Description

A rail-type lifting system Technical Field

[0001] This utility model demonstrates a rail-type lifting system, belonging to the technical field of lifting systems. Background Technology

[0002] Rail-mounted lifting systems are primarily used to address the mobility, toileting, and bathing needs of the elderly, those with mobility issues, and those unable to walk. They are widely applicable in hospitals, nursing homes, rehabilitation centers, and homes. Rail-mounted lifting systems are mainly nursing devices designed to assist disabled individuals with barrier-free movement, used for short-distance relocation and rehabilitation care for disabled individuals or patients.

[0003] Rail-mounted lifting systems typically include rails, trolleys that slide along the rails, and lifting mechanisms suspended from the trolleys. The lifting mechanism requires power during use. Existing rail-mounted lifting systems power the lifting mechanism by moving the lifting head to a designated area for charging to maintain normal operation. However, when the power is depleted during use, it is difficult to move the lifting mechanism to the charging area, resulting in wasted time and inconvenience. In addition, it can disrupt the transfer of disabled people and may cause safety accidents, posing significant safety hazards.

[0004] Another power supply method involves laying a power cable of the same length as the trolley's range of motion. In this method, the power cable is directly connected to the lifting mechanism, and it moves with the lifting mechanism, increasing the likelihood of damage. Furthermore, since the power cable is the same length as the track, a longer track will result in a longer power cable, increasing the cost of the track-type lifting system and making maintenance and replacement of the power cable more difficult. Additionally, the power cable being directly plugged into the outer surface of the lifting mechanism affects its aesthetics and poses certain safety hazards. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that the power supply method of the existing lifting mechanism affects the use of the lifting mechanism and poses safety hazards. To this end, a rail-type lifting system is provided, which can charge the lifting mechanism at any position on the entire rail.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A rail-mounted lifting system, comprising:

[0008] A power supply track, comprising a track and conductive elements laid along the track's extension direction;

[0009] A pulley, which is connected to a track and can slide in a direction defined by the track;

[0010] The lifting mechanism is suspended from the trolley via a detachable mechanical coupling device;

[0011] The trolley is equipped with a power-taking device, which includes a power-taking end and a female electrical coupler. The power-taking end maintains electrical contact with the conductive element when the trolley slides. The lifting mechanism has a male electrical coupler. The female electrical coupler and the male electrical coupler constitute a detachable electrical coupling device and are configured to be synchronously aligned to form an electrical connection when the detachable mechanical coupling device is connected.

[0012] The beneficial effects of using this utility model are:

[0013] In this invention, the conductive element is laid along the track extension direction. The trolley is equipped with a power-collecting device. During the trolley's sliding along the track, the power-collecting device maintains an electrical connection with the conductive element. When the lifting mechanism engages with the trolley, the male and female electrical couplers of the lifting mechanism abut against each other, thus maintaining an electrical connection. Therefore, the conductive element conducts electrical energy to the lifting mechanism through the power-collecting device and the male electrical coupler. The laying of the conductive element allows the lifting mechanism to be charged at any position on the track, preventing the lifting mechanism from running out of power during use and ensuring that the lifting mechanism is always charged. It also prevents forgetting to charge, making the lifting mechanism more convenient and worry-free to use. Furthermore, the lifting mechanism and the trolley are detachably connected via a detachable mechanical coupling device. The male and female electrical couplers constitute a detachable electrical coupling device. When connected in a detachable mechanical coupling device, the male and female electrical couplers are synchronously aligned to form an electrical connection, thus creating a conductive circuit. When the lifting mechanism separates from the trolley, the male electrical coupler also automatically separates from the female electrical coupler. The connection and separation of the male and female electrical couplers are synchronized with the engagement and separation of the lifting mechanism and the trolley, eliminating the need for manual operation by the user and greatly reducing the difficulty of electrical connection between the lifting mechanism and the trolley. Secondly, the conductive components are laid inside the track and are not directly exposed to the outside, which can reduce the possibility of safety accidents and help improve the safety of the lifting system. At the same time, the conductive components do not affect the appearance of the lifting system, giving it a high aesthetic appeal.

