Description

Technical Field

[0001] This utility model relates to the field of high-altitude passenger transport technology, specifically a climbing device with fall protection function suitable for various environmental conditions. Background Technology

[0002] In daily work involving traversing high-risk environments, especially those involving vertical climbing, sloping passage, or combinations of various conditions, frequent climbing poses a risk of falls from heights. To ensure the safety of climbers, effective protective measures are generally mandatory. During equipment maintenance, frequent passage through such environments daily places high demands on the physical fitness of personnel. In today's modern world, effectively ensuring worker safety while minimizing energy expenditure during climbing, conserving sufficient energy for subsequent work, and ensuring safe and efficient on-site operations are urgent issues that management must address.

[0003] Currently, to reduce the excessive physical exertion of workers during climbing, steel wire rope climbing aids are generally used to assist in vertical passage. However, steel wire rope climbing aids have the following drawbacks:

[0004] First, the travel distance is limited. The equipment is pulled and lifted by steel wire rope. The steel wire rope rotates back and forth between the upper and lower guide wheels. If the distance is too long, the steel wire rope will sway too much. In addition, the temperature difference between day and night is too large. There is a situation of thermal expansion and contraction, which can easily lead to the risk of the rope coming off, making the equipment a certain risk hazard.

[0005] Second, the application range is narrow. It can only be used in dry and comfortable environments. It cannot be used in humid environments, especially in some passage areas that may be submerged underwater depending on the operation of water and electricity. In such cases, steel wire rope climbing equipment cannot be used.

[0006] Third, the device itself does not have a fall protection function. If the wire rope breaks under extreme working conditions, it cannot be effectively stopped at the fault location, and thus cannot protect the safety of passengers.

[0007] Fourth, the application scenarios are limited. Currently, mainstream products on the market only provide climbing solutions for vertical working conditions. However, in actual working environments, there are many situations involving inclined or combined conditions. There is currently no method that can solve the continuous personnel passage problem in such environments. There is an urgent need to find a method that can simultaneously address vertical, inclined, and combined conditions while minimizing personnel movement, ensuring the safe and efficient conduct of maintenance work. Summary of the Invention

[0066] There are two motors 32. The drive shafts of the two motors 32 are equipped with active bevel gears 33. The active bevel gears 33 mesh with driven bevel gears 34 that pass through the drive mechanism. One end of the shaft where the driven bevel gears 34 are located is equipped with an output gear 37. The output gear 37 meshes with the rack 13 in the track system.

[0067] The aforementioned components are installed in an orderly manner on the upper guide frame 21. The device is powered by a dual-motor drive, with the motors having a stop brake function. The device rises and falls by controlling the forward and reverse rotation of the motor 32 through the system program.

[0068] like Figure 11-12 In the above, the manned walking device 7 includes a riding device 4, which consists of a support plate 41, a self-lubricating bearing 42, a foot pedal 43, and an operating platform 44. The support plate 41 is provided with an operating rod guide rod 41-2 for the anti-fall braking system balance linkage, an operating rod guide hole 41-1, and an operating rod mounting support frame 41-3.

[0069] like Figure 13 In this system, the fall arrest braking system 5 works in conjunction with the fall arrest guide rail 14 to ensure the safety of the device and the personnel passing through. The fall arrest braking system 5 consists of the fall arrest braking system 5 and the personnel fall arrest device 50. The fall arrest braking rod 51 in the fall arrest braking system 5 is installed inside the fall arrest braking system and the mounting shaft 21-4 of the upper guide frame 21, and is held in a locked position by the return spring 52. A sliding sleeve 53 is provided at the end of the fall arrest braking rod 51 away from the fall arrest guide rail 14. A balance bar 54 is ball-hinged on the sliding sleeve 53.

[0073] Example 3:

[0074] Combination Figure 14 As shown in Example 2, the method of using a climbing device with fall protection function suitable for various environmental conditions includes the following steps:

[0075] 1) Track System 1 Installation

[0076] A track system 1 is installed along the entire length of the personnel passage area, and fall-prevention guide rails 14 are installed on the guide rails along the entire length of the guide rails simultaneously;

[0077] 2) Installation of climbing device

[0078] Install the climbing device onto the track system 1 in the correct direction and adjust the device's balance to ensure that the device's output gear 37 effectively meshes with the track system's rack 13.

[0079] 3) Installation of personnel fall protection device 50

[0080] The personnel fall protection device 50 is installed in the direction of the fall protection guide rail 14, and then the anti-reverse plate 14-2 is installed on the fall protection guide rail 14 to prevent the personnel fall protection device 50 from sliding out of the fall protection guide rail 14. The guide rail 14-1 body is machined with an overlapping braking platform 14-1-1, a safety brake rod clearance groove 14-1-2 and a thrust plate mounting threaded hole 14-1-3.

[0081] 4) Passengers riding

[0082] Passengers should fasten their seat belts, stand with both feet on the foot pedals 43, and ensure that the seat belts are effectively connected to the personnel fall protection device 50. Passengers should also firmly grip the operating levers 56 with both hands.

[0083] 5) Passengers moving up and down

[0084] 5.1) Personnel fall protection device 50 is released from braking state.

[0085] Passengers can pull the personnel fall protection device 50 backward by using the chest suspension point of the fall protection seat belt, so that the personnel fall protection device 50 is effectively separated from the fall protection platform 14-1-1 of the guide rail 14, and personnel can climb down to pass.

[0086] 5.2) The device's fall protection system is deactivated.

[0087] Personnel raise their hands upwards to effectively separate the fall arrest brake lever 51 from the fall arrest guide rail 14, press the power button with both hands, the system performs a self-check, and after the self-check equipment is normal, the device is powered on and moves.

[0088] 6) Fall Braking Protection

[0089] In the event of an accident involving access equipment or personnel, the fall protection system will automatically activate to protect both personnel and equipment.

[0090] 6.1) Personnel fall protection device in braking state 50

[0091] When the personnel fall protection device 50 loses external force and a person falls downwards, the functional components of the personnel fall protection device are restricted to the falling position by the fall protection platform 14-1-1 of the fall protection guide rail 14, so as to achieve reliable protection for the falling person.

[0092] 6.2) Braking status of the device's fall protection system

[0093] When the device loses power, passengers will press the operating lever 56 downwards with both hands as needed, so that the device's anti-fall brake lever 51 is close to the anti-fall platform 14-1-1 of the anti-fall guide rail 14, thereby effectively preventing the device from falling. At the same time, the anti-fall device can also effectively prevent the device from falling under the weight of the anti-fall brake system and the spring reset function.

[0094] The above-described solution enables workers to safely and efficiently climb vertically and traverse slopes within the maintenance area of ​​a hydropower station dam. This device not only protects the health and safety of workers but also significantly reduces physical exertion, improving the safety and efficiency of maintenance work. Furthermore, its simple structure and convenient installation allow it to flexibly adapt to various complex working conditions, making it a promising solution for a wide range of applications.
