Description

Technical Field

[0001] This invention relates to the field of high-altitude passenger transport technology, specifically a three-in-one climbing ladder track and its usage method that can support climbing devices in various environmental conditions. Background Technology

[0002] In our daily work, we often encounter situations requiring passage through high-risk environments, especially those involving vertical climbing, sloping passage, or combinations of different conditions. Frequent climbing and traversing in these environments pose a risk of falls from heights. To ensure the safety of climbers, effective protective measures are generally mandatory. For example, 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 and minimizing energy expenditure during climbing, thus conserving energy for subsequent work and ensuring safe and efficient on-site operations, typically involves using lifting devices to transport personnel. However, how to quickly evacuate personnel if equipment malfunctions is a pressing issue for management.

[0003] Currently, to ensure safe passage through passageways, dedicated ladders are typically installed for personnel to climb, allowing for emergency evacuation in case of malfunction. However, this method has the following problems:

[0004] First, when the climbing equipment malfunctions during operation, passengers cannot evacuate in time, while other personnel can evacuate in an orderly manner via a dedicated ladder, which fails to solve the fundamental problem.

[0005] Second, the layout of the climbing device system and the dedicated climbing ladder system requires a large space, but the actual site conditions often do not have enough space to install two systems, which makes the dedicated climbing ladder solution unable to be effectively implemented, thus failing to guarantee that personnel can quickly evacuate the site in the event of a failure of the climbing equipment.

[0006] Third, the price and cost are high. The special ladders set up to meet the needs of personnel evacuation are very expensive to manufacture and install, and the effective utilization rate of the separately installed special ladders is low, so their cost performance is very low. Summary of the Invention

[0007] The technical problem this invention aims to solve is to provide a three-in-one climbing ladder track and its usage method that can support climbing devices in various environmental conditions. This enables personnel to quickly evacuate the site when the climbing device malfunctions and fails to operate in complex and hazardous environments, thus protecting the lives and health of workers. The system has a simple structure, is lightweight, and is convenient and quick to use. The guide rail can be erected according to the actual site conditions, meeting the requirements for safe use in different environmental conditions.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a three-in-one climbing ladder track that can support climbing devices in various environmental working conditions, the three-in-one climbing ladder track being composed of a vertical track, a corner track, and a ramp track;

[0009] The main body of the vertical track is a vertical track base support frame. Multiple first mounting plates are provided on the back of the vertical track base support frame. The first mounting plates are fixed with fasteners. A first limiting track is provided on the vertical track base support frame, and a first ladder crossbar is provided between the first limiting tracks on both sides.

[0010] The corner track is used to connect tracks in different working conditions. The main body of the corner track is a corner track base support frame. Multiple second mounting plates are provided on the back of the corner track base support frame. The second mounting plates are fixed with fasteners. A second limiting track is provided on the corner track base support frame. A second ladder crossbar is provided between the second limiting tracks on both sides.

[0011] The main body of the ramp track is a ramp track foundation support frame. Multiple third mounting plates are provided on the back of the ramp track foundation support frame. The third mounting plates are fixed with fasteners. A third limiting track is provided on the ramp track foundation support frame. The third limiting tracks on both sides are connected by crossbars. A third ladder crossbar for emergency evacuation is provided directly below it.

[0012] In the preferred embodiment, the first limiting track, the second limiting track, and the third limiting track are connected to form a complete track system.

[0013] In a preferred embodiment, the first ladder crossbar, the second ladder crossbar, and the third ladder crossbar are connected to form a complete ladder system.

[0014] In a preferred embodiment, the inner sides of the first limiting rail, the second limiting rail, and the third limiting rail are provided with racks. The racks are used to cooperate with the climbing device provided in the rail system. The first limiting rail, the second limiting rail, and the third limiting rail are connected to form a complete rack.

[0015] In a preferred embodiment, the first ladder crossbar, the second ladder crossbar, and the crossbar are provided with fall protection guide rails to form a complete fall protection system. The fall protection guide rails are provided with brake platforms at intervals, and a clearance groove is also provided on one side of the fall protection guide rails.

