Description

TECHNICAL FIELD

[0001] The utility model belongs to the vertical lift technical field, concretely relates to a vertical lift. BACKGROUND

[0002] The vertical lift is a hoisting mechanical equipment for conveying personnel or various cargos in the vertical direction, and is especially suitable for vertical conveying requirements in the logistics system of factories, warehouses and the like. This kind of equipment greatly improves work efficiency and effectively shortens work cycle by virtue of accurate lifting and conveying capacity, and is an important tool indispensable in the modern logistics system.

[0003] Most of the conventional vertical lifts are screw rod driving mechanisms, i.e., screw rod vertical lifts, which realize vertical lifting through screw rod transmission systems, and are widely used in various vertical conveying scenarios due to stability, safety and reliability and the like. However, in actual application, especially when matched with production lines, the functional requirements of the vertical lift are often more complex, and in order to meet these requirements, the lifting platform often needs to be adaptively designed. Commonly, in order to smoothly convey products to the next process, a translation assembly is usually added to the lifting platform so as to smoothly translate the products from the equipment main body to the next process. This design, although enhancing the convenience of the equipment, will also encounter many problems, because of the various sizes of products and the customization of the lifting platform, the adaptability of the lifting platform and the products is often affected, resulting in the need for different models of lifting machines for different sizes of products, which not only increases the cost of the equipment, but also may cause the production efficiency to decrease. Although the screw rod transmission system has many advantages, because it depends on the rotation of the screw pair to convert into linear motion, the lifting speed is relatively slow, and in the occasion where material handling or production line docking needs to be quickly and efficiently completed, the relatively slow lifting speed of the screw rod transmission system may become a key factor restricting the production efficiency.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0028] Reference Figures 1-6 The utility model provides a vertical lift, including lift frame 1 and lifting mechanism, the inside bottom of lift frame 1 is equipped with vertical lifting frame 2, the lifting mechanism includes lifting platform 3 and drive assembly, lifting platform 3 is installed on vertical lifting frame 2 and slides, drive assembly is installed in lift frame 1, and lifting platform 3 can be driven to lift along vertical lifting frame 2, lifting platform 3 is equipped with belt conveying assembly, and the mobile end of belt conveying assembly is fixedly connected with moving platform 4, moving platform 4 is equipped with clamping assembly, and clamping assembly includes matched fixing block 5 and clamping block 6, fixing block 5 is connected on moving platform 4, and clamping block 6 is elastically connected with moving platform 4.

[0029] The vertical lift has wide application potential in factory, warehouse and other logistics systems, can flexibly cope with the vertical conveying demand of different size products on the same production line or conveying line, and smoothly connects the products to the next process, significantly improves the practicability and convenience of the equipment. Specifically, the working principle is as follows:

[0030] Firstly, on the moving platform 4, the clamping assembly plays a role in fixing the product, by moderately extruding the clamping block 6, using the elastic gap between the clamping block 6 and the fixed block 5, easily accommodating and fixing products of different sizes. Once the product is placed in place, the clamping block 6 will press the product tightly on the fixed block 5 under the action of elastic restoring force, ensuring the stability of the product during movement. Subsequently, the drive assembly is started, driving the lifting platform 3 to lift along the vertical lifting frame 2 until the lifting platform 3 reaches the required height for the next process. When the lifting platform 3 reaches the required height, the belt conveying assembly is started, driving the moving platform 4 on it to move outward, thereby moving the product out of the device interior, thereby facilitating the next process. Compared with the traditional elevator, the vertical elevator can effectively fix products of different sizes on the moving platform 4 through the clamping assembly, effectively meeting the vertical conveying needs of products of different sizes, making it widely applicable in various application scenarios. Avoiding the complexity of having to equip multiple elevators due to the diversification of product sizes, effectively reducing equipment costs, and simplifying production processes, without the need for classification processing of products of different sizes, thereby effectively improving production efficiency. It is worth mentioning that the number of lifting platforms 3 can be increased, arranged according to production needs.

