thereof will drive the reel 294 on the second rotating rod 293 to rotate. The cage 5 will move up and down to perform the lifting work under the traction of the safety rope 295. When the cage 5 moves up and down, the movable shaft 212 on the rear side will slide up and down inside the opening groove 282. At this time, the cylindrical gear 285 on the outside of the movable shaft 212 will move up and down on the side of the rack 283, thereby further increasing the height of the cage 5. Lifting stability: When encountering an emergency power outage, the hollow rod 27 is first moved forward to engage the second gear 210 with the first gear 25. Then, the crank 211 can drive the hollow rod 27 to rotate outside the fixed rod 26. The second gear 210 will rotate accordingly, thereby driving the first gear 25 to rotate. At this time, the first rotating rod 23 will rotate accordingly to reel in the safety rope 295. The cage 5 can still be used normally during the power outage, thereby ensuring the timeliness of emergency rescue work and meeting the needs of users. And when the cage 5 suddenly falls after being used for a long time, the staff inside the cage 5 can start the electric telescopic rod 32 through the control panel 7. The electric telescopic rod 32 can drive the T-shaped plate 33 to move downward until the pawl 34 engages with the ratchet 35 on the movable shaft 212. At this time, the movable shaft 212 can be limited to stop rotating, thereby preventing the cage 5 from falling further, reducing the risk of the cage 5 falling after long-term use, and thus improving the work safety of the staff; When the staff turns the handrail 411 to open the protective door 48 and enter the cage 5, they can close the protective door 48 by turning the handrail 411 in the opposite direction, and then observe the height difference between their own height and the overall height of the cage 5. When the height difference is too large, the two-way electric push rod 492 can drive the insertion rod 493 at both ends to move so that they can be inserted into the corresponding holes respectively. At this time, the second protective net 410 and the first protective net 46 can be spliced ​​into a whole. Then, the servo motor 42 can drive the two-way screw rod 43 to rotate, and the movable blocks 44 on both sides of the two-way screw rod 43 will move toward the middle. The first rotating shaft 471 at the top of the movable block 44 will rotate accordingly, and the second rotating shaft 473 will also rotate through the connecting plate 474, so that the first protective net 46 and the second protective net 410 can be lifted up, which can meet the needs of staff of different heights and prevent them from falling during construction.
