Description

Technical Field

[0001] This utility model belongs to the field of conveying equipment technology, specifically relating to a single-track lifting conveying device. Background Technology

[0002] To facilitate daily life, various elevators have emerged. Patent CN218893348U discloses a lifting device. While this device can help people go up and down stairs, its application is limited; for example, it cannot transport wheelchair users, and the overall utilization rate of the equipment is low. Therefore, a single-rail lifting and conveying device is needed to solve the aforementioned technical problems. Utility Model Content

[0003] To address the aforementioned deficiencies in the existing technology, this utility model provides a single-track lifting and conveying device, including a slide rail and a sliding assembly mounted on the slide rail. The sliding assembly is connected to a vertical rod, and a lifting assembly is mounted on the vertical rod. The slide rail, sliding assembly, and vertical rod respectively adopt the slide rail, sliding assembly, and connecting component two in the lifting device disclosed in CN218893348U, that is, the vertical rod is equivalent to the connecting component two in CN218893348U.

[0004] The lifting assembly includes a support rod, a push rod, and a lifting rope. The support rod, push rod, and vertical rod form a triangular support. One end of the lifting rope is located at the connection between the support rod and the push rod, and the other end of the lifting rope is connected to a hook.

[0005] It should be noted that the supports mounted on the vertical rod provide support for the lifting rope. The rope, along with the hook, can lift objects, seats, or wheelchairs off the ground, allowing them to move along the sliding rails with the sliding components, thus achieving a transport function. The lifting capabilities are diverse, encompassing applications such as wheelchairs, furniture, and even small vehicle lifting. This versatility attracts more users, generating a Pareto effect and achieving optimal resource allocation and maximized efficiency.

[0006] Preferably, one end of the support rod is hinged to the vertical rod, the other end of the support rod is hinged to one end of the push rod, and the other end of the push rod is hinged to the vertical rod below the support rod. The push rod is an electric push rod or a hydraulic rod.

[0007] It should be noted that the support can be retracted by extending and retracting the push rod, reducing the space occupied when not in use. In use, the hook is first attached to the object to be lifted, and then the push rod extends continuously. The hinged end between the support rod and the push rod moves further away from the vertical rod and rises, forming an unfolded triangular shape that lifts the object off the ground. This design offers high space utilization.

[0008] Preferably, at least two sliding components are provided, and adjacent sliding components are connected by a spring rod (elastic connecting rod) or a universal joint. This doubles the carrying capacity.

[0009] It should be noted that increasing the number of sliding components can increase the amount of transported objects. The use of spring rods or universal joints allows the connected sliding components to smoothly pass through bends in the slide rail. Using spring rods to connect the sliding components not only effectively prevents derailment but also doubles the transport capacity. During operation, the spring rods can adaptively adjust according to the condition of the slide rail and the operating forces, ensuring that the sliding components remain firmly connected to the slide rail even in complex operating environments, laying the foundation for efficient and safe operation.

[0010] Preferably, the vertical rods connecting two adjacent sliding components are respectively provided with a lifting component and a pedal.

[0011] It should be noted that one end of the pedal is hinged to the lower end of the vertical rod. A limiter, which is a triangular iron, is provided at the hinge point between the pedal and the vertical rod, allowing the pedal to rotate upwards around the hinge point and retract. During use, the pedal is horizontal, making it easy for a person to step on it. The combination of the pedal and the lifting assembly allows adjacent sliding components to transport different objects, expanding its application range. This setup integrates some functions of a lift, crane, stair climber, and ordinary elevator. Taking an older residential community as an example, it not only helps residents with mobility impairments easily go up and down stairs but can also lift wheelchairs, small furniture, and other items, greatly improving the overall utilization rate of the equipment, meeting the needs of diverse scenarios, and effectively solving the dilemma of traditional single-function equipment being unable to cope with complex needs.

[0012] Preferably, the sliding assembly is further provided with a ratchet, which engages with a rack on the slide rail, and the ratchet is engaged with a stop pawl, which is connected to a pull rope.

[0013] It should be noted that the ratchet setting can prevent the sliding component from sliding downhill when the slide rail is on an uphill slope, thus improving safety. When the sliding component needs to slide downhill, pull the pull rope to move the stop pawl away from the ratchet. Under the action of gravity, the sliding component slides down. When it slides to the desired position, release the pull rope, and the stop pawl will contact the ratchet to lock the ratchet, stopping the sliding component from sliding downhill.

[0014] Preferably, the lower part of the vertical rod is also provided with a second hook.

[0015] It should be noted that after the object is suspended a certain distance, it can be hung on hook two. Both hook one and hook two play a role in fixing the object, improving the stability of the object when it moves with the sliding component, and making it safer.

[0016] Preferably, the vertical rod is equipped with two lifting components to increase the quantity that can be transported.

