Description

Technical Field

[0001] This utility model relates to the field of transportation equipment technology, and in particular to a lifting and carrying device and a transfer device. Background Technology

[0002] Backpack air conditioners play an irreplaceable role as a key heat dissipation device for electrical control cabinets. They not only effectively reduce the operating temperature of the control cabinet and ensure the normal operation of internal components, but also effectively block external dust, reduce dust accumulation inside the control cabinet, and reduce the difficulty of cleaning and insect prevention.

[0003] Because backpack air conditioners experience a significant performance decline and increased failure rate after prolonged use, they need to be disassembled regularly for maintenance and upkeep to ensure their proper functioning.

[0004] However, during the repair and replacement of backpack air conditioners, due to their large size and weight, and the fact that some backpack air conditioners are installed in complex locations at high heights, manual disassembly and assembly are difficult, the risk factor is high, and the efficiency of maintenance and upkeep is low.

One end of the first connector passes through the first slot and is threadedly connected to the first adjustment plate. The other end of the first connector abuts against the surface of the gimbal plate opposite to the first adjustment plate. One end of the second connector passes through the second slot and is threadedly connected to the second adjustment plate. The other end of the second connector abuts against the surface of the gimbal plate opposite to the second adjustment plate.

[0011] Optionally, the gimbal plate is further provided with a first connecting slot and a second connecting slot. The first connecting slot extends along the second direction and is used to connect multiple first slots. The second connecting slot extends along the third direction and is used to connect multiple second slots.

[0012] Optionally, the lifting assembly includes two sets of scissor lift modules, multiple connecting rods, and a lifting drive component. The two sets of scissor lift modules are spaced apart between the chassis and the gimbal plate along the third direction. The multiple connecting rods are connected between the two sets of scissor lift modules. One end of the lifting drive component is connected to the chassis, and the other end is connected to the connecting rod adjacent to it, so as to provide the two sets of scissor lift modules with a driving force to drive the gimbal plate to move up and down along the first direction.

[0013] Optionally, the scissor lift module includes a first scissor lift arm and a second scissor lift arm hinged at the midpoint. The first scissor lift arm is located outside the second scissor lift arm. One end of the first scissor lift arm near the chassis is slidably connected to the chassis along the second direction.

One end of the second scissor lift arm near the gimbal plate is slidably connected to the gimbal plate along the second direction. The connecting rod connected to the lifting drive component is connected to the first scissor lift arm.

[0014] Optionally, the scissor lift module includes a first guide rail, a second guide rail, a first roller, and a second roller. The first guide rail corresponds one-to-one with the first scissor lift arm and is connected to the chassis. The second guide rail corresponds one-to-one with the second scissor lift arm and is connected to the gimbal plate. The first roller is connected to the end of the first scissor lift arm near the chassis and is rotatably disposed within the first guide rail.

[0020] This utility model provides a lifting and supporting device. This device features a retractable lifting component along a first direction, allowing a gimbal plate connected to the lifting component to rise and fall relative to the chassis along the first direction under the drive of the lifting component. This enables the device to support backpack air conditioners of varying weights and heights during disassembly and assembly, reducing the difficulty of manual disassembly and assembly and improving efficiency. Furthermore, the gimbal plate has multiple first slots arranged sequentially along a second direction and multiple second slots arranged sequentially along a third direction. This allows for the adjustment of the area enclosed by the first adjustment plate, second adjustment plate, and fixing plate by inserting a first adjustment plate into any of the first slots and a second adjustment plate into any of the second slots. This allows for the limiting and fixing of backpack air conditioners of different sizes, preventing swaying during lifting and lowering, thereby improving safety and reducing the risk factor during disassembly and assembly.

[0021] This utility model provides a transfer device that, by applying the aforementioned lifting and bearing device, not only has the function of transfer and conveying, but also has the ability to assist in disassembly and assembly operations. Attached Figure Description

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0036] Because backpack air conditioners are large in size and weight, and some backpack air conditioners are installed in complex locations at high heights, manual disassembly and assembly are difficult, dangerous, and inefficient. Therefore, this embodiment provides a lifting and supporting device.

