Description

Technical Field

[0001] This utility model relates to the field of transmission component technology, specifically to a lifting and reversing integrated mechanism for a four-way shuttle. Background Technology

[0002] Four-way shuttles typically have a compact and agile body. Their shape usually resembles a small transport vehicle capable of moving along the tracks of a racking system. The vehicle is equipped with multiple drive wheels that allow it to move in different directions, hence the name "four-way"—it can move longitudinally, laterally, and diagonally (at 45-degree angles) within the racking system's track network.

[0003] In the prior art, for example, Chinese Patent Publication No. CN211970587U discloses a lifting and reversing integrated handling device, including: a main frame, a lifting frame, a first traveling drive device, a first transmission shaft, a first rotating wheel, a second traveling drive device, a second transmission shaft, a second rotating wheel, a lifting transmission mechanism, and a lifting drive device. The first transmission shaft is mounted on the main frame; the second traveling drive device is connected to the second transmission shaft; the first transmission shaft and the second transmission shaft are not parallel to each other.

[0004] The aforementioned device enables lifting and reversing functions to be completed with only one drive unit. However, in actual use, after the drive gear drives the drive plate to rise, it is necessary to control and overcome its downward pressure, which places a large load on the drive motor. Prolonged operation under high load will accelerate the wear of internal components of the drive motor. Furthermore, when the motor is under heavy load, a portion of its output power is used to overcome the load rather than for effective work output. This also leads to a decrease in the operating speed of the equipment. Therefore, we propose an integrated lifting and reversing mechanism for a four-way shuttle to solve the above problems. Utility Model Content

[0005] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted by this utility model is as follows:

[0007] A lifting and reversing integrated mechanism for a four-way shuttle includes a drive roller. A control component is sleeved on the surface of the drive roller. The control component includes an assembly cylinder sleeved on the surface of the drive roller. A telescopic cylinder is provided on one side of the assembly cylinder. Multiple mounting slots are fixedly connected to the inner wall of the assembly cylinder. Fixed cylinders are fixedly connected to both sides of the inner wall of the mounting slots. A rotating roller is built into the mounting slot. Torsion springs are sleeved at both ends of the rotating roller. A top seat is sleeved in the middle of the rotating roller. Multiple limiting slots are formed around the drive roller. One end of the top seat is fixedly connected to the rotating roller. The other end of the top seat extends into the limiting slot. A vertical surface is formed on one side of the top seat located in the limiting slot. An elliptical surface is formed on the other side of the top seat located in the limiting slot. The top seat is slidably connected to the wall of the limiting slot. A separation ring groove is formed on the surface of the drive roller. The separation ring groove is in communication with the multiple limiting slots. The top seat is slidably connected to the bottom of the inner cavity of the separation ring groove.

[0008] Preferably, a rotating gear is fixedly connected to one end of the drive roller, and a drive plate is provided on one side of the rotating gear, with the rotating gear meshing with the drive plate.

[0009] Preferably, the drive roller is slidably connected to the inner wall of the assembly cylinder, and the drive roller is rotatably connected to the inner wall of the assembly cylinder.

[0010] Preferably, the output end of the telescopic cylinder is fixedly connected to one side of the assembly cylinder, and a fixed seat is fixedly connected to the tail of the telescopic cylinder. The end of the fixed seat away from the telescopic cylinder is connected to an external fixing component.

[0012] Preferably, the two ends of the rotating roller extend into the two fixed cylinders on both sides, and the rotating roller is rotatably connected to the bottom of the inner cavity of the fixed cylinder.

[0013] Preferably, the torsion spring is placed inside the fixed cylinder, one end of the torsion spring is fixedly connected to the surface of the rotating roller, and the other end of the torsion spring is fixedly connected to the inner wall of the fixed cylinder.

[0014] Preferably, the mounting groove has embedding grooves on both sides, and the top seat is slidably connected to the wall of the embedding groove.

[0015] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0016] The core components of this invention include a drive roller with a rotating gear fixed at one end, which meshes with a drive plate. A control assembly including an assembly cylinder and a telescopic cylinder is sleeved on the surface of the drive roller. The inner wall of the assembly cylinder has an installation groove, a fixed cylinder, a rotating roller, a torsion spring, and a top seat. The drive roller has corresponding limiting grooves and separation ring grooves. A motor drives the rotating roller to rotate forward. With the help of the elliptical surface of the top seat, the drive roller smoothly moves the drive plate upward. After reaching its position, the vertical surface of the top seat prevents the drive roller from rotating, stabilizing the position of the drive plate. This overcomes the drawback of traditional motors requiring continuous downward pressure, significantly reducing motor load, minimizing wear on internal components, extending motor life, improving the effective utilization rate of output power, preventing equipment speed reduction, and improving operating and working efficiency. In actual shuttle operation, this mechanism ensures smooth reversal and lifting, and its design avoids shaking and jamming, allowing the shuttle to transport goods accurately and smoothly, reducing accident risks, and ensuring logistics continuity. Simultaneously, energy consumption is significantly reduced, which is beneficial for energy saving and cost reduction in large-scale warehousing systems. It also extends the shuttle maintenance cycle, reduces downtime and maintenance costs, and comprehensively optimizes warehousing operations. Attached Figure Description

Detailed Implementation

[0023] 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.