[0016] The fall arrestor rail is used in conjunction with the fall arrestor of the climbing device body and the fall arrestor of personnel to achieve the purpose of preventing the climbing device and passengers from falling during operation.

[0017] In a preferred embodiment, the fall arrestor uses a rotating brake lever on its main body in conjunction with a brake platform to achieve braking and locking of the climbing device on the track.

[0018] In a preferred embodiment, the fall arrestor rail is further equipped with a backstop plate, which is used to limit the fall arrestor device from falling onto the fall arrestor rail, thereby preventing the fall arrestor device from falling off the fall arrestor rail.

[0019] In a preferred embodiment, the third mounting plate is an "L"-shaped plate, which is fixed in conjunction with mounting fasteners. One end of the "L"-shaped third mounting plate is provided with a third limiting rail, and the other end is provided with a third ladder crossbar. A passageway is formed between the third limiting rail and the third ladder crossbar.

[0020] In the preferred embodiment, the vertical track, corner track, and ramp track are standard components made of high-strength alloy steel or stainless steel, which can be freely combined and used in three-dimensional space through connectors. Specifically, the connectors can be used for docking and lengthening installation according to the on-site usage requirements.

[0021] The method of using the three-in-one climbing ladder track based on the above climbing device includes the following steps:

[0022] S1: After installing the track system, ladder system and fall protection system according to the route, check whether each connection part of the ladder track is firm, and ensure that the first mounting plate, second mounting plate and third mounting plate are firmly connected to the mounting fasteners;

[0023] S2: When the climbing device is used to carry people, the passengers should wear full safety belts. Before starting, a momentary load test should be conducted on the clearance between the device and the climbing ladder track to ensure that it can withstand the weight within the specified range. When carrying people, the chest suspension point of the personnel's safety belt should be connected to the fall protection device. With both feet on the climbing device, the fall protection function of the climbing device should be released by both hands before the device is powered on and can be used.

[0024] S3: In an emergency, if the climbing device malfunctions and cannot be stopped, the operator should use both hands to activate the anti-fall device of the climbing device under the influence of gravity and inertia. This will safely brake the climbing device on the anti-fall guide rail and prevent it from falling.

[0025] S4: Emergency evacuation passage for personnel in vertical working conditions. In the event of a malfunction in vertical working conditions, passengers must not disconnect the connection between the chest suspension point of the seat belt and the fall protection device. Instead, they should climb up or down the first ladder bar to evacuate. Once they reach a safe area, they should disconnect the connection between the chest suspension point of the seat belt and the fall protection device to complete the emergency evacuation in vertical working conditions.

[0026] S5: Emergency evacuation passage for personnel in slope conditions. In the event of a malfunction in slope conditions, passengers should first connect the safety rope behind their seat belt to the fall protection device, then disconnect the safety belt from the chest suspension point and the fall protection device, and climb up or down the third ladder crossbar to evacuate. After reaching a safe area, disconnect the safety rope behind the seat belt from the fall protection device to complete the emergency evacuation in slope conditions.

[0027] S6: Emergency evacuation passage for personnel under various working conditions. Based on the layout of the three-in-one ladder track in the passage area, the corresponding evacuation passage can be rotated according to the current passage location of the passenger. During the evacuation, it is essential to ensure that one suspension point of the safety belt (chest attachment point or back safety rope) is connected to the fall arrest device to ensure the safe evacuation of the passenger.

[0028] The present invention provides a three-in-one climbing ladder track and its usage method that can support climbing devices in various environmental conditions. By adopting the above structure and method, the following beneficial effects are achieved:

[0029] (1) The design structure of the device is relatively simple, which makes production and installation easier and reduces the overall cost.

[0030] (2) It provides access solutions for workers in different working environments. Whether it is vertical climbing, sloping passage, or a combination of both, it can be quickly installed and deployed according to the specific conditions on site, demonstrating extremely high adaptability and flexibility.