[0037] like Figures 1 to 6 As shown, the lifting and supporting device is connected to the chassis 1 and includes a lifting assembly 2 and a gimbal assembly 3. The lifting assembly 2 is telescopically mounted on the chassis 1 along a first direction. The gimbal assembly 3 includes a gimbal plate 31, a fixing plate 32, a first adjusting plate 33, and a second adjusting plate 34. The gimbal plate 31 is connected to the end of the lifting assembly 2 away from the chassis 1. The gimbal plate 31 has multiple first slots 311 arranged sequentially along a second direction and multiple second slots 312 arranged sequentially along a third direction. The first adjusting plate 33 can be selectively inserted into any of the first slots 311, and the second adjusting plate 34 can be selectively inserted into any of the second slots 312. The fixing plate 32 is connected to the gimbal plate 31 and is arranged opposite to the first adjusting plate 33 along the second direction.

[0038] This lifting and supporting device features a retractable lifting component 2 along a first direction. This allows the gimbal plate 31 connected to the lifting component 2 to rise and fall relative to the chassis 1 along the first direction under the influence of the lifting component 2. This enables the device to support backpack air conditioners of varying weights and heights during disassembly and assembly, reducing the difficulty of manual disassembly and assembly and improving efficiency. Furthermore, the gimbal plate 31 has multiple first slots 311 arranged sequentially along a second direction and multiple second slots 312 arranged sequentially along a third direction. This allows the size of the area enclosed by the first adjustment plate 33, the second adjustment plate 34, and the fixing plate 32 to be adjusted by inserting a first adjustment plate 33 into any first slot 311 and a second adjustment plate 34 into any second slot 312. This allows for the limiting and fixing of backpack air conditioners of different sizes, preventing swaying during lifting and lowering, thus improving safety and reducing the risk factor during disassembly and assembly.

[0039] In this embodiment, as Figure 3 As shown, the gimbal assembly 3 also includes an elastic rope hook 35, which is connected to the side of the gimbal plate 31 where the fixing plate 32 is located. By connecting the elastic rope hook 35 to the gimbal plate 31, the lifting and carrying device can be pulled by a traction rope when carrying a large object. The object can also be connected to the elastic rope hook 35 by a rope or strap. The elasticity of the elastic rope hook 35 and the tension of the rope are used to fix some large or irregularly shaped objects that are difficult to place on the lifting and carrying device, so that the object is more stably connected to the lifting and carrying device, preventing the object from shaking or slipping during transportation and ensuring transportation safety.

[0040] Optionally, such as Figures 3 to 6 As shown, the gimbal assembly 3 also includes a first connector 36 and a second connector 37. One end of the first connector 36 passes through the first slot 311 and is threadedly connected to the first adjustment plate 33. The other end of the first connector 36 abuts against the surface of the gimbal plate 31 away from the first adjustment plate 33. One end of the second connector 37 passes through the second slot 312 and is threadedly connected to the second adjustment plate 34. The other end of the second connector 37 abuts against the surface of the gimbal plate 31 away from the second adjustment plate 34.

[0041] One end of the first connector 36 passes through the first slot 311 and is threadedly connected to the first adjustment plate 33, while the other end abuts against the surface of the gimbal plate 31 opposite to the first adjustment plate 33. This allows the locking or unlocking of the first adjustment plate 33 and the gimbal plate 31 to be achieved simply by turning the first connector 36. One end of the second connector 37 passes through the second slot 312 and is threadedly connected to the second adjustment plate 34, while the other end abuts against the surface of the gimbal plate 31 opposite to the second adjustment plate 34. This allows the locking or unlocking of the second adjustment plate 34 and the gimbal plate 31 to be achieved simply by turning the second connector 37. This facilitates the adjustment of the positions of the first adjustment plate 33 and the second adjustment plate 34, so that the area enclosed by the first adjustment plate 33, the second adjustment plate 34, and the fixing plate 32 can be adjusted according to the size of the backpack air conditioner.

[0042] In this embodiment, both the first connector 36 and the second connector 37 are bolts. Threaded holes are provided on the surfaces of the first adjusting plate 33 and the second adjusting plate 34 that abut against the gimbal plate 31, so that the first connector 36 is threadedly connected to the first adjusting plate 33 and the second connector 37 is threadedly connected to the second adjusting plate 34.

[0043] Optionally, such as Figure 3 , Figure 5 , Figure 6 As shown, the gimbal plate 31 is also provided with a first connecting groove 313 and a second connecting groove 314. The first connecting groove 313 extends along the second direction and is used to connect multiple first slots 311. The second connecting groove 314 extends along the third direction and is used to connect multiple second slots 312.