[0014] Preferably, the female electrical coupler includes a coupling end formed on the surface of the trolley housing, and the male electrical coupler contacts the coupling end to form an electrical connection.

[0015] Preferably, the male electrical coupler includes a conductive sheet with an elastic portion. When connected to the detachable mechanical coupling device, the elastic portion deforms, maintaining an electrical connection between the conductive sheet and the female electrical coupler. By employing the aforementioned technical solution, the elastic portion enhances the contact strength between the male and female electrical couplers, ensuring a stable electrical connection and reducing the likelihood of poor contact. This ensures a more stable and reliable power supply to the lifting mechanism. Furthermore, repeated disassembly and reassembly of the lifting mechanism and trolley may increase the assembly gap between them. The elastic portion ensures that the conductive sheet and the coupling end maintain an electrical connection even after this gap appears, effectively extending the service life of the lifting system.

[0016] Preferably, the bottom end of the elastic part is fixedly connected to the conductive sheet, the lifting mechanism is engaged with the trolley, the top end of the elastic part abuts against the coupling end, and the conductive sheet maintains an electrical connection with the coupling end through the elastic part.

[0017] Preferably, the female and male electrical couplers are electrically connected by a concave-convex fit.

[0018] Preferably, the power-taking end is elastically loaded by the reset member to maintain contact with the conductive element. Using the aforementioned technical solution, as the trolley slides along the track, the power-taking end also moves with the trolley. The elastic loading of the power-taking end by the reset member ensures that the power-taking end remains in contact with the conductive element, preventing it from separating from the conductive element due to trolley vibration. This maintains a good electrical connection between the trolley and the conductive element, ensuring a reliable power supply foundation for the lifting mechanism.

[0019] Preferably, the trolley has a strip-shaped hole, within which a pin is slidably mounted. The power-taking end is rotatably connected to the pin, and the power-taking end forms rolling contact with the conductive element. One end of the reset member abuts against the end of the strip-shaped hole away from the conductive element, and the other end abuts against the pin. The female end electrocoupler is electrically connected to the power-taking end through the pin. Using the aforementioned technical solution, the power-taking end can rotate freely around the pin. As the power-taking end slides along the track with the trolley, rolling friction is formed between the power-taking end and the conductive element, effectively reducing the frictional force between them and lowering the possibility of wear, thus helping to extend their service life. Furthermore, the rolling contact between the power-taking end and the conductive element reduces the resistance encountered during the trolley's sliding process, making the trolley's sliding more effortless and smoother.

[0020] Preferably, two conductive elements are spaced apart within the track. The power supply device includes two power-taking terminals and two female electrocouplers. The two power-taking terminals are in rolling contact with the two conductive elements, and the two female electrocouplers are laid along both ends of the shell in the length direction. The lifting mechanism is equipped with two male electrocouplers, and the trolley shell is equipped with two coupling terminals corresponding to the male electrocouplers. Using the aforementioned technical solution, the two conductive elements are connected to the positive and negative terminals of the power supply, respectively. The spaced arrangement of the two conductive elements avoids the possibility of short circuits between them, making the use of the conductive elements safer and more reliable.

[0021] Preferably, the track has two parallel grooves, and two conductive elements are respectively laid in the two grooves, with the power-taking end extending into the groove and maintaining electrical contact with the conductive element. Using the aforementioned technical solution, the two conductive elements are installed in the two grooves respectively, which separates the two conductive elements, preventing accidental contact and short circuits, thus reducing safety hazards. Furthermore, the grooves guide the power-taking end, allowing the trolley to slide more smoothly along the track.

[0022] Preferably, the conductive element is laid on the top wall inside the guide rail, and one end of the power-taking device extends to the top of the trolley and maintains electrical contact with the conductive element. By employing the aforementioned technical solution, laying the conductive element on the top wall inside the track can reduce the likelihood of debris adhering to the conductive element and causing direct conductivity between the two conductive elements, thus improving the safety of the lifting system.

[0023] Preferably, the conductive element is laid on the side wall inside the guide rail, and one end of the power taking device extends to the surface of the trolley and maintains electrical contact with the conductive element.