[0017] Working principle: A bracket mounted on a vertical rod supports the suspension rope. The rope, along with a hook, lifts an object, chair, or wheelchair off the ground, allowing it to move along a slide rail with the sliding components, thus achieving a transport function. Increasing the number of sliding components increases the transport capacity. Spring rods or universal joints allow connected sliding components to smoothly pass through turns on the slide rail. Applications include scenic areas and staircases.

[0018] This utility model also includes other components that enable the normal operation of a single-rail lifting conveyor, such as motor control components, electric push rod control components, and hydraulic rod control components, all of which are conventional technologies in the field. Furthermore, devices or components not limited in this utility model, such as ratchet, stop pawl, universal joint, and spring rod, all employ conventional technologies and equipment in the field.

[0019] The advantages of this utility model are: it facilitates transportation, allows for the diversification of transportation objects and application scenarios, has high space utilization, and improves the reliability and efficiency of transportation. Attached Figure Description

[0032] The present invention will now be clearly described with reference to the accompanying drawings and specific embodiments. This description is merely for explaining the present invention and is not intended to limit it. Any modifications, equivalent substitutions, improvements, etc., made by those skilled in the art based on the embodiments of the present invention without inventive effort to obtain all other embodiments should be included within the protection scope of the present invention.

[0033] Example 1

[0034] like Figure 1-6 As shown in Figures 9 and 10, this embodiment provides a single-track lifting conveyor device, including a slide rail 8 and a sliding component 1 disposed on the slide rail 8. The sliding component 1 is connected to a vertical rod 2, and a lifting component is provided on the vertical rod 2. The slide rail, the sliding component, and the vertical rod are respectively adopted from the slide rail, the sliding component, and the connecting part 2 in the lifting device disclosed in CN218893348U, that is, the vertical rod is equivalent to the connecting part 2 in CN218893348U.

[0035] The lifting assembly includes a support rod 3, a push rod 6, and a lifting rope 4. The support rod 3 and push rod 6, together with the vertical rod 2, form a triangular support. One end of the lifting rope 4 is located at the connection between the support rod 3 and the push rod 6, and the other end of the lifting rope 4 is connected to a hook 5. The support on the vertical rod 2 supports the lifting rope 4. The lifting rope 4 and hook 5 can lift objects, seats, or wheelchairs 9 off the ground, allowing them to move along the slide rail 8 with the sliding assembly 1, thus achieving a conveying function. The lifting capabilities are diverse, including applications such as lifting wheelchairs 9, furniture, and even small vehicles. This versatility attracts more users, generates a Pareto effect, and achieves optimal resource allocation and maximized efficiency.

[0036] One end of the support rod 3 is hinged to the vertical rod 2, and the other end of the support rod 3 is hinged to one end of the push rod 6. The other end of the push rod 6 is hinged to the vertical rod 2 below the support rod 3. The push rod 6 can be an electric push rod or a hydraulic rod. The support can be retracted by extending and retracting the push rod 6, reducing the space occupied when not in use. When in use, the hook 5 is first hung with the object to be lifted, and then the push rod 6 extends continuously. The hinged end of the support rod 3 and the push rod 6 moves away from the vertical rod 2 and rises, and the support is in an unfolded triangular state, lifting the object off the ground. This method offers high space utilization.

[0037] Two sliding components 1 are provided, connected by a spring rod 10 (elastic connecting rod) or a universal joint 11. This doubles the carrying capacity. Increasing the number of sliding components 1 increases the amount of objects that can be transported. The spring rod 10 or universal joint 11 allows the connected sliding components 1 to smoothly pass through the turns of the slide rail 8. Using a spring rod 10 to connect the sliding components 1 not only effectively prevents derailment but also doubles the carrying capacity. During operation, the spring rod 10 can adaptively adjust according to the condition of the slide rail 8 and the operating force, ensuring that the sliding components 1 remain firmly connected to the slide rail 8 even in complex operating environments, laying the foundation for efficient and safe operation.

[0038] Two sliding components 1 are connected to a vertical rod 2, each equipped with a lifting component and a pedal. One end of the pedal is hinged to the lower end of the vertical rod 2. A limiter, a triangular iron 16, is provided at the hinge point between the pedal 15 and the vertical rod 2, allowing the pedal to rotate upwards around the hinge point and retract. During use, the pedal is horizontal, making it easy for a person to step on it. The pedal and lifting component allow adjacent sliding components 1 to transport different objects, expanding its application range. This setup integrates some functions of a lift, crane, stair climber, and ordinary elevator. Taking an older residential community as an example, it not only helps residents with mobility impairments easily go up and down stairs but can also lift wheelchairs 9, small furniture, and other items, greatly improving the overall utilization rate of the equipment, meeting the needs of diverse scenarios, and effectively solving the dilemma of traditional single-function equipment being unable to cope with complex needs.

