When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0033] In the field of industrial automation and logistics transportation, conveyor tracks are a key component for achieving component transportation. In the actual production process, R&D personnel found that most traditional conveyor tracks can only transport components in a straight line and cannot change the direction of component transportation; when faced with complex path transportation, they cannot meet the diverse needs of industrial automation and material transportation.

[0034] The present invention provides a lifting device and a lift, aiming to solve the technical problem that a conveying track cannot change the conveying direction of a component.

[0035] See also Figure 1 and Figure 2 In one embodiment of the present invention, the lifting device includes a base 100, a first conveying mechanism 200, a second conveying mechanism 300 and a lifting mechanism 400. The base 100 is provided with a mounting rod 110. The first conveying mechanism 200 is slidably arranged on the mounting rod 110 along the height direction of the base 100 and can convey components along a first direction. The first conveying mechanism 200 is provided with a first conveying surface; the second conveying mechanism 300 is arranged on the base 100 and can convey components along a second direction. The second conveying mechanism 300 is provided with a second conveying surface. The lifting mechanism 400 is arranged on the first conveying mechanism Below the first conveying mechanism 200, the lifting mechanism 400 includes a connecting frame 410 hinged to the mounting rod 110, a connecting rod 420 hinged to the connecting frame 410, a swing arm 430 hinged to the connecting rod 420, and a driving motor 440 arranged on the base 100. The connecting frame 410 is provided with a protrusion 411, and the protrusion 411 abuts against the first conveying mechanism 200; the driving motor 440 can drive the connecting frame 410 to rotate through the swing arm 430 and the connecting rod 420, thereby driving the first conveying mechanism 200 to slide along the height direction of the base 100, and make the first conveying surface higher or lower than the second conveying surface. Among them, the first direction refers to Figure 1 The second direction is the direction indicated by X in Figure 1 In the direction indicated by Y in FIG. 1 , in a specific embodiment, the first direction may be one of the width direction and the length direction of the base 100 , and the second direction may be the other of the width direction and the length direction of the base 100 .

[0036] The technical solution of the present invention can change the conveying direction of the component by setting a first conveying mechanism 200 for conveying the component along the first direction, a second conveying mechanism 300 for conveying the component along the second direction, and a lifting mechanism 400 for driving the first conveying mechanism 200 to rise and fall; the lifting device is installed at the corner of the conveying track, so that the conveying direction of the component can be changed to meet the diversified needs of industrial automation and material transportation. In this embodiment, the first conveying mechanism 200 can convey the component along the first direction, and the second conveying mechanism 300 can convey the component along the second direction. The lifting mechanism 400 drives the first conveying mechanism 200 to rise and fall, so that the first conveying surface is higher or lower than the second conveying surface, and the components can be supported by different conveying mechanisms to change the conveying direction of the component. Specifically, when conveying the component, the second conveying mechanism 300 first conveys the component to the base 100 along the second direction, and then the lifting mechanism 400 drives the first conveying mechanism 200 to rise until the first conveying mechanism 200 supports the component, and finally the first conveying mechanism 200 sends the component away from the base 100 along the first direction, so that the conveying direction of the component can be changed. At the same time, the lifting device uses a driving motor 440 and a cam structure to drive the first conveying mechanism 200 to rise and fall. The driving motor 440 can efficiently convert electrical energy into mechanical energy to reduce energy loss and waste; and the mechanical structures such as the connecting rod 420 and the connecting frame 410 are used to realize the transmission of motion, which can reduce energy loss and improve transmission efficiency. The lifting device is applied to the field of conveying equipment technology.

[0037] It should be noted that the process of the lifting device changing the conveying direction of the component can also be: first, the first conveying mechanism 200 conveys the component to the base 100 along the first direction, then the lifting mechanism 400 drives the first conveying mechanism 200 to descend until the second conveying mechanism 300 supports the component, and finally the second conveying mechanism 300 conveys the component away from the base 100 along the second direction. In this embodiment, in order to prevent the component from sliding off the base 100, a limit block can be set on one side of the first conveying mechanism 200 and the second conveying mechanism 300 to limit the position of the component when the first conveying mechanism 200 or the second conveying mechanism 300 conveys the component to the base 100, thereby reducing the risk of the component sliding off.