[0031] In a specific embodiment, referring to Figures 2-4 , the belt conveying assembly includes two mounting plates 7, two transmission shafts 8, two belt pulleys 9, a conveying belt 10, a servo motor 11 and a drive belt 12. The two mounting plates 7 are connected in parallel on both sides of the lifting platform 3. The two transmission shafts 8 are rotatably connected to the mounting plates 7 at both ends. Two belt pulleys 9 are arranged on each transmission shaft 8. The belt pulleys 9 on the same side of the two transmission shafts 8 are connected by the conveying belt 10. The top surface of the conveying belt 10 is connected to the moving platform 4 by a connecting block 13. The servo motor 11 is installed below the mounting plate 7 by a connecting plate and is connected to the transmission shaft 8 by a drive belt 12.

[0032] The belt conveying assembly realizes the movement of the moving platform 4 along the path of the conveying belt 10 through the cooperation of the mounting plates 7, the transmission shafts 8, the pulleys 9, the conveying belt 10, the servo motor 11 and the driving belts 12, thereby ensuring the quick connection of products between different processes and improving the production efficiency. Specifically, the servo motor 11 transmits power to the transmission shafts 8 through the driving belts 12, and as the transmission shafts 8 rotate, the pulleys 9 on them also rotate and cooperate with the corresponding pulleys 9 on the other transmission shafts 8 to jointly drive the conveying belt 10 to move stably. The conveying belt 10 is connected to the moving platform 4 through the connecting block 13, ensuring that the moving platform 4 can move along the movement path of the conveying belt 10, thereby realizing the circulation of products between different processes.

[0033] In a specific embodiment, referring to Figure 5 The mounting plates 7 are provided with angle steels 14 on the side close to the conveying belt 10, and the top surface of the angle steel 14 is arranged on the bottom surface of the upper conveying belt 10.

[0034] Since the carrying capacity of the conveying belt 10 is limited, in order to further improve its carrying capacity and stability, the vertical elevator adopts the design of arranging the angle steel 14 on the bottom surface of the upper conveying belt 10 to effectively support the conveying belt 10. This design ensures that the conveying belt 10 can maintain good tension and stability even when carrying heavy products, effectively preventing the risk of belt relaxation or damage due to excessive load, making the conveying process more stable and reliable and ensuring production efficiency.

[0035] In a specific embodiment, referring to Figure 4 Further comprising a limiting plate 15, the two ends of the limiting plate 15 are respectively vertically installed on the mounting plates 7 on both sides, and the limiting plate 15 is located behind the moving platform 4 and can limit the backward movement of the moving platform 4.

[0036] The limiting plate 15 is connected with the mounting plates 7 on both sides, which not only improves the overall structural stability of the belt conveying assembly, but also limits the further backward movement of the moving platform 4, effectively limiting the movement range of the moving platform 4 and ensuring the smooth and safe operation of the equipment.

[0037] In a specific embodiment, referring to Figure 3 and Figure 6 The moving platform 4 is provided with a sliding seat 16, the tail part of the clamping block 6 is provided with a shaft rod 17, the shaft rod 17 penetrates through the sliding seat 16 and is movably connected with the sliding seat 16, a spring 18 is sleeved between the shaft rod 17 and the clamping block 6, and the tail end of the shaft rod 17 is provided with a baffle 19.

[0038] The clamping block 6 is movably connected with the sliding seat 16 through the shaft 17 at the tail end, and the spring 18 sleeved on the shaft 17 provides the clamping block 6 with continuous and adjustable clamping force. This design enables the clamping block 6 to be adaptively adjusted according to the size of the product, thereby not only improving the flexibility of clamping, but also ensuring that products of different sizes can be stably clamped, effectively avoiding the shaking or falling of the products during the conveying process. In addition, the tail end of the shaft 17 is provided with a baffle 19 to prevent accidental falling of the shaft 17 during use, thereby enhancing the safety and stability of the entire clamping assembly.