[0039] Since the slide rail and sliding assembly adopt the slide rail and sliding assembly disclosed in CN218893348U, the upper chuck in CN218893348U can be replaced with an upper roller, and directional chucks can be provided on both sides. The directional chucks are made of nylon wheels to reduce noise. When the nylon wheels contact the slide rail 8, they can effectively buffer vibration and reduce friction noise, creating a quiet and comfortable riding environment for passengers.

[0040] The two forward and reverse motors connected to the two sliding components can have different power ratings, with the larger motor located on the uphill sliding component. The downhill component is called the first sliding component, and the uphill component is called the tail sliding component. When going uphill, the first and tail sliding components operate in tandem. When going downhill, only the first sliding component is powered. The forward and reverse motors are connected to the mains power supply via a pantograph, which is diamond-shaped for more stable and efficient power delivery. This eliminates the traditional battery power supply mode, overcoming the limitations of battery load capacity and expanding the geographical scope of equipment use. The pantograph directly receives 220V mains power and rectifies it to 24V DC. This improvement frees the elevator from limitations imposed by battery charge, lifespan, and charging cycles, significantly improving power supply stability and preventing operational failures due to battery issues. Furthermore, mains power supply is relatively inexpensive, effectively reducing the later maintenance costs of the equipment.

[0041] The lower part of the vertical rod 2 is also provided with hook 2 7. When the object is lifted a certain distance, it can be hung on hook 2 7. Both hook 1 5 and hook 2 7 play a role in fixing the object, improving the stability of the object when it moves with the sliding component 1, and making it safer.

[0042] The vertical rod 2 is equipped with two lifting components to increase the amount of cargo that can be transported.

[0043] Example 2

[0044] like Figure 7-10 As shown, the difference between this embodiment and Embodiment 1 is that the sliding assembly is further provided with a ratchet 12, which engages with a rack on the slide rail. The ratchet 12 is engaged with a stop pawl 13, and the stop pawl 13 is connected to a pull rope 14. The forward and reverse motor of the sliding assembly is connected to a clutch. The ratchet 17, without affecting the movement of the sliding assembly along the slide rail, can prevent the sliding assembly 1 from sliding downhill when the slide rail 8 is uphill, thus improving safety. When the sliding assembly 1 needs to go downhill, the clutch disengages, the forward and reverse motor stops working, and the pull rope is pulled to move the stop pawl away from the ratchet. Under the action of gravity, the sliding assembly slides down the slide rail 8. When it slides to the desired position, the pull rope is released, the stop pawl contacts the ratchet, and the ratchet is locked, stopping the sliding assembly 1 from sliding downhill.

[0045] In another embodiment, the sliding assembly is braked via a reducer and a ratchet.

[0046] Based on the above embodiments, the applicable scenarios for this application include: 1. Renovation of old buildings to improve residents' quality of life: The installation process is simple and does not require large-scale modifications to the building structure.

[0047] 2. Assisting wheelchair access and improving service efficiency in public places: In public places such as hospitals, train stations, docks, and airports, wheelchair users can directly use this chairlift without transferring. This feature effectively improves travel efficiency, reduces the burden on staff in carrying wheelchairs, enhances the service image of the venue, and provides more considerate and efficient services for travelers and patients with mobility impairments.

[0048] 3. Tourism and sightseeing facilities, expanding the service boundaries of scenic areas: These chairlifts can be installed along hillsides and trails within scenic areas, allowing tourists to enjoy nature and sightseeing in a safe and comfortable environment. For tourists with mobility issues who still desire to appreciate natural scenery, this facility provides equal opportunities. Introducing this chairlift to a scenic area can expand its service scope, improve service quality, attract more tourists, and drive economic growth.

[0049] 4. Upgrading personnel transport vehicles in smart mines to ensure safe production: This effectively reduces the accident rate during underground mine passage. In the complex underground environment, it reliably improves personnel transportation efficiency, providing strong support for safe production and efficient operation of the mine.

[0050] 5. Application in plastic greenhouses to improve agricultural production efficiency: Workers can move quickly inside plastic greenhouses using this device and work in conjunction with automated agricultural equipment, such as automatic irrigation and fertilization systems. This greatly improves work efficiency, reduces labor costs, and helps agricultural production move towards automation and intelligence.

[0051] 6. Industrial and Mining Workshops and Warehousing Applications, Driving Industrial Intelligent Upgrading: In industrial and mining workshops, this device helps workers quickly reach different work areas to perform tasks such as material handling and equipment maintenance, and works collaboratively with automated material handling robots. In warehousing scenarios, workers can use this conveyor system to move between shelves, working in conjunction with warehouse management systems and automated sorting robots to complete operations such as inventory counting, shelving, and descrambling, significantly improving the level of intelligent warehouse management and promoting the in-depth development of Industry 4.0.

[0052] The embodiments of this utility model have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