[0038] See also Figure 2In one embodiment of the present invention, there are two connecting frames 410, both of which are hinged to the mounting rod 110, and both ends of the connecting rod 420 are hinged to the two connecting frames 410. In this embodiment, the two connecting frames 410 are respectively arranged corresponding to the two ends of the first conveying mechanism 200. When the driving motor 440 drives the connecting frames 410 to rotate, the two connecting frames 410 will rotate at the same time, thereby driving the first conveying mechanism 200 to rise or fall. By driving the first conveying mechanism 200 to rise and fall through the two connecting frames 410, the stability of the first conveying mechanism 200 during lifting and lowering can be improved.

[0039] See also Figure 2 and Figure 3 In one embodiment of the present invention, the protrusion 411 is provided with a roller 412, and the first conveying mechanism 200 is provided with a fixing plate at a position corresponding to the roller 412, and the roller 412 abuts against the fixing plate. In this embodiment, by providing the roller 412 on the protrusion 411, the roller 412 abuts against the fixing plate of the first conveying mechanism 200, which can reduce the friction when the lifting mechanism 400 drives the first conveying mechanism 200 to rise and fall, thereby improving the transmission efficiency.

[0040] In one embodiment of the present invention, the swing arm 430 is provided with a driving shaft 431, the driving shaft 431 is provided with a first gear 432, and the output end of the driving motor 440 is provided with a second gear 441, and the second gear 441 is meshed with the first gear 432. In this embodiment, the driving motor 440 is driven by gear meshing to drive the first conveying mechanism 200 to rise and fall, which can improve the stability of the first conveying mechanism 200 when it is raised and lowered.

[0041] In one embodiment of the present invention, there are two drive motors 440, which are arranged on both sides of the drive shaft 431, and the output ends of the two drive motors 440 are both provided with second gears 441, and one of the two second gears 441 is meshed with the first gear 432. The two drive motors 440 are defined as the first drive motor 440 and the second drive motor 440; specifically, in normal operation, the second gear 441 of the first drive motor 440 is meshed with the first gear 432, at which time, the first drive motor 440 can drive the connecting frame 410 to rotate through the drive shaft 431, the swing arm 430, and the connecting rod 420, thereby driving the first conveying mechanism 200 to rise and fall; and when the first drive motor 440 fails, the external controller can control the second gear 441 of the second drive motor 440 to mesh with the first gear 432, at which time, the second drive motor 440 can drive the first conveying mechanism 200 to rise and fall. By providing two drive motors 440, when one of the drive motors 440 fails, the other drive motor 440 can be switched to in time to ensure the normal use of the lifting device. At the same time, it can also reduce the maintenance frequency and improve production efficiency.

[0042] In this embodiment, the number of the first conveying mechanism 200, the second conveying mechanism 300 and the lifting mechanism 400 are all two, the two first conveying mechanisms 200 are arranged at intervals on the mounting rod 110 along the second direction, the two second conveying mechanisms 300 are arranged at intervals on the base 100 along the first direction, and the two lifting mechanisms 400 are respectively arranged directly below the two first conveying mechanisms 200. Providing two first conveying mechanisms 200 and second conveying mechanisms 300 can provide more stable conveying components. The swing arms 430 of the two lifting mechanisms 400 are connected to the two ends of the same driving shaft 431.

The first conveying mechanism 200 is provided with a slide bar 210 extending along the height direction of the machine base 100, and the two sides of the slide bar 210 are respectively slidably connected with the two guide wheels 112. In this embodiment, the guide wheels 112 are arranged on the slide 111 at intervals along the first direction; the slide bar 210 is placed between the two guide wheels 112, which can provide guidance for the lifting and lowering of the first conveying mechanism 200, so as to improve the stability of the first conveying mechanism 200 when lifting and lowering.

[0044] In one embodiment of the present invention, the slide 111 is further provided with a limiting wheel 113, and the limiting wheel 113 abuts against the side of the slide bar 210 away from the first conveying mechanism 200. In this embodiment, the limiting wheel 113 can abut against the side of the slide bar 210 away from the first conveying mechanism 200 to limit the position of the slide bar 210, thereby preventing the slide bar 210 from contacting the slide 111, reducing wear, and improving the service life of the lifting device.

In other words, only one first driving member 230 is required to drive all the first conveying wheels 240 to rotate, which can reduce the production cost.
