Description

Technical Field

[0001] This utility model belongs to the field of four-way vehicle technology, specifically relating to a four-way vehicle lifting platform. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] In the field of logistics and warehousing automation, the efficient operation of automated systems relies on the smooth transfer of goods between multi-level racks. Four-way vehicle lifts, as key equipment for achieving this vertical transfer function, directly impact the operational efficiency of the entire warehousing system. To meet the needs of different scenarios, four-way vehicle lifts currently employ two main drive schemes to achieve the lifting and positioning of the lifting platform.

[0004] One approach uses a standard geared motor and gearbox to drive a chain or wire rope to move the lifting platform, relying on positioning elements to determine the platform's position. However, in actual operation, this approach suffers from several drawbacks. Due to gaps in the mechanical transmission, load variations during lifting, and inertia, the platform's stopping position after reaching the designated location is unstable and difficult to maintain precisely at the preset height, leading to misalignment between the four-way vehicle track and the lifting platform track. Furthermore, the chain or wire rope itself has elasticity; when the four-way vehicle or cargo is being loaded or unloaded on the platform, it is prone to sinking or rebounding, interfering with normal docking operations and potentially adversely affecting equipment operation.

[0005] Another approach uses servo motors combined with a closed-loop control system to improve positioning accuracy. While this method enables more precise positioning of the lifting platform, thus effectively solving the track docking problem, it requires high-precision servo motors, drivers, and precision guide rails, resulting in higher overall costs. Furthermore, servo systems have stringent installation requirements, such as strict standards for installation levelness and vibration control during operation. The electronic components in the system are also susceptible to interference in complex industrial environments, leading to frequent malfunctions. Once a malfunction occurs, not only are maintenance procedures complex, but the required spare parts are also quite specialized, causing significant inconvenience for daily maintenance and long-term use of the equipment.

[0006] Both of these approaches have limitations in practical applications. Either the lack of positioning stability affects the continuity of operations, or the excessively high requirements for equipment configuration, installation, and maintenance increase the cost and difficulty of use. Utility Model Content To address the aforementioned issues, this utility model provides a four-way vehicle lifting platform that can achieve self-locking, effectively solving the problems of inaccurate positioning of the lifting platform and easy sinking and rebound leading to track misalignment in ordinary geared motor solutions. At the same time, it avoids the drawbacks of servo solutions, such as high cost, stringent installation requirements, and high failure rate.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A four-way vehicle lifting platform includes a lifting platform body. A strong leveling mechanism is provided at the lower end of the lifting platform body. The strong leveling mechanism includes a motor. The drive end of the motor is connected to a drive shaft. Both ends of the drive shaft are connected to drive discs. A seated bearing is provided at the end of the drive shaft. A spherical bearing is provided on the side of the drive disc. An adjustment structure is provided on both the seated bearing and the spherical bearing. A guide seat is provided at the end of the adjustment structure. The end of the adjustment structure is inserted into a locking groove to achieve self-locking.

[0008] As a further technical solution, the drive end of the motor is fixedly connected to the drive shaft, and the motor drives the drive shaft to rotate.

[0009] As a further technical solution, the drive shaft is fixedly connected to the drive disk, and the drive shaft drives the drive disk to rotate; the end of the drive shaft passes through the drive disk.

[0010] As a further technical solution, a seated bearing is installed on the portion of the drive shaft that passes through the drive disc, and the drive shaft drives the seated bearing to rotate.

[0011] As a further technical solution, the adjustment structure includes a rod and a pin shaft, which are movably connected.

[0012] As a further technical solution, the end of the pin shaft passes through the guide seat.

[0013] As a further technical solution, the locking groove is set on the elevator column, and the end of the pin shaft is inserted into the locking groove to achieve locking.

[0014] As a further technical solution, the guide seat includes a first guide member and a second guide member, which are integral structures.

[0015] As a further technical solution, the first guide member is provided with a threaded hole, and the guide seat is installed on the lifting platform body by bolts.

[0016] As a further technical solution, a circular hole is provided on the second guide member, and the end of the pin shaft passes through the circular hole on the second guide member.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are: This invention features a high-leveling mechanism at the lower end of the lifting platform. A motor drives the drive shaft to rotate, which in turn drives the drive disc. The drive disc, in conjunction with the bearing and adjustment structure, allows the end of the adjustment structure to move along the guide seat and insert into a locking groove fixed on the lifting column. In use, after the lifting platform reaches the target position, the motor drives the adjustment structure to insert into the locking groove for self-locking. The cooperation between the locking groove and the adjustment structure forces the platform height to be corrected, avoiding positioning deviations caused by mechanical transmission clearances, load changes, etc. At the same time, the locked state effectively prevents the platform from sinking or rebounding due to the elastic deformation of the chain or wire rope, ensuring precise docking between the four-way vehicle track and the platform track. Furthermore, the high-leveling mechanism consists of a motor, drive shaft, drive disc, bearing with mounting bracket, adjustment structure, guide seat, and locking groove, eliminating the need for high-precision servo motors, drivers, and precision guide rails, significantly reducing overall costs. During installation, the guide seat is fixed with bolts through threaded holes on the first guide component, and the locking groove can be directly aligned and positioned using the end of the adjustment structure, eliminating the need for complex measurements. Maintenance involves only routine inspections and replacements of the mechanical components, simplifying operation. Moreover, the mechanical structure has strong anti-interference capabilities, avoiding malfunctions caused by interference with electronic components in the servo system, thus improving equipment reliability.

