Technical Field
[0001] This utility model belongs to the field of material conveying technology, and specifically relates to a lifting device. Background Technology
[0002] Industries such as home appliances, 3C products, and automobile manufacturing have largely achieved automated production. The entire production line relies heavily on lifting devices, which enable the transport of products between floors. In existing technologies, for lighter lifting devices with faster cycle times, a continuous circulating structure is generally chosen; for heavier products with lower cycle times, a reciprocating vertical structure lifting device is typically selected.
[0003] When producing heavy products with a fast production cycle, it is necessary to increase the operating speed of the lifting device. However, when the operating speed of the lifting device exceeds 2m / s, the impact force of the lifting device is very large, which may lead to the risk of the lifting device overshooting the top.
[0004] To address the existing problems, we propose a lifting device.
[0005] The information disclosed in this background section is only for understanding the background technology of the present invention, and therefore may include information that does not constitute prior art. Utility Model Content

Detailed Implementation
[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Depend on Figure 1 As shown, a lifting device includes a support 1, a housing 2, a conveying mechanism, and a lifting mechanism 4, wherein:
[0030] The support 1 includes a accommodating space and a first doorway 11, a second doorway 12 and a third doorway 13 that communicate with the outside. The first doorway 11, the second doorway 12 and the third doorway 13 are all located on the same side of the compartment 2, and each of the first doorway 11, the second doorway 12 and the third doorway 13 is provided with an openable and closable sealed door.
[0031] Specifically, the interior of the accommodating space is equipped with anti-collision components.
[0032] The compartment 2 is located within the accommodating space. The compartment 2 includes an intermediate body 21. The two ends of the intermediate body 21 are respectively provided with a first compartment 22 and a second compartment 23. Both the first compartment 22 and the second compartment 23 are provided with openings.
[0033] The conveying mechanism includes a first conveyor body 31, a second conveyor body 32, and a third conveyor body 33. The first conveyor body 31 is located at the first doorway 11 and extends into the first doorway 11 to transport goods from the compartment 2. The second conveyor body 32 is located at the second doorway 12, with one end extending into the second doorway 12 to transport goods from the compartment 2, and the other end extending to the outside of the support 1 to transport and store goods. The second conveyor body 32 is equipped with a fence. The third conveyor body 33 is located at the third doorway 13, with one end extending into the third doorway 13 to transport goods from the compartment 2, and the other end extending to the outside of the support 1 to transport and store goods. The third conveyor body 33 is equipped with a fence, with an opening on one side of the fence.
[0034] Specifically, at least one of the first conveyor 31, the second conveyor 32, and the third conveyor 33 is a roller conveyor, a belt conveyor, or a chain conveyor.
[0035] Specifically, both the second conveyor 32 and the third conveyor 33 are partially located outside the accommodating space.
[0036] Specifically, after the items arrive at the third doorway 13, they are transported by the conveyor mechanism to the third conveyor body 33 outside the support 1. Because the fence has an opening, the items can be transported to the next work station from the opening.
[0037] The lifting mechanism 4 includes a motor and a chain to drive the box 2 to lift and lower. The motor is a variable frequency motor with a brake.
[0038] Specifically, the lifting mechanism 4 also includes a counterweight, which is connected and suspended in the compartment 2 by a wire rope or chain.
[0039] like Figure 2 and Figure 3 As shown, the compartment 2 includes a first state and a second state. In the first state, the opening of the first compartment 22 and the second doorway 12 are opposite to each other, and the opening of the second compartment 23 is opposite to the first doorway 11. In the second state, the opening of the first compartment 22 and the third doorway 13 are opposite to each other, and the opening of the second compartment 23 and the second doorway 12 are opposite to each other.
[0040] Working principle and usage process of this utility model:
[0041] When the compartment is at the bottom (at this time, the first compartment 22 and the second doorway 22 are opposite each other, the second compartment 23 and the third doorway 13 are opposite each other, and the bottom of the first compartment 22 and the bottom of the second compartment 23 are respectively located on the buffer layer plane 102 and the entrance layer plane 101), the items are then transported into the first compartment 22 through the first conveyor 31. The lifting device is then activated to raise the compartment to its highest position (at this time, the first compartment 22 and the third doorway 13 are opposite each other, the second compartment 23 and the second doorway 12 are opposite each other, and the bottom of the first compartment 22 and the bottom of the second compartment 23 are respectively located on the exit layer plane 103 and the buffer layer plane 102). The items are removed from the second compartment 23 and transported to the outside of the holding space via the second conveyor 32 (these items are for re-transportation). The lifting device is activated again to lower the compartment to its lowest position. The items to be transported are then transported to the second compartment 23 via the first conveyor 31, and the items for re-transportation are transported to the first compartment 22 via the second conveyor 32. The lifting device is activated to raise the compartment to its highest position. The items are removed from the first compartment 22 and the second compartment 23 respectively, and transported to the outside of the holding space via the third conveyor 33 and the second conveyor 32 respectively. This process is repeated until all the items to be transported are placed on the third conveyor 33. Because the fence of the third conveyor 33 has an opening, the items can be transported to the next workstation through this opening.
