Abstract
Description
Technical Field
[0001] The embodiments of this utility model relate to the field of transmission mechanism technology, specifically to a vertical circulating transmission device. Background Technology
[0002] In today's era of rapid industrial development, various types of machinery and equipment are widely used in various fields to meet the ever-increasing demands of production and daily life. As an important mechanical component, the cyclic transmission device enables the continuous cyclical motion of objects, providing strong support for the automation and efficiency of production processes. It is widely used in material handling, production assembly lines, and warehousing equipment, among many other areas.
[0003] Taking multi-level parking garages as an example, with the acceleration of urbanization and the increasing scarcity of urban land resources, multi-level parking garages have become an important means of solving urban parking problems because they can save land area and increase parking capacity. In the operation of a multi-level parking garage, a circulating transmission device drives a vertically arranged chain, which in turn drives the parking space brackets installed on the chain to move up and down, thereby realizing the three-dimensional storage and retrieval of vehicles.
[0004] However, most existing automated parking systems use a design where the sprocket is coaxially mounted on the drive shaft, directly driving the sprocket. Because the drive shaft and sprocket are coaxial, their maintenance and repair interfere with each other. When maintenance of the drive shaft is required, it is difficult to perform separate maintenance without disassembling the sprocket and chain, as the sprocket is connected to the drive shaft and the chain is wrapped around it. This undoubtedly increases the difficulty and workload of maintenance, prolongs equipment downtime, and reduces the efficiency of the automated parking system.
[0005] In conclusion, optimizing the convenience of maintenance and repair of the transmission mechanism of automated parking systems has become an important technical problem that urgently needs to be solved. Utility Model Content
[0006] To overcome the above-mentioned defects, the embodiments of this utility model provide a vertical circulating transmission device, which solves the technical problem in the related technology where the main drive shaft and sprocket are coaxially set, and their maintenance and repair affect each other, making it difficult to perform separate maintenance on the drive shaft without disassembling the sprocket and chain.
[0007] According to one aspect, at least one embodiment of the present invention provides a vertical circulating transmission device, including a support, a circulating transmission component, a rotary drive component, an internal gear ring, and a drive gear. The circulating transmission component is circumferentially arranged relative to the support, and the rotary drive component is rotatably arranged relative to the support. The circulating transmission component is sleeved on the rotary drive component, and the rotary drive component is used to drive the circulating transmission component to circulate. The internal gear ring is coaxially arranged on the rotary drive component, and the drive gear is rotatably arranged relative to the support. The drive gear meshes with the internal gear ring and is used to drive the rotary drive component to rotate.
[0008] For example, in at least one embodiment of the present invention, a vertical circulating transmission device further includes:
[0009] The circulating transmission component is a circulating chain, on which rollers are rotatably mounted. There are multiple rollers evenly distributed. The rotary drive component is a rotating dial, which has multiple slots arranged circumferentially. The slots are configured to engage with the multiple rollers on the circulating chain one by one under the drive of the rotating dial, so as to drive the circulating chain to move.
[0010] For example, in at least one embodiment of the present invention, a vertical circulating transmission device further includes:
[0011] It also includes a three-stage transmission structure, which includes a drive motor, a secondary transmission shaft, and a tertiary transmission shaft. The drive motor is mounted on the support, and both the secondary and tertiary transmission shafts are rotatably mounted on the support. The output shaft of the drive motor is drivenly connected to the secondary transmission shaft, and the secondary transmission shaft is drivenly connected to the tertiary transmission shaft. The drive gear is coaxially mounted on the tertiary transmission shaft.

[0022] The beneficial effects of the embodiments of this utility model are as follows:
[0023] In this invention, the main drive shaft and the rotary drive component are designed as separate structures by adding a drive gear and an internal gear ring. During maintenance and repair, the main drive shaft component can be disassembled separately.

[0029] 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 its scope.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components.

Therefore, they should not be construed as limitations on this utility model.