[0039] In a specific embodiment, referring to Figures 2-4 , the driving assembly includes a hydraulic oil cylinder 20, a first pulley 21, a second pulley 22, and a transmission belt 23. The hydraulic oil cylinder 20 is installed at the inner bottom of the elevator frame 1 and located at the opposite side of the lifting platform 3. The top surface of the vertical lifting frame 2 is provided with a top plate 24. The first pulley 21 is installed at the telescopic end of the hydraulic oil cylinder 20. The second pulley 22 is installed on the top surface of the top plate 24. One end of the transmission belt 23 is fixedly connected to the bottom surface of the top plate 24, and the other end is sequentially wound around the first pulley 21 and the second pulley 22 and connected above the lifting platform 3.

[0040] The vertical elevator utilizes the hydraulic cylinder 20 as a power source, one end of the transmission belt 23 is fixedly connected to the bottom surface of the top plate 24 of the elevator frame 1, the other end is sequentially wound around the first pulley 21 and the second pulley 22, and is finally connected above the lifting platform 3. The first pulley 21 and the second pulley 22 serve as support and guide points for the transmission belt 23, effectively reducing the friction and wear of the transmission belt 23 during transmission, thereby prolonging the service life of the transmission belt 23. The height difference between the first pulley 21 and the second pulley 22 directly affects the height of the lifting platform 3. When the height difference is greater, the length of the transmission belt 23 between the first pulley 21 and the second pulley 22 will increase accordingly, and the length of the transmission belt 23 connected to one end of the lifting platform 3 will shorten, thereby enabling the lifting platform 3 to reach a higher position. Specifically, when the hydraulic cylinder 20 is in elongation operation, the first pulley 21 rises, and the height difference between the first pulley 21 and the second pulley 22 decreases. At this time, through the cooperation of the pulley set, the transmission belt 23 at one end of the lifting platform 3 begins to elongate, and the lifting platform 3 slowly descends under the action of its own gravity. In this process, the transmission belt 23 always maintains a straightened state, ensuring the stability and accuracy of the descent of the lifting platform 3. Conversely, when the hydraulic cylinder 20 is in shortening operation, it can drive the lifting platform 3 to rise to the desired height. Compared with the traditional elevator driven by a lead screw transmission system, the lifting speed of the vertical elevator is effectively improved, which can meet the task of quickly and efficiently completing product handling or production line docking, thereby effectively improving production efficiency.

[0041] In a specific embodiment, referring to Figure 3 and Figure 4 , the vertical lifting frame 2 is provided with a sliding rail 25 on one side close to the lifting platform 3, the lifting platform 3 is provided with a support plate 29 on one side close to the vertical lifting frame 2, the support plate 29 is provided with a sliding block 26 that slidably cooperates with the sliding rail 25, and the transmission belt 23 is connected above the support plate 29.

[0042] The lifting platform 3 is slidably installed on the sliding rail 25 of the vertical lifting frame 2 through the sliding block 26 on the support plate 29, and the sliding rail 25 serves as a guide structure to ensure that the movement trajectory of the lifting platform 3 in the vertical direction always remains on the predetermined path, avoiding unnecessary shaking or deviation, and effectively improving the stability of the lifting operation.

[0043] In a specific embodiment, referring to Figure 2 and Figure 4 , the vertical lifting frame 2 is symmetrically provided with a hydraulic buffer rod 27 and a limiting rod 28 corresponding to the position of the support plate 29 on the upper and lower sides, and the length of the limiting rod 28 is shorter than that of the hydraulic buffer rod 27.

[0044] When the hydraulic buffer rod 27 is in contact with the supporting plate 29 when the lifting platform 3 is lifted to the highest position or lowered to the lowest position, the hydraulic buffer rod 27 plays a buffering role by using the hydraulic damping mechanism inside the hydraulic buffer rod 27, absorbs the impact energy of the lifting platform 3 at the limit position, and makes it stop smoothly at the predetermined position, and the limiting rod 28 can effectively avoid the potential risk that the lifting platform 3 slips out of the slide rail 25 due to mechanical failure or improper control.

[0045] The above is only an embodiment of the present application, and does not limit the patent range of the present application, and any equivalent structure or equivalent process transformation using the content of the present application specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection range of the present application.