[0044] By opening a first connecting groove 313 on the gimbal plate 31 to connect multiple first slots 311, when it is necessary to adjust the position of the first adjusting plate 33, it is only necessary to screw the first connector 36 until a gap appears between the first connector 36 and the gimbal plate 31. By moving the first adjusting plate 33, the first adjusting plate 33 drives the first connector 36 to slide in the first connecting groove 313 into the corresponding first slot 311, and the position adjustment of the first adjusting plate 33 can be completed without completely separating the first connector 36 from the first adjusting plate 33. By opening a second connecting groove 314 on the gimbal plate 31 to connect multiple second slots 312, when it is necessary to adjust the position of the second adjustment plate 34, it is only necessary to screw the second connector 37 until a gap appears between the second connector 37 and the gimbal plate 31. By moving the second adjustment plate 34, the second connector 37 is slid into the corresponding second slot 312 within the second connecting groove 314, thus completing the position adjustment of the second adjustment plate 34 without completely separating the second connector 37 from the second adjustment plate 34.

[0045] The position of the first connecting groove 313 can be freely adjusted according to requirements. It can be set at both ends of the multiple first slots 311 along a third direction to achieve communication between the multiple first slots 311, or it can be set in the middle of the multiple first slots 311 to achieve communication between the multiple first slots 311. In this embodiment, the first connecting groove 313 is set at the end of the first slot 311 along a third direction to achieve communication between the multiple first slots 311.

[0046] The position of the second connecting groove 314 can be freely adjusted according to requirements. It can be set at both ends of the multiple second slots 312 along the second direction to achieve communication between the multiple second slots 312, or it can be set in the middle of the multiple second slots 312 to achieve communication between the multiple second slots 312. In this embodiment, the second connecting groove 314 is set at the end of the second slot 312 along the second direction to achieve communication between the multiple second slots 312.

[0047] Optionally, such as Figure 2 As shown, the lifting assembly 2 includes two sets of scissor lift modules 21, multiple connecting rods 22, and a lifting drive component 23. The two sets of scissor lift modules 21 are connected at intervals between the chassis 1 and the gimbal plate 31 along a third direction. The multiple connecting rods 22 are connected between the two sets of scissor lift modules 21. One end of the lifting drive component 23 is connected to the chassis 1, and the other end is connected to the connecting rod 22 adjacent to it, so as to provide the two sets of scissor lift modules 21 with the driving force to drive the gimbal plate 31 to rise and fall along the first direction.

[0048] By setting two sets of scissor lift modules 21 connected at intervals along a third direction between the chassis 1 and the gimbal plate 31, this layout allows the entire lifting assembly 2 to have a certain support span in the horizontal direction. This effectively distributes the weight of the gimbal plate 31 and its load, reducing the risk of structural deformation or damage caused by excessive local stress. Furthermore, the connection between the two sets of scissor lift modules 21 via multiple connecting rods 22 further enhances the connection strength between components and the stability of the overall structure. When the gimbal plate 31 is subjected to external force, the force can be evenly distributed across the connecting rods 22 and the scissor lift modules 21, avoiding local stress concentration and thus ensuring the smoothness and reliability of the lifting process.

[0049] In this embodiment, the lifting drive component 23 is a hydraulic jack and is connected to the chassis 1 by a threaded connection. Due to the various failures that may occur in the lifting drive component 23 after long-term use, a bolted connection is used to facilitate timely replacement of the lifting drive component 23. Thus, when only the lifting drive component 23 fails, only the lifting drive component 23 can be replaced, which is less costly than replacing the entire lifting load-bearing device. Furthermore, as work requirements change, different models and specifications of the lifting drive component 23 can be replaced to meet the needs of different work scenarios.

[0050] In this embodiment, the lifting assembly 2 also includes a variety of connecting sleeves of different specifications. The connecting sleeves are fitted onto the output end of the lifting drive component 23 and connected to the adjacent connecting rod 22. By connecting the lifting drive component 23 and the adjacent connecting rod 22 through the connecting sleeves, the telescopic length can be adjusted by replacing the connecting sleeves of different lengths, thereby adjusting the lifting height, expanding the application range of the lifting load-bearing device and adapting to more working scenarios.

