DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-5 The utility model provides a technical solution: an upper entry and exit two-column entrance and exit elevator, comprising a shaft bottom plate 1 and a lifting platform 2, columns 3 are installed on both sides of the top of the shaft bottom plate 1, a support assembly for supporting the lifting platform 2 and limiting its moving trajectory is slidably installed on one side of the column 3, and the lifting platform 2 is installed on the top of the support assembly; the support assembly includes a first support rod 6 slidably sleeved on one side of the surface of the column 3, the lifting platform 2 is installed on the top of the first support rod 6, a second beam 7 is installed between the first support rods 6, and one end of the first chain 5 away from the driving assembly is connected to the top of the second beam 7. The lifting platform 2 is installed through the support assembly and can move on the column 3.

[0026] A second support rod 8 is installed at the bottom of the first support rod 6 and at one side close to the column 3, and a third support rod 9 constituting a triangular stabilizing structure is installed between the second support rod 8 and the first support rod 6. By setting up the triangular stabilizing structure, the firmness and stability of the support assembly can be improved, and the vehicle and the lifting platform 2 can be better supported.

[0027] Furthermore, a sliding assembly for assisting the movement of the supporting assembly is installed at the top and bottom of one side of the supporting assembly, and one side of the sliding assembly is slidably connected to the surface of the column 3. The sliding assembly includes a sliding seat 10 sleeved on one side of the outer side of the column 3, and the sliding seat 10 is respectively installed on the top of the first support rod 6 and the bottom of one side of the second support rod 8. A slide rail 11 is installed on one side of the column 3, and a pulley 12 adapted to the slide rail 11 and slidably engaged with the surface of the slide rail 11 is installed on the inner side of the sliding seat 10. By setting the pulley 12 and the slide rail 11, the moving track of the lifting platform 2 can be limited, and the stability of the vehicle when rising and falling can be improved.

[0028] Specifically, the top of the column 3 is installed with a first crossbeam 4, and the top of the first crossbeam 4 is installed with a driving assembly for providing power for the movement of the lifting platform 2; the driving assembly includes a vertical plate 13 installed on both sides of the top of the first crossbeam 4, and a rotating shaft 14 is rotatably installed inside the vertical plate 13, and both ends of the rotating shaft 14 are sleeved with a reel 15, and the top of the first chain 5 is wound around the top of the reel 15. Both ends of the top of the first crossbeam 4 are installed with a driving motor 16, and the power output end of the driving motor 16 is installed with a coupling 17, and the power output end of the driving motor 16 is connected to the two ends of the rotating shaft 14 through the coupling 17. The power output end of the driving assembly is installed with a first chain 5, and the end of the first chain 5 away from the driving assembly slides through the first crossbeam 4 and is connected to one side of the top of the support assembly; the column 3 is firmly installed on the side of the shaft, providing a solid foundation for the operation of the driving assembly. Driven by the driving assembly, the lifting platform 2 can move up and down smoothly.

[0029] Furthermore, by driving the motor 16, the power output end of the driving motor 16 drives the reel 15 to rotate through the coupling 17 and the rotating shaft 14, the reel 15 reels the first chain 5, and the first chain 5 pulls the second crossbeam 7 and the entire supporting assembly and the lifting platform 2 to move, thereby achieving the purpose of lifting and lowering the vehicle on the lifting platform 2.

[0030] Among them, a counterweight block 18 is slidably installed on the side of the column 3 away from the supporting assembly, and a second chain 19 is installed on the top of the counterweight block 18, and the top of the second chain 19 is connected to the bottom of the second crossbeam 7. When the rotating shaft 14 rotates, the counterweight block 18 will also be driven to move through the second chain 19. The addition of the counterweight block 18 balances the front end weight, effectively reduces the load of the drive motor 16, and improves the operating efficiency.

[0031] It is worth noting that: in this embodiment, two drive motors 16 are connected in series through a rotating shaft 14 for lifting, and no additional synchronization structure is required, thereby simplifying the structure, improving efficiency, and reducing the required installation space. The drive mechanism is installed under the shaft cover plate, and we ensure that there is enough space for installation, so there is no need to install it upward. This provides us with sufficient space to install the counterweight, and the counterweight no longer needs to be installed inside the rectangular tube. This design not only simplifies the processing and installation process, but also improves the operating stability of the equipment.

[0032] The number of columns 3 is reduced to only two, making the processing and installation process simpler and more convenient. In addition, since the installation height does not exceed the entrance and exit platform, the entrance and exit space will not be squeezed, but the available space of the entrance and exit will be expanded.

[0033] When parking your vehicle:

[0034] When the car is safely parked on the lifting platform 2, the switch will automatically detect the vehicle data;

[0035] If the test result meets the standard, the driving component drives the lifting platform 2 to move, and the lifting platform 2 smoothly descends to the designated floor;

[0036] The transporter then transports the vehicle to the designated parking space, or hands it over to the aisle traverse trolley or aisle stacker for parking space allocation;

[0037] When the vehicle is safely transported away, the lifting platform 2 will automatically rise back to the entrance and exit room, ready for the next parking operation.

[0038] When picking up your vehicle:

[0039] The system receives instructions when the user enters the vehicle number outside the entrance and exit gate and completes the payment.

[0040] Aisle trolley or aisle stacker removes the car from the parking space.

[0041] The carrier transports the car to the lifting platform 2 safely and parks it.

[0042] After the carrier completes its task, it leaves, and the drive assembly starts again to raise the lifting platform 2 to the entrance and exit height.

[0043] The outer entrance and exit door is opened, and the user can drive the car out safely at this time.

[0044] The drive assembly is installed below the entrance and exit, which significantly reduces the occupied space. This improvement not only simplifies the structure, but also eliminates the additional synchronization mechanism that was originally required, making the overall structure more concise. In addition, due to the ample space below, we can easily install the counterweight without having to build it into the column, further simplifying installation and maintenance.

[0045] What is more worth mentioning is that since the drive assembly is located below the entrance and exit, when inspection or maintenance is required, you only need to remove the upper cover to easily operate, which greatly improves convenience.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