However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] As shown in Figures 1 to 6, this embodiment illustrates a track-type lifting system, including a power supply track 1, a trolley 2, and a lifting mechanism 3. The power supply track includes a track 1 and a conductive element 13 laid along the extension direction of the track 1. The trolley 2 is slidably connected to the track 1 and can slide along the direction defined by the track 1. The lifting mechanism 3 is suspended on the trolley 2 by a detachable mechanical coupling device. The trolley 2 is equipped with a power-taking device, which includes a power-taking end 221 and a female end electrical coupler 222. The power-taking end 221 maintains electrical contact with the conductive element 13 when the trolley 2 slides. The lifting mechanism 3 has a male end electrical coupler 31. The female end electrical coupler 222 and the male end electrical coupler 31 constitute a detachable electrical coupling device and are configured to synchronously align and form an electrical connection when the detachable mechanical coupling device is connected.

[0037] In this embodiment, the conductive element 13 is laid along the extension direction of the track 1. The trolley 2 is equipped with a power-collecting device. During the sliding process of the trolley 2 along the track 1, the power-collecting device always maintains an electrical connection with the conductive element 13. When the lifting mechanism 3 engages with the trolley 2, the male end electrical coupler 31 of the lifting mechanism 3 abuts against the female end electrical coupler 222 to maintain an electrical connection. Therefore, the conductive element 13 conducts electrical energy to the lifting mechanism 3 through the power-collecting device and the male end electrical coupler 31. The laying of the conductive element 13 allows the lifting mechanism 3 to be charged at any position on the track 1, avoiding the phenomenon of the lifting mechanism 3 running out of power during use, ensuring that the lifting mechanism 3 is always in a charged state, and also preventing the phenomenon of forgetting to charge, making the use of the lifting mechanism 3 more convenient and worry-free. In addition, the lifting mechanism 3 and the trolley 2 are detachably connected by a detachable mechanical coupling device. The male electrical coupler 31 and the female electrical coupler 222 constitute a detachable electrical coupling device. When the detachable mechanical coupling device is connected, the male electrical coupler 31 and the female electrical coupler 222 are synchronously aligned to form an electrical connection, thereby forming a conductive circuit. When the lifting mechanism 3 is separated from the trolley 2, the male electrical coupler 31 is also automatically separated from the female electrical coupler 222. The conduction and separation of the male electrical coupler 31 and the female electrical coupler 222 are carried out synchronously with the engagement and separation of the lifting mechanism 3 and the trolley 2, without the need for manual operation by the user, which greatly reduces the difficulty of electrical connection between the lifting mechanism 3 and the trolley 2. Secondly, the conductive element 13 is laid inside the track 1 and is not directly exposed to the outside, which can reduce the possibility of safety accidents and help improve the safety of the lifting system. At the same time, the conductive element 13 will not affect the appearance of the lifting system, making the lifting system more aesthetically pleasing.

[0038] As shown in Figures 1 to 4, in this embodiment, the bottom of the track 1 is provided with an opening for the trolley 2 to extend into. Slides 11 are laid along the two sides of the opening. Two rollers 21 are rotatably connected to the top of the trolley 2. The rollers 21 are placed on the slides 11 and can slide along the slides 11. Two conductive elements 13 are laid at intervals inside the track 1. The two conductive elements 13 correspond to the positive and negative terminals respectively. An adapter 14 is provided at the end of the track 1 and is electrically connected to the two conductive elements 13. The adapter 14 includes a power plug. When the track 1 is installed, the adapter 14 is plugged into a power socket through the power plug so that the conductive elements 13 inside the track 1 are directly electrically connected to the power supply, so that the conductive elements 13 are kept in a charged state.