[0051] Optionally, such as Figure 2 As shown, the scissor lift module 21 includes a first scissor lift arm 211 and a second scissor lift arm 212 hinged at the midpoint. The first scissor lift arm 211 is located outside the second scissor lift arm 212. The end of the first scissor lift arm 211 near the chassis 1 is slidably connected to the chassis 1 along the second direction. The end of the first scissor lift arm 211 near the gimbal plate 31 is hinged to the gimbal plate 31. The end of the second scissor lift arm 212 near the chassis 1 is hinged to the chassis 1. The end of the second scissor lift arm 212 near the gimbal plate 31 is slidably connected to the gimbal plate 31 along the second direction. The connecting rod 22, which is connected to the lifting drive component 23, is connected to the first scissor lift arm 211.

[0052] By slidably connecting the end of the first scissor arm 211 near the chassis 1 to the chassis 1 along the second direction, and hinged the end of the first scissor arm 211 near the gimbal plate 31 to the gimbal plate 31, and hinged the end of the second scissor arm 212 near the chassis 1 to the chassis 1, and slidably connecting the end of the second scissor arm 212 near the gimbal plate 31 to the gimbal plate 31 along the second direction, and connecting the connecting rod 22 connected to the lifting drive 23 to the first scissor arm 211, the lifting drive 23 controls the first scissor arm 211 and the second scissor arm 212 to move closer to or further away from each other when the first scissor arm 211 and the second scissor arm 212 move further away from each other, the gimbal plate 31 descends, and the gimbal plate 31 rises when the first scissor arm 211 and the second scissor arm 212 move closer to each other.

[0053] In this embodiment, both the first scissor arm 211 and the second scissor arm 212 are provided with pin limiting holes 213. A horizontal limiting rod can be inserted into the pin limiting hole 213 to mechanically lock the first scissor arm 211 and the second scissor arm 212 in the vertical direction. This ensures that the goods will not slip due to the first scissor arm 211 and the second scissor arm 212 during transportation, which would cause the gimbal plate 31 to fall unexpectedly and the backpack air conditioner to slip off. This ensures the safety of the operator and the integrity of the goods.

[0054] Optionally, such as Figure 2As shown, the scissor lift module 21 includes a first guide rail 24, a second guide rail 25, a first roller 26, and a second roller 27. The first guide rail 24 corresponds one-to-one with the first scissor lift arm 211 and is connected to the chassis 1. The second guide rail 25 corresponds one-to-one with the second scissor lift arm 212 and is connected to the gimbal plate 31. The first roller 26 is connected to the end of the first scissor lift arm 211 near the chassis 1 and is rotatably disposed within the first guide rail 24. The second roller 27 is connected to the end of the second scissor lift arm 212 near the gimbal plate 31 and is rotatably disposed within the second guide rail 25.

[0055] By setting first guide rails 24 on the chassis 1 corresponding one-to-one with the first scissor arms 211, the first guide rails 24 limit and guide the sliding of the first scissor arms 211, ensuring the straightness of the sliding trajectory of the first scissor arms 211. By setting second guide rails 25 on the gimbal plate 31 corresponding one-to-one with the second scissor arms 212, the second guide rails 25 limit and guide the sliding of the second scissor arms 212, ensuring the straightness of the sliding trajectory of the second scissor arms 212. Furthermore, by setting first rollers 26 connected to the first scissor arms 211 in the first guide rails 24 and second rollers 27 connected to the second scissor arms 212 in the second guide rails 25, it is ensured that the sliding of the first scissor arms 211 in the first guide rails 24 and the sliding of the second scissor arms 212 in the second guide rails 25 are both rolling friction, thereby reducing the friction force during sliding and ensuring the smoothness of movement during lifting.

[0056] In this embodiment, the first guide rail 24 and the second guide rail 25 have the same structure, both including a guide rail base plate, a guide rail side plate and a guide rail limiting plate. The guide rail side plate is connected to both sides of the guide rail base plate along the first direction, and the guide rail limiting plate is connected to the side of the guide rail side plate away from the guide rail base plate, thereby forming a cavity for sliding. The guide rail base plate and the guide rail limiting plate are located on both sides of the first roller 26 and the second roller 27 along the axial direction, respectively, to limit the first roller 26 and the second roller 27 and prevent the first roller 26 and the second roller 27 from coming out of the cavity for sliding.

[0057] Optionally, such as Figure 2 , Figure 3 As shown, the gimbal assembly 3 includes gimbal side plates 38. Gimbal plate 31 has gimbal side plates 38 connected to both sides along a third direction. A first mounting groove is formed on the opposite side of each of the two gimbal side plates 38, and a second guide rail 25 is connected within the first mounting groove. By providing gimbal side plates 38 on the gimbal plate 31 and forming the first mounting groove on the gimbal side plates 38, the second guide rail 25 connected within the first mounting groove is provided with support and protection.