[0034] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0035] like Figures 1-3 As shown, this invention illustrates a vertical circulating transmission device according to one embodiment, comprising a support 1, a circulating transmission component 2, a rotary drive component 3, an internal gear ring 4, and a drive gear 5. The support 1 is the basic support structure of the entire vertical circulating transmission device. The circulating transmission component 2 can be a chain or a drive belt, but a chain is generally used when used in a multi-level parking garage. The rotary drive component 3 can be a sprocket or a pulley, but a sprocket is generally used when used in a multi-level parking garage. The circulating transmission component 2 surrounds the rotary drive component 3, forming a circulating loop. The parking space bracket is mounted on the chain and rises and falls with the cyclical movement of the chain. The internal gear ring 4 is coaxially arranged with the rotary drive component 3. The drive gear 5 is rotatably arranged relative to the support 1 and is used to connect to the main drive shaft, transmitting the power of the main drive shaft to the drive gear 5, thereby driving the rotary drive component 3 to rotate.
[0036] When the automated parking system is in operation, the main drive shaft drives the drive gear 5 to rotate. Since the drive gear 5 meshes with the internal gear ring 4, the rotation of the drive gear 5 causes the internal gear ring 4 to rotate. Because the internal gear ring 4 is coaxially mounted with the rotary drive component 3, it drives the rotary drive component 3 to rotate as well, thereby causing the circulating transmission component 2 mounted on it to perform a cyclical motion. The parking space brackets mounted on the circulating transmission component 2 move vertically up and down with the cyclical motion, thus completing the three-dimensional storage and retrieval operation of vehicles.
[0037] By adding a drive gear 5 and an internal gear ring 4, the main drive shaft and the rotary drive component 3 are designed as separate structures. During maintenance and repair, the main drive shaft assembly can be disassembled separately. Because the drive gear 5 can easily disengage from the internal gear ring 4, it is not necessary to disassemble the rotary drive component 3 and the circulating transmission component 2, reducing maintenance difficulty and workload, shortening equipment downtime, and improving the efficiency of the automated parking system. This separate transmission structure design is versatile and can be applied not only to automated parking systems but also to other industrial equipment requiring circulating transmission.
[0038] In addition, by coaxially setting an internal gear ring 4 on the rotary drive 3, compared with setting it as an external gear ring, the design of the internal gear ring 4 allows the drive gear 5 to be placed in the inner ring space of the internal gear ring 4 and drive the rotary drive 3, which can further reduce the space occupied in the vertical direction.
[0039] In some examples, such as Figures 1-3 As shown, the circulating chain serves as the circulating transmission component 2, and multiple rollers 6 are rotatably mounted on the circulating chain, with these rollers 6 evenly distributed on the chain. A conventional slewing bearing 10 is mounted on the support 1, with the outer ring of the slewing bearing 10 fixedly mounted on the support 1. The slewing drive component 3 is coaxially mounted on the inner ring of the slewing bearing 10. The slewing drive component 3 is preferably a rotating dial, with multiple grooves 7 evenly arranged circumferentially on the rotating dial. The shape and size of the grooves 7 match the rollers 6. When the rotating dial rotates, the grooves 7 can mesh with the rollers 6 and drive the rollers 6, thereby driving the circulating chain to move.
[0040] When the vertical circulation transmission device is working, the drive gear 5 drives the internal gear ring 4 to rotate, which in turn causes the rotating dial, which is coaxial with the internal gear ring 4, to rotate. The grooves 7 on the rotating dial mesh one-to-one with the rollers 6 on the circulation chain, thereby driving the circulation chain to perform cyclical motion. Compared with the traditional sprocket and chain structure, in this solution, even if friction occurs between the grooves 7 and the rollers 6, the contact between the rollers 6 and the grooves 7 is rolling friction, which greatly reduces friction compared to the hard friction between the traditional sprocket and chain. This reduces energy loss and noise generation, while extending the service life of the circulation chain and the rotating dial.