[0039] As shown in Figure 3, the power-taking device in this embodiment includes a power-taking end 221 and a female-end electrical coupler 222. The housing of the trolley 2 has a strip-shaped hole 23, within which a pin 25 is slidably mounted. The pin 25 is a conductor, and the power-taking end 221 is a conductive wheel. The power-taking end 221 is rotatably connected to one end of the pin 25. The female-end electrical coupler 222 is fixed to the other end of the pin 25 by bolts. The pin 25 maintains electrical connection between the power-taking end 221 and the female-end electrical coupler 222. The strip 23 slides along its length to move the power-taking end 221 closer to or away from the conductive element 13. A reset element 24, a compression spring, is also installed inside the strip 23. One end of the reset element 24 abuts against the end of the strip 23 away from the conductive element 13, and the other end abuts against the pin 25. The elastic force of the reset element 24 acts on the pin 25, causing the pin 25 to slide towards the end of the strip 23 closer to the conductive element 13. Under the action of the pin 25, the power-taking end 221 maintains its position relative to the conductive element 13. As the conductive element 13 moves against the trolley 2, the power-taking end 221 also moves with the trolley 2. The reset member 24 provides elastic loading to the power-taking end 221, ensuring that the power-taking end 221 always remains in contact with the conductive element 13. This prevents the power-taking end 221 from separating from the conductive element 13 due to the vibration of the trolley 2, maintaining a good electrical connection between the trolley 2 and the conductive element 13, and ensuring that the lifting mechanism 3 has a reliable power supply foundation. In addition, the power-taking end 221 can rotate freely around the pin 25. During the process of the power-taking end 221 sliding along the track 1 with the trolley 2, rolling friction is formed between the power-taking end 221 and the conductive element 13, which can effectively reduce the frictional force between the power-taking end 221 and the conductive element 13, reduce the possibility of wear on the power-taking end 221 and the conductive element 13, and help extend the service life of the power-taking end 221 and the conductive element 13. Furthermore, the rolling contact between the power-taking end 221 and the conductive element 13 can reduce the resistance encountered by the trolley 2 during the sliding process, making the sliding of the trolley 2 more effortless and smooth.

[0040] As shown in Figures 2 and 3, in this embodiment, the top wall of the inner side of the track 1 is provided with two parallel sliding grooves 12. The sliding grooves 12 are open downwards, and two conductive elements 13 are respectively laid in the two sliding grooves 12. The power taking end 221 is installed on the top of the trolley 2, and the power taking end 221 has an upward sliding tendency under the elastic loading of the reset member 24. After the trolley 2 is connected to the track 1, the top of the power taking end 221 extends into the sliding groove 12 and contacts the roller 21 of the conductive element 13. The power taking device includes two power taking ends 221 and two female electrical couplers 222, wherein the two power taking ends 221 are respectively arranged at both ends in the width direction of the trolley 2, and the two power taking ends 221 extend into the two sliding grooves respectively. Within 12, the two power-taking terminals 221 correspond to the positive and negative terminals of the power supply, respectively. In this embodiment, the two conductive elements 13 are respectively installed in the two sliding grooves 12. The sliding grooves 12 can separate the two conductive elements 13, preventing accidental contact and short circuit, thus reducing safety hazards. In addition, laying the conductive elements 13 on the top wall inside the track 1 can also reduce the amount of debris adhering to the conductive elements 13, which could cause the two conductive elements 13 to conduct directly, thus improving the safety of the lifting system. Furthermore, the power-taking terminals 221 extend into the sliding grooves 12, which can guide the power-taking terminals 221, thereby making the trolley 2 slide more smoothly along the track 1.

[0041] It should be noted that the conductive element 13 is a flexible conductive tape, which includes an insulating layer, a conductive layer and a protective layer. The conductive layer is located between the insulating layer and the protective layer. When the conductive element 13 is in the groove 12, the insulating layer is close to the groove wall of the groove 12 away from the groove opening, and the protective layer is close to the groove opening of the groove 12.

[0042] It is understandable that in other embodiments, the conductive element 13 may also be laid on the side wall inside the track 1, one end of the power taking device extends to the surface corresponding to the trolley 2 and keeps in contact with the conductive element 13, the two conductive elements 13 may be arranged on the same side of the guide rail track 1, or the two conductive elements 13 may be arranged on the two sides inside the track 1 respectively.