[0058] Optionally, such as Figure 3As shown, the gimbal assembly 3 also includes a tool box 39, which is connected to the gimbal plate 31 and located on the side of the first adjustment plate 33 opposite to the fixed plate 32. By setting the tool box 39 on the gimbal plate 31, the area enclosed by the tool box 39, the fixed plate 32, the first adjustment plate 33, and the second adjustment plate 34 is separated, making it convenient to classify and place equipment and tools. Workers can quickly find the required items, and they are less likely to be dropped or lost during transportation or use. It is also convenient to check the equipment and tools before and after work.

[0059] In this embodiment, a transfer device is also provided, which includes a chassis 1 and the aforementioned lifting and bearing device. The chassis 1 includes a first mounting base plate 11, a second mounting base plate 12, and two mounting side plates 13 arranged opposite each other along a third direction. One end of each mounting side plate 13 is connected to the first mounting base plate 11, and the other end is connected to the second mounting base plate 12. The lifting assembly 2 is connected to the two mounting side plates 13. By applying the aforementioned lifting and bearing device, this transfer device not only has the function of transfer and conveying but also has the ability to assist in disassembly and assembly operations.

[0060] In this embodiment, a second mounting groove is provided on one side of each of the two mounting side plates 13 facing each other, and the first guide rail 24 is connected to the second mounting groove. By providing a second mounting groove on the mounting side plate 13, the first guide rail 24 connected to the second mounting groove is provided with support and protection.

[0061] Optionally, such as Figure 1 As shown, the chassis 1 also includes a pair of fixed wheel sets 14 and a pair of omnidirectional wheel sets 15. The fixed wheel sets 14 are connected to the first mounting base plate 11 and have a locking mechanism. The omnidirectional wheel sets 15 are connected to the second mounting base plate 12 and have a disc brake mechanism.

[0062] By installing a fixed wheel assembly 14 with a locking mechanism on the first mounting base plate 11, the lifting load-bearing device can maintain straight-line travel during forward movement, effectively stabilizing its orientation and preventing it from veering off course. A swivel wheel assembly 15 with a disc brake mechanism is installed on the second mounting base plate 12, making steering more flexible and stable, suitable for operation in confined spaces or complex environments. Furthermore, the disc brakes provide strong braking force, stopping the rear wheels in a short time and allowing the lifting load-bearing device to brake quickly. When emergency stops are required or operations are needed on slopes or other special terrains, this effectively prevents the lifting load-bearing device from sliding or becoming uncontrollable, ensuring the safety of personnel and goods.

[0063] In this embodiment, as Figure 1 As shown, the chassis 1 also includes a push handle 16, which is connected to the second mounting base plate 12 to allow the operator to move the lifting and carrying device.

[0064] The working process of the transfer equipment with a lifting and carrying device is as follows: In the initial state, the gimbal plate 31 is in a low position. When it is necessary to disassemble the backpack air conditioner, the operator first uses the pusher 16 to move the lifting and carrying device to the working position, and then activates the hydraulic jack, which acts as the lifting drive component 23. At this time, the lifting drive component 23 will push the connecting rod 22 connected to it to extend. At this time, the first scissor arms 211 connected to the connecting rod 22 along the third direction will move towards the second scissor arms 212, so that the first scissor arms 211 and the second scissor arms 212 move closer to each other, thereby raising the gimbal plate 31. When the gimbal plate 31 abuts against the bottom surface of the backpack air conditioner, the lifting drive component 23 is closed, and a horizontal limiting rod is inserted into the pin limiting hole 213 on the first scissor arms 211 and the second scissor arms 212 for mechanical locking in the vertical direction. After the disassembly of the backpack air conditioner is completed, according to... To adjust the size of the backpack air conditioner, turn the first connecting piece 36 to adjust the position of the first adjusting plate 33, and turn the second connecting plate to adjust the position of the second adjusting plate 34. After the backpack air conditioner is fixed between the first adjusting plate 33, the second adjusting plate 34, and the fixed plate 32, turn the first connecting piece 36 and the second connecting piece 37 in the opposite direction to lock the first adjusting plate 33 and the second adjusting plate 34 with the gimbal plate 31.