[0041] In some examples, such as Figure 2 As shown, the drive motor 801 is mounted on the support 1, serving as the power source for the transmission system and providing power to the vertical circulating transmission device. A primary sprocket 8011 is coaxially mounted on the output shaft of the drive motor 801. The secondary transmission shaft 802 is rotatably mounted on the support 1, and a secondary input sprocket 8021 and a secondary output sprocket 8022 are coaxially mounted on the secondary transmission shaft 802. The tertiary transmission shaft 803 is rotatably mounted on the support 1, and a tertiary sprocket 8031 and a drive gear 5 are coaxially mounted on the tertiary transmission shaft 803. In the three-stage transmission structure 8, a primary chain 8012 is sleeved between the primary sprocket 8011 and the secondary input sprocket 8021, and a secondary chain 8023 is sleeved between the secondary output sprocket 8022 and the tertiary sprocket 8031.
[0042] When the vertical circulating transmission device is started, the drive motor 801 begins to run, and its output shaft drives the first-stage sprocket 8011 to rotate. The first-stage sprocket 8011 transmits power to the second-stage input sprocket 8021 on the second-stage transmission shaft 802 through the first-stage chain 8012, causing the second-stage transmission shaft 802 to rotate. As the second-stage transmission shaft 802 rotates, its second-stage output sprocket 8022 also rotates synchronously. The second-stage output sprocket 8022 then transmits power to the third-stage sprocket 8031 on the third-stage transmission shaft 803 through the second-stage chain 8023, thereby driving the third-stage transmission shaft 803 to rotate. Since the drive gear 5 is coaxially mounted on the third-stage transmission shaft 803, the rotation of the third-stage transmission shaft 803 drives the drive gear 5 to rotate. The drive gear 5 meshes with the internal gear ring 4, thereby driving the rotary drive component 3 to rotate, ultimately realizing the cyclic movement of the circulating transmission component 2, driving the parking space bracket to rise and fall.
[0043] The transmission mechanism is designed as a three-stage system, with each stage acting as a buffer and stabilizing force. This reduces the impact and vibration caused by direct drive, making the entire transmission process more stable and the lifting and lowering of the parking space bracket smoother. It also reduces noise during operation.
[0044] In some examples, such as Figure 1 As shown, two sets of circulating chains and three-stage transmission structures 8 are symmetrically arranged, with the two sets of circulating chains and three-stage transmission structures 8 located on both sides of the device. In practical applications, such as in multi-level parking garages, the symmetrical structure can more evenly distribute the weight of the components to be lifted (such as parking space brackets and vehicles), avoiding structural deformation or instability caused by uneven force distribution.
[0045] Two sets of secondary drive shafts 802 are connected by a secondary universal coupling 8024, and two sets of tertiary drive shafts 803 are connected by a tertiary universal coupling 8032. The function of the universal couplings is to achieve synchronous transmission between the two sets of secondary drive shafts 802 and the two sets of tertiary drive shafts 803. Taking the secondary universal coupling 8024 as an example, it is installed at the corresponding ends of the two sets of secondary drive shafts 802, enabling the two sets of secondary drive shafts 802 to effectively transmit torque. During operation, even if the two sets of secondary drive shafts 802 experience slight angular deviations due to installation errors, operating vibrations, or other factors, the secondary universal coupling 8024 can still ensure the synchronous operation of the two sets of circulating chains. The tertiary universal coupling 8032 serves the same function between the two sets of tertiary drive shafts 803.
[0046] Both sets of circulating chains are equipped with mounting plates 9, which are used to mount the components to be lifted, such as parking space brackets. The surface of the mounting plates 9 is designed with mounting holes that match the parking space brackets. The presence of mounting plates 9 on both sets of circulating chains ensures that the components to be lifted receive more balanced support during the lifting process, further improving the stability of the lifting process.
[0047] The circulating chains are arranged vertically, which effectively utilizes vertical space. For example, in a multi-level parking garage, vehicles need to be parked at different vertical levels. The vertically arranged circulating chains can directly lift the parking space brackets to the corresponding height to meet the parking needs. At the same time, this arrangement saves lateral space, making the overall layout of the multi-level parking garage more compact and allowing for more parking spaces to be set up in a limited area.