[0043] As shown in Figures 5 and 6, in this embodiment, the housing of the trolley 2 has two strip-shaped holes 23, which are located near the two ends of the trolley 2 along its length. Female electrical couplers 222 are installed inside the housing of the trolley 2, extending downwards along both ends of the housing along its length. The bottom of the trolley 2 has two coupling ends 223. The ends of the two female electrical couplers 222 furthest from the power-taking end 221 are connected to the two coupling ends 223, ensuring an electrical connection between the power-taking device and the coupling ends 223. Since the female electrical couplers 222 are located inside the trolley 2 and are not directly exposed to the surface of the trolley 2, the housing of the trolley 2 can protect the female electrical couplers 222, reducing... The reduced likelihood of damage to the female electrical coupler 222 also lowers the possibility of electric shock accidents caused by the female electrical coupler 222, thus improving the safety of the lifting system. In addition, concealing the female electrical coupler 222 inside the trolley 2 also improves the aesthetics of the trolley 2. Furthermore, with the two power take-up terminals 221 and the two female electrical couplers 222 located at opposite ends of the length of the trolley 2, the distance between the two power take-up terminals 221 and the two female electrical couplers 222 can be effectively increased, preventing short circuits caused by misunderstandings between the two power take-up terminals 221 or the two female electrical couplers 222. This makes the current conduction of the power take-up device safer and more reliable, contributing to the improved safety of the lifting system.

[0044] As shown in Figures 5 and 6, the lifting mechanism 3 in this embodiment includes a main unit and a boom. A winch and a drive motor for rotating the winch are rotatably connected inside the main unit. A traction belt is wound around the winch, extending from the bottom of the main unit and connected to the boom. The drive motor drives the winch to rotate, thereby controlling the release and retraction of the traction belt to control the lowering and raising of the boom. The male-end electrical coupler 31 includes a conductive sheet 312 with an elastic portion 311. The conductive sheet 312 is fixed to the top of the lifting mechanism 3, and the elastic portion 311 is a spring fixed to the conductive sheet 312. After the lifting mechanism 3 engages with the trolley 2, the elastic portion 311 is compressed by the coupling end 223 at the bottom of the trolley 2 and remains in contact with the coupling end 223. The conductive sheet 312 is connected to the coupling end through the elastic portion 311. 223 Maintains electrical connection. At this time, the conductive element 13, the power taking device, and the male electrical coupler 31 form a conductive circuit, so that the power supply can stably and continuously provide power to the lifting mechanism 3. The elastic part 311 can enhance the contact force between the male electrical coupler 31 and the power taking device, ensuring the electrical connection between the male electrical coupler 31 and the female electrical coupler 222, reducing the possibility of poor contact between the male electrical coupler 31 and the female electrical coupler 222, and ensuring a more stable and reliable power supply to the lifting mechanism 3. In addition, after the lifting mechanism 3 and the trolley 2 are disassembled and assembled repeatedly over a long period of time, the assembly gap between the lifting mechanism 3 and the trolley 2 may increase. The elastic part 311 can ensure that the conductive piece 312 and the power taking device still maintain electrical connection after the assembly gap occurs, thereby effectively extending the service life of the lifting system.

[0045] It is understandable that in other embodiments, the elastic part 311 may also be fixed between the conductive sheet 312 and the housing of the lifting mechanism 3. The elastic part 311 acts on the conductive sheet 312, causing the conductive sheet 312 to have an upward movement tendency. When the lifting mechanism 3 is engaged with the trolley 2, the coupling end 223 at the bottom of the trolley 2 directly abuts against the conductive sheet 312, and the elastic part 311 is compressed through the conductive sheet 312. The conductive sheet 312 abuts against the coupling end 223 so that the conductive sheet 312 and the power taking device of the trolley 2 are electrically connected.

[0046] It is understandable that in other embodiments, the conductive sheet 312 and the elastic part 311 are an integral structure, that is, the conductive sheet 312 is an elastic metal sheet. When the lifting mechanism 3 is engaged with the trolley 2, the coupling end 223 at the bottom of the trolley 2 directly abuts against the elastic metal sheet, and the elastic metal sheet undergoes elastic deformation.

[0047] It is understandable that in other embodiments, the male electrical coupler 31 and the female electrical coupler 222 can also form an electrical connection through a concave-convex fit. That is, one of the male electrical coupler 31 and the female electrical coupler 222 is provided with a groove, and the other is provided with a protrusion. When the lifting mechanism 3 is engaged with the trolley 2, the protrusion extends into the groove and remains in contact, thereby forming an electrical connection.

[0048] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