[0024] Example: Figures 1-5 As shown, this utility model provides a lifting and reversing integrated mechanism for a four-way shuttle, including a drive roller 1. A rotating gear 101 is fixedly connected to one end of the drive roller 1. A drive plate 102 is provided on one side of the rotating gear 101. The rotating gear 101 and the drive plate 102 are meshed and connected. A control component 2 is sleeved on the surface of the drive roller 1. The control component 2 includes an assembly cylinder 201, which is sleeved on the surface of the drive roller 1. The drive roller 1 is slidably connected to the inner wall of the assembly cylinder 201 and rotatably connected to the inner wall of the assembly cylinder 201. A telescopic cylinder 202 is provided on one side of the assembly cylinder 201. The output end of the telescopic cylinder 202 is fixedly connected to one side of the assembly cylinder 201. A fixed seat 203 is fixedly connected to the tail of the telescopic cylinder 202. The end of the fixed seat 203 away from the telescopic cylinder 202 is connected to an external fixing component. When the drive roller 1 needs to reverse, the telescopic cylinder 202 is activated, and its output end pushes the assembly cylinder 201 to move laterally. As the assembly cylinder 201 moves, the top seat 208 disengages from the limiting groove 212 and enters the separation ring groove 213 that communicates with the limiting groove 212. After the top seat 208 enters the separation ring groove 213, the drive roller 1 is no longer restricted by the top seat 208 when it is in the limiting groove 212, and can freely reverse, thereby realizing the corresponding functional action.

[0025] Furthermore, multiple mounting grooves 204 are fixedly connected around the inner wall of the assembly cylinder 201. These mounting grooves 204 are evenly distributed around the axis of the assembly cylinder 201. Fixed cylinders 205 are fixedly connected to both sides of the inner wall of each mounting groove 204. A rotating roller 206 is housed within each mounting groove 204, with both ends extending into the fixed cylinders 205. The rotating roller 206 is rotatably connected to the bottom of the inner cavity of the fixed cylinder 205. Torsion springs 207 are sleeved at both ends of the rotating roller 206 and are placed inside the fixed cylinders 205. One end of the torsion spring 207 is fixedly connected to the surface of the rotating roller 206, and the other end is fixedly connected to the inner wall of the fixed cylinder 205. A top seat 208 is sleeved in the middle of the rotating roller 206. Multiple mounting grooves 204 are formed around the drive roller 1. A limiting groove 212, one end of the top seat 208 is fixedly connected to the rotating roller 206, and the other end of the top seat 208 extends into the limiting groove 212. A vertical surface 209 is opened on one side of the top seat 208 located in the limiting groove 212, and an elliptical surface 210 is opened on the other side of the top seat 208 located in the limiting groove 212. The top seat 208 is slidably connected to the groove wall of the limiting groove 212. A separation ring groove 213 is opened on the surface of the drive roller 1. The separation ring groove 213 is kept in communication with multiple limiting grooves 212. The top seat 208 is slidably connected to the bottom of the inner cavity of the separation ring groove 213. The motor drives the rotating roller 206 to rotate forward. Since the rotating gear 101 is meshed with the drive plate 102, the rotating gear 101 drives the drive plate 102 to move upward. During this process, the elliptical surface 210 structure of the top seat 208 allows the drive roller 1 to rotate smoothly. Because the elliptical surface 210 adapts to the rotational movement of the drive roller 1 during rotation, it does not obstruct its rotation. Once it reaches the appropriate position, the drive plate 102 stops moving, and the motor also stops working. The vertical surface 209 structure of the top seat 208 then comes into play; the vertical surface 209 engages with the wall of the limiting groove 212 to prevent the drive roller 1 from rotating. This stably holds the drive plate 102 in its current position, eliminating the need for the motor to continuously provide power to overcome the downward pressure of the drive plate 102.

[0026] This design overcomes the problem of traditional drive gears causing the drive plate 102 to rise, requiring the motor to withstand the downward pressure of the drive plate 102 for an extended period. This effectively reduces the motor's load, eliminating the need for prolonged high-load operation, reducing wear on internal components, and extending the motor's lifespan. Because the motor load is reduced, more output power can be used for effective work output, avoiding the problem of reduced equipment speed due to high load. This improves the overall operating efficiency and speed of the equipment.

[0027] This ensures smooth reversing and lifting operations for the shuttle during operation. Through ingenious mechanical structure design, such as the cooperation between the top seat 208 and the limiting groove 212 and separation ring groove 213, the operation vibration or jamming caused by the unstable load of the drive motor in traditional structures is effectively avoided. This makes the shuttle more precise and smooth when moving between shelves and handling goods, reduces the risk of accidents such as goods falling or colliding with shelves, and ensures the continuity of logistics operations.

[0028] Thanks to optimized control of the drive motor load, the shuttle's energy consumption is significantly reduced. During long-duration, high-intensity logistics operations, the motor does not need to continuously output high power to overcome the additional load, resulting in a substantial improvement in energy utilization. This not only reduces operating costs but also saves on power supply infrastructure for large-scale automated warehousing systems, achieving green and energy-efficient warehousing. Furthermore, by reducing wear on internal motor components, the shuttle's maintenance cycle is extended. In traditional structures, the motor frequently operates under high load conditions, requiring frequent replacement of easily worn parts such as bearings and gears. The new lifting and reversing mechanism reduces this risk, minimizes downtime for maintenance, improves the overall operational efficiency of the warehousing system, and saves on a range of maintenance costs, including parts replacement and manual repairs.

[0029] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