[0031] (3) By combining the climbing device track system with the personnel climbing stairs, a seamless connection from the high-risk environment to the safe area is achieved, ensuring that even if the climbing equipment fails, personnel can evacuate quickly and safely;

[0032] (4) The device can be reused, which not only increases the product life cycle but also reduces replacement costs, and is in line with the concept of sustainable development. Attached Figure Description

[0058] Example 3:

[0059] Taking large-scale equipment maintenance at a hydropower station as an example, workers need to frequently move between multiple different heights within the station. Considering the limited space inside the power station and safety concerns regarding working at heights, the three-in-one climbing ladder track provided by this invention offers the following advantages:

[0060] Installation preparation phase

[0061] First, based on the actual environmental conditions inside the hydropower station, a complete three-in-one ladder track system was designed. This system comprises three parts: a vertical track section 11, a corner track section 12, and a ramp track section 13. All tracks are constructed using high-strength alloy steel or stainless steel, ensuring structural strength while reducing weight for easy installation and transportation.

[0062] Installation phase

[0063] Vertical rail 11 installation:

[0064] Where vertical climbing is required, first install the vertical section of track.

[0065] The track base support frame is fixed to the building or bracket and reinforced by fasteners 16. The rack 14 on the track is welded to the inside of the limiting track to facilitate the engagement of the drive gear of the climbing device 2; the fall arrest guide rail 15 is installed in the middle of the ladder crossbar 11-3 and is used in conjunction with the fall arrest braking system 3.

[0066] Installation of corner rail 12:

[0067] Angle track 12 is installed where the vertical track 11 connects to the horizontal or other angled track.

[0068] The corner track base support frame is also fixed in the appropriate position to ensure that the device can smoothly transition at the corner. The rack 14 and the anti-fall guide rail 15 on the corner track 12 are also installed in place to ensure that the device can operate safely at the corner.

[0069] Installation of ramp rail 13: For locations where ramp passage is required, ramp rail 13 shall be installed.

[0070] The foundation support frame of the inclined track is fixed on the inclined surface, and the installation method of the rack 14 and the anti-fall guide rail 15 is similar to that of the vertical section and the corner track.

[0071] When using:

[0072] S1: After installing the track system, ladder system and fall protection system according to the route, check whether each connection part of the ladder track is firm, and ensure that the first mounting plate, second mounting plate and third mounting plate are firmly connected to the mounting fasteners;

[0073] S2: When the climbing device is used to carry people, the passengers should wear full safety belts. Before starting, a momentary load test should be conducted on the clearance between the device and the climbing ladder track to ensure that it can withstand the weight within the specified range. When carrying people, the chest suspension point of the personnel's safety belt should be connected to the fall protection device. With both feet on the climbing device, the fall protection function of the climbing device should be released by both hands before the device is powered on and can be used.

[0074] S3: In an emergency, if the climbing device malfunctions and cannot be stopped, the operator should use both hands to activate the anti-fall device of the climbing device under the influence of gravity and inertia. This will safely brake the climbing device on the anti-fall guide rail and prevent it from falling.

[0075] S4: Emergency evacuation passage for personnel in vertical working conditions. In the event of a malfunction in vertical working conditions, passengers must not disconnect the connection between the chest suspension point of the seat belt and the fall protection device. Instead, they should climb up or down the first ladder bar to evacuate. Once they reach a safe area, they should disconnect the connection between the chest suspension point of the seat belt and the fall protection device to complete the emergency evacuation in vertical working conditions.

[0076] S5: Emergency evacuation passage for personnel in slope conditions. In the event of a malfunction in slope conditions, passengers should first connect the safety rope behind their seat belt to the fall protection device, then disconnect the safety belt from the chest suspension point and the fall protection device, and climb up or down the third ladder crossbar to evacuate. After reaching a safe area, disconnect the safety rope behind the seat belt from the fall protection device to complete the emergency evacuation in slope conditions.

[0077] S6: Emergency evacuation passage for personnel under various working conditions. Based on the layout of the three-in-one ladder track in the passage area, the corresponding evacuation passage can be rotated according to the current passage location of the passenger. During the evacuation, it is essential to ensure that one suspension point of the safety belt (chest attachment point or back safety rope) is connected to the fall arrest device to ensure the safe evacuation of the passenger.

[0078] The above embodiments, through an integrated track system, ensure the safety of operators while saving space and costs.