[0020] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0021] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses a four-way vehicle lifting platform, such as... Figure 1 , Figure 2 as well as Figure 3 As shown, the system includes a lifting platform body 1. The lifting platform body 1 has a lower end equipped with a leveling mechanism 2. The leveling mechanism 2 includes a motor 21, the drive end of which is connected to a drive shaft 27. Both ends of the drive shaft 27 are connected to a drive disk 22. A seated bearing 28 is provided at the end of the drive shaft 27, and a spherical bearing 23 is provided on the side of the drive disk 22. Adjustment structures 24 are provided on both the seated bearing 28 and the spherical bearing 23. A guide seat 26 is provided at the end of the adjustment structure 24, and the end of the adjustment structure 24 is inserted into a locking groove 3 to achieve self-locking.

[0022] Specifically, a leveling mechanism 2 is installed at the lower end of the lifting platform body 1. The motor 21 drives the drive shaft 27 to rotate, which in turn drives the drive disc 22 to rotate. The drive disc 22 is linked with the bearing 28 and the adjustment structure 24, so that the end of the adjustment structure 24 moves along the guide seat 26 and inserts into the locking groove 3 fixed on the lifting column. In use, after the lifting platform is raised to the target position, the motor 21 drives the adjustment structure 24 to insert into the locking groove 3 to achieve self-locking. With the cooperation of the locking groove 3 and the adjustment structure 24, the platform height can be forcibly corrected to avoid positioning deviations caused by mechanical transmission clearance, load changes, etc. At the same time, the locked state can effectively prevent the platform from sinking or rebounding due to the elastic deformation of the chain or wire rope, ensuring precise docking between the four-way vehicle track and the platform track.

[0023] Furthermore, the high-leveling mechanism 2 consists of a motor 21, a drive shaft 27, a drive disc 22, a bearing 28, an adjustment structure 24, a guide seat 26, and a locking groove 3, eliminating the need for a high-precision servo motor 21, a driver, and precision guide rails, significantly reducing overall costs. During installation, the guide seat 26 is fixed with bolts through the threaded holes 263 on the first guide member 261, and the locking groove 3 can be directly aligned and positioned using the end of the adjustment structure 24, eliminating the need for complex measurements. Maintenance involves only routine inspections and replacements of the mechanical components, simplifying operation. Moreover, the mechanical structure has strong anti-interference capabilities, avoiding malfunctions caused by interference with electronic components in the servo system, thus improving equipment reliability.

[0024] The drive end of motor 21 is fixedly connected to drive shaft 27, and motor 21 drives drive shaft 27 to rotate. Drive shaft 27 is fixedly connected to drive disk 22, and drive shaft 27 drives drive disk 22 to rotate; the end of drive shaft 27 passes through drive disk 22. Figure 4 As shown, the drive shaft 27 passes through the drive disc 22 and is mounted on a seated bearing 28, which drives the seated bearing 28 to rotate.

[0025] In operation, the forced leveling mechanism 2 is activated, and the drive end of its motor 21 drives the drive shaft 27, which is fixedly connected to it, to rotate synchronously. Since the drive shaft 27 is fixedly connected to the drive disk 22, the rotation of the drive shaft 27 directly drives the drive disk 22 to rotate accordingly. After the end of the drive shaft 27 passes through the drive disk 22, the seated bearing 28 installed at this protruding part rotates together with the drive shaft 27. Through the fixed connection between the motor 21, drive shaft 27, and drive disk 22, direct and stable power transmission is achieved, ensuring that the driving force of the motor 21 can be efficiently converted into the operating power of the drive disk 22. like Figure 2 and Figure 5 As shown, the adjusting structure 24 includes a rod body 241 and a pin shaft 25, which are movably connected. The end of the pin shaft 25 passes through a guide seat 26. A locking groove 3 is provided on the elevator column, and the end of the pin shaft 25 is inserted into the locking groove 3 to achieve locking.

[0026] Specifically, when the leveling mechanism 2 is working, when the drive disc 22 rotates and drives the adjustment structure 24, the rod body 241 and the pin shaft 25 can flexibly adjust their relative positions according to the movement trajectory to adapt to the changes in angle and distance during power transmission. The end of the pin shaft 25 passes through the guide seat 26 and moves towards the locking groove 3 on the elevator column under the driving action until it is inserted into the locking groove 3, thereby locking the lifting platform.

[0027] The movable connection between the rod body 241 and the pin shaft 25 allows the adjustment structure 24 to have good adaptability, ensuring that power can be smoothly transmitted to the pin shaft 25; and the way the end of the pin shaft 25 is inserted into the locking groove 3 can directly lock the lifting platform and the elevator column, effectively restricting the vertical movement of the platform, preventing the platform from sinking or rebounding, and ensuring the stability of the platform positioning.

[0028] like Figure 3 As shown, the guide seat 26 includes a first guide member 261 and a second guide member 262, which are integrally formed. The first guide member 261 has a threaded hole 263, and the guide seat 26 is bolted to the lifting platform body 1. The second guide member 262 has a circular hole, through which the end of the pin shaft 25 passes.

[0029] Specifically, the first guide member 261 and the second guide member 262 of the guide seat 26 are an integral structure, resulting in a stable overall structure. When installing the guide seat 26, the threaded hole 263 on the first guide member 261 is used to fix the guide seat 26 to the corresponding position on the lifting platform body 1 using bolts. When the adjusting structure 24 is activated, the end of the pin shaft 25 passes through the round hole on the second guide member 262.

[0030] Furthermore, the bolted connection is easy to operate and reliable, ensuring that the guide seat 26 will not loosen during equipment operation; the round hole on the second guide 262 provides a motion trajectory constraint for the pin shaft 25, preventing the pin shaft 25 from deviating during movement, ensuring that it can be accurately aligned and inserted into the locking groove 3, and providing precise guidance for the locking action of the high-leveling mechanism 2.

[0031] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
